Abstract
The utility model discloses a novel cold quick -witted transmission shaft of combing is sealed device, including transmission shaft, the cold casing body of combing, be connected with the movive seal board on the transmission shaft, be connected with the static seal board on the cold casing body of combing, the movive seal board passes through the meshing of primary and secondary groove with the static seal board, be equipped with the filter screen of half parcel movive seal board, static seal board on the cold quick -witted shells inner wall that combs, have one set of sealing ring of establishing outside the transmission shaft in the design of corresponding transmission shaft department on the filter screen. The utility model discloses effectively block the passageway of comb cold built -in, outer gas, play good sealed effect, can stop thin granule to the wearing and tearing of preventing thin granule to get into sealing device and causing simultaneously also can not the polluted environment.
Description
Technical field
This utility model is related to a kind of field of cement production equipment and in particular to a kind of new grate-cooler drive shaft seal fills
Put.
Background technology
Cement in grate-cooler is also easy to produce larger dust, and in order to ensure preferable working environment, sealing and dustproof is very heavy
Will, therefore the two ends of line shaft, power transmission shaft must seal.The sealing of the line shaft only rotating is relatively easy to, and right
It is relative difficulty in the power transmission shaft reciprocatingly moving.At present, slide type is adopted to seal between the drive shaft of grate-cooler and housing
Device, including sealing plate, regulation ring, seal box etc., also have using packing gland formula sealing.Due to existing inside and outside cooling machine air chamber
Certain blast pressure reduction, the fine grained in air compartment can cause the abrasion of sealing device, cause grate-cooler with high-pressure blast to outward leakage
All multiple faults frequent, not only impact equipment cause operate, also can cause environmental pollution.
Content of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of new grate-cooler power transmission shaft
Sealing device.
The technical solution adopted in the utility model:New grate-cooler sealed device for drive-shaft, including power transmission shaft, grate-cooler
Housing, it is characterised in that being connected with dynamic sealing plate on power transmission shaft, is connected with static seal plate, dynamic sealing on grate-cooler housing
Plate is engaged by mother-son groove with static seal plate；Half parcel dynamic sealing plate, the mistake of static seal plate are provided with grate-cooler inner walls
Filter screen, drainage screen is designed with one at corresponding power transmission shaft and is set in the sealing ring outside power transmission shaft.
Compared to existing technologies, advantage of the present utility model：1st, pass through using mother-son groove engagement, effectively block grate-cooler
The passage of inside and outside gas, plays good sealing effectiveness；2nd, drainage screen is set, even if under dynamic sealing plate, static seal plate deform
Wind direction outward leakage, it is also possible to stop fine grained, in case the abrasion that fine grained enters sealing device and causes, also will not pollute simultaneously
Environment.
Brief description
Fig. 1 is structural representation of the present utility model
Wherein, 1, power transmission shaft, 2, grate-cooler housing, 3, static seal plate, 4, dynamic sealing plate, 5, sprocket wheel, 6, drainage screen, 7, close
Seal ring.
Specific embodiment
In conjunction with accompanying drawing, this utility model is further elaborated.
As shown in figure 1, new grate-cooler sealed device for drive-shaft, including power transmission shaft 1, grate-cooler housing 2, in power transmission shaft 1
On be connected with dynamic sealing plate 4, static seal plate 3 is connected with grate-cooler housing 2, dynamic sealing plate 4 passes through primary and secondary with static seal plate 3
Groove engages；Wrap up the drainage screen 6 of dynamic sealing plate 4, static seal plate 3 in grate-cooler housing 2 inwall upper half, drainage screen 6 is corresponding to
It is designed with one at power transmission shaft 1 and be set in the sealing ring 7 outside power transmission shaft 1.
Power transmission shaft 1 is fixedly connected with sprocket wheel 5, drives power transmission shaft 1 to rotate using driving means, transmission followed by dynamic sealing plate 4
Axle rotates, and static seal plate maintains static, and is engaged by the mother-son groove more than 1 between dynamic sealing plate and static seal plate,
Meanwhile, it is slidably matched between the sealing ring 7 on power transmission shaft 1 and drainage screen 6, thus playing good sealing effectiveness.
