Description

Technical Field

[0001] The present application relates to the technical field of heavy metal wastewater treatment, and specifically to a heavy metal wastewater deep purification treatment equipment. Background Art

[0002] Wastewater containing heavy metals, including cadmium, nickel, mercury, zinc, etc., is discharged during industrial production. This type of wastewater mainly comes from mining, smelting, electrolysis, electroplating, pesticides, medicines, paints, pigments, etc. Since heavy metals cannot be decomposed and destroyed, they can only be transferred to other locations and their physical and chemical forms, so they are extremely harmful to the environment.

[0003] Application No. 202022670429.5 discloses a deep treatment equipment for antimony and arsenic heavy metal wastewater, including a bottom plate, a sedimentation chamber, a transition pipe, an outlet pipe and a push block, etc., a first pulley, a second pulley, a stirring roller, a water pump and a feeding hopper. When treating wastewater, it can be fully stirred, and the process flow ensures that the treatment speed is improved. The pipe buckle fixes the liquid inlet pipe to prevent the stirring roller from rotating and driving the liquid inlet pipe to damage it. The effect of multiple feeding treatment is significantly improved. The set gear drives the rack to move and then drives the push block to move to clean the transition pipe and the outlet pipe, so as to prevent the pipeline from being blocked by solid impurities produced by chemical combination and affecting the treatment and filtration effect.

[0004] However, in use, there are the following defects:

[0005] Although a water pump is used to pump the wastewater into the next reaction chamber for further stirring, since the wastewater and the precipitated heavy metal particles are not separated, the heavy metals will also be sucked into the water pump, which may cause the liquid inlet pipe to be blocked and affect the normal operation of the device. Utility Model Content

[0006] The purpose of the present application is to provide a heavy metal wastewater deep purification treatment equipment, which solves the problem proposed in the background technology that although a water pump is used to pump the wastewater into the next reaction chamber for subsequent stirring, the wastewater and the precipitated heavy metal particles are not separated, so that the heavy metals will also be sucked into the water pump, which may cause the liquid inlet pipe to be blocked and affect the normal operation of the device.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a heavy metal wastewater deep purification treatment equipment, comprising a top box, a mixing drum, a partition, a cleaning tank and a driving motor, a filling port is provided at the top of the top box, and a mixing drum is fixedly installed at the bottom of the top box, the top of the mixing drum is connected to the filling port, a side slide groove is provided on the side wall of the top box, an activated carbon tank is laterally slidably connected to the inner side of the side slide groove, a driving motor is fixedly installed at the bottom of the mixing drum, and a transmission rod is fixedly installed at the center of the inner bottom of the mixing drum, a number of stirring rods are fixedly connected to the side wall of the transmission rod, the inner side wall of the mixing drum is fixedly connected with partitions and interception net frames from top to bottom, and the transmission rod passes through the center of the surface of the partition and the interception net frame from below, and a discharge pipe is fixedly connected and connected to the right side of the bottom of the mixing drum.

[0008] In this technical solution, wastewater is poured from the filling port, and activated carbon is placed in the activated carbon tank. When the wastewater passes through, the activated carbon can adsorb heavy metals in the wastewater, thereby reducing the heavy metal content in the wastewater and reducing the pressure for the stirring and sedimentation below. After the wastewater reaches the mixing drum, the drive motor is powered on and starts to drive the transmission rod and the stirring rod to rotate, and the flocculant discharged from the flocculant storage box along the discharge pipe is used to stir the wastewater, so that the heavy metals in the wastewater are precipitated in particles, thereby improving the heavy metal separation efficiency of the device. At the same time, heavy metals can be cleaned through the cleaning tank, cleaning brush and sealing plug. After the wastewater is stirred and precipitated, the electric valve is controlled to open, and the wastewater and sediment fall through the opening. The wastewater passes through the interception mesh frame and leaves the discharge pipe, while the heavy metal precipitation particles are intercepted by the interception mesh frame and gradually enter the cleaning tank under the rotating cleaning of the cleaning brush under the stirring rod. After the wastewater in the cleaning tank is drained through the drain hole, the sealing plug is pulled out and the precipitation particles can be cleaned, thereby improving the heavy metal separation efficiency of the device for wastewater.

[0009] As an optional solution of the technical solution of the present application, a cleaning groove is fixedly installed on the left side of the bottom of the intercepting net frame, the left end of the cleaning groove is connected to the outer wall of the mixing drum, and a sealing plug is movably inserted and connected at the opening of the cleaning groove, and a number of drainage holes are evenly opened at the bottom of the cleaning groove.

[0010] As an optional solution of the technical solution of the present application, a cleaning brush is fixedly connected to the bottom of the lowermost stirring rod.

[0011] As an optional solution of the technical solution of the present application, a supporting net is detachably installed on the inner wall of the activated carbon tank.

[0013] As an optional solution of the technical solution of the present application, openings are provided on both sides of the surface of the partition, and the bottom of the partition below the opening is fixedly connected and communicated with an electric valve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can separate heavy metals through an activated carbon tank, a stirring rod and a flocculant storage box. Activated carbon is placed in the activated carbon tank. When wastewater passes through, the activated carbon can adsorb heavy metals in the wastewater, thereby reducing the heavy metal content in the wastewater and reducing the pressure for the stirring and sedimentation below. After the wastewater reaches the mixing drum, the drive motor is powered on and started to drive the transmission rod and the stirring rod to rotate, and the flocculant discharged from the flocculant storage box along the discharge pipe is used to stir the wastewater, so that the heavy metals in the wastewater are precipitated in particles, thereby improving the heavy metal separation efficiency of the device.

[0016] 2. Heavy metals can be cleaned by cleaning the tank, cleaning brush and sealing plug. After the wastewater is stirred and precipitated, the electric valve is controlled to open, and the wastewater and sediment fall through the opening. The wastewater passes through the interception mesh frame and leaves the discharge pipe, while the heavy metal precipitation particles are intercepted by the interception mesh frame and gradually enter the cleaning tank under the rotating cleaning of the cleaning brush under the stirring rod. After the wastewater in the cleaning tank is drained through the drain hole, the sealing plug is pulled out and the precipitation particles can be cleaned, thereby improving the heavy metal separation efficiency of the device for wastewater.
