High-speed biomass crusher and crushing method thereof

Abstract

The invention discloses a high-speed biomass crusher comprising a housing and a blade assembly. The blade assembly is directly driven by a motor or driven through a speed increasing gearbox to perform high speed crushing on biomass at a rotating speed within a range from 1200 to 3000 r / min. The blade assembly comprises an upper blade mechanism and a lower blade mechanism, each of which comprises a rotor mechanism driven by a power mechanism to rotate. A plurality of blade rows parallel to the axis line of the rotor mechanism are evenly and annularly distributed to surround the rotor mechanism. Blades on every two adjacent blade rows are arranged to be staggered with each other. Each blade is movably and rotatably connected to a corresponding blade shaft arranged at the periphery of the rotor mechanism and capable of freely swinging around the blade shaft in the radial direction. The high-speed biomass crusher is simple in structure, low in cost, energy-saving and environment-friendly;the crusher is capable of efficiently and thoroughly crushing the biomass and meeting the demands of the crushed biomass of biomass power plane; during crushing, no material congestion and blockage can be encountered; and the blades can well protect themselves during operation, so that the service life of each blade is greatly prolonged.

Description

technical field [0001] The invention relates to a biomass crusher. Background technique [0002] Biomass crushing in biomass power plants has always been a major problem that plagues people. Most of the existing crushers generally cannot be directly applied to biomass crushing. , The chipper crushes the biomass), the equipment consumes a lot of power, the noise is loud, the working environment is harsh, and the safety of the operators is low. Their crushing mechanism is to use the moving blade and the static blade to shear and crush the biomass. The speed of the rotor is relatively low, generally not higher than 1000r / min, so the output of the crusher is also very low, and the crushed material If it is not thorough (such as typical long strips of easily entangled biomass, it is not easy to break completely), it cannot meet the demand of biomass power plants at all. The structure of these machines is generally composed of a rotor with integral moving blades and a fixed stat...

Problems solved by technology

The blade with such a structure wears faster during work, and the blade is easily damaged if it encounters harder materials (such as wood, bamboo chips, etc.). It is easy to damage the blade, affect the normal operation of the machine, or even get stuck or damaged, forcing production to be stopped and repaired.

Even if there is a design to prevent the blade from being broken when moving, as the toothed roller structure of the double-roller crusher disclosed by the State Intellectual Property Office of China on January 19, 2005, the publication number is 1565744, and the blade can be partially broken when it encounters a hard object. Indented into the dovetail groove, but the actual protection effect of this structure is limited, the blade indentation resistance is relatively large, the structure is relatively complicated, the production cost is high, and the process is cumbersome
