Abstract

The utility model relates to a hot air generating furnace which can cause air to be heated and can discharge the hot air. A furnace liner and a heat absorption pipe are sheathed in the existing furnace mantle. The utility model is a fuel furnace using a blower to supply the air into a furnace chamber for heating and input the heated air into a room for heating or drying the cereal.

Description

Hot-air stove

The utility model relates to a kind of heating installation, especially can produce the hot-air stove of the hot blast that can warm oneself with the burning conventional fuel.

At present, known fuel heating system all is directly to obtain heat or carry out heating with medium transmission heat with combustion fuel.Directly burning heating method can not transmit at a distance and can only warm oneself in the surrounding space to this equipment, the heating equipment that working medium transmits heat can transmit heat at a distance, but indoor intensification is slow, be not suitable for the occasion of quick temperature raising, and device fabrication quality requirement height is difficult for reducing cost.

Since adopt such scheme, the conventional fuel that can directly burn, heat air delivery speed is fast, and indoor temperature is raise fast, and temperature height in the stove, is suitable for the burning of inferior fuel, only adopts the common material manufacturing, and cost is low, and is simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural map of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

Fig. 3 is the endothermic tube structure chart.

Fig. 4 is an endothermic tube B-B cutaway view.

Among the figure 1, furnace shell 2, flue 3, chimney 4, air outlet 5, fire door 6, grate 7, stove seat 8, blast orifice 9, endothermic tube 10, combustion chamber 11, fin

The purpose of this utility model provides a kind of hot-air stove, and it can not only directly add hot-air, and the remote transferring heat energy of energy, uses fuel extensive, is applicable to the heating under the various occasions.

The utility model purpose is achieved in that installs a steel furnace in the steel furnace shell, flue is inserted in the furnace shell and leaves a little space, one circle cast iron endothermic tube is installed in the flue, and the special pipe structure that endothermic tube can be made common garden pipe or have a fin is to increase heat transfer effect.Endothermic tube communicates with the space that furnace shell is formed with inner bag, establishes a blast orifice in the lower end of furnace shell, and an air outlet is designed in the upper end, and blast orifice communicates with space, endothermic tube, air outlet that furnace shell is formed with flue.When fire door adds fuel, fuel combustion produces heat energy and blows into air by air blast from blast orifice, sends occasion until room or required intensification from air outlet after endothermic tube, flue absorb the heat heating.

In Fig. 1, furnace shell (1) is placed on the stove seat (7), flue (2), endothermic tube (9) are housed in the furnace shell (1), there are chimney (3) and air outlet (4) in the upper end, lower end one side is provided with blast orifice (8), wherein, space, endothermic tube (9), the air outlet (4) of blast orifice (8), furnace shell (1) and flue (2) composition communicate and are isolated with combustion chamber (10).Adopt air blast that blast orifice (8) is carried out air blast, air is discharged by air outlet (4) along space and endothermic tube (9) heating back that blast orifice (8) enters furnace shell (1) and flue (2) composition, be transported to indoor raising indoor temperature through utilidor, also can carry out the cereal drying.

In Fig. 2, flue (2) is inserted in the furnace shell (1), endothermic tube (9) is inserted in the flue (2), and the garden that endothermic tube (9) is distributed on flue (2) is on week, and wherein fire door (5) locates not establish suction pipe (9), and grate (6) is housed on the stove seat (7).

In Fig. 3, the design of endothermic tube (9) inboard and the outside has fin (11), with better absorption heat with emit heat.

Claims (6)
