Online sampling device for high-solid-content phosphoric acid

The utility model relates to the technical field of phosphoric acid sampling, in particular to an online sampling device for high-solid-content phosphoric acid, which comprises a main acid inlet pipe, an acid inlet pipe, a sampling component and an acid preparation tank, when a phosphoric acid solution in the acid preparation tank is sampled, phosphoric acid guided into the acid preparation tank can be automatically sampled in advance by means of cooperation of the main acid inlet pipe, the acid inlet pipe and the sampling assembly, and the phosphoric acid solution entering an acid storage tank can be fully and uniformly stirred through cooperation of a stirring motor and a stirrer in the sampling assembly; the uniformly stirred phosphoric acid solution has no concentration layering condition, so that the concentration error of the phosphoric acid sample introduced into the sampling barrel through the sampling pipe is further reduced, and the problem that the phosphoric acid in the acid preparation tank is ea
