Analysis On Structure Design And Key Technology Of New Multifunctional Separator

Multi-function separator is comprehensive mechanical equipment inblowing-carding unit generated in the development course of new-type textile rawmaterials, high-end textile variety and multiple textile technology. At present, thecurrent several kinds of multi-function separation equipments still exist the specifieddisparity on the structure, function and production rate compared with foreignproducts. Developed a kind of advanced technology, reasonable structure, completefunction and strong practicability of new multifunctional separation equipment, is theenterprise met the requirements of market development, improved product marketshare, one of the most important aspects of the company’s core competitiveness.Around the core of the new multi-function separator structure design, usingprinciple solution the basic component factors of existing equipments on the marketare parsed, on the basis of building morphology solving matrix to innovate conceptionand design scheme principle diagram of the new-type multi-function separation; fromthe research and analysis of pneumatic conveying system, the key technology ofinternal transfer in the subject is dissected to complete the structure design ofnew-type multi-function separator key components; from the production test, therelationship between cleaning efficiency and raw cotton opening degree is researchedand analyzed, in addition to the process performance, stable performance andeconomic performance in the process of practical application of the new typemulti-functional separator are assessed and analyzed in detail.Through this topic research, the following conclusions are gotten out:1, The new-type multi-function separator is changed from the inlet to the outlet,the static pressure is changed from positive to negative pressure in the region ofU-type separation assembly. The dynamic pressure inside the separator decreasedgradually first up to lowest in the region of U-type separation assembly, and thenbegan to gradually increase;2, The materials inside multi-function separator can be decomposed into threebasic forms such as linear motion, helical motion and jumping motion.3, The actual operation speed of materials in multi-function separator is closelyrelated to the parameters such as terminal velocity, gas ratio and conveying air capacity of fiber bundles, it is function related to the parameters such as the density.4, The cleaning rate of new-type multi-functional separator is closely related tothe opening degree of the raw cotton, the corresponding relations can be shownapproximately in regression equation with one unknown.Production test is shown that the performance designed new-typemulti-functional separator is superior, the stability is strong, its innovative structuraldesign has won the national patent for utility model. All production technicalindicators of the machine are in the current international advanced level.
