Energy-saving and environment-protecting spiral granulator

Abstract

The invention discloses an energy-saving and environment-protecting spiral granulator. The energy-saving and environment-protecting spiral granulator comprises a feeding mechanism, a grading cutting structure, a fine crushing mechanism and a driving mechanism, wherein the feeding mechanism comprises an auger feeder; the grading cutting structure comprises a cutting barrel, partition plates are fixedly arranged in the cutting barrel, and cutting holes are formed in the partition plates correspondingly; a cutter shaft is arranged in the cutting barrel, and a cutter is arranged on the cutter shaft; the fine crushing mechanism comprises a film pressing cover, the cutting barrel communicates with the film pressing cover, a main shaft is arranged in the film pressing cover, the main shaft is driven by the driving mechanism to rotate, and the main shaft drives the cutter shaft to rotate; a negative pressure discharging opening is formed in the lower end of the cutting barrel, and the negative pressure discharging opening is connected with a negative pressure conveying device; and the interior of the film pressing cover communicates with the negative pressure discharging opening, a plurality of cutting knives are arranged in the film pressing cover, and the cutting knives are fixed on the main shaft. The energy-saving and environment-protecting spiral granulator is used for granulating in a low-temperature environment, so that the environment is prevented from being polluted by smoke and the health of operators is prevented from being influenced, and meanwhile, the energy consumption can be reduced.

Description

technical field [0001] The invention belongs to the technical field of granulators, and in particular relates to an energy-saving and environment-friendly spiral granulator. Background technique [0002] In the preparation process of wood-plastic materials, it is necessary to use a granulator to cut and modify plastic particles. The existing granulator needs to heat the plastic granules to a high temperature of more than 200 degrees during the granulation process, and cooperate with the cutter to cut and granulate. Plastic particles at high temperature will produce a large amount of smoke, which seriously endangers the health of workers and pollutes the environment. At the same time, the softened plastic particles form viscous resistance to the operation of the cutter, which increases the load on the motor. It is necessary to match a high-power motor to meet the production capacity demand. Contents of the invention [0003] In order to solve the above-mentioned technical...

Problems solved by technology

Plastic particles at high temperature will produce a lot of smoke, which seriously endangers the health of workers and pollutes the environment

At the same time, the softened plastic particles form viscous resistance to the operation of the cutter, which increases the load on the motor. It is necessary to match a high-power motor to meet the production capacity requirements.
