Description
Technical Field
The utility model particularly relates to a carborundum pipeline.
Background
The conveying of materials is involved in pulverized coal conveying in the thermal power industry, coke dry quenching dust removal pipelines in the steel industry, and elevators, selection systems and dust removal systems in the cement industry, and the conveying pipeline is material conveying equipment widely applied in the industries. However, the conveying pipelines adopted at present are generally cylindrical pipeline structures, materials are easy to deposit at the elbow and the bottom of the pipeline during conveying, the pipeline is blocked, and the dredging and maintaining process is very complicated. In addition, the material often can cause very big wearing and tearing to the pipeline wall surface, and some powder still can produce the corruption to the pipeline, need constantly overhaul the maintenance, not only cause very big environmental pollution, still reduced the operating efficiency of enterprise and increased the operating cost of enterprise and operator's intensity of labour.
Disclosure of Invention
In view of this, the utility model provides a carborundum pipeline to the problem that prior art exists. The technical scheme of the utility model is that:
a silicon carbide conveying pipeline comprises an outer layer steel pipe and an inner layer ceramic rubber pipe, wherein the ceramic rubber pipe is composed of rubber and a silicon carbide ceramic block compounded in the rubber, and one surface of the silicon carbide ceramic block exposed in the rubber is a wear-resistant working surface; a filling layer is arranged between the steel pipe and the ceramic rubber pipe; at least one row of ash blowing holes are formed in the steel pipe in a penetrating mode through the ceramic rubber pipe, the aperture of each ash blowing hole is 3-5 mm, and the hole distance between every two adjacent ash blowing holes is 1 m; and flanges are arranged at two ends of the steel pipe.
Further, the silicon carbide ceramic blocks on the ceramic rubber tube are arranged in the rubber in a staggered mode.
Furthermore, a rubber cover is arranged at an outlet of the soot blowing hole, and the soot blowing hole is perpendicular to the wall of the pipeline.
Further, the filling layer is made of a heat insulating material.
The technical effects of the utility model are that: the utility model discloses simple structure, reasonable in design, the butt joint is convenient, can increase substantially pipeline's abrasion resistance and erosion resistance, not only can reduce the maintenance frequency, practices thrift manufacturing cost, alleviates intensity of labour, can prolong the life of pipeline moreover, improves productivity.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings and specific examples, which are given by way of illustration and not of limitation.
As shown in fig. 1 and 2, the utility model provides a structural schematic diagram of a silicon carbide conveying pipeline, which comprises an outer steel pipe 1 and an inner ceramic rubber pipe 2, wherein the ceramic rubber pipe 2 is composed of rubber 3 and silicon carbide ceramic blocks 4 compounded in the rubber 3, the silicon carbide ceramic blocks 4 are arranged in the rubber 3 in a staggered manner, and the exposed surface of the silicon carbide ceramic blocks 4 in the rubber 3 is a wear-resistant working surface; and a filling layer 5 is arranged between the steel pipe 1 and the ceramic rubber pipe 2, and the filling layer 5 is made of a heat insulating material.
At least one row of ash blowing holes 6 are formed in the steel pipe 1 through the ceramic rubber pipe 2, the aperture of each ash blowing hole 6 is 3-5 mm, and the hole distance between every two adjacent ash blowing holes 6 is 1 m; the outlet of the soot blowing hole 6 is provided with a rubber cover 8, the rubber cover 8 is used for sealing the soot blowing hole and pulling the soot blowing hole down when the pipeline is maintained and cleaned so as to facilitate the ash removal of the pipeline. The soot blowing holes 6 are arranged perpendicular to the pipe wall. The both ends of steel pipe 1 are equipped with ring flange 7, and the effect of ring flange has two, makes things convenient for the pipeline to erect or take off, and on the other hand allows multisection pipeline to establish ties and uses in order to make things convenient for longer distance's transport.
To summer up, the utility model discloses simple structure, reasonable in design, the butt joint is convenient, can increase substantially pipeline's abrasion resistance and erosion resistance, not only can reduce the maintenance frequency, practices thrift manufacturing cost, alleviates intensity of labour, can prolong the life of pipeline moreover, improves productivity.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
