Detailed Description

Referring to fig. 1, the mine backwashing water filter comprises a main water pipeline 10, one end of which is a water inlet end 11, and the other end of which is a water outlet end 12.

Trunk line 10 internal fixation filter screen 20, filter screen 20 are one end opening, one end confined column, and its axis and main water pipe 10 equidirectional, filter screen 20's open end 21 is established and is being intake end 11 orientation, establishes on the lateral wall of the blind end 24 department of filter screen 20 at sewage pipes 22, and sewage pipes 22 extends to the outside of main water pipe 10, and the part that extends to the main water pipe 10 outside is equipped with blowoff valve 23.

The gap between the inner wall of the main pipe 10 and the outer wall of the filter screen 20 is a transition channel 16, and the transition channel 16 is communicated with the water outlet end 12 and is not communicated with the water inlet end 11.

The filter screen 20 is internally provided with a steering valve 30, the steering valve 30 is fixed on a rotating shaft 31, two ends of the rotating shaft 31 extend outwards and are fixed on the pipe wall of the main water pipeline 10, one side of the rotating shaft 31 extends outwards continuously and is exposed outside the main water pipeline 10, and the side end part is fixed with a power component capable of driving the rotating shaft 31 to rotate.

The diverter valve 30 is plate-shaped with an outer contour matching the shape of the cross-section of the inner wall of the filter screen 20.

The whole mine backwashing water filter is divided into two sections by the steering valve 30, wherein one section is a front section 40, and the other section is a rear section 41.

In order to save power, the power component capable of driving the rotating shaft 31 to rotate is a rotating handle 32, and the hand of a person is used as a power source.

To improve efficiency, the closed end 24 is a solid material that does not allow water to pass through.

In order to monitor the blockage degree of the filter screen, pressure gauges 13 are fixed on the main water pipe 10 at the water inlet end 11 and the water outlet end 12.

The working principle is as follows:

during normal filtration, as shown in fig. 1, the blowdown valve 23 is closed, the plane where the diverter valve 30 is located is parallel to the water flow direction, water enters the filter screen 20 from the water inlet end 11 and the open end 21, then the cylindrical side surface (namely the filtering surface) of the filter screen 20 enters the transition passage 16, impurities are left on the inner wall of the cylindrical side surface (namely the filtering surface) of the filter screen 20 or temporarily stored in the filter screen 20, and the filtered water enters the water outlet end 12 from the transition passage 16 and flows out.

When in pollution discharge, as shown in fig. 2, the pollution discharge valve 23 is opened, the rotary handle 32 is rotated to enable the plane of the steering valve 30 to be vertical to the water flow direction, water enters the interior of the filter screen 20 of the front section 40 from the water inlet end 11 and the opening end 21 and is blocked by the steering valve 30, then the water enters the transition channel 16 of the front section 40 from the cylindrical side surface (namely the filtering surface) of the filter screen 20, the water is divided into two parts, and one part enters the water outlet end 12 from the transition channel 16 and flows out; the other part enters the inner side of the filter screen 20 from the outer side of the filter screen 20 of the rear section 40, and washes impurities adhered to the inner wall of the cylindrical side surface (namely, the filtering surface) of the filter screen 20, and the impurities are brought out from the sewage discharge pipeline 22 together with the impurities temporarily stored in the filter screen 20, so that the washing is completed.

Other content participates in the prior art.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
