Abstract
The utility model provides an anti-abrasion and vibration-preventing device of a first row of tube bundles in a head smoke flow direction of a heating surface on the tail part of a boiler. The anti-abrasion and vibration-preventing device comprises two rods transversely spanned on the boiler tube bundle in a horizontal direction, and are fixed by using a cross rod. The anti-abrasion and vibration-preventing device is characterized in that angle irons are fixed outside an erosion surfaces of the boiler tube bundles, two sides of the cross rod are respectively fixedly provided with one angle iron, an anti-abrasion cover is spanned between the two angle irons, the rods are arranged below the anti-abrasion cover, one end of the anti-abrasion cover is welded and fixed with the angle irons, and the other end of the anti-abrasion cover is not fixed. The angle irons are used for replacing the original arc-shaped steel, thus the process difficulty is greatly lowered; and meanwhile, the anti-abrasion is additionally provided, and after thermal expansion, gaps are directly prevented from being impacted by a high-speed soot blowing medium due to the anti-abrasion cover. Furthermore, one end of the anti-abrasion cover is fixed, and the other end of the anti-abrasion cover is not fixed, the influence to expansion to the anti-abrasion cover can be eliminated.
Description
Technical field
The utility model relates to a kind of heated surface at the end of boiler and meets the first comb bundle of flue gas flow direction abrasionproof vibration proof device.
Background technology
As shown in Figure 1, for existing boiler tube bundle vibrationproof shoe sketch map, in this structure, in order to prevent the vibration of pipe in the boiler tube bundle 13, shockproof bar 11 is in the horizontal direction across being welded on the boiler tube bundle 13.Shockproof bar 11 by two prolongations and form with the bar 15 that the stove bar fuses, two bars 15 are fixing by a cross bar 17, to support boiler tube bundle 13, prevent that boiler tube from vibrating when operation.Simultaneously, receive to blow washing away of grey medium at a high speed and wear and tear for fear of boiler tube bundle 13, receiving welding arc protective plate 21 on the wash surface, owing to the influence of bar 15, arc protective plate 21 can only be welded on the both sides of bar 15 respectively.The shortcoming of said structure is: 1, owing to need the arc protective plate 21 fine boiler tube bundles 13 of must fitting, so boiler maker man need come oneself to bend arc protective plate 21 according to the size of boiler tube bundle 13, wastes time and energy; 2, behind expanded by heating, just can form gap 23 between arc protective plate 21 and the shockproof bar 11, this gap 23 can directly receive at a high speed blows washing away of grey medium and weares and teares.
Summary of the invention
The purpose of the utility model provides a kind of device that reduces manufacture difficulty and better prevent the boiler tube bundle wearing and tearing.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of heated surface at the end of boiler and has met the first comb bundle of flue gas flow direction abrasionproof vibration proof device, comprises that horizontal direction across two bars on boiler tube bundle, fixed by a cross bar between two bars; It is characterized in that: boiler tube bundle receive be fixed with angle steel outside the wash surface; The fixing respectively angle steel in the both sides of bar, across an abrasionproof cover, bar is positioned at abrasionproof cover below between two blocks of angle steel; Welding is fixed between one end of abrasionproof cover and the angle steel, and the other end is fixing.
Further, be respectively equipped with a shrouding, to seal the space between this abrasionproof cover and the said angle steel in the both sides of said abrasionproof cover.
The utility model has adopted angle steel to replace original arc steel, greatly reduces technology difficulty, simultaneously, has increased the abrasionproof cover, behind expanded by heating, because the existence of abrasionproof cover prevents that the gap directly receives the impact of blowing grey medium at a high speed.Further, an end of abrasionproof cover is fixed, and the other end is unfixing, can get rid of the influence of expansion for the abrasionproof cover.

The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 2, meet the first comb bundle of flue gas flow direction abrasionproof vibration proof device for a kind of heated surface at the end of boiler that the utility model provides, comprise that horizontal direction is across two bars 15 on boiler tube bundle 13; Fixing between two bars 15 by a cross bar 17, boiler tube bundle 13 receive be fixed with angle steel 1 outside the wash surface, a fixing respectively angle steel 1 in the both sides of bar 15; Between two blocks of angle steel 1 across an abrasionproof cover 2; Bar 15 is positioned at abrasionproof cover 2 belows, and welding is fixed between an end of abrasionproof cover 2 and the angle steel 1, and the other end is fixing; Be respectively equipped with a shrouding in the both sides of abrasionproof cover 2, to seal the space between this abrasionproof cover 2 and the angle steel 1.
The utility model adopts angle steel 1 to replace the arc steel, and bending of angle steel 1 is comparatively convenient, and can increase abrasionproof cover 2 simultaneously to cover the gap between formed bar 15 of tube expansion and the angle steel 1 from outer buying.And an end of abrasionproof cover 2 is fixed, and the other end is unfixing, is in order to adapt to the expansion of pipe, and is last, seals up shrouding in both sides, stops flue gas to get into from the gap.
