[0009] Optionally, the arc-shaped annular plate movably passes through the side of the back-blowing box, the back-blowing plate is a hollow plate, a circular array of back-blowing pipes is arranged on one side of the back-blowing plate, and a central tube is fixedly arranged at the center position of the side of the back-blowing plate.

[0010] Optionally, the position of the backflush pipe corresponds to the position of the filter hole one by one, and the backflush box is fixedly provided with a dirt outlet hopper at the bottom of the outer side of the sample tube.

[0011] Optionally, the bottom of the sample tube is in an inverted bucket shape, and butterfly valves are provided at the bottom of the sample tube and the bottom of the sewage outlet hopper.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The arc-shaped ring plate provided in the utility model is the filtering structure of the device, and the arc-shaped ring plate is set on the top of the sample tube by rotating through a servo motor. When the filtering structure needs to be cleaned, the filtering hole of the arc-shaped ring plate can be moved to the recoil assembly for recoil by starting the servo motor, and then the filtering hole is driven back to the initial position by the servo motor.
