Description

A filter cake crushing device for filter press

Technical Field

The utility model relates to the technical field of crushing equipment, in particular to a filter cake crushing device for a filter press.

Background Art

Filter press is often used in sludge recovery and treatment operations. It is a mechanical device that uses mechanical force on one side of the filter medium to achieve solid-liquid separation of sludge. In order to facilitate the treatment of the mud cake produced by the filter press, it is usually crushed first using a crushing device.

The existing filter press filter cake crushing device is mostly a horizontal or vertical crushing roller, which crushes the filter cake through the operation of a motor. However, the filter cake has a certain volume and will drop rapidly due to gravity, resulting in uneven stirring. It is difficult to crush the filter cake completely by simple stirring and crushing.

After searching, a Chinese patent with application number CN202121480964.2 discloses a filter press mud cake rapid crushing device. By setting a crushing roller at the feed inlet, it can not only prevent the mud cake from clogging the feed hopper, but also roughly crush the mud cake entering the device, and then cooperate with the crushing roller to thoroughly crush the mud cake to improve the crushing efficiency. However, the direction of two of the stirrings is vertical rotation stirring, which will accelerate the falling of the mud cake and make the stirring and crushing incomplete. Moreover, since the filter cake is not completely dry, the filter cakes after coarse crushing stick to each other, resulting in unsatisfactory stirring effect. The stickiness of the particles after stirring will also slow down the discharge speed below, affecting the efficiency of the entire stirring.
