Zowonjezera zosiyanasiyana, kuphatikizapo zinthu zamadzimadzi ndi ufa, zingathenso kuphatikizidwa muzosakaniza.

Pali mitundu itatu yodziwika bwino ya zomera zosakaniza phula phula pano: kusakaniza kwa batch, kusakaniza kwa ng'oma, ndi kusakaniza kwa ng'oma kosalekeza. Mitundu itatu yonseyi imakhala ndi cholinga chomwecho, ndipo kusakaniza kwa asphalt kuyenera kukhala kofanana mosasamala kanthu za mtundu wa zomera zomwe zimagwiritsidwa ntchito popanga. Mitundu itatu ya zomera imasiyana, komabe, pakugwira ntchito ndi kuyenda kwa zipangizo, monga momwe tafotokozera m'magawo otsatirawa.

Batch Mix Asphalt Chomera
Chomera chosakaniza phula ndi chida chofunikira pakampani iliyonse yomanga misewu. Ntchito iliyonse ya asphalt batch mix plant ili ndi ntchito zambiri. Zomera za Asphalt Batch zimapanga phula losakanizika lotentha mumagulu angapo. Zomera zosakaniza izi zimatulutsa phula lotentha mopitilira. Ndikotheka kusintha ndikugwiritsa ntchito zidazi popanga phula losakanizika lotentha pogwiritsa ntchito zinthu zobwezerezedwanso. Zomera zamtundu wa batch zimakhala ndi zosiyana zomwe zimalola kuwonjezera kwa RAP (Reclaimed asphalt pavement). Zigawo za chomera chosakanikirana cha asphalt batch ndi: makina oziziritsa, makina operekera phula, chowumitsira chophatikiza, nsanja yosanganikirana, ndi njira yowongolera mpweya. Nyumba yosungiramo zinthu zakale imakhala ndi elevator yotentha, chotchingira chotchinga, ma bin otentha, choyezera choyezera, chidebe choyezera phula, ndi pugmill. Kuphatikizika komwe kumagwiritsidwa ntchito posakaniza kumachotsedwa m'matangadza ndikuyikidwa mu nkhokwe zamadzi ozizira. Magulu amitundu yosiyanasiyana amagawidwa m'mabini awo pophatikiza kukula kwa kutsegula kwa chipata pansi pa bini iliyonse ndi liwiro la lamba wotumizira pansi pa nkhokwe. Nthawi zambiri, lamba wa feeder pansi pa nkhokwe iliyonse amayika chophatikiza pa chotengera chosonkhanitsira chomwe chili pansi pa nkhokwe zonse zoziziritsa kukhosi. Kuphatikizikako kumasamutsidwa ndi conveyor yosonkhanitsa ndikusamutsira ku conveyor yolipira. Zinthu zomwe zili pa conveyor yolipiritsa zimanyamulidwa kupita ku chowumitsira chophatikiza.

Chowumitsira chimagwira ntchito motsatana. Kuphatikizikako kumalowetsedwa mu chowumitsira kumapeto chakumtunda ndipo kumasunthidwa pansi pa ng'oma ndi kuzungulira kwa ng'oma (kuthamanga kwa mphamvu yokoka) ndi kasinthidwe ka ndege mkati mwa chowumitsira chozungulira. Chowotcha chimakhala kumapeto kwenikweni kwa chowumitsira, ndipo mpweya wotuluka kuchokera ku kuyaka ndi kuyanika kumapita kumapeto kwa chowumitsira, motsutsana (kutsutsa) kutuluka kwa aggregate. Pamene chiwombankhanga chikugwedezeka kupyolera mu mpweya wotulutsa mpweya, zinthuzo zimatenthedwa ndikuuma. Chinyezi chimachotsedwa ndikutuluka mu chowumitsira ngati gawo la mpweya wotulutsa mpweya.

Chowotcha, chowuma chophatikizika chimatulutsidwa kuchokera ku chowumitsira kumapeto kwenikweni. Kuphatikizika kotentha nthawi zambiri kumanyamulidwa pamwamba pa nsanja yosakanikirana ndi ndowa. Ikatuluka mu elevator, chophatikiziracho nthawi zambiri chimadutsa pagulu la zowonera zomwe zimagwedezeka kulowa, nthawi zambiri, imodzi mwa nkhokwe zinayi zosungirako zotentha. Zinthu zabwino kwambiri zophatikizira zimadutsa molunjika pazithunzi zonse mu bin yotentha ya No. 1; ma coarser aggregate particles amasiyanitsidwa ndi
zowonetsera zazikulu zosiyanasiyana ndi kuikidwa mu imodzi mwa nkhokwe zina zotentha. Kupatukana kwa aggregate mu nkhokwe zotentha kumadalira kukula kwa zotseguka pazenera zomwe zimagwiritsidwa ntchito pazenera lazenera ndi kugawanika kwa aggregate mu nkhokwe zoziziritsa kukhosi.

Zowotchera, zowumitsidwa, ndi zosinthidwanso zimasungidwa m'mabini otentha mpaka zitatulutsidwa kuchokera pachipata cha pansi pa bini iliyonse kukhala choyezera choyezera. Gawo lolondola la aggregate iliyonse limatsimikiziridwa ndi kulemera kwake.
Panthawi imodzimodziyo kuti chiwerengerocho chikugawidwa ndikuyesedwa, phulalo likuponyedwa kuchokera ku thanki yake yosungiramo katundu kupita ku ndowa yolemetsa yomwe ili pa nsanja pamwamba pa pugmill. Kuchuluka koyenera kwa zinthu kumayezedwa mumtsuko ndikusungidwa mpaka kukhuthulidwa mu pugmill. Aggregate mu weigh hopper amatsanuliridwa mu twin-shaft pugmill, ndipo tizigawo tosiyanasiyana tophatikizana timasakanizidwa kwa nthawi yaifupi kwambiri - nthawi zambiri zosakwana masekondi asanu. Pambuyo pa nthawi yosakaniza yowuma iyi, phula lachidebe choyezera limatulutsidwa.

mu pugmill, ndipo nthawi yonyowa-yosakaniza imayamba. Nthawi yosakaniza yosakaniza phula ndi aggregate sayenera kukhala yoposa yomwe imafunika kuti muvale tinthu tating'onoting'ono ndi filimu yopyapyala ya zinthu za asphalt-kawirikawiri pa masekondi 25 mpaka 35, ndi mapeto apansi amtunduwu. kukhala kwa pugmill yomwe ili bwino. Kukula kwa mtanda wosakanikirana mu pugmill kungakhale mumtundu wa matani 1.81 mpaka 5.44 (matani 2 mpaka 6).
Kusakaniza kumalizidwa, zipata pansi pa pugmill zimatsegulidwa, ndipo kusakaniza kumatulutsidwa mu galimoto yonyamula katundu kapena mu chipangizo chonyamulira chomwe chimanyamula kusakaniza kupita ku silo komwe magalimoto amanyamulidwa mu batch fashion. Pazomera zambiri zamagulu, nthawi yofunikira kuti mutsegule zipata za pugmill ndikutulutsa kusakaniza ndi pafupifupi 5 mpaka 7 masekondi. Nthawi yonse yosakaniza (nthawi yosakaniza yowuma + yonyowa-kusakaniza nthawi + kusakaniza nthawi yotulutsa) kwa batch ikhoza kukhala yochepa ngati masekondi 40, koma kawirikawiri, nthawi yonse yosakaniza ili pafupi masekondi 45.

Malowa ali ndi zida zowongolera mpweya, zomwe zimakhala ndi makina oyambira komanso achiwiri. Bokosi lowuma kapena bokosi logogoda nthawi zambiri limagwiritsidwa ntchito ngati chosonkhanitsa choyamba. Kaya makina otsukira onyowa kapena, nthawi zambiri, makina owuma a nsalu (baghouse) angagwiritsidwe ntchito ngati njira yosonkhanitsira yachiwiri kuti achotse tinthu tating'onoting'ono kuchokera ku mpweya wotuluka kuchokera mu chowumitsira ndikutumiza mpweya wabwino kumlengalenga kudzera mu stack. .
Ngati RAP ikuphatikizidwa mu kusakaniza, imayikidwa mu nkhokwe yosiyana ya chakudya chozizira yomwe imaperekedwa ku zomera. RAP ikhoza kuwonjezeredwa kumagulu atsopano mu imodzi mwa malo atatu: pansi pa elevator yotentha; matumba otentha; kapena, kawirikawiri, chopimitsira sikelo. Kutentha kwa kutentha pakati pa superheated atsopano aggregate ndi reclaimed zakuthupi kumayamba mwamsanga pamene zipangizo ziwiri kukhudzana ndi kupitiriza pa ndondomeko kusakaniza mu pugmill.


Drum Mix Asphalt Chomera
Poyerekeza ndi mtundu wa batch, drum mix asphalt plant ili ndi kutaya pang'ono kwa kutentha, mphamvu zochepa zogwirira ntchito, palibe kusefukira, fumbi lochepa lowuluka komanso kuwongolera kutentha kokhazikika. Dongosolo lowongolera limasinthiratu kuchuluka kwamayendedwe a asphalt malinga ndi kuchuluka kwamayendedwe ophatikizika komanso kukhazikitsidwa kwa asphalt-aggregates ratio, kuti zitsimikizire kutulutsa kofananako. Asphalt drum mix plant ndi mitundu ya zomera zomwe zimagawidwa ngati zomera zosakaniza mosalekeza, zimapanga phula losakaniza lotentha mosalekeza.

Kawirikawiri machitidwe ozizira odyetsa pa HMA batch ndi zomera zosakaniza ng'oma ndizofanana. Iliyonse imakhala ndi nkhokwe zodyeramo madzi ozizira, zotumizira chakudya, chotengera chosonkhanitsa, ndi chotengera cholipirira. Pa zomera zambiri zosakaniza ng'oma ndi zomera zina zamagulu, chophimba cha scalping chimaphatikizidwa mu dongosolo nthawi ina. Ngati RAP ikudyetsedwanso mufakitale kuti ipange zosakaniza zobwezerezedwanso, nkhokwe zowonjezera zoziziritsa kuziziritsa kapena nkhokwe, lamba wa feeder ndi/ kapena chotengera cholumikizira, chotchinga cha scalping, ndi chotengera chachaji ndizofunikira kuti mugwiritse ntchito zowonjezera. Zomera zosakaniza ng'oma zimakhala ndi zigawo zazikulu zisanu: makina odyetsa ozizira, makina operekera phula, chosakaniza ng'oma, surge kapena silos yosungirako, ndi zida zowongolera mpweya.

Zosungirako zoziziritsa kukhosi zimagwiritsidwa ntchito polinganiza zinthu ndi mbewu. Lamba wowonjezera liwiro losinthasintha amagwiritsidwa ntchito pansi pa nkhokwe iliyonse. Kuchuluka kwa aggregate kuchokera ku bin iliyonse kungathe kulamulidwa ndi kukula kwa chipata chotsegula ndi liwiro la lamba wodyetsa kuti apereke zolondola za zipangizo zosiyana. Kuphatikizika kwa lamba aliyense wa feeder kumayikidwa pa chotengera chosonkhanitsa chomwe chimayenda pansi pa nkhokwe zonse zoziziritsa kukhosi. Zomwe zimaphatikizidwa nthawi zambiri zimadutsa pazenera la scalping ndiyeno zimasamutsidwa ku chotengera cholipiritsa kuti chisamutsidwe kupita ku chosakaniza ng'oma.

Chotengera cholipiritsa chimakhala ndi zida ziwiri zomwe zimagwiritsidwa ntchito kudziwa kuchuluka kwa zinthu zomwe zimaperekedwa kufakitale: mlatho woyezera pansi pa lamba wotumizira amayesa kulemera kwa aggregate akudutsa pamwamba pake, ndipo sensa imazindikira kuthamanga kwa lamba. Miyezo iwiriyi imagwiritsidwa ntchito kuwerengera kulemera konyowa kwa aggregate, mu matani (matani) pa ola, kulowa mu chosakaniza ng'oma. Makompyuta a chomera, okhala ndi kuchuluka kwa chinyezi pagulu lomwe amaperekedwa ngati mtengo wolowera, amasintha kulemera konyowa kukhala kowuma kuti adziwe kuchuluka koyenera kwa asphalt komwe kumafunikira pakusakaniza.

Chosakanizira cha ng'oma wamba ndi njira yoyendera limodzi - mpweya wotuluka ndi zophatikiza zimayenda mbali imodzi. Chowotchacho chili kumapeto chakumtunda (kumaliza kolowera) kwa ng'oma. Zophatikizazo zimalowa mu ng'oma mwina kuchokera pa chute pamwamba pa chowotcha kapena pa Slinger conveyor pansi pa chowotcha. Kuphatikizikako kumasunthidwa pansi pa ng'oma ndi kuphatikiza kwa mphamvu yokoka ndi kasinthidwe ka ndege zomwe zili mkati mwa ng'oma. Pamene akuyenda, aggregate amatenthedwa ndipo chinyezi chimachotsedwa. Chophimba chowundana cha aggregate chimamangidwa pafupi ndi pakati pa kutalika kwa ng'oma kuti zithandizire potumiza kutentha.

Ngati RAP iwonjezeredwa kumagulu atsopano, imayikidwa kuchokera ku nkhokwe yake yozizirira ndikusonkhanitsa /charging conveyor system munjira yomwe ili pafupi ndi pakati pa kutalika kwa ng'oma (kachitidwe kagawidwe ka chakudya). Pochita izi, zinthu zobwezeretsedwa zimatetezedwa ku mpweya wotentha kwambiri ndi chophimba cha aggregate yatsopano kumtunda kwa malo olowera a RAP. Mukasakaniza ndi zinthu zambiri za RAP zimagwiritsidwa ntchito, ndizowonjezereka kuti RAP idzatenthedwa kwambiri panthawiyi. Izi zitha kupangitsa kuti utsi utuluke m'ng'oma kapena kuwonongeka kwa RAP.

Zophatikiza zatsopano ndi zobwezeredwa, ngati zitagwiritsidwa ntchito, zimasunthira limodzi kuseri kwa ng'oma. Asphalt imakokedwa kuchokera ku tanki yosungiramo ndi mpope ndikudyetsedwa kudzera pa mita, pomwe phula loyenera limatsimikiziridwa. Zomangirazo zimaperekedwa kudzera mu chitoliro kumbuyo kwa ng'oma yosakanizira, pomwe phula limayikidwa pagulu. Kuphimba kwa aggregate kumachitika pamene zipangizo zimagwedezeka pamodzi ndikusunthira kumapeto kwa ng'oma. Ma mineral filler kapena baghouse faini, kapena zonse ziwiri, zimawonjezeredwa kumbuyo kwa ng'oma, mwina kale kapena molumikizana ndi kuwonjezera kwa phula.

Kusakaniza kwa asphalt kumayikidwa mu chipangizo chonyamulira (chotengera chonyamulira lamba, chonyamulira lamba, kapena chikepe cha ndowa) kuti chinyamukire ku silo yosungira. Silo imatembenuza kusakanikirana kosalekeza kukhala kanjira kothamangira m'galimoto yonyamula.

Nthawi zambiri, zida zamtundu womwewo zomwe zimagwiritsidwa ntchito popanga drum-mix plant monga pa batch plant. Chotolera chowuma choyambirira komanso makina ochapira onyowa kapena chotolera chachiwiri cha baghouse angagwiritsidwe ntchito. Ngati makina otsukira onyowa agwiritsidwa ntchito, chindapusa chosonkhanitsidwa sichingabwezeretsedwenso ndikusakanikirana ndikuwonongeka; ngati thumba la baghouse likugwiritsidwa ntchito, chindapusa chosonkhanitsidwa chikhoza kubwezeredwa chonse kapena mbali yake ku ng'oma yosakaniza, kapena zitha kuonongeka.
