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

The invention discloses an elastic pressing type biomass grinding device and relates to a technology for earlier-stage treatment of biomass fuel. The elastic pressing type biomass grinding device is mainly composed of a grinding head and a grinding cavity shell. The outer surface of the grinding head is provided with a rough grinding face, and spiral shearing grooves are distributed in the outer side of the wall of the grinding head. A spring chamber, a rough grinding cavity and a fine grinding cavity are formed in the grinding cavity shell. A discharging port is formed by an opening in the front end of the grinding cavity shell. The spring chamber and the rough grinding chamber are of a cylinder space structure, and the fine grinding cavity is of a cone frustum space structure. Straight grinding grooves are horizontally distributed in the inner wall of the rough grinding cavity. Spiral shearing grooves are distributed in the inner wall of the fine grinding cavity. The grinding head is arranged in the inner space of the grinding cavity shell. A supporting plate is installed at the rear end of the grinding cavity shell. A jacking pressing spring is arranged between the rear end of the grinding head and the supporting plate in a jacking pressing manner. According to the elastic pressing type biomass grinding device, the grinding head can have an elastic pressing grinding function, a grinding gap is automatically adjusted, and the grinding head is prevented from being clamped; and the situation that fiber agglomerates are generated, and grinding is conducted continuously is avoided, the grinding efficiency is improved, the requirement for drying biomass raw materials is lowered, and the drying cost of the biomass raw materials is reduced.
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...
