Abstract
Description
Technical Field
[0001] The utility model relates to an asphalt impregnation tank, belongs to the technical field of material impregnation, and is particularly suitable for an asphalt impregnation process in the corrugated asphalt tile manufacturing industry. Background Art
[0002] Asphalt is an organic cementing engineering material. It has good adhesion, plasticity, waterproofness and moisture resistance, and is therefore widely used in industry, transportation, water conservancy and civil engineering construction. Asphalt has been used as an engineering material for a hundred years. Asphalt is an extremely complex mixture of high molecular hydrocarbons and derivatives of chlorine, nitrogen and sulfur. It has poor fluidity and thermal conductivity. At room temperature, asphalt only ages quickly on the surface, but it accelerates aging above 130°C and undergoes qualitative changes above 180°C. Asphalt has good fluidity only at a temperature of 160-170°, which is suitable for storage and transportation of asphalt. It is particularly important to choose a heating method so that asphalt can maintain its original performance characteristics after heating.
[0003] At present, asphalt heating mostly uses natural gas to heat asphalt. However, the heating effect is not good, the heating efficiency is low, the heat conduction effect is poor, and measures should be taken to prevent asphalt aging and safe production during the heating process. In addition, the current device uses heating oil as the heating medium, which can obtain a higher temperature at a lower operating pressure. It has high thermal efficiency and is easy to automatically control the temperature. The asphalt is heated evenly, but the speed is slow, the contact area with the asphalt is small, the entire line is short, and the product cooling effect is not good; the entire asphalt pool is located below the horizontal plane, which is inconvenient to maintain and complicated to clean.

The length of the heat transfer oil pipeline is gradually shortened from the upper layer to the lower layer to adapt to the cross-sectional shape of the asphalt impregnation tank. The inlet and outlet of the heat transfer oil pipeline are both set on the uppermost layer of the heat transfer oil pipeline and are respectively located on the iron plates on both sides of the asphalt impregnation tank, thereby forming a loop. A temperature control valve is also set on the outlet of the heat transfer oil pipeline to detect the outlet temperature of the asphalt, thereby controlling the amount of heat transfer oil added to the heat transfer oil pipeline to ensure a constant asphalt temperature.
