Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a conveying device for chemical intermediates capable of filtering impurities. Background Art

[0002] 1,4-Butynediol BYD is an important intermediate chemical raw material, widely used in the production of butanediol and its downstream products, and the main raw material of vitamin B6. 1,4-Butynediol BYD is usually transported using closed pipelines. The raw material of 1,4-Butynediol BYD contains impurities such as high copper ions (Cu 2+ ), in the prior art, the high copper ion (Cu 2+ ), a mixture of CH-90Na resin and water can be mixed with 1,4-butynediol BYD raw material to make CH-90Na resin and the impurity high copper ion (Cu 2+ ) reacts to form (R-COO)2Cu precipitate, which is then removed by filtration.

[0003] For example, the patent with publication number CN214744990U discloses a fine chemical liquid material conveying device, which belongs to the technical field of material conveying device. The key points of its technical solution are that it includes a sealable conveying container. When liquid material needs to be conveyed, the seal valve of the sealable conveying container is closed first, and then the discharge valve at the cone bottom of the sealable conveying container can be opened, and at the same time, the compressed air intake valve is opened, and the compressed air exhaust valve is closed. Finally, all the liquid to be conveyed is conveyed to the receiving container through the liquid conveying pipeline, and then the compressed air intake valve is closed, and the compressed air exhaust valve is gradually opened to release the pressure, thereby realizing the fine chemical liquid material conveying device. It can be used for material conveying between reactors in the intermediate links of fine chemicals, and can also be used for the addition of small doses of fine chemical raw materials. It has obvious advantages for materials with high hazards and small conveying volumes.
