Description

Technical Field

[0001] This utility model relates to the field of battery material technology, and in particular to a dust-proof vacuum ball mill for battery materials. Background Technology

[0002] The dust-proof vacuum ball mill for battery materials is a high-efficiency grinding equipment specifically designed for battery materials. Its core feature is that it replaces the traditional open or semi-open grinding chamber with a "vacuum environment", which solves the problem of dust emission from battery materials during the grinding process from the source. At the same time, it takes into account the grinding fineness, material purity and production safety, making it one of the key pieces of equipment in the preparation of new energy battery materials.

[0003] In existing technology, during the switching process of gate valves in traditional equipment, the pressure difference between the vacuum environment and the atmosphere can cause instantaneous airflow, resulting in the overflow of hydrogen storage alloys and lightweight powder materials. The amount of dust emitted in a single operation is relatively large. Existing technology introduces a patented dust cover technology, which forms a closed space by abutting against the sealing strip of the roller mounting ring. With the timing control of the upper and lower gates, dust is prevented from leaking out during the discharge stage. However, in order to maintain the effectiveness of the sealing system, an additional nitrogen purging device and an automatic sealing strip lubrication system are required, which increases the annual operating cost of a single unit. Moreover, the replacement cycle of sealing components is shortened, and the production capacity is reduced. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a butterfly valve and a shut-off valve, consisting of a handle and a rotating rod, are connected sequentially on the feed pipeline. Turning the handle opens the butterfly valve, which is then in a vertical position. The material accumulates on the shut-off valve after passing through the butterfly valve. Opening the shut-off valve prevents dust or leakage during non-vacuum feeding. Starting the motor drives the turntable to rotate, which in turn drives the drive shaft to rotate. The drive shaft rotates relative to the tank body, which can scrape off the nickel hydroxide or hydrogen storage alloy slurry adhering to the inner wall, preventing these slurries from producing dust and falling off after drying. This design can reduce operating costs and increase equipment capacity.

[0022] 2. In this utility model, by gripping the handle and pulling forward forcefully, the baffle is extended, allowing the material to enter the outer casing. The material first passes through filter plate one, then through its pores to filter plate two. The upper layer intercepts large particles of impurities, while the lower layer breaks up material clumps. This double filtration effectively improves the material quality. After the material fills the discharge pipe, the sealing cap is unscrewed to allow it to flow out, preventing air from entering in a non-vacuum state. For subsequent cleaning, filter plate one is removed via the sliding rod, the pores are cleaned to prevent accumulation from affecting the filtration effect, and then its slot is aligned with the sliding rod and lowered to complete the installation. Filter plate two is operated in the same way. The fixing block prevents the filter plate from falling off. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a dust-proof vacuum ball mill for battery materials, comprising a support 1, with support frames 7 fixedly connected to the top left and right sides of the support 1, and a tank 5 rotatably connected to the top left and right sides of the support frames 7. A dustproof mechanism 2 is installed on the top outer side of the support 1 to enhance sealing. A filter mechanism 3 is installed in the middle of the lower side of the support 1 to filter the material. The dustproof mechanism 2 includes a shut-off valve 201, which is connected to the middle of the top of the tank 5. A long pipe 202 is connected to the top of the shut-off valve 201. A rotating rod 204 is rotatably connected to the middle right side of the long pipe 202. A handle 203 is fixedly connected to the right end of the rotating rod 204. A cover 205 is installed on the top of the long pipe 202. Support rods 206 are rotatably connected to the left and right sides of the inside of the tank body 5. Scrapers 207 are fixedly connected to the outer sides of the support rods 206. A drive assembly 208 is installed on the top right side of the bracket 1. The drive assembly 208 includes a motor 2081, which is fixedly connected to the top right side of the bracket 1. A turntable 2082 is fixedly connected to the output end of the motor 2081. A belt 2083 is driven to the bottom outer side of the turntable 2082. A turntable 2084 is driven to the inner top wall of the belt 2083. A drive shaft 2085 is fixedly connected to the middle left side of the turntable 2084. The scrapers 207 are slidably connected to the tank body 5. The drive shaft 2085 is fixedly connected to the support rods 206 and rotatably connected to the tank body 5.

[0033] Specifically, on the feed pipeline, a butterfly valve consisting of a handle 203 and a rotating rod 204, and a shut-off valve 201 are connected in sequence. During operation, the handle 203 is rotated to open the butterfly valve. When the butterfly valve is opened to the vertical position, the material will be conveyed through the butterfly valve and accumulated on the shut-off valve 201. Only at this time is the shut-off valve 201 allowed to be opened. This operation process can effectively avoid dust or material leakage when feeding in a non-vacuum state, ensuring the cleanliness and airtightness of the feeding process. On the inner wall of the tank 5, support rods 206 and scrapers 207 are evenly arranged along the axial direction of the drive shaft 2085. 206 can enhance the stability of the inner wall structure, while scraper 207 undertakes the function of cleaning the inner wall. After starting motor 2081, motor 2081 drives turntable 2082 to rotate. The rotational power of turntable 2082 is transmitted to turntable 2084 through belt 2083, which in turn drives the drive shaft 2085 to rotate. Since the drive shaft 2085 and the tank 5 form a relative rotational motion, scraper 207 can scrape off the nickel hydroxide or hydrogen storage alloy slurry attached to the inner wall of the tank 5 during the rotation process, preventing these slurries from drying and forming dust and falling off, thus ensuring the cleanliness of the inside of the tank 5 and the quality of subsequent processing.

[0034] Reference Figure 1 , Figure 3 and Figure 6 The filter mechanism 3 includes a housing 301, which is fixedly connected to the bottom of the outer wall of the tank 5. Slide rods 308 are fixedly connected to the front and rear ends of both sides of the inner wall of the housing 301. Filter plate 307 is slidably connected to the lower middle part of the inner side of the housing 301. Fixing block 309 is fixedly connected to the bottom of slide rod 308 and is fixedly connected to housing 301. Filter plate 306 is slidably connected to the upper middle part of the inner side of the housing 301. Discharge pipe 302 is connected to the middle of the lower side of the housing 301. A sealing cover 303 is threadedly connected to the rear end of the lower side of the discharge pipe 302. Baffle 305 is slidably connected to the top of the housing 301. Handle 304 is fixedly connected to the front end of baffle 305. Baffle 305 is slidably connected to tank 5. Slide rod 308 is slidably connected to filter plate 306 and filter plate 307.

[0035] Specifically, by grasping handle 304 and applying forward force, baffle 305 is pulled out from housing 301, allowing the material to be processed to smoothly enter the interior of housing 301. After entering, the material first flows through filter plate 306, and then falls through the pores on filter plate 306 onto filter plate 307. The upper filter plate 306 intercepts large particles of impurities in the material, while the lower filter plate 307 breaks up material clumps. Through two progressive filtration processes, the purity and uniformity of the material are effectively improved, ensuring material quality. The filtered material gradually fills discharge pipe 302. At this point, the sealing cap 303 at the end of discharge pipe 302 is unscrewed, allowing the material to flow out smoothly. This design also prevents air from entering in non-vacuum conditions. Inside the housing 301, to ensure the stability of the material processing environment, the filter plate 306 is removed from the housing 301 using the sliding rod 308. Then, the accumulated impurities in the pores of the filter plate 306 are cleaned to prevent excessive clogging and affecting the subsequent filtration effect. After cleaning, the groove on the filter plate 306 is aligned with the sliding rod 308, and then the filter plate 306 is moved downwards along the sliding rod 308 to complete the installation of the filter plate 306. The filter plate 307 is installed in the same manner. The fixing block 309 inside the housing 301 provides support and limits for the installed filter plate, preventing it from falling off during operation.

[0036] Reference Figure 1 , Figure 2 and Figure 3 Rotating shafts 4 are fixedly connected to the left and right sides of the outer side of the tank body 5. The rotating shafts 4 are rotatably connected to the support frame 7. The support frame 8 is fixedly connected to the top rear side of the support frame 1. The motor 9 is fixedly connected to the top right side of the support frame 8. The output end of the motor 9 is fixedly connected to the transmission wheel 10. The outer side of the transmission wheel 10 is connected to the belt 6. The belt 6 is connected to the tank body 5.

[0037] Specifically, the tank body 5 is equipped with a rotating shaft 4, which rotates in conjunction with the support frame 7. The support frame 7 can support the tank body 5 to run stably on the bracket 1. The support frame 8 can stably support the motor 9. When the motor 9 is started, it drives the transmission wheel 10 to rotate, and the transmission wheel 10 drives the belt 6 to rotate, which in turn drives the tank body 5 to run.

[0038] Working principle: A butterfly valve and a shut-off valve 201, consisting of a handle 203 and a rotating rod 204, are connected sequentially on the feed pipe. Rotating the handle 203 opens the butterfly valve. When it is opened to the vertical position, the material accumulates on the shut-off valve 201 through the butterfly valve, allowing the shut-off valve 201 to open. This can prevent dust or leakage during feeding in a non-vacuum state. Support rods 206 and scrapers 207 are evenly distributed along the axial direction of the drive shaft 2085 on the inner wall of the tank 5. The motor 2081 is started to drive the turntable 2082 to rotate. Its rotation is transmitted to the belt 2083, and then to the turntable 2084. Finally, the drive shaft 2085 rotates. The drive shaft 2085 rotates relative to the tank 5, which can scrape off the attached nickel hydroxide or hydrogen storage alloy slurry and prevent dust from falling off after drying.

[0039] Hold handle 304 and pull baffle 305 forward. The material will enter the housing 301. The material will first pass through filter plate 306, and then through the pores on filter plate 306 into filter plate 307. The upper layer can prevent large particles, and the lower layer can prevent material agglomeration. After two filtrations, the quality of the material is higher. The material fills the discharge pipe 302. Unscrew the sealing cover 303 to let it flow out. This also prevents non-vacuum from entering. In the subsequent cleaning work, use slide rod 308 to remove filter plate 306 from the housing 301, clean the pores to prevent excessive accumulation from affecting the filtration effect, then align the groove on filter plate 306 with slide rod 308, and then move it downward to complete the installation. Filter plate 307 is operated in the same way. Fixing block 309 can prevent the filter plate from falling off.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
