Problems solved by technology

[0002] Before the production of modified asphalt, the asphalt matrix needs to be heated, and then transported to the equipment for producing modified asphalt. The existing asphalt heating method is generally: the asphalt is passed into the inside of the tank, and the heat conduction oil pipe located inside the tank is used to heat the tank. Heating the asphalt in bulk, this heating method has a slow heating speed, the asphalt stays in the tank for a long time, and the heating efficiency is low, and the heating speed near the heat transfer oil pipe is fast, and the heating speed of the asphalt far away from the heat transfer oil pipe is slow, resulting in the asphalt in the tank The heating temperature is uneven, and it is not convenient to control the temperature of the asphalt through the heat conduction oil pipe

Abstract

The invention discloses an asphalt heating heat exchanger. According to the asphalt heating heat exchanger, asphalt pipelines in heating devices are used for conveying asphalt, heaters can heat the asphalt in the asphalt pipelines, and the asphalt pipeline is a spiral coil structure, such that the heating body of the heater can uniformly heat the asphalt in the asphalt pipeline, and the asphalt can be heated while being transported by the asphalt pipeline so as to increase the heating efficiency of the asphalt; through a plurality of the sequentially communicated heating devices, when the asphalt is heated, heating can be performed in a temperature-increasing manner, such that the condition that the one-time heating can cause the non-uniform heating of the asphalt so as to affect the heating effect can be prevented; and temperature control devices between the two adjacent heating devices are used for controlling the communication / disconnection of the communication pipes between the twoadjacent heating devices so as to conveniently control the uniform heating of the asphalt to a certain temperature, and if the asphalt temperature reaches the requirement, the heater after the temperature control device is closed. With the asphalt heating heat exchanger of the present invention, the temperature of the asphalt in the asphalt pipeline can be conveniently controlled.

Description

technical field [0001] The invention relates to the field of modified asphalt processing equipment, in particular to an asphalt heating heat exchanger. Background technique [0002] Before the production of modified asphalt, the asphalt matrix needs to be heated, and then transported to the equipment for producing modified asphalt. The existing asphalt heating method is generally: the asphalt is passed into the inside of the tank, and the heat conduction oil pipe located inside the tank is used to heat the tank. Heating the bitumen in bulk, this heating method has a slow heating speed, the asphalt stays in the tank for a long time, and the heating efficiency is low, and the heating speed near the heat transfer oil pipe is fast, and the heating speed of the asphalt far away from the heat transfer oil pipe is slow, resulting in the asphalt in the tank The heating temperature is uneven, and it is not convenient to control the temperature of the asphalt through the heat conducti...
