Description

Technical Field

[0001] The invention relates to the technical field of metal recovery, in particular to a leaching device for zinc-containing smoke. Background Art

[0002] Leaching refers to the process of extracting soluble substances from solids with chemical solvents, also known as leaching. The chemical solvent used for leaching is called a leaching agent, the solution obtained after leaching is called a leachate, and the remaining solid is called a residue. The leaching effect is expressed by the leaching rate, that is, the percentage of soluble substances in the solid dissolved in the leachate. The solids leached in hydrometallurgy are metallurgical intermediates such as ores, concentrates, roasted sand or matte, smoke and anode mud. The leaching of zinc-containing smoke requires mixing with choline chloride-urea leaching agent liquid and water, and is mostly completed using a leaching device. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a method and device for leaching zinc-containing smoke from a steel mill with announcement number: CN113234934B.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1) The present invention adopts a rotating drum and a storage box. When the leaching device containing zinc dust is actually used, the outer wall of the collection box is first penetrated with an external anode and an external cathode, and then the controller is used to open and close the three sets of electronic metering valves, and the annular electromagnet, water pump, temperature sensor, drive motor and electric heating rod are powered on to work at the same time. Water, choline chloride-urea leaching agent liquid and zinc dust can enter the interior of the rotating drum through the four-way pipe. When the amount of entry reaches the preset value of the three sets of electronic metering valves, a signal can be sent to the controller, and the controller closes the three sets of electronic metering valves. At the same time, the output end of the drive motor can drive the pinion to rotate. Since the pinion and the outer gear ring are meshed with each other, the rotating pinion can drive the outer gear ring to rotate, and the rotating outer gear ring can drive the rotating drum to rotate. The annular electromagnet is powered on, which can make multiple sets of limit plates move toward the annular electromagnet.

When one end of the liquid outlet pipe is located directly above the feed hopper, the annular electromagnet is powered off. The plurality of telescopic springs can respectively push the plurality of piston plates. The plurality of piston plates can push the mixture inside the plurality of storage boxes back into the rotating cylinder. The control valve is opened and closed. The mixture inside the rotating cylinder can enter the interior of the feed hopper through the liquid outlet pipe.

[0019] 3) The present invention adopts an air charging pipe. Before the zinc fume leaching device is actually used, the controller is used to make the air pump and the servo motor work. The air can enter the interior of the installation box through the two sets of filter baskets. The air inside the installation box can enter the interior of the four-way pipe through the three-way pipe and the air charging pipe. Finally, the air can be filled into the interior of the rotating cylinder. The output end of the servo motor can drive the main gear to rotate. The rotating main gear can drive the two sets of driven gears to rotate. The rotating two sets of driven gears can rotate the two sets of filter baskets through the two sets of rotating pipes. The adsorbed substances on the surfaces of the two sets of filter baskets will be thrown off by the centrifugal force, and the interior of the rotating cylinder will be filled with air. The air can enter the interior of the multiple storage boxes through the multiple connecting pipes. When the multiple limit plates contact the inner wall of the annular electromagnet, the air pump stops. When there is a leak inside the rotating cylinder, the multiple telescopic springs can push the multiple piston plates under their own elastic force to push the air inside the multiple storage boxes back to the rotating cylinder through the multiple connecting pipes. The operator can determine whether there is a leak in the rotating cylinder by observing the position of the multiple limit plates. The air-filled pipe is provided with an airtightness detection structure, which can detect whether there is a leak in the mixing space, thereby ensuring the safety of the leaching device containing zinc smoke.

[0048] In this implementation scheme: the controller control circuit can be implemented through simple programming by technicians in this field, which is common knowledge in the field. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0049] Working principle: When the zinc-containing smoke leaching device is actually used, the outer wall of the collection box 11 is first penetrated with an external anode and an external cathode, and then the controller is used to open and close the three sets of electronic metering valves, and the annular electromagnet 10, the water pump 13, the temperature sensor 24, the drive motor 26 and the electric heating rod 30 are powered on to work. Water, choline chloride-urea leaching agent liquid and zinc-containing smoke can enter the interior of the rotating cylinder 2 through the four-way pipe 8. When the amount of entry reaches the preset value of the three sets of electronic metering valves, a signal can be sent to the controller, and the controller closes the three sets of electronic metering valves. At the same time, the output end of the drive motor 26 can drive the pinion 27 to rotate. Since the pinion 27 and the outer gear ring 28 are meshed with each other, the rotating pinion 27 can drive the outer gear ring 28 to rotate, and the rotating outer gear ring 28 can drive the rotating cylinder 2 to rotate, and the annular electromagnet 10 is energized to make the multiple groups of limit plates 19 move toward the annular electromagnet 10, and the multiple groups of limit plates 19 can make the multiple groups of piston plates 18 move away from each other through the multiple groups of moving rods 17. In this process, the multiple groups of piston plates 18 can respectively squeeze the multiple groups of telescopic springs 20, and the mixture inside the rotating cylinder 2 will enter the interior of the multiple groups of storage boxes 22 through the multiple groups of connecting pipes 16 in turn, the electric heating rod 30 can heat the mixture through the shaft tube 29, and the multiple groups of stirring blades 31 can stir the mixture. When one end of the liquid outlet pipe 23 is located directly above the feed hopper 12, the annular electromagnet 10 is powered off, and the multiple groups of telescopic springs 20 can respectively push the multiple groups of piston plates 18, and the multiple groups of piston plates 18 can push the mixture inside the multiple groups of storage boxes 22 back to the inside of the rotating cylinder 2 The control valve is opened and closed, and the mixture inside the rotating cylinder 2 can enter the interior of the feed hopper 12 through the liquid outlet pipe 23. The rotating cylinder 2 and the storage box 22 can make the zinc-containing smoke, choline chloride-urea leaching agent liquid and water fully mixed, thereby improving the mixing efficiency of the leaching device for zinc-containing smoke. At the same time, according to the above operation, the mixed leachate and the leaching residue can fall into the interior of the filtering square tube 9 through the feed hopper 12. The controller is used to make the output ends of the two groups of forward and reverse motors 33 rotate synchronously through the synchronous controller. The two groups of winding disks 34 rotating synchronously can make the three groups of piston blocks 45 move left or right. During the left and right movement of the three groups of piston plates 18, the leachate can enter the interior of the collecting box 11 through the two groups of filter screens 35. At the same time, the three groups of piston plates 18 can push out the leached residue inside the filter square tube 9, and use the controller again to energize the external anode and the external cathode, and perform electrolysis operation on the zinc-containing leaching solution entering the collecting box 11. When the water pump 13 is working, the zinc-containing electrolytic solution can be extracted through the suction tube 14, and the filtered leached residue can be cleaned through the set filter square tube 9 without stopping the filtering work, which brings convenience to the cleaning of the leached residue of the leaching device containing zinc smoke. At the same time, before actually using the leaching device containing zinc smoke, first use the controller to make the air pump 36 and the servo motor 39 work, and the air can enter the interior of the installation box 38 through the two groups of filter baskets 42. The air inside the installation box 38 can enter the interior of the four-way pipe 8 through the three-way pipe 37 and the charging pipe 15, and finally the air can be filled into the interior of the rotating cylinder 2.The output end of the servo motor 39 can drive the main gear 40 to rotate, and the rotating main gear 40 can drive the two sets of driven gears 43 to rotate. The two sets of driven gears 43 can rotate the two sets of filter baskets 42 through the two sets of rotating tubes 41. By using the centrifugal force, the adsorbed materials on the surfaces of the two sets of filter baskets 42 will be thrown off, and the air inside the rotating cylinder 2 can enter the interior of the multiple sets of storage boxes 22 through the multiple sets of connecting tubes 16. When the multiple sets of limiting plates 19 contact the inner wall of the annular electromagnet 10, the air pump 36 is stopped. When there is a leak inside the rotating cylinder 2, the multiple sets of telescopic springs 20 can be acted upon by their own elastic force. The multiple sets of piston plates 18 can be pushed back to the rotating cylinder 2 through the multiple sets of connecting tubes 16. The operator can judge whether there is a leak in the rotating cylinder 2 by observing the position of the multiple sets of limiting plates 19. The air-tightness detection structure provided by the set air-filling tube 15 can detect whether there is a leak in the mixing space, which guarantees the safety of the use of the zinc fume leaching device.
