[0002] At present, magnetic separation water purification equipment has become an indispensable equipment in environmental protection work. However, the water purification equipment currently used is huge in size and has poor portability. The equipment can only be used in fixed locations, and a large amount of construction and installation costs are required. In addition, when the sewage reaches the sedimentation tank, the water purification equipment currently used still has a lot of small particles of flocculent impurities. These impurities will flow into the clean water tank through the overflow tank with the water, and finally be discharged with the clean water. This obviously cannot meet the water quality requirements of the city for water reuse. In addition, not every existing water purification equipment is equipped with explosion-proof electrical appliances, which will reduce the universality of the water purification equipment and make the water purification equipment unable to meet the use requirements in workplaces with explosion-proof requirements.

[0018] like Figures 1 to 3As shown, a container-type high-density solid-liquid separation explosion-proof magnetic separation water purification equipment includes a box body 1 and explosion-proof electrical appliances. The box body 1 has a cavity, which is divided into a mixing tank 2, a sedimentation tank 3 and a clean water tank 4. The mixing tank 2, the sedimentation tank 3 and the clean water tank 4 are connected in sequence; the mixing tank 2 is filled with a coagulant, and the coagulant is used to cause a condensation reaction in the sewage; the sedimentation tank 3 is equipped with a filter tube assembly and a scraper assembly, the filter tube assembly separates clean water and impurities, and the scraper assembly collects impurities and enters the magnetic separator 32 through a discharge pipe; the clean water enters the clean water tank through an overflow trough 31 and is finally discharged through a water outlet pipe; the clean water enters the clean water tank 4 through an overflow trough 31 and is finally discharged through a water outlet pipe. Sewage enters the equipment from the mixing tank 2 and reacts with the coagulant and magnetic powder, so that the impurities in the water react with the magnetic powder and coagulant to form high-density floccules, and then enters the sedimentation tank 3. After entering the sedimentation tank 3, the high-density floccules with large weight will naturally settle to the bottom of the sedimentation tank 3, and finally be sent to the magnetic separator 32 through the sludge scraper assembly. The magnetic separator 32 recovers the magnetic powder and discharges the sludge impurities. The high-density floccules with small weight will move upward with the clean water. When moving to the filter tube assembly, the high-density floccules will generate friction with the filter tube assembly, so that the high-density floccules will remain at the filter tube assembly. After a long period of filtration, the high-density floccules with small weight will become heavier after a long period of accumulation, and finally sink to the bottom of the sedimentation tank 3. They are collected by the sludge scraper assembly and sent to the magnetic separator 32. Finally, after the magnetic powder is recovered, the impurities are discharged from the box 1. The box 1 is placed on a transport vehicle, and the equipment can be transported to any designated location, such as rural areas, fields, Gobi deserts and other places where environmental protection facilities are not perfect, or even places where environmental protection equipment cannot be installed. The transport vehicle not only improves the flexibility of the equipment, but also saves huge infrastructure costs, and there is no need to build additional production workshops. In some special working conditions such as oil fields, coal mines and other places, environmental protection equipment is very much needed for environmental protection treatment. By adding explosion-proof electrical equipment to meet explosion-proof requirements, the universality of the equipment is improved.

[0019] The mixing tank 2 includes a stirring zone 11 and a flocculation zone 12. The stirring zone 11 is provided with a mixing agitator 13, and the flocculation zone 12 is provided with a flocculation agitator 14. The stirring zone 11 and the flocculation zone 12 are connected. The stirring zone 11 is provided with a water inlet 15, and the sewage enters the stirring zone 11 from the water inlet 15 through a pipeline. The mixing agitator 13 stirs the sewage and the coagulant to fully react, so that the impurities in the sewage form flocculated objects, which are convenient for later filtration. The mixing agitator 13 is provided with multiple sets of blades 28. During the rotation of the blades 28, the sewage and the coagulant are fully mixed to improve the purification degree of the sewage. Baffles are provided on both sides of the flocculation zone 12.

[0020] The sedimentation tank 3 includes a clean water area 21, a filter area 22 and a sludge area 23, which are arranged in order from top to bottom; the overflow tank 24 connects the clean water area 21 with the clean water tank 4, the filter tube assembly is located in the filter area 22, and the filter tube assembly can filter the sludge in the clean water, and the scraper assembly is located in the sludge area 23. The scraper assembly sends the sludge from the sludge area 23 to the magnetic separator 32 through the discharge pipe, and finally recovers the magnetic powder and discharges the sludge from the box 1. After being treated in the flocculation area 12, the sewage enters the sludge area 23. After entering the sludge area 23, the clean water moves upward along with the sewage into the sludge area 23, and the heavy impurities will settle to the bottom of the sludge area 23. The light impurities will move upward with the clean water. When they move to the filter tube assembly, the impurities will rub against the filter tube assembly, causing the light impurities to remain on the filter tube assembly. The long-term accumulation will increase the weight of the impurities and eventually settle to the bottom of the sedimentation tank 3 and be sent to the magnetic separator 32 by the mud scraper assembly.

[0021] The filter tube assembly includes a filter tube 24, which connects the clean water area 21 and the sludge area 23, and is connected to the filter area 22 at an angle of 60 degrees to the horizontal line. The filter tube 24 is fixed obliquely to the filter area 22, which increases the contact area between the small weight flocs and the filter tube 24, enhances the filtering capacity, and ensures the purification degree.

[0022] The scraper assembly includes a motor 25, a linkage shaft 26 and a scraper blade 27, wherein the scraper blade 27 is connected to the moving end of the motor 25 via the linkage shaft 26; the scraper blade 27 is attached to the bottom of the sludge area 23, and when the motor 25 is started, the scraper blade 27 will rotate, and the scraper blade 27 will suck the solid impurities deposited at the bottom of the sedimentation tank 3 into the magnetic separator 32 through the residual sludge pump.

[0023] The mixing tank 2 is at the same height as the sedimentation tank 3, and the cross-sectional area of ​​the sedimentation tank 3 is larger than that of the mixing tank 2. According to the shallow tank theory, when the volume and height are equal, the larger the cross-sectional area, the higher the sedimentation efficiency, and the better the sewage treatment capacity of the equipment is improved.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
