The temperature cascade control device comprises an exhaust valve and pressure meter, the middle of the side wall of a fermentation tank is communicated with a hot water tank through a pipeline and a first ball valve, an outlet of the hot water tank is connected to the lower portion of the side wall of the fermentation tank through a hot water pump, a one-way valve and a second ball valve which are connected in series, external tap water is connected between the one-way valve and the second ball valve through a third ball valve and an electromagnetic valve which are connected in parallel, the lower portion of the side wall of the fermentation tank is further connected with a blow-off pipe through a fourth ball valve, a temperature sensor is positioned in the fermentation tank, and control ends of the electromagnetic valves are correspondingly connected with output driving ends of the external temperature sensor respectively. As heating and cooling inside the fermentation tank are omitted, the internal temperature of the biological fermentation tank is controlled, the temperature of a fermentation environment can be kept balanced, and normal growth of microorganisms is promoted.
Description
Technical field
The utility model is the temperature controlling system for biological fermentation process, plays the effect of the temperature of material in the overbalance tank, belongs to the technical field of biological fermentation.
Background technology
Microorganism during the fermentation, must have the environment that is beneficial to its growth and could keep normal fermenting procedure, generally, people understand inside reactor microbial growth situation by the numerical value of observing thermometer, and constantly regulate according to the numerical value of reflection.But owing to the generation of Special Circumstances, thermometer can't reflect the biological fermentation temperature in the tank, and the fermentation rate of microorganism is not understood sometimes, simultaneously, operator such as careless slightly fail in time to pinpoint the problems and regulate, thereby can cause the disadvantageous growing environment of microorganism.In order to address this problem, we can keep the balance of yeasting temperature by this device, impel the normal growth of microorganism.
Summary of the invention
Technical problem: the purpose of this utility model provides the temperature cascade control device in a kind of fermentation process, owing to need not heating and cooling in fermentor tank, solved the temperature control problem in the biological fermentation tank, the balance that can keep the yeasting temperature, simulate to greatest extent the optimum temps environment of biological growth, impel the normal growth of microorganism.
Technical scheme: the temperature cascade control device in the fermentation process of the present utility model comprises temperature sensor, hot well tank, hot water pump, the first ball valve, the second ball valve, the 3rd ball valve, the 4th ball valve, magnetic valve, check valve; Crossing the first magnetic valve at the sidewall middle part of fermentor tank by device for cleaning pipeline is communicated with hot well tank, the outlet of hot well tank connects the lower sidewall of fermentor tank by hot water pump, check valve, the second ball valve that is in series, outside tap water is connected between check valve and the second ball valve by the 3rd ball valve and the magnetic valve that connects that be in parallel, the lower sidewall of fermentor tank also connects blow-off pipe by the 4th ball valve, temperature sensor is positioned at fermentor tank, and be connected with temperature regulator, each output terminal of temperature regulator is corresponding respectively to be connected with each ball valve.
By this device, when the temperature drift of fermentation, temperature sensor is found a signal after detecting actual temperature in the tank, and magnetic valve is opened, and tap water (cold water) enters in the chuck and circulates, and the temperature in the tank will reduce; When the temperature of fermentation was on the low side, temperature sensor was found a signal after detecting the interior actual temperature of tank, closed electromagnetic valve, and the electrothermal tube in recycle pump and the water tank starts, and hot water just enters in the chuck and circulates, and the temperature in the tank will be gone up.Beneficial effect: because the major advantage of tandem control has:
1. interference is added in the subloop, by subloop control it is suppressed;
2. the variation of parameter in the subloop is controlled by subloop, and the impact of controlled volume is greatly weakened;
3. the inertia of subloop is regulated by subloop, thereby has improved the response speed of whole system.
By this device, when the temperature drift of fermentation, temperature sensor sends a signal after detecting actual temperature in the tank, and magnetic valve is opened, and tap water (cold water) enters in the chuck and circulates, and by thermal conduction, the temperature in the tank will reduce; When the temperature of fermentation was on the low side, temperature sensor sent a signal after detecting the interior actual temperature of tank, closed electromagnetic valve, and the electrothermal tube in recycle pump and the water tank starts, and hot water just enters in the chuck and circulates, and by thermal conduction, the temperature in the tank will be gone up.The balance that can keep the yeasting temperature is simulated the optimum temps environment of biological growth to greatest extent, and the impact of reduce disturbance impels the normal growth of microorganism.
