Benefit application discloses three float-ball type aerators of one kind and has the oxygenation monitoring system of the aerator, outside the aerator
Rotor electric machine combines to realize sealing by sealing ring and gasket, but since sealing ring and gasket are typically all
Rubber is made, and impregnating for a long time can rot in water, and external rotor electric machine is constantly in rotary state, will increase sealing
The abrasion of circle, so realizing that the effect of sealing is bad by this sealing structure, sealing persistence is poor.
Utility model content
In order to solve the problems, such as that existing external rotor electric machine sealing effect is bad, the utility model provides a kind of sealing effect
Good aerator.
To achieve the goals above, technical solution provided by the utility model is: a kind of aerator with sealing mechanism,
Including external rotor electric machine, impeller is connected on the shell of the external rotor electric machine, the external rotor electric machine is connected with by main shaft
Controller, the junction sealing device of the main shaft and the shell；The sealing device includes the rotating ring and stationary ring of annular shape,
The rotating ring and stationary ring cover on the main shaft, and the rotating ring is close together with the stationary ring and the two can relatively rotate；
The stationary ring is fixed on one end of spring, and the other end of spring is connected on bearing, and the bearing holder (housing, cover) is on the main shaft.
In the above-mentioned technical solutions, it is preferable that the rotating ring and stationary ring are made of ceramics.
Further, sealing element is equipped between the stationary ring and the spring, the sealing element is connect with the spring.
Based on the above technical solution, further, the side of the sealing element is equipped with the groove of annular, described quiet
Ring is set in the groove.
Gasket is equipped between the spring and the bearing as a preferred technical solution, the spring is fixed on described
On gasket, the gasket is connect with the bearing.
Based on the above technical solution, further, the card slot of annular is begun on the gasket, the spring is solid
It is scheduled in the card slot.
Oil sealing is equipped between the rotating ring and the shell as a preferred technical solution,.
In the above-mentioned technical solutions, further, the side of the oil sealing offers the groove of annular, and the rotating ring is stuck in
In the groove.
The beneficial effect of the utility model compared with the existing technology is: the aerator is close by increasing on external rotor electric machine
Seal apparatus, so that the better tightness of external rotor electric machine, so that the service life of aerator is increased, it is specific by mutually tight
The stationary ring and rotating ring that sticks together and can relatively rotate, reach the effect of dual-seal, in addition stationary ring are connected on spring,
Stationary ring and rotating ring can be kept to be in close contact constantly, guarantee the two intimate contact, to achieve the effect that be fully sealed.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the partial enlarged view that A goes out in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As depicted in figs. 1 and 2, a kind of aerator with sealing mechanism, including external rotor electric machine 1, external rotor electric machine 1
It is connected on shell 11 impeller (not drawn in figure), shell 11 is equipped with spindle hole 110, and the main shaft 12 of external rotor electric machine 1 passes through master
Axis hole 110 is connected with controller 3.
Oil sealing 21 is equipped between main shaft 12 and spindle hole 110, oil sealing 21 wraps main shaft 12, plays first layer sealing
Effect offers the groove 211 of annular in the inside of oil sealing 21, is placed with the rotating ring 22 of circular ring shape in groove 211, under rotating ring 22
Side is equipped with stationary ring 23, and stationary ring 23 and rotating ring 22 are all made of ceramics, and surface is smooth, and the two is close together, and opposite can turn
Dynamic, in addition the diameter of rotating ring 22 is greater than the diameter of spindle hole 110, in this way can block completely spindle hole 110, play the second layer
The effect of sealing.
Stationary ring 23 is mounted on the sealing element 24 with annular groove, and the height of stationary ring 23 is greater than the height of sealing element 24
Degree, can prevent so at work sealing element 24 be in contact with rotating ring 22, thus abradable seal member 24.Sealing element 24 and bullet
One end of spring 25 connects, and the other end of spring 25 is connected on the gasket 26 with annular slot, and gasket 26 is arranged in bearing 27
On, 27 sets of bearing on main shaft 12.Under the action of the elastic force of spring 25,23 moment of stationary ring is enabled to be tightly attached to rotating ring 22
Together, aerator is the rotation of shell 11 to which impeller rotates in working principle, when shell 11 rotates, drives 21 turns of oil sealing
It is dynamic, and the rotation of oil sealing 21 drives rotating ring 22 to rotate, and since rotating ring 22 and stationary ring 23 are to contact, does not connect, thus it is quiet
Ring 23 be it is stationary, simultaneously because rotating ring 22 and stationary ring 23 are all made of ceramic, surface is smooth, can rotate for a long time not
It wears, to improve the service life of aerator.
The aerator passes through the stationary ring 23 and rotating ring 22 that is mutually close together and can relatively rotate, and reaches dual-seal
Effect, in addition stationary ring 23 is connected on spring 25, stationary ring 23 and rotating ring 22 can be kept to be in close contact constantly, both is guaranteed
Intimate contact, to achieve the effect that be fully sealed.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
