Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, further elucidate this utility model, it should be understood that these embodiments are only used for
Illustrate this utility model rather than limit scope of the present utility model, after this utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.Implement
Example 1
A kind of oxygen concentration real-time monitoring system of vinegar solid state fermentation equipment, as shown in accompanying drawing 1-2, including horizontal revolving drum
The tank body 1 of fermentation tank, raw vinegar turn over unstrained spirits with tank body slow rotation in tank body, and due to being solid fermentation, therefore raw vinegar amount is more,
Usually 60% of tank volume or so, also including oxygen concentration sensor 2, PLC, oxygen concentration sensor 2 is from tank
Inside is inserted into through tank skin outside body 1, for the oxygen concentration in Real-time Collection tank body, oxygen density value telecommunications is changed into into
Number PLC is passed to, the signal transmission between oxygen concentration sensor 2 and PLC can be wire transmission, also may be used
Being to be wirelessly transferred.During wire transmission, oxygen concentration sensor also has swivel joint with the junction of tank body.
In raw vinegar sweat, 1 most times of tank body of horizontal revolving drum fermentation tank are in halted state, during stopping
Position is fixed, with the tank body stop position as position of fermenting, according to the position characteristics of raw vinegar material position 5 in tank, to oxygen concentration
Sensor, the air inlet of oxygen, the gas outlet of tank body carry out special arrangement.
Oxygen concentration sensor 2 arranges one, and it is to insert tank body 1 along 1 diametric(al) of tank body.In length of tank L side
It is centrally located upwards, tank body fermentation position top area is located on tank body height D directions, above raw vinegar material position 5.
Air inlet 3, gas outlet 4 are offered on tank body 1, external pipe is connected with respectively.Air inlet 3 is located at 1 top of tank body
The raw vinegar region of 1 bottom of raw vinegar upper area and tank body, two, top air inlet, the air inlet of bottom two, to above raw vinegar and
Raw vinegar delivered inside compressed air, is met the demand to oxygen in sweat, is provided with electricity on the pipeline being connected with air inlet
Magnet valve is switched, and air inlet can be relative to the vertical centrage of tank body 1 deflection certain angle α, it is also possible to vertical up and down two
End position, air inlet can symmetrical, symmetrical above and below settings.Gas outlet 4 is located at the top of tank body 1, and on length of tank L directions
Positioned at end positions.
Electromagnetic valve switch is controlled by PLC, preset in PLC operation electromagnetic valve switch open,
The reference oxygen density value of closing.The oxygen density value of collection is changed into the signal of telecommunication and passes to PLC controls by oxygen concentration sensor
Device processed, PLC are used to parse, analyze, judge oxygen concentration signals, and make operational order, and control electromagnetic valve switch is beaten
Open or close and close.
By taking the horizontal revolving drum fermentation tank that length of tank L is as 5m, tank body radius R is as 1.3m as an example, earlier fermentation, setting
The oxygen concentration that air inlet duct solenoid switch is opened is 18%, and the oxygen concentration that electromagnetic valve switch is closed is 21%, is sent out
In the ferment later stage, the oxygen concentration of electromagnetic valve switch opening is set as 15%, the oxygen concentration that electromagnetic valve switch is closed is 18%.In real time
Oxygen density value in monitoring tank, when which is reduced to opens the critical concentration of electromagnetic valve switch, then PLC provides instruction and beats
Open electromagnetic valve is switched, and compressed air is passed through in tank；When in tank, oxygen density value reaches the critical concentration of closed electromagnetic valve, then
PLC provides instruction and closes electromagnetic valve switch, stops ventilation.So as to oxygen needed for the fermentation of intelligent control raw vinegar, it is ensured that food
Vinegar solid fermentation is normally carried out.
Embodiment 2
Difference with embodiment 1 is：
By taking the horizontal revolving drum fermentation tank that length of tank L is as 5.5m, tank body radius R is as 1.4m as an example, earlier fermentation, if
The oxygen concentration for determining air inlet duct solenoid switch opening is 17%, and the oxygen concentration that electromagnetic valve switch is closed is 21%,
In the fermentation later stage, the oxygen concentration of electromagnetic valve switch opening is set as 14%, the oxygen concentration that electromagnetic valve switch is closed is 19%.It is real
When monitoring tank in oxygen density value, when its be reduced to open electromagnetic valve switch critical concentration when, then PLC provides instruction
Electromagnetic valve switch is opened, compressed air is passed through in tank；When in tank, oxygen density value reaches the critical concentration of closed electromagnetic valve,
Then PLC provides instruction and closes electromagnetic valve switch, stops ventilation.So as to oxygen needed for the fermentation of intelligent control raw vinegar, it is ensured that
Vinegar solid fermentation is normally carried out.
