The properties of metal powder are generally divided into chemical properties, physical properties, and process properties. Chemical properties refer to the metal content and impurity content. Physical properties include the average particle size and particle size distribution of the powder, the specific surface area and true density of the powder, the shape, surface morphology, and internal microstructure of the particles. Process performance is a comprehensive performance, including the fluidity, bulk density, tap density, compressibility, formability, and sintering size change of the powder.

[0032] Working principle:

[0033] When it is necessary to separate the cylinder 1 and the filter seat 2 adapted to the cylinder 1, the staff presses the first push plate 212 and the second push plate 1502 downwards respectively, and the first push plate 212 and the second push plate 1502 respectively drive the first rotating plate 211 and the second rotating plate 1501 fixedly connected thereto to move, and the first rotating plate 211 and the second rotating plate 1501 are respectively rotatably connected to the first support rod 8 and the second support rod 9, so the first rotating plate 211 and the second rotating plate 1501 move on the first support rod 8 and the second support rod 9 respectively.

[0034] Since the applied force is downward, the front ends of the first rotating plate 211 and the second rotating plate 1501 move upward respectively, and the rear ends of the first rotating plate 211 and the second rotating plate 1501 move downward respectively. When the front end of the first rotating plate 211 moves upward, it drives the first push rod 213 hinged to its front end to move upward. The first push rod 213 is adapted to the front side of the first rack 6, so the first push rod 213 pushes the first rack 6 to slide upward in the first slide groove 217 on the first connecting rod 4. At the same time, the rear end of the first rotating plate 211 drives the second push rod 214 hinged to it to move. The second push rod 214 is adapted to the rear side of the first rack 6, so the second push rod 214 slides downward on the rear side of the first rack 6.

[0035] Similarly, when the front end of the second rotating plate 1501 moves upward, it drives the third push rod 1503 hinged to its front end to move upward, and the third push rod 1503 is adapted to the front side of the second rack 7, so the third push rod 1503 pushes the second rack 7 to slide upward in the second slide groove 1505 on the second connecting rod 5. At the same time, the rear end of the second rotating plate 1501 drives the fourth push rod 1504 hinged to it to move, and the fourth push rod 1504 is adapted to the rear side of the second rack 7, so the fourth push rod 1504 slides downward on the rear side of the second rack 7.

[0036] When the first push rod 213 and the third push rod 1503 touch the first limit plate 215 on the first rotating plate 211 and the second rotating plate 1501 respectively, the staff stops applying downward force, and at this time pushes the first push plate 212 and the second push plate 1502 upward, and the first push plate 212 and the second push plate 1502 respectively drive the first rotating plate 211 and the second rotating plate 1501 to move, and the first rotating plate 211 and the second rotating plate 1501 are respectively connected to the first supporting rod 8 and the second supporting rod 9 through the first rotating plate 211 and the second rotating plate 1501. The movable plate 1501 moves on the first support rod 8 and the second support rod 9 respectively. Since the force applied is upward, the front ends of the first rotating plate 211 and the second rotating plate 1501 move downward respectively, and the rear ends of the first rotating plate 211 and the second rotating plate 1501 move upward respectively. The first rack 6 is pushed upward again by the second push rod 214 on the rear end of the first rotating plate 211, and the second rack 7 is pushed upward again by the fourth push rod 1504 on the rear end of the second rotating plate 1501, so as to realize the sliding of the first rack 6 and the second rack 7 again. The above steps are repeated to make the first rack 6 and the second rack 7 slide upward all the time.

[0037] When the first rack 6 and the second rack 7 move, the fixed ring 3 fixedly connected thereto is driven to move, and the movement of the fixed ring 3 drives the cylinder 1 fixedly connected thereto and the telescopic rod 15 to move. The telescopic rod 15 is used to limit and support the fixed ring 3 and the cylinder 1 on the fixed ring 3, so that the cylinder 1 and the filter seat 2 are separated. By separating the cylinder 1 from the filter seat 2, the filter device is opened, which is convenient for the staff to use and improves the staff's work efficiency.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the utility model.
