Description

Axis end sealing device of mixer
Technical field
The present invention relates to dry powder mortar mixing machine, relate in particular to axis end sealing device of mixer.
Background technique
Shaft end seal device is the critical component of dry powder mortar mixing machine, directly has influence on its usability.Mixing machine axle head in the past is to insert the graphite asbestos in the middle of the Seal cage on the sealing seat to seal, after using a period of time table, because the graphite asbestos do not have the resilience effect, after the graphite asbestos are pressed onto the dead point, final dry powder and mortar spills from spindle nose, if can not in time repair, may cause spindle nose to damage because of dry powder and mortar.
The purpose of this invention is to provide a kind of rational in infrastructure, good seal performance, long service life is enhanced productivity, and reduces the axis end sealing device of mixer of maintenance cost.
The present invention is achieved in that a kind of axis end sealing device of mixer; comprise bearing support; be provided with axle by bearing on the bearing support; the axle left surface is provided with positioning plate, and the bearing support both sides are respectively arranged with stifle and transparent cover, it is characterized in that: be provided with protecting jacket on the described axle; be provided with sealing seat on the protecting jacket; be provided with oil seal without framework and tetrafluoro packing in the groove between sealing seat and the protecting jacket, the tetrafluoro packing is fixed by gland, is provided with pressurized seal above the sealing seat.
The present invention is rational in infrastructure, has improved sealability, has prolonged working life, has improved manufacturing efficiency, has reduced maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure 1, bearing support, 2, bearing, 3, outside framework oil seal, 4, positioning plate, 5, stifle, 6, transparent cover, 7, gland, 8, pressurized seal, 9, sealing seat, 10, O type circle, 11, oil seal without framework, 12, the tetrafluoro packing, 13, axle, 14, protecting jacket.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
With reference to accompanying drawing; a kind of axis end sealing device of mixer; comprise bearing support 1, be provided with axle 13 by bearing 2 on the bearing support, the axle left surface is provided with positioning plate 4; the bearing support both sides are respectively arranged with stifle 5 and transparent cover 6; it is characterized in that: be provided with protecting jacket 14 on the described axle, be provided with sealing seat 9 on the protecting jacket, be provided with oil seal without framework 11 and tetrafluoro packing 12 in the groove between sealing seat and the protecting jacket; the tetrafluoro packing is fixing by gland 7, is provided with pressurized seal 8 above the sealing seat.During implementation, pressurized seal forms the first sealing by sealing seat and protecting jacket, and oil seal without framework forms the second sealing on the sealing seat, and the tetrafluoro packing forms three seals at the sealing seat seal chamber by gland.Thereby guarantee the sealing effect of axle head by the protection of three seals.
