Description

Technical Field

[0001] This utility model relates to the field of fiber production equipment, and in particular to a drying device for the production of ultra-high molecular weight polyethylene composite fibers. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) is a linear thermoplastic engineering plastic with excellent comprehensive properties. UHMWPE fiber is a high-performance fiber with a strong ability to absorb energy, thus exhibiting outstanding impact resistance. UHMWPE composite fiber possesses excellent properties such as high strength, high modulus, wear resistance, and corrosion resistance.

[0003] The particle size of ultra-high molecular weight polyethylene (UHMWPE) composite fibers is generally classified into three forms: powder, granules, and fibers. Due to their excellent properties such as high strength, high modulus, and wear resistance, UHMWPE composite fibers are widely used in high-performance textiles and other fields. In the raw material production process, the drying device is a key link to ensure fiber quality, mainly removing residual solvents or moisture from the fibers. However, existing drying devices have some shortcomings. Traditional drying devices are not effective at turning over materials and mostly rely on hot air for drying. During the drying process, the fibers pile up together and cannot fully contact the heat source, and even local accumulation may occur. This makes it difficult for the moisture inside the fibers to evaporate effectively, resulting in the outer layer being over-dried while the inner layer is not dry. The drying uniformity is poor, which reduces the drying efficiency and affects product quality. To address these issues, we propose a drying device for the production of UHMWPE composite fibers. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the production of ultra-high molecular weight polyethylene composite fibers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying device for producing ultra-high molecular weight polyethylene composite fibers includes an outer shell. A drying cylinder is fixedly connected to the inner wall of the outer shell. A hot air heating element and an infrared heater are fixedly installed on the outer surface of the outer shell. A frame is fixedly connected to the bottom surface of the drying cylinder. A servo motor is fixedly installed on the outer surface of the frame. A drive rod is fixedly connected to the output end of the servo motor. A spiral conveying blade is fixedly connected to the outer surface of the drive rod. A transmission rod is fixedly connected to the top end of the drive rod. Two connecting rods are fixedly connected to the outer surface of the transmission rod. A scraper is fixedly connected to the bottom end of each connecting rod.

[0007] In a further embodiment, a guide rail is fixedly connected to the inner wall of the drying cylinder, and both ends of the transmission rod are slidably connected to the inside of the guide rail.

[0008] In a further embodiment, a protective cover is hinged to the outer surface of the drying cylinder, and a square cover is hinged to the front of the outer shell.

[0009] In a further embodiment, a plurality of exhaust valves are fixedly installed on the upper surface of the outer casing, and two support columns are fixedly connected to the bottom surface of the outer casing.

[0010] In a further embodiment, a controller is fixedly mounted on the front of the outer casing, and a side shield is fixedly connected to the top of the drying cylinder.

[0011] In a further embodiment, the hot air heating element includes a circular cylinder fixedly installed on the upper surface of the outer casing, a fan fixedly installed on the inner wall of the circular cylinder, an air heater fixedly connected to the bottom surface of the circular cylinder, and the fan located at the air inlet of the air heater.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a servo motor to drive a drive rod to rotate, and a spiral conveyor blade pushes the material at the bottom upwards. The transmission rod, connecting rod, and scraper plate break up and tumble the material, and scrape off the material adhering to the inner wall of the drying cylinder. This allows the fibers to move continuously inside the drying cylinder, fully contacting the hot air generated by the hot air heater and the infrared radiation from the infrared heater. This ensures that the material is heated evenly from all directions, achieving efficient and uniform drying. The hot air heated by the air heater is sent into the drying cylinder by the fan of the hot air heater, working synergistically with the infrared radiation from the infrared heater to heat and dry the material from multiple dimensions, improving drying efficiency and shortening drying time.

[0022] Please see Figure 1-4This utility model discloses a drying device for the production of ultra-high molecular weight polyethylene composite fibers, comprising an outer shell 1, a drying cylinder 8 fixedly connected to the inner wall of the outer shell 1, a hot air heating element 6 and an infrared heater 7 fixedly installed on the outer surface of the outer shell 1, a frame 10 fixedly connected to the bottom surface of the drying cylinder 8, a servo motor 11 fixedly installed on the outer surface of the frame 10, a drive rod 13 fixedly connected to the output end of the servo motor 11, a spiral conveying blade 14 fixedly connected to the outer surface of the drive rod 13, a transmission rod 15 fixedly connected to the top end of the drive rod 13, and two connecting rods 16 fixedly connected to the outer surface of the transmission rod 15. A scraper 17 is fixedly connected to the bottom end of each connecting rod 16. The servo motor 11, drive rod 13, and spiral conveying blade 14 realize the conveying of materials, the transmission rod 15, connecting rod 16 and scraper 17 complete the turning of materials, and the hot air heating element 6 and infrared heater 7 provide the drying heat source, laying the foundation for uniform drying of materials.

[0023] The inner wall of the drying cylinder 8 is fixedly connected to a guide rail 18. Both ends of the transmission rod 15 are slidably connected to the inside of the guide rail 18. The guide rail 18 cooperates with the transmission rod 15 to provide stable guidance for the rotation of the transmission rod 15, preventing it from deviating or shaking during rotation, and ensuring that the scraper 17 can stably and effectively turn the material. The outer surface of the drying cylinder 8 is hinged to a protective cover 9. The front of the outer shell 1 is hinged to a square cover 2. The protective cover 9 can prevent the material from splashing out of the drying cylinder 8 during the drying process. The square cover 2 makes it easy to open the outer shell 1 to add the material to be dried, and it is also easy to open the protective cover 9 so that the operator can remove the material inside the drying cylinder 8.

[0024] Multiple exhaust valves 5 are fixedly installed on the upper surface of the outer casing 1, and two support columns 3 are fixedly connected to the bottom surface of the outer casing 1. The exhaust valves 5 can promptly discharge the moisture generated during the drying process, maintain air circulation inside the drying cylinder 8, and prevent moisture accumulation from affecting the drying effect. The support columns 3 increase the contact area between the outer casing 1 and the ground, improve the stability of the drying device, and prevent the device from shaking or tilting during operation. A controller 4 is fixedly installed on the front of the outer casing 1, and a side baffle 12 is fixedly connected to the top of the drying cylinder 8. The controller 4 can centrally control the operation of components such as the servo motor 11, the hot air heating element 6, and the infrared heater 7, allowing operators to adjust parameters according to material characteristics and drying requirements. The side baffle 12 can prevent material from overflowing from the top of the drying cylinder 8 during conveying and turning, ensuring that the material is fully dried in the drying area. The hot air heating element 6 includes a fixed... A circular cylinder 601 is installed on the upper surface of the outer casing 1. A fan 602 is fixedly installed on the inner wall of the circular cylinder 601. An air heater 603 is fixedly connected to the bottom surface of the circular cylinder 601, and the fan 602 is located at the air inlet of the air heater 603. The air heater 603 can be heated by an electric heating tube. After the air is heated to the set temperature, it is sent into the drying chamber by the fan 602. The infrared heater 7 adopts a high-intensity infrared heating tube. The infrared radiation emitted by the infrared heating tube can directly act on the fiber surface, so that the inside and surface of the fiber are heated at the same time, improving the heating efficiency. The fan 602 of the hot air heating element 6 sends the hot air heated by the air heater 603 into the drying cylinder 8, providing a uniform hot air heat source for the material. It works in synergy with the infrared heater 7 to accelerate the evaporation rate of the material moisture, improve the drying efficiency, and make the material more evenly heated.

[0025] The working principle of this utility model is as follows:

[0026] The ultra-high molecular weight polyethylene composite fiber material is placed into the drying cylinder 8 after the square cover 2 is opened. The controller 4 is started, and the servo motor 11 starts working, driving the drive rod 13 and the spiral conveyor blade 14 to rotate. The material is conveyed upward. At the same time, the transmission rod 15, the connecting rod 16, and the scraper 17 rotate with the drive rod 13. The scraper 17 continuously breaks up and turns the accumulated material and scrapes off the material adhering to the drying cylinder 8. At the same time, the hot air heating element 6 is started, and the fan 602 draws in air. After being heated by the air heater 603, the hot air is sent into the drying cylinder 8 through the pipe. The hot air comes into full contact with the material in the drying cylinder 8 to heat and dry the material. At the same time, the infrared heater 7 emits infrared radiation to heat the material. Under the dual action of hot air and infrared radiation, the moisture in the ultra-high molecular weight polyethylene composite fiber material evaporates rapidly, achieving efficient and uniform drying.
