Wherein, 1, air cushion furnace body, 2, airdraft plate, 3, centrifugal fan, 4, upper air cushion box unit, 5, lower air cushion box unit, 6, band suspension driving channel, 7, air intake passage, the 8, first return air channel, 9, the second return air channel, 10, air deflector, 11, nozzle, 12, bottom air intake passage, 13, top air intake passage, 14, fan blade.
Embodiment
For content of the present utility model is become apparent more, below in conjunction with accompanying drawing 1 and embodiment, be further described.
Fig. 1 is the structural representation of the Air Cushion Suspension generating unit of the utility model air cushion furnace, as shown in Figure 1, the Air Cushion Suspension generating unit of air cushion furnace of the present utility model, comprises air cushion furnace body 1, airdraft plate 2, centrifugal fan 3, upper air cushion box unit 4, lower air cushion box unit 5, band suspension driving channel 6, air intake passage 7, the first return air channel 8, the second return air channel 9, air deflector 10 and nozzle 11.
Air cushion furnace body 1 has inner chamber, the outside of air cushion furnace body 1 is provided with motor, 3 work of driven by motor centrifugal fan, this centrifugal fan 3 utilizes centrifugal force that gas is thrown out from peripheral direction gas from the axial suction of impeller of blower 14, the fan blade 14 of centrifugal fan 3 stretches in air cushion furnace body 1, in air cushion furnace body 1, be provided with air cushion box, the effect of this air cushion box is for drying by the upper and lower surface to band the band that suspends.At the interior fan blade 14 of air cushion furnace body 1, think that air cushion box air-supply, suspension band make the upper and lower surface of band can homogeneous heating, air cushion box, to fan blade 14 return air, has completed a wind path circulation.
In Fig. 1, air cushion box comprises a plurality of upper air cushion box unit 4 setting up and down and a plurality of lower air cushion boxes unit 5.Upper air cushion box unit 4 and lower air cushion box unit 5 all arrange separately along the delivery direction of band, the staggered both sides up and down that are distributed in the shaft centre line of fan blade 14 in upper air cushion box unit 4 and lower air cushion box unit 5, upper air cushion box unit 4 is provided with blast inlet (not shown) at top, be provided with air outlet (not shown) in bottom; Lower air cushion box unit 5 is provided with air outlet (not shown) at top, be provided with blast inlet (not shown) in bottom.Between the air outlet of the air outlet of upper air cushion box unit 4 and lower air cushion box unit 5, form band suspension Transfer pipe 6.Be symmetricly set on the nozzle 11 on air cushion box unit 4 and lower air cushion box unit 5; The air-out direction of described nozzle 11 faces band suspension Transfer pipe 6.Band is sent into band suspension Transfer pipe 6 by transport unit and is heat-treated.
