As shown in Figure 1, additive automatic feeding method provided by the invention, comprises the following steps:
S1: by the inflow needed for WPH operator setting allotment, allocate additive and stir in blend tank 1;
S2: by additive delivery to storage tank 2, and stir in storage tank 2;
S3: by the additive delivery in storage tank 2 to measuring tank 10;
S4: automatic program control discharging automatic valve 12 is opened, additive enters material metering tank 13 measuring tank 10.
First implementation step S1, by the inflow needed for WPH operator setting allotment, allocates additive and stirs in blend tank 1.
Flowmeter controls inflow, and in blend tank 1, add additive allocate, mixed by a certain amount of additive with water, the water yield required during allotment is measured by flowmeter.
Agitator stirs additive, is fully mixed additive by first conveyance conduit at the first filter 3, delivery pump 5, first valve 6, second valve 7 place.Add the additive in blend tank 1, by the impurity in the first filter 3 filtration additives, carried by delivery pump 5, manual unlocking first valve 6, second valve 7, additive in blend tank 1 is carried out the conveying circulated, agitator together stirs in addition, thus additive is mixed with water, and from even concentration under upper.
Then implementation step S2, by above-mentioned additive delivery to storage tank 2, and stirs in storage tank 2.
By second conveyance conduit at the first filter 3, delivery pump 5, first valve 6, the 3rd valve 8 place by additive delivery to storage tank 2, by agitator, the additive in storage tank 2 is stirred.Material by the first filter 3 impurity screening, by second conveyance conduit at delivery pump 5, first valve 6, the 3rd valve 8 place by additive delivery in storage tank 2, by the stirring action of agitator, additive is mixed in storage tank 2.
Then implementation step S3, by the additive delivery in storage tank 2 to measuring tank 10.
Additive in storage tank 2 passes through the second filter 4, the impurity in further filtration additives;
Additive delivery in storage tank 2 to measuring tank 10, quantitative weighing device sense weight pressure signal, when additive reaches setting value, automatic program control charging automatic valve 9 is closed; Otherwise timed reminding module is warned, after checking, additive reaches setting value, and automatic program control charging automatic valve 9 is closed.
Last implementation step S4, automatic program control discharging automatic valve 12 is opened, and additive enters material metering tank 13.
