Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector cleaning technology, specifically a dust collector cleaning mechanism for explosion-proof dust collectors. Background Technology
[0002] Explosion-proof dust collectors are dust removal devices specifically designed to handle dust that poses an explosion risk in industrial environments. Their primary purpose is to effectively collect and filter dust while ensuring the safety of equipment and personnel in the event of an accidental explosion. Many explosion-proof dust collectors are equipped with pulse-jet cleaning functionality. Pulse-jet cleaning is a common method for cleaning filter cartridges; it uses a high-pressure pulsed airflow to instantly impact the filter media, rapidly removing dust accumulated on the surface.
[0003] When the dust collector detects an increase in the differential pressure of the filter cartridges, indicating that dust accumulation has reached a certain level, the control system automatically triggers the cleaning program. The control system activates the pulse valve, releasing stored compressed air. This air is typically delivered rapidly to the pulse nozzles via an air tank or air source. The high-pressure pulse airflow is instantly ejected through the nozzles and simultaneously enters the filter cartridges. This airflow rapidly diffuses and generates a powerful impact force, instantly stripping and blowing off dust and particles adhering to the filter media surface, effectively reducing the resistance of the filter cartridges.
[0004] However, the existing pulse cleaning process still has the following shortcomings:
[0005] Existing nozzles are generally located at the air outlet of the filter cartridge. After the high-pressure pulsed airflow enters the filter cartridge, it cannot make timely and uniform contact with the filter material. Furthermore, the air outlet of the filter cartridge is in an open state during the pulsed airflow, and part of the energy of the pulsed airflow is released to the external environment. This causes the airflow to be unable to concentrate inside the filter cartridge, reducing the impact force and resulting in the inability to effectively remove the accumulated dust. Utility Model Content
[0006] The purpose of this utility model is to provide a dust removal mechanism for an explosion-proof dust collector to solve the problems mentioned in the background art.

[0034] The housing 1 is provided with a blowing mechanism located above the partition 7. The blowing mechanism includes a lifting component disposed between the partition 7 and the inner top surface of the housing 1. The lifting component is driven to install the blowing component.
[0035] The spray assembly includes an air supply assembly, which is connected to multiple sets of nozzle assemblies. The number of multiple sets of nozzle assemblies is equal to the number of multiple mounting slots 18, and they are aligned one by one.
[0036] The gas supply component includes a conduit 8 that runs through the side of the housing 1 near the top. One end of the conduit 8 located inside the housing 1 is fixedly connected to a telescopic bellows 12. The other end of the conduit 8 away from the telescopic bellows 12 is connected to a gas cylinder. A pulse valve 9 connected to the dust collector control system is installed in the conduit 8.
[0037] An air guiding component is fixedly connected to the end of the telescopic bellows 12 away from the duct 8.
[0038] The air guiding assembly includes two parallel air guiding pipes 14. A second air guiding pipe 22 is fixedly connected between the middle positions of the two air guiding pipes 14 and passes through the two air guiding pipes 14. A connecting pipe 13 is fixedly installed through the middle position of the outer periphery of the second air guiding pipe 22. The end of the connecting pipe 13 away from the second air guiding pipe 22 is fixedly connected to the end of the telescopic corrugated pipe 12 away from the guide pipe 8.
[0039] A connecting rod 19 is fixedly connected between the two ends of the two air guide tubes 14, and a connecting plate 20 is provided in the middle of the connecting rod 19.
[0040] The lower side of the air duct 14 is fixedly connected to multiple nozzle assemblies arranged in an array along the length of the air duct 14.
[0041] The nozzle assembly includes a blow pipe 16 that is fixedly connected to the air duct 14, and a conical plug 15 is installed on the periphery of the blow pipe 16 near the air duct 14.
[0042] Multiple evenly distributed blow holes 17 are provided on the periphery of the blow pipe 16.
[0043] The lifting assembly includes a motor 11, a screw 10, and a slide rod 21. The screw 10 is rotatably installed between the top surface of the partition 7 and the inner top surface of the box 1, and the slide rod 21 is fixedly installed between the top surface of the partition 7 and the inner top surface of the box 1.
[0044] The screw 10 is threaded through one connecting disc 20, and the slide rod 21 slides through another connecting disc 20;

[0046] When using this utility model:
[0047] During dust removal, the motor 11 first drives the screw 10 to rotate.

The airflow in the first air guide pipe 14 enters the multiple blow pipes 16, and then is sprayed out through the multiple blow holes 17 into the filter cartridge 6.
[0048] In this invention, the nozzle assembly allows the blowpipe 16 to extend into the filter cartridge 6, ensuring that the blowhole 17 is evenly aligned with the filter material in the cartridge 6. This allows the pulsed airflow to act directly and evenly on the filter material, effectively removing dust and particles adhering to the surface of the filter material and improving the cleaning effect. Simultaneously, the conical plug 15 seals the air outlet of the filter cartridge 6, concentrating the pulsed airflow inside the cartridge 6 and creating a higher pressure difference. This more effectively impacts and peels off the adhering substances, making the cleaning more thorough and further improving the cleaning effect.
