Description

Technical Field

[0001] This invention relates to the field of fluidized beds, and particularly to vibrating fluidized beds. Background Technology

[0002] Vibrating fluidized beds are drying, cooling, and granulation equipment widely used in the chemical, pharmaceutical, and food industries. By inputting hot air into the fluidized bed, solid particles are fluidized under the action of airflow. At the same time, mechanical vibration is used to reduce the adhesion between particles, promote uniform fluidization, and realize the directional conveying of materials. It is widely used in various processing applications.

[0003] However, in traditional vibrating fluidized beds, the mixing and breaking action relies primarily on the random collisions and vibrational throwing of particles in a suspended airflow state. For materials with high initial moisture content and strong adhesion, this passive force is often insufficient to effectively and promptly disperse stubborn agglomerates formed during fluidization. Undispersed agglomerates exhibit high resistance to heat and mass transfer, leading to uneven drying, reduced efficiency, and even affecting the quality of the final product. Furthermore, the internal structure of the equipment is usually fixed, making it difficult to flexibly adjust the action of moving components and the volume of the upper processing space when handling materials with different properties or at different processing stages. This hinders the optimal matching of process parameters, leaving room for improvement in equipment adaptability and energy efficiency. Additionally, the hot and humid airflow rising from the bed is typically discharged directly after leaving the material zone. This airflow still carries considerable heat energy and may entrain a large number of insufficiently dried fine particles. Existing designs lack effective guidance and reuse mechanisms for this airflow and particles, potentially leading to heat waste, product yield loss, and increased load on subsequent dust removal systems.

The reciprocating screw is movably installed between the top bracket and the bottom bracket. The driven gear is fixedly installed at the lower end of the reciprocating screw. The transmission rod is movably installed on one side of the exhaust pipe and located above the bottom bracket. Two transmission bevel gears are welded to both ends of the transmission rod. The fan frame is fixedly installed on the inner wall of the exhaust pipe. The fan blades are rotatably installed inside the fan frame. The drive gear is fixedly installed on the upper end of the fan blade shaft. The lifting block is fitted and installed outside the reciprocating screw.

[0008] As a further embodiment of the present invention, the transmission rod extends into the exhaust pipe, and the two transmission bevel teeth are respectively meshed with the drive gear and the driven gear, and the lifting connecting plate is fixedly installed on one side of the lifting block.

[0009] As a further embodiment of the present invention, the adjustment structure includes an adjustment rod, an adjustment gear, a gear rod, a transmission bevel gear, and a rod body bevel gear. The adjustment rod is movably installed inside the lifting guide rod, the adjustment gear is fixedly installed at the lower end of the adjustment rod, the gear rod is movably installed inside the blade mounting rod, multiple transmission bevel gears are fixedly installed on the outer side of the blade mounting rod, and multiple rod body bevel gears are movably installed on the inner wall of the blade mounting rod.

[0010] As a further embodiment of the present invention, the lifting guide rod and the blade mounting rod are internally connected, the adjusting gear is located inside the blade mounting rod, the transmission bevel teeth at the end of the blade mounting rod are meshed with the adjusting gear, multiple transmission bevel teeth are meshed with multiple rod bevel teeth, and the rod bevel teeth penetrate the blade mounting rod and are fixedly connected to the blade rod.

[0011] As a further embodiment of the present invention, the active lifting structure includes a lifting machine, a drive motor, a lead screw sleeve, and a lifting lead screw. The lifting machine is fixedly installed on the upper end of the fluidized bed top cover, the drive motor is fixedly installed on the front end of the lifting machine, the lead screw sleeve is fixedly installed on the upper end of the lifting machine, and the lifting lead screw is threadedly installed on the bottom of the lifting machine.

[0012] As a further embodiment of the present invention, the lifting screw extends through the interior of the fluidized bed top cover, and the lower pressure plate is fixedly installed at the lower end of the lifting screw.

[0013] As a further embodiment of the present invention, multiple reinforcing rods are fixedly installed on the inner wall of the fluidized bed body above the fluidized processing mesh plate, and the lower pressure plate, blade rod and contact blade are located above the fluidized processing mesh plate.

[0014] As a further embodiment of the present invention, the discharge box and the feed hopper are both connected to the interior of the fluidized bed body and the fluidized bed top cover, and a discharge pipe is fixedly installed at the lower end of the discharge box.

[0015] As a further embodiment of the present invention, spring foot pads are fixedly installed at the four lower corners of the fluidized bed body, and multiple observation windows penetrating the shell are provided at the front end of the fluidized bed body on both sides of the vibrating motor.

[0016] Compared with existing technologies, this invention has the following advantages: By using a synchronous lifting structure installed in the exhaust pipe, the kinetic energy of the fluidized bed's own exhaust airflow drives the fan blades to rotate. Then, through a gear and screw mechanism, the kinetic energy of the airflow is converted into the continuous lifting motion of the blade rod and contact blades. This process requires no additional power source and can automatically and cyclically mechanically impact and stir the thrown material particles, effectively enhancing particle crushing, mixing, and surface renewal. The automatic impact effectively breaks up the adhesion and agglomeration between wet material particles, increases the contact area between particles and hot air, strengthens the heat and mass transfer process, and improves the uniformity and efficiency of drying or reaction, making it particularly suitable for easily agglomerated materials.

[0017] By manually rotating the adjusting rod, and then adjusting the gears, gear rods, transmission bevel teeth and rod body bevel teeth to change the unfolding angle of all blade rods, the contact blades can be adjusted. This allows for adjustment of the contact area and action mode between the contact blades and material particles, thus enabling flexible adaptation to the processing needs of materials with different properties and optimizing the impact effect.

[0018] The active lifting structure controlled by a drive motor allows for proactive adjustment of the height of the lower pressure plate inside the fluidized bed. As the lower pressure plate descends, it directly reduces the free space volume inside the fluidized bed's top cover. The absorbent strips at the bottom of the lower pressure plate contact the thrown particles, directly absorbing some of the moisture from their surface, providing a buffering and auxiliary dehumidification effect. The adjustable volume design allows the equipment to better match the needs of different feed rates or processing stages, helping to maintain suitable airflow velocity and fluidization state, improving equipment adaptability and processing efficiency. After the lower pressure plate and the parallel contact blades move downwards, they form a more complex mechanical structure above the bed. The rising hot airflow at the bottom changes direction upon contact with these surfaces, creating impact, turbulence, and downward rebound. This rebounding airflow mixes with the continuously rising mainstream airflow, forming stronger turbulence and gas recirculation above the bed. This helps to disperse the humid and hot air that may accumulate at the top, making the temperature distribution within the bed more uniform. The heat and volatile components carried by the rebounding airflow have more opportunities to re-contact falling or fluidizing material particles, improving thermal energy utilization and mass transfer efficiency. The changed airflow direction helps to slow down and settle some of the fine particles entrained by the airflow, returning them to the fluidized bed, reducing material loss and pressure on the subsequent dust removal system.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1-9 As shown, please refer to the vibrating fluidized bed diagram. Figures 1-9 The fluidized bed includes a fluidized bed body 1, a fluidized bed top cover 2 fixedly installed at the upper end of the fluidized bed body 1, a vibration motor 4 fixedly installed at the center of the front end of the fluidized bed body 1, multiple air inlet pipes 6 fixedly installed at the rear end of the fluidized bed body 1, a discharge box 7 fixedly installed on one side of the fluidized bed body 1 and the fluidized bed top cover 2, a feed hopper 9 fixedly installed on the other side of the fluidized bed top cover 2, a fluidized bed processing screen 10 fixedly installed inside the fluidized bed body 1, multiple exhaust pipes 12 fixedly installed at the upper end of the fluidized bed top cover 2, a synchronous lifting structure 13 provided on one side of the interior of the exhaust pipes 12, and a fixed installation on one side of the synchronous lifting structure 13. There is a lifting connecting plate 24. A lifting guide rod 25 that penetrates the top cover 2 of the fluidized bed is fixedly installed at the lower end of the lifting connecting plate 24. A blade mounting rod 26 is welded to the lower end of the lifting guide rod 25. Multiple blade rods 27 are movably installed on the outside of the blade mounting rod 26. Contact blades 28 are welded to the outside of the blade rods 27. An adjustment structure 29 is provided inside the lifting guide rod 25 and the blade mounting rod 26. An active lifting structure 41 is fixedly installed on the upper end of the fluidized bed body 1 on one side of the exhaust pipe 12. A lower pressure plate 39 is fixedly installed at the lower end of the active lifting structure 41. Multiple absorbent cotton strips 40 are fixedly installed at the lower end of the lower pressure plate 39.

[0031] Specifically, material is fed into the fluidized bed body 1 and fluidized bed top cover 2 through the feed hopper 9 and falls onto the fluidized processing screen 10. Hot air is introduced through the air inlet pipe 6 and through the porous distribution plate at the bottom of the fluidized processing screen 10. When the airflow velocity reaches a certain value, the solid particles on the fluidized processing screen 10 are blown up and are in a suspended fluidized state, allowing the particles to fully contact the gas. The operation of the vibration motor 4 generates directional mechanical vibration, which effectively breaks the adhesion between the material particles. At the same time, the vibration gives the particles a directional, parabolic throwing motion, causing the material to move to the discharge box 7 for discharge.

[0032] Please refer to this carefully. Figures 4-5 The synchronous lifting structure 13 includes a top support 14, a bottom support 15, a reciprocating screw 16, a driven gear 17, a transmission rod 18, a transmission bevel gear 19, a fan frame 20, a fan blade 21, a drive gear 22, and a lifting block 23. The top support 14 and the bottom support 15 are both fixedly installed on one side of the exhaust pipe 12, with the top support 14 located above the bottom support 15. The reciprocating screw 16 is movably installed between the top support 14 and the bottom support 15. The driven gear 17 is fixedly installed at the lower end of the reciprocating screw 16. The transmission rod 18 is movably installed on one side of the exhaust pipe 12 and located above the bottom support 15. Two transmission bevel gears 19 are welded to both ends of the transmission rod 18. The fan frame 20 is fixedly installed on the inner wall of the exhaust pipe 12. The fan blade 21 is rotatably installed inside the fan frame 20. The drive gear 22 is fixedly installed on the upper end of the shaft of the fan blade 21. The lifting block 23 is fitted and installed on the outside of the reciprocating screw 16.

[0033] Please refer to this carefully. Figures 4-5 The transmission rod 18 extends into the exhaust pipe 12, and the two transmission bevel teeth 19 are respectively meshed with the drive gear 22 and the driven gear 17. The lifting connecting plate 24 is fixedly installed on one side of the lifting block 23.

[0034] Specifically, the exhaust pipe 12 discharges air from the fluidized bed top cover 2. When the air passes through the exhaust pipe 12, it blows the fan blades 21 to rotate. The rotation of the fan blades 21 drives the driven gear 17 to rotate through the drive gear 22, the transmission bevel gear 19 and the transmission rod 18, thereby driving the reciprocating screw 16 to rotate. Then, the rotation of the reciprocating screw 16 drives the lifting block 23 to move up and down in a circular motion. Then, through the connection of the lifting connecting plate 24, the lifting guide rod 25 and the blade mounting rod 26, the blade rod 27 and the contact blade 28 are continuously lifted and lowered inside the fluidized bed top cover 2, increasing the active mechanical crushing and stirring function of the material particles.

[0035] Please refer to this carefully. Figures 6-7The adjustment structure 29 includes an adjustment rod 30, an adjustment gear 31, a gear rod 32, a transmission bevel gear 33, and a rod bevel gear 34. The adjustment rod 30 is movably installed inside the lifting guide rod 25. The adjustment gear 31 is fixedly installed at the lower end of the adjustment rod 30. The gear rod 32 is movably installed inside the blade mounting rod 26. Multiple transmission bevel gears 33 are fixedly installed on the outer side of the blade mounting rod 26. Multiple rod bevel gears 34 are movably installed on the inner wall of the blade mounting rod 26.

[0036] Please refer to this carefully. Figures 6-7 The lifting guide rod 25 is internally connected to the blade mounting rod 26. The adjusting gear 31 is located inside the blade mounting rod 26. The transmission bevel tooth 33 at the end of the blade mounting rod 26 is meshed with the adjusting gear 31. Multiple transmission bevel teeth 33 are meshed with multiple rod bevel teeth 34. The rod bevel teeth 34 penetrate the blade mounting rod 26 and are fixedly connected to the blade rod 27.

[0037] Specifically, the rotation of the adjusting rod 30 drives the adjusting gear 31 to rotate. The adjusting gear 31 drives the gear rod 32 to rotate through the transmission bevel teeth 33. Other transmission bevel teeth 33 on the gear rod 32 drive the rod body bevel teeth 34 to rotate. Therefore, the rod body bevel teeth 34 drive the blade mounting rod 26 to rotate, so that the blade rod 27 on the outside of the blade mounting rod 26 changes its angle. The blade rod 27 at different angles can change the contact area with the material particles.

[0038] Please refer to this carefully. Figures 8-9 The active lifting structure 41 includes a lifting platform 35, a drive motor 36, a lead screw sleeve 37, and a lifting lead screw 38.

[0039] Please refer to this carefully. Figures 8-9 The lifting screw 38 extends into the interior of the fluidized bed top cover 2, and the lower pressure plate 39 is fixedly installed at the lower end of the lifting screw 38.

[0040] Specifically, the operation of the drive motor 36 drives the lifting screw 38 at the bottom of the elevator 35 to lift and lower in a spiral motion. The lifting screw 38 then drives the lower pressure plate 39 to lift and lower, adjusting the height of the lower pressure plate 39 inside the fluidized bed top cover 2, thereby changing the volume inside the fluidized bed top cover 2. After the lower pressure plate 39 is lowered, the absorbent cotton strip 40 can also come into contact with the thrown material particles. The absorbent cotton strip 40 plays a role in absorbing moisture and buffering.

[0041] Please refer to this carefully. Figure 3Multiple reinforcing rods 11 are fixedly installed on the inner wall of the fluidized bed body 1 above the fluidized processing mesh plate 10.
