Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a fully immersed fiber rotary disc filter. Background Art

[0002] The fully submerged fiber disc filter is a filtering device used for water treatment. It mainly consists of multiple rotating discs that can rotate together and fiber bundles on the discs. During operation, water is injected into the device and enters the outlet pipe through the fiber disc. In this process, the water comes into contact with the fiber bundle, and the impurities, particles and pollutants in it are captured on the fiber surface.

[0003] This filter works similarly to other fiber filters, but its fully submerged design allows water to flow freely throughout the device, making the filtration more efficient. The density and material of the fiber bundles are usually designed to capture different sizes and types of contaminants. Once the fiber surface is contaminated, it is usually cleaned by reversing the water flow or cleaning the device to ensure the continued effective operation of the device.

[0004] Existing cleaning devices are usually multiple scrapers fixedly connected to the filter, and these scrapers are in contact with the outer surface of the fiber disk. When the outer surface of the fiber disk needs to be cleaned, the driving device on the fully immersed fiber disk filter will drive the multiple fiber disks to rotate, so that the pollutants on the fiber disk are scraped off by the scrapers. However, after the fiber disk has been used for a period of time, the originally tight outer surface may become loose. At this time, the scraper cannot fit tightly with the outer surface of the fiber disk, so that the pollutants on the surface of the fiber disk cannot be scraped off by the scraper, resulting in poor cleaning effect. To this end, we propose a fully immersed fiber disk filter. Utility Model Content

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 In the figure, the fixing assembly includes a concave carrier plate 6 and a plurality of screw holes 15. The concave carrier plate 6 is fixedly connected to one side surface of the inner part of the filter body 1, and the concave portion of the concave carrier plate 6 is fitted with the mounting plate 3.

[0026] See also Figure 7 In the figure, a rectangular groove 14 is provided at the front end of the concave plate 10 corresponding to the scraper 8, and the rectangular groove 14 and the scraper 8 are slidably matched.

[0027] See also Figure 6 In the figure, one end of the guide column 11 away from the concave plate 10 is fixedly connected to the limiting plate 12, and the end of the limiting plate 12 corresponding to the concave plate 10 is in contact with the outer wall of the rectangular plate 9; specifically, the setting of the limiting plate 12 can prevent the rectangular plate 9 from sliding off the corresponding guide column 11.

[0028] See also Figure 3 , Figure 5 and Figure 7In the figure, a plurality of concave handles 5 are fixedly connected to the upper end of the mounting plate 3 in a linear array from front to back.

[0029] Working principle: when it is necessary to scrape off the surface pollutants of the multiple turntable bodies 2 on the filter body 1, the multiple turntable bodies 2 will rotate in the filter body 1 (this is a well-known existing technology and will not be elaborated), and the multiple scrapers 8 can scrape off the pollutants on the surface of the turntable body 2. When the outer surface of the turntable body 2 is loose, under the action of the multiple springs 13, the scraper 8 can still fit with the outer surface of the turntable body 2. In this process, the multiple springs 13 will drive the rectangular plate 9 to slide on the outer wall of the multiple guide columns 11 toward the turntable body 2, and the rectangular plate 9 will drive the scraper 8 to slide in the rectangular groove 14 on the concave plate 10 toward the turntable body 2 (the multiple springs 13 between the rectangular plate 9 and the concave plate 10 will be in an automatically shortened state on the outer wall of the corresponding guide column 11). Therefore, even if the surface of the turntable body 2 is loose, the scraper 8 can still be close to the surface of the turntable body 2, thereby ensuring that the surface pollutants on the turntable body 2 are scraped off.

[0030] When it is necessary to remove the multiple concave plates 10 and the corresponding scrapers 8 from the filter body 1 for cleaning, maintenance or replacement, the multiple knob screws 4 are rotated upward in sequence, and the multiple knob screws 4 are rotated upward in the screw holes 15 on the corresponding mounting plates 3, and the multiple knob screws 4 are also rotated upward in the inner wall of the concave carrier plate 6, until the multiple knob screws 4 are completely separated from the concave carrier plate 6, the mounting plate 3 can be removed from the concave carrier plate 6 by the concave handle 5 on the mounting plate 3, and the mounting plate 3 will drive the multiple concave connecting plates 7 to leave the filter body 1 together, and the multiple concave connecting plates 7 can drive the corresponding multiple concave plates 10 and the scrapers 8 to leave the filter body 1 together, so that the multiple concave plates 10 and the corresponding scrapers 8 can be removed from the filter body 1 for cleaning, maintenance or replacement. Similarly, the multiple concave plates 10 and the corresponding scrapers 8 can be reinstalled on the filter body 1 according to the opposite operation, which is easy to operate.

[0031] It should be noted that the scraper 8 on the filter body 1 can always fit with the outer surface of the turntable body 2, ensuring that when the outer surface of the turntable body 2 becomes loose, the scraper 8 still fits with the outer surface of the turntable body 2, thereby ensuring that the pollutants on the surface of the turntable body 2 can be scraped off by the scraper 8, which is beneficial to ensure the cleaning effect; at the same time, multiple scrapers 8 can be taken out from the filter body 1 together, which is convenient for cleaning, maintenance or replacement, and easy to disassemble and assemble.
