Through adopting above-mentioned technical scheme, jar mouth flange, bearing frame and gland under wholly dividing into, and all can dismantle the connection between the three, when carrying out the vulnerable part and changing, only need carry out the dismouting to the gland and can accomplish the change of vulnerable part and for repairing, and jar mouth flange, bearing frame both appear damaging down, also only need dismantle get off need change new parts can, simple and convenient and saved material resources manpower financial resources.
The utility model is further configured to: a first sealing ring is arranged between the tank opening flange and the bearing seat.
Through adopting above-mentioned technical scheme, guarantee the leakproofness between the two for the liquid of jar internal portion can not follow and flow out between the two, arouse the leakage.
The utility model is further configured to: the gland includes the bulge, it has the location sunken to cave in on the bearing frame, works as when the gland is fixed in the bearing frame, the bulge cooperation location is sunken to be fixed the tetrafluoro cover.
Through adopting above-mentioned technical scheme, fix the tetrafluoro cover for rotate and mutually support between interior axle sleeve and the tetrafluoro cover and guarantee its stable while still guaranteed sealing performance.
The utility model is further configured to: and a second sealing ring is arranged on the protruding part.
Through adopting above-mentioned technical scheme, guarantee gland and bearing frame between the two sealed for the liquid of jar internal portion can not follow and flow out between the two, arouses the leakage.
