Further, the monitoring instruments and detection instruments are pressure sensors.

Further, the filter box has a cuboid structure, the interior of which is a circular open steel pipe, and the interlayer is filled with concrete.

Further, the bypass pipe is a U-shaped elbow.

Further, the sewage outlet is made of cuboid steel plate and welded to the lower part of the filter box.

Further, the first valve, the second valve and the third valve are all automatic control valves. When the difference between the value of the monitoring instrument and the value of the detection instrument exceeds the set range, the external control system automatically closes the first valve and the third valve. Second valve, open third valve.

Compared with the prior art, the beneficial effects of the present utility model are:

The utility model adopts the method of arranging a U-shaped bypass pipe on the main pipeline, and arranging monitoring instruments and detection instruments at the front and rear ends of the main pipeline. When water flows freely in the main pipeline, the third valve is in a closed state, and when the monitoring instrument When the difference between the data of the monitoring instrument and the data of the monitoring instrument is greater than the set range, the third valve is automatically opened, the first valve and the second valve are automatically closed, the water is discharged through the bypass pipe, and the automatic control system alarms. The manual operation of the operator can realize automatic detection and control, which greatly reduces the labor intensity of the operator, significantly reduces the equipment failure rate caused by impurity blockage, and improves the equipment efficiency.
