DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] See also Figure 1 - Figure 5 In this embodiment, a metal powder transfer tank is involved, which is specifically used for closed storage and transit transportation of powders, effectively avoiding dust pollution and ensuring safe and moisture-free storage of powders. It specifically includes: a tank body 1 and a round tube support leg 2, a feed inlet 111 is provided on the top of the tank body 1, a discharge port 131 is provided on the bottom of the tank body 1, and the discharge port 131 is adapted to be equipped with a discharge valve 14, the round tube support leg 2 adopts a hollow structure, which is provided with an air inlet joint 21 connected to the cavity, and a nozzle 3 is provided in the tank body 1 that is unidirectionally connected to the cavity of the round tube support leg 2.

[0025] Specifically, in the present embodiment, the metal powder is usually prepared by a physical method (such as atomization and mechanical crushing) or a chemical method (such as reduction, electrolysis and carbonyl method). Before using the metal powder transfer tank, the operator first ensures that the transfer tank is clean and checks that the tank body 1 and the round tube support leg 2 are structurally intact. After the inspection, ensure that the discharge valve 14 is in a closed state, and then load the prepared metal powder into the tank body 1 through the feed port 111. After the transfer is completed, open the discharge valve 14 and discharge the metal powder through the discharge port 131. In particular, during the metal powder discharge stage, since the metal powder is under pressure during storage, a small amount of metal powder will adhere to the inner wall of the tank body 1. At this time, the air inlet connector 21 needs to be connected to the high-pressure gas source, and the high-pressure gas is finally ejected from the nozzle 3 in the tank body 1 through the cavity of the round tube support leg 2, and the residual metal powder is blown off from the inner wall of the tank body 1. The discharge valve 14 in this embodiment adopts a spherical valve to ensure that the tank body 1 does not leak under a vacuum state. The gas passed through the air inlet joint 21 should be an inert gas to prevent oxidation of the metal powder.

[0026] The circular tube support 2 comprises four vertical circular tubes 22 and three horizontal circular tubes 23. The horizontal circular tube 23 is installed between two vertical circular tubes 22. Both the vertical circular tube 22 and the horizontal circular tube 23 are hollow structures and the cavities between the circular tubes are interconnected. The upper end of the vertical circular tube 22 is provided with a one-way valve 24 that is unidirectionally connected to the tank body 1. One end of the one-way valve 24 is connected to the nozzle 3. The lower end surface of the vertical circular tube 22 is sealed. The outer side of any horizontal circular tube 23 is provided with an air inlet connector 21 that is connected to the cavity of the circular tube support 2. The circular tube support 2 in this embodiment not only provides a stable support for the tank body 1, but also serves as a channel for gas circulation, which helps to achieve pressure balance inside the tank body 1. The one-way valve 24 is used so that the gas can only flow from the circular tube support 2 to the tank body 1 through the nozzle 3, which can realize pressurized storage of metal powder and avoid oxidation of metal powder caused by external air entering the tank body 1 due to leakage of the tank body 1.

[0027] See also Figure 4 The nozzle 3 is adapted to be equipped with a baffle 31, and the baffle 31 is adapted to be equipped with a reset component 32. In this embodiment, a torsion spring is used as the reset component 32. The baffle 31 is hinged to one end of the nozzle 3 at which gas is discharged, and is reset elastically by the torsion spring, so that the baffle 31 fits with the nozzle 3 to achieve blocking of the nozzle 3. The specific working principle is as follows: when there is no high-pressure gas ejected, the torsion spring keeps the baffle 31 close to the nozzle 3 to prevent metal powder from entering the interior of the nozzle 3 and polluting the nozzle 3; when high-pressure gas is ejected through the nozzle 3, the force of the airflow overcomes the elastic force of the torsion spring to push the baffle 31 open, thereby allowing the gas to flow out.

[0028] See also Figure 5 The lower end of the vertical circular tube 22 is connected with a moving wheel 4, which is divided into two universal wheels 42 arranged at the lower end of the two vertical circular tubes 22 on the front side and two directional wheels 41 arranged at the lower end of the two vertical circular tubes 22 on the rear side. The two universal wheels 42 are adapted with brakes 43. The moving wheel 4 of this embodiment is made of polyurethane (PU) material, which will not cause wear on the self-leveling floor, has light load, low moving noise, and is light and flexible. The metal powder transfer tank can be easily moved to the designated position, and the universal wheel 42 can be locked by the brake 43 to ensure safety and transfer efficiency during operation.

[0029] A pad 25 is provided at the lower end of the vertical circular tube 22. The four corners of the pad 25 are rounded and smooth, and four oblong holes 251 are provided. The oblong holes 251 are connected to the moving wheel 4 through bolts and fastened by nuts. The rounded corners of the pad 25 in this embodiment reduce the possibility of accidental scratches during operation and increase the safety of use. The oblong holes 251 have a certain adjustment space, so that the installation position of the moving wheel 4 can be fine-tuned as needed. The fastening of bolts and nuts ensures the firm connection between the moving wheel 4 and the pad 25, thereby enhancing the stability of the overall structure.

[0030] Two push handles 121 are symmetrically arranged on the front side of the tank body 1, so that the operator can better control and guide when moving the metal powder transfer tank. The spacing and setting height of the push handles 121 should be determined according to ergonomic principles to ensure that the operator can operate comfortably and safely. According to the general guidelines of ergonomics, the height of the optimal working area of ​​the arm is approximately between 70 and 135 cm. As for the spacing of the push handles 121, it should be wide enough so that both hands can hold it comfortably, but it should not be too wide so that the operator needs to overextend his arms. Generally speaking, the spacing of the push handles 121 can be determined according to the shoulder width of the operator, and usually this spacing will be between 40 and 50 cm to accommodate the shoulder width of most adults. Therefore, the setting height of the push handle 121 should be within this range to accommodate operators of different heights. The push handle 121 takes ergonomics into consideration. During the transportation process, whether it is pushing or pulling the transfer tank, the operation is easier and the labor intensity is reduced. At the same time, the symmetrical setting of the push handle 121 also helps to keep the tank body 1 balanced when moving to ensure safety. In summary, the setting height and spacing of the push handles 121 should take into account the comfort and efficiency of operation, while also meeting safety standards.

[0031] The inner surface of the tank body 1 is mirror polished, and the inner surface is highly polished (so that the roughness is maintained at R a 0.28~0.4 microns), so that it can reach the smoothness close to the mirror surface. The flow resistance of the metal powder is reduced and the unloading efficiency of the metal powder is improved. In addition, the smooth surface is easy to clean and maintain, and the service life of the tank body 1 is extended.

[0032] The tank body 1 is composed of a round cover 11, a round bin body 12, and a conical bin body 13 from top to bottom, and the corners of the connection between the round bin body 12 and the conical bin body 13 are arc-shaped. In this embodiment, the round cover 11 is located at the top of the tank body 1, providing a seal for the tank body 1 to prevent dust leakage and external pollution; the round bin body 12 is immediately below the round cover 11, providing sufficient space to store metal powder; the conical bin body 13 is located below the round bin body 12, and its conical design helps the powder flow to the discharge port 131 by gravity. The connection between the round bin body 12 and the conical bin body 13 adopts an arc transition, which reduces the accumulation of powder during the transfer process, prevents the generation of dead corners, and facilitates cleaning and maintenance.

[0033] The breathing port 112 with a filter is provided above the round cover 11, which is a common design for maintaining the pressure balance inside and outside the tank body 1 and preventing dust and other pollutants from entering the tank body 1. Three lifting rings 113 are evenly arranged circumferentially above the round cover 11 to facilitate the lifting and handling of the metal powder transfer tank. The three lifting rings 113 are distributed at 120° between each other to ensure the stability of the tank body 1 during the transportation process, prevent the tank body 1 from tilting or rotating during the lifting process, and play a role in protecting the tank body 1.
