The device includes a main body, a control mechanism fixedly installed on one side of the outer wall of the main body, and a vibration mechanism fixedly installed on one side of the outer wall of the main body. The vibration mechanism includes a motor.

[0004] The above-mentioned device, through the cooperation of the main structure and the vibration mechanism, when the slag is poured in from the discharge port, the motor first drives one crusher to rotate through the pulley and belt, and drives another crusher to rotate through the gear to crush the slag. Then the motor third generates vibration through the eccentric block to perform multi-stage screening of the slag.

[0005] The aforementioned device crushes the slag using a crusher, and then uses an eccentric block to generate vibration to crush and screen the slag. However, the device requires the integration of multiple different mechanical components to crush and screen the slag, resulting in too many parts inside the device, occupying space and making it difficult to waste energy.

[0006] In view of this, this utility model is hereby proposed. Utility Model Content

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This slag micro powder screening device, through the cooperation of internal components of the screening assembly, the movable block drives the crushing block to move along the same trajectory. When the crushing block moves, it crushes the slag. The slag is driven by the crushing block and moves up and down, thereby fully crushing the slag.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0031] Please see Figure 1-5A slag micro powder screening device includes a base 1, on which a housing 11 is fixedly connected. The housing 11 is inclined and has a conical bottom. A feed inlet 12 is fixedly connected to the top of the housing 11. A screening assembly is disposed inside the base 1 and is used to crush and screen the slag. The screening assembly includes a screening cylinder 2, a transmission rod 3, and crushing blocks 4. The screening cylinder 2 is rotatably disposed inside the base 1. The transmission rod 3 is disposed in the middle of the screening cylinder 2 and is drivenly connected to the base 1 and rotatably connected to the screening cylinder 2. The crushing blocks 4 are arranged in an array on the transmission rod 3 and are movably connected to the transmission rod 3. Through the cooperation of the internal components of the screening assembly, the movable block 32 drives the crushing blocks 4 to move along the same trajectory. When the crushing blocks 4 move, they crush the slag. The slag is driven by the crushing blocks 4 and moves up and down, thereby fully crushing the slag. After being crushed, the slag is screened outward by the centrifugal force of the crushing blocks 4 and the screening cylinder 2, reducing the space occupied in the device and reducing energy consumption.

[0032] The crushing block 4 consists of a fan-shaped block and two arc blocks. The fan-shaped block is located at the end of the crushing block 4, and the arc blocks are symmetrically located at the bottom of the crushing block 4. There is a gap between the arc blocks and the fan-shaped block. The crushing block 4 consists of a fan-shaped block and two arc blocks. When the crushing block 4 comes into contact with the slag, the slag is fully crushed through triangular contact and arc-shaped crushing.

[0033] The transmission rod 3 is equipped with multiple fixed blocks 31, which are fixedly connected to the transmission rod 3. Each fixed block 31 is fixedly connected to a spring 33, and each spring 33 is fixedly connected to a movable block 32. Each movable block 32 is slidably connected to the transmission rod 3. Connecting blocks 41 are arranged in an array on the movable block 32, and the connecting blocks 41 are fixedly connected to the movable block 32. Each connecting block 41 is rotatably connected to a connecting rod. The crushing block 4 is fixedly connected to the connecting rod. When the transmission rod 3 rotates, it generates centrifugal force, which drives the movable block 32 to rotate and stretches the spring 33. The spring 33 deforms and applies the deformation force to the movable block 32. Due to the centrifugal force and the elastic force of the spring 33, the movable block 32 slides back and forth on the transmission rod 3 while rotating. The movable block 32 drives the crushing block 4 to move along the same trajectory. When the crushing block 4 moves, it crushes the slag. The slag is driven by the crushing block 4 and moves up and down, thereby fully crushing the slag.

[0034] The bottom end of the screening cylinder 2 is rotatably connected to a protective shell 21. The protective shell 21 is fixedly connected to the inner wall of the base 1. The inner wall of the protective shell 21 is fixedly connected to a drive motor 22. The output shaft of the drive motor 22 is fixedly connected to a drive gear 23. The two sides of the drive gear 23 are meshed with a transmission gear 24 and a gear ring 25. The gear ring 25 is fixedly connected to the bottom end of the screening cylinder 2. The transmission gear 24 is fixedly connected to the bottom end of the transmission rod 3. The drive motor 22 drives the drive gear 23 to rotate through the output shaft. The drive gear 23 meshes with the transmission gear 24 and the gear ring 25. The transmission gear 24 and the gear ring 25 rotate in opposite directions. The transmission gear 24 drives the transmission rod 3 to rotate. The gear ring 25 drives the screening cylinder 2 to rotate. The screening cylinder 2 and the transmission rod 3 rotate in opposite directions.

[0035] The feed inlet 12 is equipped with multiple baffles, which are fixedly connected to the feed inlet 12. The baffles are inclined and their inclination directions are opposite to each other. The baffles block the slag powder in the screening cylinder 2 to prevent the slag powder from overflowing and affecting the external environment.

[0036] Working principle: The slag is manually fed into the screening cylinder 2 through the feed inlet 12. The drive motor 22 drives the drive gear 23 to rotate via the output shaft. The drive gear 23 meshes with the transmission gear 24 and the gear ring 25. The transmission gear 24 and the gear ring 25 rotate in opposite directions, driving the transmission rod 3 to rotate. The gear ring 25 drives the screening cylinder 2 to rotate, and the screening cylinder 2 rotates in opposite directions with the transmission rod 3. The rotation of the transmission rod 3 generates centrifugal force, which drives the movable block 32 to rotate and stretches the spring 33. The spring 33 deforms, applying the deformation force to the movable block 32. Due to the centrifugal force and the elastic force of the spring 33, the movable block 32 slides back and forth on the transmission rod 3 while rotating. The movable block 32 drives the crushing block 4 to move along the same trajectory. The crushing block 4 crushes the slag during its movement. The slag is driven by the crushing block 4 and... The slag is crushed by moving up and down. After being crushed, the slag is screened outward by the centrifugal force of the crushing block 4 and the screening cylinder 2. Through the cooperation of the internal components of the powder screening assembly, the slag is crushed and screened mechanically, reducing the space occupied in the device and reducing energy consumption. The crushing block 4 consists of a fan-shaped block and two arc blocks. When the crushing block 4 comes into contact with the slag, the slag is fully crushed by the triangular contact and arc crushing. When the movable block 32 rotates, it drives the connecting block 41. The connecting block 41 is rotatably connected to the connecting rod. When the connecting block 41 moves, the connecting rod and the connecting block 41 swing due to the size of the slag. After swinging, the connecting rod applies a secondary impact force through centrifugal force, crushing the slag multiple times. At the same time, the crushing block 4 hits the wall of the screening cylinder 2, and the screening cylinder 2 vibrates, shaking the mineral debris off the screening cylinder 2, thereby achieving self-cleaning.
