Description

Zinc chloride recoverer in floating and sinking test Technical Field The invention relates to the technical field of coal mine floating and sinking tests, in particular to a zinc chloride recoverer in a floating and sinking test. Background The floating and sinking test, also called density composition analysis or heavy liquid separation test, is one of the most basic and critical analysis tests in the field of coal washing and selecting processing, usually uses zinc chloride (ZnCl 2) aqueous solution to prepare heavy liquid with different densities, and separates coal into different density grades by setting the heavy liquid with different densities, so as to determine the optimal separation density. In a floating test, the floating objects are fished out and drained, and the specific operation steps are that a fishing spoon is used for fishing the floating objects in a test barrel into a net bottom barrel, the net bottom barrel is obliquely placed on the barrel edge to filter out heavy zinc chloride liquid, in the process, the heavy liquid is easy to flow away from the side wall of the test barrel, the lost heavy zinc chloride liquid is difficult to recover due to high price of zinc chloride, so that great production waste is caused, the oblique placing barrel edge of the net bottom barrel occupies the barrel opening space and easily slips into the heavy liquid barrel, zinc chloride is splashed and wasted, zinc chloride belongs to a toxic reagent and has corrosiveness, and an aqueous solution of the zinc chloride is acidic, so that once the zinc chloride contacts a human body in the splashing process, the heavy liquid can cause irritation and cauterization injury to the skin and mucous membrane of the human body, and if the zinc chloride splashes into eyes, so that great medicament waste and great potential safety hazard still exist in the current test link.
