BIN FOR STORAGE OF PREMIX, METHOD OF PREMIX STORAGE AND METHOD OF PUMPING OVER OF HOT VISCOUS MIX Russian patent published in 1999 - IPC

FIELD: equipment and methods for premix storage and pumping over of hot viscous mix. SUBSTANCE: bin for storage of hot viscous pasty mix containing cellulose dispersed in solution of tertiary amine oxide and water has vertical reservoir having central shaft rotating round the vertical axis and provided with agitating members and heating device for heating reservoir side walls. The invention also concerns the method of storage of mix based on cellulose and the method of transportation of mix to other place for its treatment. During storage, mix is continuously agitated in vertical reservoir, and its temperature is maintained elevated. From bin, hot viscous pasty mix is pumped over to other section of treatment. EFFECT: provision of storage of viscous premix based on cellulose dispersed in solvent during the period of time from premix preparation to its transportation to the other section of its chemical treatment such as section of preparation of spinning solution. 13 cl, 9 dwg
