Description
An elevator conveyor for bulk materials 53331 has the object to provide a mechanical in particular granular and which can carry balk paths of any desired length and including vertical and horizontal paths and any combination of paths of different inclinations where the path is not at will either upwards or according to the which will be referred to herein as for is intended to replace conventional mechanical elevators such as belt or chain as well as conventional installations in which elevators and conveyors are combined since the former cannot operate in or slightly inclined the conveyors cannot operate at inclinations beyond a certain Kechaaieal are as a rule preferred to pneumatic equipment since the latter is more expensive in terms of capital investmen and operating and maintenance and requires longer interruptions of work for Bucket elevators are limited speed because of the wear of their susceptible to damage by foreign of heavy construction and conveyors are limited in speed and and similarly to and costly to operate and They also cause damage to the material being conveyors are limited in speed and in inclination open to the and the material being conveyed is apt to be scattered and also to be conveyor according to the invention eliminates the drawbacks of conventional elevator and conveyor equipment and provides advantages which will be set out The invention consists in a conveyor comprising two endless flexible belts which are guided in over at least two along a stretch between a feed point and a delivery point and are to enclose between their inner along the working the bulk material to be means along the working stretch at least along the vertical or steeply sections applying fluid pressure to the outer side of at least one of the belts so as to press the edges of the belts against each and their main parts on to the material being On the return stretch from the delivery point to the feed point the belts may along separate paths for which the required pulleys will be or together over at least part of the return but in any case they will be separated from other at the feed and delivery points by as much as is for the loading and unloading of the material to be pressure fluid may be a gas or a e use of is preferred as it is the least demanding in regard to installation and operating belts may consist of any suitable pliable material such for rubber or reinforced or or textile fabric impregnated so as to be vious to the pressure they may be so designed that they bulge more readily in the middle than at the by the preferential arrangement of reinforcing threads or wires along the For being to air each belt by run along a pneumatic box whose one open side is closed by the Or both belts may run together through g one belt along a guide member whieh the belt from yielding to ai and applying pressure to the second belt only in order to press it on to the Where a is used as the pressure analogous means will be provided for the application of the pressure to the working stretch may have a it include sections of different depending on the conditions of each particular place of For there be a first sloping or vertical ascending section for raising the material to a higher then a substantially horizontal section for conveying the material onwards at the and this may be followed by yet another sloping or vertical ascending or as demanded by local It is a great advantage provided by the invention that at the points of change inclination the material need not be transferred to another as it has generally to be in conventional The two belts simply continue on their with the material enclosed between or one of the belts continues with the and the change of inclination merely requires the provision of appropriate There is virtually no limitation to the height and length of the working The fluid pressure creates forces equal or greater the outwardly acting components of the column of material enclosed between the It follows that the fluid pressure must be the the steeper the and that no fluid pressure may sometimes be required along horizontal or gently sloping sections where the te sional forces exerted on the belte by the drive are sufficient in order to hold the belts is way of example in the accompanying drawings in 1 is a fragmentary elevation of a according to a first embodiment of the inventio and b are cross on line of of a first variant of the conveyor in the operative and 3a and b show similarly a second 4 is a fragmentary top plan partly in on of the bottom part of the conveyor of according to one variant of this elevato 5 is a fragmentary on the of a second variant thereo 6 is a fragmentary elevation of according to a second embodiment of the inventio j 7 is a elevation of the and return stretches of the belts according to yet another embodiment of the The conveyor according to the invention shown in 1 to 5 comprises two belts These are running together in a vertical working stretch between pulleys 3 and along a horizontal conveying stretch between the pulley 4 and a further pulley 5 may be the drive After the latter they separate for their return stretches on which the belt 1 is guided by idling pulleys 7 and and the belt 2 by idling pulleys Over the height of the vertical working stretch there extend two upright boxes are closed on all sides except those which are turned towards the that the box 11 o ens on to the back of belt 1 and the The joints between the free edges of each box and the respective belt are tightened in any suitable known by of resilient The has been indicated in 2 by The 12 are supplied with pressurized air through the conduits which are connected to a source of pressurized air a wind box or a In the variant according to the two belts are enclosed in a pneumatic box In this case the only joints to be tightened those at the bottom and top where the belts enter and leave the pneumatic feed point is the junction belts 1 and 2 a the pulley ed chute or spout 17 is disposed as to load the material to be conveyed on the belt 1 immediately before the belt 2 joins the spout 17 so wide in relation to the belts that the material fed to a broad middle part of the but not to their as in the belts can be reinforced at the edges and be left store yieldin i the that they can readily bulge in the while withstanding deformation at the the pulley 3 if have a hollow profile 3a as shown in whereby its outline corresponds to the fla and bulging portions of the belt 2 after the introduction of the material to be the pulley may be as shown in At the end of the horizontal conveying stretch the belts pass jointly the pulley 5 and then The As can be from the conveyor can change direction wherever this and in any height of the vertical stretch is not limited by inherent constructional features of the eonveyor and can be determined by the needs of each particular does an ascending working stretch have to be the conveying stretch between pulleys in this embodiment is may be as long as required by particular and it may slope upwards or The conveyor need not end at the pulley 5 as shown but it may continue further with any desired either upwards or The conveyor according to comprises longer belt 19 and a shorter belt The longer belt includes streteh 19a on to which the is first loaded in any suitable way in orde to be carried to the feed point at the pulley the delivery point at the pulley the belt 19 as open stretch 19b from which the be thrown off by means of a conventional tripper The belt then returns over a driving pulley 22 and three idlers 23 to the loading stretch The shorter belt runs together with the belt 19 along the vertical working stretch between the pneumatic boxes 11 and Immediately after passing the pulley 4 the belt 20 separates from the belt 19 and returns over idlers 24 to the feed point at the pulley This embodiment shows that in the conveyor according to the invention the two belts can run along different paths except along the working 7 that even on return stretch the two belts 25 and 26 run together and that they only at the feed and delivery point spout 27 enters between the two At the delivery end they together the delivery pulley and then they separate in order to discharge the for which purpose the belt 25 idles over idlers 29 and returns to the belt 26 at the idling pulley pulley 28 may be designed as the drive insufficientOCRQuality
