Modified asphalt stirring device

Abstract

The invention discloses a modified asphalt stirring device which comprises a stirring tank. A feeding port is formed in the top of the stirring tank, a discharging port is formed in the side wall of the bottom of the stirring tank, a stirring motor is arranged in the middle of the top of the stirring tank and connected with a speed reducer, a stirring shaft is connected on a rotating shaft of thespeed reducer and extends into the stirring tank, screw blades are arranged on the stirring shaft, a temperature meter is arranged on the side wall of the stirring tank, a first high-temperature brakevalve and a second high-temperature brake valve are arranged on two opposite side walls of the stirring tank, a access hole is formed in the side wall of the bottom of the stirring tank opposite to the discharging port, and the discharging port is connected with the input end of a finished product conveying pump. By the aid of the high-temperature brake valves, the temperature of the stirring tank can be changed by inputting external heat, mixed and stirred states of asphalt and modifying agents are improved by improving the temperature, stirring of the stirring blades is accelerated, mixed uniformity of the asphalt and the modifying agents are further improved, dead corners in the stirring process are omitted by the aid of the stirring blades, and stirring efficiency and production efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of stirring devices, and in particular relates to a modified asphalt stirring device. Background technique [0002] Modified asphalt is a polymer made of matrix asphalt and modifier after repeated grinding and stirring. In the prior art, when preparing modified asphalt, the modifier and asphalt need to be mixed at a certain high temperature. Therefore, the asphalt and modifier are usually injected into the mixing tank after heating the asphalt first, so that the asphalt and modifier can be quickly and evenly mixed and compatible under heat preservation. Since the asphalt is in a molten state during the mixing process and has a certain viscosity, the mixing state of the asphalt cannot be changed under a fixed heat preservation condition. To improve the uniformity of asphalt mixing, the mixing time can only be prolonged, so the mixing efficiency is remarkable. reduce. Contents of the invention [0003] In ...
