Abstract

The utility model discloses a small water heating boiler, which consists of a gallbladder and a sleeve, etc. A plurality of fireproof plates with profile of U-shape are indented welded in the gallbladder; when the heat flows in the gallbladder, the stroke of the smoke is prolonged, in order to cause the heat sufficiently and fast absorbed; the water in the boiler can be heated to requirement temperature in extremely short time. The utility model has simple structure, high heat efficiency (the heat efficiency can reach 70-80 percent according to the test), saves the fuel, reduces the heating cost, and has longer service life compared with the traditional boiler.

Description

Small-sized hot water space heating boiler

Technical field: the utility model relates to boiler, relates in particular to be fit to the medium and small hot water space heating boiler that family uses.

Background technology: how can improve the thermal efficiency of boiler under the prerequisite of fuel saving, be the dominant ideas of boiler design.As everyone knows, the fuel in the boiler is in combustion heating, and the temperature of the flue gas that produces is also quite high.At present, most boiler is owing to its structural reason on the market, and the flow process of the flue gas that fuel combustion produced in stove is very short, therefore can not collect utilization well for this part heat, so just caused heat to run off in vain, not only wasted fuel, the thermal efficiency is also very low.Secondly, existing boiler is short service life, and this also allows the consumer not satisfied.

It is fast that the purpose of this utility model provides a kind of heating, thermal efficiency height, fuel savings, and the small-sized hot water space heating boiler of long service life.

Technical scheme: the purpose of this utility model is achieved in that

The utility model mainly partly is made up of inner bag and overcoat two, and inner bag and overcoat form the water jacket of the strap clamp layer of a sealing through welding; The bottom of inner bag is the combustion chamber, has the fire door that mends the fire on the sidewall of combustion chamber; The top of inner bag is smoke flow channels, in order to allow flue gas in inner bag, stop the long period, it is the distance that prolong smoke flows in passage, in this section inner bag, the some sections of indenting welding are the battle plate of " U " type, three of battle plate not blind end all be opened on the water jacket that inner bag and overcoat form, leave certain distance between blind end and the wall of inner container; Above the fire door that mends the fire, have ash discharge fire door and temperature control fire door successively, the blind end of these two fire doors two battle plates in the inner bag; In the bottom of battle plate, many row's arc dust boards are arranged, when upwards flow in the space of flue gas between battle plate, the dust in the flue gas can be kept off layer by layer by dust board; In order to make full use of heat, also can add one deck boiler in addition at top of the present utility model, boiler is around around the outlet flue, and the heat that utilizes outlet flue and boiler top to be distributed comes the water in the heating water tank.

Described in detail below in conjunction with accompanying drawing.

Fig. 1 is a front elevation of the present utility model;

Fig. 2 is the sectional side view of Fig. 1;

Fig. 3 is the cutaway view of another embodiment of the utility model;

Fig. 4 is the cutaway view of the another embodiment of the utility model

Fig. 5 is the structure diagram of dust board;

Fig. 6 be among Fig. 3 A-A to cutaway view;

As shown in the figure:

Inner bag 7 and overcoat 1 form the water jacket of the strap clamp layer of a sealing after welding; The bottom of inner bag 7 is combustion chamber 10, has the fire door 5 that mends the fire on the sidewall of combustion chamber 10; The top of inner bag 7 is smoke flow channels, in this section inner bag, the some sections of indenting welding be the battle plate 6 of " U " type, three of battle plate 6 not blind end communicate with the water jacket of inner bag 7 and overcoat 1 formation, leave certain distance between the wall of the blind end of battle plate 6 and inner bag 7; Above the fire door 5 that mends the fire, have ash discharge fire door 4 and temperature control fire door 3, these two fire doors are over against the blind end of inner bag 7 interior two battle plates 6; The taking environmental conservation into consideration factor in the bottom of battle plate 6, has many row's arc dust boards 8, and when upwards flow in the space of flue gas between battle plate 6, the dust in the flue gas can be kept off layer by layer by dust board 8, clears up away from ash discharge fire door 4 and temperature control fire door 3 then.

During use, fuel is fully burning in combustion chamber 10, and heat promptly flows along arrow direction among the figure, because the surface area of battle plate 6 is big than traditional water pipe surface area, so its speed that absorbs heat is also faster, corresponding transmission heat is fast, boiler hot also fast.

If want to control temperature in the stove, only need to regulate the folding degree of temperature control fire door 3, can achieve the goal.

In order to make full use of heat, also can add one deck boiler 11 in addition at top of the present utility model, boiler 11 be looped around outlet flue 2 around, utilize heat that outlet flue 2 and boiler top the distributed water in can heating water tank 11, can be for the usefulness of generally washing one's face and rinsing one's mouth.

Except that said structure, the utility model has provided another embodiment as shown in Figure 3, in this embodiment, battle plate 6 is arranged relatively, leaves the space between two battle plates 6, both sides up and down at upper strata battle plate 6, with battle plate 6 vertical direction, be provided with two and hang courage 12, its effect is to change the flow of flue gas direction, make fire walk boiler operation principle and above-mentioned being as good as to both sides.

The utility model has also proposed another embodiment as shown in Figure 4, in this embodiment, considers if the height of boiler increases, owing to can not unrestrictedly increase air door quantity, can increase some water pipes 9 in the inner bag above the battle plate 67, water pipe 9 communicates with the boiler chuck.

Beneficial effect: adopt above-mentioned measure, when flue gas flowed in inner bag, flue gas flow was prolonged, make heat can be fully, promptly absorbed by boiler body, in a short period of time, the water in the boiler can be heated to temperature required, thereby the also corresponding fuel of having saved, reduced the heating cost.The utility model is simple in structure, and thermal efficiency height (according to surveying and determination, the thermal efficiency can reach 70--80%) in addition, adopts this structure of battle plate, has also prolonged the service life of boiler greatly.

Claims (2)

1, a kind of small-sized hot water space heating boiler, form by inner bag and overcoat etc., it is characterized in that: the some sections of indenting welding are the battle plate of " U " type in the inner bag, three of battle plate not blind end be opened on water jacket between inner bag and the overcoat, leave certain distance between blind end and the wall of inner container; Above the fire door that mends the fire, have ash discharge fire door and temperature control fire door successively, and the blind end of two fire doors, two battle plates in the inner bag.
