Isiphetho:Ekwakheni i-asphalt ephezulu ye-expressway, ukwahlukaniswa kwezinto ezisetshenziswayo kuyinto eyinhloko ekugcineni ukukhuluka kwe-asphalt mixture, futhi kuyinto esisisekelo kakhulu ekuthinteni ukukhuluka kokwakhiwa.

Ekwakheni i-asphalt ephezulu ye-expressway, ukwahlukaniswa kwezinto ezisetshenziswayo kuyinto eyinhloko ekugcineni ukukhuluka kwe-asphalt mixture, futhi kuyinto esisisekelo kakhulu ekuthinteni ukukhuluka kokwakhiwa. Lesi sihloko siwabelana ngenqubo, i-tekhnoloji ebalulekile, ukulungisa imishini kanye nezinto ezibalulekile zokusebenza kwesihlabathi kanye nezinto ezisetshenziswayo.

Imiphumela yokusebenza

(1) Khetha umthombo wempahla yomgodi bese ukhulula umhlabathi oqoshwe phakathi, izitshalo ezimhlophe, njll., ukuqinisekisa ukuthi impahla esisisekelo ifanelekela izidingo;

(2) Hlela indawo yokusebenza ngokuhlakanipha bese ubeka ama-crusher nama-vibrating screen;

(3) Qinisekisa izinga lokukhiqiza kanye nokhutshwa kwemishini yokucrusher ngokuhambisana nezindinganiso nemikhuba yempahla ngayinye;

(4) Ngokuhambisana nezibalo zokuhlola kanye nokuhlolwa kabusha, qinisekisa uhlobo lwescreen, ubukhulu bezinhlayiya zescreen, indawo yokubeka i-screen, isimo sokuhlelwa kwe-mesh kanye nobukhulu ukuze kuhlangabezane nezidingo.

(5) Ukucwiliswa kwempahla engenayo, ukwenza izilingo njalo, nokuhlela nokulondoloza izixazululo zokukhiqiza ngokuvumelana nesimo sezinto.

Ikhono elibalulekile lokukhiqiza ama-aggregate

Ikhono elibalulekile lokukhiqiza inqubo yama-aggregate ikakhulukazi linama-3 amakhono: inqubo yokusebenza, ukwakheka kwe-vibrating screen, ukulungisa izixazululo. Lezi zikhono ezintathu eziyisisekelo zifanekisela nezizathu eziyinhloko ezithinta ukulinganisela kokuhlobisa kwempahla yomgodi. Ukuphathwa kwenqubo ehambisanayo kuhlukaniswe njengalandelayo.

(1)Ukucaciswa kwekhwalithi yokushicilela

Kukhona izinhlobo ezintathu zezindlela zokusebenza ezivame ukusetshenziswa ekukhiqizeni ama-aggregate emgwaqweni oqhubekayo:

  • eyokuqala yindlela yokushicilela ezinyangeni ezimbili, umshicileli we-jaw → umshicileli we-impact noma i-cone → isikrini esijikijayo;
  • eyesibili yindlela yokushicilela ezinyangeni ezintathu, umshicileli we-jaw → umshicileli we-impact, i-hammer noma i-cone → umshicileli we-impact noma i-hammer (ukuhlobisa izinhlayiya) → isikrini esijikijayo;
  • eyesithathu yindlela yokushicilela ezinyangeni ezine, umshicileli we-jaw → umshicileli we-impact, i-hammer noma i-cone → umshicileli we-impact noma i-hammer (ukuhlobisa izinhlayiya) → umshicileli we-impact → isikrini esijikijayo.

(2) Ukuqondisa uhlobo lomaciki

Kukhona izinhlobo eziningi zamaciki wemithombo, ezisetshenziswa kakhulu yi-jaw crusher, i-cone crusher noma i-hammer crusher, i-impact crusher, njll. Ngalomaciki ngalinye linezinzuzo zalo, okuqondisiwe ngokusekelwe ezidingweni zolwimi lwempahla ephathelene nomsebenzi, isimo somthombo kanye nezici zokusebenza endaweni.

Ngesikhathi esifanayo, ukuze lawulwe ukuba khona kwe-dust ezimvelweni ezithuthukisiwe ngesikhathi sokuthuthukisa izinto eziqinile, okufanele kongezwe yikho isixazululo se-induced air dust removal emsebenzini noma esimvelweni esiphelile.

(3) Uhlobo lwesikrini

Izinhlobo ezivame ukusetshenziswa zesikrini ziyisikrini esijikijaka, isikrini esibuthwa kanye nesisikrini esimnyama, zonke lezi zinethonya elihle lokukrinja. Ngesikhathi sikhetha uhlobo lwesikrini, kufanele sizicabangele izimo zendawo.

Ngemva kokubona uhlobo lwesikrini, kudingeka kuqondile ukulinganisa isivinini sokujikeleza kwesikrini esijikijaka kanye nomqondo wokunamathisela kwesikrini ngokuvumelana nenani lokukhishwa okubekwe. Umqondo wokunamathisela oqine kanye nesisivinini esikhulu sokujikeleza kwesikrini, okukhulu ukukhishwa kwezinto ezihlanganisiwe, futhi okuphambene nalokho.

(4) Ukubonaqaphela ipharamitha ngayinye ye-vibrating screen

I-aperture ye-screen mesh isimiswa ngokuvumelana nezidingo ze-aggregate, okuvamile ukuba kube yi-2-5mm enkulu kunesayizi olukhulu lomthamo we-aggregate okumelwe ukuba lunikezwe yizidingo. Izilungiselelo ezithile kufanele zilungiswe ngokufanele ngokuvumelana nobukhulu, inani le-aggregate kanye nokuqondile kwe-vibrating screen. Uma i-aggregate iyingqayizivele futhi inani likhulu, i-aperture ye-screen mesh kufanele ikhuliswe ngokufanele; uma ikhona i-inclination angle enkulu yokuthuthumela, i-aperture

Ngesikhathi esifanayo, ubude be-mesh yesikrini kufanele sibekwe ngokuvumelana nokuqina nokuqukethwe kwesigaba ngasinye sama-aggregate. Okokuqala, qothula ingxenye yama-aggregate ebhentshini lokuthutha kwesigaba sokuqala (okungukuthi, ibhensi lokuthutha kwesigaba sokuqala ngemuva kokucisha), bese uyisikrina ukuze ubone ukuqukethwe nokuqondisiwe kwesigaba ngasinye sama-aggregate. Uma ukuqukethwe kwesigaba esithile sama-aggregate kuyikhulu, khulisa ubude be-mesh yesikrini ngokufanele; ama-aggregate amancane kufanele futhi akhuliswe ubude be-mesh yesikrini. Ngaphandle kwalokho, kunciphisa ubude be-mesh yesikrini. Indlela yokubeka i-mesh yesikrini iwukusebenzisa...

Izakhiwo zokugcina ezizalwa ngezakhiwo ezingenhla azikhohlwa ngumthelela ofakthali abalandelayo, kodwa zihlobene futhi zihlanganisa. Ngakho-ke, ekusebenzeni kokuhlela, kuyadingeka ukuba kube nokuhlelwa okuningi okuhlangene. Ngokwezimo zokuhlolwa kwangempela, omunye noma amaningi ama-parameter ahlolwa kuze kube yilapho izakhiwo ezifanele zikhona.

Ukubuyekezwa kwezinhlelo

Izakhiwo ezizalwa azikhohlwa kuphela ngokuhlolwa kwesikrini esijikijwayo, kodwa futhi zihlobene kakhulu nenkambiso ye-mechanical yokucisha umonakalo.

Kunezindawo ezimbili zokuthinta ezincishiseni zokuthinta ukuze zenze amaqembu amabili okucisha. Ukulungisa inqola yensimbi kungashintsha isikhala phakathi kweplate yokuthinta nenqola yokuthinta, ngaleyo ndlela kwashintsha izinga lobungako bemicu evelayo. Ngokuvamile, ipuleti yokuqala yokuthinta inesiqephu esikhulu njengesigaba sokuqhekeza okukhulu; ipuleti yesibili yokuthinta inesiqephu esincane njengesigaba sokuqhekeza okulinganayo nokulinganiselwe.

Lungisa isikhala phakathi kwemiplate emibili yokuthinta ngaphambi kokusebenza okuvamile, ukuze imicu evelayo ifane nokulungiselelwa kwengxenye eledlula ngokulinganiselwa.

Njengoba nje, uma kusetshenziswa izendlalelo zangaphakathi nezangaphansi ze-aggregate egameni le-expressway, umkhumbi phakathi kwephelela lokuqala lokukhanda ne-blow bar uqondiswe ku-35mm, kanti umkhumbi phakathi kwe-impact plate yesibili ne-blow bar uqondiswe ku-25mm; uma kusetshenziswa izendlalelo eziphezulu ze-aggregate egameni le-expressway, umkhumbi phakathi kwe-impact plate yokuqala ne-blow bar uqondiswe ku-30mm, kanti umkhumbi phakathi kwe-impact plate yesibili ne-blow bar uqondiswe ku-20mm.

Ezinye izimboni zokucwilisa amaqhwa nokususa amatshe zilungisa umkhumbi phakathi kwe-impact plate ne-blow bar ukuze khulisa amathuba okukhishwa kwamatye ahlakazekile.

Izindawo zokusebenza

(1) Hlola umthombo wempahla, futhi uqeqeshe ukulinganiselwa komthombo nokukhuluka nokunye kolwimi;

(2) Indawo iqinisekiswe, futhi izikhwama zokukhishwa zibekwe ukuvimbela ukungcoliswa okwesibili kwezinto ezinkulu;

(3) Lapho uhlanganisa isikhwama sokuqhekeza nesikhwama sokugcina esiqeshwe, ukukhuluka kokuthutha izinto ezinkulu zokwenza umsebenzi kuya eqeshweni kufanele kuqashelwe ngokugcwele, futhi isikhwama sokugcina kufanele sabelwe ngokufanele ngokuvumelana nenani lokukhiqiza kwempahla ngayinye eyodwa.

(4) Ngokomphumela oqondiswe ngayo, qamba ubukhulu be-mesh obufanele, ubude besikrini, ukuqinisekisa ukuthi i-aggregate eyodwa yingcezu ifanelekela izidingo zomkhawulo;

(5) Ukuze kunciphisa uthuli futhi uqedele ukwahlukanisa, faka isikhululo sokuphonsa umoya oqhekezelayo nokuqeda uthuli, bese ufaka amanzi amaningi, uma kudingeka.

(6) Nsukukahleni ukukhiqiza ngesizini yemvula, vala isikrini esijikijaka kahle ukuvimbela ukwahlukaniswa okungaphelele ngesikhathi sokuqhekeza;

(7) I-aggregate egedile kufanele ivaliwe noma yakhiwe ngesikhala ukuze ihlale iomile, ukuze kube nokuthuthukiswa kwamandla ngesikhathi sokusetshenziswa;

(8) Ngesikhathi sokwenza umsebenzi we-aggregate, ukuphathwa kokukhiqiza kufanele kwenziwe ngokuvumelana nokukhiqiza ngesikhathi sokuhlolwa, ukuze kuqinisekiswe izindinganiso ezimele ze-aggregate eyenziwe.
