Description

Technical Field

[0001] The utility model relates to the technical field of feeding dust removal, in particular to a dust removal device used in a slurry feeding area of ​​the lithium battery industry. Background Art

[0002] The dust removal equipment in the slurry feeding area of ​​the lithium battery industry is used to remove dust and particulate matter generated in the slurry feeding area. The slurry feeding area is the area where the positive and negative slurries of lithium batteries are prepared. Usually, a large amount of fine particles and dust are generated. By inhaling the air in the slurry feeding area, the particles and dust in it are filtered out to keep the air clean, improve the indoor air quality, and reduce the impact of dust on employee health. At the same time, it can also protect the normal operation of production equipment and avoid dust corrosion and blockage of equipment. The dust removal equipment in the slurry feeding area is an indispensable environmental protection equipment.

[0003] In the prior art, the positive and negative electrode slurries of lithium batteries are usually composed of fine particles of powder, which are easily affected by air flow and dispersed. The positive and negative electrode slurries of lithium batteries are loaded and transported to the loading rack body, and then the slurries are centrally transported to subsequent operations through the loading rack body. However, in the process of loading the slurry, due to the properties of the slurry and improper operation, the slurry is very easy to generate dust, and some dust escapes upward from the opening of the loading rack body. The escaped dust cannot be captured in time, which will eventually affect the dust removal effect in the room. Utility Model Content

[0004] In order to solve the above technical problems, the utility model utilizes dust hood 1 and dust hood 2 to be connected to form a common air extraction and dust suction for the dust area, so as to collect powder dust to the maximum extent. The specific technical scheme is as follows:

[0005] A dust removal device for a slurry feeding area in the lithium battery industry comprises a loading rack, one side of which is provided with an opening for feeding, and the slurry fed into the loading rack is dusted upward from the opening to form a dust emission area; a dust removal device, which extracts air and collects dust from the dust emission area of ​​the loading rack; and a dust collection device, which collects dust from the dust removal device.

[0006] Preferably, the dust removal device comprises at least one dust removal hood arranged on the loading rack.

[0007] Preferably, the dust removal equipment comprises dust hood 1 and dust hood 2 located at the opening of the loading rack, and an air inlet main duct is fixedly installed between the dust hood 1, the dust hood 2 and the loading rack and the dust collecting equipment.

[0008] Preferably, the second dust hood is rotatably connected to the loading rack and is opened or closed with the loading rack. The first dust hood is adjacent to the second dust hood in an open state and they jointly extract air and collect dust from the dust emission area.

[0009] Preferably, the second dust cover comprises a second shell, a second support member and a second baffle which are fixed to each other.

[0010] Preferably, the dust cover 1 includes a shell 1, a support 1 and a baffle 1 which are fixed to each other.

[0011] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0012] By arranging dust hood 1 and dust hood 2 located at the opening of the loading rack, the slurry collides with the side wall of the loading rack to generate dust, and the dust escapes upward from the opening of the loading rack. After the dust hood 2 is opened, it is adjacent to the dust hood 1. The dust hood 1 and the dust hood 2 generate negative pressure suction, and jointly exhaust air and dust from the interior of the loading rack and the dust escape area of ​​the opening. The dust flows into the dust collecting equipment through the main air inlet duct. The dust collecting equipment collects the dust, expands the dust collection range, and has a more complete dust collection effect when dust escapes during the loading process.

[0013] Both the dust hood 1 and the dust hood 2 are provided with baffles, which can reduce the cross-sectional area of ​​the dust hood, thereby increasing the wind speed of the dust hood cross section and improving the dust collection capacity.

[0014] The dust hood 2 can rotate with the loading rack. After the dust hood 2 is opened, the loading rack can be fed. After the feeding is completed, the dust hood 2 is closed to close the feeding port of the feeding equipment to prevent powder from escaping into the workshop during the operation of the slurry feeding equipment.

[0021] If three dust hoods are used, on the basis of dust hood 1 6 and dust hood 2 5, dust hood 3 10 is installed on the top of the loading rack 7, and the end of the air inlet main duct 4 away from the dust collecting device 3 is fixed and connected to the dust hood 3 10, and the end of the air inlet main duct 4 away from the dust collecting device 3 is respectively provided with a branch pipe 12 connected to the dust hood 1 6 and a branch pipe 2 13 connected to the dust hood 2 5, and a hose 11 is provided between the branch pipe 12 and the branch pipe 2 13 and the dust hood 1 6 and the dust hood 2 5, wherein the hose 11 is used to improve the flexibility of the movement of the dust hood 1 6 and the dust hood 2 5, and the dust hood 1 6 and the branch pipe 1 12 are connected to the branch pipe 1 12. A support component 14 is fixedly installed between them. The support component 14 can be a telescopic rod, a pull rod or a telescopic cylinder, which is used to pull and limit the dust hood 6. Secondly, the dust hood 6 can be moved in different directions through the hose 11, which is convenient for adjustment; a support rod 9 is arranged between the dust hood 2 5 and the loading rack 7. The support rod 9 is used to limit the dust hood 2 5 after it is opened to ensure that the opening of the dust hood 2 5 and the loading rack 7 are in an open state.
