Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a filter press with a cleaning structure. Background Technology

[0002] A filter press is a solid-liquid separation device that uses a special filter medium to apply pressure to the material being filtered, causing the liquid in the material to be extracted. Filter presses are widely used in industries such as chemical, pharmaceutical, metallurgical, dye, and ceramics.

[0003] Chinese Patent Publication No. CN214680522U discloses a diaphragm-controlled filter press, belonging to the field of diaphragm filter presses. It includes a base, with a support plate fixedly connected to the upper surface of the base. The diaphragm-controlled filter press is fixedly connected to the upper surface of the support plate. A liquid outlet hood is fixedly connected to the bottom surface of the diaphragm-controlled filter press. Two sets of symmetrical support columns are fixedly connected to the upper surface of the base, and a filter box is fixedly connected to the top of both sets of support columns. A leakage port is provided on the bottom surface of the filter box. By using the liquid outlet hood in conjunction with the liquid inlet hood, water squeezed out by the diaphragm-controlled filter press can be sent from the diaphragm-controlled filter press into the interior of the filter box, preventing splashing of waste liquid during outflow, thus avoiding unnecessary waste and environmental pollution. By using a filter plate in conjunction with the filter box, the waste liquid entering the filter box can be filtered, removing residual materials from the waste liquid and preventing a large amount of material from flowing out with the liquid, thus avoiding unnecessary resource waste.

[0004] The existing technical solutions mentioned above have the following drawbacks: they lack a cleaning structure, the filter cloth needs to be removed when cleaning, which is cumbersome and wasteful of manpower and resources, and the filtration efficiency is low. Therefore, this utility model provides a filter press with a cleaning structure to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter press with a cleaning structure, comprising:

[0007] The workbench has a filter box at its upper end and an observation window at the front end of the filter box. The workbench has a filter residue outlet inside and a solenoid valve is installed on the outside of the filter residue outlet. The left end of the filter box is connected to a feed pipe and a pressure pump is installed on the outside of the feed pipe. The right end of the filter box is connected to a discharge pipe and a filter cloth is installed inside the filter box.

[0008] The motor is located inside the upper side of the filter housing, and a drive gear is connected to the upper end of the motor. A driven gear is connected to the outer end of the drive gear, and a transmission connecting block is installed inside the driven gear. A threaded screw is connected inside the transmission connecting block, and a limit block is connected to the outer end of the transmission connecting block. A connecting plate is connected to the upper end of the threaded screw, and a cleaning component is installed at the lower end of the threaded screw. A limit rod is connected to the upper end of the cleaning component and is located outside the threaded screw.

[0009] Preferably, the longitudinal cross-sectional shape of the feed pipe, the discharge pipe and the filter residue outlet is U-shaped.

[0010] Preferably, the lead screw is symmetrically arranged about the center line of the drive gear, and the threads on the lead screw have opposite directions of rotation.

[0011] Preferably, the cleaning assembly consists of a mounting block, a cleaning brush, and a sealing plate;

[0012] The mounting block is connected to the lower end of the threaded screw;

[0013] The cleaning brush is attached to the inner end of the mounting block;

[0014] A sealing plate is attached to the lower end of the mounting block.

[0015] Preferably, the sealing plates are arranged symmetrically about the center line of the filter cloth, and the sealing plates are connected to the filter box by a snap-fit ​​method.

[0016] Preferably, the limiting block forms a sliding structure inside the filter housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the filter press with a cleaning structure solves the problems of not having a cleaning structure, having to remove the filter cloth when cleaning, which is cumbersome and complicated, wastes manpower and resources, and has low filtration efficiency.

[0018] The system is equipped with a pressure pump, a feed pipe, and a discharge pipe. The pressure pump pressurizes the liquid to be filtered and then transports it to the inside of the filter box through the feed pipe. After being filtered by the filter cloth, it is output from the discharge pipe. The filter residue remains on the filter cloth and is discharged from the filter residue outlet after cleaning. The system is simple in structure and easy to operate.

[0019] The system is equipped with a motor, which drives the drive gear to rotate, which in turn drives the transmission connecting block to rotate through the driven gear. The threaded connection between the transmission connecting block and the threaded screw, as well as the limiting sliding of the limiting block, allows the threaded screw to drive the cleaning component to move up and down. The operation is simple and the structure is stable.

[0020] By incorporating a cleaning component, a motor drives the cleaning component to move up and down, allowing the cleaning brush to clean the filter cloth. Simultaneously, a sealing plate is installed to seal the filter during the pressing process, preventing any disruption to the pressing operation and thus increasing the filter press's efficiency.

[0030] Working principle: When using a filter press with a cleaning structure, firstly, as... Figure 1 , Figure 2 and Figure 4 As shown, the liquid to be filtered is pressurized by the pressure pump 3 and then transported from the feed pipe 4 to the inside of the filter box 2. After being filtered by the filter cloth 8, it is output from the discharge pipe 5. Then, the motor 9 drives the drive gear 10 to rotate, which in turn drives the transmission connecting block 12 to rotate through the driven gear 11.
