Description

Technical Field

[0001] The present invention relates to the field of chemical processing equipment, and in particular to equipment for recovering and processing copper extraction residual liquid and a process thereof. Background Art

[0002] The extract residue produced by copper extraction enters the slurry tank for leaching. After multiple cycles of enrichment in the slurry tank, the copper extraction residue enters the sedimentation tank and is purified and removed by using a precipitant. A combined method consisting of a goethite method and an oxidative hydrolysis method is used to remove impurities, so that impurities such as iron in the solution are hydrolyzed to form precipitates and easily filterable filter residues. The purification adopts a continuous operation, and then the filter residue is pressed and the residue liquid is separated from the filter residue. The cake-like filter residue obtained after pressing needs to go through a washing process. After the residual residue liquid in the filter residue is washed out, it is transferred to a temporary storage for storage. In this process, multiple processing steps are required to obtain the filter residue precipitate in the copper extraction residue, and the steps are cumbersome.

[0003] In addition, during the filter press process of the precipitate in the copper extraction residual solution, if the thickness of the filter residue formed after the filter press is too thick, the filter residue needs to be additionally broken up for washing when the filter residue is washed in the later stage. After washing the filter residue, the filter residue needs to be compressed back into a cake shape again, thereby affecting the work efficiency of the entire copper extraction residual solution recovery and treatment.

[0056] Filter pressing treatment of this copper extraction residual liquid recovery and treatment equipment:

[0057] The inlet end of the liquid inlet pipe 21 is connected to an external copper extraction residual liquid conveying device, and the outlet end of the liquid discharge pipe 22 is connected to an external copper extraction residual liquid recovery device.

[0058] After the external copper extract residual liquid conveying equipment pours the copper extract residual liquid into the sedimentation tank 2 through the liquid inlet pipe 21, a precipitant is added to the sedimentation tank 2 to allow the copper extract residual liquid to form a precipitate inside the sedimentation tank 2. After the precipitation of the copper extract residual liquid inside the sedimentation tank 2 is completed, the precipitate formed from the copper extract residual liquid gathers at the bottom of the sedimentation tank 2.

[0059] Then the telescopic end of the first cylinder 51 pushes the left pressure rod 41 to move to the right along the sedimentation chamber 2 through the first push block 52, and the left pressure rod 41 drives the left-rotating pressure plate 42 to move to the right. At the same time, the telescopic end of the second cylinder 71 pushes the right pressure rod 61 to drive the right-rotating pressure plate 62 to move to the left along the sedimentation chamber 2, so that the left-rotating pressure plate 42 and the right-rotating pressure plate 62 will push the sediment gathered at the bottom of the sedimentation chamber 2 toward the middle during the process of moving toward each other.

[0060] When the sediment is pushed into the filling assembly on the left side of the right-hand pressure plate 62, the sediment gathers at the inner bottom of the filling assembly. At this time, the first slot 421 of the left-hand pressure plate 42 is plugged into the ridge 311 of the adjacent annular gear plate 31, and the second slot 621 of the right-hand pressure plate 62 is also plugged into the ridge 311 of the adjacent annular gear plate 31. Then the first cylinder 51 and the second cylinder 71 continue to drive the left-hand pressure plate 42 and the right-hand pressure plate 62 to move toward each other, allowing the left-hand pressure plate 42 and the right-hand pressure plate 62 to continue to squeeze the sediment in the filling assembly. At the same time, the drive motor 32 adjacent to the annular gear plate 31 connected to the left-hand pressure plate 42 starts to run, and the output shaft of the drive motor 32 drives the connected spur gear 33 to rotate, and the spur gear 33 meshes with the connected annular gear plate 31 and drives it to rotate, and the annular gear plate 31 drives the left-hand pressure plate 4 through the ridge 311 2 rotates, the left-hand pressure plate 42 drives the left turntable 44, the dial plate 45, the pressure ring 46, the spring member 47 and the inserting plate 48 to rotate through the receiving groove 422. At the same time, the telescopic end of the first electric push rod 53 drives the second push block 54 to move rightward, and the second push block 54 drives the entire dial assembly to move rightward, so that the left turntable 44, the dial plate 45, the pressure ring 46, the spring member 47 and the inserting plate 48 are pushed to the right, so that the left-hand pressure plate 42 squeezes the sediment in the filling assembly to the right. At the same time, the rotating dial plate 45 continuously pushes the sediment at the bottom upward, so that the height of the sediment is continuously increased until the sediment is flattened inside the filling assembly and is squeezed and clamped in the filling assembly by the left-hand pressure plate 42 and the right-hand pressure plate 62. The first cylinder 51, the second cylinder 71 and the drive motor 32 stop working, and the sediment is filtered into a cake-shaped filter residue.

[0061] Afterwards, the copper extraction residual liquid that has completed the filtration treatment in the sedimentation chamber 2 is discharged to the external copper extraction residual liquid recovery equipment through the drain pipe 22, thereby completing the pressure filtration treatment of the filter residue and the recovery treatment of the copper extraction residual liquid.

[0062] Washing treatment of this copper extraction residual liquid recovery and treatment equipment:

[0063] The inlet end of the pipe 641 is connected to a spray liquid delivery device, and the outlet end of the drain pipe 22 is connected to a waste liquid recovery device.

[0064] After completing the filtration treatment of the filter residue and the recovery treatment of the copper extraction residual liquid, the telescopic end of the second electric push rod 73 pushes the third push block 74 to move to the left, and the third push block 74 drives the entire spray assembly to move to the left, so that the right push rod 64, the right turntable 65, the diversion pipe 66 and the nozzle 67 are pushed to the left, and the right turntable 65 moving to the left pushes the pressure ring 46 through the pressure piece 461, and the pressure ring 46 drives the spring part 47 to be compressed to the left, and the pressure ring 46 drives the insert plate 48 to move to the left along the dial plate 45, and the left side of the insert plate 48 enters the adjacent storage groove 422. At this time, the first slot 451 and the second slot 452 between the insert plate 48 and the dial plate 45 are exposed, and the nozzle 67 is respectively inserted into each socket 453.

[0065] Then, the external spray liquid delivery device delivers the spray liquid to the inner space of the right push rod 64 and the right turntable 65 through the pipe 641, and the spray liquid is diverted to each diversion pipe 66 and sprayed outwardly to the first slot 451 and the second slot 452 through each nozzle 67 of the diversion pipe 66, so that the spray liquid leaks outward from the first slot 451 and the second slot 452 to the inside of the cake-shaped filter residue between the left-rotating pressure plate 42 and the right-rotating pressure plate 62. At the same time, the two drive motors 32 start to run, and the output shafts of the two drive motors 32 respectively drive the two connected The two spur gears 33 rotate, and the two spur gears 33 respectively mesh with the two annular gear plates 31 connected thereto and drive them to rotate. The two annular gear plates 31 drive the left-handed pressure plate 42 and the right-handed pressure plate 62 to rotate synchronously through the convex strips 311, so that when the paddle plate 45 stirs the cake-shaped filter residue, part of the filter residue passes through the second slot 452 between the insert plate 48 and the paddle plate 45, so that the filter residue is fully stirred and each area of ​​the filter residue is evenly washed by the spray liquid. The washed spray liquid is discharged through the outlet end of the drain pipe 22 to the external waste liquid recovery equipment.

[0066] Afterwards, the external spray liquid delivery device and the two drive motors 32 stop working, and the washing process of the filter residue is completed.

[0067] The collection and treatment of filter residues of this copper extraction residual liquid recovery and treatment equipment:

[0068] After the washing process of the filter residue is completed, the telescopic end of the first electric push rod 53 resets the entire rotary dial assembly to the left, and the third push block 74 drives the entire spray assembly to reset to the right. Then the first cylinder 51 and the second cylinder 71 drive the left-rotating pressure plate 42 and the right-rotating pressure plate 62 to move toward each other again, so that the left-rotating pressure plate 42 and the right-rotating pressure plate 62 can flatten the cake-shaped filter residue that has completed the washing work to the inner right side of the filling assembly.

[0069] After that, the first cylinder 51 stops working, and the staff manually removes the fasteners connecting the hatch 23 and the sedimentation chamber 2. The telescopic end driven by the second cylinder 71 drives the right pressure rod 61 to move to the right, and the right pressure rod 61 drives the right-rotating pressure plate 62, the filling assembly and the hatch 23 to move to the right along the support block 72 until the filling assembly is completely removed from the sedimentation chamber 2.

[0070] Finally, the staff will remove the filling component. Since the cake-like filter residue is flattened to the inner right side of the filling component, the staff only needs to remove the frame bar 632 on the left side of the filling component that is not filled with cake-like filter residue, and can directly transfer the remaining filling component and the cake-like filter residue filled inside it to the temporary storage for storage, thus completing the filter residue collection and processing.

[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
