[0002] Electronic component ceramic powder is a ceramic raw material used to manufacture electronic components.

Common ceramic powders include alumina, zirconium oxide, etc. Through molding, sintering and other processes, it is made into ceramic substrates, capacitors, sensors and other electronic components, playing an important role in the electronics industry.

[0003] Traditional ceramic powder is dried and prepared through a spray drying process. When drying ceramic powder, the ceramic thin material is pressurized and atomized by a pressure pump mechanism and then sprayed into a drying chamber through a nozzle to contact with hot air for drying. At present, the high-temperature air used in the spray drying device in this process only plays an evaporation and drying role on the slurry, and is not effectively utilized in other aspects. This has caused energy waste to a certain extent. Moreover, part of the powder formed after drying is adhered to the inner wall of the drying device and the atomizing nozzle, which is inconvenient to clean, increasing the cleaning cost and affecting the service life of the drying device.

[0015] Technical effects and advantages of the present invention: The present invention utilizes a setting mode in which a lifting mechanism, a cleaning heat exchange mechanism, a pipeline opening and closing mechanism and a flushing mechanism are coordinated. The lifting mechanism can not only enable the cleaning heat exchange mechanism to clean the inner wall of the drying tank, but also can exchange the heat inside the drying tank through water flow and preheat the ceramic powder slurry inside the material barrel. At the same time, the opening and closing of different pipelines inside the pipeline opening and closing mechanism can be adjusted by the lifting and lowering of the lifting mechanism, so that the flushing mechanism can flush the atomizing nozzle when needed, thereby avoiding energy waste, saving cleaning costs, extending the service life of the drying device, and facilitating use. The present invention utilizes a scraper ring, a lifting rod, a heat exchange rod, a pipe connection assembly and a bottom cleaning assembly to cooperate with each other. The lifting mechanism can drive the scraper ring to move vertically on the inner wall of the drying tank. The bottom cleaning assembly can be used to clean the inner wall of the entire drying tank to prevent some ceramic powder from adhering to the inner wall during drying. At the same time, when the scraper ring is lifted and displaced, the heat inside the drying tank can be exchanged through the heat exchange rod, so that the water inside the first heat exchange chamber is heated, and the heated water can flow to the inside of the second heat exchange chamber inside the material barrel through the pump body, so that the original slurry inside the material barrel can be preheated, and the temperature of the drying tank gradually decreases from the top to the bottom. When preheating ceramic powders of different materials, the water temperature can be adjusted by adjusting the position of the scraper ring, so that the application range is wider, the waste heat in the spray drying process can be better recovered, and energy waste can be reduced. The present invention utilizes a configuration mode in which the first connecting pipe, the valve body, the second connecting pipe, the pump body, the third connecting pipe, the water inlet pipe, the valve stem and the pipeline opening and closing mechanism are matched with each other. The pump body can realize pumping hot water inside the scraper ring to the inside of the material barrel, and the lifting and lowering of the lifting mechanism can enable the opening and closing plate in the pipeline opening and closing mechanism to rotate the valve stem, so that the water inlet pipe is closed during heat exchange preheating, and can be opened when the flushing mechanism is needed for flushing, so that water flow is continuously provided to flush the atomizing nozzle, which is convenient for use. The present invention utilizes a setting mode in which a fixed rod, a slide plate, a sleeve, a compression spring and a nozzle assembly are matched. When the atomizing nozzle does not need to be flushed, the scraper ring is located inside the drying tank and is not pressed against the top of the inner wall. At this time, the rotating nozzle in the nozzle assembly will block the spray hole of the fixed nozzle under the elastic force of the compression spring, thereby preventing water leakage and preventing the spray hole from being blocked by ceramic powder. When the atomizing nozzle needs to be flushed, the scraper ring can be raised to the highest point by the lifting mechanism, thereby closing the air inlet hole. At the same time, the sleeve can be squeezed by the inner wall of the drying tank, so that the compression spring is in an extreme compression state. At this time, the gear ring can be driven to rotate by the rack, thereby causing the rotating nozzle to rotate. During the rotation, not only can the cleaning rod clean the powder inside the arc groove, but also the spray hole of the fixed nozzle can be exposed, so that water can be sprayed out to clean the atomizing nozzle.

At the same time, the sleeve 93 will be squeezed by the inner wall of the drying tank 2, so that the compression spring 94 is in an extreme compression state. At this time, the gear ring 954 can be driven to rotate by the rack 955, so that the rotating nozzle 952 rotates. During the rotation, not only can the cleaning rod 956 clean the powder inside the arc groove 958, but also the nozzle hole 957 of the fixed nozzle 951 can be exposed, so as to spray water to clean the atomizing nozzle 10.
