Abstract
Provided is an assembly method of a vacuum drainage system for a mine shaft. The vacuum drainage system is composed of a cement pit, a perforated strainer, a support, an inductor, a water level alarm, control valves, a vacuum water pumping pipe, a vacuum box, a top board, vacuum pumps, air suction ports, a liquid level indicator, a vacuometer, a water inlet bent pipe, a drainage pipe and a controller. The support is installed at the bottom of the cement pit in the mine shaft, the vacuum water pumping pipe is installed on the support, and the perforated strainer is installed above the cement pit; the vacuum box is installed on the ground, the top board is installed above the vacuum box, and the top board and the vacuum box are installed oppositely; the vacuum pumps are installed on two sides of the upper side of the top board, and the controller is installed on one side of the vacuum box. The assembly method resolves the technical problem that the suction stroke of a water pump in an existing drainage device is insufficient, can achieve complete drainage of accumulated water in an underground water bin of a deep mine, reduces consumption of electric energy, improves the utilization rate of the water pump, reduces maintenance costs of the water pump, guarantees safety in production, and effectively resolves the problems that the suction stroke of the water pump is limited and water leakage accidents and water inrush accidents occur.
Description
Technical field
The present invention relates to the mine drainage technical field, especially a kind of mine low-pressure drainage system assembly method.
Background technology
At present, in the underground mining process, often all can have descends swelling to go out in large quantities, generally be earlier by the ditch that begins to rehearse to this underground water that pours out, flow into water lodge in the mode that flows naturally, by the dewatering installation of sump water is concentrated then to drain into ground, because the water pump that dewatering installation adopts is inhaled the journey weak point, so sump can not design too deeply yet, it is limited that water pump is inhaled journey, water can't be drained, and no matter the drainage pump requirement of sump pump house all will at any time draw water in " peak; paddy; flat " any period of electricity consumption, and this can cause the increase of power consumption, the raising of mining cost, in a single day metal run out in underground mining area, during water leak accident, because sump storage capacity deficiency, do not have more time to allow the workman escape, casualty accident very easily takes place.
Application number is that 87200749.9 patent document has been announced a kind of air pressing type mine drainage device, and displacement is little, and structure is installed complicated, and drainage speed is slow, and the accident of metalling run out is difficult to timely draining in case take place.
In view of the foregoing, now invent out a kind of mine low-pressure drainage system assembly method, the ponding emptying in the water lodge of dark ore deposit can be reduced the consumption of electric energy simultaneously.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, a kind of mine low-pressure drainage system assembly method is provided, can be with the ponding emptying in the water lodge of dark ore deposit, reduce the consumption of electric energy simultaneously, improved the utilization rate of water pump, reduced the maintenance cost of water pump, guarantee safe production, it is limited to efficiently solve water pump suction journey, metals run out the problem of water leak accident.
The present invention adopts following technical scheme to achieve these goals: a kind of mine low-pressure drainage system assembly method is by cement pit, double-edged fine-toothed comb, support, inductor, water level alarm, control valve, vacuum drinking-water pipe, vacuum tank, top board, vacuum pump, extract opening, level indicator, vacuum meter, the water inlet bend pipe, gutter, controller constitutes; Cement pit bottom in the mine arranges support, and the vacuum drinking-water pipe is set on the support, and the cement pit top arranges double-edged fine-toothed comb; Vacuum tank is set on the ground, and the vacuum tank top arranges top board, the corresponding setting with vacuum tank of top board, and top board and vacuum tank junction arrange many group holders, use bolt; Both sides, top board top respectively arrange vacuum pump, and the extract opening of vacuum pump is arranged in the vacuum tank through the preformed hole of top board; Vacuum tank one side arranges controller.
The pump mouth top of vacuum drinking-water pipe arranges inductor, and the inductor top of vacuum drinking-water pipe arranges water level alarm, and at least 3 control valves are set between inductor and the water level alarm; The top board upper center arranges level indicator and vacuum meter, and the water inlet bend pipe is set on the top board, and the water inlet bend pipe is connected setting with the vacuum drinking-water pipe, and the vacuum tank bottom arranges gutter, and control valve is set on the gutter.
Vacuum drinking-water pipe, vacuum tank, top board, water inlet bend pipe, gutter adopt mild steel to manufacture.
Inductor, water level alarm, control valve, vacuum pump are connected setting respectively with controller line.
The invention has the beneficial effects as follows: simple in structure, easy to operate, the mentality of designing concision and compact, long-time running is safe and reliable, has avoided various hidden dangers, safety factor obviously improves, fault rate obviously reduces, and required plant equipment is as inductor, support, valves etc., market all have series of products to choose, to containing acid, the mine water that contains silt also is suitable for, be applicable to the mine that 100-1500 rice is dark, the flow rate calculation formula is: flow equals flow velocity and multiply by sectional area, according to the actual conditions of mine, set out the vacuum of vacuum tank and the diameter of vacuum drinking-water pipe, and set the operations data; Maintenance load is little, and fitting operation is convenient, has improved condition of labor, has reduced labour intensity, and cost of manufacture is low.
Solved the technical problem of water pump suction journey deficiency in original dewatering installation, having realized can be with the ponding emptying in the water lodge of dark ore deposit, reduce the consumption of electric energy simultaneously, improved the utilization rate of water pump, reduced the maintenance cost of water pump, guaranteed safe production, efficiently solving water pump, to inhale journey limited, metal run out the problem of water leak accident.
