[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1 to 3 As shown, a high-efficiency filter cartridge cleaning device includes a filter cartridge 1, an air outlet shaped part 2, an air tank 3, a pulse valve 4, a pulse valve hollow tube 5, a pneumatic valve 6, a pneumatic valve shaft 7, a valve plate 8, and a blowing pipe 9.

[0021] The air outlet shaped part 2 cooperates with the air outlet of the filter cartridge 1 . The air outlet shaped part 2 is an iron structure and can better withstand the extrusion of the valve plate 8 compared with the traditional plastic structure.

[0022] The gas tank 3 is connected to the pulse valve 4, and the pulse valve 4 is connected to the pulse valve hollow tube 5. The other end of the pulse valve hollow tube 5 passes through the air outlet shaped part 2 and extends into the filter cartridge 1, and the end extending into the interior of the filter cartridge 1 is in an L-shaped structure.

[0023] The pneumatic valve 6 is connected to the pneumatic valve shaft 7. The pneumatic valve 6 and the pulse valve 4 are both controlled by a pulse controller. The pneumatic valve shaft 7 is connected to the valve plate 8. The valve plate 8 is adapted to the end surface size of the air outlet shaped part 2 and is used to abut against the end surface of the air outlet shaped part 2 during cleaning, so that a sealed space is formed inside the filter cartridge 1 to increase the back-blowing air pressure and improve the cleaning effect.

[0024] The spray pipe 9 is distributed in parallel inside the filter cartridge 1, and is threadedly connected to the L-shaped end of the pulse valve hollow tube 5. The diameter of the spray pipe 9 is 32 mm, and a spray hole 10 with a diameter of 6 mm is opened on its surface. In the present embodiment, the spray holes 10 are distributed in four rows along the circumference of the spray pipe 9, and each row has five holes distributed along the axial direction of the spray pipe 9. The direction of the spray holes 10 is perpendicular to the axial direction of the spray pipe 9, so that the air pressure released instantly during the spraying can be more evenly distributed in the filter cartridge. Under the same air pressure, the newly added tube with holes has a better cleaning effect.

[0025] The working principle and use process of this utility model:

[0026] During dust cleaning, the pulse controller controls the pneumatic valve 6 to push the valve plate 8 forward through the pneumatic valve shaft 7 to abut against the end face of the air outlet shaped part 2, so that the filter cartridge 1 forms a closed space; the pulse controller controls the pulse valve 4 to spray, and the air pressure released in an instant when the gas is sprayed out through the spray hole 10 on the spray pipe 9 is distributed more evenly in the filter cartridge, thereby improving the dust cleaning effect.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
