Description

Technical Field

[0001] This utility model relates to a briquetting machine for processing magnesium-aluminum alloys, belonging to the technical field of briquetting machine tools. Background Technology

[0002] Magnesium-aluminum alloy briquetting machines are mainly used to compress powdered materials into spherical shapes. Their structure is as follows: Figure 7 As shown, this equipment is suitable for various industrial applications. Its main functions include dust reduction, density control, recycling, and improved transport characteristics. This equipment plays a crucial role in the pelletizing and agglomeration process of non-ferrous and ferrous metal ore powders, allowing for direct smelting in furnaces and increasing the added value of the products.

[0003] Existing briquetting machines for magnesium-aluminum alloy processing have issues during use. Due to factors such as working environment and humidity, materials with varying viscosities may adhere to the inner wall of the briquetting groove, resulting in uneven surfaces on the pressed magnesium-aluminum alloy balls. In severe cases, this affects the subsequent briquetting quality, manifesting as the pressed magnesium-aluminum alloy balls easily breaking apart during transportation.

[0004] There is a need for a briquetting machine for processing magnesium-aluminum alloys that can solve the problem of residual material on the inner wall of the briquetting groove during the pressing process, so as to ensure the quality of the subsequently pressed alloy balls. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a briquetting machine for processing magnesium-aluminum alloys, which can solve the problem of residual material on the inner wall of the briquetting groove during the pressing process, so as to ensure the quality of the subsequently pressed alloy balls; and can overcome the shortcomings of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] This utility model discloses a briquetting machine for processing magnesium-aluminum alloys. It includes a briquetting machine body, a feeding device at the upper end of the briquetting machine body, a pair of briquetting rollers inside the briquetting machine body, briquetting grooves distributed on the outer wall of the rollers, the rollers being connected to a drive device, a product conveyor belt on the briquetting machine body, an air outlet pipe at the bottom of the briquetting machine body, an air outlet hole for spraying air onto the outer wall of the rollers on the air outlet pipe, the air outlet pipe being connected to an inert gas conveying pipe, the inert gas conveying pipe being connected to an inert gas pressure tank, and a pressurization device on the inert gas pressure tank.

[0008] The above-mentioned air outlet is a strip-shaped air outlet arranged along the longitudinal direction of the air outlet pipe, and the strip-shaped air outlet corresponds one-to-one with the pressure ball groove.

[0009] The inert gas mentioned above is nitrogen.

[0010] The aforementioned device also includes an angle adjustment device for adjusting the direction of the air outlet of the air pipe.

[0011] The aforementioned angle adjustment device includes a positioning hole at the end of the air outlet pipe on the inner wall of the briquetting machine body, an insertion hole for the air outlet pipe on the side wall on the other side of the briquetting machine body, a positioning plate for the outer end of the air outlet pipe on the outer side of the briquetting machine body, a locking hole and a locking pin on the positioning plate, an annular plate fixed on the air outlet pipe, a locking hole on the annular plate that cooperates with the locking pin, and the air outlet pipe being connected to an inert gas conveying pipe.

[0012] As mentioned above, the briquetting machine body is equipped with side sealing plates on both the front and rear sides.

[0013] As mentioned above, a transparent observation window is provided on the side sealing plate.

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

[0015] 1. This utility model uses an air outlet pipe to blow air onto the inner wall of the briquetting groove, thereby blowing off the material adhering to the inner wall of the briquetting groove and ensuring the quality of the subsequent pressed alloy balls. Specifically, the air outlet pipe is located at the bottom of the briquetting machine body and the air outlet faces upward toward the roller, which also helps to blow off the material adhering to the inner wall of the briquetting groove. Moreover, the gas used is an inert gas, which helps to reduce the oxidation of magnesium powder due to contact with oxygen during the pressing process.

[0016] 2. The air outlet is a strip-shaped air outlet arranged along the longitudinal direction of the air outlet pipe. The strip-shaped air outlet corresponds one-to-one with the briquetting groove. In this way, the air outlet blows air into the briquetting groove, forming a linear air outlet. During the rotation of the roller, a blowing surface is formed on the roller. The line blows the surface, thereby blowing off the material stuck to the inner wall of the briquetting groove.

[0017] 3. The position of the air outlet pipe can be rotated by the angle adjustment device, thereby adjusting the angle of the air outlet hole of the air outlet pipe relative to the roller. After the angle is adjusted, the pipe is positioned by the locking pin and the locking hole. In use, after adjusting the angle of the air outlet pipe, the inert gas delivery pipe is connected to the air outlet pipe.

[0018] 4. The briquetting machine body is equipped with side sealing plates on both the front and rear sides. The side sealing plates help to form an inert atmosphere in the briquetting machine body, and excess air is discharged from the bottom product conveyor belt, which helps to reduce the oxygen in the briquetting machine body, reduce the oxidation of magnesium powder by oxygen, and improve the pressing effect of magnesium-aluminum alloy.

[0019] 5. A transparent observation window is provided on the side sealing plate. This structure allows for observation of the effect of gas blowing and spraying on the roller to remove surface adhesive.

The inert gas conveying pipe is connected to an inert gas... The pressure tank is connected, and the inert gas pressure tank is equipped with a pressurization device. The inert gas is nitrogen. With this structure, by setting the vent pipe 7, the gas is blown onto the inner wall of the briquetting groove 4 to blow off the material adhering to the inner wall of the briquetting groove 4, so as to ensure the quality of subsequent pressing of alloy balls. Specifically, the vent pipe 7 is set at the bottom of the briquetting machine body 1 and the vent hole 8 faces upward toward the roller 3, which also helps to blow off the material adhering to the inner wall of the briquetting groove 4. Moreover, the gas used is an inert gas, which helps to reduce the oxidation of magnesium powder due to contact with oxygen during the pressing process.

[0033] Furthermore, the air outlet 8 is a strip-shaped air outlet arranged along the longitudinal direction of the air outlet pipe 7. The strip-shaped air outlet corresponds one-to-one with the ball-pressing groove 4. In this way, the air outlet blows air into the ball-pressing groove 4, forming a linear air outlet. During the rotation of the roller 3, a blowing surface is formed on the roller 3. The line blows the surface, thereby blowing off the material stuck to the inner wall of the ball-pressing groove 4.

After the angle is adjusted, it is positioned by the locking pin 11 and the locking hole 13. In use, after adjusting the angle of the air pipe 7, the inert gas delivery pipe is connected to the air pipe 7.
