Kwadalwa ngo Ngokwamukisa
Umthamo Wesilo, Ukulinganisa Nokubalwa Kwevolumu: Ububanzi, Ubude Nokugcwaliswa
Umthamo we-silo ulawulwa kuqala yi-bulk density yempahla egciniwe futhi okwesibili nje yi-geometry. Umthamo osebenzisekayo ulingana nomthamo we-cylindrical kanye nomthamo we-hopper, kulungiswe i-angle of repose eguquguqukayo endaweni yokugcwalisa, futhi lowo mthamo kufanele uhlukaniswe nge-bulk density ukuze kutholakale amathani umthengi awathola ngempela. I-diameter nokuphakama kuyashintshana ngokumelene nendawo etholakalayo yokwakha, umthwalo wesisekelo kanye nesidingo sokuzamazama komhlaba, ngakho umthamo othile ungafinyelelwa nge-silo ende emincane noma emfushane ebanzi enezindleko nemithelela yekhodi ehluke kakhulu.
Ukucacisa isilo sokugcina ngokuthi "sidinga amathani angu-2,000" ngaphandle kokunquma ukuminyana kwempahla enkulu kanye nokuma kokugcwalisa kukhiqiza umkhumbi omncane kakhulu ukuhlangabezana nokugeleza noma omkhulu ngokweqile ngokumosha isabelomali. Ukulinganisa okulungile kuguqula umgomo wamathani ube yincazelo evikelekile yobubanzi, ukuphakama kanye nokucaciswa kobukhulu bodonga, futhi yisinyathelo sobunjiniyela esivikela kokubili izindleko ezinkulu kanye nemishini yokuphatha engezansi elinganiswe ngokusuka endaweni yokuphuma yesilo.
Umthamo Wesilo Uchazwa Ukuminyana Kwempahla Enkulu Ngaphambi Kokuma
Isilo esilinganiselwe amathani angu-2,000 empahla eyodwa singabamba ingxenye yalokho kwesisindo sempahla eminyene kakhulu egobolondweni elifanayo. Ukuminyana kwempahla enkulu—isisindo ngevolumu yokugcina—yiyona nto enkulu kakhulu eshintshayo kunoma yikuphi ukubalwa komthamo. Usimende cishe ku-1,400 kg/m³ uthatha indawo encane kakhulu kune-fly ash eduze ku-700 kg/m³, futhi i-mineral concentrate engaphezu kuka-2,000 kg/m³ ihlangana ngisho nakakhulu endaweni efanayo.
Ukulandelana kwedizayini evikelekayo ngakho-ke kungumthamo ohlosiwe → ukuminyana kwesamba → umthamo ogciniwe odingekayo → ijiyometri. Thatha ithani njengento engaguquki bese uxazulula ngokuhlehla:
1. Lungisa ukuminyana kwesamba sedizayini kusukela ocwaningweni lwaselabhorethri noma lomphakeli, hhayi inani lethebula elijwayelekile, futhi qaphela ukuthi ingabe ukuminyana kokuthululwayo, kokugedlwayo noma kokufakwa umoya.
2. Hlukanisa isisindo esihlosiwe ngokuminyana ukuze uthole umthamo ogciniwe omsulwa.
3. Engeza u-10–15% we-freeboard nendawo yokugcina yokusebenza yokugcwala okusheshayo nokuhlukahluka kwempahla.
4. Guqula umthamo omsulwa ube ububanzi nokuphakama usebenzisa ubudlelwano bejiyometri obungezansi.

Ububanzi Nokuphakama Kuyashintshana Ngokwesikhala Sendawo Nokuthwala Kwesisekelo
Umthamo onikeziwe ungafinyelelwa nge-silo ende emincane noma emfushane ebanzi, futhi ukukhetha kushintsha izindleko kusuka ensimbi kuya kwisisekelo. Ububanzi bubeka indawo yonyawo kanye nobubanzi bophahla; ukuphakama kubeka umthwalo we-hoop wodonga kanye nokuphakama okuphelele kwemishini yokugcwalisa nokubuyisela.
Ububanzi obuncane (4–8 m) bugcina uphahla lulula futhi inani lamaphaneli liphansi, kodwa kuphoqa ukuphakama okukhulu ukuze kube nomthamo omkhulu, okwandisa amandla omoya nokuzamazama komhlaba. Ububanzi obukhulu (12–25 m) behlisa ukuphakama, kwenza kube lula ukufinyelela kweloli nesithuthi sokuhambisa izinto, futhi kunciphisa ingcindezi ezindongeni, kodwa kudinga isisekelo esindayo sendandatho kanye nesakhiwo sophahla olubanzi olukhulu. Umngcele wendawo, ukufinyelela kukakheshi, kanye nendawo yokuzamazama komhlaba yendawo ngokuvamile kubeka umkhawulo oprakthikali kububanzi, kuyilapho amathani adingekayo kanye nendawo etholakalayo yokuphakama kubeka umkhawulo waphansi ekuphakameni.
I-Angle Yokugcwalisa Ne-Cone Geometry Yehlukanisa Umthamo Osebenzisekayo Nowengqikithi
Ubuso obuphezulu obuyisicaba noma obuyindilinga obushiywe umfudlana wokugcwalisa buphelelwa umthamo ngenxa ye-engeli eguquguqukayo yokuphumula, ngakho umthamo wangaphandle wegobolondo awusoze waba umthamo olethiwe. Njengoba impahla inqwabelana ngaphansi kwepayipi lokugcwalisa eliphakathi nendawo, yakha ikhoni enomthambeka obekwe yi-engeli yokuphumula yempahla (ngokuvamile 25°–40° yezimpushana namaswidi). Ikhona yomthamo olahlekile phezu kwendawo yokugcwalisa emaphakathi kufanele isuswe kumthamo oyisilinda.
Umhosho noma ingaphansi kwesigaxa sengeza ivolumu futhi, kodwa ingxenye engaphezulu kwesiphuma ehamba ngamandla adonsela phansi iyona kuphela ebhekwa njengekhona ukusetshenziswa. Amaphakethe angasebenzi kusilo enomphetho oyisicaba angagcina u-3–8% wevolumu ephelele engakaze ikhishwe, futhi lokho kubanjwa kufanele kuhlelwe, hhayi ukushaywa indiva, ngoba kumelela imali ekhokhiwe kodwa engakaze ibuyiswe.
Indlela Ejwayelekile Yokulinganisa Yengeza Ivolumu Yesilinda KwiVolumu Yomhosho
Ivolumu ephelele egciniwe iyivolumu yomzimba oyisilinda kanye nevolumu yomhosho oyisigaxa, ngayinye ilungiswa ngemikhawulo yokugcwalisa. Esilindeni esime mpo esinobubanzi D nokuphakama kohlangothi oluqondile H:
· Ivolumu yesilinda V_cyl = π × (D/2)² × H
· Ivolumu yesigaxa (umhosho) V_hop = (π/3) × (D/2)² × h_hop, lapho i-h_hop iwukujula komhosho
Umthamo osebenzisekayo = V_cyl (kuze kufike emkhawulweni wokugcwalisa) + V_hop (ingxenye egeleza) − ukulahleka kwe-repose − izikhala ezingasebenzi. Isibali somthamo we-silo esisebenzayo siphinda le geometri kumadaya amakhulu angaba khona futhi sibike isisindo ngokuxinanisa komthamo wephrojekthi, sivumele umthengi ukuthi akhethe ipheya ledayamitha-nobude elilingana nendawo kanye nokuhlelwa kokuphatha.
Idayamitha (m) | Ukuphakama okuqondile (m) | Umthamo wesilinda (m³) | Cishe okusetshenziswayo @90% ukugcwaliswa (m³) |
8 | 12 | 603 | ~540 |
12 | 14 | 1,584 | ~1,420 |
18 | 16 | 4,071 | ~3,650 |
25 | 18 | 8,836 | ~7,950 |
Kumthamo ohlosiwe kasimende ongu-1,000 t ku-1,400 kg/m³, umthamo omsulwa ngu-714 m³; isilo esingububanzi obungu-12 m esinokuphakama okuqondile cishe okungu-8 m kanye ne-hopper siyayifinyelela ngaphakathi kwendawo encane, kuyilapho ithani elifanayo lomlotha wendiza ku-700 kg/m³ lidinga cishe umthamo ophindwe kabili kanye negobolondo elibanzi noma elide.
Isilinganiso Sokuphakama Kuya Kububanzi Siqhuba Isidingo Sesakhiwo Nokuzamazama Komhlaba
Ama-silo amade nezacile akhanga imithwalo ephakeme yokugoqa nokugingqika kunalawo amafushane anevolumu efanayo. Isilinganiso sobude nobubanzi (H/D) esingaphezu cishe kuka-3 sihlanganisa umoya ovundlile nokugunda komhlaba kugxilise egobolondweni elingezansi nangendandatho yesisekelo, okwandisa ukujiya kodonga nezidingo zamabhawodi okubopha.
I-ASCE 7 ichaza indawo yomthwalo womoya nokuzamazama komhlaba, i-EN 1991-1-4 inikeza imodeli yengcindezi yomoya yamagobolondo ayisilinda, kanti i-EN 1998-4 ibhekana nesenzo sokuzamazama komhlaba kuma-silo okuhlanganisa umphumela wokubamba kwesisindo esigciniwe nokuguquguquka kodonga. Ukugcina i-H/D kusigaba esingu-1.5–2.5 kuma-silo ensimbi aboshiwe kuwumthetho ojwayelekile wesithupha olinganisa izindleko zezinto zokwakha nesidingo somthwalo endaweni ejwayelekile; izindawo ezinokuzamazama komhlaba okuphezulu zingase ziphushise abaklami bangqamule kumagobolondo amafushane naphanzi.
Ukulinganisa Kufanele Kuqinisekiswe Ngamakhodi Emithwalo Esebenzayo Nengasebenzi
Ijiyometri iyodwa ayisona isicaciso kuze kube yilapho udonga, uphahla kanye nesisekelo kufakazelwa ngokumelene nezinhlanganisela zomthwalo ezilawulayo. Umthamo obaliwe unquma umthwalo oqondile (igobolondo elifile kanye nempahla ephilayo) kanye nomthwalo ovundlile (umoya, ukuzamazama komhlaba, ukukhishwa okungajwayelekile), futhi lokho kuqhubela phambili ukujiya kwepuleti legobolondo, izinga lamabhawudi kanye nesisindo sesisekelo.
I-ISO 28765 ihlinzeka ngohlaka lokuklama lwamathangi ahlanganisiwe e-vitreous-enamel (GFS) ngaphansi kwalezi zenzo ezihlanganisiwe, futhi izimo zomthwalo ezifanayo ziyasebenza kumasilo ahlanganisiwe ane-enamel-coated kanye ne-galvanized. Linganisa ijiyometri kuqala, bese uhlola igobolondo—hhayi okuphambene—ngoba udonga oluncane lwehluleka ukuhlolwa kwekhodi kungakhathaliseki ukuthi izibalo zevolumu zibukeka zihlanzekile kangakanani.
Icala Lomsebenzi
