[0028] The following is a detailed description of the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 The implementation scenario of the raw liquid feeding device for spinning experiments provided by the present application is illustrated. Figure 1 In the present invention, the raw solution feeding device 1000 for spinning experiments is used for the research and development of spandex products. After the preparation of the polymerization raw solution is completed in the small polymerization reactor 2000, the polymerization raw solution is transferred to the raw solution feeding device 1000 for the spandex spinning experiments. After the transfer of the polymerization raw solution is completed, the raw solution feeding device 1000 for the spandex spinning experiments is connected to the spinning assembly 3000 of the production line to start spinning.

[0030] like Figure 2 and Figure 3 An embodiment of a raw liquid feeding device for spinning experiments of the present application is illustrated, and the raw liquid feeding device for spinning experiments comprises: a cylinder 1, an upper cover 2 connected to the top of the cylinder 1, and a bottom cover 3 connected to the bottom of the cylinder 1, the upper cover 2 and the cylinder 1 are connected via a flange, and a sealing gasket is arranged between the flanges; the upper cover 2 is provided with a through exhaust mechanism 21 and a feeding mechanism 22, and the feeding mechanism 22 is inclined to the upper cover 2; a discharge mechanism 31 is arranged at the bottom of the bottom cover.

[0031] In one embodiment provided in the present application, the cylinder 1 is used as the main body of the device to contain the spinning solution. The upper cover 2 is connected to the top of the cylinder 1, connected by a flange and provided with a sealing gasket to ensure good sealing performance. An exhaust mechanism 21 is provided on the upper cover 2, and the exhaust mechanism 21 is used to discharge the gas in the cylinder stock solution during the experiment. The feeding mechanism 22 is tilted to facilitate the feeding of the spinning solution and reduce the upward mixing of the stock solution in the cylinder. The bottom cover 3 is connected to the bottom of the cylinder 1, and the cylinder 1 and the bottom cover 3 are welded as a whole. A discharging mechanism 31 is provided on the bottom cover 3, and the discharging mechanism is used to connect the spinning assembly of the production line.

[0032] During the specific use of the raw liquid feeding device for spinning experiments, after the small-scale polymerization reactor completes the preparation of the polymerization raw liquid, the polymerization raw liquid is transferred to the raw liquid feeding device for spandex spinning experiments. Before transferring the raw liquid, the discharge mechanism 31 below the bottom cover is connected to the spinning material tube, and then the polymerization raw liquid is transferred. After the transfer is completed, the upper cover is connected to the cylinder body by bolts, the bolts are tightened, the exhaust mechanism 21 on the top of the upper cover is opened, and the discharge pipe of the metering pump on the production line is connected to the quick plug 222 of the feeding mechanism 22 of the device, and then the exhaust mechanism 21 on the top of the upper cover is closed. After the spinning material tube connected to the discharge mechanism 31 below the bottom cover 3 has material discharged, the spinning material tube is connected to the spinning assembly of the production line to realize the spinning of the small-scale test polymerization raw liquid.

[0033] The spinning experiment raw liquid feeding device provided in this embodiment solves the problem that there is no small-scale experimental device for spandex spinning on the market, and there is leakage when using a cylindrical filter without a filter element as an experimental spinning feeding device for experiments. The device has a simple structure and is easy to process, providing convenience for the small-scale development of spandex products.

[0034] like Figure 2-4In the optional embodiment of the present application shown in the figure, the upper cover 2 and / or the bottom cover 3 are hemispherical covers or conical covers. The upper cover 2 is in the shape of a hemispherical cover or a conical cover, which can better cooperate with the top of the barrel 1, enhance the overall sealing performance, and further reduce the risk of leakage. The hemispherical or conical design can more effectively guide the flow of gas, so that the gas is concentrated at the highest point, which is conducive to the exhaust mechanism 21 being smoother when exhausting and reducing the accumulation of gas in the device. The upper cover 2 is a hemispherical or conical cover with a smooth surface, which is not easy to accumulate residues, and is convenient for the experimenter to clean and maintain after the experiment. The bottom cover 3 is a hemispherical cover or a conical cover, which is conducive to the spinning solution in the raw solution feeding device for the spinning experiment to be completely discharged from the raw solution feeding device, and prevents the spinning solution from accumulating in the raw solution feeding device.

[0035] like Figure 1-3 In the illustrated optional embodiment of the present application, the exhaust mechanism 21 includes a conical exhaust pipe 211 connected to the upper cover, an exhaust discharge short pipe 212 connected above the conical exhaust pipe 211, and an exhaust valve 213 arranged on the exhaust discharge short pipe 212. The conical design of the conical exhaust pipe 211 is conducive to the accumulation of gas into the conical cavity, which is conducive to the smooth flow of gas in the exhaust mechanism 21 and reduces the air flow resistance. The conical exhaust pipe 211 is connected to the upper cover and is used to guide the gas inside the raw liquid feeding device. The exhaust discharge short pipe 212 is connected above the conical exhaust pipe 211, which plays the role of extending the exhaust pipe and facilitating the installation of the exhaust valve. The length of the exhaust discharge short pipe 212 can be adjusted according to actual needs. The exhaust valve 213 is installed on the exhaust discharge short pipe 212 to control the discharge of gas.

[0036] like Figure 2-4 In the preferred embodiment of the present application shown in the figure, the angle between the axis of the feeding mechanism and the horizontal direction is 20°. Through this arrangement, when the spinning solution enters the spinning experiment solution feeding device through the feeding mechanism, due to the inclination of the feeding mechanism, the solution will enter the inside of the spinning experiment solution feeding device along the inner wall, reducing the upward mixing of the solution in the barrel, and also helping to reduce the bubbles generated during the feeding process. Preferably, the angle is 20°, and those skilled in the art can also adjust it according to specific experimental requirements and equipment conditions. In practical applications, other factors such as feeding speed, barrel size, etc. need to be considered to ensure the best feeding process.

[0037] like Figure 2-4In the preferred embodiment of the present application shown in FIG. 2 , the feeding mechanism 22 further includes a tapered feeding tube 221 and a feeding port 222 connected to the top of the tapered feeding tube 221, and the feeding port 222 is a quick plug. The tapered feeding tube 221 is the main part of the feeding mechanism, and its design is conducive to the smooth flow of the stock solution. The tapered structure can guide the stock solution to flow downward or along the inner wall. The feeding port 222 is connected to the top of the tapered feeding tube 221, and is the entrance for the experimenter to add the spinning stock solution. The feeding port 222 is designed as a quick plug, which is convenient for the experimenter to quickly connect and disconnect the feeding tube, which is convenient for experimental operation.

[0038] like Figure 4 In the optional embodiment of the present application, the feeding mechanism 22 further includes a baffle 223 extending into the cavity of the upper cover 2, and the baffle 223 can prevent the spinning solution from overflowing. The baffle 223 extends from the conical feeding tube 221 into its cavity, and the function of the baffle 223 is to reduce the overflow of the spinning solution during the feeding process.

[0039] like Figure 1 , 3 In the optional embodiment of the illustrated application, the discharge mechanism 31 includes: a discharge short tube 311 connected to the bottom cover 3, an inverted conical discharge tube 312 installed at the bottom of the discharge short tube 311, and a discharge port 313 connected to the inverted conical discharge tube 312, and the discharge port 313 is a quick plug. The discharge short tube 311 is connected to the bottom cover as the starting part of the discharge mechanism. Its length and diameter are usually designed according to the experimental requirements and equipment specifications to ensure a tight connection with the bottom cover and a smooth flow of the stock solution. The inverted conical discharge tube 312 is installed at the bottom of the discharge short tube 311, and its design helps to concentrate and discharge the stock solution smoothly. The inverted conical structure can gradually reduce the outlet area, thereby increasing the flow rate and reducing the residue. The discharge port 313 is connected to the bottom of the inverted conical discharge tube 312, which is the final discharge position of the stock solution. The discharge port 313 is designed as a quick plug and can be directly plugged into the spinning material tube of the production line, which is convenient for the experimenter to quickly connect and disconnect the discharge tube, and is convenient for experimental operation.

[0040] In an optional embodiment of the present application, the discharge short tube 311 is connected to the inverted cone discharge tube 312 via a flange, and a sealing gasket is installed between the flanges. When the discharge short tube 311 is connected to the inverted cone discharge tube 312 via a flange, and a sealing gasket is installed between the flanges, such a design ensures the sealing and stability of the connection, which is crucial to preventing liquid leakage and improving system safety.

[0041] like Figure 5 In the optional embodiment of the present application, the upper cover is further provided with a gas intake structure 23. Nitrogen is filled into the gas intake structure 23 for pressure maintenance.
