A high softening point oxidized asphalt mixing process

Abstract

The invention relates to the technical field of asphalt reaction equipment, in particular to a high softening point oxidized asphalt reactor. The high softening point oxidized asphalt reactor comprises a box, a rotating mechanism, a displacement mechanism, a discharge mechanism, a main stirring rod, a winding wheel, a first auxiliary stirring mechanism and a second auxiliary stirring mechanism; the high softening point oxidized asphalt reactor can actively stir asphalt in three dimensions by the main stirring rod, the first auxiliary stirring mechanism and the second auxiliary stirring mechanism, so that heating preparation efficiency of the asphalt is higher; when processing is completed, the main stirring rod can be retracted into a first storage tank under the driving of a third rotarymotor, and the first auxiliary stirring rod and the second auxiliary stirring rod can be retracted into a second storage tank, thereby realizing storage protection for the stirring rod and reducing floor area without blocking up and down movement of the discharge mechanism; the displacement mechanism can drive the discharge mechanism to move downward, so that the asphalt is completely extruded through a bottom plate, and the asphalt can be further scraped off an inner wall of the box through a triangular scraper block to reduce residues and increase discharge speed.

Description

technical field [0001] The invention relates to the technical field of asphalt reaction equipment, in particular to a high softening point oxidized asphalt mixing process. Background technique [0002] Oxidation method is one of the main methods of asphalt production. Oxidation method can significantly improve the high temperature performance of asphalt products; in the process of asphalt oxidation reaction, the asphalt oxidation reactor is very critical; the existing asphalt oxidation reactor generally includes The kettle body of the outlet and the discharge port is equipped with a motor-connected agitator driven by a motor and a vent line. [0003] When the asphalt reacts, the flowability is poor. When discharging, the discharge speed is very slow, and some asphalt will adhere to the inner wall of the reactor, causing waste, and it needs to be cleaned later, which is troublesome; the floor space of the mixer The large size makes the operating space for workers smaller dur...

[0003] When the asphalt is reacting, its circulation is poor. When discharging, the discharge speed is very slow, and some asphalt will adhere to the inner wall of the reactor, causing waste, and it needs to be cleaned later, which is troublesome; the floor space of the agitator Larger, making the operator's operating space smaller during maintenance, affecting maintenance efficiency
