This wastewater causes damage to the environment and human health. Therefore, effective treatment of electroplating wastewater has become an urgent problem to be solved currently.

[0003] When the existing equipment filters electroplating wastewater, usually only a single filter plate is used for filtration. Since the wastewater will directly impact the filter plate under the action of gravity when entering the tank body, large-volume impurities in the wastewater will directly pass through the filter plate due to the impact force, and it is easy to damage the filter plate, resulting in poor filtration effect. Over time, the deposits inside the tank body are difficult to clean. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electroplating wastewater filter tank.

A mixing mechanism is arranged at one end of the rotating shaft far away from the motor. A sliding groove is opened on the inner wall of the lower tank body. A limiting rod is fixedly connected to the bottom wall of the sliding groove. A buffer mechanism is arranged on the limiting rod. The bottom of the lower tank body is fixedly connected with a bottom plate. The bottom of the bottom plate is rotatably connected with universal wheels.

[0007] Furthermore, the limiting ring is rotatably connected with the top of the top cover. The sliding grooves are symmetrically distributed with the lower tank body as the axis. An installation plate one is fixedly connected to the outer surface of the lower tank body. A sliding groove fixing bolt is fixedly connected to the upper surface of the installation plate one. A fixing nut is meshed and rotatably connected to the outer surface of the fixing bolt.

[0008] Furthermore, a sealing plate is fixedly connected to the inner wall of the upper tank body. The sealing plate is slidably connected to the inner wall of the chute. An installation plate II is fixedly connected to the outer surface of the upper tank body. The installation plate II is in contact connection with the installation plate I, and the installation plate II is slidably connected to the fixing bolt.

[0009] Furthermore, the mixing mechanism includes a turntable. The upper surface of the turntable is fixedly connected to the end of the rotating shaft, and a convex ring is fixedly connected to the outer surface of the turntable.

[0010] Furthermore, a grid plate is fixedly connected to the upper surface of the turntable. The grid plates are circumferentially and arrayed around the turntable as the axis, and a number of fine holes are formed on the outer surface of the grid plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the rotation of the turntable causes the waste water to be carried upward to the inner wall of the upper tank body by inertia, so that the waste water spills onto the filter plate. After being impacted by the waste water, the filter plate sinks, so that the sliding ring I compresses the telescopic spring. Further, the impact force received by the filter plate can be released, so that the impact of the waste water when contacting the surface of the filter plate is greatly reduced, thereby avoiding large-volume impurities in the waste water from passing through the filter plate and entering the inner part of the lower tank body to cause blockage, and improving the filtering effect.

[0015] 2. In the utility model, by starting the motor, the turntable and the grid plate on its surface rotate synchronously. Electroplating waste water is injected into the tank body through the water inlet pipe, and an acidic chemical reaction agent is put into the tank body through the feeding pipe. Under the rotation of the grid plate, the electroplating waste water will be fully mixed with the reaction agent, so that the heavy metal substances in the electroplating waste water react with the reaction agent, which can greatly reduce the heavy metals in the electroplating waste water. By loosening the fixing nut, the upper tank body can be further removed from the top of the lower tank body, which facilitates the opening of the tank body, so that the cleaning is more convenient and the cleaning effect is more intuitive.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings
