Description
Technical field
This utility model is related to a kind of Multifunctional vacuum tank, belongs to technical field of chemical.
Background technology
Industrial production methoxy polyethylene glycol methacrylate-styrene polymer, usually by methoxy poly (ethylene glycol) and metering system
Sour and some other adjuvant (p-methyl benzenesulfonic acid, polymerization inhibitor etc.) put into esterification tank in, airtight be warming up to 150 DEG C, evacuation is anti-
Answer 2 hours, the water sucking filtration that esterification generates out, is collected in vacuum tank by condenser.Take out once every half an hour, take out
Filtrate is also collected to vacuum tank.After reaction terminates, smoke filtrate returns in esterification tank so that it may obtain methoxy poly (ethylene glycol) methyl
Acrylate.
When in high temperature evacuation, the methacrylic acid of part vaporization is drawn out of, by cold together with the water of esterification generation
Condenser cooling generates liquid and collects in vacuum tank.According to chemical examination, because esterification is not in first time smoke filtrate, take out
The content of the methacrylic acid in filtrate reaches more than 20%.When ambient temperature is less than 15 DEG C, the methacrylic acid in smoke filtrate
It is also easy to produce auto polymerization and cannot use.For ensureing the carrying out producing it will usually add the inhibition of certain ppm concentration in smoke filtrate
Agent.But existing vacuum tank cannot add polymerization inhibitor it is impossible to meet user's request into tank.
Additionally, it will usually cause filtrate suck-back due to the suddenly change of air pressure during vacuum drawn, affecting product
Quality.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional vacuum tank, can conveniently add polymerization inhibitor, can prevent liquid again
Body suck-back.
For achieving the above object, this utility model employs the following technical solutions: a kind of Multifunctional vacuum tank, including cover,
Tank body, vacuum pump, it is arranged at the inlet on tank body top and is arranged at the liquid outlet of tank base, described cover and described tank body
Connect, described inlet is connected with condenser by connecting tube, described liquid outlet is connected with esterification tank, the setting of described cover top
There is extraction valve, described vacuum pump is connected with described extraction valve by vacuum line, and described cover is provided with pressure transducer, described
Pressure transducer is connected with travel switch by control circuit, and described travel switch is arranged in connecting tube, and described cover is opened
There is observation port, in described observation port, be embedded with transparency glass plate, described cover also has screw hole, described screw hole is connected with
Control valve, described tank wall is provided with liquidometer.
Further, described cover and the contact site of the contact site, cover and transparency glass plate of tank body are provided with
Seal washer.
Further, described connecting tube is stainless steel tube.
Further, described vacuum tank also includes support, and described tank body is arranged on support.
This utility model passes through to open up screw hole on cover, and is connected with control valve, can facilitate operator into tank
Add polymerization inhibitor；The pressure state of the pressure transducer energy monitor in real time vacuum tank of setting, when air pressure suddenly change, pressure passes
Sensor controls travel switch to close connecting tube by control circuit, is simultaneously emitted by alarm, prevent filtrate suck-back and returning charge flow back to cold
In condenser；The ruuning situation in vacuum tank can conveniently be observed by the observation port of setting, finds and solve bursting problem in time, preferably
Meet customer need.
