Description
Technical field
The invention belongs to a kind of microbial fermentation equipment technical field, a kind of liquid fermentation stirring defoaming device is specifically related to.
Background technology
In microbial liquid fermentation process, zymotic fluid often produces foam, strain exponential phase is especially arrived, a large amount of foams are more also easy to produce, if eliminating these foams not in time, foam will reach fermentation tank tank deck, into in mechanical seal, retaining pressure table sensor and material-feeding port etc., cause severe contamination, and what influence was fermented is further carried out.At present, people mainly carry out froth breaking using the method for mechanical defoaming device and addition defoamer, and when addition defoamer carries out froth breaking, defoamer can suppress the growth of thalline, be unfavorable for fermentation；Existing mechanical defoaming device is that froth breaking rake is installed on agitating shaft, and froth breaking rake is rotated together with agitating shaft, and when froth is produced, the froth breaking rake of rotation smashes foam, plays froth breaking effect, but, when foam is more, froth breaking rake has little time to smash foam,
Defoaming effect is undesirable.
Chinese patent Authorization Notice No. discloses a kind of liquid fermentation defoaming device for the patent of the U of CN 202007226, the fermentation tank of jacketed, rabbling mechanism, froth breaking cylinder, the air inlet pipe for being arranged on side in fermentation tank,
Rabbling mechanism includes motor, reductor, agitating shaft, several stirrer paddles, motor is vertically set on the bearing above fermentation tank, motor is connected with reductor, agitating shaft upper end termination is fixedly connected with speed reducer output shaft, agitating shaft lower end passes through fermentation tank cover, extend perpendicularly to fermentation tank tank base, agitating shaft lower end is interval with several stirrer paddles, froth breaking cylinder is the small infundibulate of big lower mouth suitable for reading, froth breaking cylinder side is fixedly connected by fixed mount with inner tank wall, air inlet pipe is passed through from the upper lateral part of fermentation tank one, air inlet pipe lower end is suitable for reading through froth breaking cylinder, extend to the lower mouth of froth breaking cylinder.The present invention needs to be introduced from outside into air, and the air of introducing needs a gas outlet, increased the risk of pollution, and the flow velocity of the air of needs must be very big, can just make to produce negative pressure in froth breaking cylinder, by foam suction liquid, increased energy consumption.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of pure mechanic structure, the good liquid fermentation stirring defoaming device of crushing effect.
Present disclosure includes stepper motor, fermentation tank shell and motor shaft, and defoaming device and stirring vane are fixed with the motor shaft, and the defoaming device includes cover plate and the side plate being arranged on below cover plate；Through hole is provided with the cover plate.
The number of the through hole is 2-8.
Length of the distance of the motor shaft and fermentation tank outer casing bottom more than side plate.
The side plate is circular bottomless cylinder or square tube.
The fermentation tank shell upper is top cover, and support frame is fixed with the top cover, and the stepper motor is fixed on support frame.
The stirring vane is shaped as arc.
The beneficial effects of the invention are as follows, when motor shaft moves to the top, the defoaming device is located at the top of the zymotic fluid in fermentation tank shell, defoaming device includes cover plate and the side plate being arranged on below cover plate, when motor shaft is moved down, defoaming device is also moved down, due to the effect of cover plate and side plate, it is enclosed type positioned at cover plate and side plate inner space, its pressure is increasing with moving down, pressure conference destroys its internal foam, on the other hand, after cover plate submerges zymotic fluid, foam can and zymotic fluid mixing, so as to by the removal of foam.When defoaming device is moved up, and side plate bottom is when leaving zymotic fluid, and the foam between fermentation tank outer casing inner wall and side plate can enter the inner space of defoaming device due to the effect of negative pressure, so that for the froth breaking of next step is prepared.
The present invention using pressure and with zymotic fluid Forced Mixing, foam is eliminated, defoaming effect is good, have no side effect, it is to avoid the possibility that pollution is produced.
Brief description of the drawings
Accompanying drawing is structural representation of the invention.
In figure, 1 stepper motor, 2 support frames, 3 fermentation tank shells, 31 top covers, 4 motor shafts, 5 cover plates, 51 through holes, 6 side plates, 7 stirring vanes, 8 zymotic fluids.
Specific embodiment
As shown in drawings, the present invention includes stepper motor 1, fermentation tank shell 3 and motor shaft 4, and defoaming device and stirring vane 7 are fixed with the motor shaft 4, and the defoaming device includes cover plate 5 and is arranged on the side plate 6 of the lower section of cover plate 5.
Through hole 51 is provided with the cover plate 5, defoaming device is reduced in moving process, the amplitude of variation of pressure, the convenient bubble amt difference produced according to different fermentations is adjusted.
The number of the through hole 51 is 2-8.
More than the length of side plate 6, when motor shaft 4 is proceeded to bottom, cover plate 5 submerges in zymotic fluid 8 distance of the motor shaft 4 and the bottom of fermentation tank shell 3.
The side plate 6 is circular bottomless cylinder or square tube.
The top of fermentation tank shell 3 is top cover 31, and support frame 2 is fixed with the top cover 31, and the stepper motor 1 is fixed on support frame 2.
The stirring vane 7 is shaped as arc.
After stepper motor of the invention 1 starts, motor shaft 4 is moved up and down, drive fixed defoaming device and stirring vane 7 on the motor shaft (4) to move up and down, stirring vane 7 during moving up and down, due to being shaped as arc, therefore, stirring vane 7 can produce a power for rotation, be rotated around motor shaft 4, and stirring vane 7 is moved up and down and rotated, it is to make fermentation more uniform so as to be stirred to zymotic fluid 8.
When motor shaft 4 moves to the top, the defoaming device is located at the top of the zymotic fluid 8 in fermentation tank shell 3, defoaming device includes cover plate 5 and is arranged on the side plate 6 of the lower section of cover plate 5, when motor shaft 4 is moved down, defoaming device is also moved down, due to the effect of cover plate 5 and side plate 6, it is enclosed type positioned at cover plate 5 and the inner space of side plate 6, its pressure is increasing with moving down, pressure conference destroys its internal foam, on the other hand, after cover plate 5 submerges zymotic fluid, foam can and zymotic fluid mixing, so as to by the removal of foam.When defoaming device is moved up, and the bottom of side plate 6 is when leaving zymotic fluid, and the foam between the inwall of fermentation tank shell 3 and side plate 6 can enter the inner space of defoaming device due to the effect of negative pressure, so that for the froth breaking of next step is prepared.
The present invention using pressure and with zymotic fluid Forced Mixing, foam is eliminated, defoaming effect is good, have no side effect, it is to avoid the possibility that pollution is produced.
