Abstract

The utility model discloses a dual-purpose hot-air furnace, comprising a furnace body, a gas-air heat exchanger above the furnace body, a chain grate at the bottom of a hearth, a small arch in the hearth, a fuel feeding device at the front end of the furnace body, a furnace setting chamber at the back end of the furnace body, a gas duct, and a slag cleaner below the furnace body, wherein the fuel feeding device is composed of a coal feeding unit and a rice husk feeding unit arranged above the coal feeding unit. The dual-purpose hot-air furnace can alternatively change coal fuel and rice husk fuel in the same hot-air furnace according to user's requirements.

Description

A kind of dual-purpose hot-blast stove
Technical field
The utility model relates to a kind of air heating plant, especially a kind of hot-blast stove that hot blast is provided for foodstuff drying device.
Background technology
In order to prevent that grain from going mouldy in storage, transportation and process, usually to use foodstuff drying device that wet grain is dried in storage, long-distance transport and first being processed, make the water content in the grain reach required standard, and hot-blast stove is the key equipment that thermal source is provided for foodstuff drying device, its performance directly influences the grain heat-drying effect, at present domestic for foodstuff drying device provides the hot-blast stove kind of thermal source more, mainly contain coal-fired hot-blast stove, warm air oil furnace, fuel gas hot-blast stove and combustion rice husk hot-blast stove.These hot-blast stoves all are that the energy condition according to the user designs, and they only are fit to use single-fuel, just can only purchase hot-blast stove in addition and reinstall if the user wants to change fuel, have expended a large amount of financial resources and manpower.
The utility model content
The technical problem that utility model will solve: the technical problems to be solved in the utility model provides a kind of dual-purpose hot-blast stove that can coal-fired can fire rice husk again.
The technical scheme that the technical solution problem is taked: a kind of dual-purpose hot-blast stove, the slag remover that comprises expansion chamber, flue and body of heater below in the stove of fuel supply system, body of heater rear end of little arch, the body of heater front end of traveling-grate stoker, the burner hearth inside of flue gas air heat exchanger, the burner hearth bottom of body of heater, body of heater top, described fuel supply system is made of coal fuel supply system and rice hull fuel feedway two parts of being positioned at its top.
As improvement of the present utility model, described rice hull fuel feedway is sent device and is positioned at wind by the wind that rice hull fuel is blown into burner hearth and send the rice husk storehouse on device top to constitute.
As further improvement of the utility model, a mobile little arch that can move forward and backward is housed also on the little arch of described burner hearth inside.
As another kind of improvement the of the present utility model, on the discharging flue of flue gas air heat exchanger, also be provided with an external water-bath expansion chamber.
As another improvement of the present utility model, the slag remover of body of heater below is arranged along expansion chamber, water-bath expansion chamber in traveling-grate stoker, the stove.
Beneficial effect: be provided with coal fuel supply system independently and be positioned at rice hull fuel feedway above it owing to adopted, make hot-blast stove of the present invention can on same hot-blast stove, realize the replacing of coal and two kinds of fuel of rice husk according to user's needs as this technical scheme of fuel supply system of hot-blast stove at the body of heater front end; Owing to adopted the wind that rice hull fuel is blown into burner hearth to send device and be positioned at this technical characterictic of rice hull fuel feedway that rice husk storehouse that wind send device top constitutes, improve the mechanization degree when the utility model hot-blast stove uses rice hull fuel, improved combustion efficiency simultaneously; Because a mobile little arch that can move forward and backward also is housed on the little arch of burner hearth inside, by moving the length that changes arch that moves forward and backward of little arch, in the time of fire coal, move little arch reach, to improve the surface temperature of coal, impel coal to be easy to burning, move after in the time of the combustion rice husk, moving little arch, make the rice husk high-temperature flue gas of conflagration in time discharge, make the utility model when using two kinds of different fuel, can both reach desirable burning and add thermal effect; Owing on the discharging flue of flue gas air heat exchanger, also be provided with a water-bath expansion chamber, make that hot-blast stove fume dust removing effects of the present utility model is better, fume emission is environmental protection more; Owing to adopt the slag remover of body of heater below is arranged along expansion chamber, water-bath expansion chamber in traveling-grate stoker, the stove, made hot-blast stove of the present utility model use the lime-ash that to get rid of expansion chamber and the discharge of external water-bath expansion chamber in traveling-grate stoker, the stove once the cover slag remover simultaneously.
