Description

Asphalt heating tank Technical field: The utility model belongs to the field of asphalt preparation, and particularly relates to an asphalt heating tank. The background technology is as follows: Asphalt is a blackish brown complex mixture composed of hydrocarbons of different molecular weights and nonmetallic derivatives thereof, is one of high-viscosity organic liquids, and exists mostly in the form of liquid or semisolid petroleum. The asphalt is mainly used as basic construction materials, raw materials and fuel, and has application range such as traffic transportation roads and railway construction. Taking asphalt for road and bridge construction as an example, the liquid asphalt needs to be continuously heated in the asphalt preparation process, so that the asphalt becomes soft and is easy to use in subsequent construction sites. In the prior art, the heating mode of liquid asphalt is generally to heat the heating medium oil body to a specified temperature through an external burner and then to convey the heating medium oil body into an asphalt heating tank through a circulating heating pipeline, so as to finish circulating heating of the liquid asphalt stored in the tank, the mode has lower cost input, but the distribution of the circulating heating pipelines arranged in the asphalt heating tank is single, mainly be the vertical U-shaped pipe of arranging in jar center department, lead to the local uneven heating of pitch heating jar, especially two distal ends are heated unevenly about pitch heating jar, and the heating rate is slow, and pitch heating efficiency is lower, if long-time continuous intensification heating also can cause the rising of energy consumption, pitch heating cost input is great. The invention comprises the following steps: The utility model aims to provide an asphalt heating tank, overcome the defects of the prior art, and effectively solve the existing problem of uneven heating of the asphalt tank. The utility model relates to an asphalt heating tank, which comprises an asphalt storage tank, wherein a feeding pipe and a discharging pipe are respectively communicated with the top and the bottom of the asphalt storage tank, two ends of the top of the asphalt storage tank are respectively communicated with a heat transmission pipe, the output ends of the heat transmission pipes are communicated with a distribution pipe, a plurality of arc heating pipes are uniformly communicated with the distribution pipe along the length direction, the arc tops of the arc heating pipes face to the arc surface of the asphalt storage tank, the bottom output ends of the arc heating pipes are communicated with a collecting pipe, the collecting pipe is communicated with a flow guide pipe, the output ends of the flow guide pipes are communicated with the bottom input ends of spiral heating pipes, and the top output ends of the spiral heating pipes extend out of the asphalt storage tank. Further, the spiral heating pipes are positioned in the middle of the two rows of arc heating pipes. Furthermore, a plurality of the arc heating pipes are distributed in a fishbone shape. Further, an elbow exhaust pipe is communicated with the top wall of the asphalt storage tank. Further, a temperature monitoring alarm is arranged on the top wall of the asphalt storage tank. The utility model has the beneficial effects that the spiral heating pipes and the arc heating pipes distributed on two sides are arranged in the inner cavity of the asphalt storage tank, so that the overall heating of asphalt is more uniform, the heating speed is high, the heating efficiency of asphalt is improved, and the cost is reduced.
