Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, and in particular to an environmentally friendly water filter with circulating filtration. Background Technology

[0002] Environmental water recycling and filtration refers to the process of treating used wastewater (such as industrial wastewater and domestic sewage) to meet reuse standards and then recycling it. This process typically involves multiple treatment technologies, including physical, chemical, and biological methods, to remove pollutants such as suspended solids, organic matter, microorganisms, and heavy metals from the water, ensuring that the water quality meets the requirements for specific applications.

[0003] Currently, in the process of environmental water recycling and filtration, filters are often used to remove large particulate impurities from the water.

[0004] Existing water filtration equipment requires shutdown and filter removal when the filter screen becomes clogged or needs cleaning, causing filtration operations to be interrupted and affecting continuous operating efficiency. Furthermore, filter screen replacement is cumbersome, and frequent disassembly and reassembly can lead to a decline in sealing performance, affecting filtration effectiveness. Utility Model Content

[0005] This utility model is an environmentally friendly water filter with circulating filtration proposed to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly water filter with circulating filtration, comprising a shell, wherein a cylinder is rotatably connected to the inner surface of the shell, and T-shaped holes penetrating to the interior are provided at the top and bottom of the cylinder, and filter components are sealed and pressed into the two T-shaped holes.

[0007] Two arc-shaped pressure rods are sealed to the outer surface of the cylinder, and the arc-shaped pressure rods are fixedly embedded in the inner walls of both sides of the shell. The bottom of each of the two arc-shaped pressure rods is locked with a support rod, and the support rod matches the filter assembly.

[0008] Two through holes extending into the interior are symmetrically opened at one end of the cylinder;

[0009] A screw-type drive assembly is installed between the cylinder and the shell.

[0010] A water inlet pipe is fixedly connected to one side of the outer surface of the shell, and the water inlet pipe matches the through hole.

[0011] Furthermore, a water outlet pipe is fixedly connected to one side of the outer surface of the shell, and two support legs are symmetrically fixed to both sides of the outer surface of the shell. The water outlet pipe facilitates the discharge of filtered water.

[0012] Furthermore, both of the filter components include a frame, and the frame is sealed and fitted inside the T-shaped hole. A filter screen is fixedly installed on the inner surface of the frame. Two arc-shaped strips are fixedly connected to the inner walls on both sides of the frame, and the arc-shaped strips are fitted with adjacent arc-shaped pressure rods and support rods. This design makes the filter screen installation more stable, and the tight fit between the arc-shaped strips and the pressure rods and support rods effectively prevents the filter screen from loosening.

[0013] Furthermore, a locking screw is fixedly connected to one side of the outer surface of the two support rods, and the locking screw passes through the arc-shaped pressure rod and is rotatably connected to the arc-shaped pressure rod. A hand-tightening nut is threaded onto the outer surface of the locking screw, and the hand-tightening nut abuts against the arc-shaped pressure rod. This structure enables quick locking or loosening by hand-tightening the nut, simplifying the filter replacement process.

[0014] Furthermore, the screw-type drive assembly includes a gear, and the mounting shaft of the gear passes through the housing and is fixedly connected to the mounting shaft of the cylinder. A rack is meshed with the top of the gear, and the rack slides against the outer wall of the housing. This transmission method has a simple structure, stable operation, and can accurately control the rotation angle of the cylinder to ensure accurate filter switching.

[0015] Furthermore, a handwheel is provided on one side of the rack, and an adjusting screw is fixedly connected to one side of the outer surface of the handwheel. The rack is threaded onto the outer surface of the adjusting screw. By driving the adjusting screw to rotate through the handwheel, the rack can be easily moved, making the operation convenient and labor-saving.

[0016] Furthermore, a support seat is rotatably connected to the outer surface of the adjusting screw, and the support seat is fixedly connected to the housing. The support seat provides support for the adjusting screw, which facilitates the installation of the adjusting screw.

[0017] The beneficial effects of this utility model are:

[0018] In use, this utility model is an environmentally friendly water filter with circulating filtration. Through a rotatable cylinder and a dual-filter alternating operation design, it enables online filter switching, allowing filter replacement or cleaning without stopping the machine, ensuring continuous filtration. Simultaneously, it employs a T-hole sealing structure and a quick-assembly / disassembly structure combining an arc-shaped pressure rod, locking nut, and support rod, simplifying filter assembly and disassembly steps, improving maintenance convenience, and ensuring reliable sealing.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown, an environmentally friendly water filter with circulating filtration is disclosed, including a housing 1. A cylinder 6 is rotatably connected to the inner surface of the housing 1. The cylinder 6 adopts a dual-chamber design, with a separate top chamber and a bottom chamber. T-shaped holes 19 extending into the interior are provided at both the top and bottom of the cylinder 6. Filter components are sealed and pressed into both T-shaped holes 19. Both filter components include a frame 17, which is sealed and fitted into the T-shaped holes 19. A filter screen 7 is fixedly installed on the inner surface of the frame 17. Two arc-shaped strips 18 are fixedly connected to the inner walls on both sides of the frame 17.

[0029] Two arc-shaped pressure rods 5 are sealed to the outer surface of the cylinder 6, and the arc-shaped pressure rods 5 are fixedly embedded in the inner walls of both sides of the shell 1. The bottom of each arc-shaped pressure rod 5 is locked with a support rod 9, and the support rod 9 matches the filter assembly. The arc-shaped strip 18 fits against the adjacent arc-shaped pressure rod 5 and support rod 9. A locking screw 10 is fixedly connected to one side of the outer surface of the two support rods 9, and the locking screw 10 passes through the arc-shaped pressure rod 5 and is rotatably connected to the arc-shaped pressure rod 5. A hand-tightening nut 11 is threaded onto the outer surface of the locking screw 10, and the hand-tightening nut 11 abuts against the arc-shaped pressure rod 5. The hand-tightening nut 11 and the locking screw 10 cooperate to lock the support rod 9.

[0030] Two through holes 16 are symmetrically opened at one end of the cylinder 6, and sealing gaskets are attached to both sides of the cylinder 6. The sealing gaskets are fixedly connected to the shell 1 and the arc-shaped pressure rod 5. Annular sealing gaskets are also attached to both ends of the cylinder 6. The annular sealing gaskets are fixedly connected to the shell 1 and the sealing gasket. The annular sealing gaskets have round holes that match the adjacent through holes 16 and the water inlet pipe 2.

[0031] A screw-type drive assembly is installed between the cylinder 6 and the shell 1. The screw-type drive assembly includes a gear 4, and the mounting shaft of the gear 4 passes through the shell 1 and is fixedly connected to the mounting shaft of the cylinder 6. A rack 3 is meshed with the top of the gear 4, and the rack 3 slides against the outer wall of the shell 1. A handwheel 15 is provided on one side of the rack 3. An adjusting screw 13 is fixedly connected to one side of the outer surface of the handwheel 15, and the rack 3 is threaded onto the outer surface of the adjusting screw 13. A support seat 14 is rotatably connected to the outer surface of the adjusting screw 13, and the support seat 14 is fixedly connected to the shell 1. The thread helix angle of the adjusting screw 13 is smaller than the friction angle, so that the adjusting screw 13 has a self-locking ability and can prevent it from shifting due to vibration or load.

[0032] A water inlet pipe 2 is fixedly connected to one side of the outer surface of the housing 1, and the water inlet pipe 12 matches the through hole 16.

[0033] A water outlet pipe 12 is fixedly connected to one side of the outer surface of the shell 1. The water outlet pipe 12 can be connected to the pipeline of the next wastewater treatment process, which is conducive to the discharge of the filtered wastewater.

[0034] Two support legs 8 are symmetrically fixedly connected to both sides of the outer surface of the housing 1. The support legs 8 raise the overall height, which facilitates the replacement of the filter screen 7.

[0035] Working principle: Wastewater is transported to the inlet pipe 2 through the existing pumping equipment. The wastewater enters the top partition of the cylinder 6 through the through hole 16, and then enters the shell 1 after being filtered by the top filter screen 7. Finally, it is discharged through the outlet pipe 1.

[0036] When it is necessary to remove the filter screen 7 that is in use, turn the adjusting screw 13 by turning the handwheel 15. The adjusting screw 13 drives the rack 3 to move along the housing 1. When the rack 3 moves, it drives the gear 4 to rotate. The gear 4 drives the cylinder 6 to rotate, transferring the bottom filter screen 7 to the top and the filter screen 7 that needs to be replaced at the top to the bottom. Then loosen the two hand nuts 11, and the two support rods 9 will hang down naturally, releasing the limit on the filter assembly. Then the filter assembly can be removed.
