Zvishandiso zveSimende zveRotary Kiln

1. Zvishandiso zvesimbi zvinosimbisa faibha zvinoramba kushanda zvechitofu chesimende
Zvishandiso zvesimbi zvinosimbiswa nefaibha zvinonyanya kuisa mafiber esimbi isingatsvi kupisa muchinhu chacho, saka chinhu chacho chine simba rakawanda uye hachitsvinyi kupisa, zvichiita kuti chiwedzere kuramba kutsvinda uye hupenyu hwebasa rechinhu chacho. Chinhu ichi chinonyanya kushandiswa pazvikamu zvisingatsvinyi kupisa zvakanyanya zvakaita semuromo wekiln, muromo wekudyisa, pier isingatsvinyi kupera uye power plant boiler lining.

2. Zvishandiso zvesimbi zvisingadi simende zvechitofu chesimende
Zvigadzirwa zvinodzivirira simende zvishoma zvinoramba simende zvakanyanya zvinosanganisira zvinodzivirira simende zvine alumina yakawanda, mullite uye corundum. Izvi zvine hunhu hwesimba guru, zvinodzivirira kukwesha, zvinodzivirira kupera uye zvinoshanda zvakanaka. Panguva imwe chete, zvinhu izvi zvinogona kugadzirwa kuti zvive zvinodzivirira kuputika nekukurumidza zvichienderana nenguva yekubika yemushandisi.

3. Zvigadziko zvesimbi zvakasimba zvakasimba zvechitofu chesimende
Zvishandiso zvesimbi zvine simba guru zvinodzivirira kukurwa kwemvura zvine simba guru uye zvinodzivirira kukurwa kwemvura negasi realkaline uye tsvina, uye zvinogara kwenguva refu. Izvi zvinonyanya kushandiswa pakuvhara magonhi echoto, maovheni ekuora, masisitimu ekupisa, masisitimu ekutarisira, nezvimwewo uye mamwe machira echoto emaindasitiri.

Nzira yekuvaka simbi ine simende shoma ine aruminiyamu yakawanda yekuisa muchina we rotary kiln
Kugadzirwa kwesimbi inokanda simende ine aruminiyamu yakawanda yekuisa muchoto chinotenderera kunoda kutarisisa zvakanyanya kune zvinotevera zvishanu:

1. Kuziva majoini ekuwedzera
Zvichibva pane zvakaitika kare pakushandisa ma "castables" ane simende shoma ane aruminiyamu yakawanda, ma "expansion joints" chinhu chakakosha chinokanganisa hupenyu hwema "linings" anotenderera e "rotary kill". Ma "expansion joints" panguva yekudurura ma "linings" anotenderera e "rotary kill" anotsanangurwa seizvi:

(1) Majoini akatenderera: Zvikamu zve5m, 20mm aluminium silicate fiber felt inoiswa pakati pezvishandiso zvecastable, uye mafiber anodzvinyirirwa mushure mekuwedzera kuti adzivirire kushushikana kwekuwedzera.

(2) Majoini akati sandara: Majoini matatu ega ega echinhu chinokandwa anonamirwa neplywood yakadzika ye100mm munzira yemukati yakatenderera, uye joini inosiyiwa pamucheto wekushanda, kuti pave nemajoini matanhatu.

(3) Panguva yekudurura, mapini makumi maviri nemashanu ekuburitsa mvura anoshandiswa pa square mita imwe neimwe kuburitsa huwandu hwakati hwekuwedzera kwesimba panguva yekupedza moto muchoto.

2. Kuziva tembiricha yekuvaka
Tembiricha yakakodzera yekuvaka yemidziyo yesimbi ine simende yakaderera ine aruminiyamu yakawanda i10~30℃. Kana tembiricha yemhepo yakaderera, matanho anotevera anofanira kutorwa:

(1) Vhara nzvimbo yekuvaka yakapoteredza, wedzera nzvimbo dzekudziisa, uye dzivirira kutonhora zvakanyanya.

(2) Shandisa mvura inopisa pa35-50℃ (inobva pakuyerera kwekuyedza kwekudira panzvimbo) kuti usanganise zvinhu zvacho.

3. Kusanganisa
Sarudza huwandu hwekusanganisa panguva imwe chete zvichienderana nekugona kwemusanganiswa. Mushure mekunge huwandu hwekusanganisa hwawanikwa, wedzera zvinhu zvekukanda mubhegi pamwe chete nezvimwe zvinhu zvidiki zviri mubhegi mumusanganiswa panguva imwe chete. Tanga watanga musanganiswa kuti uome kwemaminitsi 2-3, wobva wawedzera 4/5 yemvura yayerwa kutanga, kurunga kwemaminitsi 2-3, wobva waona chikamu chimwe chete kubva muzvishanu zvemvura zvichienderana nekusimba kwevhu. Mushure mekusanganisa zvizere, kuyedza kudurura, uye huwandu hwemvura hunowedzerwa hunoonekwa pamwe chete nemamiriro ekuzunguzika uye kutsvedza. Mushure mekunge huwandu hwemvura hwawedzerwa hwaonekwa, hunofanira kudzorwa zvakanyanya. Uchitarisira kuti slurry inogona kuzunguzika, mvura shoma inofanira kuwedzerwa (huwandu hwemvura hunotarisirwa hweiyi slurry i5.5%-6.2%).

4. Kuvaka
Nguva yekuvaka simbi inokandwa nealuminium ine simende shoma inosvika maminetsi makumi matatu. Zvinhu zvakapera mvura kana zvakavharirwa hazvigone kusanganiswa nemvura uye zvinofanira kuraswa. Shandisa tsvimbo inodedera kuti idedera kuti iite slurry compact. Tsvimbo inodedera inofanira kuchengetwa kudzivirira tsvimbo inodedera kuti isashande kana tsvimbo inodedera ikakundikana.
Kugadzirwa kwezvinhu zvinokandwa kunofanirwa kuitwa muzvidimbu zvakatevedzana nechikamu cheovheni rinotenderera. Pamberi pekudurura chidimbu chega chega, nzvimbo yekuvaka inofanira kucheneswa uye hapana guruva, slag yekuwelda nezvimwe zvinhu zvakaora zvinofanira kusara. Panguva imwe chete, tarisa kana kukwesha kweanchor nependi yeasphalt pamusoro zviripo. Zvikasadaro, matanho ekugadzirisa anofanira kutorwa.
Mukuvaka chidimbu, kuvakwa kwechikamu chekukanda chidimbu kunofanira kudururwa pachena kubva kumuswe wechoto kuenda kumusoro wechoto pasi pechikamu chechoto. Rutsigiro rwetemplate runofanira kuitwa pakati pechitsigiso neplate yesimbi. Plate yesimbi nechitsigiso zvakaputirwa zvakasimba nemabhuroko ematanda. Kureba kwechimiro chekutsigira i220mm, upamhi i620mm, kureba i4-5m, uye kona yepakati i22.5°.
Kugadzirwa kwechikamu chechipiri chekukanda kunofanira kuitwa mushure mekunge chidimbu chagadziriswa uye chiumbwa chabviswa. Kune rimwe divi, template yakaita searc inoshandiswa kuvhara chigadziko kubva kumusoro wechitofu kusvika kumuswe wechitofu. Chimwe chasara chakafanana.
Kana chinhu chekukanda chazunguzika, dhaka rakasanganiswa rinofanira kuwedzerwa muchiumbwa chetai uku richizunguzika. Nguva yekuzunguzika inofanira kudzorwa kuitira kuti pasave nemabubbles akajeka pamusoro pemuviri wekukanda. Nguva yekuzunguzika inofanira kutariswa nekupisa kwenzvimbo yekuvaka. Zvakakosha kuve nechokwadi chekuti kubviswa kwedhisikaundi kwaitwa mushure mekunge chinhu chekukanda chagadziriswa uye chave nesimba rakati.

5. Kubika machira emukati
Hunhu hwekubika hwejira remuchina wekutenderera muchoto hunokanganisa zvakananga hupenyu hwebasa rejira. Munguva yekubheka yapfuura, nekuda kwekushaya ruzivo rwakakura uye nzira dzakanaka, nzira yekubaya mafuta anorema kuti apiswe yakashandiswa mukubika mukupisa kwakaderera, kwepakati nepakati uye kwekupisa kwepamusoro. Kupisa kwaive kwakaoma kudzora: kana tembiricha ichida kudzorwa pasi pe150℃, mafuta anorema haave nyore kupisa; kana tembiricha yakakwira kupfuura 150℃, kumhanya kwekupisa kunokurumidza zvakanyanya, uye kupararira kwetembiricha muchoto hakuna kuenzana. Kupisa kwejira rinopiswa mafuta anorema kwakakwira ne350~500℃, nepo tembiricha yezvimwe zvikamu yakaderera. Nenzira iyi, jira iri nyore kuputika (jira rekare rinokandwa rakaputika panguva yekubheka), zvichikanganisa hupenyu hwejira.
