DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0017] Example 1 A blocking-proof aeration device, such as Figure 1-Figure 5 As shown, it includes an aeration pipe 1, an air inlet pipe 2 and an aeration net 3; the aeration pipe 1 is connected to the air inlet pipe 2 for conveying air into the interior thereof; the aeration pipe 1 is slidably connected to the aeration net 3 for aerating sewage; The aeration pipe 1 is fixedly connected to the frustum plate 14; the aeration pipe 1 is fixedly connected to the frustum plate 25, and the frustum plate 14 and the frustum plate 25 together form a siphon channel; the aeration pipe 1 is provided with four arc through holes 101, and all the arc through holes 101 are connected to the siphon channel; the aeration pipe 1 is provided with a mounting plate 111, a spring telescopic rod 112, a mounting rod 113, a rotating fan 114, a rotating shaft sleeve 115 and a scraper 116; the aeration net 3 is in an inverted cone shape; the aeration pipe 1 is provided with four arc through holes 2 102, the arc-shaped through hole 2 102 is located above the outer ring side of the aeration net 3; the aeration pipe 1 is fixedly connected to a mounting plate 111; the mounting plate 111 is fixedly connected to a spring telescopic rod 112; the telescopic portion of the spring telescopic rod 112 is fixedly connected to a mounting rod 113; the mounting rod 113 is rotatably connected to a rotating shaft sleeve 115, and the rotating shaft sleeve 115 is rotatably connected to the aeration net 3; the rotating shaft sleeve 115 is fixedly connected to a rotating fan 114; the rotating shaft sleeve 115 is fixedly connected to four scrapers 116 distributed in an annular shape, and all scrapers 116 are in contact with the lower surface of the aeration net 3.

[0018] It also includes a frustum plate three 6; the aeration pipe 1 is fixedly connected with the frustum plate three 6 for expanding the bubble flow area.

[0019] The specific operation of the above-mentioned embodiment 1 is as follows: first, the aeration device is installed on the pipeline of the air conveying equipment in the holding tank, so that the air inlet pipe 2 is connected with the pipeline of the air conveying equipment, and the frustum plate 2 5 contacts the bottom of the holding tank to complete the installation work.

[0020] During aeration, the air delivery device is controlled to deliver high-pressure air into the aeration pipe 1 through the air inlet pipe 2, and then the air will enter the sewage through the mesh of the aeration net 3. The air entering the sewage will turn into dense bubbles and move from the bottom of the water to the surface of the water at the same time, thereby aerating the sewage.

[0021] It should be noted that when air flows through the aeration pipe 1, the rapidly flowing air will cause the aeration pipe 1 to generate negative pressure, and the generated negative pressure will successively draw the sewage at the bottom of the holding tank into the aeration pipe 1 through the siphon channel and the arc-shaped through hole 101, and the sewage entering the aeration pipe 1 will flow back into the holding tank through the mesh of the aeration net 3 driven by the air, so that the organic pollutants at the bottom of the holding tank can flow again in the holding tank, so as to avoid the problem in the prior art that it is difficult for bubbles to push the sewage at the bottom of the holding tank to flow, and the organic pollutants in the sewage are prone to partially sink to the bottom of the holding tank, which makes it difficult to increase the contact opportunity between the organic pollutants at the bottom of the holding tank and aerobic microorganisms, thereby affecting the overall degradation efficiency.

[0022] It also includes a cleaning brush 117; the rotating shaft sleeve 115 is fixedly connected with four cleaning brushes 117 distributed in an annular shape, and all the cleaning brushes 117 are in contact with the upper surface of the aeration net 3, and the cleaning brush 117 and the scraper 116 are arranged in a staggered distribution.

[0023] Each second arc-shaped through hole 102 is provided with an inclined portion 10201 , and the inclined portion 10201 is used to allow air to pass through the second arc-shaped through hole 102 better.

[0024] The scraper 116 is arranged in an arc shape.

[0025] The lower surface of the mounting plate 111 is arranged in an arc-shaped structure, which is used to allow the bubbles that hit the mounting plate 111 to flow to both sides, so as to reduce the obstruction of the mounting plate 111 to the bubbles.

[0026] The specific operation of the above-mentioned embodiment 2 is as follows: Considering that when the sewage at the bottom of the holding tank passes through the aeration net 3, the suspended matter in the sewage will be intercepted by the aeration net 3 and attached to the lower surface of the aeration net 3, that is, the mesh of the aeration net 3 will be blocked, thereby causing the aeration net 3 to be unable to normally aerate the sewage.

[0027] Therefore, by setting the aeration net 3 to be inverted cone shape, opening an arc-shaped through hole 101 on the aeration pipe 1, and adding a mounting plate 111, a spring telescopic rod 112, a mounting rod 113, a rotating fan 114, a rotating shaft sleeve 115 and a scraper 116, after the air contacts the rotating fan 114, the rotating fan 114 will rotate under the push of the air, and the rotating rotating fan 114 will drive the scraper 116 to rotate through the rotating shaft sleeve 115, so that the rotating scraper 116 scrapes the suspended matter on the lower surface of the aeration net 3. However, even if the scraper 116 The suspended matter on the lower surface of the aeration net 3 is scraped off, and the suspended matter is still in the space under the aeration net 3. Sooner or later, it will return to the aeration net 3 and cause blockage. When more and more suspended matter enters the aeration pipe 1, the aeration net 3 is seriously blocked. When the total amount of air entering the aeration pipe 1 is greater than the total amount of air passing through the aeration net 3, the air pressure in the aeration pipe 1 will continue to rise, and the aeration net 3 will move upward on the aeration pipe 1 under the push of the air pressure, and the upward moving aeration net 3 will push the rotating shaft sleeve 115 and the parts connected thereto upward synchronously. The aeration net 3 moves and pushes the telescopic part of the spring telescopic rod 112 to retract. When the aeration net 3 moves to the point where its outer ring side is located above the arc-shaped through hole 102, the rotating scraper 116 scrapes the suspended matter on the lower surface of the aeration net 3. Since the aeration net 3 is set to be an inverted cone and the outer ring side of the aeration net 3 is located above the arc-shaped through hole 102, when the air contacts the aeration net 3, the air is blocked by the aeration net 3, and the air flows along the lower surface of the aeration net 3, and then flows out of the aeration pipe 1 through the arc-shaped through hole 102, and the air flows along the When flowing along the lower surface of the aeration net 3, the air will drive the suspended matter scraped by the scraper 116 to move toward the direction close to the arc-shaped through hole 102, and finally the suspended matter will flow out of the aeration pipe 1 through the arc-shaped through hole 102, so that the aeration net 3 can be self-cleaned according to the blockage situation to prevent the suspended matter from being intercepted by the aeration net 3 and attached to the lower surface of the aeration net 3 when the sewage at the bottom of the holding pool passes through the aeration net 3, that is, the mesh of the aeration net 3 will be blocked, thereby causing the aeration net 3 to be unable to aerate the sewage normally.

[0028] Furthermore, in addition to rotating the scraper 116 through the rotating shaft sleeve 115, the rotating fan 114 will also drive the cleaning brush 117 to rotate. The rotating cleaning brush 117 will push the suspended matter that is blocked in the mesh of the aeration net 3 to separate it from the aeration net 3, so as to dredge the mesh of the aeration net 3 and avoid the problem of the mesh of the aeration net 3 being blocked by the suspended matter.

[0029] When the aeration net 3 is unblocked, the telescopic portion of the spring telescopic rod 112 will push the mounting rod 113 and its connected parts downward to the initial position, so that the outer ring side of the aeration net 3 is located below the arc-shaped through hole 2 102 again, even if the aeration net 3 continues to aerate the sewage.

[0030] Example 2 On the basis of Example 1, Figure 1-Figure 3 As shown, a pressure relief disk 211 is also included; a pressure relief disk 211 for reducing the impact force of the air aeration net 3 is fixedly connected to the aeration pipe 1, and the pressure relief disk 211 is located below the arc-shaped through hole 101.

[0031] The pressure relief disk 211 is a structure that is low in the middle and high around. This structure is used to divert the air so that the pressure relief disk 211 can better relieve the air pressure.

[0032] The aeration pipe 1 is composed of a cylindrical portion 103 and a circular tube portion 104 , and the cylindrical portion 103 and the circular tube portion 104 are detachably connected.

[0033] The specific operation of the above-mentioned embodiment 2 is as follows: Considering that after the air enters the aeration pipe 1 through the air inlet pipe 2, the air will rush toward the aeration net 3 in a concentrated manner, and the aeration net 3 will be subjected to a strong impact force. Under this impact force, the aeration net 3 is prone to not being blocked, and its outer ring side will also be located above the arc-shaped through hole 2 102, thereby causing the aeration net 3 to be unable to normally aerate the sewage.

[0034] Therefore, a pressure relief disk 211 is added so that when air flows into the aeration pipe 1, since the entire aeration pipe 1 is in sewage, that is, sewage exists in the entire aeration pipe 1, when the air passes through the pressure relief disk 211, the air will form bubbles under the action of the pressure relief disk 211, and when the bubbles pass through the aeration net 3, the bubbles will be cut by the mesh of the aeration net 3 to form smaller bubbles, and since bubbles have been formed when the air passes through the aeration net 3, the aeration net 3 will not be pushed to move upward, which can relieve the pressure of the air, so as to avoid the air rushing towards the aeration net 3 in a concentrated manner, and the aeration net 3 will be subjected to a strong impact force, and the aeration net 3 is prone to be not blocked under this impact force, and its outer ring side will also be located above the arc-shaped through hole 2 102.

[0035] It should be noted that, by configuring the aeration pipe 1 to consist of a cylindrical portion 103 and a circular tube portion 104, and the cylindrical portion 103 and the circular tube portion 104 are detachably connected, when the aeration net 3 aerates the sewage for a long time, the aeration net 3 is seriously blocked, that is, when the scraper 116 and the cleaning brush 117 cannot dredge the aeration net 3, the circular tube portion 104 can be manually removed from the cylindrical portion 103, and then the circular tube portion 104 and the parts connected thereto can be taken out from the holding tank to facilitate the replacement of the aeration net 3. At the same time, after the circular tube portion 104 is removed from the cylindrical portion 103, the air inlet pipe 2, the cylindrical portion 103 and the pressure relief disc 211 will form a simple aeration structure, so that during the replacement of the aeration net 3, the simple aeration structure composed of the air inlet pipe 2, the cylindrical portion 103 and the pressure relief disc 211 can continue to aerate the sewage. It should be noted that the simple aeration structure does not have the function of extracting sewage at the bottom of the holding tank.

[0036] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
