Abstract
The utility model discloses a straw pallet burning hot blast furnace which comprises a grate arranged on the lower side of the interior of a furnace body, a blowpipe facing the grate, a fuel tank arranged on the outer side of the furnace body, a spiral propeller arranged on the lower part of the fuel tank and an electric heating pipe arranged at the bottom of the grate; one end of the spiral propeller is connected with a motor and a speed reducer, and the other end thereof extends to a combustion chamber of the furnace body and is placed in the fuel feed pipe above the grate, the blowpipe is also communicated with a smoke backflow prevention blowpipe, the other end of the smoke backflow prevention blowpipe is communicated with the outer tube body of the spiral propeller, and at least more than 1 blow port is arranged on the outer tube body. The straw pallet burning hot blast furnace is efficient and energy saving, automatically ignites and is convenient in use, generates no tar during combustion and is extensively applicable to hot blast dryers and hot blast heating furnaces.
Description
Technical field
The utility model relates to a kind of combustion stalk particle hot-blast stove.
Background technology
At present, known heating steam stove is the individual layer stone or metal plate for standing a stove on as a precaution against fire, establishes air inlet and heat exchanger thereon, establishes hot-blast outlet thereon, and its shortcoming is power consumption, consumption gas, the manual firing, and it is insufficient to burn, and there is the potential safety hazard of blast in hot-blast stove.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-efficient, environmental protection, igniting automatically, combustion stalk particle hot-blast stove safe in utilization for the deficiency that overcomes the prior art existence.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of combustion stalk particle hot-blast stove, include the fire grate that below, body of heater inside is provided with, the blower that leads to fire grate, wherein also include the fuel tank that the body of heater outside is set, the spiral propeller that the fuel tank bottom is provided with, the electrothermal tube that is provided with in the fire grate bottom, described spiral propeller one end is connected with motor and decelerator, the other end is communicated in the fuel input pipe that stretches into the combustion chamber in the body of heater and place the fire grate top, described blower also is communicated with an anti-flue gas refluence blower, should be communicated on the outer tube body of spiral propeller by the anti-flue gas refluence blower other end, and between the two, the blowing mouth more than 1 is set at least.
Described should anti-flue gas refluence blower with the flow distribution plate of drying is set in blower is communicated with the place.
The angle of described blowing mouth is toward fuel input pipe.
Above described combustion chamber heat exchanger is set, the body of heater top is provided with air inlet, and the body of heater below is provided with hot-blast outlet, and the heat exchanger upper and lower connects and leads to respectively in air inlet and hot-blast outlet, between air inlet and the heat exchanger axial flow blower is installed.
Described fire grate is a basin shape fire grate.
Owing to adopt said structure, be provided with electrothermal tube in the stone or metal plate for standing a stove on as a precaution against fire bottom, therefore adopted electronic ignition mode, need banking fire in burner hearth, to prevent in banking fire process gas explosion taking place, accomplish safety in production.Increase to be provided with and prevent flue gas refluence pipe, can increase stalk fuel and enter the combustion chamber smoothly, increase combustion-supporting wind-force, main is to prevent that the flue gas in the combustion chamber from flowing backward to fuel tank, guarantees the safety of fuel tank thus and prevents that surrounding air from being polluted.Do not produce tar in the utility model combustion process, can be widely used in air drier, hot blast warming stove.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of combustion stalk particle hot-blast stove, include the basin shape fire grate 15 that body of heater 2 inner belows are provided with, the blower 11 that leads to fire grate 15, wherein also include the fuel tank 5 that body of heater 2 outsides are set, the spiral propeller 6 that fuel tank 5 bottoms are provided with, the outer electrothermal tube 21 that is with pipe box 17 that is provided with in fire grate 15 bottoms, described spiral propeller 6 one ends are connected with motor and decelerator 7, the other end is communicated in the fuel input pipe 18 that stretches into the combustion chamber 14 in the body of heater 2 and place fire grate 15 tops, described blower 11 1 ends are connected with air blast 9, the other end is communicated in the air inlet 20 of basin shape fire grate 15 bottoms and the secondary air mouth 16 of sidepiece, on blower 11 bodies, also be communicated with an anti-flue gas refluence blower 8, should anti-flue gas refluence blower 8 be communicated with the flow distribution plate 10 of drying is set in the place with blower 11, so that the wind that air blast 9 is blown into is once shunted, a part flows to fire grate side, a part blows into anti-flue gas refluence blower, should be communicated on the outer tube body of spiral propeller by anti-flue gas refluence blower 8 other ends, at the blowing mouth 22 that is provided with at least on its outer tube body more than 1, the angle of described blowing mouth 22 is toward fuel input pipe, so that wind is to the combustion chamber.Above described combustion chamber 14 heat exchanger 4 is set, the body of heater top is provided with air inlet 1, and the body of heater below is provided with hot-blast outlet 19, and the heat exchanger upper and lower connects and leads to respectively in air inlet and hot-blast outlet, and axial flow blower 3 is installed between air inlet and the heat exchanger.Body of heater arranged outside electric cabinet 13.
During use, start spiral propeller 6, air blast 9 and axial flow blower 3, connect electrothermal tube 21 simultaneously by electric cabinet 13; The stalk particle of putting into fuel tank 5 is pushed into the basin shape fire grate 15 of combustion chamber through spiral propeller 6, fuel input port 18, electrothermal tube 21 is lighted a fire automatically when the time comes, behind the wind ignited fuel by air blast, electrothermal tube is outage automatically after 3 ~ 5 minutes, fuel burns away, flue gas through heat exchanger 4 heat exchange after smoke exhaust pipe 12 discharge; Behind axial flow blower, heat exchanger, send hot blast from the fresh air that air inlet 1 is come in by hot-blast outlet 19.After reaching the temperature that is set at heat supply temperature, at first spiral propeller outage stops the input of fuel, and air blast continues blowing 3 ~ 5 minutes, and all burnt on the fire grate, in case the combustible gas blast takes place, afterwards, air blast cuts off the power supply automatically.When heat supply temperature drops to the temperature that is set when following, restart, its job step is identical with the aforesaid operations step.
