Abstract
The utility model relates to a hot-blast stove providing hot air for a drying device, and belongs to the technical field of heat supply equipment. The hot-blast stove comprises a stove body, wherein the stove body comprises a stove shell and a combustion chamber arranged in the stove shell, a cavity between the stove outer shell and the combustion chamber is an air heating cavity, the air heating cavity is fixedly connected with an air circulating pipeline, and a circulating induced draft fan is arranged on the air circulating pipeline. The top of the stove shell is fixedly connected with a hot air pipeline, a chimney is fixedly connected with the top of the combustion chamber, and an outlet of the chimney penetrates out of the hot air pipeline. The hot-blast stove is provided with the air circulating pipeline and the circulating induced draft fan for heat energy recycling, the heat energy losses can be reduced, and working efficiency can be improved. In addition, high-temperature smoke generated by combustion of fuel in the combustion chamber can be fed into the inner cavity of the drying equipment through the chimney, the heat energy can be fully utilized, and air pollution is avoided.
Description
Technical field
The utility model relates to a kind of for drying equipment provides the hot-blast stove of hot-air, belongs to heating equipment technical field.
Background technology
In sheet material process of manufacture, sheet material need to be dried, by hot air dries, the moisture in sheet material is evaporated, make the moisture content of sheet material be down to the level suitable with local equilibrium moisture content, thereby avoid that sheet material goes mouldy, splitting, distortion.Existing panel drying device, normally utilize hot-blast stove to provide hot-air to carry out bake drying to sheet material, but because existing hot-blast stove does not possess heat-recovering function, not only caused the waste of heat energy, also reduce operating efficiency, made the dry uniformity of sheet material poor.In addition, the high-temperature flue gas producing in hot-blast stove fuel combustion is also all gone out from smoke stack emission, not only causes heat-energy losses, also can cause atmosphere pollution.
Utility model content
The purpose of this utility model is, a kind of hot-blast stove of energy-conserving and environment-protective is provided, to solve above-mentioned technical problem.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of hot-blast stove, comprises body of heater, and the bottom of described body of heater is provided with fire door, and fire door is installed on fire door, is provided with fire grate in body of heater, and the below of described fire grate is provided with ash-falling chamber; It is characterized in that: described body of heater comprises stove outer covering and be located at the combustion chamber in stove outer covering, and the cavity between described stove outer covering and combustion chamber is air heat chamber; Described fire door runs through stove outer covering, air heat chamber successively, and is connected with combustion chamber, and described fire grate is fixed on the bottom of combustion chamber; Described air heat chamber is fixedly connected with air circulation duct, and circulation air-introduced machine is installed in described air circulation duct; The top of described stove outer covering is fixedly connected with hot-air duct; The top of described combustion chamber is fixedly connected with chimney, and the outlet of described chimney passes hot-air duct.
Say further, the position that the top of described combustion chamber and chimney join is provided with the fireguard of level, and the surrounding of described fireguard is provided with cigarette gap.
Beneficial effect: compared with prior art, the utility model is provided with for the air circulation duct of energy recovery and circulation air-introduced machine, air with uniform temperature in drying equipment inner chamber can be reclaimed in the air heat chamber of delivering in hot-blast stove and again heated by circulation air-introduced machine, not only can reduce heat-energy losses, can also increase work efficiency; In addition, send in drying equipment inner chamber by the chimney high-temperature flue gas producing that fuel in combustion chamber can be burnt, can not only make heat energy be fully utilized, also can avoid causing air pollution.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model in the time installing and using state.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, hot-blast stove described in the utility model, comprises body of heater, and the bottom of described body of heater is provided with fire door 2, and fire door 1 is installed on fire door 2, is provided with fire grate 18 in body of heater, and the below of described fire grate 18 is provided with ash-falling chamber 17.Described body of heater comprises stove outer covering 3 and is located at the combustion chamber 5 in stove outer covering 3, and the cavity between described stove outer covering 3 and combustion chamber 5 is air heat chamber 4; Described fire door 2 runs through stove outer covering 3, air heat chamber 4 successively, and is connected with combustion chamber 5, and described fire grate 18 is fixed on the bottom of combustion chamber 5.
