Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an aeration device for sewage treatment with an anti-blocking structure. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse.

[0003] The activated sludge process is one of the most common biological treatment methods. Sewage is mixed with activated sludge (containing a large number of microorganisms), and the microorganisms decompose the organic matter in the sewage under aerobic conditions. The microbial communities such as bacteria and protozoa in the activated sludge cooperate with each other. Bacteria decompose organic matter, and protozoa feed on bacteria. Through this ecological relationship, the organic matter in the sewage is gradually decomposed and transformed. For example, in urban sewage treatment plants, most of the organic matter removal is completed by the activated sludge process.

[0004] The sludge in the sludge tank often blocks the aeration holes, slowing down the efficiency of sewage treatment.

[0005] The patent with the announcement number CN115367866B discloses an aerator with anti-blocking effect, including a hollow shell and a microporous head fixedly installed on the upper end of the shell, wherein the microporous head is provided with a plurality of microporous structures for separating airflow; the bottom end of the shell is provided with a connecting port connected to the inside of the shell; a supporting cylinder is fixedly provided in the middle of the shell, and the supporting cylinder is fixedly connected to the inner wall of the shell through a plurality of partitions arranged around the periphery of the supporting cylinder; the interval area between the plurality of partitions forms an airflow channel; a plurality of blocking plates are arranged around the upper end of the supporting cylinder, and one end of each blocking plate is hinged with the upper end of the supporting cylinder. The support tube is provided with a driving shaft inside, the upper end of the driving shaft is movably connected with the blocking plate, and the driving shaft is driven by a driving member to move up and down; the driving shaft moving downward drives several blocking plates to enter a blocking state, and several blocking plates in the blocking state block the airflow channel; the driving shaft moving upward drives several blocking plates to enter an open state, and several blocking plates in the open state cancel the blockage of the airflow channel; a water bag is fixed on the lower plate surface of each blocking plate; a pressure combination valve is provided around the outer shell, and the pressure combination valve is connected to the water bag through a hose. The improved aerator structure reduces the problem of external impurities blocking the micropores due to negative pressure when the fan is turned on or off.

[0006] In the above technical solution, the microporous structure on the microporous head is arranged vertically, and the aeration equipment is generally placed at the bottom of the sludge pool. Although the suction problem caused by the negative pressure can be controlled by the sealing plate when the fan is turned on or off, the embedding problem of the sludge under the action of gravity cannot be eliminated. Therefore, there is still a risk of blocking the aeration holes. An aeration equipment for sewage treatment with an anti-blocking structure is urgently needed to solve the above-mentioned problems.

[0068] The lower part of the aeration assembly is provided with an inner seat mechanism 2 adapted to be placed in the bottom box 101;

[0069] The inner seat mechanism 2 includes an inner seat 201 adapted to the bottom box 101, and the four corners of the upper surface of the inner seat 201 are fixedly connected with an adaptor 202, and the inner surface of the adaptor 202 is sloped, which is convenient for use with the travel route of the aeration component, and the outer surface of the adaptor 202 is in line with the bottom box 101;

[0070] A first gear 203 meshing with the second gear 508 is fixedly connected to the middle of the lower surface of the inner seat 201 , and a resistance pad 204 in contact with the lower inner wall of the bottom box 101 is arranged in a ring shape on the lower surface of the first gear 203 . The resistance pad 204 is made of anti-slip material.

[0071] A first annular groove 205 is provided in the middle of the upper surface of the inner seat 201 and is adapted to fit with the bin ring 301. A second annular groove 206 is provided in the middle of the lower inner wall of the first annular groove 205.

[0072] The middle part of the inner arc wall of the second annular groove 206 is inwardly concave with a first column groove 207, and the middle part of the outer arc wall of the second annular groove 206 is inwardly concave with a second column groove 208;

[0073] The first small columns 209 are evenly and evenly arranged in a circular pattern inside the first column slot 207. Each first small column 209 is hinged to a column plate 210 through a spring. The end of the column plate 210 away from the first small column 209 is hook-shaped and adapted to be hooked with a second small column 211. The second small columns 211 are evenly and evenly arranged in a circular pattern inside the second column slot 208.

[0074] The tooth column 507 passes through the lower storage plate 302 and the storage ring 301 in sequence, and the tooth column 507 is adapted to be inserted into the second ring groove 206 .

[0075] The working principle of the present invention is as follows:

[0076] When not started, the air film 306 is recessed inwardly under the pressure of the sludge water inside the bottom box 101. At this time, the outer port of the air cylinder mechanism 4 is closed under the action of the hole ring 405, thereby directly isolating the sludge water. In this way, when the wheel fan assembly is started by the motor 104, the phenomenon of back suction through the air cylinder mechanism 4 is avoided, thereby improving the safety of the equipment during initial startup.

[0077] The second gear 508 is driven to rotate by starting the motor 104, and the first gear 203 remains stable under the action of the resistance pad 204. The second gear 508 is meshed with the first gear 203, so that the second gear 508 rotates along the periphery of the first gear 203, and the tooth column 507 slides along the second annular groove 206. When the tooth column 507 contacts the column plate 210, it can pry open the connection between the column plate 210 and the second small column 211. When the tooth column 507 leaves the column plate 210, under the action of the spring hinge between the first small column 209 and the column plate 210, it automatically returns to the connection with the second small column 211, and further drives the bin ring 301 to move along the first annular groove 205, so that the aeration component rotates and aerates inside the bottom box 101, thereby improving the comprehensiveness of the aeration equipment.

[0078] The device draws air into the air film 306 through the air pipe 501 by the rotation of the wheel fan assembly, and then guides the air out through the air cylinder mechanism 4. Therefore, when the wheel fan assembly is started and stopped, the air film 306 will form a concave or convex structure according to the instability of the internal and external pressures, and the outer frame 303 and the inner frame 304 distributed on the inner and outer sides of the air film 306 will control the excessive deformation of the air film 306, thereby protecting the air film 306 during the operation of the equipment and increasing the service life of the equipment.

[0079] When the wheel fan assembly is started, air is pumped into the air film 306 through the air pipe 501, causing the air film 306 to expand and form an outward convex structure. At this time, the outer end of the rocker arm 402 is expanded by the pulling of the pull rope 403 and the deformation of the surface of the air film 306, and further drives the hole ring 405 to expand, thereby opening the cross-opening pad 406 to form an air hole, and the gas is gradually introduced into the bottom box 101 through the air cylinder mechanism 4 to mix with the sludge water, so that the air cylinder mechanism 4 is automatically opened after the wheel fan is started, thereby improving the automation efficiency of the equipment.

[0080] The rotation of the air pipe 501 drives the stirring plate 503 to further stir the sludge water inside the bottom box 101, and cooperates with the revolution of the aeration component to fully and effectively stir the sludge water inside the bottom box 101, strengthen the mixing of sludge water and external air through the upper port of the bottom box 101, and further improve the aeration efficiency.

[0081] During the process of the impeller assembly slowly rotating until it stops, due to the internal and external pressure adjustment of the air film 306, the air film 306 is gradually transformed from a convex structure to a concave structure, and in this process, the outer end of the rocker arm 402 is correspondingly aggregated. When the outer end of the rocker arm 402 shrinks less, it is closer to the cleaning column 305, and the sludge water collected before the rocker arm 402 is completely closed is squeezed out through the cleaning column 305, thereby further improving the anti-blocking performance of the equipment.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
