Abstract

The invention relates to mining and m. used for gravity transport of backfill mixtures through the pipeline (TP) in the development of fields with the laying of the goaf. The purpose of the invention is to increase the transportation distance of the filling mixture due to the elimination of air drawn in the TP together with the loading filling mixture. For this, the TP consists of a vertical 1 and a horizontal 2 plots, which are installed and fixed in the place of their connection with the gaps of a node between them for exhausting air from the TP made in the form of a conical casing 3 with openings 5 in the upper part. In the hole 5 are placed check valves (OK) 6 with floats 7. Moreover, OK 6 are rigidly connected with floats 7. In the absence of air in the pulp, water from the conveyed mixture enters the casing 3, which raises the floats 7. The latter float and block OK 6 openings 5 , preventing the discharge of slurry from the TP. 2 Il. 1 (L S ON Y O XJ 4 O Fig. 2

Description

The invention relates to mining and can be used for gravity transport of backfill mixtures through the pipeline in the development of fields with the laying of the developed space.

The purpose of the invention is to increase the transportation distance of the filling mixture. due to the elimination of air sucked into the pipeline along with the loaded filling mixture.

Figure 1 shows a filling pipeline with a node for exhaust air, a general view; figure 2 - node for air exhaust, longitudinal section.

The pipeline for gravity transport of the filling mixture consists of a vertical loading 1 and horizontal transport 2 sections and an air exhaust unit made in the form of a casing 3 with a cover 4 welded to it, in which there are holes 5 with check valves 6 placed in them, in the lower part rigidly connected to the floats 7. Vertical 1 and horizontal 2 sections are arranged relative to each other with a gap, with casing 3 covering the gap and welded to both sections of the pipeline.

The stacking pipeline operates as follows.

The filling mixture entering the horizontal funnel of the vertical section 1 is then transported along the horizontal section 2 to the filling holes. The air captured by the pulp, when moving along the vertical section 1, accumulates and, being in a compressed state,

it is pulled out through the gap into the casing 3 and further through the holes 5 in the lid 4, lift the valves 6, goes out into the atmosphere. In the absence of air in the pulp, the water from the transported slurry enters the casing 3, which raises the floats 7. The latter, floating up, block the valves 6 of the openings 5 fixed to them, thus preventing the slurry from discharging from the pipeline. In this case, a pressure is created in the casing 3, which is equal to the pressure of the slurry column in the vertical section 1.

Claims (1)

The elimination of air sucked into the transport pipeline in all modes of operation reduces the pressure pulsation of the mixture, while ensuring stable operation and an increase in the transportation distance of the filling mixture. Claims of the Invention Pipeline for gravity transport of the filling mixture, including vertical loading and horizontal sections, a node with a non-return valve for exhausting air from the pipeline, characterized in that, in order to increase the transportation distance of the filling mixture, by eliminating the air sucked into the pipeline along with the loaded filling gas mixture, the node is installed and rigidly fixed at the junction of the vertical and horizontal sections of the pipeline with the gap between them and Full a conical housing with openings at the top, in which check valves are arranged with the floats, the valves are rigidly connected to the floats.
