[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 3As shown, an embodiment of the utility model provides a fluidized bed device, including: a fluidized bed body 10, an auxiliary material discharge assembly and a vibration assembly. Among them, the fluidized bed body 10 has a feed channel 11 and a fluidizing chamber 12, the feed channel 11 is connected to the fluidizing chamber 12, and the feed channel 11 is located at the top of the fluidizing chamber 12. The auxiliary material discharge assembly has a rotating part 21, the rotating part 21 is rotatably arranged in the feed channel 11, and the rotating part 21 is used to assist in material discharge. The vibration assembly has a vibration plate 31, the vibration plate 31 is arranged in the fluidizing chamber 12, and is arranged close to the feed channel 11, the vibration plate 31 is located below the feed channel 11, the vibration plate 31 is used to vibrate the material falling on the vibration plate 31, so that the material falls evenly, and the water level setting of the vibration plate 31 can prevent the material from piling up and causing agglomeration after falling from the feed channel 11, thereby increasing the reaction contact area between the material and the bed layer.

[0028] By applying the technical solution of the utility model, a rotating part 21 is arranged in the feed channel 11 of the fluidized bed, which can drive the material to fall from the inside of the feed channel 11 into the fluidizing chamber 12 faster, and avoid the accumulation of materials in the feed channel 11, which causes the feed channel 11 to be blocked, thereby affecting the working efficiency of the fluidized bed. At the same time, a vibration plate 31 is also arranged inside the fluidizing chamber 12, and the vibration plate 31 is located below the feed channel 11. Through the above arrangement, the vibration plate 31 cooperates with the rotating part 21. When the material enters the feed channel 11, the rotating part 21 drives the material to rotate to avoid the feed channel 11 from being blocked, thereby increasing the falling rate of the material. Then the material falls onto the vibration plate 31, and the vibration plate 31 vibrates the material to make the material fall more evenly, so as to improve the feeding efficiency of the fluidized bed, thereby increasing the reaction rate of the fluidized bed.

[0029] Specifically, the rotating part 21 includes a first rotating shaft 211 and a plurality of scrapers 212. The plurality of scrapers 212 are arranged on the first rotating shaft 211 at intervals along the circumference of the first rotating shaft 211. The first rotating shaft 211 is rotatably arranged in the feed channel 11. The first rotating shaft 211 drives the scrapers 212 to rotate, so as to drive the material to fall from the feed channel 11 to the fluidizing chamber 12. Through the above design, by driving the first rotating shaft 211 to rotate, the scrapers 212 will be driven to rotate in the feed channel 11, so that the material in the feed channel 11 is stirred to avoid the accumulation of materials in the feed channel 11 and blockage, thereby affecting the feeding efficiency of the fluidized bed. In the present application, the scrapers 212 are set to be square, and there is no limit on the number of scrapers 212. It can disturb the material and prevent it from blocking the feed channel 11. In other embodiments of the present application, the scraper 212 may also be configured to be in other shapes such as a spiral or sawtooth shape, and wound around a rotating roller, and the rotating roller is fixedly connected to the first rotating shaft 211 .

[0030] Furthermore, the auxiliary unloading component also includes a driving motor 22 and a first transmission component. The driving motor 22 has a first driving end 221, one end of the first transmission component is drivingly connected to the rotating part 21, and the first driving end 221 is drivingly connected to the other end of the first transmission component. The driving motor 22 drives the rotating part 21 to rotate through the first transmission component. In this way, the driving motor 22 can adjust the rotation frequency of the first rotating shaft 211 through the first driving end 221, and then accurately adjust the rotation rate of the rotating part 21 according to the actual feeding situation, which saves manpower compared to manually driving the first rotating shaft 211. Through the setting of the first transmission component, the transmission of the power of the driving motor 22 can be realized, and the output speed of the first driving end 221 can be adjusted according to the installation of transmission components with different transmission ratios to adapt to the actual unloading situation of the fluidized bed.

[0031] In the present application, the vibration plate 31 has a connection end and a free end that are relatively arranged, and the vibration assembly also includes a mounting shaft 32 and a vibrating member 33. Among them, the mounting shaft 32 is arranged in the fluidizing chamber 12, and the connection end is rotatably arranged on the mounting shaft 32. The vibrating member 33 is located at the free end, and the vibrating member 33 is used to drive the vibration plate 31 to swing along the mounting shaft 32. Through the above arrangement, when the material falls from the feed channel 11 onto the vibration plate 31, the vibrating member 33 can vibrate the material. Since the vibrating member 33 is arranged at the free end of the vibration plate 31, the swing amplitude of the vibration plate 31 along the mounting shaft 32 is increased, thereby increasing the vibration amplitude of the material, avoiding the accumulation of the material on the surface of the vibration plate 31, and also improving the material discharge rate.

[0032] Furthermore, the driving motor 22 also has a second driving end 222, and the vibration assembly also includes a second transmission assembly, and the second driving end 222 is drivingly connected to one end of the second transmission assembly. The vibrating member 33 includes a second rotating shaft 331, and the second rotating shaft 331 is rotatably arranged in the fluidizing chamber 12 and is located below the free end, and the other end of the second transmission assembly is drivingly connected to the second rotating shaft 331. In this arrangement, the second rotating shaft 331 can support and limit the vibration plate 31, so as to prevent the vibration plate 31 from swinging too much around the mounting shaft 32, causing the material to be misguided, or even causing the material to return to the feed channel 11 again, collide with subsequent materials to cause the feed channel 11 to be blocked, or directly thrown out of the feed channel 11.

[0033] like Figure 4 and Figure 5As shown, the vibration assembly also includes a cam 332, which is arranged on the second rotating shaft 331, and the cam 332 rotates synchronously with the second rotating shaft 331. The cam 332 abuts against the bottom of the vibration plate 31, and the driving motor 22 drives the vibration plate 31 to vibrate through the second rotating shaft 331 and the cam 332. The cam 332 is arranged on the second rotating shaft 331 to drive the vibration plate 31 to vibrate. In this way, the overall structure of the cam is simple and compact, and the probability of the material being blocked at the free end of the vibration plate 31 or being blocked by the material entering the cam 332 from the gap at the bottom of the vibration plate 31 is low, and the cam 332 is easy to disassemble and repair, and the production cost is low. In other embodiments of the present application, the vibrator can also be directly arranged below the vibration plate 31 to vibrate the vibration plate 31. In the present application, the driving motor 22 is set as a dual-axis motor. In other embodiments of the present application, two motors can also be set to drive the first transmission assembly and the second transmission assembly respectively.

[0034] Specifically, the vibration plate 31 is provided with an extension protrusion 311, which is located on both sides of the free end. The second rotating shaft 331 is provided with two cams 332, which are arranged one by one with the extension protrusion 311. Such a design can ensure the uniformity of vibration of the vibration plate 31 and avoid the accumulation of materials in the part of the vibration plate 31 where the vibration is uneven. By setting the extension protrusion 311, it is possible to avoid excessive friction of the cam 332 on the vibration plate 31, thereby extending the service life of the vibration plate 31. At the same time, the extension protrusion 311 can also protect the cam 332, preventing the material from falling into the gap between the cam 332 and the second rotating shaft 331 to cause obstruction, thereby affecting the vibration effect of the cam 332 on the vibration plate 31.

[0035] Among them, the vibrating member 33 also includes an elastic member 333, one end of the elastic member 333 is connected to the free end, and the other end of the elastic member 333 is connected to the top of the fluidizing chamber 12. Through the above arrangement, the elastic member 333 can also support and limit the vibration plate 31. When the vibration plate 31 swings upward, the elastic member 333 is in a compressed state, so as to prevent the vibration plate 31 from swinging too much toward the feed channel 11 and ejecting the material from the feed channel 11. And the elastic member 333 can make the vibration plate 31 swing more continuously and gently, and prevent the vibration plate 31 from swinging irregularly and indirectly due to the rotation of the cam 332, so that the material falls more evenly and continuously, and the reaction rate of the fluidized bed is improved. In the present application, the elastic member 333 is set as a spring. In other embodiments, the elastic member 333 can be set as a rubber rope, an elastic rope or other elastic structure.

[0036] Furthermore, the vibration plate 31 is tiltedly arranged in the fluidizing chamber 12, and the connection end is higher than the free end. Through the above arrangement, the falling of the material can be guided, so that the material can naturally fall to the bed layer in the fluidized bed after falling on the vibration plate 31, avoiding the material from not being able to be scattered on the bed layer, resulting in material waste.

[0037] Specifically, the surface of the vibration plate 31 close to the feed channel 11 is provided with a plurality of guide grooves 312, which are arranged side by side, and the guide grooves 312 extend from the connection end to the free end, and the guide grooves 312 are used to guide the material. In this way, the material can be dropped into different guide grooves 312 to disperse the material, and the material can be prevented from accumulating in the same place and then falling in large pieces. Subsequently, the material can be relatively diffused and distributed at different positions of the bed layer in the fluidized bed to react, further increasing the contact area between the material and the bed layer, and improving the reaction rate of the material.

[0038] The first transmission assembly includes a first driving wheel 231, a first driven wheel 232 and a first chain 233. The first driving wheel 231 is connected to the first driving end 221, the first driven wheel 232 is connected to the rotating part 21, and the first chain 233 is arranged between the first driving wheel 231 and the first driven wheel 232. The second transmission assembly includes a second driving wheel 341, a second driven wheel 342 and a second chain 343. The second driving wheel 341 is connected to the second driving end 222, the second driven wheel 342 is connected to the second rotating shaft 331, and the second chain 343 is arranged between the second driving wheel 341 and the second driven wheel 342. Through the above arrangement, the first transmission assembly and the second transmission assembly are both arranged close to the outer wall of the fluidized bed device, without occupying additional space and without interfering with the operation of other components inside the fluidized bed, so that the replacement structure layout of the fluidized bed device is more reasonable, and the space utilization rate and the compactness of the device are improved. In addition, the matching structure of the transmission wheel and the chain is simple, which is convenient for maintenance and replacement. The transmission wheels of different sizes can be replaced at any time according to the actual feeding situation to ensure the feeding efficiency of the fluidized bed device. Among them, the inner diameter of the first driving wheel 231 is smaller than the inner diameter of the first driven wheel 232, so that the first driven wheel 232 can rotate more slowly, thereby causing the scraper 212 to rotate slowly, ensuring that the material falls more evenly in the feeding channel 11.

[0039] In other embodiments of the present application, the first transmission assembly includes a first driving wheel 231, a first driven wheel 232 and a first chain 233, the first driving wheel 231 is connected to the first drive end 221, the first driven wheel 232 is connected to the rotating part 21, and the first chain 233 is arranged between the first driving wheel 231 and the first driven wheel 232, and the transmission mode of the second transmission assembly is not limited. In another embodiment of the present application, the second transmission assembly includes a second driving wheel 341, a second driven wheel 342 and a second chain 343, the second driving wheel 341 is connected to the second drive end 222, the second driven wheel 342 is connected to the second rotating shaft 331, and the second chain 343 is arranged between the second driving wheel 341 and the second driven wheel 342. The transmission mode of the first transmission assembly is not limited, and it can be other transmission modes such as gear meshing or belt transmission.

[0040] Specifically, when the fluidized bed device provided in the present application is used to discharge materials, the operating steps are as follows: when the material is introduced from the feed channel 11 at the top of the fluidized bed body 10, the drive motor 22 is started to drive the first driving wheel 231 of the first driving end 221 to rotate, the first driving wheel 231 rotates through the first chain 233 to drive the first driven wheel 232 to rotate, the first driven wheel 232 rotates to drive the first rotating shaft 211 to rotate, the first rotating shaft 211 rotates to drive the scraper 212 to rotate in the feed channel 11, thereby effectively avoiding the accumulation of materials in the feed channel 11 and achieving uniform feeding. At the same time, the driving motor 22 rotates to drive the second driving wheel 341 of the second driving end 222 to rotate, and the second driving wheel 341 drives the second driven wheel 342 to rotate through the second chain 343. The second driven wheel 342 rotates to drive the mounting shaft 32 to rotate, and then drives the two cams 332 to rotate, so that the vibration plate 31 vibrates up and down, thereby preventing materials from accumulating in the guide groove 312. Through the guide groove 312 on the vibration plate 31, the materials can be relatively diffused and distributed in the fluidized bed body 10, thereby improving the discharge rate of the fluidized bed, thereby greatly improving the reaction efficiency of the fluidized bed.
