Asphalt heating tank

Abstract

The invention relates to an asphalt heating tank. An inclined clapboard for dividing a tank body into an upper cavity and a lower cavity is arranged inside the tank body; in the lower cavity, a waste gas recovering hole is formed in the higher end of the clapboard, and a passage for communicating the upper and lower cavities is formed in the lower end of the clapboard; an electromagnetic valve is arranged on the passage; an electric steam generator is arranged at one end of the lower cavity, and a motor is arranged at the other end of the lower cavity; a support frame is arranged at one side of the electric steam generator, a heating tube arranged above the electric steam generator penetrates through the support frame and is connected and communicated with a heating coil wheel which is connected with a rotating shaft of the motor; a positioning plate is arranged between the heating tube and the support frame and covers a connecting interface between the heating tube and the heating coil wheel, and interface filler and a gasket are arranged at the interface. The asphalt heating tank disclosed by the invention is provided with the rotatable heating coil wheel to ensure that asphalt can be uniformly heated and prolong the service life of the heating tank, and the inclined clapboard avoids reduction of the quality of asphalt due to cold and hot oil mixing, and also avoids accumulation of the asphalt.

Description

technical field [0001] The invention relates to a heating device, in particular to an asphalt heating tank. Background technique [0002] Existing asphalt heating tanks are various, but each has certain defects. E.g: [0003] The preheating effect, heating effect, and heat preservation effect of the heating tank are not ideal. The melting speed of the asphalt in the heating tank is slow, which affects the fluidity of the asphalt. In order to ensure the fluidity of the asphalt in the production process, there are long heating times and energy Consumption and other problems, and because the asphalt is heated for a long time, the quality of the asphalt will be damaged; [0004] Some heating tanks are open, and with the heating of asphalt, some toxic gases are discharged into the atmosphere, which will seriously pollute the environment. poor; [0005] The heating part of some heating tanks is higher than the storage part of asphalt, and asphalt is easy to accumulate in the t...

AI Technical Summary

Problems solved by technology

[0003] The preheating effect, heating effect, and heat preservation effect of the heating tank are not ideal. The melting speed of the asphalt in the heating tank is slow, which affects the fluidity of the asphalt. In order to ensure the fluidity of the asphalt in the production process, there are long heating times and energy Consumption and other problems, and because the asphalt is heated for a long time, the quality of the asphalt will be damaged;

[0004] Some heating tanks are open, and with the heating of asphalt, some toxic gases are discharged into the atmosphere, which will seriously pollute the environment. poor;

[0005] The heating part of some heating tanks is higher than the storage part of asphalt, and asphalt is easy to accumulate in the tank; some heating tanks are directly heated by fire, and the heating part of the heating tank is easy to corrode, which reduces the service life of the heating tank;

[0006] Most heating tanks cannot heat the asphalt to the temperature required for asphalt heating, and rely on the mixing of hot and cold asphalt in the heating tank, which will affect the oil quality of the asphalt
