Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a modular filter oil-water separation and slag removal structure for wastewater pipelines. Background Technology

[0002] With the rapid advancement of industrialization and urbanization worldwide, human society has achieved unprecedented economic progress and improved living standards. However, it also faces increasingly severe water shortages and water pollution problems. The expansion of industrial production, the high concentration of population during urbanization, and the modernization of agricultural activities have all led to a sharp increase in the demand for water resources, far exceeding the renewable capacity of the natural water cycle. This has resulted in a tense situation of water supply falling short of demand in many regions, especially in arid and semi-arid areas, where the scarcity of water resources is even more prominent, seriously affecting the satisfaction of agricultural irrigation, residential water use, and industrial production needs.

[0003] If untreated sewage is directly discharged into the environment during the maintenance or operation of sewage pipes, this practice will bring a series of serious environmental and ecological problems. Specifically, if the particulate matter, grease and various impurities contained in the sewage are discharged directly without proper pretreatment steps such as filtration, oil separation and sludge removal, it will directly lead to a significant deterioration of water quality.

[0004] First, particulate matter in wastewater includes suspended solids, silt, etc., which significantly reduce the transparency of water bodies and affect their aesthetics. More importantly, these particulate matter can also provide a substrate for microorganisms to attach to, promote the formation of biofilms, and thus accelerate the eutrophication process of water bodies, leading to excessive algal growth, consuming dissolved oxygen in the water, deteriorating water quality, and affecting the survival of aquatic organisms.

[0005] Secondly, oily pollutants form an oil film on the water surface, hindering oxygen from entering the water and making it difficult for aquatic organisms to survive due to lack of oxygen. At the same time, oil can also adhere to the surface of aquatic organisms, affecting their breathing and foraging, and even causing poisoning. In addition, oil is difficult to degrade in the environment, easily accumulates, and causes long-term harm to the ecosystem.

[0006] Therefore, there is an urgent need for a modular filtration, oil separation, and sludge removal structure for sewage pipelines to solve the above problems. Utility Model Content

[0011] Preferably, an oil-blocking module is provided on one side of the pipeline. The oil-blocking module includes a motor located at the front of the pipeline. The output shaft of the motor is fixedly connected to a drive pulley. A driven pulley is rotatably connected to one side of the front surface of the pipeline. The driven pulley and the drive pulley are connected by a belt drive. One side of each of the drive pulley and the driven pulley extends into the inner cavity of the pipeline and is respectively fixedly connected to an oil scraping structure one and an oil scraping structure two. The rear sides of the oil scraping structure one and the oil scraping structure two are rotatably connected to the pipeline. A filter box two is fixedly connected to the right side of the bottom of the pipeline inner cavity. The inner cavity of the filter box two is filled with a glass fiber filter element and a pleated filter element from left to right. An oil collection tank is fixedly connected to the top of the filter box two. A drain pipe two is connected to the right side of the pipeline. The drain pipe two is used in conjunction with the oil collection tank. A connecting pipe is connected to the bottom of the right side of the pipeline.

[0012] Furthermore, as a preferred embodiment of this utility model, control valve one and control valve two are respectively fitted onto the surfaces of the first sewage pipe and the second sewage pipe.

In actual use, the built-in solid interception plate serves as the first line of defense, which can initially intercept solid particles carried in sewage. Under the action of gravity, the solid particles will fall into the inner cavity of the storage tube. Then, the sewage passes through the filtration module, which can finely filter out small impurities, silt, and other suspended solids in the water, purifying the water quality. Next, as the sewage passes through the filtration module, the oil components will naturally float to the surface because their density is less than that of water. At this time, an oil interception module is provided, which, in conjunction with the oil scraping structure, removes oil and oil. With the rotation of Structure Two, the grease layer on the water surface is gently and effectively scraped and transferred to the oil collection tank.

[0025] As attached Figure 1 To be continued Figure 3 As shown: This embodiment provides a modular filter oil-water separation and slag removal structure for sewage pipelines, including: a pipeline 1, a storage pipe 2 extending through the left side of the bottom surface of the pipeline 1, a sewage discharge pipe 3 connected to the bottom of the storage pipe 2, a solid intercepting plate 4 fixedly connected to the left side of the top of the inner cavity of the pipeline 1, a fixing plate 5 fixedly connected to the left side of the bottom of the inner cavity of the pipeline 1 and located to the right of the storage pipe 2, and a filter module 6 provided in the inner cavity of the pipeline 1, the filter module 6 being located to the right of the fixing plate 5.

[0026] The filter module 6 includes a filter box 61 located inside the pipe 1. The inner cavity of the filter box 61 is filled from left to right with a metal powder filter element 62, a ceramic filter element 63 and an activated carbon filter element 64. The top of the filter box 61 extends through to the top of the pipe 1.

[0027] The inner cavity of filter box 61 is provided with a disassembly module 7. The disassembly module 7 includes a T-shaped block 71 fixedly connected to the inner wall of filter box 61. Two symmetrically arranged wedge blocks 72 are slidably connected to the surface of the T-shaped block 71. A spring 73 is fixedly connected to one side of the inner cavity of the wedge block 72. One end of the spring 73 is fixedly connected to the T-shaped block 71. Sliding holes 74 are provided on both sides of the top of filter box 61. An operating block 75 is slidably connected to the inner cavity of the sliding hole 74. The bottom of the operating block 75 is fixedly connected to the wedge block 72. The inner wall of the pipe 1 is provided with a groove 76 that matches the wedge block 72.

[0028] In the above embodiment, an oil-blocking module 8 is provided on one side of the pipe 1. The oil-blocking module 8 includes a motor 81 located at the front of the pipe 1. The output shaft of the motor 81 is fixedly connected to a drive pulley 82. A driven pulley 83 is rotatably connected to one side of the front surface of the pipe 1. The driven pulley 83 and the drive pulley 82 are connected by belt drive. One side of the drive pulley 82 and the driven pulley 83 extends into the inner cavity of the pipe 1 and is respectively fixedly connected to an oil scraping structure 1 84 and an oil scraping structure 2 85. The rear side of the oil scraping structure 1 84 and the oil scraping structure 2 85 is rotatably connected to the pipe 1. A filter box 2 86 is fixedly connected to the right side of the bottom of the inner cavity of the pipe 1. The inner cavity of the filter box 2 86 is filled with a glass fiber filter element 87 and a pleated filter element 88 from left to right. An oil collection tank 89 is fixedly connected to the top of the filter box 2 86. A drain pipe 2 810 is connected to the right side of the pipe 1. The drain pipe 2 810 is used in conjunction with the oil collection tank 89. A connecting pipe 9 is connected to the bottom of the right side of the pipe 1.

[0029] Specifically, control valve 10 and control valve 21 are respectively fitted onto the surfaces of sewage pipe 13 and sewage pipe 2810.

[0030] In this embodiment, the combined use of control valve 10 and control valve 21 controls the opening and closing of sewage pipe 3 and sewage pipe 2 810, thereby improving the rationality of the structural layout.

[0031] Specifically, a sealing gasket 12 is fixedly connected to the bottom of the filter box 61. The sealing gasket 12 is embedded in the bottom of the inner cavity of the pipe 1. A sealing ring 13 is provided on the surface of the filter box 61. The top of the sealing ring 13 is fixedly connected to the pipe 1.

[0032] In this embodiment, the combined use of the sealing gasket 12 and the sealing ring 13 improves the sealing between the filter box 61 and the pipe 1, preventing sewage from passing through the gap between the pipe 1 and the filter module 6.

[0033] Specifically, a grease interception plate 14 is fixedly connected to the inner cavity of pipe 1, and the grease interception plate 14 is located between filter box 1 61 and filter box 2 86.

[0034] In this embodiment, the grease interception plate 14 is used to intercept the grease carried in the water. Due to the density difference between oil and water, the grease will float on the water. Under the interception of the grease interception plate 14, the water passes through the bottom of the grease interception plate 14, while the grease floats above the grease interception plate 14.

[0035] Specifically, an inclined surface 15 is provided on one side of the oil collection tank 89, and the inclined surface 15 is used in conjunction with the oil scraping structure 85.

[0036] In this embodiment, the inclined surface 15 facilitates the conveying of grease to the inner cavity of the conveying oil collection tank 89, thereby improving the efficiency of grease conveying.

[0037] Specifically, a mounting bracket 16 is fitted onto the surface of the motor 81, and one side of the mounting bracket 16 is fixedly connected to the pipe 1.

[0038] In this embodiment, the fixing frame 16 serves to support and position the motor 81, thereby improving the stability of the motor 81 during operation.

[0039] During operation, as wastewater flows through pipe 1, it first encounters the solid interception plate 4. The solid sediment it carries settles into the inner cavity of storage pipe 2 due to gravity. This sediment can then be easily discharged through drain pipe 3. After initial sedimentation, the wastewater continues to flow, passing through the bottom of the solid interception plate 4 and sequentially through metal powder filter element 62, ceramic filter element 63, and activated carbon filter element 64. The metal powder filter element 62, with its porous structure and large specific surface area, effectively intercepts impurities such as tiny particles, colloids, and even bacteria, laying a solid foundation for the purification of the Wei River. The basic components include: ceramic filter element 63, which, due to its unique material advantages, retains beneficial minerals in the water while effectively removing sediment, bacteria, rust, and other contaminants; it is non-clogging, has a long service life, and provides excellent filtration; it is also resistant to clogging and can withstand very poor water quality. Activated carbon filter element 64 integrates adsorption, filtration, interception, and catalysis, effectively removing organic matter, residual chlorine, and other radioactive substances from the water, and also has decolorizing and odor-removing effects. The filtered water flows out from the right side of filter box 61. At this point, due to the density difference between oil and water, the oil will float to the bottom of the water. To remove grease, a grease-blocking plate 14 is designed. When grease carried by the water encounters the grease-blocking plate 14, the grease is blocked and accumulates on the surface of the water. At this time, the motor 81 is started, and the output shaft of the motor 81 drives the drive pulley 82 to rotate. When the drive pulley 82 rotates, it drives the driven pulley 83 to rotate under the transmission of the belt. When the drive pulley 82 and the driven pulley 83 rotate, they respectively drive the first oil scraping structure 84 and the second oil scraping structure 85 to rotate. When the first oil scraping structure 84 and the second oil scraping structure 85 rotate, they can scrape the grease floating on the surface of the water into the oil collection tank 8. The grease is then discharged through the drain pipe 810 into the inner cavity of 9. After the grease is effectively removed, the water passes through the bottom of the grease interception plate 14 and is filtered by the glass fiber filter element 87 and the pleated filter element 88 to remove the remaining grease. First, the glass fiber filter element 87 effectively captures tiny oil particles with its excellent corrosion resistance and heat resistance. The pleated filter element 88, with its large filtration area and high filtration efficiency, can handle a large amount of oil and ensure that the water quality reaches a higher purification standard. Finally, after this series of treatments, the water is discharged through the connecting pipe 9.

[0040] Furthermore, after the oil-blocking module 8 has been used for a long time, the user can move the two operating blocks 75 relative to each other, so that the operating blocks 75 move in the inner cavity of the sliding hole 74, thereby driving the wedge block 72 to move on the surface of the T-shaped block 71. When the operating blocks 75 move, they will leave the inner cavity of the fixing frame 16 and compress the spring 73, so that the spring 73 is in a contracted state. When the wedge block 72 completely leaves the inner cavity of the slot 76, the filter module 6 can be moved upward, so as to disassemble the filter module 6 and facilitate the maintenance of the filter module 6.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
