Description

Technical Field

[0001] This utility model relates to the field of nylon fiber production technology, specifically to a humidity conditioning device for nylon production. Background Technology

[0002] In the production of nylon, moisture conditioning is a crucial post-processing step. Nylon is a highly hygroscopic material, and its moisture content directly affects the stability of subsequent spinning, stretching, and texturing processes, as well as the quality of the final product, such as strength, elongation, and dyeing uniformity. Uneven moisture content or failure to meet process requirements can lead to problems such as increased breakage rate, inconsistent product performance, and decreased yield.

[0003] Currently, common humidity control methods often employ simple humidification rooms or drying rooms for static treatment. This involves introducing steam or spraying water mist into a closed space, allowing the nylon material to slowly absorb or release moisture under natural conditions. However, due to the temperature and humidity gradient differences at different locations within the space, the degree of moisture absorption or release varies between different batches, and even within the same batch of nylon material, resulting in poor quality stability. Furthermore, static treatment relies on natural air convection, leading to slow humidity transfer, long humidity control cycles, and extended equipment usage time, thus impacting overall production efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a humidity conditioning device for nylon production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a humidification device for nylon production, including a humidification box 1, a humidification mechanism 2 and a ventilation mechanism 3, wherein a drive mechanism 4 is provided on the top of the humidification box 1;

[0006] The humidifying chamber 1 is hinged to a closed door 5 on the front side. A temperature and humidity sensor 6 is fixed to the inner wall of the humidifying chamber 1. A central tube 7 passes through the top of the humidifying chamber 1. The central tube 7 is rotatably connected to the surface of the humidifying chamber 1 at the through point. Multiple material-holding mesh trays 8 for carrying nylon materials are fixed to the surface of the central tube 7. A support frame 11 is fixed to the bottom of the material-holding mesh tray 8. The support frame 11 is fixedly connected to the surface of the central tube 7. Multiple atomizing nozzles 9 are connected to the surface of the central tube 7. The atomizing nozzles 9 are located above the corresponding material-holding mesh trays 8. A rotary joint 10 is connected to the top of the central tube 7. A controller 16 is fixed to the surface of the closed door 5.

[0007] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0008] This invention uses a central tube to drive the rotation of the material-holding mesh tray, combined with directional airflow on both sides, to create a dynamic, three-dimensional, uniform humidity field. This ensures that all nylon materials in the same batch or even the same tray are consistently humidified, greatly improving product quality stability. At the same time, the equipment has high humidity control efficiency. The combination of atomized humidification and forced convection allows moisture to quickly and deeply penetrate the material layer, significantly shortening the humidity control cycle, improving production efficiency, and effectively solving the long-standing problems of uneven humidity control and low efficiency in nylon production.

[0015] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, a humidification device for nylon production includes a humidification box 1, a humidification mechanism 2, and a ventilation mechanism 3. A drive mechanism 4 is provided on the top of the humidification box 1.

[0017] The humidifying chamber 1 is hinged to a closed door 5 on the front side. A temperature and humidity sensor 6 is fixed to the inner wall of the humidifying chamber 1. A central tube 7 passes through the top of the humidifying chamber 1. The central tube 7 is rotatably connected to the surface of the humidifying chamber 1 at the through point. Multiple material-holding mesh trays 8 for carrying nylon materials are fixed to the surface of the central tube 7. A support frame 11 is fixed to the bottom of the material-holding mesh tray 8. The support frame 11 is fixedly connected to the surface of the central tube 7. Multiple atomizing nozzles 9 are connected to the surface of the central tube 7. The atomizing nozzles 9 are located above the corresponding material-holding mesh trays 8. A rotary joint 10 is connected to the top of the central tube 7. A controller 16 is fixed to the surface of the closed door 5.

[0018] Through the above technical solution, during operation, the humidification mechanism 2 provides water, the ventilation mechanism 3 provides airflow, and the drive mechanism 4 drives the central tube 7 to rotate. The central tube 7 receives liquid from the humidification mechanism 2 while rotating through the rotary joint 10 and distributes it to each atomizing nozzle 9 for spraying. The material-holding mesh tray 8 fixed on the central tube 7 rotates synchronously, and the nylon material on it continuously changes position. The temperature and humidity sensor 6 monitors the environmental parameters inside the chamber in real time and feeds them back to the controller 16. The controller 16 coordinates the humidification, ventilation, and drive actions to form an automated humidity control system. Through the rotation of the central tube 7 and the material-holding mesh tray 8, the humidity stratification and dead zones in the traditional static humidity control chamber are broken, so that all nylon materials can be periodically exposed to a uniform humidity and airflow environment, ensuring the uniformity of humidity control.

[0019] The humidification mechanism 2 includes a water storage tank 201, a humidification pump 202 connected to the surface of the water storage tank 201, a water delivery pipe 203 connected to the delivery end of the humidification pump 202, and one end of the water delivery pipe 203 connected to the rotary joint 10.

[0020] With the above technical solution, when humidifying, the controller 16 starts the humidification pump 202, which draws water from the water tank 201 and pumps it into the fixed end of the rotary joint 10 through the water delivery pipe 203. The water then enters the continuously rotating central tube 7 through the rotating end of the rotary joint 10, and is finally atomized and sprayed out by the atomizing nozzle 9 on the wall of the central tube 7.

[0021] The ventilation mechanism 3 includes a hot air blower 301 and a diversion shell 302. There are two diversion shells 302. The diversion shells 302 are fixed to the left and right sides of the inner wall of the humidification box 1. Multiple air outlets 304 are connected to the surface of the diversion shells 302. A diversion pipe 303 is connected to the surface of the hot air blower 301. The diversion pipe 303 passes through the humidification box 1 and is connected to the diversion shells 302.

[0022] Through the above technical solution, during operation, the hot air blower 301 generates airflow with a certain temperature. The airflow is evenly distributed to the two vertically placed distribution shells 302 on the left and right through the distribution pipe 303. The distribution shell 302 acts as a static pressure chamber, allowing the airflow to be smoothly ejected from the multiple air outlets 304 distributed on its surface. This forms two vertical and uniform airflow curtains inside the humidification chamber 1. Through the combination of the distribution shell 302 and the multiple air outlets 304, a concentrated airflow is dispersed into multiple fine and uniform airflows, avoiding local over-drying or uneven humidification caused by strong wind blowing from a single point. This ensures that every material tray 8 from both sides of the chamber to the central area is blown by a uniform and gentle airflow, greatly improving the uniformity of humidification.

[0023] The air outlet 304 is located above the corresponding material receiving tray 8. The opening direction of the air outlet 304 is inclined at an angle of 30-60 degrees to the horizontal direction and faces the material receiving tray 8 below.

[0024] Through the above technical solution, the air outlet 304 installed above the material holding mesh tray 8 does not have a horizontal or vertical downward air outlet direction, but rather adopts an inclined downward angle, directly aimed at the rotating material holding mesh tray 8 and the nylon material on it. In this way, the airflow from both sides can cross and cover the surface of the material, thereby "pressing" and "enveloping" the water mist sprayed from the atomizing nozzle 9 onto and enveloping the nylon material, forcing the moisture to fully contact and penetrate the surface of the material, greatly enhancing the heat and mass exchange efficiency, and avoiding waste caused by the disorderly dispersion of water mist in the box and condensation on the box wall.

[0025] A water collection shell 12 is fixed to the bottom of the inner wall of the humidifier box 1. The bottom of the central tube 7 is rotatably connected to the bottom of the inner wall of the water collection shell 12. A drain valve 13 is fixed to the surface of the humidifier box 1. The drain valve 13 is connected to the water collection shell 12.

[0026] Through the above technical solution, during the operation of the equipment, a small amount of excess water mist that is not absorbed by the nylon material in time may condense into water droplets, or when the equipment needs to be cleaned, the wastewater generated will drip down into the water collection shell 12 at the bottom of the humidification box 1. When drainage is required, the drain valve 13 can be opened to drain the accumulated liquid in the water collection shell 12 out of the box.

[0027] The top of the humidifier box 1 is connected to an exhaust pipe 14, and the top of the exhaust pipe 14 is connected to a solenoid valve 15.

[0028] Through the above technical solution, when the temperature and humidity sensor 6 detects that the humidity inside the humidification chamber 1 is too high, exceeding the process setting value, or when the humidity adjustment process is completed and the humidity inside the chamber needs to be reduced quickly, the controller 16 will instruct the solenoid valve 15 to open and increase the heat of the hot air blower 301, thereby achieving the purpose of dehumidification.

[0029] The drive mechanism 4 includes a square profile plate 401, which is fixed to the top of the humidification chamber 1. A drive motor 402 is fixed to the top of the square profile plate 401. The output shaft of the drive motor 402 passes through the square profile plate 401 and is fixed with a rotating shaft 403. The bottom end of the rotating shaft 403 is rotatably connected to the top of the humidification chamber 1. A sprocket 404 is fixed above both the rotating shaft 403 and the surface of the central tube 7. The left and right sprockets 404 are connected by chain drive.

[0030] With the above technical solution, after the drive motor 402 starts, its output shaft drives the rotating shaft 403 to rotate, and the sprocket 404 fixed on the rotating shaft 403 rotates accordingly. The power is transmitted to another sprocket 404 fixed on the central tube 7 through the chain, thereby driving the central tube 7 and all the material-holding mesh trays 8 on it to rotate slowly together.

[0031] Working principle: The operator places the nylon material evenly on each of the feeding trays 8, closes the sealing door 5, sets the required process parameters through the controller 16, and starts the equipment. The drive motor 402 drives the central tube 7 and all the feeding trays 8 to rotate slowly and steadily through the sprocket 404 and chain drive, causing the material to continuously change position in the horizontal plane. At the same time, the temperature and humidity sensor 6 monitors the environment inside the chamber in real time. When humidification is required, the controller 16 starts the humidification pump 202, pumping water from the water tank 201 into the rotating central tube 7 through the water delivery pipe 203 and the rotary joint 10. Finally, the water is atomized and sprayed out by the atomizing nozzles 9 distributed vertically along the central tube 7. At the same time, the hot air blower 30 of the ventilation mechanism 3... Upon startup, the generated temperature-controlled airflow is delivered through the diversion pipe 303 to the diversion shells 302 on both sides of the chamber, and then ejected through multiple air outlets 304 set at specific angles, forming a uniform and directional airflow that blows towards the rotating material. This airflow precisely guides and envelops the atomized water mist in the material, forcing heat and moisture exchange, while also driving air circulation within the chamber to prevent humidity stratification. If the humidity inside the chamber is too high, the controller 16 can open the solenoid valve 15 on the exhaust pipe 14 to remove moisture. The entire humidity control process integrates three major elements: dynamic rotation of the material, central atomized humidification, and dual-sided directional airflow, forming a three-dimensional, uniform, and efficient humidity control environment until the preset process requirements are met. This solution solves the technical problems of poor uniformity and low efficiency in traditional static humidity control by controlling mechanical motion and gas-liquid two-phase flow, achieving high-quality and high-efficiency humidity control for nylon materials.
