Lapho ukhiqiza izinqwaba zamapayipi kakhonkolo wamandla aphezulu (izinqwaba zamapayipi e-PHC okwesikhashana), Inqubo yokukhiqiza "yokwelapha okwesibili", ehlanganisa ukuphulukiswa kwesitimu somoya kanye nokuphulukiswa kwe-autoclave, ngokuvamile kuyamukelwa.I-silica sand powder (noma isihlabathi esihle esiphansi) isetshenziswa ekukhiqizeni izinqwaba zamapayipi e-PHC ngokusebenzisa ngokunenzuzo izici zokusabela kwe-hydrothermal synthesis ngesikhathi sokuphulukiswa kwe-autoclave Lobu buchwepheshe abukwazi ukunciphisa ukusetshenziswa kukasimende kuphela, kodwa futhi bulondoloze amandla futhi bunciphise ukusetshenziswa.Ngesikhathi esifanayo, ingakwazi futhi ukusebenzisa kahle izinsiza zemfucumfucu ye-quartz eshiywe emayini, enezinzuzo ezinhle zobuchwepheshe nezomnotho.Ngakho-ke, yiziphi izinto ezisetshenziswayo ukukhiqiza isihlabathi se-silica esicolekile senqwaba yamapayipi?Njengomphakeli ochwepheshe weisihlabathi se-silicaumshini wokugaya umshini, HCMilling(Guilin Hongcheng) sikaIsihlabathi se-silika se-HLMmpo roller millisetshenziswe kabanzi ekukhiqizeni isihlabathi se-silica esicolekile senqwaba yamapayipi, esizochazwa ngezansi.

Ngokophenyo, i-Sunwood isebenzise impushana yesihlabathi se-silica ekukhiqizeni izinqwaba zamapayipi e-PHC isikhathi eside, kodwa alikho izinga lomkhiqizo wempushana yesihlabathi se-silica.Ukuze kuqinisekiswe ikhwalithi yenqwaba yamapayipi kakhonkolo acindezelwe, akhuthaze kangcono ukuthuthukiswa kwemboni yenqwaba yamapayipi, akhuthaze ukusetshenziswa okubanzi kwempushana yesihlabathi se-silica, aqinisekise ikhwalithi yempushana yesihlabathi se-silica, futhi amise imakethe yesihlabathi se-silica powder, ngokoMqulu No. 7 weKhomishini Yentuthuko Nezinguquko YaseChina ngo-2005, Izinga lemboni yezinto zokwakha JC/T 950-2005 Silica Sand Powder for Prestressed High-strength High-strength Concrete Pipe Piles, eyabhalwa yiCivil Engineering Research Institute yaseJiaxing University. yeSuzhou Concrete and Cement Products Research Institute, yakhululwa ngo-February 14, 2005 futhi yaqala ukusebenza ngo-July 1, 2005.

Ngakho-ke, yiziphi izinto ezingasetshenziswa ukuze kukhiqizwe isihlabathi se-silica esicolekile senqwaba yamapayipi ukuze kuhlangatshezwane nezidingo zekhwalithi zesihlabathi se-silica esicolekile senqwaba yamapayipi?Isihlabathi se-silica iyiminerali ye-silicate eqinile, engagugi futhi ezinzile kumakhemikhali ene-SiO: njengokwakheka kwamaminerali okuyinhloko nosayizi wezinhlayiyana ongu-0.020~3.350mm.Umbala wayo umhlophe omhlophe, ophuzi okhanyayo, onsundu kanye nompunga, ubulukhuni 7, i-brittleness ngaphandle kwe-cleavage, ukuphuka okufana negobolondo, i-grease luster, ukuminyana kwesihlobo 2.65.Ayincibiliki ku-asidi, incibilika kancane kusisombululo se-KOH, iphuzu elincibilikayo 1750C.Ngokwezici ezingokomzimba zesihlabathi se-silica kanye nezidingo zekhwalithi zemikhiqizo yesihlabathi ye-silica emihle yenqwaba yamapayipi.Kucatshangwa ukuthi i-roller, isihlabathi se-silicampo roller mill kanye nebhola lokugaya le-silica sand lingahlangabezana nezidingo zenqubo yokugaya isihlabathi se-silica.Uma umthamo wokucubungula isihlabathi se-silica ungu-5-10t/h, i-roller njenge-silica sand grinding mill inomthamo omkhulu, kodwa ukutshalwa kwezimali kwesistimu kuphezulu.Ngemuva kokuphulwa kwengcindezi yesibili, usayizi womkhiqizo unzima ukuhlangabezana nezidingo, futhi intengo iphezulu.Ukuntuleka kwedatha yokuhlola edingekayo.Kunzima ukuhlangabezana nezidingo;Umshini wokugaya ibhola kulula ukuwugqilaza, usayizi wezinhlayiyana kunzima ukulawula, ukusetshenziswa kwamandla kukhulu, umthamo wokukhiqiza uphansi, ukugeleza kwenqubo kuyinkimbinkimbi, futhi imishini ihlanganisa indawo enkulu.Nakuba intengo yokutshalwa kwezimali iphansi, ayifanele ukukhiqizwa okukhulu kwesihlabathi se-silica esicolekile senqwaba yamapayipi.Ngakho-ke,Isihlabathi se-silika se-HLMmpo roller mill ekugcineni yakhethwa njengempahla yokukhiqiza yesihlabathi se-silica esigaywe kahle senqwaba yamapayipi ngemva kokukhethwa okuyisibopho kwamakhasimende enqwaba yamapayipi.Njengobaisihlabathi se-silicaumshini wokugaya, isihlabathi se-silicampo roller mill inomthamo omkhulu, uhlelo olulula, ukusebenza okuthembekile, ukusebenza okulula, ukuhlanzeka komkhiqizo olawulekayo kanye nokusetshenziswa kwamandla okuphansi.Umgomo wayo wokusebenza kanye nezici zokusebenza zimi kanje:

① Umgomo wokusebenza: iisihlabathi se-siliconmpoukugayaisigayo I-motor ishayela i-disc yokugaya ukuze ijikelezise ngesinciphisi esime mpo, futhi izinto ezingavuthiwe eziqinile zingena phakathi nendawo yediski yokugaya ngomshini wokuphakelayo wokukhiya umoya ukusuka endaweni yokuphakela, bese ziphonswa emaphethelweni e-disc yokugaya ngaphansi kwesenzo inkambu ye-centrifugal force futhi ichotshozwe ukugoqa okuphindaphindiwe kwe-roller yokugaya.Izinto ezichotshoziwe zichichima kusukela onqenqemeni lwepuleti lokugaya, futhi izinto eziyimpushana ezikuyo zithwalwa ukugeleza komoya okuphezulu kwesivinini esikhuphuka sisuka engxenyeni engezansi yomshini, kanye nokukhuphuka komoya kanye nokokusebenza okuyimpuphu kudlula emshinini.Engxenyeni engenhla ye-powder concentrator, ngaphansi kwesenzo se-rotor ejikelezayo ngokushesha, impushana engamahhadla iyahlukaniswa futhi yehliselwe phakathi nendawo yepuleti lokugaya ukuze kugaywe kabusha, futhi impushana ecolekile igaywa kusukela engxenyeni engenhla ye-silica. umshini wokugaya isihlabathi ngokugeleza komoya, futhi uqoqwe kudivayisi yokuqoqa uthuli, okuwumkhiqizo.Izinto eziyisihluthulelo ezingathwalwanga wukugeleza komoya zizochichima ipuleti lokugaya futhi zibuyele endaweni yokuphakelayo yesigayo ngekheshi lebhakede lokujikeleza elingaphandle, bese lingena emshinini wokugaywa ukuze ligaywe kabusha kanye nezinto zokusetshenziswa ezisanda kuphakelwa.

② Izici zokusebenza:

1. Ihlanganisa ukugaya, ukomisa, ukugreda nokudlulisa imisebenzi.Kulula ukusebenza nokulungisa, ngezinga eliphezulu lokuzenzekelayo kanye nomthamo omkhulu wokucubungula womshini owodwa.

2. Ubuhle bemikhiqizo egayiwe bungalungiswa, futhi ukukhetha kahle kwempushana kuphezulu.

3. Ukuguga okuphansi, ukusetshenziswa kwensimbi okuphansi, izinto eziphakeme ezikwazi ukumelana nokugqokwa kwe-disc lining kanye ne-roll surface, impilo ende yesevisi.

4. Ukusebenza okuthembekile nokugcinwa okulula.I-roller yokugaya ingacinywa emzimbeni womshini ngesikhathi sokulungiswa.

5. Ukudlidliza okuphansi, umsindo ophansi, akukho uthuli ngesikhathi sokusebenza kwengcindezi engalungile.

Inqubo yokukhiqiza isihlabathi se-silica esicolekile senqwaba yamapayipi yamukela uhlelo lokugaya okuqondile kwesihlabathi se-silica: inquboisihlabathi se-silicaumshini wokugaya umshini uqala ekwamukeleni nasekugcineni kuye ekuthutheni isihlabathi se-silica esiqediwe, okuhlanganisa ukwamukela nokugcinwa kwesihlabathi se-silica, ukugcinwa kwekheshi lebhakede, ukugaya isihlabathi se-silica ngokugaya okuqondile, ukuqoqwa kothuli lwezikhwama, nokuthuthwa ngaphandle kwesihlabathi se-silica esiqediwe.

① Ukwamukela nokugcinwa kwesihlabathi se-silica: isihlabathi se-silica sithuthwa ku-hopper eyamukelayo ngeloli noma esitokisini kuqala bese kuba yi-hopper eyamukelayo ngeforklift.

② Indawo yokugcina impahla ye-lifti yebhakede: impahla eluhlaza ixhunywe ne-lifti yebhakede ukuze iphakamise isihlabathi se-silica endaweni yokugcina impahla eluhlaza.

③ Ukugaya: i-silica sand raw material bin ixhunywe ne-silica sand vertical roller mill ngokusebenzisa i-flange, futhi izinto zokusetshenziswa zifakwa ku-silica sand vertical roller mill kusukela ekungeneni kokuphakelayo.isihlabathi se-silicampoukugayaisigayoyokugaya.

④ Ukuqoqwa kothuli lwezikhwama: kucatshangelwa izidingo zokuvikela imvelo, idivayisi yokuqoqa uthuli lwezikhwama isethwe ekugcineni komshini wokugaya.

⑤ Ukuthuthwa kwangaphandle kwesihlabathi se-silica esiqediwe: Isihlabathi se-silica esifanelekayo ngemva kokugaya ngebhola singena ebhandeni lezokuthutha langaphandle nge-chute ekugcineni kokukhipha, futhi sithuthelwa emgqonyeni wezinto ezibonakalayo ekamelweni lokuhlanganisa, noma sihlanganyele ngokuqondile ekuhlanganiseni.

I-HCMilling(Guilin Hongcheng) ingumkhiqizi weisihlabathi se-silicampo roller mill.Eyethu isihlabathi se-silicampo roller millifakwe ekukhiqizweni kumaphrojekthi ambalwa okukhiqiza isihlabathi se-silica sokugaya izinqwaba zamapayipi, futhi iqashelwa ngokujulile futhi ithandwa ngamakhasimende.Uma ufuna ukwazi okwengeziwe mayelana nokumiswa kwemishini kanye nokukhiqizwa kanye nokusebenza kwesihlabathi se-silica esicolekile senqwaba yamapayipi, sicela uthinte i-HCM ngemininingwane.
