summary of the invention:
The purpose of this utility model is to provide a kind of horizontal boiler, and the flue gas pipe fitting of this horizontal boiler is reasonable in design, is conducive to reduce the setting of pipe fitting, simplifies and produces.
The utility model horizontal boiler, is characterized in that: comprise and socket-connecting and the inside and outside column-shaped barrel of horizontal, be provided with the feeding mouth of fuel in interior cylindrical cylindrical shell one end, column-shaped barrel is provided with exhaust opening away from one end of feeding mouth outside, in interior cylindrical cylindrical shell body, be horizontally set with transverse tube, on transverse tube, be placed with four movable grates, fender wall after being positioned in inner barrel that grate rear side is perpendicular and being provided with, be provided with at grate upside tilting the fending off that rear end is connected with rear fender wall, this tilting fending off has the gap in order to ventilation with inner barrel inner top surface, the both sides that are positioned at interior cylindrical barrel outer surface between two cylindrical shells are provided with many first seamless steel pipes that parallel of arranging toward feeding mouth end from inner barrel rear end, second seamless steel pipe of arranging many and paralleling toward inner barrel rear end from feeding mouth end in seamless steel pipe outside portion, wherein first, bottom one of two seamless steel pipes is all higher than grate surface.
Further, on the section of inside and outside column-shaped barrel, the center of circle of each the first seamless steel pipe is positioned on same circumference, and the center of circle of the second seamless steel pipe is positioned in three isocentric circular arc, and the circular arc at the first place, the seamless steel pipe center of circle is concentric with three isocentric circular arc.
Further, above-mentioned tilting fending off is made up of many compact arranged straight pipes, and it is located at the top of horizontally disposed grate obliquely.
Further, described feeding mouth end is provided with airtight front smoke box between two cylindrical shells.
Operation principle of the present utility model: fuel is put into from the feeding mouth of inner barrel one end, be placed on moving grate, along with the burning of fuel, the combustion heat in inner barrel is delivered to the water between inside and outside cylindrical shell by inner barrel wall, heat water, in addition burning produce flue gas by rear fender wall and tilting fend off keep out after, from gap, be discharged to interior cylindrical cylindrical shell rear portion, after the first seamless steel pipe, transport to inner barrel feeding mouth end, after the second seamless steel pipe, be discharged into again the rear side exhaust opening of outer cylinder body.
Because the flue gas after heat amount of burning in inner barrel mainly concentrates on top and the upper lateral part of inner barrel, lower position heat at inner barrel is less, therefore bottom one of first and second seamless steel pipe is also conducive to utilize flue gas heat all higher than grate surface, and can not waste smoke evacuation pipe fitting.

Fig. 2 is profile construction schematic diagram of the present utility model;
Fig. 3 is the A-A profile of Fig. 2;
Fig. 4 is the B-B profile of Fig. 2.
detailed description of the invention:
The utility model horizontal boiler, comprise and socket-connecting and the inside and outside column-shaped barrel of inside and outside column-shaped barrel 1,2(of horizontal is cylindrical tube), the feeding mouth 3 that is provided with fuel in interior cylindrical cylindrical shell 1 one end, column-shaped barrel 2 is provided with exhaust opening 4 away from one end of feeding mouth outside, in interior cylindrical cylindrical shell body, be horizontally set with transverse tube 5, on transverse tube, be placed with four movable grates 6, fender wall 7 after being positioned in inner barrel that grate 6 rear sides are perpendicular and being provided with, be provided with at grate 6 upsides tilting that rear end is connected with rear fender wall and fend off 8, this is tilting fends off and 8 has the gap 9 in order to ventilation with inner barrel inner top surface, the both sides that are positioned at interior cylindrical barrel outer surface between two cylindrical shells are provided with many first seamless steel pipes 10 that parallel of arranging toward feeding mouth end from inner barrel rear end, second seamless steel pipe 11 of arranging many and paralleling from feeding mouth end toward inner barrel rear end in seamless steel pipe outside portion, wherein first, bottom one of two seamless steel pipes is all higher than grate surface.
Further, described feeding mouth end is provided with airtight front smoke box 12 between two cylindrical shells.
Fuel is put into from the feeding mouth of inner barrel one end, be placed on moving grate, along with the burning of fuel, the combustion heat in inner barrel is delivered to the water between inside and outside cylindrical shell by inner barrel wall, heated water, in addition burning produce flue gas by rear fender wall and tilting fend off keep out after, from gap, be discharged to interior cylindrical cylindrical shell rear portion, after the first seamless steel pipe, transport to inner barrel feeding mouth end, after the second seamless steel pipe, be discharged into again the rear side exhaust opening of outer cylinder body.
Because the flue gas after heat amount of burning in inner barrel mainly concentrates on top and the upper lateral part of inner barrel, lower position heat at inner barrel is less, therefore bottom one of first and second seamless steel pipe is also conducive to utilize flue gas heat all higher than grate surface, and can not waste smoke evacuation pipe fitting.The grate of employing activity is conducive to the replacing of grate and the adjustment of position, and is conducive to deashing, adopts fixing whole piece grate to be unfavorable for mobile and deashing.
