Description

Technical Field

[0001] The present invention relates to the field of electroplating wastewater treatment, and specifically to an electroplating wastewater treatment device and a treatment system. Background Art

[0002] The electroplating process is a method of coating a conductive body with a layer of metal by using the principle of electrolysis; electroplating refers to a surface processing method in which, in a salt solution containing the pre-plated metal, the substrate metal to be plated is used as the cathode, and through electrolysis, the cations of the pre-plated metal in the plating solution are deposited on the surface of the substrate metal to form a coating. The properties of the coating are different from those of the substrate metal and have new characteristics. According to the function of the coating, it is divided into protective coatings, decorative coatings and other functional coatings. A large amount of electroplating wastewater is generated during the electroplating process. The quality of electroplating wastewater is complex and its composition is not easy to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver and cyanides, etc. Some of them are highly toxic substances that can cause cancer, birth defects and mutations. In order to prevent pollution, electroplating wastewater needs to be treated before it can be discharged.

Then, the driving motor 2 can be started to drive the reciprocating screw 9 and the support shaft 4 to rotate. Thus, the support shaft 4 can cooperate with the bevel gear 5 and the second bevel gear 14 to drive the support rod 6 to rotate, so that the stirring plate 7 can stir the electroplating wastewater to mix the electroplating wastewater with the treatment liquid. Then, through the arrangement of the reciprocating screw 9, the auxiliary plate 11 can stir the corners of the treatment tank body 1 up and down, so that the electroplating wastewater and the medicament at the corners can be evenly mixed, which is convenient for the medicament to be mixed with the electroplating wastewater for treatment.

[0034] Embodiment 2: On the basis of Embodiment 1, a reciprocating screw 9 is provided to facilitate the full mixing of the medicament and the electroplating wastewater.

[0035] During use, first, the driving motor 2 can be directly started, so that one group of reciprocating screws 9 can be driven to rotate by the meshing transmission of the auxiliary gear 17 and the gear 15. By using the belt drive of the traction belt 18 and the traction wheel 12, the other group of reciprocating screws 9 can be driven to rotate, so that the lifting plate 10 can reciprocate on the reciprocating screw 9, and then the auxiliary plate 11 can move up and down along the square corner of the treatment tank body 1, thus facilitating the full mixing of the medicament and the electroplating wastewater at the square corner of the treatment tank body 1.

[0036] In order to improve the mixing of the electroplating wastewater and the medicament, a stirring plate 7 is provided. The bottom plate 3 is in a square plate structure.

The guide plate 33 cooperates with the traction rod 32 to avoid the problem that the material discharging bucket 34 also rotates when the moving screw 30 rotates. Then, the displacement of the slider 35 can drive the material discharging bucket 34 to displace on the surface of the treatment tank body 1, so that the agent in the material discharging bucket 34 can flow uniformly on the surface of the electroplating wastewater, facilitating subsequent stirring and mixing.

[0040] In order to facilitate the treatment of the sludge generated inside the treatment tank body 1 due to long-term use, a push plate 38 is provided.

[0041] During use, the moving screw 30 can be rotated, so that the pull plate 37 can displace along the moving screw 30, thereby driving the push plate 38 to displace at the bottom of the treatment tank body 1. The sludge at the bottom of the treatment tank body 1 can be pushed to the material discharging port 13 by the push plate 38. Then, the electric push rod 24 is started to lower the sealing plate 27 to lose the seal of the material discharging port 13, so that the sludge can be conveniently discharged from the material discharging port 13. When the sludge does not need to be cleaned, the displacement of the push plate 38 at the bottom of the treatment tank body 1 can be used to generate fluctuations at the bottom of the electroplating wastewater, facilitating the precipitation of the agent inside the treatment tank body 1.
