Straw compression molding equipment

Abstract

The invention provides novel straw compression forming equipment, and relates to a compression forming device of fiber materials. The novel straw compression forming equipment comprises a main driving mechanism, a precompression mechanism and a compression mechanism. The precompression mechanism comprises a second motor, a feeding box, a precompression packing auger and a forced feeding turnover plate, a reinforcing compression cavity is formed in the outlet end of a compression cavity, and is of a left-and-right buckling structure, the two sides of the reinforcing compression cavity are connected with connecting rod mechanisms respectively, the connecting rod mechanisms are connected with a hydraulic station, the hydraulic station is controlled by an electric drive travel switch, and the hydraulic station and the electric drive travel switch are in linkage and automatic control through a PLC control cabinet. Based on the working principle that main machine volume variable physical extrusion and auxiliary machine forced feeding extrusion are combined, the materials are conveyed, extruded and dehydrated, the equipment is especially suitable for compression forming of straw type biomass, and the compressed materials are low in water content and small in density.

Description

technical field [0001] The invention relates to a compression molding device for fibrous materials, in particular to straw compression molding equipment. Background technique [0002] At present, with the vigorous development of the second-generation bio-energy technology, industrialized use of waste straw-like biomass materials for bio-energy production has been realized. Before pyrolysis treatment, the waste straw-like biomass materials must be kneaded and compressed, and then pyrolysis treatment can be carried out to realize industrial continuous production, improve production efficiency, reduce production cost, and ensure the process indicators of process products. Due to the characteristics of waste straw biomass materials, such as large volume, light weight, large difference in moisture content, extremely poor fluidity, significant seasonality, etc., and in view of the production requirements of industrialization, straw compression equipment currently on the market bas...

AI Technical Summary

Problems solved by technology

Due to the characteristics of waste straw biomass materials, such as large volume, light weight, large difference in moisture content, extremely poor fluidity, significant seasonality, etc., and in view of the production requirements of industrialization, straw compression equipment currently on the market basically cannot Meet the compression molding requirements of such materials, for example: the straw baler can basically meet the output, density and other issues, but it has a series of problems such as high bundling costs, cumbersome transportation procedures, and inability to transport during production; ring flat grinding and pressing The block machine can basically meet the basic indicators such as density and transportation, but there are problems such as small output, high requirements for material moisture, impurities, and physical property differences, which cause frequent shutdowns in production, high labor intensity, high frequency of spare parts replacement, and high costs.
