Description
Technical field
The utility model is related to a kind of sealing device, especially a kind of high speed powder mixer axle gas sealing mechanism.
Background technology
Sealing is to prevent leak fluid or solia particle leakage, and prevents introduced contaminants such as dust and moisture etc. from invading,
Labyrinth seal is that several belt sealing teeth being arranged in order are set around rotating shaft, and a series of gaps of damming are formed between tooth and tooth
With expansion cavity, sealed medium produces throttle effect and reaches the purpose of Drain Resistance at the gap by tortuous labyrinth, labyrinth
Seal gas can be uniformly dispersed main shaft periphery by ring, and current sealing ring is single hole, due to needing labyrinth annular distance pair
Quasi- sealing shroud air-filled pore, it is impossible to enough at will to install, labyrinth seal has good sealing under high temperature, high pressure, speed conditions high,
Long service life, but labyrinth seal machining accuracy is high, and it is more difficult to assemble, it is impossible to prevent the leakage of gas completely, often because unit is operated
Bad and wear and tear, sealing property is greatly reduced, it is necessary to changed after abrasion, mostly time-consuming when existing technology changes sealing
Arduously, efficiency is reduced.
Utility model content
The purpose of this utility model is directed to defect present in high speed powder mixer axle hermetic seal prior art, and carries
For a kind of high speed powder mixer axle gas sealing mechanism.
The technical solution of the utility model is：A kind of high speed powder mixer axle gas sealing mechanism, including mix arbor, stir
The wing, wear-resistant sleeve, porous labyrinth ring, sealing jacket gland, mixed organism, sealing shroud, inlet suction port and Simmer ring are mixed, its feature exists
In the both sides of the mixing arbor are provided with the wear-resistant sleeve, and the agitator is connected with the both sides of the mixing arbor, described
Porous labyrinth ring is connected with the Simmer ring, and the upper end of the sealing shroud is provided with sealing jacket gland, the mixed organism with
The sealing shroud connection, the sealing shroud connects the inlet suction port.
Further, the porous labyrinth ring is provided with two air chambers of interior air chamber and outer air chamber, has between two air chambers
Multiple holes communicate.
Further, the sealing shroud is provided with two screws, and the screw is M10.
Further, the lower end of the wear-resistant sleeve is provided with the centrifugal pan being connected with the mixing arbor.
The beneficial effects of the utility model are：Porous labyrinth ring has inside and outside two air chambers, has multiple holes in the middle of two air chambers
Communicate, porous labyrinth ring can be evenly dispersed in seal gas around mixer main shaft, with easy to install, due to
There is outer air chamber without the hole of porous labyrinth ring being directed at the air-filled pore of sealing shroud, can at will install, when greatling save installation
Between, improve installation effectiveness；Two M10 screws sealing shroud easy to disassemble when Simmer ring is changed is designed on sealing shroud, is had
Simple structure, practicality is high.
