Description
Technical field
The utility model relates to a kind of double-inlet and double-outlet steel ball coal mill, is specifically related to a kind of gear sealed air device, belongs to field of mechanical technique.
Background technology
Double-inlet and double-outlet steel ball coal mill is mainly used in grinding of power plant's coal dust, its work under bad environment.Big-small gear device, as the primary drive parts of double-inlet and double-outlet steel ball coal mill, must carry out efficiently, reliably sealing to it, once there be dust to enter, will cause wearing and tearing to large pinion, affect normally carrying out of equipment.At present, the sealing mainly equipment sealing of big-small gear device, namely carry out axis or radial seal to gear cover, sealing, under positive pressure system is run, effectively can not ensure the sealing of geared system.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, simple and practical gear sealed air device.
For solving this technical problem, the utility model provides a kind of gear sealed air device, comprise gear cover, connecting line, seal fan and base, described gear cover covers and form first achieve to gear on large pinion, base and grinding machine equipment connection, seal fan is arranged on base, and the air outlet of seal fan is connected to gear cover through connecting line and is full of sealing air in gear cover.
Flange joint is passed through with seal fan and gear cover respectively in described connecting line two ends, and junction is provided with sealing ring.
Beneficial effect: the utility model is provided with seal fan, during system works, passes into sealing air in gear cover, effectively prevent entering of dust, ensure that the operation that geared system is safe and reliable to there is structure simple, be easy to adjustment and safeguard, economizing on resources, be conducive to enhancing productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 gear cover, 2 connecting lines, 3 seal fans, 4 bases.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises gear cover 1, connecting line 2, seal fan 3 and base 4.
Described gear cover 1 covers on large pinion, to be used for airtight large pinion, forms first achieve to gear.
Described base 4 and grinding machine equipment connection, be used for supporting seal fan 3.
Described seal fan 3 is arranged on base 4, and its air outlet is connected to gear cover 1 through connecting line 2, in gear cover 1, be full of sealing air.
Flange joint is passed through with seal fan 3 and gear cover 1 respectively in described connecting line 2 two ends, and junction is provided with sealing ring.
Operation principle of the present utility model and the course of work:
Before system works, start seal fan 3, the sealing air entered from entrance is sent into gear cover 1 by outlet through connecting line 2 by seal fan 3 after filtering, and gear cover 1 is full of starting device after sealing air, owing to being full of sealing air in gear cover 1, effectively prevent entering of dust; After equipment shuts down, then close seal fan 3.
The utility model is provided with seal fan, during system works, in gear cover, passes into sealing air, effectively prevent entering of dust, ensure that the operation that geared system is safe and reliable to there is structure simple, be easy to adjustment and safeguard, economizing on resources, be conducive to enhancing productivity.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
