Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic separation equipment technology, and specifically provides a magnetic separation wastewater treatment system. Background Technology
[0002] Supermagnetic separation water purification technology is mainly used to remove non-magnetic or weakly magnetic particulate pollutants from water. Its technical principle is based on traditional coagulation technology. By adding a magnetically conductive medium, the chemical flocs formed during the coagulation process are inoculated with magnetic media and then separated from the water by an external magnetic field. In other words, the magnetic separation process replaces the sedimentation separation process in the original coagulation technology, thereby achieving rapid and efficient water purification.
[0003] Supermagnetic separation water purification systems generally consist of flocculation equipment, magnetic separation equipment, magnetic recovery equipment, and dosing equipment. Magnetic separation equipment, as the core of supermagnetic water purification technology, is crucial for separating pollutants from water. Regarding the process of magnetic floc adsorption by the magnetic separator, the influent water flow affects the adsorption efficiency of the separator, thus directly impacting the quality of the purified water.
[0004] Because the size of the inlet opening of the magnetic separator is the same as the thickness of the disk rollers arranged internally, and the effluent from the flocculation equipment enters the magnetic separator, the flow channel widens and turbulence easily occurs, resulting in uneven water distribution in the magnetic separator. At the same time, the utilization rate of the disks at both ends of the magnetic separator is not high, which in turn affects the overall adsorption and purification quality and efficiency of the magnetic separator. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a treatment system that reduces uneven water distribution during the process from the effluent of the flocculation equipment to the influent of the magnetic separation equipment. The specific technical solution is as follows:
[0006] A magnetic separation wastewater treatment system includes a flocculation device and a magnetic separation device. The flocculation device includes a flocculation tank, and the magnetic separation device includes an ultramagnetic generator. The outlet of the flocculation tank is connected to the inlet of the ultramagnetic generator. The inlet width of the ultramagnetic generator is less than or equal to the outlet width of the flocculation tank, and the inlet of the ultramagnetic generator is positioned directly opposite the inlet of the ultramagnetic generator.
[0007] In this scheme, by limiting the width of the inlet of the super magnetic host in the magnetic separation equipment, the wastewater that is evenly distributed in the flocculation tank can smoothly enter the super magnetic host without causing turbulence due to the sudden widening of the flow channel. It also allows all the disks in the super magnetic host, including the two outermost disks, to process wastewater with similar magnetic floc density at the same time, ensuring disk utilization and improving the overall water purification efficiency of the magnetic separation equipment.
[0008] On the other hand, while ensuring that the wastewater entering the supermagnetic generator does not experience turbulence, it is also necessary to ensure that the wastewater output from the flocculation equipment is evenly distributed and flows stably. Therefore, the width of the flocculation tank is equal to the width of its outlet. This prevents the wastewater output from the flocculation tank from becoming turbulent due to obstruction by the tank wall at the outlet, ensuring a uniform and stable water flow, which in turn guarantees a stable subsequent water inflow.
[0009] Because the flocculation tank typically uses paddles to agitate and mix the water, excessive agitation can cause the water flowing into the magnetic separator to deflect towards the disks, thus reducing disk utilization. To mitigate this, a guide vane is installed at the outlet of the flocculation tank. This guide vane directs the deflected water flow, ensuring that the wastewater from the flocculation tank is fed directly into the super magnetoresistive unit, allowing all disks to operate effectively.
[0010] Preferably, the guide vanes are evenly spaced, and the starting positions of the guide vanes gradually move away from the flocculation device. The direction in which the guide vanes move away is opposite to the deflection direction of the effluent from the outlet of the flocculation tank, ensuring that the water flow with an initial deflection direction can be uniformly guided by the guide vanes.
[0011] Preferably, the magnetic separation device is further provided with a disk roller formed by multiple disks stacked and arranged with uniform gaps.
[0012] Since the inlet width of the supermagnetic generator must be equal to the thickness of the entire disk roller, reducing the inlet width of the supermagnetic generator means reducing the number of disks, which in turn reduces the magnetic and water separation efficiency of the magnetic separation device. To ensure magnetic separation efficiency, each disk includes a disk skeleton, a mounting plate, and magnetic blocks embedded in the disk skeleton. The magnetic blocks have alternating N and S poles evenly distributed on the mounting plate.
[0013] In this scheme, compared with the existing disk structure, the disk is directly embedded on the mounting disc, reducing the need for traditional magnetic guide plates. At the same time, the magnetic blocks are evenly distributed with their poles touching, requiring fewer magnetic blocks. This also increases the magnetic field strength between the disks, the depth of action, and the magnetic field strength in the action space. This allows the processing capacity of the disk rollers to remain unchanged even with a reduction in the size and number of disks. Consequently, the inlet of the corresponding supermagnetic host can be reduced, and the requirement that the inlet width of the supermagnetic host be less than or equal to the outlet width of the flocculation tank can be guaranteed.
[0014] Preferably, in the disk roller, the magnetic blocks on two adjacent disks correspond to each other and have opposite magnetic poles, which can avoid the occurrence of zero magnetic field bands and ensure the adsorption effect of magnetic flocs on the disk.
[0015] Similarly, because excessive agitation in the flocculation tank can cause the water flowing into the magnetic separator to shift towards one side of the magnetic disk, resulting in uneven material distribution, a double-layer agitator can be installed in the flocculation tank to improve this situation. Double-layer agitation reduces the agitator speed while maintaining mixing efficiency, preventing excessive vortices in the flocculation tank, reducing wastewater shift at the outlet, and improving the problem of uneven material distribution in the effluent.
[0016] Preferably, the blade length of the double-layer agitator near the outlet of the flocculation tank is shorter than the blade length of the other layer.
[0017] In this design, the blades near the outlet of the flocculation tank are shorter and the stirring intensity is lower, further improving the issues of slanted effluent and uneven material distribution.
[0018] Preferably, a flow guide channel is provided between the outlet of the flocculation tank and the inlet of the supermagnetic host, and the flow guide plate is provided in the flow guide channel; a scum baffle is also provided at the inlet of the supermagnetic host.
[0019] In this scheme, when the outlet of the flocculation tank is set at the upper end of the flocculation tank, the coagulation equipment and the magnetic separation equipment can be connected through the guide channel. This makes installation more convenient. At the same time, the guide channel serves as a transition section, which facilitates the better guidance of the wastewater output from the flocculation tank by the guide plate. Meanwhile, the scum baffle can also prevent the light floating objects suspended in the wastewater from flowing into the super magnetic host, thereby affecting the adsorption effect of the disk.
[0020] The beneficial effects of this utility model are:
[0021] This invention limits the width of the inlet of the super magnetic host in the magnetic separation equipment, allowing the wastewater that is evenly distributed in the flocculation tank to enter the super magnetic host smoothly without causing turbulence due to the sudden widening of the flow channel. It also allows all the disks in the super magnetic host, including the two outermost disks, to process wastewater with similar magnetic floc density at the same time, ensuring disk utilization and improving the overall water purification efficiency of the magnetic separation equipment.

Detailed Implementation
[0028] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.
[0029] Example 1:
[0030] A magnetic separation wastewater treatment system, such as Figure 1 As shown, the device includes a flocculation device and a magnetic separation device. The flocculation device sequentially comprises a PAC reagent mixing tank, a magnetic media coagulation tank, and a PAM reagent flocculation tank 1. The magnetic separation device includes a supermagnetic generator 2. The outlet 101 of the flocculation tank is connected to the inlet 201 of the supermagnetic generator. The width of the inlet 201 of the supermagnetic generator is less than or equal to the width of the outlet 101 of the flocculation tank, preferably equal to it. The magnetic separation device also includes a disk roller 3 formed by multiple overlapping disks with uniform gaps.
[0031] Specifically, since the width of the inlet 201 of the super magnetic separator must be equal to the thickness of the entire disk roller 3, reducing the width of the inlet 201 means reducing the number of disks, and reducing the number of disks will reduce the magnetic and water separation efficiency of the magnetic separation device. To ensure magnetic separation efficiency, such as Figure 3 As shown, a single disk includes a disk skeleton 303, a mounting disc 302, and a magnetic block 301 embedded in the disk skeleton 303. The magnetic block 301 has N poles and S poles evenly distributed alternately on the mounting disc 302.
[0032] Furthermore, the magnetic blocks 301 on two adjacent disks correspond to each other and have opposite magnetic poles, which can avoid the occurrence of zero magnetic field bands and ensure the adsorption effect of magnetic flocs on the disk.
[0033] In this embodiment, compared to existing disk structures, the magnetic blocks are directly embedded in the disk frame 303, and the mounting circular plate 302 limits and fixes the magnetic blocks 301 on the disk frame 303, reducing the need for traditional magnetic guide plates. This results in a thinner disk compared to traditional disks. At the same time, the magnetic blocks 301 are evenly distributed with their poles touching, requiring fewer magnetic blocks 301. This also increases the magnetic field strength between disks, the depth of action, and the magnetic field strength in the action space. This allows the processing capacity of the disk roller 3 to remain unchanged even with a reduction in the size and number of disks. Consequently, the inlet 201 of the corresponding supermagnetic host can be reduced, and the width of the inlet 201 of the supermagnetic host can be less than or equal to the width of the outlet 101 of the flocculation tank.
[0034] By limiting the width of the inlet of the super magnetic host 2 in the magnetic separation equipment, the wastewater that is evenly distributed in the flocculation tank 1 can smoothly enter the super magnetic host 2 without causing turbulence due to the sudden widening of the flow channel. It also allows all the disks in the super magnetic host 2, including the two outermost disks, to process wastewater with similar magnetic floc density at the same time, ensuring the utilization rate of the disks and improving the overall water purification efficiency of the magnetic separation equipment.
[0035] Example 2:
[0036] In addition to ensuring that the wastewater entering the supermagnetic host 2 does not experience turbulence in Example 1, it is also necessary to ensure that the wastewater output from the flocculation equipment itself is uniformly distributed and flows stably. Figure 1 As shown, the width of the flocculation tank 1 is equal to the width of the outlet 101 of the flocculation tank. This ensures that the wastewater output from the flocculation tank 1 will not experience turbulence due to obstruction by the tank wall at the outlet 101, thus guaranteeing a uniform and stable water flow and ensuring the stability of the subsequent influent flow.
[0037] Since the flocculation tank 1 typically uses paddles to agitate and mix the water, excessive agitation can cause the water flowing into the magnetic separator to deflect towards the disks, thus reducing disk utilization. To mitigate this, a guide vane 102 is installed at the outlet 101 of the flocculation tank. The guide vane 102 guides the deflected water flow, ensuring that the wastewater output from the flocculation tank 1 flows directly into the super magnetic separator 2, allowing all disks to operate effectively.
[0038] Furthermore, such as Figure 1 As shown, the guide vanes 102 are evenly spaced, and the starting positions of the guide vanes 102 gradually move away from the flocculation device. The direction in which the guide vanes 102 move away is opposite to the deflection direction of the water effluent from the outlet 101 of the flocculation tank, ensuring that the water flow with an initial deflection direction can be evenly guided by the guide vanes.
[0039] Furthermore, the outlet 101 of the flocculation tank and the inlet 201 of the supermagnetic host can be directly bolted together, or a guide channel 4 can be provided between the outlet 101 of the flocculation tank and the inlet 201 of the supermagnetic host, with the guide plate 102 provided in the guide channel 4; a scum baffle 5 is also provided at the inlet 201 of the supermagnetic host.
[0040] When the outlet 101 of the flocculation tank is set at the upper end of the flocculation tank 1, the flocculation equipment and the magnetic separation equipment can be connected through the guide channel 4, which makes the installation more convenient. At the same time, the guide channel 4 serves as a transition section, which facilitates the better guidance of the sewage output from the flocculation tank 1 by the guide plate 102. Meanwhile, the scum baffle 5 can also prevent the light floating objects suspended in the sewage from flowing into the super magnetic host 2, thereby affecting the adsorption effect of the disk.
[0041] Example 3:
[0042] Similarly, because the wastewater in flocculation tank 1 may be excessively agitated, causing the water flowing into the magnetic separator to shift towards one side of the magnetic disk, resulting in uneven material distribution, a double-layer agitator 103 can be installed in the flocculation tank 1 to improve this situation. Through double-layer agitation, the rotational speed of the agitator can be reduced while ensuring mixing efficiency, preventing excessive vortex in the flocculation tank 1, reducing the wastewater shift at the outlet 101 of the flocculation tank, and improving the problem of uneven material distribution in the effluent.
[0043] Furthermore, in the double-layer stirring impeller 103, the blade length near the outlet 101 of the flocculation tank is shorter than the blade length of the other layer, such as... Figure 2 As shown, in this embodiment, the wastewater in the flocculation tank 1 flows from bottom to top. Therefore, the blades at the outlet 101 of the upper layer, which is closer to the flocculation tank, are shorter and have a smaller stirring amplitude; the blades at the inlet of the lower layer flocculation tank 1 are longer and have a larger stirring amplitude. Making the blades at the outlet 101 of the flocculation tank shorter and the stirring intensity lower further improves the situation of slanted water discharge and uneven material distribution.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
