[0018] 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.

[0019] Reference Figure 1 and Figure 2This utility model describes a hopper cleaning device for a fluidized bed dryer. The main structure includes a water inlet pipe 2 mounted on a movable frame 1. One end of the water inlet pipe 2 has a connector, which can be used to connect to the water supply pipe of a water supply system. The connection can be made using threads or clamps, allowing clean water from the water supply system to smoothly enter the water inlet pipe 2. The bottom of the movable frame 1 has multiple rollers 3, preferably casters, for easy movement of the movable frame 1. A feeding hopper 4 is rotatably connected to the movable frame 1 via bearings. The feeding hopper 4 is an open-top hopper structure made of stainless steel or other metal materials. Limit plates 5 are fixed to the sides of the feeding hopper 4 by welding or bolts. The movable frame 1 has a matching limit... The locking rod 6 used in the positioning plate 5 ensures that when the feeding hopper 4 is filled with raw materials and enters the fluidized bed dryer for drying, the locking rod 6, in conjunction with the limiting plate 5, keeps the feeding hopper 4 vertical, thus guaranteeing accurate alignment with the fluidized bed dryer and ensuring the drying effect. When unloading is required after drying, the moving frame 1 is used to move the feeding hopper 4 out, and then the locking rod 6 is released from the limiting plate 5, allowing the feeding hopper 4 to rotate and easily empty the dried raw materials. This makes loading and unloading the feeding hopper 4 more convenient. The moving frame 1 is rotatably connected to a rotating shaft 7 via bearings. A crank handle 8 is fixed to the end of the rotating shaft 7 by welding or bolts. The crank handle 8 is used to reciprocate the rotation of the rotating shaft 7. The crank handle 8 is equipped with a corresponding moving frame. The positioning post 9 used restricts the position of the crank handle 8, ensuring that the rotating shaft 7 will not rotate when the hopper 4 is not being cleaned. This makes the overall structure of the moving frame 1 more stable and will not interfere with the loading and unloading process of the hopper 4. The water inlet pipe 2 is fixed to the rotating shaft 7 by welding or bolts. A cleaning pipe 10 is connected to the end of the water inlet pipe 2 near the hopper 4. The cleaning pipe 10 is equipped with multiple cleaning nozzles 11, which are oriented towards the inside of the rotated hopper 4. With this structure, when cleaning the hopper 4, it is only necessary to use the moving frame 1 to move the hopper 4 to the cleaning position, and then release the locking rod 6 from the limiting plate 5, allowing the hopper 4 to rotate freely. Then, one end of the inlet pipe 2 is connected to the water supply pipe of the water supply system. At this time, the pressurized cleaning water from the water supply system can pass through the multiple cleaning nozzles 11 on the cleaning pipe 10 and spray out. The hopper 4 is rotated toward the cleaning nozzles 11, so that the multiple cleaning nozzles 11 can spray water to rinse the inside of the hopper 4. The positioning column 9 is released from its restriction on the crank handle 8, and the crank handle 8 is used to reciprocate the rotating shaft 7, thereby causing the cleaning pipe 10 and the cleaning nozzles 11 to swing, so as to rinse all parts of the inside of the hopper 4 more thoroughly and evenly. After rinsing, the hopper 4 is rotated again to pour out the wastewater, making the cleaning operation of the hopper 4 more convenient, and there is less material residue after cleaning, which greatly improves the convenience of cleaning.This allows for a more thorough cleaning of the interior of hopper 4.

[0020] Preferred, refer to Figure 5 The end of the water inlet pipe 2 is connected to a connecting pipe 12. The cleaning pipe 10 is annular, and both ends of the connecting pipe 12 are connected to the cleaning pipe 10. This structure allows the cleaning nozzles 11 to be distributed in a circular array along the annular cleaning pipe 10. This allows the cleaning water to enter the annular cleaning pipe 10 from the water inlet pipe 2 and the connecting pipe 12, and then be sprayed out from the multiple cleaning nozzles 11 in the circular array. This enables simultaneous rinsing of various positions inside the hopper 4, further improving the comprehensiveness and uniformity of the cleaning and enhancing the cleaning effect.

[0021] Preferably, the end of the water inlet pipe 2 away from the feeding hopper 4 is provided with an external thread. This structure makes it easy for the water inlet pipe 2 to be connected to the water supply pipe of the water supply system through a threaded connection, further simplifying the connection operation steps and improving the convenience of using the device.

[0022] Preferred, refer to Figure 3 The positioning post 9 passes through the crank handle 8 and is threaded to it. The end of the positioning post 9 passes through the crank handle 8 and is movably inserted into the moving frame 1. Specifically, the moving frame 1 is provided with a positioning hole, and the end of the positioning post 9 is movably inserted into the positioning hole. With this structure, the end of the positioning post 9 can be rotated forward or backward by simply rotating the positioning post 9, thereby inserting or separating it from the positioning hole on the moving frame 1. This makes the positioning operation of the crank handle 8 relative to the moving frame 1 more convenient and stable.

[0023] Preferably, the movable frame 1 is symmetrically fixed with fixing plates 13 by welding or bolts. The two sides of the feeding hopper 4 are respectively rotatably connected to the fixing plates 13 on both sides through bearings. The locking rod 6 is set on the fixing plate 13. This structure allows the fixing plate 13 to not only provide a fixed position for the rotation of the feeding hopper 4, but also to provide a fixed position for the locking rod 6. The locking rod 6 is set directly below the rotation position of the feeding hopper 4. In this way, when the feeding hopper 4 rotates to the vertical direction, the locking rod 6 can accurately cooperate with the limiting plate 5 on the side of the feeding hopper 4, making the locking and fixing of the feeding hopper 4 more convenient and efficient.

[0024] Preferred, refer to Figure 4The fixing plate 13 is fixed with a sleeve 14 by welding or bolts. The locking rod 6 is slidably connected inside the sleeve 14. The limiting plate 5 is provided with a through limiting hole 15. The end of the locking rod 6 passes through the sleeve 14 and extends into the limiting hole 15. With this structure, when the feeding hopper 4 rotates to the vertical direction, the limiting hole 15 on the limiting plate 5 is aligned with the locking rod 6. At this time, it is only necessary to push the locking rod 6 in the direction of the feeding hopper 4 to make the locking rod 6 slide inside the sleeve 14 and extend into the limiting hole 15, thereby restricting the rotation of the limiting plate 5, so that the feeding hopper 4 cannot continue to rotate and thus maintains a vertical state, making the rotation limitation of the feeding hopper 4 more secure and accurate.

[0025] Preferably, the width of the bottom side of the movable frame 1 is greater than the width of the top side, and the feeding hopper 4 is rotatably connected to the top side of the movable frame 1. This structure makes the side of the movable frame 1 narrower at the top and wider at the bottom, and the feeding hopper 4 is located in the middle of the side of the movable frame 1, which makes the overall movable frame 1 more stable and less prone to tipping over when moving, further ensuring the stability of the feeding hopper 4 when moving and loading / unloading materials.

[0026] Working Principle: This invention features a water inlet pipe 2 mounted on a movable frame 1. A cleaning pipe 10 is connected to the water inlet pipe 2, and multiple cleaning nozzles 11 are mounted on the cleaning pipe 10, facing the interior of the rotated hopper 4. With this structure, simply move the movable frame 1 to the cleaning position, connect the end of the water inlet pipe 2 to the water supply system, and allow cleaning water to enter the cleaning pipe 10 through the water inlet pipe 2 and be sprayed out through the multiple cleaning nozzles 11. Then, simply release the locking rod 6 from the side limiting plate 5 of the hopper 4, rotate the hopper 4 towards the cleaning nozzles 11, and the cleaning nozzles 11 will automatically rinse the interior of the rotated hopper 4. After rinsing, continue rotating the hopper 4 to empty the remaining cleaning water. This design makes cleaning the inside of the hopper 4 more convenient and less prone to material residue, greatly improving the ease of cleaning the inside of the hopper 4 and making the cleaning of the hopper 4 more thorough. A rotating shaft 7 is rotatably connected to the moving frame 1, and a crank handle 8 is provided at the end of the rotating shaft 7. The crank handle 8 is provided with a positioning post 9 for use with the moving frame 1. The water inlet pipe 2 is set on the rotating shaft 7. This structure can release the restriction of the positioning post 9 when the cleaning nozzle 11 is used to rinse the inside of the hopper 4. The crank handle 8 drives the rotating shaft 7 to rotate back and forth, which in turn causes the water inlet pipe 2 on the rotating shaft 7 to swing back and forth. This allows the cleaning water sprayed by the cleaning nozzle 11 to rinse different parts of the inside of the hopper 4 more evenly and comprehensively, further improving the cleaning effect.
