The using method of the device that this utility model provides is as follows: (1) closes valve, according to required leach extraction method, pedotheque is put in agitator (drum), add deionized water, solution is stirred by turn on agitator, use pH meter and oxidation reduction potential determination instrument to measure and pH and Eh of recording solution, and require to be adjusted to required pH value by pH regulator device (acid buret) according to leach extraction method.Regulation mixing speed continuous stirring according to demand, uses aerator regulation aeration flow to carry out aeration, measures and recording solution pH and Eh according to timing node.(2) agitator and aerator and pH meter and oxidation reduction potential determination instrument are closed, solution left standstill is precipitated 10-15min, after making solid liquid interface substantially be layered, opens valve, treat that major part liquid flows out under gravity, enter the first lixiviating solution determining heavy metals stage.(3) if extracted many times, close valve, and require operation according to extracted many times operation, record related data.(4), after use terminates, each device is taken out and cleans, unscrew spiral attachment cap, drum is separated with keg (test bucket), take out rubber ring pad and nylon wire, clean in the lump with drum keg and other devices.
The beneficial effects of the utility model are embodied in the following aspects:
1., in prior art, for ensureing the precision of experiment, when extraction processes, after pH regulator and pH, Eh measure the soil suspension stratification being required for extracted, measure supernatant.This utility model agitator tank uses the mode that big keg connects, it is simultaneously connected with place and uses nylon wire, thus reach the purpose isolated soil suspended particulate substance, allow liquid to pass through, can be with the real time measure soil pH, Eh value during making stirring and leaching, decrease the solution left standstill time, it is prevented effectively from soil suspension the mensuration of pH, Eh is disturbed, extends the instrument such as pH meter service life, accelerate pH regulator finding speed.
2. owing to devising rubber ring and interface demountable structure so that the cleaned and changed convenience of device.
3. devise outlet structure, it is to avoid supernatant topples over the tedious steps such as transfer, facilitates the operation of extracted many times mode.
4. device passes through aeration and impeller alr mode, accelerates extracting effect, decreases extraction time.
5. the stirring in device, aeration, pH regulator are the most controllable, can regulate according to demand, be suitable for the pre-treatment of multiple leach extraction method.
