Abstract

The invention relates to the mining industry and allows to simplify the design of the device. It includes a carrier fluid supply line (HP) 4, a discharge pipe 18, an ejector mixer 5 installed between them, a feed hopper (BP) 1 connected to mixer 5, a branch pipe 11. The device agitator is designed as an eccentric step

The shaft 8 is mounted coaxially with the PSU 1. It is made with a side hole 17, at the level of which a impeller 9 is mounted on the agitator. The nozzle 11 hydraulically connects the oil supply line 4 to the oil hole 17. When pumped into the well, the fluid flow through the mixer 5, forms a local pressure depression, where

granulated mater 1al (GM) enters from BP 1. The carrier enters BP 1 through port 11 and rotates the wheel 9 and the agitator, which moves the GM to BP 1. So the uniform movement of the GM along the walls of the BP 1 to its discharge opening 2 and GM freezes on BP 1 walls are prevented. 1 Il.

The invention relates to the mining industry, namely to oil and gas production, and can be used in the injection of granular material into the well, for example, in the fight against the absorption of washing liquid.

The purpose of the invention is to simplify the design of the device.

The drawing shows the device, a longitudinal section.

The device consists of a bunker-feeder 1 with a discharge hole 2, a mixing chamber 3, a carrier supply line 4, an ejector mixer 5. A spinner 8 made in the form of an eccentric stepped shaft 8 is mounted on sliding bearings 6 and 7 in the upper part of which the impeller is mounted 9, ne

thinning torque to agitator

by means of the key 10. The torque on the impeller 9 results from the action of the jet taken from the carrier fluid supply line 4 by the nozzle 11 on the impeller 9, and the force of the jet on the impeller 9 is controlled by the valve 12 on the nozzle 1.1. The tightness of the feeder hopper 1 is provided by the lid 13, on which the vacuum meter 14 is attached, and the gasket 15. A safety valve 16 is installed on the case of the feeder hopper 1 and the side opening 17 is made. The ejector mixer is connected to the discharge pipe 18.

The device works as follows.

The feeder hopper 1 is filled with granulated material and closed with a flap 1 3 with a gasket 15.

The supply line 4 of the carrier fluid is connected to the injection line of the pump that pumps the fluid into the well. When pumping a fluid flow into the well, the passage through the ejector mixer 5 forms a local rarefaction in the mixing chamber 3, which leads to the flow of granulated material from the feeder hopper 1 into the mixing chamber 3. At the same time, the liquid entering the feeder 1 through the nozzle 11, rotates the impeller, 9 and the agitator 8, which, using eccentric protrusions, moves granulated material in the feed hopper 1. During the rotation of the bodies in each layer of granulated material, a change in the volume of material occurs due to a protrusion or trough of the agitator, made in the form of an eccentric stepped shaft, which causes the entire layer of granules to move to the peripheral points of the bunker-feeder. This ensures a uniform movement of the granulated material along the walls of the bunker-feeder 1 .. to the discharge opening 2 and prevents the granulated material from hanging on the walls of the bunker-feeder 1. The vacuum gauge 14 serves to obtain information about the pressure in the feed hopper 1 during the injection of granular material into the well. The safety valve 16 reduces the overpressure in the silo feeder 1 at the time of the end of the injection process.
