When used, the building structure is abrasion-resistant, is high in strength, is conveniently repaired in an emergency condition, and is economical and practical; the prefabricated bricks and the refractory castings are distributed on two side surfaces of the steel plate of the lower opening of the hot air returning pipe in a staggered manner; the widths of the prefabricated bricks are the same with those of the refractory castings; at least one prefabricated brick is arranged between the refractory castings; and the prefabricated bricks are high in fire resistance, cannot drop, are simple in structure and convenient to build and can completely replace the refractory castings, and the service life of the lower opening of the hot air returning pipe is prolonged.
Description
Technical field
The utility model relates to a kind of masonry construction, is specifically related to a kind of backheat wind pipeline infraoral masonry construction.
Technical background
At present backheat wind pipeline infraoral adopts welding anchor studs, adopts plank formwork to synchronize with central cooler furnace roof to pour into a mould the masonry construction of castable refractory.Backheat wind pipeline infraoral need to bear high temperature gas flow, the erosion of breeze and washing away, the coefficient of expansion and the central cooler furnace roof of backheat wind pipeline infraoral steel structure, the castable refractory coefficient of expansion of the synchronous cast of backheat wind pipeline infraoral differs larger, the stress that backheat wind pipeline infraoral steel structure and castable refractory produce, there is castable refractory crackle, hot blast blows the anchor studs that is welded on the solid castable refractory of target on steel structure, cause castable refractory bulk to come off, cause backheat wind pipeline infraoral steel structure scaling loss, again change steel structure and pour into a mould refractory casting material process loaded down with trivial details, work high above the ground difficulty is large, service life is short, have a strong impact on benefit economy.
Therefore, production is a kind of simple in structure, easy to operate, and long service life, constructs simple and easy, and equipment operation ratio is high, and a kind of backheat wind pipeline infraoral masonry construction of firm and durable, has market prospects widely.
Summary of the invention
The purpose of this utility model be to overcome deficiency of the prior art and a kind of simple in structure, easy to operate, long service life is provided, construction is simple and easy, equipment operation ratio is high, the backheat wind pipeline infraoral masonry construction of firm and durable.
The technical solution of the utility model is achieved in that a kind of backheat wind pipeline end opening brick masonry structure, comprise backheat wind pipeline infraoral steel plate, inner side and the outside of described backheat wind pipeline infraoral steel plate are all welded with anchor studs, anchor studs outside is filled with block castable refractory, between castable refractory, be provided with preformed bricks, in preformed bricks, be provided with built-in fitting, preformed bricks is welded on the inside and outside both sides of backheat wind pipeline infraoral steel plate by built-in fitting, be provided with fire resistant seal bar between preformed bricks and castable refractory.
Described preformed bricks and castable refractory all present staggered distribution in the two sides of backheat wind pipeline infraoral steel plate, and the width of preformed bricks and castable refractory equates.
The preformed bricks arranging between described castable refractory is at least one.
The utlity model has following good effect: first, this product structure is simple, comprise backheat wind pipeline infraoral steel plate, inner side and the outside of described backheat wind pipeline infraoral steel plate are all welded with anchor studs, anchor studs outside is filled with block castable refractory, between castable refractory, be provided with preformed bricks, in preformed bricks, be provided with built-in fitting, preformed bricks is welded on the inside and outside both sides of backheat wind pipeline infraoral steel plate by built-in fitting, between preformed bricks and castable refractory, be provided with fire resistant seal bar, in use, this product resistance to erosion, intensity is large, emergency service is convenient, be that economy is practical again, secondly, preformed bricks and castable refractory all present staggered distribution in the two sides of backheat wind pipeline infraoral steel plate, the width of preformed bricks and castable refractory equates, the preformed bricks arranging between castable refractory is at least one, and the fire-resistant intensity of preformed bricks is large, does not come off, simple in structure, it is convenient to build by laying bricks or stones, can replace castable refractory structure completely, improves backheat wind pipeline infraoral service life.
Accompanying drawing explanation
Fig. 1 is the utility model internal structure schematic diagram.
Fig. 2 is the utility model side structure schematic diagram.
The specific embodiment
As shown in Figure 1, 2, a kind of backheat wind pipeline infraoral masonry construction, comprise backheat wind pipeline infraoral steel plate 1, inner side and the outside of described backheat wind pipeline infraoral steel plate 1 are all welded with anchor studs 2, anchor studs 2 outsides are filled with block castable refractory 4, between castable refractory 4, be provided with preformed bricks 3, in preformed bricks 3, be provided with built-in fitting 5, preformed bricks 3 is welded on the inside and outside both sides of backheat wind pipeline infraoral steel plate 1 by built-in fitting 5, between preformed bricks 3 and castable refractory 4, be provided with fire resistant seal bar 6.
Described preformed bricks 3 and castable refractory 4 all present staggered distribution in the two sides of backheat wind pipeline infraoral steel plate 1, and the width of preformed bricks 3 and castable refractory 4 equates.The preformed bricks 3 arranging between described castable refractory 4 is at least one.
In use, resistance to erosion, intensity is large, emergency service is convenient for the utility model, and economy is practical again.Preformed bricks and castable refractory all present staggered distribution in the two sides of backheat wind pipeline infraoral steel plate, the width of preformed bricks and castable refractory equates, the preformed bricks arranging between castable refractory is at least one, the fire-resistant intensity of preformed bricks is large, do not come off, simple in structure, it is convenient to build by laying bricks or stones, can replace castable refractory structure completely, improve backheat wind pipeline infraoral service life.
