[0024] For the embodiments, please refer to Figures 1-3 , the present utility model provides a technical solution:

[0025] A fluidized bed drying device, including a fluidized bed 1 and a drying box 2 arranged outside the fluidized bed 1. A wind distribution seat 3 is fixedly installed at the bottom of the fluidized bed 1. A wind distribution plate 301 is fixedly arranged at the top of the wind distribution seat 3. A support seat 4 is arranged below the wind distribution seat 3. A vibration mechanism 5 is arranged between the support seat 4 and the wind distribution seat 3. An exhaust port 6 is fixedly arranged at the outer top end of the fluidized bed 1. A bin door 7 is hermetically rotatably arranged at the outer bottom end of the fluidized bed 1. A feed port 8 is arranged at the top of the fluidized bed 1. A conveying pipe 201 is fixedly installed on the left side of the drying box 2. A heating chamber 202 is opened inside the drying box 2. A circulation fan 203 and a heater 204 are respectively arranged inside the heating chamber 202;

[0026] Specifically, the bottom end of the air distribution plate 301 extends to the inner top end of the air distribution base 3, and its top end extends to the bottom inner wall of the fluidized bed 1. A plurality of protruding air distribution holes are provided on the top of the air distribution plate 301, and the bottom inner wall of the air distribution holes extends to the bottom surface of the air distribution plate 301;

[0027] In this embodiment, the air distribution plate 301 is mainly arranged to connect the air distribution holes with the inside of the air distribution base 3 and the inside of the fluidized bed 1 respectively. Then, the hot air enters the fluidized bed 1 through the air distribution holes, enabling the particles in the fluidized bed 1 to be fluidized.

[0028] Specifically, the left end of the conveying pipe 201 is fixedly penetrated through the outer surface of the air distribution base 3 and extends inward. There are multiple heaters 204, and the vertical cross-sectional shape of the multiple heaters 204 is a circular structure;

[0029] In this embodiment, the heaters 204 are mainly used to generate heat energy, while the circulation fan 203 is mainly used to guide the heat energy and form hot air, so that the hot air enters the fluidized bed 1 through the conveying pipe 201, the air distribution base 3 and the air distribution holes, thus achieving the effect of drying the particles in the fluidized bed 1.

[0030] In this embodiment, please refer to Figure 1 and Figure 3 , the vibration mechanism 5 includes a vibration motor 501, a support sleeve 502 and a shock absorber 503. The vibration motor 501 is respectively fixedly installed at the front and rear ends outside the air distribution base 3. The support sleeve 502 and the shock absorber 503 are both fixedly installed on the top surface of the support base 4. A vibration piston rod 504 is provided at the top of the support sleeve 502, and a shock absorber spring 505 is sleeved outside the shock absorber 503;

[0031] Specifically, the support sleeve 502 and the shock absorber 503 are both symmetrically distributed about the top surface of the support base 4. The bottom of the vibration piston rod 504 fits and slides through the top surface of the support sleeve 502 and extends inward, and its top end and the top end of the shock absorber 503 are both fixed to the bottom surface of the air distribution base 3;

[0032] In this embodiment, the vibration motor 501 is arranged to drive the air distribution base 3 and the air distribution plate 301 to vibrate. This vibration method can reduce the accumulation of particles on the air distribution plate 301 and reduce the risk of blockage of the air distribution plate 301. The fitting and sliding between the vibration piston rod 504 and the support sleeve 502 can limit the air distribution base 3. The telescopic settings of the shock absorber 503 and the shock absorber spring 505 buffer and protect the air distribution base 3, thus improving the safety of the fluidized bed 1.

[0033] The working process of the utility model: When using the fluidized bed drying device, first pour the material particles into the fluidized bed 1 through the feed inlet 8, and then dry it. Under the action of the circulation fan 203, the heat energy generated by the heater 204 is transmitted to the air distribution seat 3 through the conveying pipe 201, and then enters the fluidized bed 1 through the air distribution holes on the air distribution plate 301. Under the influence of the air flow, the moisture in the particles is carried away by the air flow through the exhaust port 6, thus achieving the effect of drying the material particles. At the same time, start the vibration motor 501. Under the vibration of the vibration motor 501, the particles accumulated on the air distribution plate 301 are dispersed, avoiding the blockage of the air distribution plate 301, ensuring the passage of the heat energy air flow in the fluidized bed 1. During the vibration process, the vibration piston rod 504 gradually moves along the inner wall of the support sleeve 502, and the shock-absorbing spring 505 and the shock absorber 503 contract. Under the elastic force of the shock-absorbing spring 505, the impact force received by the air distribution seat 3 and the fluidized bed 1 during vibration is effectively reduced, facilitating the operation of the fluidized bed 1 and meeting the needs of the users.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
