Description

Technical Field

[0001] This invention relates to the field of water conservancy and chemical pipeline transmission engineering technology, and in particular to a self-cleaning filter device for liquid bends. Background Technology

[0002] Currently, water supply, sewage, and liquid transmission pipeline systems often contain large amounts of silt, sand, and irregular impurities, affecting liquid flow. For water supply and sewage pipelines, the long-term presence of silt and irregular impurities can lead to sedimentation on the pipe walls, hindering water flow and potentially causing blockages, thus impacting water supply and drainage quality. For liquids transported in production processes, maintaining cleanliness is crucial, especially for hazardous liquids such as chemicals. Blockages not only disrupt production but can also pose serious risks if not handled properly. Therefore, measures are needed to treat and filter these harmful impurities and particles, creating a clean filtration system to prevent blockages and avoid disruptions to daily life and production. While most systems employ pre-filters or passively manage blockages, they struggle to effectively remove intrusive particles, especially when their quantity is high. Therefore, an automated pipeline filtration system is necessary. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the long-standing issues of silt and irregular impurities in current water supply and sewage pipelines, which cause pipe blockages and affect the quality of production water, this invention provides a liquid bend self-cleaning filter and its control system. This system has the advantages of strong cleaning ability, high level of automation, and convenient installation and maintenance.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-13 As shown, the present invention provides a liquid bend self-cleaning filter device, including a main pipe 1 whose inner side wall is machined with a crescent-shaped groove and pin holes by a CNC milling machine, and is fitted and connected to an embedded connecting plate 2. The outer circumference of the embedded connecting plate 2 is machined by wire cutting to fit the diameter of the main pipe 1. The lower end of the embedded connecting plate 2 is drilled to form pin holes, and is connected to a filter connecting plate 3 by pins. The lower end of the filter connecting plate 3 is machined with pin holes, and is connected to a guide rod 5 and a shrink filter plate 4 by pins respectively.

[0037] Using integrated processing technology, the guide rod 5 and the shrink filter plate 4 are processed as a whole. The guide rod 5 is located in the middle of the shrink filter plate 4. The lower end of the guide rod 5 is processed with bolt hole structure through precision milling and drilling technology. It is connected to the rotary switch 7 by bolts. The rubber sealing ring 6 for sealing liquid is fixed inside the rotary switch 7 by adhesive bonding technology.

[0038] The bottom of the shrink filter plate 4 is in contact with the wall of the main pipe 1 with a cylindrical surface. A cylindrical groove is processed on the wall surface by drilling technology to form a rotating shaft. The filter connecting plate 3, the shrink filter plate 4, and the guide rod 7 are made of lightweight porous metal material and have a filtering function. As the skeleton of the filtering mechanism, they can filter large particulate impurities.

[0039] The rotary drive mechanism is supported by the fixed base 10. Driven by the hydraulic cylinder 9, the rotary switch 7 (the rotary switch 7 is manufactured by cutting a circular structure from the main pipe 1 using thermal cutting technology, and the edges and corners are rounded to adapt to the rotation of the rotary structure) rotates counterclockwise with the rotary support arm 8, driving the guide rod 5 to move. The filter connecting plate 3 and the shrink filter plate 4 move toward the rotary switch 7 under the action of the guide rod 5, and are pulled into the connecting plate 2. At the same time, the filter connecting plate 3 comes into contact with the rotary switch 7 after being pulled. The resulting vibration can transport the filtered impurities and particles into the conveying bend 11, and the filtered material is discharged under the action of the rotating conveying screw shaft 12.

[0040] The control structure is a dual closed-loop control design. A pressure sensor is installed at the rotary switch 7. When the detected pressure exceeds a certain threshold, the pressure sensor sends a control signal to the controller, which activates the hydraulic cylinder 9, opens the rotary switch 7, and allows impurities to enter the inlet of the conveying bend 11 through vibration and liquid flushing. At the same time, the conveying screw shaft 12 is opened to discharge the filtered impurities through the conveying bend 11.

[0041] The invention is implemented as follows: A filter plate device and a control system are installed inside the main pipe 1 to form an automatic filtration system for curved pipes. An embedded connecting plate 2 is connected to the inner wall of the main pipe 1 via pins. The outer circumference of the embedded connecting plate 2 fits the diameter of the main pipe. The lower end of the embedded connecting plate 2 is connected to a filter connecting plate 3 via pins. The lower end of the filter connecting plate 3 is connected to a guide rod 5 and a shrinking filter plate 4 via pins. The guide rod 5 divides the shrinking filter plate 4 into two parts at the middle position. The lower end of the guide rod 5 is connected to a rotary switch 7 via bolts. A rubber sealing ring 6 for sealing the liquid is provided inside the rotary switch 7. The bottom of the shrink filter plate 4 is in cylindrical contact with the wall of the main pipe, forming a rotating shaft. Supported by the fixed base 10 and driven by the hydraulic cylinder 9, the rotary switch 7 rotates counterclockwise with the rotating support arm 8, driving the guide rod 5 to move. The filter connecting plate 3 and the shrink filter plate 4 move towards the rotary switch 7 under the action of the guide rod 5, pulling the embedded connecting plate 2 to move. At the same time, the filter connecting plate 3 comes into contact with the rotary switch 7 after the pulling movement. The resulting vibration can transport the filtered impurities and particles into the conveying bend 11. Under the action of the rotating conveying screw shaft 12, the filtered material is discharged. During the filtration process, a pressure sensor is installed at the rotary switch 7. When the detected pressure exceeds a certain threshold, the pressure sensor sends a control signal to the controller, starting the hydraulic cylinder 9 to open the rotary switch 7 and simultaneously open the conveying screw shaft 12, discharging the filtered impurities through the conveying bend 11.

[0042] The technical effects of this invention are:

[0043] Based on structural design theory, mechanism motion theory, fluid mechanics theory, and automatic control theory, this invention can effectively and automatically filter impurity particles in pipelines.

[0044] By utilizing signal transmission automatic control methods, the motion principle between mechanical parts, and the filtration performance of porous filter materials, an automatic control mechanical motion filtration mechanism is formed. This mechanism can filter impurities and particles in liquids. The main body of the porous filter material consists of filter connecting plate 3 and shrink filter plate 4. The substrate is made of through-hole hard alloy, which serves as a skeleton support and filters large particles. The surface is covered with multiple layers of multi-specification soft filter materials, which can be replaced according to different filtration levels to achieve adjustment under multiple operating conditions.

[0045] The guide rod 5 is located in the middle surface of the shrink filter plate 4, and its lower end is connected to the rotary switch 7 by bolts. The inner side of the rotary switch 7 is provided with a rubber sealing ring 6 to seal the liquid. The rotary switch 7 is combined with the sealing pipe to seal the liquid. The bottom of the shrink filter plate 4 is in contact with the wall of the main pipe and rotates around the cylindrical surface. The hydraulic cylinder 9 drives the rotary switch 7 to rotate counterclockwise with the rotating support arm 8, forming the traction mechanism of the filtration system.

[0046] The guide rod 5 moves under the traction of the rotary switch 7, which drives the filter connecting plate 3 and the shrink filter plate 4 to move with the rotary switch 7, and pulls the embedded connecting plate 2 to move. At the same time, the filter connecting plate 3 comes into contact with the rotary switch 7 after being pulled, and the resulting vibration and inertia can transport the filtered impurities and particles into the conveying bend 11. Under the action of the rotation of the conveying screw shaft 12, the filtered material is discharged.

[0047] During the filtration process, an automatic adjustment system is set up. A pressure sensor is installed at the rotary switch 7. When the detected pressure exceeds a certain threshold, the pressure sensor sends a control signal to the controller, which activates the hydraulic cylinder 9, opens the rotary switch 7, and simultaneously opens the conveying screw shaft 12 to discharge the filtered impurities through the conveying bend 11, thus forming an automatic closed-loop control system.

[0048] The system proposed in this invention has the advantages of strong cleaning ability, high level of automation, and convenient installation and maintenance. At the same time, because this invention can freely adjust the porosity of the filter structure to achieve multiple working conditions, it further improves the filtration capacity and efficiency of the new liquid bend self-cleaning filter and its control system.

[0049] This invention has the following characteristics:

[0050] The embedded connecting plate 2, filter connecting plate 3, shrink filter plate 4, and guide rod 5 on the inner wall of the main pipe 1 are connected by pins to form a multi-joint mechanism with relatively free movement. The lower end of the guide rod 5 is connected to the rotary switch 7 by bolts. The inner side of the rotary switch 7 is equipped with a rubber sealing ring 6 for sealing liquid. The bottom of the shrink filter plate 4 is in contact with the cylindrical surface of the main pipe wall to form a rotating shaft. Driven by the supporting hydraulic cylinder 9, the rotary switch 7 is opened or closed, driving the multi-joint mechanism to move. The rotary switch 7 rotates counterclockwise with the rotating support arm 8, driving the guide rod 5 to move. The filter connecting plate 3 and shrink filter plate 4 move towards the rotary switch 7 under the action of the guide rod 5. At the same time, the filter connecting plate 3 contacts the rotary switch 7 after the motion. The resulting vibration can transport the filtered impurities and particles into the conveying bend 11. Under the action of the rotating conveying screw shaft 12, the filtered material is discharged. The outer circumference of the embedded connecting plate 2 fits the diameter of the main pipe. When moving, it forms liquid pressure and shear force along the filter plate, which can push the impurity particles towards the outlet of the rotary switch 7, improving cleaning efficiency.
