Description
Technical field
The utility model relates to ball mill technical field, particularly relates to a kind of feed inlet sealing device of ball mill.
Background technology
Ball mill is rotary operation, and inlet device is fixed, and a dynamic and static object is connected, and leakage problems must be considered in centre, and therefore sealing is key.Ball mill inlet seal is general all less desirable, and the sealing especially for the dry ball being provided with pulverizer equipment before wet ball mill or import is just a problem very much, often there will be spillage or leaks grey phenomenon.Current ball mill inlet seal adopts soft packing seal (packing_seal) mostly, and this sealing is short for service life, needs often to change, and after using a period of time, leakage rate increase is difficult to meet seal request.
Summary of the invention
The utility model is intended to solve the deficiencies in the prior art, and provides a kind of feed inlet sealing device of ball mill.
The utility model for achieving the above object, by the following technical solutions: a kind of feed inlet sealing device of ball mill, comprise feed pipe, pan feeding lining, described pan feeding lining is positioned at described feed pipe both sides, it is characterized in that, mechanical seal is provided with between described pan feeding lining and feed pipe, described mechanical seal comprises trim ring, sealing ring, rubber blanket, described rubber blanket is L-type rubber blanket, described sealing ring is positioned at inside described rubber blanket, described trim ring covers on described sealing ring and described rubber blanket, described trim ring is fixedly connected with described rubber blanket by bolt, described sealing ring is three flap seal rings, described sealing ring is spliced by three pieces of unidirectional angle circular arc blocks.
Described pan feeding lining also has slurry leakage hole.
The beneficial effects of the utility model are: the utility model is provided with L-type rubber blanket on sealing device, trim ring on sealing ring side is arranged again, and sealing ring adopts the hard packing of three flap seal rings to seal, be different from traditional soft packing seal, sealing effectiveness is more reliable, longer service life, has saved production cost greatly.
