Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a mobile container-type supermagnetic sewage treatment system. Background Art

[0002] With the rapid development of my country's economy and society, environmental and water pollution issues have become increasingly prominent. The treatment processes for wastewater like mine wastewater, black and odorous water, and industrial wastewater are more complex than those for domestic sewage. Rapid sedimentation of pollutants and efficient purification have been a long-standing challenge for the industry.

[0003] Traditional sewage treatment methods generally use fixed sewage treatment facilities, such as building huge physical sedimentation tanks. However, this treatment method has problems such as long construction period and high cost. In addition, fixed sewage treatment facilities have poor mobility, are not easy to move, and are less likely to be reused, which is not conducive to controlling treatment costs. In order to solve the problem of poor mobility of traditional fixed sewage treatment facilities, the integration of related facilities for sewage treatment in containers has gradually emerged, which can achieve rapid transfer of sewage treatment facilities and can be reused. However, due to the constraints of transportation conditions, the size of containers is generally limited, and the size of the box cannot be increased indefinitely as the demand for sewage treatment increases. Therefore, when it comes to sewage treatment in large water bodies, the processing efficiency of a single container is difficult to meet the treatment requirements.

[0004] Supermagnetic wastewater treatment technology generally involves adding reagents and magnetic seeds to wastewater to cause suspended solids to flocculate. A supermagnetic separator then separates the flocculates from the wastewater, achieving water purification. Our company has previously developed a containerized integrated magnetic flocculation system (CN112174421A) and a containerized integrated water treatment system (CN112225299A) based on this technology.

[0005] The former integrated magnetic flocculation equipment adds the reagent and magnetic seed separately to the reaction tank and stirs them with an agitator to fully mix the reagent, magnetic seed, and sewage. However, this stirring and mixing method will cause vortices in the reaction tank, which in turn cause the water flow out of the drain pipe to fluctuate. If the water flow is not uniform when it is subsequently sent to the super magnetic separator for solid-liquid separation, it will affect the super magnetic separator's separation of magnetic flocs. Moreover, because the magnetic flocs with magnetic seeds are heavier, the uneven flow of water in the drain pipe can cause the magnetic flocs to accumulate in the pipe, thereby affecting the liquid flow in the drain pipe and even clogging the pipe in severe cases.

[0006] The sewage inlet of the super magnetic separator of the latter integrated water treatment equipment is mainly located in the middle position of the equipment. This will cause the sewage to flow mainly through the middle position of the disk assembly when flowing in the super magnetic separator. This will cause the disk in the middle position to absorb more magnetic flocs, while the disks at the two end positions will absorb fewer magnetic flocs, which will affect the super magnetic separator's separation efficiency of magnetic flocs and result in low sewage treatment efficiency.

[0007] Therefore, in view of the above-mentioned technical problems, it is necessary to make new innovations. Summary of the Invention

[0018] Compared with the prior art, the mobile container-type supermagnetic sewage treatment system of the present application has at least one or more of the following beneficial effects:

[0019] (1) The mobile containerized supermagnetic sewage treatment system of the present application, by placing the sewage treatment facilities in two vehicle-mountable containers, not only achieves the purpose of convenient transfer by car, greatly improves the mobility of the sewage treatment facilities, but also can meet the sewage treatment needs of large water bodies; at the same time, the use of supermagnetic separation technology can also effectively improve the efficiency of sewage treatment;

[0020] (2) The mobile container-type super-magnetic sewage treatment system of the present application is connected to each other through a flat water distribution device, and a vortex-stopping and slow-flow device is provided at the outlet of the sewage stirring device. The vortex-stopping and slow-flow device can reduce the vortex of the water flow in the sewage stirring device, so that it can smoothly enter the water distribution device. The water distribution device is provided with multiple water dividing baffles, which can further enable the water flow to enter the super-magnetic separation device more evenly, thereby ensuring that the sewage can flow evenly through each magnetic disk when circulating in the super-magnetic separation device, effectively solving the problem of uneven water flow into the super-magnetic separation device due to vortex, greatly improving the subsequent super-magnetic separation device's sewage treatment efficiency and effect, and at the same time, the uniform flow of water through the water distribution device can also prevent the magnetic flocs in the sewage from generating a large amount of deposition in the water distribution device, thereby effectively extending the cleaning cycle of the water distribution device;

[0021] (3) The mobile container-type supermagnetic sewage treatment system of the present application has an anti-vortex and slow-flow device that can be connected to the sewage stirring device through a rod-shaped adjustment device, so that the height of the anti-vortex and slow-flow device and the distance from the outlet position can be adjusted according to the water flow and water quality.

[0022] (4) The mobile container-type super magnetic sewage treatment system of the present application has a water distribution device that is less than 2 meters long, and the end connected to the super magnetic separation device is tilted downward by 0 to 15 degrees. The reasonable length design and tilt angle design allow the sewage in the sewage stirring device to pass smoothly through the water distribution device, thereby reducing the possibility of magnetic flocs being deposited in the water distribution device, and at the same time, it does not cause the water flow rate to be too fast and cause damage to the magnetic flocs;

[0023] (5) The mobile container-type super magnetic sewage treatment system of the present application has a sediment detection device provided near the water outlet of its water distribution device, which can detect the sediment in the water distribution device. When the sediment in the water distribution device reaches a certain amount, the sediment detection device can send a detection signal to the system control box, so that the system can promptly alarm to remind the user that the water distribution device needs to be cleaned or unblocked, thereby effectively avoiding the normal operation of the entire super magnetic sewage treatment system due to partial blockage or complete blockage in the water distribution device;

[0024] (6) The mobile container-type super-magnetic sewage treatment system of the present application has a detachable connection between the water distribution device and the outlet of the last sewage stirring device and the water inlet of the super-magnetic separation device through a flange structure. This is not only convenient for assembly, but also allows users to more conveniently disassemble and clean the water distribution device during later use;

[0025] (7) The mobile container-type super magnetic sewage treatment system of the present application has a water distribution device that can be designed with a portion of the section as a flexible section, which can ensure that the water distribution device can be easily installed even when there is a certain error between the installation positions of the two containers. In addition, during subsequent use, it can also effectively avoid problems such as deformation or even breakage of the water distribution device caused by different amplitudes of settlement between the two containers;

[0026] (8) The mobile container-type super magnetic sewage treatment system of the present application provides a support frame in the mixing box to support the bottom of the sewage stirring paddle, thereby ensuring that the sewage stirring paddle rotates more stably and improving the stability of the entire equipment operation; at the same time, it can also reduce the force borne by the sewage stirring drive device and its fixed bracket, thereby extending the service life;

[0027] (9) The mobile container-type super magnetic sewage treatment system of the present application is connected in sequence through drainage holes arranged diagonally at different heights, and the addition positions of each agent and magnetic seed are all far away from the drainage of the corresponding sewage stirring device, thereby greatly improving the stirring and mixing time between the agent and magnetic seed and the sewage, and thus effectively improving the flocculation effect of the agent and magnetic seed on the sewage; the sewage stirring device is designed with a funnel component so that the added agent can be added to the position near the bottom of the sewage stirring device, and the user can also intuitively observe whether there is still agent being added to the corresponding sewage stirring device, so that the user can replenish the agent in time;

[0028] (10) The mobile container-type super magnetic sewage treatment system of the present application has two coagulant dosing ports on the stirring device and a flow valve. The operator can set the optimal coagulant flow ratio by adjusting the flow of the two flow valves, thereby improving the flocculation effect on the sewage;

[0029] (11) The mobile container-type super magnetic sewage treatment system of the present application, by providing a hood component on the top of the container to replace the traditional wall exhaust fan, can achieve exhaust from the interior of the container even without electric drive; at the same time, it can also prevent the interior of the container from overheating due to sun exposure and other reasons when the equipment is not in operation, thereby preventing damage to the equipment; at the same time, the hood component can be raised to effectively improve the exhaust effect of the hood component;

[0030] (12) The mobile container-type super magnetic sewage treatment system of the present application uses a variable frequency water pump to replenish water to each reagent preparation device. Compared with the traditional ordinary water pump water supply, it can realize intelligent control of water replenishment, and does not require the water supply pump to be in a normally open state. While saving electricity, it also does not need to set up a reflux, saving energy consumption. At the same time, the operator no longer needs to manually start and stop the water supply pump, and the water replenishment operation is more convenient; at the same time, the water purified by the super magnetic separation device is pumped to each reagent preparation device for reagent configuration, which can realize the reuse of treated water and save water resources.

DETAILED DESCRIPTION

[0045] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0046] Example

[0047] The present invention provides a mobile container-based supermagnetic sewage treatment system, comprising a first container 100, a second container 200, and a water distribution device 300 connecting the two containers. The width of each of the first container 100 and the second container 200 is no more than 3 meters, and the length of each of the first container 100 and the second container 200 is 6-15 meters, respectively, to accommodate the market requirement of 17.5-meter flatbed trucks for transportation. The height of each of the first container 100 and the second container 200 is no more than 3 meters, ensuring that the vehicle carrying the containers does not exceed the height. Preferably, the width and height of each of the first container 100 and the second container 200 are both 3 meters, and the length is 12 meters.

[0048] The first container 100 is provided with a plurality of sewage stirring devices, and preferably at least three sewage stirring devices are provided. The sewage stirring device is provided near one end of the first container 100, such as Figures 1 to 4 As shown. Multiple sewage stirring devices are connected in sequence. The sewage stirring device includes a stirring box and a sewage stirring paddle 114. The stirring box is a box structure with an opening at the upper end. The sewage stirring paddle 114 is arranged in the stirring box, and the sewage stirring paddle 114 can be driven by the sewage stirring driving device 115 to rotate in the stirring box. It should be noted that, Figures 1 to 4 What is shown is that the mixing box of the sewage mixing device is obtained by dividing it with a partition in the first container 100, but in actual implementation, an independent box structure can also be set in the first container 100 as the box structure of each sewage mixing device as needed, and the material of the mixing box is preferably carbon steel.

[0049] In a further embodiment, the sewage stirring drive device 115 is arranged at the upper end of the stirring box through a fixing bracket 116, and the upper end of the sewage stirring paddle 114 is connected to the driving shaft of the sewage stirring drive device 115, as shown in FIG. Figure 4As shown. A support frame 117 is provided at the bottom of the mixing box corresponding to the sewage stirring paddle 114. The lower end of the sewage stirring paddle 114 is rotatably connected to the support frame 117. The lower end of the sewage stirring paddle 114 is preferably rotatably connected to the support frame 117 via a nylon sleeve 1171. In a specific implementation, water is present in the mixing box, and the water can provide a certain lubrication effect when the sewage stirring paddle 114 rotates, thereby reducing the friction between the sewage stirring paddle 114 and the nylon sleeve 1171, thereby allowing the lower end of the sewage stirring paddle 114 to rotate smoothly within the nylon sleeve 1171. In the specific implementation, in order to stir more sewage, the stirring box will be designed to be relatively high, so the length of the sewage stirring paddle 114 will also be very long. By arranging a support frame 117 at the bottom of the stirring box cavity, the sewage stirring paddle 114 can be ensured to rotate more stably, thereby improving the stability of the operation of the entire equipment; at the same time, it can also reduce the force borne by the fixed bracket 116 and the sewage stirring drive device 115, thereby extending the service life.

[0050] The first container 100 is also provided with a coagulant preparation device 120 and a coagulant preparation device 130. The coagulant preparation device 120 is configured to prepare a coagulant, and the coagulant preparation device 130 is configured to prepare a coagulant. The working principle of the coagulant preparation device 120 and the coagulant preparation device 130 is mainly to add the pharmaceutical raw materials to be prepared into a container, and then add water into the container and stir and mix, so as to obtain the pharmaceutical agent to be prepared. In this application, the coagulant preparation device 120 and the coagulant preparation device 130 are conventional equipment and are not the focus of protection of this application. Therefore, the specific structure of the coagulant preparation device 120 and the coagulant preparation device 130 will not be described in detail in this embodiment. Preferably, the coagulant used in the supermagnetic sewage treatment system of this embodiment is a PAC agent, and the coagulant aid is an anionic PAM agent. In practice, the operator can add the PAC raw material to the coagulant preparation device 120, then add water to the coagulant preparation device 120 in the desired ratio and stir to dilute the mixture, thereby obtaining a PAC agent of appropriate concentration, i.e., a coagulant. Similarly, the operator can add the anionic PAM raw material to the coagulant aid preparation device 130, then add water to the coagulant aid preparation device 130 in the desired ratio and stir to dilute the mixture, thereby obtaining an anionic PAM agent of appropriate concentration, i.e., a coagulant aid.

[0051] The coagulant preparation device 120 and the coagulant aid preparation device 130 are respectively arranged near the other end of the first container 100. Figure 2 and Figure 3As shown. The coagulant preparation device 120 and the coagulant preparation aid device 130 are respectively arranged near the side walls of the first container 100. Preferably, the coagulant preparation device 120 is arranged near one side wall of the first container 100, and the coagulant preparation aid device 130 is arranged near the other side wall of the first container 100, so that an operating space is formed in the middle of the first container 100, which is defined as the first operating space. In a specific implementation, the end side of the first container 100 where the coagulant preparation device 120 and the coagulant preparation aid device 130 are arranged can serve as the first entrance and exit of the first container 100, and the operator can enter the first operating space through the first entrance and exit to operate the coagulant preparation device 120 or the coagulant preparation aid device 130.

[0052] In a further embodiment, three sewage stirring devices are preferably provided in the first container 100, which are defined as a first sewage stirring device 111, a second sewage stirring device 112 and a third sewage stirring device 113. The first sewage stirring device 111, the second sewage stirring device 112 and the third sewage stirring device 113 are sequentially distributed along the length direction of the first container 100, and the third sewage stirring device 113 is provided near one end of the first container 100. Figures 1 to 4 As shown. The mixing box of the first sewage mixing device 111 is defined as the first mixing box 1111, the mixing box of the second sewage mixing device 112 is defined as the second mixing box 1121, and the mixing box of the third sewage mixing device 113 is defined as the third mixing box 1131. The three mixing boxes are connected in sequence through the drainage holes 1122 arranged diagonally at different heights. For example Figure 5 As shown in the figure, the first stirring box 1111 and the second stirring box 1121 are connected near the top position on the left side, and the second stirring box 1121 and the third stirring box 1131 are connected near the bottom position on the right side. In a specific implementation, the untreated sewage enters the first stirring box 1111 near the bottom position of the first stirring box 1111. For example, the sewage pipe 910 can extend from the upper end of the first stirring box 1111 into the first stirring box 1111, and the pipe mouth of the sewage pipe 910 is close to the bottom of the first stirring box 1111, so that the untreated sewage discharged from the sewage pipe 910 can enter the first stirring box 1111 from the bottom position of the first stirring box 1111. The outlet 1133 of the third stirring box 1131 is set on the left side near the top position. The above design can extend the flow distance of sewage in the corresponding mixing box as much as possible, so that the sewage stirring paddle 114 can stir the sewage for a longer time, so that the sewage and the reagent or magnetic seed in the mixing box can be mixed more evenly, thereby improving the purification effect of sewage.

[0053] Due to the stirring action of the sewage stirring paddle 114, the sewage in the third stirring box 1131 will form a vortex, and the vortex will cause the water flow out of the third stirring box 1131 to fluctuate, which will cause the subsequent water flow into the super magnetic separation device 210 to be uneven, thereby affecting the subsequent super magnetic separation device 210's sewage treatment efficiency and effect. Moreover, if the water flow through the pipeline fluctuates, it will increase the possibility of magnetic flocs in the sewage settling, which will cause a large amount of sediment to accumulate in the pipeline and cause pipeline blockage. Therefore, in the present application, a vortex-stopping and flow-slowing device 1132 is also provided at the outlet 1133 of the third stirring box 1131, such as Figure 4 or Figure 5 In the schematic diagram shown in the figure, the vortex-stopping and flow-reducing device 1132 can be a vertically arranged stainless steel plate structure, and is spaced apart from the side wall of the third mixing box 1131 where the outlet 1133 is provided. The two ends of the vortex-stopping and flow-reducing device 1132 are respectively fixed to the inner wall of the third mixing box 1131, for example, by welding. Of course, the connection method between the vortex-stopping and flow-reducing device 1132 and the third mixing box 1131 is not limited to this. For example, the vortex-stopping and flow-reducing device 1132 can also be fixedly connected to the side wall of the third mixing box 1131 where the outlet 1133 is provided by welding a support rod. For another example, the vortex-stopping and flow-reducing device 1132 can also be connected to the third mixing box 1131 through an adjustment device, and the adjustment device can be, for example, a slide rail, so that the user can adjust the height of the vortex-stopping and flow-reducing device 1132 or the distance from the outlet 1133 according to the water flow and water quality. The upper end of the anti-swirl and slow-flow device 1132 is higher than the upper edge of the outlet 1133, while the lower end is lower than the lower edge of the outlet 1133, thereby blocking the outlet 1133. Figure 6 and Figure 7 As shown. The water flow can enter the gap formed between the vortex-stopping and flow-slowing device 1132 and the third mixing box 1131 through the lower end of the vortex-stopping and flow-slowing device 1132, and then flow out from the outlet 1133, thereby effectively solving the problem of the water flow out of the third mixing box 1131 being fluctuating due to the vortex.

[0054] In a further embodiment, the coagulant prepared by the coagulant preparation device 120 is sucked and added to a position near the bottom of the first stirring tank 1111 by a suction pump, such as a metering pump. This suction pump is defined as a first suction pump 410. Specifically, the suction port of the first suction pump 410 is connected to the preparation chamber of the coagulant preparation device 120, and the first discharge port of the first suction pump 410 is connected to a first pipe 510. The first pipe 510 extends to the top of the first stirring tank 1111 and is provided with a first nozzle 511 at the first stirring tank 1111. When the first suction pump 410 is in operation, it sucks the coagulant in the preparation chamber of the coagulant preparation device 120 into the first pipe 510, and the sucked coagulant flows into the first stirring tank 1111 through the first nozzle 511. A funnel component 118 is provided in the first mixing box 1111 at the position corresponding to the first pipe opening 511, which is defined as the first funnel component. Figure 3 As shown. The bottom opening of the first funnel component extends downward and is close to the bottom of the first stirring box 1111. In this way, under the guidance of the first funnel component, the coagulant flowing out of the first pipe opening 511 can be added to the bottom of the first stirring box 1111, so that the coagulant addition position can be kept away from the drain port 1122 of the first stirring box 1111, preventing the coagulant from flowing out into the second stirring box 1121 as soon as it is added to the first stirring box 1111. This greatly increases the mixing time of the coagulant and sewage, thereby effectively improving the sewage treatment effect of the coagulant.

[0055] The coagulant prepared by the coagulant preparation device 130 is also sucked by a suction pump such as a metering pump and added to a position near the top of the second stirring box 1121 and a position near the bottom of the third stirring box 1131. This suction pump is defined as a second suction pump 420. Specifically, the suction port of the second suction pump 420 is connected to the preparation chamber of the coagulant preparation device 130, and the second discharge port of the second suction pump 420 is connected to the second pipe 520. The second pipe 520 extends to the top of the second stirring box 1121 and the third stirring box 1131, and the second pipe 520 is provided with a second pipe opening 521 corresponding to the second stirring box 1121 and a third pipe opening 522 corresponding to the third stirring box 1131. When the second suction pump 420 is working, it will suck the coagulant in the preparation chamber of the coagulant preparation device 130 into the second pipe 520, and the sucked coagulant flows into the second stirring box 1121 through the second pipe opening 521, and flows into the third stirring box 1131 through the third pipe opening 522. Similarly, another funnel component 118 is also provided in the third stirring box 1131 corresponding to the third pipe opening 522, which is defined as the second funnel component, so that the coagulant flowing out of the third pipe opening 522 is added to the bottom of the third stirring box 1131. Similarly, the connection between the above stirring boxes through the diagonally staggered drainage holes 1122 also makes the coagulant addition position away from the outlet of the corresponding stirring box, thereby greatly increasing the mixing time of the coagulant and sewage, thereby effectively improving the sewage treatment effect of the coagulant.

[0056] During the specific implementation, it is also necessary to add magnetic seeds into the second stirring box 1121. By stirring the sewage with coagulant, magnetic seeds and coagulant aid in sequence under the action of three sewage stirring devices, the suspended matter in the sewage will form magnetic flocs, and then flow out from the outlet 1131 of the third stirring box 1131.

[0057] In a further embodiment, valve components may be provided on the second pipe opening 521 and the third pipe opening 522, respectively. Figure 3 As shown, the valve component is defined as a flow valve 523. By adjusting the flow valve 523, the flow rate of the coagulant at the second pipe opening 521 or the third pipe opening 522 can be adjusted. In practice, the operator can improve the flocculation effect on the sewage by adjusting the flow rate ratio of the coagulant at the two pipe openings.

[0058] It should be noted that, in a specific implementation, the coagulant preparation device 120 is preferably provided in two groups. Thus, while the agent in one group is being pumped and added to the corresponding sewage agitation device, the other group can continue to prepare new agents. This not only saves agent preparation time and improves sewage treatment efficiency, but also serves as a backup. If one group of devices fails, it will not cause the entire super magnetic sewage treatment system to cease operation. Furthermore, by providing the funnel component 118, the user can also visually observe whether the agent is still being added to the corresponding mixing box, thereby facilitating timely replenishment of the agent.

[0059] The second container 200 is provided with a super magnetic separation device 210 and a magnetic seed recovery device 220. The super magnetic separation device 210 is provided near one end of the second container 200. Figure 8 shown.

[0060] The super magnetic separation device 210 includes a main body box 211 and a magnetic disk assembly, a scraping bar assembly, a slag planing bar assembly and an auger conveying device 219 arranged in the main body box 211. Figure 9 The disk assembly includes a main shaft 212 and a plurality of disks 213 arranged on the main shaft 212 in parallel and spaced apart. Figure 10 As shown. The main shaft 212 is rotatably arranged in the main housing 211, and the axial direction of the main shaft 212 is consistent with the length direction of the second container 200, that is, the disk assembly in the super magnetic separation device 210 rotates toward the water distribution device 300. In order to ensure that the water flow can pass evenly and smoothly between the disks 213, the water inlet of the super magnetic separation device 210 is preferably designed as a long hole, and the length direction is consistent with the axial direction of the main shaft 212, and is arranged on one side of the main housing 211 in the radial direction of the main shaft 212, as shown. Figure 9 In specific implementation, the water inlet of the super magnetic separation device 210 is set through the second container 200, as shown. Figure 8As shown. The placement of the super magnetic separation device 210 in this way can make it easier for the water inlet of the main box 211 to pass through the container without the need to connect a longer pipe. On the one hand, this can avoid the risk of blocking the pipe due to the heavier medium after adding the magnetic seed, as well as the increased cost caused by strengthening the pipe strength. On the other hand, it also saves the space occupied by the pipe and improves the space utilization rate inside the container. In specific implementation, the two containers are preferably placed in parallel. The position of the outlet 1133 and the water inlet of the super magnetic separation device 210 corresponds and is relatively arranged. The outlet 1133 and the water inlet of the super magnetic separation device 210 are connected through a uniform water distribution device 300. The uniform water distribution device 300 is a flat hollow square pipe, the width direction of which is consistent with the axial direction of the main shaft 212, and the cross-sectional size is preferably consistent with the size of the inlet of the super magnetic separation device 210, that is, the water outlet of the uniform water distribution device 300 is matched with the water inlet of the super magnetic separation device 210. The two ends of the water distribution device 300 are respectively fixedly connected to the outlet 1133 and the water inlet of the super magnetic separation device 210. Specifically, the two ends of the water distribution device 300 and the outlet 1133 and the water inlet of the super magnetic separation device 210 can be designed as matching flange structures, and then the two ends of the water distribution device 300 are respectively connected to the outlet 1133 and the water inlet of the super magnetic separation device 210 through the flange structure with bolts and other fasteners to achieve detachable fixed connection, such as Figure 1 、 Figure 11 and Figure 12As shown, this is not only convenient for assembly, but also allows the user to disassemble and clean the water distribution device 300 more conveniently during later use. Of course, in order to ensure sealing, sealing members 360 such as sealing gaskets can be provided at the joints of the flange structures. The length of the water distribution device 300 is less than 2 meters, and the outlet end of the water distribution device 300 is tilted downward by 0 to 15 degrees. Within this length and tilt angle range, it can ensure that the sewage from the third stirring box 1131 can pass through the water distribution device 300 smoothly, thereby reducing the possibility of magnetic flocs being deposited in the water distribution device 300, and at the same time, it will not cause the water flow rate to be too fast to damage the magnetic flocs. Furthermore, a sediment detection device 320 can be provided near the outlet of the water distribution device 300 to detect the sediment in the water distribution device 300. When the sediment in the water distribution device 300 reaches a certain amount, the sediment detection device 320 can send a detection signal to the following electrical control box 800 of the system, so that the system can promptly alarm to remind the user that the water distribution device 300 needs to be cleaned or unblocked, thereby effectively avoiding the normal operation of the entire super magnetic sewage treatment system due to partial blockage or complete blockage in the water distribution device 300. The sediment detection device 320 can be, for example, a proximity switch, etc., provided on the side wall of the water distribution device 300, such as Figure 11 In the water distribution device 300, a plurality of water dividing plates 310 are arranged along the water flow direction, that is, the plurality of water dividing plates 310 are arranged at intervals along the width direction of the water distribution device 300, as shown. Figure 11 and Figure 12 As shown, the water flow can be further made to enter the super magnetic separation device 210 more evenly, thereby ensuring that the sewage can flow evenly through each magnetic disk 213 when circulating in the super magnetic separation device 210, effectively solving the problem of uneven water flow into the super magnetic separation device 210 due to eddy currents, greatly improving the subsequent super magnetic separation device 210's sewage treatment efficiency and effect, and at the same time, the water flow evenly flowing through the water distribution device 300 can also prevent the magnetic flocs in the sewage from forming a large amount of sedimentation in the water distribution device 300, thereby effectively extending the cleaning cycle of the water distribution device 300. It should be noted that, Figure 11 and Figure 12The water distribution device 300 shown in the figure is a preferred embodiment, comprising a first rigid section 330, a flexible section 340, and a second rigid section 350 connected in sequence. The first rigid section 330 is connected to the outlet 1133, and the second rigid section 350 is connected to the water inlet of the supermagnetic separation device 210. The flexible section 340 can be made of a soft material such as rubber. It can be designed with rigid rings made of a rigid material such as steel molded at both ends to form a flange structure. The first and second rigid sections 330 and 350 can also be designed with flange structures at both ends, so that the ends of the flexible section 340 are fixedly connected to the first and second rigid sections 330 and 350 via the flange structures and fasteners such as bolts. To ensure sealing, sealing members 360 such as gaskets can also be provided between the flange structures of each section. The water-dividing baffle 310 can also be provided only within the first and second rigid sections 330 and 350. The water distribution device 300 is designed with a section as a flexible section 340, which can ensure that the water distribution device 300 can be installed well and conveniently even when there is a certain error between the installation positions of the two containers. In the subsequent use process, it can also effectively avoid deformation or even breakage of the water distribution device 300 due to different amplitudes of settlement between the two containers.

[0061] The main shaft 212 can be driven to rotate within the main housing 211 by a main shaft drive device 214. The main shaft drive device 214 preferably employs a motor that can drive the main shaft 212 via a gear transmission. The rotation of the main shaft 212 drives the magnetic disk 213 to rotate, thereby attracting magnetic flocs in the wastewater and separating them from the wastewater. The magnetic flocs form residue on the magnetic disk 213. The wastewater purified by the magnetic disk 213 becomes clear and is then discharged from the outlet of the main housing 211. The scraper bar assembly includes a plurality of scraper bars 215, each of which has a residue collection groove formed therein. The scraper bars 215 are located on both sides of the magnetic disk 213. Specifically, a crossbar 216 can be provided within the main housing 211, the length of which aligns with the axis of the main shaft 212. One end of the scraper bar 215 is fixed to the crossbar 216, while the other end extends toward the main shaft 212. The scraper bar 215 has a V-shaped cross-section with its opening facing upward, forming a strip-shaped slag collecting groove at the upper end of the scraper bar 215. The side wings of the scraper bar 215 fit tightly against the corresponding magnetic disk 213. As the magnetic disk 213 rotates, the scraper bar 215 scrapes the slag adsorbed on the magnetic disk 213 into the slag collecting groove.

[0062] The slag strip assembly includes a slag strip roller 217 and a plurality of slag strip bars 218 mounted on the slag strip roller 217. The axis of the slag strip roller 217 aligns with the axis of the main shaft 212. The slag strip bars 218 are divided into several groups, each group comprising several slag strip bars 218 disposed around the slag strip roller 217. Specifically, the slag strip bars 218 are strip-shaped structures, one end of which is fixedly connected to the slag strip roller 217, and the other end of which extends away from the slag strip bars 218. Each group of slag strip bars 218 corresponds to one of the scraper bars 215. When the slag strip roller 217 is driven by a slag strip drive device, the extended end of the slag strip bar 218 extends into the corresponding slag trough and scrapes the slag material therein to the auger conveyor device 219. The slag strip drive device is preferably a motor, which can drive the slag strip roller 217 through gear transmission, chain drive, or belt drive. The auger conveyor 219 transports the slag to the slag outlet 2111 of the supermagnetic separation device 210, which is in communication with the magnetic seed recovery device 220. Preferably, the slag outlet 2111 of the supermagnetic separation device 210 and the magnetic seed recovery device 220 are connected via a steel hose. Because the slag transported by the auger conveyor 219 is relatively dry, a water outlet can be provided at the slag outlet 2111 of the supermagnetic separation device 210 to dilute the slag in the steel hose by connecting a water pipe, thereby ensuring that the slag can flow smoothly to the magnetic seed recovery device 220.

[0063] The magnetic seed recovery device 220 includes a high-speed shearing device 221 and a magnetic seed separation device 222. Figure 8 and Figure 13As shown. The high-speed shearing device 221 includes a shearing box 2211 and a shearing paddle 2212 disposed within the shearing box 2211. The shearing box 2211 is in communication with the slag outlet 2111. The shearing paddle 2212 can be driven by a shearing drive 2213 to rotate at high speed within the shearing box 2211. The shearing drive 2213 preferably utilizes a high-speed motor. By driving the shearing paddle 2212 to rotate at high speed, the slag conveyed into the shearing box 2211 can be deflocculated into magnetic seed and sludge. The magnetic seed separation device 222 includes a separation box 2221, a magnetic drum 2224 disposed within the separation box 2221, and a magnetic seed stirring paddle 2226. The separation box 2221 is provided with a communicating separation chamber 2222 and a stirring chamber 2223. The magnetic drum 2224 is disposed within the separation chamber 2222, and the stirring chamber 2223 is located on one side of the magnetic drum 2224 in a radial direction. The magnetic drum 2224 can be driven by a magnetic drum driving device 2225 to rotate within the separation chamber 2222, and the upper end of the magnetic drum 2224 rotates toward the direction where the stirring chamber 2223 is provided. The magnetic drum driving device 2225 is preferably a motor, and can drive the magnetic drum 2224 to rotate by gear transmission, chain transmission, or belt transmission.

[0064] A scraper 2227 is provided on one side of the magnetic drum 2224 facing the stirring chamber 2223. One end of the scraper 2227 contacts the magnetic drum 2224, and the other end of the scraper 2227 extends obliquely downward to the stirring chamber 2223. Figure 13As shown. The separation chamber 2222 is connected to the shear box 2211. Through the rotation of the magnetic drum 2224, the magnetic seeds transported to the separation chamber 2222 will be adsorbed on the surface of the magnetic drum 2224, thereby achieving magnetic seed separation. As the magnetic drum 2224 continues to rotate, the scraper 2227 will scrape the magnetic seeds adsorbed on the magnetic drum 2224 into the stirring chamber 2223. By passing water into the stirring chamber 2223, the magnetic seeds can be diluted to obtain a magnetic seed mixture. The magnetic seed stirring paddle 2226 is arranged in the stirring chamber 2223, and the magnetic seed stirring paddle 2226 can be driven by the magnetic seed stirring drive device 2228 to rotate in the stirring chamber 2223. The magnetic seed stirring drive device 2228 preferably adopts a motor, which is arranged at the upper end of the stirring chamber 2223, and the upper end of the magnetic seed stirring paddle 2226 is fixedly connected to the rotating shaft of the magnetic seed stirring drive device 2228. The magnetic seed stirring drive device 2228 works and drives the magnetic seed stirring paddle 2226 to rotate, thereby stirring the magnetic seed mixture in the stirring chamber 2223, so that the magnetic seeds in the magnetic seed mixture are more evenly dispersed. Afterwards, the magnetic seed mixture in the stirring chamber 2223 can be sucked and added to the second stirring box 1121 through the magnetic seed suction pump 440 and the magnetic supplement tube 940, thereby realizing the recycling of the magnetic seeds and saving costs. The sludge in the separation chamber 2222 can be sucked to a designated position by a suction pump, and the suction pump is defined as the first sludge suction pump.

[0065] In a further embodiment, a storage device can also be provided to store the sludge generated after the magnetic seed recovery device 220 separates the magnetic seeds. The storage device is connected to the sewage outlet of the magnetic seed recovery device 220. For example, the suction port of the first sludge suction pump can be connected to the sewage outlet of the magnetic seed recovery device 220 through the sewage pipe 950, and the discharge port of the first sludge suction pump can be connected to the storage device, and then the sludge in the separation chamber 2222 can be sucked and added to the storage device for storage through the first sludge suction pump. It should be noted that the storage device can be designed according to customer needs. For example, it can be a pit or pool set up at the sewage treatment site, or it can be a box structure integrated on the second container 200.

[0066] In a further embodiment, a sludge conditioner preparation device 230 and a sludge dewatering device 240 may also be provided within the second container 200. The sludge conditioner preparation device 230 is configured to prepare sludge conditioner. The operating principle of the sludge conditioner preparation device 230 is substantially the same as that of the coagulant preparation device 120 or the coagulant aid preparation device 130, and will not be further described herein. Preferably, the sludge conditioner employed in the supermagnetic sewage treatment system of this embodiment is a cationic PAM agent. In a specific implementation, the operator may add cationic PAM raw materials to the sludge conditioner preparation, then add water to the sludge conditioner preparation according to the desired proportion and stir to dilute the mixture, thereby obtaining a cationic PAM agent of the appropriate concentration, i.e., the sludge conditioner. The sludge conditioner is pumped into the sludge dewatering device 240 via a suction pump, which is defined as the third suction pump 430. The sludge in the storage device is then pumped through the sludge pipe 960 by a suction pump and added to the sludge dewatering device 240. This suction pump is defined as the second sludge suction pump. The sludge dewatering device 240 then dewaters the added sludge. The sludge dewatering device 240 is preferably a screw stacker and is located near the end of the second container 200 away from the supermagnetic separation device 210. The sludge conditioning agent preparation device 230 and the sludge dewatering device 240 are each located near a side wall of the second container 200. Preferably, the sludge conditioning agent preparation device 230 is located near one side wall of the second container 200, while the sludge dewatering device 240 is located near the other side wall of the second container 200. This creates an operating space within the second container 200, defined as the second operating space. In practice, the end of the second container 200 where the sludge dewatering device 240 is located serves as an entrance and exit to the second container 200, defined as the second entrance and exit. The operator can enter the second operating space through the second entrance and exit to operate the sludge conditioner preparation device 230 and the sludge dewatering device 240. The sludge dewatering device 240 is located near the second entrance and exit. After the sludge is dewatered by the sludge dewatering device 240, the operator can more conveniently transport the dewatered sludge.

[0067] Furthermore, since both PAC and PAM agents are volatile, and PAC in particular can corrode other equipment within the container, such as motors, the agents within the coagulant preparation device 120, the coagulant aid preparation device 130, and the sludge conditioner preparation device 230 must be promptly drained when not in use for extended periods. In practice, each of the coagulant preparation device 120, the coagulant aid preparation device 130, and the sludge conditioner preparation device 230 can be equipped with a drain pipe 920 connected to the bottom of its respective stirring chamber and sealed with a valve component, designated as a drain valve 921. When draining is required, simply open the corresponding drain valve 921. However, during daily use, operators may forget to drain, resulting in corrosion of other equipment within the container. Furthermore, during use, the agents may also volatilize. If not promptly drained, this can also corrode the container's equipment over time. Therefore, an exhaust system is necessary for the container. The traditional method is to use a wall exhaust fan, that is, to install an exhaust fan on the side wall of the container. However, this exhaust method requires electricity to drive, so if the equipment is not in operation, the exhaust fan will also stop working. If the operator forgets to empty the reagents in the coagulant preparation device 120, the coagulant aid preparation device 130, or the sludge conditioning agent preparation device 230, the volatilized reagents cannot be discharged in time. In this application, by installing a hood component 700 on the top of the first container 100 and / or the top of the second container 200 to replace the traditional wall exhaust fan, it is possible to exhaust the container interior even without electricity. At the same time, it can also prevent the container interior from overheating due to sun exposure and other reasons when the equipment is not in operation, which may cause damage to the equipment. Furthermore, the hood component 700 can be connected to the container via a pipe extension 710 to increase the installation height of the hood component 700, thereby effectively improving the exhaust efficiency of the hood component 700.

[0068] In a further embodiment, the present application preferably uses a variable frequency water pump 600 to replenish water to the coagulant preparation device 120, the coagulant aid preparation device 130, the sludge conditioner preparation device 230, or the sludge dewatering device 240. It is further preferred to use two variable frequency water pumps 600 arranged in parallel, so that even if one of the variable frequency water pumps 600 fails, the normal operation of the entire super magnetic sewage treatment system will not be affected. The suction port of the variable frequency water pump 600 is connected to the main housing 211 of the super magnetic separation device 210. In this way, the variable frequency water pump 600 can re-suction the purified water obtained after separating the magnetic flocs in the super magnetic separation device 210 to the coagulant preparation device 120, the coagulant aid preparation device 130, or the sludge conditioner preparation device 230 for use in preparing reagents, or to the sludge dewatering device 240 for flushing, thereby achieving the reuse of treated water and saving water resources. By providing a variable frequency water pump 600, when water needs to be replenished to the coagulant preparation device 120, the coagulant aid preparation device 130, the sludge conditioning agent preparation device 230, or the sludge dewatering device 240, once the corresponding water replenishment valve 931 is opened, the pressure in the water replenishment pipe 930 will decrease, and the variable frequency water pump 600 will automatically start after detecting the pressure change. When the water replenishment is completed and the corresponding water replenishment valve 931 is closed, the pressure in the water replenishment pipe 930 will increase, and the variable frequency water pump 600 will automatically shut down after detecting that the pressure has increased to a set value. Compared with traditional ordinary water pump water supply, this achieves intelligent water replenishment control, does not require the water supply pump to be in a constantly open state, saves electricity, and does not require a backflow setting, saving energy. At the same time, the operator no longer needs to manually start and stop the water supply pump, making water replenishment operation more convenient. Furthermore, a basket filter device 610 can be provided between the variable frequency water pump 600 and the super magnetic separation device 210 to perform a filtering function.

[0069] In a further embodiment, a drain port may be provided at a relatively low position at the bottom of the first container 100 and / or the bottom of the second container 200. This allows the water to be smoothly drained out of the container when water splashes in the first container 100 or the second container 200, thereby preventing water accumulation in the container.

[0070] In a further embodiment, the super magnetic sewage treatment system of the present application further includes an electrical control box 800, through which an operator can control the operating status of each device in the entire super magnetic sewage treatment system. Preferably, the electrical control box 800 is located near the second entrance and exit of the second container 200, so that the operator can more conveniently operate the electrical control box 800.

[0071] As used herein, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0072] In this document, directional terms such as front, back, top, and bottom are defined based on the positions of components in the accompanying drawings and relative to each other, and are intended only for clarity and convenience in describing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0073] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
