Main equipment cavity that sealed body is correspondingly arranged and between main equipment cavity and motor flange and with the sealed body
The fixed structure of connection.
Preferably, the main equipment cavity is cone-shaped cavity.
Preferably, 7.5 ° are inclined towards the rotary shaft near the one of the rotary shaft in the main equipment cavity.
Preferably, it is additionally provided with media outlet in the main equipment cavity.
Preferably, the sealed body includes：Along the circumferentially spaced spring of the rotary shaft, with the spring two
First, second mounting seat that connects respectively of end, positioning cards between first mounting seat and spacer ring and is arranged on
Lip in first mounting seat.
Preferably, flushing hole is provided with the fixed structure, the port of the flushing hole is corresponding with lip position.
The utility model has the advantages that：
1. main equipment cavity is made into the cone chamber that one side inclines 7.5 °, the centrifugal force produced when being rotated by sealed body will
Particle throws away, then is back to media outlet, can solve the machinery when dry powder medium or media particle content are more than more than 90%
Sealing property problem, substantially increases the service life of mechanical seal.
2. the utility model is provided with lip, can prevent particle from entering anchor ring.
3. flushing hole is opened in fixed structure of the present utility model, a small amount of liquid or gas bleed can be carried out.
