Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, and more specifically to an intermittent online safe sampling device for chemical wastewater. Background Art

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water, etc. discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. After being treated, chemical wastewater can be discharged into the natural environment, but it is still necessary to take samples regularly during the discharge process to verify whether it meets the discharge standards.

[0003] An online sampling valve is a common sampling device, which can be installed in a wastewater discharge pipeline. When needed, the valve can be opened to extract wastewater samples from the pipeline. Since it can be opened and taken at any time, intermittent sampling can be performed, that is, sampling is performed at regular intervals. At present, most common online sampling valves use glass bottles to store samples. When sampling, the mouth of the glass bottle is screwed into the bottom of the valve body, and then the valve is opened to take samples. However, the threaded connection means that only a single size of glass bottle can be used, and glass bottles have a variety of different sizes depending on the sampling volume. If the size of the glass bottle is different from the size of the threaded mouth of the online sampling valve, it cannot be connected, and the applicability is insufficient. Therefore, it is urgent to design an intermittent online safety sampling device for chemical wastewater to solve the above problems. Utility Model Content
