Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more particularly to a sewage treatment device based on high-efficiency activated carbon. Background Art

[0002] With the acceleration of industrialization and urbanization, the complex components in sewage, such as organic pollutants, heavy metal ions, color and odor, are increasing. Traditional sewage treatment processes can no longer meet the increasingly stringent emission and reuse standards. Activated carbon has a unique porous structure and a huge specific surface area. It can effectively remove non-biodegradable organic matter, heavy metals (such as lead and mercury), residual chlorine and various toxic and harmful substances in sewage through the dual effects of physical adsorption and chemical adsorption, significantly improving water quality. In addition, activated carbon has a strong ability to remove color and odor in sewage. It is a key technical means to achieve deep purification of sewage and ensure that the effluent water quality is stable and meets the standards. It plays an irreplaceable role in the fields of deep treatment of industrial wastewater, purification of drinking water, and reuse of reclaimed water.

[0003] In traditional sewage treatment processes, impurities such as mud, fiber, and colloids carried in sewage can easily accumulate on the surface of the activated carbon layer. These impurities will block the pore structure of the activated carbon, resulting in the activated carbon in the covered area unable to fully contact the sewage, significantly reducing the adsorption efficiency. At the same time, the accumulation of impurities will also change the water permeability of the activated carbon layer, causing the water flow to form high-speed channels locally. Over time, the continuous scouring of the water flow will cause the activated carbon layer to have uneven phenomena such as depressions and gullies, causing sewage to short-circuit and unable to effectively contact the activated carbon, which not only reduces the sewage treatment effect, but also accelerates the loss of activated carbon.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Refer to the instruction manual Figures 1-9As shown, a sewage treatment device based on high-efficiency activated carbon in an embodiment of the present invention includes a treatment tower 1, and a guide cover 2 is connected to the middle of the upper end of the inner wall of the treatment tower 1, and the guide cover 2 is a V-shaped structure. The sewage enters the interior of the guide cover 2 through the water inlet pipe 3, and the water is drained to the middle of the centrifugal disk 5 through the guide cover 2. The upper part of one side of the guide cover 2 is connected to the water inlet pipe 3, and the shape of the water inlet pipe 3 is an L-shaped structure. The upper end of the water inlet pipe 3 extends through and extends to the upper end of the treatment tower 1. The middle of the upper end of the treatment tower 1 is connected to a decontamination mechanism, and leveling mechanisms are connected above the second filter plates 23 on both sides of the inner wall of the treatment tower 1.

[0018] The impurity removal mechanism can be used to throw large particles of impurities and sediment remaining in the sewage to the wall of the treatment tower 1 to prevent impurities from entering the activated carbon layer along with the sewage. At the same time, the impurity removal mechanism can facilitate the cleaning of impurities adhering to the tower wall. At the same time, the leveling mechanism can level the activated carbon ions inside the connecting cylinder 21 to avoid uneven activated carbon ions inside the connecting cylinder 21. When sewage flows down from different positions, the adsorption effect is different, which affects the sewage treatment effect. During actual use, sewage enters the interior of the deflector 2 through the water inlet pipe 3. The deflector 2 guides the water to the centrifugal disk 5 inside the impurity removal mechanism. Through centrifugal action, large particles of impurities in the sewage are thrown to the tower wall, which can remove most of the impurities and prevent impurities from accumulating above the activated carbon layer, causing blockage and affecting the sewage treatment effect. Subsequently, the activated carbon particles inside the activated carbon layer can be leveled by the leveling mechanism to ensure the sewage treatment effect.

[0019] like Figure 2 、 7 As shown, the impurity removal mechanism includes a drive motor 4 and a gear ring 10. The output end of the drive motor 4 extends through the inside of the processing tower 1. The output end of the drive motor 4 is connected to a centrifugal disc 5. The centrifugal disc 5 is located directly below the air guide 2. The inner wall of the processing tower 1 corresponds to the lower part of the outer wall of the centrifugal disc 5 and is connected to a gathering ring 6. One side of the lower end of the gear ring 10 is connected to a first scraper 11. The upper part of one side of the first scraper 11 is connected to a second scraper 12. The lower end of the first scraper 11 is connected to a scraping block 13. The middle of the outer wall of the air guide 2 is connected to a baffle 7. One side of the upper end of the processing tower 1 is connected to a cleaning motor 8. The cleaning motor 8 output The output end extends through to the interior of the processing tower 1, and the output end of the cleaning motor 8 is connected to a gear 9, one side of the gear 9 is meshed with one side of the inner wall of the gear ring 10, and the upper end of the gear ring 10 is connected to a guide ring, and a stabilizing ring is connected to the guide ring at the upper end of the inner wall of the processing tower 1. A slide groove is provided at the corresponding guide ring below the stabilizing ring, and the upper end of the guide ring slides inside the slide groove. The second scraper 12 is in an inverted L-shaped structure. The upper end of the second scraper 12 contacts one side of the lower end of the baffle 7, and one side of the second scraper 12 contacts one side of the outer wall of the air guide cover 2. The lower end of the scraper block 13 slides on the inner wall of the aggregate ring 6.

[0020] The shape of the aggregate ring 6 is set in an arc shape. The aggregate ring 6 is made of a mesh material to facilitate the falling of sewage. When the sewage falls to the center of the centrifugal disc 5, the driving motor 4 drives the centrifugal disc 5 to rotate at high speed. The centrifugal force generated causes the suspended matter in the sewage, such as mud, fiber, etc., to be thrown toward the inner wall of the treatment tower 1 due to the density difference, and slides along the wall to the aggregate ring 6 for collection. The liquid sewage is thrown out from the edge of the centrifugal disc 5 and falls under the combined action of centrifugal force and gravity. At the same time, the cleaning motor 8 drives the gear 9 to engage the gear ring 10 to rotate, so that the first scraper 11, the second scraper 12 and the scraper block 13 rotate synchronously. The second scraper 12 scrapes off impurities attached to the outer wall of the deflector 2 and under the baffle 7. The first scraper 11 scrapes the inner wall of the treatment tower 1, and scrapes the tower wall impurities into the inside of the aggregate ring 6. The scraper block 13 cleans the deposited impurities on the inner wall of the aggregate ring 6 to ensure the centrifugal separation effect.

[0021] One side of the lower end of the collecting ring 6 is evenly provided with discharge ports 14, and a collecting frame 15 is connected to the lower end of the collecting ring 6 corresponding to multiple discharge ports 14. One side of the collecting frame 15 is connected to one side of the inner wall of the treatment tower 1, and the lower part of one side of the collecting frame 15 is connected to a discharge pipe 16, one end of the discharge pipe 16 extends through to one side of the treatment tower 1, and the lower part of the inner wall of the treatment tower 1 is connected to a water filter plate 17, and the cross-sectional shape of the water filter plate 17 is V-shaped. A discharge pipe 18 is connected to the middle part of the lower end of the water filter plate 17, and one end of the discharge pipe 18 extends through to one side of the treatment tower 1.

[0022] The scraper block 13 scrapes the impurities inside the collecting ring 6 to the discharge port 14, and the impurities are discharged through multiple discharge ports 14 and fall into the collecting frame 15. The collecting frame 15 is made of a filter mesh material, which is convenient for the sewage in the impurities to drip downward. At the same time, both sides of the lower end of the inner wall of the collecting frame 15 are connected with guide blocks, which can guide the material inside the collecting frame 15 to the discharge pipe 16 for discharge. At the same time, the sewage falls to the filter plate 17 after centrifugal treatment and flows downward after filtration. At the same time, when the second scraper 12 cleans the bottom of the baffle 7 and the bottom of the guide cover 2, the scraped impurities fall above the filter plate 17. The impurities above the filter plate 17 can be processed through the discharge pipe 18, and at the same time, efficient centrifugal impurity removal in the sewage pretreatment stage is realized.

[0023] A first cleaning pipe 19 is connected to one side of the treatment tower 1, and one end of the first cleaning pipe 19 extends through the interior of the treatment tower 1. The first cleaning pipe 19 is in an L-shaped structure. A first cleaning nozzle is evenly connected to the upper part of one side of the first cleaning pipe 19. A second cleaning pipe 20 is connected to the upper part of one side of the first cleaning pipe 19. The shape of the second cleaning pipe 20 is inclined. The second cleaning pipe 20 is located on one side above the centrifugal disk 5, and a second cleaning nozzle is connected to the lower end of the second cleaning pipe 20.

[0024] After long-term use, since the second scraper 12 scrapes the baffle 7 and the bottom of the air guide cover 2, impurities on the baffle 7 can fall directly and will not adhere to its surface, while impurities are likely to remain above the centrifugal disc 5 and on the outer wall of the first scraper 11. One end of the first cleaning pipe 19 is connected to the water pipe, and water enters the second cleaning pipe 20 through the first cleaning pipe 19. The water inside the first cleaning pipe 19 and the water inside the second cleaning pipe 20 are respectively sprayed to the upper surface of the centrifugal disc 5 and one side of the inner wall of the treatment tower 1 through the first cleaning nozzle and the second cleaning nozzle. When the centrifugal disc 5 rotates, multiple places on its surface can be cleaned. At the same time, when the gear ring 10 and the first scraper 11 rotate to one side of the first cleaning pipe 19, the outer wall of the first scraper 11 can be flushed, reducing the workload of disassembly and cleaning for the staff.

[0025] like Figure 8 、 9 As shown, the lower part of the inner wall of the treatment tower 1 is connected to a connecting cylinder 21, the lower part of the inner wall of the connecting cylinder 21 is connected to a first filter plate 22, the lower end of the first filter plate 22 is connected to a material changing pipe, and the outer wall of the material changing pipe is connected to a material changing valve, which can replace the activated carbon particles. The upper part of the inner wall of the connecting cylinder 21 is connected to the second filter plate 23, and the leveling mechanism includes a shell 24 and a leveling arm 34. There are two groups of shells 24, and the middle part of the lower end of the inner wall of the two shells 24 is connected to a cylinder 25. The lower ends of the two cylinders 25 extend through and extend to the lower ends of the two shells 24 respectively, and the lower ends of the two cylinders 25 are connected to movable plates 26. A cylinder 27 is connected between the two movable plates 26, and the upper end of the cylinder 27 is connected to a guide block. The shapes of the two sides of the upper end of the guide block are inclined, and the lower end of the inner wall of the cylinder 27 is connected to a water guide ring, and the shape of the water guide ring is V-shaped.

[0026] Activated carbon particles are filled into the interior of the connecting cylinder 21 and can be supported by the first filter plate 22. When the activated carbon layer is flushed by water for a long time, local depressions, gaps or crookedness may occur, causing the sewage to pass directly without sufficient contact with the activated carbon, thereby affecting the sewage treatment effect. A plurality of monitoring probes are arranged circumferentially below the second filter plate 23 to monitor whether there is any abnormality in the height of the activated carbon layer. When uneven height occurs, the two cylinders 25 push the movable plate 26 and the cylinder 27 downward, and then move the rotating tube 33 and the leveling arm downward, and the activated carbon particles are leveled by the leveling arm.

[0027] The outer wall of the treatment tower 1 is connected to an annular tube 28, one side of the upper end of the annular tube 28 is connected to a water pipe, and both sides of the inner wall of the annular tube 28 are connected to hoses 29, one end of the two hoses 29 extends through the inside of the treatment tower 1, and one end of the two hoses 29 is connected to a high-pressure nozzle 30, one end of the two high-pressure nozzles 30 extends through the inside of the cylinder 27, and the two high-pressure nozzles 30 are located on both sides of the cylinder 27. The middle part of the upper end of the inner wall of the cylinder 27 is rotatably connected to a rotating shaft 31, and the outer wall of the rotating shaft 31 is circumferentially connected to a rotating blade 3 2. The lower end of the rotating shaft 31 is connected to a rotating tube 33. The lower end of the rotating tube 33 extends through the cylinder 27 and the second filter plate 23 in sequence and extends to the lower end of the second filter plate 23. The upper portion of the outer wall of the rotating tube 33 is circumferentially provided with a water inlet 35. The lower end of the rotating tube 33 is connected to a leveling arm 34. The upper portion of one side of the leveling arm 34 is connected to a connecting tube 36. One side of the connecting tube 36 is evenly connected to a connecting nozzle 37. The lower portion of one side of the annular tube 28 is connected to a fixed tube 38. The lower end of the fixed tube 38 extends through the interior of the connecting tube 36.

[0028] During the leveling process, water enters the annular pipe 28 through the water pipe, and the water inside the annular pipe 28 is respectively transported to two high-pressure nozzles 30 through two hoses 29. The two high-pressure nozzles 30 are symmetrically arranged and spray the rotating blades 32 respectively. The rotating blades 32 rotate under the strong water pressure, thereby driving the rotating shaft 31 to rotate. During the rotation of the rotating shaft 31, the rotating pipe 33 and the leveling arm 34 are driven to rotate, which can scrape the activated carbon particles inside the connecting cylinder 21 to ensure the flatness of the activated carbon particles. At the same time, under the influence of the water guide ring, the water inside the cylinder 27 is concentrated in the middle of the lower inner wall of the cylinder 27, and the water enters the rotating pipe 33 through multiple water inlets 35. The water inside the rotating pipe 33 is transported to the inside of the connecting pipe 36 through the fixed pipe 38, and then the water is sprayed out through multiple connecting nozzles 37 on one side of the multiple connecting pipes 36 to achieve the flushing of the activated carbon particles on the surface, and can wash away the fine impurities and broken activated carbon particles on the surface.

[0029] Working principle: When in use, sewage flows into the V-shaped deflector 2 through the water inlet pipe 3. The deflector 2 concentrates the sewage to the middle of the centrifugal disc 5. The driving motor 4 drives the centrifugal disc 5 to rotate at high speed. Under the action of centrifugal force, the suspended matter such as silt and fiber in the sewage is thrown to the inner wall of the treatment tower 1 because its density is greater than that of water, and slides along the wall to the collecting ring 6; the liquid sewage is thrown out from the edge of the centrifugal disc 5 and falls. The cleaning motor 8 drives the gear 9 to rotate, and the gear 9 is engaged with the gear ring 10, so that the first scraper 11, the second scraper 12 and the scraper The scraper 13 rotates synchronously, and the second scraper 12 scrapes off impurities attached to the outer wall of the guide cover 2 and under the baffle 7. The first scraper 11 scrapes impurities from the inner wall of the treatment tower 1 to the collection ring 6. The scraper 13 cleans the impurities deposited on the inner wall of the collection ring 6. Then, the scraper 13 scrapes the impurities in the collection ring 6 to the discharge port 14, and falls into the collection frame 15. The sewage in the collection frame 15 drips and the material is discharged through the discharge pipe 16; the sewage after centrifugal treatment falls to the water filter plate 17, is filtered by it, and continues to flow downward. The impurities on the water filter plate 17 are discharged through the discharge pipe 18; After long-term use, impurities are likely to remain on the upper surface of the centrifugal disc 5 and the outer wall of the first scraper 11. The first cleaning pipe 19 is connected to the water pipe. Water passes through the first cleaning pipe 19 and the second cleaning pipe 20 respectively and is sprayed from the first cleaning nozzle and the second cleaning nozzle. When the centrifugal disc 5 rotates and the gear ring 10 and the first scraper 11 rotate to the corresponding positions, they are flushed, thereby reducing the workload of manual cleaning.

[0030] The connecting cylinder 21 is filled with activated carbon particles and supported by the first filter plate 22. The monitoring probe under the second filter plate 23 monitors the height of the activated carbon layer in real time. When unevenness occurs, the two cylinders 25 push the movable plate 26 and the cylinder 27 downward, driving the rotating tube 33 and the leveling arm 34 to descend. Water enters the annular pipe 28 through the water pipe and is then transported to the high-pressure nozzle 30 through the hose 29. The high-pressure nozzle 30 sprays strong water pressure on the rotating blades 32, causing the rotating blades 32 to drive the rotating shaft 31 to rotate, thereby driving the rotating tube 33 and the leveling arm 34 to rotate, scraping and leveling the activated carbon particles. In addition, the water in the cylinder 27 is concentrated at the lower part under the action of the water guide ring, enters the rotating tube 33 through the water inlet 35, and is then transported to the connecting pipe 36 through the fixed pipe 38, and finally sprayed out by the connecting nozzle 37 to rinse the surface of the activated carbon particles and wash off fine impurities and broken small particles. The sewage after centrifugal separation, activated carbon adsorption and leveling and flushing continues to flow downward in the treatment tower 1, and is deeply purified through multi-layer filtration and adsorption, and is finally discharged from the bottom of the treatment tower 1, achieving sewage treatment that meets the standards.
