Abstract
The utility model 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 wear 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 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 utility model relates to a kind of sintering machine suction channel compensation device that expands with heat and contract with cold, and relates in particular to a kind of super 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 because the huge negative pressure of sintering machine main induced draft fan can produce a large amount of solid particles to bellows, corrugated expansion joint, bellows, wait other pipelines to wash away, wear and tear.So corrugated expansion joint is when connecting bellows and large flue, when guaranteeing certain extending amount, internal duct must stand solid particle to its strong wear.
The compensator of using in the engineering at present, simple in structure, cheap, although section'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 bellows of its tube wall weakness, and very fast compensator reaches its working life.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of corrugated expansion joint of Effective Raise abrasion-resistance, and this compensator has advantages of that the life-span is long, simple in structure.
For achieving the above object the following technological means of employing of the present utility model:
A kind of super wear-resisting type corrugated expansion joint, comprise the Wear resistance disk that is positioned at the compensator front end, the rear portion of Wear resistance disk is provided with diameter greater than the front wear-resisting end pipe of Wear resistance disk internal diameter, the outer back end gap of front wear-resisting end pipe is arranged with rear wear-resisting end pipe, and described bellows two ends are separately fixed on front wear-resisting end pipe and the rear wear-resisting end pipe.
Further, the Spielpassung place of the wear-resisting end pipe of described front wear-resisting end Guan Yuhou is provided with Stamping Steel Ribbon.
Further, described front wear-resisting end pipe comprises the front tube fixing with Wear resistance disk, and the front tube rear is fixed with honeycomb duct, and rear wear-resisting end pipe box is located at outside the honeycomb duct.
Further, be provided with wear ring in the described honeycomb duct.
Further, be fixed with ring flat-plate on front wear-resisting end pipe, the rear wear-resisting end pipe, the bellows two ends are separately fixed on the ring flat-plate.
Further, the Wear resistance disk internal diameter is 3/4ths of wear-resistant pipe.
Further, described wear ring is three roads.
The beneficial effects of the utility model show:
The utility model is set up Wear resistance disk at the front end of compensator, and the internal diameter of Wear resistance disk is less than being positioned at the thereafter diameter of pipeline, 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 resistance disk is playing protection compensator inwall, also play the effect that connects the sintering machine wind box flange, be convenient to installation, the debugging of whole 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 utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1, a kind of super wear-resistant corrugated pipe compensator, the ring flat-plate 3 that comprises corrugated stainless steel tubing 4 and be fixed on its two ends, ring flat-plate 3 is 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 fixed with Wear resistance disk 1 usefulness bolt.
For preventing that solid particle from entering the flexible chamber of bellows, and play the axial displacement compensating action, wear-resisting honeycomb duct 5 cooperates with end pipe 7 gaps, and is sealed by Stamping Steel Ribbon 6.
For increasing the inner abrasive resistance of corrugated expansion joint, honeycomb duct 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 resistance disk 1 material adopts 16Mn, and thickness and wear-resisting honeycomb duct 5 are consistent, and its diameter of bore is 2/3 or 3/4 of wear-resisting honeycomb duct 5 inner diameters.When solid particle when the compensator, this transition contraction structure has strengthened the washing away of Wear resistance disk 1, and has reduced the wearing and tearing to wear-resisting honeycomb duct 5.
During use, this corrugated expansion joint and sintering machine wind box, flue are connected to the bellows flange and Wear resistance disk 1 usefulness bolt links together, and flange plate 8 is bolted together with the flue flange of sintering machine equipment.
