Description

Technical Field

[0001] This invention relates to the field of wastewater filters, specifically to a high-flow-rate water filter for distributed wastewater treatment and resource recovery / energy utilization. Background Technology

[0002] Wastewater filters are devices used to remove impurities and pollutants from wastewater. They are commonly used in wastewater treatment systems to remove solid particles, suspended solids, organic matter, bacteria, and viruses from wastewater in order to purify the water and meet environmental protection requirements.

[0003] 1. In the traditional wastewater filter process, because wastewater contains a large number of solid particles, these particles easily accumulate on the filter screen during filtration. At the same time, organic and inorganic substances in the wastewater deposit on the filter screen, gradually forming dirt over time, which often leads to clogging of the filter screen. This reduces the water purification efficiency of the wastewater filter and also reduces the flow rate of the purified water. Because the filter screen of a traditional wastewater filter is inside the device, it requires regular manual cleaning or maintenance. The manual cleaning process is relatively cumbersome, and it is inconvenient to manually clean the small wastewater filter. In addition, when the filter screen is clogged, the wastewater filter needs to be shut down for cleaning or replacement, which leads to a long downtime and affects production and processing efficiency. Furthermore, since the filter screen is made of lightweight materials such as non-woven fabric, improper manual operation or untimely maintenance can damage the filter screen during manual cleaning.

[0004] 2. The sludge collection device of the sewage filter is fixed with traditional nuts. However, the traditional nut fixing method is easily affected by vibration and external forces. Moreover, the vibration of the collection equipment over time can cause the nuts to loosen, which will cause the sludge collection device to lose its stability and risk falling off. In addition, when using nuts for fixing, tools are required to tighten and loosen them, especially in confined spaces or when frequent cleaning and maintenance are required, which increases the difficulty of maintenance. Furthermore, the nuts are easily exposed to humid and corrosive environments, and are prone to rust due to oxidation. This can lead to the bolts not being firmly fixed to the sewage filter, and may even affect the service life of the entire sludge collection device.

[0005] Therefore, there is a need to provide a high-flow-rate water filter for the resource recovery and energy conversion of distributed wastewater treatment, aiming to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a high-flow-rate water filter for distributed wastewater treatment and resource recovery and energy utilization.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

A first slide plate is slidably connected to the outer side of the connecting column. A first rotating strip group is rotatably connected inside the first slide plate. A T-shaped block group is rotatably connected to the end of the first rotating strip group away from the first slide plate. Two second slide plates are fixedly connected to the outer side of the connecting column, and a buffer pad is provided on the top of each of the two second slide plates. A second rotating strip group is rotatably connected inside each of the two second slide plates, and the end of the second rotating strip group away from the second slide plate is rotatably connected to the inside of the T-shaped block group. A cleaning block group is fixedly connected to the side of the T-shaped block group away from the first and second rotating strip groups.

[0012] Preferably, the quick-assembly assembly further includes a sludge collection net, which is sleeved on the outside of the annular spacer block. Four T-shaped tubes are slidably connected inside the sludge collection net. Each of the four T-shaped tubes has a cross-shaped groove inside, and a pressing post is slidably connected inside each cross-shaped groove. A platform-shaped post is fixedly connected to one end of each pressing post near the convex groove block. Limiting balls are symmetrically slidably connected inside the cross-shaped grooves. A second return spring is sleeved on the outer wall of each T-shaped tube. One end of the second return spring is fixedly connected to the convex groove block, and the other end is fixedly connected to the T-shaped tube.

[0013] Preferably, the electromagnet is electrically connected to the external driving device.

[0018] The present invention provides a high-flow-rate water filter for distributed wastewater treatment and resource recovery / energy conversion. Compared with the prior art, the advantages of the present invention are:

[0019] 1. By incorporating anti-clogging components, clogging of the wastewater filter screen is prevented, avoiding long-term adhesion of solid particles, biofilm, and dirt to the screen. This ensures the screen's permeability and filtration efficiency, guaranteeing the normal operation of the wastewater treatment system, reducing screen clogging, extending screen lifespan, lowering the frequency of screen replacement, reducing manual intervention and maintenance, lowering operating costs, increasing the clean water flow rate of the wastewater filter, and allowing for cleaning of the wastewater filter without shutting down the system.

[0020] 2. The quick-assembly and disassembly design allows for rapid installation and removal of the wastewater filter sludge collection device. Furthermore, it enables faster disassembly and installation of the sludge collection net, simplifying the maintenance process, reducing maintenance time, and improving equipment availability.

[0021] The purpose of removing the sludge collection device from the filter is to facilitate cleaning and discharge, simplifying the cleaning work, reducing the difficulty of sludge treatment, and preventing the equipment from falling off due to loose nuts and other parts. This improves the safety of the equipment and reduces safety risks. At the same time, the quick-installation device can be applied to different models and specifications of sludge collection devices. Unlike nuts, which require fixing tools for disassembly and assembly, it has a certain degree of versatility and flexibility. Attached Figure Description

[0038] The quick-release assembly includes an annular distance extender 31, which is fixedly connected to the bottom of the circular filter screen 12.

[0039] The anti-clogging component also includes a T-shaped slide post 25, which is slidably connected to the inside of the hollow cylinder 24. A first return spring 26 is sleeved on the outer wall of the T-shaped slide post 25. The top of the first return spring 26 is fixedly connected to the rotating column 22, and the end of the first return spring 26 away from the rotating column 22 is fixedly connected to the bottom of the hollow cylinder 24. A connecting post 27 is fixedly connected to the bottom of the rotating column 22.

A cleaning block group 215 is fixedly connected to the side of the T-shaped block group 214 away from the first rotating strip group 210 and the second rotating strip group 212.

[0040] The quick-assembly assembly also includes a sludge collection net 34, which is sleeved on the outside of the annular spacer block 31. Four T-shaped tubes 35 are slidably connected inside the sludge collection net 34. Each of the four T-shaped tubes 35 has a cross-shaped groove 36 inside. Each cross-shaped groove 36 is slidably connected to a pressing post 37. One end of the pressing post 37 near the convex groove block 33 is fixedly connected to a platform-shaped post 38. Limiting balls 39 are symmetrically slidably connected inside the cross-shaped groove 36. A second return spring 310 is sleeved on the outer wall of each T-shaped tube 35. One end of the second return spring 310 is fixedly connected to the convex groove block 33, and the other end of the second return spring 310 is fixedly connected to the T-shaped tube 35.

[0041] The external drive device is implemented as a motor. The electromagnet 23 is electrically connected to the external drive device. When the external drive device is powered on, the electromagnet 23 is powered on synchronously. The shape of the annular slider 28 is adapted to the shape of the connecting post 27, so that the annular slider 28 can slide on the outside of the connecting post 27. The buffer pad 213 is made of rubber, so that the buffer pad 213 has elasticity and wear resistance. A magnet is provided at one end of the T-shaped slide post 25 near the electromagnet 23, and the magnetic poles of the magnet on the T-shaped slide post 25 are the same as the magnetic poles of the electromagnet 23, so that the electromagnet 23 can push the T-shaped slide post 25 to move when it is powered on.

[0042] The quick-assembly assembly includes an annular spacer block 31, which is fixedly connected to the bottom of the circular filter screen 12. Inside the annular spacer block 31, four convex groove blocks 33 are fixedly connected in an annular shape. A fixed scraper 32 is fixedly connected to the bottom of the annular spacer block 31. A sludge collection net 34 is sleeved on the outside of the annular spacer block 31. Four T-shaped tubes 35 are slidably connected inside the sludge collection net 34. Each of the four T-shaped tubes 35 has a cross-shaped groove 36 inside. A pressing post 37 is slidably connected inside the cross-shaped groove 36. A platform-shaped post 38 is fixedly connected to one end of the pressing post 37 near the convex groove block 33. Limiting balls 39 are symmetrically slidably connected inside the cross-shaped groove 36. A second return spring 310 is sleeved on the outer wall of each T-shaped tube 35. One end of the second return spring 310 is fixedly connected to the convex groove block 33, and the other end of the second return spring 310 is fixedly connected to the T-shaped tube 35.

[0043] The shape of the T-shaped tube 35 is adapted to the shape of the convex groove block 33, so that the T-shaped tube 35 can slide inside the convex groove block 33. A hemispherical groove is symmetrically opened at one end of the T-shaped tube 35 near the convex groove block 33, and the hemispherical groove of the T-shaped tube 35 is adapted to the shape of the limiting ball 39, so that the limiting ball 39 can slide in the hemispherical groove of the T-shaped tube 35. There is an arc-shaped gap between the teeth on the top of the fixed scraper 32, so that the sludge scraped by the cleaning block group 215 can fall into the sludge collection net 34 through the arc-shaped gap of the fixed scraper 32.

[0044] When the staff needs to clean the automatically collected sludge, they first remove the circular filter screen 12 from the top of the wastewater filtration device housing 11. Then, the staff holds the T-shaped tube 35 and presses the pressing column 37 towards the center of the circular filter screen 12. At this time, the pressing column 37 slides along the inside of the cross-shaped groove 36, and the pressing column 37 gradually compresses the second return spring 310. The pressing column 37 also drives the platform column 38 fixedly connected to it to move synchronously. At this time, the platform column 38 disengages from the limiting ball 39, and then the limiting ball 39 slides into the inside of the cross-shaped groove 36 due to gravity. At this time, the limiting ball 39 disengages from the inner wall of the convex groove block 33. Then, the staff pulls out the T-shaped tube 35 away from the annular spacer block 31. The remaining three T-shaped tubes 35 are pulled out one by one in the above steps. At this time, the staff moves the sludge collection net 34 to the bottom of the circular filter screen 12, and then cleans the sludge inside the sludge collection net 34.

[0045] Working principle: In the initial state, neither the first return spring 26 nor the second return spring 310 is compressed, the limiting ball 39 is in contact with the inner wall of the convex groove block 33, and the T-shaped tube 35 is located inside the convex groove block 33.

[0046] When cleaning the wastewater filter screen, the staff first energizes the external drive device. Since there is an electrical connection between the electromagnet 23 and the external drive device, the electromagnet 23 is energized simultaneously with the external drive device.

[0047] Because a magnet is provided at the end of the T-shaped slide column 25 near the electromagnet 23, and the magnetic poles of the magnet on the T-shaped slide column 25 are the same as the magnetic poles of the electromagnet 23, according to the principle that when magnetic poles are the same, their magnetic fields are in opposite directions, causing the magnetic lines of force to cancel each other out, thus generating a repulsive force. At this time, under the action of the repulsive force of the magnetic field, the electromagnet 23 pushes the T-shaped slide column 25 to move away from the electromagnet 23. When the T-shaped slide column 25 slides inside the hollow cylinder 24, it compresses the first return spring 26, and simultaneously pushes the annular slider 28, which is fixedly connected to it, to slide along the outside of the connecting post 27. Block 28 pushes the first sliding plate 29 to slide along the outside of the connecting post 27. At the same time, the first sliding plate 29 drives the first rotating strip group 210 to move synchronously. As a result, the end of the first rotating strip group 210 near the first sliding plate 29 moves towards the end of the second rotating strip group 212 near the second sliding plate 211. At this time, the end of the first rotating strip group 210 away from the first sliding plate 29 rotates inside the T-shaped block group 214, while the end of the second rotating strip group 212 away from the second rotating strip group 212 rotates synchronously inside the T-shaped block group 214. Subsequently, the T-shaped block group 214 drives the cleaning block group 215 to gradually come into contact with the inner wall of the circular filter screen 12.

[0048] Since the external drive device has been powered on, the external drive device drives the rotating column 22 to rotate inside the L-shaped fixed frame 21. Then the rotating column 22 drives the connecting column 27 to rotate synchronously. The connecting column 27 drives the second sliding plate 211 and the second rotating strip group 212 to rotate synchronously. The second rotating strip group 212 drives the T-shaped block group 214 and the cleaning block group 215 to rotate along the inner wall of the circular filter screen 12. Then the cleaning block group 215 scrapes off the sludge on the inner wall of the circular filter screen 12. Through the setting of the anti-clogging component, the filter screen in the sewage filter is prevented from clogging, avoiding the long-term adhesion of solid particles, biofilm and dirt on the filter screen, maintaining the permeability and filtration efficiency of the filter screen, ensuring the normal operation of the sewage treatment system, reducing the occurrence of filter screen clogging, extending the service life of the filter screen, reducing the frequency of filter screen replacement, reducing the frequency of manual intervention and maintenance, reducing operation and maintenance costs, increasing the clean water flow rate of the sewage filter, and achieving the purpose of cleaning the sewage filter without stopping the machine.

[0049] After the cleaning block assembly 215 finishes cleaning the circular filter screen 12, the operator turns off the power to the external drive device, and the electromagnet 23 is also de-energized. At this time, the T-shaped slide column 25 loses its power to move towards the first slide plate 29 due to the de-energization of the electromagnet 23. Subsequently, the first return spring 26 elastically extends, causing the T-shaped slide column 25 to move towards the side closer to the electromagnet 23. At the same time, the T-shaped slide column 25 drives the annular slider 28 to move towards the side closer to the electromagnet 23. The annular slider 28 then drives the first slide plate 29 to slide along the outside of the connecting post 27 away from the second slide plate 211. Subsequently, the first slide plate 29 drives the first rotating bar assembly 210 to move away from the end of the T-shaped block assembly 214. The end of the first rotating bar assembly 210 away from the first slide plate 29 then drives the T-shaped block assembly 214 to move and reset towards the side of the connecting post 27.

[0050] Subsequently, the sludge on the inner wall of the circular filter screen 12 falls to the top of the fixed scraper 32 due to gravity. Then, due to the rotation of the cleaning block assembly 215, and because there is an arc-shaped gap between the teeth at the top of the fixed scraper 32, the cleaning block assembly 215 drives the sludge to fall into the sludge collection net 34 along the arc-shaped gap at the edge of the fixed scraper 32, thus achieving the effect of automatic sludge collection.

[0051] When the staff needs to clean the automatically collected sludge, the staff disassembles the L-shaped fixing bracket 21 and removes the anti-clogging component from the inside of the sewage filter housing 11. Then, the staff first removes the circular filter screen 12 from the top of the sewage filter housing 11. Then, the staff holds the T-shaped tube 35 and presses the pressing column 37 towards the center of the circular filter screen 12. At this time, the pressing column 37 slides along the inside of the cross-shaped slide groove 36. At the same time, the pressing column 37 gradually compresses the second return spring 310, and the pressing column 37 drives the platform column 38 fixedly connected to it to move synchronously. At this time, the platform column 38 disengages from the limiting ball 39. Then, the limiting ball 39 slides into the inside of the cross-shaped slide groove 36 due to gravity. At this time, the limiting ball 39 disengages from the inner wall of the convex groove block 33. Since the shape of the T-shaped tube 35 is adapted to the shape of the convex groove block 33, the staff then pulls the T-shaped tube 35 out of the inside of the convex groove block 33 away from the annular spacer block 31.

[0052] Subsequently, the staff followed the previous steps to pull out the remaining three T-shaped tubes 35 one by one. At this time, the staff moved the sludge collection net 34 to the bottom of the circular filter screen 12, and then collected the sludge inside the sludge collection net 34. The quick-disassembly and assembly design achieves the purpose of quickly installing and disassembling the sewage filter sludge collection device. Secondly, it allows for faster disassembly and installation of the sludge collection net 34, simplifying the maintenance process, reducing maintenance time, and improving equipment availability. It also facilitates the removal and assembly of the sludge collection device from the filter for cleaning and discharge, simplifying cleaning work, reducing the difficulty of sludge treatment, and preventing equipment from falling off due to loose nuts or other parts, thus improving equipment safety and reducing safety risks. At the same time, the quick-disassembly and assembly device is applicable to different models and specifications of sludge collection devices, unlike nuts which require fixing tools for disassembly and assembly, thus possessing a certain degree of versatility and flexibility.

[0053] After the workers have finished collecting the sludge inside the sludge collection net 34, they attach the top of the sludge collection net 34 to the outside of the annular spacer block 31. Reversing the previous process, the workers hold the T-shaped tube 35 and press the pressing post 37 towards the center of the circular filter screen 12. At this time, the limiting ball 39 slides into the interior of the cross-shaped groove 36. Then, the T-shaped tube 35 is moved along the top of the sludge collection net 34 into the interior of the convex groove block 33. Finally, the workers stop pressing the pressing post 37. The second return spring 310 elastically extends, causing the pressing column 37 to slide in the opposite direction along the inside of the T-shaped tube 35. At the same time, the pressing column 37 drives the pediment column 38 to move towards the side closer to the sludge collection net 34. At this time, the pediment column 38 again abuts against the limiting ball 39, and the pediment column 38 drives the limiting ball 39 to move into the hemispherical groove of the T-shaped tube 35. Then, the limiting ball 39 abuts against the inner wall of the convex groove block 33 again, achieving the effect of restricting the T-shaped tube 35 inside the convex groove block 33.
