Description

TECHNICAL FIELD

[0001] The utility model relates to filter press technical field, concretely is a kind of filter cloth cleaning device of filter press. BACKGROUND

[0002] In the production process of nickel carbonate, filter press is widely used in solid-liquid separation to separate solid precipitate and liquid solution from reaction mixture. Because a large amount of solid particles and suspended solids are produced in the production process of nickel carbonate, the filter cloth is easily contaminated, resulting in reduced filtration efficiency. With the passage of time, dirt on the filter cloth will continue to accumulate, seriously affecting its filtering function, and thus affecting production efficiency and product quality. Therefore, the filter cloth needs to be cleaned in time to maintain its good working condition, which requires the use of efficient filter cloth cleaning device.

[0003] The patent with publication number CN220633167U discloses a filter cloth cleaning device of filter press, which includes a cleaning tank, a control panel fixedly installed on the outer surface of the cleaning tank, a support frame fixedly installed on the top of the cleaning tank, a winding roller movably installed on the outer surface of the support frame, and a functional structure fixedly installed on the left outer surface of the cleaning tank. When in use, the worker first winds the filter cloth of the filter press to be cleaned around the guide roller, so that the filter cloth body is in a U-shaped state inside the liquid storage tank, and the end of the filter cloth is connected to the winding roller, so that the filter cloth can be wound. By turning on the ultrasonic atomizing sheet, the cleaning liquid is in an atomized state, and the filter cloth in the liquid storage tank can be evenly covered with the cleaning liquid, thereby eliminating the need for spraying and liquid spraying. By starting the driving motor to drive the half gear to rotate, the outer surface of the half gear is engaged with the outer surface of the gear plate, thereby achieving the effect of moving the gear plate.

[0004] However, the existing technology has some shortcomings in actual use. When the filter cloth passes through the main extrusion roller and the auxiliary extrusion roller, the functional motor is used to drive the main extrusion roller and the driven gear to rotate first, the driven gear cooperates with the driving gear to realize the synchronous rotation of the auxiliary extrusion roller, and then the filter cloth body is extruded to squeeze out the excess water in the filter cloth body. However, in this process, the water extruded by the main extrusion roller and the auxiliary extrusion roller will adhere to the surface of the main extrusion roller and the auxiliary extrusion roller, and will drop in large quantities into the functional box, and finally flow from the top of the cleaning tank to the ground, causing the working environment to be humid. Secondly, since the winding roller is located below the main extrusion roller and the auxiliary extrusion roller, the water adhering to the main extrusion roller and the auxiliary extrusion roller will flow downward along the filter cloth body, causing the filter cloth body after extrusion and drainage to be wet again, and finally the filter cloth body wound by the winding roller is in a wet state, which requires additional drying treatment, causing unnecessary trouble and waste of resources. Therefore, in order to improve this situation, we propose a filter cloth cleaning device of filter press to improve the cleaning effect. SUMMARY
