[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] An explosion-proof dust removal filter cartridge provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0021] Combination Figure 1-2 As shown, the utility model provides an explosion-proof dust removal filter cartridge, comprising: a filter cartridge assembly 100 and a cleaning assembly 200; wherein the filter cartridge assembly 100 comprises a filter element 110 and a fixing ring 120 disposed at the end of the filter element 110;

[0022] The cleaning assembly 200 is arranged on the filter element 110, and the cleaning assembly 200 includes a mounting box 210 mounted on the end of the filter element 110, an exhaust pipe 220 arranged on the mounting box 210, a servo motor 230 mounted on the outside of the mounting box 210, a vibrator 240 fixed to the driving end of the servo motor 230, a shunt pipe 250 fixed to the driving end of the vibrator 240 and extending into the filter element 110 through the mounting box 210, an air inlet pipe 260 connected to the shunt pipe 250 and located outside the mounting box 210, a telescopic air pipe 270 mounted on the shunt pipe 250 and located in the filter element 110, and a shunt pipe 270 fixed to the telescopic air pipe 2 The diverter plate 280 at the end of 70 and the nozzle 290 arranged on the diverter plate 280 can introduce clean gas from the air inlet pipe 260 into the diverter pipe 250 through the cleaning component 200, and then the telescopic air pipe 270 is extended under the action of air pressure, so that the diverter plate 280 is against the filter element 110. At this time, the clean gas is sprayed out through the nozzle 290 to flush the filter element 110 at a close distance. At the same time, the vibration generated by the vibrator 240 can also be transmitted to the filter element 110 through the diverter pipe 250, the telescopic air pipe 270 and the diverter plate 280. After cleaning is completed once, the telescopic air pipe 270 is retracted, and the servo motor 230 is used to drive the diverter pipe 250 to rotate appropriately, adjust the position of the diverter plate 280, and repeat the cleaning.

[0023] Specifically, a rubber block 231 is connected between the servo motor 230 and the vibrator 240 , which can reduce the vibration generated by the vibrator 240 from being transmitted to the servo motor 230 , thereby ensuring the normal operation of the servo motor 230 .

[0024] Furthermore, a spring 211 located on the outside of the diverter pipe 250 is fixed in the installation box 210, and a baffle 212 mounted on the diverter pipe 250 is fixed at the end of the spring 211, which can seal the fixing ring 120. During normal operation, the clean gas will push the baffle 212 open and be discharged from the exhaust pipe 220. During cleaning, the pressure is not enough to push the baffle 212 open, so that most of the cleaned air passes through the filter element 110 and is discharged outward, preventing it from entering the exhaust pipe 220. This is more practical.

[0025] On the other hand, a positioning ring 111 which is fitted on the end of the diverter tube 250 is fixed in the filter element 110 , so as to have a positioning effect on the diverter tube 250 .

[0026] It should be noted that the diverter pipe 250 is provided with air holes 251 located between the telescopic air pipes 270, so that a proper amount of cleaning gas can be discharged from the air holes 251 to clean the parts not cleaned by the nozzle 290, thereby improving the cleaning effect.

[0027] Furthermore, the diverter plate 280 is an arc-shaped plate structure disposed around the diverter pipe 250, so that it can be closely attached to the inner wall of the filter element 110 for comprehensive cleaning, and the cleaning effect is better.

[0028] The working principle and use process of the utility model are as follows: when the filter element 110 needs to be cleaned, clean gas is introduced from the air inlet pipe 260 into the diverter pipe 250, and then the telescopic air pipe 270 is extended under the action of air pressure, so that the diverter plate 280 is against the filter element 110. At this time, the clean gas is sprayed out through the nozzle 290 to wash the filter element 110 at a close distance. At the same time, the vibration generated by the vibrator 240 can also be transmitted to the filter element 110 through the diverter pipe 250, the telescopic air pipe 270 and the diverter plate 280. After cleaning once, the telescopic air pipe 270 is retracted, and the servo motor 230 is used to drive the diverter pipe 250 to rotate appropriately, adjust the position of the diverter plate 280, and repeat the cleaning.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
