Abstract
The utility model relates to a high speed shaft sealer for a vertical mixer. The utility model comprises a seal head, a plumbaginous stationary seal ring, a stationary seat, a plurality of springs, a shell and a cover board. The space between a rotating shaft and the seal head is oil-tightened. The lower surface of the seal head which matches with the upper surface of the plumbaginous stationary seal ring is a sealing face. The plumbaginous stationary seal ring is positioned in a stationary seal ring groove of the stationary seat. A plurality of springs are arranged under the stationary seat to support the stationary seat. The cover board is a convex and round table. A sealing ring which is positioned on the inside wall of the stationary seat is chucked tightly on the circumference of a small-diameter part of the cover board. A plurality of step screw holes are arranged on the cover board to fix the cover board on the shell and fix the shell on a stander. A sealing ring is positioned between the shell and the stander. No oil leakage is produced in long-term operation with the high speed shaft sealer.
Description
The utility model relates to dynamic seal.
The reducing gear of vertical mixer all adopts the multi-stage gear gearbox.Former design seal form adopts lip type oil seal, the seal ring that it is oblique V font that lip seal adopts 2 sections is formed by stacking as shown in Figure 1, though this lip seal has spring axially afterburning, but still the gear-box leakage of oil of stirrer takes place easily, especially under the situation that lip seal weares and teares to some extent.
The purpose of this utility model provides a kind of vertical mixer high speed shaft Sealing, and it can avoid the problem of gear-box leakage of oil, prolongs operating life.
The technical solution of the utility model is as follows:
A kind of vertical mixer high speed shaft Sealing, it is made up of rotating ring, graphite stationary ring, stationary seat, spring, housing and cover plate, rotating ring is cylindric annulus, on the madial wall of rotating ring seal groove is arranged, place seal ring in the groove, seal ring makes between rotating shaft and the rotating ring and reaches oil seal, and rotating ring is rotated with rotating shaft, the lower end surface of rotating ring is an end face seal face, be complementary with the upper-end surface of graphite stationary ring, graphite stationary ring also is cylindric annulus, and the upper-end surface is an end face seal face, and graphite stationary ring adopts interference fit in the stationary ring groove of stationary seat.Stationary seat is circular, and there is the stationary ring groove upper-end surface, and seal groove is arranged on the madial wall, places seal ring, and positioning pin hole is arranged on the lower end surface, by being located by connecting between locating stud and the cover plate, prevents to rotate.Several springs are arranged under the stationary seat, support stationary seat, cover plate is the frustoconic shape ring of convex, the cover plate interior edge face has positioning pin hole, by locating stud stationary seat and cover plate are located, the cover plate interior edge face has several spring base holes, and spring places in the spring base hole, and the seal ring of stationary seat madial wall is clamped on the path periphery partly of cover plate frustoconic shape ring.Several step screw holes are arranged on the cover plate, cover plate can be fixed on the housing, smear sealer between cover plate and the housing by screw.
Housing is the stepped shape ring, on the path end face screw hole is arranged, securing cover plate, step has bolt hole on the big footpath, housing can be fixed on the frame, housing with the surface of contact of frame on seal groove is arranged, place seal ring, make between housing and the frame to reach oil seal.
Vertical mixer high speed shaft Sealing of the present utility model is through stable operation over a long time, and gear-box is oil-proof, and it is applicable to all stirrers of high temperature in each chemical production device, high pressure, medium that corrosivity is strong.
