Technical Field

[0001] This utility model relates to the field of lithium battery circulating air drying technology, and in particular to a circulating air device for a lithium battery separator drying device. Background Technology

[0002] In the production and processing of lithium batteries, drying is necessary. Drying devices equipped with circulating air systems mainly achieve heating and temperature regulation by circulating hot air. Multiple filter structures (screens) are installed at the air outlet facing the dryer. Over time, the filters accumulate a large amount of dirt, requiring replacement. Traditional circulating air systems can only remove the filters one by one, making it difficult to remove all the filters at once. This causes trouble for users, slows down the filter installation and removal speed, and reduces the filter replacement efficiency.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a circulating air device for a lithium battery separator drying apparatus, which solves the aforementioned problems existing in the prior art.

[0005] The technical solution of this utility model is implemented as follows: A circulating air device for a lithium battery separator drying apparatus includes a housing. Three filters are inserted and installed inside the housing. Fixed blocks are fixedly connected to both ends of one side of each filter. An insertion groove is opened on one side of each fixed block. A sliding hole with equal spacing is opened on one side of the inner cavity of the insertion groove. A locking pin is slidably installed inside the sliding hole. A spring is fixedly connected to one end of the locking pin. The end of the spring away from the locking pin is fixedly connected to the inner wall of the sliding hole. A connecting block is slidably installed inside the insertion groove. A locking groove with equal spacing and adapted to the locking pin is opened on one side of the connecting block.

[0006] The circulating air device for a lithium battery separator drying device described above is further characterized by: a first inclined surface fixedly connected to one side of the connecting block, and a 20-degree inclined surface provided on one side of the first inclined surface.

[0007] The circulating air device for a lithium battery separator drying device described above is further provided with: both ends of one side of the connecting block are provided with inclined surfaces II, and both inclined surfaces II are adapted to the insertion slot.

[0008] The circulating air device for a lithium battery separator drying apparatus as described above further includes: a handle located on the outside of the housing is fixedly connected to one side of the filter screen, and the handle is located at the center of one side of the filter screen.

[0009] The circulating air device for a lithium battery separator drying apparatus as described above further includes: a stepper motor fixedly installed on one side of the housing; the output shaft of the stepper motor passes through the interior of the housing and is fixedly mounted with a rotating shaft; and an impeller is fixedly mounted on the surface of the rotating shaft.

[0010] The circulating air device for a lithium battery separator drying apparatus as described above further includes: an air inlet on one side of the housing, and an end cap that can be detachably installed inside the air inlet.

[0011] The circulating air device for a lithium battery separator drying apparatus as described above further includes: an air outlet channel detachably installed on the top of the housing, and a filter cover detachably installed at one end of the air outlet channel.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a structural design that can connect multiple filter screens together in series. It can disassemble and assemble individual filter screens or connect multiple filter screens together for disassembly and assembly. This can speed up the disassembly and assembly of filter screens, improve the filter screen replacement efficiency of the circulating air device, and provide convenience for the filter screen replacement work of the circulating air device.

[0014] 2. By setting an inclined surface, the top of which is also inclined, the user will feel resistance when sliding the inclined surface, making it easier to push the connecting block into the insertion slot, thus providing convenience for the user's disassembly and assembly work.

[0015] 3. By setting a second inclined surface, the thickness of the connecting block at this end is reduced. When the connecting block is inserted into the insertion slot on the next fixing block, it is less likely to be obstructed and can be inserted smoothly and easily into the corresponding insertion slot to complete the connection of all filter screens, providing convenience for users' disassembly and assembly work.

[0016] 4. This utility model features a handle for users to grip, allowing them to easily remove or insert the filter screen when assembling or disassembling it. The handle is also trapezoidal in shape, making it easier for users to apply force when gripping it, thus providing assistance and convenience for the user's assembly and disassembly work.

[0017] 5. This utility model uses a stepper motor, a rotating shaft, and an impeller. The stepper motor is fixedly mounted on the housing. During operation, the stepper motor drives the rotating shaft to rotate, which in turn drives the impeller to rotate inside the housing. The high-speed rotation of the impeller inside the housing creates negative pressure, which in turn generates suction, ultimately drawing in outside air to complete the wind power delivery, providing convenience for users.

[0018] 6. This utility model features an air inlet and an end cap. The air inlet is the air intake port. When the impeller is driven by the stepper motor, a negative pressure is formed inside the casing, which generates suction to draw in outside air from the air inlet and send it into the drying device. The end cap can play a protective and filtering role, preventing foreign objects from being sucked into the machine during operation, ensuring the normal operation of the circulating air device, and providing convenience for users.

[0019] 7. This utility model, through the setting of an air outlet channel and a filter cover, uses the air outlet channel to change the direction of the air intake, so that the end of the filter cover can be connected to the corresponding equipment (e.g., a drying device). The filter cover is connected between the circulating air device and the drying device. In this way, the air delivered by the circulating air device will be filtered by the filter cover, screening out foreign objects in the air, thereby avoiding damage to the battery separator and preventing foreign objects from sticking to the battery separator, ensuring the quality of battery production, and providing convenience for users' work and use.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] A circulating air device for a lithium battery separator drying apparatus includes a housing 1. Three filters 2 are inserted and installed inside the housing 1. Fixing blocks 3 are fixedly connected to both ends of one side of each filter 2. An insertion groove 4 is provided on one side of the fixing block 3. Sliding holes 5 are evenly distributed on one side of the inner cavity of the insertion groove 4. A locking pin 6 is slidably installed inside the sliding hole 5. A spring 7 is fixedly connected to one end of the locking pin 6. The end of the spring 7 away from the locking pin 6 is fixedly connected to the inner wall of the sliding hole 5. A connecting block 8 is slidably installed inside the insertion groove 4. A locking groove 10 with equal spacing and adapted to the locking pin 6 is provided on one side of the connecting block 8.

[0031] The specific usage process is as follows: First, all the filters 2 are directly inserted into the casing 1. When disassembling, the filters 2 can be pulled out by force. It should be noted that the edge of the filter 2 can be provided with protrusions to ensure that the filter 2 can be firmly stuck in the casing 1, ensuring the stability of the filter 2 after installation and preventing the filter 2 from falling off during machine operation. This is existing technology and will not be explained in detail in this article. Disassembly method one: Since the air is delivered into the dryer from bottom to top, the bottom filter 2 has the most dirt. Therefore, when replacing the filter 2, it should be replaced from bottom to top. This way, the filter with the most dirt can be replaced, and the other cleaner filters 2 can continue to be used, which can reduce the cost of use. When replacing, simply grab the handle 11 on the corresponding position of the filter 2 and pull it outward from the casing 1. This completes the replacement of the filter 2. Similarly, after replacing the new filter 2, grab the handle 11 again, align the filter 2 with the original installation opening on the casing 1, and insert it directly.

[0032] If all the filter screens 2 have accumulated a lot of dirt, they can be disassembled together. During disassembly, first slide the connecting block 8 on the fixing block 3 downwards. The user can press their finger on the inclined surface 9, which is sloped to provide assistance when sliding the connecting block 8, making the sliding easier. As the user slides the connecting block 8, it moves out of the insertion slot 4 on the current fixing block 3 and inserts into the insertion slot 4 on the next adjacent fixing block 3. The locking pin 6 will then hold the connecting block 8 in place within the adjacent fixing block 3. Part of the connecting block 8 will remain within the original fixing block 3, thus securing the two fixing blocks 3 together. The filters are connected in series, and two filters 2 are also connected together. It should be noted that other filters 2 are connected in series with adjacent filters 2 in the same way. Then, by holding any handle 11, the user can remove all filters 2 from the housing 1, thus quickly replacing all filters 2. After replacing with a new filter 2, connect all the new filters 2 together in the same way, and then insert all the filters 2 back into the housing 1. This completes the filter 2 replacement work, improving the efficiency of filter 2 replacement and providing convenience and assistance for users to disassemble and replace filters 2. After all filters 2 are installed, move the connecting block 8 back into the insertion slot 4 on the original fixing block 3. Reset, in which, when the connecting block 8 enters the insertion slot 4 on the next fixing block 3, it first squeezes the locking pin 6 into the sliding hole 5, and then sequentially presses the locking pin 6 on the moving path into the corresponding sliding hole 5. At the same time, the locking pin 6 also engages in the corresponding slot 10 on the connecting block 8, thereby fixing the connecting block 8 onto the fixing block 3, thus firmly connecting the two fixing blocks 3 together, providing convenience for the user's disassembly and assembly. The top of the inclined surface 9 is also inclined, so when the user slides the inclined surface 9, they will feel resistance, making it easier to push the connecting block 8 into the insertion slot 4, providing convenience for the user's disassembly and assembly. An inclined surface 19 is provided at the end of the connecting block 8, so the thickness of this end of the connecting block 8 is reduced. When the connecting block 8 When inserted into the insertion slot 4 on the next fixing block 3, it is not easily obstructed and can be smoothly and easily inserted into the corresponding insertion slot 4, completing the connection of all filter screens 2, providing convenience for users' disassembly and assembly work. The handle 11 is for users to grip, so that users can grasp the handle 11 to take out or insert the filter screen 2 when disassembling and assembling it. Moreover, the handle 11 is designed in a trapezoidal shape, which makes it easy for users to exert force when gripping, providing assistance and convenience for users' disassembly and assembly work. The stepper motor 12 is fixedly mounted on the housing 1. When working, the stepper motor 12 will drive the rotating shaft 13 to rotate, and the rotating shaft 13 will drive the impeller 14 to rotate inside the housing 1. The high-speed rotation of the impeller 14 inside the housing 1 creates negative pressure, thereby generating suction.Finally, outside air is drawn in to complete the airflow transmission, providing convenience for users. The specific principle is existing technology and will not be elaborated upon in this article. Inlet 15 is the air intake. With the stepper motor 12 driving the impeller 14 to rotate, a negative pressure is formed inside the casing 1, generating suction to draw outside air in through inlet 15 and into the drying device. End cap 16 serves a protective and filtering function, preventing foreign objects from being sucked into the machine during operation, ensuring the normal operation of the circulating air device, and providing convenience for users. Exhaust channel 17 is used to change the direction of the incoming air, allowing the end of filter cover 18 to be connected to corresponding equipment, such as the drying device. Filter cover 18 connects the circulating air device and the drying device, so the air transported by the circulating air device is filtered by filter cover 18, screening out foreign objects in the air, thus preventing damage to the battery separator and preventing foreign objects from sticking to the battery separator, ensuring the quality of battery production, and providing convenience for users.

[0033] Therefore, a structural design that allows multiple filters to be connected in series can be adopted. This allows for the disassembly and assembly of individual filters or multiple filters to be connected together for disassembly and assembly. This speeds up the disassembly and assembly of filters, improves the filter replacement efficiency of the circulating air system, and provides convenience for filter replacement work of the circulating air system.

[0034] One side of the connecting block 8 is fixedly connected to an inclined surface 9, and one side of the inclined surface 9 is provided with an inclination of 20 degrees.

[0035] Specifically, the top of the inclined plane 9 is also inclined, so when the user slides the inclined plane 9, they will feel resistance, making it easier to push the connecting block 8 into the insertion slot 4, thus providing convenience for the user's disassembly and assembly work.

[0036] Both ends of one side of the connecting block 8 are provided with inclined surfaces 19, and both inclined surfaces 19 are adapted to the insertion slot 4.

[0037] Specifically, the second inclined surface 19 is set at the end of the connecting block 8, so that the thickness of this end of the connecting block 8 is reduced. When the connecting block 8 is inserted into the insertion slot 4 on the next fixing block 3, it is not easily obstructed and can be inserted into the corresponding insertion slot 4 smoothly and easily, completing the connection of all filter screens 2, and providing convenience for the user's disassembly and assembly work.

[0038] A handle 11 located on the outside of the housing 1 is fixedly connected to one side of the filter screen 2, and the handle 11 is located at the center of one side of the filter screen 2.

[0039] Specifically, the handle 11 is designed for the user to grip, so that the user can grip the handle 11 to take out or insert the filter screen 2 when disassembling or assembling it. Moreover, the handle 11 is designed in a trapezoidal shape, which makes it easier for the user to exert force when gripping it, thus providing assistance and convenience for the user's disassembly and assembly work.

[0040] A stepper motor 12 is fixedly installed on one side of the housing 1. The output shaft of the stepper motor 12 passes through the interior of the housing 1 and is fixedly installed with a rotating shaft 13. An impeller 14 is fixedly installed on the surface of the rotating shaft 13.

[0041] Specifically, the stepper motor 12, the rotating shaft 13, and the impeller 14 are configured such that the stepper motor 12 is fixedly mounted on the housing 1. During operation, the stepper motor 12 drives the rotating shaft 13 to rotate, which in turn drives the impeller 14 to rotate within the housing 1. The high-speed rotation of the impeller 14 within the housing 1 creates negative pressure, thereby generating suction and ultimately drawing in outside air to complete the wind power delivery, providing convenience for the user's work. The specific principle is existing technology and will not be explained in detail in this article.

[0042] An air inlet 15 is provided on one side of the housing 1, and an end cap 16 is detachably installed inside the air inlet 15.

[0043] Specifically, regarding the configuration of the air inlet 15 and the end cover 16, the air inlet 15 is the air intake. When the impeller 14 is rotated by the stepper motor 12, a negative pressure is formed inside the casing 1, which generates suction and draws in outside air from the air inlet 15 and sends it into the drying device. The end cover 16 can play a protective and filtering role, preventing foreign objects from being sucked into the machine during operation, ensuring the normal operation of the circulating air device, and providing convenience for users' work.

[0044] The top of the housing 1 is detachably equipped with an air outlet channel 17, and a filter cover 18 is detachably installed at one end of the air outlet channel 17.

[0045] Specifically, the air outlet channel 17 and the filter cover 18 are designed so that the air outlet channel 17 can change the direction of the air intake, allowing the end of the filter cover 18 to be connected to the corresponding equipment, such as a drying device. The filter cover 18 is connected between the circulating air device and the drying device, so that the air delivered by the circulating air device will be filtered by the filter cover 18, screening out foreign objects in the air, thereby avoiding damage to the battery separator and preventing foreign objects from sticking to the battery separator, ensuring the quality of battery production and providing convenience for users' work.
