Description

Technical Field

[0001] The present invention relates to the technical field of colored asphalt preparation equipment, and particularly relates to a device for preparing colored permeable asphalt. Background Art

[0002] With the development of the economy and the acceleration of the urban construction pace, the surface of modern cities is gradually covered by reinforced concrete houses and impermeable concrete pavements. At present, the pavements of urban streets, sidewalks, bicycle lanes, parks, courtyards and public squares in China are mainly made of impermeable stone slabs and concrete. Although the paving technology of this kind of pavement is simple and the cost is low, it will bring many negative impacts to the urban ecological environment. First of all, this kind of impermeable and airtight pavement significantly reduces the rainwater infiltrating into the ground, and the urban groundwater cannot be replenished, damaging the urban water balance, affecting the growth of urban surface plants, and destroying the ecological balance of the urban surface. Secondly, this kind of surface-dense pavement cannot drain water in time on rainy days, causing water accumulation on the road surface, bringing many inconveniences to the travel of pedestrians and vehicles, increasing the urban noise pollution and forming the "heat island effect" of the city.

[0003] The technology of colored pavement laying can be traced back to the 1950s in European and American countries. The research on colored roads in China started in the early 1980s. However, due to the constraints of the economic conditions at that time and the small demand for colored binders, the progress was relatively slow. In recent years, with the rapid development of China's economy and people's continuous pursuit of beauty, the municipal construction has developed from simple practicality to sustainable development and coordination, which provides an opportunity for the development and use of colored binders. The traditional asphalt concrete pavement has a single color and is prone to cause visual fatigue of drivers. The colored pavement changes the monotonous and boring situation of the traditional road color. Its diverse and rich colors can be coordinated with the natural landscape, giving people a beautiful visual enjoyment. Applying colored permeable asphalt concrete pavement in urban roads can not only play the role of beautifying the environment, maintaining the ecological balance of the urban surface, and enhancing the urban image, but also has the function of guiding traffic and guiding vehicle flow; moreover, it can improve the driving safety of pedestrians and vehicles.

[0004] The Chinese Patent WeChat official account CN216572554U discloses a device for preparing uniformly mixed colored asphalt, including a box body. At the top of the left side of the box body, there is a stirring motor. The output shaft of the stirring motor penetrates the inner cavity of the box body and is equipped with a stirring shaft. On the outer surface of the stirring shaft, stirring rods are successively installed from left to right through couplings. At the bottom of the right side of the box body, there is a driving motor. The output shaft of the driving motor penetrates the inner cavity of the box body and is equipped with a driving shaft. The device turns on the stirring motor and the driving motor through an external controller, opens the sealing cover, and puts the materials to be mixed into the box body through the feed bin. The stirring motor drives the stirring rods to mix the materials through the stirring shaft, the first bearing, and the second bearing. At the same time, the driving motor drives the stirring paddles and the stirring rods to stagger up and down through the driving shaft, the first bearing sleeve, and the second bearing sleeve to mix the materials, which can mix the materials more evenly. However, in actual use, the device requires staff to pour different raw materials into the stirring mechanism in sequence. Since there are many raw materials required for preparing asphalt, simply relying on staff to pour the raw materials into the stirring mechanism has low efficiency, and the stirring mechanism is relatively high, which is not conducive to staff pouring the raw materials into the stirring mechanism.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Example 1. This example discloses a colored permeable asphalt, which is made by mixing components in the following proportions: 3-5% SBS modified asphalt, 80-82% coarse aggregate, 6-8% fine aggregate, and 5-7% colored high-viscosity additive; the mass ratio of the colored high-viscosity additive to the SBS modified asphalt is (7-11):(87-91); The colored permeable asphalt is prepared by the following method: Heat the SBS modified asphalt at 165-175 °C for 3.5-4.5 hours until it becomes a flowing state, and bake the coarse aggregate and fine aggregate at 180-185 °C for 4.5-5.5 hours for standby; Add the coarse aggregate and fine aggregate in the aggregate to the mixing pot, and dry mix for 16-19 s, with the mixing temperature at 175-185 °C; At 180-185 °C, while shearing, add the colored high-viscosity additive to the SBS modified asphalt. The addition ratio of the colored high-viscosity additive to the SBS modified asphalt is 8.94-12.90, and shear for 20-30 min until it is uniform and free of particles; After shearing, stir at 175-180 °C for 20-30 min to obtain a high-viscosity SBS modified asphalt; Add the coarse aggregate and fine aggregate in the aggregate to the mixing pot, and then add the high-viscosity SBS modified asphalt to the mixing pot, and mix for 90-180 s, with the mixing temperature at 180-190 °C; Finally, obtain the colored permeable asphalt, and control the discharge temperature of the mixture at 175-185 °C.

[0023] Furthermore, the colored high-viscosity additive is prepared by adding color powder to the high-viscosity additive HVA. The color powder is an inorganic pigment, and the inorganic pigment is a metal oxide or salt. The coarse aggregate is made of crushed diorite that is clean, dry and has a rough surface, with specifications of 2.5-4.5 mm and 4-9 mm, and the fine aggregate is made of diorite chips with a specification of less than 5 mm.

[0024] Example 2. This application also discloses a preparation device for producing this kind of colored permeable asphalt on the basis of Example 1, as Figure 1 and Figure 2As shown in the figure, it includes a mounting frame 1. On one side of the middle part of the upper end of the mounting frame 1, a stirring mechanism 2 is provided. On the other side of the middle part of the upper end of the mounting frame 1, a guide rail device 5 is provided. The middle part of the outer surface of the guide rail device 5 is fixedly connected to the upper end of the stirring mechanism 2. On one side of the upper end of the mounting frame 1, a transmission mechanism 3 is provided. A protective part 4 is fixedly installed at the upper end of the stirring mechanism 2. On the upper part of one side of the outer surface of the guide rail device 5, a feeding device 6 is slidably installed. The feeding device 6 is adapted to be used with the protective part 4. On the other side of the outer surface of the guide rail device 5, a hoist 7 is provided.

[0025] Further, as Figure 3 and Figure 4 shown in the figure, the protective part 4 includes a protective cover 41. The protective cover 41 is fixedly installed at the upper end of the stirring mechanism 2. On one side of the outer surface of the protective cover 41, a feeding protective frame 42 fixedly installed at the upper end of the stirring mechanism 2 is provided.

[0026] Specifically, during the process of asphalt preparation, staff or other devices pour raw materials into the inner cavity of the feeding device 6. Then, the output of the hoist 7 pulls the feeding device 6 to slide on the outer surface of the guide rail device 5. During this process, the feeding device 6 will gradually move upward. When the hoist 7 pulls the feeding device 6 to the corresponding height, the staff opens the feeding device 6 and pours the raw materials in the feeding device 6 into the inner cavity of the stirring mechanism 2. After that, the transmission mechanism 3 drives the stirring mechanism 2 to operate, so that the stirring mechanism 2 fully mixes the raw materials, thereby forming asphalt with corresponding properties. When the asphalt preparation is completed, the prepared asphalt in the inner cavity of the stirring mechanism 2 is poured out through the discharge port below the stirring mechanism 2.

[0027] Further, the protective cover 41 and the feeding protective frame 42 can, to a certain extent, prevent the raw materials in the inner cavity of the stirring mechanism 2 from splashing during the process of the stirring mechanism 2 preparing asphalt. At the same time, the feeding protective frame 42 then cooperates with the feeding device 6 to pour the raw materials into the inner cavity of the stirring mechanism 2.

[0028] During the process of asphalt preparation, it is necessary to transport the raw materials to the inner cavity of the stirring mechanism 2. During this process, if it is necessary for the staff to manually pour the raw materials into the inner cavity of the stirring mechanism 2, the work efficiency is relatively low. Therefore, it is necessary to quickly pour the raw materials into the inner cavity of the stirring mechanism 2 through the feeding device 6. During this process, it is necessary for the guide rail device 5 to limit the stroke of the feeding device 6. At the same time, the guide rail device 5 can also drive the feeding device 6 to operate, as Figure 5 and Figure 6As shown, the guide rail device 5 includes a guide rail plate 51, which is fixedly installed on one side of the middle part of the upper end of the mounting frame 1. The middle part of the outer surface of the guide rail plate 51 is fixedly connected to the upper end of the stirring mechanism 2. There is a mounting table 52 in the middle of the outer surface of the guide rail plate 51, a rack 53 is arranged in the middle of the outer surface of the guide rail plate 51 on the side far from the transmission mechanism 3, and a braking mechanism 54 is arranged in the upper part of the outer surface of the guide rail plate 51 on the side far from the transmission mechanism 3.

[0029] Further, as Figure 7 and Figure 8 shown, the braking mechanism 54 includes a motor 541, which is fixedly installed on the upper part of the outer surface of the rack 53. An installation disc 542 is arranged at the output end of the motor 541, and a plurality of transmission teeth 543 are arranged on the lower side end face of the installation disc 542.

[0030] Specifically, during the process of the hoist 7 pulling the material conveying device 6 upward, the material conveying device 6 will slide on the outer surface of the guide rail plate 51. At the same time, when the material conveying device 6 slides on the outer surface of the guide rail plate 51, the corresponding components in the material conveying device 6 are connected to the rack 53, so that the relevant components in the material conveying device 6 perform preliminary stirring on the raw materials placed in the inner cavity of the material conveying device 6.

[0031] Further, when the hoist 7 pulls the material conveying device 6 to a corresponding height, the corresponding components in the material conveying device 6 are connected to the braking mechanism 54. At this time, the braking mechanism 54 drives the corresponding components in the material conveying device 6 to operate, so as to quickly discharge the raw materials in the inner cavity of the material conveying device 6.

[0032] In order to quickly convey the raw materials into the inner cavity of the stirring mechanism 2, and at the same time, mix the raw materials during the conveying process, as Figure 9 shown, the material conveying device 6 includes a conveying hopper 61. There is a stirring member 62 in the middle of the inner cavity of the conveying hopper 61. Both ends of the stirring member 62 extend to the outside of the conveying hopper 61. A lifting member 63 is arranged on the outer surface of the conveying hopper 61 near the hoist 7. The lifting member 63 is connected to the output end of the hoist 7 through a steel wire rope. The lifting member 63 is slidably installed on the outer surface of the guide rail plate 51. An installation frame 66 is arranged at the lower part of the outer surface of the conveying hopper 61. A baffle 64 is arranged at the lower end of the conveying hopper 61 and is slidably installed on the inner cavity surface of the installation frame 66. The outer surface of the baffle 64 on the side far from the hoist 7 extends to the outside of the installation frame 66. A conveying frame 65 is slidably installed at the lower part of the installation frame 66. The outer surface of the conveying frame 65 is slidably connected to the inner side surface of the guide rail plate 51. The conveying frame 65 is used in adaptation with the feeding protection frame 42.

[0033] Specifically, before preparing the asphalt, the staff or other devices pour the raw materials into the inner cavity of the conveying hopper 61, and then the elevator 7 pulls the conveying hopper 61 to move obliquely upward on the outer surface of the guide rail plate 51. During this process, the stirring member 62 will reverse under the action of the rack 53, so that the stirring member 62 preliminarily stirs the raw materials in the inner cavity of the conveying hopper 61. At the same time, when there are lumps in the raw materials, etc., the stirring member 62 can break them up to a certain extent.

[0034] Further, when the elevator 7 pulls the conveying hopper 61 to the corresponding height, the conveying frame 65 is at the same height as the feeding protection frame 42. At this time, the staff can push the conveying frame 65 to slide, so that the conveying frame 65 enters the inner cavity of the feeding protection frame 42, and then fix the conveying frame 65. After that, the staff pulls out the baffle 64. At this time, the raw materials in the inner cavity of the conveying hopper 61 enter the inner cavity of the stirring mechanism 2 from the lower part of the conveying hopper 61 through the inner cavities of the conveying frame 65 and the feeding protection frame 42 under the action of gravity.

[0035] Further, after the elevator 7 pulls the conveying hopper 61 to the corresponding height, the corresponding components in the stirring member 62 are connected to the braking mechanism 54, and the braking mechanism 54 drives the stirring member 62 to rotate, so that the stirring member 62 rotates forward, so that the stirring member 62 continuously stirs the raw materials in the inner cavity of the conveying hopper 61. At the same time, during the feeding process of the conveying hopper 61, the forward-rotating stirring member 62 can improve the feeding efficiency of the conveying hopper 61.

[0036] In order to preliminarily mix the principles put into the inner cavity of the conveying hopper 61, as Figure 10 shown, the stirring member 62 includes two stirring rollers 621. The two ends of the two stirring rollers 621 extend to the outside of the conveying hopper 61. The outer surfaces of the two stirring rollers 621 on the side away from the rack 53 are connected by a transmission member. A braking member 622 is arranged on the outer surface of the stirring roller 621 on one side close to the rack 53, and a connecting member 623 is arranged on the outer surface of the stirring roller 621 on the other side close to the rack 53.

[0037] Further, the structure of the connecting member 623 is the same as the structure formed by the mounting disc 542 and the transmission gear 543, and the connecting member 623 is adapted to be used with the structure formed by the mounting disc 542 and the transmission gear 543.

[0038] Further, as Figure 11 shown, the braking member 622 includes a transmission rod 6221. A ratchet mechanism 6223 is arranged in the middle of the outer surface of the transmission rod 6221. One side of the outer surface of the ratchet mechanism 6223 is fixedly connected to one side of the outer surface of the stirring roller 621. A gear 6222 is arranged at the end of the transmission rod 6221 away from the stirring roller 621, and the gear 6222 is meshed with the rack 53.

[0039] Specifically, during the process of the hoist 7 pulling the material conveying device 6 upward, since the gear 6222 is meshed with the rack 53, during the upward movement of the conveying hopper 61, the gear 6222 drives the stirring roller 621 on one side to rotate through the ratchet mechanism 6223, and then drives the stirring roller 621 on the other side to rotate through the transmission member. Furthermore, during the rotation of the two stirring rollers 621, the stirring member 62 can stir the raw materials in the inner cavity of the conveying hopper 61. At the same time, since the stirring teeth on the stirring roller 621 are spaced relatively closely, the agglomerated raw materials in the inner cavity of the conveying hopper 61 can be broken up to a certain extent.

[0040] Furthermore, during the process of the hoist 7 pulling the material conveying device 6 to a certain distance before reaching the corresponding height, the connecting member 623 will gradually come into contact with the surface of the structure composed of the mounting plate 542 and the transmission gear 543. Then, when the motor 541 rotates, the two stirring rollers 621 can be driven through the connecting member 623, the mounting plate 542, and the transmission gear 543. During this process, since the gear 6222 and the rack 53 are always in a meshed connection, a ratchet mechanism 6223 needs to be provided so that when the motor 541 drives the stirring roller 621 to rotate, the ratchet mechanism 6223 will not drive the gear 6222 to rotate.

[0041] Furthermore, the structure of the ratchet mechanism 6223 is composed of a housing, a plurality of driving arc plates on the inner surface of the housing, and a special-shaped gear disk rotatably installed in the inner cavity of the housing. The special-shaped gear disk is fixedly connected to the transmission rod 6221. When the stirring roller 621 rotates, the stirring roller 621 will drive the housing in the ratchet mechanism 6223 to rotate. At this time, the plurality of driving arc plates on the inner surface of the housing will not drive the special-shaped gear disk to rotate, and thus the special-shaped gear disk will not drive the gear 6222. On the contrary, when the gear 6222 rotates, the special-shaped gear disk drives the housing to rotate through the plurality of driving arc plates on the inner surface of the housing, and then drives the stirring roller 621 to rotate.

[0042] Furthermore, the transmission member is composed of a belt mechanism and a gear set, so that the rotation directions of the two stirring rollers 621 are opposite.

[0043] It should be noted that the specific installation methods, circuit layout connection methods, and control methods of the transmission mechanism 3, the hoist 7, and the motor 541 used in the above-mentioned second embodiment are all conventional designs in the prior art, and will not be elaborated in detail in the present invention.

[0044] The foregoing has shown and described 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 by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
