Description

Technical Field

[0001] The utility model relates to the technical field of dissolving tanks, in particular to a dissolving tank for preparing a urea solution. Background Art

[0002] Urea solution is a liquid containing urea. Its main uses include as an additive for diesel engine SCR systems, as an ingredient in skin care products, and as an additive for diesel engine SCR systems. This urea solution is mainly used in SCR technology. Through selective catalytic reduction reactions, nitrogen oxides are converted into harmless nitrogen, oxygen and water, thereby reducing pollution to the environment. Urea solution nourishes the skin, keeps the skin hydrated, softens the stratum corneum, and isolates the skin from external adverse environmental pollution. It is suitable for treating dry skin, chapped skin, and other conditions. Urea solution has a therapeutic effect on conditions such as dry hands and feet, and can also play a skin care role, allowing the skin to maintain sufficient moisture.

[0003] A dissolving tank for preparing urea solution is disclosed in the Chinese utility model patent application disclosure CN217855898U. Although the utility model allows the staff to receive the material without holding the receiving bucket by hand, saving time and effort, the utility model needs to determine the density of the urea solution according to the specific purpose when preparing the urea solution. At room temperature, the density of automotive urea solution is about 1.08g / cm3. The automotive urea with too high density will cause the nozzle to be blocked or unable to spray well, resulting in a decrease in the efficiency of the SCR system and even affecting the performance of the entire vehicle. , resulting in a decrease in the urea content, thereby affecting the increase in density and reducing the efficiency of the vehicle's SCR system. Agricultural urea solution is usually configured in a ratio of 1:5. The device cannot measure the density of the urea solution, which affects the preparation quality and subsequent use of the urea solution. Therefore, there is a problem of not being able to measure the density of the urea solution. In addition, when the utility model prepares the urea solution, the urea particles dissolve in water, and the dissolution rate is slow, which affects the preparation speed. Therefore, there is a problem of slow dissolution rate. In summary, the utility model has the problem of not being able to measure the density of the urea solution and the slow dissolution rate.
