Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture processing equipment, and specifically relates to an oil-stone separation device for waste asphalt mixture. Background Art

[0002] Asphalt mixture is the general term for the mixture formed by mixing mineral materials and asphalt binder. It is a composite material mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder. Recycling the waste asphalt mixture generated from asphalt pavement maintenance can reduce the construction cost of highways and the demand for oil and stone mining. Currently, an experimental prototype for oil-stone separation of waste asphalt mixture is generally used to recycle waste asphalt mixture through a series of operations such as leaching, filtering, cleaning, evaporation, separation, and recovery. By using this method, the waste asphalt mixture can be restored to asphalt and stone with its original properties, enabling it to regenerate new mixtures with various gradation requirements. In the prior art, when filtering asphalt mixture, a large amount of debris accumulates on the filter plate, and there is a lack of scraping and cleaning of the debris on the surface of the filter plate, resulting in a deteriorated subsequent filtering effect.

[0003] For example, the asphalt mixture disclosed in the authorized patent document with the application number CN202122350878.6 is the general term for the mixture formed by mixing mineral materials and asphalt binder.

[0030] In a further preferred embodiment, collection boxes 7 are embedded on both sides of the mixing box 1, and filter screens 8 are embedded on one side of the two adjacent collection boxes 7.

[0031] In this embodiment, waste asphalt mixture is introduced into the funnel 21, and the waste asphalt mixture is heated by the annular heater 22. The annular heater 22 will not transfer too much heat to the four support rods 10. After reaching a certain temperature, the control valve is opened, and the waste asphalt mixture falls into the filter frame 4 in the mixing box 1. The impurities are intercepted on the filter frame 4, and the motor 51 is started to drive the cam 52 to rotate. The rotation of the cam 52 will continuously impact the filter frame 4 to squeeze and stretch the return spring 53, and at the same time drive the sliding rod 9 to slide in the mixing box 1, playing a role of reciprocating swing on the filter frame 4 to improve the filtering effect. And two cylinders 62 are started. The two cylinders 62 are synchronous cylinders 62. The movement of the moving frame 63 will drive the scraping plate 64 to move. When the bottom of the scraping plate 64 contacts the surface of the filter frame 4, the scraping plate 64 will rotate, thereby promoting the stretching and squeezing of the spring device 65 in the moving frame 63. The inclined scraping plate 64 continuously scrapes on the surface of the filter frame 4, scraping the impurities from the filter frame 4 into the collection box 7. The surface of the collection box 7 is embedded with a filter screen 8, so as to further let the remaining asphalt enter the mixing box 1.

[0032] The driving member 5 includes a motor 51 fixedly installed on one side of the inner wall of the mixing box 1. The output end of the motor 51 is provided with a cam 52, and one side of the cam 52 is attached to the surface of the filter frame 4. Two return springs 53 are clamped on both sides of the filter frame 4, and one end of the return spring 53 is clamped on the inner wall of the mixing box 1;

[0033] Specifically, the motor 51 is started to drive the cam 52 to rotate. The rotation of the cam 52 will continuously impact the filter frame 4 to squeeze and stretch the return spring 53, and at the same time drive the sliding rod 9 to slide in the mixing box 1, playing a role of reciprocating swing on the filter frame 4 to improve the filtering effect.

[0034] Two sliding rods 9 are fixedly installed on both sides of the filter frame 4. The surface of the sliding rod 9 is slidably installed inside the mixing box 1, and the surface of the sliding rod 9 is movably sleeved inside the return spring 53;

[0035] Furthermore, the sliding rod 9 is set to slide in the mixing box 1 to enhance the stability of the movement of the filter frame 4.

[0042] In order to facilitate the collection of the asphalt remaining on the impurities at the filtration site, the bottoms of the inner walls of the two collection frames 7 are both set to be inclined.

[0043] This device imports waste asphalt mixture into the funnel 21 and heats the waste asphalt mixture through the annular heater 22. The annular heater 22 will not transfer too much heat to the four support rods 10. After reaching a certain temperature, the control valve is opened, and the waste asphalt mixture falls into the filter frame 4 in the mixing box 1. The impurities are intercepted on the filter frame 4. Then, the motor 51 is started to drive the cam 52 to rotate. The rotation of the cam 52 will continuously strike the filter frame 4, squeezing and stretching the return spring 53, and at the same time driving the sliding rod 9 to slide in the mixing box 1, playing a role of reciprocating swing for the filter frame 4 to improve the filtration effect. Then, the two cylinders 62 are started. The two cylinders 62 are synchronous cylinders 62. When the moving frame 63 moves, it will drive the scraping plate 64 to move. When the bottom of the scraping plate 64 touches the surface of the filter frame 4, the scraping plate 64 will rotate, thereby promoting the stretching and squeezing of the spring device 65 in the moving frame 63. The inclined scraping plate 64 continuously scrapes on the surface of the filter frame 4, scraping the impurities from the filter frame 4 into the collection frame 7.
