Description

Technical Field

[0001] The utility model relates to the technical field of flushing the surface of the copper removal and impurity removal tank in the copper electrolysis purification liquid system, in particular to a flushing system for the surface of the copper removal and impurity removal tank in copper electrolysis purification liquid. Background Technique

[0002] In the PC copper electrolysis technology, thick copper plates containing 99%-99.5% copper are used as anodes, and stainless steel plates are used as cathodes. Electrolysis is used to prepare high-purity cathode copper, which is then applied in industries such as machinery, construction, and national defense. However, during the electrolysis process, as the anode copper continuously dissolves, metals with negative potentials enter the solution, mainly including impurities such as arsenic, antimony, and bismuth, resulting in the continuous enrichment of the impurity content in the electrolyte beyond a certain control range, causing situations such as particles in the cathode copper and affecting the quality of the cathode copper. Therefore, some of the electrolyte used in the electrolytic refining process is purified. The electrolyte entering the purification liquid system successively undergoes a copper removal process - a concentration process - a water-cooled crystallization process - an impurity removal process - a freezing crystallization process to achieve the purification of the electrolyte.

[0003] After the electrolyte undergoes the copper removal, concentration, and water-cooling processes, the electrolyte with a copper content of about 28 g / L is transported to an impurity removal tank made of concrete casting and FRP anti-corrosion for the removal of copper and impurities. Every 8 impurity removal tanks form a group, and the purification is carried out in an up-in and down-out manner for 7 days (one cycle). However, within this one cycle, as the copper removal and impurity removal time prolongs, a large amount of copper sulfate crystals will be generated at the contact points between the anode and cathode plates and the conductive copper busbars. If not handled in time or not handled thoroughly, a large amount of copper will precipitate on the insulating plates between the conductive rods and conductive plates of the anode and cathode, forming a short-circuit problem. If the time is too long, a fire problem will occur, posing a serious process safety hazard, which will affect the production process indicators to a lesser extent and may even lead to a fire and production suspension in severe cases. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model designs a flushing system for the surface of the copper removal and impurity removal tank in copper electrolysis purification liquid.

The output ports of the "L"-shaped pipes are respectively connected to rotating spray heads. One side of the outer wall of the FRP cover is connected to a water inlet pipe, and the water inlet pipe communicates with each water delivery pipe.

[0007] Preferably, the water delivery pipe is arranged below the inner top of the fiberglass cover and is disposed along the length direction of the conductive copper busbar on the surface of the copper electrolysis purified liquid copper removal and impurity removal tank, corresponding to the contact points between single tanks of the copper removal and impurity removal tank and the busbars at both ends.

[0008] Preferably, three "L"-shaped pipes perpendicular to the water delivery pipe are provided on the pipe body of the water delivery pipe, and inclined water outlet holes are provided on the pipe body at the water outlet ends of the "L"-shaped pipes.

[0009] Preferably, the water inlet pipe is fixed to the outer wall of the fiberglass cover along the vertical direction of the conductive copper busbar.

[0012] Preferably, spray nozzles inclined at 45° are provided at both ends of the rotary spray head.

[0013] Preferably, a baffle is provided on the inner wall of the rotary spray head.

[0014] The beneficial effects of the present utility model are as follows: The present utility model can precisely flush each contact point of copper sulfate crystals between the anode and cathode plates and the conductive copper busbar, effectively preventing the problem of short circuit and fire of the plates in the copper electrolysis purified liquid copper removal and impurity removal tank, thereby reducing safety risks and preventing fires.

[0021] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0022] Embodiment: As Figures 1 - 5 shown, a copper electrolysis purification liquid copper and impurity removal tank surface flushing system includes a fiberglass cover 1, a water delivery pipe 2, a water inlet pipe 3, an "L"-shaped pipe 4, a rotary nozzle 5, a quick-connect joint 6, and a three-way ball valve 7. The fiberglass cover 1 is placed above the copper and impurity removal tank provided with conductive copper busbars, and its length direction is perpendicular to the direction of the conductive copper busbars; 9 rows of water delivery pipes 2 are provided at the inner top of the fiberglass cover, arranged along the direction of the conductive copper busbars; 3 groups of "L"-shaped pipes 4 perpendicular to the copper and impurity removal tank are provided on the body of the water delivery pipe 2; 3 water outlet holes 9 are provided at the "one" end of the "L"-shaped pipe 4, and a rotary nozzle 5 is connected; a spray port 8 is provided on the rotary nozzle; and a baffle 10 is provided on the inner wall of the rotary nozzle; the water delivery pipe 2 and the water inlet pipe 3 are connected by a three-way ball valve 7; the water inlet pipe 3 is fixedly connected to the outside of the fiberglass cover 1, one end is blocked by a blind plate, and the other end is connected to the main water inlet pipe through a quick-connect joint 6.

[0023] In the operation of flushing the surface of the copper and impurity removal tank in this embodiment, the quick-connect joint 6 is connected to the main pipe, the valve on the main pipe is opened, and the condensed water enters the water delivery pipe 2 through the water inlet pipe 3. In order to ensure that each rotary nozzle 5 can accurately flush the crystals at the contact point, the three-way ball valves 7 of the water delivery pipes 2 are opened in sequence, and the condensed water enters the "L"-shaped pipe through the water delivery pipe 2 and is flushed through the rotary nozzle 5. During the flushing process, the rotary nozzle 5 rotates by means of the impact force of the water outlet holes 9 of the water delivery pipe 2, and the condensed water performs a rotary flushing operation through the spray port 8 of the rotary nozzle 5. When performing the loading and unloading operation of the copper and impurity removal tank, the quick-connect joint 6 is opened, and then the fiberglass cover 1 is hoisted away by a crane to perform the loading and unloading operation. During the flushing operation, the operation is safe and convenient, there is no problem of scalding by condensed water and incomplete flushing of the crystals at the contact point, and the key problem of difficult flushing due to limited space angle in the prior art is effectively solved.

[0024] In this embodiment, as Figure 1 shown, 9 rows of water delivery pipes 2 are provided at the inner top of the fiberglass cover 1 above the copper and impurity removal tank. The body of the water delivery pipe 2 is provided with an "L"-shaped pipe 4 perpendicular to the copper and impurity removal tank. The "one" of the "L"-shaped pipe 4 is connected with a rotary nozzle 5, which is convenient for rotating and flushing with the impact force of the water outlet holes 6 of the water delivery pipe 2 during the flushing operation; the water delivery pipe 2 and the water inlet pipe 3 are connected by a three-way ball valve 7 to control the water inlet of each row of water delivery pipes 2 in sequence.

[0025] As Figure 2As shown, one end of the water inlet pipe 3 is blocked by a flange and a blind plate, and the other end is connected to the main water pipe through a quick-connect joint 6. When carrying out the manual operation of loading and unloading the groove, first open the quick-connect joint 6, and then hoist the fiberglass cover 1, so as not to affect the loading and unloading of the anode and cathode plates into the groove.

[0026] As Figures 3 - 5 shown, it is a detailed view of the internal structure of the water outlet pipe of the "L"-shaped pipe 4 and the rotating nozzle 5. Its main operation is that after the condensed water enters the "L"-shaped pipe 4, the baffle 10 on the inner wall of the rotating nozzle 5 is impacted by the water outlet hole 9 at the "one" position of the "L"-shaped pipe 4, so as to drive the rotation of the rotating nozzle 5, so that the condensed water in the rotating nozzle 5 washes the contact points between the anode and cathode plates and the conductive copper busbars through the spray ports 8.

[0027] The above-described embodiments are only a preferred solution of the present invention, and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
