Abstract
The invention provides a super-wear-resisting corrugated expansion joint, which is characterized in that the inner diameter of a wear-resisting disk is 3/4 that of the inner wall of a diversion pipe, and the wear-resisting disk is used for weakening the washing and abrading effects of solid particles on the diversion pipe; the diversion pipe is made of a metal thickening material and additionally provided with a wear-resisting ring on the inner wall, so that the wear resistance in the expansion joint is improved; and the diversion pipe is in clearance fit with an end pipe, and the diversion pipe and the end pipe are sealed by virtue of a sealing strip. With adoption of the designed structure, the service life of the expansion joint is three times that of the ordinary expansion joint.
Description
Technical field
The present invention relates to a kind of sintering machine air draught road rising-heat contracting-cold compensating device, relate in particular to a kind of ultra wear-resisting type corrugated expansion joint.
Background technique
The bellows of existing steel enterprise sintering machine and large flue are at work because certain relative displacement variation can appear in temperature variation; And, wait other pipelines to wash away, wear and tear because the huge negative pressure of sintering machine main exhauster can produce a large amount of solid particles to bellows, corrugated expansion joint, bellows.So corrugated expansion joint is when connecting bellows and large flue, when guaranteeing certain extending amount, internal duct must stand the strong wear of solid particle to it.
The compensator of using in the engineering at present; Simple in structure, cheap, though portion's honeycomb duct has carried out wear-resisting design within it; But still can not satisfy on-the-spot needs; After the honeycomb duct wearing and tearing, a large amount of solid particles carries out impact wear to the weak bellows of its tube wall, and very fast compensator reaches its working life.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of corrugated expansion joint of effective raising abrasion-resistance, and this compensator has long, advantage of simple structure of life-span.
For achieving the above object the following technological means of employing of the present invention:
A kind of ultra wear-resisting type corrugated expansion joint; Comprise the wear-resisting dish that is positioned at the compensator front end; The rear portion of wear-resisting dish be provided with diameter greater than wear-resisting dish internal diameter before wear-resisting end pipe; Before the outer back end gap of wear-resisting end pipe be arranged with the wear-resisting end pipe in back, before said bellows two ends are separately fixed on wear-resisting pipe and the wear-resisting end pipe in back.
Further, the Spielpassung place of the wear-resisting end pipe of wear-resisting end Guan Yuhou is provided with Stamping Steel Ribbon before described.
Further, the front tube that wear-resisting end pipe comprises and wear-resisting dish is fixing before said, the front tube rear is fixed with honeycomb duct, and the wear-resisting end pipe box in back is located at outside the honeycomb duct.
Further, be provided with wear ring in the said honeycomb duct.
Further, be fixed with ring flat-plate on preceding wear-resisting end pipe, the wear-resisting end pipe in back, the bellows two ends are separately fixed on the ring flat-plate.
Further, wear-resisting dish internal diameter is 3/4ths of a wear-resisting pipe.
Further, said wear ring is three roads.
Beneficial effect of the present invention shows:
The present invention sets up wear-resisting dish at the front end of compensator, and the internal diameter of wear-resisting dish is less than being positioned at the diameter of pipeline thereafter, and this kind contraction structure can weaken solid particle to the washing away, wear and tear of honeycomb duct, and prolongs its working life.
In addition, when wear-resisting dish is playing protection compensator inwall, also play the effect that connects the sintering machine wind box flange, be convenient to installation, the debugging of entire equipment.
The wear-resisting end pipe in front and back adopts Spielpassung and adopts Stamping Steel Ribbon to seal; This project organization; When the fatigue fracture of stainless steel expansion pipe, adopt this project organization, when assurance is not leaked out; Compensator can also prolong its working life more than 1 year, was 3 times of working lifes of common corrugated expansion joint.
Below in conjunction with embodiment the present invention is further specified.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The following correlation technique content of not addressing all can adopt or use for reference existing technology.
As shown in Figure 1; A kind of ultra wear-resisting type corrugated expansion joint, the ring flat-plate 3 that comprises corrugated stainless steel tubing 4 and be fixed on its two ends, ring flat-plate 3 are welded on respectively on the two side ends pipe 10,7; The end pipe 10,7 of both sides is welded on respectively on the flange plate 2 of both sides; The rear end of end pipe 10 is provided with honeycomb duct 5, and honeycomb duct 5 outsides are arranged with end pipe 7, and flange plate 2 is used bolt with wear-resisting dish 1.
For preventing that solid particle from getting into the flexible chamber of bellows, and play the axial displacement compensating action, Spielpassung between wear-resisting guide shell 5 and the end pipe 7, and seal by Stamping Steel Ribbon 6.
For increasing the inner abrasive resistance of corrugated expansion joint, guide shell 5 materials adopt 16Mn, and thickness is the twice of end pipe 7,10, and wall welds three road wear rings 9 within it.
For further improving the inner abrasive resistance of its compensator, wear-resisting dish 1 material adopts 16Mn, and thickness and wear-resisting guide shell 5 are consistent, and its diameter of bore is 2/3 or 3/4 of wear-resisting guide shell 5 inner diameters.When solid particle when the compensator, this transition contraction structure has strengthened the washing away of wear-resisting dish 1, and has reduced the wearing and tearing to wear-resisting guide shell 5.
During use, this corrugated expansion joint and sintering machine wind box, flue are connected to the bellows flange and wear-resisting dish 1 usefulness bolt links together, and flange plate 8 is bolted together with the flue flange of sintering machine equipment.
