[detailed description of the invention]
Below by specific embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of coal slime, 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 mouth (8), 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 mouth shower nozzle, and diameter is 8cm, vaporific binding agent can be sprayed, 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 base is furnished with perforation, and available screw fixes on the ground, between base and ground, places the high plank of 5cm or rubber blanket, can reduce the concussion that machine is on-stream.Motor uses 380V three phase electric machine, power 10KW, and motor to be responsible for conducting power by V-belt and gear on agitator.Have differential mechanism between motor and agitator, mixer rotating speed is controlled to 300r/min-800r/min, the ratio according to coal slime wood chip carries 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, carries out interval adjustment according to coal slime wood chip ratio.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, carries out interval adjustment according to coal slime wood chip ratio.The power of the hair-dryer of blowing mouth is provided by motor, and place metal Air Filter at blowing mouth, can prevent coal slime and wood chip from entering hair-dryer, hair-dryer wind-force is 5m/s-20m/s, and the ratio according to 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, and the ratio according to coal slime wood chip carries out intervals control.The volume of material storing box is 0.5m3, is cuboid above material storing box, and body is long is 120cm, and wide is 90cm, and below, for waiting triangle body, is filled at material storing box, when toppling over compound in mould, can is sprinkling upon on mould by compound uniformly, facilitate mould molding.Compressor reducer is by hydraulic pump drive compressing lever to provide pressure, 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 breaks 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, have every 30cm the denation that a 2cm is high, and shaping fuel is easily 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 to immediately below material storing box, adds coal wood compound; The first half mould has baffle plate in side, shaping fuel can be separated with the latter half mould, treats that the latter half mould leaves the first half mould completely, and fuel can fall down due to the effect of gravity, waits for that workman collects and process of casing.
One of material required for the present invention is coal slime.Before processing, need coal slime first to carry out drying area reason, by the water content control of coal slime between 5%-8%, carry out pulverization process afterwards, make coal slime granular size between 5mm-8mm.
