Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt paving technology, specifically to an asphalt mixture cooling device. Background Technology
[0002] Asphalt mixtures are mainly used for road and pavement construction. Asphalt mixtures are a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate and mineral powder. Sometimes polymers and wood cellulose are also added. By mixing these materials of different qualities and quantities, different structures are formed and different mechanical properties are achieved.
[0003] Temperature control is indeed necessary during the production and construction of asphalt mixtures to ensure their quality. Excessive temperature can lead to asphalt aging and reduce the performance of the mixture. Dispersion cooling devices can help asphalt mixtures to cool down evenly during transportation and storage. Current cooling equipment mainly uses fans for air cooling, which has poor cooling speed, uneven temperature, and poor practicality. Alternatively, manual stirring and separation of lumps in the asphalt mixture is required, which not only increases the workload of the testing personnel but also makes their work inconvenient. Moreover, once the asphalt remaining in the device has cooled, it is difficult to clean.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5This utility model provides a technical solution: It includes a housing 1, a mounting bracket 2 connected to one side of the housing 1, a drive motor 3 connected to one side of the mounting bracket 2, the output end of the drive motor 3 extending through into the housing 1 and connected to a rotating shaft 4, a stirring mechanism 5 connected to both ends of the rotating shaft 4, a cleaning mechanism 6 connected to the inner side of the stirring mechanism 5, a heat sink 7 connected to the outer surface of the housing 1, and heating tubes 8 sleeved and connected to both ends of the heat sink 7. A temperature sensor is located on one side of the housing 1; as this is a standard and necessary feature, it is not described in detail in the specification. Multiple heat exchange tubes 9 are sleeved and connected to the middle of the heat sink 7, and one end of each heat exchange tube 9 is connected to a common water inlet pipe. 10. A booster pump 11 is connected to the other end of the water inlet pipe 10. A water tank 12 is connected to the water inlet end of the booster pump 11. Support frames are connected to the bottom of both the front and rear ends of the housing 1. Fixed support frames 15 are rotatably installed on both sides of the rear support frame. Movable support frames 16 are rotatably installed on both sides of the front support frame. A connecting block 17 is rotatably installed on one end of each movable support frame 16. A push cylinder 18 is connected to one side of the connecting block 17. A feed hopper 21 is connected to the top of the housing 1. A base plate 151 is connected to the bottom end of the fixed support frame 15. The water tank 12 and the push cylinder 18 are both fixedly installed on the top of the base plate 151 to provide stability for the whole device.
[0023] Reference Figure 1 and Figure 2 As shown, a horizontal plate 13 is connected to the top of the water tank 12, and a cooling fan 14 is connected to the top of the horizontal plate 13. The other end of the heat exchange tube 9 extends into the water tank 12. After the booster pump 11 draws out and discharges into the heat exchange tube 9, the water absorbs heat by circulating around and then discharges back into the water tank 12. Then the cooling fan 14 can be turned on to cool down the water in the water tank 12 and ensure the heat absorption effect.
[0024] Reference Figure 5 As shown, a fitting frame 19 is connected to one side of the connecting block 17, and guide rails 20 are connected to both sides of the water tank 12. The fitting frame 19 is slidably connected to the guide rails 20. When the cylinder 18 extends and pushes the connecting block 17, the fitting frame 19 provides a limiting effect and movement stability for the connecting block 17, thereby pushing the movable support frame 16 to rotate, causing the shell 1 to tilt, which facilitates material discharge.
[0025] Reference Figure 3As shown, the mixing mechanism 5 includes an inner rotating plate 51 and an inner rotating plate 52 fixedly installed at both ends of the rotating shaft 4. A mixing crankshaft 53 is connected between the inner rotating plate 51 and the inner rotating plate 52. A discharge baffle 54 is rotatably installed on one side of the inner rotating plate 52, and a telescopic rod 55 is rotatably installed on one side of the discharge baffle 54. The other end of the telescopic rod 55 is rotatably installed on one side of the inner rotating plate 52. The cleaning mechanism 6 is slidably connected to the mixing crankshaft 53. When the drive motor 3 is started, the rotating shaft 4 is rotated, thereby rotating the inner rotating plate 51 and the inner rotating plate 52. The mixing crankshaft 53 located on the inner side mixes the asphalt mixture to cool it evenly. After mixing is completed, the discharge baffle 54 is rotated and opened by the retraction of the telescopic rod 55 to discharge the material.
[0026] Reference Figure 4 As shown, the cleaning mechanism 6 includes an outer ring frame 61 slidably disposed within the housing 1. An adjusting frame 62 is rotatably disposed within the outer ring frame 61. A through hole 63 is provided on one side of the adjusting frame 62. An installation groove is provided on the inner side of the outer ring frame 61, and an electric push rod 64 is connected to the installation groove. A limit block 65 is connected to the output end of the electric push rod 64. A limit groove is provided on the outer ring of the adjusting frame 62 corresponding to the limit block 65. When the stirring mechanism 5 is stirring, the electric push rod 64 retracts, causing the limit block 65 to be pulled out of the limit groove, allowing the adjusting frame 62 to rotate within the outer ring frame 61. Thus, the adjusting frame 62 can rotate together with the stirring mechanism 5. Protruding ends are provided on both sides of the outer ring frame 61, and sliding grooves are provided on the inner wall of the housing 1 corresponding to the protruding ends. After stirring is completed, the electric push rod... 64. Push the limiting block 65 into the limiting groove to connect the outer ring frame 61 and the adjusting frame 62. Due to the protruding ends on both sides of the outer ring frame 61, the cleaning mechanism 6 will not rotate with the mixing mechanism 5. However, the mixing crankshaft 53 will move the cleaning mechanism 6 through its own curvature. When mixing is needed, the through hole 63 can be positioned below. When the cleaning mechanism 6 moves as a whole, the rods between the through holes 63 are all chamfered, as can be seen from the attached figure, to reduce movement resistance and also to achieve a certain effect of mixing and combing the asphalt mixture. When discharge is needed, the through hole 63 is positioned above, and the asphalt is pushed out using the adjusting frame 62. At the same time, the asphalt adhesion on the inner wall of the shell 1 can be greatly reduced, reducing residue.
[0027] The implementation principle of this application is as follows: When using this utility model, high-temperature asphalt mixture is fed into the shell 1 through the feed hopper 21. Then, the drive motor 3 is started to drive the cleaning mechanism 6 to stir, and at the same time, the heat is transferred to the heat dissipation frame 7. The booster pump 11 is started to discharge water into the heat exchange tube 9. After the heat dissipation frame 7 is heated, it is discharged back into the water tank 12. The water in the water tank 12 is cooled by the horizontal plate 13. After the cooling is completed, the cylinder 18 is pushed to extend and push the connecting block 17 to lift the movable support frame 16, so that the shell 1 is cleaned as a whole. Then, the discharge baffle 54 is opened by the telescopic rod 55. At the same time, the stirring mechanism 5 drives the cleaning mechanism 6 to move along the shell 1 to facilitate the discharge of the asphalt mixture. During the discharge, the shell 1 can be heated by the electric heating tube 8 to maintain the optimal use temperature of the asphalt. As a safety device, it prevents the fluidity from decreasing due to the low temperature. Moreover, during the later cleaning, the electric heating tube 8 can be started to heat the shell 1, so that the residual asphalt in the shell 1 softens and is easier to clean.
