Full-automatic hydraulic plate pulling mechanism of filter press

Abstract

The invention relates to a full-automatic hydraulic plate pulling mechanism of a filter press. The full-automatic hydraulic plate pulling mechanism comprises filter press main beams, a filter plate group, a cylinder assembly bracket, a plate pulling device and a PLC control system, wherein the outer side of the main beam between the fixed end and the compressed end of the filter press is provided with a track; the main beams at the fixed end and the compressed end of the filter press are respectively provided with a driven wheel and a resetting check block; the plate pulling device is connected in the track through a chain on the driven wheel; the cylinder assembly bracket at the compressed end of the filter press is provided with a driving wheel, an oil motor and a proximity sensor; the oil motor is connected with a hydraulic station through an electromagnetic directional valve; and the proximity sensor is connected with the PLC control system. In the invention, the plate pulling device is adopted to be contacted with filter plates of the filter plate group so as to provide resistance information for the proximity sensor, and then the proximity sensor utilizes the PLC control system to control the electromagnetic directional valve to provide hydraulic power for the oil motor, thus realizing that the plate pulling device pulls the filter plates by reversing; and the full-automatic hydraulic plate pulling mechanism has compact integral structure, stable operation, long service life, high efficiency, no need of manual auxiliary operation, lower labor intensity and high automaticity, and the plate pulling device can smoothly and steadily pull the filter plates by reversing.

Description

technical field [0001] The invention relates to a plate pulling mechanism of a filter press, in particular to a fully automatic, hydraulically driven plate pulling mechanism of a filter press. Background technique [0002] The existing automatic plate pulling method of the filter press adopts the mechanical pendulum plate type and the frequency conversion variable speed method. The disadvantage is that the starting current is large when the mechanical pendulum plate type and the electric frequency conversion variable speed method are used to pull the filter plate, and the chain and sprocket slippery phenomenon is prone to occur during the process of pulling the filter plate. , the puller handles on both sides are not easy to synchronize, the instantaneous pull force is too large, the motor is burnt out due to overcurrent, the filter plate lugs are easily deformed, the cost is high, and the service life is short; and there are slippage phenomena on both sides of the puller han...
