Description

Jet fan for cultivation

Technical Field

The utility model relates to the technical field of livestock breeding, in particular to a jet fan for breeding.

Background

As shown in fig. 1, when the ordinary axial flow fan is used as a fan for stirring and circulating heat in a poultry house, the wind direction at the air outlet of the fan is diffused all around seriously, and is easily blown onto poultry bodies, so that the poultry are cooled. And the air direction of the common axial flow fan is diffused all around, so that the air supply distance is short.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the conventional common axial flow fan, the utility model provides a jet flow fan for cultivation, which adopts the technical scheme that:

the jet fan for cultivation comprises an axial flow fan, wherein a flow guide cover is additionally arranged at the air outlet end of the axial flow fan, a flow guide pipe and a plurality of flow guide radial plates are arranged in the center of the flow guide cover, the flow guide radial plates are uniformly and radially distributed along the circumferential direction of the flow guide cover or the flow guide pipe, one end of each flow guide radial plate is fixedly connected with the inner wall of the flow guide cover, and the other end of each flow guide radial plate is fixedly connected with the outer wall of the flow guide pipe.

Compared with the prior art, the utility model utilizes the existing axial flow fan, reduces the peripheral diffusion of wind direction by additionally arranging the flow guide device, increases the middle wind speed, prolongs the air supply distance, and is suitable for the stirring circulation of the internal heat of the multilayer henhouse.

Detailed Description

Embodiment 1, as shown in the figure, a efflux fan for breed, including commercially available axial fan 1, install kuppe 2 additional at axial fan 1 air-out end, kuppe 2 center sets up a honeycomb duct 3, 8 water conservancy diversion radials 4, and the water conservancy diversion radials evenly radially distributes along honeycomb duct 3 circumference, and the one end of water conservancy diversion radials and the inner wall welding of kuppe 2, the other end and the outer wall welding of honeycomb duct 3. As shown in fig. 3, the inner end of the air guide sleeve 2 fits the shape of the air outlet end of the axial flow fan 1 and is inserted into the air outlet end of the axial flow fan 1 and fixedly connected by 12 socket head cap screws 5. The length of the air guide sleeve 2 is more than or equal to that of the axial flow fan 1, the longer the length is, the better the effect is, but the length can not be infinitely prolonged, and the defects of insufficient installation space, increase of manufacturing cost, loss of air pressure and increase of energy consumption can be caused. The length of the draft tube 3 is equal to that of the draft hood 2. The length of the flow guiding web plate is equal to the length of the flow guiding cover 2. The axis of the flow guide pipe 3 coincides with the axis of the axial flow fan 1.

Embodiment 2 is otherwise the same as embodiment 1 except that the inner diameter of the nacelle 2 is gradually reduced from the end close to the axial flow fan 1 to the other end, and accordingly, the height of the shroud is also gradually reduced from the end close to the axial flow fan 1 to the other end. But the reduction amplitude cannot be too large, and the loss of wind pressure and the increase of energy consumption are also caused. In general, the ratio of the diameter difference between the two ends to the length thereof is less than 2%, and the tapering rate adopted in the embodiment is 1%.

Practice proves that the technical scheme of the utility model has low cost and simple and convenient modification, the rotating wind at the air outlet changes direction after the modification, changes the wind direction into the direction along the axis, can greatly reduce the diffusion of the fan, reduces the diffusion radius, can blow out a longer distance, and is very suitable for being applied to multilayer poultry houses.

The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; those skilled in the art can make many possible variations or modifications to the utility model using the methods and techniques disclosed above, or to modify equivalent embodiments without departing from the scope of the utility model. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention.
