Description

Continuous plate pulling mechanism of filter press Technical Field The utility model relates to the field of filter presses, in particular to a continuous plate pulling mechanism of a filter press. Background Through searching for a patent document with the bulletin number of CN219662967U, the patent document drives the pulling plate trolley to move to pull the filter plate through a chain transmission system, when a plate taking claw of the pulling plate trolley touches a filter plate handle, the hydraulic motor reverses, the chain transmission system drives the pulling plate trolley to retract, when the pulling plate claw retreats, the filter plate handle is pushed to retract by the pulling plate claw, when the filter plate touches a compacting plate, the filtering plate is stopped to retract, the rear end of the plate taking claw is pressed down by the compacting plate, the front end of the plate taking claw is separated from the filter plate handle which is just pulled back, and the pulling plate trolley continues to pull the filter plate, so the repeated actions are performed until the filter plate is pulled; This patent document drives the arm-tie dolly and pulls open the filter plate back one by one at chain drive system, because the filter cake has viscidity, and the filter cake can not drop from the filter plate completely, and part filter cake still glues and hangs on the filter cloth, needs additionally to carry out the manual work and shovels, and troublesome operation, the clearance speed is slow.
