Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment and relates to an internal device of a vacuum cleaning equipment, specifically an offline dust removal device for vacuum cleaning filter materials. Background Technology

[0002] With the rapid development of modern industry, dust pollution has become increasingly serious. Controlling dust pollution and purifying the human living environment has become a national consensus. In particular, processes such as grinding, polishing, sanding, material feeding, and welding generate large amounts of dust during production, significantly impacting production and employee welfare. Existing dust collectors are dry filtration devices. They are suitable for collecting fine, dry, non-fibrous dust. The filter cartridge filters dust-laden gas. When the dust-laden gas enters the mobile dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified by trapping the dust as it passes through the filter media.

[0003] For existing dust collectors, on the one hand, the filter cartridges are mutually restrictive and cannot operate independently, and the dust collector is forced to stop when the filter cartridges are repaired; on the other hand, the dust accumulation outside each filter cartridge in the dust collection equipment is different, and each cleaning requires the entire machine to be shut down for cleaning, which cannot meet the current factory's need for continuous and uninterrupted dust filtration, and its practicality is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model aims to provide an offline dust removal device for vacuum cleaning filter materials, so as to enable the filter cartridge to clean itself according to the amount of dust accumulation, without affecting the overall operation of the equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vacuum cleaning filter material offline cleaning device includes multiple offline cleaning units. Each offline cleaning unit is hollow inside, with a through hole in the center of the top, a connecting flange on the outer side of the top, and a dust hopper at the bottom. A backflush pipe is inserted into the center of the through hole. Two first baffles are symmetrically fixed on the outer wall of the backflush pipe according to its central axis. The end of each first baffle away from the backflush pipe is fixedly connected to the inner wall of the through hole. A rotating ring is provided below the connection between the two first baffles and the outer wall of the backflush pipe. Two first baffles are symmetrically arranged on the rotating ring. Two second baffles are provided inside the backflush pipe. The two second baffles are symmetrically arranged according to the central axis of the backflush pipe. A connecting shaft is provided at the connection between the two second baffles. A rotating shaft is sleeved on the lower part of the connecting shaft. Two second baffles are symmetrically arranged on the rotating shaft according to its central axis.

[0007] Two torsion springs are fixedly installed on the bottom surfaces of the first baffles respectively. A base plate is fixedly installed at the end of the torsion spring away from the first baffle. A spring torsion bar is installed at the center of the base plate. The end of the spring torsion bar away from the center of the base plate is fixedly connected to the rotating shaft.

[0008] As a limitation of this utility model, a first stop block is fixedly provided on one side of the bottom of each of the two first baffles; a second stop block is provided on one side of the top of each of the two second baffles, and the two first stop blocks and the two second stop blocks are centrally symmetrical about the central axis of the backflush pipe.

[0009] As another limitation of this utility model, each of the first partition, the second partition, the first baffle and the second baffle is fan-shaped, wherein each of the first partition and the first baffle is 1 / 4 of the area of ​​the through hole, and each of the second partition and the second baffle is 1 / 4 of the cross-sectional area of ​​the inner tube of the backflush pipe.

[0010] As a third limitation of this utility model, the torsion spring and the torsion bar twist in opposite directions.

[0011] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0012] This utility model relates to an offline dust removal device for vacuum cleaning filter materials. Through the combination of a first baffle and a torsion spring, and with the help of a rotating ring, the first baffle and the first partition can form a complete circle covering the through hole, thereby isolating the offline dust removal unit from the operating dust collector without affecting the normal operation of the dust collector.

[0013] (2) The vacuum cleaning filter material offline cleaning device involved in this utility model, while the first partition and the first baffle cover the through hole, the torsion spring and the torsion rod are fixed on the same base plate and the torsion direction is opposite, so that the second partition and the second baffle of the back-blowing pipe overlap, so that the pipeline inside the back-blowing pipe is in an open state, and the back-blowing airflow enters the offline cleaning unit through the back-blowing pipe, blows the filter material sleeved outside the torsion spring, shakes off the dust attached to the filter material, and realizes the cleaning of each filter material sleeved in the offline cleaning unit.

[0014] In summary, this invention, on the one hand, eliminates the mutual constraints between filter cartridges, allowing each dust removal unit to operate independently without needing to shut down the dust removal equipment during cleaning and maintenance; on the other hand, based on the different dust accumulation conditions of the filter material in each dust removal unit, the opening and closing speeds of the baffles and partitions vary, ensuring full utilization of the filter material in each offline dust removal unit, thereby reducing the operating cost of the equipment and improving its practicality.

[0022] An embodiment of an offline dust removal device for vacuum cleaning filter materials

[0023] like Figs. 1 to 4 As shown, this embodiment relates to an offline dust removal device for vacuum cleaning filter materials, including multiple sets of offline dust removal units 2. Each offline dust removal unit 2 is hollow inside, with a through hole in the middle of the top, a connecting flange 1 on the outer side of the top, and a dust hopper 4 at the bottom. A backflush pipe 3 is inserted at the center of the through hole. Two first partitions 8 are symmetrically fixed on the outer wall of the backflush pipe 3 according to the central axis of the backflush pipe 3. The end of each first partition 8 away from the backflush pipe 3 is fixedly connected to the inner wall of the through hole. A rotating ring 10 is provided below the connection between the two first partitions 8 and the outer wall of the backflush pipe 3. Two first baffles 9 are symmetrically arranged on the rotating ring 10. Two second partitions 15 are provided inside the backflush pipe 3. The two second partitions 15 are symmetrically arranged according to the central axis of the backflush pipe 3. A connecting shaft 14 is provided at the connection between the two second partitions 15. A rotating shaft 13 is sleeved on the lower part of the connecting shaft 14. Two second baffles 16 are symmetrically arranged on the rotating shaft 13 according to its central axis.

[0024] Two first baffles 9 are respectively fixedly provided with torsion springs 5 ​​on their bottom surfaces. A base plate 6 is fixedly provided at the end of the torsion spring 5 away from the first baffle 9. An elastic torsion bar 7 is provided at the center of the base plate 6. The end of the elastic torsion bar 7 away from the center of the base plate is fixedly connected to the rotating shaft 13, and the torsion direction is opposite to that of the torsion spring 5.

[0025] Both first baffles 15 have a first stop block 11 fixedly installed on one side of their bottom edge; both second baffles 16 have a second stop block 12 installed on one side of their top edge. The two first stop blocks 11 and the two second stop blocks 12 are centrally symmetrical about the central axis of the backflush pipe 3.

[0026] Each of the first partition 8, the second partition 15, the first baffle 9, and the second baffle 16 is fan-shaped, wherein each of the first partition 8 and the first baffle 9 is 1 / 4 of the area of ​​the through hole, and each of the second partition 15 and the second baffle 16 is 1 / 4 of the cross-sectional area of ​​the inner tube of the backflush pipe 3.

[0027] When using this embodiment, the through hole at the top of the offline dust removal unit 2 is opened, the first baffle 9 is placed below the first partition 8, and the second baffle 16 and the second partition 15 inside the backflush pipe 3 form a complete circular baffle to close the backflush pipe 3. When the dust removal equipment with offline cleaning unit 2 is working, the filter material sleeved on the torsion spring 5 is contracted and twisted by the suction force of the dust removal equipment, which drives the torsion spring 5 to rotate. This causes the first baffle 9 fixed at the end of the torsion spring 5 to rotate out from under the first partition 8. At the same time, it drives the elastic torsion rod 7 fixed on the base plate 6. Since the torsion direction of the torsion rod and the torsion spring 5 is opposite, as the through hole gradually closes, the pipeline of the back-blowing pipe 3 gradually opens, so that the back-blowing air force of the back-blowing pipe 3 blows the filter material sleeved on the torsion spring 5. When the through hole is completely closed, the offline cleaning unit is isolated from the dust removal equipment, and the back-blowing pipe 3 is fully opened, so that the contracted filter material is reset, shaking off the dust covering the surface of the filter material, thus cleaning the filter material. During the reset process of the filter material, the second partition 15 and the second baffle 16 inside the back-blowing pipe 3 gradually unfold, closing the back-blowing pipe 3. The first partition 8 and the first baffle 9 in the through hole gradually overlap, so that the offline cleaning unit 2 is reconnected to the dust removal equipment.

[0028] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
