However, there are a large number of fine fibers in papermaking sewage, and the fine fibers are easy to pass through the filter screen and be discharged with the sewage, which is likely to cause waste. Moreover, when collecting the fibers, the fine fibers are easy to insert into the filter holes of the filter screen, making it inconvenient to scrape the fibers from the filter screen. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic recovery device for papermaking sewage fibers to solve the technical problem that fine fibers are not easy to clean when the filter screen in the existing equipment filters and collects fibers in the sewage as mentioned in the above background technique.

[0022] See Figures 1-5 As shown, an automatic paper-making sewage fiber recovery device according to an embodiment of the present utility model includes a semi-cylindrical tank 1, a recovery assembly 2 is arranged inside the semi-cylindrical tank 1, and an auxiliary assembly 3 is arranged on the surface of the semi-cylindrical tank 1.

[0023] The recycling component 2 includes a supporting arc plate 21 which is fixedly connected to the inner wall of the semi-circular tank 1. On the outer wall of the supporting arc plate 21, two clamping rings 22 are symmetrically clamped. On the side walls of the two clamping rings 22 close to each other, a plurality of inclined frames 23 are fixedly connected in a ring shape. On the side walls of the plurality of inclined frames 23, a filter screen plate 24 is fixedly connected. On the inner walls of both sides of the semi-circular tank 1, fixed cylinders 25 are fixedly connected. A rotating shaft 26 is rotatably connected inside the two fixed cylinders 25. On the surface of the rotating shaft 26, a rotating plate 27 is fixedly connected. At the other end of the rotating plate 27, two pushing plates 29 are fixedly connected. On the inner wall of the supporting arc plate 21, two inclined sleeves 210 are fixedly connected. Springs 211 are clamped inside the two inclined sleeves 210. Push rods 212 are inserted into the two inclined sleeves 210. Control the plurality of inclined frames 23 to rotate counterclockwise towards the water inlet end of the semi-circular tank 1. When the inclined frames 23 rotate, they drive the filter screen plate 24 to sieve through the flowing sewage. Through the plurality of filter screen plates 24, the fibers in the sewage are filtered out. When the filter screen plate 24 moves to the upper end of the semi-circular tank 1, it will contact the scraping plate 28. The inclined angle of the filter screen plate 24 guides the scraping plate 28 to scrape across its surface, and then the fibers on the surface of the filter screen plate 24 are scraped off by the scraping plate 28.

[0024] See Figures 1-3 As shown, the auxiliary component 3 includes a fixing plate 31 which is fixedly connected to the upper end of one side wall of the semi-circular tank 1. On the side wall of the fixing plate 31, a motor 32 is fixedly connected. The output end of the motor 32 is fixedly connected with a gear 33. The lower end of the gear 33 is clamped with an annular tooth groove 34 which is opened on the outer circular side wall of the clamping ring 22. An opening 35 is opened on one end side wall of the semi-circular tank 1. The motor 32 drives the gear 33 to rotate. When the gear 33 rotates, it drives the clamping ring 22 to rotate through the annular tooth groove 34. The clamping ring 22 drives the plurality of inclined frames 23 to rotate, and controls the plurality of inclined frames 23 to rotate counterclockwise towards the water inlet end of the semi-circular tank 1.

[0025] The upper end of the rotating plate 27 is fixedly connected with a scraping plate 28 which is attached to the plurality of filter screen plates 24. The fibers stuck on the surface of the filter screen plates 24 are scraped off by the scraping plate 28.

[0026] The push rod 212 is attached to the side walls of the two pushing plates 29. At one end of the push rod 212 in contact with the pushing plates 29, two inclined surfaces are symmetrically opened. The push rod 212 can be used to push the pushing plates 29 to rotate, and then drive the rotating shaft 26 to rotate back to drive the scraping plate 28 to fit with the filter screen plate 24.

[0027] The outer wall of the clamping ring 22 is attached to the inner wall of the semi-circular tank 1, and the inner wall of the clamping ring 22 is attached to the outer wall of the supporting arc plate 21, so that the plurality of clamping rings 22 block the sewage inside and prevent the sewage from flowing through both sides of the clamping ring 22, resulting in the sewage with fibers being discharged without being filtered.

[0028] When the embodiment of the present utility model is used, papermaking sewage is continuously poured from one side of the semi-circular tank 1, and the papermaking sewage is sucked out from the other side of the semi-circular tank 1, so that the papermaking sewage needs to flow through the space between the support arc plate 21 and the semi-circular tank 1. The motor 32 is started to drive the gear 33 to rotate. When the gear 33 rotates, the clamping ring 22 is driven to rotate through the annular tooth groove 34. The clamping ring 22 drives a plurality of inclined frames 23 to rotate, and the rotation of the plurality of inclined frames 23 is controlled to rotate counterclockwise towards the water inlet end of the semi-circular tank 1. When the inclined frames 23 rotate, they drive the filter screen plate 24 to sieve through the flowing sewage, and the plurality of filter screen plates 24 filter out the fibers in the sewage. When the filter screen plate 24 moves to the upper end of the semi-circular tank 1, it will contact the scraping plate 28. The inclination angle of the filter screen plate 24 guides the scraping plate 28 to scrape on its surface, and then the fibers on the surface of the filter screen plate 24 are scraped off by the scraping plate 28. The scraped fibers fall into the inside of the support arc plate 21. At the same time, the push plate 29 is driven to rotate by the spring 211 and the push rod 212. The push plate 29 drives the rotating plate 27 and the scraping plate 28 at the upper end to rotate on the surface of the filter screen plate 24 rotating counterclockwise, and the fibers on the filter screen plate 24 are sequentially scraped off. The filter holes on the filter screen plate 24 are vertically arranged in strips, which is convenient for the scraping plate 28 to pull out the fiber filaments from the filter holes and prevent the fibers from being stuck in the filter holes and unable to be scraped out.

[0029] The basic principles of the present invention have been shown and described above. The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent replacements, and improvements made within the spirit and scope of the present invention shall be included in the protection scope of the present invention.
