Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline insulation technology, and in particular to an insulation jacket with a heating function. Background Technology
[0002] Thermal insulation of process pipelines is a crucial component for ensuring smooth plant operations. In existing pipeline transportation, some media require high temperatures, necessitating the provision of heat during transport to prevent solidification and ensure smooth flow. Examples include transporting asphalt, adhesives, resins, and other chemicals, as well as heavy oil. In the past, these scenarios frequently resulted in poor heat tracing effects, uneven heating, and cross-contamination.
[0003] To address this problem, this utility model was developed. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a heat-insulating jacket with a simple structure that can provide heat to process pipelines and prevent the transported liquid from solidifying.
[0005] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a heat-insulating jacket with a heating function, comprising two heat-insulating jackets, wherein the heat-insulating jackets are provided with a wrapping channel matching the shape of the object to be insulated, and the object to be insulated is placed in the wrapping channel covered by the two heat-insulating jackets, wherein a connecting fixing device is provided between the heat-insulating jackets, and a heating device for heating is provided on the heat-insulating jackets.
[0006] A further improvement is that the heating device includes heating blocks that are matched with the number of insulation jackets. The heating blocks have their own internal heat medium channels. The heating blocks are provided with inlet pipes for steam / hot oil to enter the heat medium channels and outlet pipes to exit them. The insulation jackets have placement channels, and the heating blocks are placed in the placement channels. The inlet pipes and outlet pipes pass through the insulation jackets.
[0007] A further improvement is that the inner side of the package is coated with a thermally conductive adhesive layer.
[0008] A further improvement is that the thermally conductive putty layer is 2-3 mm thick.
[0009] A further improvement is that the heating block and the insulation jacket are integrally cast.
[0010] A further improvement is that the fixing device is provided with connecting ears on all four sides of the insulation jacket, and the connecting ears are connected by channel bolts.
[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0012] With a simple structure, it can heat the insulated object to prevent the transported medium from solidifying. The object is covered by an insulation jacket, which is then heated by steam / hot oil, thus heating the object. This prevents the asphalt and other media flowing through the pipeline from solidifying inside, ensuring the usability of the insulated object. It also avoids the cross-contamination that occurs with traditional jacketed heat tracing, guaranteeing smooth pipeline transport. Attached Figure Description
[0013] Figure 1 This is a cross-sectional structural diagram of a heat-insulating jacket with a heating function according to an embodiment of the present invention. Detailed Implementation
[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0015] refer to Figure 1 The present invention discloses a heat-insulating jacket with a heating function, comprising two heat-insulating jackets 2, wherein the heat-insulating jackets 2 are provided with a wrapping channel matching the shape of the object to be insulated 1, and the object to be insulated 1 is disposed within the wrapping channel covering the two heat-insulating jackets 2. The heat-insulating jackets 2 are provided with four connecting ears 3 around their perimeter, and the connecting ears 3 are connected by channel bolts 4. The heat-insulating jackets 2 are provided with a heating device for heating.
[0016] Specifically, the heating device includes heating blocks 6 arranged in a number matching the number of insulated objects 2. Each heating block 6 has its own internal heat medium channel. The heating block is equipped with an inlet pipe 7 for steam / hot oil to enter the heat medium channel and an outlet pipe 8 for exiting. The insulation jacket 2 has a placement channel 5, and the heating blocks 6 are placed within the placement channel 5. The heating blocks 6 and the insulation jacket 2 are integrally cast. The insulation jacket 2 covers the insulated object 1, and steam / hot oil is introduced through the inlet pipe 7, allowing the steam / hot oil to pass through the heat medium channel and then flow out from the outlet pipe 8. This causes the heating blocks 6 to heat up, transferring the heat to the insulation jacket 2, thus enabling the insulated object 1 to be heated. This prevents the asphalt or other media from solidifying inside the pipe, ensuring smooth media transport within the pipeline.
[0017] To improve thermal conductivity, a thermally conductive adhesive layer is applied to the inner side of the jacket.
[0018] Preferably, the thermally conductive adhesive layer is 3-5mm thick. By filling with the thermally conductive adhesive, not only can the heat transfer efficiency be increased, but the gap between the insulation jacket 2 and the insulation object 1 can also be filled, thereby allowing internal air to escape and further increasing the heat transfer efficiency, which is beneficial for heat transfer.
[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
