Abstract
The utility model relates to a water jet stream dedusting ventilator which is a dedusting machine for the local ventilation of mines, comprising a machine casing, a wind collector, a water pipe, a flow stabilizer and a nozzle. In the utility model, the water is jetted in a high speed from the nozzle to the air in an air duct through the pressure, which makes the pressure difference is generated between the wind collector and the nozzle. Thus the air with powder dust can flow from the wind collector to the air duct, and the harmful dust of the air is mixed with the water mist, which can purify the air. The utility model has the advantages of simple structure and safety.
Description
The utility model is a kind of mine ventilation dedusting machinery, utilizes the water jet dedusting fan of press water as power.
Harmful dust on the mine, association is very big to the healthy prestige of worker, especially at the digging laneway work plane, and present dedusting machinery, because volume is big, complex structure, accommodation is little, apply and be restricted, as " world's colliery engineering " 1986 that information institute of Ministry of Coal Industry publishes, NO5, a kind of cleaner of 7～13 contained U.S., this is a kind of equipment that utilizes press water as dust removal by ventilation, its injection apparatus is made up of 12 nozzles, is installed on the plane of square casing, and the shortcoming of this machine is that efficient is low, blast is low, air quantity is little, can not connect ventilating duct, so the scope of application is little." the coal engineer " 1986 that publish of Chongqing research institute of coal science institute and for example, NO6,1～6 a kind of Wet-type dust-removal fan of being given, this is the dedusting fan of the present production application of China, this machine is mainly by axial fan, motor, dust arrester and unidirectional screw pump are formed, the air that contains dust is inhaled into ventilating fan by the formed negative pressure of impeller high speed rotating, mix with the spray water that the nozzle that is arranged in impeller the place ahead sprays then, reach dust removing effects, this dedusting fan weighs more than 1,500 kilogram, power of motor reaches 18.5 kilowatts, complex structure, price is expensive, and is very inconvenient for the tunnel that section is little, to containing the high place of gas density, poor safety performance.
The purpose of this utility model just provides a kind of water jet dedusting fan simple in structure, safe and reliable, adaptable.
The task that the utility model proposed is finished by following measure.
Cylindrical shell one termination wind collecting unit, a fluidic device is axially adorned in the center, and fluidic device is made of nozzle and flow straightener, flow straightener one termination nozzle, an end is connected with water pipe, the water pipe external pressure water line of casing of extending.
Advantage of the present utility model is, and is simple in structure, easy to maintenance, volume is little, in light weight, complete machine has only 10 kilograms, so convenient in carrying is suitable for various different sections tunnel; This machine does not have motor, does not have movable part yet, thus safe and reliable, also available in the high concentration gas place.In addition, energy-saving effect is also very outstanding, has only 1/4th of " coal engineer " dedusting fan of giving.Cost has only its 1/10th.
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is left views of the present utility model.
Accompanying drawing 3 is sectional views of injection apparatus.
3～5 spray orifices 8 are arranged on the nozzle 7, and 2.5～4 millimeters of diameters, two ends band horn mouth 9, bell-mouthed cone angle are 30～50 degree.Inwall plating one deck anti-rust metal in hole or edge antifriction alloy sleeve pipe.
The housing of flow straightener 11 processes with common iron, and core body 10 is to be made by 6～10 long sheet metals of 40～60 millimeters, and sheet metal need be used rush-resisting material.
Press water is generally provided by water pump, the static pressure water under the also available mine, the pressure of water must 25 kgfs/centimetre
2～40 kgfs/centimetre
2, the displacement of water pump is at 50～80 liters/minute, and the pump motor capacity gets final product at 5～7 kilowatts.
Adopting injection diameter is the nozzle in 3 millimeters, three holes, and the core body length of flow straightener is that 50 millimeters 8 stainless steel substrates are made, and the casing diameter is 600 millimeters, connects 25 meters glass fiber reinforced plastic ventilating ducts, when press water reach 30 kgfs/centimetre
2The time, water consumption is 56 liters/minute, the air quantity of generation is 223 meters
3/ minute, dust removing effects is by 550 millimeters/meter
3Drop to 2 milligrams/meter
3, fan noise has only 50 decibels (A), and the air themperature of work plane also significantly decreases.
Claims (3)
1, the water jet dedusting fan used of a kind of mine local ventilation dedusting is made up of casing and injection apparatus, it is characterized in that, casing 3 one termination wind collecting units 5, adorn an injection apparatus 4 at the center of casing 3, injection apparatus is made of nozzle 7 and flow straightener 11, and flow straightener is connected with water pipe 2.
2, the described blower fan of claim 1 is characterized in that spray orifice 8 two of described nozzle are horn mouth 9.
3, the described blower fan of claim 1 is characterized in that the core body 10 of described flow straightener is made of 6～10 long sheet metals of 40～60 millimeters.
