Description
Technical field
The utility model relates to mechanical structure field, is specifically related to the sealing mechanical structure in the fields such as biological organic fertilizer, food machinery, bio-pharmaceuticals.
Background technique
It is the important indicator evaluating mechanical quality at industry oil seepages such as biological organic fertilizer manufacture, food machinery, water treatments; Seepage can cause very large threat to machine security reliable operation, and at present, the sealing configuration generally adopted mainly contains the contact such as seal ring, piston ring sealing and the non-contact seals such as labyrinth seal, centrifugal seal; Independent employing above-mentioned any one seal form is all difficult to realize leak free effect, and this all can bring loss to user.
Model utility content
It is simple that the technical problems to be solved in the utility model is to provide structure, uses, easy for installation, simple to operate, and good sealing effect, high lubricating effect, cost is low, applied widely, long service life, has the sealing mechanical structure of safe and reliable effect.
For solving the problem, the utility model adopts following technological scheme.
Sealing mechanical structure, comprise mechanical hull, sealing cover and main shaft, and the labyrinth seal structure be arranged on mechanical hull, and the disc be arranged on mechanical hull, and the quad seal structure be arranged on mechanical hull, and the seal ring be arranged on main shaft, be provided with for the fixed block supported and supply main shaft to rotate in described mechanical hull, described main shaft is also provided with the first seal ring and the second seal ring, a part for described main shaft is arranged in mechanical hull, described fixed block, labyrinth seal structure, disc and quad seal structure are arranged in mechanical hull successively, and offset with main shaft, one of described second seal ring is embedded in mechanical hull, and offset with the first seal ring be arranged in mechanical hull, described seal ring and the second seal ring side offset, the side of described sealing cover and seal ring is tightly connected, described sealing cover is provided with screw, described first seal ring, to be mutually tightly connected between the second seal ring and seal ring.
Further, described sealing cover is fixedly connected with mechanical hull by screw.
Further, described main shaft is hollow shaft.
The beneficial effect of the utility model sealing mechanical structure is: during use, working lubrication oil is directly or indirectly ejected on disc, by main shaft is arranged to hollow shaft, add centrifugal force when it rotates, thus working lubrication oil is passed through between mechanical hull and running shaft, by set labyrinth seal structure, quad seal structure and the first seal ring, make working lubrication oil be in the position needing lubrication always, avoid leakage and the outflow of lubricant oil, by the second set seal ring, seal ring and sealing cover, and the screw be arranged on sealing cover, make the sealing configuration that is arranged in mechanical hull detachable, avoiding that a place sealing configuration destroys will total situation about changing, thus it also avoid the waste of resource.Its structure is simple, uses, easy for installation, simple to operate, and good sealing effect, high lubricating effect, cost is low, applied widely, long service life, has safe and reliable effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
