The feeding device of a fluidized bed dryer is the part of the equipment used to transfer the material to be dried into the dryer.
[0003] Existing fluidized bed dryer feeding devices only transfer granular materials into the fluidized bed dryer. However, during the storage and transportation of granular materials, the materials are affected by accumulation and compression, which changes the size and shape of the granular materials. When granular materials of different sizes and shapes enter the fluidized bed dryer, it will lead to uneven drying of the materials. Therefore, a new type of fluidized bed dryer feeding device is needed. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a technical solution: a feeding device for a fluidized bed dryer, comprising a base plate 1, two support plates 2 fixedly connected to the top of the base plate 1, a screw feeder 3 fixedly connected between the tops of the two support plates 2, a screen body 4 fixedly connected to one end of the outer surface of the screw feeder 3, a first sliding groove 5 provided on the relative inner walls of the screen body 4, a movable plate 6 slidably connected between the relative inner walls of the two first sliding grooves 5, a plurality of evenly arranged round holes 7 provided on the outer surface of the movable plate 6, a second sliding groove 8 provided on one side of the outer surface of the screen body 4, a slider 9 slidably connected to the inner wall of the second sliding groove 8, a first moving strip 10 rotatably connected to one end of the outer surface of the slider 9, a limit block 11 slidably connected to the inner wall of the first moving strip 10, and a first gear 12 fixedly connected to one side of the outer surface of the limit block 11.
[0023] like Figure 2-3As shown, the outer surface of the slider 9 is fixedly connected to one side of the outer surface of the moving plate 6. The inner wall of the first gear 12 is rotatably connected to the rotating shaft 13. One side of the outer surface of the rotating shaft 13 is fixedly connected to one end of the screw feeder 3. The rotating shaft 13 can limit and connect the first gear 12.
[0024] like Figure 1-4 As shown, a first motor 15 is provided on one outer surface of the base plate 1. The output end of the first motor 15 is fixedly connected to an output shaft 16. One end of the output shaft 16 movably passes through the outer surface of the screw feeder 3 and extends into the interior. A second gear 14 is fixedly sleeved on the outer surface of the output shaft 16. By providing the second gear 14, the output shaft 16 can drive the second gear 14 to rotate when it rotates.
[0025] like Figure 2-4 As shown, the outer surface of the first gear 12 meshes with the outer surface of the second gear 14. The top of the screen body 4 is fixedly connected to the crusher 17, and the top of the crusher 17 is fixedly connected to the collection box 18. A second motor 19 is provided on one side of the outer surface of the crusher 17. Through the meshing of the first gear 12 and the second gear 14, the second gear 14 can drive the first gear 12 to rotate when it rotates.
[0026] like Figure 3-4 As shown, two fixing blocks 20 are fixedly connected to one side of the outer surface of the screen body 4. The inner walls of the two fixing blocks 20 are slidably connected to the second moving strips 21. The outer surfaces of the two second moving strips 21 are in contact with the outer surface of the first moving strip 10. The fixing blocks 20 are used to limit and support the second moving strips 21.
[0027] like Figure 3-4 As shown, a fixed plate 22 is fixedly connected to the outer surface of the screen body 4 near the two side edges. A slide rail 23 is fixedly connected to the outer surface of the two fixed plates 22. The inner wall of the two slide rails 23 slides against the outer surface of the two second moving bars 21 respectively. By setting the slide rails 23, the second moving bars 21 can slide within the slide rails 23.
[0028] like Figure 3-4 As shown, the feature is that: springs 24 are provided on the outer surfaces of the two fixed plates 22 respectively, one end of the two springs 24 is fixedly connected to the outer surfaces of the two fixed plates 22 respectively, and the other end of the two springs 24 is fixedly connected to the outer surfaces of the two second moving bars 21 respectively. By providing springs 24, the second moving bars 21 can be kept in contact with the first moving bar 10.
[0029] The operating method and working principle of this device are as follows: When using the feeding device for a fluidized bed dryer, the operator needs to start the first motor 15 and the second motor 19, and then pour the granular material to be dried into the collection box 18. The material will move downwards along the inside of the collection box 18 and fall into the crusher 17. The second motor 19 will rotate the fan blades in the crusher 17 to crush the material. The crushed material will fall downwards into the screen body 4. At the same time, when the first motor 15 rotates, it will drive the output shaft 16 to rotate. The rotation of the output shaft 16 will drive the second gear 14 on the outer surface of the output shaft 16. When the second gear 14 rotates, it drives the first gear 12, which meshes with the outer surface of the second gear 14, to rotate. The first gear 12 rotates along the outer surface of the shaft 13. When the first gear 12 rotates, it drives the limiting block 11 to rotate. When the limiting block 11 rotates, it slides on the inner wall of the first moving strip 10 and also drives the first moving strip 10 to move. When the first moving strip 10 moves, it pushes the second moving strips 21 on both sides to move. The second moving strips 21 slide on the inner wall of the fixed block 20. One end of one of the second moving strips 21 slides along the inner wall of the slide rail 23 and compresses the spring 24. One end of a second moving bar 21 slides along the inner wall of the slide rail 23, stretching the spring 24. Simultaneously, as the first moving bar 10 moves, it drives the slider 9 to slide along the inner wall of the second slide groove 8. The slider 9 also drives the moving plate 6 to slide along the inside of the first slide groove 5. As the moving plate 6 moves, multiple evenly arranged circular holes 7 also move, causing material to fall into the moving plate 6. The moving plate 6, by moving, drives the multiple circular holes 7 to move, allowing material of the required drying size to fall through the holes 7 into the screw conveyor 3. At the same time, the output shaft 16 of the first motor 15 drives the screw conveyor 3. The rotating blades transport the granular material falling into the screw feeder 3 to the fluidized bed dryer. Larger granular materials cannot fall into the screw feeder 3 through the multiple round holes 7. The larger granular materials will be intercepted on the moving plate 6. The staff can collect them and crush them again with other granular materials until the granular materials can fall into the screw feeder 3 through the round holes 7. The screw feeder 3 transports the granular materials into the fluidized bed dryer, thus ensuring that the granular materials entering the fluidized bed dryer are of similar size and shape, improving the uniformity of material drying in the fluidized bed dryer.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
