Description

 The invention relates to pipeline transport of bulk materials, mainly crushed and finely ground rock mass, and can be used in the mining and metallurgical industry, in the construction and chemical industries, as well as in other related industries.

 A device is known for receiving slurry of rock mass for its subsequent loading into a hydrotransport pipe, including a sump for a hydraulic mixture, a suction pipe of a hydrotransport installation, and a pump. To achieve stable operation of the continuous transport installation, the drive (sump or receiver) is made with a limiter of the incoming mixture between the bottom of the tank and the suction tip of the pipeline. The limiter is made in the form of a regulating gate, increasing or decreasing the suction rate in the bore (see A.E. Smoldyrev, Hydro and pneumatic transport, M. Metallurgy, 1985, 3rd edition, pp. 211-213).

 The disadvantages of this device are: limited capacity of the drive due to the possibility of blockage of the suction pipe with any significant bunkering of the material, the impossibility of dosed supply of hydraulic mixtures as the volume of the material decreases, the mandatory maintenance of a given level of filling the tank with water and the need for manual adjustment to prevent blockages of the suction tract.

 A device is also known for accumulating, uniformly and continuously dosing a mixture of material with a working agent into a hydraulic or pneumatic transport pipeline, comprising a working agent pipeline, a storage tank with loading nozzles, a device for dumping the working agent, and a mixture-forming device for supplying the working agent to the tank having a main and auxiliary nozzles connected to the pipeline of the working agent by means of separate collectors (see the book. J. Urban. "Pneumatic ransport, "ed." Engineering ", 1967 p. 183, fig. 138).

 The disadvantage of this device is the lack of constructive study of the device in terms of devices for dumping the working agent and the unloading unit.

 The technical result achieved by the invention is to achieve a stable process for the accumulation, uniform and continuous dosing of a mixture of material with a working agent in the pipeline of hydraulic and pneumatic transport.

 This technical result is achieved due to the fact that in the known device for the accumulation, uniform and continuous dosing of a mixture of material with a working agent in a hydraulic or pneumatic transport pipeline, the device for dumping the working agent is made in the storage tank above the loading nozzle, holes for dumping the working agent and filters installed in the area of these holes, and the loading nozzle is equipped with a flow divider hermetically connected to it, and the main the second nozzle is made movable along the vertical axis of the discharge pipe with the ability to control the distance between them.

 In addition, the fact that the loading nozzle of the device is equipped with shields attached to the storage tank, auxiliary nozzles are located on the bottom surface of the storage tank in a checkerboard pattern and at an angle to the discharge pipe, and the device itself is equipped with a pipe for discharging the working agent in communication with the storage tank in the area of the openings for the discharge of the working agent and filters through a common collector.

 The proposed device is presented in the drawing, where in FIG. 1 - shows a General view of the device; in FIG. 2 section along A A; in FIG. 3 - section along B B; in FIG. 4 section along B.

 The proposed device includes a storage tank 1, resting on supports 2 and having a coating 3, in the upper part there is a hole with a loading pipe 4 connected by a flow divider 5 and drain pipes 6. The loading pipes are equipped with screens 7 and 8 (two types). The openings for discharging the working agent have filters 9 with covers 10. A discharge pipe 11 is connected to a downward pipe (not shown in the drawing). In the lower part of the tank there is a discharge pipe 12 and a metering movable nozzle 13, auxiliary nozzles 16 are located on the collector 14, and a collector 16 is attached to the bottom of the storage tank.

 The device operates as follows.

 The low concentration hydraulic mixture comes from the loading pipe 4, is separated and poured out through the pipes 6. Through the screens 7 and 8 (to quench speed), the hydraulic mixture is accumulated in the tank 1. As it accumulates at a fixed distance from the coating, which is maintained constant during operation, in the upper part accumulates water free from the material, passing through the filters 9 into the discharge pipe 11. The material accumulated in the tank to a fixed level is discharged through the pipe 12 by a dosing hydraulic nozzle 13. Pressure water fed through the collector 16. For auxiliary purposes (cleaning the bottom, etc.) use, if necessary, nozzles 15 from its collector 14 and the water conduit. Pressure and water flow in the collectors create different in need.

 Dosing of material during unloading is carried out by selecting the diameter of the dosing nozzle and changing the distance between the discharge nozzle and the nozzle.
