Abstract

The utility model relates to a hot blast stove mainly for vegetable greenhouse heating and an air supply and exhaustion device; wherein, an interlayer is designed between a furnace body and an internal furnace, and also is designed in a preheating chamber; a spiral deflector is arranged in the interlayer; the interlayer is also designed at the top of the furnace, which can make the hot blast advance orderly in the interlayer, so as to increase the heating surface and heating time and raise the heating temperature. The grate is arched, and is provided with a vibrator, which can make the grate vibrate at high frequency and low amplitude, so as to achieve automatic ash peeling and discharging. An umbrella valve is arranged at the bottom part of the furnace body, and the fuel combustion is in a semi-dormant state when the umbrella valve is closed. A combustion supporting hot blast pipe is arranged at the lower part of the furnace body, which can supply hot blast for the grate, so as to quickly raise the furnace temperature. A distributing valve is arranged at the upper part of the furnace, which can supply air for the secondary combustion at the top part of the hearth. The connecting pipe of the air duct and the flue has a pipe-in-pipe structure, and the excess heat in the smoke flue can be completely absorbed by the air duct. In addition, a plurality of exhaustion openings used for hot blast discharge are arranged on the connecting pipe of the air duct. The utility model has an advantage of being a new environment protection, clean, labor-saving and energy-saving central heating device for vegetable greenhouse.

Description

Hot-blast stove and confession exhaust equipment thereof

The utility model is a kind of hot-blast stove and confession exhaust equipment thereof that is mainly the green house of vegetables heating.

A hundred leagues locked in ice in the north in winter, Wan Lixue wafts, and Chinese pearleaf crabapple leaf is green in the green house of vegetables, Spring is very much in the air, and this all be unable to do without heating equipment.Now, the green house of vegetables heating equipment of rural area majority all is brick stove or the heat radiation of iron-clad stove gas-fired direct burning.Hundred meters booths need be pacified seven or eight stoves, and a fireman is very busy round the clock, and a winter will be burnt more than ten ton of coal, and in the canopy by stove near roasting, from stove cold far away, make crop uneven in temperature, growing way is irregular, must be subjected to the gas of flue dust, to making its output and quality all influenced ...

For overcoming the above-mentioned defective of prior art, the utility model aims to provide a kind of hot-blast stove and for exhaust equipment, is mainly used in the central heating of green house of vegetables, and not only heat supply is even, and it is laborsaving to economize on coal, and still can increase substantially output and the quality of crop.

For achieving the above object, the utility model mainly is made of body of heater, flue, flow deflector, fire grate, vibrator, umbrella valve, blower fan, preheating chamber, ventilating duct, flue connecting tube, air channel connecting tube and air draft mouth etc.Reach preheating chamber between body of heater and flue and all be designed to interlayer, the helical form flow deflector is housed in the interlayer, furnace roof also is designed to interlayer, and these can make hot blast advance in order in interlayer, increase heating surface and heated time, improve heating temperature.Fire grate is an arch, and vibrator is housed on it, and vibrator work 2-3 can make the fire grate high frequency vibrate by a narrow margin second, forms the stripping type automatic removing dust.Bottom of furnace body is equipped with umbrella valve, and control combustion-supporting chamber is a fire grate nature air feed.Close umbrella valve, can make the fuel combustion on the fire grate be in the semidormancy state.Be provided with combustion-supporting warm-air pipe in the body of heater bottom, open valve on it, can be the fire grate hot wind supply, quicken fuel combustion, improve furnace temperature fast.On the flue cover of the top of stove, distributing valve is housed, can be the pyrotechnics second-time burning air feed of roof of the furnace.Flue cover and upper of furnace body constitute circuitous channel, and pyrotechnics is top interlayer heat supply by circuitous the advancing of this passage.The connecting tube of air channel and flue is a tube-in-tube, the one, be convenient to install, and the 2nd, the waste heat in the flue can fully be absorbed by the hot blast in the air channel.In the connecting tube of air channel, be provided with several air draft mouths, for thermal wind exhausting is used.

Owing to take above-mentioned technical solution, the utlity model has compact conformation, take up an area of little, advantages such as hot blast rate big, even, the energy-conservation source of heat radiation, human-saving, the real environmentally-friendly sanitary a new generation central heating facility that belongs to green house of vegetables.
