DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] A sewage aeration treatment tank and a treatment process thereof according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0041] See also Figure 1-Figure 11 According to an embodiment of the present application, a sewage aeration treatment tank includes: a treatment tank storage mechanism 1, a rotation drive connecting mechanism 2 and an aeration mechanism 3.

[0042] Among them, the pre-treated sewage is discharged into the treatment box storage mechanism 1 through the pipeline. Through the cooperation of the rotation driving connecting mechanism 2 and the aeration mechanism 3, the sewage inside the treatment box storage mechanism 1 is quickly aerated, and the microbubbles can be more quickly and comprehensively mixed with the sewage inside the treatment box storage mechanism 1, thereby improving the aeration efficiency of sewage treatment. The aeration mechanism 3 has a good anti-clogging effect, and in daily use, it can effectively reduce the situation where the air holes are blocked.

[0043] See also Figure 1 , Figure 3-Figure 9The treatment box storage mechanism 1 includes a sewage storage box 11, and the outer side of the sewage storage box 11 is respectively provided with a connected drainage pipe 13 and a sewage pipe 42. The rotation drive connecting mechanism 2 includes a beam frame 21, a motor 22, a pipe fitting 23 and an outer shell 24. The beam frame 21 is fixedly arranged above the sewage storage box 11 by bolts, and the motor 22 is installed on the beam frame 21. The top of the pipe fitting 23 is connected to the output shaft end of the motor 22 through a coupling, and the outer shell 24 is movably sleeved on the outside of the pipe fitting 23, and the outer shell 24 is connected to the beam frame 21 through a hanging rod 25. An air inlet 27 is provided on the outer wall of the pipe fitting 23 located inside the outer shell 24, an air inlet pipe 26 is connected to one side of the outer shell 24, and an air outlet 28 is provided on the side wall of the lower section of the pipe fitting 23. The aeration mechanism 3 includes a sleeve 31, a blade 32, a ball shell 33 and an elastic diaphragm 34. The sleeve 31 is fixedly sleeved on the outside of the pipe 23 by bolts, and the outer wall of the sleeve 31 is provided with a vent 35 connected to the air outlet 28. A cavity 36 is provided in the middle of the blade 32, and the two ends of the blade 32 are respectively connected to the sleeve 31 and the ball shell 33, and the blade 32 is tilted on the outside of the sleeve 31. The top and bottom of the ball shell 33 are respectively cut, and two elastic diaphragms 34 are respectively arranged at the cuts at the top and bottom of the ball shell 33, and the surface of the elastic diaphragm 34 is provided with multiple groups of micropores.

[0044] The pre-treated sewage is discharged into the sewage storage tank 11 through a pipeline. The gas adding device pressurizes the gas and adds it through the air inlet pipe 26. The gas inside the air inlet pipe 26 enters the outer shell 24. The gas in the outer shell 24 enters the pipe 23 through the air inlet 27 on the outside of the top of the pipe 23. The gas in the pipe 23 then enters the cavity 36 in the blade 32 through the air outlet 28 in the lower section and the air vent 35 on the outside of the sleeve 31, and enters the spherical shell 33 through the cavity 36. Finally, it is discharged from the micropores on the top and bottom elastic diaphragms 34 of the spherical shell 33. The discharged bubbles contact with the impurities in the sewage, so that the impurity particles float to the liquid surface. The floating impurities are finally discharged from the sewage pipe 42, so that the granular impurities inside the sewage storage tank 11 are cleaned and discharged. During aeration, after the inside of the spherical shell 33 is filled with gas, the micropores on the surface of the elastic diaphragm 34 expand, and the gas can be discharged smoothly to form microbubbles. When the aeration mechanism 3 stops being used, the micropores on the surface of the elastic diaphragm 34 are in a contracted state and will not be blocked by granular impurities, thus playing a good anti-blocking role.

[0045] During aeration or before aeration, the motor 22 drives the pipe 23 to rotate, and the rotating pipe 23 drives the blade 32 and the spherical shell 33 to rotate simultaneously. Under the stirring action of the inclined blade 32 and the spherical shell 33, the microbubbles discharged from the micropores of the elastic diaphragm 34 and the elastic diaphragm 34 at the top and bottom of the spherical shell 33 can be quickly dispersed and mixed in the sewage inside the sewage storage tank 11, so that the particles in the sewage inside the sewage storage tank 11 quickly contact with the microbubbles, and the impurities attached to the microbubbles quickly float to the liquid surface, thereby improving the cleaning efficiency of impurities in the sewage.

[0046] The sewage aeration treatment box adopts a dynamically rotating spherical shell 33, which cooperates with the micropores on the top and bottom elastic diaphragms 34 to replace the traditional fixed aeration disk. It can not only realize that the discharged microbubbles quickly fill the entire tank, but the micropores arranged on the surface of the elastic diaphragm 34 also have a good anti-blocking effect, ensuring that the aeration mechanism 3 can stably output microbubbles for a long time.

[0047] The elastic diaphragm 34 can be made of rubber or latex material, which has good elasticity. The tiny bubble holes arranged on the surface of the diaphragm can form tiny bubbles in the sewage through which air can pass.

[0048] After the elastic diaphragm 34 at the top and bottom of the spherical shell 33 in the above-mentioned sewage aeration treatment box stops operating for a long time inside the sewage storage tank 11, a layer of impurities and sludge is easily attached to the surface of the elastic diaphragm 34, causing the surface of the elastic diaphragm 34 to be covered with sludge, thereby affecting the microporous exhaust of the entire surface of the elastic diaphragm 34.

[0049] See also Fig. 9 The sewage aeration treatment tank also includes a dirt layer scraping mechanism 5. Two groups of dirt layer scraping mechanisms 5 are respectively arranged above and below the spherical shell 33 to scrape the dirt layer on the surface of the elastic diaphragm 34. The dirt layer scraping mechanism 5 includes a pillar 51, a scraper 52 and a conical cover 55. One end of the pillar 51 is fixedly connected to the blade 32. The two ends of the scraper 52 are respectively connected to a first connecting rod 53 and a second connecting rod 54. The other end of the first connecting rod 53 is rotatably arranged with the pillar 51, and the conical cover 55 is arranged at the other end of the second connecting rod 54. A limit rod 57 is arranged outside the spherical shell 33.

[0050] During the aeration operation, the motor 22 drives the lower pipe 23 to rotate in advance, and the rotating pipe 23 drives the external blade 32 and the ball shell 33 to rotate counterclockwise synchronously. When the rotating ball shell 33 moves, the dirt layer scraping mechanism 5 also rotates counterclockwise with the blade 32 and the ball shell 33. Since the ball shell 33 and the dirt layer scraping mechanism 5 are both inclined, when the aeration mechanism 3 is in a static state, the scraper 52 in the dirt layer scraping mechanism 5 is located at the front side of the ball shell 33 and is limited by the limit rod 57 at the front side of the ball shell 33. When the aeration mechanism 3 and the dirt layer scraping mechanism 5 rotate counterclockwise, the larger opening of the conical cover 55 in the rotating dirt layer scraping mechanism 5 moves relative to the sewage. Under the resistance of the sewage, the conical cover 55 drives the scraper 52 and the first connecting rod 53 to rotate around the support 51 through the second connecting rod 54. The scraper 52 rotates at a certain angle to quickly clean the sludge layer attached to the surface of the elastic diaphragm 34 until the limiting rod 57 on the rear side of the spherical shell 33 limits the scraper 52.

[0051] With the cooperation of the dirt layer scraping mechanism 5 and the rotating drive connecting mechanism 2 and the aeration mechanism 3, the motor 22 is started in advance before aeration, so that the sludge layer on the surface of the spherical shell 33 can be cleaned before the aeration operation, ensuring that the aeration mechanism 3 can stably and high-quality output microbubbles to mix the impurity particles in the sewage inside the sewage storage tank 11, so that the aeration treatment tank can always be in a good state to aerate the particulate impurities in the sewage.

[0052] When the aeration treatment is completed, the motor 22 stops driving the blades 32 and the ball shell 33 to rotate. Since the ball shell 33 and the dirt layer scraping mechanism 5 are both inclined, under the action of gravity, the conical cover 55 will drive the scraper 52 and the first connecting rod 53 to rotate around the support 51 through the second connecting rod 54 and reset to the front side of the elastic diaphragm 34. The limiting rod 57 on the front side of the ball shell 33 limits the scraper 52. The reset conical cover 55 can automatically clean the surface of the elastic diaphragm 34 again when the motor 22 is started next time.

[0053] In the specific configuration, a fixing rod 56 is provided between the two conical covers 55 for fixing and supporting. The fixing rod 56 and the conical covers 55 are fixed by welding to enhance the stability of the two conical covers 55 when rotating. The rear surface of the scraper 52 is inclined, and the inclined scraper 52 can move under a smaller force to clean the dirt layer attached to the surface of the elastic diaphragm 34.

[0054] For further information, see Figure 5The pipe fitting 23 includes a ventilation riser 231 and a lower rod 232. The lower rod 232 is screwed and installed at the lower section of the ventilation riser 231. The air inlet 27 and the air outlet 28 are both arranged outside the ventilation riser 231. A sealing member is arranged between the two ends of the outer shell 24 and the outer wall of the hanging rod 25. The sealing member can be a common rubber sealing ring or a mechanical sealing structure.

[0055] For details, please refer to Figure 1 and Figure 2 The treatment tank storage mechanism 1 also includes a first pump body 12, and the water inlet port of the first pump body 12 is connected to the drain pipe 13. The sewage aeration treatment tank also includes a sewage discharge mechanism 4, which includes a collection box 41, a second pump body 43 and a connecting pipe 44, one end of the connecting pipe 44 is connected to the collection box 41, and the other end of the connecting pipe 44 is connected to the liquid inlet port of the second pump body 43. The waste water floating inside the sewage storage tank 11 can be discharged into the collection box 41 through the sewage discharge pipe 42 for collection, and then the sewage retained in the collection box 41 is discharged through the cooperation of the second pump body 43 and the connecting pipe 44.

[0056] After the scraper 52 cleans the sludge layer remaining on the surface of the elastic diaphragm 34, there is still a large impact between the rotating conical cover 55 and the sewage, so that the scraper 52 is always subjected to a large torque, which can easily lead to fatigue, bending or damage of the scraper 52 in the long term.

[0057] See also Fig. 9 , Fig.10 and Fig.11 The sewage aeration treatment tank also includes a flow guide regulating assembly 6, which includes a tail pipe 61, a flow guide pipe shell 62, a flow guide plate 63 and a reed 64. A port is provided at the tail end of the conical cover 55, and the tail pipe 61 is connected and arranged at the tail end of the conical cover 55, and the tail pipe 61 and the conical cover 55 are connected by welding. The flow guide pipe shell 62 and the tail pipe 61 are screwed and detachably installed, and multiple groups of flow guide plates 63 are arranged in a ring array inside the flow guide pipe shell 62, and the multiple groups of flow guide plates 63 constitute a conical shell structure. The back of the flow guide plate 63 is connected to the inner wall of the flow guide pipe shell 62 through the reed 64.

[0058] When the motor 22 drives the pipe 23 to rotate, the rotating pipe 23 will drive the outer sleeve 31 to rotate, that is, drive the blade 32 and the ball shell 33 outside the sleeve 31 to rotate synchronously. When the motor 22 drives the blade 32 and the ball shell 33 to rotate counterclockwise at the initial start, the rotating blade 32 and the ball shell 33 will drive the conical cover 55 in the dirt layer scraping mechanism 5 to rotate together, and the rotating conical cover 55 will impact the sewage inside the sewage storage tank 11 at the larger opening. The resistance of the conical cover 55 in the sewage will drive the scraper 52 to move backward to scrape off the sludge layer attached to the surface of the elastic diaphragm 34, so as to clean the sludge layer on the surface of the elastic diaphragm 34 and ensure that the micropores on the elastic diaphragm 34 can stably discharge microbubbles. When the rotating conical cover 55 continuously impacts the sewage, the multiple groups of guide plates 63 forming a conical structure inside the guide tube shell 62 will compress the reeds 64 at the back under the impact of the water flow, so that the tail ends of the multiple groups of guide plates 63 present a large crack, and part of the water flow inside the conical cover 55 can be discharged through the crack caused by the impact of the tail ends of the guide plates 63. When the subsequent dirt layer scraping mechanism 5 continues to rotate, it can effectively reduce the impact of sewage on the conical cover 55, that is, reduce the torsion of the scraper 52, and have a certain protective effect on the scraper 52, effectively reducing the scraper 52 from bending and being damaged due to the continuous impact of the conical cover 55 by sewage.

[0059] The design of the above-mentioned flow guide adjustment component 6 is that after the motor 22 stops running, the dirt layer scraping mechanism 5 no longer rotates, and the sewage inside the conical cover 55 no longer passes through the guide tube shell 62. Under the elastic force of the reed 64, the multiple groups of guide plates 63 are reset to a conical structure again. This structural design can block the water inside the conical cover 55 from passing through the guide tube shell 62 when the dirt layer scraping mechanism 5 initially rotates, so that the scraper 52 can be quickly driven to rotate and scrape off the sludge layer attached to the surface of the elastic diaphragm 34. After the sludge layer attached to the surface of the elastic diaphragm 34 is cleaned, when the conical cover 55 rotates, under the continuous impact of the sewage, the multiple groups of guide plates 63 are continuously impacted to compress the reed 64 on the back to cause cracks, so that part of the sewage inside the conical cover 55 flows out through the guide tube shell 62, that is, the impact of the sewage on the conical cover 55 is effectively reduced, and the torque of the scraper 52 is reduced, which has a good protective effect on the scraper 52.

[0060] The present application also provides a treatment process for a sewage aeration treatment tank, comprising the following steps:

[0061] S1: Sewage is added, and the sewage is discharged into the sewage storage tank 11 through a pipe;

[0062] S2: aeration treatment, the gas adding equipment pressurizes the gas and adds it through the air inlet pipe 26, the gas inside the air inlet pipe 26 enters the outer shell 24, the gas in the outer shell 24 enters the pipe 23 through the air inlet 27 on the outside of the top of the pipe 23, the gas in the pipe 23 enters the cavity 36 in the blade 32 through the air outlet 28 in the lower section and the air vent 35 on the outside of the sleeve 31, enters the interior of the spherical shell 33 through the cavity 36, and finally discharges from the micropores on the top and bottom elastic diaphragm 34 of the spherical shell 33, the discharged bubbles come into contact with impurities in the sewage, so that the impurity particles float to the liquid surface, and the floating impurities are finally discharged from the sewage pipe 42;

[0063] S3: Rotate and mix the microbubbles. During aeration, the motor 22 drives the pipe 23 to rotate. The rotating pipe 23 drives the blades 32 and the spherical shell 33 to rotate at the same time. The microbubbles are quickly dispersed and mixed inside the sewage storage tank 11, causing the particulate impurities in the sewage inside the sewage storage tank 11 to quickly float to the liquid surface and be cleaned.

[0064] The treatment process of the sewage aeration treatment box can replace the traditional aeration disk during aeration through the design structure of the rotating driving connecting mechanism 2 and the aeration mechanism 3. While rotating the aeration, the aerated microbubbles can also be quickly mixed into the sewage, thereby improving the sewage aeration mixing efficiency and having a better treatment effect on sewage treatment.

[0065] It should be noted that the specific model specifications of the first pump body 12, the motor 22, and the second pump body 43 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The power supply and principle of the first pump body 12, the motor 22, and the second pump body 43 are clear to those skilled in the art and will not be described in detail here.
