Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to an integrated fiber rotary filter for sewage treatment. Background Technology

[0002] A fiber disc filter is an integrated wastewater treatment device, primarily suitable for advanced treatment at the later stages of wastewater treatment processes. It is installed after a conventional secondary wastewater treatment system or after the secondary sedimentation tank in a conventional secondary wastewater treatment system. Its main function is to remove total suspended particulate matter (TSP) from the water. For example, the existing patent CN217489854U discloses "An Integrated Fiber Disc Filter for Domestic Wastewater Treatment," which relates to the field of wastewater treatment technology and addresses the problem of difficult removal of bottom sludge from existing integrated fiber disc filters for domestic wastewater treatment. The integrated fiber disc filter internally includes an inlet weir, a treatment tank, and an outlet weir, all of which are integrally structured with the filter. The application describes a common integrated fiber disc filter for wastewater treatment, which is equipped with friction rollers inside the filter tank. This type of integrated fiber disc filter typically consists of a central water collection cylinder, fiber filter discs, a drive reducer and chain, a backwash electric valve, a backwash suction cup and backwash pump, an intelligent level and pressure transmitter, a control cabinet, a bottom sludge discharge pipe, a backwash assembly and backwash pipeline, and other accessories. During operation, the filter is completely submerged in the water in the filter tank. The raw water flows into the inner cavity of the discs after being filtered through the filter cloth. Since the filtration accuracy of the filter cloth is ≤10um, the SS concentration in the water flowing into the inner cavity of the discs after passing through the filter cloth has reached the Class A discharge standard. The water in the inner cavity of the discs flows into the central water collection cylinder through the collection holes and is then discharged to the outside of the filter tank, thus achieving integrated treatment of wastewater.

[0003] In existing integrated fiber disc filters for wastewater treatment, wastewater flows directly into the treatment tank after entering the water tank through pipes without any preliminary filtration measures. This undoubtedly increases the filtration burden on the fiber discs, requiring operators to clean them regularly and reducing the treatment effect. Therefore, this invention aims to improve and optimize this type of integrated fiber disc filter for wastewater treatment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 4This is the first embodiment of the present invention, which provides a technical solution: an integrated fiber rotary filter for wastewater treatment, comprising...

[0025] The system comprises a pool body 1, a treatment pool 2, an effluent pool 3, and an influent pool 6 located inside the pool body 1, a fiber turntable 7 rotatably installed inside the treatment pool 2, and a reduction motor 4 installed on the top of the pool body 1. The output end of the reduction motor 4 is connected to the central shaft of the fiber turntable 7 via a chain, so that when the reduction motor 4 starts, it can drive the fiber turntable 7 to rotate via the chain. After the sewage enters the influent pool 6, it flows into the treatment pool 2 and is filtered by the fiber turntable 7. The filtered water enters the effluent pool 3 through the hollow pipe inside the fiber turntable 7 and is then discharged to the outside, thus completing the treatment of sewage. The above structural principles are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN217489854U. Further details will not be elaborated here.

[0026] The system also includes a detachable coarse filter assembly, comprising a rectangular top plate 51 and two rectangular insert frames 54 welded and fixed to the bottom of the rectangular top plate 51. Metal filter screens 55 are installed inside the rectangular insert frames 54. The rectangular top plate 51 is installed on the top surface of the tank body 1, and both rectangular insert frames 54 extend into the inner side of the inlet tank 6. This allows wastewater to undergo preliminary coarse filtration by the two metal filter screens 55 after entering the inlet tank 6 through the inlet pipe 12, filtering out some larger impurities and foreign objects in the wastewater. Then, the wastewater flows into the treatment tank 2 and is further refined by the fiber disc 7. This improves the filtration efficiency of the wastewater and reduces the filtration burden on the fiber disc 7. In the later stages, it is only necessary to periodically remove the rectangular insert frames 54 to rinse the impurities filtered out by the metal filter screens 55.

[0027] In this embodiment, preferably, the detachable coarse filter assembly further includes a rotating retaining bar 52 rotatably mounted on the top of the rectangular top plate 51 via a rotating shaft. Limiting structures 53 are provided at both ends of the top of the tank body 1 relative to the rotating retaining bar 52. The limiting structures 53 include a support 531 welded and fixed to the top surface of the tank body 1, and an L-shaped movable plate 532 movably mounted on the side of the support 531. The top end of the L-shaped movable plate 532 extends in a bent shape to the top of the rotating retaining bar 52, and an arc-shaped retaining block 533 is welded and fixed to the inner side of the top end of the L-shaped movable plate 532. Both ends of the rotating retaining bar 52 have openings... A circular locking hole 534 corresponds to the arc-shaped locking block 533. The arc-shaped locking block 533 is inserted into the circular locking hole 534 to engage and limit the rotating locking strip 52, ensuring that the end of the rotating locking strip 52 remains at the bottom of the L-shaped movable plate 532 during daily use, thereby ensuring the installation stability of the rectangular top plate 51. The limiting structure 53 also includes a T-shaped side groove 535 formed on the side of the support 531 and a T-shaped slide block 537 slidably disposed in the T-shaped side groove 535. The end of the T-shaped slide block 537 extends to the side of the support 531 and is fixed to the L-shaped movable plate 532. The positioning structure 53 also includes a spring 536 installed in the T-shaped side groove 535. Under the pushing action of the spring 536, the arc-shaped locking block 533 can be stably locked in the circular locking hole 534 during daily use, and the top of the L-shaped movable plate 532 can be stably pressed against the top of the rotating locking strip 52, thus stably limiting the rotation locking strip 52. If the rectangular insert frame 54 and the metal filter screen 55 need to be removed for cleaning and maintenance, simply push the rotating locking strip 52 forcefully. Due to the arc-shaped structure of the arc-shaped locking block 533, the end of the rotating locking strip 52 will be pushed to lock the arc-shaped locking block 533. Block 533 and L-shaped movable plate 532 are pressed upwards, causing L-shaped movable plate 532 to slide upwards and move T-shaped slide 537 upwards, and compressing spring 536 until arc-shaped locking block 533 is squeezed out into circular locking hole 534. The end of rotating locking strip 52 can then be easily selected from the inside of the top of L-shaped movable plate 532. Once rotating locking strip 52 is no longer blocked by L-shaped movable plate 532, rotating locking strip 52 and rectangular top plate 51 can be lifted directly, and rectangular insert frame 54 and metal filter screen 55 can be easily pulled out for cleaning and maintenance, ensuring convenient maintenance in the later stages.

[0028] In this embodiment, preferably, the top end of the spring 536 is fixed to the inner wall of the top end of the T-shaped side groove 535, and the bottom end of the spring 536 is fixed in a circular groove opened on the top surface of the T-shaped slide block 537, so as to ensure the installation stability of the spring 536.

[0029] In this embodiment, preferably, a handle 521 is welded and fixed at the top center of the rotating clip 52 to facilitate the subsequent rotation and lifting of the rotating clip 52.

[0030] In this embodiment, preferably, a water outlet pipe 11 communicating with the water outlet pool 3 is provided on one side surface of the pool body 1, and a water inlet pipe 12 communicating with the water inlet pool 6 is provided on the other side surface of the pool body 1 for the inlet and outlet of sewage.

[0031] Example 2

[0032] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that a base 13 is welded and fixed to the bottom inner wall of the water inlet pool 6, and two rectangular slots 131 are opened on the top of the base 13. The bottom end of the rectangular insert frame 54 is inserted into the rectangular slot 131, which can effectively support the bottom end of the rectangular insert frame 54.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
