Description

Technical Field

[0001] This invention relates to the field of fluidized bed technology, specifically to a distributed vibrating fluidized bed. Background Technology

[0002] Distributed vibrating fluidized beds are gas-solid treatment devices that combine mechanical vibration and airflow fluidization. The most common type is the vibrating fluidized bed dryer. It adds vibration excitation to a conventional fluidized bed, placing the material on a distribution plate with micropores. Hot airflow passes upwards from the bottom of the distribution plate, drying the powder particles larger than the micropores. The powder is distributed on the plate, and the vibration and hot air work together to fluidize the particles and transport them to the next process. However, the powder entering the fluidized bed through the feed pipe already contains moisture and needs drying, making it prone to caking into lumps. These lumps are not only difficult to dry, but also considered substandard when transported to the next process, affecting subsequent production. Existing mechanisms add a spiral feeding mechanism to the feed tank, but this only ensures smooth feeding and cannot pulverize the lumps, still affecting drying and subsequent processes. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides a distributed vibrating fluidized bed, employing the following technical solution:

[0004] The device includes a fully enclosed shell with a distribution plate fixedly connected inside. The distribution plate divides the interior of the shell into a material hopper and an air chamber arranged vertically. The upper part of the material hopper is connected to a feed hose, and the left side of the material hopper has a discharge port. The right side of the air chamber is connected to an air inlet pipe. Ear plates and vibration motors are fixedly connected to both sides of the shell. An elastic mechanism is set at the bottom of the ear plates. A base is set on the lower side of the shell, and the upper part of the base is connected to the bottom of the elastic mechanism. Several crushing mechanisms are set inside the material hopper. The lower part of the crushing mechanism moves through the distribution plate and the bottom of the shell and is fixedly connected to the base.

[0005] Furthermore, the crushing mechanism includes a set of fixed plates fixed on the distribution plate, a back plate fixedly connected to one side of the fixed plate, a set of rotating shafts fixedly connected to the back plate, a clamping plate rotatably connected to the rotating shafts, the clamping plate being located on the upper side of the distribution plate, a limiting ring located on the outer side of the clamping plate being fixedly connected to the rotating shaft, a spring a fixedly connected between the fixed plate and the clamping plate, and a limiting member located between the two clamping plates and abutting against the clamping plates.

[0006] Furthermore, the limiting component includes a wedge-shaped plate located between the two clamping plates and abutting against the clamping plates. A vertical plate is fixedly connected to the bottom of the wedge-shaped plate. The vertical plate is movable and sealably penetrates the distribution plate and the bottom of the housing. The bottom of the vertical plate is fixedly connected to the base.

[0007] Furthermore, the crushing mechanism is arranged in multiple alternating rows on the distribution plate.

[0008] Furthermore, the discharge port is connected to one of the following: a hose, a guide pipe, or a receiving box.

[0009] Furthermore, an exhaust hose is connected to the upper part of the casing.

[0010] Furthermore, the elastic mechanism includes an upper spring shaft fixed to the bottom of the ear plate and a lower spring shaft fixed to the base. Springs b are sleeved on the upper and lower spring shafts, and the upper and lower ends of springs b are fixedly connected to the bottom of the ear plate and the upper part of the base, respectively.

[0011] This invention has the following advantages: When the vibrating motor drives the entire fluidized bed to vibrate up and down, the upper part of the crushing mechanism also moves up and down, causing the lower part of the crushing mechanism to drive the upper part to perform a crushing action. When the powder enters the fluidized bed from top to bottom through the feed hose, the powder is scattered and crushed by the crushing mechanism that performs the crushing action, causing the lumps in the powder to be crushed. Then, it is dried by the upward hot airflow. This invention can also crush the lumps in the powder when the fluidized bed is vibrating and discharging, so that the lumps can reach the standard of powder. At the same time, the crushing and dispersing of the lumps improves the drying efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figure 1-5 This invention provides a distributed vibrating fluidized bed, comprising a shell 1 with an overall closed structure. A distribution plate 2 is fixedly connected inside the shell 1. The surface of the distribution plate 2 has micropores, allowing hot air to be sprayed upward through the bottom of the distribution plate 2 to dry the powder on the upper part of the distribution plate 2. The distribution plate 2 divides the interior of the shell 1 into a material hopper 3 and an air hopper 4 arranged vertically. After the hot air enters the air hopper 4, it enters the material hopper 3 through the distribution plate 2. The powder enters the material hopper 3 through a feed hose 5. The material hopper 3 is connected to the upper part of the feed hose 5. A discharge port 6 is opened on the left side of the material hopper 3. An air inlet pipe 7 is connected to the right side of the air hopper 4. Ear plates 8 and a vibration motor 9 are fixedly connected to both sides of the shell 1. An elastic mechanism is provided at the bottom of the ear plates 8. The vibration motor 9 drives the shell 1 to vibrate up and down. The shell drives the elastic mechanism to compress or rebound. At the same time, through the vibration of the elastic mechanism, the powder is evenly distributed on the distribution plate 2 and moves to the left, so that it is discharged through the discharge port 6. This is the prior art, and will be briefly described here.

[0020] A base 10 is provided on the lower side of the shell 1. The upper part of the base 10 is connected to the bottom of the elastic mechanism. Several crushing mechanisms are provided in the hopper 3. The lower part of the crushing mechanism moves through the distribution plate 2 and the bottom of the shell 1 and is fixedly connected to the base 10. The upper part of the crushing mechanism moves up and down with the distribution plate 2, and the lower part is fixed on the base 10.

[0021] The crushing mechanism includes a set of fixed plates 11 fixed on the distribution plate 2. A back plate 12 is fixedly connected to one side of the fixed plate 11. The back plate 12 is fixed to the back of the fixed plates 11 on both sides. A set of rotating shafts 13 is fixedly connected to the back plate 12. A clamping plate 14 is rotatably connected to the rotating shafts 13. The two clamping plates 14 are mirror images of each other and are located on the upper side of the distribution plate 2. A limiting ring 15 located on the outer side of the clamping plate 14 is fixedly connected to the rotating shafts 13. The limiting ring 15 limits the clamping plate 14 to prevent it from detaching from the rotating shafts 13 when rotating on them. A spring a16 is fixedly connected between the fixed plate 11 and the clamping plate 14. The spring a16 presses the lower part of the clamping plate 14, causing the clamping plate 14 to rotate on the rotating shafts 13. The mechanism also includes a limiting member located between the two clamping plates 14 and abutting against them. The limiting member pushes the inner side of the clamping plate 14, causing the clamping plate 14 to perform a crushing action.

[0022] The limiting component includes a wedge plate 17 located between two clamping plates 14 and abutting against the clamping plates 14. The wedge plate 17 has a trapezoidal structure that is narrow at the top and wide at the bottom. A vertical plate 18 is fixedly connected to the bottom of the wedge plate 17. The vertical plate 18 moves and seals through the distribution plate 2 and the bottom of the housing 1. When the housing 1 drives the distribution plate 2 and the upper part of the crushing mechanism to move up and down, the bottom of the housing 1 and the distribution plate 2 move up and down in a sealed manner on the vertical plate 18. The bottom of the vertical plate 18 is fixedly connected to the base 10.

[0023] The crushing mechanism is arranged in multiple alternating rows on the distribution plate 2, which enables it to crush lumps in the powder over a larger area.

[0024] The discharge port 6 is connected to one of the following: a hose, a guide pipe, or a receiving box. When the dried powder is discharged through the discharge port 6, it enters one of the following: a hose, a guide pipe, or a receiving box, where it is either collected or sent directly to the next process.

[0025] The upper part of the housing 1 is connected to an exhaust hose 19. When the powder is heated and dried by the hot airflow, some water vapor will evaporate. The water vapor carries some powder through the exhaust hose 19 and is discharged. The exhaust hose is connected to the separator for further separation.

[0026] The elastic mechanism includes an upper spring shaft 20 fixed to the bottom of the ear plate 8 and a lower spring shaft 21 fixed to the base 10. A spring b22 is sleeved on the upper spring shaft 20 and the lower spring shaft 21. The upper and lower ends of the spring b22 are fixedly connected to the bottom of the ear plate 8 and the upper part of the base 10, respectively. When the vibration motor 9 drives the housing 1 to vibrate up and down, the housing 1 drives the spring b22 to compress or rebound.

[0027] Working principle:

[0028] When the vibration motor 9 is started, it drives the housing 1 to vibrate up and down. The housing 1 drives the distribution plate 2, the fixing plate 11, the back plate 12, and the clamping plate 14 to move up and down. The spring b22 is compressed or rebounds. During the up and down movement, the inner side of the clamping plate 14 abuts against the side of the wedge plate 17. Since the wedge plate 17 is a trapezoidal structure that is narrow at the top and wide at the bottom, the clamping plate 14 rotates on the rotating shaft 13. The bottom side of the clamping plate 14 is squeezed by the spring a16, thereby realizing the clamping action of the two opposing clamping plates 14. When the spring a16 is compressed or rebounded, the powder falls from the top to the bottom into the hopper 3 through the feed hose 5. During the fall, it is clamped by the clamping plate 14, which crushes the lumpy material in the powder and makes it fall onto the distribution plate 2. Under the vibration of the vibration motor 9, the distribution plate 2 spreads the powder evenly on its upper part and gradually moves to the left and is discharged through the discharge port 6. At the same time, hot air enters the air chamber 4 through the air inlet pipe 7, and then enters the hopper 3 from the bottom to the top through the distribution plate 2 to spray and dry the powder on the distribution plate 2.

[0029] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
