Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber production equipment, in particular to a drying device for recycled polyester material for chemical fiber. Background Art

[0002] Drying equipment for recycled polyester for chemical fibers typically includes a silo, a fluidized bed for crystallization and drying, a dust collector, an intermediate silo, a feeder, a fan, a drying tower, a drying heater, and an air compressor. These components work together to efficiently dry the recycled polyester through processes such as hot air circulation, fluidized bed drying, heating, and ventilation. When designing and operating a drying equipment, factors such as material characteristics, drying temperature, drying time, and air volume must be considered to achieve optimal drying results and production efficiency.

[0003] In the prior art, such as the Chinese patent number: CN217465223U, "Drying device for recycled polyester material for chemical fiber", includes a box body, a fixed cylinder and a controller, the upper surface of the box body is provided with a feed port, the lower surface of the box body is provided with a discharge port, one end of the discharge port is threadedly connected to a sealing plug, one side of the box body is fixedly connected to the controller, the side of the box body close to the controller is hinged with a box door, and the other side of the box door is fixedly connected to the box body by a tower buckle; the utility model turns on the electric heating wire through the controller, dries the raw material by increasing the temperature in the box body, opens the control valve through the controller, and the external high-pressure gas enters the fixed cylinder, which can blow up the raw material in the fixed cylinder and drop it from the fixed cylinder into the box body, and the raw material in the box enters the fixed cylinder again, avoiding uneven drying of the raw material due to the poor fluidity of the recycled polyester raw material for chemical fiber, thereby preventing the quality of the recycled polyester from being affected.

[0004] Although the above scheme has the advantages mentioned above, the disadvantage of the above scheme is that the air inlet pipe is set on the side of the box. This air intake method will make the temperature of the area close to the air inlet pipe high and the temperature of the area farther away low, resulting in uneven temperature distribution inside the box. Uneven temperature distribution will cause the material to dry to different degrees in different areas. Some places may be over-dried, while other places may still be moist, affecting the quality and performance of the final product. At the same time, the geometry and size of the drying chamber, as well as the design of the hot air outlet, may affect the airflow pattern. If the design is improper, such as narrow air ducts, too many bends or uneven outlet distribution, it may lead to a decrease in air flow velocity and promote the formation of laminar flow. Under laminar flow, the movement of steam molecules is relatively orderly, and the contact and heat exchange efficiency with the material surface are low, resulting in a slow drying process and increased energy consumption.

The outer surface of the air collecting box 7 is provided with multiple nozzles 9, the inner surfaces of the multiple nozzles 9 and the two air inlet pipes 6 are movably embedded with plugs 12, the inner surfaces of the multiple plugs 12 are movably embedded with fixing rods 11, and the outer surfaces of the multiple fixing rods 11 are fixedly connected to two fixing blocks 10. A power mechanism is provided on the top of the box body 1, which prevents the formation of a laminar flow state, further improves the uniform distribution of steam inside the box body 1, improves the heat exchange efficiency to a certain extent, shortens the drying time to a certain extent, reduces energy consumption, and ensures product quality and performance.

[0025] like Figure 1-6 As shown, the power mechanism includes multiple support columns 13, multiple support columns 13 are fixedly connected to the top of the box body 1, the tops of the multiple support columns 13 are fixedly connected with support plates 14, the tops of the support plates 14 are fixedly connected with multiple hydraulic cylinders 15, the outer surfaces of the multiple hydraulic cylinders 15 are provided with telescopic rods 16, the multiple telescopic rods 16 are evenly divided into two groups, the bottoms of the two groups of telescopic rods 16 are fixedly connected with pistons 17, the inner surface of the box body 1 is provided with a conveying mechanism 18, the support columns 13 can support the support plate 14, and provide a good working environment for the support plate 14.

[0026] like Figure 1-6 As shown, a controller 19 is fixedly connected to the outer surface of the box body 1 , a display 20 is fixedly connected to the outer surface of the controller 19 , and a plurality of mechanical buttons 21 are fixedly connected to the outer surface of the controller 19 . The mechanical buttons 21 can adjust the working state of the hydraulic cylinder 15 .

[0027] like Figure 1-6As shown, multiple fixing blocks 10 are fixedly connected to the inner and outer surfaces of the two air collecting boxes 7. The fixing blocks 10 can provide support for the fixing rod 11, so that the plug 12 can make a circular motion with the fixing rod 11 as the center.

[0028] like Figure 1-6 As shown, two pistons 17 are movably embedded in the inner surfaces of the two air collecting boxes 7, and multiple telescopic rods 16 are movably embedded in the inner surfaces of the two air collecting boxes 7. The telescopic rods 16 can drive the pistons 17 to rise and fall, thereby changing the pressure in the air collecting boxes 7.

[0029] Working principle: This equipment is a drying device for recycled polyester materials for chemical fibers. When in use, the product to be dried is placed on the conveying mechanism 18, and then the steam is introduced into the air inlet pipe 1 2 and the air inlet pipe 2 6 respectively. The steam in the air inlet pipe 1 2 will first enter the rotating block 4 and then be discharged from the air guide hole 5. When the steam is discharged from the air guide hole 5, it will exert a force on the contour of the air guide hole 5, so that the rotating block 4 drives the ring 3 to rotate. When the rotating block 4 rotates, it diffuses the steam evenly to all parts of the box 1, so that the steam is evenly distributed inside the box 1. Then press the mechanical button 21 on the controller 19 to start the hydraulic cylinder 15, and then monitor the working status of the hydraulic cylinder 15 through the display 20. The hydraulic cylinder 15 causes the telescopic rod 16 to drive the piston 17 to move up and down. When the piston 17 moves upward, the pressure in the air collecting box 7 will be lower than that in the box 1 and the air inlet pipe 2 6 The pressure in the air box 7 will be reduced, and the plug 12 on the air collecting box 7 will be closed, and the steam in the air intake pipe 2 6 will push open the plug 12 in the air intake pipe 2 6, so that the plug 12 in the air intake pipe 2 6 will move in a circular arc with the fixed rod 11 on the fixed block 10 as the center, and thus the steam in the air intake pipe 2 6 will diffuse into the air collecting box 7. When the piston 17 moves downward, the pressure in the air collecting box 7 is greater than the pressure in the box body 1 and the air intake pipe 2 6. At this time, the plug 12 in the air intake pipe 2 6 is closed, and the plug 12 on the air collecting box 7 is opened. At this time, the steam in the air collecting box 7 will be ejected from the nozzle 9. The steam ejected from the nozzle 9 will disrupt the steam flow inside the box body 1, thereby eliminating the generation of laminar flow state and making the steam distribution inside the box body 1 more uniform. The cooperation of the support column 13 and the support plate 14 can provide support for the hydraulic cylinder 15, and the partition 8 can limit the movement trajectory of the piston 17.
