Description

Technical Field

[0001] This utility model discloses a pipeline filtration device, belonging to the field of water conservancy pipeline technology. Background Technology

[0002] During the water transport process in the pipeline network, trace amounts of silt, rust, and other particles may be carried. As a result, a large amount of impurities accumulate in the secondary water supply container over a long period of time. When the secondary water supply is activated, these impurities will enter the user end with the water flow. Therefore, a filter device needs to be installed at the outlet pipe of the secondary water supply container to prevent impurities from entering the user end with the water flow.

[0003] Currently, conventional fixed filtration structures, due to their static filtration mode, cause impurities to continuously accumulate on the flow-facing side of the filter screen, failing to effectively disperse or remove them. This easily leads to partial or even complete clogging of the filter screen, significantly reducing filtration efficiency and water flow. Furthermore, the single-piece filter screen design lacks structural strength under continuous water flow impact, especially when facing pressure fluctuations or peak flow rates, making it prone to plastic deformation or breakage. This not only weakens the filtration effect but may also allow impurities to penetrate due to filter screen failure. Summary of the Invention

[0004] This utility model overcomes the shortcomings of the prior art and proposes a pipeline filtration device, including: a main pipe, a filter barrel, a drive mechanism, an inlet pipe and an outlet pipe; The filter barrel is coaxially rotatably disposed in the main tube, and multiple filter holes are arranged on its periphery. The drive mechanism is connected to the filter barrel and is used to drive the filter barrel to rotate around its own axis; The inlet pipe is connected to the side wall of the main body, and its outlet faces the side surface of the filter bucket. The water outlet pipe is connected to the inner cavity of the filter bucket.

[0005] Preferably, the drive mechanism includes turbine blades and a transmission assembly; The turbine blades are disposed inside the water inlet pipe; The transmission assembly connects the turbine blades and the filter barrel.

[0006] Preferably, the transmission assembly includes a first rotating shaft, a second rotating shaft, a first gear, and a second gear; One end of the first rotating shaft is fixedly connected to the turbine blade, and the other end passes through the top wall of the water inlet pipe and is fixedly connected to the first gear. One end of the second rotating shaft is fixedly connected to the filter barrel, and the other end passes through the top wall of the main body and is fixedly connected to the second gear; The first gear and the second gear mesh.

[0007] Preferably, the first gear is an incomplete gear.

[0008] Preferably, it also includes a scraper assembly; The scraper assembly is disposed on the inner wall of the main body, and the working end of the scraper assembly is elastically pressed against the side surface of the filter barrel.

[0009] Preferably, the working end of the scraper assembly is a scraper or a bristle brush.

[0010] Preferably, it also includes an impurity collection unit; The impurity collection unit is detachably mounted at the bottom of the main body.

[0011] Preferably, a first shaft seal assembly is provided between the first rotating shaft and the top wall of the water inlet pipe; A second shaft seal assembly is provided between the second rotating shaft and the top wall of the main body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses water flow to impact turbine blades, which drives the filter barrel to rotate, avoiding the problem of decreased filtration efficiency caused by the accumulation of debris on one side of the traditional fixed filter barrel. This allows the debris to be evenly distributed on the surface of the filter barrel, extending the effective filtration time. It effectively prevents sediment and fine pollutants in the secondary water supply container from entering the user end with the water flow. In addition, the impurity collection unit is easy to clean and maintain, providing the last line of defense for users' water use.

[0013] By intermittently meshing the incomplete gear with the second gear to rotate the gear, the filter barrel is driven to rotate intermittently. This ensures that the filter barrel receives rotational power while avoiding energy loss and component wear caused by excessive continuous rotation.

[0014] In this invention, when water flows through the filter barrel, impurities are trapped on the outer wall of the filter barrel, and the filtered water is discharged from the outlet pipe. Simultaneously, a scraper assembly fixed to the inner wall of the main pipe adheres to the outer surface of the filter barrel, continuously scraping away the attached impurities as the filter barrel rotates. The impurities fall into the impurity collection container, reducing the frequency of manual cleaning, lowering maintenance costs, and effectively preventing pipe blockage. The impurity collection container is detachably located at the bottom of the main pipe, facilitating easy removal and cleaning of the impurities inside. Attached Figure Description

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1-4 As shown, the purpose of this embodiment is to provide a pipeline filtration device, including: a main pipe body 1, a filter barrel 3, a drive mechanism, an inlet pipe 2, and an outlet pipe 4; The filter barrel 3 is coaxially rotatably installed inside the main body 1, and multiple filter holes are arranged around its periphery. The drive mechanism is connected to the filter barrel 3 and is used to drive the filter barrel 3 to rotate around its own axis; The inlet pipe 2 is connected to the side wall of the main pipe 1, and its outlet faces the side surface of the filter bucket 3. The water outlet pipe 4 is connected to the inner cavity of the filter bucket 3.

[0019] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the water outlet pipe 4 has an L-shaped structure, with its horizontal end penetrating through the side wall of the main pipe body 1 and its vertical end extending to the bottom of the filter bucket 3. The water inlet pipe 2 is horizontal, penetrating through the side wall of the main pipe body 1, and its outlet faces the side wall of the filter bucket 3.

[0020] Specifically, the rotating filter barrel 3 of this utility model can be rotated by electric drive, or by setting guide vanes on the outer surface of the filter barrel 3, and the incoming water flow impacts the vanes to drive the filter barrel 3 to rotate. This embodiment does not limit the specific driving method.

[0021] It should be noted that when the filter barrel 3 is driven to rotate by electricity or by the guide vanes on its surface, the top wall of the main body 1 is provided with a bearing or bushing, and a rotating shaft is fixedly connected to the top of the filter barrel 3. This rotating shaft is embedded in the bearing or bushing to achieve rotational support. Furthermore, since the filter barrel 3 needs to rotate continuously while the outlet pipe 4 remains fixed, the two are dynamically sealed together through a rotary sealing connector. Specifically, the rotary sealing connector includes a rotating ring that rotates synchronously with the filter barrel 3 and a stationary ring fixedly connected to the outlet pipe 4. The contact surfaces of the rotating ring and the stationary ring form a sealing pair. The specific structure is a conventional design in this field and will not be described in detail here.

[0022] To avoid setting up an additional electric drive system, in a further embodiment, the kinetic energy of the incoming water flow provides driving force to the filter barrel 3. Specifically, the drive mechanism includes turbine blades 33 and transmission components. Turbine blades 33 are installed inside the water inlet pipe 2; The transmission assembly connects the turbine blades 33 and the filter barrel 3.

[0023] Furthermore, such as Figure 2 As shown, the transmission assembly includes a first rotating shaft 31, a second rotating shaft 35, a first gear, and a second gear 34; One end of the first rotating shaft 31 is fixedly connected to the turbine blade 33, and the other end passes through the top wall of the water inlet pipe 2 and is fixedly connected to the first gear. One end of the second rotating shaft 35 is fixedly connected to the filter barrel 3, and the other end passes through the top wall of the main body 1 and is fixedly connected to the second gear 34. The first gear and the second gear 34 mesh.

[0024] The above structure enables hydraulic self-drive, utilizing the kinetic energy of the incoming water to drive the rotation of the filter barrel 3, requiring no external energy source. Furthermore, the transmission component is coaxially positioned with the filter barrel 3, adapting to the available pipe installation space.

[0025] It should be noted that a first shaft seal assembly is installed between the first rotating shaft 31 and the top wall of the inlet pipe 2; a second shaft seal assembly is installed between the second drive shaft and the top wall of the main body 1. The first and second shaft seal assemblies ensure rotational sealing. In practical applications, the shaft seal assemblies use mechanical seals or stuffing boxes, which are conventional technologies in this field and will not be elaborated here.

[0026] To avoid energy loss and component wear caused by excessive continuous rotation of the filter barrel 3, in a further embodiment, the first gear is an incomplete gear 32. Based on its working principle, the incomplete gear 32 allows for intermittent meshing between the driving and driven gears, thereby preventing excessive continuous rotation. The rotation interval of the filter barrel 3 is determined according to the number of teeth between the incomplete gears 32; for example, the tooth ratio can be 1:3.5 to 4.5.

[0027] To prevent impurities from accumulating on the surface of the filter barrel 3, a further embodiment includes a brush assembly to remove impurities from the outer surface of the filter barrel 36.

[0028] Specifically, such as Figure 3 As shown, the scraper assembly is installed on the inner wall of the main body 1, and the working end of the scraper assembly is elastically pressed against the side surface of the filter bucket 3.

[0029] The working end of the brush assembly is either a scraper 8 or a bristle brush. In this embodiment, the working end of the brush assembly is specifically selected as a scraper 8.

[0030] The scraper assembly actively removes impurities from the filter pores by rotating the filter barrel 3, achieving an anti-clogging design.

[0031] To prevent impurities from accumulating and becoming impossible to remove, a further embodiment also includes an impurity collection unit; The impurity collection unit is detachably installed at the bottom of the main body 1.

[0032] Specifically, in this embodiment, the impurity collection unit includes an impurity collection container 7 and a flange docking mechanism; the flange docking mechanism consists of a first connecting flange 5 and a second connecting flange 6. The first connecting flange 5 is fixed to the bottom opening of the main body 1. The impurity collection container 7 has an opening at one end, and a second connecting flange 6 is provided at the opening end. The first connecting flange 5 is sealed to the second connecting flange 6 through a bolt assembly. A sealing gasket is provided between the flanges, and the impurity collection unit realizes rapid impurity cleaning.

[0033] The working principle of this embodiment is as follows: Water flows through the inlet pipe 2, impacting the turbine blades 33 and driving the first rotating shaft 31 to rotate. The first rotating shaft 31 drives the incomplete gear 32 (the first gear) to periodically mesh with the second gear 34. The second gear 34 drives the filter barrel 3 to rotate intermittently via the second rotating shaft 35. The water from the inlet pipe 2 penetrates the holes of the filter barrel 3 and enters the inner cavity of the filter barrel body 36, where impurities are intercepted on the outer surface. During the rotation of the filter barrel 3, the scraper assembly removes impurities adhering to the outer surface of the filter barrel body 36. Under the influence of gravity, the impurities fall into the bottom impurity collection unit, and the filtered water is output through the outlet pipe 4. During the service life, the impurities in the impurity collection container 7 can be cleaned by periodically disassembling the flange connection.

[0034] This invention uses water flow to impact turbine blades 33, causing the filter barrel 3 to rotate. This avoids the problem of decreased filtration efficiency caused by the accumulation of debris on one side of traditional fixed filter barrels, allowing debris to be evenly distributed on the surface of the filter barrel 3, extending the effective filtration time, and effectively preventing sediment and fine pollutants in the secondary water supply container from entering the user end with the water flow. In addition, the impurity collection unit is easy to clean and maintain, providing the last line of defense for users' water use.

[0035] The intermittent meshing of the incomplete gear 32 and the second gear 34 rotates the gear, thereby driving the filter barrel 3 to rotate intermittently. This ensures that the filter barrel 3 obtains rotational power while avoiding energy loss and component wear caused by excessive continuous rotation.

[0036] In this invention, when water flows through the filter barrel 3, impurities are intercepted on the outer wall of the filter barrel 3, and the filtered water is discharged from the outlet pipe 4. At the same time, the scraper assembly fixed to the inner wall of the main pipe 1 adheres to the outer surface of the filter barrel 3 and continuously scrapes off the attached impurities as the filter barrel 3 rotates. The impurities fall into the impurity collection container 7, reducing the frequency of manual cleaning, lowering maintenance costs, and effectively preventing pipe blockage. The impurity collection container 7 is detachably installed at the bottom of the main pipe 1, making it easy to remove and clean the impurities inside the impurity collection container 7.
