Description
Technical field
The present invention relates to a kind of seal arrangement, specifically is a kind of slide block type sealing structure that is used for slit between sealed boiler furnace roof and the spring hanger link.
Background technique
At present, the spring hanger link of boiler furnace roof mainly stretches into outside furnace roof and is used to suspend in midair the Boiler Steam superheater in the furnace roof, expanding with heat and contract with cold of Boiler Steam superheater can cause waving of spring hanger link, the vibrations that produce with the steam flush superheater simultaneously, therefore, pass between the suspension rod of furnace roof and furnace roof and can produce the slit, this slit need seal, to reduce thermal loss, improve efficiency of boiler and avoid thermo-pollution.
In the prior art, the sealing in this slit normally seals with the filling of soft thermal insulating material or around being banded in suspension rod, so that furnace roof position flue gas is blocked on around the suspension rod in the burner hearth, but there are some following defectives in this sealing means:
1, the gap sealing of suspension rod and furnace roof, though just enabling and during cold conditions, sealability is better, but after hot or use a period of time, because of the expanding with heat and contract with cold and shake of Boiler Steam superheater, make gap sealing filler between suspension rod and the furnace roof take place loosening and sealing is destroyed, thereby make the slit place generation smoke spillage of boiler furnace roof place flue gas at suspension rod and furnace roof, increase the boiler smoke thermal loss, reduced the hot benefit of boiler operatiopn.
2, the high-temperature flue gas that has at boiler furnace roof place that causes because of above-mentioned reason leaks, and boiler furnace roof outside wall temperature is raise, and influences boiler working life, and need seal maintaining repeatedly to the boiler furnace roof, has increased the regular maintenance expense.
3, the smoke spillage that causes because of above-mentioned reason, owing to more or less can contain CO (carbon monoxide converter) gas in the flue gas, aggravating working environment, and to regular maintenance formation potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, easy construction, long service life and the slide block type sealing structure that is used for slit between sealed boiler furnace roof and the spring hanger link free from environmental pollution.
The object of the invention realizes by following technological scheme: described slide block type sealing structure comprises circular sealed sliding block assembly and passes the spring hanger link in its axle center; Spring hanger link passes the sealed sliding block assembly; It is characterized in that: described sealed sliding block assembly comprises the circular housing body and the fixed block, movable block and the pressing plate that are assemblied in this frame of upper end open; Described fixed block is a ring, and close installation is fixed in the frame, and the internal diameter of fixed block inwall reduces from top to down gradually, forms the inverted cone chamber; The shape of described movable block is corresponding with this inverted cone chamber, and be assemblied in the inverted cone chamber, movable block is made of the semicircle cone of two symmetries, offer the internal diameter closed hole identical on the movable block shaft axis with the spring hanger link diameter, spring hanger link passes the sealing hole, and sealing hole inwall contacts with the spring hanger link intimate; Described pressing plate is assemblied in the frame, is pressed on described fixed block and the movable block.
As a further improvement on the present invention, described frame, fixed block and pressing plate are made up of the symmetrical semicircular shell of two geometrical shapies, semi-round ring shape fixed block and the butt joint of semicircle pressing plates respectively, so that site operation installation and to the regular maintenance of boiler body.
As a further improvement on the present invention, evenly be laid with 4 vertical guide rod holes on described fixed block and the pressing plate, 4 location guides pass through described guide rod hole, the location guide lower end is fixed on the frame bottom, pressing plate is assemblied in the frame, the pressing plate butt joint of two semicircle pressing plates is vertical mutually with the housing butt joint of two semi-round ring shape housings, in the guide rod hole on the location guide upper end insertion pressing plate; When spring hanger link all around moved, whole sealed sliding block assembly utilized the mutual self-locking of location guide, remains an integral body.As a further improvement on the present invention, described fixed block and movable block adopt composite aluminium oxide material to be made.
Described sealed sliding block assembly supports also and between the dunnage and can relatively move by the dunnage in the boiler furnace roof wall; The bottom of described frame closely contacts with described dunnage; Described spring hanger link passes dunnage simultaneously, and the outer top of boiler furnace roof steelframe is fixed in the upper end of spring hanger link, the lower end suspention steam superheater of spring hanger link.
The present invention is simple and reasonable, and easy construction is compared with prior art safe and reliable, good sealing effect, and long service life, the boiler hot remarkable benefit improves, and production environment is not produced thermo-pollution; Satisfying under the service condition, the sealed sliding block assembly is reusable during the boiler maintenance.
