Description

Technical Field

[0001] This invention belongs to the technical field of emulsified asphalt preparation, and particularly relates to an equipment, control method, and solid content detection method for emulsified asphalt preparation. Background Technology

[0002] Emulsified asphalt is an asphalt emulsion formed by dispersing viscous asphalt in water containing stabilizers in a droplet state through thermal melting and mechanical action. It is often used as an engineering material in road construction and maintenance. The general process of preparing emulsified asphalt includes: melting the base asphalt, then fusing it with the stabilizer, and feeding it into a mixing device to form finished emulsified asphalt through shear force.

[0003] The solid content of emulsified asphalt is a key indicator for measuring its quality, directly affecting construction results and costs. The solid content of emulsified asphalt is generally calculated by calculating the asphalt mass and stabilizer mass separately based on the asphalt flow rate and stabilizer flow rate. However, asphalt has a thermal expansion effect, meaning that the density of the same volume of hot asphalt will differ at different temperatures. Furthermore, this difference will vary depending on the type and composition of the asphalt, leading to a large error in the actual solid content and affecting construction quality. Summary of the Invention

[0004] The purpose of this invention is to provide equipment, control methods, and solid content detection methods for emulsified asphalt preparation, at least to solve the problem of inaccurate solid content detection in existing emulsified asphalt preparation processes, which affects construction quality. This purpose is achieved through the following technical solutions:

[0005] This invention proposes an emulsified asphalt preparation equipment, including a cold water tank, a hot water tank, a soap solution tank, a hot water pump, a soap solution pump, an asphalt pump, a mill, a finished product silo, and a control system;

[0006] The cold water tank supplies production water to the hot water tank;

[0007] The hot water tank is connected to the soap liquid tank via a hot water pump; the soap liquid tank is connected to the soap liquid pump, and the soap liquid pump is connected to the mill via a soap liquid delivery pipeline;

[0008] The asphalt pump is connected to the mill via an asphalt delivery pipeline and is used to pump the base asphalt into the mill.

[0009] The discharge end of the mill is connected to the finished product silo;

[0010] A first temperature sensor is installed on the soap solution conveying pipeline and the asphalt conveying pipeline respectively, and a second temperature sensor is installed at the discharge end of the mill.

[0011] In some embodiments, the discharge end of the mill is connected to a heat exchange chamber, and the discharge end of the heat exchange chamber is connected to a finished product silo.

[0012] In some embodiments, the heat exchange chamber is a double-layer shell structure, and the heat exchange chamber is connected to the external circulation loops of the cold water tank and the hot water tank respectively for discharging the required water into the heat exchange chamber.

[0013] In some embodiments, at least two soap dispensers are provided, and all of the soap dispensers alternately produce soap for the continuous preparation of emulsified asphalt.

[0014] The present invention also proposes a control method for the above-mentioned emulsified asphalt preparation apparatus, comprising the following methods:

[0015] The hot water pump starts to deliver hot water into the soap solution tank to produce soap solution. After the soap solution production is completed, the soap solution pump and the asphalt pump start at the same time to deliver the base asphalt and soap solution into the mill. After the milling process, the finished emulsified asphalt is formed.

[0016] During the production process, the control system intermittently detects the solid content of the emulsified asphalt according to a pre-set program. Based on the detected solid content in the finished emulsified asphalt, it adjusts the speed of the asphalt pump and the soap solution pump, controls the flow rate of the base asphalt and soap solution, and adjusts the solid content of the finished emulsified asphalt.

[0017] The present invention also provides a detection method for detecting the solid content of emulsified asphalt, including a flow rate detection method and a temperature balance detection method. The control system makes a comprehensive judgment based on the comparison of the data measured by the flow rate detection method and the temperature balance detection method, and adjusts the actual speed of the soap solution pump and the asphalt pump.

[0018] The flow detection method includes: the control system calculates the flow rates of the base asphalt and soap solution based on the rotational speeds of the asphalt pump and the soap solution pump, respectively, to obtain the mass of the base asphalt and soap solution passing through the mill within a certain time period. The solid content (ACP) is obtained by comparing the mass of the base asphalt with the total mass of the base asphalt and soap solution passing through the mill using the flow detection method. f ;

[0019] The temperature balance detection method includes: measuring the temperature of the base asphalt and soap solution before entering the mill using temperature sensors installed at the asphalt pump and soap solution pump; measuring the temperature of the produced emulsified asphalt using a temperature sensor at the mill discharge end; and obtaining the solid content (ACP) obtained by the temperature balance detection method using the following formula.

It also sets up a heat exchange chamber to cool or heat up the finished emulsified asphalt. This not only meets the needs of direct on-site preparation and immediate use, but also is suitable for plant mixing preparation and storage.

[0027] 2. In this invention, the soap solution and base asphalt are pumped into the mill by a soap solution pump and an asphalt pump, respectively. A first temperature sensor is installed at the discharge end of each of the soap solution pump and the asphalt pump, and a second temperature sensor is installed at the discharge end of the mill. The flow rate of the soap solution pump and the asphalt pump can be detected by calculating the solid content of the emulsified asphalt. The first and second temperature sensors measure the temperatures of the soap solution and base asphalt before they enter the mill and the temperature of the finished emulsified asphalt discharged from the mill, respectively. The solid content of the emulsified asphalt is calculated using a temperature balance detection method. By processing the solid content detected by the two methods using a weighted average method, the accuracy of the solid content of the emulsified asphalt detected during continuous production is improved. This facilitates dynamic adjustment of the soap solution and base asphalt, improves the quality of the finished emulsified asphalt, and ultimately ensures the quality of engineering construction.

[0036] Reference Appendix Figure 1In terms of overall design, this embodiment of the invention provides an emulsified asphalt preparation equipment, including a cold water tank 1, a hot water tank 2, a soap solution tank 3, a hot water pump 4, a soap solution pump 5, an asphalt pump 6, a mill 7, and a control system.

[0037] Cold water tank 1 supplies production water to hot water tank 2, and hot water tank 2 heats the incoming production water to the temperature required for making soap solution;

[0038] Hot water tank 2 is connected to soap liquid tank 3 via hot water pump 4. Soap liquid tank 3 is used to make soap liquid. Hot water pump 4 delivers water from hot water tank 2 that meets the temperature for making soap liquid to soap liquid tank 3. Soap liquid tank 3 is connected to soap liquid pump 5. Soap liquid pump 5 is connected to mill 7 via soap liquid delivery pipeline. That is, the made soap liquid is pumped into mill 7 by soap liquid pump 5.

[0039] Asphalt pump 6 is connected to mill 7 through asphalt conveying pipeline to send base asphalt pump 6 into mill 7. That is, mill 7 is used to react base asphalt and soap solution to produce emulsified asphalt. The discharge end of mill 7 is connected to finished product silo 8, and the produced emulsified asphalt will enter finished product silo 8.

[0040] A first temperature sensor is installed on the soap solution conveying pipeline and the asphalt conveying pipeline respectively, and a second temperature sensor is installed at the discharge end of the mill 7.

[0041] It is important to understand that during actual production, the base asphalt and soap solution continuously enter the mill 7, and the mill 7 continuously reacts the base asphalt and soap solution to form emulsified asphalt, which is then continuously discharged from the mill 7.

[0042] A first temperature sensor is installed on the soap solution conveying pipeline and the asphalt conveying pipeline respectively to detect the temperature of the base asphalt and soap solution before entering the mill 7. A second temperature sensor is installed at the discharge end of the mill 7 to detect the temperature of the emulsified asphalt discharged from the mill 7.

[0043] In some embodiments, in order to ensure continuous production of emulsified asphalt, the base asphalt and soap solution need to be continuously transported. To ensure the continuous transport of soap solution, at least two soap solution tanks 3 are provided. While one soap solution tank 3 is transporting soap solution, the other soap solution tank 3 quickly produces new soap solution for backup. When the soap solution in the previous soap solution tank 3 is about to run out, the new soap solution tank 3 continues to pump soap solution. That is, all soap solution tanks 3 alternately produce soap solution to ensure continuous production of emulsified asphalt.

[0044] In some embodiments, the produced emulsified asphalt can be stored directly and then transported to the construction site for use. There are also cases where the produced emulsified asphalt needs to be cleaned and used on-site. In such cases, the emulsified asphalt temperature may be too high or too low, making it unusable directly. To address this issue, the discharge end of the mill 7 is connected to a heat exchange chamber 9, and the discharge end of the heat exchange chamber 9 is connected to a finished product silo 8. This allows the emulsified asphalt produced from the mill 7 to be transported through pipelines to the heat exchange chamber 9. The system controls the temperature of the emulsified asphalt measured by the second temperature sensor and selects whether to cool or heat the emulsified asphalt in the heat exchange chamber 9 before discharging it into the finished product silo 8.

[0045] In some embodiments, the heat exchange chamber 9 has a double-layer shell structure. The heat exchange chamber 9 is connected to the cold water tank 1 and the hot water tank 2 respectively through external circulation loops to discharge the required water into the heat exchange chamber 9. That is, when the temperature of the emulsified asphalt discharged from the mill 7 is too high, the control system controls the cold water tank 1 to discharge cold water into the heat exchange chamber 9 to cool down the emulsified asphalt. When the temperature of the emulsified asphalt discharged from the mill 7 is too low, the control system controls the hot water tank 2 to discharge hot water into the heat exchange chamber 9 to heat up the emulsified asphalt.

[0046] The present invention also provides a control method for the above-mentioned emulsified asphalt preparation equipment, comprising the following method:

[0047] Hot water pump 4 starts to deliver hot water into soap liquid tank 3 to produce soap liquid. After the soap liquid production is completed, soap liquid pump 5 and asphalt pump 6 start at the same time to deliver base asphalt and soap liquid into mill 7. After being processed by mill 7, finished emulsified asphalt is formed.

[0048] The control system adjusts the speed of the asphalt pump 6 and the soap solution pump 5 according to the solid content detected in the finished emulsified asphalt, controls the flow rate of the base asphalt and soap solution, and adjusts the solid content of the finished emulsified asphalt.

[0049] In addition, the present invention also provides a detection method for detecting the solid content of emulsified asphalt, including: flow rate detection method and temperature balance detection method. The control system makes a comprehensive judgment based on the comparison of the data measured by the flow rate detection method and the temperature balance detection method, and adjusts the actual speed of soap solution pump 5 and asphalt pump 6.

[0050] It should be understood that in this invention, emulsified asphalt is produced continuously. Ensuring the quality of the produced emulsified asphalt will affect the quality of the construction project. Therefore, it is necessary to be able to detect the solid content of the emulsified asphalt in order to adjust the proportion of the base asphalt and ensure that the produced emulsified asphalt meets the requirements. In this embodiment, a combination of flow detection and temperature detection methods is used to detect the solid content of the emulsified asphalt.

[0051] In some embodiments, the flow detection method includes: the control system calculating the flow rates of the base asphalt and soap solution based on the rotational speeds of the asphalt pump 6 and the soap solution pump 5, respectively, to obtain the mass of the base asphalt and soap solution passing through the mill 7 within a certain time period, and obtaining the solid content (ACP) measured by the flow detection method by comparing the mass of the base asphalt with the total mass of the base asphalt and soap solution passing through the mill 7. f ;

[0052] It is important to understand that both the base asphalt and the soap solution are fluids. Their flow rates within pipes of the same diameter can be measured in the laboratory by setting the rotational speeds of the asphalt pump 6 and the soap solution pump 5. This yields a corresponding function, which, through the control system, drives the asphalt pump 6 and the soap solution pump 5, changing their flow rates. Once the flow rates are obtained, the mass of the base asphalt and soap solution can be calculated. This allows the control system to automatically select the voltage driving the asphalt pump 6 and the soap solution pump 5 after the solids content of the emulsified asphalt has been chosen, thus enabling the detection of the solids content (ACP) of the emulsified asphalt through flow rate. f ;

[0053] However, in actual use, due to temperature differences, the thermal expansion effect of the base asphalt causes changes in the actual flow rate, resulting in an error between the actual flow rate and the theoretical flow rate obtained from experiments. Therefore, in this embodiment, a temperature balance detection method is introduced to correct the flow rate detection method, thereby improving the detection accuracy of the solid content of emulsified asphalt in actual production, facilitating the adjustment of the flow rates of asphalt pump 6 and soap solution pump 5, and adjusting the solid content (ACP) of the emulsified asphalt. T ;

[0054] The temperature balance detection method includes: measuring the base asphalt temperature and soap solution temperature before entering the mill 7 using a first temperature sensor installed at asphalt pump 6 and soap solution pump 5; measuring the temperature of the produced emulsified asphalt using a second temperature sensor at the discharge end of mill 7; and obtaining the solids content (ACP) obtained by the temperature balance detection method according to the following formula. T :

[0055]

[0056]

[0057] Where: ET is the temperature of the finished emulsified asphalt before heat exchange; SOT is the soap solution temperature; MSO is the soap solution mass; CSO is the soap solution specific volume; ACT is the base asphalt temperature; K(T) is the base asphalt specific heat capacity; P m K is the output power of the mill shaft. m This is the shaft power coefficient obtained from the experiment.

[0058] It is important to understand that the linearity and zero drift of the asphalt temperature, soap solution temperature and finished product temperature (before heat exchange) sensors should be close to or consistent with those of the asphalt temperature, soap solution temperature and finished product temperature (before heat exchange). At the same time, the introduction of excess heat into the system should be eliminated. Therefore, when installing the temperature sensor, the insertion depth should be close to the center of the pipe to avoid introducing abnormal temperature into the system and affecting the accuracy of the temperature balance algorithm.

[0059] It is important to understand that when using the temperature balance algorithm to calculate solid content, it should be noted that the specific heat capacity of different grades of asphalt is approximately the same and the difference is not significant. However, the specific heat capacity of the same grade of asphalt varies slightly at different temperatures. Therefore, when calculating the energy released by the base asphalt, its specific heat capacity should be integrated over the range of temperature changes of the base asphalt to obtain more accurate results.

[0060] It is important to understand that the formula for calculating solid content in the temperature equilibrium detection method is obtained through the following process:

[0061] During the process of base asphalt and soap solution fusing together in mill 7 to form emulsified asphalt, if the work done by mill 7 is not considered, then the heat released by the base asphalt should be equal to the heat absorbed by the soap solution.

[0062] That is, the amount of heat released when a base asphalt with mass MAC and specific heat capacity K(T) decreases from its initial temperature ACT to its finished temperature ET: ;

[0063] A soap solution with mass MSO and specific heat capacity CSO absorbs heat released by the matrix bitumen as its temperature rises from SOT to ET. The amount of heat absorbed is: ;

[0064] Since QAC = QSO, therefore:

[0065] ;

[0066] The formula for calculating solid content is known to be: ;

[0067] Therefore, the solid content obtained by temperature equilibrium detection method is...

[0068] ;

[0069] However, in actual operation, when mill 7 is working, typically over 95% of the electrical energy is converted into heat energy through shear friction, turbulent heat generation, and work done to overcome viscosity resistance. This causes an increase in the temperature of the finished emulsified asphalt. This portion of electrical energy conversion also introduces excess heat into the system, and this heat cannot be effectively dissipated. Therefore, an additional power coefficient K is introduced for the emulsified asphalt mill 7. m Compensation is performed to eliminate the heat energy converted from electrical energy during the operation of mill 7, thereby increasing the accuracy of the temperature balance algorithm (temperature-based solid content).

[0070] That is, the heat absorbed by the soap solution is actually the sum of the heat radiated by the base bitumen and the energy of the work input by the mill 7. Therefore: QSO = QAC + W.

[0071] Therefore, for MAC, it is actually:

[0072] ;

[0073] Substituting MAC into the solids content calculation formula yields:

[0074]

[0075] In this embodiment, the energy W input to the mill 7 is equal to the output power of the mill 7 shaft. However, there will be an error between the actual output power of the mill 7 shaft and the calibrated power. Therefore, a power coefficient K for the mill 7 is introduced in this embodiment. m Therefore, compensation should be provided: .

[0076] In some embodiments, the final measured value of the solid content (ACP) of emulsified asphalt obtained from the flow rate detection method and the temperature equilibrium detection method is used. fixed :

[0077] ;

[0078] Among them, K t The solid content weight is determined by the temperature method.

[0079] It is important to understand that after obtaining the solid content from the flow rate detection method and the temperature equilibrium detection method, the data needs to be processed to improve the accuracy of the actual solid content. In this embodiment, a weighted average method is used to process the solid content measured by the flow rate detection method and the solid content measured by the temperature equilibrium detection method to obtain the final measured solid content value, where K... t The specific values ​​need to be optimized in experiments to improve the accuracy of continuous detection of emulsified asphalt solid content during construction and improve construction quality.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
