Principle of operation

Opening the cover 21, adding the mixture of waste liquid and extract liquid into the extraction box 19, adding the strip liquid such as sulfuric acid into the raw material box 20, after the liquid in the cover 21 is layered, distinguishing the layered position of the two liquids through the detection strip 23, starting the telescopic pipe 30 to extend into the bottom of the layer where the oil-containing copper ion solution is located, starting the pump body 27, enabling the solution to enter the pump body 27 after passing through the telescopic pipe 30, the liquid suction pipe 29 and the pump body access pipe 28, opening the connecting pipe 22 below the extraction box 19 and the raw material box 20, and putting the solution and the strip liquid into the barrel body 16.

After the solution and the strip liquor enter the barrel 16, the connecting pipe 22 is closed, the motor 34 is started, the motor 34 drives the power screw 38 to rotate, but the initial rotation is a short-distance reciprocating rotation, the power screw 38 rotates to drive the connecting rod 41 to rotate, and the connecting rod 41 drives the layer-changing stirring block 42 to stir the two solutions so as to transfer copper ions into the strip liquor to form solutions such as copper sulfate and the like, so that the copper simple substance can be conveniently extracted subsequently.

When the connecting rod 41 rotates clockwise in the direction from top to bottom, the layer-changing stirring block 42 with the liquid channel 44 opening downward does not suck liquid and only plays a role of lateral stirring, the layer-changing stirring block 42 with the liquid channel 44 opening upward enters the layer-changing stirring block 42 through the liquid inlet 43 and then is thrown out upward through the liquid channel 44, the liquid exchange between the lower layer and the upper layer is completed, the liquid in the lower layer is sent into the upper layer for reaction, when the connecting rod 41 rotates counterclockwise, the layer-changing stirring block 42 with the liquid channel 44 opening upward does not suck liquid and only plays a role of lateral stirring, the layer-changing stirring block 42 with the liquid channel 44 opening downward enters the layer-changing stirring block 42 through the liquid inlet 43 and then is thrown out downward through the liquid channel 44, the liquid exchange between the upper layer and the lower layer is completed, the liquid in the upper layer is sent into the lower layer for reaction, the upper liquid is fully reacted.

After a period of stirring, the motor 34 drives the power screw 38 to rotate in the same direction, because the guide rod 39 is limited in the guide rod mounting sleeve 48, the power screw 38 rotates in the thread block 46, the thread block 46 drives the shell 45 to move downwards along the guide rod 39, the guide rod 39 slides in the guide rod mounting sleeve 48, the shell 45 moves downwards to drive the gear 47 to rotate on the power screw 38, the gear 47 rotates to drive the ratchet 49 to rotate, the ratchet 49 drives the driving gear 50 and the driving shaft 51 to rotate, the driving shaft 51 drives the liquid pumping turbine 53 to rotate, the liquid pumping turbine 53 pumps the liquid suction cavity 52 below the baffle plate 55 to negative pressure, gas enters the liquid pumping turbine 53 through the gas inlet 58 and is finally discharged by the liquid outlet one-way valve 54, when the shell 45 moves to lower layer liquid before the connecting rod 41 moves, the pressure in the liquid suction cavity 52 reaches the set value of the pressure valve 59, the pressure valve 59 opens, the liquid suction cavity 52 starts to suck the lower layer liquid, and the lower layer liquid is fully reacted.

When the liquid at the lower layer enters the liquid suction cavity 52 and reaches the float 57, the float 57 floats to block the air inlet 58, the liquid cannot enter the upper side of the baffle 55, when the shell 45 moves to the connecting rod 41, the motor 34 drives the power screw rod 38 to rotate reversely, the shell 45 is brought back to the upper side, the ratchet wheel 49 stops being meshed with the gear 47, the pressure valve 59 cannot reach a pressure set value and is closed, after the shell 45 moves to the upper layer of liquid, the ejector rod 35 pushes the sliding block 60, the through hole 61 is aligned to the liquid inlet 63, the liquid collected in the liquid suction cavity 52 is sprayed from the upper layer of liquid, short-distance reciprocating stirring before repeating is repeated, after the sliding block 60 is separated from being contacted with the ejector rod 35, the pressure valve 59 pushes the sliding block 60 back to reset until the reaction is sufficient, and the copper ion reaction is completely finished.

During the previous short-range reciprocating stirring, each time the ejector rod 35 rotates reversely, the ejector rod 35 will push the sliding block 60 to release the pressure in the liquid suction cavity 52, so as to avoid collecting lower-layer liquid, after the reaction, the light-emitting lamp 36 is turned on, the sensor 37 receives the signal of the light-emitting lamp 36, the fourth valve 40, the first valve 24 and the second valve 25 are selectively opened, two kinds of liquid are respectively discharged through the liquid discharge pipe 18, the liquid left in the extraction box 19 can be discharged into the barrel 16 after the reaction in the lower part is finished and various kinds of liquid are all emptied, and finally the liquid is discharged through the liquid discharge pipe 18.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
