Description

Technical Field

[0001] The present application relates to the field of paint residue filtering devices, and in particular to a paint residue filtering device for separating paint residues using a centrifuge. Background Art

[0002] The spraying workshop collects paint residues by using a scraper. The scraper separates the paint residues on the surface of the residue pool through a scraper plate. The scraper plate will bring out a large amount of water in the process of scraping and mix it with the paint residue to form a mixture of paint residue and water, which increases the weight of the paint residue and increases the cost of paint residue treatment. In order to reduce the cost of paint residue treatment, the paint residue needs to be filtered.

[0003] The horizontal spiral decanter centrifuge is a device with efficient solid-liquid separation function. The solid-liquid separation of paint residue by the horizontal spiral decanter centrifuge can significantly reduce the weight of the paint residue, thereby reducing the cost of paint residue treatment. However, when the paint residue is discharged from the horizontal spiral decanter centrifuge, part of it will be ejected onto the inner wall of the shell of the horizontal spiral decanter centrifuge. When the paint residue on the inner wall of the shell falls into the discharge pipe, it is easy to accumulate, which leads to poor discharge of the paint residue and reduces the efficiency of paint residue treatment.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the paint residue sprayed on the inner wall of the shell is easy to accumulate in the discharge pipe, thereby reducing the discharge efficiency of the paint residue and further reducing the treatment efficiency of the paint residue.
