Description

Technical Field

[0001] This utility model relates to the field of drying machinery technology, and in particular to a high-efficiency vibrating fluidized bed. Background Technology

[0002] High-efficiency vibrating fluidized bed is an improved fluidized bed technology. It uses a vibrating device to vibrate the fluidized bed to enhance the flowability and mass and heat transfer of particulate materials. High-efficiency vibrating fluidized bed has wide applications in chemical, pharmaceutical, food, and environmental protection fields, such as in the drying, crystallization, adsorption, and catalysis of particulate materials. It can improve production efficiency, reduce energy consumption, and improve product quality, and has significant economic and environmental benefits.

[0003] The prior art discloses a patent application (CN202322079831.X) entitled "A High-Efficiency Vibrating Fluidized Bed." This application addresses the issue that existing vibrating fluidized beds require regular cleaning of the vibrating plates. During vibration, particulate materials may adhere to the vibrating plates, forming particle accumulation and adhesion, affecting the vibration effect and fluidized bed performance. Currently, cleaning the vibrating plates mostly relies on manual labor, which undoubtedly increases the labor intensity of workers and reduces their work efficiency. Furthermore, materials are prone to clumping before drying. Directly pouring these clumped materials into the vibrating fluidized bed prevents timely and uniform vibration distribution, and clumping may lead to poor material flowability, affecting the normal operation of the vibrating fluidized bed and the material pouring effect, resulting in uneven drying. The proposed solution eliminates the need for manual cleaning of the vibrating conveyor plate using a scraper, reducing labor intensity and effectively improving work efficiency. Simultaneously, the ultrasonic vibrating plate dries and disperses the material inside the discharge hopper, further improving work efficiency.

[0004] However, in actual use, the above-mentioned application has a relatively complex structure due to the need for the ultrasonic vibrating plate to work with an ultrasonic generator and to pass a high voltage current, resulting in high production and maintenance costs. At the same time, the material tends to aggregate inside the discharge bucket, leading to low heating efficiency and uniformity. The aggregated material also affects the dispersion efficiency, thus impacting work efficiency. Further improvements are needed. Additionally, the application uses a fan for fluidization, but the fan speed is limited, which restricts work efficiency. Furthermore, the large number of fans required for the airflow to pass through multiple layers of clinker plates before acting on the material also affects work efficiency. Further improvements are also needed. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a high-efficiency vibrating fluidized bed.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency vibrating fluidized bed, comprising an upper box and a lower bed, wherein the upper box is fixedly mounted on the top surface of the lower bed, and a first drive roller is rotatably connected inside the upper box, and a first conveyor belt is sleeved on the outside of the first drive roller, a first vibration structure is installed on the inside of the first conveyor belt, and a ceramic heating plate is fixedly mounted on the top surface of the upper box above the first conveyor belt, a second drive roller is rotatably connected inside the lower bed, and a second conveyor belt is sleeved on the outside of the second drive roller, and a second vibration structure is installed inside the second conveyor belt, a blowpipe is mounted between the second vibration structures on the inside of the second conveyor belt, and an air outlet is connected through the surface of the blowpipe, a hot air fan is fixedly mounted on the back side of the lower bed, and a diverter pipe is connected through the output end of the hot air fan, and the diverter pipe is connected through the blowpipe, and the bottom surface of one end of the upper box is connected through the material guide channel to the top surface of one end of the lower bed.

[0007] By adopting the above technical solution, when the material passes under the ceramic heating plate, it is heated by the thermal radiation of the ceramic heating plate for preliminary drying. Simultaneously, the first vibration structure operates, and the rotating striking ball strikes the first conveyor belt, causing the conveyor belt to vibrate at high frequency. This vibration disperses the material, improving the efficiency and uniformity of subsequent fluidized drying. The material on the top surface of the first conveyor belt is evenly spread out by the vibration, resulting in good preliminary drying and vibration crushing effects. Furthermore, this solution avoids the problems of high power consumption, complex structure, and high maintenance and production costs associated with ultrasonic vibration, improving ease of use and making it more energy-efficient and environmentally friendly. Additionally, after preliminary drying... The material falls onto the top surface of the second conveyor belt through the material conveying channel. The second vibration structure drives the top surface of the second conveyor belt to generate high-frequency vibration, which further improves the material turning efficiency, the uniformity of fluidized drying, and the working efficiency. In addition, the width of the top opening of the air outlet is smaller than the width of the bottom opening of the air outlet. During fluidized drying, the hot air generated by the hot air blower enters the blowpipe through the diverter pipe. The hot airflow is accelerated after passing through the top opening of the air outlet and then blown out, which increases the airflow speed and thus improves the fluidization efficiency. At the same time, the blowpipe is located between the second conveyor belts, and the hot airflow only needs to pass through a single layer of the second conveyor belt to carry out the drying work, which further improves the working efficiency.

[0008] Furthermore, the first vibration structure and the second vibration structure are identical, and the first vibration structure includes a rotating rod, a connecting spring, and a striking ball, with the striking ball connected to the rotating rod via the connecting spring.

[0009] By adopting the above technical solution, the surface of the striking ball is polished to reduce wear, and the first and second vibration structures with the same structure are easy to produce and install.

[0010] Furthermore, a third drive motor is fixedly installed on the front face of both the upper housing and the lower bed, and the output end of the third drive motor is fixedly connected to one end of the rotating rod.

[0011] By adopting the above technical solution, the two ends of the rotating rod are rotatably connected to the upper box and the lower bed through bearings, which improves the stability of rotation. The number of third drive motors is the same as the number of rotating rods.

[0012] Furthermore, the first vibration structure and the second vibration structure are arranged in multiple sets at equal intervals, the striking balls are arranged in multiple sets at equal intervals along the length of the rotating rod, and the striking balls are arranged in multiple sets at equal angles along the central axis of the rotating rod.

[0013] By adopting the above technical solution, the increased number of hitting balls improves the vibration effect and increases work efficiency.

[0014] Furthermore, the two ends of the connecting spring are fixedly connected to the surface of the rotating rod and the surface of the striking ball, respectively, and the number of connecting springs is equal to the number of striking balls.

[0015] By adopting the above technical solution, the connecting spring is made of manganese steel, which is more durable and reliable.

[0016] Furthermore, a feed inlet is provided on the top surface of the other end of the upper box body, and a discharge outlet is provided on the bottom surface of the other end of the lower bed body.

[0017] By adopting the above technical solution, the feed inlet is convenient for feeding materials, and the discharge outlet is convenient for discharging materials.

[0018] Furthermore, a first drive motor is fixedly installed on the front of the upper housing, and the output end of the first drive motor is fixedly connected to the mounting end of the first drive roller.

[0019] By adopting the above technical solution, the first drive roller is rotatably connected to the upper housing via a roller shaft, and the roller shaft is fixedly connected to the output end of the first drive motor.

[0020] Furthermore, a second drive motor is fixedly installed on the front face of the lower bed, and the output end of the second drive motor is fixedly connected to the mounting end of the second drive roller.

[0021] By adopting the above technical solution, the second drive roller is rotatably connected to the upper housing via a roller shaft, and the roller shaft is fixedly connected to the output end of the second drive motor.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. In this application, a first vibration structure and an upper box are adopted. The material is fed into the upper box through the feed inlet. The first drive motor drives the first drive roller to rotate, which drives the first conveyor belt to transport the material. When the material passes under the ceramic heating plate, it is heated by the thermal radiation of the ceramic heating plate for preliminary drying. At the same time, the first vibration structure operates. The rotating rod of the first vibration structure rotates under the drive of the third drive motor, which drives the striking ball to rotate and strike the first conveyor belt, thereby generating high-frequency vibration of the first conveyor belt. By vibrating and dispersing the material, the efficiency and uniformity of the subsequent fluidized drying are improved. The material on the top surface of the first conveyor belt is evenly spread out by vibration, resulting in good preliminary drying effect and good vibration crushing effect. At the same time, it avoids the problems of high power consumption, complex structure, and high maintenance and production costs of ultrasonic vibration, improves the convenience of use, and is more energy-saving and environmentally friendly.

[0024] 2. In this application, a second vibration structure is adopted. The rotating rod in the second vibration structure is also driven by the third drive motor to rotate, which drives the striking ball to rotate and strike the second conveyor belt. The material that has been preliminarily dried falls onto the top surface of the second conveyor belt through the material channel. The second drive motor drives the second drive roller to rotate, which drives the second conveyor belt to perform conveying operation. The second vibration structure causes the top surface of the second conveyor belt to generate high-frequency vibration, which further improves the material turning efficiency and improves the uniformity and working efficiency of fluidized drying.

[0025] 3. In this application, a blowpipe and an air outlet are used. The width of the top opening of the air outlet is smaller than the width of the bottom opening of the air outlet. During fluidized drying, the hot air blower generates hot air, which enters the blowpipe through the diversion pipe. The hot airflow is accelerated after passing through the top opening of the air outlet and then blown out, which increases the airflow speed and thus improves the fluidization efficiency. At the same time, the blowpipe is located between the second conveyor belts, and the hot airflow only needs to pass through a single layer of the second conveyor belt to carry out the drying work, which further improves the work efficiency.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-4 As shown in the embodiment of this application, a high-efficiency vibrating fluidized bed is disclosed, including an upper box body 1 and a lower bed body 2. The upper box body 1 is fixedly mounted on the top surface of the lower bed body 2, and a first drive roller 3 is rotatably connected inside the upper box body 1. A first conveyor belt 4 is sleeved on the outside of the first drive roller 3, and a first vibration structure 6 is installed on the inside of the first conveyor belt 4. A ceramic heating plate 8 is fixedly mounted on the top surface of the upper box body 1 above the first conveyor belt 4. A second drive roller 11 is rotatably connected inside the lower bed body 2. A second conveyor belt 5 is sleeved on the outside of the 11, and a second vibration structure 7 is installed inside the second conveyor belt 5. A blow pipe 9 is installed between the second vibration structures 7 on the inside of the second conveyor belt 5, and an air outlet 10 is connected through the surface of the blow pipe 9. A hot air fan 22 is fixedly installed on the back of the lower bed 2, and a diversion pipe 21 is connected through the output end of the hot air fan 22. The diversion pipe 21 is connected through the blow pipe 9. The bottom surface of one end of the upper box 1 is connected through the material conveying channel 14 to the top surface of one end of the lower bed 2.

[0033] When the material passes under the ceramic heating plate 8, it is heated by the thermal radiation of the ceramic heating plate 8 for preliminary drying. At the same time, the first vibration structure 6 operates, and the striking ball 20 rotates, striking the first conveyor belt 4, thereby generating high-frequency vibration of the first conveyor belt 4. The material is dispersed by vibration, which improves the efficiency and uniformity of subsequent fluidized drying. The material on the top surface of the first conveyor belt 4 is evenly spread out by vibration, resulting in good preliminary drying and vibration crushing effects. At the same time, it avoids the problems of high power consumption, complex structure, and high maintenance and production costs of ultrasonic vibration, improving the convenience of use and making it more energy-saving and environmentally friendly.

[0034] Meanwhile, the pre-dried material falls onto the top surface of the second conveyor belt 5 through the material conveying channel 14. The second vibration structure 7 drives the top surface of the second conveyor belt 5 to generate high-frequency vibration, which further improves the material turning efficiency, the uniformity of fluidized drying, and the working efficiency. In addition, the top opening width of the air outlet 10 is smaller than the bottom opening width of the air outlet 10. During fluidized drying, the hot air blower 22 generates hot air, which enters the blow pipe 9 through the diversion pipe 21. The hot airflow is accelerated through the top opening of the air outlet 10 and then blown out, which increases the airflow speed and thus improves the fluidization efficiency.

[0035] Meanwhile, the blowpipe 9 is located between the second conveyor belts 5, and the hot airflow only needs to pass through a single layer of the second conveyor belt 5 to carry out the drying work, which further improves the work efficiency.

[0036] The first vibration structure 6 and the second vibration structure 7 are identical. The first vibration structure 6 includes a rotating rod 18, a connecting spring 19, and a striking ball 20. The striking ball 20 is connected to the rotating rod 18 via the connecting spring 19.

[0037] It should be noted that the surface of the striking ball 20 is polished to reduce wear, and the first vibration structure 6 and the second vibration structure 7, which have the same structure, are easy to manufacture and install.

[0038] It should be noted that a third drive motor 17 is fixedly installed on the front face of both the upper housing 1 and the lower bed 2, and the output end of the third drive motor 17 is fixedly connected to one end of the rotating rod 18. The two ends of the rotating rod 18 are rotatably connected to the upper housing 1 and the lower bed 2 through bearings to improve the stability of rotation. The number of third drive motors 17 is the same as the number of rotating rods 18.

[0039] Multiple sets of the first vibration structure 6 and the second vibration structure 7 are arranged at equal intervals. Multiple sets of striking balls 20 are also arranged at equal intervals along the length of the rotating rod 18, and multiple sets of striking balls 20 are arranged at equal angles along the central axis of the rotating rod 18. The large number of striking balls 20 improves the vibration effect and increases work efficiency.

[0040] The two ends of the connecting spring 19 are fixedly connected to the surface of the rotating rod 18 and the surface of the striking ball 20, respectively, and the number of connecting springs 19 is equal to the number of striking balls 20. The connecting springs 19 are made of manganese steel, which is more durable and reliable.

[0041] The upper chamber 1 has a feed inlet 12 on the top surface at the other end, and the lower chamber 2 has a discharge outlet 13 on the bottom surface at the other end. The feed inlet 12 facilitates feeding, and the discharge outlet 13 facilitates discharging.

[0042] A first drive motor 15 is fixedly installed on the front of the upper housing 1, and the output end of the first drive motor 15 is fixedly connected to the mounting end of the first drive roller 3. The first drive roller 3 is rotatably connected to the upper housing 1 through a roller shaft, and the roller shaft is fixedly connected to the output end of the first drive motor 15.

[0043] A second drive motor 16 is fixedly installed on the front face of the lower bed 2, and the output end of the second drive motor 16 is fixedly connected to the mounting end of the second drive roller 11. The second drive roller 11 is rotatably connected to the upper housing 1 through a roller shaft, and the roller shaft is fixedly connected to the output end of the second drive motor 16.

[0044] The working principle of a high-efficiency vibrating fluidized bed in this embodiment is as follows: the material is fed into the upper box 1 through the feed port 12, the first drive motor 15 drives the first drive roller 3 to rotate, and drives the first conveyor belt 4 to transport the material. When the material passes under the ceramic heating plate 8, it is heated by the thermal radiation of the ceramic heating plate 8 and undergoes preliminary drying.

[0045] Simultaneously, the first vibration structure 6 operates, and the rotating rod 18 of the first vibration structure 6 rotates under the drive of the third drive motor 17, driving the striking ball 20 to rotate and strike the first conveyor belt 4, thereby generating high-frequency vibration of the first conveyor belt 4. By vibrating and dispersing the material, the efficiency and uniformity of the subsequent fluidized drying are improved. The material on the top surface of the first conveyor belt 4 is evenly spread out by vibration, resulting in good initial drying effect and good vibration crushing effect. At the same time, it avoids the problems of high power consumption, complex structure, and high maintenance and production costs of ultrasonic vibration, improves the convenience of use, and is more energy-saving and environmentally friendly.

[0046] The rotating rod 18 in the second vibration structure 7 also rotates under the drive of the third drive motor 17, which drives the striking ball 20 to rotate and strike the second conveyor belt 5. The material that has been preliminarily dried falls onto the top surface of the second conveyor belt 5 through the material channel 14. The second drive motor 16 drives the second drive roller 11 to rotate, which drives the second conveyor belt 5 to perform conveying operation. The second vibration structure 7 drives the top surface of the second conveyor belt 5 to generate high-frequency vibration, which further improves the material turning efficiency and improves the uniformity and working efficiency of fluidized drying.

[0047] In addition, the top opening width of the air outlet 10 is smaller than the bottom opening width of the air outlet 10. During fluidized drying, the hot air blower 22 generates hot air, which enters the blowpipe 9 through the diversion pipe 21. The hot airflow is accelerated after passing through the top opening of the air outlet 10 and then blown out, which increases the airflow speed and thus improves the fluidization efficiency. At the same time, the blowpipe 9 is located between the second conveyor belts 5, so the hot airflow only needs to pass through a single layer of the second conveyor belt 5 to carry out the drying work, which further improves the work efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
