The operating control valve is arranged to move to the left side, the high-pressure emulsion moves the two-position two-way valve to the left, the liquid inlet of the filter is stopped, the hydraulic control one-way valve is opened simultaneously, the liquid inlet side of the filter is communicated with the sewage discharge outlet, the high-pressure emulsion flows to the liquid outlet side of the filter through the bypass valve, flows to the hydraulic control one-way valve after passing through the filter screen and is discharged through the backflushing sewage discharge outlet, and therefore the filter screen of the filter is cleaned. After the filter screen of the filter is cleaned, the control valve is moved back to the middle position, and the filtering station supplies liquid normally.
3. When the filter screen is blocked by impurities, the filter screen is not cleaned by back flushing in time, and when the pressure difference between an inlet and an outlet is more than 0.35Mpa, the bypass valve is opened to ensure that the system keeps supplying liquid.
The further preferred technical scheme is as follows:
the liquid inlet is communicated with the emulsion pump station through a high-pressure rubber pipe, the liquid outlet is communicated with a hydraulic device of the hydraulic support through the high-pressure rubber pipe, and the liquid inlet and the liquid outlet both adopt DN32 standard joints.
Through setting up the high-pressure rubber tube, make things convenient for the setting and the connection of the pipeline of business turn over liquid, inlet, liquid outlet all adopt DN32 standard joint, further make things convenient for being connected of opening and high-pressure rubber tube.
The pipeline of the liquid inlet is provided with a pressure gauge.
Through setting up the manometer, be convenient for monitor the pressure of the confession liquid of inlet department.
The pipeline connection between the liquid inlet and the liquid outlet is through a quick connector.
Through setting up quick-operation joint, make things convenient for the connection of part and pipeline.
The backflushing sewage draining outlet is communicated with the liquid drainage buffer tank.
Through setting up the flowing back baffle-box, conveniently wash the discharge of waste liquid.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-3, a single-cylinder high-pressure emulsion backwash filter station is composed of a filter, an operating valve 4 and a connecting pipeline; the filter is provided with a filter screen 1, one liquid inlet side of the filter is communicated with a liquid inlet 7 through a two-position two-way valve 2, one liquid outlet side of the filter is communicated with a hydraulic device of the hydraulic support through a liquid outlet 8, and the liquid outlet 8 is communicated with the liquid inlet 7 through a bypass valve 5; one side of the filter for liquid inlet is communicated with a backflushing sewage outlet 6 through a hydraulic control one-way valve 3; the connecting port of the two-position two-way valve 2 is communicated with the liquid inlet through an operating valve 4, and the operating valve 4 is connected with and controls the two-position two-way valve 2.
The liquid inlet 7 is communicated with an emulsion pump station through a high-pressure rubber tube, the liquid outlet 8 is communicated with a hydraulic device of a hydraulic support through the high-pressure rubber tube, and the liquid inlet 7 and the liquid outlet 8 both adopt DN32 standard joints.
Through setting up the high-pressure rubber tube, make things convenient for the setting and the connection of the pipeline of business turn over liquid, inlet 7, liquid outlet 8 all adopt DN32 standard to connect, further make things convenient for being connected of opening and high-pressure rubber tube.
