Description

Technical Field

[0001] This utility model relates to the field of electric heat tracing technology, and in particular to an antifreeze and cold-resistant electric heat tracing cable for pipelines. Background Technology

[0002] Pipeline electric heating tape is an electric heating element mainly composed of a conductive polymer, two parallel metal wires, and an insulating sheath. It is used in industrial water pipes, water supply and drainage pipes, sewage pipes, etc., to solve the problem of pipe freezing and blockage in winter.

[0003] Existing pipe electric tracing cables are generally single cables fixed to pipes using tape or similar methods. However, due to the small diameter and limited heat-conducting area of ​​these cables, a large portion of the pipe is exposed to the external environment when fixed. The heat generated by the cable dissipates through the pipe and the cable itself into the external environment, resulting in poor heating efficiency. Furthermore, existing cables are typically secured to pipes with cable ties or tape, which is cumbersome. Therefore, we propose a freeze-resistant and cold-resistant pipe electric tracing cable. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a freeze-proof and cold-resistant electric heating tape for pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe antifreeze and cold-resistant electric heating tape is designed, including a heat insulation sleeve, a heating cable is provided inside the heat insulation sleeve, and the heating cable includes a wire core and an insulation layer fixed on the outer surface of the wire core;

[0006] A heat-conducting sleeve is also installed on the outer surface of the heating cable, and a heat-conducting film is connected to the bottom of the heat-conducting sleeve. When the heating cable is wrapped around the pipe, the heat-conducting film contacts the side wall of the pipe.

[0007] The outer surface of the heat-conducting sleeve is fixed to the inner surface of the heat-insulating sleeve. A heat-insulating plate is installed at the bottom of the heat-insulating sleeve, and a receiving groove is opened at the bottom of the heat-insulating plate, in which the heat-conducting sheet is located.

[0008] Both ends of the heating cable are equipped with connecting sleeves. The sides of the connecting sleeves are respectively equipped with a first fixing strap and a second fixing strap. The end of the second fixing strap is connected to a buckle. Several mounting holes are opened on the side of the first fixing strap. One end of the first fixing strap passes through the buckle, and the locking pin of the buckle passes through the corresponding mounting hole.

[0009] Preferably, the thermally conductive film extends to the outside of the heating cable on both sides.

[0010] Preferably, both the thermally conductive sleeve and the thermally conductive sheet are made of thermally conductive silicone material.

[0011] Preferably, the bottom of the thermally conductive film is flush with the bottom opening of the receiving groove.

[0012] Preferably, the heat insulation plates are in contact with each other at adjacent edges when the heating cable is spirally wound around the pipe.

[0013] Preferably, both the insulation board and the insulation sleeve are made of aerogel material.

[0014] Preferably, one end of the heating cable is connected to a switch via a wire, and the switch is also connected to a power source via a wire.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. The heat-conducting sleeve and heat-conducting film can increase the heat-conducting area of ​​the heating cable, and the heat-insulating sleeve and heat-insulating plate can reduce the rate at which the heat generated by the heating cable is lost to the external environment, thereby improving the heating effect.

[0017] 2. By using the first and second fixing straps together, both ends of the heating cable can be fixed to the pipe, making fixing convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4A type of antifreeze and cold-resistant electric heating cable for pipelines includes a heat insulation sleeve 8. The heat insulation sleeve 8 is equipped with a heating cable 1. The heating cable 1 includes a wire core 13 and an insulation layer 12 fixed on the outer surface of the wire core 13. In actual use, the insulation layer 12 can provide insulation protection for the wire core 13 and prevent the wire core 13 from short-circuiting.

[0025] It should be noted that, as shown in the figure, one end of the heating cable 1 is connected to a switch 9 via a wire. The switch 9 is also connected to a power source via a wire. The operation of the heating cable 1 can be controlled by the switch 9, so that the heating cable 1 can work normally.

[0026] like Figure 1 As shown, a heat-conducting sleeve 14 is also installed on the outer surface of the heating cable 1. A heat-conducting film 10 is connected to the bottom of the heat-conducting sleeve 14. When the heating cable 1 is wrapped around the pipe, the heat-conducting film 10 contacts the side wall of the pipe. Both the heat-conducting sleeve 14 and the heat-conducting film 10 are made of heat-conducting silicone material. In actual use, the heat generated by the heating cable 1 will be transferred to the pipe through the heat-conducting sleeve 14 and the heat-conducting film 10 to heat the pipe.

[0027] like Figure 1 and Figure 4 As shown, the outer surface of the heat-conducting sleeve 14 is fixed to the inner surface of the heat-insulating sleeve 8. A heat-insulating plate 5 is installed at the bottom of the heat-insulating sleeve 8. A receiving groove 11 is opened at the bottom of the heat-insulating plate 5, and the heat-conducting film 10 is located in the receiving groove 11. Both the heat-insulating plate 5 and the heat-insulating sleeve 8 are made of aerogel material. In actual use, the heat transferred by the heat-conducting sleeve 14 and the heat-conducting film 10 can be separated by the heat-insulating sleeve 8 and the heat-insulating plate 5, reducing the rate at which heat is lost to the external environment and improving the heat preservation effect.

[0028] like Figure 4 As shown, the bottom of the thermally conductive film 10 is flush with the bottom opening of the receiving groove 11. This way, after the heating cable 1 is spirally wound on the pipe, the thermally conductive film 10 will be in full contact with the pipe surface, improving the heating effect.

[0029] like Figure 1 and Figure 2 As shown, both ends of the heating cable 1 are equipped with connecting sleeves 2. The sides of the connecting sleeves 2 are respectively equipped with a first fixing band 3 and a second fixing band 7. The end of the second fixing band 7 is connected to a buckle 6. Several mounting holes 4 are opened on the side of the first fixing band 3. One end of the first fixing band 3 passes through the buckle 6, and the locking pin of the buckle 6 passes through the corresponding mounting hole 4. In actual use, after the heating cable 1 is spirally wound on the pipe, the operator can fix both ends of the heating cable 1 to the pipe by the cooperation of the first fixing band 3 and the second fixing band 7, which is convenient.

[0030] Specifically, in use, the operator spirally winds the heating cable 1 around the pipe, so that the heat-conducting sheet 10 contacts the outer surface of the pipe. After winding, the operator extends the first fixing strap 3 and the second fixing strap 7 to both sides of the pipe, and then passes one end of the first fixing strap 3 through the locking buckle 6. After the first fixing strap 3 and the second fixing strap 7 are tightly wrapped around the pipe, the locking pin on the locking buckle 6 is passed through the corresponding mounting hole 4 to fix the heating cable 1 to the pipe. In use, the operator controls the operation of the heating cable 1 through the switch 9. The heat generated by the heating cable 1 is transferred to the surface of the pipe through the heat-conducting sleeve 14 and the heat-conducting sheet 10 to heat the pipe. Furthermore, the heat generated by the heating cable 1 can be isolated from the external environment by the heat insulation sleeve 8 and the heat insulation plate 5, reducing heat loss and improving the heating effect.

[0031] Furthermore, such as Figure 4 As shown, the thermally conductive film 10 extends to the outside of the heating cable 1 on both sides, which increases the contact area between the thermally conductive film 10 and the pipe and improves the heating effect.

[0032] Furthermore, such as Figure 3 As shown, when the heating cable 1 is spirally wound around the pipe, the heat insulation plate 5 is connected in close contact with the adjacent edges, which can isolate the outer surface of the pipe from the external environment and reduce the rate of heat loss.

[0033] 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.
