Straw dehydration extrusion forming machine

Abstract

A straw dehydration extrusion forming machine is used for dehydrating and processing smashed straw into block materials, and is provided with a machine frame; an auger and a material pressing pipelineare installed on the machine frame; the material pressing pipeline is composed of a material pipe and a conical pipe, the material pipe is provided with a feeding inlet, one end of the material pipeis a blind end, the opening of the other end of the material pipe is connected with a flaring flange of the conical pipe, the narrow opening end of the conical pipe is a discharging outlet, and the pipe wall of the conical pipe is provided with a plurality of gas-liquid discharging holes; and the auger is provided with a main shaft, one end of the main shaft is rotationally connected to the machine frame, the other end of the main shaft is arranged in the material pressing pipeline, a shaft body of the main shaft is fixedly connected with a spiral rib sheet, and the axis of the main shaft coincides with that of the conical pipe. The straw block materials which are high in density, small in size and low in water content can be obtained by processing the smashed straw through the straw dehydration extrusion forming machine and can be directly used as fuel for a power plant, storing and transporting are facilitated, and the recycling cost of the straw is reduced.

Description

technical field [0001] The invention provides a straw dehydration extrusion molding machine. Background technique [0002] Straw is the agricultural waste after harvesting corn. In the past, straw was incinerated to pollute the environment. In recent years, straw has been used as fuel for power plants. However, due to the high water content of straw when it is just harvested, the water content is 40-60%. The wet one reaches about 70%, so the straw in the field should be packed into bundles, and then transported to the drying site for drying. Due to the low density of the straw, the packed volume is large and the water content is large, resulting in high transportation costs and raw materials. The pretreatment directly increases the processing cost of straw, so in many places, the straw is still crushed and returned to the field, resulting in a waste of resources. Contents of the invention [0003] The purpose of the present invention is to provide a straw dehydration extr...
