Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a centrifuge for chemical production. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquid from solid particles or components in a mixture of liquid and liquid. Centrifuges are mainly used to separate solid particles from liquid in a suspension, or to separate two immiscible liquids of different densities in an emulsion (e.g., separating cream from milk); they can also be used to remove liquid from wet solids.

[0003] After searching, the patent document with the announcement number CN219377515U discloses a centrifuge for chemical production, which relates to the technical field of centrifuges. It includes an outer barrel, an inner barrel and a quick-change rotating device, the inner cavity of the outer barrel is connected to the inner barrel, and the bottom of the inner barrel is connected to the quick-change rotating device. When in use, a suitable inner barrel body is placed in the outer barrel body and sleeved on the inner ring of the semicircular bearing, then the limit groove is inserted outside the driving rod, and then the material is placed in the inner barrel body, the inner barrel cover is tightened, and then the outer barrel cover is tightened, the hydraulic rod is extended to push the pad to insert into the positioning groove to fix the inner barrel body, the motor drives the rotating rod and the driving rod to rotate, and the driving rod drives the limit groove and the inner barrel body to rotate so that the material in the inner barrel body rotates to generate centrifugal force, so that the liquid in the material is discharged from the downpipe through the water filter port, thereby realizing the solid-liquid separation of the material, and quickly completing the replacement and disassembly of the centrifugal barrel, improving the practicality of the device and the efficiency of subsequent cleaning.

[0004] When the above device separates solid and liquid through the water filter holes on the inner barrel body, part of the solid raw materials are easily discharged from the water filter holes and adsorbed on the outer surface of the inner barrel body, causing pollution of the inner barrel body surface, and the applicability is poor. Utility Model Content
