Test tube cleaning device

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of chemical experiments, in particular to a test tube cleaning device. Background technique [0002] At present, the cleaning devices for test tubes are mainly divided into two categories. One is manual test tube brushes. This method is simple and convenient, but the cleanliness is not high, and it will consume time and labor. High strength; test tube is a common chemical vessel, mainly divided into ordinary test tubes, test tubes with supports, centrifuge test tubes, etc. Ordinary test tubes can be used to heat solids or reagents, and are places where reactions of acidic, alkaline, and toxic substances occur. If it is directly cleaned manually, it may cause harm to people. Even with protective gloves, accidents will inevitably occur. Therefore, there are above various defects in this artificial test tube brush. The other type is the instrument cleaned by ultrasonic waves, which is expensive at first, requ...

Problems solved by technology

One of the test tube cleaning devices for chemical tests uses a combination of ultrasonic cleaning and spray cleaning to achieve fixed cleaning of test tubes of different lengths, but lacks a mechanical friction cleaning process, which cannot guarantee the cleaning quality. Drying is integrated; a test tube cleaning device has a simple structure, but it may cause liquid splashing when pouring residual liquid, and the safety factor is low; a test tube cleaner adopts graded cleaning, but the spray cleaning effect is poor

[0004] At present, most of these two test tube cleaning devices are researchers in hospitals, enterprises, universities and scientific research institutes. The time of these people is relatively precious, but both methods have certain defects. Generally speaking, intelligent The market prospect of the test tube cleaning machine is very good. Relevant universities, hospitals, enterprises and scientific research institutes urgently need a test tube automatic cleaning device with high reliability, high degree of automation and strong operability.
