Problems solved by technology

Since the biomass raw material is a non-brittle material, the existing milling equipment tends to generate fiber clusters during the milling process, which makes the milling efficiency low, and the biomass raw material needs to be dried to a high degree, which increases the cost of milling

Abstract

The invention provides a biomass raw material milling device, and relates to the early-stage processing technology of biomass fuel. The biomass raw material milling device comprises a speed reduction motor, a milling machine tool and a machine base. The speed reduction motor and the milling machine tool are installed on the machine base. The milling machine tool is mainly composed of a milling core and a milling cavity shell. The front half portion of the milling core is of a circular truncated cone structure, and the rear half portion of the milling core is of a cylinder structure. A milling rough surface is arranged on the outer surface of the milling core. A spiral shearing groove is distributed in the outer side of the wall body of the milling core. The circular truncated cone structure of the front half portion of the milling core extends into a fine milling cavity in the milling cavity shell. The cylinder structure of the rear half portion of the milling core is arranged in a rough milling cavity in the milling cavity shell. A discharge port is formed by an opening in the front end of the milling cavity shell. By means of the biomass raw material milling device, biomass raw materials are subjected to two times of milling in the rough milling cavity and the fine milling cavity in sequence, and milled powder can be fine and uniform; and the spiral shearing groove, a spiral cutting groove and a milling straight groove are in dynamic and static fit, the shearing effect is formed, it is avoided that fiber agglomerates are generated so that milling can be unceasingly conducted, and the milling efficiency is improved.

Description

technical field [0001] The invention relates to the pretreatment technology of biomass fuel, in particular to biomass pulverizing equipment. Background technique [0002] Biomass is a kind of renewable energy. Biomass can absorb carbon dioxide during the growth process and store solar energy through photosynthesis. Biomass fuel produces almost no pollution when burned, and almost no sulfur dioxide is produced. It is a carbon dioxide-neutral fuel. Replacing fossil fuels with biomass fuels has great benefits in reducing the greenhouse effect, and the environmental protection and ecological effects are outstanding. [0003] my country is very rich in biomass resources. The annual output of non-wood fibers such as crop stalks, reeds, and bamboo exceeds 1 billion tons, plus a large amount of wood processing residues, which are huge energy "warehouses". However, the waste of agricultural and forestry surplus materials in our country is astonishing. Except for a small part of rura...
