China Precoat Discharge Rotary Vacuum Drum Filter Chaw Tsim Khoom-

Precoat Discharge Rotary Vacuum Drum Filter

Lub Precoat discharge rotary vacuum drum filter yog thawj hom high-efficiency automated cais khoom nrig thiab dej cuab yeej. Nws cov tswvyaw ua haujlwm yog ua ib tug porous precoat rau saum npoo ntawm lub drum raws li cov filtration medium, tsav cov khoom filtrate los ntawm vacuum pressjoni negativ, thiab ua tiav cov kev ua haujlwm tsis tu ncua los ntawm kev sib koom mechanical discharge. Cov cuab yeej no muaj cov filtration precision siab, ruaj ua haujlwm thiab yooj yim kho, thiab tuaj yeem txo cov kev tsim khoom fais fab siv thiab cov kho cov npi thaum txhim kho cov kev tsim khoom zoo tag nrho.

Cov Yam Ntxwv ntawm Precoat Discharge Rotary Vacuum Drum Filter

1.Structural Design:Lub drum ua los ntawm ib tug integral welding lossis casting cov txuj ci, nrog cov filter qhov sib npaug faib rau saum npoo nrog ib tug anti-corrosive lining. Lub frame ua los ntawm steel structure, muaj cov ruaj zoo thiab haum rau cov hnyav haujlwm hauv cov chaw ua haujlwm.

2. Precoat System:Nws muab teeb tsa nrog ib tug precoat sib xyaw tank, metering pump thiab distributor, uas tuaj yeem tswj cov precoat tuab raug thiab kom cov filtrate ua haujlwm ib yam.

3. Vacuum System:Nws siv scraper lossis hlua discharge hom, nrog cov scraper lub kauj ruam adjustable, pub tag nrho peeling ntawm cov filter cake yam tsis muaj residue thiab zoo zam cov khoom poob.

4. Pov Tawm Cuab Yeej:Nws siv scraper lossis hlua discharge hom, nrog cov scraper lub kauj ruam adjustable, ua tiav cov tag nrho stripping ntawm cov filter cake tsis muaj residue tso tseg, zoo tiv thaiv cov khoom pov tseg.

5. Kev Ntxuav Haujlwm:Ib tug spray kev ntxuav system muab los ua countercurrent kev ntxuav ntawm cov filter cake, uas txo cov dej content ntawm cov filter cake thiab zoo txhim kho cov khoom rov qab tau.

6. Kev Nyab Xeeb Tiv Thaiv:Nws muab teeb tsa nrog overload tiv thaiv, vacuum qib abnormal alarm, automatic kua theem tswj thiab lwm cov cuab yeej, ua raws li cov kev lag luam kev nyab xeeb standards.

7. Cov Khoom Xaiv Tau:Cov khoom-contacting cov khoom xws li lub drum thiab plhoob tuaj yeem ua los ntawm 304 stainless steel, 316L stainless steel, titanium alloy, fluorine-lined khoom, thiab lwm yam, kom haum rau cov sib txawv corrosive media.

Txoj Kev Ua Haujlwm ntawm Precoat Discharge Rotary Vacuum Drum Filter

Cov filter siv ib tug precoat raws li cov high-precision filtration medium. Cais khoom nrig thiab dej tsav los ntawm vacuum pressjoni negativ, thiab ib tug closed-loop txuj ci ntawm regeneration-filtration-ntxuav-pov tawm ua tiav los ntawm cov kev lis lis ntawm lub drum, pub cov kho zoo ntawm cov fine-grained thiab nyuaj-rau-filtrate cov khoom.

Cov kauj ruam tshwj xeeb yog raws li no:

1. Precoat Formation:Cov precoat khoom xws li diatomite thiab perlite sib xyaw nrog dej kom ua ib tug suspension, uas raug adsorbed rau saum npoo ntawm lub drum nyob rau hauv pressjoni negativ kom tsim ib tug porous filtration sab nrog ib tug tuab ntawm 0.5–5 mm. Qhov sab no tiv thaiv lub drum thiab txhim kho cov filtration precision.

2. Pressjoni Negativ Filtration:Lub drum lis me ntsis thiab immersed mus rau hauv cov khoom. Vacuum pressjoni negativ tsav cov filtrate hla cov precoat thiab cov filter qhov ntawm lub drum, thaum cov khoom nrig particles raug ntes kom ua ib tug filter cake.

3. Filter Cake Kev Ntxuav:Tom qab lub drum lis tawm ntawm cov khoom thaj chaw, cov spray cuab yeej spray cov ntxuav kua. Nyob rau hauv cov hauj lwm ntawm pressjoni negativ, cov tshuav valuable components hauv cov filter cake raug ntxuav tawm thiab cov dej content txo qis.

4. Mechanical Pov Tawm:Ib tug scraper lossis hlua-hom cuab yeej siv los scrape tawm ob qho cov filter cake thiab cov invalidated saum npoo precoat sab, kom tsis muaj residue nyob rau hauv lub drum saum npoo.

5. Circulation Regeneration:Cov pov tawm drum rov qab adsorbs tshiab precoat suspension kom ua ib tug tshiab filtration sab, pib lwm lub filtration sij hawm thiab pub cov kev ua haujlwm tsis tu ncua.
