Description

Technical Field

[0001] The utility model relates to the technical field of urea solution filling, in particular to urea filling equipment with a built-in heating structure. Background Art

[0002] Urea solution for vehicles is a urea aqueous solution that is a mixture of special raw materials for urea for vehicles and ultrapure water to a specific concentration. It can make the exhaust emissions of diesel vehicles such as heavy trucks or buses meet the National IV emission standards. Urea solution for vehicles is an indispensable product in the exhaust gas treatment process. The main way to obtain it is through self-service sales and filling machines for urea solution for vehicles. At the same time, when the temperature of urea solution for vehicles is lower than 30 degrees, urea will crystallize from the aqueous solution, so it is necessary to continuously increase its temperature through a heating device to keep the urea solution for vehicles in a normal state. When the existing urea filling equipment is in use, an instant heating device is usually set at the discharge end of the filling equipment to instantly heat the urea solution for vehicles to be filled. However, since the filling process of urea solution for vehicles is relatively rapid, the heating effect of the heating device on the urea solution for vehicles to be filled is limited, which results in a small amount of crystals in the urea solution for vehicles that has been filled.
