[0034] The first receiving plate 2, the second receiving plate 3, and the third receiving plate 4 are arranged sequentially from top to bottom, forming a layered liquid receiving structure that effectively catches the filtrate leaking from the filter press. The inclined design of the multi-layered receiving plates guides the liquid layer by layer to the collection tank 15, preventing the liquid from flowing into the filtered coal cake, reducing costs and improving efficiency.

The three liquid receiving plates can be retracted to a specific position through the linkage structure. When the equipment does not need to receive liquid or is under maintenance, the liquid receiving plates can be completely retracted to avoid occupying extra space.

[0037] like Figure 4As shown, the limiting structure includes a limiting baffle 181 and a limiting block 161. The limiting baffle 181 is disposed at the outlet end of the first conduit 18, and the limiting block 161 is disposed at the top of the first slide rod 16.

[0038] The sliding mechanism includes a mounting plate 10, a drive unit, a transmission structure, and a liquid-receiving connecting plate 12. One end of the mounting plate 10 is connected to the frame 1, and the other end of the mounting plate 10 is connected to the frame 1 via a support structure 20. Both the drive unit and the transmission structure are mounted on the frame 1.

[0039] The transmission structure includes a guide rod 8, a lead screw 9, a moving block, a slider connecting plate 11, and a guide slider.

The transmission structure also includes a protective cover 14, which is arranged above the mounting plate 10 and is used to protect the guide rod 8, the lead screw 9, the moving block, the slider connecting plate 11, and the guide slider.

[0040] How this example works

[0041] The main working process of the device is as follows: when the filter press starts to press the filter plates, the system drives the lead screw 9 through the drive motor 6. Under the guidance of the guide rod 8, the lead screw 9 drives the first liquid receiving plate 2 through the liquid receiving connecting plate 12, so that the first liquid receiving plate 2 cooperates with the first guide tube 18 through the first slide rod 16 and extends along the guide rod 8. When the first slide rod 16 advances to contact the limiting baffle 181 on the second liquid receiving plate 3, the lead screw 9 continues to advance. At this time, the first slide rod 16 drives the second liquid receiving plate 3 through the limiting baffle 181, so that the second liquid receiving plate 3 continues to extend along the forward direction of the guide rod 8 with the cooperation of the second slide rod 17 and the second guide tube 19. When the second slide rod 17 advances to contact the limiting baffle 181 on the third liquid receiving plate 4, it means that the first liquid receiving plate 2 has reached the maximum position of the set stroke of the screw 9. The entire device is now located below the filter press flap. When the filter press starts the feeding and high-pressure pressing process, if the flap leaks liquid, the liquid will fall above the liquid receiving plate and guide the filtrate into the filter press collection tank 15, thereby preventing the filtrate from falling into the already formed coal cake. When the high-pressure pressing process ends, the screw 9 begins to return, and the liquid receiving plate retraction process is similar to the extension process.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
