Description
Technical field
The utility model belongs to the drying unit technical field, is specifically related to a kind of hot-blast stove.
Background technology
Existing hot-blast stove mainly is to adopt in drum type brake body of heater bottom the combustion chamber is set, and vertical heat exchanger is set in the upper chamber, and top connects air outlet, combustion chambers burn fuel heating heat exchanger, air outlet output in the wind.Because furnace chamber is straight barrel type, directly goes out from air outlet from the gas that air inlet is come in, the limited time of gas in furnace chamber can not be heated fully, and the hot blast temperature adjustable range is little, and energy utilization rate is not high.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to design the technical scheme that a kind of hot-blast stove is provided.
Described a kind of hot-blast stove, comprise body of heater, it is characterized in that arranging in the described body of heater exhaust gases passes and air duct, described exhaust gases passes comprises burner hearth, the flue that communicates with roof of the furnace, the exhaust opening that communicates with flue, described air duct comprises air inlet, be arranged on outer space air flue that the flue outside communicates with air inlet, be arranged on the jet band that communicates with air flue top, outer space between burner hearth and the flue reaches the air outlet that communicates with the jet band, on the above-mentioned exhaust opening air-introduced machine is set, on the above-mentioned air inlet main air blower is set.
Described a kind of hot-blast stove is characterized in that described burner hearth lower end is provided with the burning fire door.
Described a kind of hot-blast stove is characterized in that described exhaust opening is arranged on the flue lower end.
Described a kind of hot-blast stove is characterized in that described jet band encloses structure by jet plate and form, and described jet plate is provided with spurt hole, and described spurt hole diameter is 4.6～6mm.
Above-mentioned a kind of hot-blast stove, simple in structure, reasonable in design, air and flue gas carry out heat exchange at air duct and exhaust gases passes by reflux type, and under the pressure effect of main air blower, air enters body of heater from bottom to top, enter the jet band then again from top to bottom, carry out injection heat transfer, thereby reach required hot blast temperature, discharged to enter by air outlet and carry out drying in the dryer.The utility model provides hot-air for the oven dry of various materials, and the thermal efficiency reaches more than 70%, heats up rapidly, and contaminated material does not use convenient and reliable operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Among the figure: the 1-burner hearth; 2-burns fire door; The 3-exhaust opening; The 4-flue; 5-outer space air flue; The 6-jet band; The 7-air outlet; The 8-main air blower; The 9-air-introduced machine.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of hot-blast stove comprises body of heater, and exhaust gases passes and air duct are set in the body of heater, and exhaust gases passes is used for logical flue gas, and air duct is used for logical cold air, and flue gas and cold air carry out heat exchange in body of heater.
Exhaust gases passes comprises burner hearth 1, the flue 4 that communicates with burner hearth 1 top, the exhaust opening 3 that communicates with flue 4, and exhaust opening 3 is arranged on flue 4 lower ends, and air-introduced machine 9 is set on the exhaust opening 3.Burner hearth 1 lower end also is provided with burns fire door 2, is used for fuel is sent in the burner hearth 1.Under the effect of air-introduced machine 9, flue gas enters burner hearth 1 from bottom to top, enters flue 4 then again from bottom to top, discharges from exhaust opening 3 at last.
Air duct comprises air inlet, be arranged on outer space air flue 5 that flue 4 outsides communicate with air inlet, be arranged on the jet band 6 that communicates with outer space air flue 5 tops between burner hearth 1 and the flue 4 and the air outlet 7 that communicates with jet band 6, air outlet 7 is arranged on 6 lower ends, jet band, and main air blower 8 is set on the air inlet.Under the effect of main air blower 8, air enters outer space air flue 5 from bottom to top, enters jet band 6 then again from top to bottom, carries out injection heat transfer, thereby reaches required hot blast temperature, is discharged to enter by air outlet 7 at last and carries out drying in the dryer.Jet band 6 is enclosed structure by jet plate and is formed, and described jet plate is provided with spurt hole, and described spurt hole diameter is 4.6～6mm.The effect of jet band 6 is to improve wind speed.
In the utility model since air and flue gas separate, thereby guaranteed dry air totally; Fresh cold air enters first preheating through the stove outer ring earlier, thereby has avoided too much the scattering and disappearing of heat.
Shown in the above and the figure only is preferred embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
