Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing equipment, in particular to a dust removal device. Background Art

[0002] In the current industrial production process, especially in the field of high-tech, precise control of the quality of each production link has become the key to ensuring the performance of the final product. As an important component of new energy products, each step in the manufacturing process of lithium-ion batteries is directly related to the performance, safety and life of the battery. In the production process of lithium-ion batteries, the cutting of pole pieces is a crucial link. However, during the implementation of pole piece cutting, the problem of pole piece dust generated has always been a difficult problem that needs to be solved in technology research and development and engineering applications.

[0003] The dust generated during the cutting process of lithium-ion battery pole pieces will seriously affect the surface quality of the pole pieces, and thus affect the assembly and final performance of the battery. If these tiny dust particles are not effectively removed, they will form potential short-circuit points inside the battery, posing a threat to the safety and long-term stability of the battery. Therefore, effective treatment and control of dust is the key to improving battery production quality and ensuring battery performance and safety.

[0004] However, the traditional dust treatment process uses a single-chamber and single-layer dust box, which can no longer meet the needs of actual production. In these traditional solutions, although the air intake duct of the dust box is designed to have a wind speed of ≥15m / s, aiming to absorb the generated dust as efficiently as possible, the actual dust collection efficiency is far lower than expected due to the physical distance between the dust collection device and the pole piece surface and the significant drop in wind speed in actual operation. Actual measurements show that the effective wind speed generated at the working position is only 3m / s, that is, the wind speed loss exceeds 80%, which results in a large number of dust particles that cannot be effectively absorbed and still remain in the production environment.

[0005] Therefore, how to increase the flow rate at the air inlet of the dust collection device and improve the adsorption effect has become a technical problem that needs to be solved urgently. Utility Model Content

[0006] The main purpose of the utility model is to provide a dust removal device, aiming to increase the flow rate at the air inlet of the dust suction device and improve the adsorption effect.

[0007] In order to achieve the above object, the utility model provides a dust removal device, comprising:

[0008] The first dust suction pipe has a first air outlet and at least two first air inlets arranged in parallel, and each of the first air inlets is provided with an upper dust suction box for vacuuming the upper surface of the object to be vacuumed; wherein the diameter of each of the first air inlets is smaller than the diameter of the first air outlet.

[0009] Since the diameter of the first air inlet is designed to be smaller than that of the air outlet, it helps to speed up the air flow rate, so that the dust collection efficiency is significantly improved. Each upper dust collection box is easy to disassemble and clean, reducing the maintenance difficulty and cost of the device.

[0010] In one embodiment of the present application, the upper dust box includes:

[0011] an upper cavity cover connected to the first air inlet; and

[0012] The lower cavity cover is connected to the upper cavity cover to form a first return air cavity. A first chamfered right angle is provided on the bottom of the lower cavity cover near the inlet end of the dust to be collected, and a first air inlet hole is provided on the first chamfered right angle.

[0013] The addition of the upper cavity cover, the lower cavity cover and the first chamfered right angle together optimizes the air flow path and increases the contact time between dust and air, thereby improving the dust collection efficiency.

[0014] In one embodiment of the present application, the acute angle formed by the surface where the first chamfered right angle is located and the surface where the bottom of the lower cavity cover is located is 30°.

[0015] During the air flow, the 30° angle helps guide dust particles to smoothly enter the first air inlet. It also helps reduce dust accumulation inside the dust collection system, reduces resistance, and maintains the cleanliness of the dust collection system, extending its service life.

[0016] In one embodiment of the present application, a first O-ring is provided between the lower cavity cover and the upper cavity cover.

[0017] The first O-ring can fill the tiny gap between the upper and lower chamber covers to prevent air leakage, thereby improving the dust collection efficiency and performance of the entire dust collection system. It ensures that during the dust collection process, all air and dust passing through the equipment can flow along the predetermined path, improving the dust removal effect.

[0018] In one embodiment of the present application, it also includes:

[0019] The second dust suction pipe has a second air outlet and at least two second air inlets arranged in parallel, and each of the second air inlets is provided with a lower dust suction box for vacuuming the lower surface of the object to be vacuumed; wherein the diameter of each of the second air inlets is smaller than the diameter of the second air outlet.

[0020] By means of at least two second air inlets arranged in parallel and the corresponding lower dust collection boxes, the system can efficiently vacuum multiple areas at the same time, thereby improving the cleaning efficiency. The second air inlet having a smaller diameter than the second air outlet 31 helps to form an efficient airflow control mechanism inside the dust collection system, thereby improving the dust capture capability and the overall dust collection performance of the system.

[0021] In one embodiment of the present application, the lower dust box includes:

[0022] a lower cavity cover connected to the second air inlet; and

[0023] The upper cavity cover is connected to the lower cavity cover to form a second return air cavity. A second chamfered right angle is provided on the top of the upper cavity cover near the inlet of the dust to be collected, and a plurality of second air inlet holes are provided on the second chamfered right angle.

[0024] The second return air chamber and the second chamfered right angle can effectively control and optimize the air flow direction and velocity during the vacuuming process, improving the vacuuming efficiency. Multiple second air inlet holes help achieve a more uniform suction distribution, increase the dust capture rate, and make the vacuuming process more thorough.

[0025] In one embodiment of the present application, the acute angle formed by the plane where the second chamfered right angle is located and the plane where the top of the upper cavity cover is located is 30°.

[0026] During the air flow, the 30° angle helps guide dust particles to smoothly enter the second air inlet. It also helps reduce dust accumulation inside the dust collection system, reduces resistance, and maintains the cleanliness of the dust collection system, extending its service life.

[0027] In one embodiment of the present application, a second O-ring is provided between the lower cavity cover and the upper cavity cover.

[0028] The first O-ring can fill the tiny gap between the upper cavity cover and the lower cavity cover to prevent air leakage, thereby improving the dust collection efficiency and performance of the entire dust collection system. It ensures that during the dust collection process, all air and dust passing through the equipment can flow along the predetermined path, improving the dust removal effect.

[0029] In one embodiment of the present application, the length direction of the second air inlet hole is perpendicular to the advancing direction of the dust to be vacuumed.

[0030] This helps to create a horizontal airflow during vacuuming, which covers the surface to be cleaned more evenly, thus improving cleaning efficiency. The airflow is perpendicular to the forward direction, which ensures that the suction force is evenly distributed across the entire working width of the vacuum head.

[0031] In one embodiment of the present application, a plurality of blind holes arranged in parallel are provided on the top of the upper cavity cover, and a plurality of through holes connecting the inner and outer spaces of the second return air cavity are provided in each blind hole.

[0032] Through the through holes in the blind hole, air can flow more smoothly in and out of the second return air chamber, which helps to optimize the airflow dynamics of the dust collection system. Good air flow performance can improve dust collection efficiency and reduce power consumption.

[0033] With the above technical solution, since the diameter of the first air inlet is designed to be smaller than the air outlet, it helps to speed up the air flow rate, so that the dust collection efficiency is significantly improved. Each upper dust collection box is easy to disassemble and clean, reducing the maintenance difficulty and cost of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0040] like Figures 1 to 3 As shown, in order to achieve the above purpose, the utility model proposes a dust removal device, comprising:

[0041] The first dust suction pipe has a first air outlet 11 and at least two first air inlets 12 arranged in parallel, and each of the first air inlets 12 is provided with an upper dust suction box for vacuuming the upper surface of the dust object 10; wherein the diameter of each of the first air inlets 12 is smaller than the diameter of the first air outlet 11.

[0042] Specifically, the first dust suction pipe is made of corrosion-resistant metal (such as stainless steel). The first dust suction pipe made of metal material has strong supporting capacity. Of course, according to the design requirements, the first dust suction pipe can also be made of high-strength polymer material. The use of high-strength polymer material can ensure the durability and stability of the first dust suction pipe in long-term use. The first dust suction pipe has a larger first air outlet 11 and at least two first air inlets 12 arranged in parallel, which ensures the flow speed at the first air inlet 12.

[0043] The first air outlet 11 is located at the end of the first dust suction pipe, and its diameter is larger than the first air inlet 12. The first air inlet 12 is arranged at the other end of the first dust suction pipe, and an upper dust suction box is installed on each air inlet. The smaller diameter of the first air inlet 12 helps to increase the speed of the inhaled air, thereby improving the dust suction efficiency.

[0044] The upper dust collecting box is installed on each first air inlet 12, and is used to directly adsorb the surface of the dust object 10. The material of the upper dust collecting box can be made of high-density polyethylene (HDPE) or other chemically resistant materials.

[0045] The first suction pipe is used as a main line, wherein the first air outlet 11 is located at the end of the pipe, and the first air inlet 12 arranged in parallel is arranged at the other end of the first suction pipe. An upper dust box is fixed on each first air inlet 12, so that dust on the upper surface of the object 10 to be suctioned can be directly sucked in.

[0046] With the above technical solution, since the diameter of the first air inlet 12 is designed to be smaller than that of the air outlet, it helps to speed up the air flow rate, so that the dust collection efficiency is significantly improved. Each upper dust collection box is easy to disassemble and clean, which reduces the maintenance difficulty and cost of the device.

[0047] In one embodiment of the present application, the upper dust box includes:

[0048] an upper cavity cover 21 connected to the first air inlet 12; and

[0049] The lower cavity cover 22 is connected to the upper cavity cover 21 to form a first return air cavity. A first chamfered right angle is provided at the bottom of the lower cavity cover 22 near the inlet end of the dust object 10 to be vacuumed. A first air inlet hole 23 is provided at the first chamfered right angle.

[0050] Specifically, the upper cavity cover 21 is directly connected to the first air inlet 12. The upper cavity cover 21 optimizes the air flow path and provides an initial direction and speed for dust absorption. The upper cavity cover 21 can be tightly connected to the first air inlet 12 by a connection mechanism such as screws, buckles or welding to ensure sealing and stability.

[0051] The lower cavity cover 22 is located below the upper cavity cover 21 and is connected thereto to form a first return air cavity. The bottom of the lower cavity cover 22 is designed with a first chamfered right angle on the side close to the inlet end of the dust object 10 to increase the contact area and time between air and dust, thereby improving the dust collection efficiency. The position of the first chamfered right angle optimizes the air inlet angle, making the air flow smoother. At the same time, it avoids scratches between the flat lower cavity cover 22 and the dust object 10 to be vacuumed, thereby improving the safety of the dust object 10 to be vacuumed.

[0052] The first air inlet hole 23 is arranged at the first chamfered right angle, providing a passage for the mixture of dust and air to enter the lower cavity cover 22. By adjusting the size and shape of the first air inlet hole 23, the dust collection performance can be further optimized.

[0053] The upper cavity cover 21 and the lower cavity cover 22 are made of wear-resistant and corrosion-resistant materials, such as ABS plastic, polycarbonate (PC) or light metal (such as aluminum alloy), which not only ensures the firmness of the structure, but also ensures the durability and reliability under long-term use.

[0054] By adopting the above technical solution, the addition of the upper cavity cover 21 and the lower cavity cover 22 and the first chamfered right angle together optimizes the air flow path and increases the contact time between dust and air, thereby improving the dust collection efficiency.

[0055] In one embodiment of the present application, the acute angle formed by the surface where the first chamfered right angle is located and the surface where the bottom of the lower cavity cover 22 is located is 30°.

[0056] With the above technical solution, during the air flow, the 30° angle helps to guide dust particles to smoothly enter the first air inlet 23. It also helps to reduce the accumulation of dust inside the dust collection system, reduce resistance, maintain the cleanliness of the dust collection system, and extend its service life.

[0057] In one embodiment of the present application, a first O-ring 24 is disposed between the lower cavity cover 22 and the upper cavity cover 21 .

[0058] By adopting the above technical solution, the first O-ring 24 can fill the small gap between the upper cavity cover 21 and the lower cavity cover 22 to prevent air leakage, thereby improving the dust collection efficiency and performance of the entire dust collection system. It ensures that during the dust collection process, all air and dust passing through the device can flow along a predetermined path, thereby improving the dust removal effect.

[0059] In one embodiment of the present application, it also includes:

[0060] The second dust suction pipe has a second air outlet 31 and at least two second air inlets 32 arranged in parallel, and each of the second air inlets 32 is provided with a lower dust suction box for vacuuming the lower surface of the object to be vacuumed 10; wherein the diameter of each of the second air inlets 32 is smaller than the diameter of the second air outlet 31.

[0061] Specifically, one end of the second dust suction pipe is provided with a larger second air outlet 31 for discharging the sucked air and dust, and the other side is provided with at least two second air inlets 32 arranged in parallel for sucking dust from different positions.

[0062] Each second air inlet 32 ​​is equipped with a lower dust box, which is specially used to vacuum the lower surface of the object to be vacuumed 10. The lower dust box is fixedly connected to the second air inlet 32 ​​by plugging or screwing, ensuring stability and sealing during vacuuming.

[0063] The diameters of all the second air inlets 32 are smaller than the diameters of the second air outlets 31. This is beneficial for forming effective airflow control and pressure distribution inside the entire system to optimize dust collection efficiency.

[0064] The second suction pipe is made of high-strength, lightweight material, such as ABS plastic or lightweight metal (such as aluminum alloy), to ensure durability without adding extra weight. The lower suction box is made of wear-resistant, impact-resistant material, such as reinforced plastic or flexible rubber, to adapt to different suction surfaces and protect the object to be suctioned 10.

[0065] By adopting the above technical solution, through at least two second air inlets 32 arranged in parallel and the corresponding lower dust collection box, the system can simultaneously efficiently vacuum multiple areas, thereby improving the cleaning efficiency. The second air inlet 32 ​​having a smaller diameter than the second air outlet 31 helps to form an efficient airflow control mechanism inside the dust collection system, thereby improving the dust capture capability and the overall dust collection performance of the system.

[0066] In one embodiment of the present application, the lower dust box includes:

[0067] A lower cavity cover 41 connected to the second air inlet 32; and

[0068] The upper cavity cover 42 is connected to the lower cavity cover 41 to form a second return air cavity. A second chamfered right angle is provided on the top of the upper cavity cover 42 near the inlet of the dust object 10 to be vacuumed, and a plurality of second air inlet holes 44 are provided on the second chamfered right angle.

[0069] Specifically, the lower cavity cover 41 is directly connected to the second air inlet 32. It can be achieved by threaded engagement, snap-fit ​​or other sealing connection methods to ensure good sealing between the two and facilitate disassembly and maintenance.

[0070] The upper cavity cover 42 is fixed on the lower cavity cover 41 to form a closed second return air cavity together with the lower cavity cover 41 .

[0071] A second chamfer is provided at the top of the upper cavity cover 42, near the side of the inlet of the dust object 10 to be collected. This is beneficial to guide the flow direction of air and dust and optimize the airflow dynamics. A plurality of second air inlet holes 44 located on the second chamfer are neatly distributed to guide external air and dust into the lower dust collection box, and then sent into the second air inlet 32 ​​through the lower cavity cover 41.

[0072] By adopting the above technical solution, the second air return cavity and the second chamfered right angle can effectively control and optimize the air flow direction and flow rate during the dust collection process, thereby improving the dust collection efficiency. The multiple second air inlet holes 44 help to achieve a more uniform suction distribution, improve the dust capture rate, and make the dust collection process more thorough.

[0073] In one embodiment of the present application, the acute angle formed by the plane where the second chamfered right angle is located and the plane where the top of the upper cavity cover 42 is located is 30°.

[0074] With the above technical solution, during the air flow, the 30° angle helps to guide dust particles to smoothly enter the second air inlet 44. It also helps to reduce the accumulation of dust inside the dust collection system, reduce resistance, maintain the cleanliness of the dust collection system, and extend its service life.

[0075] In one embodiment of the present application, a second O-ring 43 is disposed between the lower cavity cover 41 and the upper cavity cover 42 .

[0076] By adopting the above technical solution, the first O-ring 43 can fill the small gap between the upper cavity cover 42 and the lower cavity cover 41 to prevent air leakage, thereby improving the dust collection efficiency and performance of the entire dust collection system. It ensures that during the dust collection process, all air and dust passing through the device can flow along a predetermined path, thereby improving the dust removal effect.

[0077] In one embodiment of the present application, the length direction of the second air inlet hole 44 is perpendicular to the moving direction of the dust object 10 .

[0078] The above technical solution is conducive to forming a horizontal airflow during the vacuuming process, which can more evenly cover the surface to be cleaned, thereby improving the cleaning efficiency. The airflow is perpendicular to the forward direction to ensure that the suction force is evenly distributed over the entire working width of the vacuum head.

[0079] In one embodiment of the present application, a plurality of blind holes arranged in parallel are provided on the top of the upper cavity cover 42, and a plurality of through holes 45 connecting the inner and outer spaces of the second return air cavity are provided in each blind hole.

[0080] By adopting the above technical solution, air can flow more smoothly inside and outside the second return air chamber through the through hole 45 in the blind hole, which helps to optimize the airflow dynamics of the dust collection system. Good air flow performance can improve dust collection efficiency and reduce power consumption.

[0081] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
