Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering equipment, and in particular relates to an environmentally friendly filtration device for water conservancy projects. Background Technology

[0002] With the acceleration of industrialization and urbanization, the impact of human activities on water resources is gradually intensifying. Water pollution is becoming increasingly serious, especially due to the discharge of industrial wastewater, agricultural non-point source pollution, and domestic sewage. This results in water containing large amounts of harmful substances such as heavy metals, pesticides, fertilizers, suspended solids, and organic matter. These pollutants not only harm aquatic ecosystems but also affect water quality, threatening the safety of drinking water and agricultural irrigation water. Therefore, effective water quality protection measures are needed to ensure the sustainable use of water resources. Water conservancy projects play a crucial role in water resource management, including water source diversion, water supply, irrigation, and drainage. As water quality requirements increase, water conservancy projects must take effective measures to ensure the safety of water sources. Environmental filtration devices, as an important water treatment method, can effectively filter suspended solids, organic pollutants, and harmful substances in water, ensuring that water quality meets various usage requirements. Especially in water source protection projects such as reservoirs, lakes, and rivers, filtration devices can effectively remove pollutants and ensure the cleanliness of downstream water resources.

[0003] However, some environmental filtration devices used in water conservancy projects have relatively simple structures. They usually use rotating stirring blades inside the filtration device to agitate the water in the filter tube to promote filtration. However, as the stirring blades rotate, pollutants in the water may adhere to the rotating shaft of the stirring blades or accumulate in the dead corners of the filter tube, which increases the difficulty of subsequent cleaning and waste discharge. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly filtration device for water conservancy projects. By setting up a filtration mechanism, a first motor drives a rotating tube to rotate, which in turn drives several filter screens to rotate and stir the water flow. At the same time, several filter screens are set at an angle, which makes it easier for water with pollutants to come into contact with the filter screens more quickly. It is convenient to cooperate with the valve mechanism to complete the waste discharge and cleaning treatment. This solves the problem that when using a rotating stirring blade to promote filtration, pollutants may adhere to the rotating shaft of the stirring blade or accumulate in the dead corner of the stirring of the filter tube.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an environmentally friendly filtration device for water conservancy projects, including a housing, on which a filtration mechanism and a valve mechanism are provided:

[0007] The filtration mechanism includes a rotating component, a filtering component, and a scraping component. The rotating component includes a first motor fixedly connected to the inner wall of the housing. The output end of the first motor is fixedly connected to a first rotating shaft via a coupling.

The end of the linkage groove is fixedly connected to a first bevel gear. The inner wall of the linkage groove is rotatably connected to a second bevel gear, which meshes with the first bevel gear.

[0008] Furthermore, the filter assembly includes two limiting grooves formed on the inner wall of the outer shell, the inner walls of the two limiting grooves are rotatably connected to limiting rings, the inner walls of the two limiting rings are fixedly connected to rotating tubes, and the outer wall of the rotating tubes is rotatably connected to the inner wall of the outer shell.

[0009] Furthermore, the outer wall of the rotating tube is fixedly connected to the inner wall of the second bevel gear, a coarse filter screen is fixedly connected to the inner wall of the rotating tube, a fine filter screen is fixedly connected to the inner wall of the rotating tube, and an ultrafiltration screen is fixedly connected to the inner wall of the rotating tube.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is an environmentally friendly filtration device for water conservancy projects, including a housing 1, on which a filtration mechanism 2 and a valve mechanism 3 are provided:

[0028] The filtration mechanism 2 includes a rotating component, a filtering component, and a scraping component. The rotating component includes a first motor 21 fixedly connected to the inner wall of the housing 1. The output end of the first motor 21 is fixedly connected to a first rotating shaft 22 via a coupling. A linkage groove 23 is provided on the inner wall of the housing 1. The end of the first rotating shaft 22 extends to the inner wall of the linkage groove 23. A first bevel gear 24 is fixedly connected to the end of the linkage groove 23. A second bevel gear 25 is rotatably connected to the inner wall of the linkage groove 23. The second bevel gear 25 meshes with the first bevel gear 24.

[0029] Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the filter assembly includes two limiting grooves 26 formed on the inner wall of the outer casing 1. The inner walls of the two limiting grooves 26 are rotatably connected to limiting rings 27. The inner walls of the two limiting rings 27 are fixedly connected to rotating tubes 28. The outer wall of rotating tubes 28 is rotatably connected to the inner wall of the outer casing 1. The outer wall of rotating tubes 28 is fixedly connected to the inner wall of the second bevel gear 25. The inner wall of rotating tubes 28 is fixedly connected to a coarse filter screen 29, a fine filter screen 210, and an ultrafiltration screen 211. The scraping assembly includes a scraper frame 212 fixedly connected to the outer wall of rotating tubes 28. The top and bottom surfaces of the scraper frame 212 are rotatably connected to the inner wall of the outer casing 1. The outer wall of the outer casing 1 is fixedly connected to a first row of waste pipes 213.

[0030] By setting up the filtration mechanism 2, the first motor 21 drives the rotating tube 28 to rotate, which in turn drives several filter screens to rotate and stir the water flow. At the same time, several filter screens are tilted to facilitate water with pollutants to contact the filter screens more quickly, which speeds up the filtration efficiency of the device to a certain extent. Compared with the stirring blades to promote filtration, rotating the rotating tube 28 can make the water flow inside it more uniform, avoid dead corners, and facilitate the use of the valve mechanism 3 to complete the waste discharge and cleaning treatment, thus improving the practicality of the device.

[0031] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the valve mechanism 3 includes a waste discharge assembly and an inlet / outlet assembly. The waste discharge assembly includes a waterproof housing 31 fixedly connected to the outer wall of the rotating tube 28. A second motor 32 is fixedly connected to the inner wall of the waterproof housing 31. The output end of the second motor 32 is fixedly connected to a second rotating shaft 33 via a coupling. Several second waste discharge pipes 34 are fixedly connected to the outer wall of the rotating tube 28. The bottom end of the second rotating shaft 33 extends to the inner wall of the lower second waste discharge pipe 34. The outer wall of the second rotating shaft 33 is rotatably connected to the inner wall of several second waste discharge pipes 34. Sealing plates 35 are rotatably connected to the inner walls of several second waste discharge pipes 34. The inner wall of the second rotating shaft 33 is fixedly connected to the outer wall of several sealing plates 35. The inlet / outlet assembly includes an inlet 36 opened on the top surface of the housing 1 and an outlet 37 opened on the bottom surface of the housing 1. A fixing plate 38 is fixedly connected to the outer wall of the housing 1. Sealing valves 39 are provided on the inner walls of the fixing plate 38 and the outlet 37.

[0032] By setting up valve mechanism 3, the rotating tube 28 is sealed by sealing valve 39. In conjunction with the filtration mechanism 2, water flow is used to flush the inner wall of the rotating tube 28 and several filter screens. At the same time, the second motor 32 is driven to open several second waste discharge pipes 34. The accumulated pollutants are quickly thrown out by water. The pollutants inside the outer shell 1 are collected and cleaned by rotating scraper 212 and discharged through the first waste discharge pipe 213, thus completing the cleaning and waste discharge of the device and further improving the practicality of the device.

[0033] One specific application of this embodiment is as follows: The sealing valve 39 controls the flow or closure of fluid through the interaction between the valve's sealing element and the valve core and valve seat, thereby achieving the purpose of sealing the fluid. When it is necessary to stop the flow of fluid, the operator manually operates the valve to close it. During the closing process, the valve core begins to move closer to the valve seat, and the sealing surfaces gradually come into contact, ensuring that the sealing elements between the valve seat and the valve core are in full contact. After the valve core is completely closed, the sealing element and the valve seat form a tight contact to prevent fluid leakage. The valve is in a sealed state, and the fluid cannot pass through. When it is necessary to restore the flow of fluid, the operator manually operates the valve to open it. The valve core begins to move away from the valve seat, the fluid passage gradually opens, and the fluid begins to flow. The valve core or valve disc moves to the opening position, the sealing surfaces no longer come into contact, and the fluid can pass through the valve smoothly.

[0034] By setting up the filtration mechanism 2, when water enters the rotating tube 28 through the inlet 36, it drives the first motor 21, which in turn drives the first bevel gear 24 to rotate via the first rotating shaft 22. Since the first bevel gear 24 and the second bevel gear 25 mesh in the linkage groove 23, the first bevel gear 24 drives the second bevel gear 25 to rotate, and the second bevel gear 25 drives the rotating tube 28 to rotate within the outer casing 1. Two limiting grooves 26 and limiting rings 27 are provided at both ends of the rotating tube 28 to limit the rotation of the two ends of the rotating tube 28 within the outer casing 1. The rotation of the rotating tube 28 drives the coarse filter 29, fine filter 210, and ultrafiltration screen 211 inside it to rotate around the center of the device. The coarse filter 29, fine filter 210, and ultrafiltration screen 211 are set in an inclined state, which facilitates the rotation and stirring of the water containing pollutants in the rotating tube 28 by the inclined filter screens, while accelerating the contact of the water containing pollutants with the filter screens. The coarse filter 29 is used for preliminary removal of larger particulate pollutants in the water. The filtration process involves a fine filter 210 to filter smaller suspended solids such as silt, while an ultrafiltration screen 211 filters microorganisms or heavy metals. This multi-stage filtration reduces the workload of various filter screens compared to a single-stage filtration system, thus increasing filtration efficiency. The rotating tube 28 also simultaneously drives a scraper 212 to rotate within the outer casing 1. This, in conjunction with the valve mechanism 3, scrapes off and collects waste and impurities adhering to the inner wall of the casing 1, discharging the waste through the first waste pipe 213. This system utilizes the first motor 21 to drive the rotating tube 28, simultaneously rotating and agitating the water flow with several filter screens. The tilted arrangement of these screens allows water carrying contaminants to contact the screens more quickly, accelerating the filtration efficiency to some extent. Compared to the agitation of the stirring blades, which promotes filtration, the rotating tube 28 ensures more uniform water flow, avoiding dead zones and facilitating waste discharge and cleaning in conjunction with the valve mechanism 3, thus improving the practicality of the device.

[0035] By setting valve mechanism 3, when the filter mechanism 2 rotates the rotating tube 28 for filtration, if a certain amount of pollutants accumulate on the surface of several filter screens or inside the rotating tube 28, the outlet 37 is sealed by sealing valve 39, preventing the water inside the rotating tube 28 from flowing out. At this time, the second motor 32 drives several sealing plates 35 to rotate around the second rotating shaft 33 via the second rotating shaft 33, so that the second waste pipe 34 sealed by several sealing plates 35 connects the internal space of the outer shell 1 with the inside of the rotating tube 28 through the second waste pipe 34, so that the water in the rotating tube 28 contacts several coarse filter screens 29 and carries the pollutants or impurities on them out through several second waste pipes 34. At this time, the first motor 21 in the filter mechanism 2 continues to drive the rotating tube 28 to rotate, so that the water and pollutants in the rotating tube 28 flow smoothly. Centrifugal force propels the pollutants out through the second waste pipe 34, which then contact the inner wall of the outer casing 1. The rotating pipe 28 rotates, driving the scraper 212 to collect and clean the pollutants on the inner wall, facilitating the discharge of waste through the first waste pipe 213. The fixed plate 38 provides support for the outer casing 1 and facilitates the installation of the sealing valve 39. This allows the rotating pipe 28 to be sealed using the sealing valve 39. In conjunction with the filtration mechanism 2, water flow washes the inner wall of the rotating pipe 28 and several filter screens, while simultaneously driving the second motor 32 to open several second waste pipes 34. The water then quickly ejects the accumulated pollutants, which are then collected and cleaned by the rotating scraper 212 and discharged through the first waste pipe 213, completing the cleaning and waste removal process of the device and further improving its practicality.
