Description

Technical Field

[0002] With the acceleration of industrialization and the continuous improvement of people's requirements for the quality of living environment, vacuum cleaners, as an important cleaning equipment, are widely used in many fields such as industrial production, commercial operation and home life. Pulse back-blowing vacuum cleaners are a type of cleaning equipment commonly used in industrial and commercial environments. They are very useful in industrial environments that require efficient and continuous cleaning, especially in places with a lot of dust. They can ensure the smooth progress of cleaning work, reduce human intervention and improve production efficiency.

[0003] Existing pulse jet vacuum cleaners have several problems in actual operation. For example, a pulse jet vacuum cleaner with a two-stage filtration system (publication number CN222076147U) can replace the collection bag through the design of tightening ring one, tightening ring two, and pins, but it still requires multiple manual operations, resulting in low work efficiency. Furthermore, it cannot automatically close the dust discharge port during collection bag replacement, causing dust to easily spill and pollute the environment, making it environmentally unfriendly. It also cannot easily and stably replace and reposition filter bags or cartridges after prolonged use, making it impractical. Moreover, existing pulse jet vacuum cleaners typically have pulse jet nozzles at the top of the filter cartridge, but the cleaning power of the compressed gas sprayed from the nozzles is greatly reduced when it reaches the bottom of the filter cartridge, failing to provide a comprehensive and uniform back-blowing cleaning. Therefore, there is a need for an environmentally friendly pulse jet vacuum cleaner to meet user needs. Summary of the Invention

[0015] Compared with related technologies, the present invention has the following beneficial effects:

[0016] 1. This invention, through the cooperation of the limiting rod and the positioning frame, can conveniently complete the locking and fixing and disassembly / separation of the first and second housings. In the locked state of the first and second housings, the collected dust and impurities can be conveniently transferred and processed by the hydraulic rod and the high-efficiency dust removal component to complete the dust removal work by means of the hydraulic rod driving and the self-positioning installation component. In the separated state of the first and second housings, the filter cartridges can be disassembled and replaced in batches by the hydraulic rod driving and the self-positioning installation component, which increases the functionality of the pulse back-blowing vacuum cleaner and improves its practicality and convenience.

[0017] 2. This invention, through the telescopic sleeve and the second spring, can push the cover frame to move automatically downward when the second housing moves upward. At this time, combined with the third spring and the slider, it can drive the sealing plates on both sides to automatically engage with the discharge pipe, realizing the automatic closure of the discharge pipe. This avoids the continuous spillage of dust from inside the vacuum cleaner during the cleaning process, preventing environmental pollution. Furthermore, the collection frame can conveniently and stably transfer and clean the collected dust, which can be reused. When the second housing moves downward to reset, it can push the sealing plates on both sides to automatically disengage from the discharge pipe, completing the automatic opening. This ensures the stability of subsequent dust and impurity discharge and collection, effectively improving the environmental friendliness of the pulse back-blowing vacuum cleaner, while further enhancing its practicality and convenience.

[0018] 3. This invention, through the separation of the first and second housings using limiting rods and positioning frames, allows the first housing to move away from the second housing and each filter cartridge via hydraulic rods. This enables convenient and stable batch or individual replacement of each filter cartridge. When the first housing moves downwards to reset, the connecting plate pushes each filter cartridge downwards automatically, pushing the first piston. At this time, under air pressure, combined with the second piston and plug rod, each clamping plate moves towards the center simultaneously, automatically clamping and fixing the positioning rod on the base. This allows for automatic and stable clamping, fixing, and positioning of the filter cartridges on the base, automatically completing the batch positioning and installation of filter cartridges. This effectively improves the working efficiency of the pulse jet vacuum cleaner and extends its service life.

[0019] 4. This invention controls electromagnetic pulse valves through a pulse controller, which, combined with an air compressor, delivers compressed air to each of the first blowpipes. During the delivery process, the airflow drives the guide fan blades to rotate automatically, which in turn drives the first blowpipes to rotate automatically. At the same time, under the spiral guidance of the first and second connecting pipes, the airflow stroke is increased. Through nozzles of different heights, compressed gas can be jetted in stages. In conjunction with the automatic rotation of the first blowpipes, the upper, middle, and lower parts of the filter cartridge can be jetted gradually, thereby causing the dust adhering to the outside of the filter cartridge to gradually detach from top to bottom, achieving the effect of pulse backflushing cleaning. At the same time, it can effectively improve the cleaning effect of pulse backflushing.

[0051] The specific implementation process of this invention is as follows: First, the operator can push the pulse back-blowing vacuum cleaner by holding the fixed handle 24 on the first housing 4. The universal wheels 10 on the base plate 1 can ensure that the pulse back-blowing vacuum cleaner can be moved easily until it is moved to the working position. Then, by driving the turbine fan 15 on the first housing 4, the turbine fan 15 can perform negative pressure suction in the first housing 4 and the second housing 5. Under the action of negative pressure suction, the dust can be sucked through the suction pipe 13 on the guide frame 11. At this time, the dust-laden gas enters the guide frame 11 through the suction pipe 13 and enters the first housing 4 and the second housing 5 through the guide groove 12 at the bottom of the guide frame 11. After being filtered by the filter cartridge 18, the dust-laden gas can be transported to the fixed pipe 14 through the first through groove 17 on the connecting plate 16, and then discharged by the drive of the turbine fan 15, thus completing the dust suction work.

[0052] During the operation of the vacuum cleaner, the pulse controller 713 controls the electromagnetic pulse valve 703 and the air compressor 701. By adjusting the frequency of the pulse controller 713, the number of air jets per unit time of the electromagnetic pulse valve 703 and the air compressor 701 is controlled to perform backflushing cleaning of the filter cartridge 18. After the electromagnetic pulse valve 703 and the air compressor 701 are opened, the compressed gas is delivered to each of the third air ducts 705 through the first air duct 702 and the second air duct 704, and then delivered to each of the first blowpipes 706. At this time, under the action of gas delivery, the airflow can drive the guide fan blades 712 to rotate automatically, which in turn can drive the first blowpipes 706 to rotate automatically. Then, the compressed gas is first ejected through each nozzle 711 on the first blowpipe 706, and then, under the guidance of the first connecting pipe 707, it is ejected through the second blowpipe. The nozzles 711 on the blowpipe 708 spray out gas, and similarly, under the guidance of the second connecting pipe 709, the nozzles 711 on the third blowpipe 710 spray out gas. In summary, under the spiral guidance of the first connecting pipe 707 and the second connecting pipe 709, the airflow stroke can be increased. The compressed gas can be sprayed in stages through the nozzles 711 at different heights. In addition, with the automatic rotation of the first blowpipe 706, the second blowpipe 708 and the third blowpipe 710 can be driven to rotate synchronously, which in turn can drive the nozzles 711 to rotate stably. This allows for a comprehensive and uniform pulse jet spray to be applied to the upper, middle and lower parts of the filter cartridge 18, so that the dust adhering to the outside of the filter cartridge 18 can be gradually removed from top to bottom, achieving the effect of pulse backflushing cleaning and effectively improving the cleaning effect of pulse backflushing.

[0053] During the operation of the vacuum cleaner, large dust particles enter the second chamber 5 first under the action of gravity, and fall into the collection frame 23 through the discharge pipe 911 for automatic collection. The dust on the outside of the filter cartridge 18, after being pulsed back-blown, can also fall into the collection frame 23 for automatic collection under the action of gravity through the discharge pipe 911. After the vacuum cleaner finishes working, the operator can drive the hydraulic rod 2. At this time, the hydraulic rod 2 can drive the first chamber 4 to move upward through the support plate 3, and then drive the second chamber 5, which is connected, to move upward synchronously.

[0054] Under the movement of the second housing 5, the cover frame 904 can be driven to move upward and separate from the collection frame 23. At this time, under the elastic action of the second spring 903 inside the telescopic sleeve 902, the cover frame 904 can be pushed to move downward automatically. Under the movement of the cover frame 904, the sealing plate 909 can be driven to move downward synchronously through the slider 908 in the slide groove 906. When the sealing plate 909 moves to the third through groove 912 on the feed pipe 911, under the elastic action of the third spring 907 inside the slide groove 906, it will... The slider 908 can push the sealing plate 909 to automatically engage with the third through groove 912 on the feed tube 911. At this time, under the engaging action of the sealing plates 909 on both sides, combined with the first sealing strip 910 and the second sealing strip 913, the feed tube 911 can be automatically sealed and closed. This prevents dust from continuously falling from the vacuum cleaner during the cleaning process and causing environmental pollution. The collection frame 23 can be used to conveniently and stably transfer and clean the collected dust, and it can be reused.

[0055] After use, the collection frame 23 can be placed back into the limiting frame 22, and the first box 4 and the second box 5 will be driven to move downwards and reset by the hydraulic rod 2. At this time, under the action of the movement of the second box 5, the cover frame 904 can be driven to move downwards and contact the collection frame 23. At this time, under the blocking action of the collection frame 23, the cover frame 904 can move towards the second box 5. At this time, under the relative movement of the cover frame 904 and the second box 5, the cover frame 904 can push the sealing plate 909 to automatically move away from the third through groove 912 on the feed pipe 911 through the guide of the inclined surface of the sealing plate 909, so as to realize the automatic opening of the feed pipe 911 and ensure the stability of the subsequent dust and impurity feeding and collection work.

[0056] Furthermore, when the filter cartridge 18 needs to be replaced after the vacuum cleaner has finished working, simply push the stop block 28 into the limit rod 26 so that it is not blocked by the positioning frame 29, and the disassembly and separation between the first housing 4 and the second housing 5 can be completed. At this time, the hydraulic rod 2 can only push the first housing 4 upward and separate it from the second housing 5. The second housing 5 does not move. At this time, under the action of the movement of the first housing 4, the pulse back-blowing component 7 can be driven to move and detach from the filter cartridge 18. Then the staff can pick up and place the filter cartridge 18 to replace it.

[0057] After the filter cartridge 18 is replaced, simply insert the positioning rod 21 on the bottom base 20 of the filter cartridge 18 into the positioning groove 803 on the air storage frame 802. Then, driven by the hydraulic rod 2, the first housing 4 moves downward to reset. At this time, the first housing 4 can push each filter cartridge 18 to move downward automatically through the connecting plate 16. The filter cartridge 18 can push the first piston 806 on the first spring 805 to move downward using the positioning rod 21. At this time, the air in the air storage frame 802 can be delivered to the air storage frame 802 through the first air supply pipe 807. Inside the second air supply pipe 808, under the action of air pressure, the second piston 809 inside the second air supply pipe 808 can push the clamping plate 811 to move towards the middle through the plug rod 810. At this time, under the action of the movement of each clamping plate 811, the positioning rod 21 on the base 20 can be automatically clamped and fixed, thereby enabling the filter cartridge 18 on the base 20 to be automatically and stably clamped, fixed and positioned for installation, automatically completing the batch positioning and installation of the filter cartridge 18, ensuring the stability and safety of the filter cartridge 18 in subsequent working state;

[0058] At the same time, the fixing plate 25 on the first housing 4 can drive the limiting rod 26 to automatically insert into the positioning frame 29 on the second housing 5. Under the guidance of the inclined surface at the end of the stop block 28, the limiting rod 26 can drive the stop block 28 to automatically pass through the positioning frame 29. Furthermore, the fourth spring 27 can drive the stop block 28 to automatically move outward and reset. The combination of the limiting rod 26 and the positioning frame 29 can easily complete the locking and fixing between the first housing 4 and the second housing 5, ensuring the stability of the vacuum cleaner's subsequent working state.
