Problems solved by technology

[0002] Existing non-contact liquid level sensors include ultrasonic liquid level transmitters, radar liquid level transmitters, etc., but the price of liquid level sensors is relatively high, and infrared sensors are often used in laboratories to detect the liquid level of liquid medicine. In order to control the amount of liquid medicine, due to the different concentration and adhesion of various liquid medicines, it often happens that there is residual liquid in the pipeline and on the inner wall of the reactor when detecting the water outlet device, which cannot be detected by the infrared sensor. The volume of the residual liquid, and then the residual liquid slowly enters the reactor, which affects the dosage of the liquid medicine, and it is difficult to ensure the accuracy of the liquid medicine measurement

Abstract

The invention relates to a laboratory liquid medicine outlet device which comprises a mounting base, and a reaction kettle, a liquid storage tank, a liquid guide device, a detection device and a liquid suction mechanism which are arranged on the mounting base; the detection device is used for detecting the liquid outlet amount of liquid medicine, and the liquid guide device comprises a stand column, a mounting plate, a liquid guide mechanism, a cleaning mechanism, a rotating mechanism and a driving mechanism; the liquid guide mechanism comprises a liquid inlet pipe of the reaction kettle and aliquid outlet pipe of the liquid storage tank, the cleaning mechanism is used for pressing medicine liquid in the liquid inlet pipe into the reaction kettle, the driving mechanism drives the rotatingmechanism to rotate in the circumferential direction of the stand column, the stand column is sleeved with the rotating mechanism and the mounting plate, and the mounting plate is arranged above therotating mechanism. The mounting plate can move in the vertical direction in the length direction of the stand column. The first infrared detection mechanism and the second infrared detection mechanism are arranged to monitor the liquid outlet amount and the liquid inlet amount in real time, the accuracy of the detection device for detecting the dosage of liquid medicine is improved, and the liquid taking efficiency is improved.
