Description

Technical Field

[0001] This utility model relates to the field of heavy metal ion adsorption in electroplating wastewater, specifically a heavy metal ion adsorption and separation device for electroplating wastewater. Background Technology

[0002] Electroplating plays a vital role in the manufacturing industry, widely used in automobiles, electronics, aerospace, and other fields, providing crucial support for the development of modern industry. However, the wastewater generated during electroplating contains large amounts of heavy metal ions, such as chromium, nickel, copper, and zinc, which pose serious threats to the environment and human health. Therefore, the treatment of electroplating wastewater is particularly urgent. Currently, the main methods for treating electroplating wastewater include chemical precipitation, membrane separation, and ion exchange. Chemical precipitation is simple to operate and has low cost, but its treatment efficiency is limited and it is prone to secondary pollution. Membrane separation produces no secondary pollution, requires little space, and has high treatment efficiency, but the membranes are easily fouled and damaged, requiring regular replacement or cleaning, resulting in higher costs. Utility Model Content

[0003] The purpose of this invention is to provide a heavy metal ion adsorption and separation device for electroplating wastewater to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A heavy metal ion adsorption and separation device for electroplating wastewater includes a storage tank. A top seal is fixedly connected to the top of the storage tank, and a motor is fixedly connected to the top of the top seal. A rotating shaft is rotatably connected to the drive end of the motor. A connecting piece is fixedly connected to the outer wall of the rotating shaft. An agitator is fixedly connected to the outer wall of the connecting piece away from the rotating shaft. A water inlet pipe 1 and a water inlet pipe 2 are respectively connected and installed at the upper and lower parts of the outer wall of the storage tank. A water pipe is installed at the bottom of the storage tank, and a connector is fixedly connected to the outer wall of the water pipe. A water pump is fixedly connected to the end of the water pipe away from the storage tank, and an activated carbon box is installed at the end of the water pump away from the connector.

[0006] As a further embodiment of this utility model: the inner frame of the activated carbon box is equipped with isolation plates at both the upper and lower parts, a cylinder is installed at the center of the upper surface of the isolation plate, and a beam frame is installed on the top of the cylinder.

[0007] As a further embodiment of this utility model: both ends of the beam frame are fixedly connected to a support frame, and the top front and rear parts of the support frame are fixedly connected to spring members, and the top of the spring members is fixedly connected to a fixing block.

[0008] As a further embodiment of this utility model: the discharge end of the activated carbon box is equipped with an inclined trough seat, the trough opening of the inclined trough seat is slidably connected to a gate, the top of the gate is fixedly connected to an electric push rod, and the top of the electric push rod is fixedly connected to a beam frame two.

[0009] As a further improvement of this utility model: a bent pipe is connected to the upper surface of the isolation plate, and a conduit is fixedly connected to the end of the bent pipe away from the isolation plate.

[0010] As a further embodiment of this utility model: the supporting end of the savings tank is fixedly connected to a second support frame, and there are three sets of the second support frames. The three sets of the second support frames have the same structure, and a base plate is installed at the bottom of the savings tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the liquid containing heavy metals enters the activated carbon box and is positioned between two sets of isolation plates. Continuous operation of a control cylinder pushes the isolation plates within the activated carbon box, causing them to compress. This compression of the isolation plates also compresses the activated carbon box, causing it to contract via a spring connected to a fixed block. When the cylinder retracts, the spring's reaction force pushes the activated carbon box upwards, ensuring full contact between the heavy metal liquid at the isolation plates and the activated carbon within the box. An electric actuator then pulls the gate at the sloping trough opening to discharge the used activated carbon. This design features an optimized structure and a more rational design.

A water pump 9 is fixedly connected to the end of the water pipe away from the storage tank 1. An activated carbon box 10 is installed at the end of the water pump 9 away from the connector 8.

[0019] The inner frame of the activated carbon box 10 is equipped with isolation plates 21 at both the top and bottom. A cylinder 19 is installed at the center of the upper surface of the isolation plate 21, and a beam frame 15 is installed on the top of the cylinder 19.
