Description

Technical Field

[0001] This utility model relates to the field of material drying, specifically a mobile feeding device for a fluidized bed dryer. Background Technology

[0002] Fluidized bed dryers are equipment used for drying materials. Due to their fast drying speed, low temperature, ability to ensure product quality, and compliance with GMP requirements for pharmaceutical production, they are widely used in the pharmaceutical, chemical, and food industries. In operation, a trolley is used to move the hopper between the dryer's base and the expansion cylinder. Hot air is then introduced through the air inlet pipe on the base, passing through the perforated plate at the bottom of the hopper and entering the hopper. The air expands within the expansion cylinder, causing the material to boil, significantly improving drying efficiency. After drying, the trolley moves the hopper out to remove the dried material. However, in actual use, moving the hopper with the trolley requires constant adjustment to align its top and bottom with the expansion cylinder and base, affecting the efficiency and convenience of feeding. Furthermore, removing material from the hopper requires manually rotating it and keeping it tilted, making the process inconvenient. Therefore, the feeding device of existing fluidized bed dryers needs further optimization in terms of the convenience of feeding and removing materials. Utility Model Content

[0003] The purpose of this utility model is to provide a mobile feeding device for a fluidized bed dryer, which can solve the technical problems of slow feeding and inconvenient material removal in existing fluidized bed dryer feeding devices. It enables the hopper to quickly align with the base and expansion cylinder, improving feeding efficiency. When removing material, the hopper can be tilted and maintained at a specified angle, greatly improving the convenience of material removal.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A mobile feeding device for a fluidized bed dryer includes a hopper disposed between a base and an expansion cylinder. A fixed frame is provided between the base and the expansion cylinder. A movable frame is provided on the hopper. The bottom of the movable frame is provided with multiple movable wheels. The two sides of the hopper are rotatably connected to the movable frame. A guide frame is provided on the movable frame. The guide frame is provided with guide holes. A guide post is provided on the hopper. The guide post is slidably connected in the guide holes. A limiting component is provided on the guide post to cooperate with the guide frame. Extension rods are symmetrically provided on both sides of the bottom of the movable frame. Track grooves for cooperating with the extension rods are symmetrically provided on both sides of the fixed frame. A positioning post is provided in the track groove. A positioning groove for cooperating with the positioning post is provided on the extension rod. When the positioning post moves to one end of the positioning groove, the upper and lower ends of the hopper are aligned with the expansion cylinder and the base, respectively.

[0005] Furthermore, the limiting component includes limiting holes and limiting posts. The limiting holes are symmetrically arranged on the guide frame, and a sliding post is slidably connected to the guide post. The limiting posts are symmetrically arranged on the sliding post, and the limiting posts are movably inserted into the limiting holes.

[0006] Furthermore, the guide post is provided with a sliding hole, the slide post is slidably connected in the sliding hole, and a compression spring is provided between the end of the slide post and the end of the sliding hole.

[0007] Furthermore, the sliding column is provided with a protruding plate, which is slidably connected to the sliding hole. The end of the sliding hole is provided with a locking edge, and the sliding column passes through the locking edge and is slidably connected to it. The compression spring is disposed between the protruding plate and the locking edge.

[0008] Furthermore, the guide hole is arc-shaped, and the limiting holes are arranged in a circular array on the side of the guide hole.

[0009] Furthermore, the ends of the track groove are symmetrically provided with arc-shaped transition plates for use with extension rods.

[0010] Furthermore, a guide wheel is rotatably connected to the arc-shaped transition plate, and the guide wheel makes rolling contact with the extension rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model sets the hopper on a movable frame. The bottom of the movable frame is equipped with movable wheels, and the movable frame is equipped with a guide frame with a guide hole. The guide column on the hopper is slidably connected in the guide hole, and the guide column is equipped with a limiting component that works with the guide frame. With this structure, when removing material from the hopper, it is only necessary to rotate the hopper to drive the guide column to slide in the guide hole. After rotating to the correct position, the limiting component is used to fix the relative position of the guide column and the guide frame, thereby maintaining the tilted state of the hopper. This makes it easier to remove the material from the hopper without the need for manual handling of the hopper, greatly reducing the workload of material removal and improving the convenience and efficiency of material removal. 2. Symmetrical extension rods are installed on both sides of the bottom of the mobile frame. Symmetrical track grooves for the extension rods are provided on both sides of the fixed frame. Positioning posts are installed within the track grooves, and positioning grooves for the positioning posts are provided on the extension rods. When the positioning post moves to one end of the positioning groove, the upper and lower ends of the hopper are aligned with the expansion cylinder and the base, respectively. This structure ensures that the extension rods on both sides of the mobile frame are aligned with the track grooves on the fixed frame during hopper installation. Then, the mobile frame is pushed to move the extension rods into the track grooves until one end of the positioning groove on the extension rod contacts the positioning post in the track groove. At this point, the upper and lower ends of the hopper are aligned with the expansion cylinder and the base, respectively. This structure enables rapid hopper installation and positioning, simplifies the steps of adjusting the hopper position, increases the speed of hopper installation, and greatly improves the efficiency and convenience of feeding.

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0020] Reference Figure 1 and Figure 2This utility model describes a mobile feeding device for a fluidized bed dryer. The main structure includes a hopper 3 positioned between a base 1 and an expansion cylinder 2. A fixing frame 4 is welded or bolted between the base 1 and the expansion cylinder 2. The fixing frame 4 is anchored to the ground. Both the base 1 and the expansion cylinder 2 are connected to the fixing frame 4, which supports them and maintains their stability. A bag filter is installed at the top of the expansion cylinder 2 to allow moisture generated during drying to pass through while blocking powder, thus achieving rapid drying of the material. An air inlet pipe is connected to the base 1, allowing purified and heated air to enter. After the hopper 3 is installed between the base 1 and the expansion cylinder 2, hot air passes through the hopper. The material enters the hopper 3 through the perforated plate at the bottom and diffuses within the expansion cylinder 2, causing the material to boil, thus achieving rapid drying. The structure of the base 1 and the expansion cylinder 2 is the same as that of existing fluidized bed dryers. This application does not improve the structure of either. For specific structures, refer to the vertical high-efficiency fluidized bed dryer produced by Changzhou Fubang Drying Equipment Co., Ltd. The structure of either is not considered an inventive point and will not be elaborated here. A movable frame 5 is fixed to the hopper 3 by welding or bolts. The bottom of the movable frame 5 is equipped with multiple movable wheels 6. This structure allows the movable frame 5 to move the hopper 3, thereby enabling the hopper 3 to be disassembled and assembled, facilitating feeding and unloading operations. The sides of the hopper 3 are connected to the movable frame 6. The frame 5 is rotatably connected via bearings. This structure allows the hopper 3 to rotate during material handling, tilting it to facilitate dumping and unloading. A guide frame 7 is fixed to the movable frame 5 by welding or bolts. The guide frame 7 has a through guide hole 8. A guide post 9 is fixed to the hopper 3 by welding or bolts, and the guide post 9 is slidably connected within the guide hole 8. In this structure, the guide post 9 slides within the guide hole 8 as the hopper 3 rotates. The guide post 9 is equipped with a limiting component that works in conjunction with the guide frame 7. This structure, when the hopper 3 rotates to a certain angle for dumping and unloading, uses the limiting component to fix the relative position of the guide post 9 and the guide frame 7, keeping the hopper 3 tilted. The angle eliminates the need for manual holding and fixing of the hopper 3, improving the convenience of material retrieval after drying. Simultaneously, the limiting component maintains the stability of the hopper 3 during operation, enhancing the stability of the hopper 3's fit with the base 1 and expansion cylinder 2, and ensuring overall sealing. The bottom of the movable frame 5 is symmetrically fixed with extension rods 10 via welding or bolts on both sides. The fixed frame 4 is symmetrically fixed with track grooves 11 on both sides via welding or bolts for use with the extension rods 10. The track grooves 11 consist of two track plates. With this structure, when the movable frame 5 moves the hopper 3 for installation, simply controlling the extension rods 10 to enter the track grooves 11 allows the hopper 3 to move accurately towards the position directly opposite the base 1 and expansion cylinder 2.A positioning post 12 is fixed to the track groove 11 by welding or bolts. The extension rod 10 has a positioning groove 13 that works in conjunction with the positioning post 12. The positioning groove 13 is recessed downwards from the top of the extension rod 10. After the extension rod 10 enters the track groove 11, the positioning post 12 enters the positioning groove 13 and moves along it. When the positioning post 12 moves to one end of the positioning groove 13, the upper and lower ends of the hopper 3 are aligned with the expansion cylinder 2 and the base 1, respectively. This structure, driven by the moving frame 5, moves the hopper 3, causing the extension rod 10 to move within the track groove 11 until one end of the positioning groove 13 on the extension rod 10 contacts the positioning post 12 in the track groove 11. At this point, the hopper 3 is positioned between the base 1 and the expansion cylinder 2, aligning with both. This structure eliminates the need for frequent adjustments to the hopper 3's position after installation, greatly simplifying the installation process, increasing the installation speed of the hopper 3, and thus improving the efficiency and convenience of feeding.

[0021] Preferred, refer to Figure 3 and Figure 6 The limiting assembly includes limiting holes 14 and limiting posts 15. The limiting holes 14 are symmetrically arranged on the guide frame 7, and are recessed inward from the surface of the guide frame 7. The limiting holes 14 are arrayed at different positions on the guide frame 7, so that when the hopper 3 rotates at different angles, there is a corresponding limiting hole 14 that cooperates with the limiting post 15, allowing the hopper 3 to be maintained at different angular positions. A sliding post 16 is slidably connected to the guide post 9 along the axial direction. The limiting posts 15 are symmetrically fixed to the sliding post 16 by welding or bolts. On 6, the limiting post 15 is movably inserted into the limiting hole 14. With this structure, when the hopper 3 rotates, the sliding post 16 slides outward, causing the limiting post 15 on the sliding post 16 to separate from the limiting hole 14. When the hopper 3 rotates to a certain angle, the sliding post 16 slides in the opposite direction, causing the limiting post 15 to enter the limiting hole 14 at the corresponding position on the guide frame 7. This prevents the guide post 9 from continuing to slide relative to the guide hole 8, thereby fixing the position of the hopper 3. It eliminates the need for manual holding of the hopper 3 and improves the convenience of limiting and fixing the hopper 3.

[0022] Preferably, the guide post 9 is provided with a sliding hole 17, which is recessed inward from the end of the guide post 9. The sliding post 16 is slidably connected in the sliding hole 17. This arrangement makes the sliding structure of the sliding post 16 relative to the guide post 9 more stable. A compression spring 18 is provided between the end of the sliding post 16 and the sliding hole 17. When the hopper 3 rotates, the sliding post 16 slides outward, compressing the compression spring 18 between the sliding post 16 and the sliding hole 17. After the hopper 3 rotates to the position, the sliding post 16 is released, and under the elastic force of the compression spring 18, the sliding post 16 automatically slides back towards the inside of the sliding hole 17. This allows the limiting post 15 on the sliding post 16 to automatically insert into the corresponding limiting hole 14. Under the action of the compression spring 18, the limiting post 15 is kept in a movable insertion state with the limiting hole 14, which further simplifies the limiting operation steps and improves the convenience of fixing the position of the hopper 3.

[0023] Preferably, a protruding plate 19 is fitted onto the sliding column 16 by welding or bolting. The protruding plate 19 is slidably connected to the sliding hole 17. A locking edge 20 is fixed to the end of the sliding hole 17 by welding or integral forming. The locking edge 20 has an inner hole with a diameter smaller than that of the sliding hole 17. The sliding column 16 passes through the inner hole of the locking edge 20 and is slidably connected to it. The compression spring 18 is disposed between the protruding plate 19 and the locking edge 20. This structure allows the sliding column 16 to accurately compress the compression spring 18 between the protruding plate 19 and the locking edge 20 when it slides in the sliding hole 17, ensuring the accuracy of its subsequent sliding reset. Furthermore, the cooperation between the protruding plate 19 and the locking edge 20 prevents the sliding column 16 from slipping off the sliding hole 17, improving the firmness of the sliding column 16 in the sliding hole 17 and enhancing the overall structural stability.

[0024] Preferred, refer to Figure 4 The guide hole 8 is arc-shaped, and the arc-shaped structure matches the arc-shaped movement trajectory of the guide post 9. The limiting holes 14 are arranged in a circular array on the side of the guide hole 8. With this structure, when the hopper 3 rotates at a certain angle, the guide post 9 also rotates at the corresponding angle within the guide hole 8. At this time, the limiting post 15 can accurately cooperate with the limiting hole 14 at the specified angle position, making the fixation of the hopper 3 position more accurate.

[0025] Preferred, refer to Figure 5 The ends of the track groove 11 are symmetrically fixed with arc-shaped transition plates 21 for use with extension rod 10 by welding or integral molding. The arc-shaped transition plates 21 are flared, which increases the opening range of the end of the track groove 11, making it easier for the extension rod 10 to enter the track groove 11, saving the time for the operator to align the extension rod 10 with the track groove 11, and further improving the installation efficiency of the hopper 3.

[0026] Preferably, a guide wheel 22 is rotatably connected to the arc-shaped transition plate 21 via a bearing. The guide wheel 22 makes rolling contact with the extension rod 10. This structure allows the extension rod 10 to make rolling contact with the guide wheel 22 when it enters the range of the two arc-shaped transition plates 21, making the movement of the extension rod 10 relative to the arc-shaped transition plate 21 smoother. This allows the extension rod 10 to enter the track groove 11 more smoothly, thus making the cooperation process between the extension rod 10 and the track groove 11 smoother.

[0027] Working Principle: This invention features a hopper 3 mounted on a movable frame 5. The movable frame 5 has wheels 6 at its bottom and a guide frame 7 on it. The guide frame 7 has guide holes 8. A guide post 9 on the hopper 3 is slidably connected within the guide hole 8. The guide post 9 has a limiting component that works in conjunction with the guide frame 7. When removing material from the hopper 3, simply rotating the hopper 3 causes the guide post 9 to slide within the guide hole 8. Once rotated to the correct position, the limiting component fixes the relative positions of the guide post 9 and the guide frame 7, maintaining the hopper 3 at an angle. This makes it easier to remove material from the hopper 3 without manual handling, significantly reducing the workload and improving convenience and efficiency. Extension rods 10 are symmetrically arranged on both sides of the bottom of the movable frame 5, and the fixed frame 4 has symmetrically arranged extension rods 10 on both sides. The extension rod 10 uses a track groove 11, and a positioning post 12 is provided in the track groove 11. The extension rod 10 is provided with a positioning groove 13 that cooperates with the positioning post 12. When the positioning post 12 moves to one end of the positioning groove 13, the upper and lower ends of the hopper 3 are aligned with the expansion cylinder 2 and the base 1, respectively. When installing the hopper 3, this structure makes the extension rods 10 on both sides of the moving frame 5 aligned with the track groove 11 on the fixed frame 4. Then, the moving frame 5 is pushed to move, so that the extension rod 10 enters the track groove 11 until one end of the positioning groove 13 on the extension rod 10 contacts the positioning post 12 in the track groove 11. At this time, the upper and lower ends of the hopper 3 are aligned with the expansion cylinder 2 and the base 1, respectively. This structure can quickly realize the installation and positioning of the hopper 3, simplify the steps of adjusting the position of the hopper 3, improve the installation speed of the hopper 3, and greatly improve the efficiency and convenience of feeding.
