Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment, in particular to electroplating wastewater sludge reduction treatment equipment. Background Art

[0002] Electroplating wastewater refers to the wastewater generated in the electroplating process, which may contain various metal ions, acids, alkalis and other chemical substances. Electroplating is a process of depositing a layer of metal or alloy on the surface of an object to improve the surface performance, corrosion resistance or aesthetics of the object. In this process, some wastewater will be generated. These wastewaters may have a negative impact on the environment. Therefore, it is very necessary to treat this electroplating wastewater.

[0003] A Chinese patent with publication number CN211664859U discloses a wastewater treatment device for fully automatic electroplating equipment, including a machine base, a flocculation box and a filter box; the utility model has a reasonable structural design. When working, wastewater is injected through the water injection port, and additives are added through the additive feeding pipe to treat various heavy metals in the water. The motor finally drives the first stirring blade to rotate through the driving wheel, so that the additives are mixed more fully and the treatment efficiency is improved. The sewage is discharged into the flocculation box, and flocculants and acid-base neutralizing agents are added. The second stirring blade is used for stirring and mixing, which reduces the use of the motor and the production cost. The sewage is discharged into the filter box and is filtered in layers through a coarse-pore filter layer, a fine-pore filter layer and an activated carbon adsorption layer, so that flocculated pollutants and odors are effectively removed, the clean water is recycled, energy saving and environmental protection are achieved, the problem that traditional flocculation sedimentation takes a long time is solved, and the treatment efficiency is greatly improved. In addition, the device occupies a small area and is easy and fast to move and place.

[0028] Working principle: since the above patent provides a wastewater treatment device for fully automatic electroplating equipment, although it can perform layered filtration and water purification, there is a lot of sludge in the electroplating wastewater. Simply filtering through a fine-pore filter layer and an activated carbon adsorption layer may cause blockage at the filter holes, making it necessary to continuously dredge the filter holes during filtration. At the same time, the filtration is not thorough enough, which affects the efficiency of sludge reduction treatment of electroplating wastewater. When working, the base 1 supports the box body 2, and the sludge reduction treatment of the electroplating wastewater is performed inside the box body 2. During treatment, the elastic filter screen plate 13 is first used for filtration, and during filtration, the electroplating wastewater is discharged into the box body 2, and then the active pulley 4 rotates to drive the stirring shaft 6 to rotate, thereby driving the stirring impeller 7 to rotate.

In addition, a middle isolation plate 14 and a lower isolation plate 15 are set to support the snail adjustment layer 18 and the PH adjustment layer 19 respectively, wherein the snail adjustment layer 18 uses snails to purify water quality, and the PH adjustment layer 19 adjusts the PH of the purified water quality. At the same time, the water pipe 16 is connected to the bottom of the middle isolation plate 14 and the lower isolation plate 15, and the drainage is controlled by the electric valve 17, thereby realizing the role of stratified water treatment. The protective cover 20 is The driving pulley 4 and the driven pulley 5 are protected and the motor barrel 21 is supported at the same time. The motor 22 is installed inside the motor barrel 21.

In addition, the water inlet pipe 24 cooperates with the connecting flange 25 to connect the external pipeline, so that the external electroplating wastewater is discharged into the box body 2.
