Yini Isakhiwo Se-Silo Yokugcina Eyisilinda Imithwalo Nokwakhiwa
I-silo yokugcina eyisilinda iyisilinda sensimbi emile esetshenziselwa izinto ezomileyo eziningi — okusanhlamvu, usimende, impuphu, ama-pellets noma izingcezu — ehlinzekwa ngamaphaneli ahlanganisiwe enziwe efektri noma ngegobolondo lamapuleti ashiselwe. Umsebenzi wesakhiwo uyisilinda ngaphansi komthwalo womoya, iqhwa nokuzamazama komhlaba emi phezu kwesisekelo esiyindandatho noma esicaba, kodwa ubunjiniyela obunquma impilo yesevisi ukujula kobukhulu bodonga, ukuma kwaphansi, ukudonsa kwamanzi ophahleni nokuvikelwa kokugqwala kwangaphakathi. I-silo yensimbi ehlanganiswe nengilazi ihlanganisa ungqimba lwe-enamel ku-820–930 °C futhi olungu-0.25–0.45 mm ubukhulu, ihlolwe nge-spark ku-1500 V DC futhi inikeza ingaphakathi elingasebenziyo le-pH 1–14 ukuze liphile iminyaka engaphezu kwengama-30.
Ungunjiniyela owayehlile nje amathangi oketshezi uhlangabezana ne-silo eyisilinda njengomkhakha ohlukile: umthwalo awusona ikhanda le-hydrostatic kodwa ingcindezi evela ezintweni eziqinile ezigciniwe, udonga lukhuluphala phansi kunaphezulu, futhi uphahla kufanele lukhiphe kokubili iqhwa namanzi kuyilapho lugcina ingaphakathi lomile. Ama-silo ayisilinda ayisitsha esivamile sezinto eziqinile ezomile, futhi ukuma kwawo kulula ngokwanele kangangokuthi iningi lenani lisezincwadini — ukuma kodonga, isisekelo sendandatho, indawo yokuphuma, umsele wophahla kanye namajoyinti. Le ndatshana ihlanganisa ukuthi siyini isitsha, ukuthi sithwalwa kanjani, nokuthi izindlela eziboshiwe nezishiseliwe zihluka kanjani ekusebenzeni.
Uhlelo lwesakhiwo kanye nemithwalo elithwalayo
I-silo eyisilinda iyigobolondo elingaphansi kwezimo ezine zomthwalo ezingazimeli zodwa. Okokuqala yisimo sokugcwalisa: impahla egciniwe icinezela eceleni odongeni futhi ngokuqondile phansi, nengcindezi yeceleni ekhuphuka cishe ngokujula, yingakho izindonga ze-silo zikhudlukazi ezansi futhi zilula phezulu. Okwesibili yisimo esingenalutho, lapho umoya uwumthwalo olawulayo futhi isakhiwo silula futhi side, ngakho ukwakheka kwe-anchor kufanele kumelane nokuphakanyiswa kanye nesisindo esigcwalisiwe. Okwesithathu iqhwa neqwa eluphahleni, okuthi ku-silo eyisilinda kusho amapuleti ophahla, ama-rafter noma igobolondo le-dome kanye nomsele. Okwesine ukuzamazama komhlaba, okuthi ku-silo ende kube umbuzo we-base-shear nokugingqika futhi kowesilinda omude kube umbuzo wokuqhekeka kodonga. Lapho kunikezwa uphahla lwe-dome ye-aluminium ye-geodesic, i-dome ibhekiselwa ku-AWWA D108 kanye ne-API 650 futhi izimo zomthwalo womoya neqhwa zithathwa ku-ADM 2015 noma i-ASCE 7-10, okuyindlela ehlanzekile yokugcina umthwalo wophahla uhlukile ekuhlolweni kwegobolondo.
Ukwakhiwa okuboshiwe kuqhathaniswa nokushiseliwe
Umzila wokulethwa ushintsha uhlelo lokumiswa, ukuhlolwa ngokuhlanganyela kanye nendlela yokwandiswa kwesikhathi esizayo. I-silo eyisilinda eboshwe ngamabhawodi yakhiwa ngamaphaneli enziwe efektriji acishe abe ngu-1.2 m ububanzi, anamajoyinti aneflange, ama-gasket e-EPDM kanye namabhawodi ezinga le-8.8, ilethwa njengephakethe eliyisicaba futhi ihlanganiswe endaweni; umsebenzi wasensimini ukubopha ngamabhawodi ngokulawula i-torque, futhi igobolondo eliqediwe lingaphakanyiswa ngamakhosi engeziwe kamuva noma landiswe ngamaphaneli engeziwe. I-silo edidiyelwe yakhiwa ngephepha eligoqiwe elinemithungo eqhubekayo ehlolwa ngendlela okuvunyelwene ngayo esivumelwaneni, okunikeza umgoqo oqinile oqhubekayo futhi ngokuvamile kuyindlela engabizi kakhulu kumabubanzi amancane; ububi bayo ukuthi ayikwazi ukwandiswa futhi noma yikuphi ukulungiswa kuwukudidiyela kwensimini okunesilinganiso sokuhlolwa esifanayo. Zombili izakhiwo ezingaphansi komkhathi ezimile odongeni lweringi lukakhonkolo noma ku-slab eyisicaba enezibophezelo, futhi umehluko wokuzinza kulo lonke isisekelo kufanele ulawulwe ngoba igobolondo le-silo lizwela ukunyakaza okuhlukile esigabeni saphansi.
Isimo sodonga, ijiyometri yaphansi kanye nokuphuma
I-silo ishibhile uma udonga lulandela umthwalo, futhi phansi kulandela impahla. Ukujiya kodonga kuyenyuka ngezigaba: ipuleti elisindayo ezigabeni eziphansi lapho ingcindezi yento eqinile egciniwe iphezulu kakhulu, ipuleti elilula phezulu. Phansi kungaba yiflori eliyisicaba, isisekelo esiyikhoni esinomthambeka odlula i-engeli yokugeleza kwempahla, noma isisekelo esiyifaneli njengesixazululo esingajulile; isicaba sithanda indawo enkulu yepulani kanye nezindleko eziphansi zensimbi, ikhoni ithanda ukukhishwa okuphelele kanye nomgudu owodwa olawulwayo, kanti ifaneli ithanda isilo eside lapho ikhoni ephelele ingeke ingene. Ububanzi bomgudu wokuphuma kufanele bulinganiswe kusukela ekuminyaneni kwengqimba kanye nezinga lokukhishwa elidingekayo, futhi imishini yokukhipha — isikrufu, i-rotary airlock, isilayidi samandla adonsela phansi noma i-drag chain — iklanywa kanye nesilo, ngoba umgudu wokuphuma omncane kakhulu uguqula impahla yokugcina ibe yisithiyo.
Ukuvikelwa kokugqwala kanye nendawo yangaphakathi
I-dry bulk ithambile kunesevisi yoketshezi, yingakho i-galvanising isaxhaphakile lapha, kodwa i-bulk emanzi noma ene-asidi ayinjalo. I-hot-dip galvanising ngokwe-GB/T 13912-2020 iyisixazululo esingabizi kakhulu se-dry, inert bulk — okusanhlamvu, usimende owomile, ama-pellets epulasitiki — lapho ingaphakathi lihlala lomile; inikeza ukuvikelwa kwe-sacrificial kodwa ayinandawo ekusebenzeni okune-asidi enamandla noma i-alkaline enamandla noma ekuxhumaneni nokudla nokuphakelayo. Kwi-bulk emanzi, ene-asidi noma i-alkaline, nakuwo wonke umsebenzi lapho ingaphakathi lihlanjululwa phakathi kwemikhankaso, i-silo ye-glass-fused-to-steel ithwala ungqimba lwe-enamel oluhlanganiswe ku-820–930 °C, olungu-0.25–0.45 mm ubukhulu, olulinganiselwe ngaphezu kwe-3,450 N/cm², oluhlolwe nge-spark ku-1500 V DC, olubushelelezi ku-Ra engaphansi kwe-0.8 µm futhi olubekezelela i-pH 1–14, okunikeza ingaphakathi elingasebenzi elilinganiswa ngamashumi eminyaka kunemijikelezo ye-coating. Noma yiluphi uhlelo olukhethiwe, uphahla kanye nomsele kuyingxenye yendaba yokugqwala: uphahla oluvuzayo noma umsele ovimbekile kubeka amanzi esigabeni esiphezulu, okuyilapho ukhumba lwe-silo ngokuvamile luqala khona ukwehluleka.
