Description

Technical Field

[0001] This utility model relates to the field of degassing technology of raw solution, specifically a degassing device for para-aramid spinning raw solution. Background Technology

[0002] Para-aramid, also known as poly(p-phenylene terephthalamide), is a high-performance fiber used to make personal protective equipment such as high-temperature protective clothing and cut-resistant gloves. It can also be processed into specialty paper, high-strength webbing, and pipelines. It is also used in various sports equipment such as golf clubs, tennis rackets, and sleds. In the field of electronic communications, it can be processed into insulated circuit boards for insulation protection and reinforcement of wires and cables, improving the strength and tensile properties of cables and ensuring the stability of signal transmission.

[0003] The degassing device for para-aramid spinning solution is used to remove air bubbles from the para-aramid spinning solution. Because air or other gases may be mixed into the para-aramid spinning solution during the preparation process, forming air bubbles, if these air bubbles are not removed in time, they will cause problems such as fiber breakage and surface defects during the spinning process, affecting the quality and performance of the fiber.

[0004] The prior art patent document CN215251348U provides a degassing device for para-aramid spinning solution. This degassing device, by setting up an aramid degassing kettle, can perform special degassing treatment on the mixed spinning solution, thereby improving production efficiency. It is also equipped with a concentrated sulfuric acid pipeline to facilitate cleaning of the aramid degassing kettle. Furthermore, the manufacturing process is simple and the operation is convenient.

[0005] Although the aforementioned prior art deaerator can deaerator the mixed spinning solution through the aramid deaerator and can clean the inside of the aramid deaerator through a specially designed pipe, making the operation very simple, the deaerator in this patented technology uses a scraper to scrape the inside of the deaerator when cleaning it. This can easily damage the inner wall of the deaerator, affecting the deaerator's performance, reducing the device's lifespan, and lowering its practicality. Therefore, we need a para-aramid spinning solution deaerator. Utility Model Content

The stirring assembly 3 includes a motor 301. The output end of the motor 301 is detachably connected to a transmission rod 302 via a coupling. A first pulley 303 is provided on the outer wall of the transmission rod 302. A belt 304 is rotatably connected to the outer wall of the first pulley 303. A second pulley 305 is provided on the inner wall of the belt 304. A connecting rod 306 is installed at the bottom of the second pulley 305. A fixing rod 307 is fixedly connected to the outer surface of the connecting rod 306. A cleaning brush 308 is provided at one end of the fixing rod 307. A stirring roller 309 is installed on the outer surface of the connecting rod 306. The drainage assembly 6 includes a drainage pipe 601, a first rotating shaft 602 is provided on one side of the drainage pipe 601, and a connecting block 603 is rotatably connected inside the first rotating shaft 602. An adjusting plate 604 is fixedly connected to one side of the connecting block 603.

A third rotating shaft 607 is provided at the bottom of the hydraulic cylinder 606.

[0020] With the above technical solution, starting the motor 301 drives the transmission rod 302 to rotate, causing the first pulley 303 to rotate. The belt 304 then drives the second pulley 305 to rotate. The arrangement of the first pulley 303, belt 304, and second pulley 305 transmits power, enabling the connecting rod 306 to rotate. The rotation of the connecting rod 306 drives the fixed rod 307 to rotate, thereby causing the cleaning brush 308 to rotate. This effectively cleans the raw liquid adhering to the inner wall of the tank 1, reducing the problem of raw liquid adhesion. Simultaneously, the rotation of the connecting rod 306 also drives the stirring roller 309 to rotate, agitating the raw liquid inside the tank 1 and ensuring thorough defoaming. This component significantly improves production efficiency and reduces the problem of raw liquid adhesion.

[0021] Specifically, the top of the tank body 1 is provided with a liquid inlet 4.

[0022] Using the above technical solution, the feeding process can be completed by manually pouring the prepared raw liquid into the tank 1 through the inlet 4.

[0023] Specifically, the motor 301 forms a rotating structure with the first pulley 303 through the transmission rod 302, and the shape and size of the outer wall of the transmission rod 302 match the shape and size of the inner wall of the first pulley 303. The first pulley 303 forms a rotating structure with the second pulley 305 through the belt 304.

[0024] Through the above technical solution, the first pulley 303, the belt 304, and the second pulley 305 form a pulley group. The motor 301 drives the transmission rod 302 to rotate, and the rotation of the transmission rod 302 drives the pulley group to rotate, thus playing the role of transmitting power in this component.

[0025] Specifically, the second pulley 305 forms a rotating structure with the fixed rod 307 via the connecting rod 306, and there are multiple fixed rods 307. The connecting rod 306 forms a fixed structure with the cleaning brush 308 via the fixed rods 307.

[0026] Through the above technical solution, the rotation of the second pulley 305 can drive the connecting rod 306 to rotate, and through the connection of the fixed rod 307, the cleaning brush 308 can also rotate synchronously. The rotation of the cleaning brush 308 can clean the inner wall of the barrel 1, reducing the problem of the original liquid adhering to the inner wall of the barrel 1.

[0027] Specifically, the second pulley 305 forms a rotating structure with the stirring roller 309 via the connecting rod 306, and there are multiple stirring rollers 309.

[0028] Through the above technical solution, while the connecting rod 306 rotates, it can drive the stirring roller 309 to rotate. The simultaneous rotation of multiple stirring rollers 309 can play a role in stirring and mixing the original liquid inside the tank 1.

[0029] Specifically, the liquid outlet pipe 601 forms a rotating structure with the connecting block 603 via the first rotating shaft 602, and the first rotating shaft 602 is installed between the liquid outlet pipe 601 and the connecting block 603. The first rotating shaft 602 forms a rotating structure with the adjusting plate 604 via the connecting block 603.

[0030] Through the above technical solution, the rotation of the first rotating shaft 602 can drive the connecting block 603 to rotate, and when the connecting block 603 rotates, the adjusting plate 604 can rotate, thereby opening and closing the liquid outlet pipe 601, which facilitates the discharge of the original liquid inside the tank 1.

[0031] Specifically, the second rotating shaft 605 forms a moving structure with the third rotating shaft 607 via the hydraulic cylinder 606, and the third rotating shaft 607 is mounted on the top of the adjusting plate 604.

[0032] Through the above technical solution, the extension and retraction of the hydraulic cylinder 606 can drive the third rotating shaft 607 to move, and the rotation of the second rotating shaft 605 and the third rotating shaft 607 can make the adjusting plate 604 rotate synchronously, thereby controlling the opening and closing size of the adjusting plate 604.

[0033] Working principle: When using this para-aramid spinning solution degassing device, firstly, the solution is manually poured into the tank 1 through the inlet 4. Then, the motor 301 is started, which drives the transmission rod 302 to rotate. The rotation of the transmission rod 302 drives the first pulley 303 to rotate, which in turn drives the second pulley 305 to rotate via the belt 304. This, in turn, drives the connecting rod 306 to rotate. The rotation of the connecting rod 306 drives the fixed rod 307 and the cleaning brush 308 to rotate, cleaning the inner wall of the tank 1. Simultaneously, it also drives the stirring roller 309 to rotate, thus cleaning the inside of the tank 1. The original liquid is stirred and defoamed. After the original liquid is defoamed, the hydraulic cylinder 606 is started. The extension and retraction of the hydraulic cylinder 606 drives the third rotating shaft 607 to move. Through the rotation connection of the third rotating shaft 607, the adjusting plate 604 is rotated. The rotation of the first rotating shaft 602 and the setting of the connecting block 603 assist the rotation of the adjusting plate 604. This enables automatic liquid discharge and allows for arbitrary control of the liquid output. This completes the entire work.
