Hauv kev tsim engineering, kev xaiv ntawmmining apron feederyuav tsum xub xam lub zog tsav tsheb, txiav txim siab cov khoom siv sib kis ntawm ib qho khoom siv, thiab nrog rau kev hloov ntawm kev ua haujlwm los xam rov qab, qhov kev ua haujlwm hnyav. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tshawb nrhiav txoj hauv kev nrawm thiab raug los suav cov tsav tsheb ntawm mining apron feeder. Daim ntawv no qhia txog daim duab algorithm rau kev txiav txim siab lub zog ntawm cov khoom kub mining apron feeder.
Nyob rau hauv cov txheej txheem kev sib kis ntawm cov mining apron feeder, yuav muaj lub sijhawm hloov pauv hauv kev khiav hauj lwm ceev, uas yog, thaum cov saw txuas nkag mus rau hauv pab pawg meshing ntawm cov hniav sprocket, yuav muaj kev cuam tshuam ntau dua, thiab nws qhov cuam tshuam acceleration yog proportional rau lub square ntawm kev khiav hauj lwm ceev. Yog li ntawd, nws yog ib qho tseem ceeb heev los xaiv qhov khiav ceev ntawm no feeder tsim nyog. Yog tias qhov kev xaiv loj dhau lawm, qhov kev ntxhov siab dynamic ntawm kev sib kis yuav nce ntxiv, yog li yuav hnav thiab suab nrov. Yog tias qhov kev khiav ceev me me dhau lawm, cov khoom tsim tawm yuav raug cuam tshuam. v=0.20~0.50m/s feem ntau yog siv, yog li u=0.3m/s yog siv rau hauv qhov kev suav no. (2) Hla- ntu ntu ntawm cov khoom siv them Tus ntoo khaub lig- ntu ntu ntawm cov khoom siv them nyiaj yog nyob ntawm qhov loj me ntawm cov phaj pub noj thiab cov khoom sib dhos lub kaum sab xis. Thaum lub kaum sab xis upward inclination tsawg dua li cov khoom siv stacking lub kaum sab xis, tus ntoo khaub lig-sectional daim ntawv ntawm cov khoom siv them nyiaj yog qhia hauv daim duab 1, thiab cov qauv kev suav ntawm thaj chaw yog:
2. Lub zog tsav ntawm cov khoom kub mining apron feederRaws li lub zog graph algorithm yog: P=Fu/1000 hom P feeder tsav lub zog, kW F lub zog sprocket ncig lub zog, N feeder ruaj khov ua haujlwm, tsav sprocket circumferential quab yuam thiab kev khiav hauj lwm sib npaug, khiav qhov loj me thiab feeder conveying ntev, conveying lub kaum sab xis thiab yuav tsum tau muaj peev xwm tsim tau yam tsis muaj kev cuam tshuam, cov no, raws li kev hloov pauv ntawm cov tshuab ua haujlwm tag nrho khiav Kev tiv thaiv tuaj yeem decomposed rau hauv qhov sib npaug ntawm qhov tsis muaj -load khiav tsis kam ntawm lub feeder, kev tiv thaiv ntawm cov khoom siv thauj khoom thiab kev ua haujlwm ntawm cov khoom nqa. Peb qhov kev tiv thaiv raws li daim ntawv qhia kev ua tiav, raws li cov kev ua haujlwm tau muab tuaj yeem ncaj qha los ntawm daim duab los nrhiav cov ntaub ntawv muaj feem xyuam rau lub zog, peb summed kom tau txais tag nrho lub zog ntawm feeder, qhov no yog ib txoj hauv kev yooj yim los txiav txim siab lub zog. Thaum lub feeder phaj dav tau txiav txim siab, tus nqi ntawm 9 yog ib qho nqi, ces qhov sib npaug (6) yog kab sib npaug tsuas yog pub ntev L raws li qhov sib txawv, raws li txhua tus nqi thiab qhov sib txawv conveying ntev L tuaj yeem ua P, cov kab hluav taws xob (saib daim duab 2). Peb tsuas yog ua tsib kab hluav taws xob nrog phaj dav ntawm 400 ~ 1200mm. Raws li qhov tseeb khiav ceev ntawm lub feeder sib txawv, cov txiaj ntsig tau los ntawm daim duab 2 yuav tsum muab sib npaug ntawm (qhov tseeb khiav ceev / 0.3) kom tau txais qhov tseeb tsis muaj -load fais fab. (2) lub zog P xav tau rau cov khoom siv thauj khoom, (kW) ua ntej teeb tsa kev ua haujlwm rau kev xa cov khoom siv 100t ib teev, nrhiav kom paub lub hwj chim uas xav tau P, cov qauv kev suav yog:
Lub zog lub cev muaj zog tau txais los ntawm cov duab algorithm tuaj yeem ua tau raws li qhov xav tau tiag tiag ntawm kev tsim khoom. Txawm li cas los xij, daim duab algorithm no tsuas yog siv tau rau kab rov tav, inclined lossis kab rov tav ntxiv rau inclined tshiab cov khoom kub mining apron feeder. Rau lwm cov mining apron feeder, vim qhov sib txawv linear ceev ntawm nws cov load, Yog hais tias lub graph algorithm raug saws, lub zog nkhaus rau cov mining apron feeder yuav tsum tau kos raws li cov linear ntom ntawm cov khoom siv ntawm cov mining apron feeder nyob rau hauv daim duab hluav taws xob rau kev tsav tsheb tsis muaj -loader {3} ua ke, yog li ntawd, FIG. Nyob rau tib lub sijhawm, nws yuav tsum tau piav qhia tias kev siv cov duab kos duab yooj yim no tsis tuaj yeem tsim los rau txhua yam ntawm qhov kev sim siab ncaj ncees, yog li nws tau hais tias rau daim ntawv tshwj xeeb layout lossis kom raug xam cov feeder yuav tsum tseem siv cov kev ntsuas ntsuas.
