Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of overflow liquid recovery devices, in particular to an overflow liquid recovery device in a polyether macromonomer liquid slicing process. Background Art
[0002] After the liquid material of the polyether macromonomer is pumped to the slicer trough, the liquid material is condensed into a solid using chilled water, scraped off by the front blade of the slicer roller and transported to the product silo to be packaged on the downstream packaging line. During the entire production process, the slice thickness, the adjustment of chilled water, the roller speed, and the feeding depth all need to be adjusted in combination with the actual slicing effect during the equipment operation process, to ensure that the product is completely condensed and free of sticky materials, and to ensure the basic production capacity of the production line. The liquid level of the slicer trough plays a key role. During production operation, the liquid level of the trough is often too high and overflows due to improper operation of the operator and untimely inspection. In severe cases, the liquid material flows through the front blade of the slicer to the silo and the ground around the slicer, causing abnormal shutdown and a large amount of material loss. The existing technology can only be observed by the operator's inspection and timely shutdown when overflow occurs. However, there is still a situation where material overflow occurs due to untimely inspection. Utility Model Content
