Description
Technical field
The utility model relates to a kind of liquid fermenting equipment, and especially a kind of defoaming device of liquid fermenting belongs to the microbial engineering field.
Background technology
In the microbial liquid fermenting process, fermented liquid tends to produce foam, especially arrived the bacterial classification logarithmic phase, the a large amount of foams of easier generation, if these foam of untimely elimination, just foam could arrive the fermentor tank tank deck, enter in the mechanical seal, retaining pressure table sensor and material-feeding port etc. cause severe contamination, and what influence was fermented further carries out.At present, people mainly adopt the method for mechanical defoaming device and interpolation defoamer to carry out froth breaking, and when the interpolation defoamer carried out froth breaking, defoamer can suppress the growth of thalline, was unfavorable for fermentation; The existing mechanical defoaming device is that the froth breaking rake is installed on stir shaft, and froth breaking is harrowed along with stir shaft rotates together, when producing foam, the froth breaking rake that rotates is smashed foam, plays the froth breaking effect, still, when foam more for a long time, froth breaking rake has little time to smash foam, defoaming effect is undesirable.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, liquid fermenting defoaming device that defoaming effect is good.
The utility model is achieved by the following technical programs:
A kind of liquid fermenting defoaming device, the fermentor tank that comprises the strap clamp cover, stirring mechanism, inlet pipe, be arranged on the froth breaking tube of a side in the fermentor tank tank body, described stirring mechanism comprises motor, step-down gear, stir shaft, several agitating vanes, described motor is vertically set on the bearing of fermentor tank top, motor is connected with step-down gear, fixedly connected with speed reducer output shaft in termination, described stir shaft upper end, the fermentor tank cover is passed in the stir shaft lower end, extend perpendicularly to the fermentor tank tank base, the stir shaft lower end is interval with several agitating vanes, described froth breaking tube is a big young doline down suitable for reading, froth breaking tube one side is fixedlyed connected with inner tank wall by anchor, described inlet pipe feeds from fermentor tank one upper lateral part, and it is suitable for reading that the froth breaking tube is passed in the inlet pipe lower end, extends to froth breaking tube end opening.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid liquid fermenting defoaming device, wherein said froth breaking tube is obliquely installed in the fermentor tank tank body, and the angle α of froth breaking tube axis and horizontal direction is 80 °～90 °; Froth breaking tube end face suitable for reading is than the high 1mm～2mm of fermented liquid liquid level.
Aforesaid liquid fermenting defoaming device, wherein said froth breaking tube bore a suitable for reading are 4～6 times of end opening bore b.
The utility model is installed a froth breaking tube simple in structure in fermentor tank, defoaming effect is good.During fermentation, sterile air enters fermentor tank from the inlet pipe lower end, because the gas that enters produces certain flow velocity, air-flow is vacuum space of interruption-forming under the froth breaking tube, when fermented liquid produced foam, under the air pressure effect, foam was from the froth breaking tube froth breaking tube end opening that is drawn onto suitable for reading, mix with sterile air and fermented liquid, reach and eliminate the foamy purpose.The froth breaking tube is obliquely installed in fermentor tank, and its bore suitable for reading makes that greater than the end opening bore the utility model defoaming effect is more obvious.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprise strap clamp cover 1 fermentor tank 2, stirring mechanism 3, inlet pipe 4, be arranged on the froth breaking tube 5 in left side in fermentor tank 2 tank bodies, stirring mechanism 3 comprises motor 31, step-down gear 32, stir shaft 33, several agitating vanes 34; Motor 31 is vertically set on the bearing 35 of fermentor tank 2 tops, motor 31 is connected with step-down gear 32 by shaft coupling, stir shaft 33 upper ends are bearing in the bearing 35 by bearing, fixedly connected with step-down gear 32 output shafts in its termination, upper end, the cover of fermentor tank 2 is passed in stir shaft 33 lower ends, extend perpendicularly to fermentor tank 2 tank base, stir shaft 33 lower ends are interval with several agitating vanes 34; Froth breaking tube 5 is a big young doline down suitable for reading, the employing trade mark is that the stainless material of SUS316L is made, the 51 bore a suitable for reading of froth breaking tube 5 are 4～6 times of end opening 52 bore b, the 51 bore a suitable for reading of present embodiment froth breaking tube 5 are 5 times of end opening 52 bore b, be convenient to collect foam, satisfy the flow velocity requirement of fermented liquid in the froth breaking tube 5 simultaneously.Froth breaking tube 5 is obliquely installed in the tank body of fermentor tank 2, the angle α of its axis and horizontal direction is 80 °～90 °, the angle α of present embodiment is 85 °, make fermented liquid form interior circulation easily, defoaming effect is more obvious, 51 end faces suitable for reading of froth breaking tube 5 are than the high 1mm～2mm of fermented liquid liquid level, and its left side is fixed on fermentor tank 2 inwalls by upper holder 6 and lower fixed frame 7 respectively.Inlet pipe 4 feeds from fermentor tank 2 left upper portion, and the suitable for reading 51 of froth breaking tube 5 passed in the lower end, extends to the end opening 52 of froth breaking tube 5.
