The rotating shaft sealing structure comprises the sewage drainage suction tube shaft, a tank body, a seal cartridge and a gland; the tank body is internally provided with a seal cavity; the seal cartridge is mounted at the upper part of the seal cavity; an opening is formed in the top of the tank body, and is communicated with the seal cavity; the gland is mounted at the opening; the sewage drainage suction tube shaft penetrates through the gland, the seal cartridge and the tank body in sequence; a lower accommodating cavity is arranged at the bottom end of the seal cartridge, and a lower seal ring is arranged inside the lower accommodating cavity; the central part of the lower seal ring is tightly attached to the sewage drainage suction tube shaft; an upper accommodating cavity is arranged at the top end of the seal cartridge, and an upper seal ring and a graphite packing ring are arranged inside the upper accommodating cavity; the graphite packing ring is positioned below the upper seal ring; the top of the upper seal ring is tightly attached to the bottom of the gland; the central parts of the upper seal ring and the graphite packing ring are both tightly attached to the sewage drainage suction tube shaft.
Description
Technical field
The utility model relates to the technical field of pulp water filtrating equipment, particularly relates to a kind of pulp water circulating water strainer rotating shaft sealing structure.
Background technique
As everyone knows, pulp water circulating water strainer is a kind of pulp water filtrating equipment, is widely used in industrial production and manufacture field; And the pulp water circulating water strainer of prior art generally comprises tank body, filter element, backwash mechanism, electric control box, electric valve device and difference pressure control device; When use, when pulp water is entered after filter by import, through filter screen, enter water-purifying cavity after the filter outside filter screen through filter post inner chamber, solid particulate matter is isolated in filter screen inner side, along with filtrate is constantly filtered, filter cake progressive additive inside filter screen, resistance is increasing, before filter, after filter, pressure difference also increases gradually, in the time that pressure difference increases to default backwash pressure reduction, differential pressure controller sends electrically switchable grating signal, and main electric motor starting blowdown is inhaled and drawn tubular axis rotation; Blowdown inhale draw tubular axis adopt with between tank body together with skeleton shaft seal seal, long-play will cause shaft seal wearing and tearing, pulp water will leak outside along spindle nose, pulp water system pressure reduces; The defect of this pulp water circulating water strainer shaft sealing configuration is that blowdown inhales that to draw the sealing of tubular axis and tank body poor, and the pulp water phenomenon that leaks outside appears in long-play, has a strong impact on the normal operation of equipment.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of and improves blowdown and inhale and draw the pulp water circulating water strainer rotating shaft sealing structure of tubular axis sealing effect.
Pulp water circulating water strainer rotating shaft sealing structure of the present utility model, comprises that blowdown is inhaled to draw tubular axis, tank body, stuffing box gland and gland; In described tank body, be provided with Seal cage, described stuffing box gland is arranged on described Seal cage top, described tank body open top, and described opening communicates with Seal cage, described gland is arranged on described opening, and described blowdown is inhaled and drawn tubular axis successively through described gland, stuffing box gland and tank body, and described stuffing box gland bottom is provided with lower placed cavity, and being provided with lower seal in described lower placed cavity, the central position of described lower seal is adjacent to described blowdown suction and draws tubular axis; Described stuffing box gland top is provided with placed cavity, and seal ring and carbon packing ring on being provided with in placed cavity on described, described carbon packing ring is positioned at the below of described upper seal ring, the top of described upper seal ring is adjacent to the bottom of described gland, and the central position of described upper seal ring and carbon packing ring is all adjacent to described blowdown suction and draws tubular axis.
Pulp water circulating water strainer rotating shaft sealing structure of the present utility model, described gland is fixed on the top of described tank body by gland fixing bolt.
Pulp water circulating water strainer rotating shaft sealing structure of the present utility model, described upper seal ring and lower seal are " Y " RunddichtringO.
Pulp water circulating water strainer rotating shaft sealing structure of the present utility model, also comprise lower tightening cover, described lower tightening cover is positioned at Seal cage, and described lower tightening cover and stuffing box gland are installed together, the bottom of described lower seal is adjacent to the top of described lower tightening cover, and described blowdown is inhaled and drawn tubular axis through described lower tightening cover.
Compared with prior art the beneficial effects of the utility model are: by above-mentioned setting, can inhale the effect of drawing tubular axis and play secondary seal to blowdown by the upper seal ring and the carbon packing ring that increase, prevent that pulp water from overflowing from axle head, and blowdown is inhaled and is drawn tubular axis and in rotation process, can not scratch blowdown and inhale and draw tubular axis; Meanwhile, graphite plays lubricated effect in tubular axis rotary course is drawn in blowdown suction, compared with former sealing configuration, can not increase blowdown and inhale the resistance that draws tubular axis rotation; Therefore, inhale to draw tubular axis sealing and do not increase blowdown suction draw under the prerequisite of tubular axis rotational resistance in raising blowdown, the seal form of seal ring+carbon packing ring+lower seal in employing, can greatly improve blowdown and inhale the sealing effect that draws tubular axis.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, pulp water circulating water strainer rotating shaft sealing structure of the present utility model, comprises that blowdown is inhaled to draw tubular axis 1, tank body 2, stuffing box gland 3 and gland 4; In tank body, be provided with Seal cage, stuffing box gland is arranged on Seal cage top, tank body open top, and opening communicates with Seal cage, gland is arranged on opening, and blowdown is inhaled and drawn tubular axis successively through gland, stuffing box gland and tank body, and stuffing box gland bottom is provided with lower placed cavity, and in lower placed cavity, being provided with lower seal 5, the central position of lower seal is adjacent to blowdown suction and draws tubular axis; Stuffing box gland top is provided with placed cavity, and in upper placed cavity, be provided with seal ring 6 and carbon packing ring 7, carbon packing ring is positioned at the below of seal ring, and the top of upper seal ring is adjacent to the bottom of gland, and the central position of upper seal ring and carbon packing ring is all adjacent to blowdown suction and draws tubular axis; By above-mentioned setting, can inhale the effect of drawing tubular axis and play secondary seal to blowdown by the upper seal ring and the carbon packing ring that increase, prevent that pulp water from overflowing from axle head, and blowdown is inhaled and is drawn tubular axis and in rotation process, can not scratch blowdown and inhale and draw tubular axis; Meanwhile, graphite plays lubricated effect in tubular axis rotary course is drawn in blowdown suction, compared with former sealing configuration, can not increase blowdown and inhale the resistance that draws tubular axis rotation; Therefore, inhale to draw tubular axis sealing and do not increase blowdown suction draw under the prerequisite of tubular axis rotational resistance in raising blowdown, the seal form of seal ring+carbon packing ring+lower seal in employing, can greatly improve blowdown and inhale the sealing effect that draws tubular axis.
