Description
The utility model relates to a kind of environmental protection device, especially a kind of atomizing de-dusting apparatus.
At present, condition of work is poor under the many coal mine of China, work under bad environment, especially the transfer point dust pollution in coal-face and the transportation lane is very serious, sunset lung and occupational disease such as coal pneumoconiosis, grievous injury the healthy of mine workers, has caused serious consequence.In order to improve the condition of work of mine, some measurements for reduction have all been taked in various places for a long time.As the mining a bit water pumper in northeast underground water is delivered in the tunnel, water pipe support water spray dust on belt conveyer, it is bigger to do the pipe laying difficulty like this, and for example the Xuzhou Dahuangshan Coal Mine is to adopt centrifugal pump, to spraying water on the belt conveyer, this wants ad hoc cable, and coal mine gas is big, and electrical equipment requires to have explosion precaution.And, more than two kinds of methods all can not automatic water jetting or stop-spraying, every water injector all needs the personal management, cost lot of manpower and material resources, and effect is bad.
The purpose of this utility model is to have designed a kind of novel auto spraying device for reducing dust in order to overcome above-mentioned weak point.It is made up of nozzle, drainpipe, rubber wheel, screw pump, suction hose, catch basin and screen pack etc.It does not need spcific power, but utilize belt conveyer when work, the effect of the gravity of belt tensile force and material, make belt and be installed between rubber wheel on the screw pump power transmission shaft and produce frictional force, drive the rotor rotation of screw pump, by suction hose with water from catch basin in the suction pump, water arrives in the nozzle by drainpipe with certain pressure in pump, make the water ejection that from nozzle, atomizes, reached the purpose of atomizing depositing dust.When belt conveyer was unloaded, belt promptly disengaged with rubber wheel, and pump quits work, automatically stop-spraying.The experiment proved that this device produces desirable atomizing effect, reached the auto spraying depositing dust purpose of the phase of giving, and every required power of pump has only about 200 watts, belt conveyer is not had harmful effect, cost is low, does not need specialized management.
The utility model has following advantage compared with the prior art: utilize the direct drive screw pump work of belt conveyer, do not need spcific power, easy to use, power consumption is little, the atomizing de-dusting effect is remarkable, improved working environment greatly, help the healthy of workman, and it has been simple in structure, make easily, cost is low, and is safe and reliable, can be widely used in coal and ore and the bigger belt conveyer occasion that needs the material of depositing dust of other dust.
