Description

Technical Field

[0001] The present invention relates to the field of sewage, and in particular to a flat-plate magnetic separation device and method. Background Art

[0002] Magnetic separation technology is a technology that separates substances through the magnetic field suction provided by magnets (physical separation method). It was developed in the United States in the early 1970s. This technology can quickly separate magnetic impurities in a mixture. Magnetic separation technology is widely used in the field of sewage treatment. It uses the magnetism of impurity particles in wastewater for separation. For non-magnetic or weakly magnetic particles in water, magnetic inoculation technology can make them magnetic. With the help of external magnetic fields, magnetic suspended solids in wastewater are separated, thereby achieving the purpose of purifying water.

[0003] At present, in the super magnetic sewage treatment process, fine magnetic seeds are added to the sewage at the same time as flocculants and coagulants. The pollutants in the sewage form flocs containing magnetic seeds under the action of chemical agents. When the sewage containing the flocs passes through a specific magnetic device, the flocs will be adsorbed by the magnetic device under the action of the magnetic field and separated from the magnetic device under the action of the separation mechanism, and enter a specific floc breaking mechanism, thereby realizing the separation of the magnetic seeds and the flocs, and achieving the purpose of recycling the magnetic seeds.

[0004] Patent (207313207U) invented a scraping mechanism for sewage treatment, which uses a combination of a scraping bar assembly and a pocket bar assembly, but cannot completely scrape off the flocculent sludge containing magnetic seeds from the magnetic disk device. The main reason is that the entire scraping process is completed on a magnetic disk with a strong magnet. Due to the large magnetic force of the magnetic disk, a small amount of flocculent sludge will still be adsorbed on the magnetic disk, resulting in the inability to completely separate the flocculent sludge from the magnetic device, which reduces the sewage treatment efficiency. At the same time, the scraping mechanism is not easy to repair, the magnetic disk processing and assembly are complicated, the pocket bar has a short service life and needs to be replaced frequently, and the processability is poor.

[0088] Example 3

[0089] The present invention provides a method for magnetic separation by a flat-plate magnetic separation device, such as Fig. 9 As shown:

[0090] 1) In the present invention, the gate 12 is driven by the A cylinder 11 to move vertically up and down, so that the flat-plate magnetic separation device can be provided with untreated sewage in an intermittent manner. When the piston rod of the A cylinder 11 is extended, the gate 12 moves downward, at which time the gate is closed and the sewage stops entering the flat-plate magnetic separation device; when the piston rod of the A cylinder 11 is retracted, the gate 12 moves upward, at which time the gate is opened and the sewage enters the flat-plate magnetic separation device;

[0091] 2) In the present invention, the lifting base 228 is driven to move up and down in the vertical direction by the B cylinder 222, and the magnetic separation tank is moved up and down in the vertical direction by the magnetic separation tank support plate 229; the counterweight effect can be achieved by the combination of the counterweight lead block 224, the guide wheel 225, the chain 226, and the sprocket 227, that is, to prevent the B cylinder 222 from having insufficient lifting force; the magnetic force of the magnetic plate 212 can realize the adsorption of the magnetic flocs in the sewage by the upper surface of the magnetic separation tank 221; the synchronous toothed belt 235 can be driven to move horizontally by the drive motor 236, and then the scraper assembly 231 can be driven to move horizontally; the nylon scraper plate 2311 is in contact with the upper surface of the magnetic separation tank 221, so that the magnetic flocs adsorbed on the upper surface of the magnetic separation tank 221 can be scraped and scraped into the sludge tank 34 in the water outlet tank mechanism 3. When the piston rod in the B cylinder 222 is in a retracted state, that is, the magnetic separation tank 21 is in the lowest position, the distance between the magnetic plate assembly 21 and the magnetic separation tank 22 is the smallest, that is, the magnetic force of the magnetic plate 212 is the largest, and at this time, the magnetic flocs with magnetic seeds in the sewage are adsorbed to the upper surface of the magnetic separation tank 221 through the magnetic force of the magnetic plate 212; when the piston rod in the B cylinder 222 is in an extended state, that is, the magnetic separation tank 21 is in the highest position, the distance between the magnetic plate assembly 21 and the magnetic separation tank 22 is the largest, that is, the magnetic force of the magnetic plate 212 is the smallest, and at the same time, the upper surface of the magnetic separation tank 21 contacts the nylon scraper plate 2311 in the scraper assembly 231 and compresses the spring 2313, and at this time, the synchronous toothed belt 235 is driven by the driving motor 236 to move horizontally, and then the scraper assembly 231 is driven to move horizontally, and finally the scraping of the flocs with magnetic seeds on the upper surface of the magnetic separation tank 21 is completed, and it is scraped into the sludge tank 34 in the water outlet tank mechanism 3;

[0092] 3) In the present invention, the scraper cylinder 33 drives the scraper plate 39 to scrape the magnetic flocs in the sludge tank 34 and discharge them at the sludge discharge port 321; the C cylinder 36 can drive the movable guide plate 310 to move back and forth, so that the magnetic flocs scraped from the magnetic separation tank 211 can be guided to the sludge tank 34, and the magnetic flocs will not flow into the outlet tank 32. When the magnetic separation tank 21 is at the lowest position, the piston rod in the C cylinder 36 contracts and the movable guide plate 310 is in a retracted state. At this time, the movable guide plate does not play any role and the scraper cylinder 33 does not move. At this time, the clean water flowing from the magnetic separation tank 21 enters the water outlet trough 32 and is discharged from the clean water outlet 31; when the magnetic separation tank 21 is at the highest position, the piston rod in the C cylinder 36 extends, and the movable guide plate 310 is in an extended state. The movable guide plate plays a guiding role. At this time, the flocs with magnetic seeds scraped from the magnetic separation tank 21 enter the sludge tank 34, and then the scraper cylinder 33 moves, driving the scraper plate 39 to scrape the flocs with magnetic seeds in the sludge tank 34 and discharge them at the sludge outlet 321.
