Description
Technical field
The utility model relates to axle sealing structure technical field, specifically a kind of Novel conditioner sealing structure of shaft end.
Background technique
The shaft end seal of existing quality-adjusting device generally adopts single gland sealed structural type, and such structure causes when doing expanded pellet diet, can leak out slip from spindle nose position, two ends.The reason of leaking is caused to be due to a certain amount of water and steam will be added when doing expanded pellet diet, operationally, certain pressure is had in quality-adjusting device cylindrical shell, such material will leak from spindle nose filler position, two ends along with water and steam, of long duration, can shorten on the one hand the working life of bearing, what also affect in manufacturing shop on the other hand is clean and tidy, and can cause the waste of raw material.
Summary of the invention
The utility model provides a kind of Novel conditioner sealing structure of shaft end, the sealing configuration form combined with packing seal by labyrinth sealing, when this sealing configuration is used in and does expanded pellet diet, first can be stopped the leakage of steam by labyrinth structure, and then stop the leakage of material by packing seal structure.By labyrinth seal and gland sealed double action, the overall sealing effect improving quality-adjusting device of energy, fundamentally solves the leakage problem of quality-adjusting device.
For solving the problems of the technologies described above, the embodiment of the present application provides a kind of Novel conditioner sealing structure of shaft end, comprise main shaft, main shaft is installed with wear-resistant sleeve, axle head body is installed with stuffing box packing case, the interior side contacts place of wear-resistant sleeve and stuffing box packing case is provided with the tongue and groove cooperatively interacted and forms labyrinth seal district, and between wear-resistant sleeve and stuffing box packing case, outer end also has one section of packing cavity, in packing cavity, be plugged with filler form packing seal district, bearing is arranged on the outer end away from packing seal district.
As the preferred embodiment of this programme, described tongue and groove is the rectangle groove cooperatively interacted.
As the preferred embodiment of this programme, described wear-resistant sleeve one end is connected on main shaft, and the other end is fixed on main shaft by the screw be embedded in wear-resistant sleeve.
The one or more technological schemes provided in the embodiment of the present application, at least have following technique effect or advantage:
The sealing configuration form combined with packing seal by labyrinth sealing, when this sealing configuration is used in and does expanded pellet diet, first can stop the leakage of steam by labyrinth structure, and then stops the leakage of material by packing seal structure.By labyrinth seal and gland sealed double action, the overall sealing effect improving quality-adjusting device of energy, fundamentally solves the leakage problem of quality-adjusting device.
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.
Fig. 1 is the overall structure schematic diagram of the application.
In figure, 1, main shaft, 2, wear-resistant sleeve, 3, stuffing box packing case, 4, labyrinth seal district, 5, packing cavity, 6, packing seal district, 7, bearing, 8, screw.
Embodiment
The utility model provides a kind of Novel conditioner sealing structure of shaft end, the sealing configuration form combined with packing seal by labyrinth sealing, when this sealing configuration is used in and does expanded pellet diet, first can be stopped the leakage of steam by labyrinth structure, and then stop the leakage of material by packing seal structure.By labyrinth seal and gland sealed double action, the overall sealing effect improving quality-adjusting device of energy, fundamentally solves the leakage problem of quality-adjusting device.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete mode of execution, technique scheme is described in detail.
Embodiment one:
With reference to Fig. 1, for solving the problems of the technologies described above, the embodiment of the present application provides a kind of Novel conditioner sealing structure of shaft end, comprise main shaft 1, main shaft 1 is installed with wear-resistant sleeve 2, axle head body is installed with stuffing box packing case 3, wear-resistant sleeve 2 is provided with the interior side contacts place of stuffing box packing case 3 tongue and groove cooperatively interacted and forms labyrinth seal district 4, between wear-resistant sleeve 2 and stuffing box packing case 3, outer end also has one section of packing cavity 5, in packing cavity 5, be plugged with filler form packing seal district 6, bearing 7 is arranged on the outer end away from packing seal district 6, certain spacing is left between seal area and bearing 7, bearing 7 can be protected like this, again can be for convenience detach, to change filler, comprehensive above analysis, this sealing configuration effectively can improve the situation of quality-adjusting device leaked substance, and the working life of bearing can also be improved, the cost of production of client is reduced.
Wherein, in the present embodiment, described tongue and groove is the rectangle groove cooperatively interacted.
Wherein, in the present embodiment, described wear-resistant sleeve 2 one end is connected on main shaft 1, and the other end is fixed on main shaft 1 by the screw 8 be embedded in wear-resistant sleeve 2.
During work, wear-resistant sleeve 2 rotates together with main shaft 1, and filling sealing tank 3 geo-stationary, have very little gap between wear-resistant sleeve 2 and filling sealing tank 3, just define one section of labyrinth structure like this between wear-resistant sleeve 2 and filling sealing tank 3; One section of packing cavity is also had between filling sealing tank 3 and wear-resistant sleeve 2, filler is plugged with in packing cavity, this section is packing seal district, material starts first by labyrinth seal district most, and during by labyrinth structure district, labyrinth structure can stop the effusion of steam, and then by packing seal district, packing seal district can stop the leakage of material, has had this two sections of seal areas, and material is just difficult to again from the internal leakage of quality-adjusting device cylindrical shell out.
Technological scheme in above-mentioned the embodiment of the present application, at least has following technique effect or advantage:
The sealing configuration form combined with packing seal by labyrinth sealing, when this sealing configuration is used in and does expanded pellet diet, first can stop the leakage of steam by labyrinth structure, and then stops the leakage of material by packing seal structure.By labyrinth seal and gland sealed double action, the overall sealing effect improving quality-adjusting device of energy, fundamentally solves the leakage problem of quality-adjusting device.
Although described preferred embodiment of the present utility model, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the utility model scope.
