Detailed Description
Fig. 1 shows the side direction section structure schematic diagram of general lampblack absorber fan, and fig. 2 shows the side direction section structure schematic diagram of an embodiment of the utility model discloses a lampblack absorber fan.
The structure of the wind power generation device is basically the same as that of the wind power generation device shown in the figures 1 and 2, the wind power generation device is provided with a volute wind channel 3, an air outlet is arranged on the volute wind channel, an air inlet hole is arranged in the middle of the front side of the volute wind channel, an air inlet ring 5 is arranged on the device, a motor mounting hole 3.1 is arranged in the middle of the rear side of the volute wind channel, a motor frame 2 is arranged on the device, a motor 1 is fixed on the motor frame 2 through a screw 7, in order to facilitate the long-time wind impeller 4 and a motor shaft to be rusted, the motor fastening screw 7 is detached, a through hole 4-1 is formed in a disc of the wind impeller 4, a shaft sleeve is arranged in the middle of the wind.
Fig. 1 and 2 differ in that:
in the figure 1, air enters the front and the back of a fan of a common smoke machine, the air enters the front of the fan and enters the middle of an impeller through a conventional fan air inlet B, the air enters the rear of the fan C and flows through the surface of a motor, passes through a motor mounting hole 3.1 and a through hole 4-1 on a disc of the impeller 4 and enters the middle of the impeller, the original purpose is to radiate the motor, but the air enters the C and contains grease particles, so that oil stains are agglomerated on the surface of the motor and dried, the thickness of an oil stain layer is increased after the year, and the temperature rise is increased to.
A gap is formed between the rear wall of the volute air channel 3 and the rear web of the wind impeller 4, a gap is also formed between the wind inlet ring 5 and the front web of the wind impeller 4, and air flow passes through the gap to flow, but no blade is arranged on the wind impeller, the wind inlet smoke cannot be driven to rotate, and no centrifugal force exists, so the wind inlet smoke cannot flow outwards from the two gaps. On the contrary, the wind pressure at the periphery of the wind impeller 4 is higher than that at the center, and the inward flowing airflows F and E are formed, which reduces the exhaust air volume to lower the fan efficiency. The air flows F and E rotate, keep momentum moment conservation and are in a rotating state when flowing inwards, and generate centrifugal force to resist the inward flow, so that the inward flow of the air flows F and E is less, and the air flows F and E are increased along with the increase of air outlet resistance. The flue gas at the periphery of the wind impeller is that the inlet air flue gas is impacted by the blades of the wind impeller and centrifugally purified by high-speed rotation, so that the oil content of the air flows F and E is much less.
Fig. 2, the utility model discloses a lampblack absorber fan has installed an grease proofing fin 9 on the shell amplitude disc of motor 1 to compress tightly with arc rubber pad 8A, make the shell amplitude disc of motor 1 conduct heat to grease proofing fin 9 and play the radiating action, cut off back air inlet C simultaneously, do not make it flow through the motor surface and long-pending oil, only preceding air inlet B, and preceding analyzed air current B is through-hole 4-1 on the amplitude disc that can not pass through impeller 4 and flow to the motor surface. Therefore, although the motor does not have the heat dissipation of the air intake flow, the heat dissipation plate 9 with the surface area equivalent to that of the motor is added, namely the heat dissipation area is doubled, the air intake flow C is changed into the high-speed rotating air flow F to flow on the heat dissipation plate and the surface of the motor for heat dissipation after the air intake flow C does not exist, the analyzed air flow F has much less grease content, so that the heat dissipation effect is enhanced, the accumulation amount of the grease on the surface of the motor is greatly reduced, the service life of the motor can be greatly prolonged, and the motor fixing screw 7 can be still dismounted from the through hole 4-1 on the disc.
In addition, in fig. 1, the leather pad 8 between the original motor 1 and the motor frame 2 only needs to be in a round sleeve shape, the leather pad is changed into an arc-shaped rubber pad 8A in fig. 2, fig. 3 is a rear view a in fig. 2, the arc-shaped rubber pad 8A is sectioned, the appearance is in an arc-shaped strip shape, two ends of the arc-shaped rubber pad are provided with through screws, and the arc-shaped rubber pad is padded between the oil-proof radiating fin 9 and the motor frame 2, so that the oil-proof radiating fin 9 is in close contact with the shell.
Fig. 4 is a plane shape of the oil-proof radiating fin 9, and a notch 9-1 is formed at the inner hole to avoid the grounding wire of the motor.
Fig. 5 shows that the oil-proof fin 9 is made into a concave-convex disk shape to increase rigidity, and a thinner material can be used.
