Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, specifically a purification treatment device for electroplating wastewater treatment. Background Technology

[0002] Electroplating wastewater is generated during the electroplating process, mainly originating from electrolytes, cleaning water, and discharged rinsing solutions. This wastewater typically contains various metal ions and some chemical additives. If these components are discharged directly without treatment, they can cause serious pollution to the aquatic environment and affect the growth of aquatic organisms; therefore, electroplating wastewater purification treatment is necessary.

[0003] Existing treatment methods typically employ wastewater treatment tanks and internally installed mixing mechanisms to stir and mix the reagents and wastewater to achieve a purification effect. However, existing mixing mechanisms are usually fixed installations, making it difficult to quickly and evenly mix the wastewater, which increases the reaction time. Furthermore, it is not convenient to add the reagents evenly to the tank during treatment, further reducing the reaction rate and effectiveness of the purification reagents and wastewater. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] In view of the above situation and to overcome the current technical defects, this utility model provides a purification treatment device for electroplating wastewater that is easy to use. This device can fully stir the wastewater in the wastewater treatment tank and simultaneously add and mix the chemical solution evenly with the wastewater, thereby improving the efficiency of wastewater treatment.

[0005] The technical solution adopted by this utility model is as follows: This solution provides a purification treatment equipment for electroplating wastewater treatment, including a wastewater treatment tank, a frame, a stirring assembly, and a chemical reagent tank. A guide seat is installed at the upper end of the perimeter of the wastewater treatment tank. The frame is slidably installed on the guide seat and its upper end is located above the wastewater treatment tank. A lead screw and a guide rod are respectively installed on the top of the frame. A servo motor for driving the lead screw is installed on one side of the frame. A mounting plate is threaded onto the lead screw. The mounting plate is guided and limited by the guide rod. The stirring assembly is installed on the mounting plate and its lower end extends into the wastewater treatment tank. The chemical reagent tank is installed on one side of the upper end of the mounting plate.

[0006] The servo motor drives the lead screw to rotate, causing the mounting plate to move laterally along the guide rod under the guidance and limit of the guide rod, so as to uniformly stir and spray the chemicals in the wastewater treatment tank.

[0007] Preferred technical solution 1: Hydraulic cylinders are symmetrically provided at the lower ends of both sides of the wastewater treatment tank. The output shaft of the hydraulic cylinder is connected to the lower end of the frame. The hydraulic cylinder drives the frame to move up and down, which is used to adjust the height of the stirring assembly.

[0008] Preferred technical solution 2: The stirring assembly includes a forward and reverse reversible stirring motor and a stirring tube. The forward and reverse reversible stirring motor is mounted on one side of the upper end of the mounting plate. A bearing sleeve is provided in the middle of the mounting plate. The stirring tube is rotatably mounted on the bearing sleeve and its lower end extends into the wastewater treatment tank. The output shaft of the forward and reverse reversible stirring motor and the stirring tube are both provided with mutually compatible gears, and the gears mesh with each other.

[0009] Preferred technical solution 3: The chemical reagent tank is connected to a conduit via a liquid pump, and the upper end of the stirring tube is provided with a rotary joint, and the conduit is connected to the rotary joint.

[0010] Preferred technical solution four: The lower end of the stirring tube is provided with multiple sets of stirring blades at intervals, and the lower end of the stirring tube is provided with multiple sets of spraying holes.

[0011] Preferred technical solution five: An L-shaped inlet is installed at the middle of the front end of the wastewater treatment tank. A detachable filter screen is sealed and inserted into the inlet. A drain valve is provided on one side of the lower end of the inlet, and a liquid drain valve is provided on one side of the lower end of the wastewater treatment tank.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. The hydraulic cylinder can drive the frame to move up and down, thereby adjusting the height of the mixing components according to the depth of the wastewater treatment tank and the mixing requirements, ensuring effective mixing at different water levels and depths. The servo motor drives the lead screw to move the mixing components and chemical tank laterally, thereby achieving uniform mixing and chemical spraying of the wastewater treatment tank, improving the uniformity of wastewater treatment, and ensuring thorough mixing of wastewater and chemicals.

[0014] 2. The forward and reverse stirring motor can drive the stirring blades to stir in both directions under the rotation of the gear-driven stirring tube. The chemical agent is introduced from the chemical agent tank into the stirring tube by the chemical agent pump and sprayed evenly from the spraying hole. Combined with the stirring blades, the utilization efficiency of the chemical agent is further improved.

[0015] 3. With its inlet and detachable filter screen, it can filter particulate matter and impurities in wastewater. The detachable design of the filter screen makes it easy to clean, maintain and replace daily, ensuring the wastewater filtration effect. Attached Figure Description
