Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt concrete recycling, in particular to a separation device for asphalt concrete. Background Art
[0002] Asphalt concrete is a building material made of a mixture of mineral materials, asphalt and appropriate additives. The main raw materials include aggregates, asphalt and fillers. It is usually used in places such as roads and airport runways. As asphalt concrete ages after large-scale use, the recycling and reuse of asphalt concrete has become very important.
[0003] Since asphalt concrete is a hard material formed by tightly squeezing aggregates through the bonding force of asphalt, it is difficult to separate the asphalt by ordinary screening. Therefore, the recycled asphalt concrete needs to be separated by a separation device. However, when separating the asphalt, the existing asphalt concrete separation device usually only uses the centrifugal force generated by mechanical rotation to throw the asphalt out. Since the asphalt in the asphalt concrete is mostly tightly adhered to the aggregates, it is not easy to separate the asphalt from the aggregates in the concrete, resulting in a poor effect of separating the asphalt from the concrete. In addition, since the viscosity of the asphalt is higher after heating, the asphalt separated by heating is easy to adhere to the inner wall of the separation device, resulting in a slower flow rate after the asphalt is separated from the concrete, which is not conducive to the removal of the separated asphalt from the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 4 As shown, the present embodiment is used for the separation device of asphalt concrete, comprising an outer shell 5, an opening 16 is provided at the top of the outer shell 5, a vertical cylinder 3 is provided on the inner side of the opening 16, a mesh cylinder 7 is fixedly connected to the bottom end of the vertical cylinder 3, asphalt concrete 8 is placed inside the mesh cylinder 7, a heat conducting plate 9 is fixedly connected to the bottom end of the mesh cylinder 7, a rotating plate 10 is provided at the bottom of the heat conducting plate 9, a scraper strip 11 is engaged with the outer wall of the rotating plate 10, a gentle slope 15 is fixedly connected to the bottom of the inner side of the outer shell 5, a rotating motor 13 is fixedly installed at the bottom of the outer shell 5, electric heaters 12 are fixedly installed on both sides of the rotating motor 13, and a discharge hopper 6 is passed through the bottom of one side wall of the outer shell 5.
[0024] Specifically, the outer shell 5 is cylindrical in shape, with a hollow structure inside and a smooth inner wall, which is not easy to produce much adhesion with the fluid asphalt, so that the asphalt thrown on the inner wall of the outer shell 5 by centrifugal force can quickly flow along the inner wall of the outer shell 5 to the gentle slope 15, thereby shortening the time for the asphalt to flow in the device. The top of the vertical cylinder 3 is not closed, and the diameter of the vertical cylinder 3 is the same as the diameter of the net cylinder 7. In addition, the outer diameter of the vertical cylinder 3 is matched with the inner diameter of the sealing ring 4 inside the opening 16, so that the vertical cylinder 3 can pass through the top of the outer shell 5 and prompt the net cylinder 7 at the bottom to extend into the outer shell 5. At the same time, the vertical cylinder 3 can connect the top of the net cylinder 7 with the outer shell 5, so that the net cylinder 7 can maintain better stability when rotating with the rotating plate 10. The outer wall of the net cylinder 7 is provided with a plurality of mesh holes, so that the melted asphalt in the asphalt concrete 8 can be thrown out of the net cylinder 7 under the action of the centrifugal force generated by the high-speed rotation of the net cylinder 7. , thereby facilitating the separation of asphalt from concrete. The diameter of the heat conducting plate 9 is the same as that of the rotating plate 10, and the heat conducted by the electric heater 12 to the rotating plate 10 can be transferred to the asphalt concrete 8 in the mesh tube 7, so that the asphalt in the asphalt concrete 8 melts and becomes fluid, thereby facilitating the separation of asphalt from aggregate in the concrete. The scraper 11 is made of silicone material, with a smooth and wear-resistant surface. It can rotate along the slope of the gentle slope 15 as the rotating plate 10 rotates, thereby facilitating the asphalt separated on the gentle slope 15 to accelerate to flow to the discharge hopper 6. The rotating motor 13 can drive the rotating plate 10, so that the rotating plate 10 drives the heat conducting plate 9 and the mesh tube 7 to rotate at a high speed in the outer shell 5, so that the mesh tube 7 generates centrifugal force to throw out the asphalt in the asphalt concrete 8. The discharge hopper 6 can make the separated fluid asphalt flow out of the device quickly, thereby facilitating the rapid removal of the separated asphalt.
[0025] Furthermore, a connecting ring 2 is sleeved on the top of the vertical cylinder 3, and a top cover 1 is provided on the top of the connecting ring 2. The connecting ring 2 facilitates the holding of the vertical cylinder 3, so that the vertical cylinder 3 can be pulled out from the top of the outer shell 5 to take out the aggregate remaining after the asphalt concrete 8 in the mesh cylinder 7 is separated. The top cover 1 can keep the top of the outer shell 5 closed, so that the heat generated inside the outer shell 5 can be maintained in an optimal state, which is beneficial to the heat absorption and melting of the asphalt in the mesh cylinder 7.
[0026] Furthermore, a side wall of the top cover 1 is rotatably connected with a vertical rod 17, and the vertical rod 17 is fixedly connected to the outer shell 5. The top cover 1 is movably connected to the connecting ring 2 through the vertical rod 17. The vertical rod 17 can enable the top cover 1 to rotate in the horizontal direction, so that the horizontal height of the top cover 1 remains unchanged, and at the same time, the top cover 1 can remain connected to the outer shell 5, and it is also convenient to confirm whether the heat conduction plate 9 is correctly engaged with the rotating plate 10. If it is not correctly engaged, the top cover 1 rotated to the top of the vertical tube 3 along the horizontal direction cannot cover the top end of the vertical tube 3.
[0027] Furthermore, a sealing ring 4 is embedded in the inner wall of the opening 16, and the sealing ring 4 is movably connected to the vertical tube 3. The sealing ring 4 can reduce the gap between the opening 16 and the vertical tube 3, so that the top of the inner side of the outer shell 5 remains relatively sealed, so as to help the asphalt absorb the heat in the outer shell 5 and accelerate melting.
[0028] Furthermore, a clamping hole is opened at the bottom end of the heat conducting plate 9, and a clamping column 14 is fixedly connected to the top of the rotating plate 10. The heat conducting plate 9 is movably clamped and connected with the clamping column 14 at the top of the rotating plate 10 through the clamping hole. The inner diameter of the clamping hole is adapted to the outer diameter of the clamping column 14, so that the heat conducting plate 9 can be clamped on the rotating plate 10, thereby realizing the rotation of the heat conducting plate 9 driven by the rotating plate 10.
[0029] Furthermore, the output end of the rotating motor 13 is fixedly connected to the bottom end of the rotating plate 10, and the rotating plate 10 is rotatably connected to the outer shell 5. The rotating plate 10 can be driven to rotate by the rotating motor 13, so that the rotating plate 10 drives the heat conduction plate 9 and the mesh tube 7 to rotate at high speed, so that the asphalt concrete 8 inside the mesh tube 7 is separated by the centrifugal force generated by the high-speed rotation.
[0030] Furthermore, the rotating plate 10 is movably connected to the gentle slope 15, and the scraper bar 11 is movably connected to the gentle slope 15 through the rotating plate 10. The scraper bar 11 can rotate in accordance with the surface of the gentle slope 15 while the rotating plate 10 rotates, thereby facilitating the acceleration of the separated fluid asphalt to flow to the discharge hopper 6, and facilitating the rapid removal of the separated asphalt from the separation device.
[0031] The method of using the present embodiment is as follows: before using the separation device for asphalt concrete 8, it is necessary to first connect the separation device to an external power supply, and then pour the asphalt concrete 8 to be separated into the vertical cylinder 3, and then the asphalt concrete 8 entering the vertical cylinder 3 will fall onto the heat conducting plate 9 at the bottom of the net tube 7, and then the heat conducting plate 9 is passed through the sealing ring 4 at the top of the outer shell 5, so that the net tube 7 passes through the sealing ring 4, and when the clamping hole at the bottom of the heat conducting plate 9 is engaged with the clamping column 14 at the top of the rotating plate 10, the vertical cylinder 3 will fit with the inner wall of the sealing ring 4, and then the top cover 1 is horizontally rotated to the top of the vertical cylinder 3 through the vertical rod 17, and the tube mouth at the top of the vertical cylinder 3 is closed, and then the electric heater 12 and the rotating motor 13 are started, so that the rotating motor 13 drives The rotating plate 10 rotates, driving the heat conducting plate 9 engaged with the rotating plate 10 to rotate, and driving the mesh tube 7 to rotate at high speed in the outer shell 5 through the vertical tube 3, so that the asphalt concrete 8 in the mesh tube 7 begins to throw out asphalt under the action of centrifugal force. At the same time, the electric heater 12 transfers heat to the asphalt concrete 8 in the mesh tube 7 through the rotating plate 10 and the heat conducting plate 9, so that the asphalt melts and accelerates separation from the aggregate in the concrete, and passes through the mesh holes of the mesh tube 7, and then is thrown on the inner wall of the mesh tube 7. Then, the melted asphalt in a fluid state will slide along the inner wall of the outer shell 5 to the gentle slope 15. At the same time, the scraper bar 11 that rotates in contact with the gentle slope 15 accelerates the scraping of the separated asphalt off the surface of the gentle slope 15, so that the separated asphalt quickly flows out of the discharge hopper 6.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
