Description
Technical field
The utility model belongs to powdery paints production and processing field, and in particular to a kind of rotary screen.
Background technology
Rotary screen primary structure include outer housing, motor, connect with motor output end turn screen axis, another positioned at screen axis is turned
End turns sieve end cap, turns to be provided with feeding auger and scraper on screen axis, sieve is cased at scraper, turns between screen axis and turn sieve end cap
It is connected by bearing.Material inlet, coarse powder outlet, fine powder outlet are provided on outer housing, fine powder outlet enters as finished powder
The process of next weighing and bagging.
Above structure, if being not added with sealing structure, bearing that powder is easily accessible in motor, turn screen axis with turn sieve end cap it
Between bearing at, frictional heating makes dust be solidificated at bearing, and bearing is caused to block, electrical fault, influences to use.
At present, palace shape sealing or outside framework oil seal, but both modes are mainly taken, since friction leads to sealing element itself
Service life it is very short, or so week just needs replacing seal member, and frequency of maintenance is too high.
Invention content
The utility model provides a kind of rotary screen, by the form of gas wall, prevents to solve the problems in background technology
Dust enters at bearing.
The technical solution of the utility model is：
Rotary screen, what is connect including motor, with motor output end turns screen axis, it is characterised in that：The both ends for turning screen axis
It is both provided with seal assembly, the seal assembly is sleeved on the lip packing turned on screen axis, for fixing lip packing including two
Sealing gland seat, the suction nozzle that is arranged on sealing gland seat, the suction nozzle is located between two lip packing.
Preferably, the lip packing and turn to be additionally provided with sealing shroud between screen axis, the sealing shroud, which is fixed on, turns screen axis
On, transition cooperation between the lip packing and sealing shroud.
Preferably, the sealing shroud is detachably secured to turn on screen axis.
Preferably, for the sealing gland cover for seat outside lip packing, lip packing includes two lips of two lips and connection
Middle interconnecting piece, the middle interconnecting piece is detachably secured on sealing gland seat.
Preferably, the suction nozzle is connect with inlet duct.
The utility model advantage is：（1）High pressure gas is formed into two lip packing 11, sealing shroud 12 and sealing gland seat 9
Confined space in, high pressure gas can eject between lip and sealing shroud 12, formed gas wall, prevent dust from entering.（2）Even if
Friction can cause lip packing 11 to be worn between lip packing 11 and sealing shroud 12, the formation of gas wall be nor affected on, so as to extend
The part replacement period reduces frequency of maintenance.（3）The presence of sealing shroud 12 protects and turns screen axis 2, prevents lip packing 11 direct
Abrasion caused by turning screen axis 2, avoid the problem that replacing it is whole turn screen axis 2 bring it is of high cost, and when sealing shroud 12 is worn,
Sealing shroud 12 is only needed replacing, reduces maintenance cost.（4）Air inlet can also cool down to lip packing 11, because lip is close
High-speed friction can generate heat between envelope 11 and sealing shroud 12, and high temperature can reduce the service life of lip packing 11, therefore, airtight
Envelope can also play the role of extending the service life of lip packing 11.

Specific embodiment
As shown in Figure 1, rotary screen primary structure include outer housing, motor 1, connect with 1 output terminal of motor turn screen axis 2,
Positioned at turn sieve end cap 8 for turning 2 other end of screen axis, turn to be provided with feeding auger 6 and scraper 7 on screen axis 2, sieve be cased at scraper 7,
Turn screen axis 2 and turn to connect by bearing between sieve end cap 8.Material inlet 5, coarse powder outlet 4, fine powder outlet are provided on outer housing
3, the process that fine powder outlet 3 enters next weighing and bagging as finished powder.
As Figure 2-3, turn the both ends of screen axis 2, specifically, turning screen axis 2 and motor output end junction and turning screen axis 2
It is respectively provided with that there are one seal assemblies with turning sieve end cap 8 junction.Specifically, the structure of seal assembly is as follows：Seal assembly includes
Two be sleeved on turn the lip packing on screen axis 2 11, for fix the sealing gland seat 9 of lip packing 11, be arranged on sealing gland seat 9 into
Gas nozzle 10, the suction nozzle 10 are connect with inlet duct, and inlet duct is air compressor machine, and the gas being passed through can be air or nitrogen
Gas, the suction nozzle 10 are located between two lip packing 11.
Specifically, sealing gland seat 9 is generally circular, be sleeved on outside lip packing 11, lip packing 11 include two lips and
The middle interconnecting piece of two lips is connected, the middle interconnecting piece is detachably secured on sealing gland seat 9, and sealing gland seat 9 can be fixed
On the non-rotary component of rotary screen, lip material is rubber or silica gel, and the material of middle interconnecting piece is stainless steel.
Preferably, two lips of each lip packing 11 and turn transition between screen axis 2 and coordinate.
It is furthermore preferred that the lip packing 11 and turning to be additionally provided with sealing shroud 12 between screen axis 2, the sealing shroud 12 is removable
It unloads to be fixed on and turn on screen axis 2, transition cooperation between the lip packing 11 and sealing shroud 12.The material of sealing shroud 12 can select
No. 45 steel with high hardness, it is more resistant.
In use, motor 1 is rotated with turn screen axis 2, sealing shroud 12, sealing shroud 12 rubs with lip packing 11, from air inlet
Mouth 10 is passed through high pressure gas, and high pressure gas enters the confined space that two lip packing 11, sealing shroud 12 and sealing gland seat 9 are formed
In, since the material of 11 two lips of lip packing is the flexible materials such as rubber or silica gel, high pressure gas can from lip with it is close
It is ejected between big envelope 12, forms gas wall, prevent dust from entering.Even if friction can lead to lip between lip packing 11 and sealing shroud 12
11 abrasion of shape sealing, nor affects on the formation of gas wall, so as to the elongate member replacement cycle, reduces frequency of maintenance.Sealing shroud 12
In the presence of protecting and turn screen axis 2, abrasion caused by preventing lip packing 11 directly to turning screen axis 2 avoids replacing and whole turns screen axis
2 bring it is of high cost the problem of, and when sealing shroud 12 is worn, it is only necessary to replace sealing shroud 12, reduce maintenance cost.Air inlet may be used also
To cool down to lip packing 11, because high-speed friction can generate heat, high temperature meeting between lip packing 11 and sealing shroud 12
The service life of lip packing 11 is reduced, therefore, hermetic seal can also play the role of extending the service life of lip packing 11.
