Description

Technical Field

[0001] The utility model relates to the technical field of graphene, in particular to a graphite grinding device. Background Art

[0002] The main component of graphite is carbon. The so-called natural graphite refers to a type of graphite formed under natural conditions. Due to the influence of the natural environment, there is very little pure graphite. It usually needs to be treated and purified before further processing.

[0003] The patent document with publication number "CN219744975U" discloses a spherical graphite grinding device, which is rotated by installing a shaft and a crushing rod. The rotation of the crushing rod can be used to crush large particles of graphite, thereby achieving the effect of grinding large pieces of graphite.

[0004] In the prior art, after graphite is ground, it needs to be filtered through a filter screen, and qualified fine particles are filtered and collected, while larger graphite particles will be left on the filter screen, which will not only affect the filtering effect of the filter screen, but also require staff to manually grind the unfiltered large particles of graphite again, resulting in slower graphite grinding efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the following shortcomings in the prior art: larger graphite particles will be left on the filter screen, which will not only affect the filtering effect of the filter screen, but also require staff to manually grind the unfiltered large graphite particles again, resulting in slower graphite grinding efficiency. A graphite grinding device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A graphite grinding device comprises a box body and a feeding port, wherein a circular cavity is provided at the upper end of the box body, the feeding port is connected to the circular cavity, and one end of the circular cavity is fixedly connected to a door frame;

[0008] A screening component is installed in the box, and the screening component includes a rotating shaft, a scraper, and a filter plate. The rotating shaft is rotatably connected to the door frame, the scraper is L-shaped, one end of the scraper is rotatably connected to the rotating shaft, the filter plate is slidably connected to the box, one end of the rotating shaft is provided with a reciprocating thread pattern, the rotating shaft is threadedly connected to a connecting plate, and the end of the connecting plate away from the rotating shaft is fixedly connected to the filter plate.

[0009] Preferably, the screening component further comprises a roller and a rotating rod, and the two rollers are rotatably connected to the box body via the rotating rod respectively.

[0010] Preferably, fixed blocks are respectively provided at both ends of the rotating roller, and the two fixed blocks are slidably connected between the two rotating rollers, and one of the fixed blocks is rotatably connected to the rotating shaft.

[0011] Preferably, two inclined plates are fixedly connected between the two fixed blocks, the inclined plates are arranged on the upper side of the rotating roller, and the two inclined plates are both arranged in a concave shape.

[0012] Preferably, a first gear is fixedly connected to one of the rotating rods, a second gear is fixedly connected to the rotating shaft, and the first gear is meshingly connected to the second gear.

[0013] Preferably, the scraper is arranged on the upper side of the filter plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The graphite is put in through the feeding port and limited by two inclined plates, and then slides between two rollers. As the rollers rotate, the graphite can be ground. The ground graphite falls onto the filter plate, and the filter plate can screen the ground graphite.

[0016] When the scraper pushes the unfiltered large particles on the filter plate upwards, the graphite will slide down to the inclined plate through the scraper and then slide down between the two rollers for grinding, thereby achieving repeated grinding of graphite with unqualified diameters. At the same time, when the shaft keeps rotating, it can drive the filter plate to move back and forth horizontally through the connecting plate, thereby quickly screening the graphite.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 2 A graphite grinding device comprises a box body 1 and a feed opening 8. A circular cavity is opened at the upper end of the box body 1. The feed opening 8 is connected to the circular cavity. A door frame 11 is fixedly connected to one end of the circular cavity.

[0023] A screening component is installed in the box body 1, and the screening component includes a rotating shaft 5, a scraper 3, and a filter plate 4. The rotating shaft 5 is rotatably connected to the door frame 11, and the scraper 3 is L-shaped. One end of the scraper 3 is rotatably connected to the rotating shaft 5, and the filter plate 4 is slidably connected in the box body 1. One end of the rotating shaft 5 is provided with a reciprocating thread pattern. The rotating shaft 5 is threadedly connected to a connecting plate 10, and the end of the connecting plate 10 away from the rotating shaft 5 is fixedly connected to the filter plate 4. The scraper 3 is arranged on the upper side of the filter plate 4. The screening component also includes a roller 2 and a rotating rod 12. The two rollers 2 are rotatably connected to the box body 1 through the rotating rod 12 respectively. The rotating rod 12 fixedly connected to the first gear 9 rotates counterclockwise, while the other roller 2 rotates clockwise, thereby grinding the graphite.

[0024] Fixed blocks 6 are respectively provided at both ends of the roller 2. The two fixed blocks 6 are slidably connected between the two rollers 2. One of the fixed blocks 6 is rotatably connected to the rotating shaft 5. The fixed block 6 is arranged between the two rollers 2 so that a gap is left between the two rollers 2. Two inclined plates 7 are fixedly connected between the two fixed blocks 6. The inclined plates 7 are arranged on the upper side of the roller 2. The two inclined plates 7 are both arranged in a concave shape. When graphite is poured into the circular cavity through the discharge port 8, the inclined plates 7 can play a blocking role, so that the graphite can slide between the two rollers 2 on the upper surface of the inclined plates 7. A first gear 9 is fixedly connected to one of the rotating rods 12, and a second gear 13 is fixedly connected to the rotating shaft 5. The first gear 9 is meshed with the second gear 13.

[0025] In the utility model, firstly, the rotating rod 12 connected to the first gear 9 is connected to the external servo motor, and the roller 2 is driven to rotate under the drive of the external servo motor, and then the graphite is put in through the discharge port 8 and is limited by the two inclined plates 7, and slides between the two rollers 2. As the rollers 2 rotate, the graphite can be ground, and the ground graphite falls onto the filter plate 4, and the filter plate 4 can screen the ground graphite.

[0026] As the first gear 9 rotates, the second gear 13 can be driven to rotate, and the second gear 13 can drive the rotating shaft 5 to rotate. When the scraper 3 rotates with the rotating shaft 5, the large particles of graphite on the upper side of the filter plate 4 can be pushed and move along the inner wall of the circular cavity. When the scraper 3 pushes the large particles that have not been filtered on the filter plate 4 to the upper side, the graphite will slide onto the inclined plate 7 through the scraper 3 and then slide between the two rollers 2 again for grinding, thereby achieving repeated grinding of graphite with unqualified diameters. At the same time, when the rotating shaft 5 continues to rotate, the filter plate 4 can be driven to move back and forth horizontally through the connecting plate 10, thereby quickly screening the graphite.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
