Description
Technical field
The invention belongs to the biomass compact forming processing technique field, relate to a kind of biomass compact contour machining method.
Background technology
At present, widely used biomass compact contour machining method is mainly by two kinds of cold forming and thermoformings.In the thermoforming processing method, raw material makes after needing drying or natural air drying operation man-hour usually its water content reduce adding, preliminary treatment such as pulverize then after, carry out processing and forming again, compact density is bigger, and molding effect is better, needs after the machine-shaping to cool.The raw material stoving energy consumption is bigger, installs also more complicated.Cold forming processing does not need drying to equal to handle to the humidity requirement broad of raw material, and moulding does not also need to heat, and energy resource consumption is lower, and the back grain density that is shaped is less.
Existing forming method has screw extruding bri quetting, die pressing type moulding and piston type punch forming several types.Screw extruding bri quetting is to utilize the lignin of living beings being heated to the characteristic that can soften under the proper temperature (130-200 degree centigrade), and with the living beings heating, pressurization makes its curing molding then.In the method, raw material need be dried to moisture content below 13%, utilizes screw extruder extrusion modling at high temperature after the pulverizing, and therefore the temperature of the back dense granule that is shaped, need be cooled to normal temperature and could pack, transport generally all more than 90 ℃.The energy consumption of processes such as drying, heating, extruding and cooling is all very high, and therefore, generally speaking, the power consumption of one ton of biomass compact forming product of every production all is higher than 100 kilowatt hours, have in addition reach 200 kilowatt hours per ton; And, screw extrusion part work under bad environment, the life-span is very short, the life-span of screw rod has only about 100 hours usually, have in addition less than 20～30 hours.
The die pressing type forming method comprises ring mode, flat-die type powdered and several moulding patterns of pair roller type.Ring mode and flat-die type powdered moulding are to roll on anchor ring on ring mould with moulding hole or the flat-die or plane by a pressure roller, and the raw material of certain fineness is compressed into the extrusion modling of moulding hole.Material is pressed in the process of moulding hole with respect to ring mould or flat-die rolling at pressure roller; slip between pressure roller and the material makes material compress into the moulding hole and encounters difficulties; in addition; give birth to heat owing to slide and make that also material temperature rise in its forming process is very big, general moulding hole exits place material temperature is all about 90 ℃.Suppress the high like this particle of temperature, generally also will cool off, just can pack then, transportation etc.Cooling has also increased energy consumption.Simultaneously, because heat is given birth in sliding friction, make ring mould and roller temperature raise, work under bad environment causes reduce its service life.In addition, in ring mode, flat-die moulding, pressure roller needs frequently to change than the serious wear of ring mould or flat-die.For its wearability is provided, when making, to make high-frequency quenching and handle piece surface, thereby the expense costliness.
In the processing of existing ring mold forming, generally all be that the ring mould rotates, pressure roller static in the ring mould (also be designed to encircle mould and pressure roller all rotates).Material is extruded from the perforate of ring mould by the extruding of ring mould inner surface and pressure roller outer surface.Such process mainly leans on the frictional force on material and pressure roller, ring mould surface to bring material into the moulding aperture, and then the normal pressure on pressured roller surface is compressed into the moulding hole forming with material.As the patent No. is 200720012093.5 patent, is the relatively rotating material extrusion molding hole of pressured roller and mould; The patent No. is 02153380.6 patent, is that variation by moulding hole dimension and shape improves material and enters the quantity in moulding hole and compression quality.As above analyze, by the rolling of ring mould, pressure roller, in case normal pressure deficiency (or the bed of material in moulding aperture is lower than the bed of material on every side) in such process, or the lip-deep bed of material of ring mould is blocked up, between ring mould and pressure roller, form a pad, so just be difficult to material is compressed into forming cavity.Thereby be easy to form the low or traffic congestion of shaping efficiency.
Summary of the invention
The objective of the invention is to improve in the existing ring mold forming technology, biomass compact forming method energy consumption height, equipment is easy to wear and the adaptation of product is poor, the shortcoming that can not adapt at present most boiler oil requirement, a kind of novel biomass compact forming method is provided, this method is started with from each product processing link, change the combustion characteristics of product, cut down the consumption of energy, to adapt to the requirement of at present growing biomass compact forming fuel.Improve the distribution situation of material between ring mould and the pressure roller,, between ring mould and pressure roller, be not easy to form material and overstock because profile of tooth is concavo-convex, and, improve making material enter the effect situation of the active force-normal pressure in moulding hole, thereby shaping efficiency is improved.
Further aim of the present invention is to provide a kind of method of novel biomass material moulding, can reduce the power consumption that produces owing to material and mould, roller mantle friction, improves working (machining) efficiency.
