Definitions
- the invention relates to a belt conveyor for the steep and vertical conveyance of bulk material according to the preamble of claim 1.
- Such a belt conveyor can be designed as a so-called L-conveyor, which means that the conveyor run of the conveyor belt runs horizontally or slightly rising in a feed section for the bulk material and runs from a deflection device behind the feed point in a steeply increasing or vertical direction to the overhead discharge drum, wherein the back run is parallel or at least approximately parallel to the conveyor run.
- the cover assigned to the discharge drum which in the case of known belt conveyors is designed to be stationary, for example as a baffle box, is intended to prevent bulk material from spreading on the discharge drum and to ensure a somewhat ordered discharge parabola.
- the S conveyor Due to the second deflection for the conveyor section and the corresponding further deflection for the return section, the S conveyor is structurally much more complex than the L conveyor.
- the strength calculation for the conveyor belt may only refer to the edge zones of the conveyor belt. This is due to the concave deflection of the conveyor belt rear run behind the discharge drum from the horizontal to the steep or perpendicular downward direction.
- the corresponding deflection device can only act on narrow edge areas of the conveyor belt outside of its shaft edges and possibly on the head of the shaft edges, the entire tensile load of the conveyor belt on the deflection device is practically distributed only over its two edge areas, which is why a considerably higher tensile stress occurs in these than it would be the case with a uniform distribution of the tensile load over the entire width of the conveyor belt.
- the conveyor belt is to be dimensioned over its entire width for the greatest tensile stress that occurs, this results in the need for a conveyor belt whose overall load capacity is greater than would be necessary for the specified conveyor output per se.
- the invention is based on the object of providing a belt conveyor for the steep or vertical conveyance of bulk material, which is of little structural complexity in comparison to the S conveyor and without the need to use an “oversized” conveyor belt, but also at high Conveying speeds ensure an orderly, practically scatter-free delivery of bulk goods to the discharge drum.
- This object is achieved according to the invention with the belt conveyor characterized in claim 1 and with respect to advantageous configurations in the subclaims.
- the cover assigned to the discharge drum is achieved by the formation of the cover assigned to the discharge drum as a shroud that even if the conveyor belt and the return strand of the conveyor belt run vertically in front of or behind the discharge drum, an orderly, practically scatter-free bulk material discharge takes place at the discharge drum.
- This makes it possible for the first time in practice to take advantage of the structural advantages of a so-called L-conveyor for the steep and vertical conveying of bulk goods, including the particularly important advantage of being able to manage with a conveyor belt that is only dimensioned for the required conveying capacity.
- the cover band in the sense of the invention only needs to be assigned to the conveyor belt in the deflection area of the discharge drum *, ie not also in the actual conveyor section.
- a particular advantage of the belt conveyor according to the invention is further that the discharge parabola of the bulk material can be easily controlled in its course, by appropriate choice of the angle between the rear run of the conveyor belt and the run of the shroud that runs away from the deflection area. For example, slightly different conveying speeds can be taken into account depending on the grain size of the bulk material being conveyed.
- a useful structural design of the belt conveyor for controlling the ejection parabola can be seen from the claims 9 and 10.
- Figure 1 shows a section of an L-belt conveyor for vertical conveyance with the upper end of the vertical conveying lines and the moving shroud in side view;
- FIG. 2 shows a cross section along the line II-II in FIG. 1.
- the belt conveyor shown in Figure 1 for the vertical conveyance of bulk material works with a conveyor belt 1 made of rubber or the like in a conventional design, which is also equipped with two lateral shaft edges 2 which are approximately perpendicular to the conveyor belt, but also in a conventional configuration, but in Figure 1 only the one wave edge is shown schematically, that is to say without showing its waves.
- angled driver strips 5 are arranged on the conveyor belt 1 transversely to the longitudinal direction of the conveyor belt and divide the space between the shaft edges into individual conveyor spaces 6.
- it is an L-conveyor, in which the conveyor belt with its conveyor strand 1a and also with its rear strand 1b in the area of a winninggu task in a manner not shown either horizontally or slightly increasing in the conveying direction. A deflection of the conveying strand takes place behind the conveyed goods
- Conveyor belt runs in the vertical direction of an upper discharge drum 9. There it is deflected by 180 and runs as a back strand 1b also in the vertical direction away from the discharge drum 9. As a result, the bulk material is lifted in the conveying direction 8 up to the discharge drum 9 and is distributed at this at a delivery point 10.
- the discharge drum 9 is assigned a cover in the form of a moving cover band 12.
- the shroud 12 is also made of rubber or the like in a conventional design and is also provided with two lateral shaft edges 13 which also project from the shroud 12 approximately perpendicularly outwards, in FIG schematically, without showing their waves.
- the endless shroud 12 is guided by at least three shroud deflection drums 15, 16, 17 and 18 in the present exemplary embodiment.
- the shroud 12 runs on two disk wheels 25, see FIG. 2, which are arranged on both sides of the discharge drum 9 and are mounted on the same axis of rotation as this, but separately from it.
- the disc wheels engage on narrow edge areas of the shroud outside the shaft edges 13 thereof.
- the disc wheels 25 have a larger diameter than the discharge drum 9 such that de r distance of the conveyor belt 1 to the shroud 12 is greater than the height of the corrugated edges 13 of the shroud 12 and also greater than the height of the corrugated edges 2 and the driver 5 make the conveyor belt 1.
- the dimensioning of the shroud is such that the inner distance of the corrugated edges 13 of the shroud 12 measured transversely to the shroud direction is larger than the outer distance of the corrugated edges 2 of the conveyor belt 1.
- a correspondingly deep arrangement of the shroud deflection drums 18 and 15 results in a Guiding the shroud in such a way that it converges with the conveyor run 1a of the conveyor belt at an acute angle and also runs at an acute angle to the rear run 1b or to the vertical from the deflection area of the discharge drum 9, whereby it is placed over the conveyor belt in the deflection area.
- the discharge parabola of the conveyed bulk material at the discharge point 10 arises between the vertical back strand 1b and that with a straight section from the
- Disc wheels 25 to the deflection drum 15 cover band.
- the direction of this dropping parabola can be changed in a simple manner by adjusting the position of the shroud deflection drum 15.
- it is mounted on the free end of a swivel lever 25 which can be changed in length and is swiveled about its pivot point 27 to control the discharge parabola.
- the variable-length lever 26 is constantly pressurized, for example by an internally arranged spring or by a hydraulic medium.
- the shroud has its own drive, not shown, for example by means of an electric motor. If the speed of the shroud can be adjusted via this, the discharge parabola can also be influenced by choosing a different speed of the shroud with respect to that of the conveyor belt. Alternatively, it is possible to dispense with a separate drive for the shroud and to have it carried by the conveyor belt, either by direct frictional engagement with the conveyor belt in the deflection area of the discharge drum or by coupling the disk wheels to the discharge drum.
- a row of stub rollers arranged in accordance with the path of the cover tape in the deflection area of the discharge drum can be provided, which, like the disk wheels, engage outside areas of the shaft edges 13 on edge areas of the cover tape 12.
