Description

Technical Field

[0001] The utility model relates to the technical field of polyester bottle chip dehydration, and more specifically, to a dehydration device for recycled polyester bottle chips. Background Technique

[0002] Polyester bottle chips refer to materials obtained by processing and crushing waste polyester plastic bottles into flakes or fragments, and recycled polyester bottle chips refer to recycled PET bottle chips produced by recycling waste polyester plastic bottles.

[0003] The dehydration device for recycled polyester bottle chips is a device used for dehydrating the recycled polyester bottle chips recovered from waste PET bottles during the production of recycled PET. The dehydration device generally includes parts such as a feeding system, a dehydration device, a drainage system, and a control system.

[0004] Existing dehydration devices usually adopt centrifugal dehydration technology, that is, removing the water in the polyester bottle chips through a high-speed rotating centrifuge to improve the drying degree and quality of the recycled polyester bottle chips. However, during the use process, the polyester bottle chips often gather in the mesh drum during centrifugation, thus blocking the intervals on the inner wall of the mesh drum, resulting in poor drainage, which undoubtedly affects the dehydration efficiency of the polyester bottle chips;

[0005] Moreover, the existing dehydration devices for recycled polyester bottle chips only dehydrate by centrifugal separation, and there will often be a certain amount of water stains adhering to the outer wall of the polyester bottle chips. The existing methods usually require adding a certain drying process, and the drying devices inside the existing dehydration devices often cause uneven drying due to the large accumulation of polyester bottle chips, which not only reduces the drying efficiency of the polyester bottle chips but also affects the drying effect, causing many troubles in actual use.

[0006] In view of this, we propose a dehydration device for recycled polyester bottle chips. Content of the Utility Model

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows: when dehydrating polyester bottle chips, the polyester bottle chips can be poured into the separation and dehydration barrel through the feeding hopper, and then the rotating motor two is started to drive the separation and dehydration barrel to rotate at a high speed. Under the action of the rotational centrifugal force, the polyester bottle chips can be centrifugally dehydrated and separated. During the rotation of the separation and dehydration barrel, the rubber knocking blocks inside its multiple support rods will compress and rebound back and forth due to the action of the springs. Whenever the rubber knocking blocks pass through the multiple grooves on the outer wall of the separation and dehydration barrel, the rubber knocking blocks will be driven by the spring rebound to vibrate against the outer wall of the separation and dehydration barrel, thereby reducing the risk of blockage of the separation and dehydration barrel and improving the stability of centrifugal dehydration;
