Description

Technical Field

[0001] The invention relates to the technical field of aeration, in particular to a liftable microporous aerator. Background Art

[0002] Aerators are usually installed at the bottom of sewage treatment tanks to increase the dissolved oxygen content in sewage by diffusing air or pure oxygen, and are often used in activated sludge method to treat sewage. This method is to continuously mix and culture sewage and various microbial communities under conditions of artificial oxygenation and aeration to form activated sludge. The biological coagulation, adsorption and oxidation effects of activated sludge are used to decompose and remove organic pollutants in sewage. The sludge is then separated from the water. Most of the sludge is returned to the aeration tank, and the excess is discharged from the activated sludge system.

[0003] Considering that the activated sludge method is usually used for sewage treatment in the prior art, the prior art often clogs the aerator due to gravity sedimentation of flocculent activated sludge before use, thereby affecting the efficiency of aeration. At the same time, since the activated sludge method will increase the activated sludge in the aeration tank, the prior art usually discharges the excess activated sludge after sewage treatment. However, due to the long activated sludge treatment time, part of the activated sludge may sink to the bottom and adhere to the bottom of the aeration tank during this period, which will increase the time and manpower required for cleaning the aeration tank. After multiple treatments, the bottom of the aeration tank will be filled with activated sludge. If the aerator is at the bottom of the aeration tank at this time, it may also cause complete blockage of the aerator. Summary of the invention

[0010] Furthermore, the interiors of the first adjusting block and the second adjusting block are both hollow and connected to each other, and the first adjusting block and the second adjusting block are both connected to the air guide block.

[0015] 3. The present invention can make the blocked aeration holes of the microporous aerators be dredged by high pressure, thereby reducing the microporous aerators that need to be replaced, increasing economic benefits, and at the same time reducing the time required for replacing the microporous aerators, so that the aeration process is not interrupted, and increasing the sewage treatment efficiency.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 8 As shown, the present invention is a liftable microporous aerator, comprising a lifting plate 1, a gas delivery unit is fixedly connected to the bottom of the lifting plate 1, a plurality of aeration units 2 are fixedly connected to the end of the gas delivery unit away from the lifting plate 1, and the gas delivery unit is used to deliver air into the aeration unit 2; both sides of the lifting plate 1 close to the gas delivery unit are fixedly connected to extension plates, a sliding groove is provided at the bottom of the extension plate, a lifting unit 3 is slidably connected in the sliding groove, and the lifting unit 3 is fixedly connected to the two outermost aeration units 2; The aeration unit 2 includes two air guide blocks 22, and an air equalizing tube 21 is fixedly connected between the air guide blocks 22; a plurality of microporous aerators 25 are fixedly connected to the bottom of the air equalizing tube 21; the aeration holes of the microporous aerator 25 are arranged downward, and the side of the microporous aerator 25 away from the air equalizing tube 21 is made of elastic and flexible material, the microporous aerators 25 are evenly arranged in a fan shape, and there are multiple groups of the fan-shaped microporous aerators 25 arrayed along the air equalizing tube 21.

[0021] In this embodiment, it is considered that the activated sludge method is usually used to treat sewage in the prior art. Before the prior art is used, the flocculent activated sludge often clogs the aerator due to gravity precipitation, thereby affecting the efficiency of aeration. At the same time, since the activated sludge method will increase the activated sludge in the aeration tank, the prior art usually discharges the excess activated sludge after sewage treatment. However, due to the long activated sludge treatment time, part of the activated sludge may sink to the bottom and adhere to the bottom of the aeration tank during this period, which will increase the time and manpower required for cleaning the aeration tank. After multiple treatments, the bottom of the aeration tank will be filled with activated sludge. If the aerator is at the bottom of the aeration tank at this time, it may also cause the aerator to be completely blocked; When the sewage needs to be aerated, the aeration unit 2 is placed in the sewage through the lifting unit 3. When the aeration unit 2 is placed at the designated position, air can be input into the air guide pipe through the air delivery unit, and the air is transferred to the air equalizing pipe 21 through the air guide pipe. When the air equalizing pipe 21 is full of air, the sewage is aerated through the microporous aerator 25. Since the aeration holes of the microporous aerator 25 are arranged downward, when the microporous aerator 25 aerates the sewage, it also aerates the water at the bottom of the aeration unit 2. When the air flows out of the aeration holes, it pushes the surrounding sewage at the same time, thereby causing the sewage to fluctuate. When the sewage fluctuates, it drives the activated sludge in the sewage to flow, which can prevent the activated sludge from sinking to the bottom. When the aeration unit 2 is close enough to the bottom of the aeration tank, the flow of sewage is pushed by aeration, so that the sewage can impact the bottom of the aeration tank. When the sewage impacts the bottom of the aeration tank, the activated sludge that has sunk to the bottom can be refloated, and the activated sludge that adheres to the bottom can be broken up and refloated, so that the activated sludge can contact more sewage, thereby increasing the efficiency of sewage treatment. In addition, since the aeration unit 2 can break up the activated sludge that adheres to the bottom of the aeration tank, the time and manpower required for cleaning the aeration tank can be reduced. In the existing equipment for aeration from the bottom to the top, since the aerator and the pipe itself have a certain thickness, and the aerator cannot completely prevent the activated sludge from sinking to the bottom, during upward aeration, the activated sludge below the aerator and adhering to the bottom of the aeration tank cannot be aerated. After long-term use, the activated sludge will continue to accumulate and eventually cover the aerator and the pipe. When the activated sludge sinks to the bottom, it will not only reduce the efficiency of sewage treatment, but also increase the manpower and time required for subsequent cleaning. Since the microporous aerators 25 are arranged in a fan shape, a larger range of sewage can be oxygenated during sewage treatment, and a larger range of activated sludge can be pushed to prevent the activated sludge from sinking to the bottom; since the side of the microporous aerator 25 away from the air equalizing tube 21 is elastic and made of flexible material, when the microporous aerator 25 contacts the bottom of the aeration tank, the flexible material will be used for buffering to prevent deformation caused by rigid contact between the aeration unit 2 and the aeration tank; at the same time, when contacting the bottom, the microporous aerator 25 at the bottom may be blocked due to excessive deposition of activated sludge at the bottom of the aeration tank. At this time, the air pressure inside the air equalizing tube 21 will increase, and excess air will be ejected from the unblocked microporous aerator 25, which will push the activated sludge on the bottom of the aeration tank to be turned over and the activated sludge that has sunk to the bottom will float again, thereby making the sewage treatment more efficient, and the turning of the water flow at the bottom of the aeration tank by continuous aeration can prevent the activated sludge from sinking to the bottom or attaching again.

[0022] Specifically, the gas supply unit includes two aeration pumps 11, which are fixedly connected to the two sides of the bottom of the lifting plate 1, and the aeration pump 11 is fixedly connected to a plurality of gas supply hoses 12; a gas supply hole 221 is opened on the side of the gas guide block 22 away from the gas equalizing pipe 21, and the gas supply hole 221 is fixedly connected to the gas supply hose 12.

[0023] In this embodiment, considering that the aerator may be blocked during aeration, the existing equipment usually lifts the aeration unit 2 out of the water surface as a whole through the lifting unit 3 after being blocked, and handles the blocked aerator through manual inspection, and then re-aerates. Since some aerators are only blocked on the surface, it is only necessary to scrape off the activated sludge on the surface of the aerator, but the manual inspection will take a certain amount of time, during which the sewage in the aeration tank will not be aerated, which will reduce the treatment efficiency; During aeration, the aeration pump 11 is started to allow air to enter the air guide block 22 through the air delivery hose 12, and the air is introduced into the air equalizing pipe 21 through the air guide pipe. When the air equalizing pipe 21 is full of air, the sewage is aerated through the microporous aerator 25. When the microporous aerator 25 is blocked, the two aeration pumps 11 are started at the same time to increase the aeration pressure. When the pressure increases, the activated sludge on the surface of the microporous aerator 25 is washed down, so that the microporous aerator 25 can be re-aerated. Since there are two aeration pumps 11, the two aeration pumps 11 can be turned on at the same time after the activated sludge increases, thereby increasing the input air, allowing more activated sludge to come into contact with oxygen, and increasing the sewage treatment efficiency.

[0024] Specifically, both sides of the inner wall of the gas equalizing pipe 21 are fixedly connected with limit rings 23 , and the inner wall of the gas equalizing pipe 21 is sealingly and slidably connected with sliding blocks 24 , and the sliding blocks 24 are located between the limit rings 23 .

[0025] In this embodiment, considering that the aerator may encounter blockage caused by activated sludge penetrating into the aeration holes, usually the air pressure is increased to try to flush out the sludge. If it cannot be flushed out, the aerator needs to be replaced. When the microporous aerator 25 is blocked, the aeration pump 11 on one side is started. Since the space in the air equalizing tube 21 of the sliding block 24 is small before the sliding block 24 moves, when air is input through the aeration pump 11, the sliding block 24 will rapidly increase the air pressure on the side close to the aeration pump 11, so that the local air pressure increases. At this time, the high-pressure air flows out of the microporous aerator 25 to dredge the blocked aeration holes, and the air input through the aeration pump 11 will cause the sliding block 24 to be pushed by the air. When the sliding block 24 moves, the air is always entering the air equalizing tube 21, so the air pressure inside the air equalizing tube 21 is always high, thereby enabling all the microporous aerators 25 to dredge the blocked aeration holes through high pressure, thereby reducing the number of microporous aerators 25 that need to be replaced, increasing economic benefits, and at the same time reducing the time required to replace the microporous aerators 25, so that the aeration process is not interrupted, and the sewage treatment efficiency is increased. The sliding block 24 can be made to slide back and forth by cyclically using the aeration pumps 11 on both sides. Since one side of the sliding block 24 is aerated while the other side is not aerated, the sewage will fluctuate back and forth. At this time, the activated sludge in the sewage will be more evenly distributed due to the fluctuation of the sewage, thereby making the sewage treatment efficiency higher.

[0026] Specifically, the inner wall of the gas equalizing pipe 21 is symmetrically fixedly connected with a guide rail 231, the guide rail 231 is located between the limiting rings 23, and the guide rail 231 is sealingly slidably connected to the sliding block 24, and the guide rail 231 is used to prevent the sliding block 24 from flipping over.

[0027] In this embodiment, it is considered that when only one side of the sliding block 24 is pressurized, excessive air pressure may cause the sliding block 24 to flip, thereby making it impossible to handle the clogged aerator; The guide rail 231 can be provided to enable the sliding block 24 to move according to the guide rail 231 , and can prevent the sliding block 24 from turning over due to excessive air pressure, thereby avoiding the microporous aerator 25 that cannot be properly processed due to blockage.

[0028] Specifically, an adjustment unit 4 is fixedly connected between adjacent aeration units 2; the adjustment unit 4 includes a first adjustment block 41 and a second adjustment block 42, and the first adjustment block 41 is slidably connected to the inner wall of the second adjustment block 42; installation grooves 222 are provided on both sides of the air guide block 22, and the installation grooves 222 are fixedly connected to the first adjustment block 41 and the second adjustment block 42 respectively, and the first adjustment block 41 is located on the right side of the second adjustment block 42.

[0029] In this embodiment, considering that the prior art can only aerate sewage at a fixed position when in use, the efficiency of sewage treatment by activated sludge in the area not aerated may be low, and the activated sludge may sink to the bottom and adhere; During aeration, the spacing between the aeration units 2 can be adjusted by setting the first adjustment block 41 and the second adjustment block 42, so as to achieve aeration of sewage at multiple locations, so that the aeration range is larger and the efficiency of sewage treatment is increased; When the aeration pump 11 on one side is started to allow air to push the sliding block 24, the sliding block 24 will cause air to escape from one side of the air equalizing pipe 21 but not from the other side. This will cause the air blown out from both sides of the air equalizing pipe 21 to be uneven and to move through the first adjustment block 41 and the second adjustment block 42 of the air guide block 22 on the same side, causing the air equalizing pipe 21 to tilt. When the sliding block 24 moves to the extreme position and the aeration pump 11 on the other side is started, the air equalizing pipe 21 will also be tilted. This will allow the air equalizing pipe 21 to swing back and forth in the sewage, which can not only expand the scope of sewage treatment, but also prevent activated sludge from sinking to the bottom and adhering to the bottom, thereby increasing the sewage treatment efficiency and reducing the time and manpower required for subsequent cleaning.

[0030] Specifically, the first adjusting block 41 and the second adjusting block 42 are both hollow inside and are connected to each other. The first adjusting block 41 and the second adjusting block 42 are both connected to the air guide block 22 .

[0031] In this embodiment, since the interiors of the first regulating block 41 and the second regulating block 42 are interconnected, when the pressure in some of the air equalizing pipes 21 is insufficient, the other air equalizing pipes 21 can introduce air through the first regulating block 41 and the second regulating block 42, so that the treatment efficiency of the aeration units 2 is the same, preventing the aeration efficiency from decreasing due to insufficient air pressure in some of the aeration units 2, and at the same time preventing the inability to normally break up the adhered activated sludge due to insufficient air pressure.

[0032] Specifically, the lifting unit 3 includes four support plates 32 and four lifting motors 31, the lifting motors 31 are slidably connected to the bottom of the extension plate, and the output ends of the lifting motors 31 are fixedly connected to the rotating shafts 33; the support plates 32 are slidably connected to the sliding grooves, and the surfaces of the support plates 32 are provided with rotating holes, and the rotating holes are rotatably connected to the rotating shafts 33; the outer wall of the rotating shaft 33 is fixedly connected to a steel cable 34, and the end of the steel cable 34 away from the rotating shaft 33 is fixedly connected to a fixing ring 35, and the inner wall of the fixing ring 35 is slidably connected to a lifting block 36, and the lifting block 36 is fixedly connected to the mounting groove 222 of the outermost air guide block 22.

[0033] In this embodiment, before aeration, the lifting motor 31 is started to drive the rotating shaft 33 to rotate, and the steel cable 34 on the rotating shaft 33 is dropped, and the steel cable 34 pulls the fixing ring 35 so that the lifting block 36 drives the air guide pipe to move, and the aeration unit 2 moves as a whole; When the aeration tank is replaced, the position of the support plate 32 and the lifting motor 31 can be adjusted to adjust the spacing between the aeration units 2. During the aeration process, aeration in a wider range can be achieved by adjusting the spacing between the aeration units 2. At the same time, the lifting motor 31 on one side can be adjusted to make the aeration unit 2 vibrate up and down during use, thereby increasing the aeration area in the vertical direction, which can solve the problem of no aeration above the aeration unit 2.

[0034] Specifically, a plurality of buckets 5 are evenly and fixedly connected to the bottom of the outer wall of the air equalizing pipe 21 , and a plurality of dispersion plates 51 are fixedly connected to the surface of one side of the bucket 5 away from the air equalizing pipe 21 .

[0035] In this embodiment, the bucket 5 is set up so that when the aeration pipe 21 is tilted or moved, the stubborn activated sludge at the bottom can be shoveled away by the bucket 5, and the activated sludge can be broken up by the dispersion plate 51 and aeration, so that the activated sludge can be used for sewage purification again, while reducing the time and manpower for subsequent cleaning of the aeration tank.

[0036] When using, First, before aeration, the lifting motor 31 is started to drive the rotating shaft 33 to rotate, and the steel cable 34 on the rotating shaft 33 is dropped, and the steel cable 34 pulls the fixing ring 35 to make the lifting block 36 drive the air guide pipe to move, and the aeration unit 2 moves as a whole; When the aeration tank is replaced, the positions of the support plate 32 and the lifting motor 31 can be adjusted, and the spacing between the aeration units 2 can be adjusted by setting the first adjustment block 41 and the second adjustment block 42, so as to achieve aeration of sewage in multiple positions, so that the aeration range is larger and the efficiency of sewage treatment is increased; during the aeration process, aeration in a larger range can be achieved by adjusting the spacing between the aeration units 2.

[0037] Secondly, during aeration, the aeration pump 11 is started to allow air to enter the air guide block 22 through the air hose 12, and the air is introduced into the air equalizing pipe 21 through the air guide pipe. When the air equalizing pipe 21 is full of air, the sewage is aerated through the microporous aerator 25; Since the aeration holes of the microporous aerator 25 are arranged downward, when the microporous aerator 25 aerates the sewage, it also aerates the water at the bottom of the aeration unit 2. When the air flows out of the aeration holes, it pushes the surrounding sewage at the same time, thereby causing the sewage to fluctuate. When the sewage fluctuates, it drives the activated sludge in the sewage to flow, which can prevent the activated sludge from sinking to the bottom. When the aeration unit 2 is close enough to the bottom of the aeration tank, the flow of sewage is pushed by aeration, so that the sewage can impact the bottom of the aeration tank. When the sewage impacts the bottom of the aeration tank, the activated sludge that has sunk to the bottom can be refloated, and the activated sludge that adheres to the bottom can be broken up and refloated, so that the activated sludge can contact more sewage, thereby increasing the efficiency of sewage treatment. In addition, since the aeration unit 2 can break up the activated sludge that adheres to the bottom of the aeration tank, the time and manpower required for cleaning the aeration tank can be reduced. Since the microporous aerator 25 is arranged in a fan shape, a larger range of sewage can be oxygenated during sewage treatment, and a larger range of activated sludge can be pushed to prevent the activated sludge from sinking to the bottom; Then, during aeration, the aeration pump 11 is started to allow air to enter the air guide block 22 through the air hose 12, and the air is introduced into the air equalizing pipe 21 through the air guide pipe. When the air equalizing pipe 21 is full of air, the sewage is aerated through the microporous aerator 25. When the microporous aerator 25 is blocked, the two aeration pumps 11 are started at the same time to increase the aeration pressure. When the pressure increases, the activated sludge on the surface of the microporous aerator 25 is washed down, so that the microporous aerator 25 can be re-aerated. Since there are two aeration pumps 11, the two aeration pumps 11 can be turned on at the same time when the activated sludge increases, so that the input air increases, so that more activated sludge can come into contact with oxygen, and the sewage treatment efficiency is increased. During aeration, By adjusting the lifting motor 31 on one side, the aeration unit 2 can be made to vibrate up and down during use, thereby increasing the aeration area in the vertical direction, thereby solving the problem that aeration cannot be carried out above the aeration unit 2.

[0038] Finally, when the microporous aerator 25 is blocked, the aeration pump 11 on one side is started. Since the space in the air equalizing tube 21 of the sliding block 24 is small before the sliding block 24 moves, when air is input through the aeration pump 11, the sliding block 24 will rapidly increase the air pressure on the side close to the aeration pump 11, so that the local air pressure increases. At this time, the high-pressure air flows out of the microporous aerator 25 to dredge the blocked aeration holes, and the air input through the aeration pump 11 will cause the sliding block 24 to be pushed by the air. When the sliding block 24 moves, the air is always entering the air equalizing tube 21, so the air pressure inside the air equalizing tube 21 is always high, thereby enabling all the microporous aerators 25 to dredge the blocked aeration holes through high pressure, thereby reducing the microporous aerators 25 that need to be replaced, increasing economic benefits, and at the same time reducing the time required to replace the microporous aerators 25, so that the aeration process is not interrupted, and the sewage treatment efficiency is increased. The sliding block 24 can be slid back and forth by cyclically using the aeration pumps 11 on both sides. Since one side of the sliding block 24 is aerated while the other side is not aerated, the sewage will fluctuate back and forth. At this time, the activated sludge in the sewage will be more evenly distributed due to the fluctuation of the sewage, thereby making the sewage treatment efficiency higher. When the aeration pump 11 on one side is started to make the air push the sliding block 24, the sliding block 24 will make one side of the air equalizing pipe 21 to release air, but the other side will not release air. Because the air blown out from both sides of the air equalizing pipe 21 is uneven, and moves through the first adjustment block 41 and the second adjustment block 42 of the air guide block 22 on the same side, the air equalizing pipe 21 is tilted. When the sliding block 24 moves to the extreme position and the aeration pump 11 on the other side is started, the air equalizing pipe 21 is also tilted. As a result, the air equalizing pipe 21 can be swung back and forth in the sewage, which can not only expand the scope of sewage treatment, but also prevent the activated sludge from settling to the bottom and adhering, thereby increasing the sewage treatment efficiency and reducing the time and manpower required for subsequent cleaning. By setting the bucket 5, the stubborn activated sludge at the bottom can be shoveled away by the bucket 5 when the aeration pipe 21 is tilted or moved, and the activated sludge can be broken up by the dispersion plate 51 and aeration, so that the activated sludge can be used for sewage purification again, while reducing the time and manpower for subsequent cleaning of the aeration tank.
