Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, specifically to a reaction vessel for asphalt production. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. Modified asphalt is an asphalt binder made by adding external admixtures (modifiers) such as rubber, resin, polymer, finely ground rubber powder or other fillers, or by taking measures such as light oxidation processing of asphalt to improve the performance of asphalt or asphalt mixture.

[0003] Chinese patent discloses a reaction vessel for asphalt production, publication number CN211800814U, comprising a reaction vessel body and a reaction vessel cavity. A sampler is disposed outside the reaction vessel body, the sampler including a sampler cavity. A sampling tube is disposed within the reaction vessel, connecting the reaction vessel cavity and the sampler cavity. The sampling tube extends to the bottom of the reaction vessel cavity from the end furthest from the sampler. A first sampling valve is disposed between the sampling tube and the sampler. A sampling pump is connected between the first sampling valve and the sampler. A discharge pipe is connected to the sampler cavity, and a second sampling valve is disposed between the discharge pipe and the sampler. This technical solution has the advantage of convenient real-time sampling.

[0004] However, it still has the following drawbacks: the device uses a motor to drive the agitator to rotate, which in turn agitates the asphalt. However, the agitator's mixing range is very limited, resulting in poor mixing effect and affecting the quality of the finished product. Therefore, we propose a reaction vessel for asphalt production to solve this problem. Utility Model Content

At the same time, when the horizontal plate moves upward, it pushes the bottom layer of asphalt upward, and when the horizontal plate moves downward, it moves the upper layer of asphalt downward, promoting the mixing of the upper and lower layers of asphalt. By setting up a motor, square rod, mounting cylinder, stirring plate, horizontal plate, and scraper, starting the motor drives the mounting cylinder, stirring plate, and scraper to rotate, causing the stirring plate and scraper to stir the asphalt. At the same time, the scraper scrapes and cleans the inner wall of the tank, promoting the mixing of the asphalt on the outside and the asphalt in the middle. By setting up a shell, insulation cotton, and oil pipeline, hot oil is transported through the oil pipeline to heat and keep the asphalt warm. Attached Figure Description
