[0036] The functions of the horizontal base 22 include: keeping the support frame 21 and the silo 11 in a horizontal state, and cooperating with auxiliary equipment to move the powder collecting device. In the middle of the horizontal base 22, a hollow hole is set at a position opposite to the discharge valve, and the hollow hole can smoothly pass through other equipment (such as a small running barrel), thereby completing the operation of the metal powder.

[0037] When the powder collecting device needs to be moved, the upper valve body 12 is closed, and the powder collecting device is quickly withdrawn from the material receiving position, and a new powder collecting device is replaced, and the upper valve body 12 of the new powder collecting device (empty) is connected to the metal powder manufacturing equipment. In the process of replacing the powder collecting device, the connection of the upper valve body 12 can be quickly disassembled and assembled, and the metal powder manufacturing equipment can continue to operate without stopping the machine.

The forklift can complete the insertion operation on all four sides of the horizontal placement surface 222, and the fork arm of the forklift is inserted into the strip groove 2221, thereby realizing a stable connection between the horizontal placement surface 222 and the forklift.

[0043] In the embodiment of the utility model, the metal powder in the powder making equipment (metal powder manufacturing equipment) enters into the silo 11, and the metal powder in the silo 11 enters into the transfer equipment, all of which are carried out under a negative pressure environment. Auxiliary pressure detection and adjustment equipment can be set on the silo 11, and when the space changes in the silo 11, the stability in the silo 11 can be maintained by introducing inert gas to prevent the metal powder from contacting with the air, that is, to prevent the metal powder from contacting with the air and being oxidized.

[0047] For example, a sealing ring is provided at the edge of the cleaning port 112 and / or the edge of the upper cover 113, and the sealing ring can be used to seal the two when they are installed. By setting the upper cover 113 in a detachable form, it is convenient to clean the inside of the silo 11 when replacing the metal powder material.

[0048] like Figure 4 As shown, the embodiment of the utility model further provides a powder making device, including the above-mentioned powder collecting device. For example, the powder making device is an electrode induction melting gas atomization powder making device.

The powder making equipment continuously produces metal powder and drops it into the silo 11. The silo 11 has a certain capacity and can accommodate a certain volume of metal powder. When the powder collecting device is not moved, the lower valve body 13 can be opened, and the metal powder can be transported using a small transfer barrel. When the powder collecting device needs to be moved, the upper valve body 12 and the powder making equipment are quickly disconnected, and the empty powder collecting device is replaced. The upper valve body 12 can be used to quickly disassemble and assemble, so there is no need to shut down the powder making equipment. The technical solution of the utility model can realize the continuous collection of metal powder.
