Abstract

The invention relates to processing equipment of crop residual products, in particular to a straw generation dense combustion unit, comprising a power source, a base and two straw extrusion tubes arranged on the base, wherein the straw extrusion tube is internally provided with a lead screw and a nut; two outer ends of the lead screw are provided with straw extrusion pistons; the nut is provided with a main gear which is meshed with a pinion; and the pinion is arranged on a transmission shaft which is connected with the power source through a transmission mechanism. For the combustion unit, the extrusion equipment is installed in the straw extrusion tube, and the nut is used for driving the lead screw, thus realizing the solidifying and extruding of the fuel; the left-right reciprocating motion of the lead screw is realized by using a solenoid directional valve; a pressing device is arranged for tamping the straw in the vertical direction; and the processing equipment has the advantages that the wear is small and the disassembly and maintenance are convenient.

Description

technical field [0001] The invention relates to processing equipment for crop residues, in particular to a compact combustion unit for straw power generation. Background technique [0002] At present, the industrialization of biomass briquette fuel in developed countries in the world is very mature; the application of biomass fuel is also very wide and the consumption is huge. In my country, except for the biomass briquettes produced from crop residues which have a certain scale in the main agricultural production areas, forest biomass briquettes are almost blank. In the late 1980s, some enterprises such as Shaanxi Wugong Light Industry Machinery Factory and Jiangsu Donghai Grain and Oil Machinery Factory produced screw extruders for biomass solidification molding fuel, and the raw materials were mainly rice husk and sawdust. Due to the unqualified material and heat treatment, the screw is severely worn under the action of high pressure and high temperature. Generally, the ...
