Description

Technical Field

[0001] This utility model relates to the technical field of graphite processing equipment, specifically a high-efficiency grinding device for graphite production. Background Technology

[0002] Graphite possesses excellent electrical and thermal conductivity, lubricity, and chemical stability, making it widely used in numerous fields such as electronics, energy, materials science, machinery, and chemicals. For example, it is used as a raw material in the production of refractory materials, electrodes, lubricants, coatings, graphene, and carbon fibers. The demand for graphite powder is large, requiring efficient grinding equipment to meet production needs.

[0003] Chinese patent CN219663877U discloses a grinding device for graphite powder production, including an operating table, a support frame, and a grinding chamber. The support frame is fixedly installed on the operating table, and the grinding chamber is fixedly installed on the support frame. In this invention, by incorporating a fan, a conveying pipe, and a filter cover, the fan blows the graphite powder from the grinding chamber into the conveying pipe, which then transports it to a collection box. Unground graphite particles remain in the grinding chamber for further grinding, improving the grinding effect and saving workers' time. The filter screen in the exhaust pipe prevents graphite powder from spilling during grinding and collection, avoiding waste.

[0004] The aforementioned graphite grinding device cannot control the conveying efficiency of graphite raw materials during use, resulting in a disproportion between grinding efficiency and conveying efficiency. This leads to an accumulation of excessive graphite raw materials in the grinding box, causing blockages.

[0005] Therefore, this utility model provides a high-efficiency grinding device for graphite production to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-efficiency grinding device for graphite production. This solves the problem that the aforementioned grinding devices for graphite production cannot control the conveying efficiency of graphite raw materials during use, resulting in a disproportion between grinding efficiency and conveying efficiency. Consequently, excessive graphite raw materials accumulate in the grinding box, causing blockages.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency grinding device for graphite production, comprising a grinding box, a quantity control component fixed on the top of the grinding box, and a collection component fixed on the side of the grinding box;

[0008] The control component includes a support block, a first motor fixed to the side of the support block, a sector gear fixed to the output end of the first motor, a driven gear meshing with the top of the sector gear, a rotating shaft fixed in the driven gear, a rotating disk fixed to the other end of the rotating shaft, a rotating shaft fixed to the side of the rotating disk, a connecting rod hinged to the rotating shaft, a slider hinged to the other end of the connecting rod, and a control plate fixed to the other end of the slider.

[0009] Preferably, the rotating shaft is rotatably connected directly above the sector gear, and two sets of rotating disks are provided, with a transmission belt sleeved between the two sets of rotating disks.

[0010] Preferably, the grinding box has a feed inlet fixed on the top, an extension block fixed on the side of the feed inlet, a groove in the extension block, a slider slidably connected in the groove, and a measuring plate slidably connected to the side of the feed inlet.

[0011] Preferably, a first grinding bucket is fixed inside the grinding box, and a second grinding bucket is fixed directly below the first grinding bucket. Both the first and second grinding buckets contain a mesh screen.

[0012] Preferably, the collection component includes a suction pipe, a blower is fixed to the top of the suction pipe, a second motor is fixed to the side of the blower, and an impeller is fixed to the output end of the second motor.

[0013] Preferably, the exhaust fan has an air outlet on the side away from the second motor.

[0014] Beneficial effects

[0015] This invention provides a high-efficiency grinding device for graphite production. Compared with the prior art, it has the following advantages:

[0016] (1) A high-efficiency grinding device for graphite production, which uses a flow control device to control the flow of graphite raw materials, thereby preventing excessive graphite raw materials from accumulating in the grinding box and causing blockage. At the same time, by setting up grinding components, graphite powder can be graded and ground, so that when subsequent graphite raw materials are put into the grinding box, the graphite raw materials cannot be mixed with the ground graphite powder. This not only prevents the ground graphite powder from being over-ground, but also prevents graphite powder of different particle sizes from mixing.

[0017] (2) A high-efficiency grinding device for graphite production, which, by setting up a collection component, enables negative pressure suction of the dust generated during the grinding process in the grinding box, thereby preventing excessive dust accumulation inside the grinding box from polluting the external working environment and avoiding dust explosion.

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-3 A high-efficiency grinding device for graphite production includes a grinding box 1, a quantity control component 2 fixed on the top of the grinding box 1, and a collection component 3 fixed on the side of the grinding box 1.

[0026] The control component 2 includes a support block 21, a first motor 22 fixed to the side of the support block 21, a sector gear 23 fixed to the output end of the first motor 22, a driven gear 24 meshing with the top of the sector gear 23, a rotating shaft 25 fixed in the driven gear 24, a rotating disk 26 fixed to the other end of the rotating shaft 25, a rotating shaft 27 fixed to the side of the rotating disk 26, a connecting rod 28 hinged to the rotating shaft 27, a slider 29 hinged to the other end of the connecting rod 28, and a control plate 214 fixed to the other end of the slider 29.

[0027] The rotating shaft 25 is rotatably connected to the top of the sector gear 23. Two sets of rotating disks 26 are provided, and a transmission belt 212 is sleeved between the two sets of rotating disks 26. The transmission belt 212 is used to drive the rotating disk 26 on the side away from the first motor 22 to rotate. The outer side of the rotating disk 26 is provided with a groove so that the transmission belt 212 rotates in the groove, thereby preventing the transmission belt 212 from coming off.

[0028] The top of the grinding box 1 is fixed with a feed inlet 213, and an extension block 210 is fixed on the side of the feed inlet 213. A groove 211 is opened in the extension block 210. A slider 29 is slidably connected in the groove 211. A control plate 214 is slidably connected to the side of the feed inlet 213. The slider 29 can move in the groove 211 by being pushed by the connecting rod 28, thereby driving the control plate 214 to open and close, so that graphite raw materials can be fed intermittently.

[0029] A first grinding hopper 215 is fixed inside the grinding box 1, and a second grinding hopper 216 is fixed directly below the first grinding hopper 215. Both the first grinding hopper 215 and the second grinding hopper 216 are fixed with a mesh 217. The aperture of the mesh 217 in the second grinding hopper 216 is smaller than that in the mesh 217 in the first grinding hopper 215, so that the graphite raw material and the ground graphite powder can be separated, thereby achieving the same size of graphite powder produced.

[0030] In this embodiment, when there is a large amount of graphite material inside the grinding box 1, the first motor 22 can drive the sector gear 23 to mesh with the driven gear 24, thereby causing the rotating disk 26 at the other end of the rotating shaft 25 to rotate. When the rotating disk 26 rotates, the rotating shaft 27 on the side of the rotating disk 26 is hinged to the connecting rod 28 during rotation, which can push the connecting rod 28 to drive the slider 29 to slide in the groove 211 of the extension block 210, thereby allowing the slider 29 to drive the control plate 214 to open and close. When the rotating disk 26 rotates, the transmission belt 212 sleeved on the rotating disk 26 drives the rotating disk 26 on the other side of the feed port 213 to rotate, thereby allowing the control plate 214 to open and close. The graphite raw materials are intermittently fed by opening and closing synchronously. When it is necessary to control the feeding speed of the control plate 214 according to the grinding efficiency inside the first grinding hopper 215, the opening and closing frequency of the control plate 214 can be controlled by controlling the rotation speed of the sector gear 23 driven by the first motor 22. When new graphite raw materials enter the first grinding hopper 215, the first grinding hopper 215 can grind the graphite raw materials and semi-finished graphite powder synchronously. The ground graphite powder falls into the second grinding hopper 216 through the screen 217. The second grinding hopper 216 grinds the graphite powder again, so that the ground graphite powder is discharged through the screen 217.

[0031] Example 2:

[0032] Please see Figure 1-4 Based on Embodiment 1, this embodiment provides a technical solution for a collection component 3, which includes a suction pipe 31, a blower 32 fixed to the top of the suction pipe 31, a second motor 33 fixed to the side of the blower 32, and an impeller 34 fixed to the output end of the second motor 33.

[0033] The blower 32 has an air outlet 35 on the side away from the second motor 33. The air outlet 35 allows the dust in the grinding box 1 to be discharged from the air outlet 35, thereby preventing excessive dust accumulation in the grinding box 1. The air outlet 35 is also equipped with a filter screen to prevent the dust from affecting the external environment.

[0034] In this embodiment, when the graphite raw material is being ground inside the grinding box 1, a large amount of dust is generated inside the grinding box 1. At this time, the impeller 34 is driven to rotate by the second motor 33, which causes the blower 32 to continuously generate negative pressure. The dust inside the grinding box 1 flows into the blower 32 through the suction pipe 31 through the negative pressure, and is then filtered out of the air outlet 35 and discharged to the outside of the grinding box 1 by the rotation of the impeller 34.
