Description

Technical Field

[0001] This invention relates to the field of explosion-proof industrial dust collectors, and more particularly to an explosion-proof industrial dust collector. Background Technology

[0002] Lithium-ion batteries are manufactured by winding or stacking positive and negative electrode sheets into the required cells, followed by processes such as electrolyte injection. During the manufacturing process of the electrode sheets, laser die-cutting equipment is used to cut the electrode sheets. Dust is generated during the cutting process. If this dust adheres to the electrode sheet roll and is carried into subsequent processes, or even gets caught inside the battery, it can easily puncture the separator inside the cell, causing a micro-short circuit or even a battery explosion.

[0003] Current laser cutting is mainly performed on a bottom mold, which is equipped with a dust suction port. Dust is removed using negative pressure. However, with long-term use, the filter cartridges used to filter dust in dust removal equipment will become clogged, resulting in poor air permeability and filtration. In existing technologies, although some back-blowing devices are used to back-blow and unclog the filter cartridges, the air curtain blown out by the back-blowing device has a single direction and cannot back-blow the entire filtration side of the filter cartridge. Therefore, an explosion-proof industrial dust collector is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes an explosion-proof industrial dust collector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an explosion-proof industrial dust collector, comprising a dust collection box, wherein the dust collection box is provided with a first chamber, a second chamber, and a third chamber arranged sequentially from bottom to top. A connecting pipe is connected to the first chamber. The first chamber contains a plurality of filter cartridges arranged in a rectangular pattern. The first chamber and the second chamber are connected through the plurality of filter cartridges. The third chamber contains a negative pressure fan, the air inlet of which is connected to the second chamber. A connecting pipe is fixedly installed on the outside of the dust collection box. A filter mechanism is fixedly installed on the top of the dust collection box. The third chamber is connected to the outside through the filter mechanism. The second chamber contains an air supply mechanism, on which a plurality of air jets are installed. The plurality of air jets are respectively located directly above the corresponding filter cartridges and coaxially arranged with the corresponding filter cartridges. The air supply mechanism can backflush and unclog the corresponding filter cartridges through the plurality of air jets.

[0006] Preferably, one side of the first chamber is provided with a first door and a second door, and the bottom of the first chamber is provided with a dust hopper. The air jet can be extracted from the first chamber by opening the first door. Multiple triangular strips are fixedly installed on the inner wall of the first chamber in a linear distribution, and the multiple triangular strips are all located below the filter cylinder.

[0007] Furthermore, by setting triangular strips, the amount of dust rising from the ash hopper can be reduced when the filter cartridge is backflushed and cleared.

[0008] Preferably, the filtration mechanism includes a rectangular box fixedly installed on the top of the dust collection box, the bottom of the rectangular box is open and connected to the three chambers, the top of the rectangular box is provided with an exhaust port, and a filter element is detachably installed inside the rectangular box.

[0009] Preferably, the air supply mechanism includes a compressed air tank fixedly installed on the inner wall of the bottom of the second chamber. The compressed air tank is provided with multiple conduits, each of which is fixedly equipped with a pulse controller. Multiple air jets are respectively fixedly connected to the corresponding pulse controllers.

[0010] Preferably, the jet component includes a fixed tube fixedly connected to a pulse controller, the bottom end of the fixed tube is provided with a cylinder, and a plurality of connecting plates arranged in a circumferential array are fixedly installed at the bottom of the cylinder, and the bottom of the plurality of connecting plates is fixedly installed with the same conical cylinder.

[0011] Preferably, the inner wall of the air outlet has multiple air outlets arranged in a circular array, and the bottom inner wall of the air outlet has a guide slope.

[0012] Preferably, a plurality of connecting plates 2 arranged in a circumferential array are fixedly installed on the inner wall of the conical cylinder 1, and the same conical cylinder 2 is fixedly installed at the bottom of the plurality of connecting plates 2. A plurality of connecting plates 3 arranged in a circumferential array are fixedly installed on the inner wall of the conical cylinder 2, and the same conical cylinder 3 is fixedly installed at the bottom of the plurality of connecting plates 3. A plurality of connecting plates 4 arranged in a circumferential array are fixedly installed on the inner wall of the conical cylinder 3, and the same conical column is fixedly installed on the side of the plurality of connecting plates 4 that are close to each other.

[0013] Preferably, a backflow prevention mechanism is fixedly installed on the inner wall of the first chamber. The backflow prevention mechanism in the open state allows the connecting pipe to be connected to the first chamber. The backflow prevention mechanism includes two vertical plates fixedly connected to the inner wall of the first chamber, two horizontal plates fixedly installed between the two vertical plates, and a conical plate fixedly installed between the two horizontal plates. Valve plates are provided on both sides of the conical plate, and the valve plates are connected to the conical plate by two spring hinges.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up jet components, the present invention enables the compressed air discharged from the air supply mechanism to form a multi-layered cone-shaped back-blowing air curtain inside the filter cylinder. These cone-shaped back-blowing air curtains can back-blow and unclog at different height positions inside the filter cylinder.

[0016] 2. By installing a backflow check mechanism between the connecting pipe and chamber 1, the backflow check mechanism will be in the open state when absorbing and filtering dust. The open state of the backflow check mechanism can prevent dust from directly impacting the filter cartridge, thus protecting the filter cartridge. When back-flushing and unblocking the filter cartridge, the backflow check mechanism will be in the closed state, ensuring that the dust blown off the filter cartridge will not be discharged through the connecting pipe.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please refer to Figures 1-8 This invention provides a technical solution: an explosion-proof industrial dust collector, including a dust collection box 1. The dust collection box 1 contains, from bottom to top, three chambers: a first chamber 11, a second chamber 12, and a third chamber 13. A connecting pipe 2 connects to the first chamber 11. The first chamber 11 contains multiple filter cartridges 4 arranged in a rectangular pattern. The first chamber 11 and the second chamber 12 are connected through the multiple filter cartridges 4. The third chamber 13 contains a negative pressure fan 7, the air inlet of which is connected to the second chamber 12. The connecting pipe 2 is fixedly installed on the outside of the dust collection box 1. A filter mechanism 8 is fixedly installed on the top of the dust collection box 1. The third chamber 13 is connected to the outside through the filter mechanism 8. The second chamber 12 contains an air supply mechanism 5, on which multiple air jets 6 are installed. The multiple air jets 6 are located directly above and coaxially arranged with the corresponding filter cartridges 4. The air supply mechanism 5 can back-blow and unclog the corresponding filter cartridges 4 through the multiple air jets 6.

[0028] One side of the chamber 11 is provided with a first door 14 and a second door 15. The bottom of the chamber 11 is provided with a dust collection hopper 16. The air jet 6 can be extracted from the chamber 11 through the opened door 14. Multiple triangular strips 17 are fixedly installed on the inner wall of the chamber 11 in a linear distribution. All the triangular strips 17 are located below the filter cylinder 4.

[0029] Furthermore, opening the second door 15 makes it easier for staff to replace or manually clean the filter cartridge 4.

[0030] The filter mechanism 8 includes a rectangular box 81 fixedly installed on the top of the dust collection box 1. The bottom of the rectangular box 81 is open and connected to the chamber 13. The top of the rectangular box 81 is provided with an exhaust port 82. A filter element 83 is detachably installed inside the rectangular box 81.

[0031] Furthermore, fine dust particles that cannot be filtered by filter cartridge 4 can be filtered by filter element 83 to ensure that the air discharged from exhaust port 82 does not contain harmful dust. Subsequently, filter element 83 only needs to be removed from rectangular box 81 periodically for cleaning, unclogging or replacement.

[0032] The gas supply mechanism 5 includes a compressed air tank 51 fixedly installed on the inner wall of the bottom of the second chamber 12. The compressed air tank 51 is provided with multiple conduits 52, and each of the multiple conduits 52 is fixedly installed with a pulse controller 53. Multiple jet components 6 are respectively fixedly connected to the corresponding pulse controller 53.

[0033] The jet component 6 includes a fixed tube 61 fixedly connected to the pulse controller 53. The bottom end of the fixed tube 61 is provided with a cylinder 62. Multiple connecting plates 621 arranged in a circumferential array are fixedly installed at the bottom of the cylinder 62. The bottom of the multiple connecting plates 621 is fixedly installed with the same conical cylinder 64.

[0034] Multiple air outlets 63 are arranged in a circular array on the inner wall of the air outlet 63, and a guide slope 631 is provided on the bottom inner wall of the air outlet 63.

[0035] Multiple connecting plates 65 arranged in a circular array are fixedly installed on the inner wall of the conical cylinder 64. The bottom of the multiple connecting plates 65 is fixedly installed on the same conical cylinder 66. Multiple connecting plates 67 arranged in a circular array are fixedly installed on the inner wall of the conical cylinder 66. The bottom of the multiple connecting plates 67 is fixedly installed on the same conical cylinder 68. Multiple connecting plates 69 arranged in a circular array are fixedly installed on the inner wall of the conical cylinder 68. The same conical column 610 is fixedly installed on the side of the multiple connecting plates 69 that are close to each other.

[0036] Furthermore, when the pulse controller 53 is turned on, the compressed air in the compressed air tank 51 is discharged into the fixed pipe 61 through the conduit 52 and sprayed downwards. A portion of the compressed air flowing through the cylinder 62 will be sprayed out through multiple air outlets 63. Guided by the guide slope 631, this portion of compressed air will be sprayed downwards and form a diagonally sprayed back-blowing air jet.

[0037] Another part of the compressed air is discharged through the bottom opening of the cylinder 62. Part of this compressed air will hit the top of the conical cylinder 64, and the other part will enter the interior of the conical cylinder 64 through the top opening of the conical cylinder 64. The compressed air hitting the top of the conical cylinder 64 will form the first layer of downward-spraying cone-shaped back-blowing air curtain.

[0038] Part of the compressed air entering the conical cylinder 64 will impact the top of the conical cylinder 66, while the other part will enter the conical cylinder 66 through the top opening. The compressed air impacting the top of the conical cylinder 66 will form a second layer of downward-spraying cone-shaped back-blowing air curtain.

[0039] Part of the compressed air entering the second cone 66 will impact the top of the third cone 68, and the other part will enter the third cone 68 through the top opening. The compressed air impacting the top of the third cone 68 will form a third layer of downward-spraying cone-shaped back-blowing air curtain.

[0040] The remaining compressed air entering the conical cylinder 68 will impact the conical surface of the conical column 610 to form a fourth layer of downward-spraying conical back-blowing air curtain;

[0041] Therefore, as the compressed air discharged from the duct 52 flows through the jet 6, it will form a multi-layered cone-shaped back-blowing air curtain. These cone-shaped back-blowing air curtains can back-blow and clear the air at different heights inside the filter cylinder 4.

[0042] A backflow prevention mechanism 3 is fixedly installed on the inner wall of chamber 11. When the backflow prevention mechanism 3 is in the open state, the connecting pipe 2 can be connected to chamber 11. The backflow prevention mechanism 3 includes two vertical plates 31 fixedly connected to the inner wall of chamber 11. Two horizontal plates 32 are fixedly installed between the two vertical plates 31. A conical plate 33 is fixedly installed between the two horizontal plates 32. A valve plate 34 is provided on both sides of the conical plate 33. The valve plate 34 and the conical plate 33 are connected by two spring hinges 35.

[0043] Furthermore, when the negative pressure fan 7 is in the on state, the interior of chamber 11 will be in a negative pressure state. At this time, when the external air flows into chamber 11 through the connecting pipe 2, the air will push the two valve plates 34, causing the two valve plates 34 to rotate around the corresponding spring hinge 35 and separate from the corresponding valve plate 34. Then, the external air can enter the chamber 11 through the channel between the valve plate 34 and the vertical plate 31. And through the obstruction of the conical plate 33 and the two valve plates 34, the airflow carrying dust is guided to both sides, avoiding the airflow carrying dust from directly hitting the filter cartridge 4, thus providing a certain degree of protection for the filter cartridge 4.

[0044] Furthermore, when the negative pressure fan 7 is in the closed state, the two valve plates 34 will abut against the corresponding vertical plates 31 respectively. At this time, the backflow prevention mechanism 3 in the closed state prevents the connecting pipe 2 from being connected to the chamber 11. Then, when the air supply mechanism 5 and multiple air jets 6 are used to back-blown and unclog the corresponding filter cartridge 4, it ensures that the dust blown off the filter cartridge 4 will not be discharged through the connecting pipe 2.

[0045] In this embodiment: the dust suction pipe is connected to the connecting pipe 2. When working, the negative pressure fan 7 is started. The dust flows through the dust suction pipe, through the connecting pipe 2, and through the opened backflow check mechanism 3 into the first chamber 11. After being filtered by multiple filter cartridges 4, most of the dust is filtered by the filter cartridges 4. A small part of the fine dust passes through the filter cartridges 4 and enters the second chamber 12, and then flows through the negative pressure fan 7 into the third chamber 13. After being filtered by the filter mechanism 8, the small part of the dust that passed through the filter cartridges 4 will be completely filtered.

[0046] When the filter cartridge 4 needs to be cleaned after long-term operation, first turn off the negative pressure fan 7. As the negative pressure fan 7 is turned off, the backflow prevention mechanism 3 is also immediately closed, so that the connecting pipe 2 is not connected to the chamber 11. Then, the compressed air in the compressed air tank 51 is released through the pulse controller 53. The compressed air in the compressed air tank 51 flows through the duct 52 and is discharged through the jet 6. The compressed air discharged from the jet 6 forms a multi-layer cone-shaped air curtain. The multi-layer cone-shaped air curtain can back-blown and clean the inside of the filter cartridge 4 from top to bottom. The dust blown down from the filter cartridge 4 will fall into the dust collection hopper 16. Afterwards, you only need to open the hopper door 14 periodically to remove the dust collection hopper 16 from the chamber 11 for cleaning.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
