Description

The invention relates to material handling equipment and can be used in the transportation of various materials using steeply inclined conveyors.

A steeply inclined conveyor is known in which the transported material is held by supporting the load using transverse partitions

1.

Known steeply inclined conveyor, in

wherein the transported material is retained by increasing the pressure of the material on the load-bearing surface by means of a pressure tape or other pressure elements 2.

In these analogues, adhesion of the material to additional elements occurs, adhesion of the material to the load-bearing surface increases, which reduces the efficiency and reliability of transportation.

The closest known technical solution is the construction of a conveyor belt including tape, current collectors and electrodes connected to a constant current source 3.

The disadvantage of this conveyor is that it is not able to provide efficient transportation of wet capillary-porous materials that tend to slip on inclined sections of the conveyor track.

The purpose of the invention is to expand the functionality of a steeply inclined conveyor by providing transportation of wet materials by increasing their adhesion to a load-bearing surface.

According to the invention, in a steeply inclined conveyor, including a load-bearing surface and means for holding transported material on it, the latter are made in the form of a constant current source, a two-position dual switch, a plurality of plates mounted on a load-bearing surface with the possibility of interaction with stationary current collectors, and at least one electrode placed above the load-bearing surface with the possibility of constant contact with the transported material, while The electrode is connected to one output of the switch, and the current collectors are connected to its other output, moreover, the general view of the switch is connected to the negative pole of the DC source, and the other two inputs are connected to its positive pole.

The drawing shows the proposed conveyor, General view.

The conveyor comprises a load-bearing surface 1, on which conductive plates 2 are mounted, which cooperate with the fixedly mounted current collectors 3.

Current collectors 3 by means of current leads 4 are connected to one terminal of the switch 5, Electrodes 6 are placed above the load-bearing surface 1 with the possibility of constant contact with the transported material 7. The electrodes 6 are connected via the current leads 8 to the second terminal of the switch 5, the common input of which is connected to the negative pole of the source is 9 DC, and the other two inputs are with the positive pole of the source.

0 The conveyor works as follows.

Previously, the sign of its electrokinetic is determined for the material to be transported.

5 potential corresponding to the sign of the ions in the pores of the material, which is carried out by known methods, for example, in an electroosmotic cell.

Depending on the specific character

0 electrical potential select the appropriate position of the switch 5. So, for example, with a negative electrokinetic potential of the material 7, the DC circuit 5 closes the positive pole of the current source 9, the lead 8, electrodes 6, material 7, plates 2, current collectors 3, current lead 4 , the negative pole of the current source 9. The flow of a constant current along this circuit leads to electroosmotic dehydration of the material 7 at the surface of the plates 2, which ensures its tight adhesion to their surface and reliable fastening on a steeply inclined conveyor.

5 The current required for this is determined empirically from the conditions for providing electro-osmotic dewatering of the material at the surface of the plates, which may entail its cohesive

0 separation from the surface.

With a different sign of the electrokinetic potential of the transported material, a different position of the switch 5 is chosen, while the nature of the flow

5 physical processes are not changed in comparison with the described.

The possibility of practical implementation of this solution was tested on a conveyor with the following basic data: angle of inclination of the load-bearing surface 70 °;
