Description

Technical Field

[0001] This invention belongs to the field of building water supply and drainage technology, and particularly relates to a building water supply and drainage device for preventing blockage. Background Technology

[0002] In recent years, with the rapid development of the domestic economy and the improvement of residents' living standards, the annual discharge of domestic sewage has been increasing. Drainage networks, especially existing ones in renovation projects, often bear a heavy burden. Meanwhile, people's demands for a higher standard of living are rising, and sewage network blockages prevent sewage discharge, leading to outdoor sewage overflows, foul odors, and even backflow into indoor spaces, seriously affecting users' normal lives and work. Furthermore, in communities with sewage treatment facilities, the pipe network before the sewage enters the treatment plant usually needs to be intercepted to ensure the normal operation of the machinery. Therefore, to ensure drainage safety, improve drainage efficiency, and reduce subsequent maintenance costs, inventing an anti-clogging building water supply and drainage device is particularly important.

[0003] In the field of building water supply and drainage, there is currently no effective method to prevent blockage of domestic sewage pipes. This is because the usual approach involves designing pipes with appropriate slopes, pipe diameters, and ventilation facilities to ensure smooth water flow. Septic tanks are used to remove some solid waste. However, Article 3.3.6 of the "Outdoor Drainage Design Standard" GB50014-2021, implemented on January 1, 2021, states that septic tanks should not be installed in separate drainage systems in urban areas where sewage collection and centralized treatment facilities are already in place. This is because installing septic tanks would reduce the quality of influent to sewage treatment plants, hindering their treatment efficiency. Therefore, omitting septic tanks essentially eliminates a process for solid waste to settle in the pipe network, increasing the risk of blockage, especially in densely populated areas or residential communities where pipe loads are high, pipes are long, and have many bends, making blockages more likely.

[0004] In commonly used sewage pipe networks, some have a set of filter screens before the sewage enters the treatment facilities set up in the community. The filtration effect is not good, and the mesh of the filter screen cannot be cleaned well. Dirt easily gets stuck in the mesh, causing blockage. When larger impurities enter the drainage device, such as large plastic bags, they are easy to stay on the filter screen and are not easy to be discharged, causing blockage of the filter screen and leading to blockage of the drainage device.

[0005] Chinese patent CN114607030A discloses an anti-clogging building water supply and drainage device, including a water tank, a first filter plate, a drain pipe, a second filter plate, and a water inlet pipe. The drain pipe is connected to the water tank, the second filter plate is installed at one end of the drain pipe, and the first filter plate is hinged inside the water tank. The anti-clogging building water supply and drainage device further includes a water distribution component, which is disposed on the water tank and connected to the water inlet pipe, for evenly distributing water from the water inlet pipe onto the first filter plate. This invention, by incorporating a striking component and an elastic element, automatically and efficiently moves debris from the surface of the first filter plate to one side of its surface after the first filter plate filters the water discharged into the water tank, thus preventing debris from adhering to the surface of the first filter plate and affecting its filtration efficiency.

[0006] Although the aforementioned patent filters water, it does not have a cleaning function for the first filter plate, which makes it easy for debris to accumulate. The debris also needs to be treated or disposed of separately outside this device, which is not conducive to the removal of debris in the drainage. Summary of the Invention

[0013] Preferably, a horizontal plate is fixedly connected to one end of the cleaning roller, a second motor is mounted on the horizontal plate, and a turntable is fixedly connected to the output end of the second motor via a connecting shaft. A long shaft is fixedly connected to the other side of the turntable, and a turntable is also fixedly connected to the other end of the long shaft. Both turntables have arc-shaped grooves extending through their sidewalls, and sliding rods are movably mounted within these grooves. A scraper is fixedly connected to both sliding rods.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The anti-clogging component of the present invention drives the cleaning rollers above the two filter plates to roll by a motor. The first filter plate filters out larger impurities in the sewage, and the filtered sewage then passes through the second filter plate to filter out smaller impurities. The bristles brush the filter holes on the two filter plates, cleaning out the impurities that clog the filter holes, thereby preventing the accumulation of impurities in the sewage from clogging the drainage device. The rotation of the bidirectional screw drives the sliding rods on both sides of the cleaning roller to slide in the wave-shaped groove, forming an up-and-down bouncing effect. Combined with the bristles, this makes the cleaning effect on the filter holes on the filter plate better. The anti-clogging component also drives the turntable to rotate by the rotation of the motor, so that the sliding rod carries the scraper down to the upper surface of the first filter plate. With the rotation of the bidirectional screw, the sliding rods on both sides of the cleaning roller slide in the wave-shaped groove, so that the scraper moves along the surface of the first filter plate, scrapes the impurities on the surface of the first filter plate, and scrapes them into the processing box, removing the large impurities on the first filter plate and further improving the cleaning effect on the upper filter plate.

[0022] (2) The crushing device of the present invention drives the meshing transmission of helical gears by rotating the bidirectional screw and drives the meshing transmission of transmission gears by using a transmission belt, thereby realizing the rotation of blades on two sets of rotating shafts, crushing impurities in the processing box, increasing storage space, avoiding blockage by larger impurities, and allowing the box door to be opened to clean the upper and lower layers inside the device. The overall filtration effect is good and the anti-clogging effect is better. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Furthermore, the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0033] Example

[0034] A clog-resistant building water supply and drainage device includes a water tank 1, an inlet pipe 2 connected to the upper end of the water tank 1, an outlet pipe 3 connected to the lower end of the water tank 1, a treatment tank 4 provided on one side of the water tank, an opening 8 and an opening 22 extending through the water tank 1 near the treatment tank 4, a crushing component provided inside the treatment tank 4, a door 5 provided on the side of the treatment tank 4 away from the water tank 1, a connecting pipe 6 provided at the bottom of the treatment tank 4, and the outlet of the connecting pipe 6 connected to the outlet pipe 3;

[0035] The top of the water tank 1 has two symmetrical horizontal slots. A bidirectional lead screw 12 is rotatably installed in each of the two horizontal slots of the water tank 1. A collar 13 is screwed onto the bidirectional lead screw 12. One end of the bidirectional lead screw 12 is controlled to rotate by a motor 3. The other end of the bidirectional lead screw 12 is fixedly connected to a horizontal shaft 35. A helical gear 38 is fixedly connected to the end of the horizontal shaft 35 away from the bidirectional lead screw 12. The water tank 1 also has a filter plate 9 and a filter plate 10. Both the filter plate 9 and the filter plate 10 have several sets of filter holes. The filter plate 9 is located above the filter plate 10. Anti-clogging components are provided above both the filter plate 9 and the filter plate 10.

[0036] In use, wastewater enters the water tank 1 through the inlet pipe 2, and larger impurities in the wastewater are filtered out through the filter holes on the filter plate 9. The filtered wastewater then passes through the filter holes on the filter plate 10 to filter out smaller impurities, and finally flows out through the outlet 3.

[0037] In this embodiment, the anti-clogging component includes a limiting frame 18, which is fixed on opposite sides inside the water tank 1. The limiting frame 18 is respectively located above the first filter plate 9 and the second filter plate 10, and the limiting frame 18 has a wavy groove 19. A first cleaning roller 11 is provided above the first filter plate 9, and a second cleaning roller 23 is provided above the second filter plate 10. Several sets of bristles 21 are fixed on the outer walls of the first cleaning roller 11 and the second cleaning roller 23. Short shafts 29 are fixedly connected to both ends of the first cleaning roller 11 and the second cleaning roller 23. Hollow discs 16 are provided on both sides of the first cleaning roller 11 and the second cleaning roller 23. A first motor is fixed inside the hollow disc 16. The output end of the first motor is fixedly connected to the short shaft 29. A sliding rod 20 is fixedly connected to the side of the hollow disc 16 away from the short shaft 29. The sliding rod 20 is slidably connected in the wavy groove 19.

[0038] It should be noted that the two ends of the limiting frame 18 are connected and fixed to the side wall inside the water tank 1 by connecting plates. The limiting frame 18 is set on the filter plate 1 9 and the filter plate 2 10. The cleaning roller 1 11 and the cleaning roller 2 23 are installed in the corrugated groove 19 by sliding rod 20, so that the distance from the cleaning roller 1 11 to the filter plate 1 9 and the distance from the cleaning roller 2 23 to the filter plate 2 10 reach the predetermined distance, so that the bristles can clean the upper surface of the filter plate. The motor 1 can drive the short shaft 29 to rotate, so that the cleaning roller 1 11 and the cleaning roller 2 23 rotate, and the bristles brush the impurities on the filter plate 1 9 and the filter plate 2 10, so as to remove the impurities in the filter holes and avoid the clogging of the filter holes.

[0039] In this embodiment, an L-shaped connecting plate 15 is fixedly connected to the upper end of the outer wall of the hollow disk 16 located on both sides of the cleaning roller 11 and the cleaning roller 23. A connecting rod 17 is fixedly connected to the upper end of the L-shaped connecting plate 15. An L-shaped connecting plate 24 is also sleeved on the connecting rod 17. The connecting rod 17 and the L-shaped connecting plate 24 are movably connected. A spring is sleeved on the connecting rod 17 located between the L-shaped connecting plate 15 and the L-shaped connecting plate 24. The L-shaped connecting plate 24 located above the cleaning roller 11 is fixedly connected to the outer wall of the collar 13. The L-shaped connecting plate 24 located above the cleaning roller 23 is fixedly connected to the outer wall of the hollow disk 16 on the side of the cleaning roller 11.

[0040] Motor 3 drives the bidirectional lead screw 12 to rotate, forming a lead screw drive with the collar 13. The bidirectional lead screw 12 drives the collar 13, which in turn drives the slide rods 20 of the two cleaning rollers to bounce up and down and slide in the corrugated groove 19. In conjunction with the rotation of the cleaning rollers, the cleaning roller 1 11, the cleaning roller 23, and the bristles 21 vibrate up and down, resulting in a better cleaning effect on the filter holes on the filter plate 1 9 and the filter plate 2 10, thereby achieving the anti-clogging function. Among them, when the slide rod 20 bounces up and down within the limiting frame 18 through the corrugated groove 19, It drives the hollow disc 16 to move up and down, and the L-shaped connecting plate 15 connected to the outer wall of the hollow disc 16 moves up and down. Because the connecting rod 17 and the L-shaped connecting plate 14 are movably connected, the L-shaped connecting plate 15 drives the connecting rod 17 to move up and down along the inside of the L-shaped connecting plate 14, which limits the up and down movement of the hollow disc 16 and prevents it from deviating. The L-shaped connecting plate 14, the connecting rod 17 and the L-shaped connecting plate 15 also serve to connect the collar 13 and the hollow disc 16. The spring is used for support and limitation.

[0041] Furthermore, grooves can be opened through both sides of the filter plate 9, and the L-shaped connecting plate 14 above the cleaning roller 23 passes through the grooves and connects with the hollow disc 16 of the cleaning roller 11.

[0042] In this embodiment, a horizontal plate 26 is fixedly connected to one end of the cleaning roller 11. A motor 2 is installed on the horizontal plate 26. The output end of the motor 2 is fixedly connected to a turntable 25 via a connecting shaft. A long shaft 27 is fixedly connected to the other side of the turntable 25. The other end of the long shaft 27 is also fixedly connected to the turntable 25. An arc-shaped groove 30 is provided through the sidewalls of both turntables 25. A sliding rod 31 is movably provided in the arc-shaped groove 30. A scraper 28 is fixedly connected to both sliding rods 31. A horizontal groove is provided through the outer sidewall of the cleaning roller 11. The scraper 28 is located in the horizontal groove.

[0043] The horizontal plate 26 is used to fix the second motor. The second motor drives the connecting shaft on the side of the horizontal plate 26 to rotate. The connecting shaft is fixedly connected to the turntable, thereby driving the turntable 25 to rotate. The long shaft 27 is used to connect the two turntables 25. When the turntable 25 on the side of the horizontal plate 26 rotates, the turntable 25 at the other end also rotates. The rotation of the turntable 25 causes the sliding rod 31 to move down into the horizontal groove with the scraper 28 under the rotation of the arc groove 30 and to be located on the upper surface of the filter plate 9. When in use, the first motor in the hollow plate needs to be turned off so that the cleaning roller 11 does not rotate and the horizontal groove of the cleaning roller 11 is located directly above the filter plate 9. The third motor is started to drive the bidirectional lead screw 12 to rotate. The sliding rod 20 moves along the wave-shaped groove 19 opened on the limiting frame 18, so that the cleaning roller 11 drives the scraper to scrape the impurities on the filter plate 9 through the opening 8 and send them into the processing box 4, thereby realizing the function of removing impurities on the filter plate 9.

[0044] In this embodiment, the processing box 4 is provided with a filter plate 31 and a partition plate 32. The filter plate 31 and the filter plate 9 are on the same horizontal plane. The filter plate 31 has several sets of filter holes through it. The partition plate 32 is located between the filter plate 31 and the top plate of the processing box 4.

[0045] In this embodiment, the crushing component includes two rotating shafts 33, the upper ends of which extend through a partition 32. A transmission gear 34 is fixedly connected to the top of each of the two rotating shafts 33, and the two transmission gears 34 mesh with each other. Multiple blades 42 are fixedly mounted on each rotating shaft 33 located below the partition 32. A vertical shaft 36 is also rotatably connected to the partition 32. A helical gear 37 is mounted on the upper end of the vertical shaft 36, and the helical gear 37 meshes with a helical gear 38. A transmission belt 39 is fitted between the helical gear 37 and one of the rotating shafts 33 for transmission connection.

[0046] The partition 32 is used to isolate the first helical gear 37, the second helical gear 38 and the transmission gear 34, so that their transmission is not affected by impurities. It should be noted that vertical partitions should be set around the partition 32 to form a closed cavity at the top of the processing box 4 to protect the gear transmission and prevent impurities from entering and damaging the gear transmission, thus causing device failure.

[0047] The double-acting lead screw 12 drives the second helical gear 38 to mesh with the first helical gear 37, and the transmission belt 39 drives the rotating shaft 33 to rotate. Furthermore, the lower end of the rotating shaft 33 can be rotatably connected to the third filter plate 41, or it can extend beyond the lower end of the third filter plate 41, ensuring its rotation remains vertical and prevents deviation. The rotation of the rotating shaft 33 causes the transmission gears 34 at its top to mesh with each other. Ultimately, the blades 42 on the two sets of rotating shafts 33 crush the impurities. One set of rotating shafts 33 rotates clockwise, and the other rotates counterclockwise, resulting in a better crushing effect of the blades 42 on the impurities.

[0048] In this embodiment, opening 8 and opening 22 are connected to the interior of the processing tank 4. The bottom plate of the processing tank 4 is provided with a water outlet, which is connected to the connecting pipe 6. A filter screen is provided on the water outlet.

[0049] The filter screen is designed to prevent impurities from falling into the connecting pipe 6 and causing blockage when cleaning impurities on the filter plate 210.

[0050] In this embodiment, one side of the door 5 is hinged to the processing box 4, and a door lock 40 is provided between the other side of the door 5 and the processing box.

[0051] When it is necessary to clean impurities, you can open the door lock 40 to clean them. After cleaning, close the box door and close the door lock 40.

[0052] In this embodiment, a flow guide groove 7 is provided below the filter plate 2 10, and the bottom of the flow guide groove 7 is connected to the water outlet pipe 3.

[0053] In this embodiment, the bottom surface of the first opening 8 is at the same height as the upper surface of the first filter plate 9, and the bottom surface of the second opening 22 is at the same height as the upper surface of the second filter plate 10.

[0054] The working principle of the anti-clogging building water supply and drainage device of the present invention is as follows:

[0055] In use, drive the bidirectional lead screw 12 to rotate, turn on motor one, and the bidirectional lead screw 12 drives the slide bar 20 to slide in the wavy groove 19. The cleaning roller one 11 and the cleaning roller two 23 start to rotate. As the slide bar 20 moves up and down along the wavy groove 19, the rotation of the cleaning roller drives the bristles 21 to brush the surface of the filter plate, so that the impurities on the filter holes are cleaned out to avoid clogging. When it is necessary to crush the impurities, turn off motor one, the cleaning roller stops rolling, turn on motor two, the turntable 25 drives the scraper 28 to move down into the horizontal groove, and the scraper 28 moves down to the upper surface of the cleaning roller one 11. As the slide bar 20 moves up and down along the wavy groove 19, the scraper 28 scrapes the impurities on the filter plate one 9 and sends them to the processing box 4. The bidirectional lead screw 12 drives the rotating shaft 33 to rotate, causing the blade 42 to crush the impurities. The crushed impurities can be cleaned by opening the box door 5 when all the motors of the device are turned off.

[0056] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
