Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater recycling technology, and in particular to an electroplating wastewater recycling and treatment device. Background Technology

[0002] Electroplating wastewater has a complex composition, often containing various heavy metal ions, cyanides, organic matter, and complexing agents, among other toxic and harmful substances. Direct discharge without proper treatment will cause serious harm to the ecological environment and human health. Currently, physicochemical methods are widely used for electroplating wastewater treatment, with the "coagulation-flocculation" process being the core step. This process involves adding chemicals to destabilize and aggregate fine suspended solids and colloidal particles that are difficult to settle, forming larger flocs that are easier to separate. This is a crucial step in achieving solid-liquid separation and pollutant removal. However, existing flocculation processes, especially mechanical agitation flocculation, largely rely on the fluid dynamics conditions formed during agitation. In the initial stage of flocculation, sufficient agitation intensity is required to ensure thorough mixing of the chemicals and wastewater; however, as micro-flocs form, excessive shear force can easily break and disperse the fragile flocs, leading to flocculation failure and the formation of small, loose flocs with extremely poor settling properties. This severely affects subsequent sedimentation and separation effects and effluent quality. Furthermore, due to limitations in hydraulic design or agitation capacity, hydraulic dead zones can easily form at the bottom of the tank, leading to suspended sludge deposition. These sediments not only reduce the effective reaction volume and lower the treatment efficiency, but long-term accumulation may also lead to anaerobic decomposition, releasing pollutants again and causing secondary pollution.

[0003] Chinese utility model patent with announcement number CN221720588U discloses an electroplating wastewater recycling and treatment device. This device uses a sliding frame and a feeding hopper to evenly feed materials into a sedimentation tank and uses a stirrer to stir the wastewater. However, this device cannot adjust the stirring intensity in real time according to the state of the wastewater, which can easily affect the flocculation of the wastewater, leading to flocculation failure. Furthermore, it cannot treat multiple sediments in the wastewater. Utility Model Content

A stirring component 2 for stirring the wastewater is slidably arranged on the sedimentation component 1. The stirring component 2 is equipped with a stirring block 204 with an adjustable stirring angle, which changes the stirring intensity of the wastewater according to the state of the wastewater, ensuring the wastewater treatment effect while avoiding breaking the already formed flocs. The stirring component 2 can also agitate the wastewater and sediment at the bottom of the treatment tank 101.

[0018] refer to Figure 1 , Figure 2 , Figure 3 The sedimentation assembly 1 shown includes a treatment tank 101. One end of the treatment tank 101 is provided with an inlet valve 105, through which wastewater enters the treatment tank 101. The other end of the treatment tank 101 is provided with an outlet valve 106, through which wastewater is discharged from the treatment tank 101.

[0019] A mounting frame 102 is slidably mounted on the upper end of the treatment tank 101. Two sets of motors 103 are mounted on the treatment tank 101. A lead screw 104 is mounted on the output shaft of the motor 103. The lead screw 104 is threadedly connected to the mounting frame 102. When the motor 103 starts, it drives the lead screw 104 to rotate. The lead screw 104 drives the mounting frame 102 to slide on the treatment tank 101, thereby adjusting the position of the mounting frame 102.

[0020] A material box 107 is provided on the side of the mounting frame 102. The material box 107 contains flocculant. In this embodiment, the flocculant is polyacrylamide. A feeding valve 108 is provided at the lower end of the material box 107. When the feeding valve 108 is opened, the polyacrylamide in the material box 107 is added to the wastewater in the treatment tank 101.

[0021] refer to Figures 3 to 5 The stirring assembly 2 shown includes a mounting block 201 that is slidably mounted on a mounting frame 102. A motor 208 is mounted on the mounting frame 102. A lead screw 209 is mounted on the output shaft of the motor 208. The lead screw 209 is threadedly connected to the mounting block 201. When the motor 208 starts, it drives the lead screw 209 to rotate. The lead screw 209 drives the mounting block 201 to slide on the mounting frame 102, thereby adjusting the position of the mounting block 201.

[0022] A stirring shaft 202 is rotatably mounted on the mounting block 201. A gear 207 is coaxially mounted on the stirring shaft 202. A motor 210 is installed inside the mounting block 201. A gear 211 is mounted on the output shaft of the motor 210. Gear 211 meshes with gear 207. When the motor 210 starts, it drives gear 211 to rotate. Gear 211 drives gear 207 to rotate. Gear 207 drives the stirring shaft 202 to rotate.

[0023] An adjusting block 206 is slidably mounted on the stirring shaft 202. A motor 212 is installed inside the stirring shaft 202. A lead screw 213 is mounted on the output shaft of the motor 212. The lead screw 213 is threadedly connected to the adjusting block 206. When the motor 212 starts, it drives the lead screw 213 to rotate, which in turn drives the adjusting block 206 to slide on the stirring shaft 202. Multiple sets of stirring blocks 204 are also rotatably mounted on the stirring shaft 202. A connecting rod 205 is rotatably mounted on each stirring block 204. One end of the connecting rod 205 is rotatably connected to the stirring block 204, and the other end is rotatably connected to the adjusting block 206. The end of the stirring block 204 away from the stirring shaft 202 has multiple openings. When the adjusting block 206 slides on the stirring shaft 202, it drives the stirring block 204 to rotate on the stirring shaft 202.

[0024] When the adjusting block 206 moves upward, the adjusting block 206 drives the multiple sets of stirring blocks 204 to deflect upward through the connecting rod 205. The distance between the opening of the multiple sets of stirring blocks 204 and the axis of the stirring shaft 202 increases, thereby increasing the stirring range of the multiple sets of stirring blocks 204 on the wastewater and improving the stirring intensity of the wastewater while the rotation speed of the stirring shaft 202 remains unchanged.

[0025] A stirring plate 203 is slidably installed at the lower end of the stirring shaft 202. A motor 214 is also installed inside the stirring shaft 202. A lead screw 215 is installed on the output shaft of the motor 214. When the motor 214 starts, it drives the lead screw 215 to rotate. The lead screw 215 drives the stirring plate 203 to slide on the stirring shaft 202. By adjusting the forward and reverse rotation of the motor 214, the stirring plate 203 can reciprocate on the stirring shaft 202. When the stirring plate 203 reciprocates on the stirring shaft 202, it stirs the wastewater and sediment at the bottom of the treatment tank 101.

[0026] Working principle: During operation, the inlet valve 105 is opened to transport wastewater to the treatment tank 101. After the transportation is completed, the inlet valve 105 is closed. Polyacrylamide is added to the treatment tank 101 according to the amount of wastewater in the treatment tank 101. The feeding valve 108 is opened to add polyacrylamide from the material box 107 into the wastewater. The motor 103 is started, which drives the lead screw 104 to rotate. The lead screw 104 drives the mounting frame 102 to slide on the treatment tank 101, so that the polyacrylamide is evenly distributed in the treatment tank 101.

[0027] While adding polyacrylamide, the wastewater in treatment tank 101 needs to be stirred. Start motor 3 210, which drives gear 211 to rotate. Gear 211 drives gear 1 207 to rotate. Gear 1 207 drives stirring shaft 202 to rotate. Stirring shaft 202 drives stirring block 204 and stirring plate 203 to rotate along the axis of stirring shaft 202, thus completing the stirring of wastewater in treatment tank 101.

[0028] Start motor 5 214, which drives lead screw 4 215 to rotate. Lead screw 4 215 drives the stirring plate 203 to slide back and forth on the stirring shaft 202. The stirring plate 203 stirs the wastewater and sediment at the bottom of the treatment tank 101.

[0029] When the position of the mounting block 201 needs to be adjusted, the motor 208 is started. The motor 208 drives the lead screw 209 to rotate. The lead screw 209 drives the mounting block 201 to slide on the mounting frame 102. The mounting block 201 drives the stirring shaft 202 to move, thereby adjusting the position of the stirring shaft 202, changing the stirring position, and improving the stirring effect.

[0030] When it is necessary to change the stirring intensity of the wastewater in the treatment tank 101, the motor 212 is started first. The motor 212 drives the lead screw 213 to rotate. The lead screw 213 drives the adjusting block 206 to slide on the stirring shaft 202. When the adjusting block 206 slides away from the stirring plate 203, the adjusting block 206 drives the stirring block 204 to rotate through the connecting rod 205. At this time, the stirring range of the multiple stirring blocks 204 on the wastewater increases, and the stirring intensity of the wastewater is increased. When the adjusting block 206 moves closer to the stirring plate 203, the adjusting block 206 drives the stirring block 204 to rotate through the connecting rod 205, and the stirring range of the multiple stirring blocks 204 on the wastewater is reduced, and the stirring intensity of the wastewater is reduced.

[0031] After the wastewater has completed flocculation, open the outlet valve 106 to discharge the wastewater into the treatment tank 101.
