Asphalt mixture stirring device capable of automatically feeding fibers

Abstract

The invention discloses an asphalt mixture stirring device capable of automatically feeding fibers, fibers in a fiber asphalt mixture are uniformly distributed, and performance variability of the mixture is low. The invention discloses an asphalt mixture stirring device capable of automatically feeding fibers. The asphalt mixture stirring device comprises a liftable platform (6) with a supporting arm (8), a heating and stirring pot (61) arranged on the liftable platform (6), and a stirring blade (7) of which an upper end is connected with a gearbox (9) arranged at an upper end of the supporting arm (8), wherein a fiber bin (4) and a fiber stirring cavity (1) are further arranged at an upper end of the supporting arm; an upper opening of the fiber stirring cavity (1) is connected with a lower opening of the fiber bin (4), and a lower opening of the fiber stirring cavity (1) faces an upper opening of the heating and stirring pot (61); a fiber stirring blade (3) is arranged in the fiber stirring cavity (1), and an upper end of the fiber stirring blade (3) is connected with a fiber stirring motor (2).

Description

technical field [0001] The invention belongs to the technical field of building material preparation devices, and specifically provides an asphalt mixing device for automatic fiber input. Background technique [0002] Since the advantages of fibers can be fully utilized to greatly improve the performance of asphalt or asphalt mixtures, the research on high-performance fiber asphalt mixtures has received more and more attention. Different from the method of enhancing the pavement performance of asphalt mixture by improving the performance of asphalt binder, fiber asphalt mixture can give full play to the characteristics of composite materials, so that the functions of each component (fiber reinforcement and asphalt mixture matrix) can be fully utilized. In order to meet the higher requirements of asphalt mixture pavement put forward by factors such as external environment changes and complex stress states, and finally achieve the purpose of reducing pavement diseases and prol...

AI Technical Summary

Problems solved by technology

[0006] It can be seen from the structure and operation process of the above-mentioned asphalt mixture mixing device that fibers need to be added manually when making fiber asphalt mixture. Adding all the fibers at one time will easily lead to uneven mixing of the fibers, and the fibers are easy to adhere after adding asphalt At the mixing head, greatly increases the variability of the fibrous asphalt mix, negatively affecting its performance
