[0018] Furthermore, the outer surface of each of the slide plates is fixedly connected to two side plates, and the outer surface of each of the side plates is slidably connected to the ear plate through a hollow groove opened inside the ear plate.

[0019] Through the above scheme, the skateboard is restricted to prevent the skateboard from sliding and falling off, thereby increasing the stability of the skateboard movement.

[0021] Through the above solution, the hydraulic cylinder drives the pressing plate to press the frame, so that the frame can be pressed as a whole.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The plate and frame filter device drives the positioning rod to rise and fall by rotating the screw rod, so that the positioning rod can move into or out of the positioning hole, and then the slide plate is moved, so that the frame and the ear plate can be easily disassembled for cleaning or maintenance, the cleaning or maintenance efficiency of the frame can be improved, and the flexibility and practicality of the filter device can be improved. This solves the problem that the existing plate and frame filter device is not convenient for disassembly, maintenance or cleaning of the plate and frame, and the slag removal or maintenance is limited by the position of the plate and frame, which affects the cleaning or maintenance efficiency.

[0034] See also Figure 2 A first spring 6 is fixedly connected between two adjacent ear plates 5. Each first spring 6 is sleeved on the outer circumferential surface of the guide rod 3. The first spring 6 applies a thrust to the adjacent ear plates 5, so that the frame 4 can be quickly separated during cleaning.

[0035] See also Figure 4 and Figure 5A screw rod 9 is rotatably inserted inside each ear plate 5, and a positioning rod 10 is threadedly connected to the outer circumferential surface of the screw rod 9. A positioning hole 11 is opened inside each slide plate 8. The outer circumferential surface of the positioning rod 10 is slidably inserted with the slide plate 8 through the positioning holes 11. The positioning rod 10 is driven to move into or out of the positioning hole 11 by rotating the screw rod 9 to position or release the slide plate 8, thereby facilitating the installation or removal of the ear plate 5, and providing convenience for the disassembly, maintenance or cleaning of the frame 4.

[0036] See also Figure 5 The outer circumference of the screw rod 9 is fixedly sleeved with a limit ring 12, and the outer circumference of the limit ring 12 is rotatably connected to the inside of the ear plate 5 to limit the screw rod 9, prevent the screw rod 9 from sliding and deviating, and increase the stability of the screw rod 9 movement.

[0037] See also Figure 5 The outer circumferential surface of the positioning rod 10 is fixedly connected to the limiting block 13, and the outer surface of the limiting block 13 is slidably connected to the ear plate 5 through the empty groove opened inside the ear plate 5, thereby limiting the positioning rod 10, preventing the positioning rod 10 from rotating with the screw rod 9, and prompting the positioning rod 10 to always perform longitudinal lifting and lowering.

[0038] See also Figure 4 , Figure 5 and Figure 6 The outer surface of each ear plate 5 is fixedly connected to a fixing seat 14, and a sliding rod 15 is slidably inserted inside the fixing seat 14. The outer surface of the sliding rod 15 is fixedly connected to the outer surface of the slide plate 8, and the outer surface of the slide plate 8 is fixedly connected to a second spring 16. The other end of the second spring 16 is fixedly connected to the inner wall of the fixing seat 14. The second spring 16 applies a thrust to the slide plate 8, so that the slide plate 8 can automatically move back, and then the ear plate 5 is automatically positioned when the ear plate 5 is installed.

[0040] See also Figure 1 and Figure 2 A hydraulic cylinder 18 is fixedly connected to the interior of the rear end mounting plate 2, and a clamping plate 19 is fixedly connected to the output end of the hydraulic cylinder 18. The interior of the clamping plate 19 is slidably connected to the outer circumferential surface of the guide rod 3. The hydraulic cylinder 18 drives the clamping plate 19 to apply pressure to the frame 4, so that the frame 4 can be clamped as a whole.

[0041] A plate and frame filter device in the present embodiment drives the positioning rod 10 to rise and fall by rotating the screw rod 9, so that the positioning rod 10 can move into or out of the positioning hole 11, and then move the slide plate 8, so as to facilitate the disassembly, cleaning or maintenance of the frame 4 and the ear plate 5, improve the cleaning or maintenance efficiency of the frame 4, and also improve the flexibility and practicality of the filter device, thereby solving the problem that the existing plate and frame filter device is not convenient for disassembly, maintenance or cleaning of the plate frame, and the slag removal or maintenance will be restricted by the position of the plate frame, affecting the cleaning or maintenance efficiency.

[0042] It should be noted that a hand wheel is provided on the outer circumferential surface of the screw rod 9, and the screw rod 9 can be rotated and controlled by the hand wheel.

[0043] The working principle of the above embodiment is:

[0044] When it is necessary to clean or maintain the frame 4, the hydraulic cylinder 18 is started to drive the clamping plate 19 to move through the output end, so that the clamping plate 19 no longer presses the frame 4, and then the first spring 6 will apply a thrust to the adjacent ear plate 5, so that the adjacent frame 4 is automatically separated. When it is necessary to clean or maintain one of the frames 4, the two corresponding screw rods 9 are rotated in turn, and the screw rod 9 drives the positioning rod 10 to move downward, so that the positioning rod 10 moves out of the positioning hole 11, and then the slide bar 15 is pulled at the same time to drive the slide plate 8 to move out of the slide groove 7, canceling the positioning restriction on the ear plate 5, and then the upper The ear plate 5 and the frame 4 can be removed. When the frame 4 needs to be installed after cleaning and maintenance, the two ear plates 5 of the frame 4 are placed on the two guide rods 3 respectively, and then the frame 4 is pressed down. The slide plate 8 will automatically move outward under the action of the curved surface of the guide rod 3 and squeeze the second spring 16. When the ear plate 5 is completely pressed down onto the guide rod 3, the second spring 16 will push the slide plate 8 to automatically move back, prompting the slide plate 8 to insert into the slide groove 7, automatically restricting the ear plate 5, and finally rotating the screw rod 9 to drive the positioning rod 10 to move upward, so that the positioning rod 10 is inserted into the positioning hole 11, and the slide plate 8 is completely positioned.
