ʻO ka ʻōnaehana hoʻoheheʻe ʻana i ka ea he ʻano kiʻekiʻe loa o ke ʻano hoʻoili pneumatic airtight, e hoʻohana ana i ka ea haʻahaʻa haʻahaʻa e hele ai i nā lole paheʻe ea e hoʻokō i ke kumu o ka lawe ʻana i ka pauka/particles.
Hoʻopuehu ka ea compresses ma hope o ka hele ʻana i ka lole paheʻe ea a komo a puni nā ʻāpana, e lanakila ana i ke kūʻē ʻana o nā ʻāpana a me nā lole paheʻe ea, no laila e lilo nā ʻāpana i nā kūlana fluidization e like me ka wai, a laila kahe e ka umekaumaha i loko o ka pahu.
Ke hoʻohālikelike ʻia me kekahi mau ʻōnaehana hoʻoili mechanical, ʻo ka ʻōnaehana hoʻoheheʻe ea me nā waiwai o nā ʻāpana ʻole, ʻaʻohe walaʻau, ka hana maʻalahi a me ka hoʻokele ʻana, ke kaumaha o nā mea hana māmā, ka hoʻohana haʻahaʻa haʻahaʻa, ka hana maʻalahi, ka hiki ke lawe nui, a maʻalahi ke hoʻololi i ke ala lawe. . ʻO nā lako waiwai maikaʻi loa no ka lawe ʻana i nā mea pauda a me nā mea paʻa nui.

1.Construction a me ka hoʻolālā
1.1, kūkulu
ʻO ka pahu paheʻe o ka ea ke ʻano maʻamau i ka mokulele ākea, a ua hoʻolālā ʻia ka ʻāpana me ka huinaha.
Hoʻohui ʻia ka chute ea me ka chute luna a me ka chute haʻahaʻa, nā lole paheʻe ea i hoʻokomo ʻia i waenakonu e hana i ka ea paheʻe chute me nā keʻena ʻelua, ka mea pauka e kahe ana i loko o ke keʻena luna i kapa ʻia ʻo ke keʻena mea a me ka ea paʻa i lalo. keena i kapaia ke keena ea.
E kānana ʻia ka ea i hoʻopaʻa ʻia a hoʻoneʻe ʻia i kekahi kaomi e like me ka noi ʻana, a laila e komo i loko o ka lumi ea ma o ka paipu ea, a laila e komo i loko o ke keʻena mea ma o nā lole paheʻe ea.
ʻO ka holo ʻana o ka ea i loko o nā lole paheʻe ea a hoʻopaneʻe i ka mea pauka e lilo i ke kūlana fluidized, e hoʻololi i ke kihi friction o ka mea pauda a me ka hoʻopili ʻole ʻana i ka mea me nā lole paheʻe ea. Eia nō naʻe, wikiwiki ka holo o ka mea, akā liʻiliʻi loa ke kūpaʻa frictional me nā lole paheʻe ea.
ʻO ka hope loa, e hoʻokuʻu ʻia ka ea paʻa i hui pū ʻia me ka mea pauka i ka lewa ma o ka kānana, a kahe ka mea pauda ma ke awa hoʻokuʻu o ka ea slide chute.
ʻO nā mea i kūkulu ʻia o ka ea paheʻe chute no ke koho ʻana he kila kalapona, alumini alumini, kila kila a i ʻole nā ​​mea metala.
Hiki ke hana ʻia nā lole paheʻe ea i nā mea like ʻole, e like me ka pulupulu, polyester, aramid, a hiki i ke aniani fiber, basalt a pēlā aku. I kekahi manawa hiki ke hoʻolālā ʻia me nā microplates, e like me nā papa seramika porous, nā papa plastik porous sintered a pēlā aku.

1.2, hoʻolālā a me ka helu ʻana.
ʻO nā mea koʻikoʻi o ka hoʻolālā a me ka helu ʻana o ka ʻōnaehana hoʻokele air slide chute ʻo ia ka nui o ke keʻa o ka chute, ka mamao o ka lawe ʻana, ke kihi inclination, ke kaomi ea, ka hoʻohana ʻana i ka ea, a me ka hiki ke lawe.
I mea e hiki ai i ka mea ke lawe maʻamau a paʻa i ka ea paheʻe chute, ʻo ke ʻano pono e pono ai ka ea me kahi kaomi a lawa ka kahe kahe.
1.2.1, hoʻolālā kaomi ea
ʻO ke kaomi ea e pili ana i ke kū'ē o nā lole paheʻe ea a me ke kiʻekiʻe o ka mea i lawe ʻia i loko o ke keʻena mea pauda.
Pono nā lole paheʻe ea me ke kūpaʻa kūpono e hōʻoia i ka hāʻawi like ʻana o ka ea i loko o ke keʻena mea.
Hiki ke hoʻoholo ʻia ke kaomi ea ma ke ʻano penei:
P=P1+P2+P3

ʻO ka P1 ke kū'ē i nā lole paheʻe ea, ʻo KPa ka ʻāpana;
ʻO ka P2 ke kū'ē i nā mea pauda, ​​ʻo KPa ka wae;
ʻO P3 ke kū'ē o nā laina paipu.
Wahi a nā ʻike, koho mau ka ea paʻi P ma waena o 3.5 ~ 6.0KPa, i ka wā e hoʻolālā ai, ʻo ka hapa nui e like me 5.0KPa.

ʻO ka lole hoʻoheheʻe ea he ʻāpana koʻikoʻi o ka ʻōnaehana hoʻoheheʻe ea / pneumatic conveying chute, ʻo ke koho kūpono o ka lole paheʻe ea ʻo ia ka precondition o ka hana kūpono o ka ʻōnaehana hoʻokele air slide chute.
Pono nā lole paheʻe ea me ka ʻaoʻao pore, ka hāʻawi like ʻana o ke ʻano ulana, maikaʻi ka ea permeability, a ʻo ka nui o ka pore e ʻoi aku ka liʻiliʻi ma mua o ke anawaena o nā ʻāpana o ka mea pauka e lawe ʻia e pale i nā lole paheʻe ea. .
Ma lalo o nā kūlana hoʻokele paʻa, ʻoi aku ka nui o ka pale ʻana o ka ea / ka hāʻule ʻana o ke kaomi ma luna o nā lole paheʻe o ka ea ma mua o ka pale ʻana o ka ea / kaomi kaomi ma luna o ka mea pauka e lawe ʻia ana, a ʻo ka hāʻule ʻana o ke kaomi ma luna o nā lole paheʻe ea e ʻaʻahu, a i ʻole ka ea. Hiki ke ālai ʻia ka ʻōnaehana hoʻoheheʻe slide chute ma muli o ka pilikia o nā lole paheʻe ea, no laila e ʻoi aku ka kiʻekiʻe o ka hoʻololi ʻana.

ʻO nā lole hoʻoheheʻe ea mai Zonel Filtech, hōʻoia mākou i ka hana maikaʻi ma 12month ma hope o ka hoʻokomo ʻana a i ʻole 18month ma hope o ka hoʻopuka ʻana, akā i ka wā e hana pololei ai, inā maikaʻi ke kūlana hana, hiki i ka hana maikaʻi o nā lole paheʻe ea mai Zonel Filtech ke kū ʻoi aku ma mua o 4 mau makahiki, hiki ke mālama i ka nui o ka mālama ʻana a me ka manawa no kā mākou mea kūʻai aku.

1.2.2, ka nui o ka hoohana ana i ka ea.
ʻO ka nui o ka hoʻohana ʻana i ka ea i hoʻopaʻa ʻia no ka ʻōnaehana hoʻoheheʻe ea e pili ana i kēia mau mea:
ʻO nā waiwai kino o ka mea, ka nui o ke keʻa a me ka lōʻihi o ka launder, ke kiʻekiʻe o ka papa lepo lepo, ke ʻano o ka launder, etc.
I mea e pale aku ai i ka pale ʻia ʻana o nā lole paheʻe ea, pono e hoʻoheheʻe ʻia ka ea i hoʻolako ʻia a hoʻopau ʻia.
Hiki ke helu ʻia ka hoʻohana ʻana i ka ea o ka ʻōnaehana hoʻoheheʻe ea/pneumatic conveying chute e kēia ʻano:
Q=qWL

ʻO "q" ka ea permeability o ka lole paheʻe ea, ʻo ka ʻāpana he m3 / m2.h, e like me ka "q" maʻamau mākou e koho 100 ~ 200;
ʻO W ka laula o ka pahu kahe mea pauda;
ʻO L ka lōʻihi o ke kahe kahe o ka pauda.

1.2.3, ka mana o ka ʻōnaehana hoʻoheheʻe ea
Ua hoʻokō ʻia ka mana o ka ʻōnaehana hoʻokele air slide chute e nā kumu he nui, hiki ke ʻano ke ʻano penei:
G=3600 X S.ρ.V = 3600 X Whρ.V

ʻO S ka ʻāpana ʻāpana o ka mea pauda i loko o ka pahu paheʻe ea, ʻo ka hui ʻana he m2;
ʻO P ka mānoanoa ea o ka mea i hoʻoheheʻe ʻia, ʻo ka ʻāpana kg/m3;
ʻO V ka mea pauda e kahe ana ka māmā, ʻo ka ʻāpana m/s;
ʻO ka W ka laula o loko o ka pahu paheʻe ea;
ʻO H ke kiʻekiʻe i loko o ka pahu paheʻe ea.

Wahi a ka loina o ka mechanics wai, ʻo ke kahe ʻana o nā mea pauka i loko o ka chute paheʻe ea e like loa me ke kahe mālie o ka wai i loko o ke kahawai ākea, no laila e pili ana ka wikiwiki o ka mea pauka i ke ʻano o ka ea slide chute. e like me ka laula o ka ea pahee chute a me ka mana mea kiʻekiʻe i loko o ka ea pahee chute, pela:
V=C√(Ri)

ʻO C ka helu helu Chezy, C=√(8g/λ)
ʻO R ka radius hydraulic, ʻāpana m;
ʻO "i" ke ʻano o ka ʻauheʻe ea;
ʻO "λ" ka helu hoʻopili.

ʻO ka makemake o ka ea slide chute e like me ke koho maʻamau ma waena o 10% ~ 20%, ʻo ia hoʻi 6 ~ 11 degere e like me nā koi;
Inā he H ke kiʻekiʻe o ka pahu mea pauda, ​​e like me ka mea maʻamau o ka laula o ka pahu paheʻe ea W=1.5H, ʻo ke kiʻekiʻe o ka pauka h he 0.4H.

2. Ka hopena.
Hoʻohana ka ʻōnaehana hoʻoheheʻe ea / pneumatic conveying chute i ka ea haʻahaʻa haʻahaʻa no ka hoʻoheheʻe ʻana i ka mea, a hoʻohana i ka ikaika o ka mea e neʻe ai i mua. Hiki ke hoʻohana nui ʻia i ka lawe ʻana i nā ʻano like ʻole o ka ea-permeable, ka pauka maloʻo a i ʻole nā ​​​​mea granular me ka nui o ka nui ma lalo o 3 ~ 6mm.
Loaʻa iā ia nā pōmaikaʻi o ka hiki ke lawe nui, ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa, a ke hoʻonui mālie nei kāna ʻano noi.
Akā ma muli o ka hoʻokomo ʻia ʻana o ka ea slide chute, ua kaupalena ʻia ka mamao o ka lawe ʻana i ka hāʻule ʻana, ʻaʻole kūpono ia no ka lawe ʻana i luna, no laila, ʻo ka noi ʻana o ka ʻōnaehana hoʻokele air slide / pneumatic conveying chute he mau palena.
