Description

Technical Field

[0001] This utility model belongs to the field of zinc-aluminum-magnesium alloy powder processing technology, specifically relating to a grinding device for ultra-corrosion-resistant zinc-aluminum-magnesium alloy powder. Background Technology

[0002] The zinc-aluminum-magnesium alloy powder grinding device is used to grind the hard alloy of zinc-aluminum-magnesium alloy into powder.

[0003] Publication No. CN217912848U, Publication Date 20221129, discloses a cemented carbide powder grinding device, including an installation structure. The installation structure includes a shell, a grinding groove is formed on the inner wall of the shell, a guide ring is fixedly connected to the top of the inner wall of the shell, a connecting rod is welded to the top of the inner wall of the shell, a slider is fixedly connected to one end of the connecting rod, a horizontal plate is welded to the top of the shell, a filter screen is provided at the bottom of the shell, and a guide plate is provided at the bottom of the shell directly below the filter screen.

[0004] In the prior art, including the aforementioned patent, powder is filtered and screened by setting up a filter screen and then re-grinded to improve the uniformity of the powder. However, the filter screen is stationary during filtration, and the powder tends to accumulate on the filter screen and cannot be discharged. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a grinding device for ultra-corrosion resistant zinc-aluminum-magnesium alloy powder.

[0006] The technical solution adopted to solve the above technical problems is: a grinding device for ultra-corrosion resistant zinc-aluminum-magnesium alloy powder, including a body, wherein a grinding mechanism, a screening mechanism and an anti-clogging mechanism are provided on the body;

[0007] The screening mechanism includes a fixed plate fixedly mounted on the outer wall of the main body. A second motor is fixedly installed on the lower surface of the fixed plate. A second rotating shaft is fixedly connected to the output end of the second motor. A turntable is fixedly connected to the top end of the second rotating shaft. A screening screen is slidably mounted on the main body. Limiting plates are fixedly mounted at both ends of the screening screen that pass through the main body. A connecting rod is hinged to the edge of the upper surface of the turntable at the limiting plate near the fixed plate end of the screening screen.

[0008] Through the above technical solution, the ground powder falls onto the screening screen through the discharge port at the bottom of the grinding cylinder. The second motor is started and drives the turntable to rotate through the second rotating shaft. This, in turn, drives the screening screen to move back and forth on the main body through the connecting rod, thereby screening the powder falling on the screening screen. The back and forth movement of the screening screen enables the powder to be screened quickly, effectively preventing the powder from accumulating on the screening screen and affecting the feeding.

[0009] Furthermore, the grinding mechanism includes a grinding cylinder fixedly mounted on the top of the main body, a first motor fixedly mounted on the top of the grinding cylinder, a first rotating shaft fixedly connected to the output end of the first motor, a grinding roller fixedly connected to the bottom end of the first rotating shaft, and a first grinding protrusion arrayed on the surface of the grinding roller.

[0010] Furthermore, the inner wall of the grinding cylinder is provided with an array of second grinding protrusions, which are spaced apart from the first grinding protrusions.

[0011] The above technical solution involves feeding aluminum-magnesium alloy into the grinding cylinder through the feed inlet at the top of the grinding cylinder. The alloy enters the grinding cylinder and falls into the gap between the grinding roller and the grinding cylinder. The first motor is started, which drives the grinding roller to rotate through the first rotating shaft. This causes the first grinding protrusion on the grinding roller to rotate relative to the second grinding protrusion on the grinding cylinder. Thus, the alloy is ground under the combined action of the first and second grinding protrusions. The spaced second grinding protrusions and the first grinding protrusions allow the alloy to be repeatedly ground as it moves downward, effectively improving the grinding accuracy and grinding effect.

[0012] Furthermore, the grinding cylinder is provided with a feed inlet and a discharge outlet at its top and bottom, respectively.

[0013] Furthermore, the anti-blocking mechanism includes a connecting frame on which a striking hammer is fixedly mounted.

[0014] Furthermore, support legs are fixedly installed at the four corners of the bottom of the main body, a material discharge port is provided at the bottom of the main body, and a recycling door is provided on the main body.

[0015] Furthermore, the connecting frame is fixed to the limiting plate at the end of the screening net away from the fixed plate, and the position of the hammer is set corresponding to the discharge port.

[0016] Through the above technical solution, during the back-and-forth movement of the screening screen, the connecting frame drives the hammer to repeatedly strike the outer wall of the discharge port, thereby causing vibration at the discharge port, so that the powder can be discharged smoothly and avoid blockage of the discharge port. Moreover, there is no need for an additional drive source to drive the hammer to repeatedly strike the discharge port, effectively saving equipment costs.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) With the turntable and connecting rod set in this utility model, the ground powder falls onto the screen through the discharge port at the bottom of the grinding cylinder. The second motor is started and drives the turntable to rotate through the second rotating shaft, thereby driving the screen to move back and forth on the main body through the connecting rod, so as to screen the powder falling on the screen. The screen can move back and forth, thereby quickly screening the powder and effectively avoiding the accumulation of powder on the screen that affects the feeding.

[0019] (2) The present invention uses the second grinding protrusion and the first grinding protrusion to feed the aluminum-magnesium alloy into the grinding cylinder through the feed port at the top of the grinding cylinder. The alloy enters the grinding cylinder and falls into the gap between the grinding roller and the grinding cylinder. The first motor is started to drive the grinding roller to rotate through the first rotating shaft, thereby driving the first grinding protrusion on the grinding roller to rotate relative to the second grinding protrusion on the grinding cylinder. Thus, the alloy is ground under the combined action of the first grinding protrusion and the second grinding protrusion. Through the second grinding protrusion and the first grinding protrusion set at intervals, the alloy can be repeatedly ground multiple times during the downward movement, which effectively improves the grinding accuracy and grinding effect.

[0020] (3) The present invention uses a hammer to repeatedly strike the outer wall of the discharge port through the connecting frame during the back-and-forth movement of the screening screen, thereby causing vibration at the discharge port, so that the powder can be discharged smoothly, avoiding blockage of the discharge port, and without the need for an additional drive source to drive the hammer to repeatedly strike the discharge port, effectively saving equipment costs.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figure 1-5 As shown, the ultra-corrosion resistant zinc-aluminum-magnesium alloy powder grinding device of this embodiment includes a body 1, on which a grinding mechanism 2, a screening mechanism 4 and an anti-blocking mechanism 7 are provided.

[0029] The screening mechanism 4 includes a fixed plate 47 fixedly mounted on the outer wall of the main body 1. A second motor 46 is fixedly mounted on the lower surface of the fixed plate 47. A second rotating shaft 45 is fixedly connected to the output end of the second motor 46. A turntable 44 is fixedly connected to the top end of the second rotating shaft 45. A screening screen 41 is slidably mounted on the main body 1. Limiting plates 42 are fixedly mounted at both ends of the screening screen 41 that pass through the main body 1. A connecting rod 43 is hinged to the edge of the upper surface of the turntable 44 at the limiting plate 42 near the fixed plate 47 of the screening screen 41, which enables the screening screen 41 to move back and forth, thereby quickly screening the powder and effectively preventing the powder from accumulating on the screening screen 41 and affecting the feeding.

[0030] The grinding mechanism 2 includes a grinding cylinder 21 fixedly mounted on the top of the main body 1. A first motor 22 is fixedly mounted on the top of the grinding cylinder 21. A first rotating shaft 28 is fixedly connected to the output end of the first motor 22. A grinding roller 24 is fixedly connected to the bottom end of the first rotating shaft 28. A first grinding protrusion 25 is arrayed on the surface of the grinding roller 24.

[0031] The inner wall of the grinding cylinder 21 is provided with an array of second grinding protrusions 26, which are spaced apart from the first grinding protrusions 25. The spaced second grinding protrusions 26 and the first grinding protrusions 25 enable the alloy to be repeatedly ground during the downward movement, effectively improving the grinding accuracy and grinding effect.

[0032] The grinding cylinder 21 is provided with a feed inlet 23 and a discharge outlet 27 at the top and bottom, respectively.

[0033] The anti-blocking mechanism 7 includes a connecting frame 72, on which a hammer 71 is fixedly installed. The hammer 71 can repeatedly strike the discharge port 5, thereby causing the discharge port 5 to vibrate and allowing the powder to fall smoothly, effectively preventing the discharge port 5 from becoming blocked.

[0034] Support legs 6 are fixedly installed at the four corners of the bottom of the main body 1, a discharge port 5 is provided at the bottom of the main body 1, and a recycling door 3 is provided on the main body 1.

[0035] The connecting frame 72 is fixedly connected to the limiting plate 42 at the end of the screening screen 41 away from the fixed plate 47. The position of the hammer 71 is set to correspond to the feeding port 5. There is no need for an additional driving source to drive the hammer 71 to repeatedly strike the feeding port 5, which effectively saves equipment costs.

[0036] The working principle of this embodiment is as follows: Aluminum-magnesium alloy is fed into the grinding cylinder 21 through the feed inlet 23 at the top of the grinding cylinder 21. The alloy enters the grinding cylinder 21 and falls into the gap between the grinding roller 24 and the grinding cylinder 21. The first motor 22 is started, driving the grinding roller 24 to rotate via the first rotating shaft 28. This causes the first grinding protrusion 25 on the grinding roller 24 to rotate relative to the second grinding protrusion 26 on the grinding cylinder 21. Thus, the alloy is ground under the combined action of the first grinding protrusion 25 and the second grinding protrusion 26. The ground powder falls onto the screening screen 41 through the discharge outlet 27 at the bottom of the grinding cylinder 21. The second motor 22 is then started. Motor 46 drives turntable 44 to rotate via second shaft 45, which in turn drives screen 41 to move back and forth on body 1 via connecting rod 43, thereby screening the powder falling on screen 41. Qualified powder falls through screen 41 and is collected through discharge port 5 at the bottom of body 1. Larger powder remains on screen 41 to be recycled and re-ground. At the same time, during the back and forth movement of screen 41, the connecting frame 72 drives hammer 71 to repeatedly strike the outer wall of discharge port 5, thereby causing vibration at discharge port 5, so that the powder can be discharged smoothly and avoid clogging of discharge port 5.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
