Quantitative sampling device for TDS (Total Dissolved Solids) water quality testing

Abstract

The invention discloses a quantitative sampling device for TDS (Total Dissolved Solids) water quality testing, which comprises a base, a cylinder body, a motor, a collecting tank, a TDS tester, and asampling chamber; the sampling chamber is fixedly mounted on the upper end of the base, and the motor is arranged on the upper end of the sampling chamber; a movable plate is slidably arranged in thesampling chamber, and both ends of the movable plate are slidably connected with slideways arranged on the side walls of the sampling chamber; the cylinder body is arranged on the left side of the sampling chamber, and a piston is slidably arranged inside the cylinder body; a controller is arranged on the front end of the base, a collecting tank is arranged at the right end of the base, and the TDS tester is arranged on the right side of the upper end of the base. According to the invention, the arranged movable plate moves downwards to press a press switch, so that the motor stops operating,as a result, the piston in the cylinder body stops pumping, quantitative sampling is realized, and the accuracy of a test result is improved. Arranged agitating vanes can effectively prevent particulate matter in a sample from settling to affect a test result. The quantitative sampling device has the advantages of high automation degree, simplicity in operation and high practicability.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a quantitative sampling device for TDS water quality detection. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, not only between countries, but also between differ...

Problems solved by technology

[0003] The general sampling device for TDS water quality testing uses manual sampling, and then puts it into the detection dish for detection. The degree of automation is low, and manual sampling cannot be accurately quantitatively selected, resulting in errors in the detection process and affecting the detection effect.
