Abstract

The utility model discloses a do not need purification treatment just can produce clean hot -blast and hot -air furnace that can reduction in production cost, including firing burning furnace, fire and be equipped with furnace in the burning furnace, furnace outside sealing connection has the air heating room, is equipped with cold wind import, hot air exitus on the air heating room. Be equipped with hot -blast heating pipe in the furnace, hot -blast heating pipe both ends and air heating room intercommunication. The indoor spiral plate that is equipped with of air heating. After separating the air heating room, the spiral plate forms a heliciform airflow channel, heliciform airflow channel upper end and cold wind import intercommunication, hot air exitus and heliciform airflow channel lower extreme intercommunication. Spiral plate crisscross distribution about air heating is indoor sets up.

Description

A kind of hot-blast stove

Technical field

The utility model relates to air heating apparatus, particularly a kind of hot-blast stove.

Background technology

In normal activity in production, need to utilize clean hot blast to dry product to be processed or drying, such as: in the production of chemicals, chemical products and medicine, utilize hot-air drying technology, cultivation, greenhouse, stroke snow pack hall etc. need to warm oneself with hot blast, emery cloth and emery wheel production process need, with hot-air seasoning, also to need to utilize hot blast to carry out drying in the production processes such as coffee, tealeaves, tobacco leaf and vegetables, cereal, vermicelli, aquatic products, fish meal, dregs of beans.By long production practices, it has been recognized that to only have and utilize hot blast could improve efficiency of utilization larger as medium and carrier.Traditional electric heat source and steam source often need configuration multiple stage circulating fan in course of conveying, and after making it final or indirect formation hot blast, reciprocity converted products carries out drying or drying again.This production process needs to waste a large amount of energy, also there is the shortcomings such as auxiliary device is too much, complex technical process.Also have the high-temperature flue gas utilized as the combustible materials such as coal, carbon, timber, stalk, saw foam produce after hot-blast stove combustion, the hot blast that high-temperature flue gas is formed after purified treatment is dried product to be processed or drying; Because high-temperature flue gas needs purified treatment, directly can not dry product to be processed or drying, add production cost, reduce profit margin.

Summary of the invention

The technical problem that the utility model solves is to provide and does not a kind ofly need purified treatment just can produce clean hot blast and can reduce the hot-blast stove of production cost.

The utility model scheme is done in such a way that a kind of hot-blast stove, includes combustion furnace, is provided with burner hearth in combustion furnace, is sealedly connected with hotair chamber outside burner hearth, and hotair chamber is provided with cold wind import, hot-blast outlet.

Further preferred embodiment, is provided with Hot-blast Heating pipe in described burner hearth, Hot-blast Heating pipe two ends are communicated with hotair chamber.

Further preferred embodiment, described air heat indoor are provided with spiral plate.

Further preferred embodiment, spiral plate is interspersed up and down in air heat indoor setting.

Further preferred embodiment, described spiral plate forms a helical airflow passage after being separated by hotair chamber, and helical airflow passage upper end and cold wind inlet communication, hot-blast outlet is communicated with helical airflow passage lower end.

The heat that the burnings such as the coal in burner hearth, carbon, timber, stalk, saw foam produce can be directly passed to the cleaned air entering air heat indoor by the utility model by hearth wall, air is heated product Direct Contact Heating drying rear and to be dried or is toasted, eliminate purification of air flow process, effectively reduce production cost.In addition, the utility model can use the fuel such as coal, carbon, timber, stalk, saw foam, compared with use natural gas, electric equal energy source, effectively can reduce production cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

By reference to the accompanying drawings the utility model is described in further detail, grate 2 is provided with below burner hearth 3 of the present utility model, grate 2 is provided with slag room 1 below, the right side of slag room 1 is provided with the clean-up port 11 of cleaning slag, charge door 10 is located at above grate 2, bottom burner hearth 3, be sealedly connected with hotair chamber 7 outside burner hearth 3, the inwall of hotair chamber 7 is exactly the outer wall of burner hearth 3; Hotair chamber 7 top has cold wind import 8, and hot blast outlet 4 is located at bottom hotair chamber 7, and the chimney 9 be located at above burner hearth 3 passes hotair chamber 7 and is tightly connected with hotair chamber 7.

Further preferred embodiment, for improving the air heat absorption efficiency in hotair chamber 7, run through in burner hearth 3 and have Hot-blast Heating pipe 6, Hot-blast Heating pipe 6 two ends are communicated with hotair chamber 7.

Further preferred embodiment, spiral plate 5 is welded with in hotair chamber 7, hotair chamber 7 is separated rear formation helical airflow passage by spiral plate 5, helical airflow passage upper end is communicated with cold wind import 8, hot-blast outlet 4 is communicated with helical airflow passage lower end, because the helical airflow passage set up extends the time of staying of air in hotair chamber 7, equal to add the air heat time, make the more heat of the absorption of air in hotair chamber 7, contribute to Quick high air temperature.Also can be interspersed spiral plate 5 in air heat indoor setting up and down, and the spiral plate 5 be interspersed can change air-flow direction, thus contribute to improving rate of heat exchange.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, also should be considered as protection domain of the present utility model.

Hothouse or bakery is entered into after the high-temperature gas that the utility model produces can be mixed into a certain temperature with outside air further, also hothouse or bakery can directly be entered, contact with processed product, processed product by after heating evaporation moisture, the product required for acquisition.The utility model is mainly applicable to dried material and does not allow contaminated, or it is dry to be applied to the lower heat sensitive material of temperature.As: milk powder, pharmacy, synthetic resin, fine chemistry industry etc.
