A hydrofluoric acid liquid transfer device and transfer method

Abstract

The invention relates to a hydrofluoric acid liquid transfer device and a transfer method. The device comprises a reciprocating conveying mechanism, a storage box, and a box taking mechanism, whereinthe storage box is used for loading hydrofluoric acid liquid, is borne on the reciprocating conveying device, and is driven to move by the reciprocating conveying device; the box taking mechanism takes down the storage box from the conveying tail end of the reciprocating conveying mechanism; the reciprocating conveying mechanism comprises a driving chain wheel arranged at the conveying initial end, a driven chain wheel arranged at the conveying tail end, and chains sleeving the driving chain wheel and the driven chain wheel; the chains comprise pin shafts, and links connected with all the pinshafts from two ends of the pin shafts; and two ends of the pin shafts extend out, and are fixedly sleeved with link blocks. The device needs no manual intervention in the transfer process, can monitor if hydrofluoric acid in the storage box is leaked in the transfer process, is provided with double layers of seals for effectively preventing leakage of the hydrofluoric acid liquid to the terminal,and solves the defect of possible damage of workers in traditional transfer of the hydrofluoric acid.

Description

technical field [0001] The invention relates to the technical field of acid preparation, in particular to a hydrofluoric acid liquid transfer device and a transfer method. Background technique [0002] Due to its ability to dissolve oxides, hydrofluoric acid plays an important role in the purification of aluminum and uranium. Hydrofluoric acid is also used to etch glass, engraving patterns, marking scales and characters; the semiconductor industry uses it to remove oxides on the surface of silicon, and it can be used in refineries for the alkylation reaction of isobutane and n-butene Catalyst, hydrofluoric acid is also used in the "pickling" process that removes oxygen-containing impurities from the surface of stainless steel. Hydrofluoric acid is also used in the synthesis of various fluorine-containing organic compounds, such as Teflon (polytetrafluoroethylene) and refrigerants such as Freon. Although hydrofluoric acid has a wide range of uses, special attention should b...
