Description
Technical field
The present invention relates to a kind of barrier film pump head that is used for homogenizer or high-pressure service pump, it comprises a pump head that is encapsulated in (enclose) pump case at least; This barrier film pump head further comprises product chambers, and this product chambers has the entrance and exit that supplies the product turnover, also comprises being mounted with piston in it so that the hydraulic chamber of controlling, and this product chambers and this hydraulic chamber separate through double-deck barrier film.
Background technique
Homogenizing is a kind of industrial treatment method used the reasonable time, its objective is, with the fat breast for example in the milk maximum fat globule split into less fat globule, make fatty emulsus attitude stable through such mode.Therefore, be example with milk, homogenizing means and has stoped condensing of butterfat, and today, more most of consumption milk all homogenized.
Homogenize and take place by machine treatment usually; The result is that the fat breast is compelled to pass through very narrow gap at a high speed under high incoming pressure; Especially cause the fat globule of fat breast to break subsequently because of turbulent flow, turbulent flow can take place when the fat breast leaves the gap with high speed.Static pressure is hanged down in after the gap, forming at a high speed of liquid, so the hole bubble can produce.When the bubble implosion of hole, will produce extremely high and of short duration pressure pulse, produce the required immense strength of fat globule membranolysis thus.
Retrievable homogenizer is made up of reciprocating pump and back pressure apparatus in essence on the existing market, and wherein reciprocating pump produces the required high pressure that homogenizes, and in fact occurs in the back pressure apparatus and homogenize.This reciprocating pump is common mechanical structure, and it is converted into linear motion with rotatablely moving of drive motor, and the piston of this reciprocating pump is by this linear motion drive controlling.
Provide the piston packing of the high pressure that produces in the antagonism machine on the piston of reciprocating pump.Because in food product environment, can not remove lubricated sealing circle, thereby cause for example portioned product seepage, so the service life of sealing circle becomes and lets the unacceptable weak point of people; Except the shortcoming of health aspect, this will cause more product loss.In addition, work in order to make seal ring, they also must be made up of a kind of relatively softer material, although they will bear uniform pressure with the iron and steel in the mechanical realization on every side, this also be their service lifes lack facilitate factor.
In addition, the existing used reciprocating pump of homogenizer shows and forges pump seat (block), and the manufacturing expense of forging pump seat is extremely expensive.
Diaphragm pump is by hydraulic driving, and just diaphragm pump has barrier film, the hydraulic fluid that this barrier film is extracted by habitual reciprocating pump, and such diaphragm pump can not run into the sealing difficult problem as reciprocating pump.This is that the seepage of hydraulic fluid has been lubricated seal ring and piston because extract the seepage that piston packing on the piston of hydraulic fluid can allow little, controlled hydraulic fluid, since mode and the product of hydraulic fluid through double-deck barrier film separates.Such sealing design has given the almost piston seal service life of endless.
The barrier film pump head can not normally be applied on the homogenizer; Because for consistent with the stroke capacity of the plug of both surviving; The diameter of barrier film must be extremely big, the result be have the reciprocating pump of barrier film pump head need be than the big a lot of piston space centre distance of usual piston mechanism piston space centre distance.
Barrier film both sides pressure in the barrier film pump head equates that because identical pressure is born on its septation both sides, barrier film is divided into product chambers and hydraulic chamber with this pump head.The result is, these barrier film both sides do not have pressure difference, and piston packing then bears different pressure usually.Therefore, this barrier film can be processed by the material that can not bear the high pressure of generation originally, and consequently the barrier film pump head can bear the higher pressure of pressure that possibly run into than habitual reciprocating pump far away.
U. S. Patent 6,174,144 have described a kind of device that uses diaphragm pistonpump to homogenize.In this patent, its some pump heads that laterally arranged are to form hydraulic chamber and product chambers, and one of them product chambers and a hydraulic chamber are separated by barrier film independently of each other.Piston moves in each hydraulic chamber separately, simultaneously with barrier film transfer to, make them parallel with piston.In this embodiment, if give diaphragm piston stroke capacity required diameter space, pump seat will be far away more greatly and more expensive far away.This is because the cross section of pump seat must be the same with the diameter of barrier film big, also will add the fixedly required space of barrier film.Similarly, this mode of execution will cause disadvantageous relatively high pressure sealing of barrier film and big relatively flow loss.
Summary of the invention
An object of the present invention is to obtain the advantage that is used to homogenize, enjoy all diaphragm pumps, the not too big barrier film pump head of size of while barrier film pump seat.
Further purpose of the present invention is that the pump seat manufacturing is become simpler far away, and therefore more economical far away.
Another purpose of the present invention is to realize more favourable barrier film high pressure sealing.
The purpose that the present invention also has is to let the flow loss between piston and the film drop to minimum.
A purpose that also has of the present invention is on habitual reciprocating pump, the barrier film pump head to be installed, and keeps the centre distance of piston space.
According to the present invention, these or other purpose has realized that since this diaphragm pump head type described in introducing has provided technical characteristics, this technical characteristics is that said barrier film becomes 15-75 ° of location with the length direction of said piston.
Preferred implementation of the present invention further has the described technical characteristics of appended dependent claims.
Description of drawings
Describe a kind of preferred implementation of the present invention in detail below with reference to accompanying drawing,
In the accompanying drawing:
Fig. 1 shows the structure skeleton diagram of barrier film pump head.
Fig. 2 shows the partial cross section plan view of pump seat of the present invention.
Fig. 3 shows the partial cross section side view of pump seat of the present invention.
Accompanying drawing has only provided understands the present invention necessary part and details, and the location of pump seat is known to those skilled in the art in the homogenizer, so no longer illustrate.
Embodiment
Fig. 1 shows barrier film pump head 1, as it shows substantially.Barrier film pump head 1 comprises pump case 2, and pump case has product chambers 3 and hydraulic chamber 4 for 2 li, and product chambers 3 is separated through barrier film 5 with hydraulic chamber 4.
Product chambers 3 is connected with product inlet 20, and product inlet 20 has valve 6.Product chambers 3 also is connected with products export 7, and products export 7 has valve 8.
Piston 9 moves in hydraulic chamber 4, is filled with hydraulic fluid in the hydraulic chamber 4, preferred extending oil.Piston 9 is tightly connected through Sealing 10 with pump case 2, and Sealing 10 affords high pressure and constantly lubricated by hydraulic fluid.The excessive fluid of hydraulic fluid leads to hydraulic fluid container 12 via pipeline 11, and hydraulic container 12 replenishes hydraulic fluid for hydraulic chamber 4 through pipeline 13 and safety check 14 where necessary.
Barrier film 5 is processed by thermoplastic material usually, the verified material that can together use with food of PTFE (teflon) or other for example, and the normal service life-span of such barrier film 5 is 8000 hours.Because barrier film 5 is by hydraulic support and pressure equilibrium, promptly the pressure on its both sides is the same, so it can not bear extreme strength and pressure.Because barrier film 5 is used for food production equipment, so need to use double-deck barrier film 5.Between barrier film 5 is two-layer is vacuum, and an end of vacuum is connected with safety check 15, and the other end is connected with capillary tube 16, capillary tube 16 and then be connected with pressure transducer 17.If one of barrier film 5 bilayers break or rupture leak, the pressure in the capillary tube 16 will raise, and it is defective that pressure transducer 17 will give the alarm with prompting barrier film 5.
Because the reason of material engineering technology, barrier film 5 can only move the distance of its diameter 1/10th approximately, cause the diameter of barrier film 5 to determine the stroke capacity of pump head 1, the i.e. displacement of piston 9 thus.The specific stroke capacity of process need because homogenize is so diaphragm diameter is necessary to give piston 9 identical length of stroke as conventional reciprocating pump.
In order to offer barrier film pump head 1 space in the existing homogenizer, can see significantly that from Fig. 2 barrier film 5 becomes 15-75 ° of location with the length direction of piston 9.More excellent ground, barrier film 5 becomes 45 ° of location with the length direction of piston 9, becomes 15-75 ° and more excellent become 45 ° with the length direction of piston 9 through barrier film 5 is orientated as, and the size of pump case 2 will drop to minimum.For example, in the pump case 2 of a correspondence, become 90 ° of location if compare barrier film 5 with the length direction of piston 9, barrier film 5 possibly have about 30% diameter.The mode that barrier film 5 is arranged according to the present invention can not influence the size of machine generally.Because barrier film 5 has the physical activity restriction on its activity direction, connect required exceptional space to obtain screw so cause to strengthen usually its diameter.
Since barrier film 5 and the length direction of piston 9 are positioned to 15-75 ° and more excellent become 45 °, can make barrier film 5 obtain better high pressure sealing, will be more favourable far away with barrier film 5 relevant such flow angle.In addition, because this favourable flow angle, the flow loss between piston 9 and barrier film 5 diminishes, and this has reduced the overall energy consumption of homogenizer.
Pump seat 18 is made up of the pump case 2 of the included some of homogenizer, three pump cases has been shown among Fig. 2 has united formation pump seat 18.Each pump case 2 is all supported by adjacent pump case 2, and this makes pump case 2 and becomes possibility for a short time than those pump cases that use in conventional reciprocating pump or the diaphragm pump.Have only pump seat 18 outmost two parts to need reinforcement., just can avoid to when pressurizeing, not producing leakage pump case 2 gangs according to the present invention, each pump case 2 must enough firm requirements.
The present invention allows to pass through tie-rod 19 with pump seat 18 gangs, and tie-rod 19 has enough elastic performances in this association, and such uniting simultaneously occupies littler space.Become 15-75 ° and preferably become 45 ° with the length direction of piston 9 through location barrier film 5, when pressurized membrane 5,30% masterpiece is used tie-rod 19 approximately less, and tie-rod 19 is with pump seat 18 gangs.The fixedly tie-rod of pump seat (not shown) acting in conjunction in these tie-rods 19 and the crank mechanism, this not shown tie-rod are fixed on pump seat on the sealing surfaces of barrier film 5 also with it sealing.Low 30% the power of acting on the tie-rod 19 is brought lower materials consumption, makes that also the size of tie-rod 19 and pump seat 18 is littler.
The present invention makes the quantity that reduces tie-rod 19 or connecting bolt become possibility; Cause the size of pump seat 18 outsides little more a lot of thus, for fastening habitual barrier film pump head 1 needs a large amount of bolts and the circulation fastening area relevant with bolt than habitual circulation barrier film pump head 1.The present invention also lets use tie-rod 19 replace bolts to connect pump seat 18 becomes possibility.Through such method, also can obtain the required elastic performance of association.Since the invention enables essential bolt or tie-rod 19 quantity to tail off, also will have living space in pump seat 18, to integrate essential hydraulic fluid pipeline.
When the piston in the diaphragm pump 9 moved backward, the space of hydraulic chamber 4 increased, this so that cause that barrier film 5 and piston 9 are the same to be moved to same direction, the valve 6 on the product inlet 20 is opened, product is sucked in the product chambers 3.Piston 9 in diaphragm pump moves forward, and reduce in the space of hydraulic chamber 4, this so that cause that barrier film 5 and piston 9 are the same to be moved to same direction, the valve 8 on the products export 7 is opened, product leaves product chambers 3 through products export 7.
Because double-deck barrier film 5 causes product and hydraulic fluid to separate hermetically and is separate, so no longer need make specific aseptic homogenizer from now on.It is the same in the aseptic homogenizer to coexist, and piston 9 not part contacts with product.Piston 9 does not need sterilization, and the total sterilization time of homogenizer can reduce.Therefore, the steam consumption of aseptic homogenizer minimizes.
Diaphragm pump majority in the existing homogenizer is typically provided with water-cooled piston 9, and water is constantly with its flushing, and purpose is in order to cool off and to lubricate, increasing the service life of Sealing 10 thus.Through replacing habitual reciprocating pump with diaphragm pump, the needs of having eliminated water-cooled also can fundamentally reduce the water consumption of homogenizer.
Because be provided with double-deck barrier film 5 according to barrier film pump head 1 of the present invention; So the 5 two-layer while of barrier film, problematic possibility was non-existent; The result is just in case alarm indication barrier film 5 goes wrong, and also need not stop to produce, and can replace barrier film 5 at the normal stopping period of producing.Certainly, according to conventional way, should behind given Preset Time, change barrier film 5.
Usual homogenizer operates under the pressure of 250bar mostly usually, has by contrast under can be the far away higher pressure of the homogenizer of barrier film pump head 1 to operate, if barrier film 5 is especially true when being made by metal.Therefore possibly make in the future the homogenizer that can under high considerable pressure, operate than existing technology.
Like aforementioned description clearly, the present invention has realized enjoying the homogenizer barrier film pump head of all advantages of diaphragm pump and can it being retrofitted in the existing homogenizer.Because the angled relation of the length direction of barrier film and piston, so can obtain the pump seat littler than the pump seat in the existing diaphragm pump.In addition, pump seat is made more easily, thereby more economical, and is simultaneously littler to the influence of environment in the mill.Barrier film pump head according to the present invention has further been showed good barrier film high-pressure tightness and has reduced flow loss that these have all reduced the energy loss of homogenizer generally.
