Technical Field
[0001] This utility model relates to a dryer, and more particularly to a fluidized bed dryer. Background Technology
[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.
[0003] Fluidized bed dryers, technically speaking, suspend granular solid materials under the action of a hot airflow, presenting them in a fluid-like state. This fluidization process achieves efficient heat and mass exchange between the gas and solid phases, thus achieving the drying purpose. Various application fields require rapid and uniform material drying to ensure product quality stability and production continuity, while also meeting hygiene standards. This has driven the continuous innovation and widespread application of fluidized bed dryers.
[0004] Fluidized bed dryers are relatively simple in form, typically represented by a single-layer cylindrical type. However, these early fluidized bed dryers suffer from uneven moisture content in the dried product due to the wide distribution of material residence time within the fluidized bed. Furthermore, the diameter of the equipment cannot be too large. Existing fluidized bed dryers use vibrating motors to improve the uniformity of heating and drying, ensuring the drying effect. However, the vibration effect of the aforementioned fluidized bed during the drying process is poor, with a low frequency, resulting in poor drying uniformity and effect, reducing drying efficiency. In addition, wet materials tend to clump together in the dryer chamber, making it difficult to effectively dry the materials and meet the application requirements.

[0040] like Figure 2 As shown, one embodiment of this utility model provides a fluidized bed dryer, including a vibration table 1. A servo motor 2 3 is fixedly connected to the left side of the inner wall of the vibration table 1. A linkage component 4 is fixedly connected to the output end of the servo motor 2 3. Multiple rotating shafts 5 are fixedly connected to the right end of the linkage component 4. Multiple vibrating blocks 6 are fixedly connected to the left and right sides of the outer wall of the rotating shafts 5.

[0041] Among them, the linkage component 4, such as Figure 6 As shown, in one embodiment, the output end of the servo motor 3 and one end of the rotating shaft 5 are equipped with gears, which are connected by a belt to achieve transmission.
[0042] In one embodiment, the linkage component 4 has two or more output ends, which are respectively fixedly connected to one end of two or more rotating shafts 5. The rotating shafts 5 are respectively provided with the vibration block 6 and the vibration column 7.
[0043] In one embodiment, the number of vibrating blocks 6 on the rotating shaft 5 is two or more.
[0044] In one embodiment, the number of vibrating columns 7 can be multiple, with a minimum of 1;
[0045] In one embodiment, the number of distributed networks 203 can be two or more, and a multi-layered configuration can be adopted.
[0046] The vibration table 1 is the main part of the entire device. During use, the servo motor 2 3 provides sufficient power to the equipment. The servo motor 2 3 serves as a power output device, and its output end is fixedly connected to the linkage component 4. The linkage component 4 drives multiple rotating shafts 5, enabling the vibrating block 6 to move. The vibrating column 7 enables the vibration table 1 to produce a uniform and effective vibration effect. The vibration table 1, through the sliding column 8 and the spring 9, provides a certain elastic support to ensure that the sliding column 8 remains stable during vibration, so that the bed 10 and the bed board 11 vibrate. Then, through the connected hot air fan 12, heat is provided to the bed 10 to meet the drying requirements in the material processing process.
[0047] like Figure 1 As shown, a dispersing mechanism 2 is provided on the top of the bed 10 to disperse materials and prevent them from sticking together, ensuring that the materials can be evenly dispersed and avoiding the material processing effect due to sticking.
[0048] like Figure 3 As shown, the dispersing mechanism 2 includes a bed cover 201. The bottom end of the bed cover 201 is fixedly connected to the top edge of the bed body 10. The top left side of the bed cover 201 is fixedly connected to a feed inlet 202. Multiple dispersing nets 203 are fixedly connected to the top of the inner wall of the feed inlet 202. A mounting plate 204 is fixedly connected to the front left side of the bed cover 201. A servo motor 205 is fixedly connected to the rear side of the mounting plate 204.
[0049] like Figure 4 As shown, a rotating rod 206 is fixedly connected to the output end of the servo motor 205, and multiple dispersing columns 207 are fixedly connected to the outer wall of the rotating rod 206.
[0050] In use, the bed cover 201 is tightly integrated with the bed body 10 to ensure structural stability. There is a feed inlet 202 on the top left side of the bed cover 201. Multiple dispersing nets 203 are evenly fixedly connected to the top of the inner wall of the feed inlet 202. The function of these dispersing nets 203 is to evenly disperse the material to ensure the uniformity of subsequent processing. The mounting plate 204 is fixedly connected to a servo motor 205 to provide power to the rotating rod 206. Multiple dispersing columns 207 are evenly fixedly connected to the outer wall of the rotating rod 206. Driven by the rotating rod 206, these dispersing columns 207 can efficiently disperse the material to achieve the expected material processing effect.
[0051] like Figure 5 As shown, a controller 13, a display screen 14, multiple buttons 15 and a power button 16 are fixedly installed on the middle left side of the vibration table 1. The controller 13 is electrically connected to the servo motor 1 205, the servo motor 2 3, the display screen 14, the multiple buttons 15 and the power button 16.
[0052] A support plate 17 is fixedly connected to the bottom of the vibration table 1, and multiple fixing holes 18 are provided at the top corners of the support plate 17.
[0053] In use, button 15 allows the operator to easily perform various control operations, while power button 16 is responsible for the power switch function of the device.
[0054] The fixing hole 18 can be used to firmly fix the vibration table 1 in a specific position to adapt to different usage environments and needs.
[0055] like Figure 1 As shown, the top left and right sides of the bed cover 201 are connected to multiple exhaust pipes 19, the top of the exhaust pipe 19 is fixedly connected to a connecting pipe 20, and the top right side of the connecting pipe 20 is fixedly connected to a connecting ring 21.
[0056] A discharge port 22 is fixedly connected to the right side of the bed 10, and multiple decorative blocks 23 are fixedly connected to the front and rear sides of the bed 10. A reinforcing block 24 is fixedly connected to the bottom of the outer wall of the feed port 202.
[0057] In use, multiple exhaust pipes 19 at the top of the bed cover 201 are connected to a connecting pipe 20 to expel moisture. The connecting pipe 20 is fixedly connected to a connecting ring 21 for connection with other components. A discharge port 22 is fixedly connected to the right side of the bed body 10 to discharge the dry material inside the bed cover 201. Multiple decorative blocks 23 connected to the bed body 10 not only serve an aesthetic purpose but also provide structural support. A reinforcing block 24 is also fixedly connected to the bottom of the outer wall of the feed inlet 202 to enhance the structural strength and stability of the feed inlet 202.
[0058] In summary, when this utility model is in operation: the servo motor 3 on the vibration table 1 is started, driving the linkage component 4 at its output end to move, thereby driving the rotating shaft 5 to rotate. The rotating shaft 5 is fixedly connected to the vibration block 6, so the vibration block 6 can rotate together. Since multiple vibration columns 7 are rotatably connected to the vibration block 6, and the bed 10 is slidably connected to the vibration table 1 through the sliding column 8, and the spring 9 is set on the outer wall of the sliding column 8 to provide shock absorption and reset effect, the vibration columns 7 rotatably connected to the vibration block 6 can push the bed 10 to move up and down, thereby causing the bed board 11 on the bed 10 to vibrate. Hot air is output from the bottom of the bed board 11 by the hot air blower 12 and sprayed upward to achieve the drying effect. This structure can increase the vibration frequency, ensure the uniformity of material drying, improve the drying efficiency and effect, and meet the drying requirements.
[0059] By installing a feed inlet 202 on the bed cover 201, the material can easily enter. When the material enters, it will first come into contact with the dispersing mesh 203, which will initially disperse the adhesion between the materials. A servo motor 205 is installed on the feed inlet 202 through the mounting plate 204. When the servo motor 205 is started, the rotating rod 206 at its output end will rotate, thereby driving the dispersing column 207 to move. The initially dispersed material will come into contact with the dispersing column 207 downwards, and be further dispersed to avoid adhesion. This structure can ensure that the material does not stick together and pile up into clumps when it enters the fluidized bed dryer, ensuring the uniformity between the materials, improving the drying effect, and meeting the dispersing requirements.
[0060] This utility model provides a concept and method for a fluidized bed dryer. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
