[0002] Aeration tanks are a common wastewater treatment device in modern society. They can react with wastewater through biological characteristics, thereby reducing the presence of organic pollutants in the wastewater and making the wastewater meet discharge standards.

[0003] In current technology, aeration is a means of bringing air and water into strong contact. Usually, multiple sets of air pipes are installed at the bottom of the aeration tank, and air is generated by a blower and discharged through the aeration head to accelerate the reaction between sewage and air in the aeration tank.

[0004] During use, some wastewater enters the aeration tank. Due to the time required for the blower to start, some impurities gradually accumulate on the surface of the aeration head due to the sedimentation of the wastewater and the impact force generated when the wastewater enters, causing the aeration head to become clogged. Therefore, to address the above problem, an erosion-resistant aeration tank is proposed. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] 1. This invention provides an erosion-resistant aeration tank. By utilizing a guide plate installed on the top of the aeration head, the top of the aeration head can be protected under the support of a positioning plate, reducing the direct impact of water flow that causes impurities to enter and accumulate inside the aeration head, thus affecting the normal air circulation. At the same time, during the sedimentation stage, the tilting effect of the guide plate causes impurities to drift to the surrounding area of ​​the aeration head, reducing the accumulation of impurities in the aeration head.

[0017] 2. This invention provides an erosion-resistant aeration tank. By utilizing the blocking effect of the No. 2 and No. 1 baffle plates on the sewage, the outlet of the aeration head can be blocked during the subsequent static sedimentation of the sewage after reaction. This reduces the downward-falling impurities from obliquely bypassing the guide plate and entering the interior of the aeration head, maintaining the unobstructed flow inside the aeration head and reducing blockage.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5As shown, an erosion-resistant aeration tank includes an aeration tank 1; multiple sets of air pipes 11 are inherently located at the bottom of the aeration tank 1; multiple sets of aeration heads 12 are connected to the top of the air pipes 11; multiple sets of positioning plates 13 are fixedly connected to the top of the aeration heads 12; guide plates 14 are fixedly connected to the top of the positioning plates 13; the guide plates 14 are conical in shape and concave at the bottom; during operation, as sewage is treated inside the aeration tank 1, the guide plates 14 installed on the top of the aeration heads 12 can block the water flow, thereby dispersing the water flow to both sides until the entire aeration head 12 is submerged, and subsequently... In the static state of the wastewater, the impurities that gradually settle downwards will drift to the top of the guide plate 14. By tilting the top of the guide plate 14 downwards, the amount of impurities entering the aeration head 12 is reduced. This step utilizes the guide plate 14 installed on the top of the aeration head 12, which, with the support of the positioning plate 13, protects the top of the aeration head 12, reducing the direct impact of water flow that causes impurities to enter and accumulate inside the aeration head 12, thus affecting the normal air circulation of the aeration head 12. At the same time, during the sedimentation stage, the tilting effect of the guide plate 14 causes impurities to drift to the surrounding area of ​​the aeration head 12, reducing the accumulation of impurities in the aeration head 12.

[0028] Please see Figure 1-5 As shown, the guide plate 14 has multiple sets of first-level sliding grooves 2 in the middle; the first-level sliding groove 2 is rotatably connected to a first-level blocking plate 21 by a torsion spring; a second-level sliding groove 22 is provided between each pair of positioning plates 13; a second-level blocking plate 23 is rotatably connected between each pair of second-level sliding grooves 22 by a torsion spring; during operation, as the airflow moves upward, the positioning plate 13, guide plate 14, first-level blocking plate 21, and second-level blocking plate 23 installed on the top of the aeration head 12 can keep the outlet of the aeration head 12 in a cavity state, and under the action of air pressure, the second-level blocking plate 23 is moved upward. The baffle plate 23 and the first baffle plate 21 rotate to allow air to be discharged outwards. After the subsequent sewage sedimentation, the first baffle plate 21 and the second baffle plate 23 are reset under the action of the torsion spring, blocking external sewage impurities. This step utilizes the blocking effect of the second baffle plate 23 and the first baffle plate 21 on the sewage to block the outlet of the aeration head 12 during the subsequent static sedimentation after the sewage reaction, reducing the downward-falling impurities from obliquely bypassing the guide plate 14 and entering the interior of the aeration head 12, maintaining the unobstructed flow inside the aeration head 12 and reducing blockage.

[0029] Please see Figure 1-5As shown, a sliding plate 3 is provided in the middle of the guide plate 14; multiple sets of third slide grooves 31 are provided on the top of the sliding plate 3 at the location of the first slide groove 2; a receiving plate 32 is rotatably connected to the top side wall of the third slide groove 31; the third slide groove 31 is sloped, and a first roller 34 slides inside the third slide groove 31; a first connecting rope 33 is fixed to the side wall of the first roller 34; the end of the first connecting rope 33 passes through the guide plate 14 and contacts the side wall of the first barrier plate 21; during operation, as the air at the bottom of the guide plate 14 continues to rise and pressurize, the first barrier plate 21 will... As the rotation progresses, the movement of the first barrier plate 21 pulls on the first connecting rope 33, causing the first roller 34 to move inside the third chute 31. During this movement, the first roller 34 gradually comes into contact with the receiving plate 32 due to the slope of the third chute 31, causing the receiving plate 32 to rotate and tilt. This step utilizes the rotation effect of the first barrier plate 21 to drive the first roller 34 to move inside the third chute 31, thereby causing the receiving plate 32 to rotate. This causes impurities remaining on the surface to fall off, reducing the accumulation of impurities on the guide plate 14 and preventing them from affecting the normal rotation of the first barrier plate 21.

[0030] Please see Figure 1-5 As shown, multiple sets of blocking blocks 4 are fixed to the side wall of the third slide 31; a fourth slide 41 is opened on the top of the blocking block 4; a second roller 42 is rotatably connected inside the fourth slide 41 located on the side wall of the third slide 31; the blocking block 4 and the second roller 42 are arranged in an arc shape; during operation, as the first blocking plate 21 rotates under air compression, the first roller 34 is pulled, causing it to continuously contact the multiple sets of fourth slides 41, resulting in a jerking effect during the movement of the first roller 34. At the same time, the receiving plate 32 vibrates up and down during its rotation. This step utilizes the multiple sets of blocking blocks 4 installed on the side wall of the third slide 31 to cause the first roller 34 to undulate during its movement, resulting in a jerking effect during the rotation of the receiving plate 32, causing surface impurities to fall and reducing the accumulation of impurities on the slide plate 3.

[0031] Please see Figure 1-5As shown, each of the four corners of the aeration tank 1 is fixedly connected with a sliding rod 5; multiple sets of sliding rods 5 are slidably connected with support rods 51; multiple sets of support plates 52 are fixedly connected to the middle of the support rods 51; and side plates 53 are provided on both sides of the multiple sets of support plates 52. During operation, when the sewage inside the aeration tank 1 is aerated, the sliding rods 5 can restrict the support rods 51 from moving up and down. At this time, impurities in the sewage will come into contact with the side plates 53. Subsequently, air will be discharged from the aeration head 12, causing it to move upward. The upward-moving air cannon will come into contact with the bottom of the side plate 53. Utilizing the bent design of the side plate 53, the air bubbles can move to both sides of the side plate 53, causing impurities to be turned over in the recessed area of ​​the side plate 53. This step, using the movable support rods 51 installed inside the aeration tank 1, can turn the sewage up and down during the purification and sedimentation process, causing some impurities to remain in the recessed area of ​​the side plate 53, thereby reducing the sedimentation of impurities and affecting the air discharge from the aeration head 12.

[0032] Please see Figure 1-5 As shown, each of the multiple sets of side plates 53 has a first rotating shaft 6 fixedly connected to its sidewall; the first rotating shaft 6 is rotatably connected to the sidewall of the support rod 51; multiple sets of second connecting ropes 61 are connected between the sidewall of the support plate 52 and the sidewall of the side plate 53; the support plate 52 has guide grooves 62 on both its upper and lower surfaces; during operation, when the air is discharged from the air supply aeration head 12 and moves upward, the second connecting ropes 61 can use their own curvature to cooperate with the opening of the guide grooves 62 on both sides of the support plate 52 to guide the movement trajectory of the airflow, so that the bubbles move to both sides. At the same time, under the continuous impact of the bubbles, the side plate 53 will rotate around the first rotating shaft 6 as the center, producing a shaking effect. This step uses the rotatable first rotating shaft 6 installed on the sidewall of the side plate 53 to produce a shaking effect during the rising of the bubbles and the movement of the side plate 53, so that the bubbles can smoothly detach from the side plate 53 after contact, reducing the upward tilting of the bottom of the side plate 53 due to the presence of bubbles.

[0033] Please see Figure 1-5 As shown, multiple sets of hooks 7 are fixed to the corresponding side walls of the multiple sets of side plates 53. During operation, when the air bubbles moving upward in the aeration head 12 come into contact with the side plates 53, the curvature of the bottom of the side plates 53 can cause the air bubbles to move to both sides. At this time, the flocculent matter in the sewage will be blocked and collected by the hooks 7. This step uses the multiple sets of hooks 7 installed on the side walls of the side plates 53 to grab the flocculent matter in the sewage, reduce the presence of flocculent floating matter in the water, and reduce the contact between the flocculent matter in the sewage and the aeration head 12.

[0034] Please see Figure 1-5As shown, a rotating rod 8 is rotatably connected to the bottom center of the guide plate 14; multiple sets of fan blades 82 are fixed to the side wall of the rotating rod 8; and collision balls 81 are connected to the ends of the fan blades 82 via ropes. During operation, as the airflow in the aeration head 12 moves upward and comes into contact with the fan blades 82, the impact effect of the airflow causes the fan blades 82 to rotate, causing the collision balls 81 to collide with the side wall of the positioning plate 13 under centrifugal force. This step utilizes the upward impact force generated by the airflow inside the aeration head 12 to drive the fan blades 82 to rotate, and the centrifugal force causes the collision balls 81 to contact the side wall of the multiple sets of positioning plates 13, resulting in collisions and reducing the adhesion of external impurities.

[0035] Please see Figure 1-5 As shown, the side wall of the guide plate 14 is rotatably connected to the second rotating shaft 9 on the side away from the first roller 34; the side wall of the second rotating shaft 9 is in contact with the first connecting rope 33; during operation, as the first blocking plate 21 rotates outward under air pressure, it pulls the first connecting rope 33 to move. At this time, the first connecting rope 33 will move under the rotation of the second rotating shaft 9, and the rotation of the second rotating shaft 9 will disengage it from the contact with the corner of the side wall of the guide plate 14. This step utilizes the rotation effect of the second rotating shaft 9 to disengage the first connecting rope 33 from the contact with the corner of the guide plate 14, and at the same time change the sliding friction to rolling friction, reducing friction.

[0036] Working principle: During the sewage treatment process inside the aeration tank 1, as sewage enters, the guide plate 14 installed on the top of the aeration head 12 can block the water flow, thereby dispersing the water flow to both sides until it submerges the entire aeration head 12. In the subsequent static state of the sewage, the impurities that gradually settle downwards will fall to the top of the guide plate 14. By tilting the top of the guide plate 14 downwards, the amount of impurities entering the interior of the aeration head 12 is reduced. During the upward movement of the airflow, the positioning plate 13, guide plate 14, first barrier plate 21, and second barrier plate 23 installed on the top of the aeration head 12 can keep the outlet of the aeration head 12 in a cavity state. Under the action of air pressure, the second barrier plate 23 and the first barrier plate 21 rotate, allowing air to be discharged outwards. After the sewage settles, the first barrier plate 21 and the second barrier plate 23 are reset under the action of torsion springs, blocking external sewage impurities.

[0037] As the air at the bottom of the guide plate 14 continues to rise and pressurize, the first barrier plate 21 will gradually rotate as the pressure increases. At this time, the movement of the first barrier plate 21 will pull the first connecting rope 33, causing the first roller 34 to move inside the third slide groove 31. During the movement, the first roller 34 will gradually come into contact with the receiving plate 32 due to the slope of the third slide groove 31, causing the receiving plate 32 to rotate at an angle. As the first barrier plate 21 rotates under the air compression, the first roller 34 will be pulled and continuously come into contact with multiple sets of fourth slide grooves 41. This causes the first roller 34 to jerk during movement. At the same time, the receiving plate 32 vibrates up and down during rotation. During the aeration of sewage in the aeration tank 1, the sliding rod 5 can restrict the support rod 51 from moving up and down. At this time, impurities in the sewage will come into contact with the side plate 53. Then, air will be discharged from the aeration head 12, causing it to move upward. The upward-moving air cannon will come into contact with the bottom of the side plate 53. By utilizing the bent design of the side plate 53, the air bubbles can move to both sides of the side plate 53, causing impurities to be turned over in the concave part of the side plate 53.

[0038] As the air bubbles move upward through the air supply aeration head 12, the second connecting rope 61, with its own curvature and the opening of the guide grooves 62 on both sides of the support plate 52, guides the movement trajectory of the airflow, causing the bubbles to move to both sides. Simultaneously, under the continuous impact of the bubbles, the side plate 53 rotates around the first rotating shaft 6, producing a shaking effect. When the upward-moving bubbles in the aeration head 12 come into contact with the side plate 53, the curvature at the bottom of the side plate 53 allows the bubbles to move to both sides. At this time, the flocculent matter present in the wastewater is hooked by the hook 7. During the blocking and collection process, as the airflow in the aeration head 12 moves upward and comes into contact with the fan blade 82, the impact effect of the airflow causes the fan blade 82 to drive the rotating rod 8 to rotate, so that the collision ball 81 contacts and collides with the side wall of the positioning plate 13 under the action of centrifugal force. As the first blocking plate 21 rotates outward under the air pressure, it will pull the first connecting rope 33 to move. At this time, the first connecting rope 33 will move under the rotation of the second rotating shaft 9, and the rotation of the second rotating shaft 9 will disengage from the contact with the side corner of the guide plate 14.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
