Description

Technical Field

[0001] The utility model relates to the technical field of vacuum filtration, in particular to a vacuum liquid discharge device capable of cleaning slag. Background Art

[0002] A vacuum filter is a device that uses vacuum negative pressure as a driving force to achieve solid-liquid separation. It can continuously complete operations such as filtering, washing, drying, and filter cloth regeneration. After the material is filtered by the vacuum filter, the filtrate produced needs to be discharged through a vacuum drainage tank. A commonly used vacuum drainage tank is provided with a partition inside the tank body, which divides the tank body into two cavities, an upper chamber, and a lower chamber. By making the upper chamber reach a vacuum, the filtrate is sucked into the upper chamber, and then by making the lower chamber reach a vacuum, the filtrate enters the lower chamber and is discharged from the drainage port, thereby achieving vacuum suction and drainage.
