Description

Inverted test tube cleaning device

Technical Field

The utility model belongs to chemical container belt cleaning device relates to a test tube washing unit, especially an inversion formula test tube belt cleaning device.

Background

The test tube is a common reaction vessel and is widely applied to the research fields of chemical industry, pharmacy, biology and the like.

The test tube needs to be cleaned after being used, and a manual test tube brush is generally matched with pure water for cleaning in some laboratory tests or tests with low requirements on the purity of reagents. However, in some industrial-grade preparation processes or tests with high requirements for reagent purity, some test tube devices are required to be used for cleaning in order to reduce the labor intensity of workers and ensure the cleanliness of test tubes.

At present, the principle of the test tube cleaning equipment is relatively simple, an automatic water supplementing device is generally adopted to fill cleaning solution into a test tube, and meanwhile, a hairbrush capable of axially rotating is stretched into the test tube to clean, and various devices are different greatly. The most preferable one is an inverted structure, which has the advantage that the cleaning solution can flow out from the test tube opening under the action of its own weight after the cleaning solution washes the inner surface of the test tube.

However, the device with the above structure as the core has some disadvantages in the practical application process. Use patent number 2017207336968, the name is a quartz test tube cleaning device's technique for example, its device structure of using the principle design that the test tube was invertd includes accepting dish, stand, wash bowl, micro-water pump, CD-ROM drive motor etc. its principle lies in through the leading-in cleaning solution of micro-water pump to wash bowl, wash bowl outside suit test tube, CD-ROM drive motor installs and accepts dish side bottom drive wash bowl lower extreme rotation and realize cleanly. In practical use, the driving device, the transmission device, the cleaning solution storage device and the waste liquid guiding device are all arranged below the receiving tray, so that the device is complex in structure and large in size, and the problem of waste liquid guiding treatment needs to be solved in use. Although the receiving disc is adopted to guide the waste liquid, in the actual use process, particularly when some test tubes used for preparing reagents with higher purity requirements are cleaned, the water consumption is very large, so that the problem of splashing of the waste liquid is difficult to solve, the splashing waste liquid can seriously influence the use of the device, and particularly, the electric control structure which is very sensitive to water, namely the driving device and the transmission device, can cause direct damage to the device.

And the lower end surface of the rotating disc is integrally provided with an elastic sheet made of rubber materials, and the lower end surface of the elastic sheet is provided with the caulking groove.

And, the outside of each screw rod that is located the clamp plate top all is equipped with a stop nut.

And, every the water guide post outside all overlap and be equipped with a sleeve pipe, this suit outside is from top to bottom evenly the interval install a plurality of brushes.

The utility model has the advantages that:

the utility model discloses in, the setting of base, inside water pipe, water inlet and delivery port all is the same with current device principle, nevertheless moves gear motor and chain, devices such as gear through the clamp plate of suspension dress upward. When cleaning the use, the isolating device can be regarded as to test tube itself, realizes that the water is kept apart, and test tube open position is kept away from with the clamp plate, and water guide direction is opposite with the clamp plate position, consequently can not receive the influence of water completely, simple structure, and the technique is reasonable, not only can prolong the life of device, has also reduced the volume of device, has reduced the finished product of device.

The utility model adopts the structure that the elastic sheet is arranged at the bottom of the rotating disc, and the function of the elastic sheet is to ensure that the rotating disc can be tightly pressed and fixed with the outer surface of the test tube, so as to drive the test tube and the rotating disc to concentrically rotate at the same speed; in the use process, due to the dead weight of the pressure plate and the transmission device arranged in the pressure plate, the pressure plate and the outer end face of the bottom of the test tube are fixedly pressed and connected, and then the high position of the pressure plate in the vertical direction can be limited in the use process by matching with the limiting nut, so that the stability in the rotation process is ensured; the sleeve pipe is then used for installing the brush, and when treating that clear test tube size is different, the accessible is changed the sleeve pipe that is fit for the size and is cooperated, prevents that sleeve pipe external diameter undersize from causing circumference to rock at the rotatory in-process of test tube.
