Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of ammonium nitrate cam shredder camshaft gas sealing mechanism.
Background technique
At present powder material in process of production, the leakage at the dynamic sealing point place of machinery not only causes a large amount of wastes, and the severe contamination surrounding environment.Especially modified ammonium nitrate-fuel oil explosive production line ammonium nitrate cam shredder seal arrangement adopts grease leak stopping mode, and because of this place's temperature height, grease liquefaction causes leakage rate big, has potential safety hazard.Simultaneously, the same industry does not also have settling mode preferably.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of a kind of modified ammonium nitrate-fuel oil explosive production line ammonium nitrate cam shredder gas sealing mechanism simple in structure, easy to operate, safe in utilization is provided.
For achieving the above object, the utility model adopts following technological scheme:
A kind of ammonium nitrate cam shredder camshaft gas sealing mechanism, it is characterized in that: constitute by nozzle, sealing seat, one end of nozzle is coaxial places sealing seat, and nozzle, sealing seat connect by bolton, and the external cylindrical surface of described sealing seat is provided with compressed air inlet port; Described nozzle places the external cylindrical surface of sealing seat to be provided with rectangle groove, and compressed air inlet port is communicated with rectangle groove; The rear end of the rectangle groove of nozzle is a taper type cap, on the taper type cap, be provided with vent, the taper type cap cooperates with the internal conical surface of sealing seat bottom, there is a conical cavity inside of sealing seat 1, this tapering is consistent with the tapering of the taper type cap of nozzle, reach the purpose of sealing, make to form the hermetic seal space between the conical surface of taper type cap and sealing seat bottom, camshaft passes through from the nozzle endoporus.
After adopting as above technological scheme, nozzle is installed on the sealing seat, whole again it is installed on the frame, the camshaft of rotation passes through from the nozzle endoporus.Form cavity between sealing seat and nozzle, pressurized air sprays from nozzle through cavity, forms air ring along the camshaft circumferencial direction, and sprays to sealed direction, stops powder material to leak, and reaches the purpose of sealing.
Preferably, described nozzle adopts stainless steel.Rectangle groove of processing on the circumferential section, its notch is over against the intake grill of sealing seat.
Preferably, described sealing seat adopts stainless steel.4 mounting holes are arranged on its big circumference, link to each other with frame by it.
Preferably, the vent on the described nozzle taper type cap is uniform 24.Pressurized air enters annular chamber from the suction port of sealing seat, and 24 apertures ejections from the taper type cap of nozzle form along the air ring of axle circumferencial direction again, stop powder material to leak, and reach the purpose of sealing.
The beneficial effect of a kind of ammonium nitrate cam of the utility model shredder camshaft gas sealing mechanism is, simple in structure, easy to operate, safe in utilization, intuitive measurement results, long service life.
