Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a wind energy flow guide device for a single-stage centrifugal blower. Background Art

[0002] Single-stage high-pressure centrifugal blowers mainly provide compressed air to the oxygen-consuming area of ​​the sewage treatment process and are key equipment in sewage treatment plants. However, some blower high-pressure motors have design defects, resulting in the lack of auxiliary heat dissipation devices for the load-end bearings. During summer operation, this will cause an over-temperature warning at the load-end bearings, which will cause the blower to stop running.

[0003] The all-round heat dissipation of a single-stage high-pressure centrifugal blower is an urgent problem to be solved. For example, a Chinese patent with the authorization announcement number CN219865617U discloses a heat dissipation structure for a centrifugal fan, which is convenient for fixing the first arc plate and the second arc plate to the rear side of the drive motor by setting a rear baffle, and the rear side of the rear baffle is convenient for sealing by setting a filter screen and a cover plate, so as to reduce the dust from entering when the centrifugal blower body is not in use. When the drive motor needs to be cooled, the cover plate can be unscrewed for heat dissipation. The above patent is suitable for smaller centrifugal fans, and cannot effectively dissipate heat at the output end of a single-stage high-pressure centrifugal blower. Utility Model Content

[0007] Preferably, the flow guide device is symmetrically arranged on both sides of the left end of the motor, the vertical line of the semicircular cylinder is perpendicular to the ground, and the opening of the semicircular cylinder is directly opposite to the output end of the motor.

[0008] Preferably, the two support columns of the U-shaped bracket are liftable structures, the support columns include support tubes and movable columns, and fastening screws are provided on the support columns.

[0019] Example

[0020] like Figure 1-2 As shown, this embodiment provides a single-stage centrifugal blower wind energy guide device, including a motor 1, square plates 2 are provided on both sides of the motor 1, a semicircular cylinder 3 is connected to the left side of the square plate 2, a U-shaped bracket 4 is provided at the lower end of the square plate 2, and the bottom of the U-shaped bracket 4 is connected to the fixed bracket 5.

[0021] Preferably, a cooling fan 6 is provided on the right side of the motor 1, and the cooling fan 6 faces the air guide device.

[0022] Preferably, the guide device is symmetrically arranged on both sides of the left end of the motor 1, the vertical line of the semicircular cylinder 3 is perpendicular to the ground, and the opening of the semicircular cylinder 3 is directly opposite to the output end of the motor 1. By providing the semicircular cylinder 3, the wind blown by the cooling fan 6 can be diverted and the output end of the single-stage centrifugal blower can be cooled.

[0023] Preferably, the two support columns of the U-shaped bracket 4 are liftable structures, the support columns include a support tube 41 and a movable column, and fastening screws are provided on the support columns. By setting the U-shaped bracket 4 as a liftable structure, the guide device can be adjusted in height as needed, and can adapt to different working environments and equipment requirements.

[0024] Preferably, the flow guide device is arranged on both sides of the motor and the distance from the motor is 200 mm.

[0025] Working principle:

[0026] Square plates 2 are installed on both sides of the motor 1, which not only play a role of fixing and supporting, but also ensure the structural stability of the device. On the left side of the square plate 2, a semicircular cylinder 3 is designed, which guides the path of the wind.

[0027] When the motor 1 is running, the wind energy and heat generated by it need to be dissipated and cooled through appropriate means to ensure the normal operation and extend the service life of the motor 1. At this time, the cooling fan 6 on the right side of the motor 1 starts to work, and the wind flow generated by the cooling fan 6 will blow towards the direction of the air guide device.

[0028] The guide devices are symmetrically arranged on both sides of the left end of the motor 1 to ensure that the wind flow can be evenly distributed to the output end of the motor 1. The vertical line of the semicircular cylinder 3 is perpendicular to the ground, and its opening is just aligned with the output end of the motor 1. This design can accurately guide and turn the wind blown by the cooling fan 6 to directly cool the output end of the single-stage centrifugal blower.

[0029] In order to increase the adaptability and flexibility of the device, the two support columns of the U-shaped bracket 4 are designed as a liftable structure. This structure consists of a support tube 41 and a movable column 42. The user can adjust the position of the movable column 42 in the support tube 41 and fix it with the fastening screws on the support column to achieve height adjustment of the guide device. This design enables the device to adapt to different working environments and equipment requirements, ensuring that the path and effect of the wind flow are always in the best state.
