Description

Technical Field

[0001] This invention relates to the technical field of water pollution wastewater filtration, and more particularly to a high-efficiency filtration device for recycling and reusing construction wastewater pollution. Background Technology

[0002] Construction wastewater contains a large amount of silt, gravel, suspended impurities, and a small amount of chemical additives, resulting in turbid water with complex composition. Direct discharge not only wastes water resources but also causes water pollution, thereby contaminating soil and water bodies. Currently, the mainstream treatment methods in the industry mostly adopt extensive solutions of single filtration and simple sedimentation. Although some devices have added disinfection stages, the various treatment units lack coordinated design.

[0003] The filtration process often relies on single-layer filters, which struggle to remove impurities of varying sizes and easily clog the filter media, reducing treatment efficiency. Furthermore, the sedimentation, filtration, and disinfection processes are disconnected, leaving fine colloidal impurities and microorganisms unremoved. This results in effluent quality that fails to meet the recycling standards for construction water (such as concrete mixing and site spraying). In addition, existing systems are mostly modular, requiring large floor space and inconvenient maintenance, further limiting their widespread application in construction sites.

[0004] Therefore, there is an urgent need for a high-efficiency filtration device to solve the technical problems of poor coordination between processing units, incomplete filtration of water pollution, insufficient disinfection, and low wastewater recycling rate in existing technologies.

[0035] Example 1

[0036] Reference Figures 1-9 This first embodiment of the invention provides a high-efficiency filtration device for recycling and reusing construction wastewater. It mainly includes a recycling component 100, a filter housing 200, and a disinfection component. These three components work together to achieve rapid recycling, multi-stage precise filtration, and deep disinfection of construction wastewater. This specifically addresses the problems of construction wastewater containing silt, gravel, suspended impurities, turbidity, and strong odor, as well as the incomplete filtration, low efficiency, and difficulty in recycling of traditional filtration devices. Simultaneously, it considers structural stability and ease of maintenance, ensuring that the effluent quality meets construction water standards, achieving water resource recycling, and reducing construction water costs.

[0037] Furthermore, the recycling component 100 provides wastewater collection and transportation functions for the device. In this embodiment, the recycling component 100 includes a recycling tank 101, a liquid recycling pipeline 102 installed on the recycling tank 101, and an isolation tank 103 installed adjacent to the recycling tank 101. The recycling tank 101 is welded from corrosion-resistant steel plates, and the interior of the recycling tank 101 is treated with an anti-corrosion coating to withstand the erosion of mud, sand, and chemical agents in the construction wastewater. One end of the liquid recycling pipeline 102 is connected to the wastewater collection point of the construction site, and the other end is connected to the recycling tank 101. A filter screen is installed in the liquid recycling pipeline 102. The filter screen can perform pre-filtering and can initially intercept large particles of gravel, construction waste, and other large particulate impurities.

[0038] Furthermore, a recovery pump 104 is installed inside the recovery tank 101. The recovery pump 104 provides power for wastewater transportation. In this embodiment, a centrifugal pump is preferred, which can adapt to the transportation conditions of wastewater containing impurities. A recovery pipe 105 is connected to the recovery pump 104. A rotating column 106 is rotatably connected inside the recovery tank 101. The rotating column 106 is located in the center of the recovery tank 101 and is vertically arranged. One end of the recovery pipe 105 is connected to the outlet of the recovery pump 104. The other end passes through the end of the rotating column 106 and communicates with its internal cavity. Several spray holes 107 are evenly opened on the surface of the rotating column 106, and several liquid spray pipes 108 are fixedly connected to the outer periphery of the rotating column 106. The liquid spray pipes 108 are concave grooves and are inclined. After the recovery pump 104 is started, the wastewater enters the cavity of the rotating column 106 through the recovery pipe 105, and then is evenly sprayed into the recovery box 101 through the spray holes 107 and the liquid spray pipes 108.

[0039] Preferably, the rotating column 106 is driven to rotate by a motor, which is fixed to the outside of the recycling box 101. The rotation speed can be adjusted by the control system. Together with the inclined liquid spray pipe 108, a rotating spray effect is formed, which further enhances the mixing and dispersion effect of wastewater, reduces the deposition of impurities on the inner wall of the recycling box 101, and reduces the frequency of cleaning and maintenance.

[0040] Furthermore, the filter box 200 is the core unit for realizing wastewater purification. In this embodiment, the filter box 200 includes a sedimentation box 201 connected to the recovery box 101, a first filter assembly 202 disposed between the sedimentation box 201 and the recovery box 101, a sedimentation component 203 disposed on the first filter assembly 202, and a second filter assembly 204 disposed at the outlet of the sedimentation box 201. The sedimentation box 201 is connected to the isolation box 103.

[0041] Furthermore, the first filter assembly 202 performs the main filtration operation of wastewater. In this embodiment, the first filter assembly 202 includes a bracket 2021 connected to the flange of the recovery box 101, and a main filter frame 2022 fixed on the bracket 2021. The main filter frame 2022 has three conical structures and is fixedly connected to the bracket 2021. A main filter plate 2023 is provided on the main filter frame 2022. The overall structure of the main filter plate 2023 is circular and disc-shaped. An extension rod is provided on the side wall of the main filter plate 2023. The end of the extension rod is provided with a connecting block connected to the main filter frame 2022. The connecting block is connected to the main filter frame 2022 by bolts.

[0042] Preferably, the main filter plate 2023 is made of high-strength wear-resistant plastic material. Several bent filter strips 2024 are arranged in a circumferential array on the upper surface of the main filter plate 2023. The cross-sectional shape of each filter strip 2024 is semi-circular. In this embodiment, each filter strip 2024 is a filter block that is hinged end to end. Several filter holes are evenly opened on each filter strip 2024, with a preferred hole diameter of 1-3mm. The combination of the bent design and the circumferential array layout forms a wave-like shape, which guides the liquid as it flows downward. At the same time, the filter holes can accurately intercept large particulate impurities, preventing them from entering the sedimentation tank 201 and affecting the sedimentation effect.

[0043] Furthermore, a movable filter element 205 is movably connected to the support 2021. In this embodiment, the movable filter element 205 includes a filter cylinder 2051 rotatably connected to the main filter frame 2022, a lower pressure plate 2052 slidably connected inside the filter cylinder 2051, and a lower pressure rod 2053 disposed on the lower pressure plate 2052. The filter cylinder 2051 is cylindrical, and the lower pressure plate 2052 is disposed inside the filter cylinder 2051. The lower pressure plate 2052 can push the liquid downward to control the downward filtration rate of the liquid. An opening 2054 is opened at the lower end of the filter cylinder 2051, and a flexible annular edge is provided at the lower edge. The flexible annular edge is made of rubber. Thus, when the filter cylinder 2051 moves, the lower opening 2054 can fit tightly with the main filter plate 2023 to prevent wastewater from leaking out.

[0044] Preferably, an upper end frame 602 is provided on the filter cylinder 2051, a first bevel gear 603 is rotatably connected to the upper end frame 602, a pressure ring 604 is rotatably connected to the upper end frame 602, a second bevel gear 605 that meshes with the first bevel gear 603 is provided on the pressure ring 604, and the lower pressure rod 2053 is threadedly connected to the pressure ring 604.

[0045] Furthermore, several connecting pipes 2055 are opened on the filter cylinder 2051. The upper end of the connecting pipe 2055 is connected to the liquid recovery pipe 102, so that the liquid in the liquid recovery pipe 102 can be transported into the filter cylinder 2051. A floating filter element 300 is set in the filter cylinder 2051. With the up and down sliding of the lower pressure plate 2052, the filtration process can be dynamically adjusted.

[0046] Preferably, each main filter frame 2022 is equipped with a motor, a first drive arm 600 is connected to the output shaft of the motor, and a second drive arm 601 is rotatably connected to the first drive arm 600. Each second drive arm 601 is rotatably connected to the side wall of the filter cylinder 2051, and the driving direction of each motor is the same. Thus, the rotation of the three second drive arms 601 can be used to move the filter cylinder 2051 on the main filter plate 2023.

[0047] Furthermore, in this embodiment, the floating filter element 300 includes a main connecting ring 301, a plurality of filter rings 302, a flexible filter plate 303, and a support column 304. The main connecting ring 301 is disposed inside the filter cylinder 2051, and the inner wall of the filter cylinder 2051 is connected to the inner wall of the main connecting ring 301. The diameter of the plurality of filter rings 302 gradually increases from the support column 304 toward the main connecting ring 301. A gap is left between every two adjacent filter rings 302, and a filter screen is disposed in the gap. The lower end of each filter ring 302 is connected to a lower control rod 305.

[0048] Preferably, the lower end of the main connecting ring 301 extends out of the collection box 306, and a drain pipe 307 is provided on the collection box 306 to send water downward.

[0049] Furthermore, in this embodiment, the control component 400 includes a connecting post 401 disposed at the lower end of the filter cylinder 2051, a drive wheel 402 eccentrically connected to the connecting post 401, and a drive wheel 403 disposed at one end of the connecting post 401. The connecting post 401 is arranged horizontally, and a central ring extending upward from the center of the connecting post 401 is connected to the support post 304. Several drive wheels 402 are symmetrically arranged on both sides of the central ring, and the hinge positions of the drive wheels 402 on each side are different. A drive gear 40 is disposed on the outer periphery of the drive wheel 403. 4. Several drive teeth 405 that mesh with drive gear 404 are provided on the surface of the main filter plate 2023. The drive teeth 405 are arranged along the circular disk array of the main filter plate 2023, and the drive gear 404 meshes with the drive teeth 405 on the surface of the main filter plate 2023. When the drive wheel 403 rotates, it drives the connecting column 401 to rotate, thereby driving the eccentric rotation of several drive wheel bodies 402, thereby driving the lower control rod 305 to move up and down, and then driving several filter rings 302 to move up and down, thereby making the distance between each pair of filter rings 302 larger or smaller.

[0050] Furthermore, a slide bar 406 is provided at the lower end of each of the lower control rods 305, a slide groove 407 is provided on the drive wheel body 402 to cooperate with the slide bar 406, an annular groove 408 is provided on the slide groove 407, and a cooperating protrusion 409 protrudes from both ends of the slide bar 406 to cooperate with the annular groove 408.

[0051] Furthermore, several outer clamping rods 500 and inner clamping rods 501 are respectively provided on the two side walls of each filter ring 302. The outer clamping rods 500 and the inner clamping rods correspond one-to-one. A storage groove 502 is provided on the side wall of each outer clamping rod 500 and the inner clamping rod 501. Multiple winding cylinders 503 are provided in the storage groove 502. The multiple winding cylinders 503 are spaced at a predetermined interval. At the same time, the flexible filter plates 303 are respectively provided on the winding cylinders 503 in the storage groove 502. A pull rod 504 is provided on the side of the outer clamping rod 500 and the inner clamping rod 501 away from the storage groove 502. A matching clamping plate 505 connected to the pull rod 504 is provided on each of the flexible filter plates 303.

[0052] Furthermore, as the distance between the two filter rings 302 increases, the flexible filter plate 303 between the filter rings 302 expands accordingly. At the same time, the winding cylinder 503 on the outer clamping rod 500 and the inner clamping rod 501 releases the flexible filter plate 303, forming a multi-layer three-dimensional filtration structure to intercept fine suspended impurities.

[0053] Furthermore, a collection pipe 2026 is connected to the lower end of the main filter plate 2023. The collection pipe 2026 is located at the center of the main filter plate 2023. A funnel connected to the collection pipe 2026 is set on the lower surface of the main filter plate 2023. A cover plate is slidably connected to the filter strip 2024. The cover plate has secondary filter holes with a smaller diameter than the filter holes of the filter strip 2024. The position of the cover plate can be adjusted according to the impurity content of the wastewater to switch the filtration precision and adapt to the filtration needs under different working conditions.

[0054] Furthermore, in this embodiment, the sedimentation component 203 achieves deep sedimentation of wastewater, removing fine silt and colloidal impurities. The sedimentation component 203 includes a sedimentation inner tank 2031 connected to the filter cylinder 2051, a catalytic filter tank 2032 connected to the sedimentation inner tank 2031, and a drain path pipe 2033 disposed on the sedimentation inner tank 2031 and the catalytic filter tank 2032. The drain path pipe 2033 is connected to the upper end of the sedimentation tank 201.

[0055] Working logic: Wastewater treated by the first filter component 202 enters the sedimentation tank 2031 and slowly permeates through the catalytic filter tank 2032. Fine impurities are adsorbed or coagulated and settle to the bottom of the sedimentation tank 2031. The upper clarified wastewater flows to the second filter component 204 through the drain path pipe 2033. A drain outlet is set at the bottom of the sedimentation tank 2031, which can be opened periodically to discharge the sediment, making maintenance convenient.

[0056] Furthermore, in this embodiment, the second filtration component 204 achieves fine adsorption of wastewater, removing odors, residual organic matter and trace impurities. The second filtration component 204 includes an activated carbon adsorption box 2041 disposed in the sedimentation box 201, and a disinfection component includes a filter membrane 2042 disposed in the activated carbon adsorption box 2041 and a disinfectant addition module. The activated carbon adsorption box 2041 is connected to the isolation box 103. After secondary sedimentation in the isolation box 103, the liquid is transported to the liquid usage end through the connecting pipeline.

[0057] Furthermore, the present invention also includes a disinfection component integrated within the isolation chamber 103. The disinfection component includes a filter membrane 2042 and a disinfectant addition module. The filter membrane 2042 is an ultrafiltration membrane, which can intercept residual bacteria and microorganisms in the water. The disinfectant addition module is connected to the interior of the isolation chamber 103 and can automatically adjust the amount of disinfectant added according to water quality monitoring data.

[0058] Furthermore, the isolation box 103 also has a secondary sedimentation function. After the wastewater is disinfected, the small amount of residual sediment will settle to the bottom of the box and be discharged regularly through the sewage pipe. A clean water outlet is set on the top of the box and connected to the connecting pipeline, which can transport the qualified wastewater to the construction water end.

[0059] Operation process: Start the recycling pump 104 of the recycling component 100. Wastewater from the construction site enters the recycling tank 101 through the liquid recycling pipeline 102. The motor drives the rotating column 106 to rotate. Wastewater is sprayed through the spray hole 107 of the rotating column 106 and the liquid spray pipe 108 to break up the clumps of impurities and distribute them evenly in the recycling tank 101.

[0060] The wastewater in the recovery tank 101 then flows to the first filter assembly 202 and enters the filter cylinder 2051. The pressure plate 2052 then presses down to control the amount of wastewater entering. At this time, the motor drives the first drive arm 600 to rotate, which in turn drives the second drive arm 601 to rotate, causing the filter cylinder 2051 to move on the main filter plate 2023. During this movement, the drive gear 404 meshes with the drive gear 405, thereby rotating the drive wheel 403, which in turn drives the connecting column 401 to rotate. The eccentric rotation of several drive wheels 402 causes the lower control rod 305 to move up and down, which in turn drives several filter rings 302 to move up and down, thus increasing or decreasing the distance between each pair of filter rings 302. When the distance between two filter rings 302 increases, the flexible filter plate 303 between the filter rings 302 expands accordingly. At the same time, the winding cylinder 503 on the outer clamping rod 500 and the inner clamping rod 501 releases the first filter plate and the second filter plate, forming a multi-layer three-dimensional filtration structure to intercept fine suspended impurities.

[0061] Then, the wastewater falls onto the main filter plate 2023, where the filter strips 2024 further intercept large particles of silt and suspended impurities. The impurities are collected and discharged into the sedimentation tank 201 via the collection pipe 2026. The wastewater enters the inner sedimentation tank 2031, where fine silt and colloidal impurities are agglomerated and settled through the adsorption and catalysis of the catalytic filter tank 2032. The clarified wastewater flows through the drain path pipe 2033 to the second filter component 204 for secondary sedimentation. Finally, the qualified wastewater is transported to the construction water end through the connecting pipeline, completing the recycling process.
