Description: Top sealing cover assembly for corn starch production vibrating screen equipment, upper housing sealing spare for screening units. Seals over uppermost sieve frame; sealing gasket sits between dust cover and sieve frame and secured via quick release latches. Fully encloses screening working chamber to stop starch dust fugitive emission polluting workshop atmosphere, while also preventing external contaminants falling into product stream.
Lid body: Round stainless steel shallow cover, slightly domed at centre for improved structural strength.
Inlet nozzle: Top central short pipe connecting with upstream feed pipe.
Sight glass: Side mounted viewing window for observing internal screening and feed conditions.
Quick release latches: Circumferential latches clamping lid firmly onto sieve frame top edge.
Sealing gasket: Gasket fitted beneath lid rim sealing against upper surface of sieve frame.
Optional vent port: Top exhaust nozzle for dust collection pipeline connection.
Reinforcing ribs: Internal stiffener ribs resisting vibration caused deformation.
Realises combined sealing and dust containment functions.
1. Enclosed screening chamber: Dust cover sits atop uppermost sieve frame, fully enclosing internal screening working volume.
2. Leak tight sealing: Lid rim gasket presses firmly onto sieve frame upper edge, preventing dust escape through assembly gaps during screen vibration.
3. In situ process monitoring: Side sight glass enables real time internal process inspection without opening cover assembly.
4. Quick access maintenance: Release quick release latches to lift off lid for screen mesh swap out or internal cleaning.
5. Exhaust dust removal: Optional vent port interfaces with dust extraction pipeline to evacuate dust laden air from screening chamber.
Dust tight sealing performance: Gasket plus quick release latch combination eliminates fugitive dust spillage and preserves clean workshop environment.
Food grade material: 304 stainless steel, polished inner surfaces satisfying food hygiene specifications.
Built in visual inspection: Side window enables persistent running status monitoring.
Fast open close architecture: Latches permit rapid lid removal for screen mesh replacement.
Fully removable for thorough sanitisation and disinfection.
Corrosion resistant stainless steel construction, tolerates starch dust ambient conditions.
Reinforced mechanical design: Anti deformation performance under sustained cyclic vibration.
