[0032] The cleaning unit 4 can extend into the interior of the dust collection barrel 1 and into the interior of the annular cylinder of the filter element 6. After the cleaning unit 4 is started, it can blow air from the interior of the filter element 6 toward the outside to blow out the metal dust attached to the filter element 6. Since the filter element 6 can rotate under the drive of the rotating unit 2, the cleaning unit 4 can perform comprehensive and fine cleaning on the entire filter element 6, effectively improving the cleaning effect;

[0033] The negative pressure unit 3 is connected to the dust collection barrel 1. The negative pressure unit 3 can cooperate with the cleaning unit 4 to form a relative negative pressure, so that most of the metal dust blown out by the cleaning unit 4 can fall to the bottom of the dust collection barrel 1, and a small part can be sucked into the negative pressure unit 3.

[0034] The dust collection barrel 1 can temporarily form a relatively sealed space to collect the metal dust blown out from the filter element 6, effectively preventing the metal dust from being blown around, protecting the surrounding environment, preventing operators from being exposed to a large amount of metal dust, and ensuring the health of operators;

[0035] The metal dust that falls to the bottom of the dust collection barrel 1 can be collected uniformly after the operation is completed. In this embodiment, a vacuum cleaner can be preferably used to collect the metal dust, which is more convenient and quick to operate.

[0036] As an optional embodiment, the base 5 includes a support column 51 and a bottom plate 52. The bottom of the support column 51 is connected to the bottom plate 52, and the upper and middle parts of the support column 51 are connected to the dust collection barrel 1. The bottom plate 52 has a larger cross-sectional area, which can make the overall structure more stable. The support column 51 can lift the dust collection barrel 1 and the rotating unit 2 to a certain height, which is beneficial to subsequent cleaning operations.

[0037] As an optional embodiment, the dust collection barrel 1 includes a barrel body 11 and a cover body 12. The barrel body 11 is the main structure of the dust collection barrel 1 and has a large volume, so that the filter element 6 can be placed as a whole inside the barrel body 11 and leave enough cleaning operation space. The bottom of the barrel body 11 is connected to the support column 51, and the connection here is preferably a fixed connection to improve the structural strength. The cover body 12 is detachably connected to the top of the barrel body 11. When taking and placing the filter element 6, it is necessary to lift the cover body 12.
