Description

Technical Field

[0001] This utility model belongs to the field of aluminum powder production technology, and in particular relates to an aluminum powder vibrating screen with a flow guiding and separation function. Background Technology

[0002] In industrial production, aluminum powder is widely used in automobiles, aerospace, electronics, and other fields. However, during the production process (or in recycled aluminum powder), particles of varying sizes inevitably appear. Therefore, it is necessary to screen the aluminum powder to separate the larger particles. Current technology often uses vibrating screens for screening aluminum powder. However, existing vibrating screens have several problems. For example, if too much aluminum powder is added at once after being conveyed to the vibrating screen via a conveyor belt, it often causes screen blockage and incomplete screening, resulting in smaller particles being carried out of the screen along with larger particles. Conversely, adding too little powder at once affects screening efficiency. Therefore, in current technology, the amount of aluminum powder added affects both screening efficiency and quality, leading to incomplete particle screening and low screening efficiency. Utility Model Content

[0003] To address the technical problems of incomplete aluminum powder particle screening and low screening efficiency in existing technologies, this utility model provides an aluminum powder vibrating screen with a flow guiding and separation function. The screen includes a horizontally positioned base that provides support. Several supporting columns are fixed to the top of the base. A vertically positioned, open-top shell is located above the base. Support legs, corresponding to the columns, are located at the bottom of the shell, and springs acting as buffers are installed between the legs and columns. Several vibration motors are located at the bottom of the shell. When the vibration motors are activated, the shell vibrates irregularly under the action of the motors and springs. A vertically positioned storage tank is located on the top of the housing. The top of the storage tank is open, and the lower end of the storage tank is fixed to the upper end of the housing via a storage tank bracket. A feeding mechanism is located at the bottom of the storage tank. The feeding mechanism includes a horizontally positioned rotating shaft with several feeding blades evenly spaced along the circumference of the rotating shaft. Both ends of the rotating shaft are rotatably mounted on the storage tank via bearings. A drive motor is fixed to the outside of the storage tank. The power output shaft of the drive motor is connected to the rotating shaft. The drive motor is powered by a cable. When the drive motor is started, it drives the feeding blades to rotate via the rotating shaft. The feeding blades feed the aluminum powder material in the storage tank out of the storage tank. The upper part of the shell is equipped with a flow guiding mechanism, which includes a distribution cone located directly below the storage tank. Several support rods are provided between the distribution cone and the inner wall of the shell for support. It also includes several downwardly inclined first screens, evenly spaced around the distribution cone. Baffles are fixed to both sides of the top of each first screen, and the first screens are trapezoidal in shape, wider at the top and narrower at the bottom. Aluminum powder from the storage tank falls onto the distribution cone, and then the material is distributed to each of the first screens. Under the action of the first screens, small particles... Aluminum powder falls onto the second screen. Large particles of aluminum powder, after being screened by the first screen, fall into the collection trough and are discharged from the shell through the first discharge port. Large particles of aluminum powder screened by the second screen also fall along the second screen into the collection trough and are discharged from the first discharge port. Fine aluminum powder falls into the shell below the second screen and is discharged from the shell through the second discharge port at the bottom of the shell. The second screen is conical, and its filter holes are smaller than those of the first screen, enabling multi-layer screening of the material inside the shell, increasing screening efficiency and screening quality. A horizontally arranged support ring is located at the lower end of the shell's interior. The second screen is fixed to the top of the support ring, and an annular collection trough is formed at the top of the support ring. Several first discharge ports, each corresponding to a first screen, are also included, connected to the bottom of the collection trough.

[0004] Preferably, at least three first screens are provided.

[0005] Preferably, the lower cross-sectional area of ​​the storage tank is smaller than the bottom area of ​​the distribution cone.

[0006] Preferably, the angle of the first screen is α, and 15°≤α≤60°.

[0007] Preferably, a plurality of feeding pipes corresponding to the first screen are fixed on the inner wall of the shell, with the top end of the feeding pipe located directly below the lower end of the first screen and the bottom end of the feeding pipe located above the collecting trough.

[0008] The above scheme has the following advantages:

[0009] The feeding mechanism controls the rotational speed of the shaft by controlling the speed of the drive motor, and controls the feeding speed of the aluminum powder by using the feeding blades to move the material, which greatly improves the uniformity of feeding. The guiding mechanism separates large aluminum powder particles through multiple first screens and allows smaller aluminum powder particles to be more evenly distributed on the second screen for a second screening. The second screen is cone-shaped, which increases the screening area and improves screening efficiency. Attached Figure Description
