The embodiments of this utility model will now be described based on its overall structure.

[0030] See Figure 1 A rubber asphalt processing device includes a desulfurizing agent storage tank 1, which is connected to a rubber powder modification tank 3 via a pipe 2. A metering pump 19 is connected to the pipe 2. The rubber powder modification tank 3 is provided with an air inlet and an air outlet. The outlet of the rubber powder modification tank 3 is connected to a buffer tank 4.

[0031] A diversion pipe 5 is connected to the bottom of the buffer tank 4. The diversion pipe 5 is connected to the metering tank 6. The metering tank 6 is connected to the reaction tank 7. An air inlet pipe 8 is connected to the buffer tank 7.

[0032] The reaction tank 7 is connected to an air outlet pipe 9. The inlet of the reaction tank 7 is connected to an asphalt modification tank 23. A valve 10 is connected between the asphalt modification tank 23 and the reaction tank 7. The outlet of the reaction tank 7 is connected to a storage tank 11. The storage tank 11 is provided with an air inlet and an air outlet.

[0033] The rubber powder modification tank 3 and the reaction tank 7 are connected to a horizontal agitator 12 and a heating element 14, and the asphalt modification tank 23 is connected to a vertical agitator 13 and a heating element 14.

[0034] The rubber powder modification tank 3 is used to desulfurize and modify the rubber granules obtained after crushing waste tires. After long-term use, the rubber in waste tires gradually ages and its performance declines. Desulfurization can break the cross-linking bonds in the rubber, transforming it into recycled rubber with certain plasticity and flowability, thereby restoring some of the rubber's properties and allowing it to be used again as a raw material for rubber asphalt production.

[0035] In the desulfurization modification process of rubber granules, nitrogen (displacement gas) is first introduced into the air inlet of the rubber powder modification tank 3 to expel the air from the tank, thereby replacing the oxygen. Then, the rubber granules are fed into the tank 3 from the feed inlet, and the heating element 14 heats the granules, causing the rubber molecular chains to break and achieving desulfurization. Simultaneously, the desulfurizing agent from the desulfurizing agent storage tank 1 is added to the rubber powder modification tank 3 via the metering pump 19.

[0036] The metering pump 19 can control the content of desulfurizer added to the rubber powder modification tank 3, achieving automated control. The horizontal agitator 12 in the rubber powder modification tank 3 can fully mix the rubber granules with the desulfurizer, and at the same time, desulfurize the rubber granules under certain temperature and mechanical shear force, thereby enhancing the desulfurization effect.

[0037] During the desulfurization modification process of rubber granules, desulfurized waste gas will be generated in the rubber powder modification tank 3, and the waste gas will be discharged through the outlet of the rubber powder modification tank 3.

[0038] After desulfurization and modification, the rubber granules enter the buffer tank 4. Nitrogen gas is introduced into the buffer tank 4 through the air inlet pipe in advance to replace the air in the buffer tank 4. An insulation layer is installed on the inner wall of the buffer tank 4, and an insulation layer is also installed on the outer wall of the buffer tank 4.

[0039] The rubber granules in the buffer tank 4 enter the metering tank 6 through the diversion pipe 5. In this embodiment, a total of two metering tanks 6 and two diversion pipes 5 are provided. One metering tank 6 is used to meter the rubber granules entering the reaction tank 7, and the other metering tank 6 is used to adjust the amount of rubber granules at any time during metering.

[0040] Referring to the rubber powder modifying tank 3, the asphalt modifying tank 23 is equipped with a modifier storage tank, which is connected to the asphalt modifying tank via a pipeline connected to a metering pump. The asphalt modifying tank 23 is used to modify the base asphalt. The vertical mixer 13 and heating element 14 in the asphalt modifying tank 23 heat the asphalt, reducing its viscosity and improving its fluidity. This allows for more uniform coating of rubber particles during mixing, promoting thorough mixing and interaction between the two, which is beneficial for forming a stable rubber-asphalt system. Simultaneously, adding modifier to the asphalt modifying tank 23 through the modifier storage tank enhances the compatibility between asphalt and rubber, thereby improving the performance stability of the rubber-asphalt.

[0041] The asphalt modification tank 23 is equipped with an air outlet and an air inlet. Before the asphalt enters the asphalt modification tank 23, nitrogen gas is introduced into the asphalt modification tank 23 to replace the air in the asphalt modification tank 23. Nitrogen gas does not affect the modification of the asphalt and can also replace the oxygen in the asphalt modification tank 23. Because asphalt is prone to oxidation reaction with oxygen in the air at high temperatures, leading to the deterioration of asphalt performance, using nitrogen gas to remove the air in the asphalt modification tank 23 in advance can create an oxygen-free asphalt modification tank 23, reduce the degree of oxidation of the asphalt during the modification process, and help maintain the original properties and modification effect of the asphalt. The reaction tank 7 is purged with nitrogen gas in advance to replace the air in it. The modified rubber granules and asphalt enter the reaction tank 7, and then the rubber granules and asphalt are heated and mixed by the horizontal agitator 12 and the heating element 14. The gas generated during the reaction in the reaction tank 7 is discharged through the air outlet on the reaction tank 7.

[0042] The equipment is equipped with a nitrogen venting system for the nitrogen intake of the rubber powder modification tank 3, buffer tank 4, metering tank 6, asphalt modification tank 23, and reaction tank 74. The gases discharged from these tanks are uniformly discharged into the exhaust gas treatment system through a shared exhaust pipe, ensuring that the production waste gas meets the company's environmental protection requirements. A nitrogen control valve can be installed on the nitrogen pipeline in the nitrogen venting system.

[0043] The aforementioned rubber asphalt processing equipment modifies rubber granules and asphalt separately, and then heats and mixes the modified rubber granules and asphalt to prepare rubber asphalt. To prepare rubber asphalt for different applications, different modifiers are typically added to the reaction vessel.

[0044] Therefore, referring to the rubber powder modification tank 3, the reaction tank 7 is connected to a modifier pipeline 21, the modifier pipeline 21 is connected to the modifier storage tank 20, and the modifier pipeline 21 is connected to a metering pump 19.

[0045] In one specific implementation, three modifier storage tanks are used, each equipped with three pipelines and three metering pumps. One tank stores styrene-butadiene-styrene block copolymer (SBS), producing rubber asphalt for high-grade highway pavements. Another tank stores styrene-butadiene rubber (SBR), producing rubber asphalt for road construction in low-temperature regions. A third tank stores sulfur crosslinking agent, producing rubber asphalt for airport runways. The above embodiments are merely illustrative of the use of the reaction tanks. In other implementations of industrial-scale rubber asphalt production, modifier storage tanks and modifiers can be added as required. For example, SBS and SBR can be added simultaneously to reaction tank 7, with the amount controlled by metering pumps.

[0046] The storage tank 11 is used to store the produced rubber asphalt. Before the rubber asphalt enters the storage tank 11, nitrogen gas is introduced into the storage tank 11 through the air inlet to replace the air (oxygen) in the storage tank 11. After the rubber asphalt is stored in the storage tank 11, a nitrogen gas covering layer is formed above the surface of the rubber asphalt to isolate it from the air. At the same time, the nitrogen gas inlet at the top of the storage tank is maintained at a slight positive pressure (0.02~0.05MPa). A breather valve is installed at the air outlet of the storage tank 11. When the temperature fluctuation of the storage tank causes the gas to expand / contract, the breather valve preferentially discharges nitrogen gas rather than draws in air.

[0047] The rubber asphalt processing equipment provided in the above embodiments introduces nitrogen gas into each tank before it enters the processing equipment, replacing the oxygen in the tanks and preventing oxygen from affecting the modification of rubber and asphalt. Simultaneously, the presence of nitrogen gas stabilizes the reaction environment, reducing interference from impurities such as moisture and carbon dioxide in the air on the modification process, thus helping to ensure the consistency and stability of the modification reaction. Furthermore, the processing equipment is suitable for the industrial production of rubber asphalt, meeting the equipment requirements for industrial-scale rubber asphalt production.

[0048] Rubber-asphalt processing equipment allows for the separate modification of rubber and asphalt during industrial production. Separate modification enables the targeted selection of modifiers and methods based on the individual characteristics of rubber and asphalt, precisely optimizing their properties. This allows them to exert a better synergistic effect after mixing. The modified rubber particles can better encapsulate and cross-link with the modified asphalt, achieving a better balance in the elasticity, viscosity, and cohesion of the rubber-asphalt.

[0049] Asphalt is typically modified at high temperatures, while rubber can degrade or undergo other adverse reactions at excessively high temperatures. Modifying them separately can prevent damage to the rubber during the high-temperature modification process of asphalt. Furthermore, when mixing them, it is only necessary to control the temperature within a suitable range to ensure that the two materials are fully integrated.

[0050] See Figure 3 The rubber powder modification tank 3 is provided with partitions 15 on both sides, which divide the interior of the rubber powder modification tank 3 into a heating and stirring zone 31 and a component installation zone 32. The horizontal stirring blades of the horizontal stirrer 12 are located in the heating and stirring zone 31, and the heating component 14 is located in the heating and stirring zone 31.

[0051] See Figure 5The heating component 14 is a heat transfer oil heating tube, which includes a spirally arranged spiral tube 141. The first end of the spiral tube 141 is connected to a first straight tube 142, and the end of the spiral tube 141 is connected to a second straight tube 143. The second straight tube 142 extends from the end of the spiral tube 141 to the first end of the spiral tube 141 and is flush with the end face of the second straight tube 143, so that the oil inlet and oil outlet of the heat transfer oil heating tube are located on the same side.

[0052] See Figure 1 and Figure 3 The heat transfer oil heating pipe is installed in the heating and stirring zone 31 of the rubber powder modification tank 3, and the spiral tube 141 is connected to the inner wall of the rubber powder modification tank 3. The first straight tube 142 and the second straight tube 143 pass through the partition 15 and are located in the component installation zone 32. The horizontal stirring blades of the horizontal stirrer 12 are located in the middle of the tank. In the heating and stirring zone 31, a spiral zone 1410 is formed in the middle of the spiral tube 141. The stirring shaft and the horizontal stirring blades of the horizontal stirrer 12 pass through the spiral zone 1410 formed by the spiral tube 141. Therefore, the horizontal stirring blades will not affect the heat transfer oil heating pipe when they rotate and stir.

[0053] The installation method of asphalt modification tank 23 is different from that of rubber powder modification tank 3. Rubber powder modification tank 3 is installed horizontally, such as... Figure 1 As shown, the asphalt modification tank 23 is installed vertically. The first straight pipe 142 and the second straight pipe 143 of the heat transfer oil heating pipe in the asphalt modification tank 23 extend out from the top of the asphalt modification tank 23. The stirring shaft and vertical stirring blades of the vertical agitator 13 pass through the middle of the spiral tube 141 and are located in the spiral zone 1410 formed by the spiral tube 141. Therefore, the rotation of the vertical stirring blades will not affect the heat transfer oil heating pipe.

[0054] See Figure 2 The bottom of the buffer tank 4 is connected to a discharge pipe 16, and a control valve 17 is connected to the discharge pipe 16. The air inlet pipe 8 is connected to the discharge pipe 16, and an air outlet is provided at the top of the buffer tank 4. The air inlet pipe 8 is located between the bottom of the buffer tank 4 and the metering tank 6. When nitrogen is introduced into the air inlet pipe 8, the control valve 17 and the valve on the metering tank 6 are opened. After passing through the discharge pipe 16, the nitrogen enters upward into the buffer tank 4, displacing the air in the buffer tank 4, and then enters downward into the diversion pipe 5, the metering tank 6, and the reaction tank 7, displacing the air in the diversion pipe 5, the metering tank 6, and the reaction tank 7.

[0055] Meanwhile, the discharge pipe 16 is vertically installed on the bottom of the buffer tank 4, while the air inlet pipe 8 is inclinedly installed on the discharge pipe 16. A blocking valve is installed at the position of the air inlet pipe 8. The blocking valve opens when replacing air and closes when the buffer tank 4 discharges material, so as to prevent rubber granules from flowing back into the air inlet pipe 8 and clogging the air inlet pipe 8.

[0056] See Figure 4 The reaction tank 7 is equipped with partition plates 18 on both sides, which divide the interior of the reaction tank 7 into a reaction zone 71 and a component placement zone 72. The installation method of the horizontal agitator 12 and the heat transfer oil heating pipe of the heating component 14 in the reaction tank 7 is the same as that in the rubber powder modification tank 3. In addition, temperature sensors are installed on the rubber powder modification tank 3, the asphalt modification tank 23, and the reaction tank 7 to detect the temperature of the materials within. For the reaction tank 7 and the rubber powder modification tank 3, the temperature sensors are installed on the partition plates 18 and 15, respectively, while those in the asphalt modification tank 23 are directly installed on the top of the asphalt modification tank 23.

[0057] See Figure 4 When the air in the distributor pipe 5, metering tank 6, and reaction tank 7 is replaced, nitrogen enters from the inlet pipe 8 and flows downwards into the distributor pipe 5, metering tank 6, and reaction tank 7, finally exiting from the outlet pipe 9 at the top of the reaction tank 7. The outlet pipe 9 is located in the component placement area 72 of the reaction tank 7. One end of the outlet pipe 9 is connected to the partition plate 18, thereby communicating with the reaction zone 71 of the reaction tank 7, and the other end of the outlet pipe 9 passes through the tank body of the reaction tank 7.

[0058] In summary, the rubber asphalt processing equipment provided by this utility model introduces nitrogen gas into each tank before production to replace oxygen, stabilize the reaction environment, avoid interference from airborne impurities, and ensure consistent and stable modification reactions. This equipment is suitable for industrial production of rubber asphalt, supports separate modification of rubber and asphalt, and allows for precise optimization of performance based on their respective characteristics, promoting synergistic effects after mixing. Simultaneously, separate modification avoids the damage to rubber caused by high-temperature asphalt modification, facilitates temperature control during mixing, and ensures thorough fusion.
