Description

Technical Field

[0001] The utility model is applicable to the technical field of asphalt production, and particularly relates to an asphalt heating device. Background Art

[0002] At present, when testing the quality and composition of asphalt, a corresponding heating mechanism is often used to heat and soften the originally solidified asphalt sample, thereby facilitating subsequent testing of the asphalt sample.

[0003] However, nowadays, when the solidified asphalt sample is placed inside the heating box for heating and melting, the solidified asphalt will gradually soften into a liquid state, and such asphalt will adhere to the inner wall of the heating box when it is inside the heating box, affecting the amount required for subsequent testing and sampling, and it is impossible to remove the material adhered to the inner wall of the box when the asphalt is removed from the heating box. Therefore, we propose an asphalt heating device. Utility Model Content

[0010] By adopting the above technical solution, the stirring blades are connected by driving through the rotating rod, so that the melting speed of the asphalt sample can be improved.

[0011] As an optional solution to the technical solution of the present application, the surfaces of both sides of the sealing cover are vertically fixed with feed pipes, and both ends of the bottom side of the insulation tank are horizontally fixed with cleaning and drain pipes, and the sides of the cleaning and drain pipes are connected to the outer side of the bottom of the heat transfer tank.

[0012] By adopting the above technical solution, the cleaning and drainage treatment of the inside of the heat transfer tank is achieved through the connecting function of the cleaning drainage pipe.

[0013] As an optional solution of the technical solution of the present application, heating rods are fixedly installed on the inner surface of the heat preservation tank, the number of the heating rods is several groups, and the heating rods are located outside the heat conduction tank.
