Centrifugal efficient wood chip granulator

Abstract

The invention provides a centrifugal wood chip granulator which is granule manufacture equipment. The granulator comprises a frame, a die which is statically fixed on the frame, a rotating main shaft connected with a power mechanism and a pinch roller assembly arranged on the rotating main shaft, wherein a pinch roller adjusting device on the pinch roller assembly can ensure that the pinch roller and the inner surface of the die are constantly inscribed. Wood chips and other materials are fed from the upper end of the granulator, thus a static granulating mode of the die is created, and the materials in a compression cavity are ensured to be in a compressed and centrifuged state, so the granulation effect is good; axes of the die and rotating main shaft are superposed and in a vertical state, the die has a unique design, and the treatment efficiency and the treatment effect are improved.

Description

technical field [0001] The invention relates to a pellet manufacturing equipment, in particular to a centrifugal sawdust granulator which utilizes wood chips and other plant fibers to make fuel pellets. Background technique [0002] Renewable biofuels refer to high-density fuel rods or pellets formed by compressing agricultural and forestry wastes such as straw, sawdust, weeds, shrub branches and even fruit shells and peels at room temperature or high temperature. The combustion value of this particle is 4 times higher than the combustion value of the traditional combustion method. It is a high-grade clean energy with a combustion method and calorific value close to coal but basically no pollutant emissions. It is used for urban and rural domestic energy and industrial use. It can provide an environmentally friendly, economical and safe green consumption method, and is a new energy advocated by the state. [0003] Worldwide, the bottleneck of biofuel application is mainly t...

AI Technical Summary

Problems solved by technology

[0006]① Due to the layout of the ring die, the feed port of the ring die granulator must be placed on the side, and a thrust device is required to fill the ring die. Even so, the specific gravity is light It is still difficult for the material to enter the compression chamber;

[0007]②The layout of the ring die causes the compression cavity to not dissipate heat in time, which reduces the service life of the whole machine;

[0008]③ When the ring die rotates, the material in the compression chamber tends to arch, causing uneven feeding, affecting output and compression efficiency; words, resulting in uneven material distribution

[0009]④ The ring die and the pressure roller need to be driven by independent drive motors, which consumes a lot of power and increases the difficulty and cost of manufacturing
