Description

Technical Field

[0001] This utility model relates to a production apparatus for high-strength, high-modulus polyethylene fibers, and in particular to a cooling water tank for preparing high-strength, high-modulus polyethylene fiber gel filaments. Background Technology

[0002] High-strength, high-modulus polyethylene fiber has advantages such as high strength, high modulus, high orientation, light weight, impact resistance, and high dielectric properties, playing a crucial role in modern warfare, aerospace, maritime defense, and weaponry. At the same time, this fiber also has broad application prospects in automobiles, ships, ropes and nets, medical devices, and sports equipment.

[0003] The production of high-strength, high-modulus polyethylene fibers currently typically employs gel spinning technology. This involves preparing a spinning melt by mixing polyethylene with a suitable solvent, then spinning and cooling the melt to obtain gel filaments. The solvent is then removed using an extraction process, followed by heating and stretching to produce high-strength, high-modulus polyethylene fibers. The cooling process involves introducing the spinning solution extruded from the spinning box into a cooling water tank, where it solidifies into gel filaments. This keeps the ultra-high molecular weight polyethylene macromolecules in a non-entangled state along the fiber axis. During cooling, solvent continuously precipitates and is discharged from the tank with the circulating water, resulting in solvent loss and increased production costs. Furthermore, because the high temperature of the spinning melt gradually increases the temperature of the tank water as it enters, the mixing of the cooling water and the high-temperature water reduces the cooling effect on the melt, affecting the setting effect of the gel filaments. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a novel cooling water tank with a reasonable structure, easy operation, high solvent recovery rate, and good melt setting effect, thereby improving the continuous reliability of production and the product quality of gel filaments. The novel cooling water tank is characterized by mainly comprising a water storage tank, a drainage tank, an inlet tank, a drain tank, a bottom roller, guide rollers, and a filament exit roller. The inlet tank is equipped with an inlet, and a flow divider plate is provided in front of the inlet, with several flow equalization holes evenly distributed in the flow divider plate. The drainage tank is installed above the inlet tank and is equipped with a front partition plate, a water level regulating plate, an outlet, and a drain outlet. The front partition plate is located at the front end of the drainage tank, and the water level regulating plate is connected to the front partition plate. The water flow rate is adjusted by adjusting the height of the water level regulating plate. An outlet is provided in the middle of the drainage tank, and the outlet is connected to the drain outlet. A rear partition plate and a drain regulating plate are installed behind the water storage tank. The solvent flow rate is controlled by adjusting the height of the drain regulating plate, and a bottom roller is installed below it. Guide rollers are installed before and after the rear partition plate.

[0005] A filter screen is installed above the water outlet to prevent gel fiber fragments from entering the water outlet pipe and clogging the pipe.

[0006] The drainage channel has 2-8 outlets, located diagonally behind the upper component.

[0007] A regulating valve is installed at the drain outlet.

[0008] The beneficial effects of this utility model are: its structure is reasonable, it is easy to operate, it has a high solvent recovery rate and a good cooling effect, thereby improving the product quality of gel filaments.

[0009] The following detailed embodiments further illustrate the above-described content of this utility model. However, this should not be construed as limiting the scope of the above-described subject matter of this utility model to the following examples. All technologies implemented based on the above-described content of this utility model fall within the scope of this utility model. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] The high-strength, high-modulus polyethylene fiber cooling water tank of this utility model mainly includes a water storage tank 1, a drainage tank, an inlet tank, a drain tank, a bottom roller 10, a guide roller 11, and a fiber output roller 12. The inlet tank is equipped with an inlet 7 and a flow divider 9. Cooling water introduced through the inlet 7 enters the water storage tank 1 through the equalization holes in the flow divider 9, eliminating the impact force of the incoming water and ensuring a stable water flow within the tank. A drainage tank is installed above the inlet tank, and the drainage tank is equipped with a front partition plate 2, a water level regulating plate 3, an outlet 5, and a drain outlet 6. The cooling water outlet speed is adjusted by regulating the overlap between the water level regulating plate 3 on the front partition plate 2 and the overflow hole. An outlet 5 is installed in the drainage tank, and every two outlet pipes are connected to one drain outlet 6. A regulating valve is installed at each drain outlet 6 to control the water flow rate. A rear partition plate 13 and a drain regulating plate 14 are installed behind the water storage tank 1. The flow rate of the upper solvent in the water storage tank 1 is adjusted by adjusting the overlap between the drain regulating plate 14 on the rear partition plate 13 and the overflow hole. The solvent overflows into the drain tank 15, is discharged through the drain pipe 8 and collected for recycling. A bottom roller 10 is installed below the water storage tank 1. After the spinning solution enters the water tank, it passes through the bottom roller 10, forms gel filaments, and then passes through the guide roller 11 and is conveyed to the next process by the exit roller 12.
