Embodiment Construction
[0038] The following is attached Figure 1-8 The application is described in further detail.
[0039] refer to figure 1 , is a convenient sample extraction device disclosed in the present application, including a connecting pipe 1 , a sampler 2 , a drive assembly 3 and a pump 4 . The connecting pipe fitting 1 is connected to the flange of the sampling pipe of the isomerization reactor, which is mainly used to prevent the escape of VOC waste gas in the isomerization reactor and to facilitate the removal of the sampler 2 and take it to the testing equipment for component testing. The sampler 2 communicates with the pump 4, and is also connected with the driving assembly 3 through a vacuum pipe 20, and is used for extracting the material in the isomerization reaction kettle. The drive assembly 3 is used to drive the sampler 2 to move up and down for sampling. The liquid suction pump 4 vacuumizes the sampler 2 to speed up the entry of the material in the isomerization reaction...

The invention relates to the field of methyl tetrahydrophthalic anhydride detection equipment, in particular to a sample extraction device facilitating sampling. The sample extraction device facilitating sampling comprises a connecting pipe fitting, a sampler and a driving assembly, the sampler comprises an outer shell, a heat insulation layer, an inner shell, a heat preservation layer, a sampling tank body and a sealing cover, and the heat insulation layer is formed between the outer shell and the inner shell; the thermal insulation layer is formed between the sampling tank body and the inner shell; the sealing cover is detachably connected to the outer shell in a sealed mode. The sealing cover is provided with a heating medium input pipe; the sealing cover is provided with a sampling pipe; the sealing cover is provided with a communicating pipe fitting; the communicating pipe fitting is detachably communicated with a vacuumizing pipe fitting; the vacuumizing pipe fitting is communicated with a liquid pump and is connected with the driving assembly. Sampling is rapid, heat preservation treatment is conducted on the sampling liquid, solidification of the sampling liquid is avoided, the transfer efficiency of the sampling liquid is improved, and therefore the overall detection efficiency and the production efficiency of methyl tetrahydrophthalic anhydride are improved.
Description
technical field [0001] The application relates to the field of methyltetrahydrophthalic anhydride detection equipment, in particular to a sample extraction device that is convenient for sampling. Background technique [0002] In the production of methyltetrahydrophthalic anhydride, reactors are inevitably used. Reactors are used to store materials, polymerize, isomerize, recover materials, and distill to remove impurities. An isomerization reactor is used in the production process of methyltetrahydrophthalic anhydride, and the isomerization reactor is a place for isomerization reaction to obtain crude methyltetrahydrophthalic anhydride. In the production process of methyltetrahydrophthalic anhydride, after the isomerization reaction is completed, it is necessary to sample and analyze the materials in the isomerization reactor. The crude methyltetrahydrophthalic anhydride detected and analyzed meets the detection standard before the next purification operation can be carried...
