Abstract
The invention discloses a crystal centrifuge for producing potassium aurous cyanide, which aims to solve the technical problem that the traditional classifying centrifuge cannot continuously produce. According to the invention, crystals are separated in a grading way through the inner drum wall and the outer drum wall, and then the crystals are discharged out of the centrifugal machine through the cooperation of the rotating upper annular plate, the rotating lower annular plate and the rotating material guide plate.
Description
Technical Field
The invention relates to the technical field of potassium aurous cyanide production equipment, in particular to a crystal centrifuge for potassium aurous cyanide production.
Background
The potassium aurous cyanide is white crystal and is a double salt formed by aurous ions and cyanide ions. Dissolving in water, slightly dissolving in ethanol, insoluble in diethyl ether, being easy to wet and extremely toxic, gold potassium cyanide is a highly toxic chemical, the toxicity is basically the same as potassium cyanide, and the lethal dose is about 0.1 g. Preparation: the pure gold reacts with aqua regia, filtered, concentrated hydrochloric acid is added to remove nitrogen oxides, then the pure gold reacts with potassium cyanide, and then the pure gold is crystallized to obtain the finished product.
The centrifuge is an indispensable device for separating gold potassium cyanide crystals. Centrifugal machines are various, but the centrifugal machines are basically the same in distance, and the rotary drum is used for driving crystals to rotate so that the crystals are separated from a solution under the action of centrifugal force. The Chinese patent with the bulletin number of CN201866240U discloses a classifying centrifuge, the classifying centrifuge comprises a centrifuge shell, an air inlet is arranged at the left part of the upper end of the centrifuge shell, an air outlet is arranged at the right part of the upper side of the centrifuge shell, an exhaust fan is arranged on the air outlet, the exhaust fan is connected with a waste gas treatment device through a pipeline, a supporting leg is arranged at the lower end of the centrifuge shell, a supporting plate is arranged at the middle part of the supporting leg, a damping motor is arranged at the upper part of the supporting plate, an output shaft of the motor is connected with a rotary disc arranged inside the centrifuge shell through a rotary shaft, and a first centrifugal layer, a second centrifugal layer and a third centrifugal layer are arranged at the upper end of the rotary disc.
The centrifugal machine realizes the grading separation of crystals with different particle diameters by using the first centrifugal layer, the second centrifugal layer and the third centrifugal layer which are coaxially arranged, but due to the action of centrifugal force, part of crystals with large particle diameters in the first centrifugal layer can easily cross the first centrifugal layer to be mixed with crystals with medium particle diameters in the second centrifugal layer, and part of crystals with medium particle diameters in the second centrifugal layer can easily cross the second centrifugal layer to be mixed with crystals with small particle diameters in the third centrifugal layer, so that the grading effect of the crystals is poor. Meanwhile, as the centrifugal machine is an intermittent centrifugal machine, namely after the separation of liquid and crystals is completed, the separation operation is stopped, and the top cover is opened to take out the crystals with various particle sizes; the centrifuge is extremely dangerous to toxic substances such as potassium aurous cyanide, so that only a continuous centrifuge can be used, in other words, the existing centrifuge with the classification function is not suitable for producing the potassium aurous cyanide.
Secondly, because of continuous production, the filter holes on the rotary drum of the existing continuous centrifugal machine are easy to be blocked, and the filter performance of the rotary drum is slowly reduced after the filter holes are blocked, so that the production efficiency is seriously affected.
