[0002] Automotive urea is an essential additive for the SCR solution. The SCR system includes a urea tank (loaded with diesel exhaust treatment fluid) and an SCR catalytic reaction tank. The operation process of the SCR system is as follows: when nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays diesel exhaust treatment fluid, and the diesel exhaust treatment fluid and nitrogen oxides undergo an oxidation-reduction reaction in the SCR catalytic reaction tank to generate pollution-free nitrogen and water vapor for discharge;

[0003] A blending tank is a tank used to mix and configure materials, also known as a configuration tank (preparation tank). It is mainly used for the formulation of food and dairy products, the preparation of liquids in the pharmaceutical industry, and the preparation of ingredients in the chemical, coatings and other industries.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] When automotive urea is prepared and configured through a blending device, pure water and urea need to be stirred together. However, the ratio of urea is 32.5% high-purity urea plus 67.5% high-purity water. Urea will precipitate into the water in the early stage and slowly mix with the water. The water cannot mix with the urea quickly, making it impossible for the blending device to quickly mix the urea and water at different positions.
