Description

Technical Field

[0001] This application relates to the technical field of fluidized bed equipment, and in particular to an internally heated vibrating fluidized bed. Background Technology

[0002] In modern industrial production, the drying and processing of materials is crucial. Vibrating fluidized beds, as a widely used drying device, play a key role in many industries such as chemical, food, and pharmaceutical due to their efficient heat and mass transfer performance. Traditional vibrating fluidized beds typically rely on external hot air for heat supply; however, this method has many drawbacks. On the one hand, heat loss is inevitable during the transmission of external hot air, leading to low energy efficiency and increased production costs. On the other hand, hot air is difficult to apply evenly to the material, resulting in uneven heating and incomplete drying of some materials, making it difficult to guarantee product quality. With continuous technological advancements, microwave technology, as a novel heating method, is gradually emerging in the drying field. Against this backdrop, the development of internally heated microwave multi-stage circulating fluidized beds has significant practical implications.

[0003] A search revealed Chinese patent publication number CN206387186U, which discloses an internally heated vibrating fluidized bed, including a wet scrubber. A second induced draft fan is installed at the bottom of the wet scrubber, and a first induced draft fan is installed at the top. A high-pressure water pipe interface is provided on the side of the wet scrubber, and a spray device is installed inside. An electrostatic dust collection device is located below the spray device, and a cyclone separator is located on one side of the wet scrubber. This invention features an inflatable and deflated shock-absorbing air cushion at the bottom, which can reduce bed vibration to a certain extent, protect the stability of internal components, and reduce maintenance costs. The wet scrubber and bed are connected via a cyclone separator. The overall structure is scientifically sound and efficient, with a smaller volume than traditional equipment for the same production capacity, resulting in lower operating load and energy consumption.

[0004] Although the aforementioned patents achieve smaller size, lower operating burden, and lower energy consumption compared to traditional equipment, the mixing effect of materials in the processing bed is poor. Traditional vibration methods are difficult to achieve sufficient tumbling and interleaving of materials, resulting in uneven mixing of materials with different properties, which affects the effect of subsequent processes. Furthermore, the problem of uneven drying is prominent. Due to the limitations of the heat transfer method, the degree of contact between the material and the heat source is inconsistent, resulting in uneven drying of materials, which cannot meet the requirements of high-quality production. Utility Model Content

[0005] The purpose of this application is to provide an internally heated vibrating fluidized bed, which aims to improve the problems of poor mixing effect, uneven drying, poor flow and insufficient equipment stability in the material processing process.

[0006] This application provides an internally heated vibrating fluidized bed with the following technical solution: An internally heated vibrating fluidized bed includes an operating frame, with placement openings fixedly connected to both sides of the top of the operating frame, and a support frame fixedly connected to the bottom of the operating frame. The operating frame contains a multi-stage circulation mechanism and a heating mechanism. The support frame contains a gas circulation mechanism. The multi-stage circulation mechanism includes multiple placement plates, with the farthest side of each placement plate fixedly connected to the inner wall of the operating frame. A limiting block is fixedly connected to the inner top of each placement plate. A sleeve is fixedly connected to the inside of each placement plate, and a buffer spring is fitted inside the sleeve. A support column is slidably connected to the inner top of the sleeve. A limiting plate is fixedly connected to the top of the support column. Multiple lower leakage holes are opened inside the limiting plate. A distribution component and a vibration component are fixedly connected to the outside of the operating frame.

[0007] Through the above technical solution: the material enters from the placement port and falls onto the limiting plate. The limiting block restricts the movement range of the material. After the vibration component is activated, it drives the limiting plate to vibrate. The support column slides inside the sleeve, and together with the buffer spring, it plays a buffering and stabilizing role, so that the material falls evenly through the lower drain hole under the action of vibration, realizing multi-stage circulation. The equalization component further evenly disperses the material to ensure uniform material distribution. The heating mechanism heats the material in the operating frame. The gas circulation mechanism forms a gas circulation in the operating frame through the support frame, providing fluidizing gas for the material. Under the action of hot gas, the material is in a fluidized state, accelerating the heat and mass transfer process. The multi-stage circulation mechanism realizes multiple circulation processing of the material, increases the contact time and contact area between the material and the hot gas, thereby improving the efficiency and uniformity of material drying, reaction and other processing, and ensuring stable and reliable processing results.

[0008] Preferably, the heating mechanism includes a partition frame, the outside of which is fixedly connected to the inside of the operating frame, a microwave device is fixedly connected to the inside of the partition frame, a microwave main controller is fixedly connected to the bottom of the microwave device, a dispersion plate is fixedly connected to both sides of the outside of the microwave device, multiple transmission ports are opened on both sides of the outside of the partition frame, multiple through holes are opened inside the partition frame, multiple placement plates are fixedly connected to the outside of the partition frame, and the top of the microwave main controller is fixedly connected to the inside top side of the support frame.

[0009] By adopting the above technical solution, in this internally heated vibrating fluidized bed, when the heating mechanism is running, the microwave main controller controls the microwave device to generate microwaves. The microwaves diffuse outwards through the penetration holes inside the partition frame, and the dispersion plate further disperses the microwaves evenly, ensuring that the microwaves can cover the materials in the operating frame. The transmission ports on both sides of the partition frame directly heat the inside of the materials with microwaves. The partition frame divides the internal space of the operating frame. Combined with the support structure of the placement plate, the materials pass through the microwave heating area in an orderly manner during the circulation process, increasing the microwave action time, improving heating efficiency, reducing energy loss, and ensuring that the materials are more evenly distributed during the heating process, thereby improving the overall processing effect.

[0010] Preferably, the gas circulation mechanism includes a hot circulation pump, the bottom of which is threadedly connected to the inner bottom side of the support frame. The output end of the hot circulation pump is fixedly connected to a delivery pipe, the outside of which is fixedly connected to a fixing buckle. Multiple dispersion pipes are fixedly connected to the outside of the delivery pipe. The receiving end of the hot circulation pump is fixedly connected to a return pipe, the outside of which is fixedly connected to a filter detector, and the outside of which is fixedly connected to a support buckle.

[0011] By adopting the above technical solution, after the hot circulating gas pump starts, it draws in hot gas that has been purified and detected by a filter detector through the return pipe. The filter detector can effectively remove impurities in the gas, ensuring gas cleanliness, and at the same time monitor the gas status to ensure stable circulating gas quality. The drawn-in hot gas is pressurized by the hot circulating gas pump and then transported through the delivery pipe. The fixing buckle ensures the stability of the delivery pipe and prevents shaking during the transportation process. The hot gas is evenly dispersed into the operating frame through the dispersion pipe, making full contact with the material, so that the material is fluidized under the action of the gas, realizing efficient heat and mass transfer. After completing the heating and fluidization of the material, the gas carrying the heat of the material and a small amount of particles returns to the hot circulating gas pump through the return pipe. The support buckle ensures the stability of the return pipe. In this cycle, the gas circulation mechanism not only provides fluidization power for the material by continuously circulating hot gas, but also recovers and utilizes the heat of the gas, reduces energy consumption, improves energy utilization, and ensures a stable gas environment in the operating frame, providing a guarantee for the stable processing of materials.

[0012] Preferably, the support buckle is externally fixedly connected to the outside of the operating frame, the fixing buckle is externally fixedly connected to the outside of the operating frame, and the other end of the dispersing tube is fixedly connected to the outside of the operating frame.

[0013] By adopting the above technical solution, the fixing buckle is fixed to the outside of the operating frame to ensure the stability of the conveying pipe and prevent shaking from affecting the gas conveying. Hot gas is introduced into the inside from the outside of the operating frame through the dispersion pipe, and the dispersion pipe evenly disperses the gas. The support buckle is fixed to the outside of the operating frame to ensure the stability of the return pipe.

[0014] Preferably, the equal distribution component includes a controller, which is externally fixedly connected to the outside of the operation frame. The output end of the controller is fixedly connected to a plurality of moving rods, and the other end of each moving rod is fixedly connected to a brush scraper. The bottom of the brush scraper is slidably connected to the top inner side of the limiting plate.

[0015] By adopting the above technical solution, the controller drives multiple moving rods to reciprocate, causing the brush scraper to slide on the inner side of the top of the limiting plate. When the material falls from the placement port onto the limiting plate, the brush scraper spreads the material evenly through mechanical movement to prevent material accumulation. This even distribution makes the material more orderly when passing through the lower discharge hole under vibration, avoiding problems such as local blockage or uneven feeding.

[0016] Preferably, the vibration assembly includes a mounting frame, the external thread of which is connected to the outside of the operating frame, a drive motor is fixedly connected to the other side of the mounting frame, and an eccentric wheel is fixedly connected to the output end of the drive motor.

[0017] By adopting the above technical solution, when the vibration component is working, the drive motor is powered on and runs, which drives the eccentric wheel to rotate at high speed. Since the center of gravity of the eccentric wheel is off from the center of rotation, a periodic centrifugal force is generated during the rotation. This centrifugal force is transmitted to the operating frame through the mounting frame, which in turn drives the limiting plate and other components in the operating frame to generate high-frequency vibration.

[0018] Preferably, the vibration is generated by the vibration component and transmitted to the placement plate through the operation frame, so that the limiting plate follows the vibration. When the limiting plate slides inside the sleeve through the support column, the buffer spring is squeezed and compressed by the support column inside the sleeve.

[0019] By adopting the above technical solution, in the vibration assembly, the drive motor drives the eccentric wheel to rotate at high speed. The resulting vibration is transmitted through the mounting frame to the operating frame, and then to the placement plate, causing the limiting plate to vibrate accordingly. During the vibration process, the limiting plate drives the support column to slide up and down inside the sleeve. When the support column moves downward, it will squeeze the buffer spring inside the sleeve, causing it to compress. The compression and rebound of the buffer spring plays a buffering and shock absorption role, reducing the impact of vibration on the overall structure of the equipment, protecting the operating frame and other components, and extending the service life of the equipment. On the other hand, the elastic force of the spring assists the limiting plate to reset, making the vibration of the limiting plate more stable, ensuring that the material vibrates evenly on the limiting plate and passes smoothly through the lower drain hole, thereby improving the processing effect and efficiency of the material in the multi-stage circulation process.

[0020] Preferably, the airflow output by the thermal circulation air pump is delivered to the dispersion tube through the delivery pipe. The dispersion tube delivers the airflow to the inside of the operating frame. Then, the airflow is led to the inside of the operating frame on the other side of the partition frame through the penetration hole. Then, the airflow is moved away from the inside of the operating frame through the return pipe and enters the filter detector for gas filtration and temperature detection before returning to the thermal circulation air pump for the next cycle.

[0021] By adopting the above technical solution, after the hot air circulation pump starts, the airflow is delivered to the dispersion pipe through the conveying pipe. The dispersion pipe evenly disperses the airflow into the inside of the operating frame, so that the material is fluidized under the action of the hot airflow, accelerating heat and mass transfer. The airflow passes through the penetration hole on the partition frame and reaches the operating frame on the other side of the partition frame. After fully contacting the material, it leaves the operating frame through the return pipe and enters the filter detector. Impurities in the airflow are filtered out, and its temperature and other parameters are detected to ensure that the gas is clean and meets the circulation requirements. The treated airflow returns to the hot air circulation pump to start the next cycle.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the drive motor in the vibration assembly drives the eccentric wheel to rotate, generating centrifugal force to drive the operating frame to vibrate, which is then transmitted to the placement plate, causing the limiting plate to follow the vibration. The support column slides and squeezes or releases the buffer spring in the sleeve, while the limiting block restricts its range of motion. Through the lower drain hole opened on the limiting plate, the material is driven to flow to the next level in an orderly manner during the vibration process, thereby realizing the multi-stage circulation processing of the material. Moreover, the material fully rolls and jumps on the limiting plate, enhancing the mixing effect of the material and improving the drying uniformity.

[0024] 2. In this utility model, with the cooperation of the microwave main controller and the dispersion plate, the microwaves generated by the microwave device can be evenly dispersed. With the cooperation of the partition frame and the dispersion plate, the microwave heating area remains stable. The operation frame is divided into different areas to solve the problem of uneven heating of materials, realize efficient non-contact heating of materials, and the heating process and results are divided into two parts to form a comparison effect, which is convenient for providing data and actual use effects for the research and development of fluidized beds.

[0025] 3. In this utility model, the cooperation between the delivery pipe and the dispersion pipe at the output end of the hot circulating gas pump and the return pipe enables the gas to circulate stably inside the equipment, thereby solving the problems of insufficient material fluidization and ineffective heat transfer. This drives the material to form a fluidized state and removes moisture and heat. With the cooperation of the filter detector and the hot circulating gas pump, the return gas can be effectively filtered and its parameters detected, thereby solving the problem of impurities in the circulating gas affecting equipment operation and the inability to accurately control the gas state. This provides data on the generated return gas for the development of fluidized beds. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0033] Example: An internally heated vibrating fluidized bed, referring to... Figures 1 to 3 The equipment includes an operating frame 1, which serves as the main frame of the equipment, providing installation space and support. The top two sides of the operating frame 1 are fixedly connected to placement openings 3, which are used for loading materials and serve as channels for materials to enter and exit the equipment, making it convenient for operators to put the materials to be processed into the equipment. The bottom of the operating frame 1 is fixedly connected to a support frame 2, which bears the overall weight of the equipment, ensuring that the equipment remains stable during operation and preventing shaking or tilting. The operating frame 1 is equipped with a multi-stage circulation mechanism 4 and a heating mechanism 5. The support frame 2 is equipped with a gas circulation mechanism 6.

[0034] The multi-stage circulation mechanism 4 includes multiple placement plates 41, which support the limiting plate 46 to form a material handling platform. The far side of the multiple placement plates 41 is fixedly connected to the inner wall of the operating frame 1. A limiting block 42 is fixedly connected to the top inner side of the placement plate 41. The limiting block 42 restricts the movement range of the limiting plate 46 to prevent it from shifting or detaching from the placement plate 41 during vibration. A sleeve 43 is fixedly connected inside the placement plate 41. The sleeve 43 provides sliding guidance for the support column 45 and accommodates the buffer spring 44. The buffer spring 44 is sleeved inside the sleeve 43 and plays a buffering role.

[0035] A support column 45 is slidably connected to the inner top of the sleeve 43. During vibration, the support column 45 slides inside the sleeve 43, causing the limiting plate 46 to vibrate and compressing or releasing the buffer spring 44. The limiting plate 46 is fixedly connected to the top of the support column 45. The limiting plate 46 is used to carry the material and causes the material to roll and jump under the action of vibration, so as to achieve mixing and uniform drying of the material. Multiple lower drain holes 47 are opened inside the limiting plate 46. The lower drain holes 47 are used to control the flow of the material so that the processed material can flow smoothly to the next level to achieve multi-level circulation processing. A distribution component 48 is fixedly connected to the outside of the operation frame 1. A vibration component 49 is fixedly connected to the outside of the operation frame 1.

[0036] Vibration is generated by the vibration component 49 and transmitted to the placement plate 41 through the operation frame 1, causing the limiting plate 46 to follow the vibration. When the limiting plate 46 slides inside the sleeve 43 through the support column 45, the buffer spring 44 is squeezed and compressed by the support column 45 inside the sleeve 43.

[0037] Specifically, the vibration component 49 outside the operating frame 1 generates vibration, which is transmitted through the operating frame 1 to the placement plate 41 fixed to its inner wall. The limiting block 42 on the inner side of the top of the placement plate 41 restricts the range of motion of the limiting plate 46, ensuring its stability during vibration. The sleeve 43 inside the placement plate 41 provides a sliding track for the support column 45. The buffer spring 44 inside the sleeve 43 plays a buffering and shock-absorbing role when the support column 45 slides up and down with the vibration of the limiting plate 46. Under the action of vibration, the limiting plate 46 carrying the material causes the material to roll and jump, achieving mixing and drying. The lower drain hole 47 inside controls the material flow, allowing the processed material to flow smoothly to the next stage. In addition, the equalization component 48 outside the operating frame 1 assists in the uniform distribution of the material, ensuring the efficient operation of multi-stage cyclic processing.

[0038] The equal distribution component 48 includes a controller 481, which receives equipment operating parameter signals to generate power. The controller 481 is externally fixedly connected to the outside of the operating frame 1. Multiple moving rods 483 are fixedly connected to the output end of the controller 481. The moving rods 483 drive the brush scraper 482 to move. The other end of each moving rod 483 is fixedly connected to the brush scraper 482. The brush scraper 482 pushes the accumulated material away and distributes it evenly on the limiting plate 46. The bottom of the brush scraper 482 is slidably connected to the top inner side of the limiting plate 46.

[0039] The vibration assembly 49 includes a mounting frame 491, which is used to mount the drive motor 492 outside the operating frame 1. The external thread of the mounting frame 491 is connected to the outside of the operating frame 1. The drive motor 492 is fixedly connected to the other side of the mounting frame 491. The drive motor 492 is used to generate power to drive the eccentric wheel 493 to rotate. The output end of the drive motor 492 is fixedly connected to the eccentric wheel 493. The eccentric structure of the eccentric wheel 493 generates centrifugal force, causing the equipment to vibrate.

[0040] Specifically, during operation, the controller 481 installed outside the operating frame 1 receives equipment operating parameter signals and drives multiple moving rods 483 connected to it to slide the brush scraper 482 on the inner side of the top of the limiting plate 46, pushing away the accumulated material and ensuring that the material is evenly spread on the limiting plate 46. At the same time, the mounting frame 491 threaded to the outside of the operating frame 1 fixes the drive motor 492. The eccentric wheel 493 at its output end rotates under the drive of the motor. The centrifugal force generated by the eccentric structure causes the operating frame 1 and its internal structure to vibrate. The vibration is transmitted through the placement plate 41, and the support column 45 slides in the sleeve 43 to compress the buffer spring 44. The limiting plate 46 vibrates accordingly, allowing the evenly distributed material to roll and jump on the plate, achieving mixing and drying. The lower drain hole 47 ensures that the processed material flows to the next level in an orderly manner, completing multi-stage cyclic processing.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The heating mechanism 5 includes a partition frame 51, which divides the interior of the operating frame 1 into different working areas, providing installation space for components such as the microwave device 53, and also serving as an isolation and protection mechanism to prevent microwave leakage and heat loss. The partition frame 51 is fixedly connected to the interior of the operating frame 1. The microwave device 53 is fixedly connected inside the partition frame 51. The microwave device 53 generates microwaves and heats the material through a non-contact heating method, achieving rapid and uniform heat transfer. The bottom of the microwave device 53 is fixedly connected to a microwave main controller 52, which is used to control the operation of the microwave device 53 and adjust parameters such as microwave power and frequency to ensure the effectiveness and safety of microwave heating.

[0042] Dispersion plates 54 are fixedly connected to both sides of the microwave device 53. The dispersion plates 54 are used to disperse microwaves so that microwaves can act on materials more evenly. Multiple transmission ports 55 are opened on both sides of the partition frame 51. The transmission ports 55 are used to disperse microwaves in different working areas. Multiple penetration holes 56 are opened inside the partition frame 51. The penetration holes 56 provide channels for gas circulation. Multiple placement plates 41 are fixedly connected to the outside of the partition frame 51. The top of the microwave main controller 52 is fixedly connected to the top inside the support frame 2.

[0043] Specifically, during equipment operation, the partition frame 51, fixed in the middle of the operating frame 1, divides the operating space into independent areas. The microwave device 53 installed inside generates microwave energy under the control of the microwave main controller 52. The microwave main controller 52 ensures the safety and uniformity of the heating process by adjusting the power and frequency parameters. The dispersion plates 54 on both sides of the microwave device 53 evenly diffuse the microwaves, which are then guided through the transmission ports 55 on both sides of the partition frame 51 to the limiting plate 46 area of ​​the multi-stage circulation mechanism 4, achieving non-contact heating of the material. The penetration hole 56 provides an airflow channel for the gas circulation mechanism 6, enabling efficient heat transfer between different working areas. The multi-stage circulation mechanism 4 connected to the outside of the partition frame 51 works in conjunction with the microwave main controller 52 supported on the top to ensure that the material continuously receives uniform microwave radiation during the vibration and tumbling process, achieving rapid drying and processing.

[0044] Reference Figure 1 , Figure 4 and Figure 5 The gas circulation mechanism 6 includes a hot air circulation pump 61, which drives the gas to circulate inside the equipment, providing the airflow required for fluidization of the material, and realizing the recycling of hot air to improve energy efficiency. The bottom of the hot air circulation pump 61 is threaded to the inner bottom side of the support frame 2. The output end of the hot air circulation pump 61 is fixedly connected to a conveying pipe 62, which is used to connect the hot air circulation pump 61 and the dispersion pipe 64, and deliver the gas output by the hot air circulation pump 61 to the dispersion pipe 64. The outside of the conveying pipe 62 is fixedly connected to a fixing buckle 63, which is used to fix the conveying pipe 62 and ensure that the conveying pipe 62 remains stable during the operation of the equipment. Multiple dispersion pipes 64 are fixedly connected to the outside of the conveying pipe 62, and the dispersion pipes 64 evenly disperse the gas delivered by the conveying pipe 62 into the inside of the operating frame 1.

[0045] The receiving end of the hot circulating air pump 61 is fixedly connected to a return pipe 65. The return pipe 65 is used to return the gas inside the operating frame 1 to the hot circulating air pump 61 to realize gas circulation. The outside of the return pipe 65 is fixedly connected to a filter detector 66. The filter detector 66 is used to filter dust and impurities in the gas and detect parameters such as temperature and humidity of the gas to ensure the quality and safety of the returned gas. The outside of the return pipe 65 is fixedly connected to a support buckle 67. The support buckle 67 is used to fix the return pipe 65 and ensure the stability of the return pipe 65 during equipment operation. The support buckle 67 is fixedly connected to the outside of the operating frame 1. The fixing buckle 63 is fixedly connected to the outside of the operating frame 1. The other end of the dispersion pipe 64 is fixedly connected to the outside of the operating frame 1.

[0046] The airflow output by the hot circulating air pump 61 is delivered to the dispersing pipe 64 through the delivery pipe 62. The dispersing pipe 64 delivers the airflow to the inside of the operating frame 1. Then, through the penetrating hole 56, the airflow is led to the inside of the operating frame 1 on the other side of the partition frame 51. Then, through the return pipe 65, it moves away from the inside of the operating frame 1 and enters the filter detector 66 to filter the gas and detect the temperature before returning to the hot circulating air pump 61 for the next cycle.

[0047] Specifically, during equipment operation, the hot air circulation pump 61 installed on the bottom side inside the support frame 2 starts, driving the gas to circulate within the equipment. The output end delivery pipe 62 delivers the airflow to the dispersion pipe 64. The fixing buckle 63 ensures the stability of the delivery pipe 62. After the dispersion pipe 64 evenly disperses the airflow, the gas enters the operating frame 1. The airflow flows through the penetration hole 56 of the partition frame 51 to the other side of the operating frame 1, realizing the fluidization and heating of the material. Subsequently, the gas leaves the operating frame 1 through the return pipe 65. Along the way, the filter detector 66 removes dust from the gas and detects temperature and humidity parameters to ensure gas quality. The support buckle 67 fixes the return pipe 65, allowing the gas to flow back stably to the hot air circulation pump 61. This cycle continues, and the hot air circulation pump 61 realizes the recycling of hot air, improving energy efficiency, while providing the airflow required for fluidization of the material, thus aiding in the drying process.

[0048] The implementation principle of this application embodiment is as follows: When the equipment is running, the material to be processed is put into the equipment through the placement ports 3 on both sides of the top of the operation frame 1. The material falls on the limiting plate 46. At this time, the vibration component 49 installed outside the operation frame 1 starts to work. The drive motor 492 drives the eccentric wheel 493 to rotate. The centrifugal force generated causes the equipment to vibrate. The vibration is transmitted to the placement plate 41 through the operation frame 1, which in turn causes the limiting plate 46 to vibrate. The support column 45 slides in the sleeve 43, squeezing or releasing the buffer spring 44. The limiting block 42 restricts the range of motion of the limiting plate 46. At the same time, the controller 481 of the equalizing component 48 receives the equipment operating parameter signal and controls the moving rod 483 to drive the brush scraper 482 to move, so that the accumulated material is evenly distributed on the limiting plate 46. The material rolls and jumps on the vibrating limiting plate 46 and achieves multi-stage circulation flow through the lower drain hole 47.

[0049] While the material is being processed, the heating mechanism 5 and the gas circulation mechanism 6 work together. The microwave main controller 52 controls the microwave device 53 to generate microwaves. After the microwaves are dispersed by the dispersion plate 54, non-contact heating is achieved. The hot circulation air pump 61, as the core of the gas circulation mechanism 6, draws gas from the return pipe 65 and delivers it to the inside of the operating frame 1 through the conveying pipe 62 and the dispersion pipe 64. The gas passes through the penetration hole 56, causing the material to form a fluidized state and carrying away moisture and heat. Then, it enters the filter detector 66 through the return pipe 65 to filter impurities and detect parameters, and then returns to the hot circulation air pump 61 to complete the circulation. The fixing buckle 63 and the support buckle 67 respectively ensure the stability of the conveying pipe 62 and the return pipe 65. The partition frame 51 ensures the stability of the microwave heating area and prevents microwave leakage and heat loss.
