Abstract

The invention relates to the mining industry. The goal is to increase operational reliability and eliminate overwetting of material (M) by expanding the range of liquid flow control depending on the volume of transported M. The device contains a liquid supply pipe 1 connected to a nozzle (F) 5 having an outlet 9, a valve 6 and a sensing element in the form of a plate fixed on a horizontal shaft 10 (P) 11. One end of the P 11 is installed with the possibility of contact with M, and the other 12 is rigidly fixed on the cam 12. The latter is connected to one of the arms of the rocker arm 13 mounted on the g horizontal shaft 10. The other arm of the rocker arm 13 is connected with the thicker 17 end of the pusher 14. The free end of the latter is installed with the possibility of interaction with the valve 6 placed inside Ф 5 through the opening 9. The transported M deflects П 11 from the vertical position and through the cam 12 it acts on the shoulder of the rocker arm 13. The latter rotates on the axis 15 and raises the arm with the pusher 14, which acts on the free end of the valve 6. The fluid enters through the hole 9, is dispersed by the thickening 17 and irrigates M. Kolich The liquid increases with increasing volume M. In the absence of M, they return to the initial position P 11, the rocker 13, the pusher 14, and the valve 6 closes the water supply. 1 h. item f-ly, 1 ill.

The invention relates to the mining industry and can be used to suppress dust during loading and reloading of transported bulk materials in underground workings and on the surface.

The purpose of the invention is to increase the reliability of operation and eliminate the overwetting of the material by expanding the range of controlling the flow rate of the spray liquid, depending on the volume of the material.

The drawing shows the irrigation device loading points bulk material, General view.

The irrigation device includes a nozzle 1 for supplying a liquid, simultaneously playing the role of a housing to which a bracket 2 is attached for mounting the kinematic scheme of the device and a device 3 for mounting the device in the making. 6 to regulate the flow of fluid and, on the other hand, a fitting 7 for connecting a flexible supply hose 8. Inside the nozzle 5 there is a conical shape with a chamber in which a valve 6 is placed for adjusting All ball feed. The nozzle 5 has an outlet 9. The irrigation device contains a sensing element in the form of a plate 11 mounted on a horizontal shaft 10, the lower end of which is mounted for contact with the transported bulk material, and a cam 12 rigidly fixed at the upper end, connected through a two-arm rocker 13 to one from the ends of the pusher 14. The free end of the pusher 14 is installed with the possibility of weimode

with valve 6 for regulating the flow of fluid through the outlet 9 of the nozzle 5. The rocker 13 is fixed to the bracket 2 on the horizontal axis 15, and the arm of the rocker arm 13, connected to the pusher, is made with a larger mass than the other arm, on which the adjustable fingers 16 for interacting with the cam 12 of the plate 11. The pusher 14 at the exit of the nozzle 5 is made with a tapered thickening 17. The feed hose 8 is connected to a pumping unit (not shown) for supplying a fluid, for example water.

Irrigation device works as follows.

When approaching the overloading point, the bulk material deflects the plate 11 (the direction of the traffic flow does not play a significant role), which through the cam 12 acts on the finger 16 of the two shoulders rocker 13, pressing its shoulder downwards, while the opposite shoulder of the rocker arm rises and the pusher 14 attached to it opens valve 6 to regulate the flow of fluid.

Since the diameter of the outlet 9 of the nozzle 5 is significantly larger than the diameter of the pusher 14, water under pressure comes out of the nozzle 5 and is sprayed to form a torch of finely dispersed water. Additional dispersion of water is achieved by the collision of water particles with the cone-shaped part 17 (thickening) of the pusher 14. The more the layer of the transported material located on the conveyor belt, the more strongly the plate 11 deviates, and therefore, the pusher 14 opens the gap 6 by a large amount and the flow of water to irrigation increases. This is due to the fact that in the cell

the nozzles 5, the valve 6 for regulating the fluid supply is in contact with the cone-shaped pusher 14, whereby with a larger lift of the pusher 14 in the outlet 9 of the nozzle 5, the gap between the valve (ball) 6 and the conical part of the said chamber also increases, which leads to an increase the flow rate of the liquid from the nozzle 5. After the loading of the bulk material is completed, the plate 11 under the influence of gravity rotates on the axis 10 and occupies a vertical position, the cam 12 acts on the finger 16 and lowers the lower The end of the rocker arm 13 and the plunger 14, the valve 6 blocks the flow of water from the nozzle 5. Experimental testing showed that when the water pressure is 0.5-6 MPa, water flow is 4-8 l / min while ensuring high reliability of operation and water flow control, eliminating waterlogging of the transported material.
