1.1, kaho
Moea oa li-slide chute hangata o sekametse sefofaneng se tšekaletseng, 'me karolo eo hangata e entsoe ka lisekoere.
The air slide chute e kopantsoeng le chute e ka holimo le chute e ka tlase, masela a slide a moea a kentsoeng bohareng ho etsa chute ea moea e nang le likamore tse peli, thepa ea phofo e phallang ka kamoreng e ka holimo e neng e bitsa kamore ea thepa le moea o hatelitsoeng ka tlaase. phaposi e bitseng phaposi ya moya.
Moea o hatelitsoeng o tla tlhotluoa le ho hatelloa ho khatello e itseng joalo ka ha o kopuoa, ebe o kena ka kamoreng ea moea ka phala ea moea, ebe o kena ka kamoreng ea thepa ka masela a slide a moea.
The airflow feta ka masela a thellelisa moea le suspends phofo lintho tse bonahalang hore e be boemo fluidized, ho fetola khohlano angle ea lintho tse bonahalang phofo esita le ho etsa hore lintho tse bonahalang se kopane le moea slide masela. Leha ho le joalo, lebelo la ho phalla ha thepa le potlakile, empa ho hanyetsa ho ferekanngoa le masela a slide a moea ho nyenyane haholo.
Qetellong, moea o hatelitsoeng o kopantsoeng le phofo o tla tšeloa sepakapakeng ka sefe, 'me phofo e tsoe ka boema-kepe ba ho lahla moea oa slide chute.
Lisebelisoa tsa sebopeho sa li-slide chute tsa moea bakeng sa khetho e ka ba tšepe ea carbon, alloy alloy, tšepe e sa hloekang kapa lisebelisoa tse seng tsa tšepe.
Masela a li-slide a moea a ka etsoa ka lisebelisoa tse fapaneng, tse kang k'hothone, polyester, aramid, esita le khalase ea fiber, basalt joalo-joalo. Ka linako tse ling hape e ka etsoa ka li-microplates, joalo ka lipoleiti tsa porous ceramic, lipoleiti tsa polasetiki tse silafetseng joalo-joalo.

1.2, moralo le lipalo.
Likahare tsa bohlokoa tsa moralo le lipalo tsa sistimi ea phetisetso ea li-slide tsa moea li kenyelletsa boholo ba likarolo tsa chute, sebaka sa ho fetisa, sebaka sa ho sekamela, khatello ea moea, tšebeliso ea moea le matla a ho tsamaisa.
E le ho etsa hore thepa e fetisetsoe ka mokhoa o tloaelehileng le ka mokhoa o tsitsitseng moeeng oa slide chute, boemo bo hlokahalang ke hore moea o lokela ho ba le khatello e itseng le lebelo le lekaneng la ho phalla.
1.2.1, moralo oa khatello ea moea
Khatello ea moea e tlas'a khanyetso ea masela a li-slide tsa moea le bophahamo ba thepa e fetisoang ka kamoreng ea thepa ea phofo.
Masela a li-slide a moea a hloka ho ba le khanyetso e lekaneng ho netefatsa hore moea o arolelanoa ka kamoreng ea thepa ka ho lekana.
Khatello ea moea e ka khethoa ka mokhoa o latelang:
P=P1+P2+P3

P1 ke khanyetso ea masela a li-slide tsa moea, yuniti ke KPa;
P2 ke khanyetso ea thepa ea phofo, yuniti ke KPa;
P3 ke ho hanyetsa ha melapo ea liphaephe.
Ho ea ka liphihlelo, mochine oa khatiso oa moea P o lula o khetha pakeng tsa 3.5 ~ 6.0KPa, ha o etsoa, ​​​​haholo-holo ho latela 5.0KPa.

Lesela la li-slide tsa moea ke karolo ea bohlokoa ea tsamaiso ea moea ea slide chute / pneumatic conveying chute, khetho e loketseng ea lesela la li-slide tsa moea ke boemo ba pele ba ts'ebetso e phethahetseng ea tsamaiso ea moea ea slide chute.
Masela a li-slide a moea a tlameha ho ba le lehlakore la pore, kabo e tšoanang ea mokhoa oa ho loha, moea o kenang hantle, 'me boholo ba pore e lokela ho ba nyane ho feta bophara ba likaroloana tsa phofo e fetisoang ho thibela masela a slide a moea hore a thijoe. .
Tlas'a maemo a tsitsitseng a ho tsamaisa, ho hanyetsa moea / ho theoha ha khatello holim'a masela a slide a moea e lokela ho ba kholo ho feta ho hanyetsa moea / ho theoha ha khatello ho pholletsa le thepa ea phofo e fetisitsoeng, le ho theoha ha khatello holim'a masela a li-slide a moea a tlameha ho tšoana, kapa moea. slide chute convey system e ka thijoa habonolo ka lebaka la bothata ba masela a li-slide tsa moea, kahoo maqhubu a phetoho a tla ba a phahameng haholo.

Masela a slide a moea a tsoang Zonel Filtech, re netefatsa ts'ebetso e ntle ka mor'a 12month ka mor'a ho kenya kapa 18month ka mor'a ho pepa, empa ha ho sebetsa hantle, haeba boemo ba ho sebetsa bo le botle, ts'ebetso e ntle ea masela a slide a moea a tsoang Zonel Filtech a ka ema ho feta. Lilemo tse 4, tse ka bolokang litšenyehelo tse ngata tsa tlhokomelo le nako bakeng sa bareki ba rona.

1.2.2, molumo oa tšebeliso ea moea o hatelitsoeng.
Bophahamo ba tšebeliso ea moea e hatelletsoeng bakeng sa sistimi e tsamaisang li-slide chute e amana le lintlha tse latelang:
Thepa ea 'mele ea thepa, boholo ba karolo ea sefapano le bolelele ba sehlatsoa, ​​​​bophahamo ba lera la thepa ea phofo, tšekamelo ea ho hlatsoa, ​​joalo-joalo.
E le ho qoba masela a li-slide tsa moea a thibetsoe, moea o fanoeng o tlameha ho tlosoa metsi le ho tlosoa oli.
Tšebeliso ea moea ea tsamaiso ea li-slide tsa moea / pneumatic conveying chute e ka baloa ka mokhoa o latelang:
Q=qWL

"q" ke moea o kenang moeeng oa lesela la li-slide tsa moea, yuniti ke m3 / m2.h, ka tloaelo "q" re khetha 100 ~ 200;
W ke bophara ba thepa ea phofo phallo chute;
L ke bolelele ba chute ea phallo ea thepa ea phofo.

1.2.3, bokhoni ba sistimi ea phetisetso ea lilaete tsa moea
Bokhoni ba sistimi e tsamaisang li-slide chute ea moea bo entsoe ke lintlha tse ngata, foromo e ka ba e latelang:
G=3600 X S.ρ.V = 3600 X Whρ.V

S ke sebaka sa karolo ea lisebelisoa tsa phofo moeeng oa slide chute, unite ke m2;
P ke letsoalo la moea la lintho tse nang le metsi, yuniti ke kg/m3;
V ke phofo e phallang ka lebelo, yuniti ke m/s;
W ke bophara bo ka hare ba moea oa slide chute;
H ke bophahamo bo ka hare ba moea oa slide chute.

Ho ea ka molao-motheo oa mechine ea mokelikeli, phallo ea lisebelisoa tsa phofo moeeng oa slide chute e tšoana haholo le phallo e khutsitseng ea mokelikeli mocha o bulehileng, kahoo lebelo la ho phalla ha thepa ea phofo le amana le tšekamelo ea moea oa slide chute. hammoho le bophara ba slide chute ea moea le bophahamo ba lisebelisoa tsa matla moeeng oa li-slide chute, kahoo:
V=C√(Ri)

C ke Chezy coefficient, C=√(8g/λ)
R ke hydraulic radius, unit m;
"I" ke tšekamelo ea moea oa selaete chute;
"λ" ke coefficient ea likhohlano.

The tšekamelo ea moea slide chute ka tloaelo khetha pakeng tsa 10% ~ 20%, ke hore 6 ~ 11 degree ho ea ka ditlhoko;
Haeba bophahamo ba thepa ea phofo e le H, joalo ka tloaelo moea o thellang chute bophara W=1.5H, karolo ea phofo bophahamo ba h ke 0.4H.

2.Qetello.
The air slide chute conveying system / pneumatic conveying chute e sebelisa moea o nang le khatello e tlase ho nolofatsa thepa, 'me e sebelisa matla a sekametseng ho isa thepa pele. E ka sebelisoa haholo ho tsamaisa mefuta e sa tšoaneng ea lisebelisoa tsa moea, tse omeletseng kapa tse nang le granular tse nang le boholo bo ka tlaase ho 3 ~ 6mm.
E na le melemo ea matla a maholo a ho fetisa, haholo-holo tšebeliso e tlaase ea matla, 'me mefuta ea eona ea ts'ebeliso e ntse e eketseha butle-butle.
Empa ka lebaka la moea oa slide chute o kentsoeng ka mokhoa o oblique, sebaka se fetisang se lekanyelitsoe ke ho theoha, hape ha e loketse ho fetisetsa holimo, kahoo ts'ebeliso ea tsamaiso ea moea ea slide chute / pneumatic conveying chute e na le mefokolo ea eona.
