Lub hom phiaj ntawm asphalt nroj tsuag yog tsim kom muaj kub sib tov asphalt. Cov nroj tsuag no siv cov sib sau ua ke, xuab zeb, bitumen thiab lwm yam khoom siv tshwj xeeb los tsim asphalt, uas tseem hu ua blacktop lossis asphalt pob zeb.
Lub luag haujlwm tseem ceeb ntawm kev sib xyaw asphalt cog yog tias nws ua kom sov cov khoom sib xyaw thiab tom qab ntawd sib tov nrog cov bitumen thiab lwm yam nplaum los ua kom kub sib xyaw asphalt. Qhov ntau thiab qhov xwm txheej ntawm qhov sib sau ua ke yog nyob ntawm cov kev xav tau tshwj xeeb. Nws tuaj yeem yog cov khoom siv ib leeg lossis cov khoom sib xyaw ua ke ntawm ntau cov khoom sib txawv, nrog rau kev sib xyaw ntawm cov nplua thiab ntxhib hais.
Hom Asphalt Nroj Tsuag
Kev ua haujlwm ntawm cov nroj tsuag asphalt kuj nyob ntawm hom asphalt nroj tsuag. Feem ntau, muaj ob yam loj ntawm asphalt nroj tsuag. Lub hom phiaj tseem ceeb ntawm tag nrho cov hom no yog los tsim kub mix asphalt. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm cov nroj tsuag no raws li txoj hauv kev uas lawv ua tiav cov txiaj ntsig xav tau thiab hauv kev ua haujlwm tag nrho.
1. Batch Mix Cog
Muaj ntau ntau yam koom nrog hauv asphalt qhob pob zeb sib xyaw cog. Ib qho tseem ceeb tshaj plaws ntawm cov nroj tsuag zoo li no yog kev siv cov khaub thuas sib xyaw feeder bins los khaws thiab pub cov aggregates hauv cov khoom sib txawv raws li lawv qhov ntau thiab tsawg. Tsis tas li ntawd, lawv muaj ib qho kev pabcuam pub khoom noj hauv qab txhua lub thawv.
Conveyor yog siv los hloov cov aggregates ntawm ib lub conveyor mus rau lwm qhov. Thaum kawg, tag nrho cov khoom raug xa mus rau lub nruas kom qhuav. Txawm li cas los xij, cov sib sau ua ke kuj yuav tsum tau mus dhau ntawm lub vibrating screen kom ntseeg tau tias kev tshem tawm cov khoom loj.
Lub tshuab ziab khaub ncaws muaj lub tshuab hluav taws xob kom tshem tawm cov dej noo thiab ua kom sov cov khoom sib xyaw kom ntseeg tau tias qhov sib xyaw zoo tshaj plaws. Lub elevator yog siv los nqa cov aggregate mus rau saum tus pej thuam. Lub pej thuam muaj peb lub ntsiab: lub vibrating npo, kub bins thiab chav sib tov. Thaum cov aggregates raug cais los ntawm lub vibrating npo raws li lawv qhov loj me, lawv tau muab khaws cia rau hauv ib ntus rau hauv ntau qhov chaw hu ua kub bins.
Cov thawv kub khaws cov khoom sib xyaw rau hauv cov thawv cais rau ib lub sijhawm thiab tom qab ntawd tso lawv mus rau hauv chav sib xyaw. Thaum cov aggregates raug hnyav thiab tso tawm, bitumen thiab lwm yam ntaub ntawv tseem ceeb yog feem ntau tso rau hauv chav tsev sib xyaw thiab.
Hauv feem ntau cov kev lag luam, kev txhim kho cov pa phem hauv huab cua yog qhov tseem ceeb los xyuas kom muaj kev ruaj khov thiab kev nyab xeeb ntawm cov nroj tsuag asphalt. Feem ntau, lub hnab lim dej yog siv los cuab cov plua plav. Cov plua plav feem ntau rov qab siv dua hauv lub elevator.
2. Nruas Mix Cog
Nruas mix asphalt nroj tsuag muaj ntau qhov zoo sib xws rau batch mix nroj tsuag. Cov khib nyiab txias yog siv rau hauv cov nruas sib xyaw. Ntxiv mus, cov txheej txheem yog zoo tib yam rau batch mix cog kom txog rau thaum cov aggregates nkag mus rau hauv lub nruas tom qab mus los ntawm lub vibrating screen cais lawv raws li lawv qhov ntau thiab tsawg.
Lub nruas muaj ob lub luag haujlwm tseem ceeb: ziab thiab sib tov. Thawj feem ntawm lub nruas yog siv los ua kom sov cov aggregates. Thib ob, aggregates yog tov nrog bitumen thiab lwm yam khoom lim. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub nruas sib xyaw asphalt cog yog ib qho kev sib xyaw txuas ntxiv. Yog li ntawd, cov thawv me me lossis cov khoom siv tsim nyog yog siv los tuav cov khoom kub asphalt.
Txij li thaum bitumen sib tov nyob rau tom qab theem ntawm kev tsim khoom, nws yog thawj zaug muab cia rau hauv cov tso tsheb hlau luam cais thiab muab tso rau hauv qhov thib ob ntawm lub nruas. Nws yog ib qho tseem ceeb kom tswj tau cov huab cua zoo kom tsis txhob muaj kuab paug. Rau lub hom phiaj no, cov khoom siv tswj kev ua qias tuaj zoo li cov ntaub ntub dej ntub dej lossis cov hnab lim dej feem ntau yog siv hauv nruas sib xyaw asphalt nroj tsuag.
Nws yog pov thawj tias ob qho tib si ntawm cov nroj tsuag no muaj qee qhov sib xyaw thiab cov txheej txheem ua haujlwm. Piv txwv li, pub bins yog qhov tseem ceeb hauv ob qho tib si batch thiab cov nroj tsuag txuas ntxiv. Ib yam li ntawd, lub vijtsam vibrating tseem ceeb hauv txhua hom asphalt cog. Lwm qhov chaw ntawm cov nroj tsuag xws li thoob elevators, sib tov units xws li nruas, hnyav hoppers, cia tso tsheb hlau luam, hnab lim thiab tswj alarm kuj tseem ceeb nyob rau hauv ob qho tib si batch mix cog thiab nruas mix cog.
Lub hom phiaj ntawm kev sib txawv ntawm ob hom loj ntawm asphalt nroj tsuag yog qhia tias ob hom nroj tsuag tsim tau zoo-zoo kub sib tov asphalts, txawm tias lawv siv cov kev khiav hauj lwm sib txawv.
Hom asphalt cog uas ib lub tuam txhab xav teeb tsa yog nyob ntawm lawv txoj kev lag luam, kev siv nyiaj txiag thiab tag nrho cov kev cai thiab cov kev cai ntawm cheeb tsam kev lag luam. Yog xav paub ntxiv
Cov ntsiab lus
Asphalt nroj tsuag tsim kub sib tov asphalt siv aggregates, xuab zeb, bitumen, thiab lwm yam ntaub ntawv. Cov txheej txheem suav nrog cua sov cov aggregates thiab sib tov nrog bitumen los tsim asphalt. Muaj ob lub ntsiab ntawm asphalt nroj tsuag: batch mix thiab nruas mix.
Batch mix nroj tsuag tsim asphalt nyob rau hauv batch, siv ib tug ntau-kauj ruam txheej txheem uas muaj xws li txias aggregate feeders, vibrating screen, thiab mixing units. Nruas mix nroj tsuag, ntawm qhov tod tes, ua haujlwm tsis tu ncua, sib xyaw kom qhuav thiab sib xyaw hauv ib lub nruas. Ob hom nroj tsuag muab cov asphalt zoo, nrog rau kev xaiv nyob ntawm kev xav tau ntawm kev lag luam, peev nyiaj, thiab kev cai.
