The utility model has the advantages of the reasonable structure, the small size, and the high thermal efficiency of the heat absorption wing in the hearth; the boiler body, the hearth and the combustion chamber are all cast elements; the maintenance, disassembly and replacement are convenient; the service life is long.
Description
Technical field
The utility model belongs to civilian small atmospheric boiler, particularly the design and the manufacturing technology field of inboard wall of burner hearth band heat absorption wing lamination comb serpentine waterways combined small normal-pressure boiler.
Background technology
At present, commercially available small-sized civilian normal-pressure boiler kind is more.Based structures is welded type.Wherein most of unreasonable except that structure, cause that coal consumption is higher, the thermal efficiency low, and all be welded with steel.Thereby perishable, life-span weak point, because local corrosion causes whole boiler to scrap.A kind of " lamination comb serpentine waterways small atmospheric boiler " arranged is patented product.Its patent No. is ZL200420031436.9.The advantage of this product is, and is rational in infrastructure, volume is little, quick heating, province's coal, thermal efficiency height.Dismantled and assembled, make long service life by cast iron.Its weak point is, do not have in the burner hearth heat absorption wing and heat absorption fire grate and with the combustion chamber be an integral body, comparatively heavy, great difficulty is also arranged during casting.In addition, it does not have dedusting to scrape hawk, can not strike off pot dust of body water pipe outside.
Summary of the invention
The purpose of this utility model is that a kind of inboard wall of burner hearth band heat absorption wing lamination comb serpentine waterways combined small normal-pressure boiler is provided.
This reality is novel to be achieved by the following scheme:
The utility model is made up of pot and stove two parts.Pot body, interior outer casing, front and rear cover and chimney interface that pot is scraped hawk by band are connected and fixed with bolt to be formed.It is the sandwich-type shell, and inside is the lamination comb, serpentine waterways.Stove is combined by burner hearth and combustion chamber.
Each as a whole ironcasting of burner hearth and combustion chamber.Inboard wall of burner hearth has vertical heat absorption wing.Burner hearth has fire door, upper and lower water course and connected entrance thereof, water inlet, delivery port, and fire door is in the bottom, dead ahead.Upper and lower water course in the burner hearth is communicated with by linker.There is interior screw thread the burner hearth top and the bottom for four jiaos.
There are ash hole and fire bars in the combustion chamber, and four jiaos have bolt hole.
Pot, burner hearth and combustion chamber are connected and fixed successively by bolt and become boiler.
Scrape hawk and be welded into an integral body by seven sheets, it and comb mate, and certain interval is arranged between the two, so that ash is scraped in pulling.Scraping the hawk both sides has four points and outside to scrape the hawk pull bar to link to each other.Scraping the hawk pull bar is stretched out by the hawk pull bar mouth of scraping of outer casing.
The utility model has the advantages that rational in infrastructure, volume is little, the heat absorption wing is arranged in the burner hearth, quick heating, thermal efficiency height, pot body and front and rear cover, burner hearth and combustion chamber are formed by ironcasting, and dismounting, maintenance, replacing are conveniently economized on coal long service life.

The specific embodiment
The utility model is made up of pot and stove.
The pot body has screw thread 12 in pot body, connects gripper shoe 13 and water channel 11, and a pot body is equipped with to be scraped hawk 20, be connected in the hawk pull bar of scraping on the hawk 20 21 of scraping and stretched out by the hawk pull bar mouth 7 of scraping on the outer casing 8.
Its rear end has covered pot water inlet 17 and delivery port 18.Drive end bearing bracket 5 and rear end cap are fixed in pot body on the screw thread 12 by bolt of cover 4, and inner casing 19 and outer casing 8 are by being bolted to the external side of pot.Chimney interface 6 is arranged at pot body top.
Pot body drive end bearing bracket 5, rear end cap are foundry goods.Wherein the pot body can be weldment, but it is perishable, and service life is short.
