[0002] Currently, buffer tanks are used in the solvent-based (lyocell) cellulose liquor production process, positioned between the evaporator / dissolver and the filter. They are connected to a static mixer in front and a booster pump in the back, serving to balance the pressure of the liquor delivery and act as a buffer.
[0003] However, existing raw material buffer tanks generally use the method of reducing drop height to buffer the raw material, but because they cannot achieve uniform liquid distribution and buffering, the liquid will still generate a large impact force when falling from a height, resulting in fluctuations in the subsequent liquid output.
[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, this utility model was created. It is provided to provide a lyocell cellulose concentrate buffer tank to solve the problem that when existing concentrate buffer tanks are used, they generally use the method of reducing the drop height to buffer the concentrate. However, because they cannot achieve uniform liquid distribution and buffering, the liquid will still generate a large impact force when falling from a height, resulting in fluctuations in the subsequent liquid output.
