Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and more specifically, to a circulating treatment aeration oxidation pond and method. Background Art

[0002] Aeration refers to the process of forcing oxygen in the air to transfer into the liquid. Its purpose is to obtain sufficient dissolved oxygen and strengthen the contact between organic matter, microorganisms and dissolved oxygen in the pool, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] The document with the prior art publication number CN213171802U provides a circulating aeration oxidation pond for sewage treatment, which performs secondary treatment on the treated sewage through the filter tank, thereby improving the treatment quality, and the sewage that does not meet the standards flows into the sewage treatment pond through the circulating treatment pipe for further treatment, achieving the effect of circulating treatment, thereby enhancing the sewage treatment effect; the sludge plate is flushed by extracting the treated clean water, and then the sludge is pumped out of the sewage treatment pond by the suction pump for treatment, thereby increasing the efficiency of sewage cleaning and reducing the cost and waste of resources caused by multiple sewage cleaning. Although the above device can clean the bottom sludge in the pond through the sludge plate and the suction pump, it is relatively slow to use the cleaning nozzle to flush the sludge on the cleaning plate, which affects the working efficiency of the sewage aeration oxidation pond; furthermore, the sewage treatment pond and the filter tank have different volumes. When the filter tank is working, the sewage treatment pond has not been emptied, resulting in other sewage being unable to enter the sewage treatment pond for treatment, which reduces the efficiency of sewage treatment.

[0004] In view of this, we propose a circulating treatment aeration oxidation pond and method. Summary of the invention

[0018] In the above technical solution, the silt clearing mechanism and the lifting mechanism can be moved, so as to achieve a comprehensive cleaning effect on the sludge at the bottom of the sewage pool 1 and improve the cleaning quality.

[0019] As an optional solution of the technical solution of the present application document, the lifting mechanism includes a lifting gear column 601, a lifting motor 602, a lifting gear 604, a chain 607 and a connecting rod 608. The driving end of the lifting motor 602 and one end of the connecting rod 608 are both provided with sprockets 603. The sprockets 603 are connected by a chain 607. The side wall of the connecting rod 608 is sleeved with a lifting gear 604, and the lifting gear column 601 is meshed and arranged on the outer side of the lifting gear 604.

[0020] By adopting the above technical solution, while the sewage inside the sedimentation tank 2 is still, the lifting motor 602 can be started to make the sprocket 603 start to rotate, and one of the sprockets 603 drives the connecting rod 608 to rotate, and the connecting rod 608 drives the lifting gear 604 to rotate, thereby driving the lifting gear column 601 to rise or fall.

The lifting slide plate 504 is slidably arranged on the top side of the walking bracket 4, and the dredging pump 5 is fixedly arranged on the top side of the walking bracket 4.

[0024] In the above technical solution, the lifting tooth column 601 drives the connection plate 505 to move up and down, thereby realizing the lifting and down of the dredging mechanism. The lifting and down of the connection plate 505 drives the lifting and down of the lifting slide plate 504 at the same time, so as to maintain the stability of the dredging mechanism.

A pawl 701 is meshed on the outer side of the ratchet 7, and a spring 702 is fixedly provided on one side of the pawl 701. The pawl 701 is fixedly provided at one end of the electric telescopic rod 703.

[0026] In the above technical solution, when the lifting gear column 601 descends, the electric telescopic rod 703 pushes the pawl 701 to compress the spring 702, so that the pawl 701 is disengaged from the meshing with the ratchet 7, so that the ratchet 7 can rotate and the lifting gear 604 can rotate; when the dredging mechanism reaches the dredging position, the electric telescopic rod 703 is used to restore the pawl 701 to the engaged state with the ratchet 7 to prevent the lifting gear column 601 from descending when the dredging mechanism is working; and when the lifting gear column 601 rises, the spring 702 will be compressed, and the electric telescopic rod 703 will not be powered, and the ratchet 7 can move the pawl 701 when it rotates in the opposite direction; and the electric telescopic rod 703 can be freely extended and retracted, so that the pawl 701 is easy to be moved, so as to achieve a self-locking effect, prevent the lifting gear column 601 from falling, and protect the dredging mechanism.

[0028] In the above technical solution, the rotation of the connecting rod 608 will drive the ratchet 7 to rotate, and the rotation of the ratchet 7 will drive the pawl 701 to rotate.

[0029] As an optional solution of the technical solution of this application document, the sludge conveying pipe 502 is connected and arranged on the top side of the sludge pool 3, and the volumes of the sewage pool 1 and the sedimentation pool 2 are the same.

[0030] In the above technical solution, new sewage can continue to be aerated and oxidized while sewage is settling, thereby improving the efficiency of sewage treatment.

[0031] The present invention also aims to provide a method for circulating aeration treatment, comprising the following steps:

[0032] The sewage is poured into the sewage pool 1 from the sewage inlet 101, and the air pump 103 is started to extract the outside air and transport the oxygen in the air to the sewage through the aeration pipe 104 to achieve the effect of aeration and oxidation;

[0033] After the sewage is aerated and oxidized, the pump between the sewage tank 1 and the sedimentation tank 2 pumps the treated sewage into the sedimentation tank 2.

[0034] The filter plate inside the sedimentation tank 2 blocks impurities from floating to the upper layer inside the sedimentation tank 2. After the impurities in the water are settled, the clean water inside the sedimentation tank 2 can be pumped out through the outlet pump on one side of the sedimentation tank 2.

[0035] The lifting motor 602 is started to drive the connecting rod 608 to rotate, the connecting rod 608 drives the lifting gear 604 to rotate, and the lifting gear 604 drives the lifting gear column 601 to descend, thereby realizing the synchronous descending of the silt removal mechanism. When the lifting gear column 601 descends, the electric telescopic rod 703 pushes the pawl 701 to compress the spring 702, so that the pawl 701 is disengaged from the ratchet 7, and the ratchet 7 is unlocked and drives the lifting gear 604 to rotate;

[0036] When the silt removal mechanism reaches the silt removal position, the pawl 701 resumes the engagement state with the ratchet wheel 7 to prevent the lifting tooth column 601 from continuing to descend when the silt removal mechanism is working;

[0037] When the sludge suction nozzle 508 is about to touch the bottom of the sewage pool 1, it stops. At this time, the silt removal claw on one side of the bottom end of the auxiliary claw plate 506 contacts the bottom of the sewage pool 1, and the silt removal pump 5 is turned on. The sludge passes through the sludge suction nozzle 508, the sludge suction pipe 507, the second telescopic pipe 503, the silt removal pump 5, the first telescopic pipe 501 and the sludge conveying pipe 502 in sequence and enters the sludge pool 3, which is convenient for centralized treatment later;

[0038] When the silting mechanism is running, the travel motor 401 is started to drive the travel support 4 to start moving, thereby driving the lifting mechanism and the silting mechanism to move to clean the silt at the bottom of the sewage pool 1;

[0039] After the silt is cleared into the sludge pool 3 by the silt removal mechanism, sewage is continuously poured into the sewage pool 1 for aeration and oxidation treatment.

[0040] 3. Beneficial effects

[0041] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0042] 1. In this application, the cooperation of the lifting mechanism and the silting mechanism is adopted to effectively solve the problem of low silting efficiency. While quickly and cleanly cleaning the silt at the bottom of the sewage pool, it also improves the effect of sewage aeration treatment;

[0043] 2. In this application, the lifting mechanism can realize the lifting and lowering of the dredging mechanism. When the dredging mechanism is lowered, the bottom of the sewage pool can be dredged. When the dredging mechanism stops working, the lifting mechanism can drive the dredging mechanism to rise, so that the dredging mechanism will not be exposed to too much silt, thereby reducing the aging rate of the dredging mechanism;

[0044] 3. In this application, the silt removal mechanism can suck out the silt at the bottom of the sewage pool through the silt suction nozzle, and the silt removal claw can loosen the silt to facilitate the suction of the silt suction nozzle, thereby improving the quality and efficiency of silt removal;

[0045] 4. In the present application, the self-locking mechanism can prevent the lifting gear column from continuing to descend when not in use, so as to prevent the dredging mechanism from falling or descending too fast, thereby causing damage to the dredging mechanism, thereby achieving a better protection effect on the dredging mechanism.

[0096] While the sewage inside the sedimentation tank 2 is at rest, the lifting mechanism can be turned on, and the lifting motor 602 in the lifting mechanism is started, so that the sprocket 603 starts to rotate, and the two sprockets 603 are driven by the chain 607, one of the sprockets 603 drives the connecting rod 608 to rotate, and the connecting rod 608 drives the lifting gear 604 to rotate, and the lifting gear 604 can drive the lifting gear column 601 to rise or fall, and the falling of the lifting gear column 601 can make the connecting plate 505 fall, so that the dredging mechanism falls, and when the sludge suction nozzle 508 is about to touch the bottom end of the sewage tank 1, it stops. At this time, the dredging claw on one side of the bottom end of the auxiliary claw plate 506 contacts the bottom end of the sewage tank 1, so that the dredging mechanism is close to the sludge for dredging.

[0097] Reference Figure 6 and Figure 8 A self-locking mechanism is provided on one side of the fixed platform A6, and the self-locking mechanism includes a ratchet 7, a pawl 701, a spring 702 and an electric telescopic rod 703.

[0098] When the lifting gear column 601 descends, the electric telescopic rod 703 in the self-locking mechanism will push the pawl 701, so that the spring 702 will be compressed, so that the pawl 701 will leave the meshing with the ratchet 7, so that the ratchet 7 can rotate, so that the lifting gear 604 can rotate. When the dredging mechanism reaches the dredging position, the pawl 701 is restored to the engaged state with the ratchet 7 to prevent the lifting gear column 601 from descending when the dredging mechanism is working. When the lifting gear column 601 is raised, the spring 702 will be compressed, and the electric telescopic rod 703 will not be energized, so that the ratchet 701 can be moved when the ratchet 7 rotates in the opposite direction, and the electric telescopic rod 703 can be freely extended and retracted, so that the pawl 701 is moved, thereby achieving a self-locking effect, preventing the lifting gear column 601 from falling, and protecting the dredging mechanism.

[0099] Reference Figure 1 and Figure 3 The sludge conveying pipe 502 is fixedly arranged on one side of the top of the sludge pool 3, and the volumes of the sewage pool 1 and the sedimentation pool 2 are the same.

[0100] In this way, new sewage can continue to be aerated and oxidized while the sewage is settling, and the two processes can be carried out simultaneously to improve the efficiency of sewage treatment.

[0101] It is worth noting that the following steps are included:

[0102] S1. First, sewage can be poured into the sewage pool 1 from the sewage inlet 101;

[0103] S2, then the air pump 103 draws in the outside air, and transports the oxygen in the air to the sewage through the aeration pipe 104, so as to achieve the effect of aeration and oxidation;

[0104] S3. After the sewage aeration and oxidation is completed, the treated sewage will be pumped into the interior of the sedimentation tank 2 by the pump between the sewage tank 1 and the sedimentation tank 2. The filter plate inside the sedimentation tank 2 can prevent impurities from floating to the upper layer inside the sedimentation tank 2. Then, it will be left to stand for a period of time to wait for the impurities in the water to settle, and then the clean water inside the sedimentation tank 2 can be pumped out by the outlet pump on one side of the sedimentation tank 2.

[0105] S4, lifting mechanism, the lifting motor 602 in the lifting mechanism is started, so that the sprocket 603 starts to rotate, and the two sprockets 603 are driven by the chain 607, one of the sprockets 603 drives the connecting rod 608 to rotate, and the connecting rod 608 drives the lifting gear 604 to rotate, and the lifting gear 604 can drive the lifting gear column 601 to rise or fall, so that the dredging mechanism rises or falls;

[0106] S5. When the lifting gear column 601 descends, the electric telescopic rod 703 in the self-locking mechanism will push the pawl 701, so that the spring 702 will be compressed, so that the pawl 701 will leave the meshing with the ratchet 7, so that the ratchet 7 can rotate, so that the lifting gear 604 can rotate. When the dredging mechanism reaches the dredging position, the pawl 701 can be restored to the engaged state with the ratchet 7 to prevent the lifting gear column 601 from descending when the dredging mechanism is working. When the lifting gear column 601 rises, the spring 702 will be compressed, and the electric telescopic rod 703 will not be energized, so that the ratchet 701 can be moved when the ratchet 7 rotates in the opposite direction, and the electric telescopic rod 703 can be freely extended and retracted, so that the pawl 701 is moved, so as to achieve the effect of self-locking, prevent the lifting gear column 601 from falling, and protect the dredging mechanism;

[0107] S6, when the sludge suction nozzle 508 is about to touch the bottom of the sewage pool 1, it stops. At this time, the dredging claw on one side of the bottom end of the auxiliary claw plate 506 contacts the bottom of the sewage pool 1, and then the dredging pump 5 is turned on. The sludge can be sucked into the sludge suction pipe 507 by the sludge suction nozzle 508, and then passes through the second telescopic pipe 503 and the dredging pump 5 to enter the first telescopic pipe 501. The second telescopic pipe 503 is convenient for the lifting and lowering of the sludge suction pipe 507, and the first telescopic pipe 501 is convenient for the movement of the dredging pump 5. Then, the sludge inside the first telescopic pipe 501 can enter the interior of the sludge pool 3 through the sludge conveying pipe 502 for collection, which is convenient for centralized treatment at a later stage;

[0108] S7. When the silt removal mechanism is running, the travel motor 401 is started to rotate the travel gear 404, thereby driving the travel support 4 to start moving, and the moving wheel A405 and the moving wheel B406 will roll on the top of the fixed tooth plate 402 and the track plate 403, thereby driving the lifting mechanism and the silt removal mechanism to move and clean the silt at the bottom of the sewage pool 1, so that the silt at the bottom of the sewage pool 1 can be cleaned more comprehensively. After the silt removal mechanism cleans the silt into the silt pool 3, sewage can continue to be poured into the sewage pool 1 for aeration and oxidation treatment, and it will not affect the static treatment of sewage in the sedimentation tank 2, so that the efficiency of sewage treatment can be improved.

[0109] Working principle: Sewage is poured into the interior of the sewage tank 1 from the sewage inlet 101, and then the air pump 103 draws in the outside air, and the oxygen in the air is transported to the sewage through the aeration pipe 104 to achieve the effect of aeration oxidation. After the aeration and oxidation of the sewage is completed, the treated sewage will be pumped into the interior of the sedimentation tank 2 by the water pump between the sewage tank 1 and the sedimentation tank 2. The filter plate inside the sedimentation tank 2 can prevent impurities from floating to the upper layer inside the sedimentation tank 2, and then stand for a period of time, waiting for the impurities in the water to settle, and then the clean water inside the sedimentation tank 2 can be pumped out through the outlet pump on one side of the sedimentation tank 2. The vent valve 201 can balance the air pressure inside the sedimentation tank 2. When the sewage in the sedimentation tank 2 is at rest, the lifting mechanism can be turned on, and the lifting motor 602 in the lifting mechanism is started, so that the sprocket 603 starts to rotate, and the two sprockets 603 are driven by the chain 607, one of the sprockets 603 drives the connecting rod 608 to rotate, and the connecting rod 608 drives the lifting gear 604 to rotate, and the lifting gear 604 can drive the lifting gear column 601 to rise or fall, and when the lifting gear column 601 falls, the electric telescopic rod 703 in the self-locking mechanism will push the pawl 701, so that the spring 702 will be compressed, so that the pawl 701 will leave the meshing with the ratchet 7, so that the ratchet 7 can rotate to make the lifting gear column 601 rise or fall. The wheel 604 can rotate, and when the silting mechanism reaches the silting position, the pawl 701 can be restored to the engaged state with the ratchet 7 to prevent the lifting gear column 601 from falling when the silting mechanism is working. When the lifting gear column 601 is raised, the spring 702 will be compressed, and the electric telescopic rod 703 will not be energized, so that the ratchet 701 can be moved when the ratchet 7 rotates in the opposite direction, and the electric telescopic rod 703 can be freely extended and retracted, so that the pawl 701 can be moved, thereby achieving a self-locking effect, preventing the lifting gear column 601 from falling, and protecting the silting mechanism. The falling of the lifting gear column 601 can cause the connecting plate 505 to fall, thereby causing the silting mechanism to fall. When the sludge suction nozzle 508 is about to touch the bottom of the sewage pool 1, it stops. At this time, the silt removal claw on one side of the bottom end of the auxiliary claw plate 506 contacts the bottom of the sewage pool 1. Then the silt removal pump 5 is turned on. The sludge can be sucked into the sludge suction pipe 507 by the sludge suction nozzle 508, and then passes through the second telescopic pipe 503 and enters the first telescopic pipe 501 through the silt removal pump 5. The second telescopic pipe 503 is convenient for the lifting and lowering of the sludge suction pipe 507, and the first telescopic pipe 501 is convenient for the movement of the silt removal pump 5. Then, the sludge inside the first telescopic pipe 501 can enter the interior of the sludge pool 3 through the sludge conveying pipe 502 for collection, which is convenient for centralized treatment at a later stage.

[0110] At the same time, the travel motor 401 is started to make the travel gear 404 start to rotate, thereby driving the travel bracket 4 to start moving, and the moving wheel A405 and the moving wheel B406 will roll on the top of the fixed tooth plate 402 and the track plate 403, thereby driving the lifting mechanism and the dredging mechanism to move to clean the sludge at the bottom of the sewage pool 1, so that the sludge at the bottom of the sewage pool 1 can be cleaned more comprehensively. After the dredging mechanism cleans the sludge into the sludge pool 3, sewage can continue to be poured into the sewage pool 1 for aeration and oxidation treatment, and it will not affect the static treatment of sewage in the sedimentation tank 2, so that the efficiency of sewage treatment can be improved.

Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
