Abstract
A connecting device of a coal mine underground local fan with an air drum is used in local coal mine underground ventilation and avoids air leakage and disjointing during connection of a local fan with an air drum. The connecting device comprises a glass fiber reinforced plastic flange (1), a glass fiber reinforced plastic reducing sub (2), an inner rubber pressure bearing air drum (3), an outer rubber connecting air drum (4) and an end ring (5). The inner rubber pressure bearing air drum (3) is sleeved inside the outer rubber connecting air drum (4), after a small opening end of the glass fiber reinforced plastic reducing sub (2) is connected with the inner rubber pressure bearing air drum (3), a large opening end of the glass fiber reinforced plastic reducing sub (2) is connected with the glass fiber reinforced plastic flange (1), and the end ring (5) is sleeved at the outer end of the bottom of the outer rubber connecting air drum (4). The connecting device of a coal mine underground local fan with an air drum has the advantages of flame resistance, electrostatic resistance, small air resistance, high strength, compact integral structure, simple manufacturing, easy installation, small maintenance frequency, high air pressure resistance, convenient utilization, durability, long service life and the like.
Description
Technical field
Portable blower and air duct linkage are used for the local ventilation under coal mine under the coal mine, stop to leak out and discrepancy in portable blower and the air duct connection procedure.
Background technology
Portable blower and the connected mode of being connected of air duct always using iron wire to tie up air duct under the present coal mine, because imprecision in portable blower hard transition segment and the soft air duct connection procedure, cause portable blower high pressure position to leak out, reduced the effective wind rate of portable blower, because air duct and transition segment are not firm because of fixing yet, cause the direct discrepancy of air duct and portable blower, increase the difficulty on the partial Ventilation Management.
Summary of the invention
The technical problems to be solved in the utility model is: overcome leaking out and discrepancy in portable blower that prior art exists and the air duct connection procedure, design portable blower and air duct linkage under a kind of coal mine of the effective wind rate that can improve booster.
The technical scheme that its technical problem that solves the utility model adopts is: portable blower and air duct linkage under this coal mine, it is characterized in that: comprise glass fiber reinforced plastic male flange, glass fiber reinforced plastic reducing pipe nipple, interior colloid pressure-bearing air duct, ectoglia connect air duct and end circle, interior colloid pressure-bearing air duct is sleeved on ectoglia and connects in the air duct, glass fiber reinforced plastic reducing pipe nipple osculum end is with after interior colloid pressure-bearing air duct is connected, glass fiber reinforced plastic reducing pipe nipple big opening end connects the glass fiber reinforced plastic male flange, and the end snare is contained in ectoglia and connects outer end, air duct bottom.
Interior colloid pressure-bearing air duct is connected air duct with ectoglia be the seamless connection of soft air duct.
Compared with prior art, the beneficial effect that portable blower and air duct linkage are had under the coal mine of the present utility model is: portable blower and air duct linkage have substituted traditional connected mode of tying up air duct, adopt the heat treatment integral one-step molding technique, reach vertical no seam, have fire-retardant, antistatic, windage is little, intensity height, compact overall structure, make simple, the characteristics easy, that maintenance frequency is few are installed, and anti-blast is strong, and is easy to use, durable, advantages such as long service life.
It is on probation first that this linkage belongs in coal mine safety management, and result of use has reached intended purposes fully.This portable blower and air duct linkage are applied under the coal mine to stop to leak out and discrepancy in portable blower and the air duct connection procedure in the partial Ventilation Management, improve the effective wind rate of booster.
Description of drawings
Fig. 1 is the structural representation of portable blower and air duct linkage under the coal mine of the present utility model.
Wherein: colloid pressure-bearing air duct, 4 ectoglias connect air duct, 5, end circle in 1 glass fiber reinforced plastic male flange, the 2 glass fiber reinforced plastic reducing pipe nipples, 3.
The specific embodiment
Be described further below in conjunction with portable blower and air duct linkage under 1 pair of coal mine of the present utility model of accompanying drawing:
Portable blower and air duct linkage under this coal mine, by glass fiber reinforced plastic male flange 1, glass fiber reinforced plastic reducing pipe nipple 2, interior colloid pressure-bearing air duct 3, ectoglia connect air duct 4 and end circle 5 is formed, interior colloid pressure-bearing air duct 3 is sleeved on ectoglia and connects in the air duct 4, and interior colloid pressure-bearing air duct 3 is connected the seamless connection of air duct 4 for cast 196 unsaturated-resins with ectoglia.Glass fiber reinforced plastic reducing pipe nipple 2 osculum ends are connected with interior colloid pressure-bearing air duct 3, and glass fiber reinforced plastic reducing pipe nipple 2 big opening ends connect glass fiber reinforced plastic male flange 1, and end circle 5 is sleeved on ectoglia and connects outer end, air duct 4 bottom.
Be connected required size with air duct according to portable blower hard transition segment, make the skeleton of linkage, in skeleton, alternately lay glass fabric and air duct respectively, pour into a mould 196 unsaturated-resins, compression moulding with the iron plate of 3mm.
During use, portable blower can be connected with Φ 12mm screw with the glass fiber reinforced plastic male flange of air duct linkage, and be fixed on the portable blower air outlet noise damper.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
