Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a chemical wastewater inspection sampling device. Background Art

[0002] The main source of chemical nickel wastewater is the cleaning water of chemical nickel electroplating solution. There are chelating agents and sodium hypophosphite in chemical nickel electroplating solution. The main components of this chemical nickel wastewater are hypophosphorous acid and chelated nickel, which correspond to the nickel content and phosphorus content in the electroplating wastewater treatment indicators. When testing chemical nickel wastewater, it is necessary to obtain multiple chemical nickel wastewater samples, so it is necessary to use a sampling device to take samples and then put them into beakers for testing. The existing sampling device is similar to a syringe, which sucks the chemical nickel wastewater into the tube and then puts it into multiple beakers. This method requires manual operation for both liquid extraction and liquid discharge, which is relatively inconvenient. Utility Model Content
