Double-extrusion biomass crushed material forming machine

Abstract

The invention discloses a double-extrusion biomass crushed material forming machine. The double-extrusion biomass crushed material forming machine is characterized in that a smooth roll of the double-extrusion biomass crushed material forming machine can be driven by a driving wheel, and separate driving teeth are arranged on the driving wheel and can mesh with a driven wheel or can be separated from the driven wheel, so that a grooved roll connected with the driven wheel can be driven to rotate intermittently; barriers which extend along the length direction of the grooved roll are arranged on the sides of the grooved roll, two secondary extrusion cavities are enclosed by two adjacent forming grooves when the barriers and the grooved roll rotate and reach the two adjacent forming grooves, and two hydraulic push rods which are matched with the two secondary extrusion cavities are arranged at the ends of the grooved roll. The double-extrusion biomass crushed material forming machine has the advantages that the barriers are matched with the forming grooves in the grooved roll, so that the secondary extrusion cavities can be formed; biomass crushed materials in the secondary extrusion cavities can be secondarily extruded by the hydraulic push rods, accordingly, the density of finished products can be greatly improved, and combustion values of the finished products can be increased; the biomass crushed materials are secondarily extruded, accordingly, the finished products have certain strength, and transportation and utilization in late periods can be facilitated.

Description

technical field [0001] The invention relates to the field of molding and processing of straw-like biomass, in particular to a double-extrusion type biomass pulverized material molding machine. Background technique [0002] Biomass includes several categories of organic matter produced by plants through photosynthesis, such as plants, animals and their excrement, garbage and organic wastewater. Biomass energy comes from the sun, so biomass energy is a type of solar energy. Biomass is the most important absorber and storage of solar energy. Biomass can accumulate solar energy through photosynthesis and store it in organic matter. In the prior art, biomass is widely used to prepare pellet feed and fuel. When straw biomass is used, it must be crushed first, and then made into a specific module according to a certain molding method. The current production mainly adopts screw extrusion, ring die, etc. to form biofuel blocks. For the new roll forming method, it is mainly formed ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of adhesion in the molding tank caused by expansion after heating and pressure during the molding process of biomass pulverized material and the problems of low density, large volume and easy breakage of the final produced finished product block, the present invention provides a double extrusion Biomass pulverized material molding machine, this molding machine can perform secondary extrusion on the biomass pulverized material that has been extruded in the forming tank, which not only prevents the biomass pulverized material from adhering to the inner wall of the forming tank, but also greatly improves the The density of the final produced biomass blocks is improved, thereby improving production efficiency
