Description

Hot air heating shaping coal stove

The utility model relates to a kind of improvement that can be used for cooking, can utilize again the moulded coal furnace structure of hot blast heating, is a kind of moulded coal hot blast heating multipurpose furnace specifically.

Traditional warming stove is that the thermal efficiency of this kind warming stove is low by body of heater and the direct circumference air of chimney; A kind of hot-water heating stove of development in recent years is the heat carrier with water, and the density contrast that relies on water temperature difference to form water carries out the water circulation, by fin heat is passed to air in the room, again by indoor air convection, improves indoor temperature, reaches the heating purpose.Hot-water heating stove heating system cost height needs periodic maintenance, demands strict technology, and has applied certain difficulty; Rate of warming is slow, especially for the family that After Hours wishes to be rapidly heated and to warm oneself, more can not meet the demands.

The utility model purpose is in order to overcome the shortcoming in the above-mentioned technology, to propose a kind of moulded coal hot blast heating multipurpose furnace, will directly be delivered to indoor raising ambient temperature by the hot-air after the heating of furnace wall, reduce the middle consume of indirect, improving the thermal efficiency.

The utility model purpose is realized by following technical scheme: this kind moulded coal hot blast heating multipurpose furnace, include parts such as burner hearth, furnace lining, ash hole, outlet flue, furnace wall, there is one deck to center on the hotair chamber of furnace wall outside the furnace wall, in the periphery of hotair chamber is heat-insulation layer, an inlet of cold air is arranged in the heat-insulation layer bottom, the cold air that heat-insulation layer is outer communicates with the hotair chamber in the heat-insulation layer, and a hot air outlet is arranged at heat-insulation layer top, and the interior hot-air of heating clamber is communicated with the external world.Can force and two kinds of patterns of nature, send hot blast to the room that needs heating.

The heat that the burner hearth internal combustion is sent, a part is sent from upper furnace, can heat up water or cook, some gives out by furnace lining, furnace wall, heated the indoor air of air heat, heated air flows out from hot air outlet, can be with forcing or flowing naturally, with pipeline hot-air is drained in the room that needs heating, make the very fast intensification in room.Cold air enters from the inlet of cold air of heat-insulation layer bottom constantly that air heat is indoor to be heated, and is flowed out by hot air outlet, so constantly circulation again.

In order to make not too dry of room air, in the hotair chamber bottom, be positioned at and a humidification chamber arranged below the ash hole, in the humidification clear water is housed, the water surface generally is lower than inlet of cold air.When air circulation flowed, the water vapour that evaporates together entered hotair chamber in company with air, and is another indoor with flowing to, and makes with the humid air.And dust in air owing to the gravity reason falls into the water, can be reached the effect that purifies air.Hotair chamber is the space around the furnace wall, can be annular space or square annular space or polygonal annular space.

The utility model has the advantages that rational in infrastructure simple, manufacturing, installation, easy to use, the air that is heated by the furnace wall directly is sent to the room that needs heating, has reduced intermediate heat exchange link, has reduced thermal losses, has improved the thermal efficiency.The user can go into the room that need warm oneself with heated air with for example cheap paper tube drainage of pipeline according to own house situation, also can add clear water in humidification chamber according to different needs, makes room air moistening.Through test, one 15 meters ²When room, 9 ℃ of room temperatures, blowing, room temperature can rise to 17 ℃ after 20 minutes.

Embodiment of accompanying drawings.

Fig. 1 is a moulded coal hot blast heating multipurpose furnace structure chart.

This moulded coal hot blast heating multipurpose furnace includes furnace lining (7), burner hearth (8), ash hole (9), outlet flue (10), furnace wall (1) is the annular that is bent into 3 millimeters thick iron plates, outside the furnace wall, be with an annular hotair chamber (2), thickness is 20 millimeters, what be trapped among the hotair chamber periphery is heat-insulation layer (3), adopt the heat-insulating material perlite, thickness is 20 millimeters, the indoor heat of air heat can not distributed around stove, and drain in the room that to warm oneself along with Hot air quilt.An inlet of cold air (4) is arranged at the heat-insulation layer bottom, indoor cold air enters hotair chamber (2) by inlet of cold air (4), after heating, flow out from the hot air outlet (5) that is positioned at heat-insulation layer top, can hot-air be introduced in the room that will warm oneself with pipeline.In hotair chamber (2) bottom, to be positioned at below the ash hole (9) be humidification chamber (6), in have the humidification clear water, the water surface generally is lower than inlet of cold air.When air entered hotair chamber (5), the water in the humidification chamber (6) evaporated, and was heated the room that the back flows into needs heating in company with air, made with the humid air and purification.

Claims (4)

1, a kind of moulded coal hot blast heating multipurpose furnace, include burner hearth, furnace lining, ash hole, outlet flue, furnace wall, it is characterized in that outside the furnace wall, having one deck to center on the hotair chamber of furnace wall, in the hotair chamber periphery is heat-insulation layer, an inlet of cold air is arranged in the heat-insulation layer bottom, the cold air that heat-insulation layer is outer communicates with hotair chamber, and a hot air outlet is arranged at heat-insulation layer top, and the indoor hot-air of air heat is communicated with the external world.

2, according to the described moulded coal hot blast of claim 1 heating multipurpose furnace, it is characterized in that at hotair chamber the bottom, to be positioned at below the ash hole be humidification chamber, in the humidification clear water is housed, the water surface is lower than inlet of cold air.
