Embodiment Construction

[0027] As shown in FIGS. 1 to 3 , the present invention is a vertical installation or a horizontal installation, and its cylinder includes a bottom surface, a top surface and a side wall, which can be cylindrical, and the cylinder is divided into a first half cylinder 2 and a cylinder along the axial direction. The second half cylinder 8 is fixed with the flange 7, the main shaft 3 is axially installed in the center of the cylinder, and the multi-layer cutter 5 is installed along the main shaft in the direction perpendicular to the main shaft 3. The cutter 5 is connected to the wall of the cylinder. There is a gap between them, the cutter 5 is composed of straight-edged blades 10, a multi-layer annular plate 4 is installed on the wall of the cylinder, a plurality of holes 9 are opened on the annular plate 4, and between the annular plate 4 and the main shaft 3. There is a gap between the two layers of cutters 5, between the two layers of annular plates 4 or between the cutters ...

Abstract

The biomass crusher has the structure comprising one barrel with material inlet and material outlet and divided axially into two parts fixed with flanges, one main shaft mounted in the axial center of the barrel, several layers of cutting knifes mounted perpendicularly to the main shaft; and several layers of ring plates with holes mounted on the barrel wall. There are gap between the cutting knifes and the barrel wall, gap between the ring plates and the main shaft, gap between two layers of ring plates and gap between the cutting knifes and the ring plates. The present invention has compact structure, small crushed product size, low power consumption, high production efficiency and convenient maintenance.

Description

technical field [0001] The invention relates to a crusher, which is mainly suitable for the crushing of biomass, especially for the agricultural and forestry wastes after rough crushing, such as straws, branches, leaves, waste wood and the like. Background technique [0002] With the increasing depletion of petrochemical energy and the increasingly serious harm to the environment caused by its combustion, biomass energy has increasingly attracted worldwide attention due to its renewability and cleanliness. The development of raw materials can not only make rational use of agricultural and forestry wastes (such as straw, branches, leaves, waste furniture, etc.), prevent energy waste, increase economic benefits, but also reduce CO 2 , SOx, NO X and soot and other emissions, alleviating environmental pollution. [0003] Biomass energy has a wide range of sources, low prices and no environmental pollution, but it has not been widely used. The main reason is that the current co...
