Specific embodiment
It in the present specification, is the whole relationship with component, aeration between aerator and aeration plate, partition and fixed plate
Disk, partition and fixed plate and connecting rod cooperate, and form aerator.Wherein deposited between aerator and aeration plate, partition and fixed plate
In inner link, therefore, the explanation for being related to aeration plate, partition and fixed plate is suitable for aerator.
It in the present specification, is the convenience of narration and simplicity, aeration plate is horizontally oriented by slotted boss surface
Subject to orientation, think that aeration plate is horizontally oriented at this time.
Similarly, be the convenience of narration and simplicity, generally the partition of plate, fixed plate with the maximum plane of its area at
Subject to horizontal position, this orientation is as its horizontal position, and partition, fixed plate and aeration plate can be folded with maximum area at this time
Set (one is placed on another).
Aeration plate of the invention generally plate, when aeration plate is horizontally oriented, in-between hole is along the vertical direction
Aeration plate is penetrated, is passed through for the connecting rod；Its peripheral edge portion is equipped with the boss for being higher by intermediate portion, so that aeration plate is in
When horizontal direction, global sections are in concave, i.e., the configuration that peripheral edge portion is high, middle section is low；Boss is along aeration plate periphery
Fate cloth, boss surface are equipped with that (i.e. boss is towards the side of aeration disk center and towards on the outside of aeration plate in the interior outside of boss
Side) there is the slot of opening in end so that slot is perforation in boss surface；It is passed through with centre for the connecting rod in boss
Hole between, have the hole penetrated, but the hole is not connected to the hole.The hole penetrated is conducive on being connected on connecting rod
The chamber of the receiving gas of one is formed between multiple aeration plates.When defining the aeration plate, " hole " and " hole " penetrates exposure
Gas disk, except that only role: " hole " is passed through for connecting rod, and " hole " does not connect bar；It should be understood that
, the middle position of fixed plate may not be only in the center of fixed plate.Aeration plate can all have boss with two sides, and boss is provided with
Slot；Only there can also be boss by single side, boss is provided with slot, and another side is smooth.
There are hole in fixed plate of the invention generally plate, centre, pass through for the connecting rod, for consolidating the aeration plate
The fixed extremely connecting rod, it is to be understood that this fixation can be using bolt etc., or spiral shell is equipped in the hole of fixed plate
The realization that is threadedly engaged on line, with connecting rod is fixed.Since the fixation of this situation belongs to conventional mode, in this specification
It does not repeat.In addition, " hole " and " hole " penetrates fixed plate, except that being only when defining the fixed plate
Effect: " hole " is passed through for connecting rod, and " hole " does not connect bar；" hole ", which is opened in when fixed plate is installed to connecting rod, to be corresponded to
The boss of the aeration plate surrounds but position except " hole ".Meanwhile although limiting " hole " among aeration plate,
It is that its position may not be only in the center of aeration plate, as long as " hole " within aeration plate disk, belongs to aeration plate " centre "
Position.
When the slotted boss of aeration plate is horizontally oriented, along the vertical observation vertical with horizontal direction, the profile of slot
It can be V-shaped, rectangle, arc (including semicircle) or other any available forms.There are many distributions on aeration plate for slot
Mode, such as radially (dissipated outward from center；But term " radial direction " does not necessarily imply that aeration plate is that certain is special herein
Fixed shape, such as round) distribution, spiral distribution etc..In addition, slot can be continuous, uniform point in aeration plate boss surface
Cloth, discrete can also be distributed (such as there are spacing for one group of slot and another group of slot, the interval between the spacing and the interior each slot of group is not
Together).The length of slot can be set with processing technology according to actual needs, and if it is radial distribution, the length is boss along diameter
To length.But as long as aeration plate boss surface has the slot of opening equipped with the interior outboard end in boss, so that slot is convex
Platform surface is perforation, then goal of the invention can be achieved, and belong to the range of invention, specific size is unlimited.For example, aeration plate is convex
The groove width that platform surface is equipped with is preferably 0.07mm to less than 0.1mm (i.e. 0.07-0.1mm, but not including that 0.1mm；Such as
For one slot of fruit when width is inconsistent on entire slot length, maxima and minima is within the scope of 0.07mm to less than 0.1mm
Variation), groove depth be 0.1-1.2mm (if a slot when depth is inconsistent on entire slot length, maxima and minima
Change within the scope of 0.1-1.2mm).It is surprising that inventor experiments prove that, as long as groove width is in 0.07mm to small
Between 0.1mm, the height of tube seat is not how, can realize advantageous effect: when being lower than 0.07mm, aeration resistance is big；It is high
In 0.1mm, then outlet is air pocket, and gas effciency is low.0.05-2mm is divided between slot.For example, boss height (from
Aeration plate mid-plane is started) it is 0.1-2.0mm, the width of boss is (by boss along the rectilinear direction outside by aeration disk center
Upper meter) it is 0.5-30mm.Preferably, boss height is greater than the depth of slot, facilitates in the space that boss surrounds to be formed in this way
The chamber of gas is stored, conducive to the stable operation of aeration process.
Hole among aeration plate can be circle, rectangle, ellipse etc., and preferably circular, size is preferably somewhat greater than
The outer diameter of connecting rod is easily installed in this way to connecting rod, and the shape in hole is preferably consistent with the exterior contour of connecting rod, but
This is only for processing and consideration easy to assembly (when connection, can be using gasket etc., the junction of sealing hole and connecting rod).
The size of aeration plate, thickness are unlimited, can determine according to actual needs.For example, aeration disk diameter is (when non-circular, by inscribed circle
Diameter meter) it can be 5-250mm, thickness is, for example, 1-5mm.
Preferably, aeration plate is equipped with fixing device, for example, in two adjacent aeration plates, one of aeration plate
Recess is equipped on the surface that boss surrounds, another aeration plate is equipped with protrusion corresponding with the recess on corresponding surface, dashes forward
Rising can be inserted in recess, thus, it is possible to effectively prevent in the play displacement in aeration process between aeration plate, thus reliably
Work.

The region of disk boss and it is intermediate for the connecting rod across hole area meter, the area in hole accounts for 5-60%, preferably 10-
45%.Hole can have multiple, and the area in each hole may be the same or different, it is preferred that identical, equally distributed for area
Hole.Obviously, the fixed plate in no hole is suitable in connecting rod plug at end part aeration plate, and has the fixed plate in hole to be suitable for as aeration
With the entrance of gas.
There can also be partition between aeration plate of the invention, form aeration opening with the slot on aeration plate boss by it, it is special
It is not that can reduce the size of the aeration opening of slot formation (such as using partition when aeration plate and aeration plate are that slot is stacked against slot
The slot of the slot of one aeration plate of fruit against another aeration plate forms aeration opening, then an aeration is formed between single slot and slot
Mouthful；And slot-partition-slot configuration then forms two aeration openings, the i.e. aeration opening that two slots-plate is formed).Partition shape and there is hole
Fixed plate it is similar, generally there are hole in plate, centre, pass through for the connecting rod to be fixed to the connecting rod；It hole can be square
Just gas flows through.When specifically used, it might even be possible to directly using have hole fixed plate (in this case, partition with
Fixed plate has no essential distinction, and only purposes is different: partition is used for isolated aeration disk, to form aeration opening；And fixed plate is used
It in immobilized film disk to connecting rod, is usually located on the outside of aeration plate, such as in the end of connecting rod).
An embodiment according to the present invention, the connecting rod, aeration plate, partition and fixed plate are by metal (aluminium, iron
Deng), plastic material (such as the materials such as polyethylene, polypropylene, polymethyl methacrylate, polyformaldehyde, polycarbonate) or hard rubber
Glue is made.
