Description

Oil-fired water-boiler furnace structure

Technical field

The utility model relates to a kind of boiler furnace structure, especially a kind of oil-fired water-boiler furnace structure.

Background technique

Existing oil-fired water-boiler includes that cross section is that circular shell is stopped, and has insulating layer on the outside of shell, shell Top is connected to smoke evacuation tracheae, and the lower part of shell is fixedly connected with bottom plate, and bottom plate is fixedly supported on pedestal by pillar, in bottom plate Burner using fuel oil as fuel is installed between pedestal, the combustion head being connected with burner body is located at the upper surface of bottom plate； There is the water storage component to connect with water inlet tap and faucet in shell, water storage component is cricoid water jacket, i.e. the middle part of shell is Double-layer structure forms water jacket between two layers.When burner operation, enclosure interior is heated by combustion head, the water quilt in water jacket Heating.The heating surface area of oil-fired hot-water boiler's furnace interior water storage part part of this structure is small, and water is excessively concentrated in water jacket, wastes energy Source, boiler work the rising of initial stage water temperature slowly；Heat caused by combustion head can rise in shell rapidly and from smoke discharging Pipe discharge, causes boiler thermal efficiency low.

Summary of the invention

The purpose of the utility model is to provide a kind of structures simply, increases boiler shell inner storing water component heating surface area, mentions High thermal efficiency, the oil-fired water-boiler furnace structure for saving the energy, overcome the deficiencies in the prior art.

The oil-fired water-boiler furnace structure of the utility model, including cross section are circular shell, in the outside of shell There is insulating layer, the top of shell is connected to smoke evacuation tracheae, and the lower part of shell is fixedly connected with bottom plate, and bottom plate is supported by the way that pillar is fixed On pedestal, burner is equipped between bottom plate and base plate, the combustion head being connected with burner body is located at the upper surface of bottom plate；? There is the water storage component to connect with for water nozzle and faucet in shell.

The water storage modular construction are as follows: have two layers of standpipe the inner peripheral of shell is evenly distributed, wherein one layer for by The outer layer standpipe of nearly case inside wall, another layer are the internal layer standpipe on the inside of outer layer standpipe, outer layer standpipe and internal layer standpipe It is distributed for concentric circumferences, and interlaced setting；It is fixed with upper annular water chamber on housing cavity top, under the inner cavity of shell Portion is fixed with lower annular water chamber, upper annular water chamber, lower annular water chamber respectively with the upper end of outer layer standpipe and internal layer standpipe, lower end phase It connects, and the lower inner cavity of the upper inner cavity of upper annular water chamber and lower annular water chamber is connected with the inner cavity of outer layer standpipe and internal layer standpipe It is logical.

There is through-hole in the centre of upper annular water chamber, form heating room positioned at the lower section of upper annular water chamber in shell, Smoke-box is formed in the top of upper annular water chamber, smoke-box is connected to smoke evacuation tracheae.

The combustion head is located at the center of lower annular water chamber.

The oil-fired water-boiler furnace structure of the utility model, it is each vertical due to there is two layers of evenly distributed standpipe in shell Pipe top and bottom are communicated with annular water chamber and lower annular water chamber, concentrate water excessively in shell, branch in each pipe and In upper annular water chamber, lower annular water chamber, hence it is evident that increase heating surface area, improve the thermal efficiency, save the energy, boiler starts to transport Water temperature rises fast when row, and the upper annular water chamber on housing cavity top plays a barrier effect to heat rising, and flue gas can be from upper Through-hole at annular water chamber center is discharged upwards, has prevented most of heat and has had little time the drawbacks of heat exchange is expelled directly out.Have Structure is simple, increases boiler shell inner storing water component heating surface area, improves the thermal efficiency, saves the advantages of energy.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；

Fig. 2 is A-A section enlarged diagram shown in FIG. 1.

Specific embodiment

As shown in Figure 1, 2: the oil-fired water-boiler furnace structure of the utility model, including cross section are circular shell 4, There is insulating layer 5 in the outside of shell 4, the top of shell 4 is connected to smoke evacuation tracheae 1, and the lower part of shell 4 is fixedly connected with bottom plate 9, bottom Plate 9 is fixedly supported on pedestal 12 by pillar 10.Fuel oil type burner 11 is installed between bottom plate 9 and pedestal 12, with combustion The connected combustion head 13 of 11 ontology of burner is located at the upper surface of bottom plate 9, and the connecting portion of combustion head 13 and 11 ontology of burner is just Central hole on bottom plate 9.There is the water storage component to connect with for water nozzle and faucet in shell 4.

Water storage modular construction are as follows: have two layers of standpipe the inner peripheral of shell 4 is evenly distributed, wherein one layer is close to shell The outer layer standpipe 6 of 4 inner sidewalls, another layer are the internal layer standpipe 7 positioned at 6 inside of outer layer standpipe, outer layer standpipe 6 and internal layer standpipe 7 It is distributed for concentric circumferences, and interlaced setting (referring to Fig. 2).It is fixed with upper annular water chamber 3 on 4 inner cavity top of shell, The inner cavity lower part of shell 4 is fixed with lower annular water chamber 8, upper annular water chamber 3, lower annular water chamber 8 respectively with outer layer standpipe 6 and internal layer Upper end, the lower end of standpipe 7 connect, and the lower inner cavity 15 of the upper inner cavity 16 of upper annular water chamber 3 and lower annular water chamber 8 and outer layer are vertical Pipe 6 is connected with the inner cavity of internal layer standpipe 7.
