Coal-fired hot-blast stove is the coal furnace that hot blast can be provided.In the prior art, Chinese patent 2,008 2 0220360.2 discloses a kind of fin type hot-air stove, it is vertical fin coal-fired hot-blast stove, vertical fin coal-fired hot-blast stove has the vertical and cylindrical body of heater, the body of heater cylinder has the cylindrical shape chuck outward, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ash hole is arranged, there is exhaust opening the upper end of body of heater, handlebar cylindrical shape chuck is divided in the cylindrical shape chuck, the annular dividing plate of following two air compartments, air intake vent is arranged at the bottom of lower air chamber, and air outlet is arranged at the bottom of ipper air chamber, be evenly equipped with the airduct parallel with the body of heater axis in the burner hearth, the upper end of airduct links to each other with the top of ipper air chamber, and the lower end of airduct links to each other with the top of lower air chamber, and the body of heater cylinder outer wall face in chuck has fin.Fin is along the parallel steel plate bar of the uniform axis with the body of heater cylinder of body of heater cylinder excircle.
In the cylindrical shape chuck of vertical fin coal-fired hot-blast stove, handlebar cylindrical shape chuck is divided into, the annular dividing plate of following two air compartments, the outer shroud week of annular baffle is connected on the inner peripheral wall of cylindrical shape chuck, being connected on the outer circle wall of body of heater cylinder in interior ring week of annular baffle, during use, send into normal temperature air with blower fan from air intake vent, normal temperature air is successively through lower air chamber, discharge from air outlet after airduct and the ipper air chamber, add fuel in from fire door to burner hearth, fuel burns above fire grate, the heat that produces adds warm-air pipe and chuck, makes through lower air chamber, the normal temperature air of airduct and ipper air chamber is heated to form hot blast, and hot blast is discharged from air outlet and used.The inlet air flow path of this vertical fin coal-fired hot-blast stove is very long, very tortuous, and the resistance that air flows is bigger; The fin of body of heater cylinder excircle is along the parallel steel plate bar of the uniform axis with the body of heater cylinder of body of heater cylinder excircle, the steel plate bar parallel along the uniform axis with the body of heater cylinder of body of heater cylinder excircle forms uniform straight flute at body of heater cylinder excircle, when air is flowed through the above-mentioned body of heater cylinder excircle that fin arranged, be in straight flute, not change direction ground to flow, be evenly distributed along body of heater cylinder excircle in the time of can not guaranteeing that air flows through from chuck, the thermal efficiency is not very high.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the vertical wing coal-fired hot-blast stove that revolves that resistance is less, the thermal efficiency is higher that a kind of air flows.
The utility model is realized with the following method.
The vertical wing coal-fired hot-blast stove that revolves has the vertical and cylindrical body of heater, the body of heater cylinder has the cylindrical shape chuck outward, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ash hole is arranged, there is exhaust opening the upper end of body of heater, handlebar cylindrical shape chuck is divided in the cylindrical shape chuck, the annular baffle of following two air compartments, air intake vent is arranged at the bottom of lower air chamber, be evenly equipped with the airduct parallel with the body of heater axis in the burner hearth, the lower end of airduct links to each other with the top of lower air chamber, the upper end of airduct links to each other with the top of ipper air chamber, body of heater cylinder outer circle wall in chuck has fin, the be in the wind top of chamber of air outlet, the outer shroud week of annular baffle is connected on the inner peripheral wall of cylindrical shape chuck, between the interior ring week of annular baffle and the outer circle wall of body of heater cylinder the loop vent gap is arranged, and the fin on the body of heater cylinder outer circle wall is that the steel plate bar is trapped among the spirality fin on the body of heater cylinder outer circle wall.
On the inner peripheral wall that is connected in the cylindrical shape chuck outer shroud week of the annular baffle in the chuck of the present utility model, between the outer circle wall of interior ring week and body of heater cylinder the loop vent gap is arranged, the normal temperature air of sending into from air intake vent with blower fan is divided into two-way in chuck lower air chamber, one the tunnel discharges from air outlet behind airduct, discharge from air outlet after chuck ipper air chamber on another road, inlet air flow path is not long, not tortuous, and the resistance that air flows is less; The spirality fin is at body of heater cylinder outer circumferential spirality groove.The air that enters in the chuck ipper air chamber is to flow along body of heater cylinder excircle in the helical fin groove, air constantly changes flow direction when body of heater cylinder excircle flows in the helical fin groove, when being flow through from chuck, air is evenly distributed along body of heater cylinder excircle, in addition, flow velocity and less turbulence were higher when air was mobile along body of heater cylinder excircle in the helical fin groove, were conducive to improve the film coefficient of heat transfer.
