[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-5The illustrated filter plate cleaning device for a filter press includes a movable mounting frame 1, which is slidably mounted on the filter press. The mounting method is prior art and will not be described in detail. A hydraulic cylinder 2 is connected to the top of the movable mounting frame 1, and a connecting rod 3 is connected to the top of the hydraulic cylinder 2. A strip-shaped opening corresponding to the connecting rod 3 is opened on the side wall of the movable mounting frame 1. A U-shaped frame 4 is connected to the side wall of the connecting rod 3. A motor 5 is connected to the top of the U-shaped frame 4. A lead screw 6 is connected to the output end of the motor 5. A threaded cylinder 7 is connected to the outer wall of the lead screw 6. The bottom of the threaded cylinder 7 is connected to… A U-shaped cleaning frame 8 is connected to the front and rear inner walls of the U-shaped cleaning frame 8. A cleaning pad is provided on the front side of each cleaning block 9. Moving blocks 10 are provided on both the left and right sides of the U-shaped cleaning frame 8. First sliders 11 are connected to both the left and right sides of the U-shaped cleaning frame 8. A first groove corresponding to the first slider 11 is opened on the side wall of the moving block 10. A spring 12 is connected to the bottom of the first slider 11, and the other end of the spring 12 is connected to the bottom of the first groove. Push rods 13 are connected to both the front and rear sides of the moving block 10. A fixing frame 14 is connected to the side wall of the vertical part of the U-shaped frame 4. An internally connected tilting frame 15 is connected to a push rod 13 via a rotating shaft. A positioning plate 16 is connected to the other end of the tilting frame 15. A hydraulic cylinder 2 pulls a connecting rod 3, which in turn pulls a U-shaped frame 4. The U-shaped frame 4 causes the U-shaped cleaning frame 8 and the moving block 10 to move downwards, positioning the two positioning plates 16 on the front and rear sides of the filter plate. A motor 5 drives a lead screw 6 to rotate, which in turn causes a threaded cylinder 7 to move downwards. The threaded cylinder 7 pushes the U-shaped cleaning frame 8, which in turn pulls the moving block 10 downwards via a first slider 11 and a spring 12. When moving downwards, push the push rod 13, which drives the flipping frame 15 to rotate. The flipping frame 15 pushes the positioning plate 16, which can be used to position the filter plate to be cleaned using the positioning plates 16 on both the front and rear sides. This avoids the inconvenience of needing to precisely position the filter plate. After positioning is completed, continue to push the U-shaped cleaning frame 8 downwards. Since the positioning plate 16 has already positioned the filter plate, the moving block 10 is limited, which causes the U-shaped cleaning frame 8 to move downwards and compress the spring 12. The U-shaped cleaning frame 8 pulls the cleaning block 9, which can be used to clean the surface of the filter plate.

[0020] The top of the U-shaped cleaning frame 8 is connected to a water inlet pipe 17, and the bottom of the water inlet pipe 17 is connected to two water supply pipes 18. The other ends of the two water supply pipes 18 are respectively connected to the top of the two cleaning blocks 9. Water outlet holes are opened on the opposite side of the two cleaning blocks 9. The cleaning water is introduced into the water inlet pipe 17 and then enters the two water supply pipes 18 through the water inlet pipe 17. The water is then sprayed out through the water outlet holes on the cleaning blocks 9 to rinse the surface of the filter plate.

[0021] The side wall of the movable block 10 is connected to the second slider 19, and the side wall of the U-shaped frame 4 is provided with a second sliding groove corresponding to the second slider 19, which can conveniently limit the movable block 10, thereby limiting the U-shaped cleaning frame 8.

[0022] A protective cover 20 is provided on the outside of the motor 5. The bottom of the protective cover 20 is connected to the top of the U-shaped frame 4, which can easily protect the motor 5.

[0023] Working principle of this utility model:

[0024] By using hydraulic cylinder 2 to pull connecting rod 3, connecting rod 3 pulls U-shaped frame 4, U-shaped cleaning frame 8 and moving block 10 downwards, so that the two positioning plates 16 are positioned on the front and rear sides of the filter plate. By using motor 5 to drive lead screw 6 to rotate, lead screw 6 drives threaded cylinder 7 to move downwards, threaded cylinder 7 pushes U-shaped cleaning frame 8, U-shaped cleaning frame 8 pulls moving block 10 downwards through first slider 11 and spring 12, moving block 10 pushes push rod 13 when moving downwards, push rod 13 drives tilting frame 15 to rotate, tilting frame 15 pushes positioning plates 16, thus utilizing the positioning plates on the front and rear sides. Plate 16 positions the filter plate that needs to be cleaned, avoiding the inconvenience of precise positioning of the filter plate. After positioning, the U-shaped cleaning frame 8 is pushed downward. Since the positioning plate 16 has positioned the filter plate, the moving block 10 is limited, causing the U-shaped cleaning frame 8 to move downward and compress the spring 12. The U-shaped cleaning frame 8 pulls the cleaning block 9, which can be used to clean the surface of the filter plate. The cleaning water is introduced into the water inlet pipe 17 and enters the two water supply pipes 18 through the water inlet pipe 17. The water is then sprayed out through the water outlet on the cleaning block 9 to rinse the surface of the filter plate.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
