The metal magnesium powder belongs to inflammable and explosive substances, and is used for isolating air in the transferring and transporting processes. Therefore, the invention provides a material transfer device which can isolate magnesium powder from air for storage, transportation and transfer.
The material transfer device provided in this embodiment is composed of a magnesium powder storage and transportation tank 101 and a connecting pipeline. The magnesium powder storage and transportation tank 101 shown in fig. 1 is a cylindrical barrel and an elliptical head. In other embodiments, the magnesium powder storage tank 101 may be a rectangular or square container, and the seal head may be a dished seal head, a hemispherical seal head, a conical seal head, a flat bottom seal head, or a combined seal head.

The magnesium powder storage and transportation tank 101 is provided with a material inlet, a material outlet and an argon pipeline and an argon inlet 105, and argon can be pressurized in the magnesium powder storage and transportation tank 101 after entering the magnesium powder storage and transportation tank. Argon as inert gas does not react with magnesium powder. If the material is other powder, other gases that do not react with the powder may be used instead of argon in this embodiment. A magnesium powder inlet ball valve 102 is arranged at the material inlet, and a magnesium powder outlet ball valve 103 is arranged at the material outlet. When the material is powder or liquid, the material is sunk downward by gravity, and therefore, the magnesium powder storage and transportation tank 101 should be placed vertically, the material inlet is disposed above the magnesium powder storage and transportation tank 101, and the material outlet is disposed below the magnesium powder storage and transportation tank 101, as shown in fig. 1.
A gas inlet ball valve 104 is provided at the argon gas inlet 105. The argon gas pipeline can be directly connected to the magnesium powder storage and transportation tank 101, as shown in fig. 1, 4 and 6. An argon gas line may also be connected to the line between the magnesium powder inlet ball valve 102 and the magnesium powder storage tank 101, as shown in fig. 2, 5, 7. Preferably, an argon pipeline evacuation ball valve 106 is additionally arranged on the argon pipeline. The ball valves can also be stop valves, electromagnetic valves or start ball valves.
The magnesium powder storage and transportation tank 101 is provided with a pressure gauge 107. The pressure gauge 107 may be mounted on a tank, such as the pressure gauge 107 in fig. 1. In other embodiments, the pressure gauge may be mounted on the head, and may also be mounted on the line of the material inlet. The pressure gauge can be a gauge pressure gauge or an absolute pressure gauge, and the inlet of the pressure gauge can be connected with a gauge valve or a ball valve. The pressure gauge may also be a pressure transmitter.
The connecting pipeline is an important component of the material transfer device, and the structure of the connecting pipeline is shown in fig. 3. The connecting line is a Y-shaped line and the main body is a metal hose 201. The two ends of the main pipe of the connecting pipeline can be respectively connected to the material inlet or the material outlet of the magnesium powder storage and transportation tank 101 according to the requirement. Preferably, the main pipe is provided with a valve at each end, such as the connecting line ball valve 202 and the connecting line ball valve 203 shown in fig. 3. If the magnesium powder in the magnesium powder storage tank 101 can be completely transferred to a container or equipment to be filled with the magnesium powder, so that no residual materials exist in the connecting pipeline, the connecting pipeline ball valve 202 and the connecting pipeline ball valve 203 can be omitted. The branch pipe of the connecting pipeline is provided with a vacuum pumping ball valve 204 for connecting a vacuum pump, and the material transfer device needs to be used together with the vacuum pump and an argon bottle.
The workflow of the material transfer apparatus will be described in detail below using magnesium powder transfer as an example.

3. The vacuum pump is started to vacuumize the magnesium powder storage and transportation tank 101 and the connecting pipeline, and the reading of the pressure gauge 107 is observed in real time. When the pressure gauge 107 shows a pressure around-0.1 MPa and the pressure is stable and no longer continuously drops, the vacuum ball valve 204 is closed and then the vacuum pump (not shown in the figure) is turned off.
4. And opening a pipeline valve of the magnesium powder source container (or equipment), wherein the air pressure in the magnesium powder storage and transportation tank 101 is very low and is far smaller than the air pressure in the magnesium powder source container (or equipment), and the magnesium powder in the magnesium powder source container (or equipment) starts to be filled into the magnesium powder storage and transportation tank 101 under the action of the relatively high air pressure of the magnesium powder source container (or equipment) until all the magnesium powder is transferred. In the magnesium powder transferring process, magnesium powder can be completely filled into the storage and transportation container 101 by vibrating the magnesium powder storage and transportation container 101 and a connecting pipeline.

The connecting pipeline and a magnesium powder pipeline valve (not shown) of a magnesium powder container (or equipment) (not shown) to be filled are connected together, and the connecting pipeline ball valve 203 is specifically connected to the magnesium powder pipeline valve of the magnesium powder container to be filled.
2. The argon bottle neck valve (not shown) and the argon line purge ball valve 106 were opened, the argon inlet line was purged of air with a small amount of argon, and then the argon line purge ball valve 106 was closed.
3. The vacuum pumping ball valve 204, the connecting pipeline ball valve 202, the connecting pipeline ball valve 203 and valves on magnesium powder pipelines needing to be filled into magnesium powder containers (or equipment) are opened, and a vacuum pump is started to vacuumize the connecting pipeline between the two containers and the containers needing to be filled with magnesium powder.
4. Looking at the pressure gauge 107, when the pressure gauge 107 shows a pressure around-0.1 MPa and the pressure is stable, the vacuum ball valve 204 is closed and then the vacuum pump is turned off again.
5. And opening the magnesium powder outlet ball valve 103, then opening the argon inlet ball valve 104 and an argon bottle opening valve, and conveying the magnesium powder in the magnesium powder storage and transportation tank 101 to a container (or equipment) needing to be filled with the magnesium powder by utilizing the pressure of argon. During the transfer process, magnesium powder can be completely filled into a container (or equipment) needing to be filled with magnesium powder through vibrating the magnesium powder storage and transportation tank 101 and a connecting pipeline.
6. After the transfer is completed, the magnesium powder outlet ball valve 103, the connecting pipeline ball valve 202, the connecting pipeline ball valve 203 and pipeline valves of the container (or equipment) with the magnesium powder are closed, the connection between the connecting pipeline ball valve 202 and the magnesium powder inlet ball valve 103 is disconnected, the connection between the connecting pipeline ball valve 203 and the pipeline valves of the container (or equipment) with the magnesium powder is disconnected, and then the connecting pipeline is taken down. If the volume of the container (or equipment) into which the magnesium powder is to be loaded is small, the remaining magnesium powder is stored in the magnesium powder storage tank 101 and the connecting pipeline by isolating air. Residual magnesium powder in the connecting pipeline is stored in the connecting pipeline by isolated air, and the magnesium powder in the connecting pipeline can be recycled in a vacuum environment.
