Biomass extruding and molding combined unit

Abstract

The invention relates to a biomass extruding and molding combined unit which is formed by a power device, an operation control device, a cutting device, a rolling device, an extruding and molding device, a finished-product squeezing and cutting-off device and a weighing and packaging mechanism device and is mounted on the same rack. The biomass extruding and molding combined unit can continuously make biomasses including fine and soft rice and wheat straws, rough and hard bamboo, wood, cotton and bean stalks, palms, sugarcanes, rattans, potato rattans, corn cores, stalks and the like into molded products. Particularly, a gear pair is used for carrying out repeated S-shaped rolling on the materials after the materials pass through a gear top, a gear surface and a gear root to be cracked in a radial direction, so that elastic stress is degraded, and a gap is manufactured for contained sugar and lignin to be thermalized and smelted until a thin-sheet-wire net shape is formed and the softening is realized; and in a squeezing process, residual elastic stress can be degraded, a porous hollow molded block in a single-hole pipe shape or a coal ball shape can be extruded by sufficient and uniform yielding and deformation, and dense adhesion, or a spiral and straight convex rib is extruded or a circular and non-circular molded block of a groove is extruded. Particularly, the invention provides the biomass extruding and molding combined unit which is mounted on a combined harvesting machine and takes power to link or walk along with the combined harvesting machine.

Description

[0001] The invention relates to a device for processing renewable biomass materials, which is composed of power, operation control, shearing, rolling, extrusion molding, finished product extrusion and disconnection, and weighing and packaging mechanisms, and is installed on the same frame. Agglomerated into fuel blocks to generate energy, to partially replace non-renewable coal, oil, and natural gas in a biomass extrusion unit. Background technique [0002] Biomass blocks (briquetting for short) in the background technology are made by extrusion molding machines with flat (straight) extrusion and ring (side) extrusion mechanisms (with an electric control box, briquetting machine for short). The briquetting machine also needs a front-mounted cutting mill and a belt conveyor to form a system production capacity, so it cannot achieve continuous joint work, and it occupies a large area, the matching between power and machinery is poor, and the power waste is large.

AI Technical Summary

Problems solved by technology

[0004] 1. The extrusion wheel of the parallel extrusion and ring extrusion mechanism rotates once with the main drive shaft and can only perform tangential extrusion movement with gaps in the small area and small dose of one pair or two pairs of holes in an instant, directly and effectively. Less, high no-load ratio, and a lot of waste of functions

[0005] 2. The power unit is a motor of 30KW or more than 50KW, and the power transmission distance from the power transmission mechanism to the extrusion wheel is relatively long.

The rolling bearing of the squeeze wheel is difficult to achieve no gap dustproof sealing protection, and it is difficult to replenish lubricating grease and heat dissipation

[0007] 4. The extrusion of the extrusion wheel and the die set of the flat die plate and the ring die plate is tangential extrusion instead of axial extrusion, which requires large force and low efficiency, and there is no manual or automatic extrusion gap. Randomly adjust the mechanism device for compensating the extrusion, so the extrusion cannot be kept in the best clearance condition, so the extrusion work efficiency is low

[0008] 5. The cutting machine of the supporting equipment of the briquetting machine is a mechanism in which the suspended rice and wheat straws move towards each other randomly and then collide with them to crush them. Therefore, it is impossible to cut all the materials with relative rigidity and fixed length. Although it can crush low-density, thin and soft rice and wheat straws in the air without fixed length, but it can crush high-density, thick and large bamboo (stalks, branches, leaves), wood (bark, branches, leaves), corn Cores and stems, cotton, beans, palms, sugar cane, vines and potato vines, etc. are difficult to cut to length, and there is no rolling mechanism, so axial shearing, radial cracking and extrusion cannot be achieved. Thickness, hardness, evenness, length required for molding

[0010] For the lack of background technology, many manufacturers have proposed improvement plans, such as increasing the power of the motor to increase the output of cutting and extrusion, but the load of the electric meter of the farmer is limited, so it is difficult to implement
