[0002] The production of regenerated plastic particles plays an important role in modern manufacturing industry. With the increasing awareness of environmental protection and the increasing demand for resource recycling, the production scale of regenerated plastic particles is expanding. It not only effectively reduces the pollution of plastic waste to the environment, but also reduces the dependence on virgin plastic, saves resources and energy. However, there are some problems in the production process of regenerated plastic particles, one of which is the high noise generated in the conveying process. Traditional pipelines for conveying regenerated plastic particles often lack effective noise reduction measures. In the conveying process of plastic particles, a large amount of noise will be generated due to the collision, friction between particles and the impact of particles on the inner wall of the pipeline. These noises not only cause physical harm to the operators in the production workshop, such as hearing loss, tinnitus, headache, etc. caused by long-term exposure to high noise environment, but also affect the psychological state of workers and reduce work efficiency. At the same time, high noise environment does not meet the requirements of environmental protection and labor protection, which has a negative impact on the sustainable development of enterprises.

However, this conveying pipeline lacks effective noise reduction measures. In the conveying process of plastic particles, a large amount of noise will be generated due to the collision, friction between particles and the impact of particles on the inner wall of the pipeline. These noises not only cause physical harm to the operators in the production workshop, but also affect the psychological state of workers and reduce work efficiency, so a regenerated plastic particle production workshop conveying pipeline noise reduction device is needed.

Enhance the noise reduction performance: the cooperation of shock-absorbing convex layer 8 and buffer guide vane 6 can more effectively reduce the noise in the material conveying process, improve the noise reduction effect of the noise reduction device;The setting of buffer guide vane 6 can make the flow of materials in the pipeline more orderly, reduce the vortex and disturbance of materials, not only reduce the noise, but also help to protect the inner wall of the pipeline, prolong the service life of the pipeline.

[0024] In this embodiment, the shock-absorbing protrusion layer 8 is composed of a plurality of shock-absorbing protrusions 9, and the material of the shock-absorbing protrusions 9 is polyurethane.

[0025] In this embodiment, the double-layer hollow porous structure 10 is composed of a plurality of annular grooves 11, and the material of the double-layer hollow porous structure 10 is polytetrafluoroethylene. The double-layer hollow porous structure 10 composed of a plurality of annular grooves 11 can more effectively absorb and disperse the noise generated during the material conveying process, further improving the noise reduction effect.
