Abstract

The invention relates to a cleaning method for filter cloth of a centrifugal machine, and particularly relates to a cleaning method and system for filter cloth of a centrifugal machine in wire cutting waste mortar recycling, aiming to provide a cleaning method and a cleaning system which can clean filter cloth of a scraper efficiently so as to solve the problems that in the prior art, the filter cloth of the scraper is not cleaned thoroughly, the residual impurities are high in content, and the filter cloth is required to be replaced frequently in the production process. The cleaning method comprises the following steps of (1) alkaline washing, (2) acid pickling, (3) washing, and (4) drying. The cleaning method and the cleaning system which are provided by the invention have the positive beneficial effects that the method is used for cleaning fine powder and polyethylene glycol in clearances of the filter cloth of the scraper clearly by the combined action of acid pickling, alkaline washing and ultrasonic wave, the filter cloth of the scraper can be effectively cleaned, the service life of the filter cloth is prolonged, and the cost is saved.

Description

technical field

[0001] The invention relates to a cleaning method for a filter cloth for a centrifuge, in particular to a cleaning method and a cleaning system for a centrifuge filter cloth in the recovery of wire-cut waste mortar. Background technique

[0002] Filter cloth is a filter medium woven from natural fibers or synthetic fibers. Includes metal mesh or strainer. Filter media woven from natural or synthetic fibers. Commonly used materials are cotton, hemp, wool, cocoon silk, asbestos fiber, glass fiber and some synthetic fibers.

[0003] In the field of photovoltaic production, most of the recycling of waste mortar adopts PZG horizontal scraper centrifuge. During the working process of the centrifuge, the waste mortar is filtered by scraper filter cloth. Since the silicon carbide particles are small and contain polyethylene glycol, the service life of the scraper filter cloth is short and the replacement frequency of the filter cloth is high. In addition to the pr...
