Description

Technical Field

[0001] The invention relates to the technical field of aeration tanks, in particular to an aeration tank with an anti-clogging structure for wastewater treatment. Background Art

[0002] Aeration is a means of bringing air and water into strong contact. Its purpose is to dissolve oxygen in the air into water, or to expel unwanted gases and volatile substances in water into the air. It is often used in wastewater treatment, and aeration tanks are a key component in wastewater treatment. Air is injected into wastewater through aerators to promote the activity of aerobic microorganisms, thereby decomposing organic matter and removing pollutants.

[0003] However, the prior art still has the following defects when used specifically: The aerator in the aeration tank is often clogged during wastewater treatment due to two problems. One is that the wastewater is not pretreated in the early stage, resulting in the presence of large particles in the wastewater. The other is that the fibrous material in the wastewater is not treated, resulting in the formation of a biofilm basis in the later stage. The above two situations will not only affect the wastewater treatment effect, but also cause the aerator to become clogged and reduce the service life of the aerator.

[0004] In view of this, the present invention proposes an aeration tank with an anti-clogging structure for wastewater treatment to compensate for and improve the shortcomings of the prior art. Summary of the invention

[0008] Furthermore, the outer wall of the rotating blade is evenly and fixedly connected with four rectangular frames in a rectangular orientation, and the number of the intercepting plates is the same as the number of the rectangular frames.

[0009] Furthermore, a detachable cover plate fixed by snapping is installed on the top of the rectangular frame, four collecting grooves are evenly opened on the top of the detachable cover plate, and the inner walls of the tops of the four collecting grooves are fixedly connected with diversion partitions.

[0010] Furthermore, the number of the removable cover plates is the same as the number of the rectangular frames, and the lengths of the four collecting troughs are consistent with the lengths of the four diversion partitions.

[0011] Furthermore, an auxiliary dosing mechanism is provided on the top of the aeration tank body and above the rotating blades, and the auxiliary dosing mechanism includes a bracket symmetrically fixedly connected to the top of the aeration tank body, a support beam is fixedly connected between the side walls of the two brackets, a funnel-shaped medicine storage box is fixedly connected to the inner wall of the top of the support beam and above the rotating blades, a transparent observation frame is fixedly connected to the bottom of the funnel-shaped medicine storage box, and the bottom end of the transparent observation frame passes through the inner wall of the bottom of the support beam, and a lower medicine cartridge is also fixedly connected to the bottom of the funnel-shaped medicine storage box and located inside the transparent observation frame, and the lower medicine cartridge is communicated with the interior of the funnel-shaped medicine storage box, a rocker arm is hinged to the inner wall of the bottom of the transparent observation frame, and a torsion spring is sleeved on the inner wall of the hinge of the rocker arm, and a sealing ball is fixedly connected to the top of the rocker arm, and the sealing ball is located directly below the bottom opening of the lower medicine cartridge.

[0012] Furthermore, the bottom end of the lower medicine cartridge matches the contour shape of the top end of the sealing ball, and two of the funnel-shaped medicine storage box, transparent observation frame, lower medicine cartridge, rocker arm and sealing ball are symmetrically arranged inside the support beam.

[0013] Furthermore, two arc-shaped drug guiding plates are symmetrically fixedly connected to the side wall of the rotating blade, and a precipitation plate is also fixedly connected to the outer wall of the rotating blade away from the rectangular frame. A plurality of reaction grooves are evenly arranged on the outer wall of the precipitation plate, and the number of the precipitation plates is the same as the number of the rotating blades.

[0014] Furthermore, a plurality of filter fences are evenly and fixedly connected to the inner wall of the water inlet on one side away from the support plate.

[0015] Furthermore, a collecting claw is hingedly connected to the outer wall of the water retaining plate on one side close to the supporting plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) When the rectangular frame is immersed in the wastewater between the water retaining plate and the water inlet, the wastewater is poured into the rectangular frame through the collecting trough and the leakage hole. The collecting trough is combined with the diversion baffle so that the openings on both sides of the collecting trough below the diversion baffle can be filled with wastewater, thereby increasing the amount of wastewater collected. At the same time, compared with the leakage hole, the length of the collecting trough is equal to that of the diversion baffle, which is more conducive to the filling of wastewater. When the poured wastewater is mixed with large particles, and combined with the leakage hole with a smaller diameter, the wastewater entering the rectangular frame will be discharged through the leakage hole when the rectangular frame rotates to the highest point of the rotating blade, while the large particles of the wastewater remain on the surface of the interception plate. At the same time, the drainage trough opened on the outer wall of the interception plate can facilitate the deposition of large particles under the action of their own gravity.

[0017] Among them, the elastic characteristics of the support spring are utilized to make the support spring shake during the rotation of the rotating blade. Combined with the height difference between the intercepting plate and the drain trough, large particles shake inside the drain trough, which facilitates the complete separation of large particles from wastewater and improves the collection efficiency of large particles. As the rotating blades continue to rotate, the four rectangular frames can circulate and collect large particles in the wastewater, significantly reducing the content of large particles in the wastewater, so that when the wastewater enters the aeration tank body and cooperates with the aerator for aeration, impurities will not affect the aerator, avoiding blockage, which not only improves the aeration effect of the wastewater, but also helps to increase the service life of the aerator.

[0018] (2) As the sealing ball moves away from the bottom opening of the lower medicine barrel, a gap appears at the connection between the sealing ball and the lower medicine barrel, so that the chemical agent inside the funnel-shaped medicine storage box can fall through the bottom opening of the lower medicine barrel to the surface of the arc-shaped medicine guide plate. The arc-shaped medicine guide plate can guide the chemical agent, which helps to divert the chemical agent to the wastewater on the side away from the transparent observation frame, and accelerate the combination and reaction of the chemical agent with the fiber material in the wastewater, thereby avoiding excessive concentration of the chemical agent in the wastewater below the transparent observation frame. As the rotating blades continue to stir the wastewater, the chemical agent and the wastewater combine more evenly, which can accelerate the removal of fiber material in the wastewater, thereby reducing the basis for subsequent biofilm formation and reducing the probability of blockage inside the aeration tank body and the aerator.

[0019] Among them, the time it takes for the arc-shaped drug guide plate to rotate one circle following the rotating blade is used as the interval length, which can achieve the purpose of intermittently putting chemical agents into the wastewater, making the use of chemical agents more scientific, reducing the amount of chemical agents used, and improving the effect of removing fiber substances in the wastewater.

[0020] (3) As the rotating blades rotate, part of the wastewater containing chemicals will fall onto the surface of the sedimentation plate and inside the reaction tank. When the sedimentation plate rotates to the highest point along with the rotating blades, the mixing time of the wastewater and chemicals remaining in the reaction tank can be extended. Increasing the reaction time can make the reaction more thorough, which is beneficial to improving the reaction effect.

[0021] (4) By setting up a removable cover plate and fixing it with a snap-on method, the removable cover plate is easy to remove, which is helpful to shorten the time consumed for maintenance. After the removable cover plate is removed, the interception plate fixed with bolts is removed by professional tools, so that the interception plate is separated from the lifting plate, and then it is convenient to remove the large particles collected on the surface of the interception plate for unified treatment, which helps to keep the surface of the interception plate clean. After reinstallation, it is convenient for next use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] 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.

[0025] Embodiments of the present invention: Please refer to Figures 1 to 9 As shown, an aeration tank with an anti-clogging structure for wastewater treatment includes an aeration tank body 1, a support plate 2 is fixedly connected to the inner wall at the top of the aeration tank body 1, an aerator 201 is fixedly connected to the bottom of the support plate 2, a water inlet 3 is opened on the inner wall at one end of the aeration tank body 1 away from the support plate 2, a water outlet 301 is opened on the inner wall at one end of the aeration tank body 1 close to the support plate 2, a water retaining plate 302 is fixedly connected to the inner wall at the bottom of the aeration tank body 1 close to the water inlet 3, and a pre-interception mechanism for collecting floating impurities and particulate matter in the wastewater is arranged inside the aeration tank body 1 and between the water retaining plate 302 and the water inlet 3.

[0026] The pre-interception mechanism includes a motor 401 fixedly connected to the outer wall of the aeration tank body 1, the output shaft end of the motor 401 passes through the inner wall of the aeration tank body 1 and is fixedly connected to a rotating blade 402, the end of the rotating blade 402 away from the motor 401 is rotatably connected to the inner wall of the aeration tank body 1, the top of the rotating blade 402 is fixedly connected to a rectangular frame 403, and a plurality of leakage holes 404 are provided around the outer wall of the rectangular frame 403, a support spring 405 is fixedly connected to the top of the rotating blade 402 and located inside the rectangular frame 403, a lifting plate 406 is fixedly connected to the top of the support spring 405, an interception plate 407 fixed by bolts is installed on the top of the lifting plate 406, and a plurality of drainage grooves 408 are evenly provided on the top of the interception plate 407, and four rectangular frames 403 are evenly fixedly connected to the outer wall of the rotating blade 402 in a rectangular orientation, and the number of interception plates 407 is the same as the number of rectangular frames 403.

[0027] When the rectangular frame 403 is immersed in the wastewater between the water retaining plate 302 and the water inlet 3, the wastewater is poured into the rectangular frame 403 through the collecting groove 502 and the leaking hole 404, and the collecting groove 502 is used in conjunction with the diversion baffle 503, so that the openings on both sides of the collecting groove 502 located below the diversion baffle 503 can be poured into the wastewater, thereby increasing the amount of wastewater collected. When the poured wastewater is mixed with large particles, and the leaking hole 404 with a smaller diameter is used, the wastewater entering the rectangular frame 403 is discharged through the leaking hole 404 when the rectangular frame 403 rotates to the highest point of the rotating blade 402, and the elastic support spring 405 is used to release the wastewater. The feature causes the support spring 405 to shake during the rotation of the rotating blade 402. Combined with the height difference between the intercepting plate 407 and the drain trough 408, large particles are shaken inside the drain trough 408, which facilitates the complete separation of large particles from wastewater and improves the collection efficiency of large particles. As the rotating blade 402 continues to rotate, the four rectangular frames 403 can circulate and collect large particles in the wastewater, significantly reducing the content of large particles in the wastewater, so that when the wastewater enters the aeration tank body 1 and cooperates with the aerator 201 for aeration, impurities will not affect the aerator 201, thereby avoiding blockage.

[0028] Preferably, a removable cover 501 fixed by snapping is also installed on the top of the rectangular frame 403, and four collecting grooves 502 are evenly arranged on the top of the removable cover 501. The inner walls of the tops of the four collecting grooves 502 are fixedly connected with diversion baffles 503. The number of removable cover 501 is the same as the number of rectangular frames 403, and the lengths of the four collecting grooves 502 are consistent with the lengths of the four diversion baffles 503.

[0029] Preferably, an auxiliary dosing mechanism is provided at the top of the aeration tank body 1 and above the rotating blades 402, and the auxiliary dosing mechanism includes a bracket 601 symmetrically fixedly connected to the top of the aeration tank body 1, a support beam 602 is fixedly connected between the side walls of the two brackets 601, a funnel-shaped medicine storage box 603 is fixedly connected to the inner wall of the top of the support beam 602 and above the rotating blades 402, and a transparent observation frame 604 is fixedly connected to the bottom of the funnel-shaped medicine storage box 603, and the bottom end of the transparent observation frame 604 passes through the inner wall of the bottom of the support beam 602, and the bottom of the funnel-shaped medicine storage box 603 and the transparent observation frame 604 are fixedly connected. 04 is also fixedly connected to a lower medicine cartridge 605, which is connected to the interior of the funnel-shaped medicine storage box 603. A rocker arm 606 is hingedly connected to the inner wall of the bottom of the transparent observation frame 604. A torsion spring is sleeved on the inner wall of the hinge of the rocker arm 606. A sealing ball 607 is fixedly connected to the top of the rocker arm 606. The sealing ball 607 is located just below the bottom opening of the lower medicine cartridge 605. The bottom end of the lower medicine cartridge 605 is consistent with the contour of the top end of the sealing ball 607. Two of the funnel-shaped medicine storage box 603, the transparent observation frame 604, the lower medicine cartridge 605, the rocker arm 606 and the sealing ball 607 are symmetrically arranged inside the support beam 602.

[0030] Among them, as the sealing ball 607 moves away from the bottom opening of the lower medicine barrel 605, a gap appears at the connection between the sealing ball 607 and the lower medicine barrel 605, so that the chemical agent inside the funnel-shaped medicine storage box 603 can fall through the bottom opening of the lower medicine barrel 605 to the surface of the arc-shaped medicine guide plate 701. The arc-shaped medicine guide plate 701 has a curved surface to guide the chemical agent, which helps to guide the chemical agent to the wastewater away from the transparent observation frame 604. It can accelerate the combination and reaction of the chemical agent with the fiber material in the wastewater, and avoid excessive concentration of the chemical agent in the wastewater below the transparent observation frame 604. As the rotating blades 402 continue to stir the wastewater, the chemical agent and the wastewater are combined more evenly, which can accelerate the removal of the fiber material in the wastewater, thereby reducing the basis for subsequent biofilm formation and reducing the probability of blockage inside the aeration tank body 1 and the aerator 201.

[0031] Preferably, two arc-shaped drug guiding plates 701 are symmetrically and fixedly connected to the side wall of the rotating blade 402, and a sedimentation plate 702 is also fixedly connected to the outer wall of the rotating blade 402 away from the rectangular frame 403. A plurality of reaction grooves 703 are evenly arranged on the outer wall of the sedimentation plate 702. The number of the sedimentation plates 702 is the same as the number of the rotating blades 402. A plurality of filter fences 801 are evenly and fixedly connected to the inner wall of the water inlet 3 away from the support plate 2, and a collecting claw 901 is hingedly connected to the outer wall of the water retaining plate 302 close to the support plate 2.

[0032] Among them, by setting a filter fence 801 inside the water inlet 3, large floating objects and garbage such as plant branches in the wastewater can be intercepted to prevent these garbage from entering the aeration tank body 1 and participating in the aeration reaction. It is also easy to cause blockage in the aerator 201, which has an adverse effect on wastewater treatment. At the same time, the garbage intercepted by the filter fence 801 can be conveniently collected and processed uniformly during daily maintenance by the staff.

[0033] The following are the complete usage steps and working principles of the above embodiment: When the device is in use, the staff discharges the wastewater to be treated into the interior of the aeration tank body 1 through the water inlet 3, so that the wastewater first flows into the space between the water retaining plate 302 and the water inlet 3. The water retaining plate 302 can be used to intercept the wastewater in a short period of time, preventing the wastewater from directly entering the interior of the aeration tank body 1, making it convenient for the subsequent addition of chemical agents to treat the wastewater. In addition, by arranging a filter fence 801 inside the water inlet 3, it is possible to intercept large floating objects and garbage such as plant branches in the wastewater, preventing these garbage from entering the interior of the aeration tank body 1 and participating in the aeration reaction. It is also easy to cause blockage of the aerator 201, which has an adverse effect on the wastewater treatment. At the same time, the garbage intercepted by the filter fence 801 can be conveniently collected and processed uniformly during daily maintenance by the staff.

[0034] Then the staff starts the motor 401 through the control panel, so that the output shaft end of the motor 401 rotates counterclockwise with the rotating blade 402, thereby causing the rectangular frame 403, the removable cover plate 501, etc. to rotate synchronously. When the rectangular frame 403 is immersed in the wastewater between the water retaining plate 302 and the water inlet 3, the wastewater is poured into the rectangular frame 403 through the collection tank 502 and the leakage hole 404, and the collection tank 502 is used in conjunction with the diversion baffle 503, so that the collection tank 502 is located below the diversion baffle 503. Wastewater can be poured into the openings on both sides, which increases the amount of wastewater collected. At the same time, compared with the leakage hole 404, the collection groove 502 is equal to the length of the diversion partition 503, which is more conducive to the injection of wastewater. When large particles are mixed in the injected wastewater, and the leakage hole 404 with a smaller diameter is combined, the wastewater entering the rectangular frame 403 will be discharged through the leakage hole 404 when the rectangular frame 403 rotates to the highest point of the rotating blade 402, while the large particles of wastewater remain on the surface of the interception plate 407, and at the same time, the wastewater is discharged from the surface of the interception plate 407. The drain trough 408 opened on the outer wall of the intercepting plate 407 can facilitate the sedimentation of large particles under the action of their own gravity. In addition, the intercepting plate 407 is fixed to the lifting plate 406 by bolts, and a supporting spring 405 is arranged at the bottom of the lifting plate 406. The elastic characteristics of the supporting spring 405 make the supporting spring 405 shake during the rotation of the rotating blade 402. Combined with the height difference between the intercepting plate 407 and the drain trough 408, the large particles shake inside the drain trough 408, which facilitates the complete separation of large particles from wastewater and improves the collection efficiency of large particles. With the continuous rotation of the rotating blade 402, the four rectangular frames 403 can circulate and collect large particles in the wastewater, significantly reducing the content of large particles in the wastewater, so that when the wastewater enters the aeration tank body 1 and cooperates with the aerator 201 for aeration, impurities will not affect the aerator 201, avoiding blockage, which not only improves the aeration effect of the wastewater, but also helps to increase the service life of the aerator 201.

[0035] When a large number of large particles are collected inside the rectangular frame 403, the staff is required to perform regular cleaning. By providing a removable cover 501 and fixing it with a snap-on method, the removable cover 501 is easy to remove, which is beneficial to shorten the time consumed for maintenance. After removing the removable cover 501, the interception plate 407 fixed with bolts is removed by professional tools, so that the interception plate 407 is separated from the lifting plate 406, and then the large particles collected on the surface of the interception plate 407 are taken out for unified treatment, which helps to keep the surface of the interception plate 407 clean. After reinstallation, it is convenient for next use.

[0036] In addition, when the wastewater is located between the water inlet 3 and the water retaining plate 302, due to the presence of fibrous substances in the wastewater, if it is not treated, biofilm is easily formed later, resulting in blockage of the aeration tank body 1 and the aerator 201. By adding chemical agents into the funnel-shaped medicine storage box 603, commonly used chemical agents include chlorine, ozone, hydrogen peroxide, etc., the arc-shaped medicine guide plate 701 is rotated by the rotating blade 402, so that the arc-shaped medicine guide plate 701 will collide with the bottom of the swing rod 606 every time it rotates one circle, and by pushing the bottom end of the swing rod 606, the swing rod 606 carries the sealing ball 607 The transparent observation frame 604 turns clockwise inside and squeezes the torsion spring on the inner wall of the hinge of the swing rod 606 at the same time. Since the top of the sealing ball 607 matches the bottom contour of the lower cartridge 605, the sealing ball 607 can fit tightly with the lower cartridge 605 in the initial state, thereby sealing the bottom opening of the lower cartridge 605 to prevent the chemicals from falling. As the sealing ball 607 moves away from the bottom opening of the lower cartridge 605, a gap appears at the connection between the sealing ball 607 and the lower cartridge 605, so that the chemicals in the funnel-shaped medicine storage box 603 can pass through The bottom opening of the lower medicine cartridge 605 falls onto the surface of the arc-shaped medicine guide plate 701. The arc-shaped medicine guide plate 701 can guide the chemical agent, which helps to guide the chemical agent to the wastewater away from the transparent observation frame 604. It can accelerate the combination and reaction of the chemical agent with the fiber material in the wastewater, and avoid excessive concentration of the chemical agent in the wastewater below the transparent observation frame 604. As the rotating blades 402 continue to stir the wastewater, the chemical agent and the wastewater are combined more evenly, which can accelerate the removal of the fiber material in the wastewater, thereby reducing the basis for subsequent biofilm formation and reducing The probability of blockage inside the aeration tank body 1 and the aerator 201 is reduced. When the arc-shaped drug guide plate 701 does not conflict with the bottom of the rocker arm 606, the rocker arm 606 is reset with the sealing ball 607 under the rebound effect of the torsion spring, and the bottom opening of the lower cartridge 605 is re-sealed. The time for the arc-shaped drug guide plate 701 to rotate one circle following the rotating blade 402 is used as the interval time, which can achieve the purpose of intermittently putting chemical agents into the wastewater, making the use of chemical agents more scientific, reducing the amount of chemical agents used, and improving the effect of removing fiber substances in the wastewater.

[0037] In addition, after the wastewater is combined with the chemical agent, as the rotating blades 402 rotate, part of the wastewater containing the chemical agent will fall on the surface of the sedimentation plate 702 and the inside of the reaction tank 703. When the sedimentation plate 702 rotates to the highest point along with the rotating blades 402, the mixing time of the wastewater and the chemical agent remaining in the reaction tank 703 can be extended. Increasing the reaction time can make the reaction more thorough, which is beneficial to improving the reaction effect. By setting the collecting claw 901, the wastewater after the fiber material is treated can be intercepted and collected for the second time, so as to prevent the garbage floating objects missed in the early stage from entering the aeration area of ​​the aerator 201 inside the aeration tank body 1. At the same time, the collecting claw 901 is hingedly arranged, so as to achieve the purpose of regularly collecting the garbage floating objects collected by the collecting claw 901. During operation, it is only necessary to flip the collecting claw 901 to the side of the rotating blade 402. Finally, the wastewater treated by aeration can be discharged from the outside of the aeration tank body 1 through the outlet 301.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
