Description

Technical Field

[0002] In various fields of process technology, solvent bottles are required to contain various solutions, including colorless and flammable, colored and toxic, toxic and corrosive chemical solvents. Traditional processing and cleaning of solvent bottles requires the use of a large amount of cleaning agents and consumes a lot of personnel energy for cleaning operations.

[0003] On the one hand, the traditional method of cleaning solvent bottles is to pour cleaning liquid into the solvent bottle and rinse it multiple times, or to place the solvent bottle in a cleaning liquid tank for soaking and then rinsing. This operation process not only consumes material costs but also has a low time efficiency. On the other hand, the solvent bottle cleaning process requires strict control of particulate matter to ensure the cleanliness of the solvent bottle, but manual operation by personnel cannot effectively ensure the environment and there is a risk of cross-contamination of the solvent bottle. In addition, during the cleaning process of chemical solvent bottles, personnel frequently come into contact with various chemical reagents, which poses many safety hazards.

[0004] For example, Chinese patent document 202310129527.3 discloses a multi-station solvent bottle cleaning device, which relates to the field of solvent bottle processing technology, including: a processing box, with an equipment box installed on the top, and multiple firmness detection mechanisms installed inside the equipment box through a first moving mechanism; a translation frame is installed inside the processing box just below the equipment box, and a cleaning mechanism is installed on one side of the processing box through a first cylinder; a water stain detection mechanism and a cleaning mechanism are both connected to the output end of the translation frame, and the water stain detection mechanism and the cleaning mechanism are alternately moved to the just below the equipment box through the translation frame. The present invention can transport multiple groups of solvent bottles to the processing box through a conveying rack, thereby realizing multi-station cleaning of the solvent bottles, and the processing box is provided with a firmness detection mechanism, a cleaning mechanism, a water stain detection mechanism and a cleaning mechanism on the outside of the corresponding processing station of the conveying rack, and the solvent bottles can be subjected to the processes of firmness detection, cleaning, drying and drying detection in sequence.

[0005] In the above technical solution, although the automatic cleaning and drying of the solvent bottle is realized, the lack of unit switching makes it impossible to realize multi-stage cleaning operations, resulting in incomplete cleaning. In addition, there is a lack of detection function for the residual liquid in the solvent bottle, so it is impossible to determine whether the solvent bottle is thoroughly cleaned without residue, which easily leads to cross contamination when the solvent bottle is reused.
