Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a preheating and heat preservation device for chemical pipelines. Background Art

[0002] The main material of steel-plastic chemical pipe is ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with an average molecular weight greater than 2 million, which is polymerized by ethylene and butadiene monomers under the action of a catalyst. It has excellent comprehensive performance, and its wear resistance, low temperature resistance, corrosion resistance, self-lubrication, and impact resistance are the highest among all plastics. Its wear resistance is better than that of polytetrafluoroethylene, nylon, carbon steel and other materials. It can work for a long time under the conditions of -269 degrees to +80 degrees. It is called "amazing plastic" and is an ideal pipe.

[0003] Chemical pipelines are widely used in the process of transporting chemical materials. At the same time, the application scope and application scenarios of chemical pipelines are also very wide. For example, in some cold areas with low temperatures, when chemical materials are transported through chemical pipelines, the internal temperature of the pipeline is low. Some special chemical liquids are easily frozen in the chemical pipeline, which makes the chemical pipeline unable to transport chemical materials, affecting the actual use effect of the chemical pipeline. Therefore, the present application proposes a preheating and insulation device for chemical pipelines. Utility Model Content

At the same time, for low-temperature and severe cold areas, the outer wall of the chemical pipeline body can be electrically heated through an electric heating block. When the chemical pipeline is used to transport chemical materials, the chemical pipeline can be preheated in advance to improve the temperature of the chemical pipeline, thereby avoiding the freezing of chemical materials in the pipeline due to the low temperature of the chemical pipeline body. After preheating, the chemical pipeline body can be insulated through the insulation layer to ensure the transportation effect of the chemical pipeline on the chemical materials and improve the actual transportation efficiency of the chemical materials, so as to solve the problem that the chemical pipeline proposed in the above background technology is widely used in the process of chemical material transportation.

[0006] As a further solution of the utility model: the bottom ring and the top ring are both arranged in a semicircular ring structure, and the inner diameter size of the heating inner cavity matches the outer diameter size of the chemical pipeline body.

[0007] As a further solution of the utility model: the top and bottom portions of both sides of the bottom ring and the top ring close to each other are fixedly connected with connecting plates, and the tops of the two connecting plates are threadedly connected with a plurality of connecting bolts.

[0008] As a further solution of the utility model: the bottom of the bottom ring is fixedly connected to a support base, the bottom outer walls on both sides of the support base are fixedly connected to connecting blocks, and the tops of the two connecting blocks are threadedly connected with fixing bolts.

[0009] As a further solution of the utility model: the outer walls of the chemical pipeline body on both sides of the top ring and the bottom ring are fixedly connected with support rings.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: in the utility model, the chemical pipeline body is insulated by the insulation layer. At the same time, for low-temperature and severe cold areas, the outer wall of the chemical pipeline body can be electrically heated by the electric heating block. When the chemical pipeline is transporting chemical materials, the chemical pipeline can be preheated in advance to increase the temperature of the chemical pipeline, thereby avoiding the freezing of chemical materials in the pipeline due to the low temperature of the chemical pipeline body. After preheating, the chemical pipeline body can be insulated by the insulation layer to ensure the transportation effect of the chemical pipeline on chemical materials and improve the actual transportation efficiency of chemical materials.
