Abstract

The invention discloses an asphalt tank heating method. An asphalt tank is separated into a heating region, a dehydration region and a heat-preservation region; the heating temperature of the heating region is greater than the heating temperature of the dehydration region; the heating temperature of the dehydration region is greater than the heating temperature of the heat-preservation region; an asphalt outlet of the asphalt tank is located at the heating region. The invention further provides the asphalt tank and asphalt agitating equipment. The requirements on utilization functions of the asphalt tank are met; the heat energy is saved and the heating speed is improved; asphalt is prevented from being aged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an asphalt tank heating method, an asphalt tank and asphalt mixing equipment. Background technique [0002] With the continuous development of the asphalt industry, various polymer-modified asphalts have appeared. Modified asphalt is to add SBS, SBR, EVA, PE and other modifiers to ordinary base asphalt to increase the thermal stability and crack resistance of asphalt. . It has the advantages of increasing the adhesion between asphalt and stone and making asphalt have new mechanical properties. In the process of asphalt modification, not only the performance of asphalt is improved, but also the physical properties of asphalt are changed. The viscosity of asphalt is from the original maximum of 2000cst at 135 degrees Celsius to the current maximum of about 3000cst to 4000cst at 180 degrees Celsius. The viscosity increases. It is required to increase the spreading temperature,...
