Centrifugal efficient wood chip granulator

Abstract

The invention provides a centrifugal efficient 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 particle manufacturing equipment, in particular to a centrifugal high-efficiency sawdust granulator which utilizes wood chips and other plant fibers to make fuel particles. 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 app...

AI Technical Summary

Problems solved by technology

[0006] ①Due to the layout of the ring die, the feed port of the ring die granulator must be placed on the side, and a forced thrust device is required to fill the ring die. Even so, it is still difficult for materials with light specific gravity 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] ③When the ring die rotates, the material in the compression chamber is prone to arching, resulting in uneven feeding, which affects the output and compression efficiency; at the same time, the ring die rotates, and the material has no centrifugal force at all, resulting in uneven distribution of the material

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