Granulator

Abstract

The invention discloses a granulator comprising a base, a first motor, a second motor, a feeding device, a supply pipe, a feed pipe, a pressing device and a transmission device. The second motor conveys materials from the supply pipe to the feeding device, and then the materials enters the pressing device to be pressed through the feed pipe; power required by pressing is provided by the first motor and transmitted to the pressing device through the transmission device; the pressing device comprises a main shaft, a circular mould, a main shaft pressure plate connected with the main shaft, two press roller shafts which are arranged in parallel on the main shaft pressing plate, and four press rollers; each press roller shaft is provided with two press rollers, and a distance is left between the two press rollers on each press roller shaft; and six rows of mould holes are formed in the circular mould, every three adjacent rows of mould holes are in one group, and a distance is left between each two groups of mould holes and is equal to that between the two press rollers on each press roller shaft. The granulator is simple to operate, and has the advantages of high production efficiency, low energy consumption and long 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...

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
