Abstract
The utility model discloses a kind of defoaming device of fermenter, comprise tank body, described tank body upper end is fixedly installed motor, stirring rake is provided with in described tank body, described stirring rake connects motor by stir shaft, and described stir shaft middle-end is socketed with froth breaking oar by axle sleeve, described froth breaking oar is provided with some three grades of reducing froth breaking holes, described stir shaft is provided with position adjustments hole, described axle sleeve is provided with setting nut.The shearing force that the utility model produces when relying on foam by the pressure change that produces during reducing hole and rotate eliminates foam, have the advantages that structure is simple and power consumption is low, defoaming effect is good simultaneously, and on-line velocity can rapidly by the removal of foam more than during 5m/s.
Description
Technical field
The utility model belongs to fermentor tank defoaming technology field, is specifically related to a kind of defoaming device of fermenter.
Background technology
Fermentable is a kind of biological process of complexity, and in this production process, have several factors needs to regulate and control, and the such as supply etc. of substratum, sterilization time, temperature, pH value, oxygen, the control of foam is also wherein important one.Foam is a large amount of gas dispersion dispersion system in a liquid, and its disperse phase is gas, and external phase is fermented liquid.The generation of a large amount of foam can cause huge harm to explained hereafter, as reduced throughput, affecting quality product, affecting normally carrying out of production, this just needs people to eliminate foam by various method, and conventional mode has 2 kinds: one is chemical froth breaking, and one is mechanical defoaming.
The method of chemical froth breaking is adopted to be add defoamer, defoamer in use, preferably join once in fermentor tank along with bed material in the early stage of carrying out of fermenting, and foam can be controlled generate or eliminate foam in whole fermenting process, be conducive to like this preventing fermenting process microbiological contamination, but practical situation are not often like this, defoamer can lose activity in use procedure, thus ability that is out of hand or froth breaking, this just needs to adopt the method repeatedly marginally added when using defoamer, will certainly increase the chance of microbiological contamination like this.Use defoamer that pH value also can be made to reduce too much, fermented liquid dissolved oxygen ability is significantly declined, this is totally unfavorable for aerobic fermentation.In recent years, along with the rise of oil price, synthesis defoamer cost also has the trend of rise.Due to the existence of these unfavorable factors, the use of defoamer obtains restriction in many occasions.
By the continuous change that mechanical force froth breaking is then by the sharp pounding caused by mechanical force or pressure, impel lather collapse, to reach the object of froth breaking, and at present conventional mechanical defoaming device mainly contains rake, rotational circle is board-like, shock-wave reflection is board-like, the defoaming device of these structures needs external motor to drive mostly, and defoaming effect is general, especially cannot play eliminating effect especially to stream-like foam.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of shearing force produced when relying on foam by the pressure change that produces during reducing hole and rotate to eliminate the defoaming device of fermenter of foam.
The technical scheme that the utility model adopts is: a kind of defoaming device of fermenter, comprise tank body, described tank body upper end is fixedly installed motor, stirring rake is provided with in described tank body, described stirring rake connects motor by stir shaft, and described stir shaft middle-end is socketed with froth breaking oar by axle sleeve, described froth breaking oar is provided with some three grades of reducing froth breaking holes, described stir shaft is provided with position adjustments hole, described axle sleeve is provided with setting nut.
As the further setting of such scheme, described hole, three grades of reducing froth breaking holes, froth breaking oar blade both sides is on the contrary.
As the further setting of such scheme, described motor is stepper-motor.
The shearing force that the utility model produces when relying on foam by the pressure change that produces during reducing hole and rotate eliminates foam, have the advantages that structure is simple and power consumption is low, defoaming effect is good simultaneously, and on-line velocity can rapidly by the removal of foam more than during 5m/s.

Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
As shown in Figure 1-Figure 3, a kind of defoaming device of fermenter of the present embodiment, comprise tank body 1, described tank body 1 upper end is fixedly installed motor 2, is provided with stirring rake 3 in described tank body 1, and described stirring rake 3 connects motor 2 by stir shaft 4, described stir shaft 4 middle-end is socketed with froth breaking oar 6 by axle sleeve 5, described froth breaking oar 6 is provided with some three grades of reducing froth breaking holes 7, described stir shaft 4 is provided with position adjustments hole 8, described axle sleeve 5 is provided with setting nut 9.
As the further setting of such scheme, hole, three grades of reducing froth breaking holes 7, described froth breaking oar 6 blade both sides is on the contrary.
As the further setting of such scheme, described motor 2 is stepper-motor.
The shearing force that the utility model produces when relying on foam by the pressure change that produces during three grades of reducing froth breaking holes 7 and rotate eliminates foam, have the advantages that structure is simple and power consumption is low, defoaming effect is good simultaneously, and on-line velocity can rapidly by the removal of foam more than during 5m/s.
