[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a filter tank magnetic separation aeration device, comprising a sewage treatment tank 1, a partition 2 is arranged in the sewage treatment tank 1, the partition 2 divides the sewage treatment tank 1 into an aeration tank 3 and a sedimentation tank 9, a channel connecting the aeration tank 3 and the sedimentation tank 9 is arranged at the bottom of the partition 2, an aeration pipe is arranged in the aeration tank 3, a water inlet is arranged at the top of one side of the aeration tank 3, the sedimentation tank 9 is used to settle large volume of sludge, an overflow tank 4 is connected to the downstream side of the sewage treatment tank 1, the overflow tank 4 is connected to the sedimentation tank 9, a water outlet close to the top is arranged on one side of the overflow tank 4, when sewage is treated, sewage enters from the water inlet and is discharged through the water outlet after treatment.

[0023] In the present technical solution, a belt drive mechanism 5 is provided above the overflow tank 4. The bottom of the transmission belt 51 on the belt drive mechanism 5 is recessed downward and extends into the overflow tank 4. The inner and outer sides of the lower part of the transmission belt 51 are in contact with the water body in the overflow tank 4, thereby increasing the contact area with the water body. The transmission belt 51 is embedded with circumferentially uniformly distributed magnetic strips 7. The magnetic strips 7 generate magnetic attraction on the inner and outer sides of the entire transmission belt 51, thereby adsorbing flocculants containing magnetic powder flowing through the overflow tank 9, thereby increasing the adsorption amount of flocculants in sewage.

[0024] A scraper part 6 for scraping mud from the inner and outer sides of the conveyor belt 51 is arranged above the overflow tank 4. The scraper part 6 is located below the transmission roller on the belt transmission mechanism 5. A sludge collecting box 8 is arranged on the left and right sides of the scraper part 6 on the top of the overflow tank 4. The scraper part 6 has the function of scraping off the flocculants adsorbed on the inner and outer sides of the conveyor belt 51, and then introducing them into the sludge collecting box 8, so as to facilitate the operation of the conveyor belt 51 to continue to magnetically separate impurities in the sewage.

[0025] Specifically, a tensioning frame 521 is connected to the outer side of the frame 52 on the belt transmission mechanism 5 in an up and down sliding manner. A tensioning roller 5211 is provided at the bottom of the tensioning frame 521, which abuts against the inner side of the lower part of the transmission belt 51. The tensioning frame 521 is a door-type frame structure. Guide sleeves mounted on two vertical rods on the tensioning frame 521 can be welded on both sides of the frame 52, and then a support spring is provided between the guide sleeve and the vertical rod, thereby enabling the lower part of the transmission belt 51 to be pushed into the overflow tank 4 through the tensioning roller 5211.

[0026] Furthermore, the outer wall of the tensioning roller 5211 is fixedly connected with a baffle 52111 evenly distributed in the circumferential direction. The baffle 52111 acts as a pad, which can reduce the contact area between the tensioning roller 5211 and the inner side of the transmission belt 51, thereby avoiding squeezing and separating impurities that have been adsorbed by the transmission belt 51 over a large area.

[0027] In this embodiment, the scraper part 6 includes two V-shaped scrapers 61, which are respectively arranged on the inner and outer sides of the conveyor belt 51. The small end of the V-shaped scraper 61 faces the upstream side of the conveyor belt 51. When the conveyor belt 51 is running, the V-shaped scraper 61 will divert the flocculants adsorbed on the conveyor belt 51 to both sides and push them into the sludge collection box 8.

[0028] Furthermore, the scraper 6 includes an elastic telescopic frame 1 62 and an elastic telescopic frame 2 63, the tops of which are fixedly connected to the two sides of the frame 52, and the bottoms of which are fixedly connected to the small ends of the two V-shaped scrapers 61, respectively, wherein the elastic telescopic frame 1 62 is used to apply a downward elastic thrust to the V-shaped scraper 61 located on the inner side of the transmission belt 51, and the elastic telescopic frame 2 63 is used to apply an upward elastic pulling force to the V-shaped scraper 61 located on the outer side of the transmission belt 51. Among them, the elastic telescopic frame 1 62 and the elastic telescopic frame 2 63 are both door-type telescopic frame structures.

[0029] In this embodiment, a rubber scraper strip 611 is provided on the side opposite to the V-shaped scraper plate 61 and the belt body of the transmission belt 51 . The function of the rubber scraper strip 611 is to avoid damaging the transmission belt 51 .

[0030] Working principle: When in use, the magnetic powder in the aeration tank 3 combines with the flocculants in the sewage, and then flows into the sedimentation tank 9 with the water flow. The water body containing the magnetic powder and flocculants at the top of the sedimentation tank 9 enters the overflow tank 4, the transmission mechanism 5 is started, and the transmission belt 51 is operated. Under the action of the magnetic strip 7, the inner and outer sides of the transmission belt 51 in the water body will absorb the flocculants containing the magnetic powder. After the flocculants leave the water surface with the transmission belt 51, they will be scraped off and pushed to the two sides of the transmission belt 51 when passing through the V-shaped scraper 61, and then fly into the sludge collection box 8 to clean the impurities in the sewage.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
