Abstract

The invention discloses a biomass straw forming machine which does not need two technological processes of crushing and drying. Its technical solution is based on the existing double-outlet oil cylinders, forming devices, hydraulic systems and electric control systems, and two sets of rollers (10 , 11, 12) The rolling compact feeding device (1) that is formed is fixed on the base frame, and its discharge port is also fixedly mounted on the feed inlet of the extrusion cylinder (14) in the forming device on the base frame (13) docking; two sets of extruding heads (22) with cutting knives (23) and density adjustment head (24) are fixedly installed on the ends of two piston rods (21) of the double outlet cylinder; The far-infrared heaters for heating the biomass stalks are fixed on the outer surfaces of the two cones (18). The beneficial effect is that the technological process is simple; the equipment is simplified from the original multiple sets to one unit, which saves money; and the requirement for the moisture content of the straw is widened.

Description

technical field [0001] The invention relates to a crop straw forming device, in particular to a biomass straw forming machine. Background technique [0002] Biomass straw molding technology plays an important role in the development of new energy. Its efficiency, investment and energy consumption all directly affect the utilization of straw. People have done a lot of work for this, and have developed many crop straws. Molding device, among them, the technology and equipment of screw extrusion, rolling molding and extrusion molding are relatively mature. The process of the above-mentioned technology is pulverization, drying and molding. Screw extrusion is only used for machine-made carbon, roller compaction is used to produce pellet fuel, and extrusion molding is widely used to produce straw fuel blocks. Spiral extrusion and rolling forming require large investment, wear out parts quickly, and have low output rate. Although extrusion molding has advantages in straw fuel mo...
