Description
Technical field
The utility model bulk cargo chute connecting flange field of sealing technology, espespecially a kind of loose unpacked material chute flange double density sealed knot
Structure.
Background technology
The main top and the bottom made of steel plate splicing of existing country's loose unpacked material chute connecting flange, and in two methods
One layer of asbestos yarn is padded between orchid, is then bolted connection.This mode is fairly simple, but operates cumbersome and seal
Effect is bad, the reason for this is that：1）It needs to wear a bolt hole on asbestos yarn when installation bolt, troublesome in poeration and asbestos yarn is easy
Displacement；2）In processing and using asbestos friction material, tiny asbestos fibre can pollute empty gas and water or food, have strongly to human body
Stimulation and carcinogenesis；3）Since flange is deformed in blanking or welding, when material is relatively dry or moisture content is bigger,
It is poorly sealed to be easy to cause dust leakage or infiltration, cause environmental pollution.
Utility model content
The purpose of the utility model is to overcome prior art problems, provide a kind of durable and efficient loose unpacked material chute method
Orchid sealing.Its is simple in structure, easy to install and use, reduces dust leakage or infiltration in equipment running process, and then improve operation
Environment simultaneously lowers manual cleaning workload.
The technical solution of the utility model：A kind of loose unpacked material chute flange double sealing structure include chute I, chute II,
Bolt, upper flange, rubber weather strip, lower flange；The upper flange connects with the chute I；The lower flange and the chute
II connects；Several holes to match are had on the upper flange and the lower flange；The rubber weather strip is mounted on institute
It states between upper flange and lower flange；Several strip holes are provided on the rubber weather strip；The upper flange, the lower flange, institute
Rubber weather strip is stated to link together using bolt, nut；The both sides of the strip hole of the rubber weather strip have been symmetrically distributed
Two pairs of seal convexities, seal convexity I, seal convexity II；The seal convexity I, seal convexity II run through the rubber weather strip.
Further, the size of the strip hole is more than the size in the hole.
Further, the height of the seal convexity II is more than the height of the seal convexity I.
Further, the size in the hole is more than the outer diameter of the bolt.
Further, the rubber seal strip adoption flame retardant rubber makes.
The beneficial effects of the utility model：（1）Strip hole, spiral shell easy to use are set on the rubber weather strip of the utility model
Bolt nut is attached fastening to upper lower flange, and installation effectiveness is high；It is prevented simultaneously there are the rubber of one fixed width between strip hole
For rubber weather strip in the shift of installation, installation effect is good；（2）Two pairs of height are set not on the rubber weather strip of the utility model
Same seal convexity, it is first convex by a pair of high sealing in rubber weather strip upper surface when gradually locking the bolt on upper lower flange
Rise and II contacted with flange working face, then the low seal convexity I of rubber weather strip upper surface a pair also slowly with flange working face
Contact, until compressing completely, the double containment connection in realization between lower flange, using this double-layer seal connection structure sealing effect
Significantly；（3）The rubber seal strip adoption flame retardant rubber of the utility model, can effectively prevent the sprawling of unexpected burning things which may cause a fire disaster.
Description of the drawings
Fig. 1 is that the utility model implements structural schematic diagram；Fig. 2 is that the utility model implements partial sectional view.
Specific implementation mode
As shown in the figure：A kind of loose unpacked material chute flange double sealing structure includes chute I 1, chute II 9, bolt 2, upper method
Orchid 3, rubber weather strip 5, lower flange 7；The upper flange 3 connects with the chute I 1；The lower flange 7 and the chute II 9
Connect；Several holes 8 to match are had on the upper flange 3 and the lower flange 7；The rubber weather strip 5 is mounted on
Between the upper flange 3 and lower flange 7；Several strip holes 6 are provided on the rubber weather strip 5；The upper flange 3, it is described under
Flange 7, the rubber weather strip 5 are linked together using bolt 2, nut；The both sides of the strip hole 6 of the rubber weather strip 5
It has been symmetrically distributed two pairs of seal convexities, seal convexity I 4, seal convexity II 10；The seal convexity I 4, seal convexity II 10
Through the rubber weather strip 5；The size of the strip hole 6 is more than the size in the hole 8；The height of the seal convexity II 10
More than the height of the seal convexity I 4；The size in the hole 8 is more than the outer diameter of the bolt 2；The rubber weather strip 5
It is made of flame retardant rubber.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the protection of the utility model claims book determination
In range.
