[0004] The purpose of this utility model is to provide an ultrafine powder separation equipment to solve the above-mentioned technical problems, to grade and screen ultrafine powder, and to improve production efficiency and product quality.

[0005] In view of this, the utility model provides an ultrafine powder separation equipment, including a first support frame and also including: a screening tube, which is arranged on the first support frame; a feed hopper, which is arranged above the screening tube; a discharge pipe, which is arranged below the screening tube away from the feed hopper; a screening hole, which is arranged at the bottom of the screening tube; and a transport component, which is arranged in the screening tube and pushes the material in the screening tube.

[0006] In this technical solution, material enters the screening tube from the feed hopper. Material with a smaller diameter than the screening holes at the bottom of the tube falls out of the tube, and the transport assembly pushes material with a larger diameter toward the discharge port. The transport assembly transports the screened material to prevent accumulation in the tube.

[0007] In the above technical solution, further, the sieve holes are arranged in a linear array along the length direction of the sieve tube in several groups. The farther the sieve holes are from the position of the feed hopper, the larger the diameter of the sieve holes.

[0038] Example 1:

[0039] In view of this, this embodiment provides an ultrafine powder separation device, such as Figure 1As shown, the first support frame 1 also includes: a screen tube 2, which is arranged on the first support frame 1; a feed hopper 3, which is arranged above the screen tube 2; a discharge pipe 4, which is arranged below the screen tube 2 on the side away from the feed hopper 3; a screen hole 8, which is arranged at the bottom of the screen tube 2; and a transport component 7, which is arranged in the screen tube 2 and pushes the material in the screen tube 2. The material enters the screen tube 2 from the feed hopper 3 and the screen hole 8 at the bottom of the screen tube 2. The material with a diameter smaller than the screen hole 8 falls out of the screen tube 2, and the transport component 7 pushes the material with a diameter larger than the screen hole 8 to the discharge port. The transport component 7 transports the screened material to prevent the material from accumulating in the screen tube 2.

[0040] like Figure 2 As shown, several groups of screening holes 8 are arranged in a linear array along the length of the screening tube 2. The further away from the feed hopper 3 the screening holes 8 are, the larger their diameters become. Each screening hole 8 is associated with a collection hopper 6 fixed to the outer wall of the screening tube. The diameter of the screening holes 8 is adjusted to classify the screened material. The collection hopper 6 directs the material that falls from the material tube.

[0041] like Figure 3 As shown, the transport assembly 7 includes a first motor 701, which is fixedly mounted on one side of the screen tube 2. The output end of the first motor 701 passes through the side wall of the screen tube 2 and is coaxially connected to a conveyor shaft 702. The conveyor shaft 702 is rotatably mounted within the screen tube 2, and a conveyor blade 703 is spirally mounted on the surface of the conveyor shaft. The motor drives the conveyor shaft 702 to rotate, which in turn drives the conveyor blades 703 to rotate. The conveyor blades 703 push the material within the screen tube 2 and push the material out of the feed hopper 3 and toward the discharge pipe 4.

[0042] like Figure 4As shown, the fixing assembly 9 includes a fixing column. One end of the fixing column is fixedly mounted on the top of the first support frame 1, and the other end is fixedly mounted on the bottom of the first fixing frame 901. A second fixing frame 902 is arranged above the first fixing frame 901. A connecting assembly is connected between the second fixing frame 902 and the second fixing frame 902. The connecting assembly connects the first fixing frame 901 and the second fixing frame 902. The first fixing frame 901 and the second fixing frame 902 are sleeved on the outer wall of the screen tube 2. The fixing column provides support for the first fixing frame 901, and the first fixing frame 901 provides support for the sub-screen tube. The adjustment assembly enables the second fixing frame 902 to cooperate with the first fixing frame 901 to fix the screen tube 2. The shape of the first fixing frame 901 and the second fixing frame 902 is horizontal on both sides and an arc-shaped fixing frame in the middle. The shape of the first fixing frame 901 and the second fixing frame 902 makes it easier to fix the screen tube 2. The connecting assembly includes a first screw 904, which is symmetrically arranged on both sides of the first fixing frame 901 and the second fixing frame 902. The first screw 904 is threadedly connected to a first nut 905, which is arranged below the first fixing frame 901. By manually rotating the first nut 905, the first nut 905 cooperates with the first screw 904 to move the first fixing frame 901 and the second fixing frame 902 closer to each other. The cooperation between the first screw 904 and the first nut 905 forms a snap-fit ​​structure between the first fixing frame 901 and the second fixing frame 902.

[0043] like Figure 6 As shown, it also includes a vibration assembly 5, which includes a second support frame 501, the second support frame 501 is fixedly arranged on the first support frame 1, and a second motor 502 is arranged on the second support frame 501. The output end of the second motor 502 is coaxially connected to the eccentric disc 503, the surface of the eccentric disc is attached to the bottom of the outer wall of the screen tube 2, and a shock absorbing unit is arranged between the screen tube 2 and the first support frame 1, and the shock absorbing unit provides a shock absorbing effect for the screen tube 2. The second motor 502 drives the eccentric disc 503 to rotate, and the rotation of the eccentric disc 503 provides vibration to the screen tube 2 to prevent the screen hole 8 from being blocked. Since the screen tube 2 is provided with a shock absorbing unit, the shock absorbing unit provides a shock absorbing effect for the screen tube 2, which reduces equipment wear.

[0044] like Figure 5 As shown, the shock absorbing unit includes a first spring 10, which is sleeved on a fixed column, which is a hydraulic column 903. One side of the first spring 10 is connected to the top of the first support frame 1, and the other side is connected to the bottom of the first fixed frame 901. The hydraulic column 903 provides expansion and contraction to assist the first spring 10 during support. The first spring 10 provides shock absorption for the screen pipe 2 through its own deformation change.

[0045] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
