Abstract

The utility model relates to a colliery is dustproof facilities in the pit, specifically is dirt net is caught in pit automatically in colliery, solves the current dirt net efficiency of seizing dust that catches and hangs down, is difficult to clean network and goes up the mine dust, and traffic is current inconvenient, and life is short to and the waste water problem of resource, the scheme: including moving crosswise spool and the explosion proof machine of spool end in the tunnel, spool upper portion is fixed with the fixed network, the spool has the activity and catches the dirt net, and last division of movable screen has pedestrian's door, catching dirt net both sides and being provided with the spraying water curtain respectively, including atomization water pipe and atomizer, every shower nozzle is all towards catching the dirt net and being the decurrent contained angle of 45 slopes with it, still include the infrared sensor and the controller of tunnel both sides group, the controller is connected with explosion proof machine and spraying water curtain respectively. The advantage: 1, catching dirt net efficiency of seizing dust and improving greatly, it is clean easier to catch the dirt net, 2, traffic is through convenient, 3, waste water utilizes again, catches dirt side off the net and is difficult for ponding, and the security improves, the supervisory control of being convenient for.

Description

The automatic Dust collecting net of underground coal mine

Technical field

The utility model is related to mine underground dustproof equipment, the specially automatic Dust collecting net of underground coal mine.

Background technology

In coal production transportation, the generation of mine dust is inevitable.Mine dust influence safety in production while, Also long-term threat underground worker's is healthy.Dust collecting net, existing Dust collecting net is generally used to use in tunnel depositing dust at present When, although mine dust can be reduced, improves operating environment, but there is following defect：1st, spray generally is set in the over top of Dust collecting net Mist water-curtain, it can not fast and effectively increase the spray effect on Dust collecting net, in addition the mine dust on Dust collecting net also be difficult to clear Wash, cause the dirt effect of catching of Dust collecting net gradually reduces with the lengthening of use time；2nd, existing roller shutter type Dust collecting net, is expert at When people and mine car pass through, it is both needed to roll whole Dust collecting net, not only easily causes the abrasion of Dust collecting net jack, reduces Dust collecting net Service life, and cause walk slow, reduce production efficiency；3rd, the water that existing Dust collecting net spraying water curtain sprays does not have There is recovery, easily cause tunnel internal water accumulation seriously, be unfavorable for safety management, while also resulting in the waste of water resource.It is existing in order to solve There is the defect of Dust collecting net, be badly in need of a kind of automatic Dust collecting net in New Coal Mine underground of design.

The content of the invention

It is low that the utility model solves existing Dust collecting net efficiency of seizing dust, it is difficult to cleans online mine dust, and vehicles and pedestrians are not square Just, service life is short, and waste water resource problem, there is provided a kind of automatic Dust collecting net of underground coal mine.

The utility model is achieved through the following technical solutions：The automatic Dust collecting net of underground coal mine, including cross-arm is in tunnel The Dust collecting net jack of middle and upper part, the Dust collecting net jack includes Dust collecting net spool and installed in Dust collecting net spool termination Fire-proof motor, connect flexible Dust collecting net on the Dust collecting net jack, the flexible Dust collecting net includes being fixed on catching dirt Fixed net and the movable Dust collecting net that is arranged between Dust collecting net spool and the lateral wall of tunnel two between net volume axle and tunnel top, institute State and pedestrian's door is provided with movable Dust collecting net；The tunnel both sides that the flexible Dust collecting net is separated out are respectively arranged with a set of spray water Curtain, it is described spraying water curtain include be arranged at the spraying water pipe at the top of the lateral wall of tunnel two and tunnel and be connected with spraying water pipe it is many Individual atomizer, each described atomizer is in 45 ° of angles diagonally downward towards flexible Dust collecting net and with flexible Dust collecting net； Also include the controller for being arranged at the infrared sensor of the lateral wall of tunnel two and being connected with infrared sensor, the controller is also distinguished It is connected with fire-proof motor and spraying water curtain.Fixed net closing Dust collecting net reel upper cross section, movable Dust collecting net is rolled up by Dust collecting net Axle drives closing lower cross section, controls fire-proof motor to roll movable Dust collecting net, clearance car by infrared sensor and controller Pass through.Controller also controls spraying water curtain towards flexible Dust collecting net water spray.Atomizer is towards flexible Dust collecting net and therewith In 45 ° of angles diagonally downward so that ejection efficiency is greatly improved, not only water smoke linked network effect is more preferable, and facilitates flush clean Mine dust on flexible Dust collecting net.Pedestrian's door is provided with movable Dust collecting net, pedestrian passes through to pass through by need not rolling movable Dust collecting net, Improve pedestrian by efficiency.

The movable Dust collecting net bottom is with being provided with edge facing to the inclined waste water collection tank of lateral wall of tunnel one, the waste water The relatively low one end of collecting tank is connected with collection water pipe, and the collection water pipe is connected with the sewage collecting box with pressure filter, The sewage collecting box is connected by electrical ball valve with spraying water pipe, the electrical ball valve and sewage collecting box by holding wire with Controller is connected.Be collected for the waste water fallen on flexible Dust collecting net by waste water collection tank, and waste water receipts are flowed into by collecting water pipe Header, the waste water in sewage collecting box reenters spraying water pipe and is used after filter-press by electrical ball valve.Control Device control sewage collecting box carries out filter-press to waste water, and control electrical ball valve is opened, and the water after purification is followed into spraying water pipe Ring.

The utility model has advantages below：1st, Dust collecting net efficiency of seizing dust is greatly improved, and Dust collecting net cleaning is easier；2nd, car Pedestrian is by convenient；3rd, waste water is re-used, and Dust collecting net lower section is difficult ponding, and security is improved, and is easy to manage control.
