Description

Technical Field

[0001] The utility model relates to the technical field of water environmental protection treatment, in particular to an environmental protection water treatment aeration device. Background Technique

[0002] Aeration technology refers to the technology of strengthening air in sewage during sewage treatment in environmental engineering to prevent floating objects in the pool from sinking, and at the same time stirring to promote the rapid movement of oxygen in the air into the sewage, strengthening the contact between microorganisms and organic matter, and finally aiming to decompose and oxidize the organic matter in the sewage. In addition, aeration also aims to prevent the suspension in the pool from sinking and strengthen the contact between the organic matter, microorganisms and dissolved oxygen in the pool, so as to ensure the oxidation and decomposition of the organic matter in the sewage by the microorganisms in the pool under the condition of sufficient dissolved oxygen. Most of the current environmental protection water treatment aeration devices adopt submersible aeration equipment, and aeration pipes are arranged in the water treatment pool. After inhaling external air, the air is ejected through the aeration pipes, so that the gas contacts the water body, increasing the oxygen content in the water body and accelerating the purification of the water body. However, most of the existing water treatment aeration devices are fixedly arranged at the bottom of the water treatment pool, the aeration position is fixed and multiple aeration devices need to be set up to aerate the water area, which occupies a large area at the bottom of the pool and is very troublesome to install. Content of the Utility Model

[0003] The purpose of the utility model is to provide an environmental protection water treatment aeration device to solve the problem that a large number of aeration devices are arranged at the bottom of the pool to carry out large-area aeration as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an environmental protection water treatment aeration device, including an installation cross plate, the installation cross plate is erected and fixed at the upper end of the sewage treatment pool, and an air pump is fixedly installed on the outer surface of the installation cross plate. The outer surface of the installation cross plate is penetrated by a connecting piece, and the connecting piece is attached to the outer surface of the installation cross plate, and the installation cross plate and the connecting piece are fixedly connected. A gas delivery transmission pipe is rotatably installed on the outer surface of the installation cross plate, and the gas delivery transmission pipe is rotatably connected to the connecting piece, and the connecting piece is connected to the output end of the air pump. A rotation meshing mechanism is arranged on the outer surface of the installation cross plate. The gas delivery transmission pipe is driven to rotate by the rotation meshing mechanism to spread and disperse the gas, so that the gas can fully roll and mix with the sewage in the sewage treatment pool.

[0005] Preferably, the rotation meshing mechanism includes: a servo drive motor, which is fixedly installed inside the mounting cross plate, and a second bevel gear is fixedly installed at the output end of the servo drive motor. A first bevel gear is fixedly installed on the outer surface of the air supply transmission pipe, and the first bevel gear meshes with the second bevel gear, and the second bevel gear is located inside the second bevel gear. A sealing ring is fixedly installed on the outer surface of the air supply transmission pipe, and the outer surface of the sealing ring fits with the inner wall of the air supply transmission pipe, and the air supply transmission pipe and the connecting piece are concentrically designed.

[0006] Adopting the above technical solution, it can drive the air supply transmission pipe to rotate. Through the rotation of the air supply transmission pipe, the aeration component can rotate in the sewage tank, enabling the gas to come into contact with the sewage in the sewage tank over a large area and tumbling and stirring the sewage. At the same time, it can prevent air leakage at the connection between the connecting piece and the air supply transmission pipe through the sealing ring.

[0007] Preferably, a separation mechanism is provided at one end of the air supply transmission pipe away from the air pump. Through the separation mechanism, all the air pumped by the air pump is dispersed to expand the contact area with the sewage.

[0008] Adopting the above technical solution, the gas sent by the air supply transmission pipe can be gathered and dispersed through the gas distribution groove.

[0009] Preferably, the separation mechanism includes: a gas distribution groove, which is fixedly installed at one end of the air supply transmission pipe away from the connecting piece, and a delivery pipe is installed through the outer surface of the gas distribution groove. Aeration structures are uniformly installed on the outer surface of the delivery pipe, and through holes are uniformly opened on the outer surface of the aeration structures, and the through holes of the aeration structures face the bottom of the sewage tank.

[0010] Adopting the above technical solution, when the gas is transported through the delivery pipe and discharged outward through the aeration structure, the aeration structure blows up the suspended solids deposited at the bottom of the sewage tank, and the suspended solids are carried above the sewage tank by the gas, so that the gas blown out by the aeration structure stirs the sewage, enabling the sewage to come into contact with the gas more fully, enabling the gas to blend with the sewage more fully, and enabling the gas to enter the delivery pipe evenly through the gas distribution groove.

[0011] Preferably, a rotation mechanism is fixedly installed on the outer surface of the delivery pipe. Through the rotation mechanism, the suspended solids in the sewage tank and at the bottom of the tank can be stirred and circulated in the tank following the ejected bubbles.

[0012] Adopting the above technical solution, it can stir the suspended solids at the bottom of the sewage tank and make the suspended solids rise with the aeration structure, preventing the suspended solids from settling at the bottom of the sewage tank.

[0013] Preferably, the rotation mechanism includes: a rotation fixing groove fixedly installed on the outer surface of the conveying pipe, and the conveying pipe and the rotation fixing groove are eccentrically designed. A pneumatic blade is rotatably installed inside the rotation fixing groove, and a first transmission gear is fixedly installed on the rotating shaft of the pneumatic blade. A stirring blade is rotatably installed on the outer surface of the rotation fixing groove, and a second transmission gear is fixedly installed at one end of the stirring blade. The second transmission gear meshes with the first transmission gear, and the diameter of the first transmission gear is larger than that of the second transmission gear, and the second transmission gear and the first transmission gear are located inside the first transmission gear.

[0014] With the above technical solution, when the gas passes through the conveying pipe, it will blow the pneumatic blade, and drive the first transmission gear to rotate through the rotation of the pneumatic blade, so that the second transmission gear meshing with the first transmission gear rotates, and the second transmission gear drives the stirring blade to stir the suspended matter at the bottom of the sewage tank, and accelerates the rotation of the stirring blade through the diameter difference between the first transmission gear and the second transmission gear, so that the suspended matter deposited at the bottom of the sewage tank is stirred and lifted.

[0015] Preferably, a base is rotatably installed on the outer surface of one end of the air supply transmission pipe, and the base is fixedly installed at the bottom of the sewage tank. A support connection ring is fixedly installed at the end of the conveying pipe away from the air distribution groove, and support rollers are evenly fixedly installed on the outer surface of the support connection ring.

[0016] With the above technical solution, the air supply transmission pipe can be rotated more stably through the base, and the conveying pipe can be fixed through the support connection ring, so that the conveying pipe is kept in the same plane, and the support rollers support the support connection ring, so that the aeration structure does not contact the bottom of the sewage tank.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: this environmental protection water treatment aeration device:

[0018] 1. The rotation of the servo drive motor drives the second helical gear to rotate, so that the first helical gear meshing with the second helical gear rotates, so that the air supply transmission pipe rotates to drive the conveying pipe to rotate together, so that the aeration structure rotates inside the sewage tank, so that the aeration structure can move and discharge air in the sewage tank, so that the air can be fully contacted with the sewage, and sufficient aeration can be carried out without installing too many aeration devices inside the sewage tank;

[0019] 2. When the gas is discharged from the aeration structure through the delivery pipe, the passing gas will drive the pneumatic blades in the aeration structure to rotate, causing the pneumatic blades to drive the first transmission gear to rotate, and then causing the second transmission gear meshing with the first transmission gear to rotate. The diameter difference between the second transmission gear and the first transmission gear drives the stirring blades to rotate at an accelerated speed, enabling the stirring blades to quickly stir the suspended matter deposited at the bottom of the sewage tank, allowing the suspended matter to rise with the gas ejected from the aeration structure. The gas blows the pneumatic blades to drive the stirring blades to rotate, preventing the suspended matter from settling;

[0020] 3. The base enables the air supply transmission pipe to rotate more stably without drifting. The support connection ring can keep the delivery pipe at the same height. At the same time, the support rollers are evenly arranged on the outer surface of the support connection ring, which can support the delivery pipe and the support connection ring during rotation, preventing the support connection ring and the delivery pipe from deforming, and keeping the aeration structure from contacting the bottom of the sewage tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: an environmental protection water treatment aeration device, including a mounting cross plate 1, the mounting cross plate 1 is erected and fixed at the upper end of the sewage treatment tank, and an air pump 2 is fixedly installed on the outer surface of the mounting cross plate 1. The outer surface of the mounting cross plate 1 is penetrated by a connecting piece 3, and the connecting piece 3 is in contact with the outer surface of the mounting cross plate 1, and the mounting cross plate 1 and the connecting piece 3 are fixedly connected. A gas delivery pipe 4 is rotatably installed on the outer surface of the mounting cross plate 1, and the gas delivery pipe 4 is rotatably connected to the connecting piece 3, and the connecting piece 3 is connected to the output end of the air pump 2. A rotational meshing mechanism is arranged on the outer surface of the mounting cross plate 1. The gas delivery pipe 4 is driven to rotate by the rotational meshing mechanism to spread and disperse the gas, so that the gas can fully roll and mix with the sewage in the sewage treatment tank.

[0030] Setting the air pump 2 and the servo drive motor 7 on the mounting cross plate 1 can keep the air pump 2 and the servo drive motor 7 away from the sewage, reducing the probability of failure of the air pump 2 and the servo drive motor 7. At the same time, the sealing ring 5 can ensure the sealing between the connecting piece 3 and the gas delivery pipe 4, so that no gas leaks when the gas delivery pipe 4 rotates. At the same time, it is convenient to repair and maintain the servo drive motor 7, the air pump 2 and the connecting piece 3 through the mounting cross plate 1.

[0031] The rotational meshing mechanism includes: a servo drive motor 7, the servo drive motor 7 is fixedly installed inside the mounting cross plate 1, and a second bevel gear 8 is fixedly installed at the output end of the servo drive motor 7. A first bevel gear 6 is fixedly installed on the outer surface of the gas delivery pipe 4, and the first bevel gear 6 meshes with the second bevel gear 8, and the second bevel gear 8 is located inside the second bevel gear 8. A sealing ring 5 is fixedly installed on the outer surface of the gas delivery pipe 4, and the outer surface of the sealing ring 5 is in contact with the inner wall of the gas delivery pipe 4, and the gas delivery pipe 4 and the connecting piece 3 are concentrically designed.

[0032] The rotation of the servo drive motor 7 will drive the second bevel gear 8 to rotate, causing the first bevel gear 6 meshing with the second bevel gear 8 to rotate. The rotation of the first bevel gear 6 drives the gas delivery pipe 4 to rotate, causing the conveying pipe 10 to rotate together, driving the aeration structure 16 to rotate in the sewage tank. Through the movement of the aeration structure 16, the gas can come into full contact with the sewage in the sewage tank over a large area, without the need to install a large number of aeration components.

[0033] One end of the air supply transmission pipe 4 far from the air pump 2 is provided with a separation mechanism. Through the separation mechanism, all the air pumped by the air pump 2 is dispersed to expand the contact area with the sewage. The separation mechanism includes: an air distribution groove 9. The air distribution groove 9 is fixedly installed at one end of the air supply transmission pipe 4 far from the connecting piece 3, and a delivery pipe 10 is installed through the outer surface of the air distribution groove 9. Aeration structures 16 are evenly installed on the outer surface of the delivery pipe 10, and through holes are evenly formed on the outer surface of the aeration structures 16, and the through holes of the aeration structures 16 face the bottom of the sewage tank.

[0034] When the air pump 2 operates to inject external air into the interior of the air supply transmission pipe 4 through the connecting piece 3, the gas will flow along the air supply transmission pipe 4 into the air distribution groove 9, and enter the delivery pipe 10 separately through the air distribution groove 9, and be discharged from the aeration structures 16 through the transmission of the delivery pipe 10. The gas discharged through the aeration structures 16 takes away the suspended matters in the sewage and rises, and reduces the deposition of suspended matters at the bottom of the sewage tank. At the same time, a large amount of air can be incorporated into the sewage to accelerate the decomposition of organic matters in the sewage by microorganisms, so that the gas can be separately injected into the delivery pipe 10.

[0035] A rotating mechanism is fixedly installed on the outer surface of the delivery pipe 10. Through the rotating mechanism, the suspended matters in the sewage tank and at the bottom of the tank can be agitated and circulated in the tank following the ejected bubbles. The rotating mechanism includes: a rotating fixed groove 11. The rotating fixed groove 11 is fixedly installed on the outer surface of the delivery pipe 10, and the delivery pipe 10 and the rotating fixed groove 11 are eccentrically designed. A pneumatic blade 12 is rotatably installed inside the rotating fixed groove 11, and a first transmission gear 13 is fixedly installed on the rotating shaft of the pneumatic blade 12. A stirring blade 14 is rotatably installed on the outer surface of the rotating fixed groove 11, and a second transmission gear 15 is fixedly installed at one end of the stirring blade 14. The second transmission gear 15 meshes with the first transmission gear 13, and the diameter of the first transmission gear 13 is larger than that of the second transmission gear 15, and the second transmission gear 15 and the first transmission gear 13 are located inside the first transmission gear 13.

[0036] As the gas passes through the delivery pipe 10 and is discharged from the aeration structures 16, the gas passing through the delivery pipe 10 will simultaneously pass through the rotating fixed groove 11. The passing gas will blow the pneumatic blade 12 to drive the first transmission gear 13 to rotate, so that the second transmission gear 15 meshing with the first transmission gear 13 rotates. The diameter difference between the second transmission gear 15 and the first transmission gear 13 drives the stirring blade 14 to rotate at an accelerated speed, increasing the rotation speed of the stirring blade 14, so that the stirring blade 14 stirs up the suspended matters deposited at the bottom of the sewage tank, and cooperates with the gas blown out by the aeration structures 16 to drive the suspended matters to suspend in the sewage, reducing the deposition of suspended matters at the bottom of the sewage tank, and strengthening the contact between the organic matters, microorganisms and dissolved oxygen in the tank.

[0037] A base 19 is rotatably installed on the outer surface of one end of the air supply transmission pipe 4, and the base 19 is fixedly installed at the bottom of the sewage tank. One end of the transmission pipe 10 away from the air distribution groove 9 is fixedly installed with a support connection ring 17, and support rollers 18 are evenly fixedly installed on the outer surface of the support connection ring 17.

[0038] The base 19 enables the air supply transmission pipe 4 to operate more stably without eccentricity during rotation. At the same time, the support connection ring 17 can keep the transmission pipe 10 at the same height. With the use of the support rollers 18, the support connection ring 17 and the transmission pipe 10 can be supported without deformation and rotate more stably. At the same time, the distance between the aeration structure 16 and the stirring blades 14 and the bottom of the sewage tank can be maintained, reducing the probability of damage caused by contact and scraping between the stirring blades 14 and the aeration structure 16 and the bottom of the sewage tank during rotation.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
