[0002] With the continuous increase in urban domestic sewage volume, the performance and efficiency of sewage treatment facilities face enormous challenges. To improve sewage treatment effectiveness, preliminary filtration is usually required before sewage enters the treatment facility. Filter cartridges are commonly used because they are easy and quick to clean, reducing manual maintenance workload and ensuring the smooth operation of the sewage filtration process.
[0003] Traditional filter cartridges work by drawing wastewater into the cartridge and filtering it through a screen inside the cartridge, blocking impurities from the water. However, cleaning commonly used filtration equipment is complex and inconvenient, often requiring manual removal of filter components, which is time-consuming and labor-intensive. This not only increases the consumption of manpower and resources but also reduces the working efficiency of the filter cartridge. Therefore, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-5A wastewater outlet filter cartridge for easy cleaning includes a cylinder body 1. A fixing bracket 7 is bolted to the outer side of the cylinder body 1. An end cap 2 is connected to the top of the cylinder body 1 via a flange. An inlet pipe 3 is welded to the top of the end cap 2. An outlet pipe 8 is welded to the bottom of the outer side of the cylinder body 1. A rotating shaft 16 is rotatably connected to the top of the end cap 2 via a bearing. Multiple filter screens 14 are bolted to the outer side of the rotating shaft 16. A fixing ring 15 is welded to the outer side of each filter screen 14. Multiple protrusions 17 are welded to the outer side of each fixing ring 15. A second ring 13 and two first rings 11 are bolted to the inner wall of the cylinder body 1. The inner walls of the second ring 13 and the two first rings 11 are each opened... There are second through grooves 22 corresponding to multiple protrusions 17. Multiple first sliding grooves 9 are opened inside the second ring 13 and the two first rings 11, and the protrusions 17 slide along the first sliding grooves 9. The cylinder 1 is provided with a shielding component to prevent sewage from leaking out of the second through groove 22. In use, the rotating shaft 16 drives multiple filter screens 14 to rotate, and at the same time the fixing ring 15 drives the protrusions 17 to slide along the first sliding grooves 9. When the protrusions 17 slide into the second through groove 22, the rotating shaft 16, its connected component and the protrusions 17 are pulled out of the second through groove 22, thereby disassembling the filter screens 14, which is convenient for subsequent cleaning, reduces the consumption of manpower and material resources, and reduces the impact of disassembly and cleaning on the working efficiency of the filter cylinder.
[0025] The shielding assembly includes a first baffle 10, which is slidably connected to a first ring 11 located above. Multiple connecting rods 21 are fixed to the bottom of the first baffle 10 by bolts. Two second baffles 12 are fixed to the outside of the multiple connecting rods 21 by bolts. Multiple through-type second sliding grooves 23 are opened on the top of the two first rings 11, and the connecting rods 21 slide in the second sliding grooves 23. The top of the first baffle 10 is provided with a drive assembly that makes the first baffle 10 rotate. In use, the first baffle 10 and the two second baffles 12 rotate to shield the second through groove 22, thereby preventing unfiltered sewage from entering the outlet pipe 8 through the second through groove 22, thus increasing the stability of the device during filtration.
[0026] The drive assembly includes a toothed ring 18, which is welded to the top of the first baffle 10. A fixed rod is rotatably connected to the outside of the cylinder 1, and a gear 19 is keyed to the outside of the fixed rod. The gear 19 meshes with the toothed ring 18. In use, rotating the gear 19 drives the toothed ring 18 to rotate, which in turn drives the first baffle 10 to rotate. The connecting rod 21 causes the two second baffles 12 to rotate as well, thereby increasing the filtration effect of the device.
[0027] This utility model features multiple first through slots 20 on the top of the first baffle 10 and the two second baffles 12, each corresponding to a protrusion 17. Both the first baffle 10 and the two second baffles 12 are annular, allowing the protrusion 17 to move out when aligned with the first through slot 20 and the second through slot 22, and to block the protrusion 17 when misaligned, thus increasing the device's convenience. A first handwheel 4 and a second handwheel 6 are welded to one end of the rotating shaft 16 and the fixing rod, respectively, allowing the rotating shaft 16 to be rotated via the first handwheel 4 and the second handwheel 6. The first handwheel 4 and the second handwheel 6 are rotated with the fixed rod to facilitate operation by the staff. The top of the first handwheel 4 and the second handwheel 6 are provided with threaded holes, and the tightening screws 5 are threaded into the two threaded holes. The tightening screws 5 can be tightened to make them contact the cylinder 1 or the end cover 2, thereby fixing the first handwheel 4 and the second handwheel 6. The multiple second through grooves 22 located in the second ring 13 are all welded with limit blocks 24. When installing the filter screen 14, the limit blocks 24 can limit the protrusion 17 to slide smoothly along the first slide groove 9.
[0028] Working principle: When sewage needs to be filtered, the sewage is connected to the inlet pipe 3. At this time, the sewage passes through multiple filter screens 14 for filtration, and the impurities in the sewage are filtered to one side of the filter screens 14. Then the filtered sewage is discharged through the outlet pipe 8. When the filter screens 14 need to be cleaned, the second handwheel 6 is turned, which causes the gear 19 to drive the toothed ring 18 to rotate, thereby causing the first baffle 10 and the two second baffles 12 to slide along the second slide groove 23, so that the first through groove 20 and the second through groove 22 are aligned. Then the first handwheel 4 is turned, which causes the rotating shaft 16 to drive the multiple filter screens 14 to rotate. At the same time, the fixing ring 15 drives the protrusion 17 to slide along the first slide groove 9. When the protrusion 17 slides into the second through groove 22, the rotating shaft 16, its connected components and the protrusion 17 are pulled out of the second through groove 22, thereby disassembling the filter screens 14 for easy subsequent cleaning, reducing the consumption of manpower and material resources, and reducing the impact of disassembly and cleaning on the working efficiency of the filter cartridge.
[0029] Furthermore, although embodiments of the present invention have been shown and described, 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.
