[0036] The separation tank body 100 is used to contain the mixed solution containing the metal powder one and the metal powder two, and it should be noted that the metal powder one is a metal powder particle with large size particles, and the metal powder two is a metal powder with small size particles (micro-nano level), and the mixed liquid of the two is placed in the separation tank body 100 after stirring treatment, and after settling for a predetermined time, the large size metal powder one is located at the bottom end of the separation tank body 100 under the action of gravity, and the small size metal powder two is less affected by gravity and can be suspended at the top end of the separation tank body 100. At this time, by collecting the liquid at the top end of the separation tank body 100, the efficient separation process of the metal powder one and the metal powder in the separation tank body 100 can be realized, so as to reduce the problem of difficult filtration and filtration blockage in the subsequent processing process, reduce the burden of the filtration element, and the purity of the metal powder two collected by the method is greater than 99% after drying and purification.

The metal powder continuous separation device according to claim 5, characterized in that: The inner wall of the separation tank body (100) is provided with a flow guide device (600), the flow guide device (600) comprises a flow guide cover connected to each other from top to bottom, the flow guide cover comprises a flow guide body 1 (610) and a flow guide body 2 (620), and the inclination gradient of the flow guide body 1 (610) is greater than the inclination gradient of the flow guide body 2 (620).

7. The metal powder continuous separation device according to claim 6, characterized in that: The side wall of the hollow mounting rod (700) is fixedly connected with a settling blade (630), and the settling blade (630) is located between the first flow guide body (610) and the second flow guide body (620).

8. A method for continuous separation of metal powder, characterized in that: The metal powder continuous separation device according to any one of claims 5 to 7 comprises the following steps: S1, adding a mixed solution containing metal powder 1 and metal powder 2 into the separation tank (100) until the liquid level is higher than the bottom of the solution delivery pipe (210), completing separation preparation; S2. After the separation preparation in step S1 is completed, the delivery pump is started to control the directional flow of the liquid. The solution containing the second metal powder at the top of the separation tank (100) is sucked into the filtering device (300) through the solution delivery pipe (210), thereby filtering the second metal powder and the liquid and completing the powder separation. S3. After the powder separation in step S2 is completed, the separated liquid flows out from the bottom end of the hollow mounting rod (700) and flows back into the interior of the separation tank (100), completing the liquid reflux replenishment.

9. The method for continuous separation of metal powder according to claim 8, characterized in that: After the delivery pump body is started to control the directional flow of the liquid, the second electronic control device (710) controls the rotation of the hollow mounting rod (700), and the top end cleans the metal powder 2 on the surface of the filter cover (320) through the spiral cleaning blade (360), and the bottom end stirs the mixed solution through the stirring assembly (500).
