Description
Technical field
The utility model relates to the reagent sampler, especially relates to the liquid reagent quantitative sampling device that a kind of energy accurate quantification extracts liquid reagent.
Background technology
In the analysis to measure of chemical analysis, liquid reagent sampling requirement precision is higher, if precision is not enough, will have a strong impact on analytical accuracy, and a good quantitative sampling device is very important to analysis result.The device that liquid reagent is carried out quantitative sampling in the market mainly contains following three kinds:
One, adopt fixed displacement pump to take a sample.By an inductor amount of reagent is controlled, to reach the purpose of quantitative sampling.The main deficiency of the method is: can only measure the reagent by inductor, the residual reagent in the sampling system pipeline is many, can't accomplish accurate sampling;
Two, adopt peristaltic pump to take a sample.Drive peristaltic pump by a stepper motor, reach the purpose of quantitative sampling by the rotating speed of control peristaltic pump.The shortcoming of this method is: when running, can produce a stream of pulses, and bigger to the sampling result error;
Three, adopt syringe to sample.Drive syringe, slide block by a stepper motor, the pulsed quantity of exporting by the control motor achieves the goal.The shortcoming of this method is: the cost height, and the drive unit complexity, personnel require height to working service.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of energy accurate quantification to extract the liquid reagent quantitative sampling device of liquid reagent.
The utility model is to realize by following technical measures, a kind of liquid reagent quantitative sampling device, comprise the measuring fixed amount pipe, liquid pump and be connected the liquid pump discharge and can stretch into feed tube in the measuring fixed amount pipe, described measuring fixed amount pipe pipe sidewall requires quantitative position to be provided with the run-down pipe that is communicated with the measuring fixed amount pipe, described measuring fixed amount pipe bottom liquid outlet is connected with solenoid valve, the outlet of this solenoid valve is connected with ascending pipe, described measuring fixed amount pipe pipe sidewall requires quantitative position to be provided with liquid level sensor, described liquid pump, solenoid valve and liquid level sensor are connected electrically on the controller.
The preferred peristaltic pump of liquid pump wherein, the preferred PLC controller of controller.
The course of work of the present utility model is: the liquid reagent that the liquid pump extracts appointment injects the measuring fixed amount pipe through feed tube, when liquid level sensor detects liquid reagent when measuring fixed amount Guan Zhongyi reaches predetermined altitude, liquid level sensor detects and gives controller with this signal, controller receives behind the signal at first, and the controlling liquid pump quits work, and postpone a period of time, after treating that excessive reagent overflows from run-down pipe, the controller opens solenoid valve with in the measuring fixed amount pipe the liquid reagent of accurate quantification inject reaction tank from ascending pipe.Therefore the utlity model has advantages such as cost is low, simple in structure, easy to maintenance, continuous working for a long time.
