It includes an exhaust hole, a feeder, a sieve plate, a dry material outlet, and a hot air inlet. An atomizer is installed at the original feeder inlet, and compressed air is used to make the medicine containing a certain amount of water enter the drying box in powder or mist form, so as to achieve rapid and uniform drying, expand the moisture content range of the traditional Chinese medicine extract of the feeder, save the time for the material to change from a fluid state to a solid dispersion, save production costs, and facilitate industrial production. In the process of realizing this application, the inventor found that the prior art has the following problems: When the existing fluidized bed drying equipment dries the material, the wind blown out by the blower is often output vertically upward without the function of swirling the airflow, which can easily make the material flow process relatively single, resulting in local overheating or uneven drying. At the same time, the filter plates are often fixedly connected, which can easily cause the material to block the filter plate during the drying process, and the material at the bottom of the filter plate is difficult to flow, resulting in agglomeration. Summary of the invention

[0003] The purpose of this application is to provide a fluidized bed drying device.

The drying chamber provides an environment suitable for material drying. At the same time, the drying chamber can be sealed and connected to the silo through the auxiliary sealing ring and the upper connecting ring. The mobile frame plays a supporting role, and the mobile frame can be connected and fixed to the silo and the bottom barrel through the connecting assembly. The rotating shaft can rotate in the mobile frame to drive the ring to rotate and drive the silo to dump, so as to discharge the dried material.

[0006] A servo motor is provided on one side of the movable frame, and the output end of the servo motor is connected to the rotating shaft on one side. A silo is embedded in the inner wall of the ring, and a bottom cylinder is connected to the bottom end of the silo. The ring and the silo are connected by bolts. The servo motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the ring to rotate synchronously, and the rotation of the ring drives the silo and the bottom cylinder to rotate synchronously.

[0007] By adopting the above technical solution, the servo motor plays a driving role. When the dried material needs to be discharged, the servo motor can drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the ring to rotate synchronously. The rotation of the ring drives the silo and the bottom cylinder to rotate synchronously, thereby dumping and discharging the material in the silo.

[0009] By adopting the above technical solution, the electric telescopic rod drives the arc-shaped clamping plate to perform translational movement to clamp and fix the bottom cylinder, thereby preventing the bottom cylinder and the silo from shaking. At the same time, the rubber pad is used to prevent the arc-shaped clamping plate from causing damage to the bottom cylinder. After drying, the electric telescopic rod can be retracted to cancel the positioning of the arc-shaped clamping plate on the bottom cylinder.

[0010] The top outer wall of the silo is connected with a lower connecting ring, the top of the lower connecting ring is provided with a ring groove, the upper connecting ring and the rubber ring are both embedded in the ring groove, the bottom side of the bottom cylinder is connected with an air inlet pipe, and the end of the air inlet pipe away from the bottom cylinder is connected with a high-speed hot air blower.

[0011] By adopting the above technical solution, when the silo and the drying chamber are connected, the two are first aligned, and then the silo can be driven to rise through the movable lifting mechanism, so that the upper connecting ring and the rubber ring are embedded in the ring groove, and the rubber ring plays a sealing role. At the same time, the auxiliary sealing ring is rotated to make the auxiliary sealing ring descend to wrap the upper connecting ring and the lower connecting ring, so as to achieve further sealing effect. Hot air can be output to the bottom of the device through the high-speed hot air blower and the air inlet pipe. The material is fluidized under the action of the hot air, and a strong heat and mass transfer process is carried out between the material and the hot air. The heat required for material dehydration is provided by the hot air, and the water in the material is evaporated and taken away by the drying medium.

[0012] The middle inner wall of the bottom tube is connected to a connecting frame No. 1, the center of the connecting frame No. 1 is connected to a limiting ring, the middle of the limiting ring is connected to a rotating rod through a bearing, the middle outer wall of the rotating rod is arranged with spiral blades, and the rotation of the spiral blades drives the rotating rod to rotate.

[0013] By adopting the above technical solution, the No. 1 connecting frame plays the role of connecting and limiting, and the rotating rod can rotate on the inner wall of the limiting ring. When the high-speed hot air blower outputs hot air flow, the air flow will drive the spiral blades to rotate after passing through the spiral blades, and the air flow will be output in a spiral shape. The air flow passing through each section of the spiral blade advances in the direction of rotation of the rotating rod. The swirling hot air can enhance fluid disturbance and improve the heat and mass transfer effects inside the fluid. The rotating flow can increase the contact area and mixing degree between material particles and hot air, thereby improving the drying efficiency.

[0019] By adopting the above technical solution, the rotating rod drives the driving shaft to rotate after being decelerated by the planetary reduction gear set, and the rotation of the driving shaft drives the connecting rod and the roller to rotate. The two sets of rollers rotate along the annular slideway. At the same time, since the rollers are in contact with the wave surface, the adjusting ring is pushed to perform reciprocating lifting and lowering motion while the rollers rotate, thereby driving the filter plate to continuously reciprocate and rise and fall, thereby achieving a shaking and vibrating effect on the material. The vibration can make the material constantly turn over during the drying process, so that the material is heated more evenly, the heat exchange efficiency is improved, thereby improving the drying intensity and reducing energy consumption.

[0020] The bottom end of the mobile frame is connected to a movable lifting mechanism, which includes an electric push rod, a base frame, and auxiliary moving wheels. The four ends of the bottom of the mobile frame are connected to electric push rods, and the bottom ends of multiple groups of electric push rods are connected to the base frame. Auxiliary moving wheels are arranged at the bottom end of the base frame. The electric push rod pushes and drives the mobile frame to perform lifting and lowering movements.

The heat required for dehydration of the material is provided by the hot air, and the water in the material is evaporated and taken away by the drying medium; When the high-speed hot air blower 14 outputs hot air flow, the air flow will drive the spiral blades 18 to rotate after passing through the spiral blades 18, and the air flow will be output in a spiral shape. The air flow passing through each section of the spiral blades 18 advances in the direction of rotation of the rotating rod 17. The swirling hot air can enhance fluid disturbance and improve the heat and mass transfer effect inside the fluid. The rotating flow can increase the contact area and mixing degree between the material particles and the hot air, thereby improving the drying efficiency. The rotating rod 17 drives the drive shaft 28 to rotate after being decelerated by the planetary reduction gear set 27. The rotation of the drive shaft 28 drives the connecting rod 29 and the roller 30 to rotate. The two sets of rollers 30 rotate along the annular slide 24. At the same time, because the rollers 30 are in contact with the wave surface 25, the adjusting ring 23 is pushed to perform a reciprocating lifting and lowering motion while the rollers 30 rotate, thereby driving the filter plate 19 to continuously reciprocate and rise and fall, thereby realizing a shaking and trembling effect on the material. The vibration can make the material constantly flip during the drying process, so that the material is affected. The heat is more uniform, the heat exchange efficiency is improved, thereby improving the drying intensity and reducing energy consumption. The airflow can be discharged through the exhaust pipe 201 on the top of the top cylinder 2. At the same time, the exhaust pipe 201 can be connected to a dust removal mechanism to perform subsequent processing on the discharged gas. The drying chamber 3 provides an environment suitable for material drying. After drying, the auxiliary sealing ring 6 can be rotated in the opposite direction so that the auxiliary sealing ring 6 rises, thereby canceling the wrapping of the upper connecting ring 4 and the lower connecting ring 11. The movable lifting mechanism 31 can drive the movable frame 7 to descend, thereby driving the silo 9 and the bottom cylinder 10 to descend and move in a translational manner, thereby pushing the silo 9 to separate from the drying chamber 3, and pulling the movable frame 7 out of the silo 9. The servo motor 803 can be used to drive the rotating shaft 802 to rotate, and the rotation of the rotating shaft 802 drives the sleeve ring 801 to rotate synchronously, and the rotation of the sleeve ring 801 drives the silo 9 and the bottom cylinder 10 to rotate synchronously, thereby dumping the material in the silo 9, thereby realizing the drying process of the material.
