Mumigodhi yemarasha, mabhandi makuru ekutakurisa akaiswa mumigwagwa mikuru yakarerekera anowanzo sangana nemarasha kufashama, kupera, uye kudonha kwemarasha panguva yekufambisa. Izvi zvinonyanya kuoneka pakutakura marasha mambishi ane mwando wepamusoro, apo kupera kwemarasha zuva nezuva kunogona kusvika makumi kusvika kumazana ematani. Marasha akaraswa anofanira kucheneswa, izvo zvinokanganisa kushanda zvakanaka uye kuchengeteka. Kugadzirisa izvi, tangi yekuchengetera mvura inoiswa kumusoro kwebhandi rekutakura kuti ichenese marasha araswa. Panguva yekushanda, vheji yegedhi retangi rekuchengetedza mvura inovhurwa nemaoko kuti ibvise marasha anoyangarara kumuswe wemutakuri, uko anocheneswa nemutakuri. Nekudaro, nekuda kwehuwandu hukuru hwemvura inoyerera, marasha anoyangarara akawandisa, kucheneswa kusingatarisike, uye kuswedera kwemarasha anoyangarara kune sump, marasha anoyangarara anowanzo kunyururwa zvakananga musump. Nekuda kweizvozvo, sump inoda kucheneswa kamwe chete pamwedzi, zvichitungamira kune nyaya dzakadai sekuwedzera kwekushanda, kuomerwa mukuchenesa sump, uye njodzi dzakakura dzekuchengetedza.
1 Ongororo Yekuparara Kwemarasha Zvinokonzera
1.1 Zvikonzero Zvinonyanya Kuparara Kwemarasha
Kutanga, iyo hombe yekurerekera kona uye kukurumidza kwemutakuri; chechipiri, nzvimbo dzisina kuenzana pamapoinzi akawanda padivi pemuviri wekutakura, zvichiita kuti "bhandi riyerere" uye zvichikonzera kurasika kwemarasha.
1.2 Matambudziko muSump Cleaning
Chekutanga, gedhi rakavhurika nemaoko retangi rekuchengetedza mvura rinowanzo kuve nedhigirii rekuvhura risingaite, rinotungamira kumvura yakawandisa. Paavhareji, 800 m³ yemarasha slurry mvura inoputirwa mune sump nguva yega yega. Chechipiri, uriri husina kuenzana hwemugwagwa mukuru webhandi rekutakura hunoita kuti marasha anoyangarara aungane munzvimbo dzakadzika-dzika pasina sedimentation panguva, zvichiita kuti mvura itakure marasha anoyangarara kupinda musump uye zvichikonzera kuchenesa nguva nenguva. Chechitatu, marasha anoyangarara pamuswe wemutakuri haana kucheneswa nekukasira kana kunyatsocheneswa, zvichikonzera kuti apinzwe musump panguva yekutsvaira. Chechina, chinhambwe chipfupi pakati pemuswe webhandi guru rekutakura uye sump inobvumira marasha slurry mvura isina kukwana sedimentation kupinda musump. Chechishanu, marasha anoyangarara ane huwandu hwakakosha hwezvimedu zvakakura, zvichiita kuti zviome kumucheri wekufamba (akashongedzerwa nepombi yedhaka) kuunganidza zvinhu zvakanaka kumucheto wepamberi panguva yekuchenesa sump. Izvi zvinoguma nekuderera kwekushanda, kupera kwakanyanya kwepombi yedhaka, uye zvinoda kucheneswa kwemanyorero kana kurodha pamucheto wepamberi we sump, zvichitungamira kune yakanyanya kusimba kwekushanda uye kushomeka kwekuchenesa.
2 Dhizaini Yeyakakwana Marasha Spillage Kurapa System yeBelt Conveyors
2.1 Scheme Tsvagiridzo uye Matanho
(1) Nepo mawere ekurerekera ekona yebhandi inotakura haigone kuchinjwa, kumhanya kwayo kwekushanda kunogona kugadziridzwa zvichienderana nehuwandu hwemarasha. Mhinduro yacho inosanganisira kuisa chiyero chebhanhire panzvimbo yekudyisa kutarisa vhoriyamu yemarasha uye kupa chaiyo-nguva mhinduro kune control system. Izvi zvinobvumira kugadzirisa kumhanya kwekushanda kweiyo huru bhandi conveyor kuderedza kukurumidza uye kuderedza kurasika kwemarasha.
(2) Kugadzirisa nyaya ye "bhanhire rinoyangarara" rinokonzerwa nenzvimbo dzisina kuenzana pamapoinzi akawanda padivi pemuviri wekutakura, matanho anosanganisira kugadzirisa ese ari maviri muviri wekutakura uye nzira yemugwagwa kuti bhandi rifambe munzira yakatwasuka. Pamusoro pezvo, midziyo yekumanikidza inoiswa kuti igadzirise "bhandi rinoyangarara" nyaya uye kuderedza kurasika kwemarasha.
2.2 Otomatiki Yekuchenesa Sisitimu paMuswe Kupera Uchishandisa Rodha
(1) Roller screen uye high-frequency vibrating screen inoiswa kumucheto wemuswe webhandi rekutakura. Iyo roller skrini inounganidza uye inoisa mumapoka marasha akadeuka. Iyo undersized material inoputirwa nemvura kune scraper-type sump cleaner, nepo iyo yakawandisa zvinhu inoendeswa kune yakakwira-frequency vibrating skrini. Kuburikidza nekufambisa bhandi rekutakura, izvo zvinotumirwa kumashure kune huru bhandi conveyor. Iyo undersized material kubva pahigh-frequency vibrating screen inoyerera negiravhiti kune scraper-type sump cleaner.
(2) Mvura yemarasha inoyerera inoyerera negiravhiti kuenda kune scraper-mhando sump cleaner, uko zvidimbu zvakakora zvakakura kupfuura 0.5 mm zvinoburitswa zvakananga pamutakuri webhandi. Mvura inopfachukira kubva kune scraper-type sump cleaner inoyerera negiravhiti ichipinda mutangi re sedimentation.
(3) Chinjanji uye chikwiriso chemagetsi zvakaiswa pamusoro petangi rekuchera. Pombi inorema-inomanikidzirwa yesludge ine kubvongodza inoiswa mukati metangi rekunyungudutsa uye inofamba ichienda mberi nekudzoka kutakura matope akagadzika kuzasi kune high-pressure filter press. Mushure mekusefa ne-high-pressure filter press, keke remarasha rinorasirwa pane yekufambisa bhandi rekutakura, nepo mvura yekusefa ichiyerera negiravhiti ichipinda musump.
2.3 Zvimiro zveComprehensive Coal Spillage Treatment System
(1) Iyo sisitimu inongodzora kumhanya kwekushanda kwebhandi guru rekutakura kuderedza kurasika kwemarasha uye kugadzirisa "bhandi rinoyangarara" nyaya. Inodzora zvine hungwaru gedhi revhavha yetangi rekuchengetedza mvura, ichidzikisa huwandu hwemvura inoyerera. Kuiswa kwe-ultra-high molecular weight polyethylene plates panzira yemugwagwa kunowedzera kudzikisira kudiwa kwemvura inoyerera. Huwandu hwemvura yekugezesa pakushanda hwakadzikiswa kusvika pa200 m³, kudzikira ne75%, zvichidzikisa kunetsa kwekuchenesa sump uye kuwanda kwemvura yemugodhi.
(2) Chidzitiro che roller kumucheto wemuswe chinounganidza, kurongedza, uye kuendesa zvinhu, kugadzika zvimedu zvakakura kupfuura 10 mm. Iyo undersized material inoyerera negiravhiti kune scraper-type sump cleaner.
(3) Iyo yepamusoro-frequency vibrating skrini inopedza marasha, ichidzikisa hunyoro hwemazimbe emarasha. Izvi zvinoita kuti zvifambiso zvifambe pamukwidza webhandi guru uye zvinoderedza kurasika kwemarasha.
(4) Coal slurry inoyerera negiravhiti mukati me scraper-type discharge unit mukati mekugadzirisa tangi. Kuburikidza nemuzinga wayo wemukati wehuchi inclined plate yekugadzika mudziyo. Mazimbe emarasha akakura kupfuura 0.5 mm anoiswa giredhi uye anoburitswa kuburikidza ne scraper discharge mudziyo pane inotakurisa bhandi rekutakura. Mvura inofashukira kubva kune scraper-type sump cleaner inoyerera ichienda kuseri sedimentation tank. Iyo scraper-type sump cleaner inobata zvidimbu zvemarasha zvakakura kupfuura 0.5 mm, kugadzirisa nyaya dzakadai sekupfeka jira remasefa uye "layered" sefa makeke mu-high-pressure filter press.
3 Kubatsira uye Kukosha
3.1 Mabhenefiti Ehupfumi
(1) Iyo sisitimu inogonesa kushanda pasina munhu pasi pevhu, kuderedza vashandi nevanhu makumi maviri uye kuchengetedza ingangoita CNY 4 miriyoni mumitengo yegore yebasa.
(2) Iyo scraper-type sump cleaner inoshanda pakarepo nekutanga-kumira kutenderera kwemaawa 1-2 pamutambo uye nguva yekumhanya yemaminetsi maviri chete pakushanda, zvichiita kuti simba rive shoma. Kuenzaniswa neyechinyakare dredging midziyo, inochengetedza ingangoita CNY 1 miriyoni mumitengo yemagetsi pagore.
(3) Nehurongwa uhu, zvimedu zvakanaka chete zvinopinda musump. Izvi zvinokwenenzverwa kunze uchishandisa mapombi akawanda pasina kuvharika kana kupera kwepombi, zvichidzikisa mutengo wekugadzirisa neanenge miriyoni imwe yeCNY pagore.
3.2 Zvakanakira Zvemagariro
Iyo sisitimu inotsiva kucheneswa kwemanyorero, kudzikisa kuwanda kwevashandi nekuvandudza dredging kunyatsoita. Nekufanogadzirisa zvimedu zvakakasharara, zvinoderedza kusakara uye kubvaruka pamapombi ematope anotevera uye pombi dzematanho akawanda, kudzikisa huwandu hwekutadza kwepombi uye kuwedzera hupenyu hwavo hwesevhisi. Kuchenesa-chaiyo-nguva kunowedzera simba rinoshanda re sump, kunobvisa kudiwa kwema sumps ekumira, uye kunosimudzira kuramba mafashama. Nekutonga kwepakati kubva pamusoro uye zvisina kurongwa zvepasi pevhu, njodzi dzekuchengetedza dzakadzikiswa zvakanyanya, zvichiunza mabhenefiti anoshamisa munharaunda.
4 Mhedziso
Iyo yakazara marasha spillage kurapwa sisitimu yeiyo huru bhandi conveyor iri nyore, inoshanda, yakavimbika, uye iri nyore kushandisa uye kubata. Kushanda kwayo kwakabudirira kwakanyatso kugadzirisa matambudziko ekuchenesa kurashikirwa kwemarasha pane akatenuka akarerekera mabhandi makuru ekutakurisa uye kudhiza iyo yekumashure sump. Iyo sisitimu haingonatsiridza mashandiro ekushanda chete asiwo inogadzirisa njodzi dzekuchengetedza pasi pevhu, zvichiratidza kugona kukuru kwekusimudzira nekushandisa.
