Description

Technical Field

[0001] This invention belongs to the field of lithium battery technology, and in particular relates to a drying oven for lithium battery production equipment. Background Technology

[0002] Lithium-ion batteries are batteries that contain lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in their electrochemical system. They can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are typically non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

[0003] The raw materials for lithium batteries need to be dried during processing. Drying is usually done using box dryers or drum dryers. However, the drying efficiency is low because the raw materials cannot fully contact and absorb heat.

[0004] This invention designs a rapid dryer that allows the raw materials to fully contact the heat source, thus solving the above problems. Summary of the Invention

A second motor capable of driving the current-dividing shell to rotate is mounted on the base. The outer circumferential surface of the current-dividing shell has multiple through arc-shaped holes evenly distributed around it. A controllable scraper is slidably mounted on each of the arc-shaped holes on the current-dividing shell, and a spring is installed between the controllable scraper and the current-dividing shell.

The output shaft of the second motor is fixedly mounted with a second gear, which meshes with the first gear.

[0012] As a preferred embodiment, the controllable scraper is mounted on two connecting plates on one side inside the diversion shell, and a fixing plate is fixedly mounted on each connecting plate; two telescopic guide rods are installed between each fixing plate and the inner wall of the diversion shell, and two springs are installed between each fixing plate and the inner wall of the diversion shell, with the springs embedded on the outside of the corresponding two guide rods; the springs are compression springs and have preload.

[0016] As a preferred embodiment, a sealing mechanism is installed between the mounting shaft and the flow divider housing.

[0017] As a preferred embodiment, a sealing mechanism is installed between the lower end of the diversion shell and the outer shell.

Detailed Implementation

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following embodiments and drawings are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0033] A lithium battery production equipment oven, such as Figure 1 , 2 As shown in Figure 9, it includes a base 1, a first motor 2, a second motor 3, a housing 4, a controllable scraper 5, a diverter housing 7, a mounting plate 8, a third motor 22, and a trigger slide 25, wherein... Figure 4 As shown, the outer shell 4 is fixedly mounted on the upper side of the base 1 by three circumferentially evenly distributed support arc plates 9, and the upper end of the outer shell 4 has a filling port; as Figure 2As shown, a fixed support 6 is fixedly installed inside the outer casing 4, such as... Figure 2 , 3 As shown, the diverter housing 7 is rotatably installed inside the outer casing 4, with its lower end rotatably installed on the bottom surface of the outer casing 4, and its upper end rotatably installed on the fixed support 6; as Figure 5 As shown, the outer circumferential surface of the diverter shell 7 has multiple arc-shaped holes 10 that are evenly distributed in the inner and outer directions. A first gear 11 is fixedly installed at the lower end of the diverter shell 7, extending through the bottom surface of the outer shell 4. A second motor 3 is fixedly installed on the upper side of the base 1. A second gear 12 is fixedly installed on the output shaft of the second motor 3, and the second gear 12 meshes with the first gear 11. Figure 6 As shown, a controllable scraper 5 is slidably mounted on each of the arc-shaped holes 10 on the diversion shell 7, such as... Figure 7 As shown, the controllable scraper 5 is mounted on one side of the diversion shell 7 with two connecting plates 16 installed vertically. Each connecting plate 16 has a fixed plate 17 fixedly installed on it. Two telescopic guide rods 14 are installed between each fixed plate 17 and the inner wall of the diversion shell 7. Two springs 13 are installed between each fixed plate 17 and the inner wall of the diversion shell 7. The springs 13 are embedded on the outside of the corresponding two guide rods 14. The springs 13 are compression springs with preload. Two limiting plates 15 are installed on both sides of each fixed plate 17 to limit the position of the fixed plate 17. The end of the limiting plate 15 away from the fixed plate 17 is fixedly installed on the inner wall of the diversion shell 7. A transmission plate 18 is fixedly installed on one side of each controllable scraper 5 located inside the diversion shell 7.

[0034] The operation of the second motor 3 will drive the second gear 12 to rotate. The rotation of the second gear 12 will drive the first gear 11 to rotate. The rotation of the first gear 11 will drive the diverter shell 7 to rotate relative to the outer shell 4. The rotation of the diverter shell 7 will drive the controllable scraper 5 installed on it to rotate circumferentially.

[0035] The guide rod 14 guides the corresponding controllable scraper 5, and the limiting plate 15 limits the controllable scraper 5 to ensure that the controllable scraper 5 can be reset under the action of the spring 13.

[0036] like Figure 2 As shown, a mounting shaft 21 is rotatably mounted inside the flow divider housing 7. A fourth gear 20 is fixedly mounted on the lower end of the mounting shaft 21, extending through the lower end face of the flow divider housing 7. Figure 8 As shown, the first motor 2 is fixedly mounted on the upper side of the base 1, and a third gear 19 is fixedly mounted on the output shaft of the first motor 2. The third gear 19 meshes with the fourth gear 20; a fan-shaped mounting plate 8 is fixedly mounted on the upper end of the mounting shaft 21, as shown. Figure 9As shown, three third motors 22 are evenly mounted circumferentially on the mounting plate 8, and a fifth gear 23 is fixedly mounted on the output shaft of the third motor 22; three trigger slide rods 25 are slidably mounted on the upper side of the mounting plate 8 through three sets of guide sleeves 24; the trigger slide rods 25 have teeth, and the three trigger slide rods 25 correspond one-to-one with the three fifth gears 23 and mesh with each other; the trigger slide rods 25 cooperate with the transmission plate 18 mounted on the controllable scraper 5.

[0037] The operation of the first motor 2 drives the third gear 19 to rotate, the rotation of the third gear 19 drives the fourth gear 20 to rotate, the rotation of the fourth gear 20 drives the mounting shaft 21 to rotate, the rotation of the mounting shaft 21 drives the mounting plate 8 to rotate, and the mounting plate 8 drives the third motor 22, the fifth gear 23 and the trigger slide 25 mounted on it to rotate circumferentially.

[0038] The operation of the third motor 22 can drive the fifth gear 23 to rotate. The rotation of the fifth gear 23 causes the corresponding trigger slide 25 to slide relative to the mounting plate 8. The sliding of the trigger slide can push the corresponding transmission plate 18 to slide. The sliding of the transmission plate 18 causes the corresponding controllable scraper 5 to slide.

[0039] In this invention, the outer shell 4 has a heating wire inside and an insulation layer outside.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0041] Implementation method: When using the oven designed according to the present invention, in the initial state, such as Figure 10 As shown in Figure a, each controllable scraper 5 has a gap of thickness d1 between itself and the inner wall of the outer casing 4. During use, the raw material is added from the top of the outer casing 4, and the added material flows into the outer casing 4 along the outer wall of the diversion shell 7. Then, the second motor 3 is controlled to operate, driving the second gear 12 to rotate. The rotation of the second gear 12 drives the first gear 11 to rotate, which in turn drives the diversion shell 7 to rotate relative to the outer casing 4. The rotation of the diversion shell 7 then drives the controllable scraper 5 mounted on it to rotate circumferentially. After several rotations, as... Figure 10As shown in b, the raw material will spread on the inner wall of the outer shell 4 under centrifugal force, and the amount of raw material added will spread on the inner wall of the outer shell 4 to a degree of d2, where d2 is less than or equal to d1. During this process, the first motor 2 will be controlled to work, which will drive the third gear 19 to rotate. The rotation of the third gear 19 will drive the fourth gear 20 to rotate, which will drive the mounting shaft 21 to rotate. The rotation of the mounting shaft 21 will drive the mounting plate 8 to rotate, which will drive the third motor 22, the fifth gear 23 and the trigger slide rod 25 mounted on it to rotate circumferentially, so that the three trigger slide rods 25 are adjacent to one of the controllable scrapers 5. Three controllable scrapers 5 are aligned and rotate at the same speed in the circumferential direction. Three trigger sliders 25 are set in the circumferential rotation direction, namely trigger slider 1 26, trigger slider 27, and trigger slider 3 28 from front to back. The gap between the controllable scraper 5 and the wall of the outer casing 4 can be divided into three states of controllable scraper 5. When the gap between the controllable scraper 5 and the inner wall of the outer casing 4 is d2, the controllable scraper 5 is in state 3; when the gap between the controllable scraper 5 and the inner wall of the outer casing 4 is 0.5d2, the controllable scraper 5 is in state 2; and when the gap between the controllable scraper 5 and the inner wall of the outer casing 4 is 0, the controllable scraper 5 is in state 1. To better understand the workflow of this invention, the number of controllable scrapers 5 installed inside the housing 4 is set to 10, with an included angle of 36 degrees between any two adjacent controllable scrapers 5. Then, the middle third motor 22 of the three third motors 22 is controlled to operate. The operation of the third motor 22 drives the corresponding fifth gear 23 to rotate. The rotation of the fifth gear 23 causes the corresponding trigger slide 25, i.e., trigger slide 27 (number 2), to slide relative to the mounting plate 8. The sliding of trigger slide 27 (number 2) pushes the corresponding transmission plate 18 to slide. The sliding of transmission plate 18 causes the corresponding controllable scraper 5 to slide. In this state, the controllable scraper 5 cooperating with trigger slide 27 (number 2) is in state 2. Figure 10 As shown in c, the controlled scraper 5 is driven to slide along a distance that keeps the gap between it and the inner wall of the outer casing 4 at 0.5d2. In this state, the first motor 2 and the second motor 3 continue to operate, controlling the diversion shell 7 to rotate the controlled scraper 5 one revolution. During this process, the controlled scraper 5 scrapes the material from the inner wall of the outer casing 4 to its front side, removing a thickness of 0.5d2 of material. Figure 10 As shown in d, the thickness of the raw material remaining on the inner wall of the outer shell 4 is 0.5d2; then, the third motor 22 located on the front side is controlled to work, controlling the sliding of the first trigger slide rod 26. The sliding of the first trigger slide rod 26 can push the corresponding transmission plate 18 to slide, and the sliding of the transmission plate 18 drives the corresponding controllable scraper 5 to slide. In this state, the controllable scraper 5 that cooperates with the first trigger slide rod 26 is in state 1, such as Figure 11As shown in e, in state 1, the controlled scraper 5 is driven to slide such a distance that the gap between it and the inner wall of the outer casing 4 is kept at 0. In this state, the first motor 2 and the second motor 3 continue to work, controlling the diversion shell 7 to drive the controlled scraper 5 to rotate 36 degrees. Figure 11 As shown in f, during this process, the controllable scraper 5 in state 1 will scrape the remaining material on the inner wall of the outer shell 4 to its front side, scraping off a material with a thickness of 0.5d2. Simultaneously, the material scraped off by the controllable scraper 5 in state 2 will be centrifugally transferred to the inner wall of the outer shell 4, which has become smooth after being scraped by the controllable scraper 5 in state 1. During this process, the states of the three controllable scrapers 5, which cooperate with the three trigger sliders 25, are state 1, state 2, and state 3 from front to back; as shown in f... Figure 11 As shown in g, the first motor 2 is then controlled to operate. The operation of the first motor 2 drives the third gear 19 to rotate. The rotation of the third gear 19 drives the fourth gear 20 to rotate. The rotation of the fourth gear 20 drives the mounting shaft 21 to rotate. The rotation of the mounting shaft 21 drives the mounting plate 8 to rotate. The mounting plate 8 causes the third motor 22, the fifth gear 23, and the trigger slide rod 25 mounted on it to rotate 36 degrees circumferentially relative to the controllable scraper 5, so that the three trigger slide rods 25 rotate forward 36 degrees relative to all controllable scrapers 5. Figure 11 As shown in i, the first motor 2 is then controlled to operate. The operation of the first motor 2 drives the third gear 19 to rotate. The rotation of the third gear 19 drives the fourth gear 20 to rotate. The rotation of the fourth gear 20 drives the mounting shaft 21 to rotate. The rotation of the mounting shaft 21 drives the mounting plate 8 to rotate. The mounting plate 8 drives the third motor 22, the fifth gear 23, and the trigger slide rod 25 mounted on it to rotate 36 degrees circumferentially relative to the controllable scraper 5, causing the three trigger slide rods 25 to rotate forward by 7 times 36 degrees relative to all controllable scrapers 5. Then, the first motor is controlled to operate, controlling the three trigger slide rods to rotate 36 degrees relative to the controllable scraper, and then the three third motors 22 are controlled to operate, as shown in the figure. Figure 12 As shown in j, the state of the controllable slide, which originally cooperated with the three trigger sliders 25, changed from state 1, state 2, and state 3 from front to back to state 3, state 1, and state 2; then, the first motor 2 and the second motor 3 were controlled to work, as shown in the figure. Figure 12As shown in k, the three trigger scrapers and all controllable scrapers 5 rotate together at the same speed by 36 degrees; controllable scraper 5 in state 1 continues to scrape the material on the inner wall of the outer shell 4, while controllable scraper 5 in state 2 continues to centrifuge the material onto the inner wall of the outer shell 4; then, the first and second motors are controlled to continue working, causing the three trigger scrapers and all controllable scrapers 5 to rotate together at the same speed by 36 degrees; controllable scraper 5 in state 1 continues to scrape the material on the inner wall of the outer shell 4, while controllable scraper 5 in state 2 continues to centrifuge the material onto the inner wall of the outer shell 4; after rotating 36 degrees, the state of the controllable slide plate cooperating with the three trigger slide rods 25 is state 1, state 2, and state 3 from front to back; this state returns to the state shown in the image. Figure 11 The state shown by f in the figure is the initial working state, which is repeated in cycles to dry the raw materials.
