Biomass granular fuel crushing device with material pressing function

Abstract

The invention discloses a biomass granular fuel crushing device with a material pressing function. The device comprises a crushing device; the crushing device comprises a first crushing chamber and asecond crushing chamber; a crushing motor is mounted at the bottom of the second crushing chamber; the output shaft of the crushing motor is connected with a first rotating shaft through a coupling; hammer plate frames are correspondingly arranged outside the first rotating shaft; the two hammer plate frames are respectively positioned in the first crushing chamber and the second crushing chamber;crushing parts are uniformly arranged on the hammer plate frames; a middle screen is arranged between the first crushing chamber and the second crushing chamber; a feeding hole is formed in the top of the first crushing chamber; the crushing parts are an L-shaped blades; the corners of the tail ends of the L-shaped blades are obtuse angles; the first rotating shaft is sleeved with a rotating scraping piece; the rotating scraping piece is located at the top of the middle screen; and the rotating scraping piece is in the shape of a fan blade. With the device of the invention adopted, material deposition can be avoided, and high working efficiency can be realized.

Description

technical field [0001] The invention relates to the technical field of biomass particle fuel crushing, in particular to a biomass particle fuel crushing device with a pressing function. Background technique [0002] Biomass fuel is a block-shaped environmentally friendly new energy produced by processing straw, straw, rice husk, peanut husk, corncob, camellia husk, cottonseed husk, etc., as well as "three leftovers". Due to the low density of biomass fuel, it is not easy to store, handle and transport, so there are processing equipment on the market to process it into bio-pellet fuel. [0003] In the existing crushing device, when the material just enters the crushing chamber, the relative speed difference between the material and the crushing part is relatively large, and the impact force of the crushing part is great, and then the rotating crushing part drives the material to move with it at a high speed, and the striking efficiency of the crushing part decreases ; The ex...

Problems solved by technology

[0003] In the existing crushing device, when the material just enters the crushing chamber, the relative speed difference between the material and the crushing part is relatively large, and the impact force of the crushing part is great, and then the rotating crushing part drives the material to move with it at a high speed, and the striking efficiency of the crushing part decreases ; The existing crushing equipment generally deposits the crushed materials on the bottom screen below by gravity, which hinders the fine particle materials from passing through the screen and increases the resistance of the rotor; the existing crushing device can only crush the raw materials, Then compressed into large pieces for transportation, and then need to be decomposed into small pieces when transported to farmers’ homes, which is time-consuming and laborious and insufficient combustion
