Description
Technical field
The utility model is related to a kind of cooling tower, particularly a kind of cooling tower for preventing that fan blade from coming off.
Background technology
Cooling tower (The cooling tower) is, as circulating coolant, heat dissipation to be absorbed from a system with water
Into air, to reduce the device of water temperature；It is carried out cold and hot exchange and produces steam after being contacted using water with air flow, steam is waved
Hair band walks heat and reaches the principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer to disperse what is produced in industrial or refrigeration air-conditioner
Waste heat reduces the evaporating radiator of water temperature, and to ensure the normal operation of system, device is generally tubbiness, therefore named for cooling
Tower.During cooling tower works, the blower fan work at the top of cooling tower allows air to laterally enter cooling tower from cooling tower
Interior, air realizes heat exchange with flowing through after the water body of inserts is fully contacted, and is discharged eventually through air outlet.Due to cooling tower
Blower fan needs the operating and stopping repeated, therefore the blade of blower fan can bear larger centrifugal force, if the connecting shaft of blade with
Connection between the wheel hub of blower fan is likely to occur the situation that blade departs from wheel hub built on the sand, then, and in the process of high-speed rotation
In there is above mentioned problem, then be likely to result in great destruction, there is larger potential safety hazard.In order to prevent connecting shaft and wheel hub
Separation, the relatively large termination of a diameter traditionally can be all set in the end of connecting shaft, is so accomplished by being cut using metal
Bits processing technology is operated to connecting shaft, causes long processing time, and cost is high.
The content of the invention
The utility model is that design is ingeniously in order to solve the above-mentioned deficiency present in prior art, propose that one kind is simple in construction
It is wonderful, it is with low cost, and can effectively prevent the cooling tower that fan blade comes off from wheel hub.
Technical solution of the present utility model is：A kind of cooling tower for preventing that fan blade from coming off, including cooling tower
Housing 1, it is characterised in that：It is provided with air channel 2, the cooling tower shell 1 on the top of air channel 2 and offers out in cooling tower shell 1
Air port, is provided with blower fan 3 at air outlet, inserts 4 is additionally provided with the side cooling tower shell 1 of air channel 2, in inserts 4
Top be provided with the first tank 5, multiple blades that the lower section of inserts 4 is provided with the second tank 6, described blower fan 3 lead to
Cross connecting shaft 7 to be fixedly connected with the wheel hub 8 of blower fan, one end of connecting shaft 7 is fixedly connected on wheel hub 8 by gland 9, described
Gland 9 is fixedly connected by multiple fasteners with wheel hub 8, and the one end matched in connecting shaft 7 and gland 9 offers annular groove 10,
And axially vertical, the sunk part matching of the bolt and annular groove 10, i.e., two of the plane where annular groove 10 and connecting shaft 7
The diameter for being smaller than connecting shaft 7 of opposite side between individual paired bolt.
Described fastener is bolt or U-bolt.
The utility model compared with the existing technology, has the following advantages that：
This kind of structure type prevents cooling tower that fan blade comes off, and its is simple in construction, ingenious in design, and layout is closed
Reason, the end of its connecting shaft between blade and wheel hub opens up out two annular grooves being parallel to each other, and is equipped with fixed spiral shell
Bolt, allows bolt card in annular groove, so as to prevent connecting shaft from occurring axial float, to ensure to connect in wheel hub high-speed rotation
Axle and blade and wheel hub are stably connected with, and in this configuration, bolt is with fixed connection shaft and prevents what connecting shaft from coming off
Dual-use function, can greatly be reduced process time and manufacturing cost, and the present embodiment only need to traditional cooling tower base
Being improved on plinth to obtain, therefore its improvement cost is cheap, be particularly suitable for popularization and application in the art, before its market
Scape is very wide.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is structural representation of the wheel hub with being connected shaft portion in the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2：One kind can prevent wind
Cooling tower shell 1 based on the cooling tower of machine leaf abscission, including one, is provided with air channel 2 in cooling tower shell 1,
Air outlet is offered on the cooling tower shell 1 on the top of air channel 2, blower fan 3 is provided with air outlet, in the side cooling tower of air channel 2
Inserts 4 is additionally provided with housing 1, the first tank 5 is provided with the top of inserts 4, the lower section of inserts 4 is provided with second
Tank 6,
Multiple blades are connected with by multiple connecting shafts 7 on the wheel hub 8 of blower fan 3, one end of the connecting shaft 7 passes through pressure
Lid 9 is fixedly connected with wheel hub 8, and gland 9 is connected by four bolts with wheel hub 8, one matched in connecting shaft 7 and gland 9
End opens up annular groove 10, and the axis of the plane and connecting shaft 7 at this place of annular groove 10 is mutually perpendicular to, and above-mentioned spiral shell
The sunk part of bolt and annular groove 10 matches, i.e., bolt card is in annular groove 10, in this configuration, two paired bolts
Between the spacing of relative side be less than the diameter of connecting shaft 7.
The course of work for preventing cooling tower that fan blade comes off of the utility model embodiment is as follows：Blower fan 3 starts,
Cooling tower shell 1 is allowed to be internally formed negative pressure, cold air enters at air channel 2 from the lateral entrance of cooling tower shell 1, in the process
Cooling water heat is absorbed, and hot-air is discharged eventually through air outlet；Water in tank is constantly flowed downwardly on cooling segment,
Due to the presence of cellular inserts 4, the flow velocity of water can be substantially reduced, the contact area of water and hot-air, Jin Erti is improved
High heat exchanger effectiveness；Cooling water is passed through after inserts 4, is finally pooled in the second tank 6, and in the presence of water circulation system
Come back in the first tank 5 above, in the presence of deadweight, the water body in the first tank 5 is constantly flowed downwardly into
In inserts 4, circulated；
During blower fan work, motor driving wheel hub 8 is rotated, and drives blade to rotate to allow the cooling tower shell 1 of air channel 2
Interior generation negative pressure；Due to being connected with bolt in the annular groove 10 of the end of connecting shaft 7, these bolts will be connected not only by gland
Axle 7 is fixed on wheel hub 8, simultaneously because the spacing of side relative between two paired bolts is less than the straight of connecting shaft 7
Footpath, therefore these bolts limit the free degree on the axial direction of connecting shaft 7, i.e., can prevent connecting shaft 7 from occurring axial float, and then
Ensure that connecting shaft 7 will not come off together with blade thereon from wheel hub 8 when wheel hub 8 is rotated.
