A blanking port is opened on the melting tank 1 on one side of the conical sieve plate 21 and is communicated with the feeding box 11. Open the sealing cover plate 12, add alloy micro-powder into the feeding box 11, start the screw elevator 14, and the screw elevator 14 transports the alloy micro-powder into the melting tank 1. The alloy micro-powder falls from the upper part of the melting tank 1 onto the auxiliary blanking plate 23, and the alloy micro-powder is guided by the auxiliary blanking plate 23 to fall onto the electric crushing and grinding roller 24. Start the electric crushing and grinding roller 24 to crush and grind the alloy micro-powder. After that, the alloy micro-powder falls into the guiding funnel 22, and is guided by the guiding funnel 22, and the alloy micro-powder falls from the middle of the guiding funnel 22 onto the conical sieve plate 21. Start the servo motor 17, and the output shaft of the servo motor 17 rotates to drive the transmission shaft column 18 to rotate. The transmission shaft column 18 rotates to drive the conical sieve plate 21 to rotate. The rotating conical sieve plate 21 screens the alloy micro-powder, and the alloy micro-powder with larger particle size falls back into the feeding box 11, and the process of crushing and grinding is repeated.

[0023] A conical tank bottom 15 is arranged at the bottom end of the inner side wall of the melting tank 1. The side end of the melting tank 1 is fixedly installed with a discharge pipe 16.

After that, open the discharge pipe 16 to discharge the finished product from the melting tank 1.

[0024] Working principle:

[0025] First step, when the alloy micro-powder melting and sintering device is in use, open the sealing cover plate 12, add the alloy micro-powder into the feeding box 11, start the screw elevator 14, and the screw elevator 14 transports the alloy micro-powder to the melting tank 1. The alloy micro-powder falls from above the melting tank 1 onto the auxiliary blanking plate 23, and is guided by the auxiliary blanking plate 23 to fall onto the electric crushing and grinding roller 24. Start the electric crushing and grinding roller 24 to crush and grind the alloy micro-powder. Then the alloy micro-powder falls into the guiding funnel 22, and is guided by the guiding funnel 22 to fall from the middle of the guiding funnel 22 onto the conical sieve plate 21. Start the servo motor 17, and the output shaft of the servo motor 17 rotates to drive the transmission shaft column 18 to rotate. The transmission shaft column 18 rotates to drive the conical sieve plate 21 to rotate. The rotating conical sieve plate 21 screens the alloy micro-powder. The alloy micro-powder with larger particle size falls back into the feeding box 11, and the process of crushing and grinding is repeated. By designing and installing the screw elevator 14, conical sieve plate 21 and electric crushing and grinding roller 24 in the alloy micro-powder melting and sintering device, during the alloy micro-powder melting and sintering process, the screw elevator 14, conical sieve plate 21 and electric crushing and grinding roller 24 cooperate to pre-treat the alloy micro-powder raw material, making the particle size distribution of the alloy micro-powder raw material more uniform, thereby improving the uniformity of melting and sintering and the performance of the final product.

[0026] Second step, when the alloy micro-powder melting and sintering device is in use, the alloy micro-powder is transported from the feeding box 11 to the melting tank 1 via the screw elevator 14, and then is crushed and screened by the cooperation of the electric crushing and grinding roller 24 and the conical sieve plate 21, so that the alloy micro-powder with relatively uniform particle size falls from the conical sieve plate 21 onto the conical tank bottom 15. Start the heating mechanism 2 to heat the alloy micro-powder in the melting tank 1 to the molten state and sinter it. Start the servo motor 17, and the output shaft of the servo motor 17 rotates to drive the transmission shaft column 18 to rotate. The transmission shaft column 18 rotates to drive the stirring blade 19 to rotate. The rotating stirring blade 19 stirs the alloy micro-powder. Then open the discharge pipe 16 to discharge the finished product from the melting tank 1. By installing the stirring blade 19 in the alloy micro-powder melting and sintering device, during the alloy micro-powder melting and sintering process, the rotating stirring blade 19 stirs the alloy micro-powder, making the alloy micro-powder raw material heat more evenly, and thus effectively improving the efficiency of the melting work.
