Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt pipelines, in particular to an asphalt pipeline embedded in a heat transfer oil pipe. Background Art
[0002] Asphalt pipeline refers to a pipeline system used to transport closed substances such as asphalt. Asphalt is a high-viscosity, organic mixture that requires a certain temperature to maintain its fluidity during transportation. Therefore, asphalt pipelines are characterized by thicker pipe walls and higher requirements for pipeline materials. Asphalt pipelines are widely used in engineering construction, mainly in the construction of pavement concrete, transportation of oil and natural gas, and other fields.
[0003] As disclosed in a Chinese patent: an asphalt pipeline system, application number: CN202022680662.1, comprising an asphalt pipeline, wherein both ends of the asphalt pipeline are fixedly connected with connecting flanges, an outer shell is provided on the outside of the asphalt pipeline, both ends of the outer shell are fixedly connected to the connecting flanges, a detection ring is sleeved on the asphalt pipeline, electromagnetic heating rings are provided on both sides of the detection ring, an ultrasonic transmitter is provided in the upper end of the detection ring, an ultrasonic receiver is provided in the lower end of the detection ring, motors are fixedly connected to the outside of both ends of the outer shell, and a rotating shaft is fixedly connected to the output end of the motor. By arranging the detection ring on the asphalt pipeline and by arranging the outer shell on the outside of the asphalt pipeline, thermal insulation is improved and heat loss is reduced. At the same time, a motor is arranged on the outer shell, and the pull rope is reeled by the motor, and the detection ring is pulled to move along the asphalt pipeline, so as to detect and heat and dredge the asphalt pipeline, and the detection is comprehensive and easy to use.
[0004] However, in the above technical solution, the temperature has a great influence on the asphalt during the asphalt production process. The pipeline is a rigid part and will be displaced when heated. In order to heat the asphalt pipeline, most production units adopt the method of embedding the asphalt pipeline in the heat transfer oil pipe to form a casing to heat the asphalt. However, this asphalt heating method has a significant defect. When the asphalt pipeline is embedded in the heat transfer oil pipe, when the asphalt pipeline is broken, the asphalt will enter the heat transfer oil, affecting the quality of the heat transfer oil.
[0005] When the heat transfer oil pipe is heated, the asphalt in the pipe will be continuously heated, causing the asphalt in direct contact with the heat transfer oil pipe to coke due to the high temperature. On the one hand, it adheres to the asphalt pipe wall and affects the heating effect, and on the other hand, it affects the product quality of the asphalt.
[0006] Asphalt pipelines are rigid parts. When the pipeline is at the tank inlet or outlet, the pipeline will be deformed due to the sedimentation of asphalt, and in severe cases, it may cause the pipeline to break. Utility Model Content

A heat transfer pipe is provided on the outer wall surface of the asphalt pipe. A metal hose is wrapped around the outer wall of the asphalt pipe. A plurality of protective sheets are fixedly provided on the outer wall surface of the base.
[0010] Preferably, the winding distance interval of the metal hose is 5 cm.
[0011] Preferably, the heat pipe comprises a heat pipe base, a first groove is arranged on the heat pipe base, and a limiting baffle is arranged on one side of the heat pipe base.

[0016] (1) When the utility model is used, the metal hose is heated by the heat transfer oil pipe, and then the metal hose heats the asphalt pipe through the heat transfer pipe, thereby heating the asphalt in the asphalt pipe. When the asphalt pipe is broken, the asphalt will not enter the heat transfer oil pipe, and when the asphalt pipe needs to be repaired, the two metal guards are taken out from the first groove, and then there will be nothing blocking the outside of the asphalt pipe, so that it is convenient for the staff to repair the asphalt pipe, and the asphalt pipe can be repaired in time to reduce waste; and it avoids direct contact with asphalt, prevents coking, and ensures product quality; when the metal hose is used to connect the pipeline inlet or outlet, when the tank body sinks due to asphalt, the connected metal hose will deform accordingly according to the displacement, avoiding rigid brittle fracture and protecting the asphalt pipe and the heat transfer oil pipe.
