Description

Technical Field

[0001] The utility model relates to the technical field of threonine production systems, in particular to a manual liquid skimming device for a flat-plate scraper bottom-discharging centrifuge. Background Art

[0002] In the existing threonine production process, the flat scraper bottom discharge centrifuge separates the crystals in the raw liquid crystal material from the mother liquor during operation. However, the mother liquor is in the upper layer of the crystals for a long time during the separation process, resulting in a long dehydration and separation time. The instability of the liquid causes the centrifuge to vibrate violently, causing serious damage to the equipment.

[0003] Usually, a skimming device is added to assist in liquid drainage. When the skimming device is in use, after the material is centrifuged and layered through the centrifuge drum, part of the light liquid in the drum will no longer pass through the filter cake layer and the filter medium, but will be directly led out of the machine through the skimming pipe in the skimming device, ultimately achieving the purpose of shortening the material deliquescence time and reducing the moisture content of the filter cake. Although the skimming device can discharge the light liquid, it usually occurs that the skimming is not thorough or too much filter cake is skimmed. Utility Model Content
