Abstract

The invention relates to the field of discharging mechanisms, in particular to a rapid discharging mechanism and a plate-and-frame filter press. The inner side wall of the hooking end of the connecting hook is arranged on the other separating shaft of the two adjacent separating shafts in a sliding way. The separation and the closure of all the filter press plates can be realized in the one-time unidirectional (separation direction or closing direction) movement process of the opening and closing mechanism by the limitation of the connecting hooks. Therefore, the time wasted by the back and forth of the opening and closing mechanism is reduced, so that the working efficiency can be greatly improved. Meanwhile, the round trip times of the opening and closing mechanism are reduced, so that the abrasion of parts in the opening and closing mechanism can be reduced, and the service life of the equipment is prolonged.

Description

Quick discharge mechanism and plate-and-frame filter press Technical Field The invention relates to the field of discharging mechanisms, in particular to a rapid discharging mechanism and a plate-and-frame filter press. Background The plate-and-frame filter press is a common solid-liquid separation device in chemical production, under the action of pressure, solid and liquid are separated by utilizing a filter frame and a filter plate, filtrate is generally discharged in a hidden-flow drainage mode, and then a filter-pressed material falls off from the filter plate and enters a receiving device, and then enters the next working procedure after being collected by the receiving device. The prior art plate and frame filter press pulls the filter plates one by one through a plate pulling manipulator to discharge, and after the discharge is completed, the filter plates are pulled back to the preset positions one by one so as to carry out the next filter pressing operation. Because the filter plates in the filter press are numerous, the existing mode of unloading through pulling the filter plates one by one can lead to the increase of unloading period, seriously influences work efficiency. And in one discharging operation, the manipulator driving the filter plate to move can perform multiple reciprocating motions.
