The invention discloses a
test tube cleaning device. The
test tube cleaning device comprises an air supply device, an air passing
pipe, a water passing
pipe, a
water supply device, a water knockout drum, a stable frame, a washing tank, a stepping motor I, a bearing base, a fixing piece, a polished rod, lead screws, sliding blocks,
test tube clamping sleeves, a platform, small gears I, a big gear I, a stepping motor II, a supporting frame, a water dividing hose, cleaning columns, a big gear II and small gears II. The communicator principle is adopted in the test
tube cleaning device, sufficientcontact between water and test tubes can be guaranteed,
dirt on the surfaces of the test tubes falls off through high-frequency vibration signals sent by ultrasonic
waves, then, the inner walls of the test tubes are cleaned through mechanical rotation of the cleaning columns, and meanwhile water is sprayed for secondary cleaning. When cleanliness meets the requirement, hot air and an
air heater are adopted for
drying the test tube walls. According to the device, the cleaning time is adjustable, the rotation speed is adjustable, the test
tube cleaning device is applicable to the test tubes different in specification, and operation is simple, fast and practical; and good market competiveness is achieved, and the test
tube cleaning device can be applied to colleges, hospitals, enterprises and the like.
