Description

Technical Field

[0001] The present application relates to the technical field of centrifuges, and in particular to a centrifuge drum and filter bag mechanism. Background Art

[0002] Flat plate sealed centrifuges are suitable for solid-liquid separation of suspensions with high solid bulk, moderate particle size, low compressibility, requiring washing, and low liquid viscosity. They are suitable not only for separating small batches of diverse materials, but also for large-scale production. They are widely used in other industrial fields such as medicine, chemicals, mining, light industry, food, national defense, and new energy.

[0003] In the prior art, this type of centrifuge is a type of filtering centrifuge. The centrifuge's drum consists of a basket bottom, a cylinder, a liquid baffle and other major components. A filter bag is installed in the drum. The centrifugal force generated by the high-speed operation of the drum is used to separate the filtrate injected into the drum through the filter bag lined with the drum, leaving the filter residue in the drum. The filtrate flows to a collector through the liquid outlet. After separation, the power is cut off, the drum is stopped by a control device, all locking devices are opened, the cover is opened, and the material is discharged. However, when centrifuging materials with an ultra-low solid-liquid ratio, due to the lack of material, it is difficult to compact the filter bag, resulting in the filter bag and the inside of the centrifuge drum not fitting together. Friction occurs during the centrifugation process, causing the filter bag to wear, causing the material to pass through the damaged area. This results in unsatisfactory solid-liquid separation and dehydration washing, requiring rework. The operation is complicated and inefficient, making it unsuitable for industrial production and unable to meet the requirements of actual production. Moreover, the filter bag needs to be replaced, which increases production costs. Utility Model Content
