Abstract

A hot-blast stove features that its stove body has upper and lower arches, front arch, smoke bridge and grate structure, its heat exchanger has S-shaped smoke tube with cold and hot air inlet and outlet, and its settling chamber is communicated with smoke bridge and connected to smoke tube via smoke cover. The utility model has the advantages of flue gas and air cross heat transfer, the thermal efficiency is high, and the smoking mouth does not have string sulphur phenomenon, clearance and easy maintenance, and the burning is thorough, and the heat is concentrated.

Description

Hot-blast stove

The utility model belongs to the heating stove and accessory, relates to a kind of grain that is, seed, materials such as timber are dried the improvement that thermal source is supplied with stove.

At present, have the electricity consumption high-frequency apparatus that it is dried to the oven dry of grain, seed and timber, also useful dry kiln is dried operation, and these equipment have, and to exist equipment big, and the cost height wastes energy and deficiency such as inconvenient maintenance.

For the deficiency of above-mentioned technology, the purpose of this utility model provides a kind of thermal efficiency height and acts as a fuel the supply hot blast to grain by coal, and seed etc. are as the hot-blast stove of oven dry thermal source.

The technical solution of the utility model is that arch and fire grate up and down are housed in the body of heater, heat exchanger is contained in the burner hearth top, in heat exchanger, smoke pipe is snakelike and links to each other, heat passes through in smoke pipe, and smoke pipe adopts and flexibly connects, fin is equipped with in processing in smoke pipe edge, cold air is gone in the heat exchanger heating through smoke pipe by import to be made cold wind change hot blast into to come out to supply with drying plant through hot-blast outlet and use, it is characterized in that in body of heater, being equipped with face arch, arch, following arch and cigarette bridge and fire grate, the cigarette bridge communicates with expansion chamber, and the top that links to each other with expansion chamber, Yan Gai bottom links to each other with smoke pipe, heat exchanger is contained in above the burner hearth, heat exchanger processing has cool air inlet, and hot-blast outlet and hot-air channel are equipped with in heat exchanger and are snakelike smoke pipe, adopt between smoke pipe to flexibly connect, and be processed with fin at the edge of smoke pipe.

Operation principle of the present utility model is owing to adopt the version of stove baking in the body of heater, makes fuel combustion thorough, and heat is concentrated, and heat uses by the heating of the cold air in the heat exchanger is supplied with drying plant through hot-blast outlet in smoke pipe.Smoke pipe adopts snakelike arrangement and activity to join, and has overcome thermal deformation, and the extension sulphur phenomenon that expansion chamber and Yan Gai join and eliminated smoking port.

Good effect of the present utility model is a thermal efficiency height, and fuel saving is simple in structure, easy to maintenance, is applicable to the oven dry thermal source of materials such as grain, seed, timber.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a cigarette lid front view of the present utility model.

Can know that in Fig. 1 the internal structure that is illustrated in body of heater 1 is by face arch 2, arch 3, under encircle 13, cigarette bridge 11 and fire grate 14 constitute, and heat exchanger 5 is contained in the smoke pipe 6 that snakelike installation is housed above the burner hearth 15 in heat exchanger 5, adopt between the smoke pipe 6 to flexibly connect, and be processed with fin 7 at the edge of smoke pipe 6, be processed with hot-air channel 4 and hot-blast outlet 12 and cold air inlet 8 in heat exchanger 5, expansion chamber 10 and cigarette bridge 11 communicate, and expansion chamber 10 is connected with smoke pipe 6 by cigarette lid 9.

Claims

A kind of hot-blast stove, it is characterized in that:

Face arch 2, arch 3 are housed in body of heater 1, under encircle 13 and cigarette bridge 11 and fire grate 14, cigarette bridge 11 communicates with expansion chamber 10, cigarette covers the top that links to each other with expansion chamber 10,9 bottoms and links to each other with smoke pipe 6, heat exchangers 5 were processed with cool air inlet 8 above heat exchanger 5 was contained in burner hearth 15, hot-blast outlet 12 and hot-air channel 4, and in heat exchanger 5, be equipped with and be snakelike smoke pipe 6, adopt between smoke pipe to flexibly connect, and be processed with fin 7 at the edge of smoke pipe 6.
