Description

A kind of straw squeezes stranding machine
Technical field
This utility model belongs to biomass fuel technical field, is specifically related to a kind of straw and squeezes stranding machine.
Background technology
In recent years owing to life in the countryside level improves, the dependency of crops stalks fuel is reduced by peasant, causes and has a large amount of agricultural crop straw to retain every year, processes to straw and the spring ploughing in the coming year brings no small trouble.Due to the reasons such as soil horizon is thin and farming has high input ploughed, the deep ploughing also field of straw being processed to implement difficulty big, abandon stacking and take again a large amount of cultivated land resource, therefore peasant is many for the processing mode of straw or adopt directly burning.But crop straw burning does not only exist the risk of initiation fire, also results in air pollution, this had both endangered environment, wasted again resource.In recent years, government just forbids that crop straw burning problem has put into effect a lot of way and suggestion, but all without receiving significant effect, reason of searching to the bottom, it is straw as a kind of biomass energy not by effective exploitation and utilization, also fails to embody its due society and commercial value.
Meanwhile developing rapidly of China's economy consumes the substantial amounts of energy, and this not only results in the minimizing year by year of fossil energy, along with the problem of environmental pollution that increases of energy resource consumption is also on the rise.Therefore want the process accelerating China's new road toward industrialization and Realization a Fairly Well-off Society in a all-around Way under the premise of protection environment, be necessary for utilizing regenerative resource to replace and supplementary traditional energy.Agricultural crop straw is exactly good biomass energy, and straw, after the solid fuel that former is squeezed into quality densification, regular shape, has that volume is little, density is big, accumulating is convenient;Grade is higher, fuel characteristic is excellent;Green non-pollution, clean hygiene, the advantage such as easy to use, it is possible to the alternative ore energy is widely used in people and produces and the every field of life.Thus alleviating the depletion rate of the resources such as coal, reduce the discharge capacity of dusty gas, improve the energy resource structure of China, for ensureing national energy security, improve the ecological environment, promote energy-saving and emission-reduction, realize low-carbon economy, providing for new countryside construction clean energy resource to be respectively provided with important meaning.
Biomass fuel block curing molding technology is broadly divided into hot compression forming technique, cold compression forming technique and carbonization forming technique.Hot compression forming technique refers to;Biomass material is heated between 170 DEG C-220 DEG C, by applying certain pressure, biomass material is compressed to the shaped fuel with certain density.Its moulding mechanism is by the mode heated, and makes the lignin in biomass material soften.Lignin is at normal temperatures insoluble in any organic solvent, but when temperature is at 200-300 DEG C, lignin can soften because of the change of temperature.By it is applied certain pressure in the process of lignin softening, the materials such as the cellulose in itself and biomass material can be made to closely bond concurrently raw mechanically deform and plastic flow, it is being perpendicular in direction of maximal stress, particle is mainly to engage each other, and it is being perpendicular on minimum stress direction, particle mainly combines in the way of being mutually close to, and gets final product curing molding after cooling.
Current biomass molding fuel both domestic and external produces equipment mainly roller single lead screw ex truding briquetting machine, screw rod continuously extruding and molding machine, Mechanical Driven impact briquetting machine and hydraulic-driven impact briquetting machine.Many technical problems such as these formers are all widely present that operating power consumption is high, production efficiency is low, die wear is serious, biomass fuel quality characteristic after molding differs greatly.
Piston type heat pressing forming machines, including: plastic zone (pre-extrusion), buckling district (fine and close extruding), Bao Xingqu (mould) and heater, after extruding from material Bao Xingqu, biomass fuel extrusion block natural cooling sizing.In order to ensure that extrusion block not generation type becomes, it has to lengthening mould, friction stroke is long;What have installs trunnion additional between buckling district and Bao Xing district, increases frictional force, and mould abrasion also increases, sacrificial mold, wastes the energy.
Biomass profiling equipment is the key that farm crop straw organism matter shaped fuel produces, and its production efficiency decides the yield of biomass molding fuel, and technical specification decides the quality of biomass molding fuel, and energy consumption decides the production cost of biomass molding fuel.Therefore, efficient, the energy saving biomass forming production device of development of new is the primary problem of biomass molding fuel industry development.
Kneading machine is mainly made up of components mechanisms such as feeding unit, rotor mechanism, tooth plate and blower fans, and the hammer leaf in rotor mechanism generally more adopts helical arrangement, and the straw after rubbing generally becomes thread, but kneading machine exists production efficiency is low, energy consumption is high problem;Rub broken formula and pulverize the coalition being guillotine cutting with pulverizing, through the material that puy processes, generally present the thread of soft fluffy more.
