High water base filtration system back washing apparatus based on fluid-solid coupling vibration, and back washing method thereof

Abstract

The invention belongs to the technical field of coal mine fully-mechanized mining work surface filters, and provides a high water base filtration system back washing apparatus based on fluid-solid coupling vibration, and a back washing method thereof. The high water base filtration system back washing apparatus comprises a filtration core arranged in a filter, a jet flow liquid storage chamber, a drainage member, a clockwise jet flow pipe and a counterclockwise jet flow pipe, wherein a flow meter and a throttle valve are arranged between a high water base hydraulic pump and the first channel of the drainage member, the second channel of the drainage member is communicated to the liquid inlet P of an insertion-installation valve through the jet flow liquid storage chamber, the liquid outlet A and the liquid outlet B of the insertion-installation valve are respectively communicated to the clockwise jet flow pipe and the counterclockwise jet flow pipe, the clockwise jet flow pipe and the counterclockwise jet flow pipe are respectively provided with a plurality of clockwise jet flow holes and counterclockwise jet flow holes obliquely intersecting with the cross section circumference of the filtration core, and the control ends of the insertion-installation valve and the throttle valve, and the output end of the flow meter are connected to a PLC controller. According to the present invention, with the apparatus and the method, the back washing effect is improved, the back washing control process is simple, and the apparatus and the method can be widely used in coal mine fully-mechanized mining work surface.

Description

technical field [0001] The invention belongs to the technical field of hydraulic support filters, and in particular relates to a backwashing device and method for a high water-based filter system based on fluid-solid coupling vibration. Background technique [0002] With the continuous improvement of fully mechanized mining technology in coal mines, the requirements for the use of high water-based hydraulic oil in underground hydraulic supports are getting higher and higher, and the working environment in underground mines is harsh. During the use of hydraulic support filters, the filter element needs to be backwashed. In order to ensure the normal work of each actuator of the hydraulic support. [0003] The backwash filter in the existing hydraulic support mainly adopts manual backwash, which is inconvenient for workers to operate underground, which increases the labor intensity of workers, and most of the existing filters do not have pressure monitoring devices, the best t...

Problems solved by technology

[0003] The backwash filter in the existing hydraulic support mainly adopts manual backwash, which is inconvenient for workers to operate underground, which increases the labor intensity of workers, and most of the existing filters do not have pressure monitoring devices, the best time to open the filter backwash Difficult to determine, when manual operation is required, there are often more impurities on the filter element, which affects the service life of the filter and the reliability of the equipment; most of the existing filter backwashing methods are reverse flow through high water-based hydraulic oil To clean the impurities on the filter element, the backwash action takes a long time, and the flushing effect is not good

The existing filter with a rotatable filter element is driven by an external motor, which will increase the volume of the equipment, which is not convenient for installation and maintenance of the equipment and does not meet the explosion-proof working conditions in coal mines
