Surface modification atomizing device for stone materials butted to pitch mixing floor and control method thereof

Abstract

The invention discloses a surface modification atomizing device for stone materials butted to a pitch mixing floor and a control method thereof. The device comprises a control unit, a raw material bucket, a conveying pump, a first electronic switch, a second electronic switch, a first atomization spraying head device and a second atomization spraying head device, wherein the conveying pump is communicated with the first atomization spraying head device and the second atomization spraying head device through a first pipeline and a second pipeline; a first electric valve and a second electric valve are respectively arranged on the first pipeline and the second pipeline; the first atomization spraying head device is arranged at the upper part of a screening cabin; the second atomization spraying head device is arranged on a mixing cylinder; the conveying pump and the first electric valve are connected with a power supply through the first electronic switch; the conveying pump and the second electric valve are connected with the power supply through the second electronic switch; the first electronic switch and the second electronic switch are respectively connected with the control unit. For the device, the surface modification is carried out twice for the stone materials, great specific surface area can be reached, and surface modification agents of the stone materials can be fully and uniformly distributed onto the surfaces of the stone materials.

Description

technical field [0001] The invention relates to a stone surface modification device connected to an asphalt mixing plant, in particular to a stone surface modification atomization device connected to an asphalt mixing plant and a control method thereof. Background technique [0002] Stone is an important raw material for the construction of asphalt concrete roads, but high-quality stone that fully meets the performance requirements is very scarce. For this reason, a method for modifying the surface of the stone is proposed, and the performance that the stone lacks is modified to improve its defects. . Such as granite and other acidic stones are dense and hard, with strong wear resistance, which can fully exert the intercalation effect between stones and meet the requirements of wear resistance and bearing capacity of the surface layer of asphalt pavement. However, due to the weak interface adhesion with asphalt, There are often limitations in the application of the surface ...
