Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, in particular to a novel water-acid filling device. Background Art

[0002] The traditional scale used in aqueous acid filling equipment lacks accurate and intuitive weight measurements. Furthermore, the large diameter (DN25) of the filling pipe and the high filling speed make filling weights prone to significant errors, making it easy to underfill or overfill. Each filling operation requires a staff member to monitor each unit. After the filling weight is reached, the inlet valve must be manually closed. Filling takes approximately one minute, and constant attention must be paid to prevent overfilling or even overflowing. After filling is completed, the valve is closed, which is still some distance from the filling port. Any acid remaining on the inner wall of the pipe after closing can drip around the filling port or onto the filling machine, requiring manual wiping by the operator. If this is not detected, other employees could be unknowingly injured during labeling and handling. After the product is shipped to the buyer, the buyer's staff could also come into contact with the acid dripping from the barrel's outer wall during handling and use, potentially causing injury. A new aqueous acid filling system was needed to address this issue. Utility Model Content
