Detection instrument capable of preventing cross contamination

Abstract

The invention provides a detection instrument capable of preventing cross contamination. The detection instrument comprises an instrument upper body, a detection button and a numerical value display screen, the detection button is fixedly installed on the left side wall of the instrument upper body, the numerical value display screen is fixedly installed on the outer side wall of the instrument upper body, the lower side wall of the instrument upper body is fixedly connected with an instrument lower body, the inner wall of the lower side of the instrument lower body is fixedly connected with a filter screen, and the outer side wall of the instrument lower body is fixedly connected with a motor fixing frame. Through cooperation of a motor, a water pumping wheel, a spring, a rubber sealing ring, a detection probe and a barrier cleaning plate, automatic sampling and automatic detection functions of sewage are realized by utilizing water flow impact force and acting force of the spring, so that the detection efficiency of sewage detection and the safety of operators in the operation process are improved, in addition, the cleaning, sealing and dust prevention effects on the detection probe are realized by utilizing the return driving of the spring, and the cross contamination of the instrument is avoided.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a detector capable of preventing cross-contamination. Background technique [0002] With the rapid development of my country's industry, more and more sewage is discharged from industrial production. The sewage discharged after the end of chemical production can lead to the lack of oxygen in the river water, resulting in the death of microorganisms that need oxygen. It is the existence of these aerobic microorganisms , so it can decompose organic matter and maintain the self-purification ability of rivers. After they die, they will cause rivers to turn black, become smelly, and accumulate toxins. Most organic chemicals are toxic, and they will poison or poison dead water when they enter rivers Biological, thus causing ecological damage, it can be seen that close detection of sewage discharge is particularly important in chemical production. [0003] After searching, the document...

Problems solved by technology

[0004] In the past testing instruments, the steps of taking water, testing and pouring water are usually used for testing operations. During this process, most of the testing samples are taken manually. Not only the steps are cumbersome, but also when there are improper operations, Chemical waste liquid will also cause certain damage to the human body. In addition, after the use of the previous detection instruments, the detection probe needs to be cleaned manually, but there are cases where the operator forgets to clean up due to negligence, which will affect the water quality of chemical sewage in the future. Data detection, in order to solve the above problems, a detection instrument that can prevent cross-contamination is proposed
