A filter plate 8 is plugged into the inner wall of the slot 6, and the number of the filter plates 8 is set to be multiple. By setting multiple filter plates 8 to filter the liquid, the filtering effect is improved. The top of the filter plate 8 is fixedly connected with a handle 18 for conveniently removing the filter plate 8, and a disassembly mechanism is arranged inside the filter plate 8.

[0033] Reference Figure 3 - Figure 5 The reinforcement mechanism includes a fixing frame 7, a pull ring 19 is fixedly connected to the top of the fixing frame 7 for the convenience of the staff to take out the fixing frame 7, the fixing frame 7 is inserted into the inner wall of the slot 6, and a convex block 9 is fixedly connected to the side of the fixing frame 7 away from the center of the mounting frame 1 for positioning, and a groove 10 matching the convex block 9 is arranged inside the mounting frame 1, and the convex block 9 is inserted into the inner wall of the groove 10, and an elastic spring sheet 11 is installed on the inner wall of the side of the fixing frame 7 close to the center of the mounting frame 1, and the spring sheet 11 is naturally arranged in an arc shape when not subjected to external force. , and protrudes toward the direction close to the filter plate 8. The side of the spring piece 11 away from the fixing frame 7 contacts the surface of the filter plate 8. When the filter plate 8 is installed, the spring piece 11 is squeezed, so that the spring piece 11 is deformed by force and completely enters the interior of the mounting frame 1. At the same time, the spring piece 11 will apply a reaction force to the filter plate 8 to reinforce the filter plate 8, avoid the impact force of the water flow to drive the filter plate 8 to move, effectively reduce the vibration and displacement of the filter plate 8, and the fixing frame 7 is fixedly connected to the mounting frame 1 by fastening bolts 12 to improve the stability of the support.

[0034] Reference Figure 2 - Figure 4The protrusion 9 is set to an inclined state.
