Description
Technical field:
The utility model relates to a kind of special-purpose industrial furnace, waste material wood powder that especially available timber processing produces or wood chip replace a kind of with the hot-blast stove of wood powder bits for coal of fire coal or fuel oil.
Background technology:
In the prior art, technique known is to authorize disclosed No. 200620023337.5 patents by State Intellectual Property Office, this patent disclosure a kind of technical scheme of wood powder combustion furnace, this scheme is that round-meshed fuel outlet on the seedpod of the lotus shape is arranged in body of heater, on the circular hole of fuel outlet disperser is arranged, wood powder is sent into by blower fan, is sprayed by the circular hole on the fuel outlet, through disperser wood powder is vaporific distribution, realizes the continuous burning of wood powder.Solved with timber be raw material sheet material manufacturing enterprise in process of production, the a large amount of wood powder waste materials that produce utilize again, and can produce the heat that can be used for producing, but in the waste material of sheet material manufacturing enterprise, not only has only wood powder, also have a large amount of wood chips, and this scheme is unserviceable to wood chip, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of with the hot-blast stove technical scheme of wood powder bits for coal, the not only available wood powder of this scheme is a fuel, and can be fuel with wood chip, the all waste thing that sheet material manufacturing enterprise is produced in process of production all can be used as fuel combustion, and makes the heat of generation feed back to production.
This programme is realized by following technical measures: comprise having the body of heater that is incubated the furnace wall, burner hearth, flue and fire grate are arranged in body of heater, air compartment is arranged below fire grate and connect ash bucket, described air compartment is connected with air blast again, described flue also is connected with air-introduced machine, the characteristics of this programme are that described fire grate is the fire grate of tilt installing, and are connected with the fire grate push rod on fire grate, and this fire grate push rod is connected with driving fire grate hydraulic cylinder shaft outside the furnace wall; At least two wood chips inlet is arranged on the high-end furnace wall of fire grate, and each wood chip inlet connects wood chip conveying pipeline separately respectively, and each wood chip conveying pipeline connects wood chip hopper, connects to fall the slag passage at the low side of fire grate; On the furnace wall above the wood chip inlet at least two wood powder spouts are arranged, each wood powder spout is connected with the wood powder input pipe; On the furnace wall above the wood powder spout, also has heat-exchange tube.The concrete characteristics of this programme also have, described fall the slag passage with connect ash bucket and also be connected with the ash discharge passage of bottom of furnace body.Described wood chip hopper also is connected with the wood chip feeder.On described body of heater, also have a plurality of peep holes.The urgent exhaust opening that the band control valve is arranged at described body of heater top.Air outlet at described air-introduced machine is connected with the hot blast efferent duct.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, fire grate is the fire grate that tilts, on fire grate, be connected with the fire grate push rod and be connected with driving fire grate hydraulic cylinder shaft outside the furnace wall, fire grate is under the driving of hydraulic cylinder like this, can be reciprocating, form reciprocal grate, impel the material that burns on the fire grate to move and burn after lime-ash come off.Wood chip inlet is arranged on the high-end furnace wall of fire grate, and the wood chip inlet connects wood chip conveying pipeline and wood chip hopper, connects to fall the slag passage at the low side of fire grate.This structure can be with the combustibles such as bulky grain wood chip that can not carry with wind-force, are sent to by the wood chip inlet on the fire grate of burner hearth to burn, and the lime-ash after the burning falls into the slag passage and discharges.On the furnace wall above the wood chip inlet wood powder spout is arranged, the wood powder spout is connected with the wood powder input pipe.This structure can be with powdery timber or the fiber that can carry with wind-force, be blown into the burner hearth burning with wind-force by wood powder input pipe and wood powder spout, because the very light in weight of wood powder, so its combustion zone is the top in the wood chip combustion zone, so just having formed the bottom is the wood chip combustion zone, top is the hot-blast stove of the double-deck burning of two kinds of fuel of wood powder combustion zone, makes all production wastes of sheet material processing enterprise comprise wood powder and wood chip, can be as the fuel of this boiler.Be added in the heat-exchange tube that is full of oily medium on the furnace wall of burner hearth top in addition again, be defeated by workshop by heat-exchange tube after with the oil heating and be used for production and processing.And the hot blast in the body of heater is exported by the hot blast efferent duct by air-introduced machine, removes to produce steam or directly be passed to workshop to be used for production and processing.This shows, the utility model is to use sheet material manufacturing enterprise, all waste materials that produced in process of production are fuel, produce enterprise and produce required heat, realize that internal enterprise resources is recycling, this has not only reduced the cost of product, and can save energy reduction of discharging and reduce environmental pollution, so compared with prior art, have substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
