Embodiment Construction

[0010] The present invention provides a material transportation pipe that is not easy to crystallize, including a main pipe 1, a layer of thermal insulation cotton 3 is coated on the outside of the main pipe 1, and several steam accompanying pipes 2 are embedded between the thermal insulation cotton 3 and the main pipe 1.

[0011] The main pipeline 1 is inclined at an angle of 15° to the conveying end in the horizontal direction.

[0012] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention, and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the present invention shall still belong to the scope covered by the patent of the present invention.

Abstract

The invention provides a non-crystalizing material conveying pipe. The non-crystalizing material conveying pipe comprises a main pipeline, and is characterized in that the outer side of the main pipeline is coated with a layer of heat-preserving cotton; a plurality of steam tracing pipes are embedded between the heat-preserving cotton and the main pipeline; the main pipeline tilts by 15 degrees towards one conveying end in a horizontal direction. The non-crystalizing material conveying pipe has the advantages and beneficial effects that hot steam is introduced into the steam tracing pipes, so that the temperature of the main pipeline can be kept, and conveyed materials are prevented from being crystallized; heat of the steam tracing pipes is utilized more effectively through the heat-preserving cotton on the outer sides of the steam tracing pipes, so that heat loss is reduced; by forming an inclination angle, materials in the main pipeline flow towards a source end when conveying is stopped, and are prevented from being left in the main pipeline and influencing next conveying.

Description

technical field [0001] The invention relates to a pipeline, in particular to a material transportation tube which is not easy to crystallize. Background technique [0002] Our company often needs to use pipelines to transport materials in production. Materials such as liquid sulfur will crystallize in colder climates, block pipelines, and cause production accidents. Therefore need a kind of pipeline that can solve this kind of problem. Contents of the invention [0003] The object of the present invention is to provide a material conveying pipe which is simple in structure and easy to realize and is not prone to crystallization. [0004] The technical solution of the present invention is: a material transport pipe that is not easy to crystallize, including a main pipe, characterized in that: the outer side of the main pipe is covered with a layer of thermal insulation cotton, and several steam accompanying pipes are embedded between the thermal insulation cotton and the m...
