Description

Technical Field

[0001] This application relates to the field of chemical fiber spinning equipment technology, and in particular to an adjustable melt pipeline component. Background Technology

[0002] Currently, most practitioners in related industries in China use on-site manual welding to ensure precision in fitting and installation. However, due to the existing technical capabilities of these practitioners, on-site manual welding or direct welding of rigid pipes eliminates the versatility, consistency, and ease of maintenance of the molten metal piping. When metering pumps and their associated piping malfunction and require repair, testing, or replacement, manual welding is the only solution, wasting significant manpower and resources and causing substantial downtime in the production workshop. Furthermore, during disassembly and repair, the manual welding process eliminates the need for interchangeable parts, requiring individual matching and leading to waste and pressure on spare parts. Summary of the Invention

The pair of main connecting flanges are arranged on opposite sides.

[0006] A pair of heat medium pipelines are respectively connected to the heat medium channel of the main pipeline. Each heat medium pipeline includes an outer heat medium pipe and a branch connection flange. One end of the outer heat medium pipe is connected to the outer pipe of the main pipeline and is in fluid communication with the heat medium channel. The branch connection flange is installed at the other end of the outer heat medium pipe.

[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] like Figure 1-3 As shown in the first embodiment, this application provides an adjustable melt pipeline component, which includes: a main pipeline 1 and a pair of heat medium pipelines 2. The main pipeline 1 is connected between an extrusion device and a spinneret, and the pair of heat medium pipelines 2 are respectively connected between the main pipeline 1 and a heat medium source.

[0022] like Figure 1-4 As shown, the main pipeline 1 includes a main pipeline outer pipe 11, a main pipeline expansion joint 12, a pair of main pipeline connecting flanges 13 respectively installed at both ends of the main pipeline outer pipe 11, and a flexible pipe 14 passing through the main pipeline outer pipe 11. The pair of main pipeline connecting flanges 13 are installed at both ends of the main pipeline outer pipe 11 and are arranged in opposite directions, which facilitates the connection of the pair of main pipeline connecting flanges 13 to equipment at different locations, and allows the main pipeline 1 to be detachably connected to upstream and downstream equipment, which facilitates disassembly and subsequent maintenance, shortens maintenance and replacement time, and avoids long-term machine downtime. Each main pipeline connecting flange 13 is provided with a flexible metal gasket 3. When the connection surface is irregular or slightly deformed, the flexible metal gasket 3 can seal between the connection surface and the main pipeline connecting flange 13 to prevent leakage.

[0023] The main pipeline 11 includes two main branch pipelines 111. A main expansion joint 12 connects the two adjacent main branch pipelines 111. The two main branch pipelines 111 are arranged perpendicular to each other to facilitate the connection of equipment at different heights and positions. The main expansion joint 12 allows the two main branch pipelines 111 to be offset from each other by a certain angle and distance, thereby adapting to different installation conditions and reducing the pressure on spare parts.

[0024] The two ends of the flexible tube 14 are respectively connected to a pair of main line connection flanges 13. When the main line connection flanges 13 are connected to the corresponding equipment, one end of the flexible tube 14 is connected to the extrusion port of the extrusion equipment, and the other end of the flexible tube 14 is connected to the feed port of the spinneret. The flexible tube 14 supplies the spinning melt output from the extrusion equipment to the spinneret. The flexible tube 14 is made of stainless steel to ensure melt delivery and temperature transfer. The flexible tube adopts an internally electropolished bent tube structure. When the angle of the two main line branch pipes 111 is adjusted, the flexible tube 14 deforms to adapt to the installation of the main line outer pipe 11. The diameter of the flexible tube 14 is smaller than that of the main outer tube 11. The main outer tube 11 is wrapped around the flexible tube 14. On the one hand, it is used to protect the flexible tube 14. On the other hand, a heat medium channel 15 for transporting the heat medium is formed between the outer wall of the flexible tube 14 and the inner wall of the main outer tube 11. The heat medium in the heat medium channel 15 is used to keep the spinning melt transported in the flexible tube 14 warm, so as to prevent the spinning melt from cooling down and solidifying during the transport process, which would cause pipeline blockage.

[0025] Each heat medium pipeline 2 includes a heat medium outer pipe 21 and a branch connection flange 22. One end of the heat medium outer pipe 21 is connected to the main outer pipe 11 and is in fluid communication with the heat medium channel 15. The branch connection flange 22 is installed at the other end of the heat medium outer pipe 21, allowing the heat medium pipeline 2 to be detachably connected to the heat medium source. One heat medium pipeline 2 is used to transport the heat medium from the heat medium source to the heat medium channel 15 of the main pipeline 1, and the other heat medium pipeline is used to transport the heat medium in the heat medium channel 15 back to the heat medium source for reheating. A pair of heat medium pipelines 2 are used to circulate the heat medium, so that the heat medium in the heat medium channel 15 is maintained within a preset temperature range, ensuring the temperature of the spinning melt transported in the flexible tube 14.

[0026] To facilitate the connection between the heat medium pipeline 2 and the heat medium source, each heat medium pipeline 2 also includes a branch expansion joint 23. The heat medium outer pipe 21 includes two heat medium branch pipes 211, and a branch expansion joint 23 is connected between the two heat medium branch pipes 211. The two heat medium branch pipes 211 are arranged perpendicular to each other, and the connection between the branch connecting flange 22 and the heat medium source is adjusted by the branch expansion joint 23.

[0027] like Figure 5 , 6 As shown, in the second embodiment, based on the melt pipeline components of the first embodiment, the main pipeline 1' further includes a measuring head 4. The measuring head 4 is installed on one of the main pipeline branch pipes 111'. The measuring head 4 is connected to the flexible pipe 14' to measure the temperature, flow rate and pressure of the spinning melt in the flexible pipe 14'. After detecting the parameters of the spinning melt, the conveying speed and flow rate can be adjusted according to the detection results to improve the spinning quality of the spinning equipment.

[0028] The melt piping components of this application can be detachably installed between two adjacent devices, which improves disassembly and assembly efficiency, shortens maintenance and replacement time, and increases the versatility of melt piping components, reducing the spare parts pressure for customers.

[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.
