Machining device for multilayer composite heat preservation and corrosion preventing pipeline

Abstract

The invention discloses a machining device for a multilayer composite heat preservation and corrosion preventing pipeline. The machining device comprises a frame. A horizontal inner rod is arranged on the right side of the frame. The left end of the inner rod is fixedly connected with the frame. Multiple sets of fixing devices are arranged on the inner rod. Each fixing device comprise a sliding sleeve, multiple first connecting rods, multiple second connecting rods and multiple arc plates, wherein the sliding sleeve is arranged on the inner rod in a sleeving manner, the sliding sleeve can slide left and right along the inner rod, one ends of the multiple first connecting rods are connected with the outer side of the sliding sleeve in a hinged manner, the multiple first connecting rods are evenly distributed with the central axis of the sliding sleeve as the center, the other ends of the first connecting rods are connected with the inner side faces of the arc plates in a hinged manner, the second connecting rods are located on the left side of the sliding sleeve and are evenly distributed with the central axis of the inner rod as the center, one ends of the second connecting rods are connected with the inner rod in a hinged manner, and the other ends of the second connecting rods are connected with the side faces of the corresponding first connecting rods in a hinged manner. By means of the machining device, a ceramic outer layer which is even and has very good heat preservation and corrosion preventing effects can be rapidly formed on the periphery of a common pipeline at a time.

Description

technical field [0001] The invention belongs to the field of pipeline production tools, in particular to a multi-layer composite thermal insulation and anti-corrosion pipeline processing device. Background technique [0002] Ordinary metal pipelines have poor thermal insulation effect. The liquid in the pipeline is easy to freeze in cold winter or in severe cold areas, and it is very easy to be corroded and cannot be used for a long time when used in some areas with more corrosive components in the soil such as saline-alkali land. Ceramic is a material with very good thermal insulation effect and extreme corrosion resistance. Processing a layer of ceramic on the outer periphery of the metal pipeline will enable the pipeline to meet people's requirements for thermal insulation and corrosion resistance. However, the traditional processing technology is difficult to achieve in the pipeline. A complete ceramic layer is formed on the periphery at one time, so it is necessary to d...

[0002] Ordinary metal pipes have poor thermal insulation effect, and the liquid in the pipes is easy to freeze in cold winter or in severe cold areas, and it is very easy to be corroded when used in some saline-alkali lands and other areas where the soil contains a lot of corrosion components, so it cannot be used for a long time

Ceramic is a material with very good thermal insulation effect and extremely corrosion resistance. Processing a layer of ceramics on the outer periphery of metal pipes will enable the pipes to meet people's requirements for thermal insulation and corrosion resistance. However, traditional processing technology is difficult to achieve in the pipeline A complete ceramic layer is formed on the outer periphery at one time, so it is necessary to design a device that can quickly form a ceramic thermal insulation and anti-corrosion layer on the outer periphery of ordinary pipelines
