Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a device and working method for preventing segregation in high-content rubber powder modified asphalt storage. Background Technology

[0002] The maximum rubber powder content in permanent pavement rubber powder asphalt mixtures reaches 50%. High-content rubber powder asphalt is difficult to store using traditional methods, and asphalt segregation is very likely to occur, making it difficult to control the quality.

[0003] Currently, most asphalt storage tanks used in domestic asphalt pavement projects are vertical or horizontal mixing tanks. However, when used for storing and using high-content rubber-modified asphalt, neither type of mixing achieves ideal results due to differences in rotational speed and blade radius. This often leads to the sedimentation of floating matter and large amounts of particulate matter within the tank, resulting in slow asphalt heating and segregation, thus affecting normal production. Therefore, a device and operating method for preventing segregation in the storage of high-content rubber-modified asphalt are needed. Summary of the Invention

[0025] Preferably, the modified asphalt anti-segregation mechanism includes a rotating sealing disc, with two rotating sealing discs symmetrically distributed around the axis of the outer storage tank, and the surface of the rotating sealing disc is adapted to slide and fit the inner wall of the wear-resistant contact layer inside the outer storage tank.

The inner walls of the plurality of anti-segregation storage cavities are rotatably connected to a stirring shaft through bearings.

[0027] One end of the stirring shaft extends to the surface of one of the rotating sealing discs, and a driven gear is fixedly sleeved on one end of the stirring shaft.

[0028] A drive gear is fixedly sleeved on the surface of the rotary drive shaft. The surface of the drive gear meshes with the surface of the driven gear. The gear ratio between the drive gear and the driven gear is 1:10.

[0029] Preferably, a fixed limiting ring is slidably connected to the surface of the rotating sealing disc, and the two fixed limiting rings are respectively fixedly connected to both ends of the outer storage tank.

[0030] One of the fixed limiting rings has a fixed mounting plate fixedly connected to its surface, and an anti-segregation drive reducer is fixedly mounted on the surface of the fixed mounting plate. One end of the rotary drive shaft is fixedly connected to the power output end of the anti-segregation drive reducer.

[0031] An anti-segregation drive motor is fixedly mounted on the surface of the anti-segregation drive reducer and electrically connected to the controller via a cable. The output shaft of the anti-segregation drive motor is fixedly connected to the power input end of the anti-segregation drive reducer.

[0032] Preferably, a method for operating a storage anti-segregation device for high-content rubber powder modified asphalt includes the following steps:

[0033] Step 1: Before storing high-content rubber powder modified asphalt to prevent segregation, first program and set the controller to facilitate automatic control of the feeding and discharging turning mechanism, quantitative storage control mechanism and modified asphalt anti-segregation mechanism.

[0034] Step 2: After the controller control program is set, when storing high-content rubber powder modified asphalt to prevent segregation, the controller automatically controls the feeding and discharging turning mechanism to work. After the feeding and discharging turning mechanism flips the quantitative storage control mechanism upward, asphalt storage material is fed into the modified asphalt anti-segregation mechanism.

[0035] Specifically, when feeding modified asphalt storage material, the controller controls the tilting drive motor to work. The tilting drive motor drives the tilting drive worm to rotate through the tilting drive reducer. The tilting drive worm drives the drive worm wheel ring to rotate. The drive worm wheel ring drives the outer storage bucket to rotate through the connecting support column, which drives the sealing cover and the inlet and outlet boxes to move upward, so that the inlet and outlet hoppers are perpendicular to the ground.

[0036] Step 3: After the feed and discharge tilting mechanism drives the quantitative storage control mechanism to tilt upwards, the modified asphalt enters the feed and discharge hopper. Then, the controller automatically controls the electric rotary discharge valve and the feed and discharge drive motor to work. The electric rotary discharge valve discharges the modified asphalt in the feed and discharge hopper into the feed and discharge box in a quantitative rotary manner. At the same time, the feed and discharge drive motor drives the feed and discharge drive shaft to rotate through the feed and discharge drive reducer. The feed and discharge drive shaft drives the drive spiral blade to rotate, which rotates and squeezes the modified asphalt in the feed and discharge box into the anti-segregation storage chamber.

[0037] Step 4: After the modified asphalt enters an anti-segregation storage chamber and reaches three-fifths of its volume, the controller activates the anti-segregation drive motor. The anti-segregation drive motor drives the rotary drive shaft via the anti-segregation drive reducer, which in turn rotates the anti-segregation storage chamber. After the anti-segregation storage chamber containing modified asphalt moves away from the inlet / outlet chute, the inner wall of the next empty anti-segregation storage chamber connects with the inner wall of the inlet / outlet chute. At this point, the controller stops the anti-segregation drive motor. Then, modified asphalt is added to the empty anti-segregation storage chamber, and the controller automatically controls the rotation of the anti-segregation storage chamber. This process is repeated sequentially to quantitatively feed and store material into multiple anti-segregation storage chambers.

[0038] Step 5: After the quantitative storage of material in the anti-segregation storage chamber is completed, the controller automatically controls the anti-segregation drive motor to work. The anti-segregation drive motor drives the rotary drive shaft to rotate through the anti-segregation reducer, which in turn drives multiple anti-segregation storage chambers to rotate. As the multiple anti-segregation storage chambers rotate, the modified asphalt inside them moves and mixes, preventing segregation. At the same time, when the anti-segregation storage chambers rotate and mix, they drive the drive gear to rotate. The drive gear drives multiple driven gears to rotate rapidly. The driven gears drive the stirring shafts inside the multiple anti-segregation storage chambers to rotate. The rotation of the stirring shafts drives the stirring shovels to rotate rapidly, stirring and mixing the modified asphalt inside the anti-segregation storage chambers to prevent segregation.

[0039] Step Six: When discharging modified asphalt after storage, the controller controls the infeed / outfeed turning mechanism to move in the opposite direction, driving the quantitative storage control mechanism downwards. This causes the opening of the infeed / outfeed hopper in the quantitative storage control mechanism to face downwards. At this time, the modified asphalt inside the anti-segregation storage chamber enters the sealed cover through the infeed / outfeed chute. Then, the controller controls the infeed / outfeed drive motor to reverse, which drives the infeed / outfeed drive shaft to reverse through the infeed / outfeed drive reducer. This reverses the drive auger, causing the modified asphalt to rotate and be squeezed into the infeed / outfeed box and fall into the electric rotary discharge valve. Then, the electric rotary discharge valve is controlled to operate, quantitatively discharging the modified asphalt through the infeed / outfeed hopper. After the modified asphalt in one anti-segregation storage chamber is discharged, the controller controls the anti-segregation drive motor to operate, driving the anti-segregation storage chamber to rotate, and quantitatively discharging the modified asphalt in other anti-segregation storage chambers in sequence.

[0040] The beneficial effects of this invention are as follows:

[0041] 1. By setting up a feeding and discharging tilting mechanism, a quantitative storage control mechanism, and a modified asphalt anti-segregation mechanism, when storing high-content rubber powder modified asphalt, the feeding and discharging tilting mechanism drives the quantitative storage control mechanism to rotate, facilitating feeding and storage of the modified asphalt and subsequent discharge for use. During feeding and storage, the quantitative storage control mechanism controls the quantitative feeding and discharging. Then, through multiple anti-segregation storage chambers within the modified asphalt anti-segregation mechanism, the modified asphalt is stored in separate compartments, preventing the accumulation and compression of large amounts of modified asphalt, which leads to the sedimentation of floating matter and particles. During storage, the rotation of the anti-segregation storage chambers keeps the modified asphalt inside in motion and mixed, and the stirring shaft and stirring shovel further agitate and mix the modified asphalt. This solves the problem of existing asphalt storage tanks used for storing and using high-content rubber powder modified asphalt, which often result in floating matter and large amounts of particle sedimentation, causing slow asphalt heating, segregation, and affecting normal production.

[0042] 2. By setting up a feeding and discharging overturning mechanism and a quantitative storage control mechanism, the modified asphalt is quantitatively fed, stored, and discharged during use, thereby achieving a better effect of preventing segregation of the modified asphalt.

[0043] 3. By setting up a modified asphalt anti-segregation mechanism, multiple anti-segregation storage chambers are set up during use. This not only keeps the modified asphalt moving, mixing and stirring during storage to prevent segregation, but also prevents a large amount of modified asphalt from piling up together, resulting in floating matter and particle sedimentation, and prevents a large amount of modified asphalt from piling up and becoming impossible to mix.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] Example 1

[0056] Reference Figure 1-9 A device for preventing segregation in storage of high-content rubber powder modified asphalt includes a support base 1 with an arc-shaped upper surface and a controller 2 fixedly installed on the surface of the support base 1. The surface of the support base 1 is provided with multiple evenly distributed limiting grooves 3. The inner wall of the limiting grooves 3 is arc-shaped, and one of the limiting grooves 3 has a drive groove 4 on its inner wall.

[0057] The surface of the support base 1 is provided with a feeding and discharging tilting mechanism. Inside the feeding and discharging tilting mechanism is a quantitative storage control mechanism for preventing segregation of high-content rubber powder modified asphalt. Inside the quantitative storage control mechanism is a modified asphalt anti-segregation mechanism for preventing segregation of high-content rubber powder modified asphalt.

[0058] The feeding and discharging tilting mechanism is used to drive the quantitative storage control mechanism to tilt, so that the quantitative storage control mechanism can perform quantitative storage feeding and quantitative storage discharging.

[0059] The feeding and discharging tilting mechanism includes a rotating support ring 5 and a driving worm gear ring 501. The surfaces of the multiple rotating support rings 5 ​​are slidably connected to the inner walls of multiple limiting grooves 3.

[0060] Support rollers 502 are slidably connected to the surface of the rotating support ring 5. Multiple support rollers 502 are symmetrically distributed around the axes of multiple rotating support rings 5. The two ends of the support rollers 502 are rotatably connected to the inner wall of the limiting slide groove 3 through bearings.

[0061] Furthermore, the limiting groove 3 has the characteristics of limiting and positioning the rotating support ring 5 and providing rotational support, and the support roller 502 has the effect of reducing the contact area with the surface of the rotating support ring 5, so that the rotating support ring 5 can slide in the limiting groove 3.

[0062] The surface of the drive worm gear ring 501 is slidably connected to the inner wall of one of the limiting grooves 3 and the drive groove 4.

[0063] A tilting drive reducer 503 is fixedly mounted on the surface of the support base 1. A tilting drive motor 504 is fixedly mounted on the surface of the tilting drive reducer 503 and electrically connected to the controller 2 via a cable. The output shaft of the tilting drive motor 504 is fixedly connected to the power input end of the tilting drive reducer 503.

[0064] The inner wall of the drive groove 4 is provided with a mounting groove 505 corresponding to the tilt drive reducer 503. The inner wall of the mounting groove 505 is rotatably connected to the tilt drive worm gear 506 through a bearing.

[0065] One end of the tilting drive worm 506 is fixedly connected to the power output end of the tilting drive reducer 503, and the surface of the tilting drive worm 506 meshes with the surface of the drive worm ring 501.

[0066] During use, the controller 2 automatically controls the operation of the tilt drive motor 504. The output shaft of the tilt drive motor 504 drives the tilt drive reducer 503 to work. The tilt drive reducer 503 drives the tilt drive worm 506 to rotate. The tilt drive worm 506 drives the drive worm wheel ring 501 to rotate.

[0067] Multiple connecting support columns 507 arranged in a ring array are fixedly connected to the inner walls of the rotating support ring 5 and the driving worm gear ring 501. The surface of the connecting support column 507 is T-shaped, and a storage outer barrel 508 is fixedly connected to one end of the connecting support column 507.

[0068] The quantitative storage control mechanism is used to prevent segregation of high-content rubber powder modified asphalt during storage, and to quantitatively control the feeding and discharging of the material.

[0069] The quantitative storage control mechanism includes a sealing cover 6 with an arc-shaped surface, the surface of which is fixedly connected to the surface of the outer storage tank 508.

[0070] The inner wall of the outer storage tank 508 is provided with an inlet / outlet groove 601, and the inner wall of the inlet / outlet groove 601 is fixedly connected to the inner wall of the sealing cover 6.

[0071] The inner wall of the outer storage tank 508 and the inner wall of the sealing cover 6 are both fixedly connected with a heat insulation layer 602, and the inner wall of the heat insulation layer 602 is fixedly connected with a wear-resistant contact layer 603.

[0072] The interior of the thermal insulation layer 602 is made of aerogel felt, and the wear-resistant contact layer 603 is made of chromium steel.

[0073] Furthermore, aerogel felt possesses properties such as softness, ease of cutting, low density, inorganic fire resistance, overall hydrophobicity, and environmental friendliness. It has the following characteristics:

[0074] 1. Excellent heat insulation effect

[0075] Aerogel felt has a thermal insulation effect 2-5 times that of traditional thermal insulation materials, and according to the Arrhenius experiment, the theoretical service life of high-temperature pipelines is close to 20 years.

[0076] 2. Reduce the thickness of the insulation layer

[0077] Aerogel felt achieves the same thermal insulation effect, but is only a fraction of the thickness of traditional materials. It exhibits low heat loss and high space utilization after insulation. Furthermore, these performance advantages are even more pronounced at high temperatures.

[0078] 3. Water repellency and fire resistance

[0079] Aerogel felt is relatively hydrophobic, effectively preventing moisture from entering pipes and equipment. It also boasts fire resistance ratings from B1 to A, and its unique three-dimensional network structure avoids the significant decrease in insulation performance caused by sintering, deformation, and settling that occur with other insulation materials during long-term high-temperature use.

[0080] 4. Convenient construction

[0081] Aerogel felt is lightweight, easy to cut and sew to fit various shapes of pipes and equipment for insulation, and requires less time and manpower for installation.

[0082] 5. Save on transportation costs

[0083] Smaller package size and lighter weight can significantly reduce the transportation costs of insulation materials.

[0084] Furthermore, chromium steel refers to alloy steel containing chromium. Chromium increases the hardenability of steel, improving its strength and wear resistance. It also has high oxidation resistance and corrosion resistance.

[0085] One end of the sealing cover 6 is fixedly connected to the inlet / outlet box 604. An electric rotary unloading valve 605 is fixedly installed on the upper surface of the inlet / outlet box 604. The electric rotary unloading valve 605 is electrically connected to the controller 2 via a cable. The surface of the electric rotary unloading valve 605 is fixedly connected to the inlet / outlet hopper 606.

[0086] In use, the number of rotations of the electric rotary discharge valve 605 can be controlled by the controller 2 to control the feed and discharge of the stored modified asphalt. At the same time, the electric rotary discharge valve 605 also has the feature of sealing the feed and discharge boxes 604.

[0087] An infeed / outfeed drive reducer 607 is fixedly mounted on the surface of the infeed / outfeed box 604. An infeed / outfeed drive motor 608 is fixedly mounted on the surface of the infeed / outfeed drive reducer 607 and electrically connected to the controller 2 via a cable. The output shaft of the infeed / outfeed drive motor 608 is fixedly connected to the power input end of the infeed / outfeed drive reducer 607.

[0088] The power output end of the feed and discharge drive reducer 607 is fixedly connected to the feed and discharge drive shaft 609. One end of the feed and discharge drive shaft 609 extends to the inner wall of the sealing cover 6, and the other end of the feed and discharge drive shaft 609 is rotatably connected to the inner wall of the sealing cover 6 through a bearing.

[0089] A drive spiral blade 610 is fixedly connected to the surface of the feed / discharge drive shaft 609. The surface of the drive spiral blade 610 is slidably connected to the inner wall of the sealing cover 6 and extends to the inner wall of the feed / discharge box 604.

[0090] In use, the controller 2 controls the operation of the feed and discharge drive motor 608. The feed and discharge drive motor 608 drives the feed and discharge drive shaft 609 to rotate through the feed and discharge drive reducer 607, which in turn drives the drive screw blade 610 to rotate. This drives the asphalt in the feed and discharge box 604 into the sealing cover 6, and then into the storage outer barrel 508. Alternatively, the asphalt inside the storage outer barrel 508 can be driven from the sealing cover 6 into the feed and discharge box 604. Then, the asphalt is discharged through the electric rotary discharge valve 605 and the feed and discharge hopper 606.

[0091] By setting up a feeding and discharging overturning mechanism and a quantitative storage control mechanism, the modified asphalt can be quantitatively fed, stored, and discharged during use, thereby achieving a better effect of preventing segregation in the storage of modified asphalt.

[0092] Among them, the modified asphalt anti-segregation mechanism is used for the anti-segregation storage of high-content rubber powder modified asphalt.

[0093] The modified asphalt anti-segregation mechanism includes a rotating sealing disc 7. The two rotating sealing discs 7 are symmetrically distributed around the axis of the outer storage tank 508. The surface of the rotating sealing disc 7 is adapted to slide and connect with the inner wall of the wear-resistant contact layer 603 inside the outer storage tank 508.

[0094] A rotary drive shaft 701 is fixedly connected to the surface of the rotary sealing disk 7. Multiple partition plates 702 arranged in a ring array are fixedly connected to the surface of the rotary drive shaft 701. The surface of the partition plates 702 is fixedly connected to the surface of the rotary sealing disk 7. The surface of the partition plates 702 is slidably connected to the surface of the wear-resistant contact layer 603 inside the storage outer barrel 508. Anti-segregation storage cavities 703 are provided on the surfaces of two adjacent partition plates 702 and the surface of the rotary sealing disk 7. The inner walls of multiple anti-segregation storage cavities 703 are rotatably connected to a stirring shaft 704 through bearings. Multiple stirring shovels 705 arranged in a spiral curve array are fixedly connected to the surface of the stirring shaft 704.

[0095] One end of the stirring shaft 704 extends to the surface of one of the rotating sealing disks 7, and a driven gear 706 is fixedly sleeved on one end of the stirring shaft 704.

[0096] A drive gear 707 is fixedly sleeved on the surface of the rotary drive shaft 701. The surface of the drive gear 707 meshes with the surface of the driven gear 706. The tooth ratio of the drive gear 707 to the driven gear 706 is 1:10.

[0097] In use, the drive gear 707 meshes with the driven gear 706, so that the drive gear 707 rotates and drives the driven gear 706 to rotate. At the same time, since the gear ratio of the drive gear 707 to the driven gear 706 is 1:10, the driven gear 706 rotates ten times for every one revolution of the drive gear 707. While the rotary drive shaft 701 drives the anti-segregation storage chamber 703 to rotate, it also drives the stirring shaft 704 and the stirring shovel 705 to rotate. The rotation of the stirring shovel 705 stirs the high-content rubber powder modified asphalt storage material inside the anti-segregation storage chamber 703 to prevent segregation.

[0098] Furthermore, in order to achieve a better anti-segregation storage effect, the volume of high-content rubber powder modified asphalt stored inside each anti-segregation storage cavity 703 shall not exceed three-fifths of the volume of the anti-segregation storage cavity 703.

[0099] The surface of the rotary sealing disc 7 is slidably connected with fixed limiting rings 708, and the two fixed limiting rings 708 are fixedly connected to the two ends of the storage outer barrel 508 respectively.

[0100] During use, the rotating sealing disc 7 is limited by two fixed limiting rings 708, thereby limiting and positioning the anti-segregation storage chamber 703 inside the storage outer barrel 508.

[0101] One of the fixed limiting rings 708 has a fixed mounting plate 709 fixedly connected to its surface. An anti-segregation drive reducer 710 is fixedly mounted on the surface of the fixed mounting plate 709. One end of the rotary drive shaft 701 is fixedly connected to the power output end of the anti-segregation drive reducer 710.

[0102] An anti-segregation drive motor 711 is fixedly mounted on the surface of the anti-segregation drive reducer 710 and electrically connected to the controller 2 via a cable. The output shaft of the anti-segregation drive motor 711 is fixedly connected to the power input end of the anti-segregation drive reducer 710.

[0103] By setting up a modified asphalt anti-segregation mechanism, multiple anti-segregation storage chambers are set up during use. This not only keeps the modified asphalt moving, mixing, and stirring during storage to prevent segregation, but also prevents a large amount of modified asphalt from piling up together, resulting in floating matter and particle sedimentation, as well as preventing a large amount of modified asphalt from piling up and becoming impossible to mix.

[0104] By setting up a feeding and discharging tilting mechanism, a quantitative storage control mechanism, and a modified asphalt anti-segregation mechanism, when storing high-content rubber powder modified asphalt, the feeding and discharging tilting mechanism drives the quantitative storage control mechanism to rotate, facilitating feeding and storage of the modified asphalt and its subsequent discharge. During feeding and storage, the quantitative storage control mechanism controls the feeding and discharging quantities. Multiple anti-segregation storage chambers 703 within the modified asphalt anti-segregation mechanism separate the modified asphalt for separate storage, preventing the accumulation and compression of large quantities of modified asphalt, which leads to the sedimentation of floating matter and particles. During storage, the rotation of the anti-segregation storage chambers 703 keeps the modified asphalt inside in motion and mixed, and the stirring shaft 704 and stirring shovel 705 further agitate and mix the modified asphalt. This solves the problem of existing asphalt storage tanks used for storing and using high-content rubber powder modified asphalt, which often result in floating matter and large amounts of particle sedimentation, causing slow asphalt heating and segregation, thus affecting normal production.

[0105] Example 2

[0106] Reference Figure 1-9 A method for operating a storage device for preventing segregation of high-content rubber powder modified asphalt includes the following steps:

[0107] Step 1: Before storing high-content rubber powder modified asphalt to prevent segregation, first program and set the controller 2 so that the controller 2 can automatically control the feeding and discharging turning mechanism, the quantitative storage control mechanism and the modified asphalt anti-segregation mechanism.

[0108] Step 2: After the control program of controller 2 is set, when storing high-content rubber powder modified asphalt to prevent segregation, controller 2 automatically controls the feeding and discharging turning mechanism to work. After the feeding and discharging turning mechanism flips the quantitative storage control mechanism upward, asphalt storage material is fed into the modified asphalt anti-segregation mechanism.

[0109] Specifically, when feeding modified asphalt storage material, controller 2 controls the tilting drive motor 504 to work. The tilting drive motor 504 drives the tilting drive worm 506 to rotate through the tilting drive reducer 503. The tilting drive worm 506 drives the drive worm wheel ring 501 to rotate. The drive worm wheel ring 501 drives the storage outer barrel 508 to rotate through the connecting support column 507, which drives the sealing cover 6 and the inlet / outlet box 604 to move upward, so that the inlet / outlet hopper 606 is perpendicular to the ground and upward.

[0110] Step 3: After the feed-out turning mechanism drives the quantitative storage control mechanism to flip upward, the modified asphalt enters the feed-out hopper 606. Then, the controller 2 automatically controls the electric rotary unloading valve 605 and the feed-out drive motor 608 to work. The electric rotary unloading valve 605 quantitatively and rotaryly unloads the modified asphalt in the feed-out hopper 606 into the feed-out box 604. At the same time, the feed-out drive motor 608 drives the feed-out drive shaft 609 to rotate through the feed-out drive reducer 607. The feed-out drive shaft 609 drives the drive spiral blade 610 to rotate, rotating and extruding the modified asphalt in the feed-out box 604 into the anti-segregation storage chamber 703.

[0111] Step 4: After the modified asphalt enters an anti-segregation storage chamber 703 and reaches three-fifths of its volume, the controller 2 controls the anti-segregation drive motor 711 to operate. The anti-segregation drive motor 711 drives the rotary drive shaft 701 to rotate through the anti-segregation drive reducer 710. The rotary drive shaft 701 drives the anti-segregation storage chamber 703 to rotate. After the anti-segregation storage chamber 703 containing modified asphalt moves away from the inlet / outlet trough 601, the inner wall of the next empty anti-segregation storage chamber 703 connects with the inner wall of the inlet / outlet trough 601. Then, the controller 2 controls the anti-segregation drive motor 711 to stop. Modified asphalt is then fed into the empty anti-segregation storage chamber 703, and the controller 2 automatically controls the rotation of the anti-segregation storage chamber 703. Quantitative feeding and storage are carried out in multiple anti-segregation storage chambers 703 in sequence.

[0112] Step 5: After the quantitative storage of material in the anti-segregation storage chamber 703 is completed, the controller 2 automatically controls the anti-segregation drive motor 711 to work. The anti-segregation drive motor 711 drives the rotary drive shaft 701 to rotate through the anti-segregation reducer, which in turn drives multiple anti-segregation storage chambers 703 to rotate. As the multiple anti-segregation storage chambers 703 rotate, the modified asphalt inside them moves and mixes to prevent segregation. At the same time, when the anti-segregation storage chambers 703 rotate and mix, they drive the drive gear 707 to rotate. The drive gear 707 simultaneously drives multiple driven gears 706 to rotate rapidly. The driven gears 706 drive the stirring shafts 704 inside the multiple anti-segregation storage chambers 703 to rotate. The rotation of the stirring shafts 704 drives the stirring spatula 705 to rotate rapidly, stirring and mixing the modified asphalt inside the anti-segregation storage chambers 703 to prevent segregation.

[0113] Step Six: When discharging modified asphalt after storage, the controller 2 controls the infeed / outfeed tilting mechanism to move in the reverse direction, driving the quantitative storage control mechanism to move downwards. This causes the opening of the infeed / outfeed hopper 606 in the quantitative storage control mechanism to face downwards. At this time, the modified asphalt inside the anti-segregation storage chamber 703 enters the sealing cover 6 through the infeed / outfeed chute 601. Then, the controller 2 controls the infeed / outfeed drive motor 608 to reverse, and the infeed / outfeed drive motor 608 drives the infeed / outfeed drive shaft 609 to reverse through the infeed / outfeed drive reducer 607. The drive screw 610 is reversed, causing the modified asphalt to rotate and be squeezed into the feed hopper 604 and fall into the electric rotary discharge valve. Then, the electric rotary discharge valve 605 is controlled to work, and the modified asphalt is quantitatively discharged through the feed hopper 606. After the modified asphalt is discharged from one anti-segregation storage chamber 703, the anti-segregation drive motor 711 is controlled by the controller 2 to work, driving the anti-segregation storage chamber 703 to rotate, and quantitatively discharging the modified asphalt from the other anti-segregation storage chambers 703 in sequence.

[0114] By setting up a feeding and discharging tilting mechanism, a quantitative storage control mechanism, and a modified asphalt anti-segregation mechanism, when storing high-content rubber powder modified asphalt, the feeding and discharging tilting mechanism drives the quantitative storage control mechanism to rotate, facilitating feeding and storage of the modified asphalt and its subsequent discharge. During feeding and storage, the quantitative storage control mechanism controls the feeding and discharging quantities. Multiple anti-segregation storage chambers 703 within the modified asphalt anti-segregation mechanism separate the modified asphalt for separate storage, preventing the accumulation and compression of large quantities of modified asphalt, which leads to the sedimentation of floating matter and particles. During storage, the rotation of the anti-segregation storage chambers 703 keeps the modified asphalt inside in motion and mixed, and the stirring shaft 704 and stirring shovel 705 further agitate and mix the modified asphalt. This solves the problem of existing asphalt storage tanks used for storing and using high-content rubber powder modified asphalt, which often result in floating matter and large amounts of particle sedimentation, causing slow asphalt heating and segregation, thus affecting normal production.

After the feeding and discharging turning mechanism turns the quantitative storage control mechanism upward, the modified asphalt anti-segregation mechanism is fed with asphalt storage material. Specifically, when feeding modified asphalt storage material, the controller (2) controls the operation of the tilting drive motor (504). The tilting drive motor (504) drives the tilting drive worm (506) to rotate through the tilting drive reducer (503). The tilting drive worm (506) drives the drive worm wheel ring (501) to rotate.
