Abstract
The belt conveyor arranges an air box below the loading conveyor belt of a drive pulley and a bend pulley and the air box comprises a box air chamber, an exhaust orifice plate and side supporting plates. The exhaust orifice plate is positioned at the upper part of the air chamber and is provided with a plurality of rows of air outlet openings while the conveying belt is positioned on the exhaust orifice plate and among the side supporting plates. The structure makes the conveying belt suspended on the air box under the action of an air-stream to reduce the frictional resistance, lower the dragging power and prolong the service life of the conveying belt.
Description
The utility model relates to a kind of belt conveyer, particularly a kind of belt air cushion conveyer.
Belt conveyer is the widely used transportation devices of industry such as chemical industry, coal, light industry, building materials.Belt conveyer generally all adopts drive mechanism to be loaded on cylinder on the frame, thereby driving the load-transfer device that is supported by carrying roller moves, to place mass transport on the load-transfer device to the place of appointment, for avoiding belt deflection, general side roller or the self-centering idler of adopting leads to the load-transfer device that carries, in the real-world operation, the load-transfer device that moves and the carrying roller of supporting and the carrying roller of guiding are in wipe contact, cause load-transfer device to be easy to wearing and tearing, particularly load-transfer device often easily produces deviation phenomenon, also make belt edges cause infantile failure, influence the ordinary life of load-transfer device.
The purpose of this utility model provides a kind of belt air cushion conveyer with air bellow, can reduce the wearing and tearing of load-transfer device effectively, prolongs the service life of load-transfer device.
For achieving the above object, the utility model has adopted below the load-transfer device of carrying material between the driving drum of belt conveyer and the changed course cylinder one or more air bellows has been set, air bellow is fixed on the frame to be made up of casing, air chamber, vent panel, limit supporting plate, relative with load-transfer device and be positioned on the vent panel above the air chamber many emptyings gas discharge orifice is arranged, air outlet communicates with the osed top air chamber, air chamber has an induction opening that communicates with positive pressure source, and the limit supporting plate of projection is respectively arranged in the both sides of vent panel along the load-transfer device bandwidth direction.When air chamber is sent into low-pressure air, air all can only flow out from the air outlet of vent panel, thereby is forming air film between load-transfer device and the vent panel and between both sides supporting plate and the load-transfer device.Under the effect of air film, make at the load-transfer device " suspension " that moves that carries material between the cylinder on the vent panel of air bellow.
The utility model has the advantages that: because the existence of air film, the friction between the load-transfer device of common belt conveyor and the supporting carrying roller alleviates greatly, thereby has prolonged the service life of load-transfer device; And, improve the transportation effect because the minimizing of friction drag has just correspondingly reduced power draw.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a scheme drawing of the present utility model.
Fig. 2 is the drawing in side sectional elevation of air bellow of the present utility model.
Fig. 3 is the longitudinal diagram of air bellow of the present utility model.
Driving drum 10 installs on frame of conveyer with changed course cylinder 11.By Fig. 1, Fig. 2, Fig. 3 as can be known, load-transfer device 8 is wrapped in cylinder 10, between 11, the material that is transported places on the load-transfer device 8, and this belt conveyer is that air bellow 12 is fixed on the frame, and makes load-transfer device 8 on the vent panel 5 of air bellow 12 and between the limit supporting plate 7,9.Air bellow 12 is made up of casing 1, air chamber 2, vent panel 5, limit supporting plate 7,9, work has the vent panel 5 of many row's deflation holes 4 to be positioned at the top of casing 1, and form air chamber 2 with casing, the limit supporting plate 7,9 of projection is respectively arranged in the both sides of load-transfer device 8 bandwidth direction upper air-vent plates 5.Limit supporting plate 7,9 is erected in both sides, vent panel 5 top for straight line parallel to each other, and the distance between its inboard slightly is wider than the width of load-transfer device 8.When being passed through hole 3 to leak free air chamber 2 input low-pressure airs by special pipeline, air-flow forms air film through the deflation hole 4 of vent panel 5 along flowing out between load-transfer device 8 and the vent panel 5.Air-flow is from surface 6 and gap limit supporting plate 7,9 between outflow also the form air film of load-transfer device 8 with vent panel 5 simultaneously.Formed air film makes load-transfer device 8 " suspension ".Therefore, the load-transfer device 8 that transports material does not produce direct wipe contact with air bellow, thereby has reduced resistance, has reduced power draw, and need not keep in repair substantially.
