Description
Technical field
The utility model is related to a kind of PVDF liquid phase polymerizers, belong to polymerizing reactor technical field.
Background technology
At present, polymeric kettle be PVDF production capital equipment, polymerisation need high temperature, high pressure, cleaning environment under
It carries out, so the requirement to mechanical seal must reach a high temperature, high pressure, the standard of No leakage, under this production environment, machinery
Sealing bears huge pressure for a long time, influences service life.
Utility model content
The purpose of the utility model is to overcome drawbacks described above existing for existing polymeric kettle, it is proposed that a kind of PVDF liquid phases are gathered
Kettle is closed, realizes the effect without pressure difference before and after mechanical seal, so as to the service life of prolonged mechanical sealing.
The utility model is realized using following technical solution：
A kind of PVDF liquid phase polymerizers, the manhole cover including autoclave body and at the top of autoclave body, the top of the autoclave body are equipped with
Hand hole and feed inlet, the outside of the autoclave body are socketed with chuck, and the inside of the autoclave body is equipped with agitating device, the autoclave body
Bottom is equipped with mechanical seal, and the agitating device includes stirring motor, agitating shaft and agitating paddle, and agitating shaft passes through mechanical seal
It is connected with stirring motor, the manhole cover is equipped with rupture disk and gaseous pressure balance pipe, the gaseous pressure balance pipe connection
The input port of liquid seal can, the bottom of the liquid seal can are set there are two one end connection of delivery outlet, a delivery outlet and mechanical seal,
Another delivery outlet is connected by cooling collar and the other end of mechanical seal.
Further, the agitating paddle includes lower floor's hinged joint type blade and upper strata drive-in blade, so sets and causes
The resistance that agitating paddle is subject in whipping process is smaller, while can carry out good action of turbulent flow to material web so that stirring is more
Uniformly.
Further, the feed inlet is connected with the material bottom insert canal towards autoclave body bottom, can effectively prevent material punching
Hit generation electrostatic.
Further, it is also equipped with ear mount on the autoclave body side wall.
Further, the input port of the liquid seal can and delivery outlet are mounted on valve.
The beneficial effects of the utility model are：
Input, the delivery outlet connection of polymeric kettle and liquid seal can, pressure is essentially identical before and after making mechanical seal, keeps machinery close
Envelope is front and rear without pressure difference, while the cooling water liquid cooling in cooling collar intraformational bed, and liquid circulation is made to take away at mechanical seal
Rub the heat generated, prolongs the service life.
