Description

The normal-pressure hot-water boiler body

The utility model relates to a kind of parts with normal-pressure hot-water boiler of heat-generating device.

China Patent No. 91229889.8 utility model patent specifications disclose a kind of gerotor type fuel oil hot water boiler, the combustion chamber is located at the body of heater bottom, between body of heater and the combustion chamber by water spacer, the fire tube that is communicated with the combustion chamber is communicated with smoke-box by water tank, and feed pipe is by smoke-box, and the water in the feed pipe enters earlier the body of heater water tank again after the smoke-box preheating, above-mentioned water heater is a kind of improvement to traditional water heater, though the thermal efficiency improves, the current disorder, the thermal efficiency is not ideal enough.

The purpose of this utility model is to propose a kind of current and hot gas antikinesis and is the body of the normal-pressure hot-water boiler of many backhauls.

Technical solution adopted in the utility model is that this boiler body has 2～4 jacket type drums, its chuck chamber is water cavity, inlet opening and flame export are arranged on an end of drum, the other end that apopore and flame import are arranged on, be connected by water pipe between top drum apopore in the adjacent drum and the drum inlet opening, below, be connected by the fire tube that is arranged in the water pipe between top drum flame import in the adjacent drum and the below drum flame export, between adjacent drum link be set.

Place the drum of the top to be provided with drain in the above-mentioned boiler body, place that the drum of below is provided with sewage draining exit, be equipped with the hand verify on the drum.

Link between drum is " " shape elastic support.

Can in drum chuck chamber, be provided with spirality eddy flow plate around the drum inner bag.

Can in the drum chamber, be provided with the water pipe that 1～3 two ends is communicated with drum chuck chamber.

Can in the drum chamber, be provided with the water pipe that 3 above two ends are communicated with drum chuck chamber.

Can in only being provided with 1～3 water pipe chamber in the water pipe drum, be provided with and be fixed on spirality eddy flow plate on its inwall.

The utility model has changed the structure of conventional hot water boiler, adopt many drums formula, cold water enters the chuck chamber and the water pipe chamber of this drum from the inlet opening of the top drum, through several backhauls, flow out by apopore after entering the drum chuck chamber of below at last, heat exchange area is bigger, and hot gas from the combustion chamber that is placed at below drum inner chamber toward rising, by fire tube is that exhaust opening is discharged by the flame export of the top drum at last, water and hot gas antikinesis, heat can fully be absorbed, and the flow direction of the utility model water is orderly, to chuck, pipe inner wall plays certain souring, make inwall less scaling, also play a role to improving the thermal efficiency, in the chuck chamber with in the water pipe chamber, spirality eddy flow plate is set, not only increased heat exchange area, and because the water rotational flow, make souring more obvious, model machine after tested, the thermal efficiency is higher than 92%; The utility model utilizes the drum inner chamber as flue, because of the carbon distribution phenomenon of blocking can reduce.The vertical phase stack structure of horizontal drum has made full use of the space, and boiler finished product floor space is not because of increasing of drum increases, and is opposite because single drum volume is little, and the boiler floor space is reduced.

Fig. 1 is structure (analysing and observe) diagrammatic sketch of embodiment 1;

Fig. 2 is structure (analysing and observe) diagrammatic sketch of embodiment 2.

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment 1 shown in Figure 1 adopts three drums in upper, middle and lower, drum is jacket type, has inner bag 4, the inner bag shape is similar to hull shape, and chuck chamber 3 is water cavity, and inner chamber is fiery chamber, for increasing the current backhaul, take inlet opening 10 and flame export 9 to be arranged on an end of drum, apopore 14 and flame import 18 are arranged on the other end, and the one or both ends end socket of drum is provided with hand verify 11.The inlet opening 10-1 of upper drum is arranged on drum cylindrical tube top, its flame export is that exhaust opening 9-1 is arranged on side or the top with the upper drum cylindrical tube of end, apopore 14-1 and flame import 18-1 are in the same position of upper drum, be arranged on upper drum cylindrical tube other end bottom, evacuation port 2 is arranged on the upper drum top; In flame export 9-2 and the inlet opening 10-2 of drum be arranged on the top of the corresponding end of drum cylindrical tube and upper drum apopore 14-1, its flame import 18-2 and apopore 14-2 are arranged on the bottom of the middle drum cylindrical tube other end; The inlet opening 10-3 of the drum of below and the top that flame export 9-3 is arranged on a drum cylindrical tube end corresponding with middle drum apopore 14-2, its apopore 14-3 is arranged on lower drum cylindrical tube other end bottom, the flame import of lower drum is that burner installing hole 18-3 is arranged on the drum end socket of this drum apopore 14-3 with end, and sewage draining exit 15 is arranged on the lower drum bottom.Be upper drum apopore 14-1 between the drum inlet opening of drum apopore and the below of top in the adjacent drum with middle drum inlet opening 10-2 between reach between middle drum apopore 14-2 and lower drum inlet opening 10-3 and be connected by water pipe 17-1,17-2 respectively, into and out of center, water hole one to; Apopore 14-1, the inlet opening 10-2 of drum are in same position respectively with separately for upper drum flame import 18-1 in the adjacent drum, middle drum flame export 9-2, be connected by the fire tube 16-1 that is arranged in the water pipe 17-1 between upper drum flame import 18-1 and the middle drum flame export 9-2, equally, in be connected by the fire tube 16-2 that is arranged in the water pipe 17-2 between drum flame import 18-2 and the lower drum flame export 9-3, the chuck chamber of water pipe 17 and 16 formation of fire tube is an aquaporin.Removing, the drum of below is the combustion chamber because of its inner chamber, the water pipe 6 that two ends are communicated with the chuck chamber all is set in other the drum chamber, in all drum chuck chambeies, be provided with spirality eddy flow plate 7 around drum inner bag 4, the eddy flow plate is fixed on the inner bag, similar to external screw thread, eddy flow plate length is generally the length of inlet opening to apopore, spirality eddy flow plate 8 is set in water pipe 6 chambeies equally, the eddy flow plate is fixed on the pipe inner wall, similar to internal thread, be provided with passive link 13 between drum, consider heat expansion cause the distortion of each drum differ to, should flexibly connect between drum, connect and put up " " shape, form, slightly tool elasticity by steel plate bending, for reducing the pressure of this part drum housing, link is fixed on the drum housing by liner plate 12.
