Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an aeration device for a carbonization tank in wastewater treatment. Background Technology

[0002] In the carbonization tank process of wastewater treatment, aeration is the core step in promoting the metabolic degradation of pollutants by microorganisms by oxygenating the wastewater. Its uniformity directly determines the treatment efficiency and effluent quality. Currently, most mainstream aeration devices adopt a blower aeration system, in which a blower delivers air through pipelines to the aeration pipes at the bottom of the tank, and oxygenation is achieved by dispersing air bubbles through aeration heads.

[0003] However, existing devices generally suffer from uneven aeration: due to factors such as fixed bubble rising paths and insufficient water circulation, the area near the aeration pipe has dense bubbles, ensuring sufficient contact between wastewater and air and adequate dissolved oxygen; while the distant area has anoxic zones due to bubble loss and obstructed diffusion. This difference leads to an imbalance in the activity of the microbial community, significant differences in the degradation rate of pollutants, and reduced overall treatment efficiency. Therefore, we need to propose an aeration device for carbonization tanks in wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for carbonization tanks in wastewater treatment, in order to solve the problem mentioned in the background art that the area close to the aeration pipe has dense bubbles, the wastewater is in full contact with the air, and the dissolved oxygen is sufficient; while the distant area has an oxygen-deficient zone due to bubble loss and obstructed diffusion, resulting in uneven aeration and reduced overall treatment efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A wastewater treatment carbonization tank aeration device includes: an aeration tank with a support plate mounted on its top; an aeration conveying mechanism for air transport mounted on the support plate and extending into the interior of the aeration tank; and a drive mechanism mounted on the support plate, on which a dispersion mechanism for diffused air bubbles transported by the aeration conveying mechanism is mounted, the aeration conveying mechanism being located inside the dispersion mechanism.

[0007] Preferably, the dispersing mechanism includes a connecting frame, a first dispersing blade, and a second dispersing blade; The top of the connecting frame is fixedly installed at the bottom of the connecting ring. Multiple sets of the first and second dispersing blades are provided.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: A wastewater treatment carbonization tank aeration device includes: an aeration tank 1 with a support plate 2 mounted on its top; an aeration conveying mechanism 5 for air conveying, which is mounted on the support plate 2 and extends into the interior of the aeration tank 1; and a drive mechanism 3, mounted on the support plate 2, with a dispersion mechanism 4 mounted on the drive mechanism 3 for the diffusion of air bubbles conveyed by the aeration conveying mechanism 5, the aeration conveying mechanism 5 being located inside the dispersion mechanism 4.

[0018] It should be noted that the support plate 2 is made of 304 stainless steel, which has the characteristics of being resistant to sewage corrosion (resistant to chloride ion and sulfide corrosion) and having high strength (bearing weight ≥500kg), thus avoiding structural deformation caused by long-term immersion.

[0019] In an optional embodiment: such as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the drive mechanism 3 includes a drive motor 31, a drive gear 32, an annular guide rail 33, a connecting ring 34, a slider 35, and an annular gear ring 36; The drive motor 31 is fixedly installed on the top of the support plate 2, the drive gear 32 is fixedly installed on the output shaft of the drive motor 31, the annular guide rail 33 is fixedly installed on the bottom of the support plate 2, multiple sets of sliders 35 are provided, the multiple sets of sliders 35 are evenly fixedly installed on the top of the connecting ring 34, the multiple sets of sliders 35 are all slidably installed on the annular guide rail 33, the annular gear ring 36 is fixedly connected to the side of the connecting ring 34, and the drive gear 32 meshes with the annular gear ring 36.

[0020] It should be noted that the drive motor 31, drive gear 32, annular guide rail 33, connecting ring 34, slider 35 and annular gear ring 36 work together to drive the connecting frame 41 to rotate, providing stable rotational power for bubble dispersion. When the connecting frame 41 rotates, the first dispersion blade 42 and the second dispersion blade 43 diffuse the air bubbles delivered by the aeration conveying mechanism 5 into the interior of the aeration tank 1 for aeration, eliminating the difference between dense near the pipe and oxygen deficiency at the far end, achieving uniform distribution of dissolved oxygen throughout the tank. The uniform aeration environment can balance the activity of the microbial community, avoid local degradation rate differences, and greatly improve the overall degradation efficiency of pollutants.

[0021] In an optional embodiment: such as Figures 2 to 4 As shown, the dispersing mechanism 4 includes a connecting frame 41, a first dispersing blade 42, and a second dispersing blade 43; The top of the connecting frame 41 is fixedly installed at the bottom of the connecting ring 34. Multiple sets of the first dispersing blades 42 and the second dispersing blades 43 are provided. Multiple sets of the first dispersing blades 42 are evenly distributed and fixedly connected to the connecting frame 41, and multiple sets of the first dispersing blades 42 are inclined. Multiple sets of the second dispersing blades 43 are evenly distributed and fixedly connected to the side near the bottom of the connecting frame 41, and the second dispersing blades 43 are inclined.

[0022] It should be noted that the connecting frame 41 has a hollow design and is made of welded stainless steel tubes; The connecting frame 41, the first dispersing blade 42 and the second dispersing blade 43 work together to shear the large agglomerated bubbles (diameter ≥ 5 mm) released from the aeration pipe 52 and break them into micro bubbles (diameter 1-3 mm), increasing the contact area between the bubbles and the sewage. The rotating blades drive the sewage to form a "ring vortex", which diffuses the micro bubbles from around the aeration pipe 52 to the far end of the aeration tank 1, eliminating the difference of "high DO near the pipe and low DO at the far end". The first dispersing blade 42 is set at an angle. When the blade rotates, it will generate an outward radial thrust on the surrounding water, pushing the water flow and air bubbles toward the edge of the aeration tank 1. At the same time, when the second dispersing blade 43 can stir the sewage inside the aeration tank 1, it can prevent suspended objects in the aeration tank 1 from sinking, strengthen the contact between organic matter, microorganisms and dissolved oxygen in the aeration tank 1, oxidize and decompose the organic matter in the sewage, and enhance the aeration efficiency and effect.

[0023] In an optional embodiment: such as Figures 2 to 5 As shown, the aeration conveying mechanism 5 includes a conveying pipe 51, an aeration pipe 52, an aeration disc 53, and an aeration hole 54. The conveying pipe 51 is fixedly connected inside the support plate 2, and the lower end of the conveying pipe 51 extends to the bottom of the support plate 2. The top of the aeration pipe 52 is fixedly connected to the bottom of the conveying pipe 51, and the top of the aeration disc 53 is fixedly connected to the bottom of the aeration pipe 52. The aeration pipe 52 is connected to the conveying pipe 51 and the aeration disc 53. Multiple sets of aeration holes 54 are opened on both the aeration pipe 52 and the aeration disc 53.

[0024] It should be noted that the conveying pipe 51, aeration pipe 52, aeration disc 53 and aeration hole 54 are connected to reach deep into the aeration tank 1 and perform aeration. This facilitates the diffusion of air bubbles inside the aeration tank 1 when the driving mechanism 3 and the dispersing mechanism 4 diffuse the air bubbles.

[0025] In an optional embodiment: such as Figure 4 As shown, the connecting frame 41 is sleeved on the outside of the aeration pipe 52, and the aeration disc 53 is located below the connecting frame 41.

[0026] It should be noted that, by means of the connecting frame 41 being fitted on the outside of the aeration pipe 52, when air bubbles are discharged through the aeration pipe 52 and the aeration disc 53, the air bubbles can be dispersed by the connecting frame 41, the first dispersing blade 42 and the second dispersing blade 43, so that the air bubbles diffuse inside the aeration tank 1. The air bubbles discharged through the aeration disc 53 can be dispersed when the second dispersing blade 43 rotates, so that the air bubbles can diffuse inside the aeration tank 1.

[0027] In an optional embodiment: such as Figures 2 to 4 As shown, the sides of multiple sets of first dispersing blades 42 all extend to the inner side of the connecting frame 41.

[0028] It should be noted that the side of the first dispersing blade 42 is close to the side of the aeration pipe 52, and only 5 mm away from the pipe wall of the aeration pipe 52. When air bubbles are discharged through the aeration pipe 52 and the aeration disc 53, the first dispersing blade 42 is rotated by the connecting frame 41, which ensures that the blade can effectively contact and shear the bubbles, while avoiding mechanical friction and collision between the blade and the pipe.

[0029] In an optional embodiment: such as Figure 1 and Figure 2As shown, it also includes a blower 9, which is fixedly installed on the top of the support plate 2, and the delivery pipe 51 is connected to the air outlet of the blower 9.

[0030] It should be noted that, through the setting of blower 9, outside air can be drawn in and transported through conveying pipe 51 to aeration pipe 52 and aeration disc 53, and then discharged through aeration holes 54 on aeration pipe 52 and aeration disc 53.

[0031] In an optional embodiment: such as Figure 1 and Figure 2 As shown, a storage seat 6 is fixedly connected to both sides of the support plate 2. A threaded rod 7 is installed in the internal thread of the storage seat 6. A clamping block 8 is movably installed at the end of the threaded rod 7. The clamping block 8 abuts against the side of the aeration tank 1.

[0032] It should be noted that the threaded rod 7 and the clamping block 8 cooperate to fix the support plate 2. There is no need to drill or weld on the aeration tank 1. The support plate 2 can be installed on the top of the aeration tank 1, which facilitates the installation and disassembly of the support plate 2. It can be installed and disassembled when the drive mechanism 3, the dispersion mechanism 4 and the aeration conveying mechanism 5 need to be maintained. The storage seat 6 serves to store the clamping block 8, preventing the clamping block 8 from contacting the aeration tank 1 and affecting the installation of the support plate 2 during the installation process.

[0033] The usage process of this utility model is as follows: start the blower 9, the blower 9 draws air and then transports it through the conveying pipe 51 to the aeration pipe 52 and aeration disc 53, and the air bubbles are transported out through the aeration holes 54 on the aeration pipe 52 and aeration disc 53. When the drive motor 31 is started, the output shaft of the drive motor 31 drives the drive gear 32 to rotate. When the drive gear 32 rotates, the transmission ring gear ring 36 drives the connecting ring 34 to rotate. The connecting ring 34 drives the connecting frame 41 to rotate. When the connecting frame 41 rotates, it drives the first dispersing blade 42 and the second dispersing blade 43 to rotate. This causes the air bubbles output by the aeration conveying mechanism 5 to be strongly sheared and evenly diffused in the pool, eliminating the difference between dense near the pipe and oxygen deficiency at the far end. This achieves a uniform distribution of dissolved oxygen throughout the pool. The uniform aeration environment can balance the activity of the microbial community, avoid local degradation rate differences, greatly improve the overall degradation efficiency of pollutants, and ensure that the effluent water quality meets the standards.

[0034] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application. The device is powered by an external power supply.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
