Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of urea solution preparation, in particular to an intelligent preparation device for vehicle urea solution. Background Art
[0002] Currently, there are two main methods for producing automotive urea solution. One is to mix automotive urea granules and high-purity water in a ratio of 32.5%. The other is to directly mix the urea molten solution produced during the urea production process with high-purity water in a certain ratio. Compared with the first production method, the method of directly mixing the urea molten solution has the advantages of simple process and low cost, which is mainly reflected in reducing the heat required for dissolving urea granules and reducing the steam consumption of urea solution to generate urea granules.
[0003] However, since the urea content of the final product remains unchanged, that is to say, the product quality of the above two production methods is the same, in the process of using urea solution in the treatment of diesel vehicle exhaust, the urea solution is mainly atomized by a urea pump, and then enters the premixer to mix with the diesel vehicle exhaust, and finally enters the catalyst side for reduction, reducing the nitrogen oxides in the exhaust gas into nitrogen and water. Automotive urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards, and is used to purify the exhaust gas of heavy-duty diesel vehicles. Automotive urea refers to a urea aqueous solution with a urea solution concentration of 32.5% and a solvent of ultrapure water. The raw materials are special raw materials for automotive urea and ultrapure water.
[0004] The above-mentioned problems have the following defects: during the preparation of automotive urea, urea raw material particles and liquid need to be fed into the inner cavity of the preparation device for stirring, mixing and preparation. During single stirring, after the urea and solution are mixed, some precipitates that are not dissolved in the solution will still exist, which will lead to uneven mixing and affect the purity of the final urea solution. Therefore, an intelligent preparation device for automotive urea solution is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a scraper, which is slidably connected to the inner walls on both sides of the stirring plate, the top outer wall of the scraper is fixedly connected to a sliding plate, and one side outer wall of the sliding plate is fixedly connected to a spring damper.

[0009] As a further description of the above technical solution: the preparation barrel is slidably connected to the inner walls on both sides of the frame, and the spur gear is fixedly connected to the output end of the first motor through a coupling.
