This invention aims to provide novel means whereby a stench proceedlng from a drler may be done away Wltll, especial reference being had to drlers in which blood,

'tankage, fish meal, grain, and the like, are

handled. The invention aims to provide a deodorizer of novel construction, and to provide novel means for supplying fluid pressure to the conduit that carries the vapors and the like from the drier to the deodorizer.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of what is shown by the invention herein disclosed, within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in elevation, a device constructed in accordance with the invention;

Figure 2 is a: longitudinal section through the deodorizer;

Figure 3 is a transverse section through the drier;

Figure 4 is a fragmental section on the line 44 of Figure l;

Figure 5 is a fragmental longitudinal section of one of the nozzles.

The numeral 1 designates a drier of the kind used for drying grain, blood, fish meal, tankage, and the like. The drier 1 includes a receptacle 2 about which is located a shell 3, the space between the shell 3 and the receptacle 2 constituting a steam jacket 4. The shell 3 is supplied with a steam inlet pipe 5 discharging into the steam jacket 4.

A shaft drier 1 and carries a rotatable agitator 7 which may comprise paddles. The numeral 8 designates a conduit leading from the receptacle, at the top thereof, to the deodorizer 20, which will be described hereinafter.

6 is journaled for rotation in the 1929. Serial No. 378,513.

The conduit 8 may be made, for the most part, out of stockmaterials. The part 10 ofthe conduit 8 which is immediately adjacent to the drier 1 is somewhat greater in diameterthan the'part 11 which is adjacent to the deodorizer 20. At the place where the parts 10 and 11 of the conduit 8 are joined together, there is a reduced throat 12, shown in Figure 4. The numeral 14 designates a fluid pressurepipe which may carry steam from any desired source, compressed air, etc.

embodiment of the invention,

In the present however, the lower end of the fluid pressure pipe 14 communicates with the steam jacket 4 of the drier 1. At its upper end, the steam pressure pipe 14 has a nozzle 15 located in the part 10 of the conduit 8 and discharging into the throat 12. A strainer 16 is located in the. pipe 14. In the pipe 14 is dis posed a valve 17 which is under the control of an operator. The part 11 of the conduit 8 is connected to one end of a T 9, the vertical branc' of the T 9 being connected to the tapered upper end 18 of the cylindrical body 19 of the deodorizer 20. On the outer end of the horizontal branch of the T 9 there is a detachable cap 25, which may be removed to permit an operator to get at the conduit 8 and clean it out. 7

j The body 19 of the deodorizer 20 has a ta pered lower end 21 discharging through a trap 23 into a pipe 24 which may lead to a sewer (not shown). The deodorizer 20 is supported on longitudinally adjustable legs 22 The numeral26 designates a water supply pipe in which is interposed a valve 27 under the control of an operator. A strainer 28 is located in the pipe 26. The pipe 26 extends downwardly through the vertical branch of the T 9, into the body 19 of the deodorizer 20. The lower end of the pipe 26 is connected to a tubular nozzle 29, the lower end of which is closedby a cap 30. The nozzle 29 may be located at the axis of the body 19 and the deodorizer 20. The nozzle 29 is provided with openings 31 arranged in longitudinal lines, as shown in Figure 2; penings are staggered around the nozzle 29, as Figure 5 will show. The openings 31 in the norzle 29 slant downwardly and outwardly, as can be seen in Figure 5.

The cap 25 can be removed, and then the nozzle 15 and the throat 12 of Figure 4; will facilitate the cleaning of the conduit.

In practical operation, the material to be dried is placed in the receptacle 2 of the drier. The steam in the jacket a has a pressure of from forty pounds to eighty pounds to the square inch with a temperature of 220 F. up, and the moisture in the material in the drier is driven off, the moisture running from 30 to 80 percent by weight. The agitator 7, of course, lreeps the material in the drier stirred up whilst the drying operation is going on. When the moisture becomes hot enough, it rises in the drier and goes over through the conduit 8, the passage of the vapor through the conduit 8 being accelerated because fluid pressure is discharged from the nozzle 15 into the throat 12, the pressure fluid, in the present eml odiment of the inven tion, being steam from the steam jacket 4 of the drier. ater from the pipe 26 flows outwardly through the holes 31 in the nozzle 29 and is discharged into the body 19 of the deodorizer 20, the vapors entering the deodorizer by way of the T 9. The water discharged from the nozzle 29 absorbs the moisture that the deodorizer has received from the conduit 9 and the waste water runs away through the trap 28 and the pipe 24 to a sewer (not shown).

The construction is such that the ranksmelling vapor proceeding from the drier is taken care of, there being no objectionable odor in and about the entire apparatus. The device is simple in construction and may be manufactured at a small cost.

Having thus described the invention, what is claimed is:

In a device of the class described, a deodorizer comprising a tubular body having an outlet, a T connected to the top of the body and having oppositely disposed branches, one of which is connected to a source of gas to be deodorized, a water supply pipe and a nozzle extended down through the T, the nozzle discharging into the body, a conduit connected to said one of said oppositely disposed branches of the T, a removable cap on the other of said oppositely disposed branches of the T, a reduced throat in the conduit, and a fluid pressure pipe entering the conduit and discharging through the throat directly toward the removable cap, the throat and the fluid pressure pipe acceleratingthe flow of gas to be deodorized, when the cap is in place, and facilitating a cleanof the conduit when the cap is removed.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

ARTHUR WHEELER PELPHREY.
