[0002] Traditional wastewater treatment methods, such as simple physical filtration and chemical precipitation, have limited effectiveness in removing magnetic pollutants and are unable to meet increasingly stringent environmental standards.
[0003] Currently, although some wastewater treatment devices exist on the market, they generally suffer from low treatment efficiency and poor results. Some devices focus only on treating single pollutants, failing to comprehensively consider the characteristics of multiple pollutants in wastewater; for example, when dealing with wastewater containing magnetic pollutants, they lack targeted treatment measures and cannot efficiently remove magnetic pollutants, resulting in treated water quality that still does not meet requirements. Therefore, developing a wastewater filtration device that can efficiently remove magnetic pollutants from wastewater is of significant practical importance. Utility Model Content

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] Example 1:
[0024] like Figure 1 As shown, a wastewater filtration device based on magnetic adsorption includes a filtration unit and a magnetic adsorption unit.
[0025] The filtration unit includes a sewage tank 1, with a sewage inlet 3 fixedly connected to the upper end of the sewage tank 1. A sewage filter 2 is fixedly connected inside the sewage tank 1, and a drain pipe 4 is connected to the lower part of the sewage filter 2. When sewage enters the sewage tank 1 through the sewage inlet 3, it will enter the sewage filter 2. After being coarsely filtered by the sewage filter 2, the sewage will fall below the sewage filter 2. The filtered impurities will be discharged through the drain pipe 4, completing the first filtration of the sewage.
[0026] The wastewater filter 2 includes a coarse filter screen, an activated carbon adsorption layer, and a fine filter screen that are fixedly connected inside the wastewater tank 1. The coarse filter screen, the activated carbon adsorption layer, and the fine filter screen are arranged in order from top to bottom. The coarse filter screen, the activated carbon adsorption layer, and the fine filter screen are all detachably installed inside the wastewater tank 1 through slots.
[0027] The wastewater filtration device also includes a sewage tank 5, and the other end of the sewage pipe 4 is connected to the sewage tank 5. The filtered impurities can be collected through the sewage tank 5.
[0028] The magnetic adsorption unit includes an adsorption box 8. A water pump 6 is fixedly connected to the lower end of the sewage tank 1, and a water inlet 9 is fixedly connected to the upper end of the adsorption box 8. The water pump 6 and the water inlet 9 are connected by a pipe 7. The water filtered inside the sewage tank 1 is output through the water pump 6 and then enters the adsorption box 8 through the pipe 7 and the water inlet 9.
[0029] The adsorption chamber 8 is equipped with multiple magnetic rods 11 arranged in a rectangular array. The lower ends of the magnetic rods 11 are fixedly connected to magnetic pollutant storage areas 12, which can be circular magnetic plates. The upper end of the adsorption chamber 8 is fixedly connected to multiple vibration motors 10 that are compatible with the magnetic rods 11. The vibration motors 10 and the magnetic rods 11 are fixedly connected. At this time, the magnetic rods 11 and the magnetic pollutant storage areas 12 come into contact with the magnetic pollutants in the sewage, adsorbing the magnetic pollutants in the sewage. After adsorption for a period of time, the vibration motors 10 are started to make the magnetic rods 11 and the magnetic pollutant storage areas 12 vibrate, causing the magnetic pollutants on the magnetic rods 11 and the magnetic pollutant storage areas 12 to fall off and fall into the bottom of the adsorption chamber 8. The lower end of the adsorption chamber 8 is fixedly connected to an electric valve 14. At this time, the electric valve 14 is opened, and the magnetic pollutants are discharged through the electric valve 14.
[0030] By organically combining the magnetic adsorption unit and the filtration unit, the wastewater is first purified by the filtration unit and then magnetic pollutants are removed by magnetic adsorption, which greatly improves the effect and efficiency of wastewater treatment.
[0031] Here, the magnetic rod 11 and the magnetic contaminant storage area 12 can be made of magnets or electromagnets.
[0032] Meanwhile, multiple baffles 13 can be fixedly connected to the lower side of the adsorption box 8. The baffles 13 are located between multiple magnetic rods 11. Through the setting of the baffles 13, the magnetic pollutants in the sewage can be in contact with the magnetic rods 11 and the magnetic pollutant temporary storage area 12 more evenly. The baffle design of the magnetic adsorption unit and the reasonable combination of different filter media of the filter unit give full play to the synergistic effect of the two.
[0033] The top of the sewage tank 1 may also be equipped with a backwash water pipe, which is connected to an external backwash water source, and a control valve is installed on the backwash water pipe. The sewage discharge pipe 4 at the bottom of the sewage tank 1 and the electric valve 14 at the bottom of the magnetic adsorption unit are connected to the main sewage discharge pipe through a T-junction, and a sewage pump is installed on the main sewage discharge pipe.
[0034] Example 2:
[0035] like Figures 1-3 As shown, the difference between this embodiment and Embodiment 1 is that multiple movable magnetic plates 23 are also assembled on the outside of the magnetic rod 11 to enhance the magnetic adsorption effect. The movable magnetic plates 23 can move on the outside of the magnetic rod 11. By adjusting the locking position of the movable magnetic plates 23, the magnetic adsorption range of the magnetic pollutant storage area 12 and the movable magnetic plates 23 can be adjusted, so that both the magnetic pollutant storage area 12 and the movable magnetic plates 23 can be located in the sewage inside the adsorption box 8. This allows the magnetic adsorption capacity of the magnetic pollutant storage area 12 and the baffle plate 13 to be concentrated to adsorb the magnetic pollutants in the sewage, ensuring the adsorption effect.
[0036] Specifically, the movable magnetic plate 23 is slidably connected to the outside of the magnetic rod 11. The movable magnetic plate 23 can be moved by multiple electric push rods 24. That is, multiple electric push rods 24 are fixedly connected to the outside of the magnetic rod 11, and each of them is opposite to the movable magnetic plate 23. The piston rods of the multiple electric push rods 24 are fixedly connected to the multiple movable magnetic plates 23 respectively. By activating the electric push rods 24, the corresponding movable magnetic plates 23 can be moved.
[0037] The movable magnetic plate 23 can also be moved by an electric valve 14. Tension springs 15 are fixedly connected between two adjacent movable magnetic plates 23 and between adjacent magnetic contaminant storage areas 12 and movable magnetic plates 23. An electric push rod 24 is fixedly connected to the upper part of the outer side of the magnetic rod 11. The output end of the electric push rod 24 is fixedly connected to the uppermost movable magnetic plate 23. At this time, by starting the electric push rod 24, the uppermost movable magnetic plate 23 is moved, and then the tension springs 15 are used to move the remaining movable magnetic plates 23, so that the positions of multiple movable magnetic plates 23 can be adjusted.
[0038] like Figures 2-3 As shown, in order to ensure the stability of the movable magnetic plate 23, a locking component is also installed on the movable magnetic plate 23. A sliding ring 16 is fixedly connected to the upper side of the movable magnetic plate 23 and is slidably connected to the outside of the magnetic rod 11. A sleeve 17 is fixedly connected to the outside of the sliding ring 16. An electromagnet base 18 is fixedly connected to one end inside the sleeve 17. A magnetic plate 19 is slidably connected to the inside of the sleeve 17 and to the side of the electromagnet base 18 near the magnetic rod 11. A push rod 21 that can extend to the outside of the sleeve 17 and abut against the magnetic rod 11 is fixedly connected to the magnetic plate 19. A return spring 20 is fixedly connected between the electromagnet base 18 and the magnetic plate 19. When the electromagnet base 18 is energized, it and the magnetic plate 19 are magnetically attracted to each other.
[0039] When the movable magnetic plate 23 is moved, the magnetic plate 19 is attracted by the electromagnet base 18, which separates the top rod 21 and the magnetic rod 11, thus releasing the lock on the movable magnetic plate 23.
[0040] After the movable magnetic plate 23 has moved, the power to the electromagnet base 18 is turned off, and the push rod 21 and the magnetic rod 11 will abut against each other under the elastic action of the return spring 20, thus locking the movable magnetic plate 23.
[0041] Meanwhile, multiple positioning holes 22 are provided on the outer side of the magnetic rod 11, and the top rod 21 can be inserted into any of the positioning holes 22 to improve the locking effect on the movable magnetic plate 23.
[0042] Meanwhile, an anti-rotation groove is provided on the outer side of the magnetic rod 11, and an anti-rotation block is fixedly connected to the inner wall of the sliding ring 16. The anti-rotation block is slidably connected inside the anti-rotation groove.
[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
