Abstract:
Objective To design a centrifugal agtomization principle-based disinfection and disinsection device for plateau areas.Methods A disinfection and disinsection device was developed based on centrifugal atomization principle,which was composed of a spraying body,lifting and rotating mechanisms,an electrical control system,a spray tank and a sprayer carriage.The spraying body consisted of spraying components,a motor,an air blower,a fan and etc,and the spraying components adopted the structural form of multi-layer disc stacking to realize the atomization of liquid medicine;the lifting mechanism implemented up-and-down adjustment of the air blower through an electric actuartor,and the rotating mechanism executed left-and-right adjustment of the air blower thrgouth the worm gear motor and limit switch;the electrical control system was made up of a power source,electrical devices,a distribution system and a control system,in which a lead-acid battery pack was used for power supply and a DGUS touch screen and a DCS001 controller were involved in the control system;the spray tank was formed of a tank body,a needle valve,a water pump,float switch,etc;the sprayer carriage comprised a frame,a pusher,two sealing plates and four wheels.Some disc samples with different diameters were trial produced,and comparison experiments were carried out to investigate the relationship between disc diameter,motor speed,spray flow rate and atomization effect;a prototype was manufactured for performance testing of the device.Results The disc diameter and motor speed were inversely proportional to the droplet size;the spray flow rate was directly proportional to the droplet size,when the spray flow rate increased by 60%,the increment of the droplet size was restrained within 2%to 11%.The prototype test results indicated that the device could be used for ultra-low-volume disinfection and insecticide in plateau areas,with the D50 and D90 of the droplet size being 31 and 48 μm,respectively.Conclusion The device developed gains advantages in atomiztion,and meets the requirements for epidemic prevention,disinfection and disinsection in plateau areas.[Chinese Medical Equipment Journal,2025,46(4):35-39]
