Description

TECHNICAL FIELD

[0001] The utility model relates to powder metallurgy equipment technical field especially, relates to a kind of gas atomization powdering equipment with powder collection system. BACKGROUND

[0002] The target material is the sputtering source in magnetron sputtering, and the target material used in the preparation of thin-film solar cell chips is usually prepared by spraying alloy powder on the target backing tube. The alloy powder used in the target material is generally prepared by gas atomization powdering process. In the prior art, after powdering by the gas atomization powdering equipment, the powder prepared by the gas atomization powdering equipment needs to be collected. During the collection, the atomized powder first falls vertically from the discharge port of the atomization chamber, then enters the conical hopper, and finally falls into the collection hopper. However, during the vertical falling process of the atomized powder from the discharge port of the atomization chamber, part of the powder will remain and adhere to the inner side wall of the conical hopper. This causes the powder adhering to the inner side wall of the conical hopper to have increased iron content and cannot be collected as qualified products, resulting in reduced yield of the atomized powdering. Moreover, the powder remaining on the inner side wall of the conical hopper is not easy to clean, and the conical hopper needs to be disassembled and cleaned after the atomization is completed, which increases the labor and time cost of the atomized powdering. SUMMARY

[0003] The utility model aims at solving the problems in the background art and provides a kind of gas atomization powdering equipment with powder collection system.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A kind of gas atomization powdering equipment with powder collection system, including atomization bin, conical hopper and collection bin, the bottom of the atomization bin is fixed with conical hopper, the bottom of the conical hopper is fixed with collection bin, the inside of the collection bin is embedded with collection hopper, the lower left of the outer wall of the atomization bin is fixed with fan, the lower right of the outer wall of the atomization bin is fixed with servo motor, the transmission shaft bottom of the power output end of the servo motor is rotatably connected with gear disc, the inside of the atomization bin is embedded with rotary disc, the inside of the atomization bin is fixed with limit ring by support, the inner wall of the rotary disc is fixed with cleaning plate.

[0006] Preferably, the teeth of the outer wall of the gear disc are engaged with the teeth of the outer wall of the rotary disc, and the rotary disc rotates horizontally in the atomization bin.

[0007] Preferably, the outer wall of the cleaning plate closely adheres to the inner wall of the conical hopper and the collection bin, and the cleaning plate is arranged in a circular ring around the middle part of the rotary disc.

[0008] Preferably, the internal opening of the rotating disc is provided with a connecting groove, the limiting ring is embedded on the inside of the connecting groove, and the cross-sectional area of the connecting groove is consistent with the cross-sectional area of the limiting ring.

[0009] Preferably, the exhaust end of the fan is communicated with the inside of the connecting groove through a pipeline, and the limiting ring rotates horizontally above the inside of the rotating disc.

[0010] Preferably, the hollow channel in the cleaning plate is communicated with the inside of the connecting groove, and the outer wall of the cleaning plate is provided with an exhaust hole communicated with the hollow channel.

[0011] When powder is adhered to the inner wall of the conical hopper and the collection bin, the servo motor drives the rotating disc to rotate through the gear disc, so that the rotating disc drives the cleaning plate to rotate in the inner wall of the conical hopper and the collection bin. Since the outer wall of the cleaning plate is tightly attached to the inner wall of the conical hopper and the collection bin, the cleaning plate can scrape off the adhered powder in the inner wall of the conical hopper and the collection bin during rotation. While the rotating disc drives the cleaning plate to rotate, the fan generates airflow which enters the connecting groove in the inside of the rotating disc through the pipeline. Then, the airflow enters the hollow channel of the cleaning plate due to the effect of air pressure, and is discharged from the exhaust hole in the outer wall of the cleaning plate, blowing towards the inner wall of the conical hopper and the collection bin, so that the adhered powder in the inner wall of the conical hopper and the collection bin falls quickly. The working efficiency is higher, the powder collection effect is better, and the use is more convenient. BRIEF DESCRIPTION OF DRAWINGS

[0019] The gear of gear disc 501 outer wall is engaged with the gear of rotary disc 6 outer wall, and rotary disc 6 rotates horizontally in atomizing bin 1.

[0020] The outer wall of cleaning plate 602 is close to the inner wall of conical hopper 2 and collection bin 3, and the cleaning plate 602 is arranged in a circular ring around the middle part of rotary disc 6.

[0021] When powder sticks to the inner wall of conical hopper 2 and collection bin 3, servo motor 5 drives rotary disc 6 to rotate through gear disc 501, so that rotary disc 6 drives cleaning plate 602 to rotate on the inner wall of conical hopper 2 and collection bin 3. Since the outer wall of cleaning plate 602 is close to the inner wall of conical hopper 2 and collection bin 3, the powder sticking to the inner wall of conical hopper 2 and collection bin 3 can be scraped off in the rotating process of cleaning plate 602.

[0022] In example 2, the difference between example 2 and example 1 is that, in the present embodiment, the inside hole of rotary disc 6 is provided with a connecting groove, and the limit ring 601 is embedded in the upper part of the inside hole of the connecting groove, and the cross-sectional area of the connecting groove is consistent with the cross-sectional area of the limit ring 601.

[0023] Since the limit ring 601 is embedded in the connecting groove in the upper part of the inside hole of rotary disc 6, when rotary disc 6 rotates, rotary disc 6 will rotate on the outer wall of limit ring 601, and limit ring 601 will seal the upper part of the connecting groove at this time. Therefore, when the airflow generated by fan 4 enters the connecting groove in the upper part of the inside hole of rotary disc 6, the airflow can normally enter the hollow channel in the inside of cleaning plate 602 without being discharged from the upper part of the connecting groove.

[0024] The exhaust end of fan 4 is communicated with the inside of the connecting groove through a pipeline, and the limit ring 601 rotates horizontally in the upper part of the inside hole of rotary disc 6.
