Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste treatment, and particularly to a device for disposing of chemical nickel waste liquid. Background Art

[0002] Chemical nickel has high hardness, strong corrosion resistance; low porosity of the coating, no pores in 15μm; good wear resistance, superior to electroplated chromium; good solderability, can be wetted by solder, and good electromagnetic shielding performance, and can be used for electronic components and computer hard disks. Chemical nickel plating waste liquid is mainly composed of metal salts, reducing agents, pH buffers, stabilizers or complexing agents, etc. Among them, the most used nickel salt is sulfate, and the main reducing agents are hypophosphite, borohydride, etc. In the PCB and electroplating industries, in order to increase the solderability, coating adhesion and appearance color of the plated parts, surface treatment processes are often adopted, generally using inert precious metals such as gold, silver, palladium, etc., which have strong oxidation resistance and good solderability, but the prices of these metals are expensive, the coatings are generally thin, and a layer of nickel often needs to be plated between the precious metal and the substrate, which can not only reduce costs, but also improve the compatibility between the precious metal and the base material. The chemical nickel plating process is mainly used. At present, the most commonly used chemical nickel plating adopts the hypophosphite reduction method, but the service life of this solution is short, the bath liquid needs to be replaced frequently, generating a large amount of nickel-containing and phosphorus-containing waste liquid. As a heavy metal waste water, nickel-containing waste water has strong toxicity, and the precipitate of its insoluble matter with other precipitants is large, and it is difficult to remove metal nickel ions by chemical precipitation to reach below the discharge standard. The current treatment status still has huge environmental hazards.

[0003] At present, the ion exchange method is used to treat chemical nickel plating waste liquid. The advantages are high automation degree and high quality of recycled nickel. However, after the ion exchange resin is used up, it is not convenient to take it out of the treatment tank for treatment. At the same time, there will still be a lot of impurities remaining in the treatment tank after the reaction, and it is also inconvenient to clean them out of the treatment tank. For incompletely treated chemical nickel waste liquid, an oxidant is also used to continue the purification reaction. However, when the oxidant is put into the chemical nickel waste liquid, the reaction time between it and the chemical nickel waste liquid is long, and the reaction is uneven, affecting the purification effect.

[0025] Please refer to Figure 1-9 , the present invention provides a technical solution: a device for disposing chemical nickel waste liquid, including a box body 1 and a mesh frame 2. Above the surface of the box body 1, a ring plate 3 is fixedly connected, and on both sides of the top of the two ring plates 3, a protection box 4 is fixedly connected. At the top of the inner wall of the protection box 4, a first motor 5 is fixedly connected, and the output end of the first motor 5 is fixedly connected with a threaded rod 6. The surface of the threaded rod 6 is threadedly connected with a slide block 7, and between the opposite sides of the two slide blocks 7, a cover plate 8 is fixedly connected. On the top of the cover plate 8, a second motor 9 is fixedly connected, and the output end of the second motor 9 is fixedly connected with a vertical rod 10. On both sides of the surface of the vertical rod 10, a support frame 11 is fixedly connected, and inside the support frame 11, a placing frame 12 is arranged. At the bottom end of the vertical rod 10, a connecting rod 13 is fixedly connected, and on both sides of the top of the surface of the connecting rod 13, a collection box 14 is arranged. At the top of the collection box 14, a fixed rod 15 is fixedly connected, and at the top end of the fixed rod 15, a fixed plate 16 is fixedly connected. The fixed plate 16 is slidably connected to the bottom of the support frame 11, and between the two sides of the inner wall of the box body 1, a partition board 17 is fixedly connected. Between the top of the partition board 17 and the bottom of the mesh frame 2, a first bearing 18 is rotatably connected, and at the bottom of the partition board 17, a stirring rod 20 is rotatably connected through a second bearing 19. The bottom end of the connecting rod 13 penetrates through the first bearing 18 and the second bearing 19 and extends to the inside of the second bearing 19.

[0027] Specifically, the ion exchange resin is placed in the placement frame 12 and enters the mesh frame 2. After reacting with the electroless nickel waste liquid, the placement frame 12 can be directly taken out to remove the ion exchange resin. This operation is relatively convenient and also achieves the purpose of the reaction.

[0028] In the present invention, connecting plates 23 are fixedly connected to opposite sides of the slider 7, and the other side of the connecting plate 23 is fixedly connected to one side of the cover plate 8. A sliding groove 24 adapted to the connecting plate 23 is provided on one side of the protection box 4.

[0029] In the present invention, limiting frames 25 are fixedly connected to both sides of the surface of the vertical rod 10 and above the support frame 11. A sealing plate 26 is slidably connected to the top inside the placement frame 12, and a slot 27 adapted to the sealing plate 26 is provided at the top of one side of the placement frame 12. The sealing plate 26 is provided to prevent the internal ion exchange resin from coming out of the placement frame 12.

[0030] Specifically, when the placement frame 12 enters the inside of the mesh frame 2, it rotates to fully contact and react with the electroless nickel waste liquid. At the same time, the mesh frame 2 and the collection frame 14 also rotate together with the placement frame 12. The rotation of the mesh frame 2 facilitates the filtration of the reacted electroless nickel waste liquid, leaving impurities inside the mesh frame 2. The use of the collection frame 14 can collect the impurities. When the placement frame 12 rises and moves out of the box body 1, the collection frame 14 will also move out of the box body 1 together, facilitating manual cleaning.

[0031] In the present invention, a movable groove 28 adapted to the fixed plate 16 is provided at the bottom of the support frame 11, and a limiting plate 29 is provided between the tops of the two collection frames 14. Limiting rods 30 are fixedly connected to both sides of the bottom of the limiting plate 29. The bottom ends of the limiting rods 30 penetrate through the collection frame 14 and extend into the inside of the collection frame 14. Limiting holes 31 adapted to the limiting rods 30 are provided at the top of the collection frame 14.

[0032] In the present invention, a cross plate 32 is fixedly connected to one side of the support frame 11, and a card slot 33 adapted to the cross plate 32 is provided on the inner wall of the mesh frame 2.

[0034] Specifically, the rotation mixing method is adopted to accelerate the reaction rate with the oxidant.

[0035] In the present invention, a liquid inlet pipe 36 is communicated above the top of the surface of the box body 1 and above the wire frame 2. A feed pipe 37 is communicated below one side of the box body 1 and below the partition 17. A discharge pipe 38 is communicated below the feed pipe 37 on one side of the box body 1. A discharge pipe 39 is communicated at the bottom of the other side of the box body 1, and the height of the discharge pipe 39 is higher than that of the discharge pipe 38.

[0036] Specifically, the height of the discharge pipe 39 is higher than that of the discharge pipe 38 to discharge the purified liquid first, and the discharge pipe 38 is for discharging the precipitate.

[0037] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] During use, move the two collection frames 14 towards each other so that the fixing plates 16 on the collection frames 14 slide into the movable slots 28 at the bottom of the support frame 11. Then insert the limiting rods 30 at the bottom of the limiting plate 29 into the limiting holes 31 on the collection frames 14 to position the two collection frames 14. Pour ion exchange resin into the interior of the placement frame 12. Then insert the sealing plate 26 into the interior of the placement frame 12 from the slot 27. Then insert the placement frame 12 into the limiting frame 25 until the bottom of the placement frame 12 contacts the top of the support frame 11. Start the first motor 5 through an external switch. The first motor 5 drives the threaded rod 6 to rotate. The threaded rod 6 drives the slider 7 to move downward, so that the connecting plate 23 drives the cover plate 8 to move downward. During the downward movement, the cross plate 32 on the support frame 11 will be stuck into the card slot 33 of the wire frame 2. At the same time, the connecting rod 13 at the bottom of the vertical rod 10 will be stuck into the second bearing 19, and the block 21 will be stuck into the clamping plate 22, causing the connecting rod 13 to rotate and the second bearing 19 to rotate together;

[0039] When the collection frame 14 moves to the bottom inside the wire frame 2, the first motor 5 stops rotating. Then inject the electroless nickel waste liquid through the liquid inlet pipe 36. Then start the second motor 9 through an external switch. The second motor 9 drives the vertical rod 10 to rotate. The vertical rod 10 drives the placement frame 12 to rotate, so that the ion exchange resin reacts fully with the electroless nickel waste liquid. Open the one-way valve inside the vertical pipe 34. The reacted liquid flows down from the vertical pipe 34. The residues in the liquid during the reaction fall into the interior of the collection frame 14. Pour the oxidant through the liquid inlet pipe 36. The stirring rod 20 drives the stirring blade 35 to rotate to react the oxidant with the liquid. After the reaction, precipitation occurs. The purified liquid is discharged from the discharge pipe 39, and the precipitate is discharged from the discharge pipe 38. Start the first motor 5 again. Driven by the first motor 5, lift the placement frame 12 and the collection frame 14 out of the box body 1 for easy manual cleaning.
