Description

[0022] The invention is explained in more detail below with reference to a preferred exemplary embodiment with reference to the accompanying drawings. In the figures:

[0023] FIG. 1 is a schematic sectional illustration along a transverse direction of a conveying hose according to the invention, wherein the hose body of the conveying hose is in an intact state,

[0024] FIG. 2 is a schematic sectional illustration along a longitudinal direction of the conveying hose according to the invention, and

[0025] FIG. 3 is a further schematic sectional illustration along the transverse direction of the conveying hose according to the invention with wear phenomena occurring on the hose body of the conveying hose.

[0026] FIG. 1 shows a conveying hose 100 sectioned along a transverse direction of the conveying hose 100.

[0027] The conveying hose 100 has a hose body 10 which is rolled up to form a tube and is preferably formed from an elastic material, for example a rubber material. The hose body 10 serves to receive the material 11, for example abrasive stones, which is to be transported, wherein said material is arranged in the interior space 19 of the hose body 10, which interior space is formed by the tube shape, and is transported in said interior space. The interior space 19 is completely filled with the material 11 which is to be transported.

[0028] The hose body 10 has a plurality of layers, wherein the hose body 10 has at least one radially inner first outer layer 12, one radially outer second outer layer 18 and an inner layer 16 which is arranged between the two outer layers 12, 18. The radially inner first outer layer 12 bounds the interior space 19 and is therefore in direct contact with the material 11 being conveyed which is arranged in the interior space 19.

[0029] The conveying hose 100 further has a wear-measuring device 13. FIG. 1 shows a first electrode element 14, which is formed from a first metal material, and a second electrode element 15, which is formed from a second metal material, of the wear-measuring device 13. The two electrode elements 14, 15 are arranged in a manner embedded in the inner layer 16 of the hose body 10, so that the electrode elements 14, 15 are covered by the two outer layers 12, 18 and therefore are not visible when the hose body 10 is in an intact state, as is shown in FIG. 1.

[0030] As shown in FIG. 1, the two electrode elements 14, 15 are arranged opposite one another.

[0031] FIG. 1 shows the conveying hose in an intact state of this kind, in which no wear has yet occurred on the hose body 10 owing to the material 11 being conveyed, so that the two electrode elements 14, 15 are still completely embedded in the hose body 10 and the outer layer 12 of the hose body 10 is formed between the electrode elements 14, 15 and the material 11 being conveyed, so that contact between the electrode elements 14, 15 and the material 11 being conveyed is prevented. In this state, no current can flow between the two electrode elements 14, 15 either, so that no voltage can be detected either since the salt- and mineral-containing medium within the material 11 being conveyed cannot yet function as an ion conductor or ion bridge between the two electrode elements 14, 15 which each form a half-cell.

[0032] FIG. 2 shows a sectional illustration of the hose body 10 along its longitudinal direction and therefore along its length, wherein the section is formed through the inner layer 16 of the hose body 10. Said figure shows that the two electrode elements 14, 15 are arranged in an alternating manner, in particular in a helically alternating manner, in relation to one another, so that they form a double helix shape. The two electrode elements 14, 15 are connected to a signal unit 17 of the wear-measuring device 13, wherein this signal unit 17 forms a kind of ammeter or voltmeter. As soon as the electrode elements 14, 15 come into contact with the material 11 being conveyed and, as a result, a galvanic unit is formed, a voltage which is produced by the resulting current flow between the two electrode elements 14, 15 which occurs can be detected at the signal unit 17. As soon as a voltage has been detected at the signal unit 17, a signal, in particular a warning signal, in the form of an acoustic signal or a visual signal can be output by means of the signal unit 17, in particular by means of an output unit of the signal unit 17, in order to indicate to the operator of the conveying hose system that wear has occurred on the hose body 10 of the conveying hose 100 and appropriate measures should be taken.

[0033] As shown with reference to FIG. 2, the electrode elements 14, 15 preferably extend over the entire length of the hose body 10 and preferably also over the entire circumference of the hose body 10 in this case. The electrode elements 14, 15 can each be formed in the shape of a strip or in the shape of a wire.

[0034] The metal material of the first electrode element 14 can contain, for example, copper, preferably Cu.sup.2+/Cu. The metal material of the second electrode element 15 can contain, for example, magnesium, preferably Mg/Mg.sup.2+, or aluminum, preferably Al/Al.sup.3+, or zinc, preferably Zn/Zn.sup.2+.

[0035] FIG. 3 shows the conveying hose 100 in a state in which a large amount of wear has occurred in such a way that, on account of an abrasive action of the material 11 being conveyed, the outer layer 12 of the hose body 10 has been severely worn away at least in regions in such a way that the electrode elements 14, 15 are exposed at least in regions and therefore come into contact with the material 11 being conveyed and, in particular, the salt- and mineral-containing medium of the material 11 being conveyed. As a result, a redox reaction can start at the electrode element 14, 15 which has the more noble metal material, wherein an electrical circuit through which current can flow and, as a result, a voltage can be detected at the signal unit 17 is closed by means of the two half-cells which are formed by the electrode elements 14, 15 and contain the salt- and mineral-containing medium, which functions as the ion conductor, of the material 11 being conveyed, and the signal unit 17 which is connected to the two electrode elements 14, 15, as a result of which a signal, in particular a warning signal, can be output at the output unit of the signal unit 17 in order to be able to indicate to a user of the conveying hose system that wear has occurred on the hose body 10.
