[0002] A fluidized bed dryer is a device that uses fluidization technology to dry materials. It is usually applicable to the drying or cooling of granular and flaky materials and is widely used in industries such as grain, food, and chemical engineering.
[0003] In the existing fluidized bed dryer, due to the ventilation holes provided on the vibration plate, smaller particles in the material may fall downward through the ventilation holes to the bottom of the device, and the fallen materials cannot be collected, resulting in waste. At the same time, if too much material enters at one time, it may cause material accumulation, making the vibration plate unable to vibrate it completely, resulting in poor vulcanization effect. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides a fluidized bed dryer, which has the advantages of material collection and small-batch feeding, and solves the problems put forward in the above background technique.
[0005] The utility model provides the following technical solution: A fluidized bed dryer includes a box body. The outer wall of the box body is respectively fixedly installed with a vibration motor and an air inlet assembly. The top of the box body is respectively fixedly installed with an exhaust assembly and a hopper. The outer wall of the box body is fixedly installed with a main discharge port. The inner wall of the box body is fixedly equipped with a vibration plate. The bottom of the inner wall of the box body is provided with an inclined sliding bottom. The outer wall of the box body is fixedly installed with a collection pipe. One side of the collection pipe close to the box body is provided with a collection port. The bottom of the inner wall of the collection pipe is provided with a slideway. The bottom of the collection pipe is provided with a secondary discharge port. The top of the box body is fixedly installed with a servo motor. The power output shaft of the servo motor is fixedly installed with a rotating wheel. One end of a connecting rod is rotatably connected to the outer wall of the rotating wheel. The other end of the connecting rod is rotatably connected to a closing plate.
[0006] As a preferred technical solution of the utility model, the outer wall of the box body is provided with an inclined groove, and the length of the inclined groove is the same as the length of the collection port.
[0007] As a preferred technical solution of the utility model, the secondary discharge port is communicated with the inner wall of the collection pipe, and the secondary discharge port is located on the bottommost side of the collection port.
[0008] As a preferred technical solution of the utility model, the number of the collection pipes, collection ports, slideways and secondary discharge ports is two, and the two collection pipes, collection ports, slideways and secondary discharge ports are symmetrically distributed on both sides of the box body. Both sides of the box body are provided with inclined grooves.
[0009] As a preferred technical solution of the present utility model, the closing plate is located on the inner wall of the hopper, and the closing plate completely closes the bottom of the inner wall of the hopper.
[0010] As a preferred technical solution of the present utility model, an extension column is provided on the side of the rotating wheel away from the servo motor, and the extension column is located at a position away from the center of the rotating wheel. The connecting rod is rotationally connected to the rotating wheel through the extension column.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] 1. In this fluidized bed dryer, when the material falls through the ventilation holes opened above the vibrating plate, the material falls above the inclined sliding bottom and slides to both sides through the inclined angle of the inclined sliding bottom. When it slides to the inclined groove on the outer wall of the box body, it enters the inside of the collecting pipe through the inclined groove and the collecting port on the outer wall of the box body, slides in the direction of the secondary discharge port through the slideway, and the aftershock of the vibrating motor makes its sliding speed faster, and finally it is discharged from the secondary discharge port.
[0013] 2. In this fluidized bed dryer, by starting the servo motor, the servo motor drives the rotating wheel to rotate, the rotating wheel drives the external extension column to rotate, and through the rotation of the external extension column of the rotating wheel, one end of the connecting rod is driven to move, thereby driving the closing plate to move towards the connecting rod. At this time, a gap is generated between the closing plate and the inner wall of the hopper, so that the material can enter the inside of the box body through the closing plate. When the rotating wheel rotates back, the connecting rod is reset, so that the closing plate closes the inner wall of the hopper, thereby blocking the feeding. Through the continuous rotation of the rotating wheel, the material is put in small batches, thereby avoiding the phenomenon of material accumulation. Brief Description of the Drawings

[0021] Please refer to Figures 1-5 , a fluidized bed dryer, including a box body 1, a vibration motor 2 and an air inlet assembly 4 are respectively fixedly installed on the outer wall of the box body 1, an exhaust assembly 3 and a hopper 7 are respectively fixedly installed on the top of the box body 1, a main discharge port 5 is fixedly installed on the outer wall of the box body 1, a vibration plate 6 is fixedly assembled on the inner wall of the box body 1, an inclined sliding bottom 8 is arranged at the bottom of the inner wall of the box body 1, a collecting pipe 9 is fixedly installed on the outer wall of the box body 1, a collecting port 10 is opened on one side of the collecting pipe 9 close to the box body 1, a slideway 11 is arranged at the bottom of the inner wall of the collecting pipe 9, a secondary discharge port 12 is opened at the bottom of the collecting pipe 9, a servo motor 13 is fixedly installed on the top of the box body 1, a rotating wheel 14 is fixedly installed on the power output shaft of the servo motor 13, one end of a connecting rod 15 is rotatably connected to the outer wall of the rotating wheel 14, and the other end of the connecting rod 15 is rotatably connected to a closing plate 16. In the above structure, the position of the main discharge port 5 is lower than that of the vibration plate 6. The vibration of the vibration plate 6 moves the materials above the vibration plate 6 in the direction of the main discharge port 5. When the materials reach above the main discharge port 5, the materials are discharged through the main discharge port 5 by gravity.
[0022] In a preferred implementation mode, an inclined groove is opened on the outer wall of the box body 1, and the length of the inclined groove is the same as that of the collecting port 10. In the above structure, when smaller materials fall from the ventilation holes opened above the vibration plate 6, they fall above the inclined sliding bottom 8 and slide to both sides through the inclined angle of the inclined sliding bottom 8. When they slide to the inclined groove on the outer wall of the box body 1, they enter the inside of the collecting pipe 9 through the inclined groove on the outer wall of the box body 1.
[0023] In a preferred implementation mode, the secondary discharge port 12 is communicated with the inner wall of the collecting pipe 9, and the secondary discharge port 12 is located on the bottommost side of the collecting port 10. In the above structure, when the materials enter the inside of the collecting pipe 9, they slide in the direction of the secondary discharge port 12 through the slideway 11, and the aftershock of the vibration motor 2 makes their sliding speed faster, and finally they are discharged through the secondary discharge port 12.
[0024] In a preferred embodiment, the number of the collecting pipes 9, the collecting ports 10, the chutes 11 and the secondary discharge ports 12 is two, and the two collecting pipes 9, the collecting ports 10, the chutes 11 and the secondary discharge ports 12 are symmetrically distributed on both sides of the box body 1. Oblique chutes are provided on both sides of the box body 1. In the above structure, the materials can be discharged from both sides through the two oblique chutes.
[0025] In a preferred embodiment, the closing plate 16 is located on the inner wall of the hopper 7, and the closing plate 16 completely closes the bottom of the inner wall of the hopper 7. In the above structure, the bottom of the hopper 7 is closed by the closing plate 16, so that the materials on the inner wall of the hopper 7 above the closing plate 16 are blocked, and further the closing plate 16 cuts off the materials and no longer inputs the materials into the interior of the box body 1.
[0026] In a preferred embodiment, an extension column is provided on the side of the rotating wheel 14 away from the servo motor 13, and the extension column is located at a position away from the center of the rotating wheel 14. The connecting rod 15 is rotationally connected to the rotating wheel 14 through the extension column. In the above structure, by starting the servo motor 13, the servo motor 13 drives the rotating wheel 14 to rotate, the rotating wheel 14 drives the extension column outside the rotating wheel 14 to rotate, and by the rotation of the extension column outside the rotating wheel 14, one end of the connecting rod 15 is driven to move, and further the closing plate 16 is driven to move towards the connecting rod 15, so that a gap is generated between the closing plate 16 and the inner wall of the hopper 7, and further the materials enter the interior of the box body 1 through the closing plate 16. When the rotating wheel 14 rotates back, the connecting rod 15 is reset, so that the closing plate 16 closes the inner wall of the hopper 7, and further the feeding is blocked.
[0027] Working principle: Place the material in the hopper 7. Start the servo motor 13. The servo motor 13 drives the rotating wheel 14 to rotate. The rotating wheel 14 drives the extension column outside the rotating wheel 14 to rotate. By the rotation of the extension column outside the rotating wheel 14, one end of the connecting rod 15 is driven to move, and then the closing plate 16 is driven to move towards the connecting rod 15, causing a gap between the closing plate 16 and the inner wall of the hopper 7. As a result, the material enters the interior of the box body 1 through the closing plate 16. When the rotating wheel 14 rotates back, the connecting rod 15 is reset, causing the closing plate 16 to close the inner wall of the hopper 7, thereby blocking the feeding. Through the continuous rotation of the rotating wheel 14, the material falls in small batches above the vibrating plate 6. At this time, start the vibrating motor 2, the exhaust assembly 3, and the intake assembly 4. Hot air is discharged into the interior of the box body 1 through the intake assembly 4. The hot air moves upward and is discharged through the exhaust assembly 3. The vibrating motor 2 vibrates the vibrating plate 6 and moves the material towards the main discharge port 5 through vibration. The vulcanized material is discharged through the main discharge port 5. When smaller materials fall through the ventilation holes opened above the vibrating plate 6, they fall above the inclined sliding bottom 8 and slide to both sides through the inclined angle of the inclined sliding bottom 8. When they slide to the inclined groove on the outer wall of the box body 1, they enter the interior of the collecting pipe 9 through the inclined groove on the outer wall of the box body 1. When the material enters the interior of the collecting pipe 9, it slides towards the secondary discharge port 12 through the slideway 11. The aftershock of the vibrating motor 2 accelerates its sliding speed, and finally it is discharged through the secondary discharge port 12.
[0028] Although the embodiments of the present invention 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 invention. The scope of the present invention is defined by the appended claims and their equivalents.
