Preferably, the first filter sheet and the second filter sheet are made of flexible materials.
Preferably, the upper ends of the filter plate and the support plate are respectively fixedly connected with a handle.
The utility model has the beneficial effects that:
1. the sealing problem when the filter plate frames are connected is solved;
2. the filter screen can be prevented from being deformed to generate tearing phenomenon;
3. the filter screen can be limited and simultaneously connected more firmly;
4. the filter plate frame sealing structure has the advantages of preventing raw material liquid and washing water from leaking, further avoiding liquid leakage during washing filter cakes, improving the accuracy of experimental data, and being convenient to install, disassemble and wash and beneficial to operation.

Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
When the embodiment is used, the plate type filter is required to be lapped on the supporting rods through the lap joints 7 at the front end and the rear end, the supporting rods are arranged in parallel, the plate type filter generally adopts a plurality of groups to carry out heavy filtering, so as to ensure the filtering effect, or simultaneously, the plurality of groups work together to increase the filtering speed, when the embodiment is installed, the filter plate 1 is firstly placed on the supporting rods, then the first filter disc 3, the second filter disc 4 and the supporting plate 5 are sequentially placed outwards at the left side and the right side of the filter plate 1, the positions of the lap joints 7 at the front end and the rear end of the filter plate 1, the first filter disc 3, the second filter disc 4 and the supporting plate 5 are corresponding, after the filter plate 1 is placed, the left end and the right end of the filter plate 1 are respectively provided with the filter screen 2, then the positions of the through holes 8 in the middle of the filter plate 2 and the filter plate 1 are corresponding, and the diameters of the through holes 8 in the filter plate 1 are smaller than the diameters of the filter screen 2, then, pressure is respectively applied to the outer sides of the supporting plates 5, so that the supporting plates 5 are close to the positions of the filter plates 1, all parts are attached under the action of the pressure, the filter screen 2 cannot fall under the action of the pressure because the diameter of the filter plates 1 is larger than that of the filter plates, then, the pressure continues to be applied after the preliminary positioning, because the first filter disc 3 and the second filter disc 4 are respectively made of flexible materials, certain deformation exists under the action of the pressure, the deformed parts of the first filter disc 3 are embedded in the filter plates 1, then the outer edges of the filter screens 2 are extruded, the outer edges of the filter screens 2 cannot fall off, the interception net 9 in the middle of the first filter disc 3 plays a certain blocking and limiting role on the filter screens 2, the through holes 8 in the middle of the second filter disc 4 can contain a certain deformation amount of the filter screens 2, and meanwhile, the limit ring 10 in the middle of the support plate 5 plays a role in limiting the deformation of the filter screen 2.
The first filter 3 and the second filter 4 are connected in an adhesive manner, and the first filter 3 presses the filter screen 2 and is tightly attached to the filter plate 1, so that the filter screen 2 is prevented from leaking by deformation of flexible materials, and the second filter 4 is tightly attached to the support plate 5 to play a sealing role.
The water through holes 6 respectively formed in the filter plate 1, the first filter plate 3, the second filter plate 4 and the support plate 5 are used for liquid circulation, the inner side of the filter plate 1 is communicated with the water through holes 6, when the filter plate is in operation, liquid is conveyed through the water through holes 6, firstly enters the through holes 8 on the inner side of the filter plate 1 through the communicating parts on the inner side of the filter plate 1, then the left end and the right end of the filter plate 1 are outwards discharged after being filtered by the filter screen 2, and sundries in the liquid are blocked by the filter screen 2 and remain on the inner side of the filter plate 1.
