Abstract
The invention relates to a hot-blast stove for providing hot air for drying equipment 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 casing and a combustion chamber arranged in the stove casing; a cavity between the stove casing and the combustion chamber is an air heating cavity; an air circulating pipeline is fixedly connected to the air heating cavity; a circulating air draft fan is mounted on the air circulating pipeline; a hot air pipeline is fixedly connected to the top of the stove casing; a chimney is fixedly connected to the top of the combustion chamber; an outlet of the chimney penetrates out of the hot air pipeline. According to the hot-blast stove disclosed by the invention, the air circulating pipeline and the circulating air draft fan which are used for recovering heat energy are arranged, so that the heat energy loss can be reduced and the working efficiency also can be improved; besides, high-temperature flue gas generated by combusting fuels in the combustion chamber can be fed into an inner cavity of the drying equipment, so that heat energy can be fully utilized and the air pollution also can be avoided.
Description
Technical field
The present invention relates to a kind ofly for drying equipment provides the hot-blast stove of hot-air, belong 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 reduced 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.
Summary of the invention
The object of the invention is to, 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 solution adopted in the present invention is:
A 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 present invention is provided with for the air circulation duct of energy recovery and circulation air-introduced machine, by circulation air-introduced machine, can will in drying equipment inner chamber, with the air recovery of uniform temperature, deliver in the air heat chamber in hot-blast stove and again be heated, not only can reduce heat-energy losses, can also increase work efficiency; In addition, the high-temperature flue gas that fuel in combustion chamber burning can be produced by chimney is sent in drying equipment inner chamber, can not only make heat energy be fully utilized, and also can avoid causing air pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention when installing and using state.
