Description

Technical Field

[0001] This application relates to the field of zircon powder processing technology, and in particular to a zircon powder grinding apparatus. Background Technology

[0002] Zircon powder is a white powdery industrial material made from zircon sand through grinding. It has wide applications in investment casting, ceramics, and refractory materials. In the present technology, the grinding of zircon powder usually adopts a traditional grinding device, which uses two grinding discs to grind the zircon sand. However, the grinding effect of the traditional grinding device is poor, and the ground particles are large, which does not meet the standards for the use of zircon powder, so it needs to be improved. Summary of the Invention

[0003] To improve the grinding effect of zircon powder, this application provides a zircon powder grinding device.

[0004] The zircon powder grinding device provided in this application adopts the following technical solution:

[0005] A zircon powder grinding device includes a grinding cylinder with a grinding chamber inside. A feed pipe is provided on the upper surface of the grinding cylinder and communicates with the grinding chamber. An arc-shaped grinding surface is provided below the grinding chamber. A grinding ball is rotatably connected to the arc-shaped grinding surface. A rotating shaft is provided on the top of the grinding ball. A rotating component is provided on the top wall of the grinding cylinder. The output shaft of the rotating component is inserted into the grinding chamber and connected to the rotating shaft. A powder chamber is also provided inside the grinding cylinder, located below the grinding chamber. A discharge port is provided at the center of the bottom of the arc-shaped grinding surface and communicates with the powder chamber.

[0006] By adopting the above technical solution, the staff adds zircon sand into the grinding chamber through the feed pipe. The zircon sand enters between the arc-shaped grinding surface and the grinding ball. During the rotation of the grinding ball, the zircon sand is continuously ground. Due to the structural characteristics of the arc-shaped grinding surface, the zircon powder will slide towards the bottom of the arc, thereby generating more zircon powder accumulation at the bottom of the arc, achieving uniform grinding of the zircon powder, and improving grinding efficiency and grinding effect.

[0007] Preferably, a grinding block is provided inside the grinding cylinder, the arc-shaped grinding surface is formed on the grinding block, a support plate is provided at the top of the powder chamber, a lifting member is provided on the surface of the support plate, the piston rod of the lifting member is connected to the bottom wall of the grinding block, and the lifting member drives the grinding block to move up and down within the grinding cylinder; a discharge pipe is provided inside the discharge port, the bottom of the discharge pipe is connected to the powder chamber, the top wall of the discharge pipe is arc-shaped, and a discharge groove is formed on the top peripheral wall of the discharge pipe, the discharge groove is connected to the inside of the discharge pipe.

[0008] By adopting the above technical solution, after the zircon sand is ground, the lifting device is activated to lower the grinding block. As a result, the discharge pipe will move relative to the grinding block, and the end of the discharge pipe with the discharge groove will also come above the arc-shaped grinding surface. Due to the structure and shape of the arc-shaped grinding surface, the ground zircon powder will be concentrated at the bottom of the arc. At this time, since the discharge groove is exposed, the zircon powder will enter the discharge groove and enter the powder chamber, thereby realizing the collection and control of zircon powder. This allows the grinding balls to grind the zircon sand into a finer powder before discharge, thus improving the grinding effect.

[0009] Preferably, the bottom wall of the discharge trough is provided with a guide slope, which is inclined toward the axis of the discharge pipe.

[0010] By adopting the above technical solution, a guide slope is set to facilitate the entry of zircon powder into the discharge pipe, thereby improving the collection efficiency of the ground zircon powder.

[0011] Preferably, a negative pressure fan is provided on the bottom wall of the support plate.

[0012] By adopting the above technical solution, the negative pressure fan can make the powder chamber negative pressure, which facilitates the grinding of zircon powder into the discharge trough of the discharge pipe and improves the discharge efficiency of zircon powder.

[0013] Preferably, the surface of the support plate is provided with mechanical limiting.

[0014] By adopting the above technical solution, setting mechanical limiters can restrict the movement distance of the grinding block, thereby preventing the grinding block from moving excessively and causing powder to get stuck in the gap between the discharge pipe and the discharge port.

[0015] Preferably, the grinding cylinder has a maintenance port on its side wall, the grinding block includes a grinding body and a disassembly block, the grinding body has an installation groove on its side wall facing the maintenance port for the disassembly block to be inserted, and the installation groove is connected to the arc-shaped grinding surface.

[0016] By adopting the above technical solution, when the grinding ball and the arc-shaped grinding surface become stuck, the maintenance port can be opened and the disassembly block can be removed. The position of the grinding block can be adjusted by the lifting component, thereby removing the stuck large piece of material and ensuring that the grinding device of this application can operate normally.

[0017] Preferably, the sidewall of the grinding block abuts against the inner wall of the grinding cylinder, and a limiting piece is provided on the inner wall of the mounting groove near the arc-shaped grinding surface, and the disassembly block abuts against the limiting piece.

[0018] By adopting the above technical solution, the limiting piece can prevent the disassembly block from entering the range of the arc-shaped grinding surface, thereby avoiding the problem of collision between the disassembly block and the grinding ball, maintaining the stability of the disassembly block, and improving the safety of the grinding device of this application.

[0019] Preferably, the top wall of the grinding ball is provided with a conical surface to prevent material accumulation.

[0020] By adopting the above technical solution, setting a conical surface can prevent zircon powder raw materials from accumulating on the top of the grinding ball for a long time, thus affecting the overall grinding and production efficiency of zircon powder.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The staff adds zircon sand into the grinding chamber through the feed pipe. The zircon sand enters between the arc-shaped grinding surface and the grinding ball. As the grinding ball rotates, it continuously grinds the zircon sand. Due to the structural characteristics of the arc-shaped grinding surface, the zircon powder will slide towards the bottom of the arc, thereby generating more zircon powder accumulation at the bottom of the arc, achieving uniform grinding of the zircon powder, and improving grinding efficiency and grinding effect.

[0023] 2. After the zircon sand is ground, the lifting device is activated, lowering the grinding block. As a result, the discharge pipe will move relative to the grinding block, and the end of the discharge pipe with the discharge groove will come above the arc-shaped grinding surface. Due to the structure and shape of the arc-shaped grinding surface, the ground zircon powder will concentrate at the bottom of the arc. At this time, since the discharge groove is exposed, the zircon powder will enter the discharge groove and enter the powder chamber, thereby realizing the collection and control of zircon powder. This allows the grinding balls to grind the zircon sand into a finer powder before discharge, improving the grinding effect. Attached Figure Description

The rotating component 4 is a motor, and its output shaft is coaxially arranged with the rotating shaft 31. Its output shaft is inserted into the grinding chamber 11 and connected to the rotating shaft 31 to drive the grinding ball 3 to rotate, thereby achieving the purpose of grinding zircon sand.

[0029] Reference Figure 1 The grinding block 5 includes a grinding body 53 and a disassembly block 54. An arc-shaped grinding surface 51 is formed on the grinding body 53. A maintenance port 13 is formed on the side wall of the grinding cylinder 1.

The installation groove 55 is connected to the arc-shaped grinding surface 51. A limiting piece 56 is provided on the inner wall of the installation groove 55 near the arc-shaped grinding surface 51. A clearance groove is formed on the side wall of the disassembly block 54 facing the limiting piece 56 to achieve precise contact with the limiting piece 56. When a larger zircon sand particle gets stuck between the arc-shaped grinding surface 51 and the grinding ball 3, the inside of the arc-shaped grinding surface 51 can be cleaned by opening the maintenance port 13 and removing the disassembly block 54.

[0030] Reference Figure 1 and Figure 2 The grinding cylinder 1 also has a powder chamber 12 located below the grinding chamber 11. A support plate 6 is installed inside the powder chamber 12 and is located below the grinding block 5. A discharge port 52 is provided at the bottom center of the arc-shaped grinding surface 51.

The rotating component 4 is activated to drive the arc-shaped grinding surface 51 to rotate, thereby repeatedly grinding the zircon sand in the arc-shaped grinding surface 51. After grinding is completed, the lifting component 7 is activated, which drives the grinding block 5 to descend. Under relative motion, the top of the discharge pipe 8 extends out of the discharge port 52. The negative pressure fan 9 is activated, which creates a negative pressure environment in the powder chamber 12. The ground zircon powder will be collected through the discharge trough 81, thereby completing the grinding and collection of zircon powder. The arc-shaped grinding surface 51 and the discharge pipe 8 of this application can discharge the powder after fine grinding of the zircon sand, which improves the grinding quality of zircon powder.
