Description

Technical Field

[0001] The invention relates to the technical field of asphalt production equipment, and in particular to a production device for SBS modified asphalt. Background Art

[0002] With the rapid development of my country's national economy, the volume of highway traffic has increased rapidly, and road transportation has become increasingly busy. Although many highway asphalt pavements use traffic road asphalt or imported asphalt that meets the requirements, it still cannot meet the needs. The asphalt pavement has serious problems such as vehicle withdrawal, cracking, and potholes. In order to comprehensively improve the performance of asphalt pavements, the use of modified asphalt is one of the effective measures. The newly revised highway design specifications and asphalt pavement construction specifications both clearly require the comprehensive promotion of modified asphalt. Modified asphalt is basically used in the upper and middle layers of highway asphalt pavements. At present, the most commonly used modified asphalts are SBR, PE, EVA, rubber powder, SBS, etc., and SBS has been the most widely used in recent years because of its good two-way modification performance (that is, the ability to simultaneously change the high and low temperature properties of the base asphalt).

[0003] SBS modified asphalt is prepared using styrene-butadiene-styrene block copolymer as a modifier. Through the physical blending process, SBS absorbs aromatic hydrocarbons and colloids in the asphalt, causing swelling to form a new colloidal structure system, that is, forming a network structure in the asphalt, thereby comprehensively improving the performance of the asphalt.

[0004] The Chinese patent document with the announcement number CN207392003U discloses a modified asphalt production system, including a base asphalt storage tank, an asphalt heating tank, an asphalt mixing tank, a modifier conveying device, a colloid mill, an asphalt development tank, an asphalt finished product tank, etc. Among them, the colloid mill can refine the modified base asphalt to the micron level, so that the base asphalt and the SBS modifier are fully integrated in the asphalt development tank to form a stable and uniform mixture. However, due to the aging of the seals, the wear of the stator and the rotor, etc., the colloid mill will leak when used for a long time; and the existing production enterprises place a receiving tray under the colloid mill and use the receiving basin to receive the asphalt material leaked from the colloid mill.

[0005] However, when the asphalt material is accumulated in the receiving basin for a long time, the asphalt material will solidify due to the decrease in temperature. If the asphalt material needs to be recycled, the production staff needs to place the receiving basin on a heating device. Although this heating method can melt the asphalt material, a large amount of asphalt fume will be generated during the melting process of the asphalt material, which will cause great harm to the health of the production staff.

[0006] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0075] See also Figures 1 to 7 The present invention provides an SBS modified asphalt production device, including an asphalt mixing tank 1, a first colloid mill 2, a first material receiving assembly, a first delivery pipe 5 and a first asphalt pump 6. The first asphalt pump 6 is connected to the first delivery pipe 5. The first material receiving assembly includes a material receiving box 3, a material receiving plate 4, a smoke blocking plate 7 and a smoke exhaust pipe 8.

[0076] Specifically, a jacket is provided between the inner and outer walls of the asphalt mixing tank 1. Before production, the base asphalt in the base asphalt storage tank is transported to the asphalt mixing tank 1 through a pipeline (with the help of an asphalt pump), and the SBS modifier required for the modified asphalt is transported to the asphalt mixing tank 1 through a bucket elevator. In actual production, high-temperature heat transfer oil is introduced into the jacket, and under the stirring action of the asphalt mixing tank 1, the SBS modifier can be evenly dispersed in the molten base asphalt. The SBS can absorb aromatic hydrocarbons and colloids in the asphalt, swell, and form a new colloidal structure system, that is, a network structure is formed in the asphalt, so that the performance of the asphalt is comprehensively improved.

[0077] The first colloid mill 2 is connected to the asphalt mixing tank 1 through a pipeline, so that the base asphalt mixed with SBS modification can be transported to the first colloid mill 2 for grinding and shearing. The first material receiving assembly is arranged below the first colloid mill 2, and the first material receiving assembly includes a material receiving box 3, a material receiving plate 4, a smoke blocking plate 7 and a smoke exhaust pipe 8.

[0078] The receiving box 3 is arranged below the first colloid mill 2 to collect the asphalt material leaked from the first colloid mill 2; and the receiving plate 4 is arranged in the receiving box 3. When the receiving box 3 collects the asphalt material, the asphalt material is accumulated on the receiving plate 4. Furthermore, a heating interlayer 31 is formed between the receiving plate 4 and the inner bottom of the receiving box 3, and the bottom of the receiving plate 4 is connected to the aforementioned first conveying pipe 5. When the asphalt material collected by the receiving box 3 needs to be recycled, the heating interlayer 31 can be used to heat the asphalt material on the receiving plate 4, so that the asphalt material is melted, and the asphalt material can be pumped to the input end of the first colloid mill 2 through the first asphalt pump 6 and reused in the production of SBS modified asphalt.

[0079] When the heating interlayer 31 heats the asphalt material on the receiving plate 4, the smoke barrier 7 is covered on the top of the receiving box 3, thereby preventing the asphalt fume generated when the asphalt material is heated from leaking into the production workshop, which has little health hazards to production personnel. The exhaust pipe 8 is connected to the receiving box 3 (the connection is located above the receiving plate 4) and is connected to a fume treatment system, so the asphalt fume can be pumped into the fume treatment system for treatment, thereby reducing pollution to the atmospheric environment. The fume treatment system may include a spray tower, a cyclone separator, a fume incineration device, an activated carbon adsorption box, and an induced draft fan.

[0080] Optionally, the receiving plate 4 is arranged in a slanted downward direction in the receiving box 3, and the connection between the first conveying pipe 5 and the receiving plate 4 is located at the lower part of the receiving plate 4, so that when the asphalt material on the receiving plate 4 melts, the asphalt material can be more easily discharged into the first conveying pipe 5.

[0081] Optionally, the cross-section of the smoke barrier plate 7 in the vertical direction may be an inverted U-shape, and a sealing gasket may be attached to the inner wall of the smoke barrier plate 7. When the smoke barrier plate 7 is covered on the top of the material receiving box 3, the sealing gasket contacts the outer wall of the material receiving box 3 and the top surface of the material receiving box 3, thereby improving the sealing performance of the smoke barrier plate 7 to the material box 3, making it difficult for the asphalt fume in the material receiving box 3 to leak into the production workshop.

[0082] Optionally, a heating tube is detachably provided in the heating interlayer 31, or heat transfer oil is passed into the heating interlayer 31. When the heating tube is working, the heating efficiency of the heating tube is high, and the heat can be quickly transferred to the receiving plate 4, so that the asphalt material on the receiving plate 4 can be quickly melted. Heat transfer oil is a heating medium commonly used by asphalt production enterprises. When heat transfer oil is used as the heating medium to heat the asphalt material on the receiving plate 4, the outer box wall of the receiving box 3 is connected to a heat transfer oil circulation pipeline 36, and the heat transfer oil circulation pipeline 36 can be connected to a mold temperature controller or a heat transfer oil boiler, thereby ensuring a continuous supply of heat transfer oil in the heating interlayer 31.

[0083] like Figure 1 and Figure 5 As shown, optionally, the SBS modified asphalt production device further includes a filter 9, a second delivery pipe 10, a filter screen 11 and a top cover 12. The filter screen 11 is provided in the filter 9 to filter various impurities in the base asphalt and the SBS modifier, such as sand, gravel, dust, etc., thereby improving the purity of the SBS modified asphalt and preventing the asphalt delivery pipeline from being blocked.

[0084] Specifically, the filter 9 is arranged between the first asphalt pump 6 and the first colloid mill 2, and a feed port and a discharge port below the feed port are arranged on both sides of the filter 9. The filter 9 is arranged on the feed end of the first colloid mill 2, so that the mixture of the base asphalt and the SBS modifier can be filtered and then transported to the first colloid mill 2 for grinding and shearing, thereby preventing the rotor 203 and the stator 202 of the colloid mill from being seriously worn due to the introduction of impurities into the colloid mill, and thus improving the leakage of the colloid mill.

[0085] Specifically, the two ends of the second delivery pipe 10 are respectively connected to the output end of the first asphalt pump 6 and the feed port of the filter 9, and are used to connect the filter 9 and the first asphalt pump 6, so that the mixture of the base asphalt and the SBS modifier can be delivered to the filter 9 for filtration. The filter screen 11 is horizontally arranged in the filter 9, and the filter screen 11 is located between the feed port and the discharge port of the filter 9, thereby ensuring that the mixture of the base asphalt and the SBS modifier can fall on the filter screen 11, and thus be filtered through the filter screen 11.

[0086] Specifically, the top cover 12 is detachable (by means of a screw and a nut) and is disposed on the top of the filter 9, and a connecting rod 13 connected to the filter screen 11 is threadedly connected to the lower side of the top cover 12. When the top cover 12 is removed from the top of the filter 9, the connecting rod 13 can also move with the top cover 12. Therefore, after the top cover 12 is removed, the filter screen 11 connected to the connecting rod 13 can also be removed from the inside of the filter 9, thereby facilitating the production personnel to clean and replace the filter screen 11.

[0087] like Figure 1 and Figure 2 As shown, optionally, the SBS modified asphalt production device further includes a mixing chamber 14, a mixing mechanism 15 and a driving motor.

[0088] The feed end and the discharge end of the mixing chamber 14 are connected to the filter 9 and the first colloid mill 2 respectively, and an asphalt pump can be arranged between the feed end of the mixing chamber 14 and the filter 9 to ensure that the mixture of the base asphalt and the SBS modifier can be transported to the mixing chamber 14. The stirring mechanism 15 is rotatably arranged in the mixing chamber 14, and includes a stirring rod and a stirring blade arranged on the stirring rod. The stirring mechanism 15 can further stir the base asphalt so that the SBS modifier can be effectively dispersed in the base asphalt, thereby promoting the interaction and fusion of the SBS modifier and the base asphalt during the grinding and shearing process of the colloid mill, thereby improving the overall performance of the SBS modified asphalt.

[0089] The drive motor is arranged outside the mixing chamber 14, and the output shaft of the drive motor is in transmission connection with the mixing mechanism 15. The drive mechanism is used to drive the mixing mechanism 15 to rotate. In the present invention, the length direction of the output shaft of the drive motor is perpendicular to the direction in which the matrix asphalt enters and exits the mixing chamber 14, so that the drive motor is arranged outside the mixing chamber 14.

[0090] like Figure 1 and Figure 2 As shown, optionally, a first jacket 16 is provided between the inner wall and the outer wall of the mixing chamber 14, and heat transfer oil is passed into the first jacket 16. When the high-temperature heat transfer oil is passed into the first jacket 16, the heat carried by the heat transfer oil can be transferred to the mixing chamber 14, thereby ensuring that the base asphalt in the mixing chamber 14 is in a molten state, and while the base asphalt can be transported to the first colloid mill 2, it also ensures that the SBS modifier can be further dispersed in the base asphalt.

[0091] like Figure 1 and Figure 2 As shown, optionally, the SBS modified asphalt production device further includes a third delivery pipe 17 , a heat transfer oil inlet pipe 18 and a first oil delivery pipe 19 .

[0092] The two ends of the third delivery pipe 17 are respectively connected to the discharge end of the mixing chamber 14 and the feed end of the first colloid mill 2, and a second jacket 171 is provided between the inner and outer walls of the third delivery pipe 17. The heat transfer oil inlet pipe 18 is connected to the first jacket 16, and the heat transfer oil inlet pipe 18 can be connected to a heat transfer oil boiler, thereby enabling the heat transfer oil to be transported to the first jacket 16 for heating the matrix asphalt in the mixing chamber 14. The first oil delivery pipe 19 is simultaneously connected to the first jacket 16 and the second jacket 171, thereby enabling the heat transfer oil in the first jacket 16 to enter the second jacket 171.

[0093] When heat transfer oil is introduced into the second jacket 171 , the matrix asphalt mixture in the third delivery pipe 17 is in a molten state, so the matrix asphalt mixture can be smoothly delivered to the first colloid mill 2 without being blocked in the third delivery pipe 17 .

[0094] like Figure 1 and Figure 2 As shown, optionally, the first colloid mill 2 includes a grinding chamber 201; a stator 202 and a rotor 203 are arranged in the grinding chamber 201, and a third jacket 2011 is arranged between the inner wall and the outer wall of the grinding chamber 201. The SBS modified asphalt production device also includes a second oil pipeline 20 and a heat transfer oil outlet pipe 21. The second oil pipeline 20 is connected to the second jacket 171 and the third jacket 2011 at the same time; the heat transfer oil outlet pipe 21 is connected to the third jacket 2011, and the heat transfer oil outlet pipe 21 can be connected to the heat transfer oil boiler, so that the heat transfer oil can be circulated in the first jacket 16, the second jacket 171, the third jacket 2011 and the heat transfer oil boiler.

[0095] When the heat transfer oil enters the third jacket 2011, the heat carried by the heat transfer oil can be transferred to the grinding chamber 201 of the first colloid mill 2, so that the base asphalt mixture in the grinding chamber 201 can still remain in a molten state, making it easier to shear and homogenize the base asphalt mixture in the grinding chamber 201, thereby improving the production efficiency of SBS modified asphalt. When the base asphalt mixture has good fluidity, it helps to reduce blockage and wear in the colloid mill, so that the service life of the equipment can be extended.

[0096] like Figure 6 and Figure 7 As shown, optionally, the SBS modified asphalt production device further includes a second colloid mill 22 , a fourth conveying pipe 23 , a first valve body 24 and a second valve body 25 .

[0097] The second colloid mill 22 has the same structure as the first colloid mill 2 , and both include the grinding chamber 201 with the third jacket 2011 , a stator 202 and a rotor 203 disposed in the grinding chamber 201 , and the like.

[0098] The two ends of the fourth delivery pipe 23 are connected to the feed ends of the third delivery pipe 17 and the second colloid mill 22 respectively; the two ends of the fourth delivery pipe 23 are connected to the feed ends of the third delivery pipe 17 and the second colloid mill 22 respectively, a fourth jacket 231 is formed between the inner pipe wall and the outer pipe wall of the fourth delivery pipe 23, and the fourth jacket 231 can be connected to the first oil delivery pipe 19 through an oil delivery pipe; the first valve body 24 is arranged on the third delivery pipe 17, and the first valve body 24 is located downstream of the connection between the third delivery pipe 17 and the fourth delivery pipe 23; the second valve body 25 is arranged on the fourth delivery pipe 23. In actual production, one colloid mill can be kept running, and the present invention sets two colloid mills, the first colloid mill 2 and the second colloid mill 22, so that when one of the colloid mills needs maintenance, the other colloid mill can still be used normally, thereby ensuring that production can continue.

[0099] The first valve body 24 and the second valve body 25 are used to control whether the base asphalt mixture enters the colloid mill downstream of the first valve body 24 or the second valve body 25. Therefore, when one of the colloid mills needs maintenance, the corresponding valve body upstream of the colloid mill is closed, thereby preventing the base asphalt from being transported to the colloid mill that needs maintenance.

[0100] like Figure 6 As shown, optionally, the SBS modified asphalt production device further includes a second material receiving assembly 26, a fifth delivery pipe 27 and a third valve body 28. The second material receiving assembly 26 is arranged below the second colloid mill 22, and the structure of the second material receiving assembly 26 is the same as that of the first material receiving assembly, both of which include a material receiving box 3, a material receiving plate 4, a smoke blocking plate 7 and a smoke exhaust pipe 8. The two ends of the fifth delivery pipe 27 are respectively connected to the material receiving plate 4 of the second material receiving assembly 26 and the first delivery pipe 5; the third valve body 28 is arranged on the fifth delivery pipe 27.

[0101] When the second colloid mill 22 is activated, the second material receiving assembly 26 can be used to collect the asphalt material leaked from the second colloid mill 22; and the fifth delivery pipe 27 connected to the material receiving plate 4 of the second material receiving assembly 26 is connected to the first delivery pipe 5, so that when the third valve body 28 is opened, the asphalt material collected by the second material receiving assembly 26 can be pumped into the filter 9 through an asphalt pump (first asphalt pump 6).

[0102] like Figure 6As shown, in order to realize the switching use of the first colloid mill 2 and the second colloid mill 22, and to enable the base asphalt mixture ground and sheared by the switched colloid mill to be transported to the asphalt development tank 34, in an optional embodiment of the present invention, the SBS modified asphalt production device further includes a sixth delivery pipe 29, a seventh delivery pipe 30, a fourth valve body 31, a fifth valve body 32, a second asphalt pump 33 and an asphalt development tank 34. The sixth delivery pipe 29 is connected to the discharge end of the first colloid mill 2; one end of the seventh delivery pipe 30 is connected to the discharge end of the second colloid mill 22, and the remaining end of the seventh delivery pipe 30 is connected to the sixth delivery pipe 29; the fourth valve body 31 is arranged on the sixth delivery pipe 29, and the fourth valve body 31 is located upstream of the connection between the seventh delivery pipe 30 and the sixth delivery pipe 29; the fifth valve body 32 is arranged on the seventh delivery pipe 30; the feed end of the second asphalt pump 33 is connected to the sixth delivery pipe 29; and the asphalt development tank 34 is connected to the discharge end of the second asphalt pump 33.
