[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.
[0021] This application provides a biphenyl device for a PET-ITY yarn production line, such as... Figure 1 As shown, the biphenyl device includes: an insulated box 10 and a biphenyl furnace 20.
[0022] like Figure 1-3 As shown, the insulated box 10 includes a retainer 1, a load-bearing base plate 2, a front cover plate 3, a rear cover plate 4, a first side cover plate 5, a second side cover plate 6, and a top cover plate 7. The retainer 1 is hexahedral in shape. The load-bearing base plate 2 covers the bottom surface of the retainer 1. The front cover plate 3 and the rear cover plate 4 cover the front and rear sides of the retainer 1, respectively, and the first side cover plate 5 and the second side cover plate 6 cover the left and right sides of the retainer 1, respectively, respectively. The top cover plate 7 covers the top surface of the retainer 1. The retainer 1, the load-bearing base plate 2, the front cover plate 3, the rear cover plate 4, the first side cover plate 5, the second side cover plate 6, and the top cover plate 7 together form a sealed enclosure, defining the shape of the insulated box 10.
[0023] The retainer 1 is made of carbon steel and is welded to ensure its sturdiness and support. The front cover 3, rear cover 4, first side cover 5, second side cover 6, and top cover 7 are all made of stainless steel, which has good corrosion resistance. The insulation box 10 also includes several support legs 8, which are fixedly installed on the underside of the load-bearing base plate 2 and arranged in pairs opposite each other. The height of each support leg 8 is greater than or equal to 50mm. The support legs 8 raise the height of the insulation box 10 from the ground, so that there is a gap of not less than 50mm between the load-bearing base plate 2 and the ground, which facilitates transportation by forklifts, pallet jacks, and other transportation tools, and makes it easier for customers without overhead cranes to lift, move, and place the box. In this embodiment, four support legs 8 are installed at the bottom of the load-bearing base plate 2, and the four support legs 8 form four fulcrum contacts with the ground, reducing the thermal conductivity and improving the insulation effect of the insulation box 10. The corners of the insulated box 10 are also wrapped with a layer of decorative angle iron to improve the aesthetics and insulation effect of the insulated box 10.
[0024] like Figure 2 , 3 As shown, the biphenyl furnace 20 includes a furnace body 9, a heating device 11, a temperature measuring device 12, a pressure measuring device 13, a hydraulic display device 14, and a rupture disc device 15. The furnace body 9, heating device 11, and temperature measuring device 12 are installed within the containment space. The pressure measuring device 13, hydraulic display device 14, and rupture disc device 15 are arranged on the outside of the insulation box 10. An insulation medium is filled between the furnace body 9 and the insulation box 10. The insulation medium is rock wool. In other embodiments, glass fiber, asbestos polystyrene foam, polyurethane foam, plant fibers, etc., can also be used. The insulation medium can be changed according to customer needs; different materials can meet different customer insulation requirements. The insulation medium not only insulates the biphenyl furnace 20 inside the insulation box 10 but also reduces heat transfer outwards, lowering the surface temperature of the insulation box 10 to a level that is touchable by the human body, thus reducing the danger of the high-temperature state of the biphenyl furnace 20 itself.
[0025] Heating device 11 is installed inside furnace body 9 to heat the biphenyl vapor entering furnace body 9. Temperature measuring device 12 includes several temperature sensors installed on furnace body 9 to monitor the temperature at corresponding locations in real time. Each temperature sensor has a temperature display panel exposed on the outside of insulation box 10, allowing operators to visually inspect the temperature inside furnace body 9. Pressure measuring device 13, hydraulic display device 14, and rupture disc device 15 are all connected to furnace body 9 via gas pipes. Pressure measuring device 13 monitors the gas pressure inside furnace body 9 in real time, hydraulic display device 14 monitors the liquid pressure inside furnace body 9 in real time, and rupture disc device 15 relieves pressure when there is overpressure inside furnace body 9. Pressure measuring device 13, hydraulic display device 14, and rupture disc device 15 are arranged on the outside of insulation box 10 for easy observation and maintenance of the biphenyl furnace 20's operating status, and also for easy replacement of easily damaged or consumable parts.
[0026] The top of the retainer 1 of the insulation box 10 is provided with multiple lifting ring holes, each of which can be used to install a lifting ring, which facilitates the overall movement of the biphenyl unit by vehicles, thereby improving the flexibility of the biphenyl unit transfer.
[0027] The insulation box 10 makes full use of the limited space around the biphenyl furnace 20, reduces the workload of covering the rare earth insulation layer on site, and eliminates the need to damage the rare earth insulation layer when repairing the biphenyl furnace 20. This standardizes the layout of the biphenyl furnace 20 and reduces the workload during repair and replacement, thereby achieving the goal of cost reduction and efficiency improvement.
[0028] The biphenyl furnace 20 of this application is installed inside the insulation box 10 and becomes an integral part of the insulation box 10. It has good insulation performance and is easy to install, maintain and replace, reducing construction difficulty and workload, shortening the construction cycle, and effectively reducing manpower, material resources and time costs.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
