Abstract
The invention discloses a filtering plate which is aiming at providing a filtering plate which has simple structure, small space usage, light deadweight, short construction period, low cost and low energy consumption, and is uneasy to leak sand, can filtrate in double directions-positive and negative directions and can evenly distribute water and gas. The invention contains a plurality of table flaps (1). The table flaps (1) are connected together. A plurality of water and gas distributing holes (3) are arranged on the slab of the table flaps (1). The invention can be widely applied in water treatment filtration process.
Description
Technical field
The present invention relates to a kind of filtering board, relate in particular to a kind of filter plate that is used for water and air distributing in the water treatment filtering technique of giving.
Background technology
At present, in giving the water treatment filtering technique, all adopt water and air distributing systems such as perforated pipe, filter block, filter, wherein perforated pipe water and air distributing system is more of a specified duration service time, but because water and air distributing is inhomogeneous, the energy consumption height, problems such as leakiness sand seldom adopt now; The gas that pottery system such as filter block owing to can not adapt to now generally uses is towards technology, therefore also less employing; Filter water and air distributing system has solved the problem that systems such as perforated pipe, Ceramic Tiles exist, and with the obvious advantage, since last century Mo extensive use, but also there is following shortcoming in this system: the cost height, and complex structure, and long construction period can not reverse filtrations; In recent years the overall plastic compound filter block compact conformation of Chu Xianing, it is little to take up room, but the cost height, and the water and air distributing uniformity is good inadequately.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and it is little to take up room, from heavy and light, and short construction period, cost is low, and energy consumption is low, and leakiness sand not can be positive and negative bi-directional filtered, the uniform filtering board of water and air distributing.
The technical solution adopted in the present invention is: the present invention includes several flaps, described flap is connected and is integral, and described flap wooden partition is provided with some water and air distributings hole.
Described flap cross section is a zigzag.
The junction, bottom of described flap is provided with the platform supporting part.
Described flap cross section can also be for corrugated.
Described water and air distributing hole is circular hole or strip hole.
The invention has the beneficial effects as follows: because the present invention is made up of several same flap, so simple in structure, consumptive material is few, from heavy and light; Described flap is connected and is integral on the support that directly is fixed on the filter tank, and support is arranged on the base plate of filter tank, and support can adopt reinforced concrete or metal material manufacturing, and is simple in structure, and it is little to take up room, short construction period, and cost is low; Because the aperture, water and air distributing hole on the flap is less, recessed position at flap is provided with the gravel supporting layer, on supporting layer top filter material layer is set again, so leakiness sand not, and can be positive and negative bi-directional filtered, because aperture, water and air distributing hole is little, be evenly distributed, and, therefore can guarantee that water and air distributing is even by the row distribution again of gravel supporting layer.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the structural representation of the embodiment of the invention two.
The specific embodiment
Embodiment one:
As shown in Figure 1, the present invention includes several flaps 1, described flap 1 cross section is a zigzag, some described flaps 1 are connected to be integral and are fixedly installed on the support 2, described support 2 adopts armored concrete or metal material to be horizontally set on the base plate of filter tank, described flap 1 wooden partition is provided with some water and air distributings hole 3, described water and air distributing hole 3 is a circular hole, can certainly adopt the hole such as the strip hole of other shape as required, the junction, bottom of described flap 1 is provided with platform supporting part 4, described platform supporting part 4 is provided with the gravel supporting layer, and the top of described gravel supporting layer is provided with filter material layer.
Described flap 1 can adopt the engineering plastics injection mo(u)lding, also can adopt metal material such as corrosion resistant plate punch forming.
During use, the present invention directly is fixed on the support 2 on the filter tank, do not need to set up in addition supporting filter plate, junction, bottom at flap 1 is provided with platform supporting part 4, the gravel supporting layer is set on the platform supporting part 4, on supporting layer top filter material layer is set again, the lower space of flap 1 is the water and air distributing layer, after water, gas enter the water and air distributing layer by the water and air distributing pipe duct, by the water and air distributing hole 3 and the gravel supporting layer water and air distributing of flap 1, so it is little to take up room, short construction period, cost is low, leakiness sand not, and water and air distributing is even.
Embodiment two:
As shown in Figure 2, described flap 1 cross section of present embodiment is corrugated, and other structures are identical with embodiment one.
The present invention can be widely used in the water treatment filtration process.
