Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and particularly to a sewage treatment and reuse device. Background Art

[0002] The resource utilization of sewage refers to removing harmful substances in sewage through advanced technical means, while recovering and utilizing the water resources and useful substances therein to achieve the reuse of wastewater. This technology can not only alleviate the problem of water resource shortage, but also reduce environmental pollution and promote the development of circular economy.

[0003] Currently, the following problems still exist in the existing technologies:

[0004] 1. In traditional sewage treatment methods, a grid is set up to intercept and remove larger floating objects and suspended solids in sewage, such as paper scraps and plastics. However, the grid is easily blocked by suspended solids during long-term use, so the grid needs to be removed and cleaned, which affects the sewage treatment efficiency. Moreover, when removing suspended solids, it is difficult to collect them centrally, so secondary collection is required, wasting time.

[0005] 2. During sewage treatment, it is necessary to remove inorganic particles with a larger density in sewage, such as sand grains and gravel, through gravitational sedimentation to prevent these substances from wearing out equipment or affecting the treatment effect in subsequent processes. After long-term use of the filter mesh cylinder, manual cleaning is required to maintain normal use. At the same time, it is also necessary to remove the oil stains floating on the top layer of the sewage, so a variety of decontamination devices need to be set up for hierarchical treatment, resulting in a complex decontamination process. Moreover, if the settled sand grains are not cleaned in time, the sand and gravel will accumulate continuously in the grit chamber, causing the sludge layer at the bottom of the sedimentation tank to gradually thicken, thereby reducing the sedimentation efficiency and affecting the treatment effect of wastewater.

[0017] The technical solution provided by this application has at least the following technical effects or advantages:

[0018] 1. Due to the adoption of the first water purification component, it effectively solves the problems in the traditional sewage treatment method. In the traditional method, a grille is set to intercept and remove larger floating objects and suspended solids in the sewage, such as paper scraps and plastics. However, the grille is easily blocked by suspended solids after long-term use, so it needs to be removed and cleaned, which affects the sewage treatment efficiency. And when removing suspended solids, it is difficult to collect them centrally, so secondary collection is required, wasting time. In this invention, the first water purification component can remove larger floating objects and suspended solids in the sewage. At the same time, when the grille bars are blocked, it can be automatically flushed under water pressure, and the floating objects and suspended solids are collected centrally. When the collection box reaches a certain weight, an alarm can be issued to remind the staff to clean, improving the sewage treatment efficiency.

[0019] 2. Due to the adoption of the second water purification component, it effectively solves the problems in sewage treatment. When treating sewage, it is necessary to remove inorganic particles with larger density in the sewage, such as sand grains and gravel, through gravity sedimentation to prevent these substances from wearing the equipment or affecting the treatment effect in subsequent treatment. However, the filter mesh cylinder needs to be cleaned manually after long-term use to maintain normal use. At the same time, it is necessary to remove the oil stains floating on the top layer of the sewage, so multiple decontamination devices need to be set for hierarchical treatment, resulting in a complex decontamination process. And if the sedimented sand grains are not cleaned in time, the sand and gravel will accumulate continuously in the grit chamber, causing the sludge layer at the bottom of the sedimentation tank to gradually thicken, reducing the sedimentation efficiency and affecting the treatment effect of the wastewater. In this invention, the second water purification component can improve the sedimentation effect of particulate impurities in the sewage, collect and treat them centrally, avoid the sludge layer at the bottom of the sewage treatment tank from gradually thickening and affecting the treatment effect of the wastewater. At the same time, it can remove the oil stains in the sewage, adjust the oil stain removal mechanism appropriately according to the height of the sewage liquid level, and collect the oil stains centrally. In addition, the filter mesh cylinder can be cleaned to maintain its long-term use. Description of the Drawings

Detailed implementation manners

[0036] For the grille, it is prone to being blocked by suspended substances during long-term use. The present invention can remove large floating objects and suspended substances in sewage through the first water purification component, and can automatically flush under water pressure when the grille bars are blocked. For the filter screen cylinder, it needs to be manually cleaned after long-term use to maintain normal operation. The present invention can improve the sedimentation effect of particulate impurities in sewage through the second water purification component, collect and process them centrally, avoid the gradual thickening of the sludge layer at the bottom of the sewage treatment tank, and affect the treatment effect of wastewater. At the same time, it can remove oil stains in sewage, clean the filter screen cylinder, and maintain the long-term use of the filter screen cylinder.

[0037] In order to better understand the above technical solutions, the following will describe the above technical solutions in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0038] Please refer to Figure 1 and Figure 2As shown in the figure, a sewage treatment and reuse device includes a sewage treatment tank 1. A first water purification component 2 is arranged on the outer surface of the sewage treatment tank 1, and a second water purification component 3 is arranged in the inner cavity of the sewage treatment tank 1. A partition 4 is fixedly installed in the middle of the inner wall of the sewage treatment tank 1. The middle part of the partition 4 is hollowed out. The partition 4 divides the inner part of the sewage treatment tank 1 into two parts, a first reservoir 5 and a second reservoir 6. The second water purification component 3 is located in the inner cavity of the first reservoir 5. The sewage is passed into the first water purification component 2 to remove larger floating objects and suspended matters, and is settled by the second water purification component 3 to remove sand and gravel particles in the sewage, as well as the oil stains suspended on the top layer of the sewage. Moreover, the first water purification component 2 and the second water purification component 3 can be self-cleaned. The treated sewage flows from the first reservoir 5 through the middle of the partition 4 into the inner cavity of the second reservoir 6. A water pump can be placed in the inner cavity of the second reservoir 6, and the water in the inner cavity of the second reservoir 6 is pumped out by the water pump for subsequent treatment and subsequent reuse.

[0039] Please refer to Figure 3 and Figure 4 As shown in the figure, the first water purification component 2 includes a water purification tank 21. Scum removal grooves 22 are opened on both sides of the water purification tank 21. A shielding block 23 is fixedly installed on the inner wall of the water purification tank 21. The upper surface of the shielding block 23 is flush with the bottom end of the scum removal groove 22. A grille frame 24 is arranged above the shielding block 23. The grille frame 24 is slidably connected to the water purification tank 21. Pressure mechanisms 25 are arranged on the inner walls on both sides of the water purification tank 21. The bottom end of the water purification tank 21 is communicated with a first water inlet pipe 26. The water purification tank 21 is fixedly connected to the sewage treatment tank 1. A collection box 27 is slidably connected to the outer surface of the sewage treatment tank 1. The water purification tank 21 is located above the inner cavity of the collection box 27. An alarm mechanism 28 is arranged at the bottom end of the collection box 27. The wastewater flows into the inner cavity of the water purification tank 21 from the first water inlet pipe 26, and larger floating objects and suspended matters are blocked by the grille frame 24, so that the larger floating objects and suspended matters are left at the bottom end of the grille frame 24. When the larger floating objects and suspended matters block the bottom end of the grille frame 24, with the continuous flow of water in the first water inlet pipe 26, the water flow will exert pressure on the grille frame 24, causing the grille frame 24 to move upward. At this time, the bottom end of the grille frame 24 moves away from the scum removal groove 22, enabling the water flow to flow towards the scum removal groove 22. At the same time, the water flow impacts the bottom end of the grille frame 24 during the flowing process, taking away the larger floating objects and suspended matters at the bottom end of the grille frame 24. At this time, under the pressure of the pressure mechanism 25, the grille frame 24 returns to its original position, allowing the water to pass through the grille frame 24, thus achieving the effect of removing larger floating objects and suspended matters. At the same time, the collection box 27 is used to collect larger floating objects and suspended matters, and sewage accumulates in the inner cavity of the collection box 27 during the collection process. As the weight increases, the alarm mechanism 28 issues an alarm to remind the staff to maintain the equipment for the normal operation of the equipment. The sewage on the water purification tank 21 enters the second water purification component 3 for further impurity removal.

[0040] Please refer to Figure 4 and Figure 5 As shown, the pressure mechanism 25 includes a fixed frame 251. A fixed rod 252 is fixedly installed on the inner wall of the fixed frame 251. The outer surfaces of both ends of the fixed rod 252 are slidably connected with a sliding frame 253. One end of the sliding frame 253 is rotatably connected with a connecting bar 254. The end of the connecting bar 254 away from the sliding frame 253 is rotatably connected with a pressure plate 255. A first spring 256 is sleeved on the outer surface of the fixed rod 252. A first threaded rod 257 is rotatably connected to the inner wall of the fixed frame 251. An adjusting block 258 is sleeved on the outer surface of the first threaded rod 257. There are two adjusting blocks 258. The pressure plate 255 is in close contact with the top end of the grille frame 24. The bottom end of the grille frame 24 has evenly arranged grille bars and is in contact with the shielding block 23 at the bottom end. The adjusting block 258 is slidably connected with the fixed frame 251. The adjusting block 258 is threadedly connected with the first threaded rod 257, and the thread directions at both ends of the first threaded rod 257 are opposite. The adjusting block 258 is slidably connected with the fixed rod 252. The first spring 256 is located between the adjusting block 258 and the sliding frame 253. The sliding frame 253 is slidably connected with the fixed frame 251. The pressure mechanism 25 is used to provide a flexible extrusion force to the grille frame 24. By rotating the first threaded rod 257, the adjusting block 258 moves on the first threaded rod 257. The movement of the adjusting block 258 drives the adjusting block 258 to squeeze the first spring 256, that is, by moving the adjusting block 258, the pressure of the first spring 256 on the sliding frame 253 is changed. The compression of the first spring 256 by the adjusting block 258 changes the pressure on the grille frame 24, ensuring the exposure of the slag removal tank 22 when the grille frame 24 is blocked and the shielding during dredging. When the grille frame 24 is blocked by a blockage, the grille frame 24 exerts an extrusion force on the pressure plate 255 under the water pressure. At this time, the connecting bar 254 rotates to drive the sliding frame 253 to slide on the fixed rod 252, and the first spring 256 contracts, reducing the distance between the pressure plate 255 and the fixed frame 251, so that the grille frame 24 moves upward, allowing water to flow into the inner cavity of the collection box 27 in the slag removal tank 22. During the flowing process, the floating objects and suspended matters at the bottom end of the grille frame 24 are washed, achieving the self-cleaning effect of the grille frame 24. At the same time, under the elastic force of the first spring 256, the pressure plate 255 squeezes the grille frame 24 so that the grille frame 24 comes into contact with the shielding block 23 again and shields the slag removal tank 22 to prevent water from entering the inner cavity of the collection box 27. Under the shielding of the grille frame 24, the floating objects and suspended matters in the sewage cannot pass above the grille frame 24, realizing the removal of the floating objects and suspended matters in the sewage.

[0041] Please refer to Figure 4 、 Figure 6 and Figure 7As shown, the alarm mechanism 28 includes a first fixed block 281 which is fixedly connected to the sewage treatment tank 1. A pressure rod 282 is fixedly installed at the bottom end of the collection box 27. A second spring 283 is sleeved on the outer surface of the pressure rod 282. An adjusting rod 284 is fixedly installed on the inner wall of the first fixed block 281. An adjusting plate 285 is sleeved on the outer surface of the adjusting rod 284. An extrusion ring 286 is fixedly installed at the top end of the adjusting plate 285. A hand-pulling block 287 is fixedly installed at the bottom end of the adjusting plate 285. A limiting groove 288 is formed on the outer surface of the adjusting plate 285. A sixth spring 289 is sleeved on the outer surface of the adjusting rod 284. A button 2810 is arranged on the lower surface of the collection box 27. A horn 2811 is arranged on the lower surface of the collection box 27. The button 2810 and the horn 2811 are electrically connected, and pressing the button 2810 controls the horn 2811 to emit an alarm. The extrusion ring 286 is located directly below the button 2810. There are eight limiting grooves 288. The part between the limiting grooves 288 is partially hollowed out, and the hollowed-out part is smaller than the diameter of the limiting groove 288. The two ends of the adjusting rod 284 near the inner wall of the first fixed block 281 are hollowed out. The adjusting plate 285 can slide up and down on the adjusting rod 284 under the pull of the hand-pulling block 287. The sixth spring 289 is located between the inner wall of the first fixed block 281 and the adjusting plate 285. The limiting groove 288 is slidably connected to the adjusting rod 284. The second spring 283 is located between the collection box 27 and the first fixed block 281. The pressure rod 282 is slidably connected to the first fixed block 281. When removing floating objects and suspended matters, when flushing the floating objects and suspended matters at the bottom end of the grille 24, water and impurities accumulate in the inner cavity of the collection box 27. Under the gravity of the water and impurities, the collection box 27 drives the pressure rod 282 to move downward in the inner cavity of the first fixed block 281, and the second spring 283 contracts under the pressure of the collection box 27. At this time, the extrusion ring 286 exerts pressure on the button 2810, causing the horn 2811 to emit an alarm, reminding the staff that they can maintain the sewage in the inner cavity of the collection box 27, facilitating the subsequent normal operation of the equipment. At the same time, it can also remind that when the grille 24 is blocked for a long time and cannot be cleaned, and when the floating objects and suspended matters at the bottom end of the grille 24 cannot be flushed, the collection box 27 is continuously weighted, and it can also remind the staff to maintain and clean the grille 24. The alarm weight can be set by adjusting the height of the extrusion ring 286, so as to prevent the sewage in the inner cavity of the collection box 27 from overflowing without an alarm according to the actual situation, and also prevent the collection box 27 from emitting an alarm when there is a little sewage and impurities. By pulling the hand-pulling block 287 to drive the adjusting plate 285 to slide on the adjusting rod 284, the sixth spring 289 is compressed, so that the hollowed-out part of the limiting groove 288 is in contact with the hollowed-out part of the adjusting rod 284, facilitating the up and down sliding of the adjusting plate 285, thereby changing the height of the extrusion ring 286. When adjusted to the appropriate position, release the hand-pulling block 287, and the limiting groove 288 and the adjusting rod 284 are kept fixed equal under the elastic force of the sixth spring 289.Thus, by adjusting the height of the extrusion ring 286, the alarm time can be controlled.

An adjustment mechanism 36 is sleeved on the outer surface of the filter screen cylinder 32. A dust removal mechanism 37 is arranged at the bottom end of the sedimentation hopper 33. The second water inlet pipe 34 is placed above the grid frame 24, facilitating the sedimentation of sand and gravel and oil removal from the sewage after removing floating objects and suspended matters. By the operation of the motor 353, the rotating rod 351 rotates in the inner cavity of the top cover 31, and the rotation of the belt 352 drives the rotating rod 351 to rotate. The sewage enters the inner cavity of the filter screen cylinder 32 from the second water inlet pipe 34. The rotation of the rotating rod 351 can clean the filter screen cylinder 32, sediment the sand and gravel at the same time, and skim the oil stains on the top layer of the sewage. The sand and gravel enter the dust removal mechanism 37 through the sedimentation hopper 33 for centralized cleaning. The water treated by the second water purification component 3 enters the second reservoir 6 from the partition plate 4, facilitating further high-level decontamination according to requirements or direct reuse.

The adjusting ring 3561 is slidably connected to the rotating rod 351. An oil skimming bar 3562 is fixedly installed on the outer surface of the adjusting ring 3561. A connecting frame 3563 is fixedly installed on the outer surface of the adjusting ring 3561. A plug rod 3564 is slidably connected to the inner cavity of the connecting frame 3563. A third spring 3565 is sleeved on the outer surface of the plug rod 3564. A fixing ring 3566 is fixedly installed on the outer surface of the plug rod 3564. A jack 3567 is opened on the outer surface of the rotating rod 351. The plug rod 3564 passes through the adjusting ring 3561 and is inserted into the jack 3567. The third spring 3565 is located between the fixing ring 3566 and the connecting frame 3563. The adjusting mechanism 36 includes a collecting tray 361. A connecting ring 362 is fixedly installed on the upper surface of the collecting tray 361. The top end of the connecting ring 362 is lower than the top end of the collecting tray 361. A groove 363 is opened in the connecting ring 362. Second fixing blocks 364 are fixedly installed on both sides of the top cover 31. A second threaded rod 365 is threadedly connected to the inner cavity of the second fixing block 364. A limiting rod 366 is slidably connected to the inner cavity of the second fixing block 364. The bottom end of the second threaded rod 365 is rotatably connected to the bottom wall of the collecting tray 361. The limiting rod 366 is fixedly connected to the collecting tray 361. The connecting ring 362 is slidably connected to the filter screen cylinder 32. The height of the oil skimming bar 3562 is flush with the groove 363. When removing sand and oil, the motor 353 drives the belt 352 to rotate. The rotation of the belt 352 drives the rotating rod 351 to rotate. The rotation of the rotating rod 351 drives the cleaning brush 354 and the turbine fan blade 355 to rotate. The cleaning brush 354 is used to clean the inner wall of the filter screen cylinder 32 to prevent a small number of sand particles from blocking the filter screen cylinder 32. The rotation of the turbine fan blade 355 causes the water flow to generate a certain centrifugal force. Since the density of sand particles is usually greater than that of water, the effect of the centrifugal force on sand particles is more significant. Therefore, under the action of gravity and centrifugal force, the sand quickly settles to the bottom end of the settling hopper 33. The oil skimming mechanism 356 is used to skim off oil stains so that the oil stains are centrally collected in the adjusting mechanism 36. By rotating the second threaded rod 365, the distance between the collecting tray 361 and the second fixing block 364 changes, that is, the height of the connecting ring 362 is changed, so that the top end of the connecting ring 362 is flush with the oil stains at the top of the sewage. At this time, by pulling the plug rod 3564, the plug rod 3564 is disengaged from the jack 3567,Move the position of the movable adjusting ring 3561 on the rotating rod 351. When it reaches the appropriate position, release the insertion rod 3564. Under the elastic force of the third spring 3565, drive the fixed ring 3566 to move towards the jack 3567, so that the insertion rod 3564 is inserted into the jack 3567 again, thereby changing the height of the adjusting ring 3561, making the height of the oil skimming bar 3562 flush with the height of the groove 363. When the rotating rod 351 rotates, it drives the oil skimming bar 3562 to rotate, so that the oil stains suspended at the top of the sewage are skimmed into the inner cavity of the collection tray 361 through the groove 363 under the rotation of the oil skimming bar 3562, so that the oil stain mixture is collected in the inner cavity of the collection tray 361, achieving the effect of removing the oil stain mixed impurities in the sewage. The effects of sand particle dust reduction, cleaning the filter screen cylinder 32 and removing oil stains are controlled by a single motor 353.,

[0044] Please refer to Figure 13 、 Figure 14 and Figure 15As shown in the figure, the dust removal mechanism 37 includes a dust removal box 371. The dust removal box 371 is fixedly connected to the sewage treatment tank 1. A dust removal cylinder 372 is slidably connected to the inner cavity of the dust removal box 371. One end of the dust removal cylinder 372 is fixedly connected to a slide plate 373, and the other end of the dust removal cylinder 372 is fixedly connected to a first baffle 374. A second baffle 375 is slidably connected to the inner cavity of the first baffle 374. The upper surface of the second baffle 375 is flush with the upper surface of the dust removal cylinder 372. A first convex rod is slidably connected to the bottom wall of the first baffle 374. A fourth spring is arranged in the inner cavity of the first convex rod. A first card slot is arranged at the bottom of the second baffle 375. The first convex rod is engaged with the first card slot. A second card slot is arranged on the upper surface of the second baffle 375. A second convex rod is arranged on the inner wall of the top end of the dust removal box 371, and the second convex rod is located on the side close to the slide plate 373. A fifth spring is arranged in the inner cavity of the second convex rod. When the second baffle 375 moves, the second convex rod is engaged with the second card slot. When the sand and gravel particles settle in the inner cavity of the settling hopper 33, they are centrally collected through the dust removal mechanism 37. The dust removal cylinder 372 is aligned with the bottom of the settling hopper 33. The slide plate 373 is pulled regularly to make the dust removal cylinder 372 move in the inner cavity of the dust removal box 371. At this time, the second baffle 375 blocks the bottom end of the settling hopper 33 to prevent the sand and gravel particles and sewage from entering the inner cavity of the dust removal box 371. At the same time, when the dust removal cylinder 372 is pulled to the outside of the sewage treatment tank 1, the sand and gravel particles leak out from the bottom end of the dust removal cylinder 372, thereby removing the sand and gravel particles, preventing the sand and gravel from accumulating at the bottom of the settling hopper 33, and avoiding affecting the sewage treatment. When the second baffle 375 blocks the bottom end of the settling hopper 33, first, the movement of the dust removal cylinder 372 drives the first baffle 374 to move. When the first baffle 374 moves to the position of the second convex rod, the second convex rod is engaged with the second card slot on the upper surface of the second baffle 375. At this time, the first convex rod is disengaged from the first card slot, so that the second baffle 375 slides on the first baffle 374, ensuring that the second baffle 375 can always block the bottom end of the settling hopper 33 when the dust removal cylinder 372 moves.

[0045] In summary, the sewage enters the first water purification component 2 to remove larger floating objects and suspended solids, and undergoes sedimentation through the second water purification component 3 to remove sand and gravel particles in the sewage, as well as the oil stains suspended on the top layer of the sewage. Moreover, the first water purification component 2 and the second water purification component 3 can self-clean. The treated sewage flows through the middle of the partition 4 from the first reservoir 5 into the inner cavity of the second reservoir 6. A water pump can be placed in the inner cavity of the second reservoir 6, and the water in the inner cavity of the second reservoir 6 is pumped out through the water pump for subsequent treatment and for subsequent reuse. The wastewater flows into the inner cavity of the water purification tank 21 from the first water inlet pipe 26, and the larger floating objects and suspended solids are blocked by the grid frame 24, so that the larger floating objects and suspended solids are left at the bottom end of the grid frame 24. When the larger floating objects and suspended solids block the bottom end of the grid frame 24, with the continuous flow of water in the first water inlet pipe 26, the water flow will exert pressure on the grid frame 24, causing the grid frame 24 to move upward. At this time, the bottom end of the grid frame 24 moves away from the slag removal groove 22, allowing the water flow to flow towards the slag removal groove 22. At the same time, the water flow impacts the bottom end of the grid frame 24 during the flowing process, carrying away the larger floating objects and suspended solids at the bottom end of the grid frame 24. At this time, under the pressure of the pressure mechanism 25, the grid frame 24 returns to its original position, enabling the water to pass through the grid frame 24, thereby achieving the effect of removing larger floating objects and suspended solids. Meanwhile, the collection box 27 is used to collect larger floating objects and suspended solids, and sewage accumulates in the inner cavity of the collection box 27 during the collection process. As the weight increases, the alarm mechanism 28 issues an alarm to remind the staff to maintain the equipment. The sewage enters the inner cavity of the filter screen cylinder 32 from the second water inlet pipe 34. The decontamination mechanism 35 rotates to clean the filter screen cylinder 32, and at the same time, sedimentation of sand and gravel can be carried out, as well as skimming of the oil stains on the top layer of the sewage. The sand and gravel enter the dust removal mechanism 37 through the sedimentation hopper 33 for centralized cleaning. The water treated by the second water purification component 3 enters the second reservoir 6 through the partition 4, achieving the sewage decontamination effect and facilitating subsequent reuse.
