Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pipeline heating, in particular to an L-shaped vacuum pipeline using a series structure heating jacket. Background Art

[0002] In many industrial applications, L-shaped vacuum tubes are used to transport low-temperature gases. However, under low-temperature conditions, the gas is prone to crystallization, resulting in the gas condensing in the pipeline and adhering to the pipeline wall, eventually causing pipeline blockage. This problem not only affects the normal transportation of the gas but also increases the frequency and cost of maintaining and cleaning the pipeline. Therefore, a heating device is used to heat the pipeline.

[0003] However, the existing heating devices have some drawbacks: Most traditional heating devices use a whole heating sleeve. Therefore, when the heating device fails, it is difficult to detect and handle it in time, which may lead to a decrease in the pipeline temperature and further exacerbate the crystallization phenomenon. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an L-shaped vacuum pipeline using a series structure heating jacket, which can avoid the situation that most traditional heating devices use a whole heating sleeve. Therefore, when the heating device fails, it is difficult to detect and handle it in time, which may lead to a decrease in the pipeline temperature and further exacerbate the crystallization phenomenon.

[0005] The utility model provides an L-shaped vacuum pipeline using a series structure heating jacket, which includes a plurality of heating jacket bodies wrapping the pipeline. Adjacent two heating jacket bodies are connected in series through a connector. At the same time, a resistance wire is installed inside the heating jacket body. After the resistance wire in one heating jacket body is powered on, the temperature of the whole circuit is controlled by one section of the heating jacket body to achieve temperature control.

[0015] Compared with the prior art, the L-shaped vacuum pipeline provided by the embodiment of the present invention uses a series-structured heating jacket:

[0016] 1.

[0030] Please refer to Figures 1-8 , the embodiment of the present utility model provides a series-connected structure heating jacket for an L-shaped vacuum pipeline, which includes a plurality of heating jacket bodies 1 wrapping the pipeline. Adjacent two heating jacket bodies 1 are connected in series through a connector 2. The plurality of heating jacket bodies 1 are connected in series. When one or more heating jacket bodies 1 fail, the entire circuit will power off and cool down. When the temperature drops below the low-temperature warning value, the device will issue a fault warning (a temperature sensor and an audible and visual alarm can be installed on the heating jacket body 1 for fault warning), so that the fault location can be quickly found.

[0031] Meanwhile, a heating wire 3 is installed inside the heating jacket body 1. After the heating wire 3 in one of the heating jacket bodies 1 is powered on, the temperature of the entire circuit is controlled by one section of the heating jacket body 1 to achieve temperature control, and the required heating temperature is selected by adjusting the temperature on the controller.

[0032] For easy disassembly and assembly, a set of Velcro one 4 is provided on the heating jacket body 1, and the heating jacket body 1 is wrapped around the pipeline through the Velcro one 4.

[0033] In addition, the heating jacket body 1 is made of Teflon material, which has excellent resistance to atmospheric aging and non-combustibility, and other materials inside the heating jacket body 1 also have high temperature resistance.

[0034] Furthermore, fixing sleeves 5 are installed on two adjacent heating jacket bodies 1, and an elastic sleeve 12 is connected between the two fixing sleeves 5. The elastic sleeve 12 seals the connection part of the two adjacent heating jacket bodies 1 to prevent the internal temperature of the heating jacket body 1 from leaking and improve its heat preservation effect.

[0035] The outer side of the fixing sleeve 5 is provided with a Velcro rough surface 8, and the upper and lower ends of the inner side of the elastic sleeve 12 are provided with Velcro hook surfaces 13. The Velcro rough surface 8 and the Velcro hook surface 13 are pasted together, which is convenient for disassembling and assembling the elastic sleeve 12 and can be used according to requirements.

[0036] The front and back sides of the elastic sleeve 12 are provided with Velcro two 14, and the elastic sleeve 12 forms an annular structure through the Velcro two 14 to further improve its sealing effect.

[0037] Even further, two opposite inner sleeves 6 are provided inside the fixing sleeve 5. The inner sleeve 6 and the fixing sleeve 5 are connected by a spring 7. The inner sleeve 6 is attached to the heating jacket body 1. When the fixing sleeve 5 is tightened by force, the spring 7 buffers the force to prevent the inner sleeve 6 from damaging the heating jacket body 1.

[0038] A U-shaped buckle 10 is provided on the outer side of the opening part of the fixing sleeve 5, and a sliding strip 11 is provided on the inner side of the U-shaped buckle 10. When the sliding strip 11 is in sliding fit with the sliding grooves 9 opened on both sides of the opening of the fixing sleeve 5, the U-shaped buckle 10 is installed at the opening of the fixing sleeve 5. At this time, the fixing sleeve 5 is tightened, so that the inner sleeve 6 is closely attached to the outer side of the heating jacket body 1, and the heating jacket body 1 heats the pipeline more stably.

[0039] In summary, the L-shaped vacuum pipeline of the embodiment of the present utility model uses a series structure heating jacket. The working principle is: multiple heating jacket bodies 1 are wrapped around the pipeline to heat the pipeline, so that the gas is not easy to crystallize, thereby reducing the number of pipeline cleaning times, and adjacent heating jacket bodies 1 are connected by a connector 2. The entire circuit is controlled by one section of the heating jacket body 1 to achieve temperature control. When multiple heating jacket bodies 1 are connected in series, when one or more heating jacket bodies 1 fail, the entire circuit will power off and cool down. When the temperature drops below the low-temperature warning value, the device will issue a fault warning.
