Description

Technical Field

[0001] This utility model relates to the field of waste rubber recycling technology, specifically to a pyrolysis carbon black granulation device for waste rubber recycling. Background Technology

[0002] Waste rubber is a waste resource with recyclable value. Recycling waste rubber not only improves resource utilization efficiency but also reduces its environmental pollution. Waste rubber is often decomposed into powdered rubber pyrolysis carbon black during recycling. However, since rubber pyrolysis carbon black is lightweight, it is not conducive to transportation and subsequent processing. To reduce transportation costs and protect the environment, it is important to process the powdered carbon black into granules for its subsequent use. Therefore, a pyrolysis carbon black granulation device for waste rubber recycling is needed.

[0003] The prior art discloses a waste rubber pyrolysis carbon black granulation device with publication number CN202221820883.7. In the above-mentioned utility model, the pyrolysis carbon black powder is introduced into the inner cavity of the granulator cylinder through the feeding box, and then an appropriate amount of water is added for mixing. Finally, the granulation operation is achieved by rotating the electric rotary blade through the drive motor and coupling. However, the feeding box is difficult to fully and evenly mix the pyrolysis carbon black powder and water, thus affecting the quality of subsequent granulation processing. Adding a stirring motor to pre-stir the raw materials will significantly increase the production cost of the equipment, making its practicality relatively limited. In view of the shortcomings of this utility model, those skilled in the art have proposed a waste rubber recycling pyrolysis carbon black granulation device. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a pyrolysis carbon black granulation device for waste rubber recycling, which has the following beneficial effects:

[0016] (1) This utility model is equipped with a granulation cylinder and a feeding box. A granulation shaft is installed in the center of the inner cavity of the granulation cylinder, and rotating blades are evenly fixedly installed on the granulation shaft. A stirring shaft is installed in the center of the inner cavity of the feeding box, and several stirring blades are evenly fixedly installed on the stirring shaft. A motor base is fixedly installed on one side of the granulation cylinder, and a servo motor is installed on the motor base. A coupling is connected to the output end of the servo motor.

A first bevel gear is fixedly installed on one end of the granulation shaft, and a second bevel gear is fixedly installed on the bottom end of the stirring shaft. The second bevel gear meshes with the first bevel gear. In use, the rubber pyrolysis carbon black powder is fed through the feeding hopper. The material is introduced into the inner cavity of the feeding box, and then an appropriate amount of water is introduced into the feeding box through the liquid inlet pipe. Then, the servo motor is started through the control panel to drive the granulation shaft to rotate, which in turn drives the stirring shaft to rotate. The stirring shaft drives the stirring blades to rotate, which can achieve a thorough and uniform mixing of pyrolysis carbon black powder and water, which is beneficial to improving the subsequent granulation effect. The well mixed pyrolysis carbon black material is introduced into the inner cavity of the granulation cylinder through the feeding pipe. The rotating blades squeeze and push the material, and finally the material is extruded through the extrusion disc for granulation. This utility model can achieve a thorough and uniform mixing of pyrolysis carbon black powder and water without adding an additional stirring motor, which is beneficial to improving the granulation effect and has greater practicality.

[0017] (2) This utility model is equipped with a storage box, a vibrating mounting frame, a sieve frame, and a discharge box. The storage box is fixedly installed at one end of the granulation cylinder, and a fixing block is fixedly installed on the inner wall of the storage box. A telescopic rod is installed on the fixing block. The movable end of the telescopic rod is connected to the vibrating mounting frame, and a vibration spring is sleeved on the outside of the telescopic rod. In use, the sieve frame can be placed on the vibrating mounting frame, and the discharge box can be placed directly below the sieve frame. As described above, the extruded material is granulated through the extrusion disc. Pelletizers are symmetrically fixedly installed on the granulation shaft to perform pelletizing operations on the extruded material. The resulting granular material falls into the inner cavity of the screening frame. On the other hand, an eccentric wheel is fixedly installed at one end of the granulation shaft inside the storage box. When the eccentric wheel rotates, it continuously strikes the vibrating mounting frame, thereby cooperating with the vibration spring to drive the screening frame to vibrate. The screened material falls into the inner cavity of the discharge box and can be taken out through the discharge port. This process separates larger and smaller granules, avoiding the impact of larger rubber particles on the performance during subsequent use. No additional vibration motor is required in this process, which helps reduce the manufacturing cost of the equipment and makes it more practical. Attached Figure Description

Then, the servo motor 3 is started through the control panel 21 to drive the granulation shaft 15 to rotate, which in turn drives the stirring shaft 5 to rotate. The stirring shaft 5 drives the stirring blades 8 to rotate, which can achieve a thorough and uniform mixing of the pyrolytic carbon black powder and the water, which is beneficial to improving the subsequent granulation effect. The mixed pyrolytic carbon black material is introduced into the inner cavity of the granulation cylinder 1 through the feed pipe 16.

On the other hand, an eccentric wheel 10 is fixedly installed at one end of the pelletizing shaft 15 located in the inner cavity of the storage box 9. When the eccentric wheel 10 rotates, it continuously strikes the vibrating mounting frame 20, thereby cooperating with the vibration spring 27 to drive the screening frame 11 to vibrate.
