The working principle of the water inlet sampling and filtering device of the sewage treatment plant is as follows:

at first installation water tank 1, first when installing inlet tube 7, in vertical direction, the delivery port of inlet tube 7 will be less than the water inlet of inlet tube 7, because the delivery port of inlet tube 7 bears different atmospheric pressure with the water inlet of inlet tube 7, sewage can be by the big one side of pressure flow direction pressure little one side, sewage flows to the delivery port of inlet tube 7 from the water inlet of inlet tube 7 promptly to inlet tube 7 takes out sewage to in the water tank 1.

Secondly, also can be equipped with inlet pump 10 respectively on inlet branch 8 and inlet tube 7 for when the delivery port of inlet tube 7 will be less than the water inlet of inlet tube 7, inlet tube 7 also can be taken sewage to water tank 1 in. Then the sampling tube is inserted into the semi-enclosed structure enclosed by the filter screen 2 through the through hole 4 on the box cover 3.

Can be manually controlled or automatically controlled:

during manual control, inlet tube 7 and water inlet branch 8 take out the sewage that will detect to the cavity of water tank 1, and the sewage that will detect gets into water tank 1 back, flows in the semi-surrounding structure that filter screen 2 encloses through the aperture on the filter screen 2 in, has played a filterable effect, completely cuts off the floater outside filter screen 2, can effectually prevent the jam of suspended solid to the sampling tube. When the sewage in the water tank 1 reaches a certain height, the sewage flows out of the drain pipe 6 through the overflow pipe 5 under the action of gravitational potential energy. Through adjusting the aperture of the water inlet valve 9, the water inlet pipe 7 and the overflow pipe 5 work continuously, so that the sewage in the water tank 1 flows and updates continuously, the sampling pipe is ensured to collect the continuously flowing sewage, and the change condition of the sewage can be monitored in real time.

Then the switch of the electric push rod 12 is opened at intervals, so that the electric push rod 12 drives the sliding sleeve 11 to move up and down outside the filter screen 2, the brush cleans suspended matters attached to the outer side of the filter screen 22 at regular time, the filter screen 22 is protected from being blocked by the suspended matters, and the suspended matters are prevented from influencing the normal work of the sampling tube.

During automatic control, the sewage that inlet tube 7 and water inlet branch 8 will detect is taken out to the cavity of water tank 1, and the sewage that will detect gets into water tank 1 back, flows into the semi-surrounding structure that filter screen 2 encloses through the aperture on filter screen 2 in, has played a filterable effect, completely cuts off the floater outside filter screen 2, can effectually prevent the jam of suspended solid to the sampling tube. When the sewage in the water tank 1 reaches a certain height, the sewage flows out of the drain pipe 6 through the overflow pipe 5 under the action of gravitational potential energy. The liquid level sensor monitors water in the water tank 1, when the water level reaches a set height, the liquid level sensor sends a signal to the PLC, then the PLC controls the opening of the water inlet valve 9 according to the received signal, so that the water inlet pipe 7 and the overflow pipe 5 work continuously, the sewage in the water tank 1 continuously flows and is updated, the sampling pipe is guaranteed to collect the continuously flowing sewage, and the change condition of the sewage can be monitored in real time.

When intaking, time relay begins the timing, and the back is accomplished in the timing, PLC control electric push rod 12 action, makes electric push rod 12 drive slip cap 11 reciprocate in the 2 outsides of filter screen, and the brush is to pasting the suspended solid in the filter screen 22 outside regularly clearing up, then time relay begins new round timing, and protection filter screen 22 is not blockked up by the suspended solid, prevents that the suspended solid from influencing the sampling tube and normally work.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
