Description

one

This invention relates to the field of hydraulic transport.

Devices are known for the hydraulic supply of solid materials to transport pipelines, wires of pressure hydraulic installations, containing chambers, each of which is equipped with an upper loading gate, a drain pipe and a pressure pipeline that supplies water for unloading material from the chamber into a transport pipeline, the intake end of which located above the bottom of the chamber.

The main disadvantage of these devices is the unstable unloading process, the unevenness of the material supply to the transport pipeline, and the unreliability of controlling the ratio of solid and liquid (water) volumes.

The purpose of the invention is to increase the stability of the process of unloading material from chambers with a given capacity and ensuring regulation of the ratio of 01 volumes of solid and water.

This goal is achieved by the fact that each chamber is provided with a nozzle connecting the nozzles connected to the pressure and transport pipelines, and in the lower part of the walls of the nozzles facing each other, longitudinal holes are formed that are covered by a gate. To exclude

getting into and discharge of solid lump materials the drain pipe is connected to the chamber by means of a perforated pipe vertically installed in each chamber.

FIG. 1 shows the described device; in fig. 2 - camera device with cuts along A- / 1 and BB.

The device contains chambers /, each of which has an upper charging gate 2. Pressure chambers 3, drain 4, and transport 5 pipelines are connected to the chambers, which are provided with valves 6, 7 and 8, respectively. Pressure pipe 9 and transport 10 nozzles. The combined nozzles 9 and 10 form the dispenser tip. The open end of the tip faces the bottom of the chamber. Between the bottom of the chamber and the end of the tip there is a gap, the size of which is (1,2-l, 5) dfij, where ytg is the diameter of the transport nozzle 10. In the lower part of the pressure 9 and transport 10 nozzles of the dispenser tip are formed longitudinal holes are wide (0,8-1,0) tr; along the length of 1.5, where - Diameter of the transport pipeline 5. The longitudinal holes of the pipes 9 and JO are covered with a gate // with a drive 12. A perforated pipe is vertically installed in the chamber

13, connected to the drain 4 and pressure 3 pipelines, as well as with a pressure connection 9.

The bottom of the chamber has an inclined wall and an elongated pad 14 corresponding to the cross section of the tip end where the material enters under the action of its own weight.

The described device operates as follows.

The chambers are loaded and unloaded alternately. Before the next loading of the chamber of the apparatus, the drain valve 7 and the upper loading valve 2 are opened. Water is drained from the chamber to a certain level, after which the drain valve 7 is closed and the charging material is fed into the chamber, which together with the remaining water fills the chamber until the upper level is reached. loading mouth of the camera. Then close the shutter 2, open the shutter 8 of the transport pipeline and the shutter 6 of the discharge pipe. At the same time, the closures 6 VI 8 of the second chamber of the apparatus are closed, i.e., the unloaded chamber is disconnected from the discharge and transport pipelines.

Pressure water is fed into the loaded chamber through two pressure pipelines, one of which is connected to the upper part of the chamber, the other is directly connected to the dispenser.

The main flow of water is supplied to the upper part of the chamber, the capacity of the child increases with decreasing material height in the chamber during unloading, as the cross section of the perforated pipe 13, which is freed from the material, increases and its hydraulic resistance decreases. The pressure flow of water at the same time displaces the slurry water from the upper part of the chamber through a perforated pipe.

All pressurized water supplied to the chamber of the apparatus enters the discharge port 9 of the dispenser and is directed to the bottom of the chamber into the gap formed between the end of the dispenser tip and the bottom. In this gap comes under its own weight material. Pressure water captures the material and transports it to the pipe 10 of the transport pipeline.

Using the gate // overlap the longitudinal holes of the pipes 9 and 10 and regulate the amount of water flow, exciting material, and the ratio of solid material and liquid (T: W).

.When the nozzles are completely open, the flow of water passes through them, without capturing the material. As the holes overlap with a gate, the speed and power of the flow affecting the material being discharged increases. With the longitudinal openings completely blocked, the flow of water passes mainly through the material, which corresponds to the maximum capacity.

on the paged material and the highest T: G value. The specified device performance is achieved by setting the gate // to a certain position by means of the J2 drive.

The drain pipe 4 is connected to the chamber through a perforated pipe 13, which prevents solid bulk material from entering the open drain pipe when loading, draining or accidentally entering the material into the chamber when the top closure 2 is open during the discharge of water from the chamber.
