Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.
As shown in fig. 1, the utility model provides a production device of emulsified asphalt, which comprises an emulsion stirring tank 1, a heat exchanger 2, a matrix asphalt storage tank 3, an emulsifying machine 4, an emulsified asphalt storage tank 5 and a heating coil 6 arranged in the heat exchanger 2.
Wherein the emulsion stirring tank 1 is used for preparing emulsion (soap solution) required for producing emulsified asphalt, and water required for preparing the emulsion is stored in the heat exchanger 2; after the emulsion is prepared, the emulsion can be transported to the emulsifying machine 4 by an emulsion transport pump 17. The heat exchanger 2 is connected with the emulsion stirring tank 1, and when water is needed, the water in the heat exchanger 2 can be conveyed into the emulsion stirring tank 1 through the water pump 21. The matrix asphalt storage tank stores matrix asphalt required for producing emulsified asphalt and other asphalt products, and the matrix asphalt can be conveyed into the emulsifying machine 4 under the action of the matrix asphalt conveying pump 18, and then is mixed with emulsion and ground to produce emulsified asphalt. The emulsified asphalt storage tank 5 is used for storing the produced emulsified asphalt.
Further, an interlayer 31 is arranged between the inner wall and the outer wall of the matrix asphalt storage tank 3. The emulsified asphalt production device further comprises a first conveying pipe 7, a second conveying pipe 8, a first discharge valve 9, a second discharge valve 10 and a third conveying pipe 20.
Wherein, one end of the first conveying pipe 7 is connected with the discharging end of the emulsifying machine 4, and the other end is connected with the inlet of the heating coil 6, so that when emulsified asphalt is produced, the emulsified asphalt can be conveyed (under the action of the emulsified asphalt conveying pump 19) into the heating coil 6 by the first conveying pipe 7, so that water in the heat exchanger 2 can be heated and then used for preparing emulsion.
Wherein the outlet of the heating coil 6 is connected with the emulsified asphalt storage tank 5, so that the emulsified asphalt can be conveyed to the emulsified asphalt storage tank 5 for storage after passing through the heating coil 6.
Wherein one end of the second conveying pipe 8 is connected with the first conveying pipe 7, and the other end is communicated with the interlayer 31, so that the produced emulsified asphalt can be conveyed into the interlayer 31 by the second conveying pipe 8. Because of the high temperatures at which emulsified asphalt is just produced, the heat contained in emulsified asphalt after it is transferred into interlayer 31 can be transferred into the matrix asphalt storage tank, so that the matrix asphalt can be kept warm, and the matrix asphalt can be conveniently transferred into emulsifying machine 4 or other production equipment through the pipeline.
Wherein one end of the third conveying pipe 20 is communicated with the interlayer 31, and the other end is connected with the emulsified asphalt storage tank 5, so that the emulsified asphalt in the interlayer 31 is finally conveyed (under the action of the emulsified asphalt conveying pump 19) to the emulsified asphalt storage tank 5 for storage.
Wherein the first discharge valve 9 is arranged on the first conveying pipe 7; the second discharge valve 10 is arranged on the second conveying pipe 8, so that the flow rate of the emulsified asphalt conveyed into the heating coil 6 and the interlayer 31 can be adjusted by controlling the valve opening of the first discharge valve 9 and the second discharge valve 10 respectively.
The utility model is characterized in that the interlayer 31 is arranged between the inner wall and the outer wall of the matrix asphalt storage tank, and the first conveying pipe 7 and the second conveying pipe 8 are arranged to convey the produced emulsified asphalt into the heat exchanger 2 and the interlayer 31 respectively, so that the heat generated by the emulsified asphalt can be recovered, and the recovered heat is used for carrying out heat preservation on the matrix asphalt and heating hot water required by emulsion configuration. Because the asphalt production enterprises use large amounts of matrix asphalt and need to use the matrix asphalt for a long time, when the temperature of hot water in the heat exchanger 2 meets the requirement for preparing emulsion, the recovered heat can be used for preserving the heat of the matrix asphalt, so that the energy consumption of the matrix asphalt during operation of the matrix asphalt storage tank can be reduced, and the heat generated by the emulsified asphalt can be fully utilized after recovery.
In addition, by arranging the first discharge valve 9 and the second discharge valve 10 on the first conveying pipe 7 and the second conveying pipe 8 respectively, when the temperature of the hot water in the heat exchanger 2 meets the requirement of preparing emulsion, the produced emulsified asphalt can be completely conveyed into the interlayer 31 by controlling the valve opening of the two discharge valves, so that the heat recovered is only used for insulating the matrix asphalt; when the temperature of the hot water in the heat exchanger 2 is less than the required value for preparing the emulsion, the valve opening of the two discharge valves can be controlled to increase the flow rate of the emulsified asphalt conveyed into the heating coil 6, so that more heat is recovered for heating the water until the temperature in the heat exchanger 2 is recovered again to the required value for preparing the emulsion, and the recovered heat is only used for preserving the matrix asphalt.
As shown in fig. 1, it is preferable that the third transfer pipe 20 is connected to the interlayer 31 at the upper portion of the matrix asphalt storage tank, and the second transfer pipe 8 is connected to the interlayer 31 at the lower portion of the matrix asphalt storage tank, so that the emulsified asphalt has a longer transfer flow time in the interlayer 31, and thus, as much heat generated from the emulsified asphalt as possible is transferred to the inside of the matrix asphalt storage tank.
As shown in fig. 1 and 2, in one embodiment, the emulsified asphalt production apparatus further includes a first thermometer 11; the first thermometer 11 is used for monitoring the temperature of the hot water in the heat exchanger 2, so that an operator can observe the temperature of the hot water in the heat exchanger 2 conveniently. When the temperature of the hot water in the heat exchanger 2 is lower than the required requirement for the emulsion configuration, the operator can know and adjust the valve opening of the first discharge valve 9 and the second discharge valve 10 respectively in time.
In one embodiment, the emulsified asphalt production device further comprises a controller; the controller is electrically connected with the first thermometer 11, the first discharge valve 9 and the second discharge valve 10 at the same time. In this embodiment, the first discharge valve 9 and the second discharge valve 10 may be electric valves. The hot water temperature value required for the emulsion configuration can be preset by the controller. In the specific implementation, the temperature value actually monitored by the first thermometer 11 can be fed back to the controller, and when the first thermometer 11 monitors that the temperature of the hot water in the heat exchanger 2 is lower than the preset hot water temperature value, the controller can automatically adjust the valve opening of the first discharge valve 9 and the valve opening of the second discharge valve 10, so that manual operation is not needed, and the degree of automation is higher.
As shown in fig. 2, it is preferable that the first thermometer 11 is provided at the lower portion of the heat exchanger 2, so that it is possible to ensure that the first thermometer 11 monitors the temperature of the hot water even if the water level in the heat exchanger 2 is low.
Preferably, the hot water temperature value may include a low temperature value and a high temperature value, and the temperature range formed by the low temperature value and the high temperature value is an adaptive temperature range of hot water required for configuring the emulsion, so that when the temperature value actually monitored by the first thermometer 11 is lower than the low temperature value, the valve opening of the first discharge valve 9 and the second discharge valve 10 are dynamically adjusted, and after the temperature of the hot water is raised to the high temperature value, the first discharge valve 9 is in a closed state, so that the recovered heat is only used for preserving the matrix asphalt. By adopting this preferred embodiment, after the hot water temperature of the heat exchanger 2 reaches the required requirements for the emulsion to be prepared, the hot water in the heat exchanger 2 can meet the use requirements for a long time even without feeding emulsified asphalt to the heating coil 6.
In one embodiment, as shown in fig. 2, the emulsified asphalt production apparatus further comprises a water inlet pipe 12 and a flow meter 13. The water inlet pipe 12 is connected with the heat exchanger 2, and the flowmeter 13 is arranged on the water inlet pipe 12. When water needs to be added into the heat exchanger 2, the water adding amount can be judged by the flow meter 13, so that the water adding amount (water consumption) can be conveniently adjusted based on the configuration requirement of the emulsion.
In one embodiment, as shown in fig. 2, the emulsified asphalt production apparatus further comprises a water inlet control valve 14; the flowmeter 13 is an electronic turbine flowmeter; the water inlet control valve 14 is arranged on the water inlet pipe 12, and the water inlet control valve 14 and the electronic turbine flowmeter are electrically connected with the controller, so that the electronic turbine flowmeter can monitor the water adding amount and feed back the monitoring result to the controller, and the water adding amount of the heat exchanger 2 can be automatically adjusted through the controller without manual operation.
As shown in fig. 3, in one embodiment, the bottom of the matrix asphalt storage tank is provided with a heating layer 32; the heating layer 32 is used to heat the base asphalt to ensure that the base asphalt is in a heat-insulating state.
In one embodiment, as shown in fig. 3, the heat conducting oil is circularly injected into the heating layer 32, and the heat of the heat conducting oil is transferred to the matrix asphalt in the tank above the heating layer 32, so that the matrix asphalt is kept in a heat-preserving state.
As shown in fig. 4, in one embodiment, a plurality of electric heating rods 15 may be disposed within the heating layer 32. The heat generated by the operation of the electric heating rod 15 can also keep the matrix asphalt in the tank in a heated and heat-insulating state. Further, the emulsified asphalt production device also comprises a second thermometer 16; the second thermometer 16 is used for monitoring the temperature in the matrix asphalt storage tank, and the second thermometer 16 is electrically connected with the controller, so that the heating power of the electric heating rod 15 can be adjusted by dynamically monitoring the temperature in the matrix asphalt storage tank, and the situation of excessive temperature rise and energy waste of the matrix asphalt is avoided.
