Abstract
The utility model discloses a fan for a cooling tower. The fan comprises a shell, and an impeller and a transmission shaft are arranged in the shell. The fan is characterized in that a motor is arranged outside the shell and is linked with the impeller through the transmission shaft, a water inlet pipe is arranged on one side of the impeller, a water outlet pipe is arranged on the other side of the impeller, blades are arranged at the upper end of the transmission shaft, a certain included angle is formed between the water inlet pipe and the water outlet pipe, and an S-shaped splitter is arranged on the impeller. The fan has the advantages that the fan is reasonable in structural design, simple to operate and stable in running, a certain angle is formed between the water inlet pipe and the water outlet pipe, the water inlet pipe and the water outlet pipe are driven by the impeller, resistance is low when water enters the fan, transmission speed is high, working efficiency is improved, two sides of each blade are progressively increased from top to bottom in design, the top end of each blade is semicircular, noise can be reduced in the operation process, a buffer function is achieved, water energy is more efficiently converted into mechanical energy, and the S-shaped splitter arranged on the impeller is convenient to mount and maintain.
Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of used for cooling tower blower fan.
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, enter today of low-carbon (LC) life, no matter be to reducing production costs, still this all is a greatly waste to social resources, the equipment that makes is easy to generate vibration, in the working life of reduction equipment, the resistance of single water channel aqueduct is big simultaneously, and water is to the impact force imbalance of impeller, also cause device damage easily, reduce the working life of equipment.And the efficient that water can be converted into mechanical energy is lower.Therefore, for addressing the above problem, the spy provides a kind of new technological scheme.
The model utility content
The purpose of this utility model provides a kind of used for cooling tower blower fan.
The technical solution adopted in the utility model is:
A kind of used for cooling tower blower fan, comprise housing, be provided with impeller and transmission shaft in the described housing, described outside is provided with motor, and described motor is by transmission shaft and impeller interlock, described impeller one side is provided with intake pipe, described impeller opposite side is provided with outlet pipe, and described transmission shaft upper end is provided with blade, forms certain angle between described intake pipe and the outlet pipe, described impeller is provided with shunt, the S type that is shaped as of described shunt.
Described blade both sides from top to bottom increase progressively, and blade tip is semicircle shape.
Angle is the obtuse angle.
Described intake pipe is communicated with by impeller with outlet pipe.
The utility model has the advantages that: reasonable in design, simple to operate, stable, form several angle between outlet pipe and the intake pipe and drive by impeller, resistance is little during water inlet, transmission speed is fast, has improved working efficiency, and blade is designed to both sides and from top to bottom increases progressively, the top is the shape of semicircle shape, can reduce noise in operation, play the effect of buffering, the efficient that water can be converted into mechanical energy is higher, shunt on the impeller adopts the S shape, damage to impeller is little, and rate of fault is low, and is convenient for installation and maintenance.
