Abstract

An energy-saving temperature control hot air furnace comprises a fuel hopper, a combustion chamber, rolling grates, heat-conducting fire tubes and an induced draft fan, the horizontal heat-conducting fire tubes are uniformly distributed in a heat-conducting cavity which is arranged above the combustion chamber, a lower smoke box is arranged above the heat-conducting cavity and is divided into a smoke inlet box and a lower smoke transfer box by a lower partition, a smoke tube chamber is arranged above the lower smoke box, smoke guide tubes in vertical arrangement are uniformly distributed in the smoke tube chamber, an upper smoke box is arranged above the smoke guide tubes and divided into an upper smoke transfer box and a smoke outlet box by an upper partition, the induced draft fan is arranged on the smoke outlet box, a hot air box is mounted on the side end of a furnace body, more than two hot air tubes are mounted on the hot air box, one ends of the heat-conducting fire tubes are communicated with the hot air box, the other ends of the heat-conducting fire tubes are connected outside the furnace body, and one end of the smoke tube chamber is communicated with the hot air box while the other end of the same is connected outside the furnace body. The energy-saving temperature control hot air furnace can be directly used to match with a rice processing assembly line, and has the advantages of less energy consumption, long service life and wide application range in the same drying conditions as compared with a traditional hot air furnace.

Description

The energy-saving temperature-control hot-blast stove

Technical field

The utility model relates to a kind of energy-saving temperature-control hot-blast stove.

Background technology

All hot-blast stoves all are the hand burning production of artificial feed in the market, and feed is unstable like this, and furnace temperature is also just unstable, and heat conduction hot blast out is unstable too, and energy consumption is large, service life short.

Summary of the invention

The purpose of this utility model just provides the energy-saving temperature-control hot-blast stove of a kind of less energy consumption, long service life, applied range.

Energy-saving temperature-control hot-blast stove of the present utility model, comprise fuel hopper, the combustion chamber, rolling fire grate, the heat conduction fire tube, air-introduced machine, rolling fire grate is set in the combustion chamber, rolling fire grate is driven by buncher, the top, combustion chamber is thermal conductive cavity, the heat conduction fire tube of uniform horizontal positioned in the thermal conductive cavity, the thermal conductive cavity top is lower smoke box, lower smoke box is divided into into smoke box and lower transfer smoke box two parts by lower clapboard, the lower smoke box top is the smoke pipe chamber, the uniform smoke pipe of leading arranged vertically in smoke pipe chamber, lead the smoke pipe top and be upper smoke box, upper smoke box is divided into upper transfer smoke box and is gone out smoke box two parts by upper spacer, entering the smoke box lower end communicates with thermal conductive cavity, the upper end is communicated with upper transfer smoke box by leading smoke pipe, the upper end of lower transfer smoke box is by leading smoke pipe respectively with upper transfer smoke box with go out smoke box and communicate, go out smoke box and be provided with air-introduced machine, hot bellows is installed in the side of body of heater, plural warm-air pipe is housed on the hot bellows, and an end of warm-air pipe communicates with hot bellows, and heat conduction fire tube one end of horizontal positioned is communicated with hot bellows, outside another termination body of heater, one end of smoke pipe chamber is communicated with hot bellows, outside another termination body of heater, and smoke pipe chamber sealed at both ends in addition.

The operation principle of energy-saving temperature-control hot-blast stove of the present utility model is, combustion chamber internal combustion husk, at first heat the heat conduction fire tube in the thermal conductive cavity, hot flue gas passes thermal conductive cavity to advancing smoke box, enter upper transfer smoke box through leading smoke pipe again, lower transfer smoke box, discharge from the air-introduced machine that goes out smoke box at last, in this process, the heat conduction fire tube of horizontal positioned and the smoke pipe of leading arranged vertically are heated, by entering in the hot bellows after the air heat therebetween, hot blast in the hot bellows can provide thermal source for dryer by the warm-air pipe on it, and a hot-blast stove can be simultaneously to the dryer heat supply below 15.

Energy-saving temperature-control hot-blast stove of the present utility model, characteristics with less energy consumption, long service life, applied range, it can be directly and the dryer on the rice process line support the use, compare with the traditional hot wind furnace, when identical production temperature 500 was spent, this hot-blast stove was discharged flue-gas temperature and is no more than 100 degree, and other hot-blast stoves are discharged flue-gas temperature about 230 degree, this shows energy-conservation about 30%; This hot-blast stove drives rolling fire grate through buncher and rotates, and rolling fire grate automatic uniform band material from fuel hopper enters the stove internal combustion, thereby reaches stable furnace temperature, and the hot blast temperature of deriving is also stablized controlled.
