Reconstruction vim li cas
Lub limestone crushing system yog tsim los ntawm BZ2000 × 10000 lub luag haujlwm hnyavapron feeder muagthiab PF2018 ib leeg -theem rauj crusher, nrog rau tsim muaj peev xwm ntawm 500t, tab sis qhov tseeb muaj peev xwm yog tsawg dua 400t, thiab limestone crushing zog noj yog siab. Tom qab ntawm - qhov chaw soj ntsuam, lub limestone crushing system tau hloov kho, thiab cov zis tau nce mus rau ntau dua 460t / h, uas ua tiav lub hom phiaj ntawm kev hloov kho.
I. Phenomena
(1) Los ntawm kev soj ntsuam, nws pom tias lub kaum sab xis ntawm lub apron feeder rau muag yog loj (23 degree), thiab cov ntaub ntawv nyob rau hauv lub zawj phaj plam thaum lub sij hawm ua hauj lwm, thiab lub thickness ntawm cov khoom txheej yuav ua tsis tau raws li qhov yuav tsum tau tsim.
(2) Vim tias cov limestone feem ntau yog thauj mus rau hauv cov nroj tsuag los ntawm cov mines me me, vim qhov sib txawv ntawm qhov sib txawv ntawm cov limestone rau hauv cov nroj tsuag ntawm txhua lub mine, cov av impurities yog loj, thiab qee cov tawv roob yog sib xyaw ntawm cov mines, uas ua rau muaj kev hloov pauv loj hauv lub tshuab crushing.
(3) Vim lub sijhawm ua haujlwm ntev thiab cov khoom tsim tawm tsawg, txhawm rau kom ntseeg tau tias cov khoom xav tau, lub sijhawm poob thiab kev saib xyuas tsis txaus, thiab qee zaum kev tsim khoom qeeb vim kev saib xyuas.
Ii. Txoj kev hloov pauv
(1)Apron feeder muagmechanical part technical reform
Txhawm rau txhim kho lub thickness ntawm cov ntaub ntawv txheej thiab txo qhov tshwm sim ntawm cov khoom zawv zawg, weld ib tug 80 hli dav steel phaj ( ntsug welding) nyob rau thaum xaus ntawm lub conveyor trough phaj ntawm lub phaj feeder, thiab weld ib thooj txhua peb bins los txhim kho qhov tob ntawm lub hopper rau muag thiab nce cov khoom nqa peev xwm ntawm Apron feeder rau muag. Ua kom lub thickness ntawm cov khoom txheej.
(2) Kev txhim kho cov khoom siv hluav taws xob ntawm phaj feeder
Lub phaj feeder kho qhov ceev ceev los ntawm kev hloov pauv zaus. Lub inverter txais Schneider series. Lub zog ntsuas ntawm lub inverter yog 45kW thiab qhov ntsuas zaus yog 50Hz. Tom qab kuaj xyuas tias lub zog ntawm lub cev muaj zog thiab cov reducer tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev nce zaus, cov txheej txheem ntawm zaus hloov pauv tau hloov kho, qhov zaus ntawm zaus hloov pauv hloov los ntawm yav dhau los 50Hz mus rau 60Hz, thiab cov ntsuas tam sim no ntawm zaus hloov pauv hloov mus rau qhov ntsuas tam sim no ntawm lub cev muaj zog 94A.
(3) Alate feeder tiv thaiv transformation.
Tom qab qhov kev hloov pauv parameter, qhov kev kuaj load tau ua tiav. Raws li qhov ntsuas qhov siab tshaj plaws load tam sim no, muab faib los ntawm qhov kev ntseeg tau ntawm 1.2, tus nqi tiv thaiv tam sim no ntawm inverter yog qhov zoo ntxiv. Los ntawm yav dhau los 94A, hloov mus rau 63A, kom ntseeg tau tias muaj kev ntseeg siab thiab rhiab heev ntawm kev tiv thaiv inverter.
(4) Crusher tiv thaiv transformation
Txhawm rau tiv thaiv cov dej xau hauv lub crusher tom qab qhov zaus hloov pauv ceev nce, ua rau txoj siv peb sab ntawm lub crusher slipping thiab hlawv kev huam yuaj, siv cov khoom siv tiv thaiv kab mob yog ntsia ntawm txoj siv rubey ntawm lub crusher. Thaum lub crusher pulley ceev yog tsawg rau 70% ntawm qhov ntsuas ceev, ncaj qha dhia lub crusher thiab phaj feeder.
(5) Hloov hom kev pub mis ntawm lub phaj feeder
Kev pub noj ntawm thawj phaj feeder yog tus Tsov tus tw, thiab nws tau hloov mus rau hauv ob sab pub, uas yog qhov tsim nyog rau kev txhim kho lub thickness ntawm lub phaj feeder.
Thib peb, cov txiaj ntsig ntawm kev hloov kho tshiab
Tom qab cov kev hloov pauv saum toj no thiab 3 lub hlis ntawm kev ua haujlwm tsis tu ncua, kev nyab xeeb thiab du, apron feeder rau muag tau ua tiav cov txiaj ntsig zoo. Cov ntsuas kev siv hluav taws xob tau poob qis, kev siv hluav taws xob tau raug txo los ntawm thawj 2.5kWh / t mus rau 1.8kWh / t, cov khoom tsim tawm ntawm lub tshuab crushing tau nce los ntawm qhov qub tsawg dua 400t / h mus rau ntau tshaj 500t / h, thiab lub peev xwm ntau lawm tau siv tag nrho.
