Embodiment
The utility model is further illustrated with reference to embodiment：
As shown in embodiment in Fig. 1 and Fig. 2, this sealing airlock includes shell 1, impeller 2；The centre of the impeller 2
Horizontal rotating shaft 21 is designed with, the impeller 2 is assemblied in the shell 1, the rotating shaft 21 and the rotatable assembling of the shell.
The upper and lower side of the shell 1 is respectively designed with charging aperture, discharging opening, and charging aperture, discharging opening of the shell about 1 pass through flange and its
Its production equipment is connected.Material to be transported enters from upper feed inlet, is exported from bottom discharging opening.
The side of the shell 1 is designed with motor 3, and the end of the motor 3 passes through sprocket wheel, chain and the impeller 2
Rotating shaft 21 is connected；Sprocket wheel, chain transmission structure can realize synchronous driving so that the impeller feeding in airlock is more equal
It is even.The both ends of the shell 1 are equipped with side lid 4, and the through hole with the rotating shaft 21 assembling is machined among the side lid 4, described
Passed sequentially through from outer end to the inner oil immersion packing 5 and the labyrinth bush 6 of through hole assemble with the rotatory sealing of rotating shaft 21, the side
The inner side of lid 4 is equipped with the pressing plate 61 for compressing the labyrinth bush 6, and the centre of the pressing plate 61 is revolved by O-ring 7 and rotating shaft 21
Turn sealing assembling, the outside of the pressing plate 61 is assembled by the inner seal of O-ring 7 and the side lid 4；Outside the side lid 4
Side is designed with the inlet end 41 for leading to the position of labyrinth bush 6, and the inlet end 41 is connected by tracheae with high-pressure gas circuit.
This sealing airlock is realized three-layer sealed by the O-ring of oil immersion packing, labyrinth bush and the pressing plate, is made
It is more preferable to obtain the sealing effectiveness of airlock, while the high-pressure gas circuit is passed through height by the inlet end to the position of labyrinth bush 6
Calm the anger, high pressure gas can flow out from the both sides of labyrinth bush 6, can outwards be blown from oil immersion packing 5 to the high pressure gas of the outside of labyrinth bush 6 outflow
Go out, can be blown into the high pressure gas of the inner side of labyrinth bush 6 outflow inside the part watt gram 1 of pressing plate 61, the so described end cap both sides of impeller 2
Axial end realizes hermetic seal, can prevent thinner powder from being flowed out from the inside of shell 1, the dust being also possible to prevent outside airlock
Enter from the both sides shaft end of impeller 2 in shell 1.This air-tight structure cooperation O-ring 7, elastic compensating packing compression seal, three
Seal form of different nature, good leak tightness, for the strong material of superfine powder, good fluidity, permeability, airlock inside gas
Press big occasion, the occasion of malleation conveying, it is ensured that not material leakage, change the single seal form of tradition.Simultaneously because connect using non-
Tactile hermetic seal and compensation packing compression seal, equipment is substantially non-maintaining, for bringing great convenience using client.
As shown in Figures 2 and 3, rotating shaft 21 of the impeller 2 along level is from left to right designed with perpendicular to described turn successively
The leaflet piece 22 of axle 21, be evenly equipped with axle blade 23 along the rotating shaft 21 is circumferential between leaflet piece 22 described in any two, it is horizontal to
The adjacent mutual dislocation of axle blade 23.Such design to initially enter leaflet from the material that the upper feed inlet of shell 1 flows into
Sub-material chamber between piece 22 and axle blade 23, because the dislocation of the axle blade 23 designs so that the sub-material chamber is also dislocation
Arrangement, the material so entered from upper feed inlet are first dispersed to each sub-material intracavitary, and in charging, charging it is uneven
The mainly cross blade of impeller 2, enters that material that gating location drops is erratic to be caused, and in the structure shown here, often
The secondary material to drop in big impeller 2 can all respectively enter the sub-material chamber of dislocation, and due to the reason that misplaces, adjacent material cavity can't be same
Material is walked out of, can thus substantially reduce the fluctuation of unit discharging.So that airlock discharging is more uniform.
In specific design, as shown in figure 1, the front side of the shell 1 is machined with the horizontal return air inlet to bar shaped, described time
It is equipped with the return air shell 11 inside return air inlet with the ft connection of shell 1, the upper design air outlet of return air shell 11 on air port,
Impeller 2 in the shell 1 turns clockwise, and the return air shell 11 of the return air inlet connects with the position of impeller 2 after discharging, this
When, pressure that return air shell 11 can be in the balanced impeller 2 prevents existing when impeller 2 from rotating to charging aperture with gating location
Pressure differential, it is suddenly fast suddenly slow can so to prevent that pressure differential from causing material to be fed in gating location, the charging of the airlock is more
What is added is uniform.
In specific design, as shown in figure 1, the front side of the shell 1 is equipped with pressure regulator valve 12, the high-pressure gas circuit passes through
Pressure regulator valve 12 is connected with the inlet end 41, and the high-pressure gas circuit accesses the pressure regulator valve 12 by irradiation modules.Pass through pressure regulation
The user of valve 12 can easily check out its admission pressure of high pressure, the convenient pressure difference controlled inside and outside airlock, and described
The design of irradiation modules so that the gas entered in the shell 1 is all in drying regime, so in airlock feeding process
In, the pollution of material will not be caused, using effect is more preferable.
In specific design, as shown in Figure 2 and Figure 4, the outside of the side lid 4 is axially stretched by the pole 42 of more than two
Go out to be connected with the mounting ring 43 coaxial with the side lid 4, bearing holder (housing, cover) 44, the bearing holder (housing, cover) are fixedly connected with the mounting ring 43
44 are assembled by bearing 8 and the phase of rotating shaft 21；The relatively described rotating shaft 21 of the pole 42 is circumferential uniform.So in the Blowing stopper
In, main revolving part bearing 8 only passes through closure elements away from the shell 1 and side lid 4 between side lid 4 and rotating shaft 21
Contact, main stress when so described impeller 2 rotates are concentrated on the bearing 8, so that the closing member of the Blowing stopper
Part stress equalization, abrasion is smaller, and service life is longer.Simultaneously because revolving part bearing 8 is outside by pole 42 and mounting ring 43
Stretch out, be more prone to change when bearing 8 wears, when safeguarding or changing bearing 8.Miscellaneous part need not be removed, is only needed
It can carry out changing bearing 8 with bolt ejection bearing block.Safeguard enhanced convenience.
In specific design, as shown in Fig. 2 the outside of the bearing holder (housing, cover) 44 is equipped with bearing gland 45, the bearing 8
Both sides are respectively fitted with outside framework oil seal 81.One outside framework oil seal 81 is assemblied on the bearing gland 45, an outside framework oil seal 81
It is assemblied in the bearing holder (housing, cover) 44, lubricating oil can be enclosed in the bearing 8 by two outside framework oil seals 81 so that the bearing
Frictional force during 8 work is smaller, and service life is longer.
In specific design, as shown in Fig. 2 the inner side of the mounting ring 43 is equipped with spring capping 48, the spring pressure
