Description
Technical field
The utility model relates to a kind of array intelligence heating oil bath polymerization furnace that is used for macromolecular material polymerization reaction.Relate to a kind of comparatively high temps control accuracy that has more specifically, what the variation of temperature can be with the program intelligent control, be used for that temperature of reaction is had experimental installation than the polyreaction of particular requirement.
Background technology
Some macromolecular material polymerization reaction has particular requirement to the temperature field, such as requiring uniform temperature field, causes that macromolecular material interior molecules amount is inhomogeneous in order to avoid the temperature field is inhomogeneous, influences the performance of material; Some reaction process requires the temperature field to change in time; Some reaction requires the temperature field that special shape is arranged.The usual method that obtains uniform temperature field at present is that mould is placed in the reaction boiler tube, reaction boiler tube is dipped in the oil bath, the control oil bath temperature (is normally used hydronic way, promptly obtain temperature required oil, again with being pumped in the oil bath that reaction boiler tube is housed with another one oil bath heating) with the method for the uniform temperature field that obtains high molecular weight reactive.This method control accuracy is not high, and the temperature field is even inadequately, to the variation of temperature low-response, can't obtain the required special temperature field of polyreaction; And the requirement to oil is bigger.
Summary of the invention
The purpose of the utility model device is the shape that is temperature, changes, and temperature accuracy has the macromolecular material polymerization reaction of particular requirement that the reaction unit of specific temperature field is provided.
The utility model directly is fixed on a plurality of heating temp-controlling elements in the oil bath with array, temp-controlling element divides four layers, every layer of eight element distribute with array again, thereby form the array configuration of a space multistory, the characteristics of array intelligence accurate temperature controlling at first are that each heating temperature control parts is carried out independent control, it is each heating all independent collecting temperature signal of temperature control parts and according to heating the heat-up time of setting, this method is fast to the adjusting of temperature, realized that with computer temperature being carried out numerical value PID regulates, realized intelligent control, the control accuracy height can be realized the even variation of temperature field and obtain uniform temperature field; Secondly, special different depths in oil bath is provided with agitator in this device, can better obtain uniform temperature field, has only saved a large amount of oily bath oils with an oil bath simultaneously; In addition, because some polyreaction is thermopositive reaction, for better this device of temperature control has designed the condensing agent cooling back installation in oil bath.
The utility model array intelligence heating oil bath polymerization furnace device comprises body of heater and Controlling System.Body of heater comprises furnace shell, thermal insulation layer, heating and temperature controlling device (comprising electric stove wire and thermopair).Controlling System is divided the hardware and software part.
