Abstract
The utility model discloses an automatic water drainage slag discharge device for a mine gas drainage system. The slag discharge device for the mine gas drainage system is suitable to be used in the gas drainage system under a well of coal mine and comprises a V-shaped pipeline connected with a gas drainage pipeline; the bottom of the V-shaped pipeline is provided with a slag collection spherical cavity; a slag discharge door is arranged at the bottom of the slag collection spherical cavity; two branch pipelines of the V-shaped pipeline are provided with a water drainage door and a switch respectively; and a floater is arranged in the branch pipeline of the water drainage door and is connected with the switch through a corrosion prevention steel wire. The automatic water drainage slag discharge device is simple in structure, small in size, low in cost, and convenient to install and easy to operate.
Description
Technical field
The utility model relates to a kind of slag-discharging device that discharges water, the mining gas discharging system that is particularly useful in gas drainage system, using under a kind of coal mine slag-discharging device that discharges water automatically.
Background technology
The deslagging mode that discharges water of the gas drainage system of down-hole use at present mainly contains two kinds:
Mode manually discharges water; It is also relatively more extensive that the present down-hole of this mode is used; Need the professional to go manually to discharge water, particularly water reaches often that extraction pipeline is long more to need many people remove the deslagging that discharges water specially with the extraction system mine that distributes widely in extraction pipeline, relatively wastes time and energy everyday.
Automatic tailrace of electric power or general automatic tailrace, the automatic tailrace of electric power need set up cable and sensor installation specially; In the extraction pipeline of temporary erection, just be difficult to install this tailrace; And needing aboveground corresponding supporting checkout equipment, cost is high, complicated operation; General automatic tailrace mostly is that bulky construction is complicated, and damages than being easier to, and purchase cost is not low yet.
Summary of the invention
The purpose of the utility model provides a kind of easy to use, and cost is low, the mining gas discharging system simple in structure slag-discharging device that discharges water automatically.
For achieving the above object; The mining gas discharging system of the utility model slag-discharging device that discharges water automatically comprises the V-arrangement pipeline that is connected on the gas drainage under suction pipeline, and the bottom of V-arrangement pipeline is provided with spherical slag trapping cavity; Spherical slag trapping cavity bottom is provided with ash gate; Be respectively equipped with wicket and switch on two bye-passes of V-arrangement pipeline, be provided with float in the bye-pass of wicket, float is connected with switch through the anticorrosion steel wire.
The said V-arrangement pipeline that is connected on the gas drainage under suction pipeline is asymmetric V-arrangement pipeline.
Beneficial effect:, realize that through float water discharges water completely automatically in the V-arrangement pipeline, through closing switch isolation gas path owing to adopted technique scheme; Thereby can open bottom ash gate cleaning solid dregs, volume is little, and is simple in structure; Easy for installation, cost simple to operate is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: flange-1; Anticorrosion steel wire-2; Float-3; Wicket-4; Spherical slag trapping cavity-5; Ash gate-6; Switch-7; V-arrangement pipeline-8.
The specific embodiment
To combine accompanying drawing that the embodiment of the utility model is done further description below:
As shown in Figure 1: the mining gas discharging system of the utility model slag-discharging device that discharges water automatically mainly is made up of flange 1, anticorrosion steel wire 2, float 3, wicket 4, spherical slag trapping cavity 5, ash gate 6, switch 7 and V-arrangement pipeline 8.V-arrangement pipeline 8 is located on the gas drainage under suction pipeline through the flange 1 at two ends; Spherical slag trapping cavity 5 is located at V-arrangement pipeline 8 bottoms; Spherical slag trapping cavity 5 bottoms are provided with ash gate 6; Be respectively equipped with wicket 4 and switch 7 on two branch roads of V-arrangement pipeline 8, be provided with in the V-arrangement pipeline 8 in the branch road of wicket 4 wherein and be provided with float 3, float 3 is connected with switch 7 through anticorrosion steel wire 2; Guarantee that whole device is in vertical state as shown in the figure when connecting, can be normal practical to guarantee whole V-arrangement pipeline, after device installs, guarantee that switch 7 opens, ash gate 6 is closed, and wicket 4 is normally closed under action of gravity.In extraction pipeline, there are flowing out; Flow to the V-arrangement pipeline under the action of gravity; Because this device two all is connected in the extraction pipeline, so the air pressure at V-arrangement pipeline two ends is identical, therefore do not receive the influence of extraction negative pressure; Float 3 is floated come and discharge water stretching the opening wicket 4 pull-ups automatically of 2 anticorrosion steel wires when water reaches; Using the purpose of anticorrosion steel wire 2 is exactly in the process of discharging water, to remain wicket 4 to be in the state that is not had by water logging all the time, and does not cause in the extraction pipeline gas excessive, guarantees that the extraction effect is unaffected.Therefore only because slag ratio is less in the extraction pipeline, and spherical slag trapping cavity 5 volumes are bigger, need regularly carry out manual deslagging, during deslagging, close switch 7 earlier, open ash gate 6 then and carry out deslagging and get final product.
