Description

Technical Field

[0001] The invention relates to the technical field of waste liquid recovery, in particular to a copper recovery device for producing copper-containing ferric chloride waste liquid. Background Art

[0002] A large amount of copper resources will be generated during the production process of copper-containing ferric chloride waste liquid. In order to effectively recycle and utilize it, chemical precipitation method is often used to recover copper. This method is mature in technology, simple to operate and low in cost. By adding chemical agents, copper ions are formed into insoluble precipitates, thereby efficiently separating and recovering copper resources.

[0003] The patent with application number CN202121872754.8 discloses a copper-containing waste liquid recovery device, including a base, a stirring mechanism and a filtering mechanism. A treatment box is fixedly connected to the top of the base, and a liquid inlet hopper is fixedly connected to the top of the treatment box. A water pump is installed on the top of the treatment box, and the right side of the water pump water inlet is fixedly connected to a water pipe whose bottom runs through the top of the inner wall of the treatment box. This not only avoids the pollution caused by direct discharge of copper-containing waste liquid, is beneficial to environmental protection, but also saves resources.

[0004] However, for some copper-containing waste liquids, such as copper-containing ferric chloride waste liquids, there are obvious stage differences in the precipitation of iron ions and copper ions during the process of adding precipitants and adjusting the pH value: when the pH value is adjusted to about 3.5, iron ions will be precipitated from the waste liquid first; and when the pH value is further adjusted to about 7, copper ions will begin to precipitate. In view of this characteristic, traditional equipment requires operators to first filter the iron ion precipitate, then manually disassemble and clean the filter device, and then filter and separate the copper ions. This step-by-step operation not only increases the complexity of manual intervention, but also leads to the interruption of the recovery process, seriously affecting the continuous operation efficiency of the equipment.

[0066] Furthermore, the worm 340 drives the shaft end worm wheel 540 to rotate together with the center wheel 530, and at the same time drives the transmission tooth 511 and the outer sleeve tooth 520 to rotate simultaneously. When the transmission tooth 511 rotates, it drives the inner ring 424 and the sleeve 421 to rotate at high speed, thereby throwing out the sediment on the filter plate 422, and through the scraper 560 under the outer sleeve tooth 520, the sediment is sent from the discharge hole 221 into the interior of one of the discharge pipes 160.

[0067] Finally, it should be noted that the drive motor 310 involved in the present invention is a general standard part or a part known to those skilled in the art, and its structure and principle are all known to those skilled in the art through technical manuals or conventional experimental methods.

The electrical connection between the electrical components is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the art.

[0068] When the copper recovery device for producing copper-containing ferric chloride waste liquid of the present invention is used, first, the copper-containing ferric chloride waste liquid is poured into the interior of the fixed tank 110 through the feed pipe 240 in the sealing mechanism 200, and a precipitant is added therein;

[0069] Then, the pH value of the solution is adjusted to 3.5, and after the iron ions are precipitated from the solution, the driving motor 310 in the driving device 300 is started to drive the driving shaft 320 to rotate, thereby driving the drawing tube 351 in the drawing part 350 to rotate;

[0070] At this time, the pulling tube 351 is located inside the worm 340 above the screw rod 411. The protrusion 353 on the pulling tube 351 extends to the inside of the slot 341 of the worm 340 under the elastic force of the first spring 354, thereby driving the worm 340 to rotate together, so that the rod end worm wheel 412 in the lifting part 410 rotates;

[0071] When the rod end worm wheel 412 rotates, the lead screw 411 is driven to move upward, and the outer ring 413 is driven to move upward as a whole, and then the centrifugal part 420 is driven to move together, until the top end of the inner ring 424 of the centrifugal part 420 is sleeved inside the transmission tooth 511, and then the driving motor 310 is turned off, and the inner extension block 512 of the transmission tooth 511 is extended to the inside of the annular wall groove 4240 under the elastic force of the second spring 513;

[0072] Next, the pull rod 352 is moved to drive the pulling tube 351 to move outside the driving shaft 320, so that the end of the pulling tube 351 extends to the inside of the worm 340 above the center wheel 530, and then the driving motor 310 is started again;

[0073] The worm 340 drives the shaft end worm wheel 540 to rotate together with the center wheel 530, and at the same time drives the transmission gear 511 and the outer sleeve gear 520 to rotate simultaneously. When the transmission gear 511 rotates, it drives the inner ring 424 and the sleeve 421 to rotate at high speed, and the sediment on the filter plate 422 is thrown out, and the scraper 560 under the outer sleeve gear 520 sends the sediment from the discharge hole 221 into the interior of one of the discharge pipes 160;

[0074] Afterwards, after the iron ion sediment is cleaned, the output direction of the driving motor 310 is changed, and the position of the pulling part 350 is reset, and the screw rod 411 is driven downward by the rod end worm gear 412 to reset the positions of the lifting part 410 and the centrifugal part 420;

[0075] When the pH value is adjusted to 7, the position of the rotating ring 220 is changed by the lever 230, and the discharge hole 221 is moved to the top of another discharge pipe 160, and the above operation is repeated to discharge the copper ion precipitate, and the precipitate is sent to the subsequent cleaning device to complete the recovery of copper in the waste liquid.
