Description

Technical Field

[0001] This utility model belongs to the field of filter press cleaning technology, and in particular, a cleaning device for filter presses. Background Technology

[0002] Filter presses are widely used in many fields such as chemical, food, and environmental protection. Their working principle is to use pressure to force liquids out of the material through filter cloth, while solids are retained on the cloth. During the use of a filter press, a large amount of solid impurities and stains accumulate on the filter cloth. If not cleaned promptly, this will not only affect the filtration efficiency and lifespan of the filter cloth but also lead to a decline in the filter press's performance. Existing filter press cleaning devices generally use a single water spray cleaning method. When the vibration of the cleaning device is weak, the impact force of the water flow on the stains on the filter cloth surface is insufficient, failing to effectively break the adhesion between the stains and the filter cloth fibers. This results in numerous cleaning blind spots, reducing the comprehensiveness and uniformity of the cleaning process.

[0003] A search revealed Chinese patent document (authorization announcement number CN203936053U), indicating that this utility model relates to a bottom cleaning device for a filter press, comprising a longitudinal platform, a transverse platform, and a cleaning device. The longitudinal platform is mounted on two parallel guide rails of the filter press in a sliding state, the transverse platform is mounted on the top surface of the longitudinal platform in a sliding state, and the cleaning device is mounted on the top surface of the transverse platform. A first motor and a drive shaft drive the longitudinal platform to achieve longitudinal movement of the cleaning device. Once the cleaning device is moved to the filter plate position, a second motor, through a double-headed screw and nut, achieves transverse movement of the cleaning device. A third motor drives a swing cleaning rod to rotate and clean, providing comprehensive and repeated cleaning of the filter cloth. This device offers high cleaning efficiency, simplifies the cleaning process, and provides comprehensive cleaning. However, when the device's vibration capability is weak, the water flow's impact on the surface dirt of the filter cloth is insufficient, failing to effectively break the adhesion between the dirt and the filter cloth fibers, resulting in numerous cleaning blind spots and reducing the comprehensiveness and uniformity of the cleaning process.

[0026] like Figures 1 to 5The cleaning device for a filter press shown includes a frame 1 that provides an installation platform and stable support for other components. The frame 1 is mainly composed of a thrust plate, a clamping plate, a crossbeam, and a support column. The thrust plate is fixed at one end of the frame to bear the pressure during the filtration process and to provide a positioning reference for the filter plate frame 104. The clamping plate can move on the crossbeam and clamps the filter plate frame 104 through a clamping mechanism to ensure the sealing of the filter chamber during the filtration process. The crossbeam and the support column are connected to each other to form a stable frame structure, which bears various loads during the operation of the filter press and prevents the frame from deforming and affecting the filtration effect. A motor 2 is installed on the side of the frame 1. The output shaft of the motor 2 is connected to a threaded rod 201 through a coupling. A threaded block 204 is connected to the outer periphery of the threaded rod 201.

Vibration blocks 304 for vibration are installed on the outer periphery of the circular limiting plates 303. A guide block 202 is installed on the top of the threaded block 204. A guide rod 203 is welded inside the frame 1. 03 completely penetrates the interior of the guide block 202, and the motor 2 is turned on. The motor 2 drives the threaded block 204 and the guide block 202 to move along the direction of the guide rod 203. The threaded block 204 drives the hollow column 3 and the vibrating block 304 to move in the horizontal direction. The first spring 206 drives the first limiting plate 207 to move towards the hanging ear 105. The vibrating block 304 contacts the hanging ear 105. During the movement, the vibrating block 304 continuously impacts the hanging ear 105, causing the hanging ear 105 to vibrate. Impurities on the hanging ear 105 are shaken off, increasing cleaning efficiency.

[0028] The threaded block 204 is internally connected to a first spring 206. One end of the first spring 206 is connected to a first limiting plate 207.
