Description

Technical Field

[0001] The utility model relates to the technical field of powder collecting cans, in particular to a sealed powder collecting can. Background Art

[0002] In the powder preparation process of high-frequency induction plasma spheroidization equipment, industrial gas can be used to protect the powder and prevent the powder from being contaminated by impurities in the air or other gases. Generally, nitrogen or argon is injected into the reaction chamber to create an environment filled with inert gas, thereby ensuring the purity and quality of the powder.

[0003] However, in the process of transferring powder, the traditional powder collection tank needs to open the bottle mouth to transfer the powder in the tank to other containers. This process can easily cause air or other gas impurities to enter the tank, causing the prepared powder to be affected by oxidation or other chemical reactions, thereby affecting the purity of the powder and causing certain quality problems.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Embodiment 1:

[0022] Reference Figure 1 , a sealed powder collection tank disclosed in the utility model, includes a tank body 1 with a hollow interior, the tank body 1 is in a columnar shape that is narrow at the top and wide at the bottom, the cross-section of the tank body 1 is in an isosceles trapezoid, a cylindrical connecting section is provided at the narrower end of the tank body 1, both ends of the connecting section are opened and communicated with the inner cavity of the tank body 1, and a circular connecting block 11 is provided at the end of the connecting section away from the tank body 1.

[0023] Reference Figure 1, a sealing section 2 is provided at one end of the tank body 1 where the connecting section is located, and both ends of the sealing section 2 are open. The opening at one end adjacent to the tank body 1 is used to connect to the inner opening 3 of the tank body 1, and the opening at one end away from the tank body 1 is used to connect to the outer opening 4 of other equipment or containers. In this embodiment, the sealing section 2 is in the shape of a long cylinder, and the inner opening 3 and the outer opening 4 are coaxially arranged, and the diameter length of the inner opening 3 and the outer opening 4 is consistent. A sealing baffle 5 is rotatably arranged in the sealing section 2, and the sealing baffle 5 is located between the inner opening 3 and the outer opening 4. The sealing baffle 5 can play the role of closing the sealing section 2 from the outside. A switch valve 6 is provided outside the sealing section 2. Under the control of the switch valve 6, the operator can open or close the sealing section 2 by rotating the sealing baffle 5. There can be multiple sealing baffles 5 in the sealing section 2, and each sealing baffle 5 corresponds to a switch valve 6. Multiple sealing baffles 5 are arranged at intervals in the sealing section 2 without interfering with each other.

[0024] Reference Figure 1 , both ends of the sealing section 2 are provided with a fixing block 23, the fixing block 23 is in a circular ring shape and the diameter of the fixing block 23 is consistent with the diameter of the connecting block 11, the fixing block 23 located at the end of the sealing section 2 close to the tank body 1 is in contact with the connecting block 11, and a quick-release chuck 7 is provided at the connection between the fixing block 23 and the connecting block 11, and the sealing section 2 is connected to the tank body 1 through the quick-release chuck 7.
