Abstract
The utility model relates to a sheath for a coal spraying pipe. The sheath comprises a framework sheathed on the outer side of the coal spraying pipe and palladium nails distributed on the end surface of the framework, and a fixing device for facilitating the fixation of the framework is arranged on the framework. The sheath disclosed by the utility model has the advantages of reducing the labor intensity, lowering the integrated cost and reducing the production cycle by sheathing the prefabricated framework on the outer side of the coal spraying pipe; and the saving way of the coal spraying pipe is simplified, the saving period is long, and the using effects are good.
Description
Technical field
The utility model relates to the coal injection pipe sheath.
Background technology
Coal injection pipe special-purpose fire-resistant material numerous in variety; but owing to use the position special; the tradition refractory material can not really play the effect of protection coal injection pipe; the outer on-the-spot system mill of traditional unsetting castable, Site, the cast-in-site of adopting of existing coal injection pipe; result of use is poor; the making integrated cost is high, long construction period, and service life is bad.
The utility model content
The existing coal injection pipe of the technical problems to be solved in the utility model is preserved bad with refractory material, result of use is poor, and comprehensive cost of manufacture is high, and the comprehensive manufacturing cycle is long, and service life is bad, thereby the coal injection pipe sheath is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the coal injection pipe sheath, and comprise the skeleton that is set in the coal injection pipe outside, be distributed in the palladium nail on the skeleton end face, described skeleton is provided with is convenient to the fixing fixture of skeleton.
Preferably, the cross section of described skeleton is annular, also can be other shapes of being convenient to process, and 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 is simple in structure, and result of use is good.
Preferably, described fixture also is the palladium nail, and simple in structure, result of use is good.
Preferably, described palladium nail also can be other shapes of being convenient to process for Y shape, and Y-shaped structure is simple, and result of use is good, is convenient to install.
Preferably, described palladium nail integral production also can be for other components be welded, and integral production is simple in structure, and result of use is good.
In sum, advantage of the present utility model: be set in the coal injection pipe outside by prefabricated skeleton, reduced labour intensity, reduced integrated cost, the production cycle descends, and the coal injection pipe preserving type is oversimplified, and retention cycle is long, and result of use is good.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model coal injection pipe sheath;
Fig. 2 is the cutaway view of A-A among Fig. 1.
The specific embodiment
Such as Fig. 1, shown in Figure 2, the coal injection pipe sheath comprises the skeleton 1 that is set in the coal injection pipe outside, be distributed in the palladium nail 2 on skeleton 1 end face, described skeleton 1 is provided with is convenient to the fixture 3 that skeleton 1 is fixed, the cross section of described skeleton 1 is annular, also can be other shapes of being convenient to process, cirque structure is simple, and 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 is simple in structure, and result of use is good, described fixture 3 also is the palladium nail, simple in structure, result of use is good, and described palladium nail 2 is Y shape, also can be other shapes of being convenient to process, Y-shaped structure is simple, and result of use is good, is convenient to install, described palladium is followed closely 2 integral productions, also can be for other components be welded, integral production is simple in structure, and result of use is good.
The surface is scribbled the heat-resisting steel part of pitch by being welded into the skeleton 1 that matches with coal injection pipe, be respectively equipped with palladium nail 2 in the outside of skeleton 1, skeleton 1 is set in the coal injection pipe outside, the palladium nail is fixed on skeleton 1 on the coal injection pipe on the skeleton 1 by being arranged on.
Be set in the coal injection pipe outside by prefabricated skeleton, reduced labour intensity, reduced integrated cost, the production cycle descends, and the coal injection pipe preserving type is oversimplified, and retention cycle is long, and result of use is good.
