Modified asphalt mixing tank with scraper plate

Abstract

The invention discloses a modified asphalt mixing tank with a scraper plate. A modified asphalt mixing tank container is internally and longitudinally provided with a main shaft, wherein a propeller is arranged at the end part, positioned in the modified asphalt mixing tank container, of the main shaft, a shaft sleeve sheathes the outer part, close to the upper section, of the main shaft, a bearing is arranged between the main shaft and the shaft sleeve, a transmission gear sleeve sheathes the position close to the upper end on the shaft sleeve, the position close to the lower end of the shaft sleeve is connected with the scraper plate in the modified asphalt mixing tank container, and longitudinal scraper blades of the scraper plate are attached to the inner wall of a cavity of the modified asphalt mixing tank container, the lower end of the main shaft is positioned in the modified asphalt mixing tank container, and the upper end of the main shaft is connected with a belt pulley. According to the invention, double stirring power devices and a coiled tube type heating device are adopted, asphalt is uniformly mixed by virtue of stirring position and stirring speed; the modified asphalt mixing tank is rapid in heat conduction, and asphalt heating is uniform; the arrangement of a scraper-blade stirring system can be used for effectively preventing coking of the inner wall. The modified asphalt mixing tank is reasonable in integral design and ingenious in conception, has good practicability, and is easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of industrial asphalt mixing equipment, in particular to a modified asphalt mixing tank with a scraper, and in particular to its mechanical connection structure. Background technique [0002] Reference document, patent number: CN201320621405.8, patent name: stirring device for mesophase pitch preparation, patentee: Lunan Coal Chemical Research Institute, application date: 2013.10.10, this case discloses a mesophase pitch The stirring device of the stirred tank for preparation includes a threaded pipe that feeds clean compressed gas into the stirred tank and a round pipe connected in series at the lower end of the threaded pipe. There are at least three "V"-shaped section plates in a circular array on the circumferential wall of the round tube. The length direction of the "V"-shaped section plate is consistent with the axis direction of the round tube. The two sides of the "V"-shaped section plate are welded...

AI Technical Summary

Problems solved by technology

Due to the high viscosity and poor fluidity of the reaction materials in the kettle, there is a temperature difference between the inside and outside, the stirring effect of this blade type agitator is limited, and it is easy to coke on the inner wall of the stirred tank
