As shown in Figure 1, the utility model provides a kind of vacuum pipe deicing except dew device, suitable for straight vacuum pipe Vacuum pipe with crooked radian either combines any one of the above pipeline to be formed by flange pipe, vacuum tube It is wound with heated constant temperature band 2 in the form of equidistant or become spacing on the outer wall in road 1, heated constant temperature band 2 is tightly attached to vacuum pipe 1 Outer wall either pass through the outer wall that heat-conducting piece is supported on vacuum pipe 1.The deicing of this form is except dew apparatus structure is simple, system It causes this to tell somebody what one's real intentions are relatively, installs and safeguard and is also more convenient.

As shown in Figure 2 to 3, which further includes several being arranged along 1 length direction of vacuum pipe except device is revealed Thermally conductive item 3, it is corresponding that the outer wall of vacuum pipe 1 to heated constant temperature band 2 is separated into several jointly by thermally conductive item 3 as heat-conducting piece Heat preservation zone.These heat preservation zones are under the action of heated constant temperature band 2 and thermally conductive item 3, so that the heat of heated constant temperature band 2 is along vacuum Transfers while pipeline 1 circumferentially transmits improve deicing except the working efficiency of dew device, while also reducing heat damage It loses, ensure that vacuum pipe 1 under stationary temperature environment, avoids vacuum pipe and the phenomenon that the condensing that freeze occur always.

In order to guarantee the equilibrium of each heat preservation zone temperature of vacuum pipe 1, from the angle of production and use cost, thermally conductive item 3 quantity is at least 2, up to 6.

When vacuum pipe 1 is flange pipe, the side that thermally conductive item 3 is located at ring flange 10 is equipped with fixing seat 11, fixing seat Threaded hole corresponding with 10 upper flange hole of ring flange is offered on 11.By threaded hole, thermally conductive item 3 can be firmly secured at On the outer wall of vacuum pipe 1, it ensure that thermally conductive item 3 is constantly in contact condition with vacuum pipe 1, to ensure that heated constant temperature With 2 heat conduction efficiency.

As shown in figure 3, the thickness of thermally conductive item 3 is greater than the thickness of heated constant temperature band 2.Heated constant temperature band 2 is completely in this way Under thermally conductive item 3, the heat transfer of guarantee heated constant temperature band 2 is to vacuum pipe 1 as much as possible.

As shown in figure 4, thermally conductive item 3 is from top surface to bottom surface, its own width is successively increased.Thermally conductive 3 bottom surface of item is and vacuum The one side of 1 outer wall of pipeline contact, since the cryogenic media in vacuum pipe 1 makes its bottom surface temperature be lower than its top surface temperature certainly Degree, is always flowed to the principle of the side of low temperature according to heat by the side of high temperature, the heat transfer of heated constant temperature band 2 to thermally conductive item When 3, so that the outer wall of vacuum pipe 1 can be flowed to；And thermally conductive 3 bottom width of item is greater than top surface width, correspondingly, thermally conductive 3 bottom of item Face area is also greater than top surface area, increases the contact area of thermally conductive item 3 and vacuum pipe 1, accelerates heated constant temperature band 2 Flowing of the heat to vacuum pipe 1, and then increase the heat transfer efficiency of heat.

Preferably, thermally conductive item 3 is made of upper cover fillet 30 and lower cover fillet 31, offers confession between upper cover fillet 30 and lower cover fillet 31 The mounting hole 32 (in detail as shown in Figure 4) that heated constant temperature band 2 passes through.When installation, lower cover fillet 31 is first fixed on the outer wall of vacuum pipe 1 On, then heated constant temperature band 2 is caught on the mounting hole bottom surface 32b of lower 31 upper surface of cover fillet, cover fillet 30 is then installed, by The mounting hole top surface 32a of upper 30 lower end surface of cover fillet pushes down the fixation that heated constant temperature band 2 completes heated constant temperature band 2.Thermally conductive item 3 is divided It at upper cover fillet 30 and lower cover fillet 31, is only contacted, is reduced with heated constant temperature band 2 by the mounting hole top surface 32a of upper 30 lower end surface of cover fillet Convection current of the heat by upper cover fillet top surface 30a and air, to reduce the windage of the upward cover fillet top surface 30a of heat；Together When convenient disassembly, convenient for heated constant temperature band 2 later maintenance maintain.

Preferably, the bottom surface of lower cover fillet 31 is equipped with the water hole 31b that several groups are connected to its front and back side, several groups water hole 31b is spaced with mounting hole 32 on thermally conductive 3 length direction of item.The heat of heated constant temperature band 2 is passed through along mounting hole bottom surface 32b The arc binding face 31a crossed below passes to vacuum pipe 1, and water hole 31b gangs up each heat preservation zone, so that vacuum pipe Then the small unity dew that 1 outer wall is condensed due to liquefaction can be converged by water hole 31b forms agglomerate dew in itself weight Power effect is lower and drips, and further realizes deicing except the purpose of dew.

It obviously, is a part of the embodiment of the utility model described in above-described embodiment, instead of all the embodiments. Therefore, the component described and illustrated in the present embodiment attached drawing can be arranged and be designed with a variety of different configurations.It is right above The detailed description of the utility model embodiment provided in attached drawing is not intended to limit the range of claimed invention, But only indicate that the utility model selectes embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art exist Every other embodiment obtained under the premise of creative work is not made, is fallen within the protection scope of the utility model.
