Tightening mechanism for opening and closing filter press

Abstract

The invention relates to the field of dissociating the solid and liquid, which in detail relating to an open and close tensioning mechanism of the pressing filter. The open and close tensioning mechanism comprises: bearing plate with a fixed position, exerting plate which can move out and back in relative with the bearing plate, actuating mechanism with prime motor, and screw pair possessing bolt and cover nut and driven by the actuating mechanism. The said screw pair are installed on the two sides of the bearing plate and exerting plate in pair, the two ends of the blot are connected with the bearing plate and exerting plate respectively. The said exerting plate can be droved by the screw pair to move out and back. When starting the open and close tensioning mechanism, opening the filtering board or closing it, pressing the filtering board in the form of pulling, the bolt bearing the pull force when the filtering board is pressed. The invention is characterized by the integrating the functions of pull off the filtering board, closing the filtering board, pressing the filtering board and locking the position of the filtering board; the length of travel of the filtering board closing is large and fast; the great bearing capability of the bolt after the filtering board being pressed; and the simple and compact structure.

Description

technical field [0001] The invention relates to the field of solid-liquid separation, in particular to an opening and closing tensioning mechanism of a filter press. Background technique [0002] It is well known that the filter press needs to compress the filter plate to form a closed filter chamber for the pressure filtration of the suspension. After the filter press is finished, the filter plate needs to be pulled apart to remove the filter cake in the filter chamber. Compressing the filter plate is accomplished by a pressing mechanism, and pulling the filter plate is completed by a special pulling mechanism, or the pressing mechanism can also be used to save the complicated pulling mechanism. The pressing mechanism is composed of a pressure bearing plate fixed on the support, a pressure applying plate that can move back and forth relative to the pressure bearing plate, and a transmission device that drives the pressure applying plate to move. The main function of the t...

Problems solved by technology

The advantage of this pressing mechanism is that the filter plate can be opened and closed quickly and long-stroke, and the space occupied is reduced, but the structure and control system are complicated, resulting in increased costs and increased maintenance workload.
