Aromatic polyamide alignment second-order polymerization device

Abstract

This utility model relates to the field of polymerization equipment technology and discloses a two-stage polymerization device for para-aramid fibers, including a barrel body. A crushing assembly is installed inside the barrel body, and a feeding assembly is provided at the bottom of the barrel body. This two-stage polymerization device for para-aramid fibers is driven by a motor to rotate a transmission rod, which in turn rotates a fixed rod. The transmission rod and fixed rod in this assembly serve to transmit power. When the fixed rod rotates, it causes the first connecting rod and the second connecting rod to rotate synchronously, thereby causing the first crushing roller and the second crushing roller to rotate. This achieves a secondary crushing effect on the raw material, making the raw material more finely crushed. Then, the rotating stirring rod mixes the raw material. This assembly can achieve automatic crushing before stirring, eliminating the need for separate crushing devices and improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of polymerization apparatus technology, specifically to a para-aramid second-stage polymerization apparatus. Background Technology

[0002] Para-aramid, also known as poly(p-phenylene terephthalamide) fiber, is a high-performance synthetic fiber with high surface hardness, excellent abrasion resistance, and high tear strength. It can withstand repeated friction and stretching without being easily damaged and is widely used in the manufacture of protective equipment such as bulletproof vests, bulletproof helmets, fire suits, and heat-insulating clothing, effectively protecting personnel safety and reducing accident casualties.

[0003] The para-aramid two-stage polymerization unit is a key piece of equipment for the production of para-aramid. The prepolymerized material enters the polymerization reactor, and the stirring drive motor drives the stirring and crushing mechanism to stir and crush the material, further promoting the reaction and making the material evenly mixed. The temperature control device on the outer wall can precisely control the reaction temperature to meet the requirements of the polymerization reaction and ensure the production of high-quality para-aramid resin. After the reaction is completed, the product is discharged from the rotary discharge valve at the bottom of the storage silo.

[0004] The prior art patent document CN218689456U provides a polymerization reaction device. In use, the sealing seat is rotated upward to adjust the height of the conical seat inside the barrel. The conical seat is moved upward by the thrust generated by the support mechanism. After the vertical movement, the stirring rod loses its support force. The tilt angle is changed by the reset mechanism to change the stirring direction and position of the material inside the conical groove.

[0005] Although the aforementioned prior art allows the polymerization reactor to be moved out of the barrel via a conical seat, facilitating subsequent cleaning and reuse, and the conical groove inside the conical seat works in conjunction with the stirring rod to reduce the working space and improve stirring efficiency, the polymerization reactor in this patented technology cannot crush the raw materials during reuse. This results in larger material particles during polymerization, affecting the quality of the output. Therefore, a separate crushing process is required before using the device, which greatly reduces work efficiency. Therefore, we need a para-aramid two-stage polymerization device. Utility Model Content

[0006] The purpose of this invention is to provide a para-aramid two-stage polymerization device to solve the problem that the polymerization reaction device in the patented technology mentioned in the background art cannot crush the raw materials during use, which results in large material particles in the polymerization process, thus affecting the quality of the product. Therefore, a separate crushing operation is required before using the device, which greatly reduces the work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A para-aramid second-stage polymerization apparatus includes a barrel body, a support leg fixedly connected to the bottom of the barrel body, a material crushing assembly installed inside the barrel body, and a material feeding assembly provided at the bottom of the barrel body; The crushing assembly includes a motor, the output end of which is detachably connected to a transmission rod via a coupling, and a fixed rod is provided at the bottom of the transmission rod.

The feeding assembly includes a discharge port, a first rotating shaft is provided on one side of the discharge port, and a connecting block is rotatably connected inside the first rotating shaft. An adjusting plate is fixedly connected to one side of the connecting block. A second rotating shaft is provided on the inner wall of the discharge port, and a hydraulic cylinder is rotatably connected inside the second rotating shaft. A third rotating shaft is provided at the bottom of the hydraulic cylinder.

[0008] Preferably, a fixed screen plate is installed inside the barrel, and a feed inlet is provided at the top of the barrel.

[0009] Preferably, the motor forms a rotating structure with a transmission rod and a fixed rod, and the transmission rod is installed between the motor and the fixed rod.

[0010] Preferably, the fixing rod forms a rotating structure with the first crushing roller via a first connecting rod, and there are two first crushing rollers. The fixing rod also forms a rotating structure with the second crushing roller via a second connecting rod.

[0011] Preferably, the transmission rod forms a rotating structure with the stirring rod via a fixed rod, and there are multiple stirring rods.

[0012] Preferably, the discharge port forms a rotating structure with the connecting block via a first rotating shaft, and the first rotating shaft is installed between the discharge port and the connecting block. The first rotating shaft forms a rotating structure with the adjusting plate via the connecting block.

[0013] Preferably, the second rotating shaft forms a movable structure with the third rotating shaft via a hydraulic cylinder, and the third rotating shaft is mounted on the top of the adjusting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this device for the second-stage polymerization of para-aramid fibers, First, this utility model includes a motor, a transmission rod, a fixed rod, a first connecting rod, a first crushing roller, a second connecting rod, a second crushing roller, and a stirring rod. The motor drives the transmission rod to rotate, which in turn causes the fixed rod to rotate. The transmission rod and fixed rod in this assembly transmit power. The rotation of the fixed rod causes the first and second connecting rods to rotate synchronously, thereby causing the first and second crushing rollers to rotate. This achieves a secondary crushing effect on the raw materials, making them finer. The stirring rod then mixes the raw materials. This assembly enables automatic crushing before stirring, eliminating the need for separate crushing devices and improving work efficiency.

[0015] Secondly, this utility model is equipped with a discharge port, a first rotating shaft, a connecting block, an adjusting plate, a second rotating shaft, a hydraulic cylinder, and a third rotating shaft. When material needs to be discharged, the rotation of the first rotating shaft drives the connecting block to rotate, thereby causing the adjusting plate to rotate. This allows the discharge port to open and close, facilitating material discharge. The extension and retraction of the hydraulic cylinder pushes and pulls the third rotating shaft, and the rotation of the third rotating shaft allows for arbitrary adjustment of the opening and closing range of the adjusting plate, thus adjusting the discharge volume. This component facilitates the automatic discharge of aligned aramid masterbatch from the barrel and controls the discharge volume, improving work efficiency. Attached Figure Description

[0023] Specifically, the motor 301 forms a rotating structure with the fixed rod 303 via the transmission rod 302, and the transmission rod 302 is installed between the motor 301 and the fixed rod 303.

[0024] Through the above technical solution, the transmission rod 302 can be driven to rotate by the motor 301, thereby causing the fixed rod 303 to rotate. The transmission rod 302 and the fixed rod 303 are arranged in this component to transmit power.

[0025] Specifically, the fixed rod 303 forms a rotating structure with the first crushing roller 305 through the first connecting rod 304, and there are two first crushing rollers 305. The fixed rod 303 forms a rotating structure with the second crushing roller 307 through the second connecting rod 306.

[0026] Through the above technical solution, when the fixed rod 303 rotates, the first connecting rod 304 and the second connecting rod 306 can rotate synchronously, thereby enabling the first crushing roller 305 and the second crushing roller 307 to rotate, thus achieving a secondary crushing effect on the raw materials and making the raw materials more finely crushed.

[0033] Working Principle: When using this para-aramid two-stage polymerization device, firstly, the motor 301 is manually started. The motor 301 drives the transmission rod 302 to rotate, which in turn rotates the fixed rod 303. The rotation of the fixed rod 303 causes the first connecting rod 304 and the second connecting rod 306 to rotate synchronously, thereby causing the first crushing roller 305 and the second crushing roller 307 to rotate. Then, the raw material is fed through the feed inlet 5. The rotation of the first crushing roller 305 and the second crushing roller 307 performs secondary crushing on the raw material, which is then further crushed by the rotation of the stirring rod 308. The raw materials are mixed by stirring, and the mixed and polymerized raw materials are discharged through the discharge port 601. First, the extension and retraction of the hydraulic cylinder 606 drives the third rotating shaft 607 to move. The rotation of the third rotating shaft 607 causes the adjusting plate 604 to rotate.
