Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to an integrated magnetic coagulation wastewater treatment device. Background Technology

[0002] Wastewater contains certain heavy metals. Direct reuse of this wastewater can damage the soil. Therefore, before reuse, the heavy metals in the wastewater need to be treated using an integrated magnetic coagulation wastewater treatment device. Magnetic coagulation sedimentation technology involves adding magnetic powder to a conventional coagulation sedimentation process. This allows the magnetic powder to flocculate and combine with the pollutants, enhancing the coagulation and flocculation effect. The resulting flocs are denser and more compact, achieving high-speed sedimentation. The magnetic powder can be recycled and reused through a magnetic drum. Existing technology publication number CN112551797A discloses a magnetic coagulation sedimentation treatment device and its treatment process for pharmaceutical wastewater, comprising a first rapid mixing tank, a second rapid mixing tank, a third rapid mixing tank, a fourth flocculation tank, a clarification sedimentation tank, and a magnetic powder recovery system connected in sequence. Air stirring devices are installed in the first, second, and third rapid mixing tanks; a mechanical stirring device is installed in the fourth flocculation tank; a flocculation dosing pipe is connected to the first rapid mixing tank; magnetic powder, after passing through the magnetic powder recovery system, is added to the second rapid mixing tank; and a coagulant aid dosing pipe is connected to the third rapid mixing tank. However, because the density of magnetic powder is greater than that of water, after the magnetic powder is added to the water, it continuously accumulates at the bottom of the reaction chamber. Although there is a stirring mechanism, it can only rotate the magnetic powder horizontally and cannot change the downward movement trend of the magnetic powder. Therefore, this results in uneven vertical distribution of the magnetic powder, thus affecting the flocculation effect of the magnetic powder on pollutants. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an integrated magnetic coagulation wastewater treatment device that can uniformly mix magnetic powder and wastewater, thereby improving the utilization rate of magnetic powder and the flocculation effect on pollutants.

[0004] This utility model discloses an integrated magnetic coagulation wastewater treatment device, comprising a mixing tank, multiple connecting columns, a collection tank, multiple upright legs, a base, an inlet pipe, multiple baffles, a feeding assembly, a lifting assembly, a stirring assembly, and a collection and discharge assembly. The bottom of the mixing tank is connected to the top of the collection tank via connecting columns. Multiple upright legs are installed at the four corners of the bottom of the collection tank, and the bottom of the upright legs is fixedly connected to the top of the base. Multiple baffles are alternately installed on the upper and lower side walls of the mixing tank, dividing the interior of the mixing tank into multiple chambers. An inlet pipe is connected to the lower part of the left side wall of the mixing tank, and a feeding assembly is connected to the top of the mixing tank. The system consists of a lifting component installed inside the mixing chamber, an agitator and a lifting component installed alternately inside the chamber, and a collection and discharge component installed at the bottom of the collection tank. Wastewater enters the left chamber of the mixing tank through an inlet pipe. Magnetic powder is evenly fed into the chamber through a feeding component. The lifting and agitator components ensure uniform mixing of the magnetic powder and wastewater, resulting in a more even vertical distribution of the magnetic powder, improving its utilization rate and flocculation effect on pollutants. The collection and discharge component collects the sludge for further processing, while the magnetic powder is recycled and reused, enhancing its practicality.

[0005] Preferably, the feeding assembly includes a feeding cylinder, two feeding pipes, a rotating rod, two spiral conveyor blades, and a geared motor. The feeding cylinder is fixedly installed on the top of the mixing chamber. Feeding pipes are connected to the front and rear ends of the feeding cylinder, and the output ends of the feeding pipes are connected to the inside of the mixing chamber. A feeding port is provided at the top of the feeding cylinder. The rotating rod is rotatably installed inside the feeding cylinder, and spiral conveyor blades are symmetrically installed on the left and right ends of the rotating rod. The input end of the left side of the rotating rod is connected to the output end of the geared motor. When the geared motor is started, the spiral conveyor blades are driven to rotate through the rotating rod, and magnetic powder is added to the feeding cylinder through the feeding port. The spiral conveyor blades push the magnetic powder, so that the magnetic powder is evenly distributed into the chamber of the mixing chamber through the feeding pipes, ensuring uniform distribution of magnetic powder and improving the utilization rate of magnetic powder.

[0006] Preferably, the lifting assembly includes two drive motors, lifting rods, two helical guide vanes, and two sets of stirring rods. The drive motors are fixedly installed at the bottom of the mixing tank. The output end of the drive motor passes through the bottom of the mixing tank and is connected to the lifting rods. The two lifting rods are installed alternately in different chambers. Helical guide vanes are installed on the outer wall of the lifting rods, and multiple stirring rods are installed on the top of the lifting rods. When the drive motors are started, the lifting rods rotate, which in turn drives the helical guide vanes to rotate, conveying the lower sewage and magnetic powder upwards. This ensures that the flocculant and sewage, as well as the magnetic powder and sewage, are fully mixed, resulting in a more uniform vertical distribution of the magnetic powder. This improves the utilization rate of the magnetic powder and the flocculation effect on pollutants.

[0007] Preferably, the stirring assembly includes two horizontal shafts, two sets of stirring crossbars, two drive wheels, a support plate, a second geared motor, and a transmission belt. The two horizontal shafts and the lifting rod are alternately installed inside the mixing chamber. Multiple stirring crossbars are installed on the outer wall of the horizontal shafts. A drive wheel is installed at the rear input end of the horizontal shaft. The two drive wheels are connected by a transmission belt. The input end of one of the drive wheels is connected to the output end of the second geared motor. The second geared motor is installed on the rear side wall of the mixing chamber through the support plate. When the second geared motor is started, it drives the two horizontal shafts to rotate through the drive wheels and the transmission belt. The horizontal shafts drive the multiple sets of stirring crossbars to rotate, stirring the sewage in the chamber. The sewage is stirred and mixed multiple times, which improves the utilization rate of magnetic powder and the flocculation effect on pollutants.

[0008] Preferably, it also includes multiple connecting pipes, two guide plates, a filter screen, and a purified water pipe. The inlet ends of the multiple connecting pipes are connected to the lower right side wall of the mixing tank, and valves are installed on the connecting pipes. The outlet ends of the connecting pipes are connected to the interior of the collection tank. Guide plates are installed at the lower left and right ends of the collection tank. A filter screen is connected between the upper part of the left guide plate and the collection tank. A purified water pipe is connected to the left side wall of the collection tank. The mixed wastewater is input into the collection tank through the connecting pipes, and the wastewater is guided by the left guide plate. At the same time, the right guide plate prevents the wastewater from washing up the settled sludge and magnetic powder. The purified water is discharged from the purified water pipe and filtered again by the filter screen.

[0009] Preferably, the collection and discharge assembly includes a collection hopper, a push shaft, spiral push blades, a servo motor, and a drain pipe. The collection hopper is connected to the bottom of the collection box, and the lower part of the collection hopper is configured as a collection cylinder. The front end of the collection cylinder is connected to the drain pipe. The push shaft is rotatably installed in the collection cylinder. The rear input end of the push shaft is connected to the output end of the servo motor. Spiral push blades are installed on the outer wall of the push shaft. The flocculated sludge and magnetic powder settle downwards and accumulate in the collection hopper. The servo motor is started to drive the spiral push blades to rotate through the push shaft, pushing them forward for collection. The drain pipe is opened periodically, and the sludge and magnetic powder are sucked out by a suction pump. Then, the sludge and magnetic powder are separated by an existing high-speed shear and magnetic powder separator. The sludge is further processed after collection, while the magnetic powder is recycled and put back into the mixing tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: wastewater is input into the left chamber of the mixing tank through the inlet pipe, and magnetic powder is evenly input into the chamber through the feeding component. Through the lifting component and the stirring component, the magnetic powder and wastewater are evenly mixed, which can make the magnetic powder more evenly distributed in the vertical direction, improve the utilization rate of magnetic powder and the flocculation effect on pollutants. The sludge is collected by the collection and discharge component for further processing, and the magnetic powder is recycled and reused, improving its practicality. Attached Figure Description
