Abstract
The invention relates to an energy-saving stirred fermentor comprising a fermentor body, a stirring mechanism, an air conduction system and a deceleration transmission mechanism. The invention is characterized in that the air outlet opening of the intake pipe of the air conduction system faces the center of the fermentor bottom; inner spiral slices for air conduction are evenly distributed in the air outlet of the intake pipe; the inner spiral slices for air conduction conducts the rotary direction of air to be the same with the rotary direction of a stirring shaft; outer spiral slices for air conduction are fixed on the fermentor bottom below the air outlet of the intake pipe; the outer spiral slices for air conduction conduct the rotary direction of air to be the same with the rotary direction of a stirring shaft. The energy-saving stirred fermentor has the characteristics of simple structure, low energy consumption, high efficiency, thorough sterilization, convenient operation and maintenance and the like and also improves air utilization ratio.
Description
Technical field
The present invention relates to a kind of fermentative prodn equipment, particularly a kind of energy-saving stirred fermentor.
Background technology
In the fermentation equipment of numerous types,, be widely used in every field such as microbiotic, amino acid, Hydrocerol A because the high oxygen consumption requirement of leavened prod mostly has ventilation concurrently and is with churned mechanically standard type fermentor tank purposes the most general again.The key problem in technology of fermentor tank design is stirring mechanism, and the performance of stirring mechanism is directly connected to absorption and the metabolism that the growth of bacterial classification, form, oxygen and pipe are supported thing, directly has influence on fermentation unit and productive rate thus.The structure of stirred fermentor generally comprises tank body, stirring system and gas directing system and reduction gearing mechanism at present.Tank body is provided with dog-house and inlet, outlet; Stirring system comprises stir shaft and several whisking appliances; The whisking appliance layering is installed on the stir shaft, and the whisking appliance that bottom is installed is generally the disc turbine formula whisking appliance that is used for gas dispersion, and stirring system adopts the reduction gearing mechanism transmission.Gas directing system has the porous of employing ring pipe at present, has a plurality of production wells in the ring pipe bottom, and this intake method can be realized gas dispersion relatively uniformly, but material easy blocking pore, thus cause sterilization not thorough.Therefore using maximum is the single hole pipe, and the air outlet opening of the inlet pipe of gas directing system is at the bottom of jar, and this air intake system structure is fairly simple, can also eliminate the solid materials of tank body simultaneously.But this air intake structure causes the retrograde rotation of whipping device through regular meeting, thereby the power consumption that causes whipping device rises, and can not restart after can causing parking when serious.Though the disk of bottom disc turbine whisking appliance has stoped the short circuit of gas, also caused the inhomogeneous of disk top gas distribution.
Summary of the invention
The objective of the invention is to provides a kind of energy-saving stirred fermentor reasonable in design, simple in structure for the deficiency that overcomes prior art; Can make full use of the energy that air inlet has; Reduce the power of stirring mechanism, improve the distribution consistency degree of gas simultaneously, improve the gas utilising efficiency.
The objective of the invention is to adopt such technical solution to realize: a kind of energy-saving stirred fermentor; Comprise tank body, stirring mechanism, gas directing system and reduction gearing mechanism; Stirring mechanism comprises stir shaft and several whisking appliances, and the whisking appliance layering is installed on the stir shaft, and the whisking appliance that bottom is installed is the disc turbine formula whisking appliance that is used for gas dispersion; Stirring mechanism adopts the reduction gearing mechanism transmission; It is characterized in that: opening center at the bottom of jar, inlet pipe air outlet of said gas directing system, said inlet pipe is evenly equipped with the air guide inner screwy fin in the air outlet, and the direction of said air guide inner screwy fin guiding gas rotation is consistent with the stir shaft sense of rotation; The jar end of the below of said inlet pipe air outlet, be fixed with air guide external spiral sheet, and the direction of said air guide external spiral sheet guiding gas rotation is consistent with the stir shaft sense of rotation.
Compared with prior art, the invention has the beneficial effects as follows: because the jar end of the below of inlet pipe air outlet and inlet pipe air outlet is equipped with the air guide flight, the gas that gas directing system is got into can rise by homodisperse; Because the direction of air guide flight guiding gas rotation is consistent with the stir shaft sense of rotation, air inlet forms power-assisted to the rotation of whipping device simultaneously, thereby promotes the power consumption of whipping device to descend save energy.

Embodiment
As shown in Figure 1; Energy-saving stirred fermentor still comprises tank body 1, stirring mechanism, gas directing system and reduction gearing mechanism 2; Inlet pipe 3 air outlet opening centers at the bottom of jar of gas directing system, tank body 1 is provided with dog-house and inlet, outlet, and stirring system comprises stir shaft 4 and several whisking appliances 5; Whisking appliance 5 is generally 2-4; Whisking appliance 5 layerings are installed on the stir shaft 4, are provided with 3 whisking appliances 5 among the present invention, and the whisking appliance 5 that bottom is installed is generally the disc turbine formula whisking appliance 5 that is used for gas dispersion; The blade cross section of disc turbine formula whisking appliance 5 can be parabola shaped or half elliptic or semi-circle tubular or plate shaped a kind of, and stirring system adopts reduction gearing mechanism 2 transmissions.Like Fig. 2, shown in 3; In inlet pipe 3 air outlets, be evenly distributed in air guide inner screwy fin 6 along inwall; Air guide inner screwy fin 6 has certain inclination angle and is fixed on guiding gas rotation on the inwall of inlet pipe 3 air outlets, and the direction of air guide inner screwy fin 6 guiding gas rotation is consistent with stir shaft 4 sense of rotation; As shown in Figure 2; The jar end of the below of inlet pipe 3 air outlets, be fixed with air guide external spiral sheet 7; All air guide external spiral sheets 7 are the setting of radiation direction around a jar center, the end; A circular space is preferably reserved in the centre, the 7 curved and consistent guiding gas rotations of direction of air guide external spiral sheet, and the direction of air guide external spiral sheet 7 guiding gas rotation is same consistent with stir shaft 4 sense of rotation.The quantity of air guide inner screwy fin 6 and air guide external spiral sheet 7 is 3～8 and is advisable.As shown in Figure 4, in order to let disk top gas distribution more even of disc turbine formula whisking appliance 5, also on the disc face of disc turbine formula whisking appliance 5, be provided with a plurality of ventilating pits 8 in the present embodiment, ventilating pit 8 is preferably along the circumference uniform distribution.
The jar end of the below of these energy-saving stirred fermentor inlet pipe 3 air outlets and inlet pipe 3 air outlets, be equipped with the air guide flight, and the gas that gas directing system is got into can rise by homodisperse; Because the direction of air guide flight guiding gas rotation is consistent with stir shaft 4 sense of rotation, air inlet forms power-assisted to the rotation of whipping device simultaneously, thereby promotes the power consumption of whipping device to descend save energy.
