Abstract
The utility model belongs to cooling tower technical field, discloses a double force high-efficiency whirl rotator for a cooling tower, and is characterized in that the whirl rotator comprises a box body with a water inlet, a water return opening, and a top cover; fan blades are arranged in the box body; flow deflectors are arranged along the outer edges of the fan blades in the box body; and thefan blades are obliquely arranged on a fan disc connected with the top cover. In the utility model, the fan blades are obliquely arranged on a fan disc connected with the top cover, so that the size of the fan blades is greatly reduced. After entering the box body from the water inlet, water flushes towards the fan blades through the gaps among the flow deflectors. Because the size of the fan blades is relatively small, and water falls down under the stop of the fan disc and then flushes back towards the fan blades, the water flow can be impacted twice, impact exerted on the fan blades becomeslarger, the rotation speed of fan blades is greatly improved, the refrigerating effect of the cooling tower is improved, water power is fully used, requirement for water pressure is low, and adaptation range is greatly widened.
Description
Technical field
The utility model belongs to the cooling tower technical field, relates in particular to a kind of pair of power high-efficiency cooling tower eddy flow rot.
Background technology
In the chemical plant, place such as paper mill, power plant, the application of cooling tower is more and more widely.Drive the cool rotary device that blower fan rotates on the current cooling tower, comprise the casing that has water inlet and water return outlet, be provided with flabellum in the casing.The cool rotary device of this structure, the eccentric design of its flabellum, difficulty of processing is big.And water can produce certain adverse current after entering casing, makes and the suffered impulsive force inequality of each flabellum causes the flabellum rotating speed lower.The patent No. is 200820076144.5, patent name provides a kind of rot for the patent document of " cooling tower eddy flow rot ", some arc flow deflectors evenly are set along the flabellum outer in casing, the arc flow deflector is to the bending of water inlet direction, so just equals to be provided with in the flabellum outer swirl-flow devices.Water rushes at flabellum by the gap between flow deflector after entering casing by water inlet, and the influence of adverse current has been avoided in the suffered impulsive force equilibrium of each flabellum, thereby can improve the flabellum rotating speed greatly, makes the cooling tower refrigeration improve.The rot of this structure in addition, flabellum, flow deflector and casing can concentric design, thereby reduced manufacture difficulty, make processing simple, are easy to install.But the flabellum of this rot vertically is provided with, and the flabellum volume is bigger, and water is rushed at directly to fall by water return outlet behind the flabellum by the gap between flow deflector and flows away, and waterpower is also underused.
The utility model content
The technical problems to be solved in the utility model just provides a kind of two power high-efficiency cooling tower eddy flow rots that make full use of waterpower.
For solving the problems of the technologies described above, the technical scheme that the two power high-efficiency cooling tower eddy flow rots of the utility model adopt is: comprise the casing that has water inlet, water return outlet and top cover, be provided with flabellum in the casing, be provided with flow deflector along the flabellum outer in the casing, described flabellum is obliquely installed on the fan dish that is connected with top cover.
Its additional technical feature is: described flabellum is an arc; Described flabellum and horizontal plane angle at 45; The top of described flabellum has the limit groove; Be provided with reinforcement in the described fan dish; Described flow deflector is the arc that evenly is provided with; Described casing is provided with second water inlet.
Provided by the utility model pair of power high-efficiency cooling tower eddy flow rot compared with prior art, flabellum is obliquely installed on the fan dish that is connected with top cover, the flabellum volume reduces greatly.After water enters casing by water inlet, rush at flabellum by the gap between flow deflector, because the flabellum volume is less, water is stopped by the fan dish to fall behind the flabellum that recoils again down, makes the current secondary pulse one time, the suffered impulsive force of flabellum strengthens, thereby can improve the flabellum rotating speed greatly, make the cooling tower refrigeration improve, thereby made full use of waterpower, hydraulic pressure requires little, and accommodation increases greatly.And flabellum is an arc, and flabellum and horizontal plane angle at 45 makes flabellum stressed better.The top of flabellum has the limit groove, is easy to install, and not influenced by the interior burr of casing.Be provided with reinforcement in the fan dish, structure is firmer.Casing is provided with second water inlet, when summer, weather was hot, by water inlet and the water filling in casing simultaneously of second water inlet, makes inflow increase with water pump, more can improve refrigeration greatly.

The specific embodiment
The structure and the specific embodiment of the two power high-efficiency cooling tower eddy flow rots that the utility model provided below in conjunction with accompanying drawing are described further.
As shown in Figure 1, the two power high-efficiency cooling tower eddy flow rots of the utility model comprise casing 1, and casing 1 has water inlet 2, water return outlet 3 and top cover 4.As shown in Figure 2, be provided with flabellum 5 in the casing 1, flabellum 5 is arranged on the fan dish 6, is provided with reinforcement 7 in the fan dish 6, is provided with flow deflector 8 along flabellum 5 outers in the casing 1.As shown in Figure 3, casing 1 has water inlet 2, water return outlet 3, and casing 1 inwall evenly is provided with arc flow deflector 8.As shown in Figure 4, flabellum 5 be obliquely installed with fan dish 6 that top cover 4 is connected on, flabellum 5 is an arc, flabellum 5 and horizontal plane angle at 45.As shown in Figure 5, the top of flabellum 5 has limit groove 9, is provided with reinforcement 7 in the fan dish 6.
During use, after water enters casing 1 by water inlet 2, gap by 8 of flow deflectors rushes at flabellum 5, because flabellum 5 volumes are less, water is stopped by fan dish 6 to fall behind the flabellum 5 that recoils again down, makes the current secondary pulse one time, flabellum 5 suffered impulsive forces strengthen, thereby can improve flabellum 5 rotating speeds greatly, make the cooling tower refrigeration improve, thereby made full use of waterpower.And flabellum 5 be arc and with horizontal plane angle at 45, make flabellum 5 stressed better.The top of flabellum 5 has limit groove 9, is easy to install, and not influenced by casing 1 interior burr.Be provided with reinforcement 7 in the fan dish 6, structure is firmer.
The two power high-efficiency cooling tower eddy flow rots of the utility model are not limited only to the said structure form, on casing, also second water inlet can be set, when summer, weather was hot, with water pump by the water filling in casing simultaneously of water inlet and second water inlet, make inflow increase, more can improve refrigeration greatly.
