Description

Technical Field

[0001] This utility model relates to the field of heat tracing pipeline technology, specifically an explosion-proof connection structure for heat tracing pipelines. Background Technology

[0002] Heat tracing pipes, also known as heat tracing pipes, are used to trace the heat source of flue gas, pressure guide pipes, regulating valves, process pipelines, or instruments and insulation boxes directly installed on process equipment. Heat tracing pipes prevent the viscosity of the liquid inside the pipe from increasing at low temperatures, thus preventing increased pressure drop and power consumption, thereby saving energy. Due to the length and angle of the heat tracing pipes, connecting structures are required to connect them.

[0003] However, the current heat tracing pipelines have poor sealing performance, which makes it easy for gas and liquid to leak at the connection points. In severe cases, this can lead to explosions and pose certain safety hazards. Therefore, those skilled in the art have provided an explosion-proof connection structure for heat tracing pipelines to solve the problems mentioned in the background art. Utility Model Content

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-5In this embodiment of the utility model, an explosion-proof connection structure for a heat tracing pipeline includes two heat tracing pipes 1 and two connecting plates 9. Each heat tracing pipe 1 includes an anti-corrosion layer 101, a wear-resistant layer 102, a waterproof layer 103, an explosion-proof layer 104, a protective layer 105, a heat tracing cable 106, and a flexible hose 107. A first baffle 2 is fixedly connected to the outer surface of one heat tracing pipe 1, and a second baffle 4 is fixedly connected to the outer surface of the other heat tracing pipe 1. Two connecting blocks 11 are fixedly connected to the outer surfaces of both connecting plates 9. Each set of connecting blocks 11 has a circular hole 12 on one side that is close to each other. Ear plates 10 are fixedly connected to the left and right sides of the two connecting plates 9. A positioning ring 7 is fixedly connected to the right side of the first baffle 2, and a sealing ring 18 is fixedly connected to the right side of the positioning ring 7. A positioning groove 8 is opened on the left side of the second baffle 4. This not only makes it convenient for people to connect the heat tracing pipeline, but also makes the connection of the heat tracing pipeline more stable. This solves the problem mentioned in the background technology that the current heat tracing pipeline has poor sealing effect, which makes the connection of the heat tracing pipeline prone to leakage of gas and liquid, and in severe cases, it can cause an explosion, posing certain safety hazards.

[0025] The outer surface of the flexible hose 107 is connected to the heat tracing cable 106, the outer surface of the heat tracing cable 106 is connected to the protective layer 105, the outer surface of the protective layer 105 is connected to the explosion-proof layer 104, the outer surface of the explosion-proof layer 104 is connected to the waterproof layer 103, the outer surface of the waterproof layer 103 is connected to the wear-resistant layer 102, and the outer surface of the wear-resistant layer 102 is connected to the anti-corrosion layer 101. Each set of round holes 12 is fitted with a positioning pin 13, and the outer surfaces of the two positioning pins 13 are threaded with nuts 14. This allows the heat tracing pipe 1 to have the characteristics of being waterproof, corrosion-resistant, wear-resistant, and explosion-proof, thereby greatly increasing the service life of the equipment.

[0026] Rubber layers 3 are fixedly connected to the sides of the two connecting plates 9 that are close to each other. A sealing gasket 15 is fitted on the outside of each positioning pin 13. A ring-shaped positioning rod 5 is fixedly connected to the right side of the first baffle 2. A positioning hole 6 is opened at equal intervals on the left side of the second baffle 4. A groove 16 is opened on the bottom surface of the two ear plates 10. A positioning post 17 is fixedly connected to the upper surface of the two ear plates 10. This not only greatly increases the stability of the heat tracing pipeline connection, but also makes the sealing effect of the equipment better.

[0027] The working principle of this utility model is as follows: First, the positioning ring 7 and the positioning rod 5 can be inserted into the positioning groove 8 and the positioning hole 6 respectively. Then, the connecting plate 9 and the ear plate 10 can be inserted into the outside of the first baffle 2 and the second baffle 4. Next, the positioning pin 13 can be inserted into the round hole 12. Then, the nut 14 can be tightened until the positioning pin 17 is completely inserted into the groove 16. The sealing ring 18, the sealing gasket 15 and the rubber layer 3 can prevent leakage at the connection of the heat tracing pipeline.
