SU964193A1 - Pipeline for hydropneumatic filling in - Google Patents

Description

one

The invention relates to the mining industry and can be used in the hydropneumatic method of laying the space developed.

Known backfill pipeline for hydropneumatic bookmarks, including a mixing funnel, a vertical and horizontal sections of the pipeline, a hydropneumatic pumping device at the end of the horizontal section and a compressed air pipeline 1,

The disadvantage of this pipeline is a greater flow of compressed air from the mine pneumatic network.

In addition, a backfill pipe is known for the hydropneumatic laying of a goaf, including a mixing funnel, vertical and horizontal portions of the pipe, tail pipe and an air intake chamber with a non-return valve, installed-.

at the top of the vertical section of the pipeline 2.

A disadvantage of the known pipeline is the difficulty of controlling the flow into the pipeline of air from the atmosphere, which does not ensure its supply in sufficient quantity and leads to additional energy consumption due to the supply of air from the air-conducting shaft network.

The purpose of the invention is to reduce energy costs due to the () provision. pC of the flow of air from the atmosphere into the filling pipe.

Claims (1)

The goal is achieved by the fact that the filling pipeline is equipped with a pulp flow interrupter, made in the form of a gate valve with a screw. 20 house installed in the pipeline in front of the air intake chamber and on. the pulp collector, made in the form of a vertical section of the pipeline from the mixing funnel to the interruption of a 39 liter pulp flow, increasing in cross section. The drawing shows a diagram of a filling pipeline in operation, a vertical section. The pipeline includes a mixing funnel 1, a pulp storage 2, a pulp flow interrupter 3, an air intake chamber 4 with a check valve. In this case, the breaker 3 and the air intake chamber 4 with a non-return valve are installed along the axis of the vertical rod 5, connected to the rod pipes by means of quick-disconnect couplings. Air is taken from the atmosphere and accumulated in the sections of the vertical rod 5 between the portions of the filling pulp 6. The pulp is aerated in the lower (flooded) part of the vertical rod 7 and the horizontal section 8 of the pipeline. The pipeline works as follows, in the receiving funnel serves stowing material and water. The slurry formed from the pulp fills drive 2, holding up from the further free fall by the flow interrupter 3. As the breaker is opened with 3 slurries in portions, the volume of which is controlled by the number of double strokes of the valve falls under its own weight into chamber C with a check valve and then into a vertical pipeline. Due to the high speed of fall and acceleration of the force of gravity, the air from the atmosphere flows into the chamber k with a non-return valve and the adjacent section of the pipeline 5. The volume of this air is determined by the distance between portions of the pulp 6, i.e., the frequency of the breaker strokes, and may, if necessary, by 5-10 times exceed the volume of the pulp supplied. The slurry aerated in areas 7–8 under natural pressure is introduced into the hydropneumorating apparatus 9 located in the production of the ventilation layer. In the hydropneumization apparatus 9 the three-phase pulp is divided into components. At the same time, due to the air released from the pulp, and the pressure in the apparatus chamber, from 3-4 water is supplied through an independent pipeline and pneumatic transport of the dehydrated stowing material to the place of laying through a separate pipeline. The proposed hydropneumatic pipeline 1 allows the extraction of air from the atmosphere in any quantity necessary for the pneumatic conveyor of the dehydrated material for considerable distances. In this case, water is discharged through an independent pipeline to the local catchment basin. All this allows to expand the field of application of hydropneumatic laying to a larger number of mines and to increase the efficiency of its application. The invention claims. A stowing pipe for hydropneumatic laying of the open space, including a mixing funnel, a vertical and horizontal pipeline sections and an air intake chamber with a non-return valve installed in the upper part of the vertical pipeline section, characterized in that, in order to reduce energy consumption backfill pipe, it is equipped with a pulp flow interrupter, made in the form of a gate valve with a drive, installed in the pipeline in front of the air intake chamber, and the pulp accumulator, made in the form of a vertical pipeline section from the mixing funnel to the pulp flow interrupter, which increases in cross section.
