Description

Technical Field

[0001] The present invention belongs to the field of filter presses, and specifically relates to a rack-type filter cloth cleaning lifting device for a filter press and a method for using the same. Background Art

[0002] The filter press is a filtering equipment in the solid-liquid separation industry. The material enters the filter press through the pressure of the feed pump, and the particles in the filtrate are intercepted by the filter medium filter cloth to form a filter cake in the filter chamber. The filtrate is discharged from the discharge holes of the filter plate. During long-term use, the particles in the material will adhere to the filter cloth. As the particles accumulate, they will block the air holes of the filter cloth, making it difficult to discharge the filtrate and unable to form a filter cake, affecting normal production. For this reason, a filter cloth cleaning device is required.

[0003] The applicant's invention patent "Filter cloth cleaning lifting device for filter press" (authorization announcement number: CN 202161851 U) and the applicant's invention patent "Bottom-type filter cloth cleaning device for filter press" (authorization announcement number: CN 212039185 U) disclose a filter cloth cleaning lifting device for filter press. Most of the filter cloth cleaning devices currently used are based on these two patents, but there are shortcomings: the filter cloth cleaning lifting device requires a tall cleaning frame, and a power device is arranged on the top of the frame. The filter cloth cleaning lifting device of this structure has a complex structure and high manufacturing cost. In addition, the installation position of the filter cloth cleaning device is too high, which is inconvenient to install and debug and highly dangerous. Summary of the invention

When the water washing pipe reciprocates up and down, the cleaning transverse pipe sprays water to clean both sides of the filter plate; the descent termination position of the water washing pipe is determined by the cooperation of a descent position proximity switch and a descent position sensing plate; the ascent termination position of the water washing pipe is determined by the cooperation of an ascent position proximity switch and an ascent position sensing plate.

[0008] The present invention provides a method for using a rack-type filter cloth cleaning lifting device for a filter press, and the steps are as follows: Step 1: Start the driving device, the driving gear rotates to drive the two water washing pipes to descend vertically along the guide sleeve.
