Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a heat tracing structure for pipelines in refining and chemical plants. Background Technology

[0002] Existing pipe heat tracing structures include external heat tracing and fixed jacketed heat tracing. Among them, conventional external heat tracing is a widely used heat tracing technology. It has a simple structure and relatively low cost. However, the existing heat tracing pipe structure cannot adjust the distance between the heat tracing pipe and the pipeline as needed. If the distance between the heat tracing pipe and the pipeline is adjusted arbitrarily, it may not be possible to achieve the installation principle that multiple heat tracing pipes should be installed in parallel and that the relative positions of multiple heat tracing pipes should be fixed. Utility Model Content

[0003] This utility model proposes a pipeline heat tracing structure for refining and chemical equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pipeline heat tracing structure for a refining and chemical plant includes a main support. The main support has multiple mounting slots equidistantly arranged and multiple threaded mounting holes (I) equidistantly arranged. The threaded mounting holes (I) are located at the central axis of the mounting slots. A limiting block is slidably connected within each mounting slot. The limiting block is slidably connected to a heat-conducting metal block. Each limiting block includes a limiting shell. The top of the limiting shell has a threaded mounting hole (II). The limiting shell has two limiting holes (I) arranged in a centrally symmetrical manner with respect to the vertical centerline of the limiting shell. Sliding columns are respectively provided on the left and right end faces of the limiting shell. A pulley is rotatably connected to each sliding column. A heat tracing mounting hole 1 is provided through the limiting shell. The heat-conducting metal block includes a heat-conducting shell and a heat tracing mounting hole 2 is provided through the heat-conducting shell. The heat-conducting shell is provided with two limiting grooves, and the installation positions of the two limiting grooves are centrally symmetrical about the vertical center line of the heat-conducting shell. The heat-conducting shell is provided with two limiting holes 2, and the installation positions of the two limiting holes 3 are centrally symmetrical about the vertical center line of the heat-conducting shell. The center lines of limiting holes 2 and 3 coincide.

[0006] Furthermore, the overall outline of the mounting slot is rectangular.

[0007] Furthermore, the end face of the heat-conducting shell that contacts the pipe is designed to fit the pipe.

[0008] Furthermore, threaded mounting holes one and two are used to fix the main bracket and the limit block together with bolts.

[0009] Furthermore, thermal conductive adhesive can be applied between the thermally conductive shell and the pipe as needed.

[0010] Beneficial effects:

[0011] This invention controls the distance between the heat tracing pipe and the pipeline by adjusting the position of the limiting block on the heat-conducting metal block, thereby enabling the isolation pad between the heat tracing pipe and the pipeline to be set as needed. The limiting block and the main support are fixedly connected by bolts to ensure that multiple heat tracing pipes are installed in parallel and that their relative positions are fixed.

[0012] This utility model features a heat-conducting shell with a pipe-fitting design on one side, changing the traditional heat tracing method from heat radiation to heat conduction. Compared to external heat tracing, the arc-shaped contact method increases the heat transfer area. By adding heat-conducting putty as needed, the heat transfer coefficient of the heat tracing is expanded, greatly improving the heat exchange efficiency and reducing the heat consumption of the heat tracing pipe.

[0019] Reference Figure 1-3 A heat tracing structure for a refining and chemical plant pipeline includes a main support 1. The main support 1 has multiple mounting slots 2 equidistantly arranged, each mounting slot 2 having a rectangular overall outline. The main support 1 also has multiple threaded mounting holes 3 equidistantly arranged, each threaded mounting hole 3 located at the central axis of the mounting slot 2. A limiting block 4 is slidably connected within the mounting slot 2. The limiting block 4 is slidably connected to a heat-conducting metal block 11. The limiting block 4 includes a limiting housing 5. The top of the limiting housing 5 has a second threaded mounting hole 6. The threaded mounting holes 3 and 6 are fixed to the main support 1 and the limiting block 4 by bolts. The limiting housing 5 has two first limiting holes 7, whose installation positions are centrally symmetrically distributed around the vertical centerline of the limiting housing 5. The left and right end faces of the limiting housing 5 are respectively provided with sliding columns 8, each sliding column 8 having a pulley 9 rotatably connected to it, penetrating the limiting housing 5. The heat-conducting metal block 11 includes a heat-conducting shell 12, a heat-conducting mounting hole 13 penetrating the heat-conducting shell 12, two limiting grooves 14, the installation positions of the two limiting grooves 14 being centrally symmetrical about the vertical center line of the heat-conducting shell 12, two limiting holes 15, the installation positions of the two limiting holes 15 being centrally symmetrical about the vertical center line of the heat-conducting shell 12, and two limiting holes 17, the installation positions of the two limiting holes 17 being centrally symmetrical about the vertical center line of the heat-conducting shell 12. The center lines of the limiting holes 15 and 17 coincide. The end face of the heat-conducting shell 12 that contacts the pipe is designed to fit the pipe. Heat-conducting adhesive 16 can be installed between the heat-conducting shell 12 and the pipe as needed.

[0020] Working principle:

[0021] This utility model allows for selection of the contact distance between the heat tracing pipe and the pipeline according to actual conditions. During installation, firstly, the limiting block 4 is slidably connected to the mounting groove 2. Then, the bolt is manually used, with the bolt engaging with the threaded mounting hole 3. After the bolt passes through the main bracket 1, it engages with the threaded mounting hole 6 of the limiting block 4 to complete the fixing of the main bracket 1 and the limiting block 4. The heat tracing pipe 18 is then passed between the heat tracing mounting hole 10 and the heat tracing mounting hole 13. Then, the bolt is manually used to pass through the limiting hole 7, the limiting hole 15, and the limiting hole 17. The position of the limiting block 4 in the heat-conducting metal block 11 is adjusted as needed, and the limiting block 4 is fixed in the heat-conducting metal block 11 by bolts and nuts. This completes the fixing of the limiting block 4 in the heat-conducting metal block 11.

[0022] This invention allows for the control of the distance between the heat tracing pipe 18 and the pipeline by adjusting the position of the limiting block 4 on the heat-conducting metal block 11. This enables the on-demand setting of the isolation pad between the heat tracing pipe 18 and the pipeline. The limiting block 4 and the main support 1 are fixedly connected by bolts, ensuring parallel installation and fixed relative positions among multiple heat tracing pipes 18. The heat-conducting shell 12 of this invention features a pipeline-fitting design on one end face facing the pipeline, changing the traditional heat tracing heat exchange method from heat radiation to heat conduction. Compared to external heat tracing, the arc-shaped contact method increases the heat transfer area. By adding heat-conducting putty as needed, the heat transfer coefficient of the heat tracing is expanded, greatly improving the heat exchange efficiency and reducing the heat consumption of the heat tracing pipe 18.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
