Ua ntej, peb yuav tsum txheeb xyuas cov laj thawj tseem ceeb ntawm cov dej ntws hauv asphalt mixing nroj tsuag:
1. Sib tov nyob rau hauv lub txias silo. Feem ntau muaj tsib lossis plaub lub qhov txias txias, txhua qhov uas muaj qhov me me. Yog tias cov ntaub ntawv txias ntawm cov khoom sib txawv sib xyaw lossis ua yuam kev thaum lub sijhawm pub mis, nws yuav ua rau muaj qhov tsis txaus ntawm qee qhov tshwj xeeb hauv ib lub sijhawm, thiab dhau ntawm cov khoom ntawm lwm qhov tshwj xeeb, uas tuaj yeem yooj yim rhuav tshem cov khoom noj ntawm cov khoom noj. kub thiab txias silos.

2. Cov muaj pes tsawg leeg ntawm raw khoom hais ntawm tib specification muaj kuj zoo variability. Txij li thaum muaj ob peb lub pob zeb loj hauv kev ua lag luam, qhov sib txawv ntawm cov pob zeb yuav tsum muaj rau txoj kev, thiab cov pob zeb crushers thiab cov ntxaij vab tshaus siv hauv txhua qhov chaw txua txiag zeb muaj cov qauv sib txawv thiab cov lus qhia tshwj xeeb. Pob zeb nrog tib lub npe tshwj xeeb uas yuav los ntawm cov pob zeb sib txawv yuav Qhov sib txawv ntawm cov khoom sib xyaw ua rau nws nyuaj rau cov nroj tsuag sib xyaw kom tswj tau qhov sib npaug ntawm cov khoom noj thaum lub sij hawm sib tov, ua rau cov khoom seem lossis tsis txaus ntawm cov khoom siv thiab pob zeb ntawm qee yam tshwj xeeb.

3. Xaiv qhov kub rau hauv npo. Txoj kev xav, yog tias qhov gradation ntawm cov khoom kub hauv qhov chaw ruaj khov, txawm tias muaj pes tsawg lub sieve tau txhim kho, nws yuav tsis cuam tshuam qhov kev sib xyaw ntawm cov khoom sib xyaw. Txawm li cas los xij, kev tshuaj xyuas ntawm cov kub silo ntawm cov nroj tsuag sib xyaw muaj cov yam ntxwv ntawm qhov loj me me thiab tsis nthuav dav, yog li cov khoom ntawm qee qhov loj tuaj yeem sib xyaw nrog cov khoom me dua li lawv qhov loj me. Tus nqi ntawm cov ntsiab lus no feem ntau muaj kev cuam tshuam zoo rau kev xaiv qhov screen ntawm cov nroj tsuag sib xyaw thiab seb nws puas dhau lawm. Yog hais tias qhov nkhaus ntawm qhov sib tov yog du thiab qhov screen saum npoo raug xaiv kom raug, cov khoom tiav uas tsim los ntawm cov nroj tsuag sib xyaw tuaj yeem ua kom ntseeg tau tias qhov gradation tsis dhau. Txwv tsis pub, qhov tshwm sim dhau los tsis tuaj yeem zam tau thiab tej zaum yuav loj heev, ua rau cov khoom pov tseg loj thiab kev lag luam poob.

Tom qab asphalt mixing cog overflows, cov hauv qab no yuav tshwm sim:

1. Cov sib tov yog zoo graded. Nws tuaj yeem pom los ntawm cov txheej txheem kev hnyav saum toj no uas thaum lub pob zeb kub dhau mus rau hauv cov khoom sib xyaw zoo lossis cov sib sau loj, cov nplua aggregate yuav raug hnyav rau ib qho nyiaj predetermined los yog tshaj qhov ntau ntawm cov nyiaj, thaum lub loj aggregate yuav hnyav rau ib tug predetermined. tus nqi. yuav raug kaw, ua rau cov nyiaj them tsis txaus, ua rau tag nrho lossis ib nrab kev tshuaj ntsuam thinning ntawm tag nrho cov sib tov. Noj 4 kub silos ua piv txwv, kev tshuaj ntsuam ntau yam ntawm 1 #, 2 #, 3 #, thiab 4 # kub silos yog 0 ~ 3mm, 3 ~ 6mm, 6 ~ 11.2 ~ 30mm, thiab 11.2 ~ 30mm feem. Thaum silo 3 # overflows, silo 4 # thiab lwm yam. , 3 # silo yuav tshaj qhov hnyav ntau vim yog over-compensation, 4 #. Ib yam li ntawd, thaum lub 1 # warehouse overflows, 2 # warehouse overflows, thiab lwm yam., cov nyiaj them nqi ntawm 1 # warehouse ya cov khoom yuav ntau tshaj li tus nqi, thiab 2 # warehouse yuav tsis ncav cuag qhov hnyav vim tsis txaus them nyiaj. . Qhov kev teeb tsa tus nqi, qhov gradation tag nrho yog qhov zoo; Thaum lub 2 # warehouse overflows, 3 # warehouse los yog 4 # warehouse overflows, nws yuav 3 ~ 6 hli tuab thiab 6 ~ 30 hli nyias.

2. Crude sib tov. Cov sib tov ntxhib yog tshwm sim los ntawm qhov loj sieve hais tias hnyav dhau los yog cov me me sieve yog lub teeb dhau. Siv lub vijtsam ntawm cov nroj tsuag sib xyaw ua piv txwv: thaum warehouses 1 #, 2 #, 3 #, thiab 4 # overflow, lwm lub warehouses yuav hnyav. Txawm hais tias ib qho twg, ob lossis peb lub warehouses 1 #, 2 #, thiab 3 # tsis ua rau qhov hnyav ntawm cov khoom siv, cov qib tom ntej ntawm cov khoom ntxhib yuav tsum tau rov ua dua, uas yuav ua rau cov khoom loj dua, tsawg dua cov khoom me me thiab sib tov.

3. Muaj qhov sib txawv loj nyob rau hauv qhov gradation ntawm cov khoom hauv qhov sib tov. Cov dej ntws tawm hauv lub tsev sib xyaw yog vim qhov hnyav tsis txaus ntawm qee qib ntawm cov ntaub ntawv granular nyob rau hauv cov khoom kub, uas ua rau muaj ntau tshaj ntawm cov txheeb ze txaus ntawm ib lossis ntau theem ntawm cov ntaub ntawv granular, ua rau cov dej ntws tawm. Qhov sib tov ntau lawm yog tau los ntawm kev tshuaj ntsuam kub silo thiab kev sim sib xyaw. Feem ntau, tom qab lub sieve qhov ntawm lub silo kub yog txiav txim siab, qhov gradation ntawm qhov sib tov yuav tsis hloov pauv loj hauv txoj kev xav. Yam tsawg kawg ntawm qhov kev nkag mus ze ntawm lub sieve qhov ntawm lub silo kub yuav tsum nyob ruaj khov. Tshwj tsis yog tias muaj ib txoj hlua ntawm cov khib nyiab los yog lub vijtsam tawg hauv qhov kub kub, yuav muaj qhov sib txawv loj hauv cov qib sib xyaw ntawm granules. Txawm li cas los xij, hauv kev tsim kho, nws tau pom tias qhov kev sib tw ntawm qhov sib tov tsis ruaj khov tom qab xaiv qhov screen qhov.

Yuav ua li cas tswj tus nqi sib kis yog ib qho ntawm cov teeb meem tseem ceeb uas yuav tsum tau daws thaum lub sij hawm sib tov ntawm asphalt sib tov. Nws yuav tsum raug tiv thaiv los ntawm cov hauv qab no:

1. Cov khoom siv ruaj khov. Tus sau paub los ntawm ntau xyoo ntawm kev xyaum ntau lawm tias kev ruaj ntseg ntawm cov khoom siv yog tus yuam sij rau kev tswj cov dej ntws. Cov gravel tsis ruaj khov ua rau muaj qhov tsis txaus lossis ntau dhau ntawm qee qib ntawm cov khoom sib xyaw hauv cov nroj tsuag sib xyaw. Tsuas yog thaum cov khoom siv ruaj khov, cov nroj tsuag sib xyaw tuaj yeem tswj tau qhov kev sib tw ntawm qhov sib tov. Tom qab ntawd, thaum ua kom tiav qhov gradation, tus nqi ntws ntawm cov nroj tsuag sib xyaw tuaj yeem hloov kho kom sib npaug ntawm cov khoom siv txias thiab cov khoom siv kub hauv lub sijhawm luv luv. xav tau. Txwv tsis pub, qhov chaw pub khoom noj yuav tsis ruaj khov thiab nws yuav tsis tuaj yeem tswj tau ib qho kev sib npaug pub rau lub sijhawm ntev. Nws yuav siv sij hawm ib lub sij hawm ntawm kev hloov mus los ntawm ib qho kev tshuav nyiaj li cas mus rau lwm qhov, thiab qhov nyiaj tshuav tsis tuaj yeem ncav cuag lub sijhawm luv luv, ua rau muaj dej ntau dhau. Yog li ntawd, txhawm rau tswj kev nchuav, kev ruaj ntseg ntawm cov khoom siv yog qhov tseem ceeb.

2. Tsim nyog xaiv ntawm kub silo npo. Ob lub hauv paus ntsiab lus yuav tsum tau ua raws li hauv kev tshuaj ntsuam: ① Ua kom qhov sib xyaw ua kom tiav; (2) xyuas kom meej tias cov dej ntws ntawm cov nroj tsuag sib tov yog me me li sai tau.

Txhawm rau kom ntseeg tau tias kev sib xyaw ua ke ntawm qhov sib tov, kev xaiv ntawm lub vijtsam yuav tsum nyob ze li sai tau rau qhov mesh loj tswj los ntawm kev gradation, xws li 4.75mm, 2.36mm, 0.075mm, 9.5mm, 13.2mm, thiab lwm yam. tias lub vijtsam mesh ntawm cov nroj tsuag sib xyaw muaj qee qhov inclination, qhov loj ntawm qhov screen qhov yuav tsum tau nce proportionally.

Tshaj tawm ntawm kev sib xyaw cov nroj tsuag ib txwm yog ib qho teeb meem nyuaj rau kev tsim kho chav tsev kom daws tau. Thaum muaj qhov xau tshwm sim, nws yog qhov nyuaj los tswj nws kom zoo. Yog li ntawd, txhawm rau kom ntseeg tau tias muaj dej ntws tsawg npaum li qhov ua tau hauv cov nroj tsuag sib xyaw, nws yog ib qho tseem ceeb kom phim cov khoom muaj peev xwm ntawm txhua qhov kub bunker nrog nws lub peev xwm tawm. Tom qab qhov ntsuas qhov nkhaus ntawm lub hom phiaj sib xyaw yog txiav txim siab hauv chav kuaj, xaiv qhov sib xyaw cog tshuaj ntsuam xyuas yuav tsum ua raws li qhov ntsuas ntsuas ntsuas kom sib npaug ntawm cov khoom txias ntws thiab cov khoom kub xav tau ntawm cov nroj tsuag sib xyaw. Yog tias qee qib ntawm cov khoom siv granular tsis txaus, qhov loj ntawm nws lub vijtsam yuav tsum tau nthuav dav ntau li ntau tau los xyuas kom meej qhov kev thov rau cov khoom kub sib xyaw. Cov txheej txheem tshwj xeeb yog raws li hauv qab no: Faib qhov sib txawv ntawm qhov sib tov sib xyaw ua ke → Tshuaj ntsuam xyuas cov khoom siv granular → Txiav txim siab qhov mesh raws li qhov kev xa tawm → Ua kom cov proportions ntawm txhua qhov kub hauv qhov sib npaug li qhov ua tau → Txo qhov cuam tshuam ntawm cov khoom ya them nyiaj rau gradation Influence. Thaum lub sijhawm teeb tsa, sim ntsuas txhua qib ntawm cov ntaub ntawv mus rau qhov kawg. Qhov me me ntawm lub tsev khaws khoom qhov rooj kaw, qhov me dua qhov nyiaj them rau cov khoom ya; los yog ib lub tsev khaws khoom muaj ob lub qhov rooj, ib qho loj thiab ib qho me me, thiab lawv qhib thaum qhov hnyav pib. Los yog ob lub qhov rooj qhib tib lub sijhawm, thiab tsuas yog lub qhov rooj me me qhib thaum kawg ntawm qhov hnyav kom txo tau qhov cuam tshuam ntawm cov khoom siv ya los ntawm kev muab qhab nia thaum kawg ntawm qhov hnyav.

3. Txhim khu kev taw qhia kev xeem. Lub chaw soj nstuam yuav tsum tau nce qhov zaus ntawm kev soj ntsuam cov ntaub ntawv raw raws li qhov ntau ntawm cov ntaub ntawv raw nkag mus rau hauv qhov chaw thiab hloov cov ntaub ntawv raw, ua kom ntws curves ntawm txias silos ntawm lub sij hawm, thiab pub ntau yam ntaub ntawv rov qab mus rau qhov sib tov cog nyob rau hauv lub sij hawm. kev coj noj coj ua kom raug thiab raws sijhawm, thiab tswj xyuas cov xwm txheej kub thiab txias sib npaug ntawm cov khoom sib npaug.

4. Kev txhim kho ntawm asphalt sib tov khoom sib xyaw. (1) Teem ntau lub thoob dej ntws ntawm cov nroj tsuag sib xyaw, thiab teeb tsa lub thoob thoob rau txhua qhov khoom kub kub los tiv thaiv cov dej ntws los ntawm kev sib xyaw thiab ua rau nws nyuaj rau rov siv dua; (2) Ua kom cov nyiaj ya raws cov nyiaj them rau ntawm kev tswj vaj huam sib luag ntawm cov khoom sib xyaw nrog cov khoom siv thiab kev debugging, cov nroj tsuag sib xyaw tuaj yeem kho cov khoom ya ya raws cov nyiaj tsis hais seb nws puas dhau los lossis tsis, kom cov khoom sib tov tuaj yeem tswj tau. ruaj khov gradation nyob rau hauv qhov txwv.
