Abstract
The utility model discloses a two-step type biomass pressure moulding device, comprising a shell system, an inward turning system arranged in the shell system and a double-roll system arranged just below a discharge port of the shell system. The biomass pressure moulding device comprises two steps: first step of mixing a coarse cracking straw and a semi-dried slug to a scale and then grinding the mixture to make the material completely and uniformly mixed in smaller grains and generate heat and stick; second step of moulding the material using a groove on the double-roll under screw extrusion and double-roll rolling function; wherein the slug is used to improve the biomass moulding process, the binding property of the slug is used to improve the straw moulding mechanism and the lubrification of the slug is used to reduce the straw coarseness, therefore the two-step type biomass pressure moulding device not only effectively solves the problems that the moulding hole is blocked, the production rate is low and the device is wore but also uses waste to control waste.
Description
Technical field
The utility model relates to the biomass waste treatment technology, especially a kind of two-step biomass pressing forming equipment.
Background technology
China is large agricultural country, can produce agricultural crop straw every year and reach more than 600,000,000 ton, and wherein about 0.28 hundred million ton is used for papermaking, and 1.13 hundred million tons are used as feed, goes back the field for 1.08 hundred million tons, and 3.5 hundred million tons as fuel or waste on the spot the burning.In recent years, seasonal crop straw burning problem has become big public hazards of harm urban and rural ecological environment, it not only causes the wasting of resources and environmental pollution, and great social concern such as initiation fire, traffic are obstructed, socked-in, casualties, has a strong impact on the people's life and industrial and agricultural production.
Stalk has that generation is big, advantages such as wide, renewable and clean environment firendly distribute, its sulfur content (about 0.1%) and content of ashes (about 9%) are all far below coal, be a kind of good clean reproducible energy, be expected to one of substitute that becomes following conventional fossil energy.But, because shortcomings such as stalk has seasonality, density is little, energy is low, the dispersion that distributes, make straw collecting, transportation, storage and use all very inconvenient, many straw utilizations enterprise not only bears high freight, has difficulty in taking a step, and faces serious disaster hidden-trouble test, as though treading on thin ice.In the case, stalk compression moulding technology is arisen at the historic moment, and its know-why is: under uniform temperature and pressure effect, the softening cohesive force of lignin in the stalk strengthens, the dislocation of cellulosic molecule group, distortion and extension make to reconfigure moulding by the inner adjacent mutual bridle joint of particle.This technology can be compressed to stalk 1/10 of original volume, and pressed density reaches 0.9-1.1 ton/cubic meter.According to stalk compression moulding mode, former can be divided into roller die compaction type, spiral squeezing type and piston punching type three classes.But problems such as existing former ubiquity energy consumption is too high, service life is short, problems such as especially roller die compaction type equipment easily stops up, spiral squeezing type equipment is easy to wear, piston punching type equipment productivity is low are very outstanding, and the development of stalk forming technology is restricted.
Produce China municipal sewage plant every day a large amount of biomass sludges, its moisture content is up to more than 97%, and is difficult to dehydration, still do not have outlet preferably at present, is a great problem that many cities face.Mud comes down to the floccule that a large amount of microorganisms form by the outer polymer bonding of born of the same parents, and the main component of the outer polymer of born of the same parents is carbohydrate, fat and protein etc., and these materials have advantages of good caking property.Therefore, in biomass straw, add the mud of proper ratio, improve the material internal structure, strengthen the mutual caking property between the material particles, the compact formed mechanism of biomass straw can be changed to a certain extent, energy consumption and equipment attrition in the compact formed process can be lowered.
