(54) INSTALLATION FOR HYDRAULIC TRANSPORT

one

The invention relates to hydrotransport of bulk materials, namely, an installation for hydrotransport of bulk materials, and can be used in various fields of national economy in designing sump sumps, transfer stations, loading bulk materials into pressure pipelines with excavators and other excavation and loading equipment.

A known installation for hydrotransport of bulk materials, containing chamber feeders, cavities of which are communicated with a slalom pump through charging ports with check valves. A HC pump with a water pump through a water pipe with shutoff valves, and a main pipeline connected to chamber feeders discharge pipes with check valves 1.

The disadvantage of the installation is the presence in the feeders of an elastic cylinder having a limited service life, the inability to load part of the water when loading the cylinders with pulp to reduce their volume, as well as the inability to separate the material from the pulp when loading the cylinders

material not subject to transportation.

The purpose of the invention is to expand the functionality by providing at the same time as transporting the material its classification.

The goal is achieved by the fact that the installation for hydrotransport of bulk materials is equipped with a receiving hopper installed between the slurry pump and loading nozzles, and each chamber feeder and receiving hopper are equipped with a group of horizontal plastic plates installed one after the other and with an angle to it. surface.

In addition, each boot pat15 logging communicated with the corresponding water pipe.

The drawing shows a General view of the installation for the hydraulic transport of bulk materials.

The installation contains chamber feeders 1, inside of which in the upper part are located the classifying and thickening pulp devices consisting of plates 2 with fins made of plastic.

and stacked one upon another at an angle of 55 ° to the horizon, forming inclined clearances for the pulp stream containing particles to be discharged through conduit 3 with shut-off valves 4 and crawling in the feeders 1 of the material deposited on the inclined planes to be transported through the main conduit 5 In the lower part of the feeder 1 are located the discharge ports 6 with check valves 7 and a water pipe 8 with shut-off valves 4 in such a way as to ensure the unloading of material from the feeders I into the main pipeline one 5 from the bottom up.

The installation also contains a receiving hopper 9 installed between a slurry pump (not shown) and a feeder 1, provided in its upper part with plates 2, under which, on one side of the receiving bunker 9, there is a pipe 10 supplying the original slurry, and on the other side of the receiving bunker above the plates 2 - pipeline 11, dumping pulp containing fractions of the material that cannot be transported through the main pipeline 5.

Receiving hopper 9 and feeders 1 are connected by loading nozzles 12, the upper part of which with non-return valves 13 installed in them is connected to the lower part of receiving hopper 9, and the lower end is inserted tangentially under the plates 2 into the chambers of the chamber feeders so that the nozzles 12 are tilted to the horizon is greater than the angle of repose of the bulk material in the water.

In order to discharge the material of the feeders 1 into the main pipeline 5 and its further transportation, the installation comprises a water pump 14.

To close the check valves 13 installed by the receiving hopper 9 at the ends of the pipes 12, flushing the valves of the check valves with clean water before they are closed, pipes 15 are led from the water pipe 8 to the pipes 12.

To obtain a signal for switching the shut-off valves 4, a level 16 sensor is installed on the feeder 1.

The installation works as follows.

The pipeline 10 original pulp or dry bulk material from the conveyor 17. through the hopper 18 is fed into the receiving hopper 9 under the plate 2.

Depending on the area of the plates 2 and the flow rate of the initial pulp through pipeline 11, pulp containing fractions of the material that cannot be transported via trunk pipeline 5 is dropped, the remaining material in the form of pulp along the walls of the receiving bin 9 flows through the open non-return valve 13 and outlet 12 tangentially into the cavity corresponding chamber feeder 1 for plates 2.

Depending on the area of the plates 2,

installed inside the chamber feeder 1, and the consumption of solid material that displaces water, a secondary classification of the material occurs and through the pipeline 3 water is discharged with residues of that material that was not discharged

 primary classification. The rest of the material is lowered, filling feeder 1 to a certain level, after reaching which the level 16 sensor generates a signal and the locking is switched

, valves 4, the water from the water pump 14 enters the chamber feeder 1, unloading the material into the main pipeline 5.

While the first feeder is loaded with material, from the second feeder 1, material is unloaded into the main pipeline 5. After switching off the shut-off valves 4, the operations are performed in the reverse order.

The gap between the end of the nozzle 6 5 and the end of the pipe 8 in the lower part of the feeder 1 is men, the consistency of the pulp supplied to the main pipeline 5 can be adjusted.

0 The unit allows the water pump to operate not on an abrasive pulp, but on a clean one with good efficiency and minimal wear.

The plant has large 5 passages, which exclude clogging by large inclusions, and therefore, the shutdown of the production line, which increases the reliability of operation.
