Abstract

The utility model relates to a vertical full-automatic multipurpose oil burning boiler, comprising a boiler shell 9, a boiler container 4, a smoke pipe 6, an upper pipe plate 10, a lower pipe plate 5, a punching sealing head 13, an oil boiler controller 15, a water inlet pipe 3, a water outlet pipe 16, an air exhaust hole 12, a heat-insulating layer 2, a fire viewing hole 17 and a burner 18. The smoke pipe 6 is a screw thread type screw thread smoke pipe. The boiler container 4 is changed from the high-cavity boiler container into the low-cavity boiler container. The smoke pipe 6 is changed from the high side wall fillet weld into the low side wall fillet weld. The utility model has the advantages that the heat efficiency reaches to 92.1%; the service life is long; the working boiler age can extend 1-2 years.

Description

Vertical fully automatic multipurpose oil burning boiler

The utility model relates to boiler, especially a kind of vertical fully automatic multipurpose oil burning boiler that is threaded smoke pipe.

Be used to drink water, have a bath, the boiler of heating is varied, vertical oil burning boiler is wherein a kind of.Present two problems of vertical oil burning boiler ubiquity of using, the one, because of stressing to consider the compactness of structure and the size of exerting oneself, cause the thermal efficiency on the low side, fuel consumption is big, wastes energy.The 2nd, the upper and lower tube sheet long-term work at smoke pipe two ends the hole often occurs and squeezes cracking under abominable hot environment.Last lower perforated plate is directly connected to the safe operation and the service life of boiler in case cracking can't recover substantially.

The purpose of this utility model is that the thermal efficiency that exists of the vertical oil burning boiler at present use is low, fuel consumption big, go up lower perforated plate problem easy to crack, a kind of simple structure is provided, compact conformation, easy to operate, thermal efficiency height, oil consumption is few, cigarette, gas, the vertical fully automatic multipurpose oil burning boiler that the dirt emission index is low.

The utility model is achieved in that vertical fully automatic multipurpose oil burning boiler comprises shell, flue, smoke pipe, upper perforated plate, lower perforated plate, punching end socket, oil oven controller and water inlet pipe, outlet pipe, steam vent.The flue bottom is provided with thermal insulation layer.The flue side is equipped with and is looked fire hole and burner.Furnace shell outside is surrounded by rock wool and with stainless steel sheet| with bind round up and down and wrap.Said smoke pipe is the threaded flue of screw-type.Flue changes low chamber flue into by the high pitched tune flue, and when flue wall of inner container diameter was 430MM, the height of flue was reduced to 330-360MM by 390MM.The height that smoke pipe stretches out upper and lower tube sheet changes the low sidewall filled weld into by high sidewall filled weld, promptly reduces to 4-6MM by 10-15MM,

Used oil oven controller and burner all can adopt the commercially available prod, produce Y2-6 type oil oven controller and Italy product BT14GW type burner as Radio Factory of Tianjin Univ..

The utility model changes the light smoke pipe in the former vertical oil burning boiler into threaded flue, increased the flue gas stroke, increased heat exchange area, change the high pitched tune flue into low chamber flue and not only strengthened smoke pipe length, increase heat exchange area, strengthened, accelerated the combustion gas whirling motion in the combustion chamber simultaneously, the abundant burning of favourable combustion gas.By improvement, make the thermal efficiency of boiler be increased to 92.1% to smoke pipe and flue.The low sidewall filled weld is adopted in the welding of smoke pipe and upper and lower tube sheet, has reduced the thermal stress that the smoke pipe welding ends causes, has improved the tube sheet life-span.Threaded flue has reduced the rigidity of body, has increased elasticity, has improved the condition of work of upper and lower tube sheet, has improved the tube sheet life-span.Smoke pipe and upper and lower tube sheet adopt the low sidewall filled weld and adopt threaded flue, make the work furnace life prolongation 1-2 of boiler.

Fig. 1 is a structural map of the present utility model;

Fig. 2 is the partial enlarged drawing of threaded flue;

Fig. 3 is the structure chart that traditional vertical oil burning boiler smoke pipe and tube sheet adopt high sidewall filled weld;

Fig. 4 is the structure chart that the utility model smoke pipe and tube sheet adopt the low sidewall filled weld.

The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1, vertical fully automatic multipurpose oil burning boiler comprises shell 9, flue 4, smoke pipe 6, upper perforated plate 10, lower perforated plate 5, punching end socket 13, oil oven controller 15 and water inlet pipe 3, outlet pipe 16, steam vent 12.Flue 4 bottoms are provided with thermal insulation layer 2.The flue side is equipped with and is looked fire hole 17 and burner 18.Furnace shell 9 outsides are surrounded by rock wool 8, and with stainless steel sheet| 7 and last hoop 11, bind round 1 down and wrap.Said smoke pipe 6 is the threaded flue of screw-type, as shown in Figure 1 and Figure 2.Flue 4 changes low chamber flue into by the high pitched tune flue, and when flue wall of inner container diameter was 430MM, the height of flue was reduced to 330-360MM by 390MM.Smoke pipe 6 stretches out the height of lower perforated plate and reduces to 4-6MM by 10-15MM, promptly changes the low sidewall filled weld into by high sidewall filled weld, as shown in Figure 3, Figure 4.
