The particle shape of the metal powder is one of the main factors affecting the powder performance, and the common particle shapes include spherical, nearly spherical, flaky, acicular and other irregular shapes. The high-sphericity powder particles have good fluidity, and the powder feeding and spreading are uniform, so that the density and uniformity of a finished piece are favorably improved, and therefore, the metal powder particles for surface protection are generally required to be spherical or nearly spherical. The metal powder is usually prepared by an atomization method, and the surface of the prepared powder is influenced by factors such as static electricity or micro metallurgy, so that part of fine powder is adsorbed, the sphericity of the powder is influenced, and the flowability of the powder is poor. Therefore, before the metal powder is used, the powder needs to be treated to remove the fine powder and improve the powder performance.

The staff rotates the angle of installation pipe 7 to make two rolling assemblies set up along the direction of height on the installation pipe 7, then the staff passes first stay cord 73, second stay cord 74 respectively and handles the through-hole on jar 1, and the winding is on the winding wheel that corresponds, and wherein first stay cord 73 still needs to pass two spacing rings 791 at scale 79 both ends. Thereby completing the installation of the gas lance 211 and the conditioning assembly on the process tank 1.

When the worker needs to adjust the air injection angle of the air injection pipe 211, the worker can adjust the identification band 731 to the corresponding position of the scale 79 by rotating the grooved pulley 77 above the installation pipe 7, and then tighten the second pull rope 74, thereby completing the adjustment.

Example 3:

the present embodiment is different from embodiment 2 in that: a feed inlet 1211 at the upper end of the treatment tank 1 and a discharge outlet below the treatment tank 1.

As shown in fig. 7, a feeding pipe 16 is disposed above the processing tank 1 in this embodiment, the feeding pipe 16 is communicated with the feeding port 1211, a raw material bin (not shown in the figure) is connected to the upper end of the feeding pipe 16, an electromagnetic flow meter 161 is further disposed on the feeding pipe 16, when feeding work is required, a worker can control the electromagnetic flow meter 161 to open, metal powder in the raw material bin falls into the processing tank 1, and when the metal powder in the processing tank 1 reaches a preset value, the electromagnetic flow meter 161 is closed, and the raw material bin stops feeding into the processing tank 1. Then the fine powder separation mechanism 2 and the fine powder recovery mechanism 3 work to separate the fine powder from the metal powder.

The arrangement of the feeding pipe 16, the raw material bin and the electromagnetic flow meter 161 enables the fine powder processing tank 1 to realize automatic blanking, thereby improving the convenience and the continuity of fine powder processing work. On the other hand, the processing tank 1 is sealed with the raw material bin, so that the mixing of impurities is reduced, and the product quality is improved.

A vacuum box 17 is further arranged below the treatment tank 1, the upper end of the vacuum box 17 is communicated with the discharge port, butterfly valves 171 for controlling the vacuum box 17 to be opened and closed are further arranged at the upper end and the lower end of the vacuum box 17 respectively, a vacuum pump (not shown in the figure) for maintaining the vacuum environment inside the vacuum box 17 is connected into the vacuum box 17, and a filtering component for blocking metal powder is arranged at the joint of the vacuum box 17 and the vacuum pump.

After the treatment tank 1 finishes treating the metal powder, the worker can open the butterfly valve 171 above the vacuum box 17, the metal powder enters the vacuum box 17 for temporary storage, then the worker closes the butterfly valve 171 above the vacuum box 17 and opens the butterfly valve 171 below the vacuum box 17, and therefore the metal powder is discharged. The setting of vacuum box 17 makes vacuum box 17 when carrying out the blowing on the one hand, and processing jar 1 can normally work to improve work efficiency, on the other hand vacuum box 17's setting has still reduced external impurity and has got into processing jar 1, thereby has improved the stability and the processing quality of processing jar 1 work.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
