[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figure 1 and Figure 2 , a highly efficient dust removal device, comprising an outer shell 1, a sealing assembly 5 installed on the top of the outer shell 1, and two ash discharge bins 2 installed on the outer wall of the bottom of the outer shell 1. A backflush assembly 3 is installed on one outer wall of the outer shell 1;

[0034] An air inlet is provided on the outer wall of one side of the housing 1, and an air inlet pipe 4 for introducing the air to be filtered into the housing 1 is fixedly connected to the inner wall of the air inlet. The sealing assembly 5 for sealing the housing 1 includes a sealing cover 6 fixedly connected to the housing 1. A discharge pipe 7 is installed through the outer wall of the top of the sealing cover 6. One end of the discharge pipe 7 is fixedly connected to a solenoid valve 8. The filtered gas can be directly discharged through the discharge pipe 7 on the sealing cover 6. The setting of the solenoid valve 8 facilitates the control of the power supply to the discharge pipe 7. During the backwashing cleaning process, the solenoid valve 8 closes the discharge pipe 7, thereby reducing the loss of air volume and improving the cleaning efficiency of the backwashing.

[0035] Please refer to Figure 3 and Figure 4 Two ash discharge bins 2 are fixed to the bottom of the housing 1, which facilitates the discharge of the dust and impurities filtered by the dust removal equipment. The backwashing assembly 3 for cleaning the dust removal equipment includes backwashing pipes 9 fixedly connected to the inner walls on both sides of the housing 1. A plurality of blow holes 11 are equidistantly distributed on the outer wall of the backwashing pipe 9. Through the cooperation between the backwashing pipe 9 and the blow holes 11, the backwashing air flow is conveniently transported into the housing 1. The backwashing assembly 3 further includes an electromagnetic pulse valve 10 installed on the housing 1. The electromagnetic pulse valve 10 is communicated with the backwashing pipe 9. The setting of the electromagnetic pulse valve 10 facilitates the control of the on-off of the air flow.

[0036] Please refer to Figure 5 and Figure 6 A partition 12 is installed on the inner wall of the housing 1 below the backwashing pipe 9. Two filtering mechanisms 13 are installed through the partition 12. The filtering mechanism 13 consists of a filtering frame 14 and a dust removal cloth bag 15 sleeved on the outer wall of the filtering frame 14. An installation frame 16 is installed on the inner wall of the filtering frame 14, and two symmetrically arranged vibration assemblies 17 are fixedly arranged on the installation frame 16. The filtering frame 14 facilitates the support of the dust removal cloth bag 15. The setting of the dust removal filter cloth 15 facilitates the filtration of the air entering the housing 1.

[0037] Please refer to Figure 5 , Figure 6 and Figure 7, the vibration component 17 installed on the mounting bracket 16 includes a vibration tube 18 fixedly connected to the mounting bracket 16. Two mounting rods 19 are arranged in the vibration tube 18. A spring 20 is sleeved outside the mounting rods 19. A driving column 21 is slidably mounted on the outer walls of the two mounting rods 19. When the driving column 21 slides, it will compress the spring 20. A vibration block 22 in contact with the dust removal cloth bag 15 is arranged at one end of the driving column 21. An armature 23 is installed at the end of the driving column 21 away from the vibration block 22. An electromagnet 24 matching the armature 23 is installed inside the vibration tube 18. By intermittently energizing the electromagnet 24 in the vibration component 17, when the electromagnet 24 is energized, it generates magnetism, thereby directly attracting the armature 23 to drive the driving column 21 to move. When the driving column 21 moves, while driving the vibration block 22 to move, it compresses the spring 20 on the mounting rod 19. When the electromagnet 24 is de-energized, the spring 20 directly drives the vibration block 22 to impact the dust removal cloth bag 15, so as to facilitate the cleaning of impurities on the dust removal cloth bag 15.

[0038] Working principle: When in use, when it is necessary to clean the dust removal cloth bag 15 in the filtering mechanism 13, the backflush fan is connected to the electromagnetic pulse valve 10. The air flow is transported to the backflush pipe 9 through the electromagnetic pulse valve 10, and then to the dust removal cloth bag 15 through the blowing holes 11 for backflushing. During backflushing, the electromagnet 24 in the vibration component 17 is intermittently energized. When the electromagnet 24 is energized, it generates magnetism, thereby attracting the armature 23 to move towards the electromagnet 24. When the armature 23 drives the driving column 21 to move, it directly compresses the spring 20. When the electromagnet 24 is de-energized, the spring 20 directly drives the driving column 21 to extend. When the driving column 21 extends, it impacts the dust removal cloth bag 15 through the vibration block 22, so as to facilitate the cleaning of the dust and impurities adhered to the dust removal cloth bag 15. When the electromagnetic pulse valve 10 is opened, the solenoid valve 8 closes the exhaust pipe 7.
