Abstract
The present invention relates to a kind of lime preheater push rod seal structures.There is cover board slot hole on push rod box cover, ground way seal receptacle at cover board slot hole outside push rod box cover, slide groove is embedded on the inner wall of the centre bore of slideway seal receptacle, the lower end of the slide groove is communicated with the cover board slot hole, so as in slide groove dust and sundries flow out automatically, the middle slideway slot internal clearance is combined with movable sealing seat, movable sealing seat can be translatable in vertical plane in slide groove, the endoporus of movable sealing seat is slidably matched by sealing shroud and push rod, the centre bore clearance fit of push rod and the cover board hole, slideway seal receptacle.
Description
Technical field
The present invention relates to a kind of sealing structure, more particularly to a kind of lime preheater push rod seal structure.
Background technology
After a period of use, often there is situation of leaking out at preheater push rod, it is certain to see that sealing structure exists from original design
Problem, sealing device and push rod other strength when push rod is run, resistance is big, and push rod and sealing part abrasion are fast, and long-time service causes to wear
It is the main reason for leaking out.
Invention content
The shortcomings that in order to overcome the prior art, the present invention provide a kind of lime preheater push rod seal structure.The letter of its structure
Single, reasonable for structure, sealing effect is good.
The technical scheme adopted by the invention to solve the technical problem is that：There are cover board slot hole, push rod on push rod box cover
Ground way seal receptacle at cover board slot hole outside box cover is embedded with slide groove, institute on the inner wall of the centre bore of slideway seal receptacle
The lower end for stating slide groove is communicated with the cover board slot hole, so as in slide groove dust and sundries flow out automatically, in described
Slide groove internal clearance is combined with movable sealing seat, and movable sealing seat can be translatable in vertical plane in slide groove, movable sealing
The endoporus of seat is slidably matched by sealing shroud and push rod, and the center interporal lacuna of push rod and the cover board hole, slideway seal receptacle is matched
It closes.
The present invention has following advantages：1), seal assembly makes into two, convenient for not dismantling the parts situation such as push rod
Lower replacement sealing；2), circle is made in the slideway in slideway seal receptacle and movable sealing seat slide, is conducive to free activity, sliding
In play sealing function；3), slideway seal receptacle inner slide inner edge lower aperture flows out automatically conducive to dust in slideway and sundries；
4), sealing shroud plays sealing function loaded on coordinating with push rod in movable sealing seat in pushrod movement.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is front view of the present invention；
Fig. 2 is left view of the present invention；
Fig. 3 is rearview of the present invention；
Fig. 4 is the A-A sectional views in Fig. 1 of the present invention.
Specific implementation mode
As Figure 1-Figure 4, there is cover board slot hole 16 on push rod box cover 1, the cover board slot hole 16 outside push rod box cover 1
Locate ground way seal receptacle, be embedded with slide groove 20 on the inner wall of the centre bore of slideway seal receptacle, the lower end of the slide groove 20 with
The cover board slot hole 16 communicates, so as in slide groove 20 dust and sundries flow out automatically, the middle slideway slot internal clearance
It is combined with movable sealing seat, movable sealing seat can be translatable in vertical plane in slide groove 20, and the endoporus of movable sealing seat is logical
It crosses sealing shroud to be slidably matched with push rod 12, the centre bore clearance fit of push rod 12 and the cover board hole 16, slideway seal receptacle.
The slideway seal receptacle includes left and right slideway seal receptacle 3,9, left and right slideway seal receptacle 3,9 symmetrical configurations.Easily
Processing, assembly.
The movable sealing seat includes left and right movable sealing seat 6,13, left and right movable sealing seat 6,13 symmetrical configurations.
Easy processing, assembly.
The sealing shroud includes left and right sealing shroud 18,19, left and right sealing shroud 18,19 symmetrical configurations.Easy processing, dress
Match.
