[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a dust-proof grinding device for magnesium powder production;

[0023] It includes a No. 1 shell 1, a No. 2 shell 6 and a supporting shell 15. A No. 1 motor 3 is arranged on the back of the No. 1 shell 1, and a crushing component 4 is arranged at the output end of the No. 1 motor 3. A No. 1 filter 5 is arranged inside the No. 1 shell 1, and the No. 1 filter 5 is located below the crushing component 4. A No. 2 motor 11 is arranged on the back of the No. 2 shell 6, and a grinding component 12 is arranged at the output end of the No. 2 motor 11. An arc-shaped grinding plate 8 is movably connected inside the No. 2 shell 6, and the arc-shaped grinding plate 8 is located below the grinding component 12. Two groups of discharge troughs 13 are symmetrically opened inside the No. 2 shell 6, and a No. 2 filter 14 is detachably connected inside the discharge trough 13.

[0024] The crushing assembly 4 is composed of a connecting shaft and a spherical rod. When the No. 1 motor 3 is running, the crushing assembly 4 can rotate inside the No. 1 shell 1 to perform a rotary crushing process on the raw material block magnesium powder placed on the top of the No. 1 filter 5. The No. 1 filter 5 can be used to make the magnesium blocks that meet the body shape after crushing fall to the top of the arc-shaped grinding plate 8 of the No. 2 shell 6. The crushing assembly 4 and the No. 1 filter 5 can be used together to pre-crush the raw material block magnesium powder. The arc-shaped grinding plate 8 and the grinding assembly 12 are staggered, and the gap between the arc-shaped grinding plate 8 and the grinding assembly 12 is small. When the No. 2 motor 11 is running, the grinding component 12 can be made to swing back and forth 180 degrees inside the No. 2 shell 6. The grinding component 12 and the arc-shaped grinding plate 8 can be used to grind the crushed bulk raw material pulverized coal. Through the swing of the grinding component 12, the magnesium powder that meets the specifications after grinding can pass through the No. 2 filter screen 14 and enter the interior of the discharge chute 13. The No. 2 filter screen 14 is detachably connected to the interior of the No. 2 shell 6, so that the No. 2 filter screen 14 can be flexibly replaced according to the use requirements and the grinding accuracy requirements of the magnesium powder, thereby effectively improving the grinding efficiency of the grinding device.

[0025] like Figure 1 and Figure 3 As shown, a dust-proof grinding device for magnesium powder production;

[0026] The top of the No. 1 shell 1 is detachably connected to a top cover 2, the front of the No. 1 shell 1 is provided with an inert gas box 18, the front of the inert gas box 18 is connected to an air suction pump 19, the output end of the air suction pump 19 is provided with a delivery pipe 20, and the delivery pipe 20 passes through the inner walls of the No. 1 shell 1 and the No. 2 shell 6 respectively.

[0027] Shell No. 1 is one of the main combined shells of the grinding device. By operating the suction pump 19, the inert gas stored in the inert gas box 18 can be transported to the interior of shell No. 1 and shell No. 2 6 through the delivery pipe 20. By injecting inert gas into the interior of shell No. 1 and shell No. 2 6 to isolate the air, magnesium powder is prevented from contacting with the outside air, thereby playing a dust-proof role.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a dust-proof grinding device for magnesium powder production;

[0029] The front of the No. 2 shell 6 is detachably connected to the No. 1 sealing door 7, and the No. 1 sealing door 7 is located in front of the arc-shaped grinding plate 8. Two groups of connecting plates 9 are provided at the bottom end of the arc-shaped grinding plate 8. The inner wall of the No. 2 shell 6 is provided with two groups of limiting shells 10, and the limiting shells 10 are L-shaped plates. The connecting plates 9 are movably located inside the limiting shells 10.

[0030] The connecting plate 9 is installed at the bottom end of the arc-shaped grinding plate 8 through a symmetrical connection, and then symmetrically arranged on the inner wall of the No. 2 shell 6 through a limiting shell 10, and the connecting plate 9 is movably arranged inside the limiting shell 10. The limiting shell 10 can support the arc-shaped grinding plate 8, and the arc-shaped grinding plate 8 can be replaced later by disassembling the No. 1 sealing door 7.

A collecting shell 17 is movably arranged inside the support shell 15, and the collecting shell 17 is located below the through grooves 16. The collecting shell 17 passes through the front of the support shell 15.

[0033] The support shell 15 provides an installation storage space for the internal collection shell 17 . The through slot 16 is opened through the top of the support shell 15 , and the through slot 16 is connected to the inside of the feed chute 13 . The magnesium powder dropped from the inside of the feed chute 13 can be stored in the collection shell 17 .

[0034] Before use, the raw material block magnesium powder is placed on the top of the No. 1 filter 5, and the top cover 2 is sealed and connected to the top of the No. 1 shell 1. When the No. 1 motor 3 is running, the raw material block magnesium powder can be pre-crushed by using the crushing component 4 and the No. 1 filter 5.
