Description

[0002] Urban sewage refers to wastewater generated by urban residents' lives, industrial production and commercial activities, mainly including organic matter, inorganic salts, suspended solids and microorganisms. In order to protect the environment, prevent the spread of diseases and improve the utilization rate of water resources, sewage generally needs to be filtered and purified by filtering and purification equipment before it is discharged.

[0003] Existing urban sewage filtration and purification equipment includes a purified water tank, the top of which is fixedly connected to a closed box, and the top of the inner cavity of the purified water tank is fixedly connected to a sewage particle isolation mesh plate. Through the coordinated use of zeolite, activated carbon particles and reverse osmosis membranes, zeolite is used to absorb and treat heavy metal ions in sewage, which is not only beneficial to the recycling of heavy metal ions, but also improves water quality. At the same time, the physical adsorption, photochemical adsorption, oxidation, catalytic oxidation and reduction properties of activated carbon particles are used to remove various pollutants in wastewater, thereby improving water quality. The reverse osmosis membrane is used to perform final treatment on sewage, and fine pollutants in the sewage are isolated to purify the sewage.

[0004] Although the existing equipment can achieve multi-stage filtration and purification of sewage, because its filtering and purification screens are fixed, as the use time increases, impurities in the sewage can easily and quickly clog these screens, thereby reducing the filtering and purification efficiency of the equipment.

[0053] A drain pipe 800 is disposed inside the first filter cartridge 410, and drain holes 810 are distributed on the outer wall of the drain pipe 800. One end of the drain pipe 800 extends outside the first filter cartridge 410 and is fixedly connected to the left connecting frame 210. One end of the drain pipe 800 cooperates with the water inlet pipe 300 fixed on the left bracket 200.

[0054] The rotary control mechanism 600 includes a transmission assembly 610, a control block 620, a rotary control assembly 630 and a connecting tube 640. The transmission assembly 610 is installed on one side of the right bracket 500. The transmission assembly 610 is connected to a driving mechanism 700 fixed on one side of the equipment seat 100. Two control blocks 620 are symmetrically fixed at both ends of the transmission assembly 610. The two control blocks 620 rotate in opposite directions, and the inner walls of the two control blocks 620 are circumferentially equidistantly provided with card grooves 621. A connecting tube 640 is fixed at one end of the transmission assembly 610. The connecting tube 640 is concentrically and fixedly connected to the right connecting frame 510. The rotary control assembly 630 is rotatably installed in the transmission assembly 610. One end of the rotary control assembly 630 intermittently cooperates with the card grooves 621 on the two control blocks 620. The other end of the rotary control assembly 630 extends into the first filter cartridge 410 and is concentrically and fixedly connected to the other end of the drain pipe 800.

[0055] The driving mechanism 700 drives both ends of the transmission assembly 610 to rotate in opposite directions. The transmission assembly 610 drives the two control blocks 620 and the connecting cylinder 640 to rotate at the same time. The connecting cylinder 640 and one control block 620 rotate clockwise, and the other control block 620 rotates counterclockwise. The connecting cylinder 640 drives the second filter cylinder 420 and the second purification cylinder 440 to rotate clockwise through the right connecting frame 510.

[0056] When the slot 621 on the control block 620 that rotates in the same direction as the connecting cylinder 640 cooperates with the rotary control assembly 630, the slot 621 on the control block 620 that rotates in the opposite direction to the connecting cylinder 640 separates from the rotary control assembly 630, and the control block 620 that rotates in the same direction as the connecting cylinder 640 drives the rotary control assembly 630 to rotate clockwise, and the rotary control assembly 630 drives the left connecting frame 210 to rotate clockwise through the drain pipe 800, and the left connecting frame 210 drives the first filter cartridge 410 and the first purification cartridge 430 to rotate clockwise, so that the first filter cartridge 410 , the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440 all rotate in the same direction. This synchronous and same-direction rotation can help maintain the stability of the sewage in the first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440, so that the particulate matter inside can be effectively settled and separated, so that the sewage can smoothly pass through the first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440 in sequence, completing the filtration and purification of the sewage;

[0057] When the rotary control assembly 630 cooperates with the control block 620 that rotates counterclockwise, the rotary control assembly 630 is separated from the control block 620 that rotates clockwise, and the control block 620 that rotates counterclockwise drives the rotary control assembly 630 to rotate counterclockwise through the slot 621. The rotary control assembly 630 drives the left connecting frame 210 to rotate counterclockwise through the drain pipe 800, and the left connecting frame 210 drives the first filter cartridge 410 and the first purification cartridge 430 to rotate counterclockwise, while the second filter cartridge 420 and the second purification cartridge 440 always rotate clockwise. This rotation method can generate a strong shear force between the two adjacent cylinders, and this shear force helps to reduce the surface of the filter purification assembly 400. The attached sediments make it difficult for the filter purification component 400 to be clogged, and the clogs generated when the filter purification component 400 rotates in the same direction and synchronously can be cleared, thereby extending the service life of the filter purification component 400, effectively removing suspended solids and impurities in sewage, and improving the efficiency and quality of the equipment in filtering and purifying sewage; at the same time, this rotation in different directions can help optimize the distribution of water flow between the cylinders, making the water flow more uniform, which is conducive to the sedimentation and separation of particulate matter, avoiding dead zones in the water flow, ensuring that the water flow in all areas can be effectively treated, and can reduce the mechanical stress concentration that may be caused by rotation in a single direction, thereby improving the overall stability of the equipment.

[0073] The working principle of the present invention is:

[0074] The driving motor 710 drives the main shaft 720 to rotate counterclockwise, and the main shaft 720 drives the bevel gear B613 to rotate counterclockwise through the transmission member 730. The bevel gear B613 drives the bevel gear C614 to rotate clockwise through the bevel gear A612, and the bevel gear B613 drives the control block 620 thereon to rotate counterclockwise, and the bevel gear C614 drives the control block 620 and the connecting cylinder 640 thereon to rotate clockwise. The connecting cylinder 640 drives the second filter cylinder 420 and the second purification cylinder 440 to rotate clockwise through the right connecting frame 510. The magnetic attraction member A634 and the magnetic attraction member B635 in the power-on state repel each other with the same polarity, so that the magnetic attraction member B635 drives the moving column 636 to move in the fixed cylinder 633 and squeeze the spring 637, and the moving column 636 drives the engaging member 638 to move to a position matched with the card slot 621;

[0075] When the slot 621 on the clockwise rotating control block 620 cooperates with a snap-fitting piece 638, the other snap-fitting piece 638 is separated from the counterclockwise rotating slot 621 under the drive of the spring 637, and the clockwise rotating control block 620 can drive the moving column 636 to rotate clockwise through the snap-fitting piece 638, and the moving column 636 drives the rotating shaft 631 to rotate clockwise through the fixed cylinder 633 and the fixed sleeve 632, and the rotating shaft 631 drives the left connecting frame 210 to rotate clockwise through the drain pipe 800, and the left connecting frame 210 drives the first filter cartridge 410 and the first purification cartridge 430 to rotate clockwise. The first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440 rotate clockwise, so that the first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440 all rotate in the same direction. This synchronous and same-direction rotation method can help maintain the stability of the sewage in the first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440, so that the particulate matter inside can be effectively settled and separated, so that the sewage can smoothly pass through the first filter cartridge 410, the second filter cartridge 420, the first purification cartridge 430 and the second purification cartridge 440 in sequence, thereby completing the filtration and purification of the sewage;

[0076] When the counterclockwise rotating slot 621 cooperates with a snap-fitting piece 638, the other snap-fitting piece 638 is separated from the clockwise rotating slot 621, and the counterclockwise rotating control block 620 drives the snap-fitting piece 638 to rotate counterclockwise, and the snap-fitting piece 638 drives the rotating shaft 631 to rotate clockwise through the movable column 636, the fixed cylinder 633 and the fixed sleeve 632, and the rotating shaft 631 drives the left connecting frame 210 to rotate counterclockwise through the drain pipe 800, and the left connecting frame 210 drives the first filter cylinder 410 and the first purification cylinder 430 to rotate counterclockwise, while the second filter cylinder 420 and the second purification cylinder 440 always rotate clockwise. This rotation method can allow the sewage to generate a strong shear force between the two adjacent cylinders. This shear force The force helps to reduce the sediment attached to the surface of the filter purification component 400, making the filter purification component 400 less prone to clogging problems, and can remove the blockages generated when the filter purification component 400 rotates in the same direction and synchronously, thereby extending the service life of the filter purification component 400, effectively removing suspended solids and impurities in sewage, and improving the efficiency and quality of the equipment in filtering and purifying sewage; at the same time, this rotation in different directions can help optimize the distribution of water flow between the cylinders, making the water flow more uniform, which is conducive to the sedimentation and separation of particulate matter, avoiding dead zones in the water flow, ensuring that the water flow in all areas can be effectively processed, and can reduce the mechanical stress concentration that may be caused by rotation in a single direction, thereby improving the overall stability of the equipment;

[0077] The above is the working principle of the city's sewage filtration and purification equipment.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
