The utility model has the advantage of simple structure, with low costs, dosage adds accurately, convenient to use.
Description
Technical field
The utility model relates to fermentable production pH value setting device, especially relates to a kind of ammoniacal liquor automatic adding device.
Background technology
In fermentable suitability for industrialized production, often need to regulate the pH value of fermented liquid to ensure the normal growth demand of microorganism, traditional mode of production is the height that method that the degree of being opened by regulated valve manually or number of times add ammonia soln carrys out adjust ph, operation is comparatively complicated, and accurate not.Although have PLC automatic control system to carry out pH value at present automatically to regulate, cost of investment is large.
Summary of the invention
The utility model object is to provide the ammoniacal liquor automatic adding device that a kind of cost is low, level of automation is high.
For achieving the above object, the utility model can take following technical proposals:
Ammoniacal liquor automatic adding device described in the utility model, comprises ammonia water tank body; Described ammonia water tank body side is provided with open-topped water tank, ammonia water tank bodies top is provided with inlet mouth and air outlet, described inlet mouth is provided with vacuum breaker, be communicated with in described air outlet and be provided with escape pipe, described escape pipe is provided with check valve, and the escape pipe the other end is placed in described water tank; Ammonia water tank body bottom portion is provided with the first drain pipe, described first drain pipe is communicated with and is provided with Pump for giving-out and buffer tank, described buffer tank is provided with pressure transmitter, the signal output part of described pressure transmitter is electrically connected with the signal input part of the first PID controller, and the control output end of described first PID controller is electrically connected with the control input end of described Pump for giving-out; The liquid outlet of described buffer tank is connected with the fluid inlet of fermentation equipment by the second drain pipe, second drain pipe is provided with magnetic valve, described fermentation equipment is provided with pH meter probe, the signal output part of described pH meter probe is electrically connected with the signal input part of the second PID controller, the control output end of described second PID controller and the control input end control linkage of described magnetic valve.
The utility model advantage is that structure is simple, and cost is low, and dosage adds precisely, easy to use.When ammonia water tank internal gas pressure is low, vacuum breaker is opened, and air enters in tank from the inlet mouth at top; When ammonia water tank internal gas pressure height, check valve is opened, and gas is expelled in water tank from escape pipe, and the water in water tank absorbs, and environmental protection is pollution-free.
Accompanying drawing explanation
Fig. 1 is system schematic of the present utility model.
Embodiment
As shown in Figure 1, ammoniacal liquor automatic adding device described in the utility model, comprises ammonia water tank body 1; Described ammonia water tank body 1 side is provided with open-topped water tank 2, ammonia water tank body 1 top is provided with inlet mouth and air outlet, described inlet mouth is provided with vacuum breaker 3, be communicated with in described air outlet and be provided with escape pipe 4, described escape pipe 4 is provided with check valve 5, and escape pipe 4 the other end is placed in described water tank 2; The first drain pipe 6 is provided with bottom ammonia water tank body 1, described first drain pipe 6 is communicated with and is provided with Pump for giving-out 7 and buffer tank 8, described buffer tank 8 is provided with pressure transmitter 9, the signal output part of described pressure transmitter 9 is electrically connected with the signal input part of the first PID controller 10, and the control output end of described first PID controller 10 is electrically connected with the control input end of described Pump for giving-out 7; The liquid outlet of described buffer tank 8 is connected with the fluid inlet of fermentation equipment 12 by the second drain pipe 11, second drain pipe 11 is provided with magnetic valve 13, described fermentation equipment 12 is provided with pH meter probe 14, the signal output part of described pH meter probe 14 is electrically connected with the signal input part of the second PID controller 15, the described control output end of the second PID controller 15 and the control input end control linkage of described magnetic valve 13.
During use, according to the pH value that the pH meter probe 14 in fermentation equipment 12 records, the second PID controller 15 Controlling solenoid valve 13 carries out ammoniacal liquor interpolation; Ammonia water tank body 1 relies on check valve 5 and vacuum breaker 3 to maintain the atmospheric pressure state of ammonia water tank 1; Pump for giving-out 7, first PID controller 10, buffer tank 8 and pressure transmitter 9 maintain the pressure of relative equilibrium in the first drain pipe 6, ensure that the steady flow of ammoniacal liquor adds.Carried out the automatic control of potential of hydrogen by this device, greatly facilitate the operation in fermentation process.
