Description

Technical Field

[0001] This utility model relates to the field of pipeline filtration technology, and in particular to a water supply and drainage pipeline filter. Background Technology

[0002] In water supply and drainage systems, pipeline filters are crucial devices for ensuring water quality and preventing impurities from clogging pipes and equipment. Their core function is to intercept suspended solids and particulate impurities in the water. Traditional pipeline filters mostly use filter cartridges or filter screens for mechanical filtration, but over long-term operation, the surface of the filter element will gradually be covered with impurities, leading to decreased filtration efficiency, increased water flow resistance, and even complete clogging.

[0003] Chinese patent CN222900452U discloses a water supply and drainage pipe filter. The filter body is inserted and connected to the inner wall of the connecting shell as a sliding device. The slider is inserted and connected to the inner wall of the sliding shell as a sliding device. The outer wall of the slider is provided with a threaded hole for cooperating with a screw. Turning the screw can make the filter body slide up and down in the connecting shell. The filter cartridge can be replaced and aligned with the connecting pipe. The filter cartridge can be cleaned without throttling.

[0004] However, the cleaning process of this solution requires manually turning the screw to switch the filter cartridge, then disassembling the sealing plate, and manually rotating and removing the filter cartridge for cleaning. This not only increases the labor intensity of operators but also makes it difficult to achieve remote control or automated operation, which is inconsistent with the development trend of modern smart water management and industrial automation. Although it achieves non-stop operation, the structure is usually quite complex, still requiring manual intervention to complete the cleaning operation, resulting in low automation and difficulty in thoroughly cleaning the filter element online, especially with limited effectiveness for highly adhesive impurities. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4A water supply and drainage pipe filter includes a drainage connecting pipe 1 for drainage, a filter pipe 2 fixedly connected to one side of the drainage connecting pipe 1, a movable pipe 3 that moves up and down inside the filter pipe 2, a tapered drainage pipe 4 fixedly connected to the lower surface of the movable pipe 3, an annular filter element 5 inside the movable pipe 3, and a vibration mechanism inside the filter pipe 2, the vibration mechanism including a vibration spring 6, the vibration spring 6 generates fluctuations after being stretched and released, and drives the movable pipe 3 to vibrate at a frequency, thereby vibrating and cleaning the annular filter element 5.

[0023] To filter wastewater, the vibration mechanism also includes a bowl-shaped guide hood 7 fixedly connected to the upper surface of the movable pipe 3. The outer surface of the bowl-shaped guide hood 7 is slidably connected to the inner wall of the filter pipe 2. The upper surface of the annular filter core 5 is fixedly connected to the lower surface of the bowl-shaped guide hood 7. The inner bottom surface of the bowl-shaped guide hood 7 has water inlet holes 8 arranged in a ring array. The lower surface of the annular filter core 5 is fixedly connected to a sealing plate 9. Wastewater enters the filter pipe 2 through the drain connecting pipe 1. Since the outer surface of the bowl-shaped guide hood 7 slides against the inner wall of the filter pipe 2, the wastewater is guided into the bowl-shaped guide hood 7 and enters the annular filter core 5 through the water inlet holes 8. Since the lower surface of the annular filter core 5 is sealed by the sealing plate 9, the wastewater is filtered by the annular filter core 5 and discharged outwards to its surroundings. The filtered wastewater is discharged into the movable pipe 3 and then discharged through the conical drain pipe 4.

[0024] The vibration mechanism also includes a rotating shaft 10 rotatably connected to the upper surface of the filter tube 2 via bearings. A water-blocking pipe 11 extending into the interior of the filter tube 2 is fixedly connected to the lower surface of the filter tube 2. The lower outer surface of the tapered drain pipe 4 is movably inserted into the interior of the water-blocking pipe 11. The rotating shaft 10 extends into the interior of the water-blocking pipe 11. Keyways 12 are symmetrically distributed on the outer surface of the rotating shaft 10. A support ring 13 is fixedly connected to the inner wall of the water-blocking pipe 11 via annularly distributed support rods. A key block 14 is fixedly connected to the inner wall of the support ring 13. The outer surface of the key block 14 slides and engages with the inner wall of the keyway 12. The outer surface of the bowl-shaped guide shroud 7 is connected to the filter... The outer surface of the tube 2 slides in contact. When the bowl-shaped guide shroud 7 moves up and down with the movable tube 3, the sewage flows to the bottom of the filter tube 2 through the movement gap. To prevent it from mixing with the filtered sewage, the small amount of sewage is blocked inside the filter tube 2 by the baffle tube 11. In order to realize the rotation of the movable tube 3 inside the filter tube 2, the key block 14 and the keyway 12 are used to connect the rotating shaft 10 and the support ring 13, thereby ensuring the up and down movement and rotation of the movable tube 3 together with the bowl-shaped guide shroud 7, thereby improving the filtration of sewage and cleaning the impurities on the annular filter element 5 when it vibrates up and down.

[0025] To enable the movable tube 3 and the bowl-shaped guide shroud 7 to move up and down, a magnetic ring 15 is fixedly connected to the inner bottom surface of the bowl-shaped guide shroud 7. Another key block 14, which is slidably engaged with the keyway 12, is fixedly connected to the inner wall of the magnetic ring 15. An electromagnetic generator 16 extending into the filter tube 2 is fixedly connected to the upper surface of the filter tube 2. The electromagnetic generator 16 is movably connected to the outer surface of the rotating shaft 10. When the electromagnetic generator 16 is energized, it generates magnetic force, which in turn attracts the magnetic ring 15 on the bowl-shaped guide shroud 7, thus enabling the movable tube 3 to move linearly on the outer surface of the rotating shaft 10. When the electromagnetic generator 16 is suddenly de-energized, the lifted movable tube 3 falls off and moves downward on the outer surface of the rotating shaft 10. Under the connection of the vibration spring 6, it vibrates after falling off, causing the movable tube 3 and the bowl-shaped guide shroud 7 to vibrate back and forth, thereby removing impurities from the annular filter element 5 during filter cleaning.

[0026] To achieve the cyclic vibration of the movable tube 3, the electromagnetic generator 16 extends to the outer surface of the filter tube 2, the outer surface of the magnet ring 15, the outer surface of the conical drain pipe 4, and the outer surface of the baffle pipe 11, respectively, and rotating rings 17 are rotatably sleeved on them. Vibration springs 6 are fixedly connected to the opposite side surfaces of the two upper rotating rings 17 and the opposite side surfaces of the two lower rotating rings 17. By connecting vibration springs 6 to the upper and lower ends of the movable tube 3, when the magnet ring 15 is attracted, the upper vibration spring 6 is compressed and the lower vibration spring 6 is stretched. After the magnet ring 15 is released, the two vibration springs 6 are reset and move alternately, thereby driving the movable tube 3 together with the bowl-shaped guide shroud 7 to vibrate back and forth, so as to remove impurities from the annular filter element 5.

[0027] By setting up a vibration mechanism consisting of an electromagnetic generator 16, a magnet ring 15, and a vibration spring 6, this utility model can automatically start the cleaning process through PLC control. The electromagnetic circuit drives the moving tube 3 and the filter element to reciprocate at high frequency, which can automatically and efficiently shake off impurities on the surface of the filter element. This completely changes the traditional filter operation mode that relies on manual disassembly and cleaning, greatly reduces labor intensity, and realizes the intelligent and automated cleaning process.

[0028] To clean the filter, a bevel gear set 18 is installed on the upper outer surface of the rotating shaft 10, and a reduction motor 19 is fixedly connected to the upper surface of the filter tube 2. The outer surface of the output shaft of the reduction motor 19 is fixedly connected to the surface of the active bevel gear in the bevel gear set 18. Brush blocks 20 are fixedly connected in a ring array on the outer surface of the movable tube 3. The outer surface of the brush blocks 20 slides in contact with the inner wall of the filter tube 2. When the backwashing system is started, the PLC controls the reduction motor 19 to drive the bevel gear set 18 to rotate, and then transmits the rotation to the rotating shaft 10. When the rotating shaft 10 rotates, the movable tube 3 is rotated through the cooperation of the key block 14 and the keyway 12. Then, multiple brush blocks 20 scrape and clean the inner wall of the filter, and cooperate with the cyclic vibration of the movable tube 3 to clean the annular filter element 5.

[0029] To clean the inner wall of the filter and drain the sewage from the gaps, the lower surface of the filter pipe 2 and the lower surface of the drain connecting pipe 1 are respectively fixedly connected to circulation pipes 21 equipped with solenoid valves. The free end of one circulation pipe 21 is fixedly connected to the lower end of the baffle pipe 11, and the free end of the other circulation pipe 21 is fixedly connected to the inside of the filter pipe 2. Cleaning liquid is introduced into the filter through the drain connecting pipe 1. At this time, the solenoid valves on the two circulation pipes 21 are opened, so that the circulation pipes 21 are connected to the inside of the filter pipe 2 and the inside of the baffle pipe 11 respectively. Then, the cleaning liquid enters the gap between the movable pipe 3 and the filter pipe 2 through the upper circulation pipe 21 for rinsing. The sewage after rinsing enters the baffle pipe 11 through the lower circulation pipe 21 and is discharged together.

[0030] By adopting a structure in which the bowl-shaped flow guide shroud 7 slides and seals with the inner wall of the filter pipe 2, the water flow is effectively guided and short-circuited. The design of the water baffle pipe 11 avoids the mixing of unfiltered water and filtered water. Through the cooperation of the keyway 12 and the key block 14, the complex action of the movable pipe 3, which can move axially and rotate, is cleverly realized. Moreover, the overall structure is integrated inside the pipe, with only the drive component on the outside. The structure is compact, has good sealing performance, and is reliable in operation.

[0031] Working principle: In a specific embodiment of this invention, the wastewater to be treated enters the filter pipe 2 through the drain connecting pipe 1. The wastewater is guided by the bowl-shaped guide hood 7 and flows into the interior through the water inlet holes 8 of the annular array at its bottom. The wastewater enters the sealed filter chamber composed of the bowl-shaped guide hood 7, the annular filter element 5, and the bottom sealing plate 9. Because the sealing plate 9 closes the lower end, the wastewater can only seep out through the filter screen of the annular filter element 5 under pressure. Impurities are trapped inside the filter element. The filtered clean water enters the annular cavity between the movable pipe 3 and the filter pipe 2 and flows downward, finally being discharged through the conical drain pipe 4, completing the filtration cycle.

[0032] When the filter element becomes clogged and needs cleaning, the PLC system automatically starts the cleaning program, which includes two coordinated actions:

[0033] When the electromagnetic generator 16 is powered on, it generates a strong magnetic field that attracts the magnet ring 15 on the bowl-shaped flow guide shroud 7. This causes the entire movable tube 3 assembly to move upward against the elastic force of the vibration spring 6. When the electromagnetic generator 16 is suddenly powered off, the magnetic field disappears instantly. The movable tube 3 assembly falls at high speed under the action of gravity and the restoring elastic force of the upper and lower vibration springs 6. Due to the energy storage and release characteristics of the spring, the movable tube 3 assembly does not simply fall, but generates continuous high-frequency reciprocating vibration. This vibration is directly transmitted to the annular filter core 5, causing the impurities on its inner and outer walls to loosen and fall off due to inertial force.

[0034] While vibrating, the geared motor 19 starts and drives the rotating shaft 10 to rotate through the bevel gear set 18. The rotation of the rotating shaft 10 is driven by the keyway 12 on its surface and the key block 14 fixed to the bowl-shaped guide shroud 7, which in turn drives the entire movable tube 3 assembly to rotate. The brush block 20 fixed to the outer surface of the movable tube 3 rotates accordingly to scrape and clean the inner wall of the filter tube 2 and remove the attached dirt.

[0035] Cleaning fluid is introduced into the drain pipe 1, and the solenoid valves on the two circulation pipes 21 are opened to form a flushing circuit. The cleaning fluid enters from the upper circulation pipe 21 and flushes the annular gap between the moving pipe 3 and the filter pipe 2, washing away the impurities that have been vibrated and brushed down. Finally, the wastewater mixed with impurities enters the baffle pipe 11 from the lower circulation pipe 21 and is discharged with the main water flow to avoid secondary pollution.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
