DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] Reference Figure 1-4 , a concrete additive drying device comprises a processing box 1, the side wall of the processing box 1 is connected with a hopper 2, which is convenient for operators to pour the additive to be dried into the processing box 1, and the processing box 1 is provided with an air drying port, and the inner wall of the air drying port is fixedly connected with a fan cover 3. The design of the fan cover 3 is to better guide the airflow, concentrate the wind force, and improve the drying efficiency. The outer wall of the fan cover 3 is fixedly connected with a motor 4, and the motor 4 serves as the main power source of the whole system. The output end of the motor 4 is fixedly connected with a rotating rod 5. The outer wall of the rotating rod 5 located in the fan cover 3 is fixedly connected with multiple sets of fans 6. When the rotating rod 5 rotates, the multiple sets of fans 6 can run at the same time to provide continuous and stable airflow. The rotating rod 5 passes through the fan cover 3 and the side wall of the processing box 1 and is fixedly connected with a rotating disk 7. The rotating disk 7 is connected with a traction rope 12 through a driving linkage mechanism. The traction rope 12 is connected with a filter plate 14. The filter plate 14 is slidably connected to the inner wall of the processing box 1, and an impact mechanism is provided on the top of the processing box 1.

[0019] The linkage mechanism includes a fixed plate 9, which is provided with a sliding groove 10. The inner wall of the sliding groove 10 is slidably connected with a sliding plate 8. The top of the sliding plate 8 is fixedly connected to the end of a traction rope 12. The bottom of the sliding plate 8 is connected to the turntable 7 through a pull rod 11. The sliding plate 8 is fixedly connected to the terminal end of the traction rope 12 to ensure that when the turntable 7 is in operation, the sliding plate 8 suspended under the disc structure can be tightened or loosened synchronously, thereby driving the sliding plate 8 to move back and forth within a set range, thereby driving the lifting action of the filter plate 14.

[0020] The outer walls of the turntable 7 and the sliding plate 8 are fixedly connected with a linkage shaft, and linkage ports are opened at both ends of the pull rod 11. The material of the pull rod 11 has a certain strength and toughness to withstand long-term tensile and compressive stresses to ensure stable operation during long-term operation. The inner walls of the two linkage ports are rotatably sleeved with the outer walls of the linkage shaft. The linkage shafts on the turntable 7 and the sliding plate 8 should be precisely processed to ensure good cooperation with the linkage ports of the pull rod 11 to avoid inaccurate movement due to excessive clearance.

[0021] Two guide plates 13 are fixedly connected to the top of the processing box 1. The guide plates 13 play the role of guiding and supporting the movement path of the traction rope 12, preventing the traction rope 12 from deviating from the correct track during movement, and ensuring the stability and reliability of the system. A traction port is provided on the top of the processing box 1. The traction rope 12 passes around the guide plate 13 and the traction port in turn, ensuring that the traction rope 12 can be introduced from the outside into the processing box 1, and connected to the filter plate 14 in the processing box 1 through the traction device.

[0022] The impact mechanism includes a plurality of telescopic rods 15 fixedly connected to the top of the processing box 1, and an impact head 16 fixedly connected to the bottom of the telescopic rods 15. These telescopic rods 15 are evenly distributed along the longitudinal direction of the processing box 1 to ensure that the entire device can provide uniform and controllable impact force during operation.

[0023] The outer wall of the telescopic rod 15 is sleeved with a telescopic spring 17, and the two ends of the telescopic spring 17 are fixedly connected to the top of the processing box 1 and the outer wall of the impact head 16 respectively. By adjusting the elastic force of the telescopic spring 17, the movement state of the filter plate 14 can be further optimized.

[0024] A plurality of groups of electric heating wires 18 are fixedly connected to the inner wall of the processing box 1 located at the air-drying port. The electric heating wires 18 are heating components to accelerate the evaporation of moisture in the additive. The electric heating wires 18 are installed inside the processing box 1 near the air-drying port and are evenly distributed on its side walls so that the air flow passing through the air-drying port can fully contact the electric heating wires 18, thereby increasing the air temperature.

[0025] The specific working principle of the present invention is as follows: In the initial state, during the actual operation, the concrete additive to be dried is first added from the feed hopper 2 into the processing box 1. After the motor 4 is started, the output end of the motor 4 drives the rotating rod 5 to rotate, thereby driving the multiple sets of fans 6 to rotate at high speed, thereby forming a strong airflow, which is evenly blown to the inside of the processing box 1 through the fan cover 3, effectively accelerating the evaporation of water in the concrete additive. At the same time, the other end of the rotating rod 5 is fixedly connected to a turntable 7. When the turntable 7 rotates, the linkage shaft thereon rotates accordingly. Since the linkage port of the pull rod 11 is connected to the linkage shaft through a rotating sleeve, the pull rod 11 can move with the linkage shaft during the rotation of the turntable 7, thereby pushing or pulling the sliding plate 8 to move up and down. The sliding plate 8 generates a periodic rotation by the traction rope 12 The filter plate 14 moves upwards and is impacted by the impact mechanism. The filter plate 14 slides along the side wall inside the processing box 1, which not only increases the contact area between the concrete additive and the airflow, but also causes the additive particles to tumble and stir continuously, ensuring that each part can be fully affected by the hot air, thereby improving the drying efficiency. The impact mechanism arranged on the top of the processing box 1 further enhances this process, and by generating slight vibration or impact force, the additive attached to the filter plate 14 can fall off in time to avoid clogging the filter plate 14 and further disperse the material. Finally, the fully dried concrete additive can be collected from the discharge port at the bottom of the processing box 1 to complete the entire drying process.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
