Detailed Description

The actuating mechanism is applied to a plate type filter with reference to the attached drawings of the specification and the figure 1. The filter is provided with a plurality of filter plates 7, and the outer side surfaces of the filter plates 7 are sleeved with filter bags. After the fluid flows through the filter plates 7, solid particles in the fluid are trapped by the filter bags, after the fluid is filtered for a period of time, the filter plates 7 are pressed towards one side by a screw-type or hydraulic cylinder-type pressing mechanism on the filter, so that the filter bags are squeezed to be dry, the filter bags are taken down and shaken, and the trapped solid powder is shaken off.

The actuating mechanism is used for pushing the filter plates 7 on the filter so as to lead the filter plates 7 to be gathered together firstly. After the extrusion is completed, the actuator needs to push the filter plate 7 away in the opposite direction, so as to take out the cloth bag from the filter plate 7, or take out the filter plate 7 from the machine body 1 for cleaning.
