Description

Technical Field

[0001] This utility model relates to the field of lithium battery anode material production technology, specifically a micro-negative pressure dust removal device. Background Technology

[0002] In the processing of graphite powder, the existing furnace loading process involves loading a layer of powder, then manually compacting it, and finally placing a guide column to conduct electricity and generate heat. During the feeding process, a certain amount of powder is generated outside the furnace, which pollutes the environment and affects the utilization rate of the product. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a micro negative pressure dust removal device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a micro negative pressure dust removal device, comprising a movable platform installed on the edge of the furnace body, a manifold arranged horizontally on the movable platform, a dust suction hole at the bottom of the manifold, the dust suction hole being located above the furnace chamber, a filter element installed at the dust suction hole, and an exhaust fan installed at the top of the manifold.

[0005] As a preferred embodiment of this utility model, the number of dust suction holes is not less than three and they are arranged at equal intervals at the bottom of the manifold.

[0006] As a preferred embodiment of this utility model, a backflush airbag is provided outside the filter element, and the exhaust port of the backflush airbag is connected to the interior of the filter element through a pipe.

[0007] As a preferred technical solution of this utility model, the filter element is provided with a dust removal cover, which is fixed on the manifold, and the area covered by the dust removal cover is a micro-negative pressure area.

[0008] As a preferred embodiment of this utility model, the mobile platform includes a drive assembly and a matching guide rail, which is installed on the top edge of the furnace body.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This micro negative pressure dust removal device is used in conjunction with feeding equipment to recover the powder that is thrown out during the feeding process. By creating a micro negative pressure environment, the amount of powder thrown out in the external air can be effectively reduced. Combined with the absorption of powder by the filter element and the back-blowing airflow, the powder is recycled and reused, creating a better working environment and improving the utilization rate of the product.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a micro-negative pressure dust removal device, including a movable platform 8 installed on the edge of the furnace body 1. The movable platform 8 includes a drive component and a matching guide rail. The guide rail is installed on the top edge of the furnace body 1. A manifold 3 is arranged horizontally on the movable platform 8. A dust suction hole 4 is provided at the bottom of the manifold 3. The number of dust suction holes 4 is not less than three and they are arranged at equal intervals at the bottom of the manifold 3 to form a strip-shaped area of ​​dust suction micro-negative pressure space. The dust suction hole 4 is located above the furnace chamber 2. A filter element 6 is installed at the dust suction hole 4. A back-blowing air bag 9 is provided outside the filter element 6. The exhaust port of the back-blowing air bag 9 is connected to the inside of the filter element 6 through a pipe. Through the back-blowing air bag 9, the powder absorbed in the filter element 6 can be blown out for recycling and reuse. A dust removal hood 7 is provided outside the filter element 6. The dust removal hood 7 is fixed on the manifold 3. The area covered by the dust removal hood 7 is a micro-negative pressure area. An exhaust fan 5 is provided at the top of the manifold 3.

[0015] In use: the exhaust fan 5 draws air from the inside of the dust collector 7 to create a slightly negative pressure environment. The powder around the dust collector 7 flows to the filter element 6 under the negative pressure and is absorbed by the filter element 6 to achieve the purpose of dust removal. This device can be installed in conjunction with the feeding device to greatly reduce the amount of powder thrown out during the feeding process.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
