[0002] Urea, also known as carbon amide, is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is also called urea. It is a white crystal, one of the simplest organic compounds, a diamide of carbonic acid, with the molecular formula H2NCONH2(CO(NH2)2), molecular mass 60, and the main nitrogen-containing end product of protein metabolism and decomposition in mammals and some fish. In order to prevent urea from producing excessive NOx to pollute the environment, urea should be denitrified to form denitrified urea.

[0003] The existing denitrification urea needs to be measured during production, but the existing metering device will shake and become unstable during weighing, which affects the accuracy of weighing. After the denitrification urea is weighed, there will be residual urea on the scale plate, which will affect the weight during the next weighing.
