Abstract
The utility model discloses a pneumatic drain system for deep hole, relating to a device for draining accumulated water in explosion arranging holes for open-pit mining. The draining methods which are widely used at present are to arrange a diving pump in water in a hole for pumping, and the system has high requirement of manufacture and difficult maintenance. The pneumatic drain system for deep hole has light weight, low requirements for manufacture and maintenance, and small power consumption. An inflation plug and a leakproof film which are inflated into compressed air can be expanded to seal the mouth of the hole and adhere to the wall of the hole, and then the compressed air can be inflated into the hole, so that high pressure can be formed in the hole, and the accumulated water can be drained out of the hole. The inflation plug and the leakproof film can be wound up by expelling the air in the inflation plug and the leakproof film. The pneumatic drain system for deep hole can easily realize the mechanization of operations by using the compressed air as the motive power.
Description
Vapour-pressure type deep hole dewatering installation is that a kind of mining explosive that relates to is placed the employed equipment that drains the water away in the big gun hole.Get rid of the method that ponding extensively adopts water pump to draw water in the big gun hole at present, can use common water pump for the big gun hole that the degree of depth is more shallow, the suction effect that utilizes atmospheric pressure to cause is extracted water out from the aperture in the hole.Then must use submersible pump for the big gun hole that the degree of depth is darker, pump is placed water, use high pressure outside the water tap.
Get rid of ponding in the big gun hole, owing to be field work, the difficult motor-driven of using of water pump.To this, the power that is extensive use of automobile or other dynamic power machine drives oil pump, and the pressure oil that produces with oil pump drives and places the oil motor in the hole to drive water pump again.
The manufacturing technology and the cost of this drainage system oil pump, oil motor, water pump are higher, and at present China's manufacturing technology of only introducing the hydraulic pressure deep hole oil motor of part and water pump from the U.S. will spend the foreign exchange of hundreds of thousands dollar.Since the oil motor water pump to be placed water when using, thus also high to their water-tight performance, corrosion resistance requirement, bring bigger difficulty to maintenance.For one dark 15 meters big gun hole, deliver to the oil motor that places water to the pressure oil that oil pump produces on the other hand, the loop of oil circuit will reach more than 30 meter, and the loss of energy is appreciable.
Adopting vapour-pressure type deep hole dewatering installation is that a kind of like this system will be provided, its not only easy low cost of manufacture, and also energy loss is little, easy to use and maintenance.The concrete structure of this device is provided by its schematic diagram.
Structure and working condition thereof below in conjunction with this device of description of drawings.
This device mainly comprises air pump (1); Distributing valve (2); Draining gas circuit (3); Inflation gas circuit (4); Gutter (5); Inflation plug (6); Leakproof film (7) is formed.(8) be the big gun hole.
During use, at first gutter (5), Inflation plug (6) and leakproof film (7) are put into the big gun hole, priming pump (1), make Inflation plug (6) inflation by inflation gas circuit (4), inwall to big gun hole (8) produces the pressure seal aperture, after pressure reaches required numerical value, promptly inflate to leakproof film (7), make it to expand and closely paste mutually with big gun hole (8) inwall, to reduce as far as possible because the pressure-air that charges in the hole that the factor of geologic structure may cause is outwards overflowed by the aperture or the crack of hole wall, make big gun hole inner product water section become airtight space, at this moment distributing valve (2) cuts off inflation gas circuit (4), inflates in deep hole by gas circuit (3), and the air pressure in hole is increased, ponding is under the effect of gas pressure, outside gutter (5) tap in the hole.Draining finishes by the effect of distributing valve (2), and the air in Inflation plug (6) and the leakproof film (7) is extracted out, at this moment can get up gutter (5), Inflation plug (6), leakproof film (7) rolling.
Because the drainage works part weight of vapour-pressure type deep hole dewatering installation is lighter, and be that compressed air flexible, that event utilizes air pump to produce can make draining realize mechanization as power easily.
Claims (3)
1, a kind of vapour-pressure type deep hole dewatering installation of getting rid of ponding in the surface mining explosive putting hole that is used in.This device is made up of air pump, gutter, Inflation plug, leakproof film.
The feature of this device is to expand the Inflation plug (6) that blocks the aperture after having one to charge into gas, and is adjacent to the leakproof film (7) of hole inwall after the inflation.
2, dewatering installation according to claim 1 is characterized in that making deep hole ponding partly form an airtight space behind Inflation plug (6) and leakproof film (7) inflation.
3, dewatering installation according to claim 1 is characterized in that charging into compressed air in the airtight part of deep hole (8).
