Abstract
The utility model discloses a stirring bearing device for a glass reaction kettle. The device comprises a glass sleeve fixedly arranged on a stirring shaft in a sleeving manner, wherein a locking nut connected with an opening of the glass reaction kettle, a stirring shaft bearing block, a movable sealing ring, a lower bearing block, an upper bearing block, a bearing in the upper bearing block, a static sealing ring and a locking sleeve are arranged on the outer peripheral surface of the glass sleeve in a sleeving manner from bottom to top; the locking nut, the stirring shaft bearing block, the movable sealing ring, the lower bearing block, the upper bearing block and the bearing in the upper bearing block are in movable fit with the glass sleeve; the static sealing ring and the locking sleeve are in a static fit with the glass sleeve. The stirring bearing device has the advantages that the locking nut, the stirring shaft bearing block, the movable sealing ring, the lower bearing block and the upper bearing block are in movable fit with the glass sleeve after the glass sleeve is statically sealed together with the stirring shaft wrapped with a tetrafluoroethylene layer, so that the problem of scrap falling of the tetrafluoroethylene layer is solved on the premise of ensuring sealing, and meanwhile, the service life of the stirring shaft is prolonged.
Description
Technical field
The utility model relates to bearing, especially relates to the shaft bearing apparatus for glass reaction still.
Background technology
The conventional stirring bearing for glass reaction still, the one, adopt the form of bearing location and oil sealing sealing, shortcoming be oil sealing and bearing portion higher to the required precision of axle, can not adopt outer cladding tetrafluoroethene layer form, be easily corroded; The 2nd, adopt the form of mechanical seal, owing to there is no positioner, so can cause the friction between shaft and tetrafluoroethene layer, generation tetrafluoroethene layer chip and pollute reaction mass.
Summary of the invention
The utility model object is to provide a kind of shaft bearing apparatus for glass reaction still.
For achieving the above object, the utility model can be taked following technical proposals:
Shaft bearing apparatus for glass reaction still described in the utility model, comprise that fixed cover is loaded on the glass bushing on shaft, described glass bushing outer peripheral face is set with from bottom to top: for the locking nut, shaft bearing, dynamic seal ring, step, the top chock that are connected with glass reaction still mouth with put bearing, static sealing ring, lock sleeve in the inner; Described locking nut, shaft bearing, dynamic seal ring, step, top chock and put bearing in the inner and glass bushing between the moving suit that coordinates; Stationary fit suit between described static sealing ring, lock sleeve and glass bushing.
The utility model advantage is to adopt carries out described glass bushing and the shaft that is coated with tetrafluoroethene layer after static sealing, then by glass bushing and described locking nut, shaft bearing, dynamic seal ring, step, top chock with put the moving suit that coordinates between bearing in the inner, therefore, guaranteeing that under sealing prerequisite, having solved tetrafluoroethene layer falls bits problem, has extended the service life of shaft simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, shaft bearing apparatus for glass reaction still described in the utility model, comprise that fixed cover is loaded on the glass bushing 2 on shaft 1, described glass bushing 2 outer peripheral faces are set with from bottom to top: for the locking nut 4, shaft bearing 5, dynamic seal ring 6, step 7, the top chock 8 that are connected with glass reaction still mouth 3 with put bearing, static sealing ring 9, lock sleeve 10 in the inner; Described locking nut 4, shaft bearing 5, dynamic seal ring 6, step 7, top chock 8 and put bearing in the inner and glass bushing 2 between the moving suit that coordinates; Stationary fit suit between described static sealing ring 9, lock sleeve 10 and glass bushing 2.
