Dust removal device and self-cleaning method thereof

technical field

The present application relates to the technical field of dust removal, and in particular, to a dust removal device and a self-cleaning method thereof.

Background technique

In the forming process of laser cutting pole tabs of lithium-ion battery pole pieces, the treatment of dust generated during laser cutting pole tabs has always been a difficult problem; the dust generated by laser cutting pole tabs will affect the quality of the pole pieces and cause trouble to the subsequent process. There are potential safety hazards for the production and use of the entire battery; it will pollute the air. If the dust generated in the production process is not cleaned up, it will float directly into the air and pollute the air; it will reduce the service life of the equipment, and the generated dust will directly enter the equipment bearings.

This embodiment provides a dust removal device 10 , which can solve the problem in the prior art that when a negative pressure is used for dust removal, the dust removal pipe is easily blocked by dust, making it difficult to clean and maintain.

Please refer to FIG. 1 , which shows the specific structure of the dust removal device 10 in this embodiment.

The dust removal device 10 includes a main pipe 11 and a plurality of branch pipes 12 . One end of the main pipe 11 is used for connecting the negative pressure device. One end of each branch pipe 12 is connected to the main pipe 11, and the other end is used to connect the equipment dust removal pipe. Each branch pipe 12 is provided with a valve 13 .

Among them, in the technical solution described above, a dust removal device 10 capable of vacuuming and self-cleaning with negative pressure is provided. The dust removal device 10 includes a main pipeline 11 and a plurality of branch pipelines 12. One end of the main pipeline 11 is used to connect the negative pressure Each branch pipe 12 is used to connect the equipment dust removal pipe, so as to act on the position of the manufacturing processing equipment that needs dust removal. The negative pressure device generates negative pressure, so that each branch pipe 12 generates negative pressure, so as to complete the dust removal of the manufacturing and processing equipment. After a long time of negative pressure dust removal, the power of the negative pressure device will increase, or the dust removal efficiency of negative pressure dust removal is not high. The inventor found that the problem is that dust will accumulate in the dust removal pipe, which leads to the reduction of dust removal efficiency. In order to ensure the dust removal efficiency, the dust in the pipeline needs to be treated immediately. For this reason, the inventor designed the dust removal device 10 described above, which can clean the pipeline without disassembling the dust removal pipeline: each branch pipeline 12 is provided with The valve 13, the opening and closing of the valve 13 controls the conduction or closing of the branch pipe 12. When a branch pipe 12 (and the corresponding equipment dust removal pipe) needs to be cleaned, the valve 13 of the branch pipe 12 to be cleaned is opened, Close the remaining branch pipes 12.

Since the angle of the valve plate 131 in the electric valve is controlled by the motor 130, when actually cleaning the branch pipe 12, the rotation angle of the valve plate 131 can also be controlled to control the magnitude of the negative pressure. For example, when a certain branch pipe 12 (and its corresponding equipment dust removal pipe) needs to be cleaned, the motor 130 of the electric valve of the branch pipe 12 to be cleaned is controlled, so that the valve plate 131 rotates and the remaining branch pipes 12 are closed. , the negative pressure in the main pipe 11 will act on the branch pipe 12 to be cleaned, and the negative pressure in the branch pipe 12 to be cleaned will fluctuate according to the rotation of the valve plate 131, so that the fluctuating negative pressure in the branch pipe 12 acts on The dust accumulated in the tube loosens the dust, so that it can be smoothly extracted and self-cleaning is completed.
