Instant heating type asphalt tank with heat preservation function

Abstract

The invention discloses an instant heating type asphalt box with a heat preservation function, which mainly comprises an asphalt box body used for heating asphalt and preserving heat and an electric control system used for controlling heating temperature, and the asphalt box body is divided into an asphalt box inner cavity and a hearth through a box body bottom plate; a combustor is arranged at the position, corresponding to the hearth, of the asphalt box body, flames are jetted into the hearth through the combustor so as to heat asphalt in an inner cavity of the asphalt box, and a chimney extending out of the asphalt box body is arranged in the hearth. The top of the asphalt tank body is provided with an asphalt tank oil filling port and an oil suction pipeline extending downwards to the bottom of an inner cavity of the asphalt tank, the outlet end of the oil suction pipeline is connected with a pneumatic three-way valve through an asphalt pump and a driving module, and the two outlet ends of the pneumatic three-way valve are connected with an asphalt oil outlet pipeline and an asphalt oil return pipeline respectively. A heat-conducting oil heating mechanism for improving the asphalt heating efficiency is arranged on the asphalt tank body; and a heat preservation layer is arranged on the outer wall of the asphalt box body.

Description

technical field [0001] The invention relates to the field of road construction and maintenance machinery, in particular to an instant hot asphalt tank with heat preservation function. Background technique [0002] In the process of road construction and maintenance, asphalt is a commonly used road construction material. In the production of asphalt mixed roads and the maintenance of damaged asphalt pavements, liquid asphalt is usually sprayed into the road construction materials for uniform mixing before construction. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material, which is used in coatings, plastics, rubber and other industries as well as road paving. Asphalt is a black or dark brown viscous liquid, semi-solid or solid at normal temperature. In order to make it liquid for construction, it is usually necessary to heat the asphalt, especially in winter when the temperature is low. The existing asphalt heating device generally heats the as...

Problems solved by technology

The disadvantages of the above heating methods are: the asphalt is heated unevenly, the asphalt near the heating device may be overheated and aged, while the asphalt far away from the heating device cannot be heated, and the temperature of the asphalt rises slowly. Although the oil bath heating speed is fast, it is not suitable for mass use still not applicable when asphalt
