Description
Technical field:
The utility model relates to a kind of energy-saving coal hot-air drying stove, particularly changes the heat temperature raising heated-air drying furnace apparatus of light industry raw material.
Background technology:
At present, plain edition hot-blast heater in the prior art, its defective is the heat temperature raising speed height that consumes energy slowly; complex structure; combustion chamber and heat exchange air compartment are provided with two cover systems respectively, and exhaust gases passes mixes to walk with the hot blast air duct, the truce removing slag; the hot blast air themperature is difficult to control; the hot blast air contains flue dust, and the thermal efficiency is low, and is bulky; operation inconvenience, the use cost height.
Summary of the invention:
The purpose of this utility model, provide a kind of energy-saving coal hot-air drying stove, it is to take to collect combustion chamber and heat exchange air compartment formation one, exhaust gases passes and each Tong Qidao of hot blast air duct, heat definitely pollution-free, thermal efficiency height, heat temperature raising speed is fast, hot blast air themperature easily control is adjustable, and the change light industry raw material sanitation and hygiene of heated-air drying reach the purpose of the adjustable drying light industry raw material of energy-saving coal and hot blast air themperature.
The utility model energy-saving coal hot-air drying stove takes following technical scheme to realize, it is to be made of body of heater and burner hearth and fire grate, collection combustion chamber and heat exchange air compartment constitute one, the body of heater upper end is provided with exhaust gases passes and hot blast air duct and dry thing frame, exhaust gases passes and each Tong Qidao of hot blast air duct, the hot blast air-introduced machine is communicated with hot blast air duct and heat exchange air compartment, smoke induced draught fan is communicated with exhaust gases passes and combustion chamber, the body of heater lower end is provided with burner hearth and fire grate and fire door, the body of heater bottom is provided with air inlet and cold wind gate, fire grate and fire door and peep hole are set, the temperature in the cold wind gate control heat exchange air compartment on the burner hearth.Lime-ash is removed under situation about disembarking at any time in the burner hearth, makes the thorough after-flame of coal combustion, reaches the purpose of the adjustable drying light industry raw material of energy-saving coal and hot blast air themperature.
The effect of the utility model energy-saving coal hot-air drying stove is simple in structure, easy to operate, be sparing in the use of coal, exhaust gases passes and each Tong Qidao of hot blast air duct heat pollution-free, thermal efficiency height, quick heating, volume is little, and is easy for installation, time saving and energy saving, be widely used in the heated-air drying furnace apparatus of variousization light industry raw material.
Description of drawings:
The utility model energy-saving coal hot-air drying stove will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the utility model energy-saving coal hot-air drying stove.
