Description

Technical Field

[0001] The invention belongs to the technical field of tin powder atomization, and specifically relates to an automatic tin powder atomization machine. Background Art

[0002] The tin powder automatic atomizer is a device specially designed to convert tin materials into fine particles (i.e. tin powder). It disperses molten or liquid tin into tiny droplets through specific atomization techniques, such as gas injection, mechanical centrifugation or ultrasonic vibration. These droplets are then rapidly cooled and solidified into tin powder in the air. The tin powder automatic atomizer is widely used in many fields, such as electronics, chemical industry, metallurgy, etc. In the electronics industry, tin powder is used to manufacture electronic components, circuit boards, etc.; in the chemical industry, tin powder can be used as a catalyst or additive; in the metallurgical industry, tin powder is used in alloy preparation, metal coating, etc.

[0003] The prior art also proposes some solutions: for example, a Chinese patent with announcement number CN212526059U discloses a tin powder atomization device, in which a cold air inlet connected to an atomization chamber is provided on an atomization barrel, a feed port is provided on the upper end of the atomization barrel, a lower barrel is detachably connected to the feed port, at least a portion of the lower end of the lower barrel extends into the atomization chamber, and a tin solution in a droplet state is contacted with low-temperature nitrogen to condense the tin solution in a droplet state into tin powder. The tin powder falls to the bottom and flows out from the tin powder outlet, thereby making the processing of the tin powder simpler.

[0004] When the existing tin powder atomization device is in use, the solution is thrown out by the turntable and mixed with the nitrogen in the atomization box to quickly cool to form tin powder. The size of the droplets thrown out by the turntable may be uneven, and it is difficult to accurately control the particle size of the final tin powder. In addition, the solution thrown out by the turntable is usually concentrated in specific areas. The nitrogen in these areas will be quickly consumed, resulting in excessive reaction of the solution in these areas and insufficient reaction of the solutions in other areas. The tin powder will contain impurities or uneven particle size due to insufficient reaction. In addition, other nitrogen in the atomization box may not be effectively utilized, resulting in waste of nitrogen.

[0023] 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 explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 10As shown, the present invention provides a technical solution: an automatic tin powder atomizer, comprising an atomizing box 1, a box cover 2 is fixedly connected to the top of the atomizing box 1, a liquid distributor 3 is arranged inside the atomizing box 1, a plurality of nozzles 6 are arranged on the outside of the liquid distributor 3, a connecting pipe 11 is fixedly connected to one side of the liquid distributor 3, an end of the connecting pipe 11 away from the liquid distributor 3 is fixedly connected to a liquid storage tank 39, a one-way valve 12 is fixedly installed on the outer wall of the connecting pipe 11, a liquid pumping component is arranged above the liquid distributor 3, the liquid pumping component is used to suck the tin solution in the liquid storage tank 39 into the interior of the liquid distributor 3, a swinging component is arranged on the top of the external hose 4, the swinging component is used to drive the plurality of nozzles 6 to swing, and an internal stirring component for stirring the tin solution is arranged inside the liquid distributor 3.

[0025] During operation: initially, the tin solution is added to the interior of the liquid storage tank 39, and the solution is pumped into the interior of the liquid distributor 3 through the liquid pumping component. When there is enough solution in the liquid distributor 3, the entire liquid pumping process is closed. At this time, the internal nitrogen of the atomizing box 1 is added to a saturated state, and the solution is discharged through the liquid pumping component. Due to the one-way valve 12 provided, the solution will not flow back to the interior of the liquid storage tank 39 when discharged, but will be quickly sprayed out through the nozzles of each nozzle 6. The solution can form fine droplets when sprayed, and will react with the nitrogen inside the atomizing box 1 to form tin powder, completing the atomization forming process of the tin powder. In the process of the liquid pumping component discharging the solution, the swing component will drive multiple nozzles 6 to swing, and the nozzle 6 will spray the solution and cooperate with the process of swinging up and down, so that the solution can react evenly with the nitrogen in various areas and corners inside the atomizing box 1 when sprayed. It helps to distribute the solution more evenly in the atomization box, ensuring that the solution in each area can fully contact and react with the nitrogen. In addition, when the liquid extraction component is extracting and discharging liquid, the internal stirring component is always in motion, and the solution drawn into the liquid separator 3 can be stirred during the movement. The concentration of the solution after stirring is more uniform, and the tin solution after stirring can form more delicate and uniform droplets when sprayed, thereby improving the quality of the tin powder. Through the above embodiment, the tin solution is sprayed through the nozzle 6 through the liquid extraction component. Compared with the method of centrifugally throwing out the tin solution with a turntable, the obtained tin powder has a more regular shape and better sphericity, thereby obtaining a higher purity tin powder. When the solution is sprayed through the nozzle 6, the swinging component is used to make the solution more evenly distributed in the atomization box, thereby improving the reaction efficiency with nitrogen. Under the action of the internal stirring component, the solution can be mixed evenly before spraying, further improving the quality of the produced tin powder.

[0026] like Figures 4 to 5As shown, the liquid extraction component includes a communicating vessel 8, a cover plate 7 is fixedly connected to the top of the liquid distributor 3, the top of the cover plate 7 is fixedly connected to the bottom of the communicating vessel 8, a piston head 9 is arranged inside the communicating vessel 8, the maximum outer diameter of the piston head 9 is the same as the inner diameter of the communicating vessel 8, a lifting rod 10 is fixedly connected to the top of the piston head 9, a support frame 14 is fixedly installed on the top of the box cover 2, a telescopic cylinder 15 is fixedly installed on the bottom side of the support frame 14, and the output end of the telescopic cylinder 15 is fixedly connected to the top of the lifting rod 10.

[0027] During operation: initially, the piston head 9 is located at the bottom of the inner wall of the communicating vessel 8. When the liquid is extracted by the liquid extraction component, the telescopic cylinder 15 is started, and its output end will drive the piston head 9 to slide upward in the inner wall of the communicating vessel 8 through the lifting connecting rod 10. Since the nozzles of multiple nozzles 6 are blocked at this time, the piston head 9 will draw the tin solution inside the liquid storage tank 39 into the interior of the liquid distributor 3 through the connecting pipe 11 when sliding upward. Similarly, when the solution is discharged through the liquid extraction component, the piston head 9 slides downward on the inner wall of the communicating vessel 8 through the telescopic cylinder 15. At this time, the nozzles of multiple nozzles 6 will not be blocked, and the solution will not flow back due to the setting of the one-way valve 12. Therefore, the solution will be evenly sprayed out through the nozzles of multiple nozzles 6. Therefore, after the solution reacts with the nitrogen inside the atomization box 1, the shape of the tin powder will be more regular and the sphericity will be better.

[0028] like Figure 5 to Figure 6 As shown, one end of multiple nozzles 6 is fixedly connected to an external hard tube 5, one end of multiple external hard tubes 5 away from the nozzle 6 is fixedly connected to an external hose 4, one end of multiple external hoses 4 away from the external hard tube 5 is movably connected to the outer wall of the dispenser 3, an extrusion spring 23 is arranged on the outside of the external hose 4, one end of the extrusion spring 23 is fixedly connected to one side of the external hard tube 5, and the other end of the extrusion spring 23 is fixedly connected to the outer wall of the dispenser 3, and a shielding component is arranged at the nozzle of the nozzle 6.

[0029] During operation: initially, the nozzles of multiple nozzles 6 face downward. At this time, when the liquid extraction component drives the piston head 9 to move upward, the external hard tube 5 will be driven to move upward through the swing component. When the external hard tube 5 moves upward, it will rotate with the intersection of the external hose 4 and the liquid distributor 3 as the axis, and will squeeze or stretch the extrusion spring 23 and the external hose 4 during the rotation, thereby achieving the effect that the external hard tube 5 drives the nozzle 6 to shake upward when it rises, and when the nozzle 6 shakes upward, its nozzle is always blocked by the action of the shielding component, and the nitrogen inside the atomization box 1 will not be drawn into the liquid distributor 3. When the piston head 9 descends to discharge liquid, multiple nozzles 6 shake downward. At this time, the nozzle will not be blocked, and the solution inside the liquid distributor 3 will be sprayed out from the nozzles of each nozzle 6.

[0030] like Figure 6 to Figure 7As shown, the swing assembly includes a segmented connector 16, which is fixedly installed on the outer wall of the lifting rod 10, and a plurality of connecting rods 17 are fixedly connected to the bottom of the segmented connector 16, and a hinge 19 is fixedly connected to the bottom of the connecting rod 17, and a hinge rod 18 is fixedly connected to the top of the external hard tube 5, and one end of the hinge rod 18 is hinged to the shaft rod of the hinge 19, and the outer wall of the external hard tube 5 is symmetrically fixedly connected to a hinge rod 20, and the outer wall of the hinge rod 20 is hinged with a double-end hinge rod 21, and the double-end hinge rod 21 is hinged with a hinge 22 at one end away from the hinge rod 20, and the hinge 22 is fixedly installed on the outer wall of the dispenser 3.

[0031] During operation: when the lifting connecting rod 10 drives the piston head 9 to rise to pump liquid, it will also drive multiple hinged parts 19 to move upward through the segmented connecting parts 16 and multiple connecting rods 17. The hinged part 19 will drive the external hard tube 5 to move upward through the hinged rod 18. When the external hard tube 5 moves upward, the nozzle of the nozzle 6 can be lifted upward, and the double-end hinged rod 21 and the hinged part 22 can be hinged and rotated. Since the nozzle 6 and the external hard tube 5 are supported by the intersection of the external hose 4 and the liquid distributor 3, the nozzle 6 will be lifted upward in an arc shape. Similarly, when the nozzle 6 descends, its nozzle can face different directions inside the atomizing box 1 when discharging liquid, so that the solution can be evenly mixed with the nitrogen in various areas inside the atomizing box 1, thereby improving the reaction efficiency of the solution and the nitrogen.

[0032] like Figures 8 to 9 As shown, the shielding assembly includes a plurality of arc-shaped baffles 24, the upper half of which is arc-shaped, the inner side of the arc-shaped baffles 24 fits against the nozzle of the nozzle 6, a connecting plate 25 is fixedly connected between the bottoms of the plurality of arc-shaped baffles 24, a cover plate 213 is fixedly connected to the bottom of the dispenser 3, an electric rotating rod 26 is rotatably connected to the center point of the cover plate 213, and the electric rotating rod 26 is fixedly connected to the connecting plate 25.

[0033] During operation: During the liquid extraction process, the nozzle of the nozzle 6 faces downward, and the inner side of the arc-shaped plugging plate 24 fits with its nozzle. Since the upper part of the arc-shaped plugging plate 24 is arc-shaped, when the nozzle 6 is lifted and shaken upward, the nozzle is always in contact with the arc-shaped plugging plate 24. Therefore, when extracting liquid, the nitrogen inside the atomizing box 1 will not enter the liquid distributor 3, while the solution inside the liquid storage tank 39 can enter the liquid distributor 3. When discharging liquid, the nozzle of the nozzle 6 faces upward, and the electric rotating rod 26 is controlled to rotate. The electric rotating rod 26 will drive multiple arc-shaped plugging plates 24 to rotate through the connecting disk 25, and the inner side thereof will not fit with the nozzle of the nozzle 6. When the nozzle 6 is shaken downward to discharge liquid, the solution can be sprayed from the nozzle to various areas inside the atomizing box 1.

[0034] like Fig. 9As shown, a plurality of limiting rods 27 are fixedly connected to the bottom of the connecting plate 25, and a plurality of limiting grooves 28 are provided on the inner wall of the surface of the second cover plate 13. The limiting rods 27 and the limiting grooves 28 are slidably connected and adapted to each other.

[0035] During operation: through the limiting rod 27 and the limiting groove 28, while improving the rotation stability of the arc blocking plate 24, the rotation range of the arc blocking plate 24 is also limited to avoid the arc blocking plate 24 from rotating too much. After the arc blocking plate 24 is rotated, it will still block the nozzles of other nozzles 6.

[0036] like Fig.10 As shown, the internal stirring assembly includes a plurality of stirring shafts 29, both ends of which are rotatably connected to the cover plate 1 7 and the cover plate 2 13 respectively, the outer walls of the plurality of stirring shafts 29 are fixedly connected with stirring blades 30, the stirring shafts 29 and the stirring blades 30 are both made of high temperature resistant materials, and a driving assembly for driving the plurality of stirring shafts 29 to rotate is arranged above the cover plate 1 7.

[0037] During operation: During the process of the liquid extraction and discharge by the liquid extraction component, the driving component will drive the multiple stirring shafts 29 to rotate, and the multiple stirring shafts 29 will drive the stirring blades 30 to rotate. When the solution exists inside the liquid separator 3, the stirring shafts 29 can stir the solution to achieve sufficient mixing, thereby further improving the quality of the produced tin powder.

[0038] like Fig.10 As shown, the driving assembly includes a plurality of gears 31, and the plurality of gears 31 are respectively fixedly connected to the top of the stirring shaft 29, the outer wall of the gear 31 is meshed with an inner toothed disc 32, the bottom of the inner toothed disc 32 is fixedly connected with an electric slider 33, and a circular slide groove 34 is provided on the inner wall of the top surface of the cover plate 7, and the electric slider 33 is slidably connected and matched with the circular slide groove 34.

[0039] During operation: the electric slider 33 is controlled to slide along the inner wall of the circular slide groove 34. During the sliding process, the inner tooth disc 32 can be driven to rotate. During the rotation process, the inner tooth disc 32 can simultaneously drive multiple gears 31 to rotate, thereby achieving the effect of driving multiple gears 31 to rotate and achieving the effect of stirring the solution.

[0040] like Figures 2 to 3 As shown, a powder collecting plate 35 is fixedly connected to the bottom of the atomizing box 1 , a powder outlet pipe 36 is fixedly connected to the bottom of the powder collecting plate 35 , and an electric valve 37 is fixedly installed on the outer wall of the powder outlet pipe 36 .

[0041] During operation: when the tin solution reacts with nitrogen to form tin powder, the electric valve 37 blocks the powder outlet pipe 36 to prevent the loss of nitrogen inside the atomization box 1. The produced tin powder will first fall onto the surface of the powder collecting plate 35. After the entire atomization work is completed, the electric valve 37 is opened, and the tin powder is discharged from the powder outlet pipe 36 to complete the collection of the tin powder.

[0042] like Figure 1 As shown, a plurality of mounting brackets 38 are fixedly connected to the outer wall of the atomizing box 1 , and the top of one of the mounting brackets 38 is fixedly connected to the bottom of the liquid storage box 39 .

[0043] During operation: the mounting frame 38 improves the stability of the entire atomizer during operation, and also facilitates the placement of the liquid storage tank 39.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
