Asphalt concrete production device with novel screening structure and asphalt concrete production method

Abstract

The invention relates to the technical field of asphalt concrete production, and discloses an asphalt concrete production device with a novel screening structure. The asphalt concrete production device comprises a shell, the shell is provided with a base station, a crusher shell is fixedly arranged above the base station, a crushing device and vibration equipment are fixedly arranged in the crusher shell, and the vibration equipment is provided with a vibration plate; a first discharging plate is fixedly connected to the end, away from a first through hole, of the crusher shell, a stirring box is fixedly connected to the lower end of the first discharging plate, a supporting plate is arranged on one side of the stirring box, a discharging plate is connected to the side face of the heating box, a telescopic rod is fixedly connected between the discharging plate and the heating box, and a stirring device is arranged in the stirring box; and the outer side of the stirring device is fixedly connected with a scraper, and the lower part of the stirring box is fixedly provided with a discharge port. According to the asphalt concrete production device, the crushing device and the vibration equipment are arranged, so that broken stones are fully crushed by the production device, and asphalt is uniformly and fully heated by a heating device.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete production, in particular to an asphalt concrete production device with a novel screening structure and a production method of asphalt concrete. Background technique [0002] Asphalt concrete, commonly known as asphalt concrete, is artificially selected with a certain gradation composition of mineral materials, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, mixed under strictly controlled conditions made mixture. [0003] Asphalt concrete needs to crush gravel and other raw materials first, and then mix it with hot asphalt to obtain asphalt concrete. Asphalt and cold mineral powder are mixed, but the crushing device is insufficiently crushed, which will affect the subsequent asphalt concrete production effect; moreover, it is necessary to use other devices to pre-heat the asphalt and then transfer it to the ...
