The safe operation method of the plant-mixed hot recycling equipment for the asphalt mixture comprises the following specific steps:
under the normal operating condition: the cold material bin 1 sends cold reclaimed materials to the reclaimed material drying roller 2, the reclaimed material drying roller 2 heats and dries the cold reclaimed materials passing through the burner 21, and the hot reclaimed materials enter the metering device 5 for metering and then are sent into the stirring cylinder 2; the finished product valve 31 of the stirring cylinder 3 is in an open state, the waste valve 32 is in a closed state, and the hot recycled material is stirred by the stirring cylinder 3 and then sent out from the finished product valve 31.
Because the viscosity of the thermal regeneration material is high, in order to prevent the material from being stuck, the fuel injection device 6 injects diesel fuel to the position where the metering device 5 is easy to stick, and the flame detector cloth 7 is arranged at the position because the diesel fuel is inflammable. Waste gas generated in the reclaimed material drying roller 2 is sent out from the waste gas outlet 22, the fan 92 sends the waste gas into the waste gas pipeline 91, and the waste gas enters the combustor 21 through the waste gas pipeline 91 for combustion treatment or enters the primary equipment for treatment.
The temperature detection device 4 detects the temperature value in the reclaimed material drying roller 2 in real time and transmits the temperature value to the controller in real time; the flame detector 7 detects the working state information of the metering device 5 in real time and transmits the information to the controller; when the cold material valve 11 of the cold material bin 1 is in an open state, the material breakage detection device 8 detects the discharging state of the cold material valve 11 in real time and transmits the state information to the controller in real time; the controller stores preset values corresponding to the working state of the reclaimed material drying roller, wherein the normal working state in the roller corresponds to a normal value in the preset values, the ignition state in the roller corresponds to an upper limit value in the preset values, a critical state exists between the normal working state in the roller and the ignition state, the critical state corresponds to an alarm value in the preset values, the normal value is smaller than the alarm value and smaller than the upper limit value, and the controller compares the temperature value transmitted by the temperature detection device 4 with the preset values.
If the temperature value transmitted by the temperature detection device 4 is increased to an alarm value, the controller executes an alarm operation;
because the fire extinguishing operation depends on feeding of cold recycled materials, the working reliability of the cold storage bin 1 needs to be ensured, when the material breakage detection device 8 detects a material breakage signal, material breakage state information is sent to the controller, the controller executes vibration blockage removal operation, the vibration device 12 drives the cold storage bin 1 to vibrate for blockage removal, and the vibration is stopped when the controller does not receive the material breakage state information any more; the controller starts to execute vibration blockage removal operation and simultaneously performs timing operation, and when the timing is up to a first set time, the controller still receives the material failure state information, and then executes alarm operation; when timing to a second set time, the controller still receives the material cutting state information, and then the controller executes the fire reducing operation: reducing the operating power of the burner 21; wherein the first set time is less than the second set time;
wherein the alarm operation is: and (5) responding by using an audible and visual alarm.
If the temperature value transmitted by the temperature detection device rises to the upper limit value, the controller automatically executes the fire extinguishing operation: if the flame detector 7 detects that the metering device 5 catches fire, the controller automatically executes the fire extinguishing operation;
wherein the automatic fire extinguishing operation comprises the steps of closing the burner 21 and locking the state of the burner to be a starting prohibition state, fully opening the cold material valve 11, closing the oil spraying device 6, closing the waste gas valve 23 and the fan 92, closing the finished material valve 31 of the mixing tank and opening the waste material valve 32 of the mixing tank;
cold 1 of feed bin sends into a large amount of cold reclaimed materials toward regeneration drying roller 2, and cold reclaimed materials carries out rapid cooling and puts out to the department of catching fire to regeneration drying roller 2 when regeneration drying roller 2, and cold reclaimed materials puts out to the department of catching fire through 5 departments of metering device, and the final waste material valve of reclaimed materials discharges and abandons the nothing. The waste gas valve 23 and the fan 92 are closed to prevent waste gas from circulating in the reclaimed material drying roller 2 and prevent open fire from being introduced into primary equipment; when the temperature value transmitted by the temperature detection device 4 falls to a normal value, the controller unlocks the state of the burner 21.
The above-mentioned only be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
