Description

Technical Field

[0001] This invention relates to the field of chemical fiber production technology, and in particular to a chemical fiber drying apparatus. Background Technology

[0002] In the production of chemical fibers, the drying process is a crucial step in ensuring fiber quality. Chemical staple fibers typically contain some moisture and require effective drying to meet the quality requirements of subsequent processing. Traditional drying methods primarily employ hot air drying, which involves heating air and bringing it into full contact with the fibers to evaporate the moisture on the fiber surface. However, traditional hot air drying suffers from significant drawbacks, including low drying efficiency, high energy consumption, and uneven drying.

[0003] During the drying process, the physical structure and chemical properties of chemical fibers are highly sensitive to temperature changes. Excessively high drying temperatures can cause the fiber surface to crust over, hindering the escape of internal moisture and resulting in a "dry outside, wet inside" phenomenon. Conversely, excessively low drying temperatures prolong drying time and reduce production efficiency. Furthermore, different batches of chemical fibers vary in moisture content and fiber fineness, thus requiring different drying processes. Traditional drying equipment typically employs a single drying mode, making it difficult to adapt to the drying needs of different types of chemical fibers, leading to unstable drying quality and poor product consistency.

Detailed Implementation

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Please see Figures 1 to 7 The present invention provides a chemical fiber drying device, including a support assembly, a conveying assembly, and a drying assembly. The support assembly includes a base 101, a support frame 102, and a processing box 103. The support frame 102 is disposed on the base 101, and the processing box 103 is disposed on the support frame 102.

[0027] The conveying assembly includes a conveying roller 104, a conveying elastic mesh belt 105, a turning structure 106, an auxiliary support structure 107, and a turning structure 108. The conveying roller 104 is rotatably mounted inside the processing box 103, and the conveying elastic mesh belt 105 is mounted on the conveying roller 104. The turning structure 106 is located on one side of the conveying elastic mesh belt 105 and is used to drive the conveying elastic mesh belt 105 to move up and down. The auxiliary support structure 107 is located on the turning structure 106 and is used to compensate for the tension difference generated by the up-and-down movement of the conveying elastic mesh belt 105. The turning structure 108 is rotatably mounted above the conveying elastic mesh belt 105 and is used to turn over the lifted fibers.

[0028] The drying assembly includes an air-drying module 109, a microwave-assisted drying module 110, and a temperature monitoring module 111. The air-drying module 109 is disposed within the processing chamber 103 and is used to drive the flow of hot air within the processing chamber 103. The microwave-assisted drying module 110 generates microwaves to heat the fibers. The temperature monitoring module 111 controls the power of the air-drying module 109 and the microwave-assisted drying module 110.

[0029] In this embodiment, the support assembly is used to support and bear the various components of the entire device. The base 101 is made of high-strength steel and serves as the basic structure of the entire device, providing a stable installation platform to ensure the stability of the equipment during operation and to withstand the entire weight of the processing box 103 and its internal components. The support frame 102 is mounted on the base 101 and is made of steel profiles, bearing the weight of the processing box 103 and its internal components, and has good structural strength and rigidity. The processing box 103 is mounted on the support frame 102, forming a closed drying space that provides controllable environmental conditions for the drying of chemical fibers. The box body is made of heat-insulating material to reduce heat loss.

[0030] The conveying assembly is used to convey and agitate the chemical fibers, ensuring full contact between the drying medium and the fibers. The conveying rollers 104 are rotatably mounted on both sides of the inner wall of the processing box 103 via bearings, and are continuously rotated by a drive motor, driving the fibers forward within the processing box 103. The conveying elastic mesh belt 105 is mounted on the conveying rollers 104 and is woven from stainless steel wire, possessing good air permeability and elasticity, capable of both bearing the fibers and ensuring the flow of the drying medium.

[0031] The actuating structure 106 is disposed on one side of the conveying elastic mesh belt 105 and includes a cam 201, a spring 202, a drive motor 203, and a sliding plate 204. The sliding plate 204 is slidably disposed on the processing box 103 and located on one side of the conveying elastic mesh belt 105. The spring 202 is disposed between the sliding plate 204 and the processing box 103, providing elastic support. The cam 201 is disposed below the sliding plate 204, and the output end of the drive motor 203 is connected to the cam 201. When the drive motor 203 drives the cam 201 to rotate, the contour of the cam 201 pushes the sliding plate 204 to move up and down, and the spring 202 provides a restoring force, enabling the sliding plate 204 to slide smoothly up and down periodically, causing the conveying elastic mesh belt 105 to undulate. The actuating structure 106 also includes a guide plate 205, which is fixed on the processing box 103 and slidably connected to the sliding plate 204 to guide the movement trajectory of the sliding plate 204, ensuring that it moves in a predetermined direction and preventing the sliding plate 204 from deviating or getting stuck.

[0032] The sliding plate 204 includes a plate body 206 and multiple protrusions 207, which are disposed on the plate body 206. The protrusions 207 are used to lift the fibers at preset intervals to improve heat dissipation space and efficiency. When the protrusions 207 rise with the sliding plate 204, they can lift the fibers, forming a larger heat dissipation space and increasing the contact area between hot air and fibers. The plate body 206 is provided with multiple ventilation holes 208 to ensure that hot air can penetrate the plate body 206 and heat the bottom of the fibers, thereby achieving double-sided drying of the fibers.

[0033] The auxiliary support structure 107 is disposed on the actuating structure 106 to compensate for tension changes in the conveyor elastic mesh belt 105 during undulation. The auxiliary support structure 107 includes a connecting rod 209, a rotating rod 210, a tension roller 211, and a locking device. The connecting rod 209 is fixed to the plate 206 and moves synchronously with the sliding plate 204; the rotating rod 210 is rotatably disposed on the connecting rod 209 and can swing within a certain angle range; the tension roller 211 is rotatably disposed on the rotating rod 210 and is located on one side of the conveyor elastic mesh belt 105. When the conveyor elastic mesh belt 105 moves up and down, the tension roller 211 adjusts its position accordingly to maintain a constant mesh belt tension; the locking device is used to lock the position of the rotating rod 210 after it has been adjusted to the correct position.

[0034] The locking device includes a friction disc 213, a clamping rod 214, and a control unit 215. The friction disc 213 is fixed to the rotating rod 210 and rotates together with the rotating rod 210; the clamping rod 214 is slidably disposed on one side of the friction disc 213; the control unit 215 is used to control the clamping rod 214 to move closer to or away from the friction disc 213. When it is necessary to adjust the position of the tension roller 211, the control unit 215 controls the clamping rod 214 to move away from the friction disc 213, releasing the locking state and allowing the rotating rod 210 to rotate freely; after adjustment, the control unit controls the clamping rod 214 to move closer to the friction disc 213, locking the rotating rod 210 through friction to prevent the position of the tension roller 211 from changing during operation.

[0035] The tumbling structure 108 is rotatably disposed above the conveying elastic mesh belt 105 to further enhance the tumbling effect on the fibers. The tumbling structure 108 includes an air inlet pipe 301, a heating structure 302, an air pump 303, a rotating head 304, and a tumbling plate 305. The rotating head 304 is rotatably disposed on the processing box 103, driving the tumbling plate 305 to rotate; the tumbling plate 305 has a hollow structure and an inclined air outlet 306 is provided on the edge of the tumbling plate 305, the inclined air outlet 306 communicating with the rotating head 304; the air inlet pipe 301 is disposed on one side of the rotating head 304, the air pump 303 is connected to the air inlet pipe 301, driving hot air into the rotating head 304; the heating structure 302 is used to heat the air in the air inlet pipe 301. During operation, the air pump 303 sends hot air into the rotating head 304 through the air inlet pipe 301. The hot air is ejected from the inclined air outlet 306, forming multiple inclined airflows that push and tumble the fibers, causing them to tumble continuously. At the same time, the reverse pushing action of the airflow can drive the turning plate 305 to rotate, thereby improving the turning effect, preventing fiber accumulation and adhesion, and ensuring uniform drying.

[0036] The drying assembly is used for efficient drying of chemical fibers. The air-drying module 109 includes a heater 401, a blower 402, and a circulating air duct 403. The heater 401 is disposed inside the processing chamber 103 to generate heat; the blower 402 is disposed on one side of the heater 401 to deliver hot air into the processing chamber 103; the circulating air duct 403 is disposed on one side of the processing chamber 103 to create a circulating flow of hot air within the processing chamber 103, thereby improving thermal efficiency and reducing heat loss.

[0037] The microwave generator 404 serves as the core energy source, and its implementation employs a multi-source parallel feeding technology. To meet the drying requirements of high moisture content chemical fibers, an industrial-grade high-power magnetron array is selected for the system. Considering the microwave penetration depth and drying efficiency of the fiber layer, the preferred operating frequency is 2450MHz (suitable for conventional drying) or 915MHz (suitable for large penetration depth and high load conditions).

[0038] In a preferred embodiment, the core component of the microwave generator 404, the magnetron, is a Panasonic 2M244-M1 or LG2M244 industrial-grade magnetron. This model has a single-tube rated power of 2kW to 3kW, and features a long lifespan (>5000 hours) and high stability, making it suitable for continuous industrial production.

[0039] The power supply for the control system uses a half-bridge switching power supply, which, compared to traditional leakage inductance transformers, features a high power factor, small size, and fast response speed. The power supply supports 0-100% linear power adjustment, facilitating real-time adjustment of output energy based on temperature feedback.

[0040] A microwave radiating antenna 405 is installed inside the processing box 103, specifically designed to eliminate "cold spots" and "hot spots" in microwave heating. The microwave radiating antenna 405 is either a waveguide slot array antenna or a horn antenna. In one specific embodiment, a WR284 standard waveguide antenna (corresponding to a 2450MHz frequency) is selected, with its ports fitted with PTFE shielding to prevent chemical fiber dust or moisture condensation from contaminating the waveguide interior and ensuring microwave transmission efficiency. The antennas are arranged in a three-dimensional, staggered array on the inner walls (top, side walls, and bottom) of the processing box 103. Through electromagnetic field simulation, the position and polarization direction of each antenna port are adjusted to create a multimode coupled interference field within the processing box, ensuring consistent microwave energy density received by all parts of the fiber during transmission and achieving synchronous drying from the inside to the outside of the fiber. Comb-shaped microwave suppressors or ferrite absorption loads are installed at the inlet and outlet of the processing box 103 to strictly control microwave leakage within the limits of the national standard (GB5959.6), ensuring operational safety.

[0041] The temperature monitoring module 111 includes a temperature detection unit 406 and a temperature control unit 407, which are used to achieve precise temperature control in a strong electromagnetic field environment.

[0042] Because of the strong electromagnetic interference in the microwave field, ordinary thermocouples or resistance thermometers will generate induced current, which will cause measurement distortion or even damage. Therefore, this embodiment adopts an anti-interference temperature measurement scheme.

[0043] A fiber optic temperature sensor is employed. In a preferred embodiment, the FISOFOT-L-SD series fiber optic temperature sensor is selected. This sensor probe is made of an insulating medium such as quartz glass, contains no metal parts, and is completely immune to microwave interference. The probe is directly inserted into the fiber layer inside the processing chamber 103 to acquire the core temperature of the fiber in real time. As an auxiliary measure, an infrared thermal imager (such as an Optris PI640) is installed in the viewing window on the top of the processing chamber 103. This device monitors the temperature distribution field on the fiber surface through an infrared optical lens, which can visually identify areas of uneven drying and provide data support for adjusting the antenna power.

[0044] The temperature control unit 407 is responsible for receiving temperature data and executing PID closed-loop control logic. A Siemens SIMATIC S7-1200 series PLC (specific model such as CPU1214CDC / DC / DC) is selected as the core controller. This PLC has a high-speed analog input channel and can receive 4-20mA standard signals from fiber optic temperature transmitters (such as FISOFTI-10) in real time.

[0045] The PLC reads the temperature data inside the processing chamber in real time through the analog input module. Internally, the PLC runs a PID control algorithm, comparing the collected temperature with the set temperature range (e.g., 80℃-100℃). When the temperature exceeds the set upper limit (e.g., >100℃), the PLC outputs a control signal, reducing the anode current of the microwave power supply through the analog output module, thereby reducing the output power of the microwave generator 404; simultaneously, it increases the fan frequency of the drying module 109 or reduces its heater power. When the temperature falls below the set lower limit (e.g., <80℃), the PLC automatically increases the power of the microwave generator 404 to ensure drying efficiency. When the temperature monitoring unit detects abnormally high temperatures (e.g., >120℃, posing a risk of fiber carbonization), the PLC immediately triggers an emergency stop command, cutting off the power supply to the microwave generator and activating an audible and visual alarm.

[0046] After the system starts up, the conveyor belt delivers the high-moisture-content chemical fibers into the processing chamber 103. The microwave generator 404 (Panasonic 2M244-M1) is activated, emitting 2450MHz microwaves into the chamber via a WR284 waveguide antenna. The microwaves penetrate the fibers, causing the internal water molecules to vibrate rapidly and generate heat. Simultaneously, a FISO fiber optic sensor monitors the fiber temperature in real time and transmits the data to an S7-1200 PLC. The PLC dynamically adjusts the microwave power and hot air temperature based on the real-time temperature, ensuring the drying process remains within the optimal temperature range for efficient and uniform drying.

[0047] The chemical fiber drying device provided by this invention achieves thorough agitation and uniform drying of chemical fibers through the cooperation of the agitation structure 106 and the tumbling structure 108; it achieves all-round drying from the outside to the inside of the fiber through the combined action of the air drying module 109 and the microwave-assisted drying module 110; and it achieves precise adjustment of drying parameters through the intelligent control of the temperature monitoring module 111. This device has advantages such as high drying efficiency, uniform drying, low energy consumption, and strong adaptability, and is suitable for drying various types of chemical fibers such as polyester, nylon, acrylic, and polypropylene, making it suitable for large-scale industrial production.
