Abstract
Description
Technical Field
[0001] This utility model relates to an integrated device, specifically an integrated device for treating sewage in rural mountainous areas, belonging to the field of sewage treatment technology. Background Technology
[0002] Rural wastewater treatment in mountainous areas refers to a systematic project that collects, treats, and utilizes domestic sewage (such as kitchen, laundry, and toilet wastewater) in mountainous rural areas with complex terrain, sparse population, and weak infrastructure. This is done using decentralized or small-scale centralized treatment technologies suitable for local natural and economic conditions. The aim is to prevent the direct discharge of untreated sewage into mountainous soil, surface water, and groundwater, thereby ensuring the safety of the rural ecological environment, improving living sanitation conditions, and promoting the recycling of water resources.
[0003] A Chinese utility model patent (publication number: CN214457278U) discloses an intelligent small-scale integrated device for treating domestic sewage. It filters impurities through filter plates and then performs secondary sedimentation of sewage in a sedimentation tank, thereby treating sewage. At the same time, through the cooperation of structures such as chute, screw, groove, and turntable, the filter plates can be raised out of the filter box, which makes it easy to disassemble and clean the filter plates, thus improving applicability.
[0004] While this device achieves wastewater treatment and, to some extent, solves the problem of difficult maintenance of traditional fixed filter plates, the filter plate cleaning process still relies on manual operation. It requires manual disassembly, transport, rinsing, and repositioning of the filter plates, which not only has drawbacks such as cumbersome operation procedures, high labor intensity, and low cleaning efficiency, but also easily leads to filter plate damage or secondary pollution due to improper operation during manual cleaning. This makes it difficult to meet the actual needs of wastewater treatment scenarios in mountainous rural areas for automated, low-maintenance, and efficient operation. Therefore, an integrated wastewater treatment device for mountainous rural areas is proposed. Utility Model Content

Detailed Implementation
[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] Example
[0027] Please see Figures 1-5 This utility model provides a technical solution: an integrated sewage treatment device for rural mountainous areas, including a filter assembly 101, which includes a filter box 11, a guide pipe 12, a storage box 13, a filter plate 15, a linear module 16, a mounting base 19, a nozzle 20, a collection filter cartridge 22, a limiting ring 23, and a return pipe 24.
[0028] The top of the filter box 11 is equipped with a cover plate 17, and a sewage inlet pipe 18 is installed on the cover plate 17. The filter box 11 is connected to the top of the collection box 13 through the guide pipe 12, and is connected to the bottom of the collection box 13 through the return pipe 24. A removable filter screen (not shown in the figure) is installed in the return pipe 24 to intercept particulate matter in the return water again.
[0029] The filter plate 15 is installed at an angle inside the filter box 11, with the filter plate 15 forming an angle of 45°-60° with the horizontal plane.
[0030] The sewage inlet pipe 18 is used to transport rural sewage to the filter box 11. Then, under the filtration action of the filter plate 15, the particulate matter in the sewage is effectively filtered out. Since the filter plate 15 adopts an inclined design, some of the filtered particulate matter can flow smoothly into the guide pipe 12 along the filter plate 15 and finally enter the collection box 13.
[0031] The collection filter cartridge 22 is located inside the storage box 13, and its top is attached to the upper surface of the limiting ring 23. A rubber sealing ring is provided on the contact surface between the limiting ring 23 and the collection filter cartridge 22 to prevent sewage leakage.
[0032] The guide pipe 12 and the return pipe 24 are located above and below the collecting filter cartridge 22, respectively. The particles entering the collection box 13 flow into the collecting filter cartridge 22. At this time, the particles can be effectively collected through the collecting filter cartridge 22, while the water continues to drip and flows smoothly into the interior of the filter box 11 through the return pipe 24.
[0033] The limiting ring 23 is fixedly connected to the inner wall of the storage box 13. The position of the collection filter cartridge 22 can be limited by the limiting ring 23. After opening the top cover of the storage box 13, the collection filter cartridge 22 can be taken out directly, so as to facilitate unified cleaning.
[0034] The top of the collection filter cartridge 22 is equipped with a handle, which greatly facilitates its removal.
[0035] The linear module 16 is obliquely installed on the inner rear wall of the filter box 11. The mounting base 19 is installed on the slider of the linear module 16. The nozzles 20 are equidistantly installed on the outer side wall of the mounting base 19 and located above the filter plate 15. The spacing of the nozzles 20 is ≤ 1 / 3 of the width of the filter plate 15.
[0036] A water pump 25 is installed on the outer wall of the filter box 11. The linear module 16 and the filter plate 15 are parallel to each other. The outlet of the water pump 25 is connected to the nozzle 20 through a pipe. When the water pump 25 is working, the nozzle 20 sprays high-pressure water to rinse the filter plate 15.
[0037] The linear module 16 drives the mounting base 19 to move along the surface of the filter plate 15. The mounting base 19 drives the nozzle 20, which sprays water to effectively clean the particles on the surface of the filter plate 15. The cleaned particles flow into the collection filter cartridge 22 under the flushing of the water, while the water enters the filter box 11 through the return pipe 24. This achieves automatic cleaning of the filter plate 15. This process eliminates the tedious operation of manually disassembling, moving the filter plate and completing the flushing and resetting. The operator only needs to empty the particles in the collection filter cartridge 22 periodically. The operation is simple, the labor intensity is low, and the cleaning efficiency is high, which meets the actual needs of rural sewage treatment in mountainous areas for automated, low-maintenance and high-efficiency operation of equipment.
[0038] The linear module 16 adopts a dustproof and waterproof design. Both the linear module 16 and the water pump 25 are controlled by a controller (not shown in the figure) for timing, which further ensures the automatic cleaning effect of the filter plate 15.
[0039] In this utility model, the linear module 16, the water pump 25, and the controller are all existing technologies, so their internal structure, working principle, connection, and control method will not be described in detail.
[0040] In this embodiment, specifically: a dosing pipe 26 is installed on the upper side of the filter box 11. Water treatment agents can be added into the filter box 11 through the dosing pipe 26 to treat rural sewage. After the dosing, the sewage enters the sedimentation tank 31 through the conveying pipe 35.
[0041] The dosing tube 26 can be connected to an automatic dosing device (not shown in the figure) to achieve automatic dosing of the agent.
[0042] In this embodiment, specifically: a conveying pipe 35 and a sedimentation tank 31 are provided outside the filter box 11. The filter box 11 is connected to the sedimentation tank 31 through the conveying pipe 35. A circulation pump 34 is installed on the conveying pipe 35. A clear water outlet pipe 32 and a sedimentation outlet pipe 33 are respectively installed on the upper and lower parts of the front surface of the sedimentation tank 31. After filtration and chemical addition, the sewage flows into the sedimentation tank 31 for sedimentation under the conveying action of the circulation pump 34. During the sedimentation process, the upper clear water is discharged through the clear water outlet pipe 32, while the water containing sediment is discharged through the sedimentation outlet pipe 33.
[0043] Working principle or structural principle: In use, rural sewage is transported to the filter box 11 through the sewage inlet pipe 18. Under the filtration action of the filter plate 15, the particulate matter in the sewage is effectively filtered out. The particulate matter filtered out on the filter plate 15 can flow smoothly into the guide pipe 12 along the filter plate 15 and finally enter the collection box 13. The particulate matter in the collection box 13 then flows into the collection filter cylinder 22. At this time, the particulate matter can be effectively collected through the collection filter cylinder 22. At the same time, water continues to drip and flows smoothly into the interior of the filter box 11 through the return pipe 24. The chemical dosing pipe 26 automatically adds chemicals into the filter box 11. After filtration and chemical addition, the sewage flows into the sedimentation tank 31 for sedimentation under the transportation action of the circulation pump 34. During the sedimentation process, the upper clear water is discharged through the clear water outlet pipe 32, while the water containing sediment is discharged through the sedimentation outlet pipe 33.
[0044] During this process, the linear module 16 and the water pump 25 are started at regular intervals. The linear module 16 drives the mounting base 19 to move along the surface of the filter plate 15. The mounting base 19 drives the nozzle 20, which sprays water to effectively clean the particles on the surface of the filter plate 15. The cleaned particles flow into the collection filter cartridge 22 along the surface of the filter plate 15 under the flushing of the water flow, while the water enters the filter box 11 through the return pipe 24, thus realizing the automatic cleaning of the filter plate 15.
[0045] Compared with existing technologies, this utility model achieves automatic cleaning of the filter plate 15 through the cooperation of the linear module 16, mounting base 19, nozzle 20, water pump 25 and other structures. This eliminates the tedious operation of manually disassembling, moving the filter plate and completing the rinsing and resetting. Operators only need to periodically empty the particulate matter in the collection filter cartridge 22. The operation is simple, the labor intensity is low, and the cleaning efficiency is high, which meets the actual needs of rural sewage treatment in mountainous areas for automated, low-maintenance and high-efficiency operation of equipment.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
