Description

Multifunction straw shaped granule machine

Technical field:

The utility model is a multifunction straw shaped granule machine; it is one novel particle machine that the complete machine design has tine pulverizer, material conveyor, whirlwind, ring mould and pressure roller; need not under the electrically heated situation after involved stalk (straw, the wheat straw) raw material pulverizing; adopt pressure roller cohesive force, ambient pressure, molecular attraction, inlay the frictional force technology, make crops straw, wheat straw curing molding particle.

Background technology:

China is large agricultural country, and about 7.2 hundred million tons of annual according to statistics stalk wherein accounts in 19%, 21% the agriculture and forestry organic waste material of stalk resource straw, wheat straw resource and is not fully used.Its reason is because straw, the wheat straw volume is big, density is little, is difficult for storing, and chlorinity height in alkali, the ash, fusing point is lower, and calorific value is lower, is easy to generate the shortcoming that slagging scorification, pipeline are blocked etc. in gasifying stalk, often is not utilized.Annual rural area produces a large amount of straw, wheat straws and does the meal except that being made a fire as native kitchen range by the peasant on a small quantity, and the overwhelming majority is burned and commits to the flames, has brought pollution to environment, has brought potential safety hazard for highway, civil aviaton's transportation, more it's a pity and has wasted precious resources.

Domestic production granulator equipment has following several at present: (1), Wet-pressing molding technology: after fiber-like raw material normal temperature soaks a few days down; soft, moistening, also part degraded corruption of crowfoot cracks that its fiber becomes; compare with general air-dry raw material; can lose certain energy; but its compression performance obviously improves, and is easy to compression forming.This technology is widely used in the production of fiberboard, can form low-density compression forming fuel slug, and productivity ratio can reach 1t/h; (2), hot press forming technology: the extrusion forming technology that adopts in the hot press forming technology mainly contains screw extrusion technology, piston stamping technology, and punching type, fluid pressure type all need outer heating, energy consumption height, fixed maximization, the processing of the edge of a field, incompatibility rural area.

Summary of the invention

The utility model proposes the multifunction straw granulator; being intended to overcome present curing molding granulator can not be with crops straw, the existing above-mentioned technological deficiency of wheat straw curing molding; preferred ring mould is the compact formed technology of particle of one with pressure roller and functions such as pulverizing and whirlwind: because contain the lignin of 10%-18% in the stalk, (110-160 ℃) can take place to soften at a certain temperature.Select above-mentioned new technology when work, straw after the pulverizing, wheat straw are subjected to the effect (cohesive force, ambient pressure, molecular attraction, inlay frictional force) of four kinds of pressure, material is under ring mould and the powerful extruding of pressure roller, the frictional force heat of pressure by evenly producing during in moulding in the aperture on the annular press mold, make the softening and cellulose bonding of lignin, cooling back curing molding.Need not outer heating.The miniaturization of this machine, power consumption is few, is convenient to move, and is adapted at family and field move operation.

Technical solution of the present utility model: it is characterized in that carrier pipe and tine chain connect, safety guard links with casing, change to take out and be connected with motor, belt is taken out with motor with commentaries on classics and is linked, motor links with base, universal wheel links with base, belt pulley connects with the ring template strand, and high power motor links with gear-box, and sieve plate links with casing, casing links with base, gear-box links with casing, and the ring mould links with gear-box and hopper, and hopper links with ring mould and silk screen cover, the silk screen cover links with hopper and whirlwind, and whirlwind links with carrier pipe and silk screen cover.

Basic pressure roller principle: be subjected to 4 kinds of power in the agricultural crop straw curing molding process: bonding knot, ambient pressure, molecular attraction, inlay frictional force.Briquetting pressure is generally 10-30mpa, and the principal element that influences the pressure size is the content of lignin in the stalk.After straw, wheat straw are pulverized; ring mould granulator is under the drive of power; pressure roller rotates at a high speed; the frictional force that normal pressure produced by the raw material hand-hole drives the pressure roller autobiography; send into 2 pressure rollers equably and encircle the blanketed zone that mould is formed by 2 deflection scrapers on feeder and the header board again, by 2 relative revolving parts of ring mould and pressure roller material is pushed gradually and clamp-on the ring nib, moulding in nib; and constantly extrude outward, at last shaped granule is discharged outside the machine.Because ring mould and pressure roller all are columniform, so each the bar linear velocity on the ring mould inwall is all the same, under the effect of speed frictional force, to roll between speed and pressure roller, interaction force is more even between the two.

Advantage of the present utility model: 1, multi-functional: having tine pulverizer, material conveyor, whirlwind, ring mould and pressure roller is one novel particle machine, the two-shipper synchronous operation system is stable, harmony is good, can can extrusion modling be the particle that differs in size again both singly with pulverizing various agriculture and forestry organic waste material stalks; Can be placed on indoor fixedly use, can flow to the field again and use (loading onto diesel engine) flexibly, also can do small processing factory and concentrate use.2, power consumption is little: this unit can be selected motor or diesel engine (13 kilowatts of electric motors function, the diesel engine function is more than 15 horsepowers) for use according to user's actual conditions, and 1 ton of straw of every production, wheat straw particle only need 15kw; 2, cost low (power consumption 30-35 unit, 20 yuan of labour costs, 10 yuan of maintenance costs), the peasant affords to use, and gasification centralizedly supply station has solved the hang-up of buying raw material; 3, simple to operate: this machine adapts to the peasant to be used, operating procedure is simple, can the click car, and by have down, clockwise switch, with opening with stopping, one people can produce (particle one subsynchronous finishing cut, made to charging, hand hay cutter), has particularly alleviated labor intensity of operating staff and has improved the working environment that dust is existed everywhere; 4, calorific value height: detect according to national R﹠D institution: making fuel gases calorific value with straw, the wheat straw do not processed is: the combustion gas that 3663.6KJ/M3 makes (about 1100 kilocalories/M3), and the fuel gases calorific value made from the straw of this machine production is up to 15048-15884kJ/kg, the fuel gases calorific value that the wheat straw particle is made is grown (combustion rate 〉=92%) up to 16302-16720kJ/kg burning time.This particle can replace coal to use with family heating, family's small evaporator stove making a fire and make meal, improve rural environment.
