Sampling device for detecting acid content of maleic anhydride rich solvent by n-butane method

The utility model discloses a sampling device for detecting the acid content of maleic anhydride rich solvent by an n-butane method, which comprises a sampling underframe plate, a support mounting rack is arranged on the upper surface of the sampling underframe plate, the support mounting rack is connected with a discharge bottle through a snap ring, a sampling bottle is arranged right below the discharge bottle, and the sampling bottle is connected with the discharge bottle through the snap ring. According to the anti-blocking sampling device for the maleic anhydride rich solvent prepared by the n-butane method, the flow guide connecting sleeve rotates to drive the flow guide jacking shaft to jack up and open the discharge port, so that the blockage at the discharge port is avoided, the sampling efficiency is improved, and the sampling device is suitable for large-scale popularization and application. And manual cleaning and dredging are avoided, the labor intensity of workers is reduced, the work progress i
