Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of polyamide fiber processing, and particularly relates to a polyamide fiber polymerization device. BACKGROUND

[0002] Polyamide fiber, also known as nylon, is one of the earliest synthetic fibers to be industrialized in the world and is one of the most widely used varieties in the field of chemical fibers. It is widely used in textiles, engineering plastics, medical treatment and other fields due to its excellent performance. The name "polyamide fiber" is the trade name of polyamide fiber in China. The corresponding name commonly seen internationally also includes "nylon". The production process of polyamide fiber is a systematic engineering from raw material preparation to fiber product. The core can be divided into two major links of polymerization and spinning. The polyamide fiber polymerization tube is a key equipment for realizing the polymerization reaction of polyamide fiber raw materials in the production process of polyamide fiber.

[0003] At present, when the existing polymerization kettle is stirring raw materials, the motor is generally used to drive the stirring rod to rotate to stir the raw materials in the polymerization kettle. However, the stirring rod is difficult to stir the raw materials at all positions in the polymerization kettle, especially the raw materials at the edge position of the polymerization kettle, which affects the efficiency of uniform mixing of the raw materials and prolongs the polymerization reaction time. In addition, when the existing polymerization kettle is stirring raw materials, part of the raw materials will adhere to the inner wall of the polymerization kettle and be difficult to contact with the stirring rod, so that it is difficult to be stirred, which affects the fullness of the raw material mixing and wastes raw materials.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a polyamide fiber polymerization device.

[0005] The information disclosed in this BACKGROUND section is only intended to increase an understanding of the general context in which the present application can be practiced. It is not admitted that any of the information provided in this BACKGROUND section constitutes prior art. SUMMARY

[0031] As shown in the drawings, Figures 1 to 5As shown, the stirring mechanism 2 is installed in the polymerization reactor 1, and the stirring mechanism 2 comprises a main shaft 201, a pair of first rotating shafts 204, a pair of second rotating shafts 209, a pair of stirring rods 210, a pair of barrel wall scrapers 214, a control rod 217, a control arm 221 and a curved slide 223. The main shaft 201 is rotatable on the upper cover 101, and the main shaft 201 is provided in the upper cover 101 and fixed with a first cross bar 202 and a second cross bar 203. The pair of first rotating shafts 204 are rotatable at the two ends of the second cross bar 203 respectively, and the top ends of the pair of first rotating shafts 204 are fixed with first gears 205 respectively. The second gear 206 is fixed on the top wall in the upper cover 101, and the pair of first gears 205 are in meshing relationship with the second gear 206. The pair of second rotating shafts 209 are rotatable and slidable on the first cross bar 202, and the bottom ends of the first rotating shafts 204 are slidable in the second rotating shafts 209. The pair of stirring rods 210 are fixed on the pair of second rotating shafts 209 provided at one end of the first cross bar 202 respectively, and the pair of barrel wall scrapers 214 are fixed at the two ends of the first cross bar 202 respectively and abut on the inner side wall of the polymerization reactor 1. The control rod 217 is slidable in the main shaft 201, and the main shaft 201 is provided with a sliding groove 218 on the upper side of the first cross bar 202. One end of the control rod 217 provided in the sliding groove 218 is fixed with a third cross bar 219, and the two ends of the third cross bar 219 are rotatably connected between the pair of second rotating shafts 209. The control arm 221 is fixed on one end of the control rod 217 provided outside the main shaft 201, and the two ends of the control arm 221 are provided with pulleys 222 respectively. The curved slide 223 is fixed on the upper cover 101, and the pair of pulleys 222 are slidable on the curved slide 223. The driving mechanism 3 is installed on the upper cover 101 and used to drive the main shaft 201 to rotate.

[0032] In use, the raw materials of polyamide to be polymerized are firstly added into the polymerization reactor 1, and then the driving mechanism 3 drives the main shaft 201 to rotate. When the main shaft 201 rotates, the first cross bar 202 and the second cross bar 203 rotate, and the first cross bar 202 and the second cross bar 203 simultaneously drive the pair of second rotating shafts 209 and the first rotating shafts 204 to rotate. When the second cross bar 203 drives the first rotating shafts 204 to rotate, the first gears 205 at the top ends of the first rotating shafts 204 are in meshing relationship with the second gear 206, and the second gear 206 is fixed on the upper cover 101 and does not move. Therefore, when the second cross bar 203 drives the first rotating shafts 204 to rotate, the second gear 206 drives the first rotating shafts 204 to rotate automatically through the first gears 205. The first rotating shafts 204 automatically drive the second rotating shafts 209 to rotate simultaneously, and the second rotating shafts 209 drive the stirring rods 210 to rotate. When the second rotating shafts 209 drive the stirring rods 210 to rotate with the main shaft 201 as the axis, the second rotating shafts 209 also drive the stirring rods 210 to rotate with the second rotating shafts 209 as the axis, so that the stirring rods 210 can more uniformly stir the raw materials.

[0033] In addition, when the main shaft 201 rotates, the control rod 217 is arranged in the sliding groove 218 through the third cross rod 219, so that the main shaft 201 also drives the control rod 217 to rotate, the control rod 217 drives the control arm 221 to rotate, and the control arm 221 drives the pulley 222 to slide on the curved slide 223. When the pulley 222 slides on the curved slide 223, the control rod 217 is driven by the control arm 221 to move up and down, and the control rod 217 drives the pair of second rotating shafts 209 to move up and down through the third cross rod 219, and the second rotating shaft 209 drives the stirring rod 210 to move up and down. Thus, the second rotating shaft 209 drives the stirring rod 210 to rotate around the main shaft 201 and the second rotating shaft 209, and also drives the stirring rod 210 to move up and down, so that the stirring rod 210 stirs the raw materials in the upper and lower layers. Thus, the uniformity of the stirring of the stirring rod 210 is further improved. Secondly, when the main shaft 201 drives the first cross rod 202 to rotate, the main shaft 201 drives the pair of barrel wall scrapers 214 to rotate along the inner wall of the polymerization kettle 1 through the first cross rod 202, and the pair of barrel wall scrapers 214 scrape off the raw materials adhered to the inner wall of the polymerization kettle 1.

[0034] As shown in Figures 1 to 5 The top of the upper cover 101 is provided with a feeding port 108 and a plurality of auxiliary material ports 107, and a sealing cover 109 is installed on each of the feeding port 108 and the plurality of auxiliary material ports 107. The feeding port 108 is used to add main raw materials into the polymerization kettle 1, and the plurality of auxiliary material ports 107 are respectively used to add other auxiliary materials into the upper cover 101. The sidewall of the heating jacket 104 is provided with an air inlet pipe 105 and an air outlet pipe 106, and the bottom of the discharge port 102 is connected with a discharge pipe 103. The air inlet pipe 105 and the air outlet pipe 106 are used to be connected to a heating medium conveying device to convey the heating medium into the heating jacket 104, so that the heating jacket 104 heats the polymerization kettle 1. The discharge pipe 103 is used to discharge the raw materials after polymerization. The sealing cover 109 is used to seal the feeding port 108 and the auxiliary material port 107.

[0035] As shown in Figures 1 to 5As shown, the inner wall of the second rotating shaft 209 is fixed with a pair of limiting sliding strips 212, and the outer wall of the first rotating shaft 204 is drilled with a pair of limiting sliding grooves 213, and the pair of limiting sliding strips 212 respectively slide in the pair of limiting sliding grooves 213. By the pair of limiting sliding strips 212 respectively sliding in the pair of limiting sliding grooves 213, when the second rotating shaft 209 slides up and down on the first rotating shaft 204, the rotation of the first rotating shaft 204 can always drive the second rotating shaft 209 to rotate. The two ends of the second cross rod 203 are fixed with the first sliding sleeve 207, and the first rotating shaft 204 rotates on the first sliding sleeve 207. The first cross rod 202 is fixed with a pair of second sliding sleeves 208, and the second rotating shaft 209 slides and rotates on the second sliding sleeve 208. The second cross rod 203 is rotationally connected with the first rotating shaft 204 through the pair of first sliding sleeves 207 at the two ends thereof. The first cross rod 202 is slidably and rotationally arranged with the second rotating shaft 209 through the pair of second sliding sleeves 208.

[0036] As shown in the drawings, Figures 1 to 5 The bottom end of the pair of barrel wall scrapers 214 is fixed with an arc-shaped scraper 215, and a rotating head 216 is fixed between the pair of arc-shaped scrapers 215, and the inner arc angle of the arc-shaped scraper 215 corresponds to the discharge port 102. During equipment operation, the arc-shaped scraper 215 is driven to rotate by the first cross rod 202 and the barrel wall scraper 214, so that the pair of arc-shaped scrapers 215 scrape off the raw materials adhered to the bottom wall of the polymerization reactor 1. In addition, the rotating head 216 is used to assist the rotation of the arc-shaped scraper 215 to prevent deformation of the arc-shaped scraper 215 during rotation. In addition, the innermost short position of the inner arc angle of the arc-shaped scraper 215 corresponds to the discharge port 102, and when the mixed material flow is discharged through the discharge port 102, the arc-shaped scraper 215 is rotated to remove the material flow on the bottom wall of the polymerization reactor 1, and at the same time, the material is pushed to the discharge port 102, effectively improving the discharge of the material and preventing the residue of the material.

[0037] As shown in the drawings, Figures 1 to 5 The two ends of the third cross rod 219 are fixed with a third sliding sleeve 220, and the pair of second rotating shafts 209 respectively rotate on the pair of third sliding sleeves 220, and one end of the second rotating shaft 209 arranged on the third sliding sleeve 220 is fixed with a limiting head 211. The third cross rod 219 is rotationally connected with the pair of second rotating shafts 209 through the pair of third sliding sleeves 220. In addition, the limiting head 211 limits the third sliding sleeve 220 to prevent the third sliding sleeve 220 from moving out of the second rotating shaft 209.

[0038] As shown in the drawings, Figures 1 to 5As shown, the curved slide 223 is provided with a pair of high points 224 and a pair of lowest points 225, a spring 226 is installed between the control arm 221 and the top end of the main shaft 201, and the spring 226 is sleeved on the control rod 217. When the pulley 222 slides to the high point 224, the control rod 217 drives a pair of second rotating shafts 209 to move to the highest point through the third cross rod 219, and when the pulley 222 slides to the lowest point 225, the control rod 217 drives a pair of second rotating shafts 209 to move to the lowest point through the third cross rod 219. The spring 226 is used to pull the control arm 221 towards the main shaft 201, so that the control arm 221 drives the control rod 217 to slide downward.

[0039] As shown in the drawings, Figures 1 to 5 As shown, the driving mechanism 3 comprises a support 301, a first pulley 303, a second pulley 304 and a transmission belt 305. The support 301 is installed on the upper cover 101, and a transmission shaft 302 is rotatably arranged on the support 301. The first pulley 303 and the second pulley 304 are respectively fixed to the transmission shaft 302 and the end of the main shaft 201 outside the upper cover 101. The transmission belt 305 is installed on the first pulley 303 and the second pulley 304. The support 301 is fixed with a ring-shaped mounting head 307, and a motor 306 is installed on the ring-shaped mounting head 307. The motor 306 is connected with the transmission shaft 302. During equipment operation, the motor 306 drives the transmission shaft 302 to rotate, the transmission shaft 302 drives the first pulley 303 to rotate, the first pulley 303 drives the second pulley 304 to rotate through the transmission belt 305, and the second pulley 304 drives the main shaft 201 to rotate. The motor 306 is fixed on the support 301 through the ring-shaped mounting head 307.

[0040] Working principle: when the device is used, first, the polyamide raw materials and auxiliary materials needed for polymerization are added to the polymerization reactor 1 through the feeding port 108 and the auxiliary material port 107, and the gas inlet pipe 105 and the gas outlet pipe 106 are connected to the heating medium conveying device, and the heating medium is conveyed to the heating jacket 104 to heat the polymerization reactor 1. Then the motor 306 drives the transmission shaft 302 to rotate, the transmission shaft 302 drives the first pulley 303 to rotate, the first pulley 303 drives the second pulley 304 to rotate through the transmission belt 305, and the second pulley 304 drives the main shaft 201 to rotate. When the main shaft 201 rotates, the first cross rod 202 and the second cross rod 203 rotate, and the first cross rod 202 and the second cross rod 203 simultaneously drive a pair of second rotating shafts 209 and a first rotating shaft 204 to rotate.

[0041] When the second crossbar 203 drives the first rotating shaft 204 to rotate, the first gear 205 at the top end of the first rotating shaft 204 is in meshing state with the second gear 206, and the second gear 206 is fixed on the upper cover 101 and does not move, so when the second crossbar 203 drives the first rotating shaft 204 to rotate, the second gear 206 drives the first rotating shaft 204 to rotate through the first gear 205. The first rotating shaft 204 rotates at the same time to drive the second rotating shaft 209 to rotate, and the second rotating shaft 209 drives the stirring rod 210 to rotate. When the second rotating shaft 209 drives the stirring rod 210 to rotate around the main shaft 201 as the axis, the second rotating shaft 209 also drives the stirring rod 210 to rotate around the second rotating shaft 209 as the axis, so that the stirring rod 210 can more evenly stir the raw materials.

[0042] In addition, when the main shaft 201 rotates, the control rod 217 is arranged in the sliding groove 218 through the third crossbar 219, so that the main shaft 201 also drives the control rod 217 to rotate, the control rod 217 drives the control arm 221 to rotate, and the control arm 221 drives the pulley 222 to slide on the curved slide 223. When the pulley 222 slides on the curved slide 223, the control rod 217 is driven by the control arm 221 to move up and down, and the control rod 217 drives a pair of second rotating shafts 209 to move up and down through the third crossbar 219, and the second rotating shaft 209 drives the stirring rod 210 to move up and down. When the pulley 222 slides to the high point 224, the control rod 217 drives a pair of second rotating shafts 209 to move to the highest point through the third crossbar 219, and when the pulley 222 slides to the lowest point 225, the control rod 217 drives a pair of second rotating shafts 209 to move to the lowest point. When the pulley 222 slides from the high point 224 to the lowest point 225, the spring 226 pulls the control arm 221 to the direction of the main shaft 201, so that the control arm 221 drives the control rod 217 to slide downward.

[0043] Thus, the second rotating shaft 209 drives the stirring rod 210 to rotate around the main shaft 201 and the second rotating shaft 209, and also drives the stirring rod 210 to move up and down, so that the stirring rod 210 stirs the raw materials in the upper and lower layers. Thus, the uniformity of stirring by the stirring rod 210 is further improved. In addition, when the main shaft 201 drives the first horizontal rod 202 to rotate, the main shaft 201 drives the pair of barrel wall scrapers 214 to rotate along the inner wall of the polymerization reactor 1 through the first horizontal rod 202, and the pair of barrel wall scrapers 214 scrapes the raw materials adhered to the inner wall of the polymerization reactor 1. After the polymerization reaction of the raw materials is completed, the raw materials are discharged from the discharge port 102. When the materials are discharged, the barrel wall scrapers 214 are driven by the rotation of the main shaft 201 to clean the materials on the inner wall of the polymerization reactor 1. In addition, the rotation of the arc-shaped scraper 215 removes the material flow on the bottom wall of the polymerization reactor 1 and pushes the material to the discharge port 102, effectively improving the discharge of the material and preventing the residual of the material flow.

[0044] It is apparent to those skilled in the art that the present disclosure is not limited to the details of the foregoing exemplary embodiments, and that the present disclosure can be implemented in other specific forms without departing from the spirit or essential characteristics of the disclosure. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the disclosure being defined by the appended claims rather than the foregoing description, and it is intended that all changes which come within the meaning and range of equivalency of the claims are resolvable as permissible under the patent laws.
