Description

TECHNICAL FIELD

[0001] The application relates to the technical field of asphalt production and heat preservation, in particular to a heating and heat-preserving device and a mobile modified rubber asphalt production equipment. BACKGROUND

[0002] Modified rubber asphalt is a high-performance pavement material formed by adding waste tire rubber powder to base asphalt through special process.

[0035] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0038] The following description, with reference to the accompanying drawings, describes a heating and insulation device and a mobile modified rubber asphalt production equipment according to embodiments of this application.

[0039] Please see Figure 1 and Figure 2A heating and heat preservation device according to an embodiment of this application includes: a storage tank 1 and a flipping heat conduction mechanism 2.

[0040] A feeding port 11 is provided at the top of the storage tank 1, and a discharge pipe 12 is provided at the bottom of the storage tank 1. A discharge valve is installed on the discharge pipe 12. The tilting heat conduction mechanism 2 includes a tube rod 21, a rotation drive assembly 22, an oil inlet assembly 23, an oil return assembly 24, a front coil 25, and a rear coil 26. The tube rod 21 is rotatably arranged through the axis of the storage tank 1. The tube rod 21 includes an end shaft 216, a front tube 211, a front shaft 214, a middle tube 213, a rear shaft 215, and a rear tube 212 connected axially in sequence. The rotation drive assembly 22 is installed at the end of the storage tank 1 to drive the end shaft 216 to rotate. Oil inlet assembly 23 and oil return assembly 24 are respectively installed at both ends of storage tank 1. Oil inlet assembly 23 is rotatably connected to front tube 211, and oil return assembly 24 is rotatably connected to rear tube 212. Two sets of front coils 25 are symmetrically arranged on both sides of front shaft 214. The oil inlet port of front coil 25 is connected to front tube 211, and the oil outlet port of front coil 25 is connected to middle tube 213. Two sets of rear coils 26 are symmetrically arranged on both sides of rear shaft 215. The oil inlet port of rear coil 26 is connected to middle tube 213, and the oil outlet port of rear coil 26 is connected to rear tube 212.

[0041] The heat transfer oil circulation heating system (not shown) in the modified rubber asphalt production equipment introduces heat transfer oil into the oil inlet assembly 23. The heat transfer oil from the oil inlet assembly 23 enters the front tube 211 of the tube member 21. The heat transfer oil entering the front tube 211 then passes through two sets of front coils 25 for heat transfer. The oil inside the front coils 25 finally enters the middle tube 213, and then enters the rear coil 26. The heat transfer oil inside the rear coil 26 finally flows into the rear tube 212, and finally returns to the heat transfer oil circulation heating system through the discharge pipe 12. When the heat transfer oil enters the front coils 25 and the rear coil 26, the heat from the heat transfer oil inside the front coils 25 and the rear coil 26 is transferred to the asphalt oil inside the storage tank 1. During the heat transfer process, the rotation drive assembly 22 rotates the drive end shaft 216, which in turn drives the front coil 25 outside the front shaft 214 and the rear coil 26 outside the rear shaft 215 to rotate. The rotation of the front coil 25 and the rear coil 26 expands the heating area inside the storage tank 1. At the same time, the rotating front coil 25 and the rear coil 26 will also stir the asphalt oil stored inside.

[0042] Compared to traditional asphalt insulation storage tanks, this heating and insulation device places the front coil 25 and rear coil 26 in the middle of the storage tank 1. Compared to the traditional method of placing the coils on the inner bottom side, this provides a larger contact area. The rotating front coil 25 and rear coil 26 further increase the heat conduction area. At the same time, the front coil 25 and rear coil 26 can agitate the asphalt oil inside the storage tank 1, making the viscous asphalt oil inside the storage tank 1 heat up more evenly. This improves the uniformity of mixing between the internal rubber powder and asphalt oil, reduces the precipitation of rubber powder, and reduces the occurrence of asphalt lumps in local areas inside the storage tank 1.

[0043] In the above specific implementation method, please refer to Figure 3 The oil inlet assembly 23 includes an oil inlet shell 231 and an oil inlet pipe 232. The oil inlet shell 231 is fixed to one end of the storage tank 1. The front tube 211 rotatably passes through the oil inlet shell 231. An oil inlet port I 2111 is provided on the outside of the front tube 211, located inside the oil inlet shell 231. An oil outlet port I 2112 is provided on the outside of the front tube 211, communicating and cooperating with the oil inlet port of the front coil 25. The heat transfer oil heated in the heat transfer oil circulation heating system enters the interior of the oil inlet shell 231 through the oil inlet pipe 232. The heat transfer oil inside the oil inlet shell 231 enters the front tube 211 through the oil inlet port I 2111, and then enters the front coil 25 through the oil outlet port I 2112. The front tube 211 and the oil inlet shell 231 are rotatably connected, and a sealing structure is provided between the rotating parts to prevent oil leakage.

[0044] For details, please refer to Figure 4 and Figure 5The oil return assembly 24 includes an oil return shell 241 and an oil return pipe 242. The oil return shell 241 is fixed to the other end of the storage tank 1. The rear tube 212 rotates through the oil return shell 241. An oil outlet III 2122 located inside the oil return shell 241 is provided on the outside of the rear tube 212, and an oil inlet III 2121 connected to the oil outlet port of the rear coil 26 is provided on the outside of the rear tube 212. An oil inlet II 2131 and an oil outlet II 2132 are respectively provided on the outer wall of the middle tube 213. The oil outlet port of the front coil 25 is connected to the oil inlet II 2131, and the oil inlet port of the rear coil 26 is connected to the oil outlet II 2132. The oil inside the front coil 25 finally enters the middle tube 213 through the oil inlet II 2131, and then enters the rear coil 26 through the oil outlet II 2132 on the middle tube 213. The oil inside the rear coil 26 finally enters the rear tube 212 through the oil inlet III 2121. The oil inside the rear tube 212 then enters the return oil shell 241 through the oil outlet III 2122, and flows back to the heat transfer oil circulation heating system for reheating via the return oil pipe 242. The rear tube 212 and the return oil shell 241 are rotatably mounted, and a sealing structure is provided between them to prevent heat transfer oil leakage. The sealing mechanism described in this technical solution can be any sealing structure known to those skilled in the art, and will not be elaborated further.

[0045] Furthermore, flange I 233 is installed at the end of the oil inlet pipe 232, and flange II 243 is installed at the end of the oil return pipe 242. Both flange I 233 at the end of the oil inlet pipe 232 and flange II 243 at the end of the oil return pipe 242 are designed to be detachable from the mobile equipment, facilitating disassembly, assembly, and relocation between different equipment systems.

[0046] For specific settings, please refer to Figure 6 The rotation drive assembly 22 includes a motor 221, a drive sprocket 222, a driven sprocket 223, and a chain 224. The driven sprocket 223 is fixedly sleeved on the outside of the end shaft 216, the drive sprocket 222 is fixedly sleeved on the output shaft end of the motor 221, and the chain 224 connects the drive sprocket 222 and the driven sprocket 223. The output shaft end of the motor 221 in the rotation drive assembly 22 drives the drive sprocket 222 to rotate, and the cooperation between the driven sprocket 223 and the chain 224 drives the end shaft 216 to rotate.

[0047] Furthermore, the flipping heat conduction mechanism 2 also includes a protective cover 27, which covers the outside of the rotation drive assembly 22 and is fixedly connected to the end wall of the storage tank 1 by bolts. The protective cover 27 is provided to protect the rotation drive assembly 22 and the end shaft 216, and the oil inlet pipe 232 is provided through the protective cover 27.

[0048] The heating and insulation device also includes an external fixing frame 3, which is fixedly installed on the outside of the storage tank 1. A sleeve 13 is fixedly fitted onto the outside of the storage tank 1, and the outer side of the sleeve 13 is fixedly connected to the inner wall of the external fixing frame 3 via a support rod 14. The sleeve 13 and the support rod 14 provide support and reinforcement. The external fixing frame 3 serves two purposes: protecting the storage tank 1 and facilitating the overall lifting and transfer of the storage tank 1.

[0049] When the rotation drive assembly 22 in the above-mentioned heating and heat preservation device drives the tube rod 21 to rotate the front coil 25 and the rear coil 26, the front coil 25 and the rear coil 26 are tubular structures, and the disturbance amplitude and range of the asphalt oil inside the storage tank 1 are relatively small.

[0050] Please see Figure 7 and Figure 8 This application provides another embodiment where the heating and heat preservation device further includes an oil temperature heat conduction auxiliary mechanism 4. Multiple sets of oil temperature heat conduction auxiliary mechanisms 4 are equidistantly installed on the symmetrically arranged front coil 25 and rear coil 26. Each oil temperature heat conduction auxiliary mechanism 4 includes an outer ring 41, heat conduction strip I 42, heat conduction strip II 44, and a heat conduction diversion assembly 47. Heat conduction strip I 42 and heat conduction strip II 44 are integrally formed in a cross shape. The outer ring 41 is sleeved and connected to the outer edges of heat conduction strip I 42 and heat conduction strip II 44. The side of heat conduction strip I 42 has mounting holes 43 that penetrate and engage with the front coil 25 and rear coil 26. Heat conduction strip II 44 has two sets of grooves II 46 and two sets of grooves I 45, symmetrically arranged at both ends. The heat conduction diversion assembly 47 is slidably engaged along grooves II 46 and grooves I 45.

[0051] The drive shaft 216 of the rotation drive assembly 22 drives the entire tube rod 21 to rotate. The rotating tube rod 21 will cause the front coil 25 and rear coil 26, which are connected to its outer side, to rotate together. The hot oil flowing inside the front coil 25 and rear coil 26 conducts heat to the liquid asphalt inside the storage tank 1. The rotation of the front coil 25 and rear coil 26 can increase the heat conduction area of ​​the front coil 25 and rear coil 26, thereby improving the overall heating uniformity of the liquid asphalt stored inside the storage tank 1. At the same time as the front coil 25 and rear coil 26 rotate, the oil temperature heat conduction auxiliary mechanism 4 installed on the front coil 25 and rear coil 26 will also rotate together. The heat conduction strip I 42, heat conduction strip II 44, and outer ring 41 in the oil temperature heat conduction auxiliary mechanism 4 are all made of materials with good thermal conductivity, which can more efficiently transfer the heat from the front coil 25 and rear coil 26 to the liquid asphalt inside the storage tank 1. Meanwhile, the outer ring 41 is set on the outer edge of the heat-conducting strip plate I 42 and the heat-conducting strip plate II 44 to form an integrated fixed structure, which improves the overall stability of the support structure of the heat-conducting strip plate I 42 and the heat-conducting strip plate II 44.

[0052] As the current coil 25 and the rear coil 26 drive the heat-conducting plates I 42 and II 44 to rotate slowly, the heat-conducting diversion assembly 47, which is slidably fitted with the heat-conducting plate II 44, also agitates the liquid asphalt inside the storage tank 1, increasing the agitation amplitude and allowing the liquid asphalt inside the storage tank 1 to be heated more quickly and evenly. Since the heat-conducting diversion assembly 47 is slidably fitted with the grooves I 45 and II 46 on the heat-conducting plate II 44, as the heat-conducting plate II 44 drives the heat-conducting diversion assembly 47 to rotate slowly, the heat-conducting diversion assembly 47 will move towards the lower groove I 45 or groove II 46 under its own gravity. After groove I 45 or groove II 46 rotates to a vertical position, within a further 30° rotation, the heat-conducting diversion component 47 is kept at the bottom. The movement of the heat-conducting diversion component 47 is synchronized with the rotation of the heat-conducting plate II 44, with the component continuously moving and changing along groove I 45 and groove II 46. That is, when the front coil 25 and rear coil 26 drive the heat-conducting plates I 42 and II 44 to rotate, the rotating heat-conducting diversion component 47 does not rotate around the axis of the tube rod 21, but rather rotates offset around the axis. This rotation of the heat-conducting diversion component 47 causes the liquid asphalt at different heights inside the storage tank 1 to be agitated, resulting in a better mixing effect compared to rotating around the axis.

[0053] The heat transfer oil of the aforementioned heating and insulation device first passes through the front coil 25 and then through the rear coil 26, resulting in the temperature of the heat transfer oil in the rear coil 26 being lower than that in the front coil 25. This causes the temperature of the liquid asphalt inside the storage tank 1 near the rear coil 26 to be lower than that near the front coil 25, resulting in an uneven temperature of the liquid asphalt inside the storage tank 1.

[0054] Please see Figure 8 and Figure 9The heating and insulation device also includes an inner tank shell 5 and a pad 51. The inner tank shell 5 is located inside the storage tank 1, and a flow guiding cavity layer is left between the inner tank shell 5 and the inner wall of the storage tank 1. The pad 51 is located inside the flow guiding cavity layer and connects the inner tank shell 5 and the storage tank 1. The heat conduction and diversion assembly 47 includes a limiting bracket 471, a flow guiding blade I 472, and a flow guiding blade II 473. The two sets of limiting brackets 471 are arranged in parallel, and the two flow guiding blades I 472 and flow guiding blade II 473 are respectively arranged in an inclined annular array at both ends of the limiting bracket 471. The limiting bracket 471 includes a U-shaped connecting rod I 4711, a U-shaped connecting rod II 4712, a connecting block 4713, a limiting block I 4714, and a limiting block II 4715. Connecting block 4713 connects connecting rod I 4711 and connecting rod II 4712. Connecting rod I 4711 slides through groove I 45, and connecting rod II 4712 slides through groove II 46. Limiting block II 4715 is fixed to the outside of connecting rod II 4712, limiting connecting rod II 4712 to slide along groove II 46. Limiting block I 4714 is fixed to the outside of connecting rod I 4711, limiting connecting rod I 4711 to slide along groove I 45. Limiting blocks II 4715 and I 4714 are located on both sides of heat-conducting strip II 44.

[0055] The guide vanes I 472 and II 473 at both ends of the limiting bracket 471 are inclined. When the rotating heat-conducting strip II 44 drives the limiting bracket 471, guide vanes I 472 and II 473 to rotate, the arrangement of guide vanes I 472 and II 473 can increase the overall turbulence area and improve the mixing effect of liquid asphalt inside the storage tank 1.

[0056] As the limiting bracket 471 drives the guide vanes I 472 and II 473 to rotate, the rotating guide vanes I 472 and II 473 will also drive the liquid asphalt inside the inner liner 5 to slowly move along the axial direction towards the end closer to the rear tube 212. When the flowing liquid asphalt accumulates excessively at one end of the storage tank 1, the excess asphalt will flow along the guide cavity layer between the inner liner 5 and the storage tank 1 towards the end of the storage tank 1 closer to the front tube 211. That is, while the heat-conducting plate II 44 drives the guide vanes I 472 and II 473 to rotate, disturbing the liquid asphalt inside the storage tank 1 and promoting the mixing of asphalt between the stationary height layers, the liquid asphalt inside the storage tank 1 will also be affected. The liquid asphalt inside the storage tank 1 will also form a circulating flow process inside the inner liner shell 5 and along the guide cavity layer between the inner liner shell 5 and the storage tank 1. The liquid asphalt inside the storage tank 1 mixes and flows in two dimensions, which improves the uneven heat conduction of the front coil 25 and the rear coil 26, and further enhances the uniformity of the liquid asphalt inside the storage tank 1.
