Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more particularly to a sewage treatment disc aerator with a uniformly distributed anti-blocking structure. Background Art

[0002] Aerators are essential equipment for aerating and oxygenating water supply and drainage. Aeration is a means of bringing air and water into strong contact. The purpose is to dissolve oxygen in the air into water, or to expel unnecessary gases and volatile substances in water into the air. In other words, it is a means of promoting material exchange between gas and liquid. Oxygen in the air is transferred to water through aeration, and oxygen is transferred from the gas phase to the liquid phase.

[0003] For example, utility model patent CN217377477U discloses an anti-clogging aerator for water treatment, in which the gas transmitted from the aerator pushes the inclined guide blades, thereby driving the guide blades, rotating blocks, and rotating rods to rotate, preventing impurities in the sewage from entering through the filter holes opened on the fixed plate. At the same time, the top of the rotating guide blade contacts the bottom of the fixed plate, scraping off impurities attached to the bottom of the fixed plate to prevent clogging of the filter holes. However, the above patent document only has the function of directly pushing the fan blades to scrape the top through airflow, and in actual use, there is no setting that can use airflow pressure to impact and clear the blockage of the diaphragm on the top of the aerator, which leads to the diaphragm on the top of the aerator being blocked by debris after long-term use, affecting the use of the aerator. At the same time, there is also a lack of a structure that can disrupt and disperse the airflow discharged from the top of the aerator, so that the airflow discharged from the top of the aerator can only act vertically upward and cannot be dispersed to improve the treatment effect.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: In view of the fact that the existing technology does not have a function of using airflow pressure to impact and clear the blockage of the top diaphragm of the aerator, which leads to the blockage of debris on the top diaphragm of the aerator after long-term use, thus affecting the use of the aerator, the following technical solution is proposed to solve this problem: Refer to the instruction manual Figure 1-Figure 7, a sewage treatment disc aerator with a uniformly distributed anti-blocking structure, such as Figure 1 and Figure 2 As shown, it includes a disc aerator 1, a diaphragm 2 is provided on the top of the disc aerator 1, and an air pushing and cleaning mechanism 3 and a scraping mechanism 4 are provided on the outer wall of the disc aerator 1; like Figure 3 and Figure 4 As shown, the air pushing and cleaning mechanism 3 includes an air guide pipe 31 connected to the outer wall of the disc aerator 1. The air guide pipe 31 is U-shaped. The top of the air guide pipe 31 is connected to the air box 32. The air box 32 is located at the top center of the disc aerator 1. When the disc aerator 1 is started, part of the air flow delivered is guided out through the air guide pipe 31, and then the air flow enters the air box 32 through the air guide pipe 31. Support brackets 33 are fixedly installed on both sides of the air box 32, and the support brackets 33 are fixedly installed on the top of the disc aerator 1. An impeller 34 is provided in the air box 32, and the impeller 34 is arranged in a vertical state. The impeller 34 and one side of the air guide pipe 31 are staggered with each other, and the air flow entering the air box 32 blows towards and drives the impeller 34 to rotate.

[0025] like Figure 3 and Figure 4 As shown, an exhaust hole slot 35 is provided on the top of the air box 32, and the top of the exhaust hole slot 35 is connected to a rotating air pipe 36, which is set in an inverted U shape. A joint 37 is rotatably installed on the other side of the rotating air pipe 36, and the joint 37 is rotatably installed on the top of the air box 32. The bottom of the joint 37 is connected to an air connecting pipe 38, which is set in a vertical state. The outer wall of the connecting pipe 38 and the impeller 34 are fixed to each other. The connecting pipe 38 passes through the bottom of the air box 32. Since the airflow entering can only be discharged through the exhaust hole slot 35, the airflow enters the joint 37 and the connecting pipe 38 through the rotating air pipe 36. At this time, the rotation of the impeller 34 drives the connecting pipe 38 to rotate synchronously.

[0026] like Figure 3 and Figure 4 As shown, the bottom of the air connecting pipe 38 is connected to the exhaust pipe 39, and the exhaust pipe 39 is arranged in a horizontal state. The bottom of the exhaust pipe 39 is connected to a plurality of nozzles 310, and the plurality of nozzles 310 are arranged vertically downward. Then, the rotation of the air connecting pipe 38 drives the exhaust pipe 39 and the plurality of nozzles 310 to rotate synchronously on the top of the diaphragm 2, and the air flow is ejected from the bottom of the exhaust pipe 39 and the plurality of nozzles 310 and blown toward the diaphragm 2, thereby cleaning the debris blocking the diaphragm 2 to avoid blockage.

[0027] like Figure 4 and Figure 5As shown, the scraping mechanism 4 includes a slide rail groove 41 fixedly installed on the outer wall of one side of the exhaust pipe 39, the slide rail groove 41 is set in a horizontal state, and a scraper 42 is slidably installed on one side of the slide rail groove 41, the scraper 42 is set in a vertical state, and the bottom of the scraper 42 is in contact with the top of the diaphragm 2. The rotation of the exhaust pipe 39 drives the slide rail groove 41 and the scraper 42 to rotate synchronously.

[0028] like Figure 4 and Figure 5 As shown, a support spring 43 is fixedly mounted on one side of the scraper 42 , and the support spring 43 is fixedly mounted on the outer wall of the air connection pipe 38 .

[0029] like Figure 4 and Figure 5 As shown, one side of the scraper 42 is provided with a plurality of top protrusions 44, and the plurality of top protrusions 44 are fixedly mounted on the top of the disc aerator 1. The plurality of top protrusions 44 are arranged equidistantly in a circle on the top of the disc aerator 1. When the scraper 42 rotates, one side of the scraper 42 contacts the plurality of top protrusions 44 in sequence, and the scraper 42 is repeatedly pushed by the plurality of top protrusions 44. The pushing scraper 42 is repeatedly moved left and right under the support of the support spring 43 on one side of the scraper 42, thereby driving the pushing scraper 42 to scrape off the debris on the top of the diaphragm 2.

[0030] During specific implementation, part of the air flow delivered by the disc aerator 1 when it is started is led out through the air guide pipe 31, and then the air flow enters the air box 32 through the air guide pipe 31. Since the air flow can only be discharged through the exhaust hole slot 35, the air flow enters the joint 37 and the connecting pipe 38 through the air transfer pipe 36. At this time, the air flow entering the air box 32 blows towards and drives the impeller 34 and the connecting pipe 38 to rotate synchronously. The rotation of the connecting pipe 38 drives the exhaust pipe 39 and the multiple nozzles 310 to rotate synchronously at the top of the diaphragm 2, and the air flow is ejected from the bottom of the exhaust pipe 39 and the multiple nozzles 310 and blows towards the diaphragm 2, thereby cleaning the debris blocking the diaphragm 2 to avoid blockage. At the same time, when the scraper 42 rotates, one side of the scraper 42 contacts multiple top protrusions 44 in sequence, and the scraper 42 is repeatedly pushed by the multiple top protrusions 44. Under the support of the support spring 43 on one side of the scraper 42, the pushing scraper 42 repeatedly moves left and right, thereby driving the pushing scraper 42 to scrape off the debris on the top of the diaphragm 2.

[0031] Example 2: In view of the fact that the prior art still lacks a structure that can disrupt and disperse the airflow discharged from the top of the aerator, and thus the airflow discharged from the top of the aerator can only act vertically upward and cannot be dispersed to improve the treatment effect, in order to solve this problem, the following technical solution is proposed: like Figure 6 and Figure 7As shown, a push plate mechanism 5 is provided on the top of the two support brackets 33 , and the push plate mechanism 5 includes slots 51 opened on the top of the two support brackets 33 . The two slots 51 are symmetrically arranged with each other, and a rotating rod 52 is fixedly installed on the inner wall of the two slots 51 .

[0032] like Figure 6 and Figure 7 As shown, push plates 53 are rotatably installed on the outer walls of the two rotating rods 52. The two push plates 53 are arranged in a vertical state. A vertical plate 54 is fixedly installed on the top of the push plates 53. During the rotation of the exhaust pipe 39, the exhaust pipe 39 approaches and squeezes the push plates 53, and then the push plates 53 are compressed and drive the vertical plates 54 to deflect in the slots 51 through the rotating rods 52. The vertical plates 54 are arranged vertically upward, so that the vertical plates 54 swing to push and disperse the airflow discharged from the top of the disc aerator 1.

[0033] During specific implementation, during the rotation of the exhaust pipe 39, the exhaust pipe 39 approaches and squeezes the push plate 53, and then the push plate 53 is compressed and drives the vertical plate 54 to deflect in the slot 51 through the rotating rod 52, so that the vertical plate 54 swings to push and disperse the airflow discharged from the top of the disc aerator 1.
