Description
Technical field
The utility model relates to a kind of weary elegance acquisition means, is specifically related to a kind of mine air-lack harvester.
Background technology
The mine air-lack utilization is progressively risen in China, and the collection of weary wind is the key that weary wind utilizes.Mine Ventilator outlet retention tower has two kinds of steel and steel concrete, the steel concrete retention tower divides again square and circular two kinds, steel retention tower and square bar reinforced concrete retention tower air outlet are low apart from ground, highly about 8～12m, retention tower air outlet and fan room have a segment distance in the horizontal direction, be relatively independent, be convenient to set up weary elegance collection suspended hood; And circular steel reinforced concrete retention tower air outlet is high apart from ground, highly about 20～25m, the conjuncted layout of retention tower and fan room, retention tower is positioned at fan room central authorities, this kind retention tower to set up weary elegance collection suspended hood relatively more difficult.At present the collection of the weary wind of circular steel reinforced concrete retention tower high altitude discharge be there is no precedent.
The utility model content
The utility model overcomes the deficiency that prior art exists, and it is high that technical problem to be solved has provided a kind of collecting efficiency, safe and reliable mine air-lack harvester.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the mine air-lack harvester, comprise: suspended hood and support, described suspended hood is installed in the top of ventilation fan retention tower by support, described suspended hood comprises exhaust duct, wind loop and aspiration channel, described exhaust duct is rack-mount, and the bottom of exhaust duct is inserted into the top of ventilation fan retention tower, the top of described exhaust duct is connected with wind loop by flange, the inside of exhaust duct is provided with central dividing plate, the both sides of exhaust duct are provided with an aspiration channel, and the inside of described aspiration channel is provided with deflector.
Laterally and on the vertical direction be provided with reinforcing rib around the described exhaust duct.
Be provided with airtight curtain on the circumference of described exhaust duct and fan room retention tower junction.
The beneficial effect that the utility model compared with prior art has is: the utility model is by installing suspended hood additional at the ventilation fan retention tower, weary wind is difficult for by Dilution air, guarantee the weary wind that the Mine Ventilator retention tower is discharged, maximal efficiency imports weary wind oxidation unit and destroys, it is high to gather weary wind efficient, improves the reliability of Safety of Coal Mine Production.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment
As shown in Figures 1 to 4, the mine air-lack harvester, comprise: suspended hood 1 and support 2, described suspended hood 1 is installed in the top of ventilation fan retention tower 3 by support 2, described suspended hood 1 comprises exhaust duct 4, wind loop 5 and aspiration channel 6, described exhaust duct 4 is installed on the support 2, and the bottom of exhaust duct 4 is inserted into the top of ventilation fan retention tower 3, the top of described exhaust duct 4 is connected with wind loop 5 by flange, the inside of exhaust duct 4 is provided with central dividing plate 7, the both sides of exhaust duct 4 are provided with an aspiration channel 6, and the inside of described aspiration channel 6 is provided with deflector 10.
Laterally and on the vertical direction be provided with reinforcing rib 8 around the described exhaust duct 4.
Be provided with airtight curtain 9 on the circumference of described exhaust duct 4 and fan room retention tower 3 junctions.
When the utility model specifically uses, two suspended hoods 1 are installed in respectively on the ventilation fan retention tower 3 by support 2, support 2 adopts steel structure support, support 2 supports the top that fan room 11 is installed, the exhaust duct 4 of two suspended hoods 1 is inserted into respectively the top of ventilation fan retention tower 3, and the circumference of exhaust duct 4 and ventilation fan retention tower 3 junctions is equipped with airtight curtain 9, guarantee sealing, the top of exhaust duct 4 is connected with existing weary wind oxidation unit, the both sides of exhaust duct 4 are provided with an aspiration channel 6, are provided with deflector 10 in the aspiration channel 6, and deflector 10 is tilted to, the lower end is welded on the bottom of aspiration channel 6, the weary wind that ventilation fan retention tower 3 is discharged enters weary wind oxidation unit burning by exhaust duct 4, because the motion of weary wind produces negative pressure, aspiration channel 6 constantly imports air in weary wind, air is by deflector 10, the direction of motion along weary wind enters weary wind oxidation unit, and weary wind mixed combustion, and reinforcing rib 8 is set around the exhaust duct 4, guarantee that exhaust duct 4 has some strength, be difficult for toppling over.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
