Environment pollutes, and adds the labor intensity of worker.
Utility model content
The technical problem that the utility model aims to solve the problem that is to provide a kind of chip type spring sealing structure for being used for translation sieve, piece
The spring sealed structure of formula extends the service life of equipment, improves site environment, reduce worker at translation screening machine inlet
Make fatigue resistance.
Adopt the following technical scheme that：
A kind of chip type spring sealing structure for being used for translation sieve, including funnel shaped lower cone, the upper surface of lower cone are consolidated
The annulus of rectangular section is connected to, the top of annulus is equipped with annular groove, sealed graphite packing, graphite packing are installed in annular groove
Contacted with the lower surface of first flange, first flange and the first connecting tube are affixed, and the first connecting tube passes through rubber with the second connecting tube
Glue flexible element connects, and the second connecting tube and second flange are affixed, and second flange is bolted with the 3rd flange, the bolt
Second flange is penetrated by the 3rd flange, the nut coordinated with bolt is located at the lower section of second flange, and the upper surface of first flange is set
Have with the corresponding positioning pin of bolt, elastic component is installed, the upper end of elastic component is sleeved on second flange between bolt and positioning pin
On the bolt of lower section, the lower end of elastic component is sleeved on positioning pin.
Using above-mentioned technical proposal the utility model compared with prior art, beneficial effect is：
After the abrasion of sealed graphite packing, compensated automatically by elastic component thrust, enhance sealing effect, it is several to reduce leakage
Rate, extends the service life of equipment, improves site environment, reduces fatigue resistance.
Further, the prioritization scheme of the utility model is：
The upper end of elastic component is sleeved on the bolt below nut, is equipped between the upper surface and nut lower surface of elastic component
Plain cushion.
Elastic component is spring.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Refering to attached drawing, the present embodiment includes lower cone 1, and lower cone 1 is funnel-shaped structure, the upper surface of lower cone 1
The annulus 2 of rectangular section is welded with, the top of annulus 2 is equipped with the annular groove 2-1 of rectangular cross-section, pacifies in annular groove 2-1
Sealed graphite packing 3 is filled, graphite packing 3 is contacted with the lower surface of first flange 4.First flange 4 is welded on the first connecting tube 12
The excircle of lower end, the first connecting tube 12 are connected with the second connecting tube 14 by elastomeric flex part 13, and second flange 8 is welded on
The excircle of two connecting tubes, 14 upper end, second flange 8 are connected with the 3rd flange 9 by bolt 10.Bolt 10 is worn by the 3rd flange 9
Enter second flange 8, the nut 11 coordinated with bolt 10 is located at the lower section of second flange 8, and the lower end of bolt 10 is less than nut 11
Lower surface, the upper surface of first flange 4 are welded with positioning pin 5 corresponding with bolt 10, axis and the bolt 10 of positioning pin 5
Axis overlaps, and spring 6 is installed between bolt 10 and positioning pin 5, and spring 6 is compression spring, and the upper end of spring 6 is sleeved on the lower section of nut 11
Bolt on, be equipped with plain cushion 7 between 11 lower surface of upper surface and nut of spring 6, the lower end of spring 6 is sleeved on positioning pin 5,
The lower face of spring 6 and the upper surface of first flange 4.
The present embodiment is at work：The lower port of lower cone 1 is welded with sieve nest, and the 3rd flange 9 is connected with feeding device, work
First flange 4 is set to be fitted close with lower cone 1 by sealed graphite packing 3 by the pressure of spring 6 when making, lower cone 1 is opposite
Move in a circle in first flange 4 in fixed pan, realize dynamic sealing.After sealed graphite packing 3 is worn, by pressing force of the spring
Automatic compensation, enhances sealing effect, reduces leakage probability.The present embodiment changes traditional flexible rubber connection sealing,
Chip type spring sealed connection is changed to, realizes that static and dynamic sealing is changed.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp scope, all equivalent structure changes made with the utility model specification and accompanying drawing content, is both contained in the utility model
Interest field within.
