Description

Technical Field

[0001] This utility model relates to the field of heavy metal polluted wastewater treatment equipment, and more specifically, to a heavy metal polluted wastewater treatment equipment. Background Technology

[0002] Metal pollution refers to environmental pollution caused by heavy metals or their compounds. It is mainly caused by human factors such as mining, exhaust gas emissions, sewage irrigation, and the use of heavy metal products. Human activities lead to an increase in the content of heavy metals in the environment, exceeding the normal range, and causing the deterioration of environmental quality.

[0003] According to the Chinese Utility Model Patent Publication No. CN212540362U, a device for monitoring and treating industrial heavy metal wastewater quality is proposed. It uses a rotating transmission rod to separate the locking rod from the locking groove and move the positioning block upward, which in turn moves the sealing plate upward, so that the sealing plate no longer seals the hand hole. This makes it convenient to add filler to the inside of the treatment device. However, after the material is poured in, the already precipitated heavy metal substances will become active again. At the same time, the material cannot be fully diffused in the wastewater, resulting in the wastewater not being effectively treated.

[0004] Furthermore, based on existing technology patents, such as the authorized announcement number CN221771779U, this utility model relates to the field of wastewater treatment technology and discloses a heavy metal polluted wastewater treatment device, including a sedimentation component, a treatment component, a liquid supply tank, and a wastewater tank. The sedimentation component includes a sedimentation tank with a sedimentation treatment pool on it, a drainage trough inside the sedimentation treatment pool, and a water conveying trough on the sedimentation treatment pool. The drainage trough and the water conveying trough are connected. A chelating precipitant is delivered into the wastewater treatment tank through a liquid conveying pipe. After entering the annular pipe and the diversion pipe to form a pressure tank, it is evenly sprayed onto the side of the U-shaped pipe through a nozzle. At the same time, the U-shaped pipe delivers heavy metal wastewater into the wastewater treatment tank. After the wastewater forms pressure at the front end of the pipe, it is sprayed out through the spray hole, fully mixed with the sprayed chelating precipitant, and falls into the inside of the water collection tank. As the chelating precipitant and wastewater are continuously injected into the tank, the wastewater inside the water collection tank is in a surging state, further improving the mixing effect of the chelating precipitant and wastewater.

[0005] In the aforementioned patent, the precipitant is effectively and uniformly fused by being sprayed out through multiple sets of built-in pipes and nozzles. Its complex pipe design has a complex structure of multiple nozzles, and the pipes are inconvenient to set up, easy to be blocked and corroded. When adding precipitant, the uniform processing mechanism is complex and inconvenient. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a heavy metal polluted wastewater treatment device. By using a stirring component to stir the precipitant to accelerate fusion, the device achieves uniform fusion and treatment. It is simple in structure, not easily damaged or clogged, low in cost, and easy to use.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A heavy metal polluted wastewater treatment device includes a sedimentation tank, characterized in that: a support platform is fixed to the inner surface of the sedimentation tank, a wastewater treatment cylinder is fixedly connected to the upper surface of the support platform, and a drive motor is fixedly connected to the upper surface of the wastewater treatment cylinder (the motor's forward and reverse rotation represent clockwise and counterclockwise rotation. Clockwise rotation is forward rotation, and counterclockwise rotation is reverse rotation. According to the forward and reverse rotation control circuit diagram and its principle analysis, to achieve forward and reverse rotation of the motor, any two phases of the three-phase power supply lines connected to the motor can be interchanged to achieve the reverse rotation). A rotating disk is fixedly connected to the outer surface of the drive shaft of the drive motor, and a stirring blade is fixedly connected to the outer surface of the rotating disk. A support protrusion is fixedly connected to one end of the inner surface of the wastewater treatment cylinder. A lifting disk is threadedly connected to the outer surface of the drive shaft. The lifting disk has openings on its surface and recesses on its outer side. By using a stirring assembly to stir the precipitant, the fusion is accelerated, and the fusion is uniform. The device is simple in structure, not easily damaged or clogged, low in cost, and easy to use.

[0009] Furthermore, the notches are evenly distributed on the outer surface of the lifting plate, and the inner surface of one side of the notch of the lifting plate is slidably engaged with the outer surface of the supporting protrusion.

[0010] Furthermore, the openings are a combination of round holes and triangular holes, which are evenly and densely distributed on the upper surface of the lifting plate.

[0011] Furthermore, a feed inlet is provided on one side of the upper surface of the wastewater treatment cylinder, and a wastewater inlet pipe is provided on the other side.

[0012] Furthermore, a wastewater outlet pipe is provided on one side of the lower end of the wastewater treatment cylinder, and a valve is provided on the surface of the wastewater outlet pipe.

[0013] Furthermore, a first conduit and a second conduit are provided on the side of the sedimentation treatment tank.

[0015] Compared with existing technologies, the advantages of this utility model are:
