Abstract
The utility model discloses a convenient-to-connect composite material conveying pipe comprising a wear-resistant ceramic pipe and a metal pipe. The composite material conveying pipe comprises the silicon carbide ceramic pipe (1) with the length in a range of 0.8-1.2m and the inner diameter in a range of 180-300mm, wherein the silicon carbide ceramic pipe (1) is sleeved with the steel pipe (2), and the length of the steel pipe (2) is the same as that of the silicon carbide ceramic pipe (1); flange plates (3) are arranged at two ends of the steel pipe (2); and a filling layer (4) is arranged between the steel pipe (2) and the silicon carbide ceramic pipe (1). With the adoption of the convenient-to-connect composite material conveying pipe, the inner diameter of the silicon carbide ceramic pipe is set within the range of 180-300mm, the silicon carbide ceramic pipe is applicable to conveying of pulverized coal and the like, and the ceramic pipe is wear-resistant, so that the problem of wear resistance of existing conveying pipes for the pulverized coal and the like is solved. The silicon carbide ceramic pipe is sleeved with the steel pipe, and the flange plates are connected to the two ends of the steel pipe, so that the problem of butt joints of the ceramic pipe is solved, and the butt joints are convenient. In addition, the steel pipe can be used for supporting the weight of the ceramic pipe, so that the breaking phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of conveyance conduit, particularly a kind of composite material conveying tube be combined into by wear resistance ceramic tube and metal tube connected of being convenient to.
Background technique
At present, the pipeline for delivery of coal dust as uses such as thermal power plants mostly adopts steel pipe or wear-resistant steel pipe as conveyance conduit, facts have proved, under the transport condition that is 45 meter per seconds at the pulverized fuel ash flow velocity, the impact resistance of seamless steel pipe is poor, and the shock point of the seamless steel pipe elbow that wall thickness is 10mm just there will be hole to start to leak in 40 days.
In order to solve wear-resisting problem, at present, also have factory to adopt earthenware duct as conveyance conduit, but, because ceramic own wt is large, when the internal diameter of earthenware duct is larger, the length of stoneware pipe itself just is difficult to do length, otherwise transport, install, will be all pretty troublesome.Therefore, can only adopt a section stoneware pipe docking to dress up a conveyance conduit.But bad processing during the stoneware pipe joint, secondly because the weight of stoneware pipe itself is large, be prone to the phenomenon of fracture after docking.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of composite material conveying tube be combined into by wear resistance ceramic tube and metal tube connected of being convenient to.
To achieve these goals, the technical solution of the utility model is as follows: a kind of composite material conveying tube be combined into by wear resistance ceramic tube and metal tube connected of being convenient to, it is characterized in that: comprise silicon carbide ceramic (1), the length of described silicon carbide ceramic (1) is 0.8-1.2m, the internal diameter of described silicon carbide ceramic (1) is 180-300mm, described silicon carbide ceramic (1) overcoat has steel pipe (2), the length of described steel pipe (2) is identical with the length of silicon carbide ceramic (1), the two ends of described steel pipe (2) are provided with flange plate (3), between described steel pipe (2) and silicon carbide ceramic (1), be packed layer (4).
Adopt technique scheme, at the internal diameter of silicon carbide ceramic, make 180-300mm, the internal diameter size is suitable as the conveyance conduit of coal dust etc., length 0.8-1.2m, and weight is moderate, and convenient transportation is installed.Stoneware pipe is wear-resisting, has solved the wear-resisting problem of the delivery pipes such as current coal dust.At the silicon carbide ceramic outer steel pipe, the two ends mounting flange of steel pipe, solved the docking problem of stoneware pipe, and docking is convenient.And steel pipe can, for supporting the weight of stoneware pipe, be avoided the phenomenon of fracture.
In technique scheme: in order to improve wear resistance, convenient docking, solve the easily broken problem of docking, and the pipe thickness of described silicon carbide ceramic (1) is 10-15mm, the thickness of described packed layer (4) is 5-15mm, and the pipe thickness of described steel pipe is 5-10mm.
As preferably: described steel pipe (2) is the Q235 steel pipe.
As preferably: described packed layer (4) is comprised of cement and silicon carbide.
As preferably: described packed layer (4) is made by thermoinsulation material.
Beneficial effect: the utility model is simple in structure, low cost of manufacture, and wear resistance is good, and docking is convenient.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
When for delivery of pipeline, the wear resistance ceramic tube that more piece is such is formed by connecting by flange plate 3.
