DETAILED DESCRIPTION

[0025] See also Figures 1 to 5A micro-nano aeration device for an aerobic pool in a sewage treatment plant comprises: an aerobic pool body 1, a plurality of micro-nano bubble generator groups and a plurality of mud-blocking plates 201. A pool plate 101 is installed on the bottom wall of the aerobic pool body 1, and a plurality of mounting plates 2 are arranged on the pool plate 101; a plurality of micro-nano bubble generator groups are mounted on the plurality of mounting plates 2 in a one-to-one correspondence, and each of the micro-nano bubble generator groups comprises a plurality of micro-nano bubble generators, and an air outlet is arranged above the micro-nano bubble generator, and the bottom of the micro-nano bubble generator is connected to an air supply pipe 301, and the other end of the air supply pipe 301 is connected to an air supply device; and a plurality of mud-blocking plates 201 are covered on the air outlets of the plurality of micro-nano bubble generators in a one-to-one correspondence, and the lower end of each mud-blocking plate 201 is connected to the mounting plate 2 through an elastic member 210, so as to have an upward and downward movable stroke.

[0026] When the micro-nano bubble generator group is working, gas is provided to the micro-nano bubble generator through the air supply device. When the gas is ejected from the air outlet of the micro-nano bubble generator, an upward thrust is generated on the mud barrier plate 201 at the air outlet, causing the mud barrier plate 201 to move upward, and the gas output by the micro-nano bubble generator group enters the interior of the aerobic tank body 1, thereby increasing the oxygen inside the aerobic tank body 1. When the air supply device stops providing gas to the micro-nano bubble generator group, the mud barrier plate 201 loses external force and moves downward under the dual force of gravity and the elastic member 210, and then covers the micro-nano bubble generator group, thereby reducing the sediment inside the aerobic tank body 1 from accumulating on the air outlet of the micro-nano bubble generator when the micro-nano bubble generator group is not working.

[0027] Furthermore, a blocking block 207 is fixedly connected to the lower end of the mud barrier 201, and the outer diameter of the blocking block 207 is adapted to the inner diameter of the air outlet of the micro-nano bubble generator, so that when the mud barrier 201 moves downward, the blocking block 207 is inserted into the air outlet of the micro-nano bubble generator.

[0028] The blocking block 207 can block the air outlet of the micro-nano bubble generator, and when the micro-nano bubble generator group is not working, the sediment inside the aerobic tank body 1 can be reduced from accumulating on the outlet of the micro-nano bubble generator.

[0029] Preferably, the blocking block 207 is configured in a cone shape.

[0030] On the one hand, when the conical blocking block 207 moves upward, it can guide the nanobubbles emitted by the micro-nano bubble generator group, so that the nanobubbles can be better diffused inside the aerobic tank body 1; on the other hand, when the conical blocking block 207 moves downward, it can have a better guiding effect, so that the blocking block can enter the air outlet of the micro-nano bubble generator more smoothly.

[0031] Furthermore, a magnetic attraction ring 208 is installed below the mud blocking plate 201 , and a magnetic attraction portion corresponding to the position of the magnetic attraction ring 208 is provided at the upper end of the micro-nano bubble generator.

[0032] By providing the magnetic attraction ring 208, the mud-blocking plate 201 can be adsorbed with the magnetic attraction part of the micro-nano bubble generator, so as to fix the position of the mud-blocking plate 201 on the micro-nano bubble generator, so that the position of the mud-blocking plate 201 will not be offset. Specifically, the magnetic attraction part can be a magnetic ring that is arranged at the edge of the micro-nano bubble generator to be attracted to the magnetic attraction ring 208 in opposite sex, or it can be arranged to be a metal material.

[0033] Specifically, refer to Figure 5 As shown, the elastic member 210 is a tension spring; fixed tubes 204 are installed on both sides of the micro-nano bubble generator, and fixed blocks 209 are installed on the bottom of the fixed tubes 204. The lower end of the tension spring 210 is fixed on the fixed block 209, and the upper end of the tension spring 210 is connected to a sliding block 211, and the sliding block 211 is slidably connected to the inner wall of the fixed tube 204. A support rod 212 is connected to the upper side of the sliding block 211, and the upper end of the support rod 212 is fixedly connected to the mud baffle 201.

[0034] When the air supply stops supplying gas to the micro-nano bubble generator, the mud-blocking plate 201 loses external force and moves downward under the dual force of gravity and the tension spring 210, and then covers the micro-nano bubble generator. By setting the sliding block 211 to slide in the fixed tube 204 and setting the elastic member 210 in the fixed tube, the upward and downward movement of the mud-blocking plate 201 is more stable.

[0035] In this embodiment, each group of micro-nano bubble generators includes a first micro-nano bubble generator 202 and a plurality of second micro-nano bubble generators 203 , and the plurality of second micro-nano bubble generators 203 are arranged in a circle around the first micro-nano bubble generator 202 .

[0036] By setting the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203, the oxygen content inside the aerobic tank body 1 can be increased, and the metabolism of the microorganisms inside the aerobic tank body 1 can be promoted, so that the organic matter can be efficiently degraded and the nitrogen and phosphorus can be treated. The second micro-nano bubble generator 203 is arranged in a circular shape so that oxygen can be fully in contact with the microorganisms inside the aerobic tank body 1.

[0037] Furthermore, an air intake pipe 3 is connected through the lower side of the first micro-nano bubble generator 202, and the air intake pipe 3 is connected to the air supply pipe 301. An annular tube 205 is connected through the plurality of second micro-nano bubble generators 203, and the first micro-nano bubble generator 202 and the annular tube 205 are connected through a plurality of branch pipes 206.

[0038] Specifically, the air supply device transmits the gas to the air inlet pipe 3 through the air supply pipe 301, and then transmits it to the first micro-nano bubble generator 202. The first micro-nano bubble generator 202 transmits it to the annular pipe 205 through multiple branches 206, and then transmits it to the second micro-nano bubble generator 203 through the annular pipe 205, so that the gas can circulate inside the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203.

[0039] Specifically, a plurality of the mounting plates 2 are installed on the pool plate 101 in a rectangular shape and are evenly spaced apart. The air inlet pipe 3 is arranged in a U shape. The two ends of the air inlet pipe 3 are respectively connected to a plurality of first micro-nano bubble generators 202 , and the middle part is connected to the air supply pipe 301 .

[0040] The gas supplier provides gas to the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 through the gas supply pipe 301 and the gas inlet pipe 3, so that the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 can work normally and generate nano-scale bubbles.

[0041] Furthermore, a temperature detector 4 and a pH detector 402 are installed on the side wall of the aerobic pool body 1 . A floating board 403 is sleeved on the outside of the pH detector 402 . The floating board 403 is connected to the side wall of the aerobic pool body 1 through a fixing rope 401 .

[0042] The temperature of the liquid inside the aerobic tank body 1 can be monitored in real time by the temperature detector 4 , and the pH value of the liquid inside the aerobic tank body 1 can be detected by the pH detector 402 .

[0043] Specifically, during use, the mud-blocking plate 201 is provided on the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203, and the mud-blocking plate 201 is connected to the inside of the fixed tube 204 through the sliding block 211. When the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 are working, gas is provided to the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 through the air supply device. When the gas is ejected from the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203, an upward thrust is formed inside the aerobic tank body 1, causing the mud-blocking plate 201 to move upward, and the gas output by the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 enters the inside of the aerobic tank body 1, thereby increasing the oxygen inside the aerobic tank body 1. When the air supply device stops the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 from providing gas, the mud barrier 201 loses external force and, under the dual force of gravity and the tension spring 210, the mud barrier 201 moves downward and then covers the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203, so that when the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203 are not working, the sediment inside the aerobic tank body 1 is reduced from accumulating on the air outlets of the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203, thereby avoiding affecting the normal use of the first micro-nano bubble generator 202 and the second micro-nano bubble generator 203.
