Description

Technical Field

[0001] The invention relates to the technical field of asphalt pretreatment, in particular to an asphalt pretreatment process circulating solvent re-provision device and a use method thereof. Background Art

[0002] The solvent extraction-continuous sedimentation method removes quinoline insolubles from asphalt, using a mixture of kerosene and wash oil as the sedimentation solvent. The two oils are mixed in different mass ratios, and the sedimentation effect and sedimentation time of quinoline insolubles in asphalt are different. In production, an optimal mixing mass ratio must be found. In production, since the mixed solvent is recycled, solvent loss is inevitable during the circulation process: sometimes kerosene is lost, and sometimes wash oil is lost. Therefore, in continuous production, it is necessary to quickly determine the proportion of kerosene and wash oil in the recycled solvent in the mixed solvent, compare the actual ratio with the original ratio, and add fresh wash oil or kerosene after comparison. Only when the ratio of kerosene to wash oil in the circulating solvent is consistent with the original optimal ratio, can the circulating solvent after proportioning be used as the sedimentation solvent.

[0003] In daily production, the kerosene washing oil content in the circulating solvent is judged by liquid chromatography. The advantage is that it is more accurate, but it has the following disadvantages: First, it takes a long time to analyze the results and the efficiency is low. In daily production, each time a can of circulating solvent is recovered, it needs to be re-mixed with new solvent, so it is analyzed at least twice, and as many as three times or more. It takes at least one hour to analyze once with liquid chromatography, and the operation cycle of each can is as long as four hours. If the device is increased, the operation cycle is less than three hours. If it is analyzed three times or more, the chromatographic analysis results will not keep up with the on-site production, and it will not be possible to provide quick and effective guidance for production. Second, the instrument works for a long time. If it is not regularly maintained and inspected, the analysis results will be inaccurate, but production must be carried out continuously. In addition to regular annual maintenance, there is no time to spare for equipment maintenance for liquid chromatography. Summary of the invention

[0043] During the test, the support frame 331 supports and guides the plastic storage tube 61, preventing the plastic storage tube 61 from shaking. At the same time, the friction plate 334 is brought into contact with the outer wall of the plastic storage tube 61 through the electric control push rod 333. When not in use, the friction plate 334 is pressed against the outer wall of the plastic storage tube 61 by controlling the electric control push rod 333. At the same time, the plastic storage tube 61 can be clamped when reading the reading column 81, avoiding the plastic storage tube 61 from shaking and ensuring the accuracy of the reading. When the plastic storage tube 61 moves along the inner wall of the support frame 331, the rotating ball 338 will rotate along the outer wall of the plastic storage tube 61. The setting of the rotating ball 338 can increase the smoothness of the plastic storage tube 61 during the movement.

[0044] The receiving groove 335 serves the purpose of installation and storage, and the supporting spring 336 can move the mounting seat 337 disposed in the receiving groove 335 toward the direction close to the plastic receiving tube 61 , thereby ensuring that the rotating ball 338 can be in contact with the plastic receiving tube 61 .

[0045] Specifically, the adjustment component includes a threaded rod 8, which slides through the top of the side adjustment bracket 2. The outer wall of the threaded rod 8 is threadedly rotated with a threaded turntable 7. The lower end of the threaded rod 8 is fixedly connected to a reading column 81. A guide hole 62 is provided in the middle of the plastic storage tube 61, and the lower end of the reading column 81 is slidably inserted into the guide hole 62; scale lines are engraved on the outside of the reading column 81, and the lower end of the reading column 81 is fixedly connected to a stabilizing disk 811, which contacts the inner wall of the guide hole 62, and the stabilizing disk 811 is slidably connected to the inner wall of the guide hole 62, and the bottom of the stabilizing disk 811 is fixedly connected to a return spring 66, and the end of the return spring 66 away from the stabilizing disk 811 is fixedly connected to the bottom of the guide hole 62.

[0046] Rotating the threaded turntable 7 causes the threaded rod 8 to move downward. During the downward movement, the threaded rod 8 simultaneously drives the reading column 81 connected to the bottom and the plastic receiving tube 61 to move downward. During the downward movement of the plastic receiving tube 61, the test ball 64 will slowly enter the test cup 4. Before the test ball 64 contacts the circulating solvent, the top of the plastic receiving tube 61 is placed at the zero scale position of the reading column 81.

[0047] Specifically, a fixing plate 82 is fixedly connected to the top outer wall of the reading column 81, and a telescopic airbag 83 is fixedly connected to the lower surface of the fixing plate 82;

[0048] The top of the plastic storage tube 61 is fixedly connected with a sliding plate 84, and the sliding plate 84 can contact the bottom of the telescopic airbag 83. The middle of the support frame 3 is fixedly connected with an inner ring 31, and the outer wall of the inner ring 31 is provided with a plurality of limiting holes 32. The lower end of the telescopic airbag 83 is provided with a plurality of air pipes 85, and the lower end of the air pipe 85 passes through the sliding plate 84 and the limiting hole 32 and extends to the outside of the test ball 64.

[0049] After the detection is completed, the threaded turntable 7 is rotated in the opposite direction. At this time, the threaded rod 8 will move upward, and the test ball 64 will be driven to move upward and separate from the circulating solvent through the mounting rod 63. At this time, the sliding plate 81 can be pushed upward. The sliding plate 81 compresses the telescopic airbag 83 during the upward movement. The gas in the telescopic airbag 83 is blown toward the test ball 64 through the bottom of the air pipe 85, which can blow off the circulating solvent placed on the outer wall of the test ball 64, reducing the adhesion of the circulating solvent, which is beneficial to the cleaning of the test ball 64.

[0050] Specifically, a restraining belt 34 is provided inside the support frame 3, one end of the restraining belt 34 is fixedly connected to the inner wall of the support frame 3, and the other end of the restraining belt 34 is fixedly connected to the outer wall of the inner ring 31. A glass calibrated tube 5 is inserted between the restraining belt 34 and the inner ring 31, and a control valve 51 is fixedly installed at the bottom of the glass calibrated tube 5, and a conduit 52 is fixedly connected to the lower end of the control valve 51.

[0051] Kerosene and washing oil are stored in the glass graduated tube 5 and can flow into the test cup 4 from the conduit 52 by opening the control valve 51, and are added to the test cup 4. At the same time, the motor 65 is turned on to debug the circulating solvent sample placed in the test cup 4, and the circulating solvent in the entire asphalt pretreatment process is re-proportioned according to the proportion to ensure the accuracy of the re-proportioning process.

[0052] A method for using a circulating solvent re-mixing device in an asphalt pretreatment process comprises the following steps:

[0053] S1: Take out the circulating solvent and place it in the test cup (4), and then place the test cup (4) on the support plate (11);

[0054] S2: Control the test ball (64) to slowly enter the test cup (4), and stop when the test ball (64) enters half of the volume of the circulating solvent;

[0055] S3: Take readings and record the buoyancy F 浮 , the volume V of the test ball (64) 球 , according to formula F 浮 =ρV 排 g, where Conclusion

[0056] S4: After calculating the circulating solvent, the ratio of kerosene to wash oil in the circulating solvent is calculated using the formula y=-63.81ln(x)+896.81, the difference being that Y is 0.8747 g / cm3 to 0.9710 g / cm3; wherein X in the formula is the mass ratio of kerosene to wash oil, and Y is the density of the circulating solvent.

[0057] The density of the circulating solvent is measured, and then the ratio of kerosene to wash oil in the circulating solvent is calculated by the formula y=-63.81ln(x)+896.81, except that Y is 0.8747 g / cm3 to 0.9710 g / cm3. Other steps and parameters are the same as those in the first embodiment.

[0058] Specific implementation method three: This implementation method is different from the specific implementation method one in that the density of the circulating solvent is detected at 20° C. The other steps and parameters are the same as those of the specific implementation method one.

[0059] Experiment 1:

[0060] According to the mass ratio of kerosene (Haicheng Aohuan) to wash oil (Fushun Jisente) of 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95, 1.00, 1.05, 1.10, 1.15, 1.20, 1.25, 1.30, 1.35, 1.40, the mixed solvent was prepared. Under the condition of test temperature of 20℃, the density of kerosene and wash oil mixture was measured by density meter respectively. The relationship between the density of kerosene and wash oil mixture and the mass ratio of kerosene and wash oil is shown in Table 2:

[0061]

[0062]

[0063] like Figure 8 and Fig. 9 As shown, the curve is a logarithmic relationship, and the formula is y = -0.184ln (x) + 0.4247. As long as the mass ratio of kerosene to wash oil is between 0.50 and 1.50, the total aromatic content in the mixed oil measured by liquid chromatography can be used to obtain the ratio of kerosene to wash oil. According to this formula, the relationship between the mass ratio and any total aromatic content can be obtained, and a table can be made for the on-site operating workers. When the laboratory personnel measure the total aromatic content of the mixed solution, the production personnel can immediately obtain the mass ratio by looking up the table.

[0064] Working principle: First, take a sample of the circulating solvent and place it in the test cup 4. Before placing it in the test cup 4, calibrate the electronic weighing device 1. Then, start to rotate the threaded turntable 7 to make the threaded rod 8 move downward. During the downward movement, the threaded rod 8 simultaneously drives the reading column 81 connected to the bottom and the plastic storage tube 61 to move downward. During the downward movement of the plastic storage tube 61, the test ball 64 will slowly enter the test cup 4. Before the test ball 64 contacts the circulating solvent, the top of the plastic storage tube 61 is placed at the zero scale position of the reading column 81. When the plastic storage tube 61 slowly pushes the test ball 64 downward into the circulating solution in the test cup 4, under the buoyancy F 浮 Under the action of the plastic storage tube 61, a relative slide will occur between the plastic storage tube 61 and the reading column 81. The buoyancy of the test ball 64 at this time can be directly read through the reading line arranged on the outer wall of the reading column 81. 球 When the test ball 64 enters half of the circulating solvent, the rotation of the threaded turntable 7 is stopped. The volume of the test ball 64 entering the circulating solvent can be intuitively seen through the scale line on the outer wall of the test ball 64, which is convenient for the accuracy of the reading. According to the formula F 浮 =ρV 排 g, where Conclusion The density of the circulating solvent at this time can be calculated quickly and conveniently, which is convenient, fast and relatively accurate.

[0065] The outer wall of the test cup 4 is also provided with scale lines, and V can also be calculated by the scale of the liquid rising in the test cup 4. 球 , so that the data during the test is more accurate, and the weight M of the circulating solvent in the test cup 4 can also be measured by the electronic weighing device 1 剂 Then the circulating solvent is put into the test cup 4 and then it is left to stand for a while (part of the circulating solvent may adhere to the inner wall of the test cup 4 during the process of being poured into the test cup 4, resulting in the V reading of the test cup 4 being 剂 If the volume is too small, the calculated density will be too large, so the error can be reduced by leaving it still) Read the volume V 剂 , the density of the circulating solvent is By comparing the liquid density of the two sets of data, the accuracy of the calculation results is increased.

[0066] During the test, the support frame 331 supports and guides the plastic storage tube 61, preventing the plastic storage tube 61 from shaking. At the same time, the friction plate 334 is brought into contact with the outer wall of the plastic storage tube 61 through the electric control push rod 333. When not in use, the friction plate 334 is pressed against the outer wall of the plastic storage tube 61 by controlling the electric control push rod 333. At the same time, the plastic storage tube 61 can be clamped when reading the reading column 81, avoiding the plastic storage tube 61 from shaking and ensuring the accuracy of the reading. When the plastic storage tube 61 moves along the inner wall of the support frame 331, the rotating ball 338 will rotate along the outer wall of the plastic storage tube 61. The setting of the rotating ball 338 can increase the smoothness of the plastic storage tube 61 during the movement.

[0067] After the circulating solvent density test is completed, the ratio of kerosene to washing oil in the circulating solvent is calculated using the formula y=-63.81ln(x)+896.81. The kerosene and washing oil stored in the glass graduated tube 5 can flow from the conduit 52 into the test cup 4 by controlling the opening of the valve 51, and are added to the test cup 4. At the same time, the motor 65 is turned on to debug the circulating solvent sample placed in the test cup 4, and the circulating solvent in the entire asphalt pretreatment process is re-proportioned according to the ratio to ensure the accuracy of the re-proportioning process.

[0068] After the detection is completed, the threaded turntable 7 is rotated in the opposite direction. At this time, the threaded rod 8 will move upward, and the test ball 64 will be driven to move upward and separate from the circulating solvent through the mounting rod 63. At this time, the sliding plate 81 can be pushed upward. The sliding plate 81 compresses the telescopic airbag 83 during the upward movement. The gas in the telescopic airbag 83 is blown toward the test ball 64 through the bottom of the air pipe 85, which can blow off the circulating solvent placed on the outer wall of the test ball 64, reducing the adhesion of the circulating solvent, which is beneficial to the cleaning of the test ball 64.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
