Combined cyclone grinding cutter head assembly and plastic grinding machine

Abstract

The invention discloses a combined cyclone grinding cutter head assembly and a plastic grinding machine, and belongs to the field of grinding machinery. The combined cyclone grinding cutter head assembly comprises an inner cutter head, an outer cutter head and a suction impeller, the outer cutter head is provided with a conical grinding inner wall, the inner cutter head is provided with a plurality of inner blades matched with the conical grinding inner wall, the inner cutter head and the outer cutter head rotate coaxially, and the rotating directions of the inner cutter head and the outer cutter head are opposite; the suction impeller is coaxially fixed to the rear side of the outer cutter head, the rear side of the conical grinding inner wall communicates with the middle of the suction impeller, and the suction impeller and the outer cutter head rotate together to achieve the suction effect from the center to the periphery. According to the pulverizer, the pulverizing efficiency is greatly improved, materials are pulverized more densely, meanwhile, active suction of the materials is achieved through the suction impeller, the flowing speed of the materials is increased, the feeding and discharging speed of the pulverizer is increased, the pulverizing efficiency of the pulverizer is improved, the energy consumption of the pulverizer is reduced, and more energy is saved during operation of the pulverizer.

Description

technical field [0001] The invention relates to a grinding machine and its accessories, more specifically, to a combined cyclone grinding cutter head assembly and a plastic grinding machine. Background technique [0002] With the widespread use of plastic products, the harm of waste plastics to the environment and human health has become a serious problem that people have to face. Plastic recycling technology has also become the main technical means to reduce the harm of waste plastics. At present, most plastics need to be pulverized and pulverized in the recycling process, that is, waste plastics are first broken into small pieces, and then the broken small pieces of plastic are pulverized into powder to realize plastic recycling. [0003] The pulverizer is the main equipment for crushing small pieces of plastic into powdery particles. It uses the internal high-speed rotating cutter head to crush the material. It can also be used for crushing and recycling some other compos...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages of low milling efficiency, high milling energy consumption, and single function of the cutter head of the existing milling machine, and provide a combined cyclone milling cutter head assembly and plastic milling machine. The machine adopts the technical solution of the present invention, uses the inner cutter head and the outer cutter head to rotate in opposite directions to increase the relative speed of the inner and outer cutter heads, and uses the outer peripheral conical grinding design to make the material be quickly ground to form fine powder, greatly The grinding efficiency is improved, and the material is crushed more finely. At the same time, the active suction of the material is realized by using the suction impeller that rotates with the outer cutter head, which accelerates the flow speed of the material and improves the feeding and discharging speed of the mill. The milling efficiency of the mill is improved, and the energy consumption of the mill is reduced, making the operation of the mill more energy-saving.
