Description

Technical Field

[0001] This utility model relates to the field of fluid conveying technology in the textile industry, specifically to a multifunctional distribution device suitable for conveying viscous fluids, especially suitable for distributing high-viscosity fluids in a new solvent-based cellulose fiber dope production line. Background Technology

[0002] After being pumped out, the new solvent-based cellulose fiber solution needs to be transported to the spinning equipment. The traditional conveying pipeline connecting the pump and the spinning equipment is a cylindrical pipe. Because the new solvent-based cellulose fiber solution is a relatively high-viscosity liquid, laminar flow occurs during transport through this cylindrical pipe. This means the solution does not flow in a uniform liquid state within the pipe, resulting in inconsistent and uncontrollable parameters such as flow velocity, temperature, pressure drop, and residence time at different positions within the pipe. In other words, the viscosity and other properties of the fiber solution cannot remain relatively stable during its transport along the cylindrical pipe to the spinning machine, nor can it be evenly distributed to the various spinning components within the machine, thus failing to provide the necessary foundation for uniform spinning in each spinning assembly.

[0003] If the pipeline connection between the booster pump and the spinning machine is removed, and the booster pump outlet is directly connected to the spinning machine, and then several outlets are branched off to connect to the spinning components, although laminar flow is avoided, the fiber solution pressurized by the booster pump will be directly split at high speed without any buffering or transition, which will cause the spinning components at the end to be unable to spin. Therefore, the idea of ​​removing the pipeline connection between the booster pump and the spinning machine and directly connecting the booster pump outlet to the spinning machine is not feasible.

[0004] Therefore, it is necessary to improve the connection pipeline between the booster pump and the spinning machine. This would not only buffer the fiber solution after it has been pressurized by the booster pump, allowing the fiber solution extruded by the booster pump to be safely and smoothly delivered to the spinning machine while maintaining relatively stable properties such as viscosity, but also ensure that it is evenly distributed to each spinning assembly in the spinning machine. This would provide a prerequisite for achieving uniform spinning in each spinning assembly. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing a multifunctional distribution device suitable for conveying viscous fluids. This invention enables the safe and smooth delivery of the fiber solution extruded from the booster pump to the spinning machine while maintaining relatively stable viscosity and other properties, thus ensuring uniform spinning for each spinning assembly. Furthermore, this invention is compatible with spinning machines of different capacities and has the advantages of strong versatility and wide applicability.

[0006] The objective of this utility model can be achieved using the following technical solutions: This utility model discloses a multifunctional distribution device suitable for conveying viscous fluids. It comprises a double-walled structure consisting of a material pipe and a jacket layer nested inside and outside to form a heat medium cavity. The material pipe serves as the material conveying and distribution channel for the fiber solution from the booster pump to the spinning machine; the jacket layer cooperates with the material pipe to form a heat medium cavity; the heat medium cavity stores the heat medium, providing a constant temperature environment for the conveying and distribution of the fiber solution in this utility model. This helps maintain the relative stability of the viscosity and other properties of the fiber solution during the conveying and distribution process, thus providing a prerequisite for achieving uniform spinning in each spinning assembly. The material pipe… The material pipeline is a material conveying and distribution channel formed by sequentially connecting a material inlet flange, an inlet flow channel, a distribution joint, several outlet flow channels connected in parallel with the outlet end of the distribution joint in a circumferentially distributed manner, and material outlet flanges connected to the outlet ends of each outlet flow channel. (The material pipeline is the material conveying and distribution channel for fiber dope from the booster pump to the spinning machine. First, the fiber dope extruded under high pressure from the booster pump enters the inlet flow channel through the material inlet flange for buffering and transition. Due to the relatively short inlet flow channel, coupled with the constant temperature environment provided by the heat medium in the heat medium circulation loop, the fiber dope is conveyed through the inlet flow channel...) During the process, the viscosity and other properties of the fiber solution can be kept relatively stable. Then, the fiber solution at the outlet end of the inlet channel enters the distribution joint for uniform distribution, allowing the fiber solution to evenly enter each branch channel consisting of an outlet channel and a material outlet flange, and then enters the spinning assembly corresponding to each branch channel. This provides a prerequisite for uniform spinning in each spinning assembly. Heat transfer connection holes (for quick connection to the inlet pipe of the external hot water circulation system) are provided on the jacket layer near the material inlet flange and each material outlet flange. Instrument mounting holes (for instrument detection) are radially provided on the circumferential surface of the material inlet flange. The pressure and temperature instruments are quickly installed for real-time monitoring to ensure the normal pressure and temperature characteristics of the fiber solution. A process plane is milled on both the upper and lower parts of the circumferential surface near the inlet end of the distribution joint. A burst pressure relief port connected to the inner cavity is opened from top to bottom on the upper process plane (when the material pressure or temperature is too high, the burst pressure relief port connected to the external pressure relief pipe will burst to release pressure, providing safety protection). A material sampling port connected to the inner cavity is opened from bottom to top on the lower process plane (for periodic sampling to test the viscosity or other characteristics of the fiber solution, facilitating better process optimization and adjustment).

[0007] The jacket layer described in this utility model is an integral jacket layer formed by sequentially connecting jacket I (which wraps around the back of the material inlet flange and the periphery of the inlet flow channel), jacket II (which wraps around the periphery of the inlet flow channel), and several jackets III (which wrap around the back of each outlet flow channel and the back of the corresponding material outlet flange). Guide ribs I are provided on the inner surface of the shell wall of jacket I (to guide the flow of the heat medium, eliminate temperature dead zones, enhance heat transfer, and achieve efficient and uniform temperature control; at the same time, they can also enhance the structural rigidity of the heat medium cavity). Guide ribs II are provided on the inner surface of the shell wall of jacket III (to guide the flow of the heat medium, eliminate temperature dead zones, enhance heat transfer, and achieve efficient and uniform temperature control; at the same time, they can also enhance the structural rigidity of the heat medium cavity).

[0008] In this invention, the heat medium connection hole near the material inlet flange is connected to the inlet pipe of the external hot water circulation system, and the heat medium connection hole near each material outlet flange is connected to the return pipe of the external hot water circulation system (after the inlet and outlet ends are connected to the external hot water circulation system, the heat medium can circulate smoothly in the heat medium circulation loop composed of the heat medium jacket and the external hot water circulation system, providing a constant temperature environment for the transportation and distribution of fiber raw liquid in this invention).

[0009] The number of outlet channels and material outlet flanges in this invention is designed to match the production capacity of the spinning machine (thus, this invention can be adapted to spinning machines with different production capacities, and has the advantages of strong versatility and wide applicability).

[0010] In this utility model, fastener connection holes are machined in the thickness direction of the material inlet flange and in the thickness direction of each material outlet flange (for installing fasteners to achieve quick connection between this utility model and the booster pump or spinning machine branch pipeline); fastener connection holes are machined in the vertical direction of the process plane (for installing fasteners to achieve quick connection and fixation of external pressure relief pipelines or sampling instruments).

[0011] The design principle of this utility model is as follows: This invention features a double-walled structure consisting of a material pipeline and a jacket layer nested inside and outside to form a heat medium cavity. The jacket layer and the material pipeline work together to form a heat medium cavity, which is connected to an external hot water circulation system to form a heat medium circulation loop. The heat medium circulates smoothly in the heat medium circulation loop, providing a constant temperature environment for the delivery and distribution of the fiber solution in this invention. The material pipeline is the material conveying and distribution channel for the fiber solution from the booster pump to the spinning machine. First, the fiber solution extruded under high pressure from the booster pump enters the inlet channel through the material inlet flange for buffering and transition. Due to the relatively short inlet channel and the constant temperature environment provided by the heat medium in the heat medium circulation loop, the fiber solution can maintain relatively stable viscosity and other properties during the conveying process through the inlet channel. Next, the fiber solution at the outlet end of the inlet channel enters the distribution joint for uniform distribution, so that the fiber solution enters each branch channel composed of the outlet channel and the material outlet flange evenly, and then enters the spinning machine pipeline branch connected to each branch channel. This provides a prerequisite guarantee for uniform spinning of each spinning assembly. Meanwhile, pressure and temperature instruments can be used to monitor the fiber solution entering this invention in real time, ensuring its normal pressure and temperature characteristics. When the material pressure or temperature is too high, the burst pressure relief port connected to the external pressure relief pipe will burst to release pressure, providing safety protection. A material sampling port allows for periodic sampling to test the viscosity or other properties of the fiber solution, facilitating better process optimization and adjustment. Furthermore, this invention is compatible with spinning machines of different capacities—the number of outlet channels and material outlet flanges described in this invention is designed to match the spinning machine's capacity. This invention also boasts advantages of strong versatility and wide applicability.

[0012] The beneficial effects of this utility model are as follows: This invention enables the fiber solution extruded by the booster pump to be safely and smoothly transported to the spinning machine while maintaining relatively stable properties such as viscosity. This provides a prerequisite for achieving uniform spinning in each spinning assembly. At the same time, it can be adapted to spinning machines with different production capacities and has the advantages of strong versatility and wide applicability. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 , Figure 2As shown, this utility model discloses a multifunctional distribution device suitable for conveying viscous fluids, consisting of a double-walled structure with a material pipeline A and a jacket layer B nested inside and outside to form a heat medium cavity C. (The material pipeline A is the material conveying and distribution channel for the fiber solution from the booster pump to the spinning machine; the jacket layer B is used to cooperate with the material pipeline A to form a heat medium cavity C; the heat medium cavity C is used to store the heat medium, providing a constant temperature environment for the conveying and distribution of the fiber solution in this utility model. This helps to maintain the relative stability of the viscosity and other properties of the fiber solution during the conveying and distribution process, thus providing a prerequisite guarantee for uniform spinning of each spinning assembly). The material pipeline... Material pipe A is a material conveying and distribution channel formed by connecting the following components in sequence along the axial direction: material inlet flange 1, inlet channel 2, distribution connector 3, several outlet channels 4 connected in a circumferentially distributed parallel manner to the outlet end of the distribution connector, and material outlet flange 5, which is connected to the outlet end of each outlet channel. (Material pipe A is the material conveying and distribution channel for fiber dope from the booster pump to the spinning machine. First, the fiber dope extruded under high pressure from the booster pump enters the inlet channel 2 through material inlet flange 1 for buffering and transition. Because inlet channel 2 is relatively short, and due to the constant temperature environment provided by the heat medium in the heat medium circulation loop, the fiber dope is conveyed through inlet channel 2.) Basically, it can maintain the viscosity and other properties of the fiber solution relatively stable; then, the fiber solution at the outlet end of the inlet channel 2 enters the distribution joint 3 for uniform distribution, so that the fiber solution enters each branch channel composed of the outlet channel 4 and the material outlet flange 5 evenly, and then enters the spinning machine pipeline branch connected to each branch channel. This provides a prerequisite guarantee for uniform spinning of each spinning assembly; heat medium connection holes 11 (for quick connection to the water inlet pipe of the external hot water circulation system) are opened on the jacket layer B near the material inlet flange and each material outlet flange, and instrument detection mounting holes 12 (for quick connection to the external hot water circulation system) are opened radially on the circumferential surface of the material inlet flange 1. Quickly install pressure and temperature instruments and detection elements for real-time monitoring to ensure the normal characteristics of the fiber solution, such as pressure and temperature. In the distribution joint 3, a process plane 3-1 is milled on the upper and lower parts of the circumferential surface near the inlet end. On the upper process plane, a burst pressure relief port 3-2 connected to the inner cavity is opened from top to bottom (when the material pressure or temperature is too high, the burst pressure relief port 3-2 connected to the external pressure relief pipe will burst and relieve pressure, playing a safety protection role). On the lower process plane, a material sampling port 3-3 connected to the inner cavity is opened from bottom to top (used for timed sampling to detect the viscosity or other characteristics of the fiber solution, so as to better optimize and adjust the process).

[0017] The jacket layer B described in this utility model is an integral jacket layer formed by sequentially connecting jacket I6, which is wrapped around the back of the material inlet flange and the periphery of the inlet flow channel, jacket II7, which is wrapped around the periphery of the inlet flow channel, and several jackets III8, which are wrapped around the back of each outlet flow channel and the back of the corresponding material outlet flange. Guide ribs I9 are provided on the inner surface of the shell wall of jacket I6 (to guide the flow of the heat medium, eliminate temperature dead zones, enhance heat transfer, and achieve efficient and uniform temperature control; at the same time, they can also enhance the structural rigidity of the heat medium cavity). Guide ribs II10 are provided on the inner surface of the shell wall of jacket III8 (to guide the flow of the heat medium, eliminate temperature dead zones, enhance heat transfer, and achieve efficient and uniform temperature control; at the same time, they can also enhance the structural rigidity of the heat medium cavity).

[0018] In this utility model, the heat medium connection hole 11 near the material inlet flange is connected to the water inlet pipe of the external hot water circulation system, and the heat medium connection hole 11 near each material outlet flange is connected to the return water pipe of the external hot water circulation system. (After the inlet and outlet ends are connected to the external hot water circulation system, the heat medium can circulate smoothly in the heat medium circulation loop composed of the heat medium jacket C and the external hot water circulation system, providing a constant temperature environment for the transportation and distribution of fiber raw liquid in this utility model.)

[0019] The number of outlet flow channel 4 and material outlet flange 5 in this invention is designed to match the production capacity of the spinning machine (in this way, this invention can be adapted to spinning machines with different production capacities, and has the advantages of strong versatility and wide applicability).

[0020] In this utility model, fastener connection holes are machined in the thickness direction of the material inlet flange 1 and in the thickness direction of each material outlet flange 5 (for installing fasteners to achieve quick connection between this utility model and the booster pump or spinning machine branch pipeline); fastener connection holes are machined in the vertical direction of the process plane 3-1 (for installing fasteners to achieve quick connection and fixation of external pressure relief pipelines or sampling instruments).

[0021] The specific usage of this utility model is as follows: First, install this utility model between the booster pump and the spinning machine—that is, align the material inlet flange 1 of this utility model with the outlet flange of the booster pump and then insert fasteners to connect and tighten it. Then, align the material outlet flange 5 with the inlet flange in the branch pipeline of each spinning machine and then insert fasteners to connect and tighten it.

[0022] Next, the heat medium connection hole 11 near the material inlet flange end described in this utility model is connected to the water inlet pipe of the external hot water circulation system, and the heat medium connection hole 11 near each material outlet flange end is connected to the water return pipe of the external hot water circulation system.

[0023] Then, install the pressure and temperature instrument detection element in the instrument detection mounting hole 12 on the circumferential surface of the material inlet flange 1; connect the external pressure relief pipe to the rupture pressure relief port 3-2; quickly connect the sampling instrument to the material sampling port 3-3 and fix it.

[0024] Finally, all pipeline valves are opened to begin normal operation (i.e., the control valve at the outlet of the booster pump is opened, the control valve in the heat medium circulation loop is opened, the switches of the pressure and temperature instrument detection elements are opened, and the switch of the sampling instrument is opened at regular intervals). First, the fiber solution extruded from the booster pump under high pressure enters the inlet channel 2 through the material inlet flange 1 for buffering and transition. Due to the relatively short inlet channel 2, coupled with the constant temperature environment provided by the heat medium in the heat medium circulation loop, the fiber solution can basically maintain relatively stable viscosity and other properties during the conveying process through the inlet channel 2. Then, the fiber solution at the outlet of the inlet channel 2 enters the distribution joint 3 for uniform distribution, so that the fiber solution enters each branch channel composed of the outlet channel 4 and the material outlet flange 5 evenly, and then enters the spinning machine pipeline branch connected to each branch channel. This provides a prerequisite guarantee for the uniform spinning of each spinning assembly. Meanwhile, pressure and temperature instruments can be used to monitor the fiber solution entering this invention in real time, ensuring the normal characteristics of the fiber solution such as pressure and temperature. When the material pressure or temperature is too high, the burst pressure relief port 3-2 connected to the external pressure relief pipe will burst to release pressure, playing a safety protection role. Sampling instruments are used to take samples at regular intervals to detect the viscosity or other characteristics of the fiber solution, so as to better optimize and adjust the process.

[0025] By operating this invention as described above, the fiber solution extruded by the booster pump can be safely and smoothly delivered to the spinning machine while maintaining relatively stable viscosity and other properties. This provides a prerequisite guarantee for uniform spinning of each spinning assembly. Furthermore, this invention is adaptable to spinning machines with different capacities—that is, the number of outlet channels 4 and material outlet flanges 5 described in this invention is designed to match the capacity of the spinning machine. This invention also has the advantages of strong versatility and wide applicability.
