Description

Technical Field

[0001] This utility model relates to the field of carbon fiber manufacturing technology, and in particular to a wet-process carbon fiber mixing cylinder mechanism. Background Technology

[0002] Wet spinning is one of the important processes for preparing carbon fibers (carbon fibers). It involves dissolving the precursor polymer in a solvent to form a spinning solution, which is then extruded through a spinneret and enters a coagulation bath. A double diffusion process occurs between the solvent and the non-solvent (coagulation bath), causing the polymer to precipitate and solidify to form fibers. Subsequent processes such as thermal oxidation stabilization, carbonization, and graphitization are then used to convert it into carbon fibers. A mixing cylinder is typically used to dissolve the precursor polymer in the solvent.

[0003] In cold weather, the factory environment is quite cold, and large temperature control machines such as central air conditioning are usually used to raise the overall temperature in the factory. However, the mixing unit heats up slowly, and it requires a long preheating time when starting the machine every morning, which reduces the efficiency of the mixing drum in producing carbon fiber. Utility Model Content

[0004] The purpose of this invention is to solve the problem that mixing cylinders in the prior art require long preheating times in cold weather, and to propose a wet-forming carbon fiber mixing cylinder mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wet-process carbon fiber mixing cylinder mechanism includes a mixing cylinder body, a stirring shaft rotatably connected inside the mixing cylinder body, an infrared temperature sensor installed in the middle of the mixing cylinder body, a display screen electrically connected to the infrared temperature sensor connected to the upper end of the mixing cylinder body, and an adjustment mechanism for changing the temperature inside the mixing cylinder body installed on the surface of the mixing cylinder body.

[0007] The regulating mechanism includes an S-shaped metal tube wrapped around the surface of the mixing drum body. The two ends of the S-shaped metal tube are respectively connected to an inlet pipe and a drain pipe. The inlet pipe is located above the drain pipe. One end of the inlet pipe is connected to a booster pump. A hot water chamber and a cold water chamber are connected to the outside of the mixing drum body. A heating rod is installed in the hot water chamber. A first regulating valve is provided between the hot water chamber and the cold water chamber. The first regulating valve is connected to the input end of the booster pump. One end of the drain pipe is connected to a second regulating valve.

[0008] Preferably, both the first regulating valve and the second regulating valve have a first ball and a second ball rotatably connected inside them.

[0009] Preferably, both the first sphere and the second sphere are provided with L-shaped through grooves, and both the surface of the first sphere and the second sphere are connected with L-shaped rods, which are rotatably connected to the first regulating valve and the second regulating valve, respectively.

[0010] Preferably, both sides of the second regulating valve are connected to a hot water pipe and a cold water pipe, the cold water pipe being connected to the cold water chamber and the hot water pipe being connected to the hot water chamber.

[0011] Preferably, the cold water pipe is arranged in a wavy, multiple-bend pattern and is made of copper.

[0012] Preferably, multiple stirring rods are symmetrically connected to the side of the stirring shaft, and one end of each stirring rod is provided with an arc-shaped scraper, which is slidably connected to the inner wall of the mixing cylinder body.

[0013] Compared with the prior art, this utility model provides a wet-process carbon fiber mixing cylinder mechanism, which has the following beneficial effects:

[0014] 1. The wet-process carbon fiber mixing cylinder mechanism allows hot water to be introduced and maintained in the S-shaped metal tube for a period of time by rotating the first and second regulating valves. This rapidly heats the main body of the mixing cylinder and improves the utilization rate of hot water. Under the monitoring of the infrared temperature sensor and the display screen, the temperature of the mixture in the main body of the mixing cylinder is raised to a certain level, thereby increasing the mixing and dissolution rate.

[0015] 2. The wet-formed carbon fiber mixing cylinder mechanism replaces the hot water in the S-shaped metal pipe with flowing cold water by rotating the first regulating valve and the second regulating valve. This allows for continuous absorption of heat from the mixing cylinder body. The cold water in the S-shaped metal pipe dissipates heat in the copper cold water pipe arranged in a wavy, multi-bend pattern, and then returns to the cold water chamber to achieve cold water circulation, which facilitates control of temperature changes within the mixing cylinder body.

[0024] Reference Figure 1-5 A wet-process carbon fiber mixing cylinder mechanism includes a mixing cylinder body 1. A stirring shaft 2 installed inside the mixing cylinder body 1 can dissolve the precursor polymer inside the mixing cylinder body 1 in a solvent to form a spinning solution. The stirring shaft 2 is rotatably connected inside the mixing cylinder body 1. An infrared temperature sensor 3 is installed in the middle of the mixing cylinder body 1. The infrared temperature sensor 3 is located above the inside of the mixing cylinder body 1 and can monitor the temperature in the middle of the mixing cylinder body 1 by receiving infrared rays and display it in real time on a display screen 4 outside the mixing cylinder body 1. This allows the worker to make appropriate temperature adjustments based on the temperature inside the mixing cylinder body 1 to improve the dissolution rate of the polymer in the solvent. The upper end of the mixing cylinder body 1 is connected to a display screen 4 electrically connected to the infrared temperature sensor 3. An adjustment mechanism 5 is installed on the surface of the mixing cylinder body 1 to change the temperature inside the mixing cylinder body 1. This allows for appropriate temperature adjustments based on the temperature inside the mixing cylinder to improve the mixing efficiency of the mixing cylinder body 1.

[0025] The regulating mechanism 5 includes an S-shaped metal tube 501 wrapped around the surface of the mixing drum body 1. The S-shaped metal tube 501 has good thermal conductivity and a large contact area with the mixing drum body 1. By introducing water of different temperatures into it, the temperature inside the mixing drum body 1 is changed. The two ends of the S-shaped metal tube 501 are connected to an inlet pipe 502 and a drain pipe 503, respectively. The inlet pipe 502 is connected to the high input end of the S-shaped metal tube 501, allowing water pumped from the output end of the booster pump 504 to quickly fill the S-shaped metal tube 501 and transfer heat to the mixing drum body 1. The drain pipe 503 is connected to the low output end of the S-shaped metal tube 501, allowing the hot water inside the S-shaped metal tube 501 to be quickly drained under gravity. The inlet pipe 502 is located above the drain pipe 503, and one end of the inlet pipe 502 is connected to the booster pump 504. A hot water chamber 5 is connected to the outside of the mixing drum body 1. Heating rods 507 are installed in the hot water chamber 505 and the cold water chamber 506. Both the hot water chamber 505 and the cold water chamber 506 contain low-temperature water and high-temperature water, respectively. A booster pump 504 draws water from the hot water chamber 505 and the cold water chamber 506, pressurizes it, and introduces it into the S-shaped metal pipe 501. A first regulating valve 508 is provided between the hot water chamber 505 and the cold water chamber 506. The first regulating valve 508 can connect the hot water chamber 505 to the input end of the booster pump 504 or connect the cold water chamber 506 to the input end of the booster pump 504, thereby introducing water of different temperatures into the S-shaped metal pipe 501. The first regulating valve 508 is connected to the input end of the booster pump 504. One end of the drain pipe 503 is connected to a second regulating valve 509. The second regulating valve 509 can discharge hot water and cold water separately according to the different temperatures of water introduced into the S-shaped metal pipe 501 and reuse them, which helps to improve the efficiency of hot water and cold water use.

[0026] Both the first regulating valve 508 and the second regulating valve 509 are rotatably connected to a first ball 510 and a second ball 511. The L-shaped groove 512 inside the first ball 510 can simultaneously connect the hot water chamber 505 to the booster pump 504 or the cold water chamber 506 to the booster pump 504. The L-shaped groove 512 inside the second ball 511 can simultaneously connect the hot water pipe 514 to the drain pipe 503 or the cold water pipe 515 to the drain pipe 503, or block the drain pipe 503. Both the first ball 510 and the second ball 511 are provided with L-shaped grooves 512, and L-shaped rods 513 are connected to the surfaces of both the first ball 510 and the second ball 511. The L-shaped rods 513 penetrate through to the first regulating valve 508 and the second ball 509. On the outside of the regulating valve 509, the position of the L-shaped rod 513 is the same as the position of the L-shaped through groove 512, making it convenient for workers to know the position of the L-shaped through groove 512 based on the placement of the L-shaped rod 513. Both the first regulating valve 508 and the second regulating valve 509 are designed to prevent water leakage. The first ball 510 and the second ball 511 are each provided with a positioning groove inside the first regulating valve 508 and the second regulating valve 509, facilitating a 90-degree rotation for each ball 510 and the second ball 511. The L-shaped rod 513 is rotatably connected to the first regulating valve 508 and the second regulating valve 509 respectively. Both sides of the second regulating valve 509 are connected to a hot water pipe 514 and a cold water pipe 515. The hot water pipe 514 is connected to the cold water chamber 505, and the cold water pipe 515 is arranged in a wavy, multi-bent pattern and is made of copper. When the first ball 510 in the first regulating valve 508 connects the hot water chamber 505 to the booster pump 504, hot water quickly fills the S-shaped metal pipe 501 through the inlet pipe 502. At this time, the second ball 511 in the second regulating valve 509 blocks the drain pipe 503. The hot water in the S-shaped metal pipe 501 can continuously dissipate heat to heat the mixing drum body 1, improving the efficiency of hot water use. After the hot water has been used for a period of time, the L-shaped rod 513 is rotated to connect the drain pipe 503 to the hot water pipe 514, and the S-shaped metal pipe... Hot water in 501 enters the hot water pipe 514 and the hot water chamber 505 and is reheated, improving the utilization rate of hot water. Similarly, the L-shaped through groove 512 in the first sphere 510 connects the cold water chamber 506 to the booster pump 504. At the same time, the L-shaped through groove 512 in the second sphere 511 connects the drain pipe 503 to the cold water pipe 515. At this time, cold water absorbs the temperature in the mixing cylinder body 1 from the cold water chamber 506 through the S-shaped metal pipe 501, and enters the copper wavy cold water pipe 515 with multiple bends from the drain pipe 503. It quickly dissipates heat and returns to the cold water chamber 506, realizing the effect of cold water circulation and cooling, which helps to keep the temperature in the mixing cylinder body 1 within a suitable range.

[0027] Multiple stirring rods 516 are symmetrically connected to the side of the stirring shaft 2. Each stirring rod 516 has an arc-shaped scraper 517 at one end. The arc-shaped scraper 517 is slidably connected to the inner wall of the mixing drum body 1. When hot water raises the temperature inside the mixing drum body 1, the outer mixture that is in contact with the inner wall of the mixing drum body 1 heats up first. When the stirring shaft 2 inside the mixing drum body 1 rotates and stirs, it can flip the outer mixture that is close to the inner wall of the mixing drum body 1 to the inner side close to the stirring shaft 2, so that the temperature inside the mixing drum body 1 can be quickly kept balanced.

[0028] In this invention, during carbon fiber production in cold weather, the mixing drum body 1 is activated to heat the water in the hot water chamber 505. The first regulating valve 508 and the second regulating valve 509 are rotated, allowing the hot water in the hot water chamber 505 to enter the S-shaped metal pipe 501 via the booster pump 504 and remain there for a period of time. This facilitates the transfer of heat from the hot water to the mixture within the mixing drum body 1. Furthermore, the arc-shaped scraper 517 on the surface of the stirring shaft 2 flips the pre-heated outer mixture to the inner periphery, thereby improving the heating efficiency of the mixture within the mixing drum body 1. Finally, rotating the first regulating valve 508 and the second regulating valve 509 allows the hot water in the S-shaped metal pipe 501 to enter the hot water chamber through the hot water pipe 514. 505 is reheated, and the booster pump 504 is started to introduce the hot water in the hot water chamber 505 into the S-shaped metal pipe 501 again, so as to continuously heat the mixing cylinder body 1. When the heating ends and appropriate cooling is required, the first regulating valve 508 and the second regulating valve 509 are turned so that the cold water in the cold water chamber 506 enters the S-shaped metal pipe 501 through the booster pump 504, and quickly enters the copper cold water pipe 515 from the drain pipe 503 for cooling, and then returns to the cold water chamber 506. This forms a cold water circulation system to quickly regulate the temperature of the mixing cylinder, which is beneficial to improve the production efficiency of carbon fiber when the mixing cylinder body 1 is started at the beginning of cold weather.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
