Embodiment Construction
[0021] In order to make those skilled in the art understand the present invention better, below in conjunction with Figure 1-5 , to further illustrate the present invention.
[0022] The control unit 1 controls the automatic sampling device 2 to extract the reagent, and mixes it with the water sample through the water sample filter 3. The mixture of the water sample and the reagent is stirred by the automatic stirring device 4, filtered through the water sample filter 3, and enters the detection device 5 for detection. .
[0023] The water sample filter includes an upper filter module 31, a filter membrane and a lower filter module 32; the upper filter module 31 and the lower filter module 32 are connected, and a filter membrane is arranged between the upper filter module 31 and the lower filter module 32.
[0024] The filter upper module 31 includes a pipe connection part 311 and an external thread connection part 312, and the external thread connection part 312 is provided...

Description
technical field [0001] The invention belongs to general physical or chemical methods or devices, and in particular relates to a device for automatic extraction of water samples. Background technique [0002] Water sample pretreatment is an important part of analysis and detection. When performing water quality analysis and determination, traditional water sample pretreatment adopts manual extraction and then static layered separation. After standing and stratifying, pick up the target object. Using this method to process water samples is labor-intensive, the operator directly contacts the reagents, and the toxic extract is likely to cause harm to the human body, and the manual operation has large errors and low precision, which cannot meet the requirements for batch analysis and real-time monitoring of water samples. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a device for automatic extraction of water samp...
