Problems solved by technology

[0004] It can be seen that the existing asphalt heating device adopts static heating, so the heating speed is slow and the heating is uneven, and the asphalt near the heating pipe of the heater is heated at high temperature for a long time, which is prone to asphalt aging
And if the heating time is long, the asphalt near the heating tube will be carbonized and deposited on the tube wall, and the heat exchange efficiency of the heater will decrease, resulting in increased energy consumption

Abstract

The invention discloses an asphalt heating device and asphalt stirring equipment which is provided with the asphalt heating device. The asphalt heating device comprises an asphalt tank (1) and a heating tank (2), wherein a first heater (25) is arranged in the heating tank; the asphalt tank (1) is provided with an asphalt outlet (11); the heating tank (2) is provided with an asphalt inlet (21) and an asphalt outlet (22); the asphalt outlet (11) of the asphalt tank (1) is communicated with the asphalt inlet (21) of the heating tank (2) through an oil supply pipeline (31); the asphalt heating device further comprises an asphalt pump (4) and a first reflux pipeline (32); the heating tank (2) further comprises an asphalt reflux port (23); the first reflux pipeline (32) is used for connecting the asphalt outlet (22) of the heating tank with the asphalt reflux port (23); and the asphalt pump (4) is connected in series to the first reflux pipeline (32). The asphalt heating device can be used for rapidly and uniformly heating asphalt, asphalt close to a heating pipe of the heater is prevented from ageing easily, and the energy consumption is low.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an asphalt heating device, and also to an asphalt mixing device with the asphalt heating device. Background technique [0002] Asphalt mixing equipment, also known as asphalt mixing equipment or asphalt mixing plant, is the key equipment for asphalt pavement construction. It is mainly used to measure and mix sand, gravel, asphalt and other materials into asphalt mixture after heating. Therefore, an asphalt mixing plant is usually equipped with an asphalt heating device for heating the asphalt. [0003] Existing asphalt heating device usually comprises asphalt tank and heating tank, has heater in heating tank, and described asphalt tank has asphalt outlet, and described heating tank has asphalt inlet and asphalt outlet, and the asphalt outlet of described asphalt tank is connected with described The bitumen inlet of the heating tank is connected through the oil supply pipelin...
