Mumigodhi yemarasha, chikurumabhandi ekutakura zvinhuMazimbe akaiswa mumigwagwa mikuru yakakombama anowanzosangana nemarasha akawandisa, anodururwa, uye anodonha panguva yekufambisa. Izvi zvinonyanya kuoneka pakutakura marasha asina kubikwa ane hunyoro hwakawanda, uko marasha anodururwa zuva nezuva anogona kusvika makumi kusvika kumazana ematani. Marasha anodururwa anofanira kucheneswa, izvo zvinokanganisa kushanda zvakanaka uye kuchengetedzeka. Kuti izvi zviitike, tangi rekuchengetera mvura rinoiswa pamusoro pebhandi rekufambisa kuti richenese marasha anodururwa. Panguva yekushanda, vharuvhu yegedhi retangi rekuchengetera mvura inovhurwa nemaoko kuti idururire marasha anoyangarara kumuswe wemuchina wekuperekedza, uko anocheneswa nemuchina wekutakurisa. Zvisinei, nekuda kwehuwandu hwakawanda hwemvura inodururwa, marasha anoyangarara akawandisa, kucheneswa kusati kwasvika nguva, uye kuva pedyo kwemarasha anoyangarara nesump, marasha anoyangarara anowanzodururirwa zvakananga musump. Nekuda kweizvozvo, sump inoda kucheneswa kamwe chete pamwedzi, zvichikonzera matambudziko akadai sekushanda zvakanyanya, kuoma kwekuchenesa sump, uye njodzi huru dzekuchengetedza.
1 Kuongororwa kweZvikonzero zveKurasa Marasha
1.1 Zvikonzero Zvikuru zveKurasikira Marasha
Chekutanga, kona yakakura yekutsvedza uye kumhanya kwakanyanya kwemuchina wekutakura zvinhu; chechipiri, nzvimbo dzisina kuenzana panzvimbo dzakawanda dziri pamutumbi wemuchina wekutakura zvinhu, zvichikonzera "bhandi richiyangarara" uye zvichikonzera kuti marasha aderere.
1.2 Matambudziko muKuchenesa Sump
Chekutanga, vharuvhu yegedhi inovhurwa nemaoko yetangi rekuchengetera mvura inowanzova nekuvhurika kwayo, zvichiita kuti mvura ibude yakawanda. Paavhareji, 800 m³ yemvura yemarasha inodururwa musump nguva imwe neimwe. Chechipiri, pasi risina kuenzana retangi gurubhandi rinotakura zvinhuMugwagwa unokonzera kuti marasha anoyangarara aunganire munzvimbo dzakaderera pasina kunyungudika panguva yakakodzera, zvichibvumira mvura kutakura marasha anoyangarara musump uye zvichikonzera kucheneswa nguva nenguva. Chechitatu, marasha anoyangarara pamuswe weconveyor haacheneswi nekukasika kana zvakakwana, zvichiita kuti anyungudike musump panguva yekusukurudza. Chechina, daro diki pakati pemuswe weconveyor huru yebhandi nesump rinobvumira mvura ine matope asina kukwana kuti ipinde musump. Chechipiri, marasha anoyangarara ane zvidimbu zvakakura, zvichiita kuti zviomere muchina wekufambisa (wakashongedzerwa nepombi yematope) kuunganidza zvinhu zvinobudirira kumberi kwesump panguva yekuchenesa sump. Izvi zvinoguma nekushanda kushoma, kupera kwakanyanya kwepombi yematope, uye zvinoda kucheneswa nemaoko kana ne loader kumberi kwesump, zvichikonzera kushanda nesimba uye kuchenesa kushoma.
2 Kugadzirwa kweSisitimu Yekurapa Marasha Yakakwana Yekudonhedza Marasha Yemabhandi
2.1 Kutsvaga neKuyera Chirongwa
(1) Kunyange zvazvo kona yekutsvedza kwebhandi isingachinjike, kumhanya kwayo kunogona kugadziriswa zvichienderana nehuwandu hwemarasha. Mhinduro yacho inosanganisira kuisa chikero chebhandi panzvimbo yekudyisa kuti iongorore huwandu hwemarasha uye kupa mhinduro chaiyo kune system yekudzora. Izvi zvinobvumira kugadzirisa kumhanya kwekushanda kwebhandi guru kuti kuderedze kumhanya uye kuderedza kudonha kwemarasha.
(2) Kuti tigadzirise nyaya yekuti "bhandi rinoyangarara" rinokonzerwa nenzvimbo dzisina kuenzana panzvimbo dzakawanda dziri padivi pemuviri wemuchina wekutakura zvinhu, matanho anosanganisira kugadzirisa muviri wemuchina wekutakura zvinhu nemugwagwa kuti bhandi rifambe zvakanaka. Pamusoro pezvo, michina yepressure roller inoiswa kuti igadzirise dambudziko rekuti "bhandi rinoyangarara" uye kuderedza kudonha kwemarasha.
2.2 Sisitimu Yekuchenesa Yega Pamucheto Wekumashure Uchishandisa Loader
(1) Chidzitiro chinotenderera uye chidzitiro chinotenderera chinotenderera chinokwira kumusoro kwebhandi. Chidzitiro chinotenderera chinounganidza uye chinoisa marasha akadururwa muzvikamu otomatiki. Chinhu chisina kukura chinosukwa nemvura kuita muchina wekuchenesa, nepo chinhu chikuru chinoendeswa kuchidzitiro chinotenderera chinotenderera chinotenderera. Kuburikidza nebhandi rinotenderera, chinhu chinodzoserwa kumudziyo mukuru.bhandi rinotakura zvinhuChinhu chisina kukura chakabva pachiratidziro chinodedera nemhepo chinoyerera negiravhiti kuenda kuchinochenesa sump chemhando yescraper.
(2) Mvura inoyerera negravity ichienda kumuchina wekukweva, uko zvidimbu zvakakura kupfuura 0.5 mm zvinoburitswa zvakananga pamuchina wekutakura mabhandi. Mvura inoyerera kubva mumuchina wekukweva, inoyerera negravity ichipinda mutangi remvura.
(3) Njanji nechikwidzo chemagetsi zvakaiswa pamusoro petangi remvura. Pombi yemvura inorema inomanikidzwa ine simba ine kuvhunduka inoiswa mukati metangi remvura inoputika uye inofamba ichidzokera shure nekudzoka kuti inotakura mvura yakagara pasi kuenda kumashini yekuchenesa ine simba. Mushure mekusefa nemashini yekuchenesa ine simba, keke remarasha rinoburitswa pabhandi rekufambisa, ukuwo mvura inotsvedza ichiyerera negiravhiti ichipinda musump.
2.3 Zvinhu zviri muComprehensive Coal Spillage Treatment System
(1) Sisitimu iyi inodzora otomatiki kumhanya kwekushanda kwebhandi guru kuti ideredze kudonha kwemarasha uye kugadzirisa nyaya ye "bhandi rinoyangarara". Inodzora nehungwaru vharuvhu yegedhi retangi rekuchengetera mvura, ichideredza huwandu hwemvura inoyerera. Kuiswa kwemaplate epolyethylene ane huremu hwakawanda kwazvo pasi pemugwagwa kunoderedza huwandu hwemvura inoyerera inodiwa. Huwandu hwemvura inoyerera pakushanda kwega kwega hunoderedzwa kusvika 200 m³, kudzikira kwe75%, zvichideredza kuoma kwekuchenesa sump uye huwandu hwemvura inoyerera mumugodhi.
(2) Chidzitiro chinotenderera chiri kumucheto wemusana chinounganidza, chinoronga, uye chinoendesa zvinhu zvacho, chichienzanisa zvidimbu zvakakura kupfuura 10 mm. Zvinhu zvisina kukura zvinoyerera negiravhiti zvichienda kumuchina wekuchenesa wemhando yescraper.
(3) Chidzitiro chinodedera chinonyungudutsa marasha, zvichideredza hunyoro hwemarasha. Izvi zvinoita kuti zvive nyore kutakurwa nebhandi guru rinotenderera uye zvinoderedza kudonha kwemarasha.
(4) Marasha anoyerera negiravhiti achipinda muchikamu chekuburitsa mvura chemhando ye scraper chiri mutangi rekugadzika. Kuburikidza nemudziyo wekugadzika weplate yemukati mehuchi. Makorasha ane makorasha akakura kupfuura 0.5 mm anoongororwa uye anoburitswa nemudziyo wekuburitsa mvura we scraper mubhandi rekuchinjisa. Mvura inoyerera kubva mumudziyo wekusuka mvura wemhando ye scraper inoyerera ichienda kutangi rekumashure re sedimentation. Mudziyo wekusuka mvura wemhando ye scraper unobata makorasha ane makorasha akakura kupfuura 0.5 mm, zvichigadzirisa matambudziko akadai sekupfekwa kwejira rekusefa uye makeke e "layered" filter mu filter press ine pressure yakakwira.
3 Mabhenefiti uye Kukosha
3.1 Mabhenefiti Ehupfumi
(1) Sisitimu iyi inobvumira kushanda pasi pevhu pasina vanhu, zvichideredza vashandi vanosvika makumi maviri uye zvichichengetedza mari inosvika mamiriyoni mana emadhora ekuAmerica pagore.
(2) Muchina wekuchenesa wemhando yescraper unoshanda wega nematanho ekutanga-kumisa eawa imwe kusvika maviri padanho rega rega uye nguva yekushanda yemaminitsi maviri chete pakushanda, zvichikonzera kushandiswa kwesimba shoma. Kana tichienzanisa nemichina yekudredha yechinyakare, unochengetedza mari yemagetsi inosvika CNY miriyoni imwe pagore.
(3) Nehurongwa uhwu, zvidimbu zvidiki chete zvinopinda musump. Izvi zvinoburitswa zvakanaka uchishandisa mapombi ane nhanho dzakawanda pasina kuvhara kana kupisa pombi, zvichideredza mari yekugadzirisa neinenge CNY miriyoni imwe pagore.
3.2 Rubatsiro Rwevanhu
Sisitimu iyi inotsiva kuchenesa nemaoko, ichideredza simba revashandi uye ichivandudza kushanda zvakanaka kwedhiriji. Nekugadzira zvidimbu zvakakora, inoderedza kupera kwepombi dzematope dzinotevera uye pombi dzematanho akawanda, ichideredza mwero wekukundikana kwepombi uye inowedzera hupenyu hwebasa radzo. Kuchenesa panguva chaiyo kunowedzera kugona kushanda kwesump, kubvisa kudiwa kwesump dzakamirira, uye kunowedzera kudzivirira mafashamo. Nekudzora kwakadzika kubva pamusoro uye kushanda pasi pevhu kusina vanhu, njodzi dzekuchengetedza dzinodzikira zvakanyanya, zvichipa mabhenefiti anoshamisa munharaunda.
4 Mhedziso
Sisitimu yakakwana yekurapa marasha akadururwa emvura hurubhandi rinotakura zvinhuiri nyore, inoshanda, yakavimbika, uye iri nyore kushandisa uye kutarisira. Kushandiswa kwayo kwakabudirira kwakagadzirisa zvinobudirira matambudziko ekuchenesa marasha akadururwa pama conveyor emabhandi makuru akakombama uye kubvisa mvura yekumashure. Sisitimu iyi haingogadzirisi kushanda zvakanaka chete asiwo inogadzirisa njodzi dzekuchengetedza pasi pevhu, zvichiratidza mukana wakakura wekusimudzira nekushandisa zvakanyanya.
