Granulator

Abstract

The invention discloses a granulator which comprises a base, a first motor, a second motor, a feeding device, a feeding pipe, a conveying pipe, a pressing device and a transmission device, wherein the second motor is used for conveying materials to the feeding device from the feeding pipe, then the materials enter the pressing device through the conveying pipe to be pressed; power required by pressing is provided by the first motor, and is transmitted to the pressing device through the transmission device; the pressing device comprises a main shaft, a circular mould, a main shaft pressing plate connected with the main shaft, two roll pressing shafts arranged on the main shaft pressing plate in parallel, and four pressing rolls; and two pressing rolls are arranged on each roll pressing shaft, spacing is set between the two pressing rolls on each roll pressing shaft, six rows of mould holes are formed in the circular mould, and every three adjacent rows of mould holes form one group, and spacing is set between two groups of mould holes. The space between the two groups of mould holes is equal to the spacing between the pressing rolls on each roll pressing shafts. The granulator disclosed by the invention is simple to operate, high in production efficiency, low in energy consumption and long in service life.

Description

technical field [0001] The present invention relates to a granulator. Background technique [0002] In response to the call of the national circular economy, energy conservation and emission reduction, the three agricultural wastes (straw, peanut shells, etc.), wood chips, bamboo chips and other wastes are pressed into biomass particles that can be used for boiler combustion to replace coal, oil and natural gas. Renewable energy not only saves energy, but also is more environmentally friendly. Therefore, there is a need for a machine that compresses the three agricultural wastes into biomass particles, that is, a granulator. At present, although granulators have been common in the market, their output is not high, and they all adopt the structure of a ring die and two pressure rollers. The ring die is full of die holes. The working surface is wide and the friction force is large. During the pressing process, nearly 25% of the electric energy is consumed on the friction bet...

AI Technical Summary

Problems solved by technology

At present, although granulators have been common in the market, their output is not high, and they all adopt the structure of a ring die and two pressure rollers. The ring die is full of die holes. The working surface is wide and the friction force is large. During the pressing process, nearly 25% of the electric energy is consumed on the friction between the pressure roller and the ring die, and the wear of the ring die and the pressure roller is also very large, so the problems of energy consumption and short life has also been accompanied by the granulator
