Description

Technical Field

[0001] The present invention relates to the technical field of aluminum powder preparation, and particularly relates to an atomization preparation device for fine aluminum powder. Background Art

[0002] The ultrasonic metal powder preparation technology has the advantages of high purity, low oxygen content, good sphericity and uniform particle size. Standing waves are generated on the ultrasonic vibration disk, and the molten metal liquid is sprayed on the ultrasonic vibration disk. The molten metal liquid will be broken into uniform micron-sized droplet fine mist to achieve atomization. The micron-sized droplets after atomization are thrown out of the atomization surface under the action of the rotational centrifugal force and standing waves of the ultrasonic vibration disk, and are quickly solidified by air cooling to form micron-sized metal solid particles.

[0003] When the existing ultrasonic metal powder preparation equipment is in use, in order to ensure that there is no residual aluminum liquid on the ultrasonic vibration disk, resulting in the solidification of aluminum liquid on the ultrasonic vibration disk, the spraying flow rate of the molten metal is relatively low. Although this can produce aluminum powder with better quality, the production efficiency is low. And when the solidified aluminum liquid on the ultrasonic vibration disk is too thick, it will lead to a reduction in the quality of powder preparation, and it needs to be frequently cleaned by staff, resulting in a further reduction in production efficiency.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1 An atomization preparation device for fine aluminum powder, as Figures 1 - 5 shown, includes a box body 1. An ultrasonic vibrating disk 101 is rotatably connected to the top inside the box body 1. It further includes a detection mechanism. The detection mechanism includes a bracket 201. The bracket 201 is fixedly connected to the left side of the inner wall of the box body 1. A round tube 202 is arranged below the bracket 201. The bottom end of the round tube 202 communicates with a mounting bracket 203. The bottom of the mounting bracket 203 is hinged with a flexible plate 204. When there is solidified aluminum remaining on the surface of the ultrasonic vibrating disk 101, the flexible plate 204 can contact the aluminum. The bottom of the mounting bracket 203 communicates with a balloon 205. As the thickness of the remaining aluminum on the surface of the ultrasonic vibrating disk 101 increases, the flexible plate 204 can squeeze the balloon 205. It further includes an adjustment mechanism. The adjustment mechanism includes a telescopic rod 206. The telescopic rod 206 is fixedly connected to one side of the bracket 201. An injection tube 207 is arranged below the telescopic rod 206. When the balloon 205 is squeezed, the injection tube 207 can move.

[0021] As Figure 4 shown in Figure 5 connection with

[0022] shown, the detection mechanism further includes a sliding tube 301. The sliding tube 301 is slidably connected to the inner wall of the round tube 202. When the balloon 205 is squeezed, the sliding tube 301 can move. Figure 4As shown, an electromagnet 401 is also included. The top of the round tube 202 is fixedly mounted with the electromagnet 401 . The electromagnet 401 is fixedly connected to the bracket 201 . When the distance between the sliding tube 301 and the electromagnet 401 is short, the electromagnet 401 can generate suction on the sliding tube 301 .

[0023] like Figure 4 and Figure 6 As shown, the adjustment mechanism also includes an air pipe 501, the left side of the circular tube 202 is connected to the air pipe 501, a hose is commonly connected between the air pipe 501 and the telescopic rod 206, a guide rail 502 is fixedly connected to the bracket 201, a sliding plate 503 is slidably connected inside the guide rail 502, the injection pipe 207 is fixedly connected to the sliding plate 503, the telescopic end of the telescopic rod 206 is fixedly connected to the sliding plate 503, and when the sliding tube 301 moves, the telescopic end of the telescopic rod 206 can be extended.

[0024] like Figure 6 As shown, the adjustment mechanism also includes an airbag 601. The outer wall of the fixed end of the telescopic rod 206 is connected to the airbag 601. The inner wall of the fixed end of the telescopic rod 206 is embedded with a damping strip, and the telescopic end of the telescopic rod 206 is fitted with the damping strip. When there is too much air in the telescopic rod 206, the airbag 601 can expand, thereby preventing the telescopic end of the telescopic rod 206 from moving too fast.

[0025] Initially, the telescopic end of the telescopic rod 206 is in a contracted state, and the flexible plate 204 is in a vertical state. First, drive the ultrasonic vibrating disk 101 to rotate through a driving device in the prior art (the driving device is in the prior art and is not shown in the figure, so it will not be elaborated here), and start the ultrasonic vibrating disk 101. Then, feed the molten aluminum liquid into the injection pipe 207 through a feeding device in the prior art (the feeding device is in the prior art and is not shown in the figure, so it will not be elaborated here). The aluminum liquid is ejected through the injection pipe 207 and lands on the top surface of the ultrasonic vibrating disk 101. At this time, the flow rate of the aluminum liquid ejected from the injection pipe 207 is much larger than that of the aluminum liquid ejected in the prior art ultrasonic metal powder-making equipment. Thus, the powder-making efficiency can be greatly improved. However, directly increasing the flow rate of the ejected aluminum liquid will cause some aluminum liquid to solidify on the ultrasonic vibrating disk 101, and the solidified aluminum will cause the vibration of the ultrasonic vibrating disk 101 to be uneven or blocked. At this time, the position of the injection pipe 207 needs to be adjusted to increase the falling time of the aluminum liquid in the air. The aluminum liquid is broken into a uniform fine mist of micron-sized liquid droplets under the action of the ultrasonic vibrating disk 101 to achieve atomization. The atomized aluminum liquid is quickly solidified when it meets the air and forms micron-sized metal solid particles, and then flies towards the rear side of the inner wall of the box body 1. Subsequently, it falls under the influence of its own weight. Due to the large injection flow rate of the aluminum liquid, as the aluminum liquid is continuously ejected onto the surface of the ultrasonic vibrating disk 101, some aluminum liquid will remain and solidify on the top surface of the ultrasonic vibrating disk 101 and gradually thicken. When the thickness of the aluminum reaches a certain level, the bottom of the flexible plate 204 will contact the aluminum. The flexible plate 204 rotates around the connection point of the mounting frame 203 under the frictional action of the aluminum. At this time, the flexible plate 204 squeezes the balloon 205. It should be noted that the elastic force of the balloon 205 is small. When the flexible plate 204 squeezes the balloon 205, the reaction force exerted by the balloon 205 on the flexible plate 204 is small, and the flexible plate 204 will not exert a large squeezing force on the aluminum, and the vibration frequency of the ultrasonic vibrating disk 101 will not be affected. Thus, it can ensure that the formed aluminum powder has a uniform particle size. After the balloon 205 is stressed and shrinks, the air inside the balloon 205 enters the corresponding circular tube 202 through the mounting frame 203. The air between the sliding tube 301 in the circular tube 202 and the mounting frame 203 increases, and the sliding tube 301 is pushed by the air to slide upward along the inner wall of the circular tube 202. At this time, the air between the top end of the sliding tube 301 and the circular tube 202 is squeezed, and the air enters the inner cavity of the telescopic rod 206 through the air delivery pipe 501 and the hose. The telescopic end of the telescopic rod 206 is extended by the air push and drives the sliding plate 503 to slide along the guide rail 502. The sliding plate 503 drives the injection pipe 207 to move towards the side close to the center of the ultrasonic vibrating disk 101, increasing the falling time of the aluminum liquid ejected from the injection pipe 207 in the air, which helps the further fragmentation and atomization of the aluminum liquid. It should be noted that after the injection pipe 207 moves, the landing point of the ejected aluminum liquid on the ultrasonic vibrating disk 101 remains unchanged. As the aluminum liquid solidifies, protrusions will appear on the surface of the solidified aluminum. When the flexible plate 204 is squeezed by the protrusions on the aluminum surface,The flexible plate 204 will rotate instantaneously and rapidly, and instantaneously and rapidly squeeze the balloon 205, thereby suddenly increasing the air in the inner cavity of the telescopic rod 206. At this time, by fitting the damping strip to the outer wall of the telescopic end of the telescopic rod 206, a frictional force can be applied to the telescopic end of the telescopic rod 206, thereby restricting the extension speed of the telescopic end of the telescopic rod 206. The excess air in the inner cavity of the telescopic rod 206 enters the airbag 601, and the air in the airbag 601 increases, causing the airbag 601 to expand. This can further prevent the telescopic end of the telescopic rod 206 from suddenly sliding rapidly, resulting in the over-fast movement of the injection pipe 207. When the protrusion on the surface of the solidified aluminum passes over the flexible plate 204, the airbag 601 contracts and sends the air inside it back to the inner cavity of the circular tube 202 through the telescopic rod 206, the hose, and the air delivery pipe 501. As the solidified aluminum gradually thickens, when the balloon 205 is about to completely contract, the electromagnet 401 can generate a suction force on the sliding tube 301, and the sliding tube 301 is affected and slides rapidly upward, thereby suddenly increasing the air in the inner cavity of the telescopic rod 206. At this time, through the damping strip and the airbag 601, the extension speed of the telescopic end of the telescopic rod 206 can be restricted again to prevent the telescopic end of the telescopic rod 206 from suddenly sliding rapidly. Thus, the position of the injection pipe 207 can be adaptively adjusted, increasing the falling time of the aluminum liquid in the air and improving the fragmentation and atomization effect of the aluminum liquid.,

[0026] Embodiment 2 As Figures 7 - 10 shown, it further includes a cleaning mechanism. The cleaning mechanism includes a trigger switch 701. The trigger switch 701 is fixedly installed in the bracket 201, and an electric push rod 702 is fixedly installed. The trigger switch 701 is electrically connected to the injection pipe 207 and the electric push rod 702. The telescopic end of the electric push rod 702 is fixedly connected to a collection box 703. A cylindrical groove is opened on one side of the collection box 703. A sliding shaft is slidably connected in the cylindrical groove. A compression spring is arranged between the sliding shaft and the inner wall of the cylindrical groove. One end of the sliding shaft is fixedly connected to a connecting frame 704. The bottom of the connecting frame 704 is slidably connected to a swing rod 7041. When the connecting frame 704 descends, the swing rod 7041 can be gradually lifted and slid obliquely upward. A through groove is opened at the top of the collection box 703. One end of the connecting frame 704 is slidably clamped into the through groove and is fixedly connected with a plurality of uniformly distributed crushing cones 705. The solidified aluminum can be crushed by the plurality of crushing cones 705.

[0027] As Figure 8 shown in Figure 9 shown, the cleaning mechanism further includes a toothed plate 706. The toothed plate 706 is fixedly connected to the bottom of the connecting frame 704. The crushing effect on the solidified aluminum can be further improved through the toothed plate 706.

[0028] As Figures 8 - 10As shown, it further includes a rotating wheel 801. A rotating wheel 801 is arranged on one side of the connecting frame 704. One end of the rotating wheel 801 is fixedly connected with a protruding shaft. One side of the connecting frame 704 is fixedly connected with a dial block 802 that cooperates with the protruding shaft. When the rotating wheel 801 rotates, it can drive the protruding shaft on it to squeeze the inclined surface of the dial block 802, causing several crushing cones 705 and the toothed plate 706 to move.

[0029] As Figure 8 with Figure 11 As shown, it further includes a crushing mechanism. The crushing mechanism includes a crushing pipe 901. One side of the collection box 703 is communicated with a crushing pipe 901. The rotating wheel 801 is rotatably connected to one end of the crushing pipe 901. A negative pressure fan is installed in the crushing pipe 901. The other end of the crushing pipe 901 is embedded and fixedly connected with a screen 902. One end of the rotating wheel 801 is fixedly connected with a stirring frame 903. Several steel balls are arranged in the crushing pipe 901. When the rotating wheel 801 rotates, it can make the stirring frame 903 rotate. The rotation of the stirring frame 903 can make several steel balls in the crushing pipe 901 move to crush the solidified aluminum.

[0030] As Figure 11 As shown, it further includes an elastic telescopic shaft 1001. One end of the crushing pipe 901 away from the rotating wheel 801 is fixedly connected with an elastic telescopic shaft 1001. The telescopic end of the elastic telescopic shaft 1001 is fixedly connected with a vertical shaft 1002. Two ejector rods are fixedly connected to the outer wall of the vertical shaft 1002. One end of the stirring frame 903 rotatably penetrates through the screen 902 and is fixedly connected with two top blocks 1003. Both top blocks 1003 cooperate with the vertical shaft 1002. When the stirring frame 903 rotates, it can make the two top blocks 1003 squeeze the outer wall of the vertical shaft 1002.

[0031] As the telescopic rod 206 continuously drives the injection pipe 207 to move through the sliding plate 503, when the balloon 205 is fully contracted, the sliding plate 503 contacts and presses the trigger switch 701. After being pressed, the trigger switch 701 activates the electric push rod 702 and closes the injection pipe 207, so that the injection pipe 207 no longer sprays molten aluminum. The telescopic end of the electric push rod 702 slowly extends and drives the collection box 703 to descend. The collection box 703 drives the connecting frame 704 to descend through the sliding shaft therein, and drives the rotating wheel 801 to descend through the crushing pipe 901. The connecting frame 704 drives the amplitude-changing rod 7041, several crushing cones 705 and the toothed plate 706 to descend. It should be noted that there is a gap between the inner circle of the solidified aluminum sprayed by the injection pipe 207 on the ultrasonic vibrating disk 101 and the landing point of the amplitude-changing rod 7041. After the amplitude-changing rod 7041 descends, it contacts the surface of the ultrasonic vibrating disk 101 where aluminum is not adhered. After several crushing cones 705 and the toothed plate 706 descend, they contact the solidified aluminum on the ultrasonic vibrating disk 101. At this time, the vibration force of the ultrasonic vibrating disk 101 is conducted to the amplitude-changing rod 7041. Since the amplitude-changing rod 7041 is inverted conical and stepped from bottom to top, the special shape of the amplitude-changing rod 7041 can amplify the amplitude of the ultrasonic vibrating disk 101, so that the amplitude generated by the crushing cones 705 and the toothed plate 706 increases. At this time, the ultrasonic vibrating disk 101 keeps rotating. Through vibration, the crushing cones 705 and the toothed plate 706 can crush the solidified aluminum on the surface of the ultrasonic vibrating disk 101.

[0032] At the same time, start the negative pressure fan inside the crushing pipe 901 to create a negative pressure inside the collection box 703. The crushed aluminum enters the crushing pipe 901 through the collection box 703 under the action of the negative pressure. At this time, the rotation of the ultrasonic vibrating disk 101 can apply a frictional force to the rotating wheel 801, thereby driving the rotating wheel 801 to rotate. The rotating wheel 801 drives the protruding shaft on it and the stirring frame 903 to rotate. When the protruding shaft rotates, it contacts and squeezes the inclined surface of the shifting block 802. The shifting block 802 is forced to drive the connecting frame 704 to move obliquely downward. The connecting frame 704 drives the sliding shaft to slide along the cylindrical groove of the collection box 703, and drives several crushing cones 705 and the toothed plate 706 to move. The compression spring is forced to contract. Subsequently, the protruding shaft passes over the shifting block 802 and no longer contacts it. After the shifting block 802 is released from the restriction, the connecting frame 704 can move. The compression spring is released and drives the connecting frame 704 to slide back to its original position through the sliding shaft. The connecting frame 704 drives several crushing cones 705 and the toothed plate 706 to return to their original positions. Then repeat the above steps to achieve the same effect. By making the connecting frame 704 reciprocate, the connecting frame 704 can drive the crushing cones 705 and the toothed plate 706 to reciprocate, increasing the contact area between several crushing cones 705 and the toothed plate 706 and the aluminum, and improving the peeling efficiency of the aluminum. When the stirring frame 903 rotates, it drives two top blocks 1003 to rotate, and drives several steel balls inside the crushing pipe 901 to move (the steel balls are prior art and not shown in the figure, so they will not be elaborated here). Several steel balls move upward along the inner wall of the crushing pipe 901 under the action of the stirring frame 903. When several steel balls move to a certain height, several steel balls quickly fall on the aluminum inside the crushing pipe 901 under the influence of their own weight, thereby applying a crushing effect to the aluminum again and crushing the aluminum into aluminum powder. When the aluminum powder reaches the appropriate particle size, the aluminum powder can be discharged through the mesh holes of the sieve 902. While the stirring frame 903 rotates, the stirring frame 903 drives two top blocks 1003 to rotate. The inclined surfaces of the two top blocks 1003 squeeze the outer wall of the vertical shaft 1002. The vertical shaft 1002 is forced to drive two ejector rods to move away from the sieve 902, and drives the telescopic end of the elastic telescopic shaft 1001 to extend until the ends of the two top blocks 1003 away from the sieve 902 pass over the vertical shaft 1002. The telescopic end of the elastic telescopic shaft 1001 quickly contracts and returns to its original position, and drives two ejector rods to quickly return to their original positions through the vertical shaft 1002. After the two top blocks 1003 return to their original positions, they hit the sieve 902, causing the sieve 902 to vibrate and discharging the aluminum powder blocked in the mesh holes of the sieve 902. Thus, the solidified aluminum on the ultrasonic vibrating disk 101 can be recycled and crushed. As the telescopic end of the electric push rod 702 gradually extends, the horn 7041, several crushing cones 705 and the toothed plate 706 slowly descend. It should be noted that the top surface of the ultrasonic vibrating disk 101 is conical. During the slow descent of the horn 7041, the horn 7041 is squeezed by the surface of the ultrasonic vibrating disk 101 and gradually slides obliquely upward along the connecting frame 704. During the sliding of the horn 7041,The horn 7041 always adheres to the surface of the ultrasonic vibrating disk 101, so that the amplified amplitude of the horn 7041 can be maintained at a stable value. Furthermore, the crushing effect of several crushing cones 705 and the toothed plate 706 on the solidified aluminum can be kept stable until the telescopic end of the electric push rod 702 fully extends, then the negative pressure fan is turned off, and then the telescopic end of the electric push rod 702 is controlled to contract and reset. As a result, the horn 7041, several crushing cones 705 and the toothed plate 706 are reset, and the rotating wheel 801 is reset. Thus, the complete recovery and crushing of the aluminum on the surface of the ultrasonic vibrating disk 101 are completed. At this time, the flexible plate 204 is no longer squeezed and rotates and resets under the influence of its own weight. The balloon 205 is no longer squeezed. The electromagnet 401 is turned off, and the electromagnet 401 no longer adsorbs the sliding tube 301. After the sliding tube 301 is released from the restriction, it can move. The injection tube 207 and the sliding plate 503 are affected by their own weights, so that the sliding plate 503 drives the injection tube 207 to slide and reset along the guide rail 502. The telescopic end of the telescopic rod 206 is reset, and the air in the cavity of the telescopic rod 206 returns to the circular tube 202 through the hose and the air delivery pipe 501, and pushes the sliding tube 301 to reset. Thus, the overall device is reset.,
