Description

Technical Field

[0001] The utility model relates to the field of vehicle urea liquid, in particular to a vehicle urea liquid storage tank. Background Art

[0002] Diesel exhaust treatment fluid, commonly known as: automotive urea, automotive urea, automotive environmentally friendly urea, diesel vehicle exhaust purification fluid, automotive urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards.

[0003] At present, a Chinese patent discloses a large-capacity automotive urea liquid tank, and its application number is 2023210215216. In the technical solution of this application, the urea liquid stored in the tank is mixed and stirred by the setting of a hybrid unit. The air pump introduces external gas into the tank through a branch pipe and an air guide head to mix and stir the urea liquid, thereby preventing the urea liquid from being statically shelved for a long time, which leads to a decrease in the concentration of the automotive urea liquid and affects the effect of its exhaust gas treatment. The risk of blockage or damage of the circulating pump during use is effectively avoided, and the maintenance and inspection costs of the circulating pump are saved. The air pump, branch pipe and air guide head play a role in efficiently mixing the urea liquid in the tank and mixing the urea liquid evenly.

[0004] In combination with the above-disclosed technical solution, since urea liquid will precipitate during storage, the quality of the urea liquid will decrease, and during storage, the urea liquid is easy to adhere to the inner wall of the tank, which is troublesome to clean up later and reduces work efficiency. Therefore, we propose a vehicle urea liquid storage tank to solve this problem. Utility Model Content
