Asphalt recovery coating vibration reciprocating blender and asphalt coating process thereof

Abstract

The invention relates to an asphalt recovery coating vibration reciprocating blender and an asphalt coating process thereof. At present, the domestic and foreign asphalt mixing plants used in the rapid development of domestic highways all adopt direct heating which causes the defects of easiness in stone surface carbonization and poor coating. The asphalt recovery coating vibration reciprocating blender comprises a reaction kettle, a heat transfer oil filling station and a vibrator, wherein automatic heat-proof doors are arranged on two sides of the reaction kettle respectively; a discharging bin with a cold stirred material discharging port and a hot stirred material discharging port is arranged on one side of the reaction kettle; a cold stirred material-hot stirred material separating plate is arranged in the discharging bin; the heat transfer oil filling station is connected with a heat transfer oil pipe on an inner wall of the reaction kettle; the vibrator is arranged in the reaction kettle; and a shock-absorbing device is arranged at the bottom of the reaction kettle. The invention provides a special heating manner for milling and planing materials, in which the temperature is controlled within 190 DEG C, the mining and planing material as well as asphalt is heated, and the mining and planing material rolls over in a bin under the action of reciprocating vibration, so as to ensure sound adhesion and form a pre-coated recovery material.

Description

technical field [0001] The invention relates to a vibrating reciprocating agitator for leach restoration and coating and a leach coating process thereof. Background technique [0002] At present, most domestic and foreign asphalt mixing plants used in the rapid development of domestic highways use direct heating. Generally, oil is sprayed on the stone to make the stone heat up rapidly, reaching 160-190 degrees. It is sent into the asphalt mixing tank through the rotation of the drum, and mixed with the heated asphalt. Its advantage is that it heats up quickly, but the biggest disadvantage is that the surface of the stone is easy to carbonize, resulting in poor coating. Contents of the invention [0003] The technical problem solved by the present invention is to provide a vibrating reciprocating agitator with simple structure, low cost and simple process for leach recovery coating and its leach coating process. [0004] For solving above-mentioned technical problem, the t...
