Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and in particular to an impeller feeding device for a rotary drum dryer. Background Technology

[0002] The main body of a rotary drum dryer is a rotatable cylindrical drum. The material enters from one end of the drum and, as the drum rotates, the material tumbles inside, making full contact with the hot airflow entering from the other end. Heat is transferred through heat conduction, convection, and radiation, causing the moisture in the material to evaporate and be carried away by the hot airflow, thereby achieving the drying of the material.

[0003] Existing rotary drum dryers typically use hot air heating, employing electric heating devices to generate hot air. The hot air enters the drum and comes into full contact with the material, transferring heat through convection to evaporate the moisture in the material. However, they lack the function of breaking up the material during drying. This results in the clumps of material having difficulty coming into full contact with the hot air, causing the external moisture to evaporate faster while the internal moisture is difficult to expel. Consequently, the material is dried unevenly, affecting product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an impeller feeding device for a rotary drum dryer, which aims to improve the problem that existing rotary drum dryers do not have the function of breaking up materials during drying, resulting in uneven drying of materials and affecting product quality.

The upper part of the housing 7 is fixedly connected to the outer wall of the feed hopper 9. The bottom of the housing 7 is provided with a cleaning port 13. The outer wall of the housing 7 is fixedly connected to a combustion chamber 8.

[0026] Specifically, the material is first poured into the feed hopper 9, and then the drum dryer body 1 is turned on to perform circular motion. When the drum dryer body 1 performs circular motion, it will drive the impeller body 6 to rotate. When the impeller body 6 rotates, it will drive several square plates on the inner wall to rotate. Through the cooperation between the impeller body 6 and the several square plates on the inner wall of the impeller body 6, the material is dispersed, so that the material can fully contact the hot air, thereby improving the working efficiency of the drum dryer body 1.

[0027] Reference Figures 2-4 The impeller body 6 is composed of two circular ring plates and several square plates; the outer shell 7 is composed of a first semi-circular sealing plate 10, a second semi-circular sealing plate 11 and a cylindrical rear shell 12.

[0028] Specifically, the square plate is used to break up the material so that it can fully contact the hot air.

[0029] Reference Figure 1 and Figure 5 A support frame 14 is fixedly connected to the outer wall of the feed hopper 9. A motor 15 is fixedly connected to the inner wall of the support frame 14. A transmission assembly is provided at the output end of the motor 15. A stirring blade 17 is fixedly connected to the outer wall of the transmission assembly. A transmission belt 19 is provided on the outer wall of the transmission assembly. A stirring assembly is provided on the outer wall of the transmission belt 19. A third rotating wheel 21 is provided on the outer wall of the transmission belt 19. A first stirring rod 22 is fixedly connected to the inner wall of the third rotating wheel 21. The transmission assembly includes a transmission column 16. The output end of the motor 15 is connected to the outer wall of the transmission column 16. A third stirring rod 22 is fixedly connected to the outer wall of the transmission column 16. The first rotating wheel 18 has its outer wall rotatably connected to the inner wall of the feed hopper 9, and the outer wall of the stirring blade 17 is fixedly connected to the outer wall of the transmission column 16. The outer wall of the transmission belt 19 is disposed on the outer wall of the first rotating wheel 18. The stirring assembly includes a second rotating wheel 20, the outer wall of the transmission belt 19 is disposed on the outer wall of the second rotating wheel 20, and a second stirring rod 23 is fixedly connected to the inner wall of the second rotating wheel 20. The outer wall of the stirring blade 17 is fixedly connected to the outer walls of the first stirring rod 22 and the second stirring rod 23. The outer walls of both the first stirring rod 22 and the second stirring rod 23 are rotatably connected to the inner wall of the feed hopper 9.

[0030] Specifically, the motor 15 is first turned on to drive the transmission column 16 to rotate. Through the fixed action of the transmission column 16 and the first rotating wheel 18, the first rotating wheel 18 will be driven to rotate, which in turn drives the transmission belt 19 to rotate. When the transmission belt 19 rotates, it will drive the second rotating wheel 20 and the third rotating wheel 21 to rotate. Through the fixed action of the second rotating wheel 20 and the third rotating wheel 21 with the second stirring rod 23 and the first stirring rod 22, the first stirring rod 22 and the second stirring rod 23 will be driven to rotate. Since the stirring plate 17 is fixedly connected to the transmission column 16, the first stirring rod 22 and the second stirring rod 23, the rotation of the transmission column 16, the first stirring rod 22 and the second stirring rod 23 will drive the stirring plate 17 to rotate, thereby achieving the effect of stirring the material inside the feed hopper 9 and avoiding the accumulation of material which affects the normal operation of the equipment.

[0031] Working principle: First, pour the material to be dried into the feed hopper 9, then turn on the drum dryer body 1, causing the drum dryer body 1 to move in a circular motion. When the drum dryer body 1 moves in a circular motion, it will drive the impeller body 6 to rotate. When the impeller body 6 rotates, it will drive the pusher plate 5 and the square plate on the inner wall of the impeller body 6 to rotate synchronously. In this way, when conveying materials, the rotation of the square plate will break up the materials, allowing the materials to fully contact the hot air, thereby improving the working efficiency of the drum dryer body 1 and greatly saving fuel.

[0032] The starter motor 15 drives the transmission column 16 to rotate on the inner wall of the feed hopper 9, which in turn drives the first rotating wheel 18 to rotate. When the first rotating wheel 18 rotates, it drives the transmission belt 19 to rotate. When the transmission belt 19 rotates, it drives the second rotating wheel 20 and the third rotating wheel 21 to rotate, which in turn drives the first stirring rod 22 and the second stirring rod 23 to rotate. Through the fixed connection between the stirring plate 17 and the transmission column 16, the first stirring rod 22, and the second stirring rod 23, the material in the feed hopper 9 is fully stirred, thus avoiding the accumulation of material.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
