Description
Technical field
The utility model relates to chemical field, is specifically related to a kind of degassed still.
Background technology
Degassed still is equipment conventional in Chemical Manufacture, is applicable to the monomer polymerization reactions under oxygen barrier, low pressure.In polymerization process, need sampling inspection.During sampling, need to close vacuum system and the vacuum laid down in degassed still, otherwise after opening the outlet valve of the bottom of degassed still, because ambient pressure is greater than degassed still internal gas pressure, be difficult to sample for inspection from the bottom blowing of degassed still.Therefore be necessary to design a kind of sampling degassed still easily.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides sampling degassed still easily.
For this reason, degassed still of the present utility model, comprises kettle; Kettle is provided with agitator, and kettle top is provided with charging aperture and bleeding point, and autoclave body bottom is provided with discharging opening; Bleeding point connects the first vacuum extractor through the first vacuum pumping valve, and the discharging opening of kettle is communicated with feeding pipe through baiting valve, and the outlet of feeding pipe is provided with take-off valve, and feeding pipe is vertically arranged.
Compared with traditional degassed still, the degassed still of the utility model by arranging feeding pipe, and controls material turnover feeding pipe in kettle by baiting valve and take-off valve; When needing sampling, without the need to laying down the vacuum in kettle, only need open baiting valve, keep take-off valve to close, because kettle internal gas pressure is low, feeding intraductal atmospheric pressure is high, and the air in feeding pipe is drawn into kettle, and in kettle, material enters probe tube; Turn off baiting valve subsequently, open take-off valve, then namely the material in probe tube vertically flows out from feeding pipe, completes feeding.Feeding pipe is vertically arranged, and makes the material in kettle can slip into and skid off feeding pipe swimmingly, makes reclaiming process more smooth and easy.
In order to avoid waste, for convenience detach clean, the preferred technical scheme of the utility model is, the volume of described feeding pipe is the volume detecting required material.
For the ease of connecting, the preferred technical scheme of the utility model is, described autoclave body bottom discharging opening and described baiting valve, described baiting valve and described feeding pipe and described take-off valve and described feeding pipe are Flange joint.In monomer polymerization process, sometimes need gradation to feed in raw material, comprise monomer and auxiliary agent; And the general bulky of kettle, from top-feed trouble and pipeline is long, power consumption is greatly.The conveniently interpolation of auxiliary agent, the preferred technical scheme of the utility model is, the side of described feeding pipe is communicated with auxiliary agent adding tube, and auxiliary agent adding tube connects the flexible pipe be used for from auxiliary agent bucket suction auxiliary agent through auxiliary agent valve.When needing to add auxiliary agent in kettle, also without the need to turning off vacuum extractor or laying down vacuum, only need flexible pipe to be stretched into below the liquid level in auxiliary agent bucket, open baiting valve, keep take-off valve to close, under kettle vacuum condition, the auxiliary agent in auxiliary agent bucket can be pumped in kettle.
Before opening baiting valve, be air in probe tube, it is pumped into kettle can destroy air pressure conditions in kettle to a certain extent.In order to make sampling also not affect air pressure conditions in kettle, preferred technical scheme is, the side of described feeding pipe is communicated with vacuum-pumping tube, and vacuum-pumping tube connects the second vacuum extractor through the second vacuum pumping valve.
Aforesaid way arranges the second vacuum extractor, and the material entered in feeding pipe may block the bleeding point of the second vacuum pumping valve.In order to avoid blocking the second vacuum pumping valve, the preferred technical scheme of the utility model is, the outlet connecting tee pipe of described take-off valve, and three-way pipe comprises the supervisor vertically arranged and is responsible for side perpendicular to being responsible for and being communicated with supervisor the arm arranged with being located at; One end of supervisor connects the outlet of described take-off valve, and the other end connects outlet valve, and arm connects the second vacuum extractor through the second vacuum pumping valve.By the second vacuum extractor being arranged on the three-way pipe arm of take-off valve lower end connection, before sampling, first open take-off valve and the second vacuum pumping valve, baiting valve and outlet valve is kept to close, start the second vacuum extractor, vacuumize to probe tube, make in it, to reach the air pressure conditions close with kettle; Stop the second vacuum extractor subsequently, close the second vacuum pumping valve and take-off valve, open baiting valve, outlet valve, make material in kettle enter probe tube; Finally close baiting valve, open outlet valve, the material in probe tube is flowed out through the supervisor of three-way pipe.Due to closedown baiting valve, open outlet valve before, bleeder valve is opened, and therefore three-way pipe keeps same pressure with the external world, therefore material is when flowing out from feeding pipe through three-way pipe, not again can aspirate by the second vacuum extractor and block the second vacuum pumping valve.
Advantage of the present utility model and beneficial effect are: the utility model degassed still feeding is smooth and easy, and reclaiming process, without the need to turning off the vacuum extractor of degassed still or shedding vacuum, saves the feeding time, ensure that the stable of sintetics quality.And economize in raw materials, be convenient to clean and be convenient to add auxiliary agent.Through further improving, can also sample when not affecting vacuum condition in degassed still, also can further improve product quality.
