A dust-proof grinding device for zinc powder processing

Abstract

This utility model discloses a dust-proof grinding device for zinc powder processing, including a first grinding box, a second grinding box distributed above the first grinding box, and a cover provided at the top of the second grinding box. An inlet is opened on one side of the top of the cover, and a first motor is fixedly installed at the center of the top of the cover. The combination of the first motor, grinding roller, and arc-shaped protrusions effectively achieves thorough grinding of the zinc powder, thereby improving the grinding efficiency. When the first motor operates, it causes the grinding roller connected to its output end to rotate. Since multiple arc-shaped protrusions are evenly distributed on the outer surface of the grinding roller, and these protrusions are all in contact with the inner wall of the second grinding box, the rotation of the grinding roller effectively achieves thorough grinding of the zinc powder, making it finer and improving grinding efficiency.

Description

Technical Field

[0001] This utility model relates to the field of dust-proof grinding devices for zinc powder processing, and in particular to a dust-proof grinding device for zinc powder processing. Background Technology

[0002] Zinc powder has good rust-preventive properties and is one of the main raw materials used to make rust-preventive paint. In the zinc powder production process, a grinding device is needed to grind the zinc raw material, thereby realizing the production of zinc powder.

[0003] For example, the utility model disclosed in CN219402317U discloses a dust-proof grinding device for zinc powder processing. It automatically completes sieving by means of the sieve holes inside the first sieve, so that the zinc powder with a larger particle size can stay in the inner cavity of the second bottom frame, while the zinc powder with a smaller particle size automatically enters the inner cavity of the first bottom frame. This can complete the sieving of the zinc powder after grinding. However, most current dust-proof grinding devices for zinc powder processing are difficult to effectively grind the material to a suitable size when grinding the material, which affects the subsequent utilization of the material. As a result, the material needs to be ground multiple times, which is not only time-consuming and labor-intensive, but also inefficient. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a dust-proof grinding device for zinc powder processing. This device solves the problem that existing dust-proof grinding devices for zinc powder processing rely on the sieve holes inside a first screen to automatically complete sieving, allowing larger zinc powder particles to remain in the inner cavity of the second bottom frame, while smaller zinc powder particles automatically enter the inner cavity of the first bottom frame. This allows for the sieving of the ground zinc powder. However, most current dust-proof grinding devices for zinc powder processing struggle to effectively grind materials to a suitable size, affecting subsequent material utilization and necessitating multiple grinding processes, which is time-consuming, labor-intensive, and inefficient.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust-proof grinding device for zinc powder processing, comprising a first grinding box, a second grinding box distributed above the first grinding box, and a cover provided at the top of the second grinding box. A feed inlet is provided on one side of the top of the cover. A first motor is fixedly installed at the center of the top of the cover, and a grinding roller is connected to the output end of the first motor. An arc-shaped protrusion is provided on the outer surface of the grinding roller, and a through groove is provided on one side of the top of the grinding roller. A feed inlet is provided at the bottom of the second grinding box, and a communicating structure is provided within the inner cavity of the first grinding box. The through structure includes a first grinding chamber, a second grinding chamber, and a discharge port. The first grinding chamber is located inside the top of the first grinding box, and the bottom of the first grinding chamber is connected to the second grinding chamber. The discharge port is located on the bottom side wall of the first grinding box. A second motor is installed on the top side wall of the first grinding box, and the output end of the second motor is connected to a crushing roller. A partition seat is distributed below the crushing roller, and a through hole is opened in the middle section of the partition seat. A third motor is fixedly installed in the middle of the bottom end of the first grinding box, and the output end of the third motor is connected to a cylinder. The other end of the cylinder is fixedly connected to a grinding disc.

[0006] As a preferred embodiment of this utility model, the arc-shaped protrusions are equidistantly distributed along the center point of the grinding roller, and the arc-shaped protrusions and the grinding roller form an integrated structure.

[0007] As a preferred embodiment of this utility model, the discharge ports are equidistantly distributed on the side wall of the first grinding box, and the discharge ports and the first grinding box form an integrated structure.

[0008] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0009] 1. By combining the first motor, grinding roller, and arc-shaped protrusions, the zinc powder can be effectively ground, thereby improving the grinding efficiency. When the first motor is working, the grinding roller connected to its output end will rotate accordingly. Since multiple arc-shaped protrusions are evenly distributed on the outer surface of the grinding roller, and the arc-shaped protrusions are all in contact with the inner sidewall of the second grinding box, the rotation of the grinding roller can effectively grind the zinc powder, making it finer and improving the grinding efficiency.

[0010] 2. By combining the second motor and the crushing roller, the zinc powder can be further ground, ensuring that the zinc powder can be ground to an ideal state. Since there are two crushing rollers and the protrusions on the surfaces of the two grinding rollers mesh with each other, when the two second motors drive the two crushing rollers to rotate in opposite directions, the zinc powder can be fully crushed, improving the fineness of the zinc powder grinding.

An arc-shaped protrusion 7 is provided on the outer surface of the grinding roller 6. A through groove 8 is opened on one side of the top of the grinding roller 6. A feed inlet 9 is opened at the bottom of the second grinding box 2. A communicating structure is opened in the inner cavity of the first grinding box 1.

[0019] In use, the zinc powder to be ground is fed into the inside of the second grinding box 2. After preliminary grinding, the zinc powder is fed into the inside of the first grinding box 1 for further grinding.

[0020] As a further implementation of this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a feed inlet 4 is provided on one side of the top of the cover 3. A first motor 5 is fixedly installed in the middle of the top of the cover 3, and the output end of the first motor 5 is connected to a grinding roller 6. The outer surface of the grinding roller 6 is provided with arc-shaped protrusions 7, which are equidistantly distributed along the center point of the grinding roller 6, and the arc-shaped protrusions 7 and the grinding roller 6 form an integrated structure. A through groove 8 is provided on one side of the top of the grinding roller 6. A feed inlet 9 is provided at the bottom of the second grinding box 2. A first grinding chamber 10 is opened on the inner side of the top of the first grinding box 1, and the bottom of the first grinding chamber 10 is connected to the second grinding chamber 11. A discharge port 12 is provided on the bottom side wall of the first grinding box 1, and the discharge ports 12 are equidistantly distributed. The first grinding chamber 10, the second grinding chamber 11 and the discharge port 12 are distributed on the side wall of the first grinding chamber 1 and form an integrated structure with the first grinding chamber 1. The first grinding chamber 10, the second grinding chamber 11 and the discharge port 12 form a connected structure and the connected structure is set in the inner cavity of the first grinding chamber 1. The top side wall of the first grinding chamber 1 is provided with a second motor 13 and the output end of the second motor 13 is connected to a crushing roller 14. The lower part of the crushing roller 14 is provided with a partition seat 15 and the middle section of the partition seat 15 is provided with a through hole 16.

[0021] In use, firstly, connect the cover 3 to the second grinding box 2 and seal the second grinding box 2. Then, input the zinc powder to be ground into the inner side of the second grinding box 2 through the feed inlet 4. Immediately, the first motor 5 operates, causing the grinding roller 6 connected to its output end to rotate. The rotation of the grinding roller 6 realizes the synchronous movement of the arc-shaped protrusions 7 on its outer surface. In combination with the movement of the arc-shaped protrusions 7, the zinc powder seeping out of the channel 8 is fully ground. After the initial grinding, the zinc powder is input into the inner side of the first grinding box 1 through the feed inlet 9. At the same time, the second motor 13 operates, causing the crushing roller 14 connected to its output end to rotate. The two crushing rollers 14 rotate in opposite directions, and because the protrusions on the surface of the crushing rollers 14 mesh with each other, The zinc powder can be further crushed by the opposing rotating crushing rollers 14. The crushed zinc powder is then fed into the inner side of the second grinding chamber 11 through the through hole 16 in the middle of the partition seat 15. Since the bottom of the partition seat 15 has an inclined surface that matches the inclination of the grinding disc 19, the grinding disc 19 will rotate when the third motor 17 is working. The rotation of the grinding disc 19 will further grind the crushed zinc powder. When the cylinder 18 is working, it will push the grinding disc 19 vertically to adjust its position according to the actual grinding requirements. The finished zinc powder will be discharged through the discharge port 12.
