Description

Technical Field

[0001] This utility model relates to the field of coating wastewater treatment technology, specifically to an energy-saving recycling and treatment device for coating wastewater. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. Electroplating is widely used in various industries. After electroplating, the electroplating wastewater needs to be treated and discharged. In existing technologies, the plating wastewater treatment system mainly consists of an equalization tank, a neutralization reaction tank, a pH adjustment tank, and a flocculation tank. When the plating wastewater is in the neutralization reaction tank, alkali or other materials are added to the neutralization reaction tank to react and precipitate the metal ions in the plating wastewater, thus treating most of the metal ions in the plating wastewater. In existing technologies, the pipes used to transport the reaction solution are often set on the side wall of the neutralization reaction tank. However, this results in a long time required for the reaction solution to be fully mixed and reacted with the plating wastewater in the entire neutralization reaction tank, which is quite time-consuming.

[0006] As a further preferred embodiment of this technical solution, a rotating shaft is rotatably mounted on one side of the top of the movable frame via a bearing, and driven gears are fixedly mounted on both ends of the rotating shaft. Racks are fixedly mounted on both sides of the top of the neutralization reaction tank near the guide rail, and the driven gears are meshed with the racks. A first motor is fixedly mounted on one end of the movable frame, and a driving gear is fixedly mounted on the output end of the first motor, and the driving gear is meshed with the driven gear.

[0007] As a further preferred embodiment of this technical solution, a mounting bracket is fixedly installed at the top of one end of the movable frame, and a second motor is fixedly installed at the top of the mounting bracket. A belt drive assembly is installed between the output end of the second motor and the top of one of the stirring shafts near the second motor, as well as between the two adjacent stirring shafts at the same height.

[0008] As a further preferred embodiment of this technical solution, the movable frame has symmetrical sliding holes on one side, and a sliding rod is slidably installed inside the sliding hole.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, an energy-saving wastewater recycling and treatment device for plating includes a neutralization reaction tank 1. A movable frame 2 is slidably installed above the neutralization reaction tank 1. An inlet pipe 3 is fixedly installed on the top of the movable frame 2. The inlet pipe 3 is connected to a storage tank through a pipe and a pump body. A drain pipe 4 is installed at equal intervals in the middle of the inlet pipe 3. A stirring shaft 5 is rotatably installed at equal intervals in the middle of the movable frame 2 through bearings. A stirring blade 6 is fixedly installed at the bottom of the stirring shaft 5. By operating the pump body, the reaction liquid in the storage tank is discharged from the drain pipe 4 through the inlet pipe 3. Since the drain pipes 4 are equidistantly arranged in the middle of the moving frame 2 and are equidistantly positioned above the neutralization reaction tank 1, the reaction liquid can be evenly sprayed into the plating wastewater in the neutralization reaction tank 1, achieving uniform feeding of the reaction liquid into the plating wastewater. The moving frame 2 is controlled to move, and during the movement of the moving frame 2, several stirring shafts 5 can be driven to rotate synchronously, which in turn drives the stirring blades 6 to rotate. The stirring blades 6 can stir the plating wastewater in the neutralization reaction tank 1, improve the mixing effect of the reaction liquid on the plating wastewater, and improve the precipitation reaction effect of metal ions in the plating wastewater.

[0020] like Figures 1 to 3As shown, guide rails 7 are fixedly installed on both sides of the top of the neutralization reaction tank 1. The two ends of the moving frame 2 are slidably installed between the two guide rails 7. A rotating shaft 8 is rotatably installed on one side of the top of the moving frame 2 through a bearing. Driven gears 9 are fixedly installed on both ends of the rotating shaft 8. Racks 10 are fixedly installed on both sides of the top of the neutralization reaction tank 1 near the guide rails 7. The driven gears 9 are meshed with the racks 10. A first motor 11 is fixedly installed on one end of the moving frame 2. A driving gear 12 is fixedly installed on the output end of the first motor 11. The driving gear 12 is meshed with the driven gear 9.

[0021] The first motor 11 drives the drive gear 12 to rotate. The meshing of the drive gear 12 with the driven gear 9 will drive the driven gear 9 to rotate. At the same time, since the position of the rack 10 is fixed, the meshing of the driven gear 9 with the rack 10 can drive the moving frame 2 to move along the track of the guide rail 7.

[0022] like Figures 1 to 3 As shown, a mounting bracket 13 is fixedly installed on the top of one end of the movable frame 2, and a second motor 14 is fixedly installed on the top of the mounting bracket 13. A belt drive assembly 15 is installed between the output end of the second motor 14 and the top of one of the stirring shafts 5 near the second motor 14 and between the two adjacent stirring shafts 5 at the same height.

[0023] By controlling the operation of the second motor 14, and through several sets of belt drive assemblies 15, the transmission between the output end of the second motor 14 and the top of one of the stirring shafts 5, as well as the transmission between the two adjacent stirring shafts 5 at the same height, will drive several stirring shafts 5 to rotate synchronously.

[0024] like Figures 1 to 3 As shown, the movable frame 2 has symmetrical sliding holes 16 on one side, and a sliding rod 17 is slidably installed inside the sliding hole 16. A collection frame 18 is fixedly installed between the bottom ends of the two sliding rods 17. Collection grooves 19 are symmetrically opened on both sides of the collection frame 18. A third motor 20 is fixedly installed in the middle of the movable frame 2. A screw 21 is fixedly installed at the output end of the third motor 20. The screw 21 is threadedly connected to the middle of the collection frame 18.

[0025] By controlling the moving frame 2 to move along the track of the guide rail 7, the collection trough 19 on the collection frame 18 can push and collect the sediment at the bottom of the neutralization reaction tank 1. After the collection frame 18 is moved to one end of the neutralization reaction tank 1, the screw 21 is driven to rotate by the third motor 20. Through the threaded connection between the screw 21 and the middle of the collection frame 18 and the limiting of the sliding rod 17 by the sliding hole 16, the collection frame 18 will be driven to rise along the track of the sliding rod 17, which can lift the sediment in the collection frame 18. People can then collect the sediment in the collection trough 19, which can collect and process most of the sediment in the neutralization reaction tank 1, facilitating subsequent sediment processing.

[0026] like Figures 1 to 3 As shown, the collection frame 18 has an inclined angle 22 at the edge position corresponding to the collection groove 19.

[0027] When the bottom of the collection frame 18 is attached to the inner wall of the bottom of the reaction tank 1 and moved, the design of the tilt angle 22 makes it easy for the sediment to enter the collection tank 19.

[0028] like Figures 1 to 3 As shown, the bottom end of the drain pipe 4 is provided with side holes 23 arranged in a ring array with the central axis of the drain pipe 4 as the axis.

[0029] When the reaction solution is discharged from the drain pipe 4 of the inlet pipe 3, the reaction solution can also be discharged through the side hole 23, which increases the spray range of the reaction solution and further improves the uniform mixing of the reaction solution and the coating wastewater.

[0030] This utility model provides an energy-saving recycling and treatment device for coating wastewater, the specific working principle of which is as follows:

[0031] When the device is in use, the pump operates to discharge the reaction liquid in the storage tank through the inlet pipe 3 and the outlet pipe 4. Since the outlet pipes 4 are equidistantly positioned in the middle of the moving frame 2 and equidistantly positioned above the neutralization reaction tank 1, the reaction liquid can be evenly sprayed into the plating wastewater in the neutralization reaction tank 1, achieving uniform discharge of the reaction liquid into the plating wastewater. Simultaneously, the first motor 11 drives the drive gear 12 to rotate. The meshing of the drive gear 12 with the driven gear 9 drives the driven gear 9 to rotate. Meanwhile, since the position of the rack 10 is fixed, the meshing of the driven gear 9 with the driven gear 10... The meshing of the rack 10 can drive the moving frame 2 to move along the track of the guide rail 7. During the movement of the moving frame 2, the operation of the second motor 14 is controlled by several sets of belt drive components 15 to drive the output end of the second motor 14 and the top of one of the stirring shafts 5, as well as the transmission between the two adjacent stirring shafts 5 at the same height. This will drive several stirring shafts 5 to rotate synchronously, which in turn will drive the stirring blades 6 to rotate. The stirring blades 6 can stir the plating wastewater in the neutralization reaction tank 1, improve the mixing effect of the reaction liquid on the plating wastewater, and improve the precipitation reaction effect of metal ions in the plating wastewater.

[0032] Before the neutralization reaction, the bottom of the collection frame 18 is attached to the inner wall of the bottom of the neutralization reaction tank 1. After the reaction liquid reacts with the metal ions in the plating wastewater for a period of time, the moving frame 2 is controlled to move along the track of the guide rail 7. The collection tank 19 on the collection frame 18 can push and collect the sediment at the bottom of the neutralization reaction tank 1. After the collection frame 18 is moved to one end of the neutralization reaction tank 1, the screw 21 is driven to rotate by the third motor 20. The screw 21 is connected to the middle of the collection frame 18 by a thread and the sliding hole 16 limits the sliding rod 17, which will drive the collection frame 18 to rise along the track of the sliding rod 17. The sediment in the collection frame 18 can be lifted and the sediment in the collection tank 19 can be collected. Most of the sediment in the neutralization reaction tank 1 can be collected and processed, which is convenient for subsequent sediment processing.
