Kiln Technology | Iimbangela eziNgxamiseko zokuSilela kunye nokuJonga iNgxaki kwi-Rotary Kiln(1)

1. Izitena ezibomvu eziwayo
Unobangela:
(1) Xa ulusu lweziko elijikelezayo lungaxhonywanga kakuhle.
(2) I-cylinder ishushu kwaye ikhubazekile, kwaye udonga lwangaphakathi alulingani.
(3) I-oven lining ayikho kumgangatho ophezulu okanye ayitshintshwa ngexesha elifanelekileyo emva kokuba ibhityile.
(4) Umgca osembindini wombhobho we-rotary kiln awuthe tye; ibhanti levili kunye nephedi zigugile kakhulu, kwaye i-radial deformation ye-cylinder iyanda xa i-gap inkulu kakhulu.

Indlela yokulungisa ingxaki:
(1) Umsebenzi we-batching kunye nokusebenza kwe-calcination unokuqiniswa.
(2) Lawula ngokungqongqo umsantsa phakathi kwebhanti yevili kunye nephedi kufutshane nendawo yokudubula. Xa i-gap inkulu kakhulu, i-pad kufuneka itshintshwe ngexesha okanye ilungiswe ngeepads. Ukuze uthintele kwaye unciphise ukunxiba okubangelwa ukuhamba kwexesha elide phakathi kweepads, i-lubricant kufuneka yongezwe phakathi kwebhanti yevili kunye ne-pad.
(3) Qinisekisa ukuba i-oven imisiwe xa isebenza, kwaye ulungise okanye ubeke indawo ye-cylinder ye-rotary kiln kunye ne-deformation egqithisileyo ngexesha;
(4) Lungiselela rhoqo umgca ophakathi we-cylinder kwaye ulungelelanise indawo yevili elixhasayo;
(5) Khetha izibane ezikwizinga eliphezulu, phucula umgangatho wokufakwa kweziko, lawula ngokungqongqo umjikelo wokusetyenziswa kwezibane, jonga ukutyeba kwezitena kwangethuba, kwaye ubeke endaweni yezibane ezigugileyo ngexesha.

2. I-shaft yevili elixhasayo yaphukile
Oonobangela:
(1) Ukudibanisa phakathi kwevili elixhasayo kunye ne-shaft akunangqiqo. Ukuphazamiseka phakathi kwevili elixhasayo kunye ne-shaft ngokuqhelekileyo yi-0.6 ukuya kwi-1/1000 ye-shaft diameter ukuqinisekisa ukuba ivili elixhasayo kunye ne-shaft ayiyi kukhululeka. Nangona kunjalo, oku kuphazamiseka kuya kubangela ukuba i-shaft icuthe ekupheleni komngxuma wevili oxhasayo, okukhokelela ekugxininiseni uxinzelelo. Akunzima ukucinga ukuba i-shaft iya kuphuka apha, kwaye oku kunjalo.
(2) Ukudinwa ukuphuka. Ngenxa yoxinzelelo olunzima lwevili elixhasayo, ukuba ivili elixhasayo kunye ne-shaft zibhekwa njengento yonke, ukunyanzeliswa kokugoba kunye noxinzelelo lwe-shear ye-shaft yizona zikhulu kakhulu kwinxalenye ehambelanayo yokuphela komngxuma oxhasayo. Le nxalenye ilungele ukukhathala phantsi kwesenzo sokutshintshana kwemithwalo, ngoko ke ukuphuka kufuneka kwakhona kwenzeke ekupheleni komdibaniso phakathi kwevili elixhasayo kunye ne-shaft.
(3) Iziphene zokwenziwa kokwenziwa kwe-roller shaft ngokubanzi kufuneka yenziwe, yenziwe ngoomatshini, kunye nobushushu buphathwe ngee-ingots zentsimbi okanye intsimbi engqukuva. Emva kokuba iziphene zenzeke phakathi kwaye azibonakali, ezifana nokungcola kwi-ingot yensimbi, ukubunjwa kwesikhumba sezinambuzane, njl., kunye neentanda ezincinci zivela ngexesha lonyango lokushisa. Ezi ziphene azigcini nje ukukhawulela amandla okuthwala i-shaft, kodwa zibangela uxinzelelo loxinzelelo. Njengomthombo, xa uqhekeko lusanda, ukuphuka akunakuphepheka.
(4) Uxinzelelo lweqondo lokushisa okanye amandla angafanelekanga Ukufudumeza kwethayile enkulu ye-rotary kiln yimpazamo eqhelekileyo. Ukuba ukusebenza kunye nokugcinwa kungafanelekanga, kulula ukubangela ukuqhekeka kwendawo kwi-roller shaft. Xa i-tile enkulu itshisa, ukushisa kwe-shaft kufuneka kube phezulu kakhulu. Ngeli xesha, ukuba i-shaft ipholile ngokukhawuleza, ngenxa yokupholisa okucothayo kwangaphakathi kwe-shaft, umphezulu we-shaft ocutheka ngokukhawuleza unokukhulula kuphela uxinzelelo olukhulu lokucutheka ngeentanda. Ngeli xesha, ukuqhekeka komphezulu kuya kuvelisa uxinzelelo loxinzelelo. Ngaphantsi kwesenzo sokutshintshana koxinzelelo, xa i-crack isanda ngokujikeleza kwaye ifikelela kwinqanaba elithile, iya kuphuka. Kukwanjalo nangamandla agqithisileyo kwi-roller. Ngokomzekelo, ukulungiswa okungafanelekanga kubangela amandla amaninzi kwi-shaft okanye icandelo elithile le-shaft, ekulula ukubangela ukuphuka kwe-roller shaft.

Indlela yokukhupha:
(1) Izixa ezahlukeneyo zokuphazamiseka zisetyenziswa kwivili elixhasayo kunye nommandla wokufakwa kwe-shaft. Ngenxa yokuba isixa sokuphazamiseka phakathi kwevili elixhasayo kunye ne-shaft likhulu, i-shaft iya kuncipha kule ndawo emva kokuphela komngxuma wangaphakathi wevili elixhasayo lishushu, lipholile kwaye liqinisiwe, kwaye uxinzelelo lwexinzelelo lukhulu kakhulu. Ngoko ke, ngexesha loyilo, ukuveliswa kunye nenkqubo yokufakela, isixa sokuphazamiseka kweziphelo ezimbini zomngxuma wangaphakathi wevili elixhasayo (uluhlu malunga ne-100mm) luyancipha ngokuthe ngcembe ukusuka ngaphakathi ukuya ngaphandle ukuze kuncitshiswe ukwenzeka kwentamo. Isixa sokunciphisa sinokuncitshiswa ngokuthe ngcembe ukuya kwisinye kwisithathu ukuya kwisiqingatha semali yokuphazamiseka okuphakathi, ukwenzela ukuba ugweme okanye unciphise i-necking phenomenon.
(2) Ukufunyaniswa kweziphoso ezibanzi ukuphelisa iziphene. Iziphene ziya kunciphisa amandla okuthwala i-shaft kwaye kubangele uxinzelelo lwexinzelelo, oluhlala lubangela iingozi zokuphuka. Umonakalo mkhulu kwaye kufuneka uthathwe ngokungathí sina. Kwi-shaft yevili elixhasayo, iziphene kufuneka zifunyanwe kwangaphambili. Ngokomzekelo, ngaphambi kokucubungula, ukhetho lwezinto eziphathekayo kufuneka luhlolwe kwaye akukho zixhobo zengxaki kufuneka zikhethwe; ukufunyaniswa kwesiphene kufuneka kwakhona kuqhutywe ngexesha lokucubungula ukuphelisa iziphene, ukuqinisekisa umgangatho wangaphakathi we-shaft, kwaye ngexesha elifanayo uqinisekise ukuchaneka kokulungiswa kwe-shaft, kunye nokuphelisa imithombo yokuqhekeka kunye nemithombo yoxininiso loxinzelelo.
(3) Ukulungelelaniswa okunengqiqo kwe-kiln ukunciphisa imithwalo eyongezelelweyo. Ii-shafts ezininzi ze-roller zixhasa ubunzima obupheleleyo be-oven ngokusebenzisa ii-roller. Umthwalo mkhulu kakhulu. Ukuba ukufakela okanye ukulungiswa kokulungiswa kungafanelekanga, umthwalo we-eccentric uya kwenzeka. Xa umgama osuka kumgca ophakathi kweziko ungahambelani, i-roller ethile iya kuba phantsi kwamandla amaninzi; xa i-axis ye-roller ingahambelani nomgca ophakathi we-kiln, amandla kwelinye icala le-shaft liya kwanda. Amandla agqithisileyo angafanelekanga aya kubangela ukuba ukuthwala okukhulu kushushu, kwaye kuya kubangela umonakalo kwi-shaft ngenxa yoxinzelelo olukhulu kwindawo ethile ye-shaft. Ngoko ke, ukugcinwa kunye nokulungelelaniswa kwe-kiln kufuneka kuthathwe ngokungathí sina ukuphepha okanye ukunciphisa imithwalo eyongezelelweyo kwaye wenze i-kiln iqhube lula. Ngethuba lenkqubo yokulondoloza, gwema ukuqala umlilo kunye ne-welding kwi-shaft, kwaye ugweme ukugaya i-shaft ngevili lokugaya ukunciphisa umonakalo kwi-shaft.
(4) Musa ukupholisa i-shaft eshushu ngokukhawuleza ngexesha lokusebenza. Ngethuba lokusebenza kwe-kiln, ukuthwala okukhulu kuya kubangela ukufudumeza ngenxa yezizathu ezithile. Ngeli xesha, ukuze kuncitshiswe ilahleko yemveliso, ezinye iiyunithi zihlala zithatha ukupholisa ngokukhawuleza, okulula ukubangela iintanda ezincinci kumphezulu we-shaft, ngoko ke ukupholisa okucothayo kufuneka kwamkelwe ukuphepha ukupholisa ngokukhawuleza.
