Description

Technical Field

[0001] This utility model relates to the field of chemical fiber nylon production technology, and in particular to a stirring device for chemical fiber nylon production that is easy to adjust speed. Background Technology

[0002] For example, Chinese patent CN215202870U discloses a stirring device for the production of synthetic nylon. By starting a third motor, the cutting shaft rotates, which in turn causes the cutting blades to rotate, thereby cutting and crushing the raw materials that become kinked during the stirring process, thus avoiding the kinking between the components and affecting the mixing effect.

[0003] Because the raw material of synthetic nylon has a certain viscosity, and different stirring speeds are required at different stages to control the reaction rate, the stirring device in the above application only uses a spiral feeding blade for feeding and stirring. Its stirring mode is simple, and the relatively limited speed range results in poor stirring and mixing effect, which cannot meet the diverse needs of synthetic nylon production processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stirring device for the production of synthetic nylon that is easy to adjust in speed. It solves the technical problem that the existing technology has a single stirring mode and a limited speed adjustment range, resulting in poor stirring and mixing effects. It achieves the goal of targeted speed adjustment and stirring according to different stages of synthetic nylon production, thereby improving stirring efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a stirring device for the production of chemical fiber nylon that is easy to adjust speed, including support legs installed at the four corners of the bottom of the reaction vessel, a stirring mechanism for stirring and mixing chemical fiber nylon is provided inside the reaction vessel, and a circulation mechanism for circulating and stirring the chemical fiber nylon at the bottom of the reaction vessel is provided on the reaction vessel.

[0006] The stirring mechanism includes a drive gear installed at the center of the top of the reactor, and driven gears symmetrically meshing on the left and right sides of the drive gear. A stirring shaft extending into the reactor is installed at the bottom of the driven gear, and multiple bushings are vertically and equidistantly installed on the stirring shaft. An annular stirring rod is rotatably connected inside the bushings. A drive motor for driving the drive gear to rotate is installed on the top of the reactor via a bracket. A turning component for secondary turning of the chemical fiber nylon is provided on the annular stirring rod. A cutting component for cutting and crushing kinked raw materials is provided on the drive gear.

[0007] A further improvement is that the material-turning assembly includes multiple stirring rods mounted on an annular stirring rod, and a material-turning plate is inclinedly mounted on the outer end of the stirring rods.

[0008] A further improvement is that the cutting assembly includes a cutting shaft mounted on the bottom of the drive gear and extending into the reactor, and multiple sets of cutting blades are vertically and equidistantly mounted on the cutting shaft, with the cutting blades located between two adjacent sets of annular stirring rods.

[0009] A further improvement is that a feed pipe is installed at the top of the reactor, a discharge pipe is installed at the bottom of the reactor, and an electric sealing valve is installed on the discharge pipe.

[0010] A further improvement is that installation chambers are provided on the left and right sides of the inner wall of the reactor, and electric heating plates are installed in the installation chambers. A controller is installed on the front of the reactor, and the stirring mechanism, electric sealing valve and electric heating plate are all electrically connected to the controller.

[0011] A further improvement is that the circulation mechanism includes a feeding pipe installed on the back of the reactor, and a feeding shaft is rotatably connected in a rotating hole on the feeding pipe. A feeding auger is installed on the feeding shaft. Both the upper and lower ends of the connection between the feeding pipe and the reactor are provided with feeding ports. A pulley is installed on the top of the feeding shaft and the output end of the drive motor, and the two pulleys are connected by a transmission belt.

[0012] By means of the above technical solution, this utility model provides a stirring device for the production of synthetic nylon fibers that is easy to adjust in speed, which has at least the following beneficial effects:

[0013] 1. This utility model uses a drive gear to drive a driven gear that meshes with it to rotate, thereby driving the stirring shaft to rotate. At this time, the annular stirring rod inside the bushing on the stirring shaft rotates accordingly, which fully mixes and stirs the chemical fiber nylon raw material in the reactor. Moreover, the annular stirring rod rotates inside the bushing due to the resistance of the chemical fiber nylon raw material, which further improves the stirring effect.

[0014] 2. With the rotation of the annular stirring rod, the stirring connecting rod and the material turning plate on the annular stirring rod will rotate, which will turn the chemical fiber nylon raw material in the reactor, further improving the stirring and mixing effect.

[0015] 3. As the drive gear rotates, the cutting shaft at its bottom rotates, which in turn drives the cutting blade on the cutting shaft to rotate. Since the cutting blade is located between two adjacent sets of annular stirring rods, it cuts the kinked synthetic nylon raw material.

[0016] 4. This utility model uses the cooperation of pulley and transmission belt to drive the feeding shaft to rotate, thereby driving the feeding auger to rotate, and feeding the chemical fiber nylon raw material at the bottom of the reactor to the top of the feeding pipe, and then flowing back into the top of the reactor from the top feed port, thereby realizing the circulating feeding and stirring of the chemical fiber nylon raw material, and further improving the stirring efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] To address the shortcomings of current technologies, such as limited mixing modes and speed ranges leading to poor mixing effects, this embodiment provides a speed-adjustable mixing device for the production of synthetic nylon fibers. Please refer to [reference needed]. Figures 1-5 This embodiment provides a speed-adjustable stirring device for the production of synthetic nylon fibers, which can adjust the stirring speed according to different stages of synthetic nylon production to improve stirring efficiency. The speed-adjustable stirring device includes support legs 2 installed at the four corners of the bottom of a reactor 1. A stirring mechanism 3 is installed inside the reactor 1 to mix the synthetic nylon fibers. A circulation mechanism 4 is installed on the reactor 1 to circulate and stir the synthetic nylon fibers at the bottom of the reactor 1. The stirring mechanism 3 thoroughly mixes the synthetic nylon raw materials in the reactor 1, and the stirring speed is adjusted to adapt to different reaction processes. The circulation mechanism 4 transports the synthetic nylon raw materials from the bottom of the reactor 1 to the top of the reactor 1, achieving circulatory conveying and stirring of the synthetic nylon raw materials, thus improving stirring efficiency.

[0033] Because existing technologies have a single stirring mode and a limited speed range, resulting in poor mixing effects, this device is equipped with a stirring mechanism 3. The stirring mechanism 3 includes a drive gear 31 installed at the center of the top of the reactor 1, with driven gears 32 symmetrically meshed on both sides of the drive gear 31. A stirring shaft 33 extending into the reactor 1 is installed at the bottom of the driven gears 32, and multiple bushings 34 are vertically and equidistantly installed on the stirring shaft 33. An annular stirring rod 35 is rotatably connected inside the bushings 34. A drive motor 36 that drives the drive gear 31 to rotate is installed on the top of the reactor 1 via a bracket. The annular stirring rod 35... The reactor is equipped with a material turning component 37 for secondary turning of the chemical fiber nylon, and a cutting component 38 for cutting and crushing the kinked material on the drive gear 31. When the drive motor 36 is started, it drives the drive gear 31 to rotate, which in turn drives the driven gear 32 connected to it to rotate, thereby driving the stirring shaft 33 at the bottom of the driven gear 32 to rotate. At this time, the annular stirring rod 35 in the bushing 34 on the stirring shaft 33 rotates accordingly to fully mix and stir the chemical fiber nylon material in the reactor 1. The annular stirring rod 35 rotates in the bushing 34 due to the resistance of the chemical fiber nylon material, which further improves the stirring effect.

[0034] To further improve the mixing effect, the device is also equipped with a material turning component 37. The material turning component 37 includes multiple stirring rods 371 installed on the annular stirring rod 35, and a material turning plate 372 is installed at an angle on the outer end of the stirring rods 371. As the annular stirring rod 35 rotates, it drives the stirring rods 371 and the material turning plate 372 on the annular stirring rod 35 to rotate, turning the chemical fiber nylon raw material in the reactor 1, which further improves the mixing effect.

[0035] Because the synthetic nylon raw material is prone to kinking during the mixing process, which reduces the mixing effect, the device is also equipped with a cutting component 38. The cutting component 38 includes a cutting shaft 381 installed at the bottom of the drive gear 31 and extending into the reactor 1. Multiple sets of cutting blades 382 are vertically and equidistantly installed on the cutting shaft 381. The cutting blades 382 are located between two adjacent sets of annular stirring rods 35. As the drive gear 31 rotates, it drives the cutting shaft 381 at its bottom to rotate, thereby driving the cutting blades 382 on the cutting shaft 381 to rotate. Since the cutting blades 382 are located between two adjacent sets of annular stirring rods 35, they can cut the kinked synthetic nylon raw material.

[0036] A feed pipe 39 is installed at the top of the reactor 1, and a discharge pipe 310 is installed at the bottom of the reactor 1. An electric sealing valve 311 is installed on the discharge pipe 310. The chemical fiber nylon raw material is introduced into the reactor 1 through the feed pipe 39. After the chemical fiber nylon raw material is stirred and mixed, the electric sealing valve 311 is activated, and the chemical fiber nylon raw material is discharged through the discharge pipe 310.

[0037] Since different temperatures are required at different stages of the production process of chemical fiber nylon raw materials, the device has installation chambers on the left and right sides of the inner wall of the reactor 1, and electric heating plates 312 are installed in the installation chambers. A controller 313 is installed on the front of the reactor 1, and the stirring mechanism 3, electric sealing valve 311 and electric heating plate 312 are all electrically connected to the controller 313. The controller 313 controls the heating temperature of the chemical fiber nylon raw materials in the reactor 1 by the electric heating plate 312, and controls the speed of the drive motor 36, thereby controlling the stirring rate, so as to make targeted adjustments for different stages of chemical fiber nylon production.

[0038] Example 2

[0039] Based on Example 1, such as Figures 1-5As shown, since the raw material of chemical fiber nylon that settles at the bottom of the reactor 1 cannot be fully stirred during the production of chemical fiber nylon, the device is also equipped with a circulation mechanism 4. The circulation mechanism 4 includes a feeding pipe 41 installed on the back of the reactor 1, and a feeding shaft 42 is rotatably connected to the rotating hole opened on the feeding pipe 41. A feeding auger 43 is installed on the feeding shaft 42. Both the upper and lower ends of the connection between the feeding pipe 41 and the reactor 1 are provided with feeding ports 44. The top of the feeding shaft 42 and the output end of the drive motor 36 are respectively equipped with pulleys 45, and the two... The pulleys 45 are connected by a transmission belt 46. While the drive motor 36 drives the annular stirring rod 35 to stir, the pulleys 45 and the transmission belt 46 work together to drive the feeding shaft 42 in the feeding pipe 41 to rotate. This drives the feeding auger 43 to rotate and auger the chemical fiber nylon raw material at the bottom of the reactor 1 that flows into the feeding pipe 41 through the bottom feed port 44 to the top of the feeding pipe 41. The raw material then flows back into the top of the reactor 1 from the top feed port 44, thus realizing the circulating feeding and stirring of the chemical fiber nylon raw material and further improving the stirring efficiency.
