Abstract

The invention discloses a sampling device of polyether polyatomic alcohol in a storage can. The sampling device comprises a sampling can arranged on the lower end of the storage can; the upper end of the sampling can is connected with the lower end of the storage can through a connecting pipeline; a control valve is arranged on the connecting pipeline; the top of the sampling can is provided with an air inlet pipeline connected with nitrogen; an air inlet control valve is arranged on the air inlet pipeline; the bottom of the sampling can is provided with a circulating pipeline; the upper end of the circulating pipeline is connected with the storage can; a sampling port is arranged on the circulating pipeline; a sampling control valve is arranged in the sampling port; and a circulating control valve is arranged on the circulating pipeline. The sampling device has the advantages that the structure is skillful; the use is convenient; the sampling result can completely meet the requirements; no polyether polyatomic alcohol is wasted; and the sampling device is suitable for the sampling of the polyatomic alcohol and the sampling of various liquid matters in the storage can.

Description

Technical field [0001] The invention relates to a sampling device, in particular to a sampling device for polyether polyol in a storage tank. Background technique [0002] Usually polyether polyol is stored in a storage tank. In order to sample and analyze the polyether polyol in the storage tank, the current method is to directly set up a sampling pipeline at the bottom of the storage tank and control it through a valve. The valve needs to be opened when sampling and storage The polyether polyol in the tank will flow out of the pipeline to complete the sampling. The disadvantage of this sampling method is: because the front part of the sampling pipeline has a long part, to ensure accurate sampling, ensure that the sampled polyether polyol is free of impurities , The samples obtained after releasing a certain amount of polyether polyol can be representative. In this way, the more polyether polyol that flows out before sampling can only become waste or inferior products due to con...
