Environment-friendly asphalt melting furnace for road repairing

Abstract

The invention belongs to the technical field of road repairing equipment and in particular relates to an environment-friendly asphalt melting furnace for road repairing. Aiming at the technical problems that a general asphalt heating furnace is simple in design structure, single in function, inconvenient to use and poor in environment friendliness, the following scheme is provided. The environment-friendly asphalt melting furnace comprises a bottom plate, wherein a box body is welded on one side of an outer wall of the top of the bottom plate; a motor is fixed in the center of an outer wall onthe top of the box body by virtue of bolts; an output shaft of the motor penetrates through the box body to be welded with a transmission shaft; stirring rods in annular distribution in equal distance are welded on the outer wall, which is close to one side of the motor, of the transmission shaft; spiral blades are welded at one end, which is far away from the motor, of the transmission shaft; the same heat-conducting plate is welded on the inner walls on two opposite sides of the box body; a rectangular through hole is formed in a position, which is close to the heat-conducting plate, of theinner wall on one side of the box body. The environment-friendly asphalt melting furnace disclosed by the invention is practical and novel, melting of asphalt can be accelerated, and the working efficiency is improved. Moreover, asphalt fume produced by molten asphalt and waste heat produced by gas burning can be fully utilized, and the asphalt melting furnace is energy-saving and environmentallyfriendly.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to an environment-friendly asphalt melting furnace for road construction. Background technique [0002] At present, asphalt is used for heating and melting in various construction projects such as oilfield construction, general construction and municipal engineering, and road construction. In the past, open-type asphalt melting equipment was used, which consumes a lot of energy, has low efficiency, and billows black smoke. The smell is smoky, and the particles in the flue gas are directly discharged into the atmosphere, which contains a large amount of carcinogenic benzoic acid, which is very harmful to the human body and pollutes the environment. [0003] After retrieval, the Chinese patent authorization number is CN201720723882.3, which discloses an asphalt heating furnace, including an asphalt melting furnace, a heating device and a flue gas treatment device. ...
