[0002] At present, the problem of water resource pollution is becoming increasingly prominent.

The centrifugal force generated by the rotation can throw off the impurities attached to the surface. On the other hand, the spiral scraper on the top of the long conical gear tube rotates with it, which can scrape off the stubborn particles stuck on the surface of the metal filter cartridge, and cooperate with the backwash water flow to form a synergistic effect of scraping and flushing. In addition, during the rotation process, the backwash water flow can cover all areas with the rotation of the filter cartridge, reducing the flushing blind area and completely removing the residual impurities.

[0022] Specifically, the surface of the long conical tooth tube 592 is provided with a drainage hole 1 located inside the metal filter cartridge 51, both sides of the bottom of the cross conical tooth tube 593 are provided with a drainage hole 2 located inside the high-grade filter cartridge 57, and the back of the flushing tube 594 is provided with a drainage hole 3 located inside the intermediate filter cartridge 53.

[0024] Specifically, when the water flows into the fixed box 58, the water flow pressure pushes the pad 5951 to compress the spring 5952, and the sealing plate 5954 forms a gap with the fixed box 58 to ensure that the flushing water flows smoothly to the flushing pipe 594, the long tapered tooth tube 592 and the cross tapered tooth tube 593; when the drainage pump 2 is turned off, the water pressure inside the fixed box 58 becomes smaller, and the spring 5952 will push the pad 5951 and the sealing plate 5954 to reset, and the sealing plate 5954 seals the flushing pipe 594, the long tapered tooth tube 592 and the cross tapered tooth tube 593 to prevent untreated sewage from seeping back into the filtered area.

[0025] like Figures 3 to 5 As shown, the centrifugal assembly 510 includes a motor 5101, which is fixedly connected to the left side of the fixed box 58. The output end of the motor 5101 passes through the interior of the fixed box 58 and is fixedly connected to a bevel gear rod 5102. The long bevel gear tube 592 and the cross bevel gear tube 593 are both engaged with the bevel gear rod 5102. The top of the long bevel gear tube 592 is fixedly connected to a spiral scraper 5103.

A face gear ring 5104 is fixedly connected to the top of the bottom plate 54 , and the rotating gear ring 56 is meshed with the face gear ring 5104 . The face gear ring 5104 is located outside the rotating sleeve 55 , and the bottom of the rotating sleeve 55 contacts the top of the bottom plate 54 .

[0026] Specifically, the motor 5101 is a reduction motor, which synchronously drives the long conical tooth tube 592 and the cross conical tooth tube 593 to rotate through the conical gear rod 5102, thereby driving the intermediate filter cartridge 53 and the high-grade filter cartridge 57 to rotate, and using centrifugal force to forcefully throw away the impurities attached to the surface of the high-grade filter cartridge 57. At the same time, the spiral scraper 5103 rotates with the long conical tooth tube 592 to scrape off the stubborn particles on the surface of the metal filter cartridge 51, thereby realizing synchronous cleaning of multiple structures.

[0027] like Figure 5 As shown, the right side of the pad 5951 is fixedly connected to the T-shaped rod 6, the sleeve plate 5953 is slidably sleeved on the surface of the T-shaped rod 6, and the spring 5952 is sleeved on the surface of the T-shaped rod 6.

[0028] Specifically, the T-shaped rod 6 can provide precise guidance for the spring 5952, preventing the spring 5952 from lateral displacement or twisting during compression or resetting, ensuring that the spring 5952 always exerts stable force in the axial direction, and making the opening and closing actions of the pad 5951 and the sealing plate 5954 smoother.

[0029] like Figure 2 、 Figure 3 and Figure 8 As shown, an automatic sewage discharge mechanism 7 is provided at the bottom of the water tank 1. The automatic sewage discharge mechanism 7 includes a reducer 71, which is fixedly connected to the bottom of the water tank 1. The input end of the reducer 71 passes through the water tank 1 and is fixedly connected to the bottom of the cross-beam gear tube 593. The output end of the reducer 71 is fixedly connected to a bevel gear 72. A positioning rod 73 is fixedly connected to the right side of the bottom of the water tank 1. A bevel gear cylinder 74 is slidably sleeved on the surface of the positioning rod 73. The bevel gear 72 is meshed with the bevel gear cylinder 74.

[0030] Specifically, the reducer 71 is a worm gear reducer, and the front shape of the positioning rod 73 is T-shaped. The positioning rod 73 can support and limit the bevel gear cylinder 74, thereby improving the stability of the bevel gear cylinder 74 during rotation; when in use, the cross bevel gear tube 593 drives the bevel gear 72 to rotate through the reducer 71, and the bevel gear 72 drives the bevel gear cylinder 74 to rotate. At this time, the bevel gear cylinder 74 will push the slide rod 77 to move upward through the Z-shaped ring groove 76. After rotating to the specified angle, the slide rod 77 will move downward, thereby realizing that the slide rod 77 drives the sliding sleeve 75 and the gate plate 78 to automatically complete the opening and closing actions. No human intervention is required, and sewage can be discharged through the four-way drainage pipe 511.

[0031] like Figures 3 and 4 As shown, the gate 78 includes a mouth-shaped sleeve 781, which is fixedly connected to the right side of the sliding sleeve 75.

The bottom end of the clamping plate 782 passes through the interior of the four-way drainage pipe 511. There are three clamping plates 782.

[0032] Specifically, by providing the clamping plate 782 , the four-way drain pipe 511 can be sealed to prevent water from being discharged through the four-way drain pipe 511 .

[0033] like Figure 4 As shown, the bottom of the right side of the water tank 1 is fixedly connected to a limiting sleeve 8, the limiting sleeve 8 is slidably sleeved on the surface of the mouth-shaped sleeve 781 and the sliding sleeve 75, the top of the bevel gear cylinder 74 is in contact with the bottom of the water tank 1, and the top and bottom of the right side of the fixed box 58 are fixedly connected to a positioning plate 9, and the right end of the positioning plate 9 is fixedly connected to the inside of the water tank 1.

[0034] Specifically, by setting the limiting sleeve 8, the mouth-shaped sleeve 781 and the sliding sleeve 75 can be limited, thereby improving the stability of the mouth-shaped sleeve 781 and the sliding sleeve 75 when moving up and down. By setting the positioning plate 9, the fixed box 58 can be reinforced, thereby improving the supporting strength of the fixed box 58.

[0035] like Figures 3 to 5 As shown, a support sleeve 10 is fixedly connected to the left side of the bottom of the inner wall of the fixed box 58, and the support sleeve 10 is slidably sleeved on the surface of the bevel gear rod 5102. The three water inlet ends of the four-way drainage pipe 511 are respectively connected to the top sleeve 3, the support sleeve 52 and the water tank 1.

[0036] Specifically, by providing the support sleeve 10, the bevel gear rod 5102 can be supported, thereby improving the stability of the bevel gear rod 5102 during rotation and preventing the bevel gear rod 5102 from shaking during rotation.

[0037] like Figures 3 to 5 As shown, a sealing ring 11 is fixedly connected to the bottom of the inner wall of the water tank 1, and the inner wall of the sealing ring 11 contacts the surface of the cross-conical gear tube 593. A sealing ring 2 12 is fixedly connected to the left side of the inner wall of the fixed box 58, and the inner wall of the sealing ring 2 12 contacts the surface of the conical gear rod 5102.

[0038] Specifically, by providing the sealing ring 11 and the sealing ring 2 12, the water tank 1 and the fixed box 58 can be sealed to prevent water from flowing out through the gaps, thereby improving the sealing performance.

[0039] The working principle and use process of the present invention: First, water is injected into the top sleeve 3 through the water inlet pipe 4. The water rotates and flows inside the top sleeve 3. The metal filter cartridge 51 performs preliminary filtration on the water. The filtered water enters the support sleeve 52. The intermediate filter cartridge 53 performs secondary filtration on the water. The filtered water enters the water tank 1. The high-level filter cartridge 57 performs tertiary filtration on the water. The filtered water is discharged through the drainage pump 2 for water supply, thus achieving a multi-stage filtration effect. When cleaning is required, the handle of the three-way valve pipe 591 is rotated to connect the drain pump 2 with the fixed box 58 through the three-way valve pipe 591. The drain pump 2 injects the water retained in the water tank 1 into the fixed box 58. The water flow pressure pushes the pad 5951 to compress the spring 5952. When the sealing plate 5954 moves to a suitable position, the water will enter the flushing pipe 594, the long tapered tooth pipe 592 and the cross tapered tooth pipe 593. The flushing pipe 594, the long tapered tooth pipe 592 and the cross tapered tooth pipe 593 spray water to respectively reversely flush the intermediate filter cartridge 53, the metal filter cartridge 51 and the high-grade filter cartridge 57 to discharge the impurities blocked therein. At the same time, the motor 5101 is started, and the motor 5101 drives the bevel gear rod 5102 to rotate. The bevel gear rod 5102 drives the long bevel gear tube 592 and the cross bevel gear tube 593 to rotate. The long bevel gear tube 592 drives the spiral scraper 5103 and the intermediate filter cartridge 53 to rotate. The spiral scraper 5103 scrapes off impurities on the surface of the metal filter cartridge 51. At the same time, the rotation of the intermediate filter cartridge 53 can throw out impurities, and the flushing pipe 594 can fully flush it. The cross bevel gear tube 593 drives the rotating sleeve 55 to rotate. Since the rotating gear ring 56 is engaged with the surface gear ring 5104, the high-grade filter cartridge 57 will rotate during rotation, and the high-grade filter cartridge 57 will throw off impurities. At the same time, the cross bevel gear tube 593 fully flushes the high-grade filter cartridge 57. When the cross bevel gear tube 593 rotates, it will drive the bevel gear 72 to rotate through the reducer 71, and the bevel gear 72 will drive the bevel gear cylinder 74 to rotate. At this time, the bevel gear cylinder 74 will push the slide rod 77 to move upward through the Z-shaped ring groove 76. The slide rod 77 drives the clamping plate 782 to move upward through the sliding sleeve 75 and the mouth-shaped sleeve 781, so that the sewage can be quickly discharged through the four-way drainage pipe 511. The sewage discharge process does not require manual intervention.
