[0001] The utility model relates to the technical field of pipeline heating in a production process, in particular to a pipeline heating device used for the production of semi-finished products of absorbing materials. Background Art

[0002] Absorbing material is a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves. It not only has the absorbing properties of anti-electromagnetic interference, microwave directional enhancement, and clutter suppression, but also takes into account high and low temperature resistance, load-bearing and other properties.

[0003] During the production process of absorbing materials, the materials are usually heated and dispersed evenly in a mixer, then pressurized and transported through pipelines. Finally, they are injected into a mold, heated, and solidified to form a block of absorbing materials. This production process has the following defects and shortcomings:

[0004] 1) When the material is heated and evenly dispersed by the mixer and flows through the pipeline for injection, the temperature of the material will inevitably decrease, resulting in an increase in its viscosity, which increases the difficulty of pressurized transportation of the material;

[0005] 2) When the material temperature drops and its viscosity increases, its fluidity deteriorates significantly, which easily leads to material deposition inside the pipeline, thereby blocking the pipeline and causing one-time waste of material.

[0006] Therefore, there is an urgent need in the prior art to invent a pipeline heating device that can reduce the difficulty of transporting absorbing materials and avoid pipeline blockage. Utility Model Content

[0015] In this solution, the heating unit includes an extension segment and a connecting segment, and the connecting segment connects adjacent extension segments so that the heating unit is arranged in a bow shape.

[0016] The extension section extends along the first direction of the wrapping layer so that when the wrapping layer wraps the pipe, the extension section is extended along the circumferential direction of the pipe; the connecting section extends along the second direction of the wrapping layer so that when the wrapping layer wraps the pipe, the connecting section is extended along the axial direction of the pipe.

[0017] Furthermore, the heating unit includes a flexible resistance wire, and the flexible resistance wire is fixedly arranged on the heat conducting layer and / or the heat insulating layer.

[0018] In another optional solution of the present invention, a specific structural design of the wrapping layer and the connecting piece is provided.

[0019] In this solution, the connecting piece is a Velcro, which is arranged on the side of the protective layer away from the heat-conducting layer. When the wrapping layer wraps the pipe, it is fixedly connected by adhesion of the Velcro.

[0042] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] See also Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, a pipe heating device for producing absorbing materials includes a wrapping layer and a heating unit 1. The wrapping layer comprises a heat-conducting layer 2, a heat-insulating layer, and a protective layer 4, arranged in sequence. The heating unit 1 is disposed between the heat-conducting layer 2 and the heat-insulating layer. The wrapping layer can be wrapped around the outer circumference of the pipe. After wrapping the pipe, the heat-conducting layer 2 and the pipe are positioned adjacent and in close contact. When the injection pipe is not wrapped, the wrapping layer is a multi-layered planar structure, with the heating unit 1 disposed within the wrapping layer. During use, the wrapping layer can be adjusted to fit injection pipes of varying shapes and sizes, providing easy operation and strong adaptability.

[0046] More specifically, the heat-conducting layer 2 and the heating unit 1 are fitted together. When the heating unit 1 is started, the heat generated by the heating is transferred to the material in the pipeline through the heat-conducting layer 2. The heating of the heating unit 1 and the heat conduction of the heat-conducting layer 2 cause the flowing material inside the pipeline to be heated and kept warm, which can prevent the material from cooling in the pipeline, resulting in increased viscosity and material deposition, thereby reducing the difficulty of transporting the absorbing material and avoiding blockage of the injection pipeline.

[0047] In addition, the present invention can avoid direct contact between the heating unit 1 and the outside of the pipe by setting up the heat-conducting layer 2, thereby avoiding the problem of uneven heating of the pipe leading to local excessive temperature, and avoiding high temperature in the pipe area where heat is concentrated, which may cause damage to the pipe.

[0048] The pipeline heating device for producing absorbing materials also includes connectors (not shown). These connectors are disposed on the protective layer 5, specifically on the sides of the protective layer 5 facing away from the exterior of the pipeline. These connectors connect the two sides of the wrapping layer when it is wrapped around the pipeline. Specifically, the wrapping layer utilizes a non-closed design. After the wrapping layer wraps around the pipeline, the connectors securely connect the two sides, securing the wrapping layer to the pipeline. This facilitates assembly and disassembly, further improving compatibility with different pipelines.

[0049] In this embodiment, the heating unit 1 is arranged in a bow-shaped configuration. This structural design facilitates the bending of the heating unit 1 and its attachment to the heat-conducting layer 2 when the wrapping layer is wrapped around the pipe, allowing heat to be transferred to the pipe through the heat-conducting layer 2. Furthermore, the bow-shaped arrangement increases the contact area between the heating unit 1 and the heat-conducting layer 2, thereby improving the heating effect and efficiency of the pipe. Once the heating unit is activated, it can quickly and efficiently heat the pipe.

[0050] Example 1

[0051] In an optional embodiment of the present invention, a technical solution for the specific structural design of the heating unit is provided.

[0052] See also Figure 3 As shown, in the technical solution of this embodiment, the heating unit 1 includes an extension segment 11 and a connecting segment 12. The connecting segment 12 is used to connect adjacent extension segments 11, so that the heating unit 1 is arranged in a bow shape. Specifically, the extension segments 11 extend along a first direction of the wrapping layer, so that when the wrapping layer is wrapped around the pipe, the extension segments 11 extend along the circumferential direction of the pipe. The connecting segment 12 extends along a second direction of the wrapping layer, so that when the wrapping layer is wrapped around the pipe, the connecting segment 12 extends along the axial direction of the pipe.

[0053] See Figure 3As shown, the first direction described in this embodiment is Figure 3 The X-axis direction shown in FIG, the second direction described in this embodiment is Figure 3 When installing the pipe heating device of the present invention, the wrapping layer is bent along the X-axis and fitted around the pipe. The connectors provided on both sides of the wrapping layer extending along the Y-axis are then fixedly connected, thereby connecting the two sides of the wrapping layer extending along the Y-axis, completing the wrapping operation on the pipe. After the wrapping is installed, the extension section 11 extends circumferentially along the pipe, and the connecting section 12 extends axially along the pipe.

[0054] The above-described structural design allows for the longer extension segments 11 to extend circumferentially along the pipe and be spaced apart along its length. Each extension segment 11 is connected by a connecting segment 12. The heating effect of the extension segments 11 allows for uniform heating of the pipe, thereby avoiding uneven heating that can lead to localized overheating and preventing high temperatures in concentrated heat areas that could damage the pipe. Furthermore, the distances between each extension segment 11 can be set equal, further improving heating uniformity.

[0055] In a preferred embodiment of this embodiment, the heating material of the heating unit 1 can preferably be a high-temperature resistance wire. When energized, the electrical energy is converted into thermal energy to achieve a heating effect on the pipeline. The installation position of the resistance wire can be determined according to the specific situation. It can be fixedly installed on the heat-conducting layer 2, the heat-insulating layer 3, or both the heat-conducting layer 2 and the heat-insulating layer 3, thereby achieving a fixed position on the heat-conducting layer 2 and the heat-insulating layer 3.

[0056] Example 2

[0057] In another optional embodiment of the present invention, a technical solution for the specific structural design of the wrapping layer and its connecting parts is provided.

[0058] In an alternative embodiment of this embodiment, the connector can be a Velcro strip. The Velcro strip is positioned on the side of the protective layer 5 facing away from the heat-conducting layer 2. When the wrapping layer is wrapped around the pipe, the two sides of the wrapping layer are fixedly connected by the Velcro strip. Specifically, the Velcro strip used in this embodiment can be divided into two parts: a fleece-side Velcro strip and a thorn-side Velcro strip, which are used in conjunction with each other. The two parts are respectively positioned on the two sides of the wrapping layer extending along the Y-axis. After the wrapping layer is wrapped around the pipe, the fleece-side Velcro strip and the thorn-side Velcro strip are attached together, allowing for easy assembly. When disassembly is required, the fleece-side Velcro strip and the thorn-side Velcro strip can be separated, making the operation simple and convenient.

[0059] In another optional solution of this embodiment, the heat-conducting layer 2 may be made of a material with good thermal conductivity and high-temperature resistance. In this embodiment, heat-conducting silicone cloth is preferably used.

[0060] See also Figure 2 As shown, in another optional solution of this embodiment, the thermal insulation layer includes a first thermal insulation layer 3 disposed adjacent to the heating unit 1. Specifically, since the first thermal insulation layer 3 and the heating unit 1 are disposed directly adjacent to each other, in order to avoid fire and to provide thermal insulation, the first thermal insulation layer 3 is preferably made of a material having both flame retardant and thermal insulation properties.

[0061] In particular, the first heat insulating layer 3 may preferably be made of glass fiber material, which has the characteristics of low thermal conductivity and non-flammability.

[0062] Further, see Figure 2 As shown, the thermal insulation layer also includes a second thermal insulation layer 4 arranged adjacent to the first thermal insulation layer 3. The second thermal insulation layer 4 is used to further provide a thermal insulation effect on the basis of the first thermal insulation layer 3, reduce the energy loss caused by the heat emitted by the heating unit 1 diffusing outward, and at the same time play an anti-scalding role, thereby improving the safety performance in the production process of the absorbing material.

[0063] In particular, the second thermal insulation layer 4 may preferably be made of thin flexible aerogel felt, which has the characteristics of low thermal conductivity, light weight, softness, hydrophobicity and good high temperature resistance.

[0064] In another optional solution of this embodiment, the protective layer 5 is the outermost structure of the wrapping layer behind the pipe, which is used to provide structural protection such as dustproof and waterproof. In particular, the protective layer 5 can be made of PVC waterproof cloth.

[0065] Example 3

[0066] In another optional embodiment of the present invention, a technical solution is provided on how to realize temperature measurement and temperature control functions.

[0067] See also Figure 1 and Figure 3 As shown, in the technical solution of this embodiment, the pipeline heating device for producing absorbing materials also includes a control module 7, which is electrically connected to the heating unit 1 and is equipped with a gear adjustment device (not shown). Specifically, the control module 7 is used to control the activation and deactivation of the heating unit 1, as well as specific temperature adjustment operations. By adjusting the temperature, the heat generated by the heating unit 1 is matched to the required temperature of the material in the pipeline. More specifically, the gear adjustment device of the control module 7 allows the user to set multiple desired temperature gears, such as 45°C, 60°C, 75°C, and so on, thereby controlling the different temperatures that the heating unit 1 can reach, thereby enhancing the intelligence of the device.

[0068] See also Figure 1 As shown, in a preferred embodiment of this embodiment, the pipeline heating device for producing absorbing materials further includes at least one temperature probe 6. One or more temperature probes 6 are positioned on the side of the heat-conducting layer 2 away from the heating unit 1 and are electrically connected to a control module 7 via a wire 61. Specifically, after the wrapping layer is wrapped around the pipeline, the temperature probe 6 is positioned flush against the outside of the pipeline, thereby directly measuring the actual pipeline temperature, that is, the temperature of the material flowing within the pipeline. When the pipeline temperature reaches the temperature set by the gear adjustment device, the temperature probe 6 transmits an electrical signal to the control module 7, which controls the heating unit 1 to maintain the preset temperature. The pipeline heating device enters the insulation phase, and the temperature no longer increases.

[0069] In summary, the pipeline heating device of the present invention includes a wrapping layer and a heating unit 1. During the production process of the absorbing material, the wrapping layer is wrapped around the outer periphery of the injection pipe. Heating by the heating unit 1 and heat conduction by the heat-conducting layer 2 promotes the temperature rise and insulation of the flowing material inside the pipe. This prevents the material from cooling within the pipe, which would lead to increased viscosity and material deposition. This reduces the difficulty of transporting the absorbing material and avoids clogging of the injection pipe. Furthermore, the heating unit 1 is arranged in a bow-shaped configuration, allowing it to be easily bent and attached to the heat-conducting layer 2 when the wrapping layer is wrapped around the pipe, allowing heat to be transferred to the pipe through the heat-conducting layer 2. This bow-shaped design also increases the contact area between the heating unit 1 and the heat-conducting layer 2, thereby improving the heating effect and efficiency. Once the heating unit 1 is activated, it can quickly and efficiently complete the heating operation of the pipe. Furthermore, the wrapping layer adopts a stacked planar design, with the heating unit 1 disposed within the wrapping layer. During use, the wrapping and attachment can be adjusted to suit pipes of different shapes and sizes, providing convenient operation and strong adaptability. At the same time, the wrapping layer adopts a non-closed design. After the wrapping layer wraps the pipe, it is fixedly connected through connectors, which is convenient for users to assemble and disassemble, and can further improve the adaptability to different pipes.

[0070] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
