Description
The utility model relates to a kind of energy efficient hot air furnace, belongs to heating equipment, is specially adapted to the every profession and trade oven dry, also can be used for green house of vegetables and industrial or agricultural, civilian heating.
Hot-blast stove in the past all is with heating steel pipe and steel plate, and conduction is gone to heat cold wind and produced hot blast by metal.No matter vertical or horizontal its volume of this class stove is all very huge, consume great deal of steel, and because the tube bank of most hot-blast stoves all is the version that adopts horizontally set, not only power consumption is high, the thermal efficiency is low, and flexural deformation collapse waist, distortion often appear after being heated, cause the life-span of stove very short, What is more, and not enough unexpectedly 6-8 must change overhaul in individual month.Give installation and transportation because of its huge body weight and bring very big inconvenience, above-mentioned in view of the situation hot-blast stove has further improved necessity.
The purpose of this utility model be to provide a kind of simple in structure, volume is little, in light weight, quick heating, thermal efficiency height, energy savings and great deal of steel, long service life, combined type are convenient to the energy efficient hot air furnace installing, transport and overhaul.
The purpose of this utility model realizes by the following technical solutions, form by stove seat, flue and fan housing, the inner chamber of described stove seat is the combustion chamber, fire grate places the bottom, the flower arch is located at middle part, top, combustion chamber, exocoel is the cold wind preheating cavity, and blast inlet is located at a side of cold wind preheating cavity, and safety valve places the sides adjacent of blast inlet; Flue, fan housing place on the stove seat successively, and the cavity that forms between the inboard of flue and fan housing is the heat radiation chamber, and heat pipe is circumferentially uniform along flue, and the heating end of heat pipe tiltedly puts in the inner chamber of flue, and the flue upper end links to each other with flue tube; Bottom one side of fan housing is provided with hot-blast outlet.
Described heat pipe axially be arranged in parallel from bottom to top along flue, until the flue upper end, is the α angle between its axis and flue axis, and the α angle is the 30-45 degree.
Circumferentially having eight branch air ports with the corresponding side of fire door edge on the flange of described stove seat.
Both sides at flue between described fan housing and the flue are arranged with wind isolation board from bottom to top, and extend to the shoulder position of contracting, flue top.
Described safety valve, it comprises the half of down inside and outside cover that all has ventilating opening, and wherein overcoat is fixed, and interior cover can rotate with respect to overcoat, with the opening and closing of fault ventilating opening, the end face of cover in explosion-proof film places.
The utility model compared with prior art, owing to what adopted that structure similar to boiler and mode of heating adorn is heat pipe, with the chemical working medium in it is carrier, under the driving of thermal source, make working medium gasification produce high-energy physics and change, cause rapid intensification, conduction of velocity is fast and be knockdown structure.So there is long-pending corpusculum light, overhaul advantages such as convenient than 10 tons of steel of same specification stove saving, 50% energy, thermal efficiency height, long service life, transportation, installation, implement simultaneously to be beneficial to and to apply easily.

Fig. 2 is an A-A cross section structure schematic diagram.
Fig. 3 is the plan structure schematic diagram of safety valve.
Fig. 4 is the main TV structure schematic diagram of safety valve.
Fig. 5 is the side-looking structural representation of safety valve.
Fig. 6 is a B-B cross section structure schematic diagram.
Embodiment of the present utility model is described in conjunction with the accompanying drawings, stove seat 1 is through the welding processing moulding by steel plate, its inner chamber is the combustion chamber, fire grate 2 places bottom, flower arch 14 to be located at middle part, top, combustion chamber, exocoel is the cold wind preheating cavity, blast inlet 15 is located at a side of cold wind preheating cavity, and safety valve 5 is located at the sides adjacent of blast inlet 15; Fire door 3 is at opposite side; Flue 6, fan housing 7 place on the stove seat 1 successively, the cavity that forms between the inboard of flue 6 and fan housing 7 is heat radiation chamber 11, heat pipe 12 is circumferentially uniform along flue 6, be arranged in parallel from bottom to top vertically, and be the α angle with flue 6 axis, the α angle is the 30-45 degree, the heating end of hot rainbow formula heat pipe 12 tiltedly puts in the inner chamber of flue 6 by pipe box 10, the upper end of flue 6 links to each other with flue tube 9, be arranged with wind isolation board 8 from bottom to top in the both sides of flue 6 between fan housing 7 and the flue 6 and extend to the shoulder position of contracting, flue 6 tops, hot-blast outlet 13 is located at fan housing 7 bottoms one side.Three layers of pipe box 10 are for sealing sleeve pipe with the protection heat pipe from bottom to top; Eight branch air ports 4 are located at stove seat 1 upper flange and fire door 3 corresponding sides along last.Described safety valve 5 comprises interior overcoat 18,17, all have ventilating opening 20,19 in its Lower Half separately, wherein overcoat 17 is fixing, and interior cover 18 can rotate with respect to overcoat 17, with opening and closing of fault ventilating opening 19,20, the end face of cover 18 in explosion-proof film 16 places.
When the utility model uses; checking routinely under all normal conditions; start air blast earlier; and open the safety-valve 5 so that clear up a lower hearth and flue 6; closed safe valve 5 is promptly removed being in upper-lower position; point stove and starting air blast are carried out simultaneously; at this moment can start random according to combustion case; can burn control and balance outlet temperature with hand according to hot blast temperature after operation is normal; the burning that can go round and begin again behind the temperature stabilization is gone down; until blowing out; open the safety-valve 5 once more with protection heat pipe 12; do not turn off the blast immediately simultaneously after the blowing out; treat to close again when outlet temperature is reduced to 50 ℃ air blast; can reconcile with safety valve 5 when lowering the temperature rapidly as need; burning is to carry out in the combustion chamber; flame rises by convection current flower arch 14; the heating end of heat hot nest of tubes; by the chemical working medium in it heat is passed to heat radiation chamber 11 rapidly, main blower is sent the cold wind preheating cavity of cold air from air inlet 15 injection stove seats 1 into a side in heat radiation chamber 11 through eight branch air ports 4; walk around wind isolation board 8 from the top and change opposite side over to; deliver to drying chamber from heat radiation chamber 11 lower end hot-blast outlets 13, when its outlet temperature was higher than 150 ℃, available safety valve 5 was turned down the temperature in the flue 6.If when in running, having a power failure, can open the ventilating opening 19,20 of safety valve 5 immediately so that clearing furnace, flue prevent gatherings such as carbon monoxide; in case do not have row thoroughly; when the burner hearth supercharging surpasses limits value, the at first explosion pressure release of explosion-proof film 16, thus protected equipment.
