One side of the top of the fixed cylinder near the rear end cover is provided with an exhaust pipe. A cleaning component for cleaning the filter cylinder is installed through the rear end cover. A discharge pipe is fixedly connected to the lower part of the middle of the filter cylinder, and the bottom of the discharge pipe is connected to a collection box. The collection box is detachably installed with a box cover at the top, and a filter screen is installed inside. One end is fixedly connected to a connecting pipe, and an air outlet pipe is provided on one side of the top of the box cover.

[0007] Further, both ends of the filter cylinder are of a double-cone structure, and both ends thereof are respectively abutted against the front end cover and the rear end cover.

[0008] Further, a positioning ring is fixedly connected to the inner side of the front end cover, and a positioning seat is fixedly connected to the inner side of the rear end cover. Positioning grooves adapted to both ends of the filter cylinder are provided on both the positioning ring and the positioning seat.

[0009] Further, the cleaning component includes a central shaft, the central shaft is rotationally installed on the rear end cover through a mounting seat, and two mounting bars are symmetrically installed on the central shaft. Brushes are installed on the mounting bars, and a handwheel is installed at one end of the central shaft.

[0010] Further, solenoid valves are installed on both the exhaust pipe and the discharge pipe.

[0011] Further, a mounting ring is fixedly connected to the upper end inside the collection box, and the filter screen is installed on the mounting ring.

[0012] Further, the connection part of the connecting pipe and the collection box is located below the mounting ring, and a sleeve that can be sleeved outside the discharge pipe is fixedly connected to the outer side of one end of the connecting pipe.

[0013] The advantages of the present utility model compared with the existing technology are as follows: By rotating the central shaft through the handwheel, the central shaft drives the mounting bars and the brushes to rotate, so that the dust attached to the inner wall of the filter cylinder can be brushed off. Open the solenoid valve on the discharge pipe and close the solenoid valve on the exhaust pipe, so that the dust inside the filter cylinder follows the air flow into the collection box and stays inside the collection box under the action of the filter screen, completing the cleaning of the inner wall of the filter cylinder. The equipment works normally throughout the process, improving the efficiency of air pollution control. Description of the Drawings
