Description

Technical Field

[0001] The utility model relates to the technical field of rubber regeneration processing devices, in particular to a positive pressure pneumatic dispersion and pushing device for regenerated rubber powder. Background Art

[0002] In the field of rubber recycling and reuse, the regeneration of rubber powder has always been a hot topic of research. Traditional methods of rubber powder regeneration mostly rely on chemical or mechanical means, which not only have high energy consumption and low efficiency, but also may cause secondary pollution and have adverse effects on the environment. In recent years, with the improvement of environmental awareness and the development of pneumatic technology, pneumatic dispersion and pushing technology has gradually attracted people's attention and demonstrated its unique advantages in many fields.

[0003] Pneumatic dispersion and pushing technology is a new type of conveying technology that disperses and pushes materials in pipelines through the action of positive pressure airflow. This technology has the advantages of low energy consumption, little damage to materials, and no pollution. In the field of rubber powder regeneration, the use of pneumatic dispersion and pushing technology for rubber powder regeneration can not only improve processing efficiency and reduce energy consumption, but also effectively reduce the impact on the environment.

[0004] When the recycled rubber powder positive pressure pneumatic dispersion and pushing device on the market is used, it generally uses the air source to pass into the pipeline to achieve the rubber powder dispersion and pushing outward. However, when the air source is passed into the pipeline for transportation, since the two ends of the material transportation pipeline are respectively connected to the material end and the external output end, at this time, after the air source enters, there is a situation where the material is blown back to the material end, so that the material cannot be normally dispersed and pushed outward, affecting the normal outward dispersion and pushing effect of the material. In view of this, we propose a positive pressure pneumatic dispersion and pushing device for recycled rubber powder. Utility Model Content
