[0002] A diaphragm filter press is a filter press in which an elastic membrane is installed between the filter plates and the filter cloth. During use, after feeding is completed, a high-pressure fluid or gas medium can be injected into the diaphragm plate. At this time, the entire diaphragm will bulge and compress the filter cake, thereby achieving further dewatering of the filter cake. However, the existing device has certain problems in use and still needs continuous improvement.

[0003] A search revealed that patent publication number CN219128403U discloses a cleaning device for a diaphragm filter press, including a support frame. Multiple moving mechanisms are fixedly installed at the bottom of the support frame, and a drive frame is fixedly connected to the top of the support frame. Two reciprocating screws are rotatably connected between the drive frame and the support frame. Lifting plates are threaded onto the two reciprocating screws, and lifting rods are fixedly connected to the bottom surface of the lifting plates. The bottom ends of the two lifting rods are movably sleeved into the inner cavity of the support frame and fixedly connected to a rotating frame. A second motor drives a cleaning brush roller to rotate, while a first motor drives the reciprocating screws to rotate. The cooperation between the reciprocating screws and the lifting plates causes the lifting plates and the rotating cleaning brush roller to move up and down. The downwardly moving cleaning brush roller cleans the residual sludge on the filter membranes of the two filter plates on the diaphragm filter press. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When the device is in use, the cleaning brush roller cleans the residual sludge on the filter membrane of the two filter plates on the diaphragm filter press. However, the cleaning brush roller is inconvenient to pass between the two rotating frames, which makes it inconvenient to regularly disassemble and replace the cleaning brush roller or clean the disassembled cleaning brush roller, making the device somewhat inconvenient to use.

[0005] Therefore, a diaphragm filter press cleaning device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a diaphragm filter press cleaning device to solve the problems mentioned in the background art.

[0023] In use, the device can first be rotated by adjusting the knob at one end of the lead screw 10. Then, the rotating lead screw 10 drives the moving block 9 to move the moving seat 8 and the rotating rod 12 and the insertion hole 15 of the first insertion rod 13 at the end away from the connecting shaft 14, thereby releasing the restriction on the cleaning brush roller 16. This makes it convenient to disassemble, replace or clean the cleaning brush roller 16. The design of this structure makes it easy to quickly and conveniently disassemble, replace or clean the cleaning brush roller 16 in the later stage, improving the practicality of the device.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, two reciprocating threaded rods 3 are symmetrically rotatably connected to the drive frame 1, and two servo motors are bolted to the top of the drive frame 1. The output ends of the two servo motors are respectively connected to one end of the two reciprocating threaded rods 3, and the reciprocating threaded rods 3 are driven by the servo motors. Then, a lifting seat 4 is fitted on the outside of the two reciprocating threaded rods 3. A connecting rod 5 is welded to the bottom wall of the lifting seat 4. Finally, the bottom end of the connecting rod 5 passes through the top wall of the support frame 2 and is fixedly connected to the connecting seat 6. Furthermore, the reciprocating threaded rods 3 are driven by the servo motors, and then the rotating reciprocating threaded rods 3 drive the lifting seat 4 and the connecting rod 5 to adjust their height. Then, the lifting and adjusting connecting rod 5 drives the connecting seat 6 and the two cleaning brush rollers 16 set on the connecting seat 6 to move up and down, so that the two cleaning brush rollers 16 moving up and down clean the residual sludge on the filter membrane of the two filter plates on the diaphragm filter press.

[0027] In a preferred embodiment, two base plates 22 are symmetrically welded to the bottom wall of the support frame 2. Two casters are then installed on the bottom walls of both base plates 22, and two water spray pipes 21 are symmetrically installed on the connecting seat 6. One end of each water spray pipe 21 is connected to a rubber hose 20, and each water spray pipe 21 has spray holes on its surface. A water tank 18 is installed on one of the base plates 22, and a three-way pipe 19 is installed at the top of the water tank 18. Both ends of the three-way pipe 19 are connected to one end of each of the two rubber hoses 20. Finally, a water pump is installed on the top wall inside the water tank 18, and the output end of the water pump is connected to the three-way pipe 19. In use, the water in the water tank 18 is pumped out by the water pump, and then transported to the water spray pipes 21 through the three-way pipe 19 and the rubber hoses 20. The water is then sprayed out through the spray holes on the surface of the water spray pipes 21 to rinse the filter membranes on the two filter plates of the diaphragm filter press.

[0028] The working process of this utility model is as follows: First, the reciprocating threaded rod 3 is driven by a servo motor. Then, the lifting seat 4 and the connecting rod 5 are adjusted by the rotating reciprocating threaded rod 3. Then, the connecting rod 5 is adjusted by the lifting to drive the connecting seat 6 and the two cleaning brush rollers 16 set on the connecting seat 6 to move up and down. This allows the two cleaning brush rollers 16 to clean the residual sludge on the filter membrane of the two filter plates on the diaphragm filter press. At the same time, the water pump draws water out of the water tank 18 and transports it to the spray pipe 21 through the three-way pipe 19 and the rubber hose 20. Then, the water is sprayed out through the spray holes on the surface of the spray pipe 21 to rinse the filter membrane of the two filter plates on the diaphragm filter press.

[0029] When it is necessary to disassemble, clean, or replace the cleaning brush roller 16, the screw 10 can be rotated by adjusting the knob at one end of the screw 10. Then, the rotating screw 10 drives the moving block 9 to move the moving seat 8 and the rotating rod 12 and the insertion hole 15 of the first insertion rod 13 at the end away from the connecting shaft 14, thereby releasing the restriction on the cleaning brush roller 16, so as to facilitate the disassembly, replacement, or cleaning of the cleaning brush roller 16. The above is the working principle of this diaphragm filter press cleaning device.
