Description

Technical Field

[0001] The utility model relates to the technical field of solution stirring, in particular to stirring equipment for producing vehicle urea solution. Background Art

[0002] Automotive urea solution can convert nitrogen oxides in automobile exhaust into harmless nitrogen and water, which is both energy-saving and environmentally friendly, and makes vehicle exhaust meet national emission standards.

[0003] At present, the most effective means to reduce diesel vehicle exhaust emissions is to use a vehicle exhaust treatment solution made of 32.5% high-purity automotive urea and 67.5% ultrapure water to neutralize the nitrogen oxide pollution in diesel vehicle exhaust to meet emission standards. However, when producing automotive urea solution, 32.5% high-purity automotive urea and 67.5% ultrapure water need to be mixed and dissolved. The existing mixing method is simply stirring through a stirring rod. When the water temperature is low, the urea dissolution efficiency is low, which affects the production efficiency and easily produces urea crystals on the outer surface of the stirring rod.
