Description

Technical Field

[0001] This utility model relates to the field of municipal wastewater treatment technology, specifically a municipal wastewater collection and filtration system. Background Technology

[0002] Municipal wastewater treatment refers to the process of purifying urban domestic sewage, industrial wastewater and other urban drainage through a series of physical, chemical and biological methods to remove pollutants and ensure that the effluent meets discharge standards before being discharged into natural water bodies (such as rivers and lakes) or reused (such as for greening irrigation and municipal miscellaneous uses).

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219941939U) discloses a municipal building sewage collection and pretreatment device, comprising a movable base plate, a sediment collection box, and a sewage filter box. A connecting pipe is fixedly connected to the middle of one side of the sewage filter box, and a connecting sleeve is fitted on the connecting pipe. The end of the connecting sleeve away from the sewage filter box is fixedly connected to the sediment collection box. The sediment collection box is placed on top of the movable base plate, and a motor is fixedly installed on the other side of the sewage filter box. This utility model discloses a municipal building sewage collection and pretreatment device. The filter plate filters the sewage, and the filtered sewage is discharged through a drain pipe, reducing the pollution of the sewage to the environment. The motor drives the spiral auger to rotate, transporting sediment and other impurities to the sediment collection box for collection, thus completing the municipal building sewage collection and pretreatment, saving time and reducing labor. The sediment collection box is moved by the movable base plate, facilitating the transportation of sediment and other impurities.

[0004] Although the aforementioned patent separates large particles of silt from water by using components such as a filter box, auger, and sediment collection box, thereby reducing the workload of operators and improving the silt separation effect, municipal sewage is rich in various impurities, such as mud, plastic, and small stones. While this component can separate silt from water, it cannot effectively separate impurities smaller than the screen plate, which is very detrimental to improving the filtration effect of municipal sewage.

[0005] Therefore, this utility model provides a municipal sewage collection and filtration system to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a municipal sewage collection and filtration system, such as Figures 1-4 As shown, a municipal sewage collection and filtration system includes a filter box 1, and a filter assembly is installed inside the filter box 1.

[0027] The filter assembly includes a circulation pump 2 installed at the bottom of the filter box 1. The output end of the circulation pump 2 is fixedly connected to a filter cartridge 4 through a connecting pipe 3. The filter cartridge 4 is fixedly connected to the outer wall of the filter box 1. The inner wall of the filter cartridge 4 is respectively clamped with a filter plate 5 and activated carbon cotton 6. An air pump 7 is installed on the outer wall of the filter box 1. One of the output ends of the air pump 7 is fixedly connected to an air pipe 8, and the air pipe 8 is located inside the filter cartridge 4. An aeration stone 9 is fixedly sleeved at the end of the air pipe 8.

[0028] The filter assembly also includes an outlet pipe 10 installed on the outer wall of the filter cartridge 4. A flange is fixedly fitted on the outer wall of the outlet pipe 10. An aeration box 11 is installed at the inner bottom of the filter box 1. The input end of the aeration box 11 is fixedly connected to one of the output ends of the air pump 7 through a sealing pipe 12.

[0029] A rotating base 13 is fixedly connected to the inner wall of the filter box 1. A rotating roller 14 is rotatably connected to the inner wall of the rotating base 13. A cutting blade 15 is fixedly sleeved on the outer wall of the rotating roller 14.

[0030] The outer walls of the two rotating rollers 14 are connected by a belt 16. One of the rotating rollers 14 has a drive motor 17 coaxially driven at its end. The drive motor 17 is mounted on the outer wall of the filter box 1 via a mounting plate 18.

[0031] Specifically, the filter box 1, in conjunction with the filter components, can treat municipal sewage, improving the treatment effect and accelerating the treatment efficiency. The circulating pump 2, along with the connecting pipe 3 and filter cartridge 4, can pump the initially screened water into the filter cartridge 4. There, in conjunction with the air pump 7 and aeration stones 9, the water undergoes a second filtration through aeration. The air impact separates the water from small particulate impurities. The water is then drained from bottom to top via a top-down flow, where filter plates 5 and activated carbon cotton 6 further intercept impurities, improving the quality of the discharged water. The outlet pipe 10 and its outer flange facilitate a quick and stable connection to downstream treatment equipment, ensuring stable delivery. The air pump 7 can stably deliver compressed gas to the inside of the filter cartridge 4 through the air pipe 8. When the air pump 7 is working, its other output end will synchronously deliver compressed air to the inside of the aeration box 11 through the sealing pipe 12. The aeration box 11 is then used to aerate the water inside the filter box 1, preventing the deposition of small particulate impurities. When the filter box 1 is working, the drive motor 17 installed on its outer wall, together with the rotating roller 14, belt 16 and multiple cutting blades 15, can enter the water inside the filter box 1 to cut it, so that the large particulate impurities contained therein are quickly cut into small pieces. At the same time, it can also cut some solid waste, further improving the applicability of the device and avoiding the phenomenon of equipment failure caused by impurities clogging.

[0032] The inner wall of the filter box 1 is rotatably connected to the screen plate 20 via the rotating shaft 19. The side wall of the filter box 1 is provided with a discharge port 21 at one end corresponding to the screen plate 20. The outer wall of the filter box 1 is fixedly connected to the receiving box 22 at the location corresponding to the screen plate 20.

[0033] An indicator light 23 is fixedly connected to the outer wall of the filter box 1. There are multiple indicator lights 23. A monitoring instrument is installed on the outer wall of the filter box 1 below the indicator lights 23.

[0034] Specifically, the rotating shaft 19 and the sieve plate 20 on the inner wall of the filter box 1 can filter and intercept the cut impurities. Due to the inclined setting, the impurities can be discharged into the receiving box 22 through the discharge port 21 by the impact of the water flow and their own weight, and then the impurities are collected in a unified manner. The display light 23 and monitoring instruments on the outer wall of the filter box 1 can facilitate the operator to monitor the filtration process in real time and ensure the safety of filtration.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
