    The invention relates to conveyor transport, in particular to methods of transporting material with fines by a conveyor belt in conditions where some of the fines, for example coal, remain after unloading onto the surface of the belt. As a result, requests are formed under the conveyor belt, the belt and rollers get dirty, as a result of which they wear out faster. A known method of transporting material with a small belt conveyor includes: Putting calcium chloride solution onto a tape before loading, followed by loading it with material and delivering it to a discharge drum 1. This method is used mainly in freezing conditions on the tape to reduce freezing little things. The closest in technical essence and achievable effect to the proposed is a method of transporting material with a trifle belt conveyor, including spraying onto the tape in front of the loading unit a silicone emulsion followed by loading the material onto it and moving them to the unloading end of the conveyor with the last unloading 2. This method is mainly intended for use in the conditions of freezing on the conveyor belt fines and does not effectively reduce the adhesion of the material on the tapes. y The purpose of the invention is to reduce sticking of fines to the conveyed material on the conveyor belt. This goal is achieved by the fact that according to the method of transporting material with a trifle belt conveyor, including spraying onto the tape in front of the loading unit silicone emulsion followed by overloading the material onto it and moving them with tape to the discharge end of the conveyor followed by unloading, use water as a silicone emulsion silicone emulsion with a concentration of 0.15-0.50 wt.%. FIG. 1 shows the conveyor and the arrangement of the zlo; in fig. 2 shows a solution sprayed onto a belt; ya fig. 3 is a block diagram of a mechanism for spraying pacv solution. The transport method is intended primarily for use under the condition of a coal mine to move the coal from the place of delivery to a place remote from it. Conveyor 1 includes a closed conveyor belt 2, which is located between the head bar. tank 3, located at the head end 4 of the conveyor, and tail drum 5, located at the tail end 6, where the loading conveyor yiracTOK is located. Under the upper branch 7 of the tape, supporting rollers 8 are installed, which serve as a support for the tape between the reels. The rollers 8 not only support the belt, but also provide support for the material being moved 9. The rollers 11 are located under the lower branch 10 of the belt. The material is loaded at the tail end of the conveyor with the help of a loading device 12. The material and the belt begin to move to go. good end. At the head end, the load is dropped from the belt when it changes direction around drum 3 and starts moving in the opposite direction to drum 5. During reverse movement, fines, such as coal, which adhered to the belt or were partially pressed into it during transport: , it is torn down and discharged under the belt and onto the supporting rollers 11. To prevent accumulation of small things on and under the belt, as well as on the supporting rollers, a spraying mechanism 13 and a cleaning mechanism 14 are installed. The cleaning mechanism can be any known and employed in the art of the conveyor and spraying mechanism is schematically illustrated in FIG. 3. The spray mechanism applies a coating of an aqueous solution of an aqueous emulsion of an organic silicon compound onto the carrier material side, tape. The spray mechanism includes an emulsion sector 15, a water sector 16, and a nozzle sector 17. The emulsion sector 15 includes a source or reservoir 18 of an aqueous silicone emulsion and a metering pump 19, which pumps the emulsion into a device where it is dissolved with water. The water sector 16 of the spray mechanism includes a screen filter 20 located between the pressure regulator 21 and the source 22 of water. The emulsion sector and the water sector function through a liquid solenoid 23, which is driven by an electric controller 24 that determines the solsoid switch on frequency. The regulator 24 is connected to an 110 V AC source to turn the solenoid on and off at a predetermined frequency. A solenoid for a fluid is charged by pumping an aqueous solution of an aqueous emulsion to the nozzles 17 of the spraying mechanism, the latter containing a plurality of nozzles and a conduit 25 connecting each nozzle to the liquid solenoid. The concentration of the emulsion in its aqueous solution pumped to the nozzles through a liquid solenoid is determined by adjusting the dosing pump, the pressure regulator or Tm, and others together. The number of spray nozzles required for coating depends on a number of parameters. FIG. Figure 2 shows the main factors affecting the coating. Tape 2, having a width A, a number of nozzles B with small openings, usually in the range of 0.043-0.13 cm, located one from another at a distance D and from the tape at a distance C, is a case where the correct application The thief is a complicated process. It is also necessary to determine the exact concentration of the emulsion in water. A highly viscous aqueous silicone emulsion compound has shown the most effective. This is an HV-490 emulsion (manufactured by Dow Corning Corporation, Midland, Mich.) Made from dimethyl polysiloxane fluid, having a relatively high viscosity. The emulsion HV-490 is manufactured at a concentration of 35% silicone fluid. Percentages of emulsion concentration are percentages of the final liquid level of the organosilicon compound in solution. Solvent-based organosilicon emulsions are unacceptable for conveyor belts under the conditions under consideration due to their damaging effect on the belt; it does not occur when using a water-based emulsion with a given concentration. Deviation from a given emulsion concentration leads to the same results as in the case when no silicone emulsion is applied, and can cause even greater accumulation of fines on the tape than in cases where no solution is applied. The organic organic compound in the range of 0.150, 20 wt.% provides a complete discharge of fine coal from both rubber and polyvinyl chloride tapes. These limits of concentrate ™ are effective for a variety of applications. Emulsion solution,. concentrations of 0.38 and even 0.5 wt.% can be successfully used in conditions of high humidity. The exact concentration of the emulsion to be applied must be determined by the specific nature of the tape, the material being transported and other factors. In particular, applying the emulsion solution at point M (Fig. 1) near the head end 4 of the conveyor provides excellent cleaning and lubrication of the support rollers. The application of the emulsion at point N (Fig. 1) near the tail end 6 of the conveyor increases the discharge of trifles at the unloading station near the head end 4 and, in addition, facilitates the transfer of the emulsion liquid and its actions to any subsequent transport device. The effectiveness of the application of the solution at points M and N or at some other point along the reverse line of the belt movement depends on the specific requirements. The type of material being transported, its properties (the tendency of the material to gather in a mass or accumulate) influence the choice of solution concentration, points and frequency of spraying solution application. mechanism. Experiments show that the concentration of the applied solution, the method and frequency of deposition or the point of application of the solution depend slightly on the inclination of the tape. The solution was applied to conveyor belts with a slope of up to 29 (in this case there was no slip of the material and rial along the belt). The application of the solution almost does not affect the sliding of the material, along with the tape. The proposed method provides improved safety in the mines, increasing the service life of the tape and reducing the cost of transportation. In addition, decreases; energy consumption, roller wear, reduced operating costs and labor input, labor.
