Automatic hydraulic control system of filter press

Abstract

Disclosed is an automatic hydraulic control system of a filter press. A slideway is mounted on a seat of a filter press, a sensor is mounted at the rear end of the slideway, a slider and a magnet are mounted on the slideway, a pull rod is connected with the slider and a guide plate, the guide plate is arranged at the front end of a piston rod of a hydraulic system, a locking nut is arranged to mount the guide plate at the front end of the piston rod, a guide sleeve is mounted on the seat of the filter press, a guide rod is arranged to connect the guide sleeve with the guide plate, and a touch screen is connected with a PLC (programmable logic controller) of an electric control system which is connected with the sensor. The stroke length of the piston rod can perform program setting to signals entering the PLC through the touch screen, the guide plate mounted by the piston rod is connected with the pull rod to drive the magnet to move, and the touch screen can set and adjust the stroke of the piston rod at any time, so that multipurpose effect can be realized, and different materials can be processed only by modifying parameters.

Description

technical field [0001] The invention relates to a hydraulic automatic control system of a filter press. Background technique [0002] The filter press is the main filter equipment for solid-liquid separation. The hydraulic system is the main component installed on the filter press. When filtering materials, the hydraulic stroke of the hydraulic system compresses the filter plate to achieve solid-liquid separation. In the prior art, The hydraulic stroke of the hydraulic system is controlled by the stroke switch or the limiter. However, in field use, since the filter plate pressed by the hydraulic control system is a vulnerable part of the filter press, the vulnerable parts are often used in long-term use. If there is any damage, the components must be replaced frequently, but there is a large deviation in the thickness of the filter plate or filter cloth to be replaced, or the spare parts are not added in time, so that the stroke space of the hydraulic compression is increase...

[0002] The filter press is the main filter equipment for solid-liquid separation. The hydraulic system is the main component installed on the filter press. When filtering materials, the hydraulic stroke of the hydraulic system compresses the filter plate to achieve solid-liquid separation. In the prior art, The hydraulic stroke of the hydraulic system is controlled by the stroke switch or the limiter. However, in field use, since the filter plate pressed by the hydraulic control system is a vulnerable part of the filter press, the vulnerable parts are often used in long-term use. If there is any damage, the components must be replaced frequently, but there is a large deviation in the thickness of the filter plate or filter cloth to be replaced, or the spare parts are not added in time, so that the stroke space of the hydraulic compression is increased and the compression length is not enough. In a tight state, the position control of the travel switch and the limiter stops the hydraulic pressure, causing the material to leak from the filter plate during material filtration, resulting in the safety of the operator and affecting the filtration efficiency. loss of production
