Abstract
The invention provides a small-opening header for being matched with a boiler. The header comprises a header body and flanges. The header body is a thin-wall metal hollow cylinder. Opening contracting and opening expanding are sequentially conducted on the two symmetrical ends of the header body. The left end and the right end of the header body are provided with the flanges respectively in a welded mode. The small-opening header is characterized in that the header further comprises protection fixing blocks, supporting plates, welding plates, supporting frames and positioning plates. A plurality of protection fixing blocks are fixed to the surface of the header body in a welding mode. The supporting plates are arranged on the protection fixing blocks respectively. The supporting plates and the protection fixing blocks form inclined angles. The welding plates are connected to the protection fixing blocks in a welding mode. Four supporting frames are arranged on the left end and the right end, symmetrical to the welding faces of the protection fixing blocks, of the surface of the header body, wherein every two of the four supporting frames are symmetrical to each other. The positioning plates are connected to the supporting frames. The small-opening header is simple in structure and easy to implement, the welding damage to the header is reduced, the quality of the header is improved, and the service life of the header is prolonged.
Description
Technical field
The present invention relates to boiler header field, is a kind of cooperation boiler osculum header in particular.
Background technology
Header is exactly a container in fact.The furnace wall of station boiler is stitched together by several rows of pipe to form.But be pipe be entirely not all right, boiler volume is huge, complex structure, can not in all pipes medium---the caloric receptivity of water is all much the same, and in fact some places are also far short of what is expected, and certain position fills header, the water inside each pipe is allowed to converge here, go in next stage each pipe of reallocation, can thermal deviation be reduced like this, make the heat absorption of working medium, flowing, the cooling of boiler, boiler thermal output are all optimized raising; Be exactly that the specification size of boiler upper, middle and lower part each section of pipe, pipe radical and arrangement are all different in addition, header is just responsible for connecting each section, ensures that the circulation of working medium is smooth and easy.Such as, but existing commercially produced header or some defect, inconvenient seamless link boiler, header bore hour, is inconvenient to gather, and when bore is large, easily the situations such as leakage occurs again.
Summary of the invention
In order to solve the problem, the invention provides and see a kind of cooperation boiler osculum header.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of cooperation boiler osculum header, described header comprises casing, flange, described casing is thin-wall metal hollow cylinder, the enlarging again and first close up symmetrically in two ends, on a left side for described casing, the equal welded flange of right-hand member, it is characterized in that described header also includes protection fixed block, gripper shoe, welded plate, bracing frame, location-plate, some protection fixed blocks are fixed with in the surface soldered of described casing, each protection fixed block is welded with gripper shoe, arrange in oblique angle between described gripper shoe and the solid block of protection, welded plate is welded with on described protection block is fixing, with a left side for the tank surface of described protection fixed block solder side symmetry, 4 bracing frames symmetrical are between two welded at right two ends, support frame as described above connected positioning plate.
Described welded plate 5 can be determined according to the mounting structure of described header and boiler.
The invention has the beneficial effects as follows:
1. header structure described in is simple, easily realizes;
2. reduce the welding damage of header, improve header quality, extend the service life of header.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is left view of the present invention;
Wherein: 1-casing, 2-flange, the solid block of 3-protection, 4-gripper shoe, 5-welded plate, 6-bracing frame, 7-location-plate.
Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As depicted in figs. 1 and 2, the present invention is a kind of cooperation boiler osculum header, described header comprises casing 1, flange 2, described casing 1 is thin-wall metal hollow cylinder, the enlarging again and first close up symmetrically in two ends, on a left side for described casing 1, the equal welded flange 2 of right-hand member, it is characterized in that described header also includes protection fixed block 3, gripper shoe 4, welded plate 5, bracing frame 6, location-plate 7, some protection fixed blocks 3 are fixed with in the surface soldered of described casing 1, each protection fixed block 3 is welded with gripper shoe 4, arrange in oblique angle between described gripper shoe 4 and the solid block 3 of protection, described protection block is fixed on 3 and is welded with welded plate 5, with the left side on casing 1 surface of described protection fixed block 3 solder side symmetry, 4 bracing frames 6 symmetrical are between two welded at right two ends, support frame as described above 6 connected positioning plate 7, can according to the needs of erecting and welding structure, determine the concrete shape of welded plate 5, described location-plate 7 is positioned over ground when this header does not use, support described header.
The principle of described header is: adopt protection fixed block 3 transition header to replace header directly to weld with boiler with the direct welded structure mode in boiler space, reduce the welding damage of header, improve header quality, extend the service life of header.
The invention has the beneficial effects as follows:
1. header structure described in is simple, easily realizes;
2. reduce the welding damage of header, improve header quality, extend the service life of header.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and change; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
