Description

Technical Field

[0001] This utility model relates to the field of wastewater inlet and drainage technology, specifically to an inlet and drainage mechanism for electroplating wastewater tanks. Background Technology

[0002] Electroplating wastewater is complex and highly hazardous due to its content of toxic and harmful substances such as heavy metals, cyanides, acids, alkalis, and organic matter. The composition of wastewater varies greatly depending on the electroplating process, and the mixed discharge of wastewater by some enterprises further increases the difficulty of treatment. Traditional physicochemical methods (such as neutralization precipitation and oxidation-reduction) require strict pH control, are complex to operate, and have high reagent costs. Physicochemical methods (such as activated carbon adsorption and membrane separation) have problems such as easy saturation of activated carbon, membrane fouling, and high costs. Biological methods have limited effectiveness in treating high-concentration heavy metal wastewater, and the cultivation conditions for functional bacteria are demanding. At the same time, industry regulations require the classified collection and pretreatment of electroplating wastewater, and emission standards are becoming increasingly stringent, advocating resource utilization and zero discharge. However, existing single treatment technologies are difficult to remove multiple pollutants simultaneously, and combined processes are long and costly. In addition, traditional processes rely on manual operation, which can lead to fluctuations in treatment effects. Existing filtration equipment is prone to clogging and has high maintenance costs. In view of these issues, this case study was conducted in depth to address the above problems. Utility Model Content

[0009] Beneficial effects This utility model provides an inlet and outlet drainage mechanism for an electroplating wastewater tank.

[0013] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0015] Please see Figure 1-2 Electroplating wastewater contains toxic and harmful substances such as heavy metals (e.g., chromium, nickel, copper), cyanide, acids, alkalis, and organic matter, posing risks of teratogenicity, carcinogenicity, and mutagenicity. Direct discharge without treatment will seriously pollute the environment. The composition of wastewater generated by different electroplating processes (e.g., zinc plating, chromium plating, nickel plating) varies greatly, requiring separate collection and treatment. However, some companies mix wastewater due to equipment or management deficiencies, increasing the difficulty of treatment. Traditional processes cannot remove heavy metals, organic matter, and salts simultaneously, requiring a combination of multiple technologies, but this results in long processes and high costs. Therefore, this application protects an inlet and outlet drainage mechanism for an electroplating wastewater tank 1. The electroplating liquid is filtered through a filter module on the eye-shaped limiting support block 2 inside the electroplating wastewater tank 1. First, the expansion airbag 11 is inflated by the air pump 12, causing it to expand and raising the liquid level inside the electroplating wastewater tank 1. Through the siphon principle, the liquid is guided to the inside of the upward drainage pipe 14, which then guides the liquid to the inside of the filter inner box 4. Multiple refractive plates 5 cooperate within the filter inner box 4, causing the flow inside the filter inner box 4 to form an S-shape. Filtering is performed through the filter modules between the multiple refractive plates 5, with siphon principle guiding the filtration step-by-step. Simultaneously, the lifting rail 8 on the J-shaped limiting drainage pipe 6 moves, driving the L-shaped lifting block 9 to move stably up and down. The L-shaped lifting block 9 then drives the set on it... The U-shaped block 10 is raised and lowered stably by the lifting guide pipe 7 on the U-shaped block 10, so that the lifting guide pipe 7 is inserted into the inner side of the filter inner box 4, and thus into the electroplating solution after multiple filtrations. At the same time, the horizontal screw module 16 on the filter inner box 4 runs, driving the L-shaped cleaning block 17 on it. The lifting electromagnets on the L-shaped cleaning block 17 are energized, and the lifting electromagnets stabilize and adjust the lifting magnets. The lifting magnets drive the lifting limit block 19 on it to rise and fall stably along the lifting groove 18 on the inner side of the L-shaped cleaning block 17. The lifting limit block 19 drives the cleaning roller brush on it to rise and fall stably. The cleaning drive motor runs, driving the rotation and height adjustment of the cleaning roller brush, so as to rotate the filter screen group 3 on the mesh-shaped limit support block 2. In summary, during the operation of the inlet and outlet mechanism of the electroplating wastewater tank 1, the air pump 12 first inflates the expansion bladder 11, causing it to expand and raising the liquid level in the electroplating wastewater tank 1. Utilizing the siphon principle, the liquid flows through the upward drainage pipe 14 into the inner filter chamber 4. Under the action of multiple refractive plates 5 within the chamber, the liquid flows in an S-shape, passing through the filter modules between the refractive plates 5 one by one. Next, the lifting rail 8 on the J-shaped limiting drainage pipe drives the L-shaped lifting block, the fitted loop block 10, and the lifting drainage pipe 7 to rise and fall stably, inserting the lifting drainage pipe 7 into the electroplating solution after multiple filtrations. Simultaneously, the horizontal screw module 16 on the inner filter chamber 4 drives the L-shaped cleaning block to move. When the lifting electromagnet on the cleaning block is energized, the lifting magnet drives the lifting limit block 19 to move stably up and down along the lifting groove 18, which in turn drives the cleaning roller brush to move stably up and down. Then, the cleaning drive motor drives the cleaning roller brush to rotate and adjust its height, realizing the rotating roller brush on the filter screen group 3 on the eye-shaped limit support block 2. Throughout the process, the control box outside the electroplating wastewater pool 1 is electrically connected to the horizontal screw module 16, the cleaning drive motor, the lifting electromagnet, the air pump 12, the liquid level gauge 13, and the solenoid valve on the drain outlet, so as to uniformly control each component.
