due to the utilization of technique scheme, the present invention compared with prior art has following advantages: a kind of stirring shaft seal arrangement of the present invention, by arranging double-deck lining between through hole and stirring shaft, first lining of inner side is attached on stirring shaft and seals, second lining and the hold-down mechanism in outside are used for preventing the first lining in the vertical direction to be subjected to displacement, and serve good seal action.Apparatus of the present invention structure is simple, and it is convenient to change, good sealing effect.
Accompanying drawing explanation
accompanying drawing 1 is apparatus of the present invention sectional views vertically.
wherein: 1, top cover; 2, through hole; 3, stirring shaft; 4, the first lining; 5, the second lining; 6, compressing member; 7, fixed block; 8, the first seal ring; 9, dust-proof cover; 10, the second seal ring.
Embodiment
below in conjunction with accompanying drawing, technological scheme of the present invention is further elaborated.
shown in Figure 1, above-mentioned a kind of stirring shaft seal arrangement, is located on the top cover 1 of blend tank.This top cover 1 offers the through hole 2 passed for being stirred axle 3, what this stirring shaft 3 rotated around its direction of axis line is located in this blend tank.Sealing device is for sealing the gap between this through hole 2 and this stirring shaft 3.
above-mentioned seal arrangement comprises for filling out the lining group of establishing above-mentioned gap, this lining group comprise be located on perimembranous outside stirring shaft 3 the first lining 4, be arranged in outside this first lining 4 between perimembranous and this through hole 2 hole wall and part be coated on the second lining 5, second lining 5 of this first lining 4 lower end also for preventing the first lining 4 to be subjected to displacement in the rotation process of stirring shaft 3 downwards.The inner side perimembranous of this first lining 4 is attached on this stirring shaft 3, gap distribution between the inner side perimembranous of this second lining 5 and this stirring shaft 3.In the present embodiment, ringwise, in order to make this first lining 4 can be fitted in play better sealing effect on stirring shaft 3 more closely, this first lining 4 is provided with the fracture of cutting sth. askew to this first lining 4.By arranging the first lining 4 and the second lining 5, when after the wearing and tearing of lining group, only need change the first inner lining 4, significantly saving production and processing cost.Sealing device also comprise be located on this top cover 1 for compressing this first lining 4 with the hold-down mechanism preventing it from moving up.
in the present embodiment, above-mentioned hold-down mechanism comprise be located on top cover 1 and be stirred compressing member 6 that axle 3 passes, for this compressing member 6 being fixed on the fixed block 7 on this top cover 1, this fixed block 7 is bolt and pad.Gap distribution between this compressing member 6 and this stirring shaft 3.The upper surface of above-mentioned first lining 4 is a little more than the upper surface of above-mentioned second lining 5, and the lower surface of this compressing member 6 is sticked on the upper surface of this first lining 4, is upwards subjected to displacement in the rotation process of stirring shaft 3 for preventing the first lining 4.In order to obtain better sealing effect, between the hole wall of this through hole 2 and the outside perimembranous of this second lining 4, be provided with the first seal ring 8 for sealing.
