Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a sewage treatment device for copper smelting production. Background Technique

[0002] During the process of copper smelting, a large amount of sewage will be generated. Copper smelting wastewater is the wastewater generated during the wet smelting process of copper. This kind of wastewater contains high-concentration metal ions, especially copper ions, and is not allowed to be directly discharged. It should be recycled as much as possible. For the wastewater that must be discharged, it needs to undergo coagulation precipitation and flotation treatment to meet the discharge standard before it can be discharged.

[0003] During the treatment of existing copper smelting wastewater, sedimentation tanks are usually used to sediment the sewage. However, after long-term use of the sedimentation tank, a large amount of sludge accumulates at the bottom of the sedimentation tank. If it is not cleaned in time, it will affect the normal use of the sedimentation tank. Most of the existing sedimentation tanks are cleaned manually, and the cleaning process is relatively slow. Moreover, during the cleaning process, the treatment of wastewater needs to be suspended, which affects the progress of sewage treatment. It is impossible to clean the sedimentation tank while treating the wastewater to ensure the normal progress of the wastewater treatment work. Therefore, a sewage treatment device for copper smelting production is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sewage treatment device for copper smelting production. By using two first control valves on the U-shaped shunt pipe, one of the first control valves can be closed to allow sewage to enter another sedimentation tank, which is convenient for cleaning the sedimentation tank that has stopped working. During the cleaning process, the first connecting pipe can be used in combination to connect the extraction hose, and with the action of the sludge pump, the bottom of the sedimentation tank can be cleaned. During the cleaning process, the moving frame slides on the fixed frame for horizontal movement, and with the action of the first driving motor, the first screw rod and the connecting block are screwed together to move the sludge pump horizontally in the longitudinal direction to clean the bottom of the sedimentation tank comprehensively.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A sewage treatment device for copper smelting production, including two sedimentation tanks. A U-shaped shunt pipe is fixedly connected to one side of the two sedimentation tanks. Two symmetrically arranged first control valves are fixedly connected to the U-shaped shunt pipe.

[0027] As Figures 1 to 5As shown in the figure, the sewage treatment device provided by the embodiment of the utility model for copper smelting production includes two sedimentation tanks 1. A U-shaped shunt pipe 11 is fixedly connected to one side of the two sedimentation tanks 1. Two symmetrically arranged first control valves 12 are fixedly connected to the U-shaped shunt pipe 11. By using the U-shaped shunt pipe 11, sewage can be conveyed into the two sedimentation tanks 1. A fixed frame 13 is fixedly connected to the outer wall of the sedimentation tank 1.

A sludge pump 18 is fixedly connected to the upper end surface of the moving plate 17. A first connecting pipe 19 is fixedly connected to the lower end surface of the sludge pump 18. By using the first connecting pipe 19, it can be connected to an extraction hose. In cooperation with the use of the sludge pump 18, the bottom of the sedimentation tank 1 can be cleaned. A connecting block 20 is fixedly connected to the upper end surface of the positioning frame 16. A stabilizing block 21 is fixedly connected to the upper end surface of the moving frame 14. A first forward and reverse motor 22 is fixedly connected to the upper end surface of the stabilizing block 21. The output end of the first forward and reverse motor 22 is connected to a first screw rod 23. The first screw rod 23 is screwed to the connecting block 20. When the first forward and reverse motor 22 operates, the first screw rod 23 is screwed to the connecting block 20. The positioning frame 16 and the moving plate 17 are driven to move through the connecting block 20, so as to realize the longitudinal horizontal movement of the sludge pump 18. The moving frame 14 moves horizontally in the transverse direction, which is convenient for comprehensively cleaning the bottom of the sedimentation tank 1. Two symmetrically arranged positioning plates 31 are fixedly connected to the upper end surface of the fixed frame 13. A second forward and reverse motor 32 is fixedly connected to the upper end surface of the positioning plate 31. The output end of the second forward and reverse motor 32 is connected to a second screw rod 33. The second screw rod 33 is screwed to the moving frame 14. The two ends of the second screw rod 33 are respectively rotatably connected to a retaining block 34. The retaining block 34 is fixedly connected to the fixed frame 13. When the two second forward and reverse motors 32 rotate in opposite directions at the same time, the two second screw rods 33 can be screwed to the moving frame 14 to control the moving frame 14 to move horizontally in the transverse direction. Two symmetrically arranged limiting grooves 41 are formed on the upper end surface of the fixed frame 13. A limiting block 42 is slidably connected in the limiting groove 41. The limiting block 42 is fixedly connected to the moving frame 14. By using the two limiting grooves 41 and the two limiting blocks 42 on a single fixed frame 13, the moving frame 14 can be limited to ensure the stability of the movement of the moving frame 14. A drain pipe 51 is fixedly connected to the side of the sedimentation tank 1 away from the U-shaped shunt pipe 11. A second control valve 52 is fixedly connected to the drain pipe 51.

A second connecting pipe 61 is fixedly connected to one side of the sludge pump 18. The second connecting pipe 61 on a single sludge pump 18 can be connected to a collection pipe to collect and clean the extracted sludge. A water inlet pipe 71 is fixedly connected to the U-shaped shunt pipe 11.

When it is necessary to clean the sedimentation tank 1, first close one of the first control valves 12, so that the sewage passes through the other sedimentation tank 1 for treatment, and cooperate with the drain pipe 51 on the sedimentation tank 1 that is working to drain the sewage in the sedimentation tank 1 that has stopped working. Connect the extraction hose to the first connecting pipe 19 and the collection pipe to the second connecting pipe 61. Under the action of the sludge pump 18, clean the sludge at the bottom of the sedimentation tank 1. During the cleaning process, the first forward and reverse motor 22 works to make the first screw rod 23 and the connecting block 20 engage in a screw connection, controlling the sludge pump 18 on the upper end surface of the moving plate 17 to achieve the longitudinal horizontal movement of the sludge pump 18. The simultaneous reverse rotation of the two second forward and reverse motors 32 can make the two second screw rods 33 rotate to move the moving frame 14, so that the moving frame 14 drives the sludge pump 18 to move horizontally in the transverse direction to clean the bottom of the sedimentation tank 1 comprehensively. After the cleaning is completed, open the closed first control valve 12 and close the other first control valve 12, and repeat the above operations to clean the other sedimentation tank 1, so as to realize the usage process of the entire sewage treatment device.
