Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic spraying equipment, specifically relating to an ultrasonic spraying equipment for high-temperature pyrolysis. Background Technology

[0002] Ultrasonic spraying equipment is a production device that uses ultrasound to atomize a solution for precision spraying. Its principle is to convert high-frequency electrical signals (typically 20kHz-3MHz) into mechanical vibrations through a piezoelectric transducer, and then transmit the vibration force to the nozzle, causing the sprayed liquid to form tiny atomized droplets that are evenly coated onto the surface of the substrate, creating a uniform coating. Ultrasonic spraying is widely used in new energy batteries, medical devices, aerospace technology, microelectronics, and other technical fields due to its advantages such as high coating uniformity, low material waste (less than 10%), high precision in coating thickness control, wide adaptability, and low maintenance costs.

[0003] Currently, there are many descriptions of the structure of ultrasonic spraying devices. For example, patent application number "201620259328.X" describes an ultrasonic ultrafine particle spraying device, including an ultrasonic generator, an ultrasonic transducer, and an ultrasonic nozzle. The ultrasonic transducer is mounted on a bracket with an opening at the bottom and a downward mounting protrusion, featuring easy disassembly and good atomization effect. Another example is patent application number "202221442246.0," which describes an ultrasonic precision spraying device suitable for internal wall spraying, including an ultrasonic nozzle assembly, a feeding system, a three-axis walking mechanism, an automatic loading and unloading mechanism, electrical control components, a touch screen, and a device frame, featuring a compact structure, high spraying efficiency, and a high degree of automation. However, existing ultrasonic spraying devices generally operate at room temperature or low temperature, and the maximum temperature of the supporting heating plate is below 200℃, making them unsuitable for products requiring high-temperature pyrolysis for spraying. Therefore, the structure of existing ultrasonic spraying equipment needs further improvement. Utility Model Content
