Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt recycling, in particular to a waste asphalt recycling device. Background Art
[0002] Asphalt is a highly viscous organic liquid, mainly used in industries such as coatings, plastics, rubber, etc. and for paving roads. After long-term use, asphalt will be damaged. Since asphalt contains a large amount of other products harmful to the human body and the environment, it will cause environmental pollution. Therefore, it is necessary to recycle the damaged waste asphalt for reuse.
[0003] The asphalt applied to roads contains a large amount of stones. Therefore, existing asphalt recycling devices all heat and melt the asphalt in a tank and then filter it. It is difficult to filter the asphalt during the melting process, so the speed of asphalt recycling is slow. Moreover, during the filtering process of asphalt, due to the high viscosity of asphalt, a large amount of asphalt adheres to the surface of the filtered stones, reducing the recovery rate of asphalt. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a waste asphalt recycling device to solve the above deficiencies in the technology.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A waste asphalt recycling device includes a feed cover. One end outer wall of the feed cover is fixedly provided with a fixed shell. The inner wall of the fixed shell is fixedly provided with an interlayer cover. An electromagnetic heating coil is sleeved between the fixed shell and the interlayer cover. The inner wall of the fixed shell is fixedly provided with a metal filter screen cylinder. The metal filter screen cylinder is located inside the interlayer cover. One end outer wall of the feed cover away from the fixed shell is provided with a motor. The output shaft of the motor passes through the inner wall of the feed cover and is fixedly provided with a metal rotating rod through a coupling. The outer wall of the metal rotating rod is fixedly provided with a metal auger. The central axes of the metal rotating rod and the metal auger are on the same straight line as the central axis of the electromagnetic heating coil.
[0006] Preferably, one end outer wall of the feed cover is fixedly provided with a motor fixing cover, and the motor is fixed inside the motor fixing cover, which is convenient for fixing the motor on one side of the feed cover.
[0007] Preferably, one side of the top of the feed cover is installed with a feed hopper through an opening. One end of the fixed shell away from the feed cover is fixedly provided with a slag discharge port, which is convenient for discharging the filtered stones through the slag discharge port.
[0008] Preferably, one side of the bottom of the fixed shell away from the feed cover is communicated with a U-shaped discharge pipe through an opening. The central position of the bottom of the U-shaped discharge pipe is connected with a precipitation port through an opening. One side of the bottom of the precipitation port is screwed with a storage bottle. The precipitation port opened at the bottom of the U-shaped discharge pipe facilitates the precipitation of fine gravel and sand in the asphalt, and the storage bottle facilitates the storage of the precipitated sand and gravel.
