As shown in fig. 1 to 6, the filter press device has a frame 23, two parallel slide rails 16 are provided on the frame 23, a support plate 18 is fixed at one end of the slide rails 16, a mounting hole 25 is reserved in the center of the support plate 18, the outlet of a liquid supply pipe 19 is mounted on the mounting hole 25, and the liquid supply pipe 19 is connected with a high-pressure pump for supplying liquid to be filtered with pressure. And a pressing plate 24 is arranged at the other end of the slide rail 16, and the pressing plate 24 is connected with the driving device hydraulic cylinder 17 and can reciprocate on the slide rail 16 under the pushing of the hydraulic cylinder 17. Be equipped with a plurality of filter 100 between backup pad 18 and clamp plate 24, filter 100 can move and compress tightly in proper order on backup pad 18 along slide rail 16 under the promotion of clamp plate 24, and backup pad 18 and clamp plate 24 are sealed filter 100 from both sides moreover to filter 100 seals at the edge each other, like this when supply line 19 waits for the filtering liquid with natural pond liquid and sends into in the filter, can effectively prevent the weeping. Below the filter plate 100, a liquid collecting tank 21 is provided for receiving the filtrate flowing out after being filtered by the filter plate, and the liquid collecting tank 21 is obliquely arranged and connected to the liquid storage tank 22 at the lower end.
The filter plate 100 includes the plate body 1, and the plate body 1 generally is square board, is connected with frame 2 around the plate body 1, and frame 2 is to the both sides protrusion of plate body 1, all encloses into a groove room 3 by the frame in every side of plate body 1 promptly, and when two plate bodies 1 were pieced together side by side, this two plate bodies 1 frame 2 all around closely docked, can enclose synthetic dress liquid cavity. Leave a through-hole at the center of plate body 1, plate body through-hole 4 promptly, the both sides of plate body 1 are equipped with a plurality of recesses 5, are equipped with out liquid channel 6 on frame 2, and the recess 5 of plate body 1 both sides all is linked together with out liquid channel 6, and it communicates the frame 2 outside to go out liquid channel 6, and liquid gathers and flows out through out liquid channel 6 in recess 5 promptly. The two sides of the plate body 1 and the frame 2 are covered with filter screens, wherein one side is covered with a first filter screen 7, the other side is covered with a second filter screen 8, a first filter screen hole 701 is reserved in the center of the first filter screen 7, a second filter screen hole 801 is reserved in the center of the second filter screen 8, the inner periphery of the first filter screen hole 701 is connected with a first outer periphery 901 of one end of the cloth tube bag 9, the second filter screen hole 801 is connected with a second outer periphery 902 of the other end of the cloth tube bag 9, and the cloth tube bag 9 penetrates through the plate body through hole 4. The plate body 1 and the frame 2 are wrapped from the plate body through hole 4 to the periphery by the first filter screen 7, the second filter screen 8 and the cloth barrel bag 9. When filter 100 by pressfitting together, natural pond liquid flows in and enters into cloth tube bag 9 from liquid supply pipeline 9 in, then flow into between two filter screens of two adjacent filter from the port department of cloth tube bag 9, then pass these two filter screens respectively and enter into the recess 5 on plate body 1 respectively and collect, then flow from liquid outlet channel 6, and the residue in the natural pond liquid just can be stained with the outside of hanging at first filter screen 7 and second filter screen 8, when filtering the back filter 100 and separating each other, can directly wash the residue of being stained with and hanging in the filter screen outside with water, and is very convenient. The frame 2 is provided with supports 14 on both sides, and rollers 15 are provided on the supports 14, the rollers 15 being located on the rails 16, so that the filter plate 100 can move freely on the rails 16. The outlet channel 6 is connected to a tap 13, which tap 13 is adapted to leading filtrate to a liquid collection tank 21 below.
When filtering, thereby the liquid dynamic pressure that 1 both sides of plate body born generally has the difference and leads to the atress unbalanced, plate body 1 separates and damages with frame 2 easily like this, consequently in an embodiment, both sides at plate body 1 set up a plurality of bellied round platforms 11, the height of round platform 11 matches to the convex thickness of side with frame 2, the top surface of round platform 11 and the side parallel and level of frame 2 promptly, when two filter amalgamations, not only two adjacent frame 2 laminates, round platform 11 on two adjacent plate bodies 1 also corresponds the laminating, make the plate body atress balanced like this, thereby be difficult for damaging with frame 2 separation.
In another embodiment, the plate body 1 is provided with a transverse and longitudinal arrangement of cylinders 12 on both sides, the gap between two adjacent cylinders 12 forming said recess 5. Thus, the grooves 5 are uniformly dispersed, and the filtrate is easier to collect.
