Anti-agglomeration device using ultrasonic waves for a nanofluid

An anti-agglomeration device for a nanofluid, comprising:

• a support module;
• a motion module;
• a photoacoustic conversion module;
• and
• a control module;
• wherein the support module comprises a frame and screws;
• the frame is configured to support the photoacoustic conversion module and the motion module;
• the motion module comprises a servo motor, a dovetailed rail, a guide screw, a fixed plate, a slider and a deep groove ball bearing;
• the dovetailed rail is arranged on the frame via bolts;
• the guide screw is connected to the slider, and connected to the servo motor through the deep groove ball bearing;
• and the motion module consists of three groups of motion modules;
• the photoacoustic conversion module comprises a nanosecond laser, a first clamp, a lens, a silica optical fiber, a second clamp, gold nanoparticles and a container;
• the nanosecond laser is fixed on the fixed plate;
• the first clamp is configured to hold the lens;
• the second clamp is configured to fix the silica optical fiber;
• the container is configured to store a nanogold solution formed from the gold nanoparticles;
• the container is fixed on a bottom of the silica optical fiber via bolts, and a fiber core of the silica optical fiber at its end is inserted into the nanogold solution;
• laser pulses generated by the nanosecond laser interacts with the gold nanoparticles in the container, and the gold nanoparticles periodically expand and shrink in volume under pulsed laser irradiation to generate ultrasonic waves;
• and
• the control module comprises a support plate, a charge-coupled device (CCD) camera and the nanofluid;
• the CCD camera is configured to monitor a suspension state of nanoparticles in the nanofluid;
• when agglomeration of the nanoparticles weakens a light signal acquired by a photosensitive element of the CCD camera, an instruction is issued to a computer control system to activate the motion module, so that the photoacoustic conversion module moves to an area where the agglomeration occurs and sends the ultrasonic waves to disperse the agglomerated nanoparticles.
