Biomass straw granulator

Abstract

The invention relates to a biomass straw granulator. As for the biomass straw granulator, a main shaft assembly mainly comprises a main shaft, a large chain wheel and a flange; a press roll assembly mainly comprises a pressure head, a press roll shaft, a roller bearing and a press roll; the main shaft, the pressure head and the press roll shaft are all of a hollow structure; the central cavities of the main shaft, the pressure head and the press roll shaft are mutually communicated; a water internal circulation cooling system is formed by arranging an inlet pipe and a cooling pipe in each cavity; and under the action of water pressure, cooling water reflows in the gap between the central cavity of the press roll shaft and the cooling pipe, then reflows to the upper opening of a plug through the gap between the central cavity of the main shaft and the inlet pipe, and flows to a water tank from a reflowing hole of the plug to complete the internal circulation process. According to the biomass straw granulator disclosed in the invention, the machine performance is improved, the reliability, stability and service life of the machine can be enhanced, the output is increased and the energy consumption is reduced.

Description

technical field [0001] The invention relates to energy-saving and environment-friendly equipment, in particular to a biomass straw granulator. Background technique [0002] At present, straw pellets are a new type of renewable resource, with a wide range of applications mainly including four fields: feed, energy, fertilizer and industrial raw materials. Biomass straw granulator is a kind of machinery that crushes agricultural and forestry wastes through processes such as crushing, drying, and molding, and densifies dispersed low-density energy resources into high-density new fuels through the biomass straw granulator. Existing products of the same type adopt a single pressure roller structure, the specifications of the flat die used are fixed, and the cooling method of the pressure roller bearing is grease heat dissipation; due to the relatively backward structural design, the usual problems include: Low output and high power consumption.

AI Technical Summary

Problems solved by technology

Existing products of the same type adopt a single pressure roller structure, the specifications of the flat die used are fixed, and the cooling method of the pressure roller bearing is grease heat dissipation; due to the relatively backward structural design, the usual problems include: Low output, high power consumption

Flat molds of different specifications cannot be replaced, and the same machine has a single variety, and can only produce one specification of straw pellet products

Roller bearings rely on grease to dissipate heat, and the overheating of roller bearings not only consumes a lot of grease, but also easily causes bearing damage, forcing the machine to stop for cooling, and the machine cannot run continuously, which greatly reduces production efficiency.

The die hole is easy to block and cause the motor to overheat
