Abstract
A sealing device of a boiler economizer ventilation beam relates to a sealing device used in the boiler economizer ventilation beam, which solves the problem that the existing sealing device of the boiler economizer ventilation beam is big in welding difficulty, poor in quality after being welded, apt to occur tear of partial welding line, and not tight in sealing of steel plate to cause heat loss. An inner steel plate is fixedly connected with one end of the ventilation beam, a coaxial through holes are arranged in the middles of the inner steel plate, a supporting steel plate and an outer steel plate, one end of a steel tube penetrates through the through hole of the supporting steel plate and stretches to the through hole of the inner steel plate, the steel tube is fixedly connected with the inner steel plate, the supporting steel plate is fixedly connected with the steel tube, the other end of the steel tube stretches out of the middle through hole of the outer steel plate which is fixedly connected with the steel tube, a sealing steel tube is sleeved on the steel tube and placed between the supporting steel plate and the outer steel plate, the sealing steel tube and the steel tube are coaxially arranged, an annular protrusion is arranged on the lateral wall of the sealing steel tube, two ends of the sealing steel tube are respectively and fixedly connected with the supporting steel plate and the outer steel plate to form an expanding joint sealing device, and sealing thermal insulation materials are laid between the expanding joint sealing device and the steel tube. The sealing device is used for sealing of the boiler economizer ventilation beam.
Description
Technical field
The utility model relates to a kind of sealing device of boiler economizer ventilation beam.
Background technology
The sealing of boiler economizer ventilation beam at present is to adopt by steel plate to make crooked expansion joint, an end and channel-section steel welding, and a quadra is formed in the other end and the welding of ventilation beam end.Its corner sealing plate size is less, is difficult to welding, and postwelding is second-rate, when boiler operatiopn, occurs local weld seam easily and tears, and steel plate is poorly sealed, produces to leak the cigarette phenomenon, causes heat loss.
The utility model content
The purpose of the utility model provides a kind of sealing device of boiler economizer ventilation beam; Big to solve existing boiler economizer ventilation beam sealing device welding difficulty; Postwelding is of poor quality; When boiler operatiopn, occur local weld seam easily and tear, steel plate is poorly sealed, produces the problem of leaking the cigarette phenomenon and causing heat loss.
The utility model is made up of steel pipe 1, interior steel plate 2, supporting steel plate 3, outer steel plate 4, sealed steel pipe 5 and sealing insulation material 6, and it is characterized in that: interior steel plate 2 is fixedly connected with an end of ventilation beam 7, the middle part of the middle part of interior steel plate 2, supporting steel plate 3 reach outer steel plate 4 the middle part all have coaxial through hole; One end of steel pipe 1 passes the through hole of supporting steel plate 3 and stretches in the through hole of steel plate 2 in the people; Steel pipe 1 is fixedly connected with interior steel plate 2, and supporting steel plate 3 is fixedly connected with steel pipe 1, and the other end of steel pipe 1 passes the middle part through hole of outer steel plate 4; Outer steel plate 4 is fixedly connected with steel pipe 1; Sealed steel pipe 5 is sleeved on the steel pipe 1, and sealed steel pipe 5 places between supporting steel plate 3 and the outer steel plate 4, sealed steel pipe 5 and steel pipe 1 coaxial setting; The sidewall of sealed steel pipe 5 is provided with annular protrusion; The two ends of sealed steel pipe 5 respectively with supporting steel plate 3 and the outer steel plate 4 expansion joint sealing device that is composed of a fixed connection, lay between expansion joint sealing device and the steel pipe 1 and seal insulation material 6, supporting steel plate 3 is fixedly connected with channel-section steel 8.Steel pipe 1 is fixedly connected with ventilation beam 7 through interior steel plate 2 and stretches out outside the backplate.
The utlity model has following beneficial effect:
The sealing surface of said sealing device is circular, seal easyly, effective, and solder side is circular weld bond, is prone to welding, and the postwelding good forming effect is difficult for the generation weld defect.Expansion joint is arranged in the high-temperature area, absorbs swell increment through it, avoids producing the local cracking in weld bond place owing to stress is concentrated and causes leaking the cigarette phenomenon, has guaranteed sealing in Boiler Furnace performance and safe and stable operation.Said sealing device can be widely used in the sealing of boiler economizer ventilation beam.
