Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline antifreeze technology, and in particular to an electric heat tracing device for pipeline antifreeze. Background Technology
[0002] In winter, factories and enterprises need to use heat tracing to protect critical pipelines and instruments from freezing. Existing heat tracing methods include electric heat tracing, steam heat tracing, and hot water heat tracing. Among these, steam and hot water heat tracing result in greater heat loss, while electric heat tracing offers higher reliability and greater convenience.
[0003] In the existing technology, electric heat tracing devices used for pipeline antifreeze mainly involve laying electric heat tracing tape on the outside of the pipeline. When the electric heat tracing tape is energized, it converts electrical energy into heat energy, thereby heating the pipeline. However, since the width of the electric heat tracing tape is usually small, the contact area between the electric heat tracing tape and the pipeline is small, resulting in an unsatisfactory heating effect of the heat tracing pipe on the pipeline. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] In view of this, the purpose of this utility model is to propose an electric heat tracing device for pipeline antifreeze. The technical problem to be solved is that the width of the electric heat tracing tape is usually small, which results in a small contact area between the electric heat tracing tape and the pipeline, leading to an unsatisfactory heating effect of the heat tracing pipe on the pipeline.
[0006] (II) Technical Solution
[0007] To achieve the above-mentioned technical objectives, this utility model provides an electric heat tracing device for pipeline antifreeze:
[0008] It includes a pipe body, on the outside of which a silicone heat-conducting plate is provided. Two baffles are fixed to one side of the silicone heat-conducting plate, and an electric heating tape is provided to one side of the silicone heat-conducting plate. Multiple connecting plates are fixed between the two baffles. A cylinder is fixed to one side of the connecting plates. A cylindrical rod is slidably connected inside the cylinder. A U-shaped seat is fixed to the end of the cylindrical rod away from the cylinder. A pressure cylinder is rotatably connected inside the U-shaped seat. The electric heating tape can be placed between the two baffles and can pass through the silicone heat-conducting plate and the pressure cylinder.
[0009] As a preferred embodiment of the electric heat tracing device for pipeline antifreeze described in this utility model, the outer side of the cylinder has two guide grooves, and the outer side of the cylindrical rod has two guide rods fixed thereon, with the two guide rods slidingly engaged in the corresponding guide grooves.
[0010] As a preferred embodiment of the electric heat tracing device for pipeline antifreeze described in this utility model, an elastic element is provided inside the cylinder, one end of the elastic element abuts against the inner wall of the cylinder, and the other end of the elastic element abuts against the cylindrical rod.
[0011] In a preferred embodiment of the electric heat tracing device for pipeline antifreeze described in this utility model, the distance between the elastic element and the pressure cylinder and the silicone heat-conducting plate is less than the thickness of the electric heat tracing tape under normal conditions.
[0012] As a preferred embodiment of the electric heat tracing device for pipeline antifreeze described in this utility model, wherein: a plurality of connecting strips one are fixed at equal intervals on one side of the silicone heat-conducting plate, and a plurality of connecting strips two are fixed at equal intervals on the other side of the silicone heat-conducting plate; one side of the connecting strip one is provided with a rough surface, and one side of the connecting strip two is provided with a hook surface; the rough surface and the hook surface are bonded together.
[0013] As a preferred embodiment of the electric heat tracing device for pipeline antifreeze described in this utility model, the outer side of the pipeline body is covered with an insulation layer, which covers the silicone heat-conducting plate and the electric heat tracing tape, and the breaks in the insulation layer are sealed with adhesive tape.
[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:
[0015] 1: When the electric heating cable passes between the silicone heat-conducting plate and the pressure cylinder, the pressure cylinder is squeezed and will drive the cylindrical rod to move into the cylinder body, so that the cylindrical rod compresses the elastic element. When the electric heating cable is laid, the pressure cylinder can no longer play a limiting role, so that the electric heating cable can be fixed between the two baffles.
[0016] 2: After the electric heating cable is laid, the elastic rebound force of the elastic element allows the pressure cylinder to press against the electric heating cable, ensuring that the electric heating cable is tightly attached to the silicone heat-conducting plate. This allows the heat from the electric heating cable to be fully transferred to the silicone heat-conducting plate. The silicone heat-conducting plate has a large contact area with the pipe body, enabling it to better heat the pipe body and provide better antifreeze protection. Attached Figure Description

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.
[0024] Reference Figure 1-4 :
[0025] In one embodiment of this utility model, an electric heat tracing device for pipeline antifreeze is provided, including a pipeline body 1, a silicone heat-conducting plate 2 disposed on the outer side of the pipeline body 1, two baffles 3 fixed on one side of the silicone heat-conducting plate 2, an electric heat tracing tape 4 disposed on one side of the silicone heat-conducting plate 2, a plurality of connecting plates 5 fixed together between the two baffles 3, a cylinder 6 fixed on one side of the connecting plates 5, a cylindrical rod 7 slidably connected inside the cylinder 6, a U-shaped seat 8 fixed at the end of the cylindrical rod 7 away from the cylinder 6, a pressure cylinder 9 rotatably connected inside the U-shaped seat 8, the electric heat tracing tape 4 can be placed between the two baffles 3, and the electric heat tracing tape 4 can pass through the silicone heat-conducting plate 2 and the pressure cylinder 9.
[0026] The cylinder 6 is equipped with an elastic element 10. One end of the elastic element 10 abuts against the inner wall of the cylinder 6, and the other end of the elastic element 10 abuts against the cylindrical rod 7. Under normal conditions, the gap between the pressure cylinder 9 and the silicone heat-conducting plate 2 is less than the thickness of the electric heat tracing tape 4. The outer side of the pipe body 1 is covered with a heat insulation layer 17, which can cover the silicone heat-conducting plate 2 and the electric heat tracing tape 4.
[0027] It should be noted that the elastic element 10 can use a spring or other device. Since the gap between the pressure cylinder 9 and the silicone heat-conducting plate 2 is smaller than the thickness of the electric heating cable 4 when the electric heating cable 4 passes between the silicone heat-conducting plate 2 and the pressure cylinder 9, the pressure cylinder 9 can still press against the electric heating cable 4 under the rebound force of the elastic element 10. In addition, the break in the insulation layer 17 is bonded by tape 18.
[0028] Specifically, two guide grooves 11 are opened on the outer side of the cylinder 6, and two guide rods 12 are fixed on the outer side of the cylindrical rod 7. The two guide rods 12 are slidably engaged in the corresponding guide grooves 11. Multiple connecting strips 13 are fixed at equal intervals on one side of the silicone heat-conducting plate 2, and multiple connecting strips 25 are fixed at equal intervals on the other side of the silicone heat-conducting plate 2. A rough surface 14 is provided on one side of the connecting strip 13, and a hook surface 16 is provided on one side of the connecting strip 25. The rough surface 14 and the hook surface 16 are bonded together.
[0029] In use, first, attach the silicone heat-conducting plate 2 to the outside of the pipe body 1, then pull the connecting strap 15 to bond the hook surface 16 and the rough surface 14 together, thus fixing the silicone heat-conducting plate 2 to the pipe body 1. Then, place the electric heating tape 4 between the two baffles 3 and move the electric heating tape 4 to pass through the gap between the silicone heat-conducting plate 2 and the pressure cylinder 9. When the electric heating tape 4 passes through the gap between the silicone heat-conducting plate 2 and the pressure cylinder 9, it will squeeze the pressure cylinder 9 and drive the pressure cylinder 9 to rotate. After being squeezed, the pressure cylinder 9 will drive the U-shaped seat 8 and the cylindrical rod 7 to move. When the cylindrical rod 7 moves into the cylinder 6, The elastic element 10 is compressed. After the electric heating cable 4 is laid, the pressure cylinder 9 can no longer act as a limit, allowing the electric heating cable 4 to be fixed between the two baffles 3. At this time, under the rebound force of the elastic element 10, the pressure cylinder 9 can also press against the electric heating cable 4, allowing the electric heating cable 4 to adhere tightly to the silicone heat-conducting plate 2. This allows the heat from the electric heating cable 4 to be fully transferred to the silicone heat-conducting plate 2. Since the silicone heat-conducting plate 2 has a large contact area with the pipe body 1, it can better heat the pipe body 1 and play a role in preventing freezing.
[0030] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
