[0003] The existing pulse dust removal of the filter cartridge structure is to remove dust by delivering airflow to one end of the filter cartridge. During this process, the airflow flows out from the unobstructed part of the filter cartridge structure, and each layer of filter holes cannot be carefully cleaned, thereby reducing the cleaning effect of the filter cartridge structure.

[0004] Therefore, those skilled in the art have proposed a cartridge type pulse dust collector to solve the problems raised in the above background. Summary of the invention

[0005] The object of the present invention is to provide a cartridge type pulse dust collector to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A cartridge type pulse dust collector comprises a box body, a plurality of support frames are fixedly mounted on one side of the box body, and further comprises: An air inlet pipe, wherein the air inlet pipe is fixedly connected to the box body; An air outlet pipe, wherein the air outlet pipe is fixedly connected to the box body; A pulse dust removal structure, the pulse dust removal structure includes a filter cartridge structure fixedly installed in a box body, an air pressure control module is installed on the outside of the box body, the air pressure control module is connected to a sliding frame through a hose, the sliding frame is connected to the sliding frame through a hydraulic drive module, a bellows is fixedly installed on one side of the sliding frame, one end of the bellows is connected to the hose, and the other end of the bellows is connected to a sliding nozzle through a solenoid valve.

[0007] As a further improvement of the present invention: the hydraulic drive module includes a fixing frame fixedly installed inside the box body, the fixing frame is fixedly connected to a hydraulic rod, and the end of the hydraulic rod is fixedly installed with a connecting plate fixedly connected to the sliding frame.

[0008] As a further improvement of the present invention: the air pressure control module includes an air box fixedly connected to the box body, a reversing valve is fixedly installed in the air box, the reversing valve is fixedly connected to a hose, the reversing valve is connected to an air pump, the reversing valve is connected to an air extraction pump, and both the air extraction pump and the air pump are fixedly installed in the air box.

[0009] As a further improvement of the present invention: a plug plate is movably installed at the bottom of the box.

[0010] As a further improvement of the present invention: the sliding nozzle includes a column shell fixedly connected to the electromagnetic valve, a plurality of filter screens connected to the outer surface of the column shell are installed on one side surface of the column shell, and a circular support frame is fixedly installed outside the column shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The dust-containing gas enters from the air inlet pipe, is filtered by the filter cartridge structure, and then exits from the air outlet pipe. After the dust removal work is completed, the hydraulic drive module drives the sliding frame to move, and the sliding frame simultaneously drives the hose, bellows, solenoid valve, and sliding nozzle to move synchronously. When the sliding nozzle moves to the filter cartridge structure, the air pressure control module supplies air and the solenoid valve opens, so that the sliding nozzle uses the high-speed ejected gas to clean the filter cartridge structure layer by layer during the fall, thereby improving the cleaning effect of the filter cartridge structure. Then the solenoid valve is closed, the air pressure control module exhausts air, and the bellows drives the sliding nozzle to reset during the contraction. The present invention improves the cleaning effect of the pulse dust collector on the filter cartridge structure. BRIEF DESCRIPTION OF THE DRAWINGS
