Third, the process
Asphalt (including heavy asphalt and modified asphalt) emulsification is basically: hot-melt state of the asphalt and emulsifier containing the proportion of the mixture by mixing, after the mechanical grinding of the emulsifier, the asphalt in a small particle state uniform Distributed in an aqueous solution containing an appropriate amount of emulsifier to form an oil-in-water emulsion, which is emulsified asphalt.
1, select the appropriate type of matrix asphalt (including heavy asphalt and modified asphalt), after dehydration, heating, filter debris and then pumped into the capacity of 3000 liters of asphalt thermostat, to maintain the appropriate temperature (recommended 130 ℃ -140 ° C).
2, preparation of emulsifier solution
The purified water was injected into a water heating tank and heated to 65 ° C to 70 ° C, and the mixture was injected into a 2000 L reactor by a blending pump. The selected emulsifier was added in an appropriate ratio (for example, an additive such as a stabilizer Can be added together) to the emulsifier mixing tank, stirring with water, and mixing with the mixing pump rolling rolling, and finally with the mixing pump into the reactor, add water to moderate proportion, heated to the appropriate temperature (recommended 65 ℃ -70 ° C), which is formulated as a standard emulsifier solution.
3, heating insulation
Open the pipe heat conduction heat conduction oil valve or turn on the power, all the asphalt through the parts (asphalt lines, asphalt pumps, valves, filters, etc.) heated to the appropriate temperature.
4, production
Open the asphalt pump, emulsifier solution pump, the asphalt, emulsifier aqueous solution at the same time into the colloid mill, that is, emulsified asphalt. The equipment of the oil (asphalt, emulsifier solution and diesel) ratio control is to use two excitation governor were controlled two excitation speed motor to adjust, according to "production, flow, proportion" three parameters on the two Transport motor speed, in order to achieve the required standards.
5, regulator
General asphalt emulsification can not adjust the normal working pressure of the emulsifier, but for the more difficult to emulsify the SBS modified asphalt, emulsifier should adjust the working pressure, generally should be maintained between 0.2-0.25Mpa, the best emulsifier effect.
Fourth, the operation adjustment
1, the water heating tank heating water, diesel tank to join the diesel;
2, asphalt transit tank into the asphalt;
3, open the water tank, asphalt transit tank heat transfer oil valve, pay attention to observation when heating water, asphalt temperature recommended 130 ℃ -140 ℃, water temperature between 65 ℃ -70 ℃.
4, to No. 1 (or No. 2) reactor water, heating;
5, open the pipeline insulation valve or connected to electric heating power, insulation lines;
6, mixed with the tank by adding appropriate amount of emulsifier;
7, to mix the tank with water to stir;
8, open the No. 1 (or 2) reactor, water three energy switch, start the emulsifier aqueous pump to the No. 1 (or No. 2) reactor with agitation stirrer mixing;
9, open the No. 1 (or No. 2) reactor stirrer to stir.
10, start asphalt pump, emulsifier solution pump, colloid mill and kerosene pump;
11, according to the asphalt, emulsifier and diesel ratio and productivity, to determine the matching speed of three pumps;
12, sampling test, measured on the screen remaining, adjust the colloid mill gap;
13, start the emulsified asphalt pump, the product emulsified asphalt transported to the emulsified asphalt storage tank;
14, in the production of emulsified asphalt at the same time, to the No. 2 reactor water, add emulsifier admixture, the preparation of emulsifier aqueous solution, after the use of No. 1 reactor, the conversion of three reactor 2 reactor in the emulsifier aqueous solution, While the preparation of No. 1 reactor in the solution, so the cycle;
15, the production process can continue to asphalt transit tank to add asphalt, while adjusting the heat transfer oil or electric heating pipe to ensure that the asphalt temperature within the set range;
16, the normal production will heat the pipeline heat transfer oil or electric heating to close, stop the pipeline heating.
Fifth, open, stop operation steps and precautions
1, boot operation steps:
(1) Open the emulsifier water solution tank valve while opening the asphalt tank valve.
(2) start the emulsifier aqueous solution gear pump, while starting the asphalt gear pump.
(3) start the emulsifier, while closing the emulsifier heat transfer oil.
2, the shutdown steps:
(1) stop asphalt gear pump;
(2) with the emulsifier aqueous solution after washing the pipeline, and then stop the emulsifier aqueous solution gear pump;
(3) to stop the emulsifier and pump;
(4) Disconnect the power supply.
3, Note:
(1) after the use of stirrer, should always check the oil standard;
(2) colloidal mill per 100 tons of emulsified asphalt plus butter once;
 
LR intelligent emulsified asphalt flow ratio meter operating instructions
1, the power cord plug into the AC 220-volt 50 Hz socket, where the center line connected to the chassis, should be a separate cable with a reliable access to the earth.
2, refer to the following figure, the input and output plugs and flowmeter, frequency converter corresponding to the corresponding terminal connection, pay attention to insulation, not short circuit. Pulse equivalent of two flow meters
Flow meter input socket

3, when the other system conditions (such as temperature, level, inverter, etc.) is ready, turn on the machine power, press the "0 / set" button in the "matrix asphalt flow" on the three LED digital display The preset asphalt flow is X. XX tons / hour. In the "emulsion flow" of the three LED digital tube shows the preset emulsion flow, with the X. XX tons / hour. The percentages of the ratio of pre-set bitumen to emulsion are shown on the three LED dies in the "Asphalt and Emulsion Ratio". The above data, stop power loss is not lost, can be permanently maintained, if you want to change, please enter the password and then reset. Confirm the above parameters correct, before starting to run.
4, in the "emulsified asphalt total output," the six LED digital tube shows the cumulative output of emulsified asphalt, for XXX. XXX tons. The data automatically after the start of the cumulative, stop power loss is not lost, the next run to continue to accumulate, for cleaning, please enter the password and press the "clear output" button.
5, to confirm the flow, the ratio of two parameters correct, press the "Run" button, the machine will control the two liquid pump quickly start, both fast and stable to achieve the default operating state, and in this state dynamic adjustment to To ensure that the emulsified asphalt products of high precision, high quality. In the whole process, press the "1 / work" button, the top three LED digital tube, the dynamic display of the actual substrate asphalt flow, emulsion flow and the proportion of asphalt and emulsion to the staff to reflect the entire system Of the running state.
6, the production is completed, be sure to press the "stop" button. At this point, the substrate asphalt pump immediately stop working, and the emulsion pump will continue to work for ten seconds, pay colloid mill in the viscous asphalt rinse, so that the next normal start. At the same time, this production will be accumulated to the total output.
7, parameter settings and clear the total output: press the "programming" button, all LED digital tube exterminate, this time, enter the password "168168", then "confirm" button, all LED digital tube and exterminate, so enter Set the state. Press the "Run" button, the two groups of LED digital tube shows the preset amount of emulsified asphalt (XX.X / hour) and asphalt and emulsion percentage (XXX%), re-enter the number, confirmed correct, Press "OK" to complete the parameter settings. In this state, if the "clear output" key, then the total output of emulsified asphalt cleared to zero. And then press the "programming" button, then out of the set state.
