[0002] The treatment and recycling of granular spent activated carbon is receiving increasing attention in many fields such as chemical engineering and environmental protection. However, drying is currently a challenge in the treatment of granular spent activated carbon.

[0003] Existing conveying equipment is only focused on transporting waste activated carbon from one place to another and has no drying function at all. This means that waste activated carbon must be treated with special drying equipment before transportation. Currently, large drying boxes are used to dry waste activated carbon, and after drying, ordinary conveyors are used for transfer. This separate operation process is cumbersome, which not only increases labor and time costs, but also results in extremely low drying efficiency.

[0004] In addition, traditional drying equipment has many drawbacks when processing granular waste activated carbon. Some drying equipment cannot achieve uniform drying, and it is easy to have local over-drying or under-drying, which affects the subsequent utilization value of waste activated carbon.

[0035] like Figures 1-4 As shown, it illustrates an atmospheric pressure screw conveyor for granular waste activated carbon according to an embodiment of this disclosure, comprising:

[0036] Material bin 1 and conveying pipe 2, with conveying pipe 2 located at the bottom of material bin 1;

[0037] Connecting adjustment component 5, which is located between material box 1 and conveying pipe 2;

[0038] The conveying auger 3 and the drying assembly 4 are installed inside the conveying pipe 2, and the drying assembly 4 is located inside the hopper 1 and the conveying pipe 2.

[0039] The drying assembly 4 includes a hot air blower 4-1, which is mounted on the side surface of the material box 1. Air chamber frames 4-2 are movably fitted onto both sides of the material box 1. Air chamber frames 4-2 have air outlets 4-3 on their upper and lower surfaces and are connected to the output end of the hot air blower 4-1. Fixed frames 4-4 are mounted on both sides of the material box 1, and a drive shaft 4-5 is rotatably connected between the fixed frames 4-4. The drive shaft 4-5 is rotated by a motor, and both ends of the drive shaft 4-5 have external threads. 4-6 and the air chamber frame 4-2 are connected to the external thread layer 4-6 by threaded engagement. An air hood 4-7 is provided on the surface of the conveying pipe 2. An air inlet 4-8 is provided at the top of the conveying pipe 2. The air inlet 4-8 is connected to the air hood 4-7. The air hood 4-7 is connected to the output end of the hot air blower 4-1. A discharge port 4-9 is provided at one end of the conveying pipe 2. A cavity 4-10 is provided inside the conveying auger 3. A heating pipe 4-11 is provided on the inner surface of the conveying pipe 2. The heating pipe 4-11 is located inside the cavity 4-10.

[0040] In some examples, to achieve thorough drying of waste activated carbon, a drying assembly 4 is designed, including a hot air blower 4-1 fixed to one side of the material box 1 to provide hot air. An air chamber frame 4-2 has multiple branches and is movably connected to the material box 1. The air chamber frame 4-2 is slidable and connected to the output end of the hot air blower 4-1 to receive hot air, which is dispersed upwards and downwards into the waste activated carbon in the material box 1 through the air inlet 4-8. A fixed frame 4-4 is fixed to both sides of the material box 1. A drive shaft 4-5 with external thread layers 4-6 at both ends is rotatably connected between the fixed frames 4-4 and rotated by a motor. The air chamber frame 4-2 is connected to the external thread layers 4-6 via a threaded engagement. 5. When rotating, the air chamber frame 4-2 can be controlled to move repeatedly, so that the air chamber frame 4-2 moves repeatedly within the waste activated carbon particles while spraying hot air, fully diffusing the hot air and enhancing the drying effect. The air hood 4-7 is connected to the top of the conveying pipe 2. The air hood 4-7 is connected to the conveying pipe 2 through the air inlet 4-8. The air hood 4-7 is connected to the output end of the hot air blower 4-1, which can blow some hot air into the conveying pipe 2. The front end of the conveying pipe 2 has a discharge port 4-9 for discharging the material. A cavity 4-10 is also opened in the shaft of the conveying auger 3. A heating tube 4-11 is set on the inner surface of the conveying pipe 2 and located in the cavity 4-10, which can heat the conveying auger 3 and transfer the heat to the waste activated carbon being conveyed.

[0041] like Figures 1-4As shown, this embodiment proposes a connecting adjustment component 5 including a telescopic pipe 5-1, which is connected between the bottom of the material box 1 and the conveying pipe 2. A pair of connecting frames 5-2 are provided at the bottom of the material box 1. The conveying pipe 2 is rotatably connected to the connecting frames 5-2 by a pin. Connecting frames 5-3 are provided on both the side surface of the material box 1 and the surface of the conveying pipe 2. A hydraulic cylinder 5-4 is rotatably connected between the connecting frames 5-3 by a pin.

[0042] In some examples, to achieve an adjustable conveying angle, a connecting adjustment component 5 is designed, including a telescopic pipe 5-1 connected between the hopper 1 and the conveying pipe 2. The conveying pipe 2 is rotatably connected to the bottom of the hopper 1 via a connecting frame 5-2 pin. A connecting frame 5-3 is fixed to the outer surface of the hopper 1, connecting the connecting frame 5-2 and the conveying pipe 2. A hydraulic cylinder 5-4 is connected between the two connecting frames 5-3. By retracting the output end of the hydraulic cylinder 5-4, the conveying pipe 2 can be pulled upward and lifted.

[0043] For example, such as Figure 2 As shown, a support frame 6 is fixed at the bottom of the material box 1, and the bottom of the support frame 6 on one side has a semi-circular structure.

[0044] In some examples, the support frame 6 is provided to increase the stability of the material box 1 on the ground and to accommodate the angle changes produced by the conveying pipe 2.

[0045] For example, such as Figure 1 As shown, the conveying pipe 2 can be rotated upwards by 45°-60° under the control of hydraulic cylinders 5-4.

[0046] In some examples, a tilt angle of 45°-60° can be used to adjust the feed height of the processing equipment.

[0047] For example, such as Figure 3 As shown, the external thread layers 4-6 located at both ends of the drive shaft 4-5 have opposite thread directions.

[0048] In some examples, by using opposite thread directions, the two air chamber frames 4-2 can be controlled to move synchronously inward or outward.

[0049] For example, such as Figure 4 As shown, the conveying auger 3 adopts a thermally conductive material structure.

[0050] In some examples, the heat-conducting material structure enables the conveying auger 3 to transfer the heat from the heating tubes 4-11 to the waste activated carbon particles in contact with the outer surface.

[0051] In actual use: Pour granular waste activated carbon into the material box 1, start the hot air blower 4-1, and the hot air blower 4-1 delivers hot air to the air chamber frame 4-2. The air outlets 4-3 on the upper and lower surfaces of the air chamber frame 4-2 spray the hot air into the waste activated carbon in the material box 1. At the same time, start the motor that controls the drive shaft 4-5. The drive shaft 4-5 rotates, causing the air chamber frames 4-2 at both ends to move repeatedly within the surfaces on both sides of the material box 1, so that the hot air is evenly diffused and the drying effect is enhanced. Some of the hot air enters the conveying pipe through the air hood 4-7 and the air inlet 4-8. 2. The waste activated carbon in the pipeline is preheated. The conveying auger 3 rotates under the drive of the motor, and the dried waste activated carbon is transported from the material box 1 through the conveying pipeline 2 to the discharge port 4-9. During this process, the heating pipe 4-11 on the inner surface of the conveying pipeline 2 heats the conveying auger 3. The heat is transferred to the waste activated carbon through the heat-conducting material of the conveying auger 3 for further drying. The angle of the conveying pipeline 2 can be adjusted by the hydraulic cylinder 5-4 according to actual needs, and the telescopic pipeline 5-1 adapts to the angle change to ensure smooth conveying.
