Description
Technical field
The utility model relates to liquid agitation machinery field, particularly a kind of recirculation unit.
Background technology
The viscosity of dropping polymerisation the upper and lower of reactor when viscosity is larger of Liquid polymeric is different, although there is the existence of stirring, but still have the concentration difference of levels, the size being reflected in molecular weight of material is also different, that is the relative broad range of molecular weight is large, is unfavorable for the choice and operation of client.
Summary of the invention
For the problem that fluid molecule levels concentration difference in reactor in prior art is large, the utility model provides a kind of recirculation unit, solve levels concentration difference problem of non-uniform, in order to achieve the above object, the utility model is by the following technical solutions: the utility model comprises reactor 1, circulating pump 2, sensor 3, PLC 4, described reactor 1 top is provided with charging aperture 11, Power Available Shaft 12, the agitating device 13 be connected with Power Available Shaft 12 is provided with in described reactor 1 internal cavities, liquid level gauge 14, at least two concentration sensors 3, discharging opening 15 is provided with bottom described reactor 1,
