The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in figures 1 to 3, an aeration device for a sewage pool comprises an aeration body 1, a membrane 2, a fixing part 3 and a sealing ball 4, the aeration body 1 comprises an air inlet cavity 11, a connecting pipe 12 and an air outlet cavity 13, the sections of the air inlet cavity 11 and the air outlet cavity 13 are funnel-shaped, the connecting pipe 12 is cylindrical, two ends of the connecting pipe 12 are respectively communicated with the smaller ends of the air inlet cavity 11 and the air outlet cavity 13, the section of the diaphragm 2 is arc-shaped, a plurality of micropores 21 are arranged on the diaphragm 2, the diaphragm 2 is arranged at one end of the air outlet cavity 13 far away from the connecting pipe 12, the fixing part 3 is covered on the diaphragm 2 and is detachably connected with the air outlet cavity 13, one end of the diaphragm 2 adjacent to the air outlet cavity 13 is provided with a connecting rod 22, the other end of the connecting rod 22 is connected with a sealing ball 4, and the sealing ball 4 is abutted to the connecting part of the connecting pipe 12 and the air outlet cavity 13. Specifically, in the present embodiment, the squib body 1 is integrally cast of nodular cast iron, the strength of the nodular cast iron is comparable to that of the cast steel, the tensile strength of the nodular cast iron is 60k, and the corrosion resistance and oxidation resistance of the nodular cast iron exceed those of the cast steel. One important reason for the choice of ductile iron is that ductile iron is less costly than cast steel. The low cost of nodular cast iron makes the material more popular, the casting efficiency is higher, and the machining cost of the nodular cast iron is lower. It should be noted that, because the aeration body 1 is placed at the bottom of the sewage tank for a long time and the environment is severe, the outer surface of the aeration body made of the ball-milling cast iron is subjected to rust prevention treatment, and black nickel can be chemically plated or phosphating treatment can be performed. Furthermore, the aeration body 1 comprises an air inlet cavity 11, a connecting pipe 12 and an air outlet cavity 13, which form an hourglass shape, the air inlet cavity 11 is communicated with a pipeline (not shown in the figure), when pressurized air enters the connecting pipe 12 through the air outlet cavity 13, because the volume of the connecting pipe 12 is far smaller than that of the air inlet cavity 11, when the air enters the connecting pipe 12, the flow rate is further increased, the sealing ball 4 abutted against the connecting pipe 12 is lifted, it should be noted that the sealing ball 4 is made of rubber, and when the sealing ball is abutted against the connecting pipe 12, the air tightness is good, and when aeration is not performed, the sealing ball can be tightly attached to the joint of the connecting pipe 12 and the air outlet cavity 13 by means of the pressure transmitted by the water pressure diaphragm 2 and the connecting rod 22, so that sewage is prevented from entering the air inlet cavity 11 through the connecting pipe 12. Further, when the high pressure gas enters the inlet chamber 11, the rubber diaphragm 2 starts to bulge upward, i.e., toward the side facing away from the outlet chamber 13. The micropores 21 are opened, the flow rate of the gas is increased because the openings of the micropores 21 are small, air which is sprayed into the sewage pool is easy to generate bubbles, and the air and sewage dissolve oxygen, so that microorganisms in the sewage pool are easy to play an oxidation role, and the sewage pool is purified. When the aeration is finished, the pipeline is not aerated, the membrane 2 moves downwards to the eardrum under the action of water pressure, but partial pressure can be effectively offset due to the existence of the connecting rod 22 and the sealing ball 4, the phenomenon that the opening of the micropores 21 is too large due to too large change of the membrane 2 is avoided, and sewage permeates into the air outlet cavity 13 through the micropores 21.

As shown in fig. 1 to 3, a plurality of spoilers 23 are further disposed on one side of the diaphragm 2 away from the air outlet cavity 13. Specifically, the soft spoiler 23 is arranged on the diaphragm 2, and when high-pressure gas at the gushing position in the micropore 21 swings back and forth in the sewage tank along with the high-pressure gas, more foam is generated, and the oxygen dissolving efficiency is increased.

As shown in fig. 1 to 4, a connecting portion 24 is disposed at an edge of the diaphragm 2, a groove 241 is disposed at one side of the connecting portion 24 adjacent to the fixing member 3, the fixing member 3 includes a pressing edge 31 and a tooth cylinder 32, the tooth cylinder 32 is vertically connected to an outer ring of the pressing edge 31, and an annular protrusion 311 is disposed at an inner side of the pressing edge 31 corresponding to the groove 241. Specifically, in this embodiment, in order to avoid sewage from entering from the connection between the fixing member 3 and the aeration body 1, the connecting portion 24 is disposed at the edge of the membrane 2, and the connecting portion 24 is used as a sealing member, so that when the pressing edge 31 is mounted on the connecting portion 24, the protrusion 311 is tightly attached to the groove 241, the contact area is increased, and sewage can be effectively prevented from entering from the connection between the pressing edge 31 and the air outlet cavity 13.

As shown in fig. 1-2, the inner side of the tooth cylinder 32 is provided with a thread structure, one end of the air outlet cavity 13 departing from the connecting pipe 12 is provided with an installation cylinder 131, and the outer side of the installation cylinder 131 is provided with a thread structure. Specifically, with a tooth section of thick bamboo 32 and an installation section of thick bamboo 131 threaded connection, avoid using other connecting pieces, for example, rivet bolt etc. avoided the time for a long time, the connecting piece is ageing rusty, the tooth section of thick bamboo 32 and the inseparable degree of being connected of an installation section of thick bamboo 131 reduce.

As shown in fig. 4, a waterproof cloth 25 is adhered to one side of the diaphragm 2 adjacent to the air outlet cavity 13. Specifically, in this embodiment, waterproof cloth 25 is formed by the PTFE membrane with the cloth is compound, and waterproof ventilation effect is good, can further prevent that sewage from getting into in the air outlet cavity 13 through micropore 21.
