Description

Hot-blast stove

Affiliated technical field

The utility model belongs to a kind of warming stove, a kind of specifically warming stove that warm braw is provided.

Background technology

In the prior art, State Intellectual Property Office authorizes on June 18th, 2008 and discloses announcement and number be: the utility model patent of CN201074900Y " civil version hot-blast stove ", this patent comprises body of heater and inner flue thereof, smoke exhaust pipe is arranged at flue top, the outside is covered with the warm braw pipe, one end of warm braw pipe links to each other with fan, and other end air outlet is positioned at outside the body of heater.Coal burns in flue, and heat energy is directly passed to flue, passes to the warm braw pipe then.Fan outside body of heater, reaches the purpose of heating with the heat delivery in the warm braw pipe.The deficiency of its existence is: smoke exhaust pipe is arranged at flue top, and the cigarette of high heat directly is discharged to outside the stove, has wasted a lot of heat energy.Therefore, its thermal efficiency is low, and result of use is poor.

Summary of the invention

The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved hot-blast stove is provided, and its compact conformation is reasonable, can make full use of the body of heater heat, thermal efficiency height, and result of use is good.

For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: body of heater shell, flue, blower fan, in the flue is the combustion chamber, the bottom is provided with fire grate, the upper end is provided with fire door, between flue and body of heater shell, be provided with the warm braw chamber, it is characterized in that: the upper fixed at fire door is connected with horizontally disposed flue, be provided with several smoke evacuation boxes in the flue, be provided with the wind chamber between the smoke evacuation box, establish smoke chamber in the smoke evacuation box, an end smoke chamber of smoke evacuation box is communicated with fire door, the other end is positioned at the place, outer end of flue, and is communicated with chimney; Be provided with wind chamber partition panel in the flue, the external blower fan in wind chamber of flue outer end also is communicated with the warm braw chamber, and the external exhaust outlet in wind chamber of flue inner end also is communicated with the warm braw chamber.

The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, the fuel that ignition combustion is indoor, the warm braw chamber in the heat transferred outside of flue, the high temperature at fire door place and smoke exhaust heat enter into the smoke chamber of smoke evacuation box, then with the wind chamber outside the heat transferred.Blower fan work, distinguished and admirable wind chamber along the flue outer end enters into the warm braw chamber, then, enters in the wind chamber of flue inner end again, discharges from exhaust outlet at last.Like this, the utility model has made full use of the heat of flue, has improved the thermal efficiency greatly, and heating effect is good.
