Description

Technical Field

[0001] The present invention relates to the field of electrolytic waste liquid treatment, and in particular to an electrolytic waste liquid treatment system for an electrolytic copper production process. Background Art

[0002] Electrolytic copper is a high-energy-consuming industry. The pollutants generated during the process mainly include anode mud and sulfuric acid produced by electrolysis. Anode mud is a by-product produced during the copper electrolysis process. It is composed of various components of the copper anode that are insoluble in the electrolyte during the electrolytic refining process.

[0003] Before treating the electrolytic waste liquid, the anode mud in the electrolytic waste liquid is generally precipitated in a sedimentation tank first, and then the electrolytic waste liquid is treated. This takes a lot of time to precipitate the anode mud. Currently, the anode mud is filtered, but the filter is easily clogged, and the filtration needs to be frequently stopped and the filter needs to be cleaned before filtration, which seriously affects the filtration efficiency of the electrolytic waste liquid and thus reduces the efficiency of the electrolytic waste liquid treatment. The precipitated or filtered anode mud still contains a large amount of water, which is inconvenient to dehydrate the anode mud containing water, and will affect the subsequent treatment of the anode mud.

The feed pipe 63 is connected to cavity one. An overflow pipe 64 is installed on one side of the reaction cylinder 61. The overflow pipe 64 is connected to cavity two. A drain pipe 65 is installed at the lower part of the reaction cylinder 61. The drain pipe 65 is connected to the lower part of the reaction cylinder 61.

[0035] The filtering mechanism includes an annular guide rail 71, an electric slider 72, an annular plate 73 and a filter screen plate 74. Two annular guide rails 71 are installed on both sides of the outer shell 2. The two annular guide rails 71 are symmetrically arranged. Six electric sliders 72 are evenly spaced and installed on the side where the two annular guide rails 71 are close to each other. The electric sliders 72 will rotate along the annular guide rails 71. An annular plate 73 is installed between the six electric sliders 72 on both sides. Six filter screen plates 74 are evenly spaced and installed on the annular plate 73. The annular plate 73 and the six filter screen plates 74 are located between the outer shell 2 and the reaction cylinder 61.

[0036] The cleaning mechanism includes a horizontal shaft 81, a torsion spring 82, an arc-shaped pressure plate 83 and a scraper inclined plate 84. A discharge port 841 is opened on one side of the upper part of the shell 2. A horizontal shaft 81 is rotatably installed on one side of the shell 2 near the discharge port 841. Both ends of the horizontal shaft 81 pass through the two sides of the shell 2 respectively. A torsion spring 82 is respectively installed between the two ends of the horizontal shaft 81 and the outer sides of the shell 2. An arc-shaped pressure plate 83 is installed in the middle of the horizontal shaft 81. The arc-shaped pressure plate 83 is located between the shell 2 and one of the filter screens 74. One side of the arc-shaped pressure plate 83 is in contact with the filter screen 74. A scraper inclined plate 84 is installed at the lower part of the discharge port 841. The other end of the scraper inclined plate 84 is in close contact with one of the filter screens 74.

[0037] An acute angle is formed between the arc-shaped pressing plate 83 and the filter screen plate 74 . A gap is left between the side of the arc-shaped pressing plate 83 close to the horizontal axis 81 and the filter screen plate 74 , and the side of the arc-shaped pressing plate 83 away from the horizontal axis 81 is in contact with the filter screen plate 74 .

[0038] The operator first starts the electric sliders 72 on both sides to slide along the annular guide rail 71, and the electric sliders 72 on both sides drive the annular plate 73 and the six filter screens 74 to rotate, and then connect the external input pipe to the porous tube 3, and the electrolytic waste liquid is discharged from the inlet 21 to the filter screen 74 through the porous tube 3. The anode mud in the electrolytic waste liquid can be filtered through the filter screen 74, and the filtered electrolytic waste liquid is discharged into the reaction cylinder 61. The operator continuously supplies alkaline neutralizing liquid into the reaction cylinder 61 through the feed pipe 63, and then the operator opens the overflow pipe 64. The filtered electrolytic waste liquid and alkaline neutralizing liquid are discharged into the cavity 1 for neutralization reaction, and the electrolytic waste liquid at the bottom that has been neutralized passes through the through groove 621 at the bottom. The electrolytic waste liquid is discharged into the second chamber, and the electrolytic waste liquid after the neutralization reaction is discharged through the overflow pipe 64; the annular plate 73 drives the anode mud filtered out of the filter screen plate 74 to rotate. After one of the filter screen plates 74 moves to the discharge port 841, the anode mud filtered out of the filter screen plate 74 contacts the arc pressure plate 83. Under the action of the torsion spring 82, the arc pressure plate 83 can swing along the horizontal axis 81, thereby providing a suitable downward pressure on the anode mud, thereby squeezing out the water in the anode mud on the filter screen plate 74. After the anode mud with no water squeezed out moves to contact the scraper inclined plate 84, the scraper inclined plate 84 scrapes the anode mud with no water squeezed out and is discharged from the discharge port 841; the electrolytic liquid is removed by the filter screen plate 74 The anode mud in the waste liquid is quickly filtered out, thereby reducing the anode mud in the electro-liquid waste liquid, allowing the electro-liquid waste liquid to be more fully in contact with the alkaline neutralizing solution, thereby improving the efficiency of the electro-liquid waste liquid neutralization. The anode mud contacts the arc pressure plate 83, and the arc pressure plate 83 can provide a suitable downward pressure on the anode mud, thereby squeezing out the water in the anode mud on the filter screen plate 74. The squeezed water is collected and poured into the reaction cylinder 61 for treatment, thereby reducing the water content in the anode mud and facilitating the operator to perform subsequent treatment of the anode mud. After being squeezed out, the water in the anode mud passes through the filter screen plate 74 at the discharge port 841 and flows downward along the outer wall of the reaction cylinder 61. The water squeezed out of the anode mud passes through the filter screen plate 74 at the discharge port 841. The filter screen plate 74 near the collection box 4 is discharged into the collection box 4. After an appropriate amount of electro-liquid waste liquid is collected in the collection box 4, the operator opens the drain pipe 5, and the electro-liquid waste liquid in the collection box 4 is discharged through the drain pipe 5. The operator collects the discharged electro-liquid waste liquid and pours it into the reaction cylinder 61 for treatment. After the electro-liquid waste liquid in the collection box 4 is discharged, the operator closes the drain pipe 5; after the electro-liquid waste liquid is treated, the operator first stops supplying alkaline neutralizing liquid, and then closes the electric slider 72, and finally closes the overflow pipe 64 and opens the drain pipe 65, and discharges all neutralized electro-liquid waste liquid in the reaction cylinder 61 through the drain pipe 65. After all neutralized electro-liquid waste liquid is discharged, the operator closes the drain pipe 65.

The steel wire on the wire brush holder 95 can intermittently brush the bottom of the filter screen plate 74, thereby brushing the anode mud blocked on the filter screen plate 74, thereby preventing the anode mud from accumulating on the filter screen plate 74, thereby improving the water permeability of the filter screen plate 74, and then accelerating the filtration efficiency of the electro-hydraulic waste liquid, thereby further improving the treatment efficiency of the electro-hydraulic waste liquid. After the electro-hydraulic waste liquid is treated, the operator turns off the servo motor 91.

[0042] Example 3: Based on Example 2, Figures 9-12As shown, a mixing mechanism is also included. The mixing mechanism is arranged on the central axis 92 and the reaction cylinder 61.
