Technical Field

[0001] The utility model relates to the technical field of asphalt production equipment, in particular to a heat-conducting oil heating asphalt scale and an asphalt gravity pipe. Background Art

[0002] A heated asphalt scale is a device used to measure heated asphalt materials. During road construction and maintenance projects, asphalt must be kept at a certain temperature to maintain its fluidity and ensure smooth paving. A heated asphalt scale not only maintains the required temperature but also accurately measures the required weight, which is crucial for ensuring construction quality and conserving materials. Existing asphalt scales lack a heating function. This can cause the asphalt to solidify while waiting to be unloaded, making it difficult to discharge. This results in asphalt waste and damage to the scale.

[0003] Asphalt scales typically discharge directly, with the flow rate controlled by a discharge valve on the discharge pipe. Due to the viscosity of asphalt, the discharge valve can become blocked and easily damaged, resulting in inaccurate control of the asphalt discharge volume. Traditional asphalt scales used in asphalt stations feature electrically heated structures, spray pipes, and asphalt pumps. These complex structures require advanced installation and operation skills, resulting in high equipment costs and low efficiency.

[0004] Therefore, there is an urgent need to design a thermal oil heated asphalt scale and an asphalt gravity pipe to solve the problems of easy solidification of asphalt in the existing asphalt scale, difficulty in controlling the discharge volume, and high pumping cost. Utility Model Content
