Abstract
The utility model belongs to the technical field of cooling tower fans, and particularly relates to a novel cooling tower fan, which comprises a casing, a shaft, an impeller, blades, two water inlet ducts and a guide board set. The shaft with one end extending out of the casing is movably mounted in the casing, the impeller is mounted on an inner shaft of the casing, the blades are mounted at the end, extending out of the casing, of the shaft, the two water inlet ducts communicated with an inner cavity of the casing form a certain included angle, and the guide board set is mounted at a water inlet on the inner wall of a turbine.
Description
Technical field
The utility model belongs to the technical field of blower fan of cooling tower.
Background technique
At present, most of blower fan of cooling tower is all forced to drive by motor and is rotated, motor forces blower fan to rotate the sizable electric energy of consumption that will do nothing on the one hand, increase mechanicalness noise, simultaneously, can not be utilized and waste owing to provide the recycle pump of power to have about 25 ~ 30% lift energy more than needed for recirculated cooling water in the cooling tower, greatly wasted the energy, in whole people's energy saving, enter today of low-carbon (LC) life, no matter be, still be that this all is a greatly waste to social resources to reducing production costs.The patent No. is 200920307711.8 patent, the novel blower fan of cooling tower of a kind of axial flow is disclosed, though not needing forced motor to drive fan blade, the novel blower fan of cooling tower of the technological scheme of this patent disclosure do not rotate, but the runner of this technology must be a scroll casing shape, and has only an inlet channel, also to slow down to fan blade with speed reducer, the size and the material consumption of equipment have promptly been increased, and speed reducer is difficult to accomplish axle with one heart, and the equipment that makes is easy to generate vibration, reduces the working life of equipment, the resistance of single water channel aqueduct is big simultaneously, water also causes device damage easily to the impact force imbalance of turbine, reduces the working life of equipment.And the efficient that water can be converted into mechanical energy is lower.
Summary of the invention
Service life of equipment is short, noise big in order to overcome, water can be converted into the inefficient problem of mechanical energy, and the utility model provides that a kind of vibration equipment is little, noise is little, long service life, without consumed power, and the high novel blower fan of cooling tower of energy conversion efficiency.
This novel blower fan of cooling tower comprises housing, movable in housing the axle that an end stretches out housing is housed, and is contained in the impeller on the axle in the housing, is contained in shaft extension and goes out fan blade on the shell ends, the inlet channel of certain angle of twenty percent and housing inner chamber UNICOM; Be contained in one group of guide plate of water inlet on the turbine inwall.
As advancing an improvement to of the present utility model, inlet channel (6) cross section is trapezoidal.Two inlet channels at grade and between its two medial axis angle be acute angle.Blade (7) cross section of impeller (3) is the s type.
Beneficial effect: owing to have two inlet channels to intake simultaneously, and have the leaf cross-section of guide plate water conservancy diversion and impeller to be the s type, so the pulsating nature of turbine is littler, noise is lower, and the efficient that water can be converted into mechanical energy is higher, and little to the damage of turbine, rate of fault is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Figure 1 shows that the structural representation of facing of novel blower fan of cooling tower;
Figure 2 shows that the turbine structure schematic representation.
Embodiment
Novel blower fan of cooling tower as shown in the figure, comprise housing 1, the axle 2 that an end stretches out housing is equipped with in activity in housing 1, is contained in the impeller 3 on the axle 2 in the housing 1, be contained in axle 2 fan blades 4 that stretch out on housing 1 end, the inlet channel 6 of certain angle of twenty percent and housing 1 inner chamber UNICOM; Inlet channel (6) cross section is trapezoidal.Its medial axis and axle 2 vertical two inlet channels at grade and between two medial axis angle less than 180 degree.Be contained in one group of guide plate 7 of water inlet on the turbine inwall.One group of guide plate 7 is two, and guide plate 7 acutangulates with the feed water flow direction.
Claims (5)
1. novel blower fan of cooling tower, comprise housing (1), it is characterized in that the axle (2) that an end stretches out housing (1) is equipped with in activity in housing (1), be contained in the impeller (3) on the axle (2) in the housing (1), be contained in axle (2) and stretch out fan blade (4) on housing (1) end, the inlet channel (6) of certain angle of twenty percent and housing (1) inner chamber UNICOM; Be contained in one group of guide plate (7) of water inlet on the turbine inwall.
2. novel blower fan of cooling tower according to claim 1 is characterized in that inlet channel (6) cross section is trapezoidal.
