Ubungakanani bamasuntswana bubhekisa ekubeni kukho inani elithile lamasuntswana amakhulu okanye amancinci kwimveliso. Amasuntswana amakhulu amasuntswana enobukhulu obungaphezulu kwe-5mm kuyo nayiphi na indlela, kuquka namasuntswana aqhubekekayo. Ukuba isikrini sakho sokungcangcazela simiselwe ukuba sibe nobubanzi be-mesh obuyi-8mm bokukhusela izinto ezinkulu, izixhobo ezinobubanzi obuyi-5~8mm ngokuqinisekileyo ziya kungena kwizixhobo zemveliso ngesikrini sokungcangcazela ngexesha lokusebenza kwesikrini sokungcangcazela.
Amasuntswana amancinci achazwa njengamasuntswana anobukhulu obungaphantsi kwe-2 mm nakweyiphi na indlela, kuquka iitships kunye namasuntswana aphukileyo.
Okulandelayo sihlalutya izizathu zokwakheka kwamasuntswana amakhulu namancinci.
isizathu
Itemplate yobushushu bokufudumeza
Nokuba ubushushu bokufudumeza betemplate buyafana okanye abufani buchaphazela ngokuthe ngqo ukuba izinto ezinyibilikisiweyo zinokudlula kakuhle kumjelo wokwenza itemplate yegranulation. Itemplate esetyenziswa kwesi sixhobo yitemplate yohlobo lwetshaneli eshushu. Ioyile eshushu enobushushu obuphezulu ifudunyezwa ngaphakathi ukugcina i-resin ikwimeko entle yokunyibilika. Imingxunya yedayi isasazwa ngokulinganayo kwitemplate. Kuphela xa isantya sokukhupha umngxuma ngamnye wedayi sihambelana apho amasuntswana anobukhulu obufanayo angasikwa.
Ukuba ulawulo lobushushu alulingani, isantya sokuhamba kwezinto kwezinye iimbobo zokudaya asiyi kulingana. Phantsi kwesenzo se-granulating cutter, amasuntswana angaqhelekanga anobude obahlukeneyo aya kuvela, nto leyo echaphazela kakhulu umgangatho wemveliso. Ngenxa yokuba inkqubo yeoyile eshushu yesi sixhobo ayiloyilo luvaliweyo, ioyile eshushu kulula ukuyikhabhoniza ngexesha lokusebenza. Izinto ezikhabhoni kulula ukuzivimba okanye ukuzincamathela kumjelo wokuhamba xa inkqubo yeoyile eshushu isebenza, nto leyo ebangela ukufudumeza okungalinganiyo. Ngaphezu koko, ngenxa yezizathu zoyilo, umbhobho weoyile eshushu ujikeleziswa kwindawo ephezulu. Ukuba inkqubo yeoyile eshushu ayivalwanga ngokufanelekileyo, umoya uya kungena ngokulula, nto leyo ebangela ukutshintshatshintsha koxinzelelo lwenkqubo kunye nokufudumeza okungalinganiyo kwethempleyithi.
Ukongeza, xa kuveliswa iimveliso ezinesantya esiphantsi sokunyibilika, itemplate isebenza ixesha elide, kwaye isihluzo esineembobo ezinkulu esisetyenziswayo ngokuqinisekileyo siya kuba nenani elincinci le-carbide elingena kwitemplate. Ukuqokelelana kwexesha elide kuya kubangela ukuba umngxuma wokubumba uvalwe ngokulula. Xa i-resin idlula kumngxuma wokubumba, iya kumelana okwahlukileyo kunye nesantya esahlukileyo kumngxuma wokubola kuya kuvelisa amasuntswana amakhulu namancinci.
Isikiti
Ukuguguleka okanye ukwaphuka kwesitshizi kunokubangela amasuntswana amakhulu okanye amancinci. Nokuba uxinzelelo lokutya kwesitshizi luyahambelana na isantya sesitshizi kuchaphazela ngokuthe ngqo ubude bamasuntswana kunye nobomi benkonzo yesitshizi. Uxinzelelo olugqithisileyo lwesitshizi luya kukhokelela kwiingozi zokuphuka kwemela, kwaye uxinzelelo lokutya oluncinci kakhulu luya kukhokelela kwiingozi zokubanjwa kwemela okanye nokubanjwa kwemela, nto leyo echaphazela kakhulu umgangatho wokutsalwa kwepellet.
Umsiki uchaphazeleka ziimeko zezinto kunye nenkqubo, kwaye udlakazwa kakhulu; xa usebenzisa i-extrusion granulator, umthwalo uphakanyiswa kwaye wehliswe ngokukhawuleza kakhulu, nto leyo ebangela utshintsho olukhulu loxinzelelo kwi-cutterhead, kwaye i-cutter kulula ukuyiphula; ngexesha lenkqubo yokutshintsha isikrini se-screen changer, ngenxa yokuba igesi yangaphakathi ayikhutshelwanga kakuhle, nto leyo ebangela ukuba igesi eseleyo kwi-screen changer ikhutshwe kwi-template iye kwigumbi lamanzi, nto leyo ebangela utshintsho olukhulu kuxinzelelo lwe-cutter. Ezi zizathu ziya kubangela ukuba imeko yokusebenza ye-pelletizer yonakale, kwaye i-pelletizing ayizukufana ngokwaneleyo, nto leyo ebangela ukuba kubekho iinkozo ezincinci ezinkulu. Phakathi kwazo, xa isantya se-mese siphezulu kunesantya sokukhupha izinto, kuya kubakho ukwanda kwamasuntswana amancinci. Ngokwahlukileyo koko, xa isantya se-mese siphantsi kunesantya sokukhupha izinto, kuya kubakho ukwanda kwamasuntswana amakhulu. Okwangoku, isantya sokusika sale sixhobo silawulwa kwi-300 ~ 600r/min. Ngalo lonke ixesha umthwalo unyuka okanye wehla ngetoni enye, lungisa phezulu okanye wehle nge-5r/min.
Ubushushu bamanzi okupholisa abunangqiqo
Kwinkqubo yokuqalisa iyunithi ye-granulation, enye yezona zinto zibalulekileyo ezimisela impumelelo yeyunithi yokuqalisa kukudibanisa ngaxeshanye "amanzi", "imela" kunye "nezinto". Oko kukuthi, iinkqubo ezintathu zamanzi okupholisa angena kwigumbi lamanzi, ukujikeleza kwe-pelletizer cutterhead, kunye nokukhupha itemplate kufuneka zenziwe ngaxeshanye ukuqinisekisa ukuqalisa ngempumelelo. Ukubekwa kobushushu bamanzi okupholisa yenye yezona zinto zibalulekileyo.
Emva kokuba amanzi okupholisa engene kwigumbi lamanzi, itemplate ipholiswa ngokukhawuleza, ingakumbi isiqingatha esisezantsi setemplate sesokuqala ukuchukumisa amanzi okupholisa. Ukuba ubushushu obusetwe ngamanzi okupholisa abunangqiqo, umngxuma wokufa kwisiqingatha esisezantsi setemplate unokuvalwa kwindawo enkulu. Umngxuma wokufa ovalekileyo kuya kuba nzima ukuwuvula yipolymer kwimveliso elandelayo, nto leyo ebangela ukuba umngxuma wokukhupha wetemplate uphume. Isantya asilingani, isiphumo sokusika asiqhelekanga, kwaye "iinkozo ezinkulu nezincinci" zenziwa. Ubushushu bamanzi okupholisa obungenangqiqo buya kunciphisa ubomi benkonzo yomsiki.
Ezinye izizathu
Xa kuveliswa iimveliso ze-polypropylene ezine-MFR eyahlukileyo kunye nomxholo webhulabha, kuyimfuneko ukulungisa iiparameter zenkqubo yokusebenza ye-pelletizer. Ukuba iiparameter azimiselwanga ngokufanelekileyo, isantya se-pelletizer kunye nomsantsa phakathi kwe-cutter kunye ne-template aziyi kufaneleka, nto leyo eya kukhokelela ekungalinganini. Pelletizing, nto leyo ebangela iinkozo ezinkulu nezincinci.
Phuculo
Ulawulo loxinzelelo lwemela, ulawulo lobushushu bamanzi apholisayo
Ubungakanani boxinzelelo lwemela bumisela ngokuthe ngqo umgangatho wesimo sengqolowa. Uxinzelelo olugqithisileyo lwemela luya kubangela ukuba imela erhabaxa ibe kufutshane netemplate, nto leyo eya kubangela ukuguguleka kwesixhobo sokusika kunye neengozi zokuphuka kwemela. Uxinzelelo oluncinci kakhulu lwemela luya kubangela ukuba imela ibambeke. , imela yomgca. Ke ngoko, ilawulwa ngokungqongqo ukulawula uxinzelelo lwemela kwi-(0.2±0.05) MPa.
Ukuba ubushushu bamanzi okupholisa buphantsi kakhulu, imingxunya ye-die yetemplate iya kuvalwa, ngelixa ukuba ubushushu buphezulu kakhulu, kuya kubangela ukuqhekeka kwamathambo kunye nokuqhekeka okuqhubekayo. Ke ngoko, ukulawula ngokungqongqo ubushushu bamanzi okupholisa kunye nokuwagcina kwi-50~65℃ kunokunciphisa ngempumelelo ukwakheka kwamasuntswana amakhulu namancinci.
Tshintsha ngexesha elifanelekileyo isixhobo sokusika i-granulation kunye nexabiso le-pH yamanzi okupholisa
I-asidi kunye ne-alkalinity yamanzi okupholisa ziya kuba nefuthe elithile lokubola ngasemva kwesitshizi. Ekubeni amanzi okupholisa asetyenziswa kwesi sixhobo evela emanzini angenatyuwa, i-pH=6 ine-asidi. Ke ngoko, ukuze sandise ubomi benkonzo yesitshizi kwaye sithintele ukuba isitshizi singaphuki ngequbuliso ngexesha lokusetyenziswa ixesha elide, kufuneka siqinise ukujonga isitshizi kwaye sitshintshe i-blade ngexesha. I-alkali ebuthathaka efanelekileyo inokongezwa ukutshintsha i-pH yamanzi okupholisa ukuba ingathathi cala, ukunciphisa amathuba okubola.
Ukuqinisa ukubekwa esweni nolawulo lwemihla ngemihla
Ukuze kulawulwe umgangatho wokubonakala kwee-particles, ukuhlolwa kwesimo se-particles ngexesha lokuthathwa kweesampuli kuyaqiniswa. Ngexesha lokuthathwa kwee-granulation sampling, umqhubi kufuneka ajonge ngononophelo ukubonakala kwee-granules. Ukuba kukho ii-granules ezinkulu okanye ezincinci, yazisa ngokukhawuleza abasebenzi benkqubo kunye nezixhobo ukuze bajonge kwaye bajongane nomsiki. Kwangaxeshanye, nxibelelana nabasebenzi bovavanyo ukuze bahlole ubungakanani bee-particles. Kubalulekile ukuqinisa umsebenzi wokuhlola, kwaye xa kufunyaniswe ukuba kukho ii-particles ezinkulu nezincinci, iiparameters zenkqubo kufuneka zilungiswe ngexesha kwaye izinga lokuvula kufuneka libalwe.
(isantya semveliso × inani lamasuntswana × 1000) ÷ (inani leeblayidi × isantya semela × 60) = inani lemingxuma egudileyo kwifomyula: isantya semveliso se-kg / h; inani lamasuntswana kwi-g; isantya se-pelletizer r / min (inani lemingxuma ÷ inani lemingxuma kwisikhunta) × 100% = isantya semingxuma evulekileyo.
