Abstract
The invention relates to a coal injection pipe sheath. The coal injection pipe sheath comprises a framework and palladium nails, wherein the framework is sleeved on the outer side of a coal injection pipe, the palladium nails are distributed on the end face of the framework, and a fixing device for facilitating the fixation of the framework is arranged on the framework. The coal injection pipe sheath has the advantages that the prefabricated framework is sleeved on the outer side of the coal injection pipe, so that the labor intensity and the comprehensive cost are reduced, the production cycle is shortened, the storage mode of the coal injection pipe is simplified, the storage cycle of the coal injection pipe is long, and the using effect is good.
Description
Technical field
The present invention relates to coal injection pipe sheath.
Background technology
Coal injection pipe special-purpose fire-resistant material numerous in variety; but owing to using position special; tradition refractory material really can not play the effect of protection coal injection pipe; existing coal injection pipe skin adopts traditional unsetting castable scene system mill, Site, cast-in-site; result of use is poor; making integrated cost is high, long construction period, and service life is bad.
Summary of the invention
The technical problem to be solved in the present invention existing coal injection pipe refractory material is preserved bad, and result of use is poor, and comprehensive cost of manufacture is high, and the comprehensive manufacturing cycle is long, and service life is bad, thus provides coal injection pipe sheath.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: coal injection pipe sheath, comprises and be set in the skeleton outside coal injection pipe, the palladium nail be distributed on skeleton end face, and described skeleton is provided with is convenient to the fixing fixture of skeleton.
Preferably, the cross section of described skeleton is annular, and the shape also can being convenient to processing for other, cirque structure is simple, and result of use is good.
Preferably, described skeleton is welded by heat-resisting steel part, also can be other building blocks, and heat-resisting steel part structure is simple, and result of use is good.
Preferably, described fixture is also palladium nail, and structure is simple, and result of use is good.
Preferably, described palladium nail is Y shape, and the shape also can being convenient to processing for other, Y-shaped structure is simple, and result of use is good, is convenient to install.
Preferably, described palladium nail integral production, also can be welded for other components, integral production structure is simple, and result of use is good.
In sum, advantage of the present invention: be set in outside coal injection pipe by prefabricated skeleton, decrease labour intensity, reduce integrated cost, the production cycle declines, and coal injection pipe preserving type is simplified, and retention cycle is long, and result of use is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of coal injection pipe sheath of the present invention;
Fig. 2 is the sectional view of A-A in Fig. 1.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, coal injection pipe sheath, comprise the skeleton 1 be set in outside coal injection pipe, be distributed in the palladium nail 2 on skeleton 1 end face, described skeleton 1 is provided with is convenient to the fixing fixture 3 of skeleton 1, the cross section of described skeleton 1 is annular, also can for other be convenient to process shape, cirque structure is simple, result of use is good, described skeleton 1 is welded by heat-resisting steel part, also can be other building blocks, heat-resisting steel part structure is simple, result of use is good, described fixture 3 is also palladium nail, structure is simple, result of use is good, described palladium nail 2 is Y shape, also can for other be convenient to process shape, Y-shaped structure is simple, result of use is good, be convenient to install, described palladium follows closely 2 integral productions, also can be welded for other components, integral production structure is simple, result of use is good.
Heat-resisting steel part surface being scribbled pitch, by being welded into the skeleton 1 matched with coal injection pipe, being respectively equipped with palladium nail 2, being set in outside coal injection pipe by skeleton 1 in the outside of skeleton 1, be fixed on coal injection pipe by skeleton 1 by being arranged on palladium nail on skeleton 1.
Be set in outside coal injection pipe by prefabricated skeleton, decrease labour intensity, reduce integrated cost, the production cycle declines, and coal injection pipe preserving type is simplified, and retention cycle is long, and result of use is good.
