Description

Technical Field

[0001] The utility model relates to the technical field of battery negative electrode material production, in particular to a material suction vacuum machine for battery negative electrode material production. Background Art

[0002] A vacuum suction machine is a dust-free, closed pipeline conveying equipment that uses vacuum suction to transport granular and powdered materials. It uses the pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, driving the movement of granular or powdered materials, thereby completing the conveying of particles or powders. Since the suction machine uses a closed pipeline for conveying, this conveying method can eliminate dust pollution, improve the working environment, reduce environmental and personnel pollution to materials, and improve cleanliness. In the production process of battery negative electrode materials, a vacuum suction machine is needed.

[0003] At present, vacuum suction machines on the market usually use multiple filter rods to block powder and particles from entering the negative pressure air pump. However, during the long-term suction process, dust and fine particles are easily adhered to the surface of the filter rods, resulting in poor ventilation effect of the filter rods, which reduces the negative pressure in the hopper and causes poor suction effect. This requires opening the sealing cover to clean the filter rods, which takes up production time and affects production efficiency. To this end, we proposed a suction vacuum machine for battery negative electrode material production to solve the above-mentioned problems. Utility Model Content
