Novel three-press-roll speed-variable granulation machine

Abstract

The invention discloses a novel three-press-roll speed-variable granulation machine which comprises a granulation device and a driving device for supplying power to the granulation device, wherein the granulation device comprises a shell and an annular mould arranged in the shell; three press rolls are arranged in the annular mould; the press rolls are driven to rotate through a rotating shaft by the driving device; the axial direction of the annular mould is vertically arranged; and the axial direction of the press rolls, the axial direction of the annular mould and the axial direction of the rotating shaft are parallel to each other. According to the novel three-press-roll speed-variable granulation machine, three press rolls are arranged in the annular mould, the three press rolls are symmetrically arranged, the pressure is offset with each other, the abrasion is reduced, the uniform stress endured by the device is ensured, the device is difficult to be damaged, the materials are thoroughly extruded, no dead angle is leaved and the production efficiency is increased; the driving device is horizontally arranged through a bevel gear; a multi-level gearbox is used, so that the suitable extruding speed can be selected according to the raw materials; the transmission speed is changed while the torsion is increased; and the effect of driving a big device through a small motor is achieved.

Description

Technical field [0001] The invention relates to a granulator, in particular to a novel three-roller variable-speed granulator. Background technique [0002] Biomass energy is an important part of new energy and has important characteristics such as pollution-free and renewable. This is very different from the use of high-energy and high-pollution primary energy sources such as petroleum and coal. Increasing the utilization of biomass energy can effectively reduce carbon dioxide emissions and reduce environmental pollution. Secondly, biomass energy has a wide range of sources and is convenient to use. Rural crop straw provides an important source for biomass energy utilization. For example, a large amount of straw is produced in various parts of North China, Northeast China, and China. Incineration will cause air pollution, and landfill will also pollute. Soil, this has become a huge local social problem. The production of biomass pellet fuel can solve this problem well and brin...

Problems solved by technology

[0005] In addition, the power system of the granulator in the prior art cannot realize multi-stage variable speed, so the appropriate extrusion speed cannot be adjusted according to the raw material, which may easily cause the breakage of the pressure wheel shaft and affect the service life of the equipment
