Description

Rhodium refining closed extraction equipment

technical field

The utility model relates to extraction equipment, in particular to rhodium refining airtight extraction equipment.

Background technique

There are six elements in the platinum group metals, including platinum, palladium, rhodium, iridium, ruthenium, and osmium. Generally, platinum group metals exist in solution in the form of complex anions, and base metals exist in solution in the form of hydrated cations. Cation exchange is an important means for separating platinum group metals from base metals. Therefore, in the rhodium refining process, the separation of rhodium and base metals is relatively easy. Firstly, cation exchange is used to separate base metals to obtain qualified base metals in rhodium solution, and then solvent extraction technology is used to separate other platinum group metal impurities.

Platinum group metals have similar chemical properties and are difficult to separate from each other. Generally, osmium and ruthenium are separated by oxidative distillation first, then platinum and palladium are separated by solvent extraction, and finally rhodium and iridium are separated.

During the rhodium refining process, solvent extraction technology is used to separate and purify rhodium. Generally, diisoamyl sulfide (S201) is used to extract palladium, tributyl phosphate (TBP) to extract platinum and iridium, and finally rhodium is refined. Due to the concentration of metal impurities in the solution Different, often need to use different separation methods and equipment.

The existing extraction equipment for separating and purifying rhodium has poor corrosion resistance, large vibration, short service life, inconvenient operation, high labor intensity and small scale.

Contents of the invention

The utility model aims at the deficiencies of the prior art, and provides a rhodium refining airtight extraction device, which can effectively solve the problem of separating and recovering rhodium from rhodium-containing waste catalyst, rhodium waste residue and rhodium waste liquid.

Rhodium refining airtight extraction equipment, including tank body, tank cover and bracket, the tank body is upright cylindrical and installed vertically on the bracket, there is a discharge port at the bottom, there is a discharge valve on the discharge port, and there is a heating jacket outside the tank ;The tank cover has a feed inlet, a measuring port, an air pressure adjustment port and a titanium stirrer. The feed inlet is usually closed with a glass plug and opened when it is used. There is an air pressure regulating valve on the air pressure adjustment port; the tank body and the tank cover are connected by a connecting device As a whole, there is an automatic temperature controller on the bracket, and the temperature measuring probe connected with the automatic temperature controller extends into the tank from the measuring port, and the power line of the heating jacket is connected with the automatic temperature controller.

When working, close the discharge valve, connect the hose to the feed port, open the air pressure regulating valve, and draw a vacuum from the air pressure regulating port to generate internal negative pressure in the tank. Inhale into the tank, then stop vacuuming to make the air pressure in the tank be normal pressure, remove the hose at the inlet, and then close it with a glass plug, set the temperature of the automatic temperature controller, and control the material in the tank through the heating jacket Heating is carried out, and the agitator is turned on to stir the materials in the tank. After the reaction is completed, stop the agitator and the automatic temperature controller, open the discharge valve to discharge the material, clean the tank and proceed to the next process.

The rotational speed of the agitator is 40-200 rpm.

The connecting device is a bolt or screw connection.
