High-efficiency heating mixer and mixing method for plastics processing industry

Abstract

The invention discloses a high-efficiency heating mixer for the plastics processing industry and belongs to the technical field of plastics processing. A discharging outlet is formed in the right sideof the bottom of a crushing box, a tubular auger is arranged on the side wall of the outer edge of a second rotating shaft, and a fixed connecting frame is arranged at the top of the inner cavity ofa mixing box. A heating metal bar is arranged on the side, away from a connecting hoop, of a heat-resistant pad, and heat sinks are uniformly arranged on the side wall of the outer edge of the heatingmetal bar in the circumferential direction. A warm air box is arranged on side wall of the inner cavity of the mixing box, and spoilers are uniformly arranged on one the side, away from the mixing box, of the warm air box in the circumferential direction. A fan heater is arranged at the top of a material placing plate, and the right side of the fan heater is connected with the mixing box througha ventilation pipe. The high-efficiency heating mixer for the plastics processing industry is reasonable in structure design and easy to use, uneven heating of mixed material is avoided, so that the heating effect of the mixed material is improved, the purpose of preheating raw materials is achieved, and at the same time, the efficiency of mixing material and the production effect can be improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-efficiency thermal mixer and a material mixing method used in the plastic processing industry. Background technique [0002] Thermomixer is one of the essential equipment in plastic processing industry. It is mainly used for uniform mixing of various resins such as polyvinyl chloride and other auxiliary materials and achieving the purpose of process temperature in a short time. It is also suitable for coloring and mixing of polyethylene, polypropylene and other pellets and drying before warm resin products. The mixing process is not only a physical process, but also a complex chemical process. The high-speed impact, shearing, throwing, and self-friction of the blades in the thermomixer make it reach the specified end point temperature according to the set temperature gradient requirements. , and complete the requirements of homogenization, macromoleculeization ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structural design of the stirring blades is unreasonable, resulting in slow material friction heat generation, resulting in poor production efficiency; and the lack of external auxiliary heat during mixing will also lead to poor results; in addition, in the rotating shaft In the process of driving the blades to work, the shell will generate a large vibration, which will affect the processing effect of the material
