Description

Technical Field

[0001] The utility model relates to the technical field of asphalt storage tanks, in particular to an asphalt storage tank for highway construction. Background Art

[0002] Asphalt is a complex, dark-brown mixture of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a highly viscous organic liquid that is liquid, black in surface color, and soluble in carbon disulfide. Asphalt is an organic cementitious material that provides water, moisture, and corrosion resistance. Asphalt can be primarily categorized as coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue from crude oil distillation. Natural asphalt is stored underground, sometimes forming deposits or accumulating on the Earth's surface. Asphalt is primarily used in industries such as coatings, plastics, and rubber, as well as in road paving.

[0003] The patent document with the existing authorization announcement number CN 219340476 U is an asphalt storage tank for highway construction, comprising an outer shell and a reduction motor, wherein a thermal insulation layer is provided on the inner wall of the outer shell, and a feed pipe and a vent pipe are respectively provided on both sides of the top of the inner shell, and the other ends of the feed pipe and the vent pipe pass through the thermal insulation layer and the outer shell in sequence and extend to the outside; this patent document enhances the fluidity of asphalt during storage and avoids the occurrence of agglomeration caused by the asphalt being in a static state for a long time.

By providing two temperature sensors 24, the detection area can be expanded to ensure that the asphalt is in a suitable temperature range. When the pressure of the tank shell 11 is within the control operating pressure range of the breathing valve 21, the breathing valve 21 does not work and maintains the airtightness of the tank shell 11. When asphalt is added to the tank shell 11, the gas in the upper part of the tank shell 11 is vented. When the pressure in the tank increases and reaches the positive operating pressure of the breathing valve 21, the pressure valve is pushed open and the gas escapes from the exhalation port of the breathing valve 21, so that the pressure in the tank shell 11 no longer continues to increase. When the tank shell 11 discharges asphalt, the pressure in the upper gas space in the tank shell 11 drops. When the operating negative pressure of the breathing valve 21 is reached, the atmosphere outside the tank shell 11 will push open the negative pressure valve disc of the breathing valve 21, allowing external gas to enter the tank, so that the pressure in the tank shell 11 no longer continues to drop, and the air pressure inside and outside the tank shell 11 is balanced, preventing the tank shell 11 from deformation.
