Abstract
The utility model provides a hot blast heater, which comprises a coal intake pipe, a combustion chamber, a baffle wall, a mixing chamber, a feed pipe, dispersing devices, a collecting device, a collecting hopper and a dryer cylinder. The coal intake pipe is arranged at the side surface of the combustion chamber; the feed pipe obliquely extends into the mixing chamber from the top part of the mixing chamber and exposes in the indoor part of the mixing chamber; the outer surface of the feed pipe is paved with a refractory castable with certain thickness; the baffle wall is arranged between the combustion chamber and the mixing chamber; a plurality of dispersing devices are arranged inside the mixing chamber the height of which is properly increased; the collecting device is arranged below the dispersing device and is directly and obliquely connected into the dryer cylinder; and the collecting hopper is arranged at the bottom of the mixing chamber. When drying, the pre-heat stage finishedin the dryer cylinder is moved to be implemented in the mixing chamber of the hot blast heater during the drying process, thus extensively improving the output of the drying system, lightening the working load of the dryer, leading the potential of the system to be sufficiently played and having the advantages of long service life as well as convenient maintenance.
Description
Technical field
The utility model relates to heating plant, particularly a kind of hot-blast stove.
Background technology
At present, in industries such as building materials, chemical industry, for providing the hot-blast stove of thermal source, dryer mainly contains several forms such as manual hot-blast stove, mechanical type hot-blast stove, Coal powder spray formula hot-blast stove, fluidized bed furnace, all form on the whole by combustion chamber and mixing chamber two parts, the major function of its mixing chamber is to prevent that flame combustion chamber from directly entering drier body, and will enter that elevated temperature heat flue gas uneven in temperature mixes in the mixing chamber, treat to enter dryer again after temperature is evenly.But these hot-blast stoves all have a common shortcoming, that is exactly in the process of work, the heat that hot-blast stove produced is directly sent in the drier body mechanically, preheating in the drying materials process, oven dry and dry three phases are all finished in drier body, cause drying system output not high.
The utility model content
The purpose of this utility model is at the defective of several hot-blast stoves in the market, a kind of hot-blast stove is provided, the warm-up phase of finishing in drier body in the drying course is moved in the mixing chamber of hot-blast stove and carry out, dry and dry two stage work and in drier body, only finish, significantly improve dryer output, give full play to system's potential.
The utility model is that the technical scheme that its technical problem of solution is adopted is: comprise coal feeding pipe, combustion chamber, firebreak, mixing chamber, feed pipe, dispersal device, gathering-device, aggregate bin, drier body.
Coal feeding pipe is installed in the side of combustion chamber;
Firebreak is located at the centre of combustion chamber and mixing chamber;
Feed pipe tilts to stretch into mixing chamber from the top of mixing chamber, and it is exposed to the part in the mixing chamber, and the feed pipe outer surface lays certain thickness castable refractory;
At the mixing chamber inside, the feed pipe end that have suitably increased height 4～6 road material dispersal devices are installed, gathering-device is installed in the below of material dispersal device, directly tilts to feed in the drier body, and aggregate bin is in the mixing chamber bottom.
Described dispersal device comprises castable refractory, pre-embedded bolt, heat-resistant, wear-resistant liner plate, beams of concrete.Its main body is the beams of concrete by refractory cement cast, lay certain thickness castable refractory at outer three faces of beams of concrete, and material flow is the inclined-plane through face, and its oblique angle β is greater than the natural angle of repose γ of moist material.Be provided with pre-embedded bolt in the beams of concrete, on the inclined-plane of beams of concrete, the heat-resistant, wear-resistant liner plate is tightly fixed by pre-embedded bolt.
When drying operation, duff enters the combustion chamber by coal feeding pipe, and burning produces heat, makes the atmosphere temperature rising that air blast sends into and becomes hot gas, and hot gas enters mixing chamber by top, combustion chamber under the acting in conjunction of drying system afterbody air-introduced machine and firebreak.Material enters mixing chamber by feed pipe, when material falls through the first road dispersal device, because the angle of inclination beta of heat-resistant, wear-resistant liner plate is greater than the natural angle of repose γ of moist material, material rolls under the self gravitation effect naturally, fall into the next stage dispersal device successively, fall into gathering-device at last, flow into drier body by gathering-device again.Small part is fallen material outside the gathering-device scope and is then taken in automatically in the aggregate bin of mixing chamber bottom and regularly discharge.
When material falls through dispersal device, inclined-plane heat-resistant, wear-resistant liner plate can be given material with the thermal energy transfer that it had, by the gap between two dispersal devices the time, thermal current carries out heat exchange together with material again simultaneously, has so promptly finished the warm in the drying materials operation.
The beneficial effects of the utility model are: can increase substantially drying system output, alleviate the live load of dryer, the potential of system enough be given full play of, long service life, easy to maintenance.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
The utility model embodiment comprises coal feeding pipe 1, combustion chamber 2, firebreak 3, mixing chamber 4, feed pipe 5, dispersal device 6, gathering-device 7, aggregate bin 8, drier body 9.
Feed pipe 5 tilts to stretch into mixing chamber 4 from the top of mixing chamber 4, and it is exposed to the part in the mixing chamber 4, and feed pipe 5 outer surfaces lay certain thickness castable refractory 6-1.
Firebreak 3 is located at the centre of combustion chamber 2 and mixing chamber 4.
In mixing chamber 4 inside that suitably increased height 4～6 road material dispersal devices 6 are installed, gathering-device 7 is installed in the below of material dispersal device 6, directly tilts to feed in the drier body 9, and aggregate bin 8 is in mixing chamber 4 bottoms.
Described dispersal device 6 comprises castable refractory 6-1, pre-embedded bolt 6-2, heat-resistant, wear-resistant liner plate 6-3, beams of concrete 6-4.Its main body is the beams of concrete 6-4 by refractory cement cast, lay certain thickness castable refractory 6-1 at outer three faces of beams of concrete 6-4, and material flow is the inclined-plane through face, and its oblique angle β is greater than the natural angle of repose γ of moist material.Be provided with pre-embedded bolt 6-2 among the beams of concrete 6-4, on the inclined-plane of beams of concrete 6-4, heat-resistant, wear-resistant liner plate 6-3 is tightly fixed by pre-embedded bolt 6-2.
