AI Technical Summary

Technical Problem

Traditional mixing devices cannot effectively scoop up the material deposited at the bottom of the mixing tank, resulting in dead zones in the mixing process. This leads to uneven mixing of the flame-retardant polyethylene raw materials, affecting the flame-retardant efficiency and mechanical properties of the product.

Method used

The system employs a combination of three mixing methods: shovel head, spiral belt, and bulk material device. Combined with the external meshing of conical helical gears and conical helical gear rings, it achieves complete material circulation and deep dispersion without dead zones, ensuring uniform mixing of raw materials.

Benefits of technology

The mixing uniformity of flame-retardant polyethylene raw materials was improved, enhancing the flame-retardant efficiency and mechanical properties of the product, thus meeting the requirements of high-end interior materials.

Abstract

This utility model relates to the field of mixing devices, and discloses a mixing device for flame-retardant polyethylene raw materials used in automotive interior production. The device includes a mixing chamber, where a reducer drives a mixing device inside the mixing chamber to rotate. The mixing device includes a central shaft and mixing shafts. The central shaft is horizontally located at the center of the mixing chamber, and its left end is fixed to the output end of the reducer via a coupling. Two sets of mixing shafts are symmetrically fixed to the central shaft. Each set of mixing shafts includes a shovel shaft, a pusher shaft, and a dispersing shaft. A shovel head is fixed to the outer end of the shovel shaft. A spiral belt is fixed to the outer end of the pusher shafts of both sets of mixing shafts. A dispersing device is installed on the dispersing shaft. This utility model combines three mixing methods—shovel head, spiral belt, and dispersing device—to achieve a mixing effect that is thorough, fully circulating, and deeply dispersed, ensuring uniform mixing and consistent performance of the raw materials. The mixing uniformity is significantly improved compared to traditional mixing devices.
