Energy-saving and environment-friendly asphalt heater

Abstract

The invention relates to an energy-saving and environment-friendly asphalt heater. The heater includes a heating cylinder. The axial direction of the heating cylinder is provided with a rotating shaft passing through the heating cylinder. The motor is connected, the drive motor, the reducer and the other end of the shaft are supported on the frame through bearings and bearing brackets. There is an interlayer on the wall of the heating cylinder, and a heat-conducting medium and a heater are arranged in the interlayer. There are import and export of raw materials. The energy-saving and environment-friendly asphalt heater can ensure that the elastic concrete mixed with asphalt and gravel is heated and stirred at a safe and controllable temperature, and can effectively control the mix ratio of elastic asphalt and gravel, greatly improving the performance of elastic concrete. Strong strength, so that the seams after construction will not crack or seep, and will not produce bagging in summer, ensuring smooth seams.

Description

Technical field [0001] The invention relates to the technical field of asphalt heating equipment, in particular to an energy-saving and environment-friendly asphalt heater. Background technique [0002] At present, in the construction of municipal roads, in road widening projects, the old bridges that can be used are generally old bridges and then spliced ​​into new bridges. Secondly, there are also a large number of splicing situations in the process of connecting new roads to the original roads. Due to the uneven settlement of the new and old bridges, the sudden height difference at the settlement joints will affect driving safety, and rainwater will seep along the cracks, corrode the beam structure, and affect the safety of the bridge structure. Therefore, the bridge construction and bridge construction of the bridge longitudinal joint A difficult problem in the maintenance process. In order to solve the problem of splicing joints, a material called elastic concrete is curren...

AI Technical Summary

Problems solved by technology

Since the elastic asphalt is solid at room temperature, a heatable container is usually used in construction at present, and it is heated with an open flame underneath. Because the temperature of combustion heating is not easy to control, the temperature is too low and it cannot be melted, and the temperature is too high. Molecular structure, elastic asphalt produces chemical changes, and at the same time, the proportion of crushed stone and elastic asphalt in the elastic concrete produced by mixing the melted elastic asphalt and gravel is not easy to control, which seriously affects the quality of construction, so it is urgent to solve the construction technology of elastic concrete , effectively control the two elements of temperature and mix ratio to ensure the construction quality
