[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A pyrolysis carbon black pulverization and granulation production line includes a pulverizing device and a granulation device connected together. The granulation device has a receiving hopper at its top and a granulation discharge port on its side wall, which is connected to a screening mechanism. The screening mechanism includes a screening chamber with a screening inlet connected to the granulation discharge port. An inclined plate is located at the bottom of the screening chamber, and a waste outlet at the bottom of the screening chamber cooperates with the inclined plate. A screen is installed inside the screening chamber at an angle, with one end of the screen near the discharge port lower and the other end higher. A screening discharge port on the side wall of the screening chamber cooperates with the lower end of the screen.

The crushing rollers are rotatably connected to the side wall of the screening chamber via a rotating shaft that penetrates the side wall of the screening chamber and is connected to a crushing motor.

[0007] As an improvement, a moving mechanism is installed between the rotating shaft and the side wall of the screening chamber. The moving mechanism includes a moving block, with the moving block rotatably connected to both ends of the rotating shaft. The crushing motor is fixedly connected to the moving block. The moving block is provided with a sliding groove, and the side wall of the screening chamber is provided with a slide rail that cooperates with the sliding groove. The sliding groove and the slide rail are slidably connected. The side wall of the screening chamber is provided with a vertically elongated through hole that cooperates with the rotating shaft. The moving block is threadedly connected to a vertically arranged screw, which is rotatably installed on the side wall of the screening chamber.

[0019] like Figure 1-4 As shown, a pyrolysis carbon black pulverization and granulation production line includes a pulverizing device and a granulation device 3, which are connected together. After being pulverized by the pulverizing device, the carbon black enters the granulation device for granulation. The top of the granulation device 3 is provided with a receiving hopper 1, which facilitates the receipt of carbon black powder and its injection into the granulation device 3. The granulation device 3 is provided with a granulation outlet 7, which is connected to a screening mechanism 9. After the carbon black powder is granulated, it can be conveyed from the granulation device 3 to the screening mechanism 9 through the granulation outlet 7. The carbon black granules produced by the granulation device 3 are discharged from the device after being screened by the screening mechanism 9.

[0020] The screening mechanism 9 includes a screening chamber 20, which is equipped with a screening inlet connected to a granulation outlet 7. Carbon black granules discharged from the granulation outlet 7 enter the screening chamber 20 through the screening inlet. The bottom of the screening chamber 20 is equipped with an inclined plate 16 and a waste outlet 17 that cooperates with the inclined plate 16. The falling material can slide naturally along the inclined plate 16 and be discharged from the waste outlet 17 to the outside of the device.

[0021] A screen 12 is snapped into the screening chamber 20. One end of the screen 12 is connected to the screening inlet. Material with excessively small particles can pass through the screen 12 and fall down, and be discharged from the waste outlet 17 along the inclined plate 16. The screen 12 is inclined, and the end of the screen 12 away from the screening inlet is lower than the end near the screening inlet and lower than the end away from the outlet. The side wall of the screening chamber 20 is provided with a screening outlet 15 that matches the lower end of the screen 12.

[0022] The screening mechanism 9 is equipped with a crushing component 14, which is located above the screen 12. The crushing component 14 includes several crushing rollers 13. There is a flow gap between the crushing rollers 13 and the screen 12. Particles of suitable size can pass through the flow gap and pass through the crushing rollers 13 without being crushed. Particles that are too large will be crushed by the crushing rollers 13. The crushed material will fall through the screen 12 and be discharged through the waste outlet 17. After collection, it will be granulated again. The crushing rollers 13 are rotatably connected to the side wall of the screening chamber 20 through a rotating shaft. The rotating shaft passes through the side wall of the screening chamber 20 and is connected to a crushing motor 11. The crushing motor 11 can make the rotating shaft and the crushing rollers 13 rotate. The material that is too large can pass through the crushing rollers 13 more smoothly and avoid the material getting stuck between the crushing rollers 13 and the screen 12. Preferably, a reinforcement device can be set at the corresponding position of the screen 12 and the crushing rollers 13 to prevent the screen 12 from being deformed too much during the extrusion process.

[0023] In this embodiment, after the carbon black is crushed by the crushing device, it enters the granulation device 3 through the receiving hopper 1 to granulate the carbon black powder. After granulation, the carbon black particles are fed into the screening chamber 20 through the granulation outlet 7 and the screening inlet for screening. Carbon black particles that are too small can fall directly through the screen 12 and be discharged from the waste outlet 17 along the inclined plate 16 to be collected outside the device. Carbon black particles that are too large are crushed by the screen 12 and the crushing roller 13, so that the carbon black particles that are too large fall through the screen 12 and are discharged from the waste outlet 17 along the inclined plate 16 to be collected outside the device. The carbon black discharged from the waste outlet 17 is collected, crushed and mixed, and can be used as raw material for granulation.

[0024] A moving mechanism 8 is installed between the rotating shaft and the side wall of the screening chamber 20. The moving mechanism 8 can adjust the position of the rotating shaft, thereby adjusting the distance between the crushing roller 13 and the screen 12, and controlling the particle size that can pass through the flow gap. The moving mechanism 8 includes a moving block 23, with the moving block 23 rotatably connected to both ends of the rotating shaft. The crushing motor 11 is fixedly connected to the moving block 23. The moving block 23 is provided with a sliding groove 21, and the side wall of the screening chamber 20 is provided with a slide rail 18 that cooperates with the sliding groove 21. The slide rail 18 is slidably connected, and the side wall of the screening chamber 20 is provided with a vertical elongated through hole 19 that cooperates with the rotating shaft. The rotating shaft moves along the vertical elongated through hole 19. The moving block 23 is threadedly connected to a vertically arranged screw 24. The screw 24 is rotatably installed on the side wall of the screening chamber 20. One end of the screw 24 is fixedly connected to a handwheel 22. By rotating the screw 24 through the handwheel 22, the moving block 23 moves up and down along the screw 24 under the limiting action of the slide rail 18 and the slide groove 21, thereby completing the adjustment of the rotating shaft.

[0025] A blower 10 is fixedly installed inside the screening chamber 20. The blower 10 is located above the screen 12 and between the screening feed inlet and the crushing component 14. The direction of the blower 10 is consistent with the inclination direction of the screen 12. The blower 10 can blow away the granular carbon black particles that are stuck on the screen 12 and cannot continue to slide down, so that the material stuck on the screen 12 can continue to move.

[0026] The granulation device 3 includes a frame 4, on which a drive motor 2 is installed. The output end of the crushing motor 11 is connected to a grinding disc module 5. A discharge module is connected to the top of the grinding disc module 5. A pressure roller module 6 is provided on the top of the discharge module. A receiving hopper 1 is provided on the top of the pressure roller module 6. A granulation discharge port 7 is provided on the side wall of the discharge module.

[0027] In summary, in actual use, carbon black is pulverized by a pulverizing device to obtain carbon black powder. The carbon black powder material required for granulation is injected into the receiving hopper 1. The powder material falls from the receiving hopper 1 into the granulation device 3. The powder material is granulated in the granulation device 3, and then enters the screening chamber 20 through the granulation outlet 7 and the screening inlet for screening. Particles that are too small fall directly through the screen 12 and are discharged from the waste outlet 17 along the inclined plate 16 to be collected outside the device. Particles that are too large are crushed by the action of the screen 12 and the crushing roller 13. After being crushed, the oversized particles fall from the screen 12 and are discharged from the waste outlet 17 along the inclined plate 16 to be collected outside the device. The collected powder material can be pulverized and mixed and reused for granulation.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
