Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a pneumatic cleaning device. Background Technology

[0002] In the production process of power batteries in the lithium battery industry, when the coated electrode sheet experiences a break in the tape or other sudden tape movement inside the oven, the electrode slurry on it is prone to splashing and adhering to the inner wall, air duct, and heating element of the oven after drying. This results in low heat transfer efficiency, increased energy consumption, and corrosion of the oven. For example, the NMP (N-methylpyrrolidone) solvent in the electrode slurry can corrode the inner wall of the oven, and the dried electrode slurry (such as NMP solvent residue, PVDF (polyvinylidene fluoride) binder, conductive agent, etc.) is easy to fall off and mix into the electrode slurry on the surface of the electrode sheet. This leads to uneven coating on the electrode sheet surface, affecting the consistency of the battery and reducing the quality of the electrode sheet, thereby reducing the performance of the battery (such as increased internal resistance and shortened cycle life). Therefore, cleaning the inner wall, air duct, and heating element of the oven is necessary.

[0003] Currently, cleaning the inner walls, air ducts, and heating elements of the drying oven is mainly done manually or with electric vacuum cleaners. Manual cleaning requires operators to use scraping tools to physically remove the adhered, dried electrode slurry. While this achieves a cleaning effect, it is time-consuming, labor-intensive, and inefficient. In contrast, electric vacuum cleaners significantly save manpower and improve efficiency, but their motors are prone to generating electrical sparks during operation. If these sparks come into contact with the electrode slurry particles accumulated inside the vacuum cleaner, they can easily cause an explosion, making it difficult to ensure operational safety.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0035] First Embodiment

[0036] Please refer to Figures 1 to 8 An embodiment of this utility model provides a pneumatic cleaning device, including a body 10, a pneumatic motor 20, an air inlet pipe (not shown in the figure), an air outlet pipe (not shown in the figure), a fan blade 30, a rotating cleaning component, and a dust collection box 50.

[0037] The body 10 is equipped with a filter screen 11, which divides the interior of the body 10 into a first air chamber 12 and a second air chamber 13. An exhaust port 14 communicating with the first air chamber 12 is provided on the outer wall of one end of the body 10, and a dust suction port 15 communicating with the second air chamber 13 is provided on the outer wall of the other end of the body 10.

[0038] A pneumatic motor 20 is housed within the first air chamber 12. The pneumatic motor 20 is a conventional vane-type pneumatic motor, and its structure will not be described in detail here. One end of the intake pipe extends into the first air chamber 12 and connects to the air inlet 21 of the pneumatic motor 20; the other end of the intake pipe connects to the outlet of the extraction device. One end of the outlet pipe extends into the first air chamber 12 and connects to the air outlet 22 of the pneumatic motor 20; the other end of the outlet pipe connects to the air inlet of the extraction device. The extraction device is located within the workshop and is either an air compressor or an air pump. A fan blade 30 is located within the first air chamber 12 and between the pneumatic motor 20 and the filter screen 11. The fan blade 30 is connected to the end of the output shaft 20a of the pneumatic motor 20. A rotating cleaning component is located within the second air chamber 13, and part of the rotating cleaning component passes through the suction port 15 and is located outside the body 10. The rotating cleaning component is connected to the fan blade 30. The rotating cleaning component is used to brush off the dried electrode paste from the inner wall of the oven, the air duct, and the heating element. The dust collection box 50 is located on one side of the outer wall of the body 10, and the interior of the dust collection box 50 is connected to the second air chamber 13.

[0039] In this embodiment, the rotating cleaning component is a rotating brush 40.

[0040] With the above structure, during operation, the air extraction device is activated, and compressed air is input into the pneumatic motor 20 through the air inlet pipe and the air inlet 21 of the pneumatic motor 20. The compressed air inside the pneumatic motor 20 drives the motor blades to rotate, thereby rotating the output shaft 20a of the pneumatic motor 20. The compressed air, after performing work, returns to the air extraction device through the air outlet 22 and the air outlet pipe of the pneumatic motor 20. The rotation of the output shaft 20a of the pneumatic motor 20 drives the fan blades 30 to rotate, which in turn drives the rotating brush 40 to rotate. The rotation of the rotating brush 40 cleans the inner wall of the oven and the air ducts. The rotating brush 40 brushes up the dried electrode paste on the heating element, forming electrode paste particles. Simultaneously, the rotation of the fan blades 30 quickly removes air from the second air chamber 13, creating a negative pressure. This negative pressure generates strong suction, drawing the electrode paste particles from the suction port 15 into the second air chamber 13. The particles are then filtered out by the filter screen 11 and enter the dust collection box 50. The air carried away by the fan blades 30 is discharged from the exhaust port 14. This process cleans the inner walls of the oven, the air ducts, and the heating element. Filtering out the electrode paste particles through the filter screen 11 prevents the air discharged from the exhaust port 14 from polluting the workshop environment and the electrode sheets.

[0041] Furthermore, a dustproof net 16 is provided on the outer wall of one end of the body 10, and the dustproof net 16 corresponds to the exhaust port 14. The dustproof net 16 can exhaust gas and prevent external dust and other objects from entering the first air chamber 12, thereby protecting the pneumatic motor 20 and the fan blades 30.

[0042] In this embodiment, a first body through hole 17 communicating with the first air chamber 12 is provided on one outer wall of the body 10. A connecting plate 23 is provided on one inner wall of the body 10 at a position corresponding to the first body through hole 17. A mounting plate 24 is provided on the side of the connecting plate 23 near the pneumatic motor 20. The connecting plate 23 and the mounting plate 24 form an L-shaped structure. The pneumatic motor 20 is disposed on the side of the mounting plate 24 near the exhaust port 14. The output shaft 20a of the pneumatic motor 20 passes through the mounting plate through hole of the mounting plate 24. The connecting plate 23 and the mounting plate 24 provide mounting support for the pneumatic motor 20.

[0043] Furthermore, a hollow, slender handle 18 is provided on one outer wall of the body 10 at a position corresponding to the first body through hole 17, and the interior of the slender handle 18 communicates with the first body through hole 17. Both the inlet and outlet pipes are housed within the slender handle 18. One end of the inlet pipe passes through the first body through hole 17 and the first connecting plate through hole 231 of the connecting plate 23, and connects to the air inlet 21 of the pneumatic motor 20. The other end of the inlet pipe extends from the end of the slender handle 18 and is used to connect to the outlet end of the suction device. One end of the outlet pipe passes through the first body through hole 17 and the second connecting plate through hole 232 of the connecting plate 23, and connects to the air outlet 22 of the pneumatic motor 20. The other end of the outlet pipe extends from the end of the slender handle 18 and is used to connect to the air inlet end of the suction device. The slender handle 18 is suitable for the narrow space inside the oven, making it easy for manual operation from outside the oven. This improves the safety and convenience of oven cleaning operations, while also protecting the air inlet and outlet pipes from burns and tangling, resulting in an aesthetically pleasing appearance.

[0044] In this embodiment, the rotating cleaning component is provided with a connecting shaft 41. The end of the connecting shaft 41 passes through the filter screen hole of the filter screen 11 and is connected to the fan blade 30. The rotation of the fan blade 30 can drive the connecting shaft 41 to rotate, thereby driving the rotating cleaning component to rotate.

[0045] The end of the connecting shaft 41 is detachably connected to the fan blade 30. This structure facilitates the replacement of the rotating cleaning component and the replacement of rotating cleaning components of different shapes to adapt to different electrode slurries, making it widely applicable.

[0046] The fan blade 30 includes a hub 31 and multiple blades 32, such as Figure 6As shown, multiple blades 32 are evenly distributed on the outer wall of the hub 31, and the number of blades 32 can be set according to actual conditions. One end of the hub 31 is fixedly sleeved on the outer periphery of the end of the output shaft 20a of the pneumatic motor 20, and the end of the connecting shaft 41 is inserted into the other end of the hub 31. When actually replacing the rotating cleaning component, first pull the rotating cleaning component and the connecting shaft 41 out of the suction port 15 as a whole, and then pass the end of the connecting shaft 41 of the new rotating cleaning component through the filter screen hole of the filter screen 11 and insert it into the other end of the hub 31.

[0047] In this embodiment, the dust collection box 50 is detachably mounted on one side of the outer wall of the machine body 10. After the dust collection box 50 is filled with electrode slurry particles, it is easy to remove the dust collection box 50 from the machine body 10 and pour out the electrode slurry particles inside the dust collection box 50.

[0048] Specifically, the outer wall of one side of the body 10 is provided with a second body through hole 19 communicating with the second air chamber 13. The outer wall of one end of the dust collection box 50 is provided with a dust collection box opening 51 communicating with the interior of the dust collection box 50 and an annular insertion part 52. The insertion part 52 is arranged around the dust collection box opening 51, and the interior of the insertion part 52 communicates with the dust collection box opening 51. The insertion part 52 is inserted into the second body through hole 19. The interior of the dust collection box 50 communicates with the second air chamber 13 through the dust collection box opening 51 and the interior of the insertion part 52. After the dust collection box 50 is filled with electrode slurry particles, first pull the insertion part 52 of the dust collection box 50 out of the second body through hole 19, then pour out the electrode slurry particles from the dust collection box 50, and then re-insert the insertion part 52 of the dust collection box 50 into the second body through hole 19.

[0049] In this embodiment, as Figures 2 to 5 As shown, the body 10 includes a first part 10a, a second part 10b, and a third part 10c connected in sequence. The first part 10a is rectangular, the second part 10b is an inverted truncated pyramid, and the third part 10c is cylindrical. The interiors of the first part 10a, the second part 10b, and the third part 10c are sequentially connected to form the interior of the body 10. The exhaust port 14 is located at the end of the first part 10a away from the second part 10b, and the suction port 15 is located at the end of the third part 10c away from the second part 10b. A filter screen 11 is disposed inside the first part 10a. A first body through-hole 17 and a second body through-hole 19 are respectively disposed on one side of the outer wall of the first part 10a. A connecting plate 23 is disposed on one side of the inner wall of the first part 10a. The design of the second part 10b as an inverted truncated pyramid and the third part 10c as a cylinder increases the speed at which the fan blades 30 carry away the air in the second air chamber 13.

[0050] The first part 10a, the second part 10b, and the third part 10c are preferably integrally formed for ease of manufacturing.

[0051] In this embodiment, the rotating brush 40 is made of high-temperature resistant and wear-resistant material with a long service life. Examples of such high-temperature resistant and wear-resistant materials include PA66 (Nylon 66). The body 10, the slender handle 18, and the dust collection box 50 are all made of high-temperature resistant material.

[0052] In this embodiment, as Figure 7 As shown, the rotating brush 40 includes a brush holder 42 and a mounting member 43. The mounting member 43 is located at one end of the brush holder 42 near the first air cavity 12. The connecting shaft 41 is provided at the end of the mounting member 43 near the first air cavity 12. Multiple extensions 431 are formed circumferentially on the outer wall of the mounting member 43. The number of extensions 431 can be set according to actual conditions. The extensions 431 protrude from the outer wall of the brush holder 42. A brush body 44 is provided at the end of the extension 431 away from the first air cavity 12. The brush bodies 44 of the multiple extensions 431 are arranged in a ring around the brush holder 42 at intervals. The brush holder 42 and the brush bodies 44 partially pass through the dust suction port 15 and are located outside the body 10. The rotation of the connecting shaft 41 can drive the mounting member 43, the brush holder 42 and the multiple extensions 431 to rotate, thereby driving the brush body 44 to rotate. The rotation of the brush body 44 can brush up the dried electrode paste on the inner wall of the oven, the air duct and the heating element.

[0053] Second Embodiment

[0054] Please refer to Figure 9 The difference between this embodiment and the first embodiment is that the rotating cleaning component is a rotating scraper 60, which is used to scrape off the dried electrode paste on the inner wall of the oven, the air duct, and the heating element.

[0055] During operation, the exhaust device is activated, and compressed air is input into the pneumatic motor 20 through the exhaust pipe and the air inlet 21 of the pneumatic motor 20. The compressed air inside the pneumatic motor 20 drives the motor blades to rotate, which in turn drives the output shaft 20a of the pneumatic motor 20 to rotate. The compressed air, after performing work, returns to the exhaust device through the air outlet 22 and the exhaust pipe of the pneumatic motor 20. The rotation of the output shaft 20a of the pneumatic motor 20 drives the fan blades 30 to rotate, which in turn drives the rotating scraper 60 to rotate. The rotation of the rotating scraper 60 cleans the inner wall of the oven, the air duct, and the heating element. The dried electrode paste on the component is scraped up, forming electrode paste particles. At the same time, the rotation of the fan blade 30 can quickly remove the air in the second air chamber 13, creating a negative pressure in the second air chamber 13. This negative pressure generates a strong suction force. The electrode paste particles scraped up by the rotating scraper 60 can be sucked into the second air chamber 13 from the dust inlet 15 under the action of this suction force. The electrode paste particles can be filtered out by the filter screen 11 and then enter the dust collection box 50. The air carried away by the fan blade 30 is discharged from the exhaust port 14. In this way, the inner wall of the oven, the air duct and the heating element are cleaned.

[0056] In this embodiment, the rotating scraper 60 is made of metal, such as stainless steel, or of high-temperature resistant and wear-resistant materials, such as ceramic materials.

[0057] In this embodiment, the rotating scraper 60 includes a scraper seat 61 and multiple blades 62. The outer wall of the scraper seat 61 near the first air chamber 12 has a first scraper seat opening 611 communicating with the interior of the scraper seat 61. The scraper seat 61 partially passes through the suction port 15 and is located outside the body 10. The outer wall of the scraper seat 61 away from the first air chamber 12 has a second scraper seat opening 612 communicating with the interior of the scraper seat 61. Multiple blades 62 are located within the second scraper seat opening 612 and are arranged in a ring around the center of the second scraper seat opening 612. One end of each blade 62 is connected to the inner wall of the second scraper seat opening 612, and the other end of each blade 62 is connected to the connecting shaft 41. The end of the connecting shaft 41 extends out from the first scraper seat opening 611. The number of blades 62 can be set according to actual conditions. The rotation of the connecting shaft 41 can drive the scraper seat 61 and multiple blades 62 to rotate. The rotation of the blades 62 can scrape off the dried electrode paste on the inner wall of the oven, the air duct, and the heating element.

[0058] This invention comprises a body 10, a pneumatic motor 20, an air inlet pipe, an air outlet pipe, fan blades 30, a rotating cleaning component, and a dust collection box 50. The pneumatic motor 20 drives the rotating cleaning component and fan blades 30 to rotate synchronously. The rotation of the rotating cleaning component brushes or scrapes away the dried electrode slurry on the inner wall of the oven, the air duct, and the heating element, causing the dried electrode slurry to form electrode slurry particles. Simultaneously, the rotation of the fan blades 30 creates a negative pressure within the second air chamber 13 of the body 10, generating a strong negative pressure suction. This negative pressure suction achieves... The electrode slurry particles brushed or scraped up by the rotating cleaning component are sucked away, thus cleaning the inner wall, air duct, and heating element of the oven. Compared with the existing manual cleaning method, this utility model can automatically clean the inner wall, air duct, and heating element of the oven, saving time and effort and improving work efficiency. In addition, this utility model uses a pneumatic motor 20 to drive the rotating cleaning component to rotate. Compared with the existing method of using an electric vacuum cleaner, the pneumatic motor 20 will not generate electric sparks when it is running, thereby avoiding the risk of explosion and ensuring the safety of use.
