Description

Technical Field

[0001] The present invention relates to the technical field of screening and collection equipment, and particularly relates to a magnesium ingot chip collection device. Background Art

[0002] In the prior art, magnesium powder processing requires a chip cutter with a cutter roller to process magnesium ingots into magnesium chips, and then the magnesium chips are crushed to form magnesium powder. Magnesium powder has a smaller particle size than magnesium chips and is more likely to oxidize and reach the critical conditions for combustion or explosion when in contact with air. Therefore, the storage conditions for magnesium powder are more stringent than those for magnesium chips. If magnesium powder is mixed with magnesium chips and stored according to the storage conditions of magnesium chips, it may cause a fire or explosion due to static electricity, friction, or high temperature.

[0003] Chinese Patent Application with Publication No. CN117817046A discloses a sawing machine with a magnesium chip collection mechanism, including a sawing bed, a sawing machine body, a collection assembly, a cooling assembly, and a water blowing assembly. The collection assembly includes a funnel frame, two U-shaped frames, two sliding plates, a collection frame, an inclined plate, support columns, universal wheels, a handle, and a frosted sleeve. The cooling assembly includes a mounting frame, a pressure booster, a water pipe, a nozzle, a valve, and a water storage tank. The water blowing assembly includes a blower, a hose, and a snap ring. The sawing machine body is detachably connected to the sawing bed and is located above the sawing bed. The collection assembly is arranged below the sawing bed. When the sawing machine body works, the generated magnesium alloy chips slowly roll from the funnel frame onto the inclined plate and then slowly roll into the collection frame, completing the collection of magnesium alloy chips.

[0004] The problems existing in the above-mentioned sawing machine with a magnesium chip collection mechanism during use are as follows: During the process of the sawing machine body processing magnesium ingots into magnesium chips, the cutter roller and the magnesium ingots rub violently, which will cause the surface temperature of the magnesium chips to rise, and some magnesium chips will form magnesium powder due to high-temperature oxidation or mechanical crushing. The magnesium alloy chips processed by the sawing machine contain magnesium powder, which may cause a fire or explosion due to static electricity, friction, or high temperature during storage. Summary of the Invention

[0005] The present invention provides a magnesium ingot chip collection device, aiming to solve the problem that the magnesium chips processed by the sawing machine with a magnesium chip collection mechanism in the above-mentioned prior art contain magnesium powder, which may cause a fire or explosion due to static electricity, friction, or high temperature during storage.

The vibration component is used to drive the screen mesh to vibrate. The box body is provided with a material inlet and a magnesium chip outlet. The material inlet is located above the screen mesh. When the mixed material of magnesium chips and magnesium powder is conveyed into the box body, it can fall on the screen mesh. When the screen mesh vibrates, it can drive the magnesium chips to move towards the magnesium chip outlet. When the magnesium chips are discharged through the magnesium chip outlet, they can fall into the magnesium chip collection box; the blowing component is used to output an upward separation air flow. When the separation air flow passes through the screen mesh, it can carry the magnesium powder upwards, so that the magnesium powder is separated from the magnesium chips. The magnesium powder collection component is located above the screen mesh, and the separation air flow can carry the magnesium powder into the magnesium powder collection component.

The mixed material falls on the screen mesh. The vibration component drives the screen mesh to vibrate. During the vibration of the screen mesh, the magnesium chips and the magnesium powder are separated. The separation air flow output by the blowing component moves upwards and carries the magnesium powder into the magnesium powder collection component. In addition, when the screen mesh vibrates, it drives the magnesium chips to move towards the magnesium chip outlet and is discharged through the magnesium chip outlet and falls into the magnesium chip collection box, realizing the separation and collection of magnesium chips and magnesium powder, thereby preventing fires or explosions that may be caused by static electricity, friction or high temperature during storage due to the presence of magnesium powder in the magnesium chips.

When the mixed material of magnesium chips and magnesium powder is conveyed into the box body 31 through the material inlet 311, it can fall onto the screen 32. When the screen 32 vibrates, it can drive the magnesium chips to move towards the magnesium chip outlet 312 and be discharged from the magnesium chip outlet 312. When the magnesium chips are discharged through the magnesium chip outlet 312, they can fall into the magnesium chip collection box 1. The blowing assembly 5 is located below the screen 32. The blowing assembly 5 is used to output an upward separation air flow. When the separation air flow passes through the screen 32, it can carry the magnesium powder upward, so that the magnesium powder is separated from the magnesium chips. The magnesium powder collection assembly is located above the screen 32, and the separation air flow can carry the magnesium powder into the magnesium powder collection assembly.

[0041] As Figures 5 - 10 shown, the vibration assembly includes a lifting driving member 41, a transmission member 42, and a mounting frame 43. The mounting frame 43 includes a frame 431 and an intermediate plate 432. The intermediate plate 432 is located at the center of the frame 431, and both ends of the intermediate plate 432 are respectively fixed on two opposite sides of the frame 431. The intermediate plate 432 divides the area surrounded by the frame 431 into two mounting grooves 433. The frame 431 is vertically slidably arranged inside the box body 31.

The magnesium chip outlet 312 is located on the side of the frame 431 far from the material inlet 311. There are two screens 32, which are respectively located in the two mounting grooves 433. The circumferential surface of the screen 32 is attached to the circumferential groove wall of the mounting groove 433. Two vertical pressing plates 44 are fixedly arranged at intervals at the bottom of the intermediate plate 432.

[0042] As Figures 11 - 15 shown, the transmission member 42 includes a vertical sliding plate 421, a telescopic support member 422, and a vibration elastic member 423.

The upper surface of the overhanging ends is set as a first extrusion inclined surface 42211, and the two first extrusion inclined surfaces 42211 are in a V-shape. The two extrusion plates 44 are respectively located above the two overhanging ends and supported on the first extrusion inclined surfaces 42211. When the two extrusion plates 44 move downward relative to the vertical slide plate 421, they can extrude the two first extrusion inclined surfaces 42211, causing the two overhanging ends to retract into the horizontal mounting holes.

[0044] As Figures 6 - 11 shown, a shaft hole 4322 is formed in the intermediate plate 432, and a mounting shaft 434 is rotatably disposed in the shaft hole 4322.

[0048] As Figure 1 , Figure 3 and Figure 5 shown, the magnesium powder collection assembly includes a magnesium powder collection box 21 and a suction fan (not shown in the figure). The magnesium powder collection box 21 is fixedly arranged on the outer wall of the upper side of the box body 31. Magnesium powder outlets 315 are respectively opened on the chamber walls of the first magnesium powder chamber 313 and the second magnesium powder chamber 314. A magnesium powder inlet is opened on the magnesium powder collection box 21, and the magnesium powder inlet is communicated with the magnesium powder outlet 315. The suction fan is fixedly arranged in the magnesium powder collection box 21, and the suction fan is used to suck the magnesium powder in the first magnesium powder chamber 313 and the second magnesium powder chamber 314 into the magnesium powder collection box 21.

[0049] The implementation principle of the magnesium ingot chip collection device according to the embodiment of the present invention is as follows: During use, the mixed material of magnesium chips and magnesium powder is conveyed into the box body 31 through the material inlet 311. The mixed material falls onto the screen 32. The lifting drive member 41 drives the guide plate 7 to drive the vertical sliding plate 421 to move upward. When the vertical sliding plate 421 moves upward, it will push the extrusion plate 44 and the mounting frame 43 upward through the support slider 4221, thereby driving the screen 32 to move upward. During the upward movement of the mounting frame 43, the vibration elastic member 423 is stretched. When the vibration elastic member 423 is stretched sufficiently, the extrusion plate 44 squeezes the overhanging end of the support slider 4221 back into the horizontal mounting hole. At this time, the mounting frame 43 moves downward and resets under the pulling force of the vibration elastic member 423, and then the lifting drive member 41 drives the vertical sliding plate 421 to move downward and reset, realizing the up-and-down vibration of the screen 32.

[0050] During the process of the mounting frame 43 moving downward and resetting under the pulling force of the vibration elastic member 423, the vertical sliding plate 421 does not move downward. Therefore, the second driving gear 62 moves downward relative to the first rack 424, and the first rack 424 drives the second driving gear 62 to rotate reciprocally, thereby driving the screen 32 to rotate up and down reciprocally. During the process of the lifting drive member 41 driving the vertical sliding plate 421 to move downward and reset, the first rack 424 moves downward relative to the second driving gear 62, and the first rack 424 drives the second driving gear 62 to rotate reciprocally, thereby driving the screen 32 to rotate up and down reciprocally.

[0051] During the vibration of the screen 32, the magnesium chips and magnesium powder are separated. The separation air flow output by the blower 51 enters the guide plate 7 through the ventilation pipe 52, then enters the air dispersion pipe 53, and then is discharged upward through the air outlet holes on the air dispersion pipe 53. The separation air flow carries the magnesium powder upward and contacts the adsorption belt 93. The magnesium powder is adsorbed on the adsorption belt 93. Then, the first winding drum 91 winds up the adsorption belt 93, and the second winding drum 92 unwinds the adsorption belt 93. The adsorption belt 93 adsorbed with magnesium powder moves above the first magnesium powder chamber 313. Then, the first reverse blower 95 blows the magnesium powder adsorbed on the adsorption belt 93 into the first magnesium powder chamber 313, and the suction fan sucks the magnesium powder in the first magnesium powder chamber 313 into the magnesium powder collection box 21. Or, the first winding drum 91 unwinds the adsorption belt 93, and the second winding drum 92 winds up the adsorption belt 93. The adsorption belt 93 adsorbed with magnesium powder moves above the second magnesium powder chamber 314. Then, the second reverse blower 97 blows the magnesium powder adsorbed on the adsorption belt 93 into the second magnesium powder chamber 314, and the suction fan sucks the magnesium powder in the second magnesium powder chamber 314 into the magnesium powder collection box 21. When the screen 32 vibrates, it drives the magnesium chips to move towards the magnesium chip outlet 312 and is discharged through the magnesium chip outlet 312 and falls into the magnesium chip collection box 1, realizing the separation and collection of magnesium chips and magnesium powder, thereby preventing fires or explosions that may be caused by static electricity, friction or high temperature during storage due to the presence of magnesium powder in the magnesium chips.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
