An automatic cleaning system for cuvette in laboratory processing

Abstract

The invention belongs to the cuvette cleaning device field and discloses an automatic cuvette cleaning system in laboratory treatment. The system comprises a working chamber and a cleaning chamber, asliding rail is connected between the working chamber and the cleaning chamber in a penetrating mode, a linear motor is arranged on the sliding rail, and a stepping motor is fixedly connected to the linear motor. The stepping motor is connected with a first connecting rod. A hollow box body is arranged at the other end of the first connecting rod. A second waste liquid tank, a third waste liquid tank and a fourth waste liquid tank are arranged in the cleaning chamber. A first liquid discharging pipe which is vertically arranged is arranged above the second waste liquid tank, a second liquid discharging pipe which is vertically arranged is arranged above the third waste liquid tank, and a third liquid discharging pipe which is vertically arranged is arranged above the fourth waste liquid tank. An exhaust fan with a downward air port is arranged on one side, away from the second liquid discharging pipe, of the third liquid discharging pipe, and an electric heating wire is arranged belowthe exhaust fan. The system is high in working automation degree, simple in structure, good in cleaning effect and high in application value.

Description

technical field [0001] The invention relates to the technical field of cuvette cleaning devices, in particular to an automatic cleaning system for cuvettes in laboratory processing. Background technique [0002] A cuvette is an instrument used for spectral analysis. It is mainly made of quartz powder. The cuvette is generally a cuboid. The bottom and two sides are ground glass, and the other two sides are made of optical glass. made. [0003] In the actual chemical analysis process, the cuvette needs to be thoroughly cleaned after each use to avoid the influence of the previous result on the next test. At present, the cleaning of cuvettes is mainly carried out by manual hand washing. For example, the Chinese invention patent with the publication number CN107790433A discloses a cuvette automatic cleaning device, including a cuvette, a water inlet pipe, an outlet pipe and an ultrasonic device; the water inlet pipe and the outlet pipe extend into the cuvette sample chamber; ...

AI Technical Summary

Problems solved by technology

The cleaning device is simply provided with a water inlet pipe and a water outlet pipe on the cuvette, and uses an ultrasonic device installed at the lower end of the cuvette to perform ultrasonic-assisted vibration to achieve the purpose of cleaning. The degree of automation of its work is still not high, and the cleaning method It is relatively simple and cannot achieve the purpose of multiple cleaning, so the cleanliness of cleaning needs to be further improved
