Asphalt melting device

Abstract

The invention provides an asphalt melting device, which comprises a tank body (3) and a bracket (11). The tank body (3) is arranged on the bracket (11); a transmission stirring device (1), a hot oil heating system (2) and an inner guide cylinder body (5) are arranged in the tank body (3); the lower end of the inside of a straight cylindrical section of the tank body (3) is welded with a support frame (10); and a stirring shaft (7) of the transmission stirring device (1), the hot oil heating system (2) and the inner guide cylinder body (5) are arranged on the support frame (10) inside the tank body (3). The asphalt melting device can ensure that the high-temperature asphalt can be quickly melted in short time, the liquid asphalt at a discharge hole of the device reaches the temperature of process requirement, asphalt clinker is easy to discharge, the power consumption of equipment is lowered, and the environment-friendly requirement is met.

Description

technical field [0001] The invention relates to an asphalt melting device. Background technique [0002] At present, in the production of electrolytic aluminum in my country, most of the anode carbon blocks of electrolytic aluminum use liquid pitch as the binder for batching in the carbon process configuration. During the process, the solid pitch must be heated and melted into liquid pitch at a certain temperature. The existing technology is to concentrate the solid asphalt in an asphalt heating tank for centralized heating, which is equivalent to boiling in a large pot. After 2 to 3 days, the asphalt can be completely melted, which is time-consuming, energy-consuming, and pollutes the environment. Good clean up. With the use of current density of anode carbon block products, the improvement of environmental protection requirements in the production process, and the need for large production capacity, the existing technology can no longer meet the production requirements. ...

With the use of current density of anode carbon block products, the improvement of environmental protection requirements in the production process, and the need for large production capacity, the existing technology can no longer meet the production requirements

[0003] In the prior art, the Chinese patent application number 200420117095.7 discloses an asphalt melter for industrial testing, which solves the shortcomings of the previous asphalt open flame heating and heating systems, and the Chinese patent application number 200520200703.5 discloses a mixer with spiral blades The asphalt melter solves the problem that the solid asphalt suspension cannot be melted. They involve partial solutions to the problems that occur during the asphalt melting process, but do not solve the time-consuming, energy-consuming, environmental pollution and slag deposited at the bottom of the tank when the asphalt is melted. Good cleaning and other issues
