Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof industrial dust collectors, and in particular to an explosion-proof industrial dust collector. Background Art

[0002] Lithium-ion batteries are batteries made by winding or stacking positive and negative electrodes into the required battery cells and then injecting electrolytes. In the manufacturing process of the electrode sheets, laser die-cutting equipment is required to cut the electrode sheets, which will generate dust. If the dust adheres to the electrode sheet coil and is carried into the subsequent process, or even rolled into the battery, it is easy to pierce the diaphragm in the battery cell, causing a micro short circuit in the battery or even an explosion.

[0003] The existing laser cutting is mainly carried out on the bottom mold, which is provided with a dust suction port to remove dust by negative pressure. However, after long-term use, the filter cartridge used to filter dust on the dust removal equipment will be clogged, resulting in poor air permeability and filtration. In the prior art, although some back-blowing devices are used to back-blow and dredge the filter cartridge, the wind curtain blown out by the back-blowing device has a single direction and cannot back-blow the entire filtering side of the filter cartridge. For this reason, an explosion-proof industrial dust collector is proposed. Summary of the invention

[0007] Furthermore, by setting the triangular strip, it is possible to reduce the dust rising in the ash hopper when backwashing and dredging the filter cartridge.

[0008] Preferably, the filtering mechanism includes a rectangular box fixedly installed on the top of the dust removal box. The bottom of the rectangular box is open and communicates with chamber three.

A plurality of conduits are provided on the compressed air tank, and pulse controllers are fixedly installed on the plurality of conduits. A plurality of jetting members are fixedly connected to the corresponding pulse controllers respectively.

[0026] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 8 , the present invention provides a technical solution: an explosion-proof industrial dust collector, including a dust removal box 1. Inside the dust removal box 1, a chamber one 11, a chamber two 12 and a chamber three 13 are sequentially arranged from bottom to top. A connecting pipe 2 is communicated with the chamber one 11. Inside the chamber one 11, a plurality of filter cartridges 4 distributed in a rectangular shape are provided. The chamber one 11 and the chamber two 12 are communicated through a plurality of filter cartridges 4. Inside the chamber three 13, a negative pressure fan 7 is provided. The air inlet of the negative pressure fan 7 is communicated with the chamber two 12. The connecting pipe 2 is fixedly installed on the outside of the dust removal box 1. The filter mechanism 8 is fixedly installed on the top of the dust removal box 1. The chamber three 13 is communicated with the outside through the filter mechanism 8. Inside the chamber two 12, an air supply mechanism 5 is provided. A plurality of jet components 6 are installed on the air supply mechanism 5. The plurality of jet components 6 are respectively located directly above the corresponding filter cartridges 4 and are coaxially arranged with the corresponding filter cartridges 4. The air supply mechanism 5 can perform back blowing and dredging on the corresponding filter cartridges 4 through the plurality of jet components 6.

[0028] On one side of the chamber one 11, a warehouse door one 14 and a warehouse door two 15 are provided. At the bottom of the chamber one 11, an ash hopper 16 is provided. The jet component 6 can be drawn out of the chamber one 11 through the opened warehouse door one 14. A plurality of triangular strips 17 distributed linearly are fixedly installed on the inner wall of the chamber one 11. The plurality of triangular strips 17 are all located below the filter cartridges 4.

[0029] Furthermore, by opening the warehouse door two 15, it is convenient for the staff to replace or manually clean the filter cartridges 4.

[0030] The filtering mechanism 8 includes a rectangular box 81 fixedly installed at the top of the dust removal box 1. The bottom of the rectangular box 81 is open and communicates with the third chamber 13. An exhaust port 82 is provided at the top of the rectangular box 81, and a filter element 83 is detachably installed in the rectangular box 81.

[0031] Furthermore, for some fine dust that cannot be filtered by the filter cartridges 4, it can be filtered by the filter element 83 to ensure that the air discharged from the exhaust port 82 does not contain harmful dust. Subsequently, the filter element 83 only needs to be regularly taken out of the rectangular box 81 for cleaning, dredging or replacement.

[0032] The air supply mechanism 5 includes a compressed air tank 51 fixedly installed on the inner wall of the bottom of the second chamber 12. A plurality of conduits 52 are provided on the compressed air tank 51, and a pulse controller 53 is fixedly installed on each of the plurality of conduits 52. A plurality of jetting members 6 are fixedly connected to the corresponding pulse controllers 53 respectively.

[0033] The jetting member 6 includes a fixed pipe 61 fixedly connected to the pulse controller 53. A cylinder 62 is provided at the bottom end of the fixed pipe 61. At the bottom of the cylinder 62, a plurality of first connecting plates 621 distributed in a circumferential array are fixedly installed, and a same conical cylinder 64 is fixedly installed at the bottoms of the plurality of first connecting plates 621.

[0034] A plurality of air outlets 63 are formed in the inner wall of the air outlet 63 and are distributed in a circumferential array. A flow guiding inclined surface 631 is provided on the inner wall of the bottom of the air outlet 63.

[0035] A plurality of second connecting plates 65 distributed in a circumferential array are fixedly installed on the inner wall of the conical cylinder 64. A same conical cylinder 66 is fixedly installed at the bottoms of the plurality of second connecting plates 65. A plurality of third connecting plates 67 distributed in a circumferential array are fixedly installed on the inner wall of the conical cylinder 66. A same conical cylinder 68 is fixedly installed at the bottoms of the plurality of third connecting plates 67. A plurality of fourth connecting plates 69 distributed in a circumferential array are fixedly installed on the inner wall of the conical cylinder 68. A same conical column 610 is fixedly installed on the side where the plurality of fourth connecting plates 69 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 downward. A part of the compressed air flowing through the cylinder 62 will be sprayed out through the plurality of air outlets 63. Guided by the flow guiding inclined surface 631, this part of the compressed air will be sprayed downward to form an obliquely sprayed reverse blowing beam;

[0037] Another part of the compressed air is discharged through the opening at the bottom of the cylinder 62. A part of this part of the compressed air will impact on the top of the first conical cylinder 64, and another part will enter the inside of the first conical cylinder 64 through the top opening of the first conical cylinder 64. The compressed air impacting on the top of the first conical cylinder 64 will form the first layer of downwardly ejected conical reverse blowing curtain;

[0038] A part of the compressed air entering the inside of the first conical cylinder 64 will impact on the top of the second conical cylinder 66, and another part will enter the second conical cylinder 66 through the top opening of the second conical cylinder 66. The compressed air impacting on the top of the second conical cylinder 66 will form the second layer of downwardly ejected conical reverse blowing curtain;

[0039] A part of the compressed air entering the inside of the second conical cylinder 66 will impact on the top of the third conical cylinder 68, and another part will enter the third conical cylinder 68 through the top opening of the third conical cylinder 68. The compressed air impacting on the top of the third conical cylinder 68 will form the third layer of downwardly ejected conical reverse blowing curtain;

[0040] The remaining compressed air entering the third conical cylinder 68 impacts on the conical surface of the conical column 610 to form the fourth layer of downwardly ejected conical reverse blowing curtain;

[0041] Therefore, when the compressed air discharged from the conduit 52 flows through the jet member 6, multiple layers of conical reverse blowing curtains will be formed. These conical reverse blowing curtains can perform reverse blowing and dredging at different height positions inside the filter cartridge 4.

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

[0043] Furthermore, when the negative pressure fan 7 is in the open state, the inside of the first chamber 11 will be in a negative pressure state. At this time, when external air flows into the first 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 hinges 35 and separate from the corresponding valve plates 34. Thus, the external air can enter the first chamber 11 through the channels between the valve plates 34 and the vertical plates 31. And through the blocking 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 directly impacting on the filter cartridge 4 and playing a certain protective role for the filter cartridge 4;

[0044] And when the negative pressure fan 7 is in the closed state, the two valve plates 34 will respectively abut against the corresponding vertical plates 31. At this time, the check and backflow prevention mechanism 3 in the closed state makes the connecting pipe 2 not communicate with the first chamber 11. Then, when the air supply mechanism 5 and multiple jet parts 6 are used to blow back and dredge the corresponding filter cartridges 4, it is ensured that the dust blown off from the filter cartridges 4 will not be discharged through the connecting pipe 2.

[0045] In this embodiment: The pipeline used for dust suction is connected to the connecting pipe 2. During operation, the negative pressure fan 7 is started, and the dust flows through the connecting pipe 2 through the dust suction pipeline and enters the first chamber 11 through the opened check and backflow prevention mechanism 3. After being filtered by multiple filter cartridges 4, most of the dust is filtered by the filter cartridges 4, and 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 and enters the third chamber 13. After that, through the filtration of the filtration mechanism 8, a small part of the dust passing through the filter cartridges 4 will be completely filtered;

[0046] When the filter cartridges 4 need to be dredged and cleaned after long-term operation, first, the negative pressure fan 7 is turned off. As the negative pressure fan 7 is turned off, the check and backflow prevention mechanism 3 also closes immediately, making the connecting pipe 2 not communicate with the first chamber 11. Then, the pulse controller 53 releases the compressed air in the compressed air tank 51. The compressed air in the compressed air tank 51 flows through the conduit 52 and is discharged through the jet part 6. The compressed air discharged from the jet part 6 forms a multi-layer conical curtain of air. The multi-layer conical curtain of air can blow back and dredge the inside of the filter cartridges 4 from top to bottom. The dust blown back from the filter cartridges 4 will fall into the ash hopper 16. Subsequently, only need to regularly open the first chamber door 14 to take out the ash hopper 16 from the first chamber 11 for cleaning.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
