When the vibration aerator in the embodiment is used, the air inflow of the air inlet pipe 2 can be adjusted, so that the air in the air inlet pipe 2 is kept continuously and is changed, the fixed block 3 is continuously moved up and down under the combined action of the upward lifting force of the air and the gravity of the fixed block, and the air-liquid mixture is changed in the impact force of the fixed block 3 and the swirl blades 4 in the up-and-down movement process, so that the vibration aerator is more favorable for the dispersion of the air in a liquid phase compared with the case that the fixed block 3 and the swirl blades 4 are not arranged.

In addition, after the fluid impacts the rotational flow blades 4, the fluid has certain thrust to the rotational flow blades due to the fact that the rotational flow blades have certain inclination angles, so that the rotational flow blades rotate around the fixed blocks, and the gas-liquid mixing effect is better.

The structure of the fixing block 3 in the present application has no special requirement, and can be opened as long as it can be used for fixing the swirl vanes 4 and can drive the swirl vanes 4 to slide. In this application fixed block 3 moves along the axial, in fact, also can have certain contained angle with the axial, as long as not complete radial, have certain weight in the axial can.

In this embodiment, in order to enable the fixing block 3 to move within a certain range, a sliding rod 5 may be disposed in the barrel 1, at least one end of the sliding rod 5 is fixed to the barrel 1, and the fixing block 3 is sleeved on the sliding rod 5.

The slide bar 5 in this embodiment can be arranged along the axial direction of the cylinder 1, and can also be slightly inclined, although the slide bar 5 is arranged along the radial direction, the gas and the fixed block 3 can be collided, and the dispersion of the gas in the liquid phase is facilitated compared with the case that the fixed block 3 is not arranged, but the fixed block 3 cannot slide under the action of the gas and cannot vibrate, and the dispersion effect is good without the inclined arrangement effect of the slide bar 5. If the sliding rod is not arranged, the stress surface of the fixed block can be set to be a cone shape which is sunken in the box, but the stability is relatively poor.

The 1 exit of barrel in this embodiment can set up the stirring district, improves the mixing effect, also can not set up the stirring district.

In this implementation, slide bar 5 has at least one end to need to fix in barrel 1, and fixed mode can be through connecting rod or connecting block or any other structure, in addition, for making fixed block 3 can not break away from slide bar 5, slide bar 5 can one end be fixed on barrel 1, and the other end is provided with the stopper that prevents fixed block 3 and drop, the shape of stopper, size do not have special requirement, as long as the stopper can't pass the through-hole in the middle of fixed block 3. In addition, the limiting block can also be prolonged to enable the other end of the limiting block to be fixed on the inner wall of the barrel body 1, the two ends of the sliding rod 5 are fixed on the inner wall of the barrel body 1, and the structure of the sliding rod 5 is more stable.

In this embodiment, the lower end of the cylinder 1 is provided with a flow collecting cover 6, the air outlet of the air inlet pipe 2 is located in the flow collecting cover 6, and a liquid phase channel is arranged between the flow collecting cover 6 and the air outlet.

In the process of air intake of the air inlet pipe 2, negative pressure can be generated near the air inlet, and the arrangement of the flow collecting cover 6 is beneficial to leading liquid to be concentrated in the flow collecting cover 6 and enter the cylinder body 1 along with the air intake. The intake pipe 2 in this embodiment may be connected to a compressor, and the intake amount of the gas may be adjusted by adjusting the compressor.

In this embodiment, the cylinder 1 around the fixing block 3 may be provided with at least one abrupt cross section 8, as shown in fig. 2, the inner diameters of the cylinders 1 on two sides of the abrupt cross section 8 are different.

The flow through barrel 1 is adjusted through adjusting the air input and can be so that fixed block 3 produces vibrations, but because the change of flow is continuous, it is progressive, make the vibrations of fixed block 3 also relatively stable, in order to make the vibrations of fixed block 3 violent, set up sudden change cross-section 8 in barrel 1, make barrel 1 internal diameter take place suddenly, regular or irregular grow or reduce, thereby make the velocity of flow of fluid take place the sudden change, the lifting force of vibrations piece takes place the sudden change, thereby make the speed that the vibrations piece rises or descend change. It is preferable that the inner diameter of the cylindrical body 1 is alternately increased and decreased.

In this embodiment, the surface of the fixing block 3 facing the air inlet pipe 2 may be provided with an air scattering member 9.

The gas scattering pieces 9 in this embodiment may be irregular protrusions, scattering rods, or other structures, and mainly disperse gas into smaller bubbles by the impact of the gas and the gas scattering pieces 9, thereby increasing the gas-liquid contact area.

In this embodiment, the cross section of the fixing block 3 may gradually increase along the direction away from the air inlet pipe 2.

The section of the fixing block 3 is gradually increased and can be matched with the arrangement of the abrupt change section 8, so that the fixing block 3 can continuously vibrate when the gas flow is kept stable in a range. Compared with the method for adjusting the gas flow, the method saves energy consumption, and is favorable for prolonging the service life of the air compressor due to the relatively stable power of the air compressor for adjusting the gas flow.

In this embodiment, the swirl vanes 4 may have more than two groups and are sequentially arranged along the sliding rod 5.

The mixing effect can be enhanced by arranging a plurality of groups of swirl vanes 4. In addition, in order to avoid mutual obstruction of the multiple groups of mixed flow blades during rotation as much as possible, the two groups of swirl blades 4 can adopt point contact, so that the contact area is reduced as much as possible, and the friction force is reduced.

In this embodiment, each of the fixing blocks 3 may be correspondingly provided with an elastic member 7, and the elastic member 7 is disposed on a side of the corresponding fixing block 3 away from the air inlet pipe 2.

The elastic member 7 may be made of rubber or a spring, or may be made of other materials having an elastic pad. Because intake pipe 2 just begins when admitting air, gas flow control probably has the error, lead to gas flow too big or undersize, when gas flow is too big, can give 3 very big ascending lifting force of fixed block, make 3 quick rebound of fixed block, probably bump with fixed knot structure or locating part of slide bar 5 upper end, it is long-time, many times, energetically bump probably can make fixed block 3 or connection structure or fiber take place to damage, shorten the life-span of equipment, so set up elastic component 7, reduce the probability that equipment damaged.

In addition, elastic component 7 can the energy storage, and under normal conditions, the power that fixed block 3 moved down can not be greater than gravity, but has increased elastic component 7, and elastic component 7 energy storage may release when fixed block 3 descends, gives fixed one decurrent thrust for fixed 3 decurrent speed also accelerates, improves the striking speed of fixed block 3 and gas, is favorable to gaseous dispersion.
