This study focuses on the maintenance of grinding fluid.During the processing,a large amount of solid particles mix into the fluid.The existing equipment has low dross removal efficiency,leading to frequent replacement of the grinding fluid,which increases the production cost for enterprises.By analyzing the filtering equipment,a new type of filter screen can be used to intercept solid particles in the liquid,a specific mechanical structure can be used to achieve the reuse of filter screen and the rapid drainage of solid particles,and related electrical and programmed automation can be added to achieve automatic operation of the equipment.experimental verification proves that this equipment can efficiently filter out impurities in the grinding fluid,extend the service life of the grinding fluid,thereby reducing the production costs of enterprises while increasing their competitiveness.
