the driving mechanism comprises a limiting sleeve 7 fixedly arranged on the top wall of the tank body 1, the top end of the mounting tube 4 penetrates through the top wall of the tank body 1 and extends into the limiting sleeve 7, fan blades 8 are uniformly and fixedly arranged on the part, extending into the limiting sleeve 7, of the mounting tube 4, and a second through hole 30 communicated with the limiting sleeve 7 is formed in the top wall of the tank body 1; the air flow discharged from the second through hole 30 blows the fan blades 8, at the moment, the fan blades 8 drive the mounting pipe 4 to rotate, so that the air bubbles can be ground through the friction between the rotating elastic sleeve 6 and the air bubbles, and the volume of the air bubbles is further reduced;
the balancing weights 9 are uniformly arranged on the outer wall of the elastic sleeve 6, and the balancing weights 9 are positioned at the top and the bottom of the elastic sleeve 6; in the process that the mounting tube 4 drives the elastic sleeve 6 to rotate, the balancing weight 9 has a tendency of being far away from the mounting tube 4 under the action of centrifugal force, so that the elastic sleeve 6 is expanded normally under the combined action of air pressure and centrifugal force at the moment that air is injected into a space between the elastic sleeve 6 and the mounting tube 4;
the air supply mechanism is arranged on the tank body 1 and matched with the mounting pipe 4.

Because the small bubbles can contact with each other and polymerize into large bubbles with larger volume in the floating process, the contact probability of oxygen inside the large bubbles and sewage is lower, the contact probability of the oxygen and the sewage is increased by dividing the large bubbles into the small bubbles, and the purification efficiency can be improved; thereby reducing the cross-sectional area of the jar body 1 through the inflation of elastic sleeve 6 and can prolong the time of microbubble in sewage under the unchangeable condition of microbubble content, further increased the contact probability of oxygen and sewage in the microbubble, further improved purifying effect.
When sewage needs to be purified, firstly, sulfur-containing sewage to be purified is filled into the tank body 1, part of the filter screen 5 is located above the liquid level, then the air pump 3 and the electromagnetic valve 10 are started, the aeration plate 2 is supplied with air through the air pump 3, at the moment, a large number of small bubbles are discharged from the aeration plate 2, the small bubbles float upwards gradually, and in the floating process of the small bubbles, oxygen in the small bubbles is in contact with sulfides in the sewage, so that the sulfides can be purified.
The large bubbles polymerized from the small bubbles contact the filter screen 5 in the floating process, and are divided into the small bubbles again under the action of the holes on the filter screen 5, so that the time for the gas floating on the sewage to maintain the state of the small bubbles is prolonged, and the contact probability of oxygen in the bubbles and the sewage is increased; when the bubble breaks away from the contact with sewage, the gas that is located the liquid level top in jar body 1 passes second through-hole 30 and enters into stop collar 7, and the air current strikes flabellum 8, the surface of flabellum 8 receives vertical ascending impact force this moment, because flabellum 8 slope sets up, consequently vertical ascending impact force will decompose at the horizontal direction with along the inclined plane direction, under the effect of horizontal direction component force, flabellum 8 rotates and drives installation pipe 4 and rotate together, then the air current in the stop collar 7 passes pressure valve 11 and flows to the external world, consequently the pressure in the stop collar 7 is the same with the external world all the time, can continuously flow into stop collar 7 for the air current of jar body 1 inside all the time promptly.
At installation pipe 4 pivoted in-process, installation pipe 4 drives elastic sleeve 6 and installs balancing weight 9 on elastic sleeve 6 and rotates together, the centrifugal force that balancing weight 9 received this moment is less than elastic sleeve 6's elasticity, because balancing weight 9 is in protruding state on elastic sleeve 6's surface, consequently rotate in-process balancing weight 9 striking sewage and play the stirring effect to sewage at balancing weight 9, thereby can be with sewage stirring, be promptly for making the uniform distribution of microbubble in sewage, thereby purifying effect has been improved.
During the rotation, the side wall of the elastic sleeve 6 has centrifugal force, so that the elastic sleeve 6 always has the expansion tendency; similarly, the weight 9 is disposed on the surface of the elastic sleeve 6, so that the weight 9 also has a centrifugal force.
At normal rotation speed, the elastic sleeve 6 can not expand obviously, only when the installation pipe 4 rotates at high speed, the elastic sleeve 6 can deform and expand, the application arranges the balancing weight 9 on the surface of the elastic sleeve 6 only to increase the centripetal force applied to the side wall of the elastic sleeve 6 when the rotation speed of the installation pipe 4 keeps unchanged (if the centripetal force when the elastic sleeve 6 rotates is increased by increasing the thickness (gravity) of the elastic sleeve 6, the elasticity of the elastic sleeve 6 is increased while the thickness of the elastic sleeve 6 is increased, so that the elastic sleeve 6 is difficult to deform when the rotation speed of the installation pipe 4 keeps unchanged, therefore, the centripetal force on the surface of the elastic sleeve 6 is increased by the balancing weight 9, and the elastic sleeve 6 can be ensured to deform in time when the rotation speed of the installation pipe 4 is unchanged), and after the balancing weight 9 is arranged on the surface of the elastic sleeve 6, under the combined action of the centripetal force of the balancing weight 9 and the elastic sleeve 6, the elastic sleeve 6 is in a critical state to be deformed, so that the elastic sleeve 6 can be ensured to expand in time when the pressure exists in the space between the outer wall of the installation pipe 4 and the inner wall of the elastic sleeve 6.
When the content of sulfide in the sewage is high, the electromagnetic valve 10 is opened, the bottom end of the installation pipe 4 is in a sealed state under the action of the pressure valve 11, and at the moment, the gas in the tank body 1 is discharged to the outside through the second through hole 30, the limiting sleeve 7 and the electromagnetic valve 10; after a period of purification, the content of sulfide in the sewage in the tank body 1 is low, the electromagnetic valve 10 is closed, so that the gas in the limiting sleeve 7 can flow only along the mounting pipe 4, the pressure valve 11 can be opened only by needing high gas pressure, when the gas flows along the mounting pipe 4, the gas pressure in the mounting pipe 4 is gradually increased, because the top wall and the bottom wall of the elastic sleeve 6 are fixedly connected with the side wall of the mounting pipe 4, when the gas pressure in the mounting pipe 4 is increased, the gas in the mounting pipe 4 flows into a space formed between the elastic sleeve 6 and the outer wall of the mounting pipe 4 along the first through hole 29, at the moment, under the combined action of the gas pressure and the centrifugal force of the counterweight 9, the elastic sleeve 6 starts to expand, when the elastic sleeve 6 is in a maximum expansion state, the gas in the limiting sleeve 7 continues to enter the mounting pipe 4, at the moment, the pressure valve 11 is opened and starts to discharge redundant gas to the outside for pressure relief, so that the gas pressure in the mounting pipe 4 can always expand the elastic sleeve 6 to the maximum, because the top and the bottom of the side wall of the elastic sleeve 6 are distributed on the top and the bottom of the elastic sleeve 6, the cylindrical space, the elastic sleeve, the inner wall of the tank body is in contact with the sewage, the elastic sleeve, the purification effect of the purification is increased, and the purification effect of the purification is further increased, and the purification of the small cylindrical sewage is increased, and the cylindrical sewage in the cylindrical space of the elastic sleeve 6, and the cylindrical sewage is increased.

By adopting the technical scheme, in the rotation process of the installation tube 4, the installation tube 4 drives the control tube 18 to rotate together through the pressure valve 11, in the process, the sealing gasket 19 on the outer wall of the control tube 18 is intermittently attached to the installation plate 16, and when the sealing gasket 19 is attached to the installation plate 16, gas flowing out of the fourth through hole enters the gas tube 17, so that in the rotation process of the control tube 18, the fourth through hole on the side wall of the control tube 18 can be intermittently communicated with the gas tube 17, namely the gas discharged from the control tube 18 intermittently flows into the box body 13 along the gas tube 17; when the gas content in the box body 13 is increased, the pressure in the box body 13 is increased, at the moment, under the combined action of the air pressure and the one-way valve 14, the sewage in the box body 13 flows into the atomizing spray head 12 along the guide pipe 15 and is sprayed out in a fog state by the atomizing spray head 12, at the moment, the fog-state sewage is contacted with the gas above the liquid level in the tank body 1, and when the water fog is contacted with the gas, the contact probability of the oxygen remaining in the gas and sulfide in the fog-state sewage is increased, so that the purification effect is improved;
because the sealing gasket 19 has a certain thickness, when the sealing gasket 19 is separated from the mounting plate 16, the air pipe 17 is communicated with the outside, and at the moment, high-pressure air in the box body 13 can flow to the outside through the air pipe 17, meanwhile, under the action of air pressure in the tank body 1, sewage in the tank body 1 flows into the box body 13 through the one-way valve 14, and the liquid level in the box body 13 is equal to the liquid level in the tank body 1, so that preparation can be made for the next work; because the height difference between the inner top wall of the box body 13 and the liquid level in the tank body 1 is large, and under the action of the one-way valve 14, the liquid level in the box body 13 is the same as the liquid level in the tank body 1, and the top end of the air pipe 17 extends to the inner top wall of the box body 13, the top end of the air pipe 17 is always positioned above the liquid level in the box body 13, so that the function of preventing sewage in the box body 13 from leaking is achieved.
