Description

Technical Field

[0001] The utility model relates to the technical field of resin production, in particular to a resin particle collecting device used in resin production. Background Art

[0002] Resin particles are usually waste and by-products generated during the plastic processing process. During the production process, plastic sheets are melt processed, extruded or injected to form solid resin particles. These particles may differ in size, shape or color, but they all have high plasticity and reuse value. Generally speaking, factories will recycle and reuse resin particles in the production process to reduce waste and save costs. The method of collecting resin particles may vary depending on the process, equipment and materials, but it is usually carried out by screening, absorption, centrifugation, filtration or electrostatic adsorption. Among them, filtration is a simple cleaning of the attachments on the surface of the resin, and after cleaning, the water on the surface is filtered and dried.

[0003] Traditional resin particle collection involves soaking, bleaching and mixing the plastic. Mixing requires a stirring rod, and then a filter is added to filter the water. Finally, the drying component is used for drying. This internal component requires multiple partition functions to cooperate, and the structure is complex. One component cannot be used for multiple functions, which reduces the internal structure.

[0004] The existing Chinese patent with announcement number CN220075230U discloses a resin particle collection device for resin production, which belongs to the field of resin particle technology; it includes a base 1, a support frame 2, a dryer, and a collection box 3. A collection component is arranged inside the collection box 3 and the collection component includes a filter box 6, a rotating rod 1 601, and a rotating rod 2 602. Limiting grooves 4 are respectively arranged on opposite sides of the inner wall of the collection box 3.

The top of the collection box 3 is fixedly connected to a drying main pipe 7 and the lower end of the drying main pipe 7 is fixedly connected to a plurality of branch pipes 701 extending to the inside of the collection box 3.

[0005] In view of the above and existing related technologies, the inventors believe that the following defects often exist: after the device is dried, the particles are dispersed and are not easy to be discharged from the discharge port, which needs to be improved; therefore, a resin particle collection device for resin production is proposed to address the above problems.
