[0002] Nylon is a type of synthetic polymer and a type of synthetic fiber. It is usually composed of polyamide compounds and is widely used in textiles, industrial products, plastic products and other fields. The raw materials for the production of nylon usually include polyamide precursors, such as polycaprolactam, polyether lactam, etc. The synthesis of these polyamide precursors involves polymerization reactions, in which water needs to be removed during the reaction, so a raw material dehydration device for nylon production is required.

[0003] In an existing raw material dehydration device for nylon production, when in use, a hot air blower is provided to blow hot air into a drying box through an air inlet pipe, and an exhaust fan is provided to discharge water vapor, thereby accelerating the drying efficiency.

Such uneven distribution will affect the quality and performance of the final product, and the dehydration device will take longer to ensure that all parts are fully dried, which will increase the production cycle and reduce production efficiency.

[0024] The drying box 1 fixes the pad 2. The main function of the pad 2 is to provide support and fix the motor 3. It ensures that the motor 3 can be firmly mounted on the equipment so as to transmit power to other components. The output end of the motor 3 drives the support rod 4 to rotate. The rotation of the support rod 4 drives the fixed plate 6 to rotate at the same time. The rotation of the fixed plate 6 drives the connecting rod 7 to rotate. The rotation of the connecting rod 7 drives the pulley 8 to slide inside the slide rail 9. The slide rail 9 plays a limiting role. Under the action of the pulley 8, the support rod 4 drives the drying drum 5 to rotate.

[0025] Reference Figure 2 and Figure 3 A filter plate 21 is fixedly connected to the interior of the drying box 1, and the filter plate 21 is arranged at the lower part of the drying drum 5. A feed pipe 12 is arranged on the right part of the drying box 1, and the feed pipe 12 is inserted into the interior of the drying drum 5. A feed hopper 13 is fixedly connected to the upper part of the feed pipe 12. A discharge hopper 22 is arranged on the right part of the drying box 1. The drying drum 5 is rotatably connected to the interior of the drying box 1. Installation boxes 10 are fixedly connected to both sides of the inner top of the drying box 1, and an electric heating rod 11 is fixedly connected to the interior of the installation box 10. Support legs 23 are fixedly connected to both sides of the bottom of the drying box 1. A water outlet pipe 24 is arranged at the bottom of the drying box 1, and a control valve 25 is arranged outside the water outlet pipe 24.

[0026] A filter plate 21 is provided, which can filter steam and raw materials. The control valve 25 is opened so that the steam can be discharged through the water outlet pipe 24. Under the action of the filter plate 21, the raw materials can be discharged through the discharge hopper 22, and the raw materials are poured into the inside of the feed hopper 13. The raw materials are transported to the inside of the drying drum 5 through the feed pipe 12. The feed pipe 12 is inserted into the inside of the drying drum 5 so that the drying drum 5 can rotate outside the feed pipe 12. The mounting box 10 fixes the electric heating rod 11. The two groups of electric heating rods 11 are electrically connected to the external power supply to heat the inside of the drying box 1. Support legs 23 are provided to improve the stability of the device.

[0027] Reference Figure 2-Figure 4 A fixed box 14 is fixedly connected to the upper part of the drying box 1, a cylinder 15 is fixedly connected inside the fixed box 14, a mounting plate 16 is fixedly connected to the output end of the cylinder 15, a cleaning brush 17 is arranged at the bottom of the mounting plate 16, fixed rods 18 are fixedly connected to both sides of the interior of the fixed box 14, a moving rod 20 is slidably connected inside the fixed rod 18, the bottom of the moving rod 20 is fixedly connected to the mounting plate 16, a spring 19 is arranged inside the fixed rod 18, one end of the spring 19 is fixedly connected to the inside of the fixed rod 18, and the other end of the spring 19 is fixedly connected to the upper part of the moving rod 20, a through groove is opened inside the drying box 1, and the mounting plate 16 and the cleaning brush 17 are both slidably connected inside the through groove.

[0028] The drying box 1 fixes the fixed box 14, and the fixed box 14 fixes the cylinder 15. The cylinder 15 pushes the mounting plate 16 to move. The movement of the mounting plate 16 drives the cleaning brush 17 to move downward. The movement of the mounting plate 16 drives the moving rod 20 to move. The movement of the moving rod 20 drives the spring 19 to stretch. The spring 19 plays a certain buffering role. When the mounting plate 16 drives the moving rod 20 to retract, the moving rod 20 squeezes the spring 19, so that the mounting plate 16 drives the cleaning brush 17 to retract upward through the through groove. Under the action of the moving rod 20, the stability of the mounting plate 16 when moving is improved.

[0029] Working principle: First, the raw materials are added into the interior of the drying drum 5 through the feed hopper 13 and the feed pipe 12, and the motor 3 is started at the same time. The output end of the motor 3 drives the support rod 4 to rotate, and the support rod 4 drives the drying drum 5 to rotate, so that the drying drum 5 drives the raw materials inside to rotate. Under the action of the electric heating rod 11, the raw materials are dehydrated, thereby helping the raw materials to be more evenly exposed to the dehydration environment, ensuring that the moisture evaporates more evenly from the raw materials, increasing the contact surface area between the raw materials and the heat source, and improving the heat conduction efficiency, which helps to improve the efficiency of the dehydration process and reduce the production cycle. When the drying drum 5 is used up, the cylinder 15 is started, and the cylinder 15 pushes the mounting plate 16 to move downward, and the mounting plate 16 drives the cleaning brush 17 to move downward, so that the cleaning brush 17 contacts the surface of the drying drum 5, and the motor 3 is started again to rotate the drying drum 5. Under the action of the cleaning brush 17, the surface of the drying drum 5 is cleaned, thereby effectively cleaning the drying drum 5, which can effectively prevent the accumulation of pollutants, avoid cross contamination between different raw materials, ensure the purity of the raw materials, and extend the service life of the equipment.
