Abstract
The utility model relates to a crucible rotation magnetic sealing device which comprises a shell, dustproof oil seal rings, a magnetic seal ring, a bearing washer, a bearing, an end cover and a rotary shaft. The device provided by the utility model has the beneficial effects that the magnetic seal ring is arranged inside the upper part of the shell, and the magnetic seal ring is matched with the shell to prevent cooling water from leaking caused by lip abrasion of a frame oil seal; the dustproof oil seal ring is respectively arranged inside the upper end of the shell, and the dustproof oil seal ring is arranged between the shell and the rotary shaft; the dustproof oil seal ring at the lower end is arranged inside the end cover and between the end cover and the rotary shaft to prevent dust at the port from entering the shell so as to reduce abrasion, so that the service life of the crucible rotation magnetic sealing device is longer.
Description
Technical field
The utility model relates to a kind of crucible rotation magnetic sealing device, especially relates to the crucible rotation magnetic sealing device in a kind of single crystal growing furnace field.
Background technology
Single crystal growing furnace loads after dissolving in the thermal field that silicon material is placed on furnace chamber and obtains through refining crystal with quartz crucible, in order to save the shove charge time, after usually need to silicon material being installed outside furnace chamber, then crucible is put into the crucible that furnace chamber molten charge is more more needs so.Nowadays most crucible rotation magnetic sealing device is owing to adopting outside framework oil seal to carry out dynamic seal to water coolant, once the wearing and tearing of the lip limit of outside framework oil seal very easily cause water coolant to be revealed.
Utility model content
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of crucible rotation magnetic sealing device of good sealing effect is provided.
A kind of crucible rotation magnetic sealing device comprises housing, dust laying oil seal, magnetic seal circle, bearing washer, bearing, end cap and turning axle, in housing, be provided with turning axle, housing lower end is connected with end cap by bolt, inner side, housing upper end is respectively provided with a dust laying oil seal and this dust laying oil seal is located between housing and turning axle, end cap inner side is located in the dust laying oil seal of lower end and this dust laying oil seal is located between end cap and turning axle, housing upper inner is provided with magnetic seal circle, inner side, housing middle part is provided with bearing washer and this bearing washer is located between housing and turning axle, inside housing, be provided with bearing and this bearing between turning axle and housing.
Preferably, top and the bottom of described housing inner side are respectively provided with a bearing.
Preferably, the bearing of described housing inside upper part is in magnetic seal circle below.
The beneficial effects of the utility model are: housing upper inner is provided with magnetic seal circle, adopt magnetic seal circle to coordinate with housing, prevent because wear and tear in the lip limit of outside framework oil seal, and cause cooling water leakage; Inner side, housing upper end is respectively provided with a dust laying oil seal and this dust laying oil seal is located between housing and turning axle, end cap inner side is located in the dust laying oil seal of lower end and this dust laying oil seal is located between end cap and turning axle, the dust that prevents port enters in housing, reduce wear phenomenon, made the longer service life of crucible rotation magnetic sealing device.
