Abstract
The invention discloses a device for intensively and fast draining water in a downward drainage drill hole. The device is characterized in that a three-way hole-sealing sleeve pipe composed of an inner pipe and an outer sleeve pipe is arranged in a drainage drill hole; an annular chamber used as an airflow channel is arranged between the side wall of the inner pipe and the side wall of the outer sleeve pipe, and an external air delivery pipe is communicated with the annular chamber; the inner pipe is used as a draining pipe, a nozzle at the bottom of the draining pipe is connected with a draining hose used for being inserted in the bottom of the drainage hole; the nozzle at the top of the draining pipe is provided with a water draining valve; and one path of the external air delivery pipe is connected with a high-pressure air pipe by an air inlet valve, and the other path is connected with a drainage pipeline by an air discharge valve. The device can effectively drain the accumulated water in the downward drainage hole, and ensure gas drainage effect.
Description
Technical field
The present invention relates to a kind of following in the coal mining of being applied in to extraction boring dewatering installation.
Background technology
Because ponding can't be along with extraction automatic discharge in hole in boring under the gas drainage under suction, therefore also can't utilize the pipeline tailrace to discharge water, accumulate a large amount of water in causing holing, and along with the prolongation of extraction time, the water that accumulates in the hole is also just more and more, has a strong impact on the gas drainage under suction effect.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of and concentrate quick dewatering installation to extraction boring down, so that can effectively discharge down the ponding in extraction boring, guaranteeing the gas drainage under suction effect.
Technical solution problem of the present invention adopts following technical scheme:
Concentrating the design feature of quick dewatering installation to extraction boring under the present invention is in extraction boring the threeway sealing of hole sleeve pipe that is made of interior pipe and outer tube to be set, have the annular chamber as gas channel in described between the sidewall of pipe and outer tube, external appendix is communicated with described annular chamber; With pipe in described is gutter, connects the scupper hose that is used to be inserted in the extraction foot of hole on the mouth of pipe of the bottom of described gutter; On the mouth of pipe of the top of described gutter, draining valve is set; Described external appendix is leaded up to admission valve and is connected with high-pressure air hose, and another road is connected with extraction pipeline by outlet valve.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention utilizes high-pressure blast to realize automatic draining, to the ponding problem of boring, improves the extraction effect under solving effectively.
2, the present invention can divide into groups to implement, and once can get rid of the ponding in a plurality of borings, thereby realizes efficiently draining fast.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Number in the figure: 1 extraction boring, 2 appendixs, 3 gutters, 4 draining valves, 5 admission valves, 6 high-pressure air hoses, 7 outlet valves, 8 extraction pipelines.
The specific embodiment
Referring to Fig. 1, present embodiment is in extraction boring 1 the threeway sealing of hole sleeve pipe that is made of interior pipe and outer tube to be set, and has the annular chamber as gas channel between the sidewall of interior pipe and outer tube, and external appendix 2 is communicated with annular chamber; With interior pipe is gutter 3, connects the scupper hose that is used to be inserted in the extraction foot of hole on the mouth of pipe of the bottom of gutter 3; On the mouth of pipe of the top of gutter 3, draining valve 4 is set; External appendix 2 is leaded up to admission valve 5 and is connected with high-pressure air hose 6, and another road is connected with extraction pipeline 8 by outlet valve 7.
Shown in Figure 1, during normal extraction, outlet valve 7 is in opening, and draining valve 4 and admission valve 5 all are in closed condition.Wherein, closing of admission valve 5 is for avoiding high-pressure blast to enter extraction pipeline; It is for preventing that outside air from entering extraction boring 1 by gutter 3 and influencing extraction that draining valve 4 is in closed condition.
During central drainage, outlet valve 7 is in closed condition, suspend the extraction of gas, at this moment, admission valve 5 and draining valve 4 all are in opening, and the unlatching of admission valve 5 makes high-pressure blast be introduced appendix 2, and introduce in the extraction boring 1 by appendix 2, because the pressure of high-pressure blast, the ponding in the extraction boring 1 is by draining valve 4 emptying swimmingly.
Claims (1)
1. concentrate quick dewatering installation to extraction boring under one kind, it is characterized in that in extraction boring (1), being provided with the threeway sealing of hole sleeve pipe that constitutes by interior pipe and outer tube, have the annular chamber as gas channel in described between the sidewall of pipe and outer tube, external appendix (2) is communicated with described annular chamber; With pipe in described is gutter (3), connects the scupper hose that is used to be inserted in the extraction foot of hole on the bottom mouth of pipe of described gutter (3); Draining valve (4) is set on the top mouth of pipe of described gutter (3); Described external appendix (2) is leaded up to admission valve (5) and is connected with high-pressure air hose (6), and another road is connected with extraction pipeline (8) by outlet valve (7).
