Description

Technical Field

[0001] This invention belongs to the field of asphalt recycling technology, specifically an asphalt recycling device for waste asphalt mixtures. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. It mainly exists in the form of tar or asphalt, with a black surface. It is soluble in carbon disulfide and is mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. It is mainly used in industries such as coatings, plastics, and rubber, as well as in road paving.

[0003] In existing technologies, common asphalt recycling devices mix asphalt with other materials after recycling to achieve recycling. Current separation technologies typically use machine blades for separation, which cannot separate iron impurities and other stone impurities from the waste asphalt, leading to resource waste. It's important to note that since the recycled asphalt waste is usually piled up in one place and not deliberately broken up during retrieval, some waste will not be completely shredded during separation, reducing the efficiency of subsequent cleaning. Therefore, we provide an asphalt recycling device for waste asphalt mixtures. Summary of the Invention

[0010] Preferably, the output shaft of the motor passes through the bottom of the cleaning tank and a rubber sealing ring is provided at the connection. The output shaft of the motor drives the outer ring to rotate through an internal gear and two gears. The rotational speed of the outer ring is less than the rotational speed of the motor output shaft.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 11 As shown, the present invention provides an asphalt recycling device from waste asphalt mixture, including a washing tank 1 and a splash guard 2 hinged to the top of the washing tank 1. The splash guard 2 is provided with a handle 3. A water outlet pipe 10 communicating with the interior of the washing tank 1 is provided at the bottom of the washing tank 1. A motor 4 is provided at the bottom of the washing tank 1. A balance ring 11 is installed in the internal bearing of the washing tank 1. The device also includes… The reduction gear assembly 8 is located inside the cleaning tank 1 and is connected to the motor 4 for transmission. The deceleration assembly 8 includes an outer ring 81 that is movably installed inside the cleaning tank 1; Separation component 5 is installed inside the cleaning tank 1; The separation assembly 5 includes a base plate 51, a main shaft 52, a cover plate 53, a spring plate 54, a belt 55, and a separation blade 56. The spring plate 54 is elastically connected to the base plate 51. The base plate 51 is hinged to the outer ring 81. The top of the base plate 51 is connected to the cover plate 53 through the main shaft 52 and the separation blade 56. The main shaft 52 is connected to the power conversion assembly 6 through a chain 9. The main shaft 52 is connected to the separation blade 56 through a belt 55. The belt 55 is movably engaged between the base plate 51 and the cover plate 53. Two differentiation components 7 are arranged circumferentially inside the cleaning tank 1; The separation component 7 includes a balance shaft 71 hinged to the top of the outer ring 81. A first splitter plate 72 and a second splitter plate 73 are movably mounted on the balance shaft 71. The second splitter plate 73 is elastically hinged to the outer ring 81 through a second spring plate 74. The power conversion component 6 is installed inside the cleaning tank 1. The motor 4 drives the separation component 5 and the differentiation component 7 to work through the reduction component 8 and the power conversion component 6.

[0021] The separation assembly 5 has three components except for the spring plate 54, which are arranged vertically. The three separation assemblies 5 are fixedly connected to each other. The upper cover plate 53 is hinged to the balance ring 11. The inner wall of the cleaning tank 1 has a number of separation grooves 13 equal to the number of separation assemblies 5. The separation blade 56 moves within the separation groove 13. The outer periphery of the belt 55 is provided with rubber protrusions and there is a gap between the belt and the inner wall of the cleaning tank 1.

[0022] The top of the balance shaft 71 is hinged to the balance ring 11. The inner wall of the cleaning tank 1 is provided with two intersecting wave grooves 12. The first diverter plate 72 and the second diverter plate 73 are respectively movable inside the two wave grooves 12.

[0023] Both the first flow divider 72 and the second flow divider 73 have slots of the same size, and blades are provided at both the upper and lower ends of the slots.

[0024] Using the above scheme: First, open the splash guard 2 by using handle 3, then pour water containing cleaning agent and waste asphalt into the cleaning tank 1. However, it should be noted that the waste asphalt must be located between the two separation components 7 and not in contact with the separation component 5. Then, the motor 4 can be started. The motor 4 drives the separation component 5 and the two separation components 7 to revolve around the center point of the output shaft of the motor 4 through the reduction component 8 and the power conversion component 6. As the two separation components 7 revolve, waste asphalt will accumulate on the protruding surface of the first separation plate 72. The first separation plate 72 and the second separation plate 73 begin to move according to the two corrugated grooves 12. Since the two corrugated grooves 12 are intersecting, the first separation plate 72 and the second separation plate 73 will move vertically in an intersecting manner. When the grooves on the first separation plate 72 and the second separation plate 73 overlap, the waste asphalt will enter the groove. When the first separation plate 72 and the second separation plate 73 move again and intersect, the blades in the groove will cut the asphalt. After the asphalt is separated by the two separation components 7, it will contact the separation component 5. The power conversion component 6 drives the main shaft 52 to rotate via the chain 9. The main shaft 52 then drives the belt 55 to rotate. The rubber protrusions on the belt 55 guide the water to flow onto the separating blade 56. It should also be noted that the asphalt will move with the water to the edge of the separating blade 56. As the base plate 51 continuously revolves around the center point of the output shaft of the motor 4, the asphalt will be squeezed by the base plate 51 and will be successfully contacted and separated by the separating blade 56. The separating blade 56 is located in the separating tank 13, which allows the waste asphalt to be separated better, thus facilitating subsequent cleaning and processing. When there is too much asphalt between the base plate 51 and the inner wall of the cleaning tank 1 and it accumulates, causing the separating blade 56 to be unable to perform the separation work smoothly, the spring plate 54 will bend and increase the gap between the base plate 51 and the cleaning tank 1. At this time, the asphalt can pass through the separating component 5 and reach the edge of the diverter plate 72. Similarly, when the gap between the diverter plate 72 and the cleaning tank 1 is not enough for the asphalt to pass through, the spring plate 74 will also bend and allow the asphalt to pass through smoothly. However, since the diverter plate 72 will move up and down according to the wave groove 12, the asphalt will not continue to accumulate. It is important to note that while the chopping process is underway, the asphalt, in conjunction with the separation component 5 and the differentiation component 7, continues to come into contact with water containing cleaning agents and rubs against each other. This process also filters and separates stone and iron impurities from the waste asphalt, further improving the efficiency of the device.

[0025] like Figure 3 , Figure 6 , Figure 9 , Figure 10As shown, the reduction assembly 8 also includes an internal gear 82 disposed inside the outer ring 81. Two gears 83 are disposed at the bottom of the outer ring 81. The two gears 83 mesh with each other. The two gears 83 are a sun gear and a planet gear, respectively. The sun gear is connected to the output shaft of the motor 4. The planet gear bearing is installed inside the cleaning tank 1 and meshes with the internal gear 82. The output shaft of the motor 4 passes through the bottom of the cleaning tank 1 and a rubber sealing ring is disposed at the connection. The output shaft of the motor 4 drives the outer ring 81 to rotate through the internal gear 82 and the two gears 83. The rotational speed of the outer ring 81 is less than the rotational speed of the output shaft of the motor 4.

[0026] The above scheme is adopted: the output shaft of motor 4 drives gear 83 to rotate, and another gear 83 is mounted on the cleaning tank 1. At this time, gear 83 will also drive inner gear 82 and outer ring 81 to rotate. Outer ring 81 drives separation component 5 and differentiation component 7 to rotate and work. However, the speed of outer ring 81 will be less than the speed of gear 83, so that separation component 5 and differentiation component 7 will not get stuck between the inner wall of cleaning tank 1 and the outer periphery of separation component 5 and differentiation component 7 due to excessive speed, thereby improving the smoothness of device operation.

[0027] like Figure 2 , Figure 3 , Figure 6 , Figure 9 , Figure 11 As shown, the power conversion assembly 6 includes two filter plates 61 fixedly installed at the upper and lower ends inside the cleaning tank 1. A transmission ring 62 is movably installed on the top of the filter plate 61. A second main shaft 64 is fixedly installed on the top of the sun gear. Two turbines 65 are respectively installed on the second main shaft 64.

[0028] There are three transmission rings 62 arranged vertically. Each transmission ring 62 is connected to the other by a support ring 63. All three transmission rings 62 are fixed on the second main shaft 64. The transmission rings 62 are connected to the first main shaft 52 by a chain 9.

[0029] The filter plate 61 and the support ring 63 together form a cavity. The top and bottom of the cavity are sealed by the inner wall of the cleaning tank 1. The support ring 63 has diamond-shaped slots at equal angles in the circumferential direction, and the transmission ring 62 has water grooves at equal angles in the circumferential direction on its outer periphery.

[0030] The interior of the cleaning tank 1 is filled with cleaning water and waste asphalt. The output shaft of the motor 4 drives the second main shaft 64 to rotate through the gear 83. The second main shaft 64 drives the two turbines 65 to rotate. The rotating turbines 65 draw water from the outside of the filter plate 61. The water enters the cavity and is sprayed into the interior of the cleaning tank 1 through the diamond-shaped slot.

[0031] Using the above scheme: the output shaft of motor 4 drives the second main shaft 64 to rotate through gear 83. At this time, the second main shaft 64 will drive each turbine 65 and the transmission ring 62 to rotate. The transmission ring 62 will drive the main shaft 52 to rotate through the chain 9, thereby enabling the separation component 5 to enter the working state. However, since the two gears 83 mesh with each other, and the outer gear 83 meshes with the inner gear 82, the rotation direction of the main shaft 64 is opposite to the rotation direction of the main shaft 52. That is, the rotation speed of the main shaft 52 increases, thereby better separating waste asphalt. During the rotation of turbine 65, it draws water from inside cleaning tank 1 into the chamber, while the asphalt is blocked by filter plate 61, thus preventing the separated asphalt threads from becoming entangled on main shaft 64 or turbine 65. After the water is drawn into the chamber, it will eventually be sprayed back into cleaning tank 1 through the diamond-shaped slot and water tank. Figure 9 As shown, the diamond-shaped groove and the opening of the water tank all face the chain 9. This ensures that the crushing of the lines in the asphalt by the water flow does not affect the transmission of the chain 9, further improving the smoothness of the device's operation.

[0032] Working principle and usage process of this invention: First, open the splash guard 2 by using handle 3. Then, pour water containing cleaning agent and waste asphalt into the cleaning tank 1. Note that the waste asphalt must be located between the two power conversion components 6 and not in contact with the separation component 5. Then, start the motor 4. The output shaft of the motor 4 drives the gear 83 to rotate. The other gear 83 is mounted on the cleaning tank 1. At this time, the gear 83 will also drive the inner gear 82 and the outer ring 81 to rotate. The outer ring 81 will drive the base plate 51 and the balance shaft 71 to rotate and work. Diverter plate 1 72 and diverter plate 2 73 start to move according to the two wave grooves 12 and move vertically in an alternating manner. When the grooves on diverter plate 1 72 and diverter plate 2 73 overlap, waste asphalt will enter the groove. When diverter plate 1 72 and diverter plate 2 73 move again and intersect each other, the blades in the groove will cut the asphalt. After the asphalt is separated by the two separation components 7, it will contact the separation component 5. The output shaft of motor 4 drives the second main shaft 64 to rotate via gear 83. At this time, the second main shaft 64 will drive each turbine 65 and the transmission ring 62 to rotate. The transmission ring 62 will drive the first main shaft 52 to rotate via chain 9. The main shaft 52 will drive the belt 55 to rotate. The rubber protrusions on the belt 55 guide the water to flow onto the separating blade 56. The asphalt will also move with the water to the edge of the separating blade 56. As the base plate 51 continues to revolve around the center point of the output shaft of the motor 4, the asphalt will be squeezed by the base plate 51 and will come into contact with and be separated by the separating blade 56. While the chopping process is underway, the asphalt, in conjunction with the separation component 5 and the differentiation component 7, continues to come into contact with water containing cleaning agent and rubs against each other, which can also filter and separate stone impurities and iron impurities in the waste asphalt. The water outlet pipe 10 is connected to an external water pipe. After the device has finished working, the asphalt in the cleaning tank 1 can be removed and the external water pipe can be turned on, at which point the water will be discharged.
