[0032] REFERENCE Figs. 1 to 3 A dust removal pipe, comprising: a pipe body 11, a front pipe opening (not shown in the figure) and a rear pipe opening (not shown in the figure) are arranged at both ends of the pipe body 11, and a plurality of first dust suction holes are arranged on the pipe wall of the pipe body 11;

[0033] An end cover 12 is arranged on the front pipe opening;

[0034] An installation part 13 is arranged on the rear pipe opening, used to connect the dust removal pipe and a negative pressure generating device.

[0035] In use, the installation part 13 is connected with the negative pressure generating device, the negative pressure generating device generates negative pressure, so that the dust outside the dust removal pipe is sucked into the dust removal pipe through the first dust suction hole, and the dust sucked into the dust removal pipe is sucked out of the dust removal pipe through the installation part 13, so as to reduce the content of dust in the manufacturing workshop and reduce the pollution of dust to the product;

[0036] The dust removal pipe in the embodiment has simple structure, simple manufacturing process, low cost, and is convenient for maintenance and replacement in later period.

[0037] Specifically, the first dust suction holes are uniformly distributed circumferentially along the pipe body 11, so as to ensure that the adsorption force received by the circumferential side of the pipe body 11 is consistent.

[0038] As an example, the negative pressure generating device is a vacuum pump.

[0039] Specifically, the end cover 12 is detachably connected with the pipe body 11, facilitating cleaning of the pipe body 11.

[0040] In one embodiment, the end cover 12 is provided with a plurality of second dust suction holes. Dust can be sucked into the pipe body 11 from one side of the end cover 12, further enriching the dust suction site, increasing the dust suction area, and improving the dust suction efficiency.

[0041] In one embodiment, the mounting portion 13 includes a transition pipe 131 connected with the rear pipe opening and a connecting pipe 132 connected with the transition pipe 131, and the connecting pipe 132 is connected with the negative pressure generating device. When dust is sucked into the pipe body 11, the dust passes through the transition pipe 131 and the connecting pipe 132 in sequence, and the shape of the transition pipe 131 can be set to reduce dust accumulation and reduce air resistance.

[0042] As an example, the transition pipe 131 can be conical or pyramidal.

[0043] Specifically, the transition pipe 131 is frustoconical, the transition pipe 131 is coaxially arranged with the connecting pipe 132, and the diameter of the pipe opening of the connecting pipe 132 is smaller than the diameter of the rear pipe opening. Along the flow direction of the dust, the cross-sectional area of the transition pipe 131 is decreasing. Compared with the prior art in which the transition pipe 131 is straight, the frustoconical transition pipe 131 can avoid the dead angle in the form of a right angle, avoid the accumulation of dust in the transition pipe 131, and help to optimize the air flow, reduce the resistance of the air flow in the pipeline, and improve the dust suction efficiency.

[0044] In one embodiment, the pipe body 11 is cylindrical. In terms of manufacturing, the cylindrical shape is simple to process and low in cost, and the materials and sizes of the pipe are various, which can be selected according to the actual space inside the dust removal device.

[0045] A dust removal device includes a rack 2, and a plurality of dust removal pipes 1 according to any one of the above embodiments are arranged in the rack 2. The dust removal pipe 1 can be arranged on the belt conveying path of the dust removal device. For example, in the process of manufacturing lithium battery pole pieces, a lot of fine powder is adhered to the surface of the pole piece material after the coated pole piece is compacted. During the belt conveying and winding process, the dust will be adhered to the surface of the pole piece, which will affect the quality of the battery. By arranging the dust removal pipe 1 on the belt conveying path of the pole piece, the dust generated during the belt conveying process of the pole piece can be adsorbed, and the dust adhered to the surface of the pole piece is reduced, which affects the quality of the pole piece.

[0046] In one embodiment, the rack 2 has an internal space 21 and a top dust suction unit 4, the dust removal pipe 1 is arranged in the internal space 21, and the top dust suction unit 4 is arranged at the top of the rack 2 and above the dust removal pipe 1. The top dust suction unit 4 is used to suck the dust in the internal space 21, and assists the dust removal pipe 1 to make a cleaner internal space 21.

[0047] Specifically, the internal space 21 is provided with a support plate 211, and the fixing member 3 is detachably connected to the support plate 211. The fixing member 3 is detachably connected with the dust removal pipe 1, and is used to fix the dust removal pipe 1 on the support plate 211, so as to fix the position of the dust removal pipe 1 in the internal space 21, and avoid the deviation of the dust removal pipe 1 when the material is conveyed in the internal space 21.

[0048] More specifically, the fixing member 3 includes an upper fixing member 31 and a lower fixing member 32, and the upper fixing member 31 and the lower fixing member 32 jointly enclose the mounting portion 13 of the dust removal pipe 1, so as to fix the dust removal pipe 1 on the support plate 211.

[0049] During installation, the upper fixing member 31 and the lower fixing member 32 are locked with each other by screws, and the upper fixing member 31 and the lower fixing member 32 are locked on the support plate 211.

[0050] Specifically, the upper fixing member 31 and the lower fixing member 32 are detachably connected.

[0051] More specifically, the support plate 211 is provided with a plurality of mounting holes (not shown in the figure), and part of the mounting portion 13 passes through the mounting hole to be fixed on the support plate 211.

[0052] More specifically, when producing dust removal pipes of different sizes, the sizes of the mounting portions 13 can all be set to be fixed and consistent, so as to match the mounting holes on the support plate 211. By adjusting the sizes of the pipe body 11 and the end cover 12 during production, the pipe body 11 of a suitable size can be made according to the requirements of the internal space 21.

[0053] The above is a specific description of the preferred embodiment of the utility model, but the utility model creation is not limited to the above-mentioned embodiment. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
