Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] ReferenceFigures 1-5 A screening device for the production and processing of spheroidizing agents includes a cylinder 1 with multiple legs installed at its bottom. A feed pipe 2 extending into the cylinder 1 is located at its top. A screening screen 3, surrounding the feed pipe 2, is fixed to the inner wall of the top of the cylinder 1 for screening spheroidizing agents. A central cylinder 4, whose top end abuts against the screening screen 3, is fixed to the inner wall of the bottom of the cylinder 1. A crossbar 5 is fixed inside the central cylinder 4. An electric push rod 6 is fixed to the top of the crossbar 5. The output shaft of the electric push rod 6 is connected to a motor 7. The output shaft of the motor 7 is connected to a T-shaped base 8 whose outer edge can be attached to the screening screen 3. An integrally formed central shaft 9 is located on the top of the base 8. Multiple annular arrays of spheroidizing agents are distributed on the outer circumference of the central shaft 9. The bottom end of the material distribution plate 10 is connected to the chassis 8. The top of the central cylinder 4 has an upper opening 11 that matches the size of the chassis 8. When the electric push rod 6 is started, the output shaft of the electric push rod 6 drives the motor 7 and the chassis 8 to move upward into the screening cylinder 3. Then the motor 7 is started, and the output shaft of the motor 7 drives the chassis 8 and the material distribution plate 10 to rotate. Then the spheroidizing agent to be screened is put into the cylinder 1 through the feed pipe 2. The material distribution plate 10 drives the spheroidizing agent to rotate and pushes the spheroidizing agent to the screening cylinder 3 for screening. This effectively avoids the spheroidizing agent from always staying in the same position for screening. It allows the spheroidizing agent to be screened out at any position along the circumference of the screening cylinder 3, thereby improving the overall screening efficiency.

[0027] Furthermore, the central cylinder 4 is wider at the top and narrower at the bottom, and the size of the upper opening 11 is smaller than the maximum inner diameter of the central cylinder 4. The bottom end of the central cylinder 4 has a lower opening 18, and the bottom end of the cylinder 1 has a first discharge pipe 12 that communicates with the lower opening 18. After screening is completed, the electric push rod 6 is started to return to the initial height, so that the chassis 8 enters the central cylinder 4. At this time, the motor 7 is started again, and the output shaft of the motor 7 drives the chassis 8 to rotate, throwing out the spheroidizing agent that has not been screened out accumulated on the chassis 8. This part of the spheroidizing agent falls from the position between the chassis 8 and the central cylinder 4 and is discharged through the first discharge pipe 12.

[0028] Furthermore, a guide plate 13 inclined to one side is fixed on the inner surface of the cylinder 1 and sleeved on the central cylinder 4. A second discharge pipe 14 is provided at the lower position of the guide plate 13. The bottom end of the second discharge pipe 14 passes through the bottom of the cylinder 1. The spheroidizing agent screened by the central cylinder 4 falls onto the guide plate 13 and then discharges through the second discharge pipe 14.

[0029] Furthermore, a semi-enclosed feed hood 15 is fixed at the top of the cylinder 1 above the feed pipe 2. The spheroidizing agent is put into the cylinder 1 through the enclosed feed hood 15 to prevent the spheroidizing agent from spilling to the outside during feeding.

[0030] Furthermore, the material distribution partition 10 is provided with an installation port 16, and multiple evenly distributed partition plates 17 are fixed in the installation port 16. The partition plates 17 have a "<" shaped cross section. When the chassis 8 rotates, the spheroidizing agent located between two adjacent material distribution partitions 10 can flow through the gap between the two partition plates 17, thereby preventing the spheroidizing agent from always staying between the two material distribution partitions 10 in the same group, thereby further improving its screening efficiency. When the spheroidizing agent is thrown out, it can bounce when it hits the surface of the "<" shaped partition plate 17, causing the spheroidizing agent to collide, thereby making its trajectory range larger, thereby further improving the screening efficiency.

[0031] Furthermore, the top of the chassis 8 is provided with multiple circular arrays of bulk material components located between the two material distribution plates 10. The bulk material components disperse the spheroidizing agent along the arc direction, thereby increasing the trajectory range of the ejected agent and further improving the screening efficiency.

[0032] Furthermore, the bulk material assembly includes a pair of fixed blocks 19 fixed on the chassis 8. The two fixed blocks 19 are rotatably connected to the same shaft 20. A sleeve 21 is fixedly fitted on the shaft 20. The outer circumference of the sleeve 21 is provided with multiple annular arrayed bulk material blades 22. When the spheroidizing agent impacts the bulk material blades 22, the bulk material blades 22 will rotate around the axis of the shaft 20, and the rotating bulk material blades 22 will disperse the spheroidizing agent along the arc direction.
