Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Shown in Figure 1, the horizontal automatic slag-discharging water draining device of a kind of colliery high negative pressure large flow of the present utility model, comprises the cylindrical shell 7 be filled with water, and is respectively equipped with upper cover and the water inlet 11 for being connected current divider above cylindrical shell 7; Cylindrical shell 7 inside of corresponding upper cover is provided with the ball float 6 for generation of buoyancy, and for the centre pilot bar 5 of the vertical movement of ball float about 6, centre pilot bar 5 is connected with the pallet 3 being adsorbed on cylindrical shell upper wall, pallet 3 is distributed with the side guide peg 4 making centre pilot bar 5 to side movement; Be provided with the swirl-flow devices 10 of water conservancy diversion in the cylindrical shell 7 of corresponding water inlet 11, cylindrical shell 7 sidewall is provided with draining valve 8.On cover the negative-pressure balancing pipe 2 be distributed with for equilibrium pressure, and the atmos-valve 1 be communicated with air when discharging water.Rail wheel 9 is provided with below cylindrical shell 7.
The inside of cylindrical shell 7 is provided with ball float 6, centre pilot bar 5, pallet 3, and under buoyancy of water effect, ball float rises, and backs down atmospheric valve 1, under the effect of negative-pressure balancing pipe 2, carries out Auto-drainage.
As shown in Figure 2, automatic slag-discharging water draining device 1-3 is lifted on extraction system pipeline 1-1 (supervisor, arm and extraction borehole tube connector) low-lying place, be connected with pipeline diverter by negative pressure tube connector 1-2, pipeline ponding enters automatic slag-discharging water draining device through swirl-flow devices 10 under negative-pressure balancing state, and the pipeline be communicated with water inlet 11 is provided with butterfly valve 1-4.Drive ball float 6 to rise along with the water surface rises, open atmos-valve 1 when ball float 6 rises to top dead centre, close negative-pressure balancing pipe 2 simultaneously.Be now malleation in automatic slag-discharging water draining device, under hydraulic pressure effect, draining valve 8 is opened, and tailrace starts draining.Along with water level is down to lower dead center, ball float declines and pulls centre pilot 5 to drive pallet 3 to decline, and atmos-valve 1 cuts out, and negative-pressure balancing pipe 2 is opened simultaneously.Be now negative pressure in tailrace, draining valve 8 cuts out.Water enters automatic slag-discharging water draining device under gravity.Automatic slag-discharging water draining device working in reciprocating mode, realizes automatic slag-discharging water draining.
Beneficial effect and the technical characteristics of this device are:
1, there is adaptation negative pressure of suction scope wide, be suitable for range of negative pressure: 0.00Mpa ~-0.09Mpa;
2, deslagging is effective, and maximum deslagging particle is Φ 25mm-Φ 50mm;
3, the speed that discharges water is fast, automatic draining speed: 30-50L/min (interval discharges water);
4, easy to maintenance, draining valve, water intaking valve and cylindrical shell can be opened and overhaul.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
