Uthini umahluko phakathi kwe-ribbon blender kunye ne-V-blender?

1. Umgaqo wokusebenza kunye neempawu zesakhiwo

Iumxube weribhoniithatha isakhiwo se-cylinder esithe tye kunye neribhoni evuselela i-paddle ngaphakathi. Xa usebenza, i-paddle evuselelayo ijikeleza phantsi komqhubi wesixhobo sokuqhuba, iqhubela izinto eziphathekayo ukuba zihambe nge-axially kunye ne-radially, zenze i-trajectory ye-motion eyinkimbinkimbi. Esi sakhiwo sesakhiwo senza ukuba izinto eziphathekayo zixhomekeke kwimiphumo emithathu yokuxuba i-shear, i-convection kunye ne-diffusion ngexesha lenkqubo yokuxuba, eyona nto ifanelekileyo ngokuxutywa kwezinto ezibonakalayo.

Umxube wohlobo lwe-V wamkela uyilo olukhethekileyo lwesikhongozeli esingu-V, kwaye isikhongozeli sijikeleza i-axis ye-symmetry. Ngethuba lenkqubo yokujikeleza, izinto eziphathekayo zihlukana ngokuqhubekayo kwaye zihlanganiswe phantsi kwesenzo sobunzima ukuze zenze i-convection mixing. Le ndlela yokuxuba ixhomekeke kakhulu ekuhambeni ngokukhululekileyo kwezinto eziphathekayo, kwaye ukudibanisa ukunyaniseka kuncinci, kodwa kunokuphepha ngokufanelekileyo ukudibanisa izinto eziphathekayo.

2. Uthelekiso lweempawu zokusebenza

Ukudibanisa ukufanayo kuyisalathisi esibalulekileyo sokulinganisa ukusebenza kwezixhobo zokuxuba. Ngeempawu zayo zokuxuba okunyanzeliswayo, umxube weribhoni unokufezekisa ukufana okuphezulu kokuxuba, ngokuqhelekileyo ukufikelela ngaphezu kwe-95%. Umxube wohlobo lwe-V uxhomekeke kumxube womxhuzulane, kwaye ukufana ngokubanzi kujikeleze i-90%, kodwa kunempembelelo engcono yokukhusela kwizinto ezibuthathaka.

Ngokumalunga nokusebenza kakuhle kokuxuba, i-ribbon mixer idla ngokuthatha imizuzu eyi-10 ukuya kwengama-30 ukugqiba ukudibanisa ibhetshi yezinto, ngelixa i-V-type mixer ithatha imizuzu engama-30-60. Lo mahluko ubangelwa ikakhulu kwiindlela ezahlukeneyo zokuxutywa kwezi zimbini. Indlela yokuxuba ngokunyanzeliswa kwe-ribbon mixer inokufezekisa ukusabalalisa okufanayo kwezinto ngokukhawuleza.

Ngokumalunga nokucoca kunye nokugcinwa, i-V-type mixer ilungele ukucoca ngenxa yesakhiwo sayo esilula. Isakhiwo sangaphakathi somxube we-ribbon sinzima kwaye kunzima ukucoca, kodwa izixhobo zanamhlanje zixhotyiswe kakhulu ngenkqubo yokucoca i-CIP, enokusombulula ngempumelelo le ngxaki.

3. Umda wesicelo kunye neengcebiso zokukhetha

I-Screw-belt mixers isetyenziswa ngokubanzi kwiikhemikhali, ukutya, amayeza kunye namanye amashishini, ngakumbi ukuxuba izinto eziphezulu ze-viscosity, ezifana ne-slurries kunye ne-pastes. Abaxube bohlobo lwe-V bafaneleke ngakumbi ukuxuba izinto ezinobumanzi obuhle, obufana nomgubo kunye neengqungquthela, kwaye zisetyenziswa ngokubanzi kumashishini amayeza kunye nokutya.

Xa ukhetha izixhobo, kuyimfuneko ukugxila kwiimpawu eziphathekayo, umlinganiselo wemveliso kunye neemfuno zenkqubo. Kwizinto eziphathekayo ezine-viscosity ephezulu kunye neemfuno eziphezulu zokufana, kuyacetyiswa ukuba ukhethe i-screw-belt mixer; kwizinto ezibuthathaka kunye nezilulwelo, i-V-type mixer lukhetho olungcono. Kwangaxeshanye, isikali semveliso kufuneka siqwalaselwe. Imveliso enkulu eqhubekayo ifaneleke ngakumbi ukusetyenziswa kwe-screw-belt mixers, ngelixa i-batch encinci ye-multi-variety production ifanelekile ngakumbi kwi-V-type mixers.

Ngokuqhubela phambili kwetekhnoloji yoshishino, zombini iindidi zezixhobo zokuxuba ziphuhlisa ukuya kubukrelekrele kunye nokusebenza kakuhle. Kwixesha elizayo, ukukhethwa kwezixhobo kuya kuhlawula ingqalelo ngakumbi ekusebenzeni kakuhle kwamandla kunye nolawulo olukrelekrele ukuhlangabezana neemfuno ezisulungekileyo zemveliso yanamhlanje. Xa ukhetha izixhobo zokuxuba, amashishini kufuneka aqwalasele ngokupheleleyo iimpawu zabo zokuvelisa kunye nezikhokelo zophuhliso lwexesha elizayo kwaye akhethe ezona zixhobo ezifanelekileyo zokuxuba.
