[0019] Please refer to Figure 4 The outer part of the blowing pipe rack 13 is fixedly provided with a cleaning plate 23, one end of which is in contact with the inner wall of the drying tower 1. The main function of the cleaning plate 23 is to physically scrape the inner wall of the drying tower 1 to remove the material or stains adhered thereto. The cleaning plate 23 is usually fixedly connected with the blowing pipe rack 13 and moves along with the rotation of the rotating disc 12, thereby achieving uniform cleaning of the inner wall of the drying tower 1. When the air flow provided by the air blower 22 is sprayed to the inner wall of the drying tower 1 through the air pipe 15 and the nozzle 14, the scraping function of the cleaning plate 23 is combined with the air flow blowing, which can more effectively remove the adhered material. With the rotation of the rotating disc 12, the cleaning plate 23 can uniformly clean along the circumferential direction of the inner wall of the drying tower 1, ensuring that every corner can be thoroughly cleaned.
[0020] The working principle is that the drying tower 1 is the core of the drying process, and the drying tower 1 provides a closed environment for the atomization and hot air drying of the material. Inside the drying tower 1, a high-speed atomizer 10 is provided for atomizing the material in the material storage tank 5 into tiny droplets. The air blower 1 is responsible for sending external air into the system to provide a fresh air source for the heater 3. Through the operation of the air blower 1, the system can continuously obtain the required air volume to maintain the stable progress of the drying process. The heater 3 heats the air sent by the air blower 1 to meet the temperature conditions required for drying. The heated air is sent into the drying tower 1 through the pipe body 4 to provide the necessary heat energy for the drying of the material. The pipe body 4 serves as a bridge connecting the heater 3 and the drying tower 1, and is responsible for sending the heated air into the drying tower 1. The material storage tank 5 is used to store the material to be dried. The cyclone separator 6 uses the centrifugal force generated when the gas-solid mixture rotates at high speed to separate dust from the gas flow. The cyclone separator 6 serves as a primary dust removal device and can remove most of the dust particles generated during the drying process, reducing the burden on the subsequent bag dust collector 7. The bag dust collector 7 filters the dust-containing gas through the filter bag, trapping the dust particles on the surface of the filter bag. The bag dust collector 7 serves as a secondary dust removal device and can further remove fine dust particles in the gas flow, ensuring that the exhaust gas meets environmental protection requirements. The induced draft fan 8 draws exhaust gas from the system and sends it to the exhaust gas treatment tank 9 for further treatment. The exhaust gas treatment tank 9 further processes the exhaust gas sent by the induced draft fan 8, such as purification and deodorization. The exhaust gas treatment tank 9 is one of the key devices to ensure that the drying process meets environmental protection requirements and can significantly reduce the pollution of exhaust gas to the environment. Through the installation of the blowing pipe rack 13, the rotation of the blowing pipe rack 13 is achieved by the engagement of the driving gear 18 and the driven gear 16 driven by the motor 17. At the same time, the airflow provided by the air blower 2 is injected into the inner wall of the drying tower 1 through the air pipe 15 and the nozzle 14, thereby achieving effective removal of the adhered material. This avoids the problem of the material being burned or deteriorated due to long-term residence on the inner wall, thereby affecting the overall quality of the product. This not only improves the drying efficiency but also reduces energy consumption and maintenance costs. The shaft body 11 is rotatably arranged on the drying tower 1 and serves as a support and transmission component for the rotating disc 12 and the blowing pipe rack 13. The rotating disc 12 is fixedly installed at the top of the shaft body 11 and located inside the drying tower 1. The design of the rotating disc 12 allows the blowing pipe rack 13 to rotate with the shaft body 11, thereby achieving comprehensive blowing of the inner wall of the drying tower 1. The blowing pipe rack 13 is fixedly arranged on the rotating disc 12 and has multiple blowing structures that can cooperate with the inner wall of the drying tower 1. These blowing structures are radially distributed to ensure uniformity and comprehensiveness of blowing. The nozzle 14 is arranged on the blowing pipe rack 13 and is used to inject airflow into the inner wall of the drying tower 1. The number and layout of the nozzles 14 should be reasonably designed according to the size and shape of the drying tower 1 to achieve the best blowing effect.The driving gear 18 is fixedly arranged on the output end of the motor 17 and is engaged with the driven gear 16, when the motor 17 is started, the driving gear 18 drives the driven gear 16 and the shaft body 11 to rotate, and then drives the rotating disc 12 and the blowing pipe frame 13 to rotate and blow, the air pipe 15 is fixedly arranged in the shaft body 11, and is used for conveying the airflow provided by the air blower two 22 to the blowing pipe frame 13 and the nozzle 14, the air blower two 22 is fixedly arranged on the frame body 19, and the air outlet end of the air blower two 22 is connected with one end of the connecting pipe 20, the air blower two 22 is responsible for providing sufficient airflow pressure, so that the nozzle 14 can spray strong airflow to blow the inner wall of the drying tower 1, the connecting frame 21 is movably arranged at the bottom end of the air pipe 15, and is used for connecting the air pipe 15 and the connecting pipe 20, the connecting pipe 20 is fixedly arranged on the connecting frame 21 and is connected with the air outlet end of the air blower two 22, through the meshing transmission of the driving gear 18 and the driven gear 16 driven by the motor 17, the rotating disc 12 and the blowing pipe frame 13 are realized to rotate and blow, at the same time, the airflow provided by the air blower two 22 is sprayed to the inner wall of the drying tower 1 through the air pipe 15 and the nozzle 14, so that the adhered material is effectively removed, the material is prevented from being scorched or deteriorated due to long-time stay on the inner wall, and the problem that the overall quality of the product is affected is avoided, so that the drying efficiency is improved, and the energy consumption and the maintenance cost are reduced, the main function of the cleaning plate 23 is to physically scrape the inner wall of the drying tower 1 to remove the material or stain adhered on the inner wall, the cleaning plate 23 is usually fixedly connected with the blowing pipe frame 13 and moves along with the rotation of the rotating disc 12, so that the inner wall of the drying tower 1 is uniformly cleaned, when the airflow provided by the air blower two 22 is sprayed to the inner wall of the drying tower 1 through the air pipe 15 and the nozzle 14, the scraping function of the cleaning plate 23 is combined with the airflow blowing, and the adhered material can be more effectively removed, along with the rotation of the rotating disc 12, the cleaning plate 23 can uniformly clean along the circumferential direction of the inner wall of the drying tower 1, and it is ensured that every corner can be thoroughly cleaned.
