Description
Technical field
The utility model relates to a kind of sealing structure, in particular to a kind of lime preheater push rod seal structure.
Background technique
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.
Summary of the invention
The shortcomings that in order to overcome the prior art, the utility model provide a kind of lime preheater push rod seal structure.It is tied
Structure is simple, structurally reasonable, and sealing effect is good.
The technical solution adopted by the utility model to solve its technical problems is that: there is cover board long hole on push rod box cover,
Ground way seal receptacle at cover board long hole outside push rod box cover is embedded with slideway on the inner wall of the centre bore of slideway seal receptacle
Slot, the lower end of the slide groove are communicated with the cover board long hole, so as in slide groove dust and sundries flow out automatically, it is described
Middle slideway slot internal clearance be combined with movable sealing seat, movable sealing seat can be translatable in vertical plane in slide groove, activity
The inner hole of seal receptacle is slidably matched by sealing shroud and push rod, push rod and the cover board hole, slideway seal receptacle centre bore between
Gap cooperation.
The utility model have the advantage that 1), seal assembly production into two, convenient for not dismantling the components such as push rod
In the case of replace sealing;2), circle is made in the slideway in slideway seal receptacle and movable sealing seat slide, is conducive to move freely,
Sealing function is played in sliding;3), slideway seal receptacle inner slide inner edge lower aperture flows automatically conducive to dust in slideway and sundries
Out;4), sealing shroud plays sealing function in pushrod movement loaded on cooperating in movable sealing seat with push rod.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the utility model main view;
Fig. 2 is the utility model left view;
Fig. 3 is the utility model rearview;
Fig. 4 is the A-A cross-sectional view in the utility model Fig. 1.
Specific embodiment
As Figure 1-Figure 4, there are cover board long hole 16, the cover board long hole 16 outside push rod box cover 1 on 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 long hole 16 communicates, so as in slide groove 20 dust and sundries flow out automatically, the slide groove internal clearance is matched
Conjunction has movable sealing seat, and movable sealing seat can be translatable in vertical plane in slide groove 20, and the inner hole of movable sealing seat passes through
Sealing shroud is slidably matched with push rod 12, the centre bore clearance fit of push rod 12 and the cover board long 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.
