Aluminum stationary moving floor for bunker integration

STATIONARY MOVING FLOOR

Design and manufacture of an integral aluminum platform with a semi-stanchion type moving floor for mounting inside the bunker type structure with support at two ends.
Description of the platform:
1. 1. Double T-beams in 450 mm aluminum AL6005 T6 extruded in one piece without welding of 14.000 mm.
  2. 80 mm asymmetrical double T-beams in AL6082 T6.
  3. ALITE 140 mm AL6082 T6 aluminum extrusion tube sash.
  4. Double T 450 mm AL6005 T6 double T cross members.
  5. Two (2) support benches with four (4) integral aluminum legs for each support. Front bedplate with integrated swivel system. Adjustable telescopic type rear bedplate. Load cells mounted between the support plates and the legs of the bedplates provided by the customer.

Telescopic rear support system with hydraulic drive by means of a hydropneumatics pump with manual and pneumatic drive to adjust the rear part to the height of the hopper and to be able to replace the blades in the event of maintenance.
Maximum capacity of the equipment 26 Tn of load at 250 bars.
ALITE Heavy-Duty moving floor machine adapted to a width of 3,000 mm. Bolted assembly on the frame beams and integrated into the platform belts.
Twenty-six (26) slats 112 mm wide and 8 mm thick + 1.5 mm shoulder in AL6082 T6. Semi-stanch type moving floor slats with integrated fluid collection rails. Forged aluminum tips screwed at both ends to allow the blades to be removed for maintenance and/or replacement.
Integral aluminum leachate collection tank at the rear of the load, with removable access manholes on both sides for cleaning and maintenance. Built-in ball-type unloading and emptying tap.
Externally powered 24 VDC control panel with connector for cable control and/or connection to the plant control console. 24 VDC 10 A power supply at the customer’s expense. Emergency manual override integrated in the control cartridges of the moving floor machine.
Un-anodized raw aluminum finish.
Hinged lifting eye system for safe and centered lifting for positioning of the platform inside the factory hopper with crane.

1. 1. Maximum power 50 hp (37 kW).
  2. Maximum continuous pressure 240 bar.
  3. Adjustable flow rate 0-90 l/min.
  4. Driven by asynchronous motor and frequency inverter.
  5. Integral open type aluminum base with adjustable support legs. Upper roof made of folded aluminum sheet, checkerboard 3/5 mm.

Siemens motor 50 HP (1.500 rpm) IE3 4P 380/660 B3 group 225S with B5 flange + additional forced ventilation kit group 225s for continuous operation at low frequencies with maximum torque.
Direct coupling for B5 flange d60 shaft with motor key with ISO 7653 flange + ISO14 DIN 5462 shafts for pump.
Fixed displacement pump 51 cm3/rev, PARKER F1-51 plus axial piston pump, angled or similar.
Vector type frequency inverter for high torque DELTA/BONFIGLIOLI 37 kW 3×400 v + EMC filter 100A 400 VAC. Maximum torque regulation from 5-50 Hz.
Speed regulation by potentiometer on panel, current input on the frequency inverter for external control from PLC, possibility of communication via data BUS.
