The method includes: resetting the actual minimum openness of the proportional valve according to the preset minimum openness of the proportional valve when the liquid level sensor detects that the actual material liquid level in the degassing tank reaches the preset upper limit to allow the actual minimum openness of the proportional valve to be not smaller than the preset minimum openness of the proportional valve; resetting the actual maximum openness of the proportional valve according to the preset maximum openness of the proportional valve when the liquid level sensor detects that the actual material liquid level in the degassing tank reaches the preset lower limit to allow the actual maximum openness of the proportional valve to be not larger than the preset maximum openness of the proportional valve. The method for controlling the liquid level in the degassing tank of the sterilization machine has the advantages that material liquid level fluctuation caused by foam in the degassing tank is effectively avoided by resetting the actual openness of the proportional valve, interference brought by the liquid level fluctuation is eliminated effectively, and the work stability of a degassing system is increased.
Description
Technical field
the present invention relates to beverage production technology field, the liquid level controlling method particularly in a kind of sterilization machine degassing tank.
Background technology
in beverage industry, most sterilization machine is configured with degas system, and wherein degas system plays and material is removed to bad smell, eliminated the effects such as solubility bubble.In process of production, owing to can produce a large amount of foams to during material degassing, when containing foam in degassing tank, along with the flowing of material, dense lather also can increase, and the liquid level that liquid level sensor detects raises; Now, the false liquid level signal of feed liquor proportioning valve detected by liquid level sensor, can slowly turn down to reduce inlet amount, even proportioning valve there will be the situation of cut out, and result in actual liquid inlet volume and be less than liquid outlet quantity, with the conveying of main pump, in degassing tank, foam can be taken out suddenly, causes liquid level sharply to diminish, at this moment proportioning valve has little time to regulate, liquid level in degassing tank can be caused too low, even occur that infusion pump is out of service, cause degas system fault.And when foam in degassing tank reduces suddenly or disappears, the liquid level signal of proportioning valve detected by liquid level sensor, opens to increase inlet amount rapidly, inlet amount is made to be greater than liquid outlet quantity, now proportioning valve has little time to regulate, and causes liquid level in degassing tank too high, affects degasifying effect.And conventional at present point position liquid level or PID Liquid level, uncontrollable this level fluctuation phenomenon, finally causes the invalid control of feed liquor, fluid instability.
Summary of the invention
the object of the invention is to solve the deficiencies in the prior art, liquid level controlling method in a kind of sterilization machine degassing tank is provided, by this control method, reduces the fluctuation of liquid level in degassing tank, improve the stability of degas system, effectively control the balance between material feeding amount and load.
for achieving the above object, the technical solution used in the present invention is: the liquid level controlling method in a kind of sterilization machine degassing tank, be provided with liquid level sensor in described degassing tank, the feed pipe of described degassing tank is also provided with the proportioning valve for regulating inlet amount, the method comprises:
the minimum aperture of default described proportioning valve when detecting according to described liquid level sensor the higher limit that the actual liquid level of material in described degassing tank reaches default, reset the minimum aperture of reality of described proportioning valve, make the minimum aperture of the minimum aperture of the reality of described proportioning valve>=default;
the maximum opening of default described proportioning valve when detecting according to described liquid level sensor the lower limit that the actual liquid level of material in described degassing tank reaches default, reset the actual maximum opening of described proportioning valve, make the maximum opening of the actual maximum opening of described proportioning valve≤default.
preferably, when the valve opening of described proportioning valve is adjusted to actual minimum aperture, the inlet amount in described degassing tank is not less than 75% of load.
preferably, when the valve opening of described proportioning valve is adjusted to actual maximum opening, the inlet amount in described degassing tank is not higher than 125% of load.
preferably, the valve opening of described proportioning valve regulates is programme controlled by PID by described liquid level sensor.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: the liquid level controlling method in sterilization machine degassing tank of the present invention, according to the actual liquid level of material in the degassing tank that liquid level sensor detects reach the default upper limit and lower in limited time, the default minimum aperture of proportioning valve and maximum opening, reset the actual maximum opening of proportioning valve and minimum aperture, by resetting minimum aperture and the maximum opening of proportioning valve, reduce the fluctuating range of liquid level in degassing tank, thus stopped liquid level sensor when there is because detecting in degassing tank false liquid level that foam causes, the generation of the liquid level phenomenon fluctuated causing proportioning valve mistake to regulate causing, and the phenomenon stopped because too low the caused infusion pump of degassing tank internal cause liquid level is stopped transport occurs.
Detailed description of the invention
below technical scheme of the present invention is further elaborated.
a liquid level controlling method in sterilization machine degassing tank, is provided with liquid level sensor in this degassing tank, and the feed pipe of degassing tank is also provided with the proportioning valve for regulating inlet amount.
in this example, the minimum aperture of default proportioning valve when detecting that the actual liquid level of material in degassing tank reaches default higher limit according to liquid level sensor, reset the minimum aperture of reality of proportioning valve, make the minimum aperture of the minimum aperture of the reality of proportioning valve>=default; When detecting that the actual liquid level of material in degassing tank reaches default lower limit according to liquid level sensor, the maximum opening of default proportioning valve, resets the actual maximum opening of proportioning valve, makes the maximum opening of the actual maximum opening of proportioning valve≤default.And the setting of the actual aperture of proportioning valve, need guarantee when the valve opening of proportioning valve is adjusted to actual minimum aperture, inlet amount in degassing tank is not less than 75% of load, when the valve opening of proportioning valve is adjusted to actual maximum opening, inlet amount in degassing tank not higher than 125% of load, to guarantee the stability of material liquid level in degassing tank.
in this example, the adjustment of proportioning valve valve opening is programme controlled by PID by liquid level sensor.
by the valve opening of proportioning valve reset, make when in degassing tank, foam increases, when the liquid level causing liquid level detector to detect is higher than actual liquid level, proportioning valve turns down gradually, during aperture minimum because of the reality reaching setting when the aperture of proportioning valve, the liquid inlet volume of material is not less than 75% of liquid outlet quantity, therefore, the liquid level in degassing tank can not be caused sharply to decline and cause infusion pump that unloaded phenomenon generation occurs, can not there is too large fluctuation in the liquid level in degassing tank.And when the foam in degassing tank reduces suddenly or disappears, the liquid level causing liquid level detector to detect declines suddenly, proportioning valve leaves greatly, because of when the aperture of proportioning valve reaches the actual maximum opening of setting, the liquid inlet volume of material is not more than 125% of liquid outlet quantity, makes the liquid level in degassing tank that the phenomenon sharply raised can not occur, thus there will not be because proportioning valve aperture is excessive, cause liquid level in degassing tank to exceed the upper limit, the situation causing degasifying effect to decline occurs.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
