Uri kunetseka here nemvura yakawandisa mumvura isina kuzara uye zvinhu zvakasimba mumvura yakawanda? Une chinangwa chekugadzirisa mashandiro emuchina uyu nekubvisa kuyerwa kwehuwandu hwevanhu kakawanda uye zvikanganiso zvevanhu? Vazhinji vanoshandisa muchina uyu vanosangana nematambudziko akafanana muindasitiri yekugadzira zvicherwa kuti vachengetedze mvura uye vaunganidze zvinhu zvinokosha zvekugadzirisa. Muchina uyu unoshanda zvakanaka pakuzadzisa zvinangwa izvi.
Chinyorwa chinotevera chinotarisa pakutsanangura zvinangwa nemabhenefiti ekudzora huwandu hwevanhu munzvimbo dzakasiyana dzematangi ekugocha. Ngatitangei nekutaura muchidimbu nezvemaitiro ekugocha, zvichiteverwa nezvikonzero zvishanu zvekuyera huwandu hwevanhu mukupatsanura.
Basa reKukora nderei?
Maitiro ekukora anosanganisira kupatsanurwa kwemusanganiswa wemvura yakasimba kusvika pakuyerera kwakasimba uye kuyerera kwakajeka muzvakajairika. Yekutanga ine zvidimbu zvakasimba uye yekupedzisira haibvisi kusvibiswa zvakanyanya sezvinobvira. Maitiro ekuparadzanisa ndiwo mhedzisiro yegiravhiti. Zvikamu zvese zvakakura uye zvakakora zvakasiyana zvinoumba zvidimbu zvakasiyana kuburikidza netangi.
Maitiro ekukora anoitika mutangi re sedimentation mukugadzirisa zvicherwa kuti pave nekupatsanurwa kwe concentrates ne tailings.
Nzvimbo Dzinodiwa Dzekuyera Pakukora
Mita yekuwanda kwemvura paindanetiZvinodiwa kuti zvinyatsoshanda zvakanaka zvezvikungurutsi. Semuenzaniso, nzvimbo dzekuisa dzinosanganisira nzvimbo yekudyisa, pasi pemvura, overflow uye mukati metangi rezvikungurutsitsi. Mumamiriro ezvinhu ari pamusoro apa, ma sensor aya anogona kutorwa semita yekuyera kuwanda kweslurrykanamita yekuyera kuwanda kwetsvinaDzinobatsirawo mukuvandudza kudzora otomatiki kwemadhiraivha, mapombi uye pakushandisa zvakanaka maflocculant.
Zvikonzero zvekuyera huwandu hwevanhu
Zvikonzero zvekuyera huwandu hwevanhu zvinogona kusiyana chimwe nechimwe. Mamiriro mashanu anotevera anoratidza kukosha kwekutarisa huwandu hwevanhu kuti zvikwanisike muindasitiri.
Nhamba 1 Kudzoreredza Mvura
Mvura inoonekwa seimwe yezvinhu zvakakosha zvikuru muindasitiri yemigodhi nedzezvicherwa. Saka, kudzoreredza mvura kana kushandisazve mvura kunochengetedza mari yekukora zvakanyanya. Kukura kudiki kwe1-2% muhuwandu hwemvura inoyerera zvinoreva huwandu hwakawanda hwemvura hunodiwa pakushanda. Kuwedzera kwehuwandu hwemvura kunoshanda zvakanaka mukusimbisa kusimba kwemadhamu emumvura, ayo anogona kuparara kana paine mvura yakawandisa inopombwa kuenda kumadhamu.
Nhamba 2 Kudzoserwa Kwezvicherwa
Muzvinhu zvinosimbisa ganda, chikafu chinowanzo bva muchikamu cheflotation. Kudzika kweganda kunosanganisira kupatsanura zvidimbu kuburikidza negiravhiti. Nemamwe mashoko, izvo zvine mabubble emhepo akabatana zvinokwira pamusoro uye zvinobviswa, nepo zvimwe zvichiramba zviri muchikamu chemvura. Kana izvi zvikaitika muchinhu chinosimbisa ganda, furo rinogona kutakura zvinhu zvakasimba muhuwandu hwemvura.
Zvinhu izvi zvakasimba zvinokosha uye, kana zvikasawanikwazve, zvinogona kuderedza huwandu hwese hwesimbi yakaunganidzwa. Pamusoro pezvo, zvinhu zvakaoma kana zvazara zvinogona kukonzera mitengo yakakwira ye reagent, kukuvara kwemapombi nemavharuvhu, uye kuwedzera kwemari yekugadzirisa, senge kuchenesa matangi emvura kana zvinhu zvakaoma zvikaungana ipapo.
Zvinenge 90% yezvinhu zvakasimba zvinorasika mukuwanda kwemvura zvinozopedzisira zvawanikwa muzvikamu zvekupedzisira zvemaitiro acho (semuenzaniso, mumatangi nemadhamu). Zvisinei, 10% yasara, iyo inomiririra kukosha kukuru kwehupfumi, inorasika zvachose. Kuderedza kurasikirwa kwezvinhu zvakasimba mukuwanda kwemvura kunofanira kuva chinhu chakakosha. Kuisa mari mumatekinoroji ekudzora maitiro kunogona kuwedzera mwero wekudzoreredza mvura uye kuunza purofiti nekukurumidza pakudyara.
Kushandiswa kweLonnmetermamita ehuwandu hwevanhuuyemita dzekuyereraMumvura iri pasi pemvura inoita kuti pave nekutarisa zviri nani mashandiro emuchina wekupinza. Kuonekwa kwezvinhu zvakasimba panguva chaiyo mumvura iri pamusoro pemvura kunogonawo kuitwa nekushandisa density kana solids metres. Zviratidzo zve4-20mA zvemidziyo zvinogona kubatanidzwa mu control system kuti zvikwanise kugadzirisa mashandiro acho zvakananga.
3 Kushandisa Flocculant Nemazvo
Flocculants inoshanda mukuvandudza kushanda zvakanaka kwe sedimentation, kureva makemikari anobatsira kuti zvidimbu zviri mumvura zviungane pamwe chete. Kuyera kwe flocculants kunotarisa kudzora mutengo we reagent uye kushanda zvakanaka. Density meter inobvumira density control chaiyo uye yakavimbika ye thickener feed. Chinangwa ndechekuwana percentage yepamusoro ye solids inobvira nehuremu mu feed slurry uku ichibvumira free particles settlement. Kana feed slurry density ikadarika chinangwa, process liquor inofanira kuwedzerwa, uye simba rakawanda rekusanganisa rinogona kudiwa kuti ive nechokwadi chekuti feed well inosanganiswa zvakakwana.
Kuyera huwandu hwemvura inoyerera uchishandisa mita yekudzikisa huwandu hwemvura kwakakosha pakudzora mashandiro emvura. Izvi zvinoita kuti mvura ishandiswe zvakanaka uye zvinoita kuti kusanganisa kushande zvakanaka, zvichiita kuti thickener irambe ichishanda zvakanaka.
4 Kuonekwa Pakarepo Kwematambudziko Ekukura Kweganda
Vashandi vanoedza kuchengetedza mamiriro akasimba muzviputi, vachiwana kuzara kwakajeka nemafuta mashoma uye kuzara kwakawanda nemafuta mashoma. Zvisinei, mamiriro ezvinhu anogona kuchinja nekufamba kwenguva, zvichikonzera kusagadzikana kwakashata, kudzikira kwehuwandu hwemafuta, uye kuwanda kwemafuta akaoma mumafuta akawanda. Matambudziko aya anogona kubva kumatambudziko e flocculation, mhepo kana furo mutangi, kana kuwanda kwemafuta akaoma zvakanyanya muchikafu.
Kugadzira zvishandiso uye otomatiki zvinogona kubatsira vashandisi kuchengetedza kutonga nekuona matambudziko akadaro munguva chaiyo. Kupfuura kuyerwa kwemukati, zvishandiso zvakagadzirwa nematangi zvakaita semapurobhu emubhedha ane ultrasonic zvinogona kupa ruzivo rwakakosha. Aya mapurobhu e "diver" anofamba achikwira nekudzika mukati metangi, achiongorora huwandu hwematope, nzvimbo dzekugara, uye kujeka kwemvura yakawanda. Kuyerwa kwehuwandu hwemubhedha kunonyanya kubatsira pakugadzirisa flocculation, zvichiita kuti pave nekushanda kwakafanana.
Chiyero cheKuwanda kweMadota (SDM)
Slurry Density Meter (SDM) inzira isingakuvadzi nharaunda panzvimbo pemamita emagetsi enyukireya. Yakakurumidza kuwana mukurumbira, ine mazana enzvimbo dzakaiswa pasi rese. SDM inopa zviyero zvakarurama uye zvakavimbika zvehuwandu, zvichiita kuti ive mhinduro yakanaka kune makambani emazuva ano ekugadzira zvicherwa.
Kuyera huwandu hwezvinhu kunoita basa guru mukuvandudza kushanda zvakanaka kwechinhu chinogocha uye kunoshanda sechiratidzo chikuru chekushanda kwechinhu chinogocha. Nekushandisa matekinoroji epamusoro ekuyera uye nzira dzekudzora maitiro, vashandisi vanogona kugadzirisa mashandiro echinhu chinogocha, kuwedzera mwero wekudzoreredza, uye kuderedza mari yekushandisa.
