[specific embodiment]
Below by specific embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, coal slime, a wood chip mixed-forming machine, it comprises base (1), motor (2), differential mechanism (3), coal slime charging aperture (4), wood chip charging aperture (5), transmits crawler belt (6), blowing mouth (7), binding agent interpolation mouthful (8), an agitator (9), agitator flabellum (10), material storing box (11), compound transmission crawler belt (12), mould (13), compressor reducer (14), machine fixed support (15).
Wherein, coal slime charging aperture width is 16cm, wood chip charging aperture width is 16cm, coal slime charging aperture is 20cm place above wood chip charging aperture, and it is Round Porous shower nozzle that binding agent adds a mouthful shower nozzle, and diameter is 8cm, can spray vaporific binding agent, binding agent adds mouth 45cm place below wood chip charging aperture, blowing mouth diameter 20cm, 60cm place below wood chip charging aperture.
Base adopts the pig iron to cast, and is furnished with perforation on base, and available screw fixes on the ground, between base and ground, places high plank or the rubber blanket of 5cm, can reduce the on-stream concussion of machine.Motor uses 380V three phase electric machine, power 10KW, and motor is responsible for by V-belt and gear, power being transmitted on agitator.Between motor and agitator, there is differential mechanism, mixer rotating speed is controlled to 300r/min-800r/min, according to the ratio of coal slime wood chip, carry out intervals control.The load mode of the coal slime of coal slime charging aperture is Rubber Conveyor Belt Scrap, and conveyer belt transfer rate is 20cm/s-240 cm/s, according to coal slime wood chip ratio, carries out interval adjustment.The load mode of the wood chip of wood chip charging aperture is Rubber Conveyor Belt Scrap, and conveyer belt transfer rate is 20cm/s-240 cm/s, according to coal slime wood chip ratio, carries out interval adjustment.The power of the hair-dryer of blowing mouth is provided by motor, at blowing mouth, places metal Air Filter processed, can prevent that coal slime and wood chip from entering hair-dryer, and hair-dryer wind-force is 5m/s-20m/s, according to the ratio of coal slime wood chip, carries out intervals control.It is shower spraying head that binding agent adds mouth, and the speed of spraying binding agent is 5ml/s-20ml/s, according to the ratio of coal slime wood chip, carries out intervals control.The volume of material storing box is 0.5m3, and material storing box top be cuboid, and body is long is 120cm, and wide be 90cm, and below such as is at the triangle body, at material storing box, fills, and when toppling over compound in mould, can uniformly compound be sprinkling upon on mould, facilitates mould molding.Compressor reducer is by hydraulic pump drive compressing lever so that pressure to be provided, and hydraulic pump uses three-phase 380V voltage, and the pressure of generation is 50MPa-70MPa.
Mould is cylindrical shape, long 120cm, diameter 9cm.Mould adopts manganese, chromium mixing open die forging to break into type, and this mould wearability is good, and rigidity is strong.In mould, mould is divided into two parts, and upper/lower die is all hemicycle cylinder, and two parts are combined into a complete mould, every 30cm, have a denation that 2cm is high, and the fuel of moulding can easily be disconnected, and is convenient to burning; 10 row's moulds are a set of molds; The latter half of mould is fixed on a removable geosyncline, and after each compression forming, geosyncline moves longitudinally under material storing box, adds coal wood compound; The first half mould has baffle plate in side, can the fuel of moulding is separated with the latter half mould, treat that the latter half mould leaves the first half mould completely, and fuel is because the effect of gravity can fall down, and waits for workman's processing of collecting and case.
One of material required for the present invention is coal slime.Before processing, coal slime first need to be carried out to drying area reason, the water content of coal slime is controlled between 5%-8%, carry out afterwards pulverization process, make coal slime granular size between 5mm-8mm.
Two of material required for the present invention is wood chip.Before processing, wood chip need to be carried out to airing processing, the water content of coal slime is controlled between 8%-10%, afterwards the wooden unit comprising in wood chip be carried out to pulverization process, make its shape approach the wood chip of tree leaf-shaped, 8 square centimeters of extension areas are best.
The transfer rate of coal slime conveyer belt is adjusted to 70cm/s, the transfer rate of wood chip conveyer belt is adjusted to 30cm/s, what binding agent was used is calcium lignosulfonate, and interpolation speed is adjusted to 10ml/s, and the air rate adjustment of blowing mouth is to 8m/s; Coal slime, wood chip and organic binder bond can effectively mix under the effect of wind-force above agitator, afterwards because Action of Gravity Field is fallen agitator below, under the effect of agitator flabellum, again mix, after mixing fully, compound transmits crawler belt to be added compound in material storing box to, when material storing box reaches material storing box normal line and is 0.4m3 reserves, crawler belt stops transmitting.Mould the latter half is slided into by geosyncline under material storing box, and after material storing box is toppled over compound, crawler belt continues to transmit compound; The latter half mould carries compound and is slided into behind the first half mould below by geosyncline, and compressor reducer carries out squeeze operation, is the output object of patent of the present invention after compound moulding.After moulding, the latter half mold-slide is to material storing box below, and after departing from the first half mould completely, output object is because Action of Gravity Field splits away off, by operative employee's processing of collecting and case.
After testing, adopt the calorific value of the coal slime wood chip section bar that this kind of method prepare can reach 80-90 million Jiao/kilogram, can meet the requirement as fuel completely.
One large feature of patent of the present invention is when coal slime, wood chip enter agitator, under the wind-force effect of hair-dryer and the gravitational difference of coal slime and wood chip, can make coal slime, wood chip have enough incorporation times aloft, like this when coal slime, wood chip drop to agitator bottom, most of mixing fully, improved the speed of mixer output compound.In the forming machine of common single composing type mould, agitator carries out the interpolation of compound after need to waiting for mould compression forming again, and patent of the present invention has been used material storing box, and compound is stored in material storing box, by material storing box, indirectly carried out the interpolation work of compound, greatly improved production efficiency.
Patent of the present invention is applicable to the forming operation of other combustibles equally.
