Automatic water changing device in medicine detector

Abstract

The invention discloses an automatic water changing device in a medicine detector, and mainly relates to the field of medicine detection. The device comprises a water storage tank, a preheating tank,a water adding pump, a beaker and a water bath which are sequentially connected through pipelines, the beaker and the water bath are communicated with a three-way valve through a pipeline; a remainingconnector of the three-way valve is connected with a water discharging pump, one side of the water discharging pump is connected with a filtering device through a pipeline, one side of the filteringdevice is connected with a collecting tank through a pipeline, one side of the collecting tank is connected with a distilling device through a pipeline, and the distilling device is connected with a water storage tank through a pipeline. The device has the beneficial effects that pure water is obtained through the distillation device and then sent into the water storage tank, more standby water sources do not need to be carried, repeated utilization of waste water after an experiment can be achieved, and the device is convenient to use for experiments on a rapid detection vehicle.

Description

technical field [0001] The invention relates to the field of drug testing, in particular to an automatic water changing device in a drug testing instrument. Background technique [0002] At present, all drug testing instruments (generally referred to as drug testing instruments) are equipped with water baths, and in the process of drug testing, the amount of experimental water is relatively large, and the frequency of water changes is also relatively large. Existing water bath heating experiments all use manual water change, so the operation procedures of the experimenters are very complicated, especially when the experiment is carried out in the quick inspection vehicle, the environmental conditions cannot be used for manual water change. Therefore, problems such as long experiment time and high labor intensity of operators are brought about. [0003] Moreover, the space in the quick inspection vehicle is limited, and it is inconvenient to equip the existing automatic wate...

AI Technical Summary

Problems solved by technology

The existing water bath heating experiments all use manual water change, so the operation procedures of the experimenters are very complicated, especially when the experiment is carried out in the quick inspection car, the environmental conditions cannot be used for manual water change

Therefore, it brings problems such as long experiment time and high labor intensity of operators.

[0003] Moreover, the space in the quick inspection vehicle is limited, and it is inconvenient to equip the existing automatic water exchange device with a large-capacity water storage tank, so the experimental water in the water storage tank will be quickly consumed, especially when the amount of drug detection is large , it is necessary to place some buckets on the quick inspection car to add water to the water storage tank, which will occupy the space in the quick inspection car and consume a lot of water, and the water used in the drug testing experiment will contain drug residues or dissolve There are medicinal ingredients, which cannot be completely filtered by filtration. The filtered water will still have medicinal ingredients dissolved in it. If it is used directly in the experiment, it will affect the experimental results. Therefore, it is impossible to repeat the water that was replaced after the experiment. Utilization, it is not convenient for the use of the test on the quick inspection vehicle
