Chinangwa chemiti yeasphalt ndechekugadzira inopisa musanganiswa asphalt. Zvidyarwa izvi zvinoshandisa aggregates, jecha, bitumen nezvimwe zvakadaro kunyanya kuwanda kugadzira asphalt, inodaidzwa zvakare kuti blacktop kana asphalt kongiri.
Chiitiko chikuru chechirimwa chekusanganisa asphalt ndechekuti chinopisa maaggregates uye yobva yaasanganisa nebhitumini uye zvimwe zvinhu zvinonamira kuti ibudise inopisa musanganiswa asphalt. Huwandu uye chimiro cheaggregate zvinoenderana nezvinodiwa chaizvo. Inogona kunge iri saizi imwe chete kana musanganiswa wezvakawanda zvinhu zvehukuru hwakasiyana, pamwe nemusanganiswa weakatsetseka uye akaomesesa zvimedu.
Mhando dzeAsphalt Plants
Kushanda kwemiti yeasphalt kunoenderanawo nemhando yemiti yeasphalt. Kazhinji, kune marudzi maviri makuru emiti yeasphalt. Chinangwa chikuru chemhando dzose idzi ndecheku gadzira inopisa musanganiswa asphalt. Nekudaro, pane misiyano yakakosha pakati pezvidyarwa izvi maererano nenzira yavanowana nayo mhedzisiro inodiwa uye mukushanda kwese kwese.
1. Batch Mix Plant
Pane zvinhu zvakati wandei zvinobatanidzwa mu asphalt kongiri batch mix plant. Chimwe chezvinhu zvinonyanya kukosha nezvezvirimwa zvakadaro kushandiswa kweanotonhora aggregate feeder mabhini kuchengetedza uye kudyisa akaunganidzwa muzvikamu zvakasiyana zvichienderana nehukuru hwawo. Pamusoro pezvo, vane bhandi rekubatsira rekudyisa pazasi pebhini rega rega.
Mutakuri anoshandiswa kushandura aggregates kubva kune imwe conveyor kuenda kune imwe. Pakupedzisira, zvinhu zvose zvinoendeswa kune dhiramu yekuomesa. Nekudaro, iwo aggregates anofanirwawo kupfuura nepaiyo vibrating skrini kuti ave nechokwadi chekubviswa kwakaringana kwezvinhu zvakakura.
Iyo dhiramu yekuomesera ine yekupisa yuniti yekubvisa hunyoro uye kupisa iyo yakaunganidzwa kuti ive neyakakwana yekusanganisa tembiricha. Elevator inoshandiswa kutakura maaggregates kusvika pamusoro peshongwe. Iyo shongwe ine matatu makuru mayuniti: inozunguza skrini, inopisa mabhini uye yekusanganisa unit. Kana iwo akaunganidzwa apatsanurwa neiyo vibrating skrini zvinoenderana nehukuru hwayo, anochengetwa kwenguva mumakamuri akasiyana anonzi mabhini anopisa.
Mabhini anopisa anochengeta aggregate mumabhini akaparadzana kweimwe nguva yenguva uye wozoasunungura muchikamu chekusanganisa. Kana maaggregates achiyerwa nekuburitswa, bhitumini nezvimwe zvinhu zvakakosha zvinowanzoburitswa muchikamu chekusanganisa zvakare.
Mumaindasitiri mazhinji, kuisa midziyo yekudzora kusvibiswa kwemhepo kwakakosha kuti tive nechokwadi chekuti zvirimwa zveasphalt zvinogara zviripo uye zvinoenderana nemamiriro ekunze. Kazhinji, bhegi sefa mayuniti anoshandiswa kuteya guruva zvidimbu. Iyo huruva inowanzo shandiswa zvakare muaggregate elevator.
2. Drum Mix Plant
Drum mix asphalt zvinomera zvine zvakawanda zvakafanana kune batch mix zvirimwa. Mabhini anotonhora anoshandiswa mumidziyo yemusanganiswa wedhiramu. Zvakare, maitiro acho akafanana neiyo batch musanganiswa chirimwa kudzamara aggregates apinda mudhiramu mushure mekupinda nepaiyo vibrating skrini kuti aparadzanise iwo pahwaro hwehukuru hwawo.
Dhiramu rine mabasa maviri makuru: kuomesa nekusanganisa. Chikamu chekutanga chedhiramu chinoshandiswa kupisa zvikamu. Chechipiri, zvakaunganidzwa zvakasanganiswa nebhitumini uye mamwe mafirita zvinhu. Izvo zvakakosha kuti uzive kuti chigubhu chinosanganisa asphalt chirimwa chinoramba chichisanganisa chirimwa. Naizvozvo, midziyo midiki kana chinhu chakakodzera chinoshandiswa kubata inopisa musanganiswa asphalt.
Sezvo bhitumini yakasanganiswa pane imwe nguva yekupedzisira yekugadzirwa, inotanga kuchengetwa mumatangi akasiyana uye yozoiswa muchikamu chechipiri chedhiramu. Zvakakosha kuchengetedza mhepo yakakwana kudzivirira kusvibiswa. Nechinangwa ichi, midziyo yekudzora kusvibiswa senge wet scrubbers kana mabhegi mafirita anowanzo shandiswa mudhiramu musanganiswa asphalt zvirimwa.
Zviripachena kuti ese ari maviri emhando yemiti ane zvimwe zvakajairika zvikamu uye maitiro ekushanda. Semuenzaniso, mabhini ekudyisa akakosha mune zvese batch uye zvinoramba zvichirimwa. Saizvozvo, chidzitiro chinozunguza chakakosha mumhando yese yeasphalt chirimwa. Zvimwe zvikamu zvezvirimwa zvakaita sezvikwiriso zvemabhaketi, madhiramu ekusanganisa semadhiramu, mahopi ekuyeresa, matangi ekuchengetedza, mabhegi mafirita uye kabhini yekudzora zvakakoshawo mune ese ari maviri batch musanganiswa chirimwa uye dhiramu musanganiswa chirimwa.
Chinangwa chekusiyanisa pakati pemhando mbiri idzi huru dzemiti yeasphalt kuratidza kuti marudzi ose emiti anobudisa zvakanaka-mhando inopisa inopisa asphalts, kunyange kana vachishandisa maitiro akasiyana-siyana ekushanda.
Mhando yeasphalt chirimwa icho kambani inoda kumisikidza inotsamira zvakanyanya pane yavo bhizinesi zvavanoda, bhajeti uye yakazara mitemo nemirairo yenzvimbo yeindasitiri. Kuti uwane mamwe mashoko
Summary
Asphalt zvirimwa zvinogadzira inopisa musanganiswa asphalt uchishandisa aggregates, jecha, bhitumini, uye zvimwe zvinhu. Maitiro acho anosanganisira kudziyisa akaunganidzwa uye nekuasanganisa nebhitumini kugadzira asphalt. Kune marudzi maviri makuru emiti yeasphalt: batch mix uye dhiramu musanganiswa.
Batch musanganiswa zvirimwa zvinogadzira asphalt mumabhechi, uchishandisa akawanda-nhanho maitiro anosanganisira anotonhora aggregate feeder, vibrating screens, uye kusanganisa mayuniti. Drum mix plant, kune rumwe rutivi, inoshanda nguva dzose, ichibatanidza kuomesa uye kusanganisa mune imwe dhiramu. Marudzi ese ari maviri emiti anopa asphalt yemhando yepamusoro, ine sarudzo zvichienderana nezvido zvebhizinesi, bhajeti, uye mirau.
