Description

Technical Field

[0001] This utility model relates to the field of additive drying technology, and in particular to a concrete additive drying device. Background Technology

[0002] Chemical substances added during the mixing process to improve the performance of concrete are called concrete chemical admixtures. Concrete additive drying equipment is mainly used to process and dry various additives in concrete to ensure that their moisture is effectively removed before use.

[0003] However, this device has two main problems: First, uneven distribution of the additives in the drying chamber can lead to localized overheating or insufficient drying, thus affecting the quality of the final product; second, concrete additives tend to accumulate dust inside the filter screen, increasing cleaning difficulty and potentially causing filter clogging, which in turn affects the feeding speed and production efficiency. These problems urgently need to be addressed in practical applications. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

[0023] Reference Figure 1-4 A concrete additive drying device includes a processing box 1. A hopper 2 is connected to the side wall of the processing box 1, allowing operators to easily pour the additive to be dried into the processing box 1. The processing box 1 is equipped with a drying inlet. A fan cover 3 is fixedly connected to the inner wall of the drying inlet. The fan cover 3 is designed to better guide airflow, concentrate airflow, and improve drying efficiency. A motor 4 is fixedly connected to the outer wall of the fan cover 3. The motor 4 serves as the main power source for the entire system. A rotating rod 5 is fixedly connected to the output end of the motor 4. Multiple sets of fans 6 are fixedly connected to the outer wall of the rotating rod 5, which is located inside the fan cover 3. When the rotating rod 5 rotates, the multiple sets of fans 6 can operate simultaneously, providing a 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 to a turntable 7. The turntable 7 is connected to a traction rope 12 via a linkage mechanism. The traction rope 12 is connected to a filter plate 14. The filter plate 14 is slidably connected to the inner wall of the processing box 1. An impact mechanism is provided at the top of the processing box 1.

[0024] The linkage mechanism includes a fixed plate 9, on which a sliding groove 10 is provided. A sliding plate 8 is slidably connected to the inner wall of the sliding groove 10. The top of the sliding plate 8 is fixedly connected to the end of the traction rope 12, and 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 end of the traction rope 12, ensuring that when the turntable 7 operates, the sliding plate 8 suspended below the disc structure can be tightened or loosened synchronously, thereby driving the sliding plate 8 to move back and forth within a set range, and thus driving the lifting and lowering action of the filter plate 14.

[0025] Both the outer wall of the turntable 7 and the outer wall of the sliding plate 8 are fixedly connected to a linkage shaft. Both ends of the pull rod 11 are provided with linkage ports. The material of the pull rod 11 has a certain strength and toughness to withstand long-term tensile and compressive stress, ensuring 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 machined to ensure good fit with the linkage ports of the pull rod 11, avoiding inaccurate movement due to excessive clearance.

[0026] Two guide plates 13 are fixedly connected to the top of the treatment box 1. The guide plates 13 serve to guide and support the movement path of the traction rope 12, preventing the traction rope 12 from deviating from the correct trajectory during movement, and ensuring the stability and reliability of the system. The top of the treatment box 1 is provided with a traction port. The traction rope 12 passes through the guide plates 13 and the traction port in sequence, ensuring that the traction rope 12 can be introduced into the interior of the treatment box 1 from the outside and connected to the filter plate 14 inside the treatment box 1 through the traction device.

[0027] The impact mechanism includes multiple telescopic rods 15 fixedly connected to the top of the processing box 1. Impact heads 16 are 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 a uniform and controllable impact force during operation.

[0028] A telescopic spring 17 is fitted on the outer wall of the telescopic rod 15. The two ends of the telescopic spring 17 are fixedly connected to the top of the treatment 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.

[0029] Multiple sets of heating wires 18 are fixedly connected to the inner wall of the processing box 1 located at the air drying port. The heating wires 18 are heating components to accelerate the evaporation of moisture from the additives. The heating wires 18 are installed inside the processing box 1 near the air drying port and are evenly distributed on its side wall so that the airflow passing through the air drying port can fully contact the heating wires 18, thereby increasing the air temperature.

[0030] The specific working principle of this utility model is as follows:

[0031] In the initial state, during actual operation, the concrete additive to be dried is first added from the feed hopper 2 into the processing box 1. After starting the motor 4, the output end of the motor 4 drives the rotating rod 5 to rotate, which in turn drives multiple sets of fans 6 to rotate at high speed, thereby forming a strong airflow. This airflow is evenly blown into the processing box 1 through the fan cover 3, effectively accelerating the evaporation of moisture in the concrete additive. At the same time, a turntable 7 is fixedly connected to the other end of the rotating rod 5. When the turntable 7 rotates, the linkage shaft on it 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 causes the traction rope 12 to generate periodic motion. The tension and relaxation of the airflow causes the filter plate 14 to move up and down. When the filter plate 14 moves upward, it 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 is fully affected by the hot air and improving the drying efficiency. The impact mechanism set at the top of the processing box 1 further enhances this process. By generating slight vibration or impact, the additive attached to the filter plate 14 can be detached in time, avoiding clogging of the filter plate 14 and further dispersing the material. Finally, the fully dried concrete additive can be collected from the discharge port at the bottom of the processing box 1, completing the entire drying process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
