[0005] To achieve the above-mentioned purpose, the present invention provides a boiling drying system, including a boiling drying system body, the boiling drying system including a drying body, an operating platform is provided on one side of the drying body, a boiling bed assembly is provided inside the drying body, a feeding assembly is provided outside the boiling bed assembly, a discharge hopper is provided on the other side of the drying body, the discharge hopper is provided with a related fan, the drying body is also provided with an induced draft assembly, the drying body is provided with a trough mixer, the boiling bed assembly is provided with a heating device, the boiling bed assembly is provided with a boiling bed body, and a ventilation duct is provided inside the boiling bed body.

[0006] As a further improvement of the present invention, in order to effectively filter the air entering the system and remove impurities and dust, the fluidized bed assembly is provided in conjunction with a body frame, an air filter is provided above the body frame, multiple groups of the air filters are provided, and adjacent air filters are provided at a certain distance. The air filter is provided in conjunction with a radiator, multiple groups of the radiator are provided, and the radiator is provided at the connection between the air filter and the body frame.

[0007] As a further improvement of the present invention, in order to make air filtration more efficient and facilitate maintenance and replacement of air filters, thereby improving the overall ventilation efficiency of the system, each group of air filters is provided with an air inlet diameter circle, the air inlet diameter circle is provided with an air inlet main pipe, and the air filters are connected to the air inlet main pipe via the air inlet diameter circle.

[0008] As a further improvement of the present invention, in order to more effectively remove moisture and other waste gases and realize reasonable distribution and regulation of wind force, the induced draft component includes an induced draft main duct, the induced draft main duct is cooperated with induced draft straight ducts and air regulating straight ducts, the induced draft main duct receives wind force from multiple induced draft straight ducts, the induced draft straight ducts and air regulating straight ducts are cooperated with several groups of bent pipes, a high-pressure induced draft fan is arranged on one side of the bent pipe, and a conical pipe is arranged between the high-pressure induced draft fan and the bent pipe.

[0009] As a further improvement of the present invention, in order to allow the material to be evenly heated and stirred by air flow and improve the drying effect, the fluidized bed assembly includes a box body, which is made of stainless steel corrosion-resistant material. A heating device and a ventilation duct are arranged inside the box body for heating and stirring the material by air flow. A flower plate is arranged above the box body, and a plurality of small holes or channels are usually arranged on the surface of the flower plate. An enlarged body is arranged in the middle of the box body, and an air distribution square circle is arranged below the box body.

[0010] As a further improvement of the present invention, in order to enable the material to enter the drying system continuously and stably, the feeding assembly includes a swing granulator, the swing granulator is arranged on one side of the drying body, the swing granulator is connected to a feed hopper via a pipeline, and the feed hopper is connected to the fluidized bed assembly.

[0011] One beneficial effect of the present invention is that the present invention provides a boiling drying system, and the beneficial effects of the boiling drying system are specifically embodied in the following aspects: Efficient drying: Through the setting of the fluidized bed assembly and the heating device, the system can achieve fast and efficient drying of the material. The ventilation ducts in the fluidized bed ensure the uniform distribution of the airflow, so that the material is dried in a boiling state, which improves the drying efficiency.

[0012] Air purification and heat dissipation: The multiple groups of air filters above the machine frame can effectively filter the air entering the system, remove impurities and dust, and ensure the cleanliness of the drying process. At the same time, the radiator is set at the connection between the air filter and the machine frame, which helps to dissipate heat in time, keep the temperature inside the system stable, and prevent overheating from causing damage to the system.

[0013] Optimized air intake design: Each set of air filters is connected to the main air intake pipe through an air intake square. This design not only facilitates the maintenance and replacement of the air filters, but also improves the air intake efficiency and ensures sufficient and stable airflow inside the system.

[0014] Efficient induced draft and dehumidification: The design of the induced draft components enables the system to remove moisture and other waste gases more effectively. The coordination of the induced draft main pipe, induced draft straight pipe, air adjustment straight pipe and elbow pipe realizes the reasonable distribution and regulation of wind force. The setting of high-pressure induced draft fan and conical pipe further improves the induced draft efficiency, ensuring the stable operation of the system and the timely discharge of moisture.

[0015] Corrosion resistance and durability: The box of the fluidized bed assembly is made of stainless steel corrosion-resistant material, which has good corrosion resistance and durability, can adapt to the drying needs of various materials, and extend the service life of the system.

[0016] Continuous production and feeding: The feeding assembly includes a swing granulator and a feeding hopper. This design allows the material to enter the drying system continuously and stably, improving production efficiency and continuity. The swing granulator also helps with the initial handling and granulation of the material, providing better conditions for the subsequent drying process.

[0017] The present invention also provides a process method of a fluidized bed drying system, the process method comprising the following steps: Step 1: Before starting the system, the system must be fully inspected. Confirm whether all components are intact, whether the connections are tight, whether the power supply, water supply and compressed air supply are normal, and thoroughly clean the system to ensure that there is no residue in the system, especially the fluidized bed components and induced draft components, to avoid contamination of the materials; Step 2: Start the heating device to preheat the fluidized bed so that the bed temperature reaches the set drying temperature; at the same time, turn on the induced air component and adjust the induced air volume to prepare for the subsequent drying process; Step 3: According to the properties and drying requirements of the materials, the materials are fed into the swing granulator and necessary pretreatment is performed on the materials, such as crushing, screening, mixing, etc., to ensure that the materials meet the feeding requirements of the system; Step 4: Detect the moisture content and particle size of the pretreated material in order to more accurately control the drying process; Step 5: Feed the material evenly into the fluidized bed assembly through the feed hopper. After the material enters the fluidized bed assembly, it is fully in contact with the hot air, and the moisture on the surface of the material is quickly evaporated. At the same time, the air flow stirs the material to roll in a boiling state, further accelerating the drying speed. In this process, the temperature and flow of the hot air need to be kept stable; Step 6: During the drying process, it is necessary to pay close attention to the degree of dryness and moisture content of the material. This can be done by observing the color and shape of the material and using equipment such as a moisture detector for real-time monitoring. According to the monitoring results, the process parameters such as hot air temperature, flow rate, and induced air volume can be adjusted in a timely manner to ensure the stability and consistency of the drying effect; Step 7: When the material reaches the drying requirement, close the feed assembly and stop adding material into the fluidized bed. At the same time, continue to keep the hot air supply and induced draft assembly running to fully dry the remaining material in the fluidized bed. Step 8: When the material in the fluidized bed is completely dry, open the discharge hopper and the fan to discharge the dried material out of the system; during the discharge process, keep the discharge hopper and the fan running smoothly to avoid material blockage or overflow; Step 9: Conduct quality inspection on the collected dry materials to ensure that they meet the quality standards; if necessary, further screening, packaging and other operations can be performed on the materials. After the materials are dried, turn off the system power, stop the hot air supply and the operation of the induced draft components, and at the same time, close the discharge hopper and turn off the fan and other components to ensure that the system is completely shut down.

[0018] Another beneficial effect of the present invention is that the present invention also provides a process method for a fluidized bed drying system, and the beneficial effects of the process method are embodied in the following aspects: Efficient drying: By preheating the fluidized bed and adjusting the hot air temperature, flow rate, induced air volume and other parameters, the material is fully in contact with the hot air in a boiling state, which greatly speeds up the drying speed and improves the drying efficiency.

[0019] Stable quality: During the drying process, we pay close attention to the dryness and moisture content of the material, and ensure the stability and consistency of the drying effect through real-time monitoring and adjustment of process parameters, thereby ensuring the stable quality of the dried material.

[0020] Avoid contamination: Before starting the system, the system is thoroughly inspected and cleaned, especially the fluidized bed components and induced draft components, to effectively avoid the problem of residues contaminating the material. At the same time, the material is also strictly controlled during the pretreatment and drying process, further ensuring the purity of the product.

[0021] Easy to operate: The process has clear steps, simple operation and easy to master. Through reasonable parameter setting and real-time monitoring, the operator can easily control the entire drying process, reducing the difficulty of operation and labor intensity.

[0022] When the present invention is working, first, a comprehensive inspection will be carried out before the system is started, including confirming the integrity and tightness of each component, as well as the normality of the supply of power, water and compressed air. The system will be thoroughly cleaned to ensure that there is no residue, especially the fluidized bed assembly and the induced draft assembly, so as to avoid contamination of the material.

[0023] Next, the heating device will be started to preheat the fluidized bed so that the bed temperature reaches the set drying temperature. At the same time, the induced air component will also be turned on and the induced air volume will be adjusted to prepare for the subsequent drying process.

[0024] In terms of material processing, according to the nature of the material and the drying requirements, the material will be sent to the swing granulator for necessary pretreatment, such as crushing, screening, mixing, etc., to ensure that the material meets the system's feed requirements. The pretreated material will be tested for moisture content and particle size in order to more accurately control the drying process.

[0025] Then, the material is evenly fed into the fluidized bed assembly through the feed hopper. In the fluidized bed assembly, the material is fully in contact with the hot air, and the moisture on the surface of the material is quickly evaporated. At the same time, the air flow stirs the material to roll in a boiling state, further accelerating the drying speed. In this process, the temperature and flow of the hot air need to be kept stable.

[0026] During the drying process, pay close attention to the degree of dryness and moisture content of the material. You can monitor in real time by observing the color and shape of the material and using equipment such as moisture detectors. According to the monitoring results, the system will adjust the process parameters such as hot air temperature, flow rate and induced air volume in time to ensure the stability and consistency of the drying effect.

[0027] When the material reaches the drying requirement, the system will close the feed component and stop adding material into the fluidized bed. At the same time, the hot air supply and induced draft components will continue to operate to fully dry the remaining material in the fluidized bed.

[0028] Finally, when the material in the fluidized bed is completely dry, the system will open the discharge hopper and the fan to discharge the dried material out of the system. During the discharge process, the system will keep the discharge hopper and the fan running smoothly to avoid material blockage or overflow. The collected dry material will be quality inspected to ensure that it meets the quality standards; if necessary, the material can be further screened, packaged, etc. After the material is dried, the system will turn off the power supply, stop the operation of the hot air supply and the induced draft components, and shut down the discharge hopper and the fan to ensure that the system is completely shut down.
