Principle of work of the present utility model is as follows:

At first emulsion, hydrochloric acid are contained in respectively in two tank bodies before the work, and are placed on the same batching platform.By button the weight that emulsion, hydrochloric acid add in process of production at every turn is provided with respectively on integrated circuit U2, the control temperature of setting clear water on electric contact temp sensor ST1 is 70 ± 5 ℃.

Press clear water heating gauge tap SB3, when water temperature is lower than 70 ℃ in the clear water jar, 0 end of electric contact temp sensor ST1 and 1 termination are logical, A.C. contactor KM7 coil gets, three normally opened contact closures of A.C. contactor KM7, burner E1 gets, clear water in the burner E1 heating clear water jar, when the clear water temperature in the clear water jar reaches 70 ℃, 0 end of electric contact temp sensor ST1 and 1 end disconnect, 0 end and 2 terminations are logical, A.C. contactor KM7 coil losing electricity, three normally opened contacts of A.C. contactor KM7 disconnect, and burner E1 dead electricity stops to heat the clear water in the clear water jar, control the duty of burner E1 repeatedly, the clear water that makes clear water irritate interior remains on the constant temperature of setting.

When the clear water temperature arrives 70 ℃, press system start-up button SB1, integrated circuit U1 output electric signal earlier gets A.C. contactor KM5 coil, the normally opened contact of A.C. contactor KM5 is closed to be connected with motor circuit breaker Q M5 circuit, clarified water pump M5 running, simultaneously A whey tank water injecting electromagnetic valve DF2 is opened, the A whey tank is begun water filling, and A.C. contactor KM3 coil is got, the normally opened contact of A.C. contactor KM3 is closed to be connected with motor circuit breaker Q M3 circuit, 3 runnings of emulsionpump motor M, the A whey tank is begun to add emulsion, being installed in 4 the LOAD CELLS SP1～LOAD CELLS SP4s of batching around the platform converts the weight of emulsion and hydrochloric acid to electric signal and outputs to transmitter BP1, amplify through transmitter BP1, convert the normalized current signal of 4～20mA to, output to the A/D conversion input port of integrated circuit U1, integrated circuit U1 carries out this signal to draw the emulsion weight that reality has been added after the computing, compare with the setting emulsion interpolation value of integrated circuit U2 input, when the emulsion weight that detects interpolation reaches setting value, A.C. contactor KM3 disconnects, emulsion motor M 3 shuts down, and emulsion adds and finishes.

After emulsion adds end, integrated circuit U1 gets A.C. contactor KM4 coil, the normally opened contact of A.C. contactor KM4 is closed to be connected with motor circuit breaker Q M4 circuit, hydrochloric acid pump motor M4 running begins to add hydrochloric acid to the A whey tank, integrated circuit U1 draws the weight that reality has been added hydrochloric acid after handling as calculated according to the electric signal of LOAD CELLS SP1～LOAD CELLS SP4 output, compare with the setting hydrochloric acid interpolation value of integrated circuit U1 input, when the hydrochloric acid weight that detects interpolation reaches setting value, disconnect A.C. contactor KM4 immediately, hydrochloric acid pump motor M4 shuts down, and hydrochloric acid adds and finishes.

Water filling this moment is proceeded, and the whey liquid level reaches in limited time in the A whey tank when A whey tank upper limit liquid level sensor SL2 detects, and integrated circuit U1 makes A whey tank water injecting electromagnetic valve DF2 dead electricity, and the water filling of A whey tank finishes.Integrated circuit U1 output electric signal gets A.C. contactor KM1 coil, the normally opened contact of A.C. contactor KM1 is closed to be connected with motor circuit breaker Q M1 circuit, and A whey tank stirring motor M1 running is stirred after 5 minutes, A whey tank stirring motor M1 shuts down, and the whey batching finishes in the A whey tank.

Integrated circuit U1 control A whey tank drain solenoid valve DF1 opens then, A.C. contactor KM6 is got, the normally opened contact of A.C. contactor KM6 is closed to be connected with motor circuit breaker Q M6 circuit, whey pump M6 running, the whey that configures in the A whey tank enters the whey pipeline through A whey tank drain solenoid valve DF1, sends into the production that mulser carries out emulsified asphalt again.

When the A whey tank stirred beginning, integrated circuit U1 control B whey tank water injecting electromagnetic valve DF4 opened, and the water filling of B whey tank begins, and its principle of work and A whey tank principle of work are identical.It should be noted that: after the whey batching finishes in the B whey tank, if also discharging, the whey in the A whey tank do not finish, be that A whey tank bottom limit level sensor SL1 does not detect the arrival of whey liquid level down in limited time, B whey tank drain solenoid valve DF3 must not open, integrated circuit U1 control this moment A.C. contactor KM5 coil losing electricity, clarified water pump M5 shuts down.When A whey tank bottom limit level sensor SL1 detects whey discharging in the A whey tank and finishes, integrated circuit U1 control B whey tank drain solenoid valve DF3 opens, controlling A.C. contactor KM5 simultaneously gets, clarified water pump M5 running, A whey tank water injecting electromagnetic valve DF2 opens, and what the A whey tank was new one takes turns batching beginning.

In the time of need stopping to prepare burden, press the stop button SB2 of system.
