Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a battery dust filter cartridge cleaning device. Background Technology
[0002] Lithium-ion batteries are becoming increasingly intertwined with people's lives. In the lithium-ion battery industry, dust and foreign matter are the nemesis of the manufacturing process. Foreign matter between the positive and negative electrodes can cause uneven local electrochemical reactions, or localized leakage current leading to self-discharge. In severe cases, localized thermal failure can even lead to safety accidents involving lithium batteries. Therefore, controlling and cleaning dust has been a key focus for all lithium-ion battery manufacturers from the very beginning.
[0003] In the manufacturing process of lithium batteries, multiple steps require the use of battery dust filters to remove dust and particulate matter generated during production, preventing these particles from entering the production environment and contaminating equipment or affecting the health of operators. Examples include: active materials (such as positive or negative electrode materials) flying up during high-speed stirring in the slurry homogenization process; volatiles from the slurry during coating; positive electrode aluminum shavings and negative electrode copper shavings generated during the winding, laser die-cutting of flexible electrode tabs; and airborne particles in the production environment. These dust particles need to be collected by a dust collection system and filtered through the battery dust filter.
[0004] After prolonged use, battery dust filter cartridges accumulate excessive dust. The dust and particles mainly consist of cleanable solids such as graphite, ternary materials, positive and negative electrode metal fragments, and environmental dust. The battery dust filter cartridge can be reused after cleaning, but during cleaning, the dust and particles tend to spread irregularly in the space, affecting cleaning efficiency and causing secondary pollution to the environment. Utility Model Content
[0005] The purpose of this invention is to provide a battery dust filter cartridge cleaning device to solve the problem of cleaning battery dust.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A battery dust filter cartridge cleaning device includes an air gun, a filter cartridge processing chamber, an exhaust fan, and a dust collection pipe; the filter cartridge processing chamber has a receiving cavity for placing battery dust filter cartridges, the filter cartridge processing chamber has an upper opening and a bottom outlet, the bottom outlet is connected to the dust collection pipe; one end of the dust collection pipe is connected to the bottom outlet of the filter cartridge processing chamber, and the other end is connected to the exhaust fan.
[0008] The edge of the upper opening of the filter cartridge processing chamber has a slot for engaging the upper end of the battery dust filter cartridge with the upper opening of the filter cartridge processing chamber; the upper part of the filter cartridge processing chamber has an anti-backflow cover, the middle of which has an opening that can be connected to the air gun; the anti-backflow cover covers the upper end of the battery dust filter cartridge, and an anti-backflow pad is provided on the inner side of the anti-backflow cover.
[0009] To optimize the above technical solution, the specific measures also include:
[0010] The slot includes an inner ring structure, an outer ring structure, and a groove between them. The inner diameter of the inner ring structure is approximately equal to the outer diameter of the battery dust filter cartridge. The inner diameter of the outer ring structure is larger than the outer diameter of the top ring of the battery dust filter cartridge.
[0011] Furthermore, the inner wall of the outer ring structure of the slot is provided with locking teeth, which are used to fix the top ring of the battery dust filter cartridge.
[0012] As a preferred embodiment, a collar is provided inside the tank.
[0013] Furthermore, the anti-backflow cover covers the slot when installed on the upper part of the filter cartridge processing chamber.
[0014] Furthermore, the upper surface of the anti-backflow cover is provided with several protrusions along the edge, and the upper part of the filter cartridge processing chamber is provided with a flip-up buckle, which can be flipped and fastened to the protrusions.
[0015] Furthermore, the anti-recoil pad includes a spring member and an elastic pad body, wherein the elastic pad body is connected to the inner side of the anti-recoil cover by a plurality of spring members.
[0016] As a preferred embodiment, the surface of the elastic pad facing the battery dust filter cartridge has a corrugated structure.
[0017] Furthermore, the upper part of the filter cartridge treatment chamber is provided with an air gun fixing component on the outer periphery of the anti-backflow cover. The air gun fixing component is used to further clamp the air gun placed at the upper end of the filter cartridge treatment chamber.
[0018] Furthermore, the filter cartridge processing chamber is provided with a closable door on its side.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This invention places the battery dust filter cartridge inside the filter cartridge processing chamber. After turning on the air gun at one end and the induced draft fan at the other end, the dust and particles can be vibrated inside the filter cartridge processing chamber and then discharged and collected from the dust collection pipe.
[0021] This invention addresses the problem of dust diffusion and secondary pollution that easily occurs during the cleaning of battery dust filter cartridges. A slot is provided at the upper opening of the filter cartridge processing chamber. The slot tightly engages the upper end of the battery dust filter cartridge with the upper opening of the filter cartridge processing chamber. An anti-backflow cover is also provided to cover the upper end of the battery dust filter cartridge. The combined use of the slot and the anti-backflow cover can not only fix the battery dust filter cartridge, but also enhance the seal, prevent dust leakage, and reduce dust backflow and overflow.
[0022] Preferably, the inner ring structure of the slot, the outer ring structure of the slot, the groove between the two, and the collar set in the groove can effectively fix and seal the upper outer periphery of the battery dust filter cartridge; the double buffering effect of the spring and elastic pad on the inner side of the anti-backflow cover can achieve a better anti-dust backflow effect.
