Zida Zinayi Zoyambira Zazida za Electrostatic Spray Systems

kwambiri ufa wophimba Machitidwe opopera a electrostatic ali ndi zida zinayi zofunika - hopper feed, electrostatic powder spray gun, electrostatic power source, and powder recovery unit. Kukambitsirana kwa chidutswa chilichonse, kuyanjana kwake ndi zigawo zina, ndi masitayelo osiyanasiyana omwe alipo ndikofunikira kuti timvetsetse momwe ntchitoyi ikuyendera.

Ufa umaperekedwa kumfuti yopopera kuchokera pagawo loperekera ufa. Nthawi zambiri zinthu za ufa zomwe zimasungidwa m'gawoli zimathiridwa madzi kapena kudyetsedwa ku chipangizo chopopera kuti zinyamulidwe kupita kumfuti yautsi (Chithunzi 5-9). Njira zatsopano zopangira chakudya zimatha kupopera ufa molunjika kuchokera mubokosi losungirako.

Chipangizo chopopera nthawi zambiri chimagwira ntchito ngati venturi, pomwe mpweya woponderezedwa kapena wokakamizidwa umadutsa pampu, kupanga siphoning zotsatira ndi kujambula ufa kuchokera ku feed hopper kupita ku mapaipi a ufa kapena machubu odyetsa, monga momwe tawonetsera pa Chithunzi 5-10. Mpweya ndi jiniralAmagwiritsidwa ntchito kulekanitsa tinthu tating'ono ting'onoting'ono kuti tithe kunyamula ndi kulipiritsa mosavuta. Voliyumu ndi liwiro la kutuluka kwa ufa zitha kusinthidwa.

Nthawi zambiri, chipangizo cha feeder chimagwiritsa ntchito mpweya, kugwedezeka, kapena makina osonkhezera kuti athandize "kuswa" ufa. Kuchita izi kumapangitsa kuti ufa ukhale wosavuta, pomwe umathandizira kuwongolera kuchuluka ndi kuthamanga kwa ufa kupita ku mfuti zopopera. Kuwongolera kodziyimira pawokha kwa kuchuluka kwa ufa ndi mpweya kumathandizira kupeza makulidwe ofunikira a zokutira. The ufa wodyetsa amatha kupereka zinthu zokwanira kwa mmodzi kapena angapo electrostatic kutsitsi mfuti several mapazi kutali. Zodyetsa ufa zimapezeka m'miyeso yambiri yosiyana, ndi kusankha malingana ndi ntchito, kuchuluka kwa mfuti zomwe ziyenera kuperekedwa, ndi kuchuluka kwa ufa wothiridwa mu nthawi yodziwika. Generalwopangidwa ndi chitsulo chachitsulo, gawo la feeder litha kukhazikitsidwa moyandikana, kapena kukhala chophatikizika.ral gawo la, kuchira unit.

Magawo a feeder, omwe amagwiritsa ntchito mpweya wotulutsa madzi kuti athandizire kupopera zinthu za ufa kumalingaliro opopera. Mpweya woponderezedwa, kapena wokakamizidwa, umaperekedwa ku jini ya air plenumralili pansi pa gawo la feeder. Pakati pa mpweya plenum ndi thupi lalikulu la wodyetsa unit ndi nembanemba, nthawi zambiri wopangidwa ndi porous pulasitiki-composite zakuthupi. Mpweya woponderezedwa umadutsa mkati mwake ndi kulowa mkati mwa gawo lalikulu la chakudya, momwe zinthu za ufa zimasungidwa. Kuchita kwa madzi kwa mpweya kumabweretsa kukweza zinthu za ufa m'mwamba, kupanga dziko losokonezeka, kapena lamadzimadzi (Chithunzi 5-2). Ndi zochita za fluidizing izi, ndizotheka kulamulira metering wa ufa siphoned kuchokera feeder unit ndi Ufumuyo, kapena pansi pamadzi, venturi-mapope chipangizo (onani Chithunzi 5-9).

Mukamagwiritsa ntchito magawo a chakudya chamtundu wa mphamvu yokoka, opareshoniyi imaphatikizapo kagawo kakang'ono kamene kamasungidwa ndi ufa. Zipangizo zopopera zomwe zimalumikizidwa ndi mtundu uwu wa feeder nthawi zambiri zimakhala za pampu yamtundu wa venturi. Nthawi zina, kugwedera kapena makina osonkhezera amagwiritsidwa ntchito kupititsa patsogolo kupopera kwa ufa ndi mphamvu ya venturi yopangidwa ndi chipangizo chopopera. Ufa ndi mphamvu yokoka imadyetsedwa ku zipangizo zopopera, ndipo kutulutsa madzi kwa ufa sikofunikira. Onaninso Chithunzi 5-9. Ufa ukhozanso kuperekedwa mwachindunji kuchokera ku mabokosi a ufa kapena zitsulo zogwiritsira ntchito chubu cha siphon chopangidwa bwino, chomwe chimapereka madzi okwanira am'deralo kuti alole kutumiza yunifolomu.

Zipangizo zosefera nthawi zina zimagwiritsidwa ntchito limodzi ndi ma feeder unit kuti awonetse zinyalala zilizonse, ufa wochuluka, ndi zinyalala zina, ndikuyika ufa usanapopere. Sieve izi zitha kuyikidwa mwachindunji kapena pamwamba pa gawo lodyetsa kuti ufa usavutike munjira yotsekeka ya ufa, kupopera ndi kuchira (Chithunzi 5-1 1).
