Detailed Description
The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
A dust removal back-tilting cabinet type centrifugal fan is shown in figures 1-2 and comprises a cabinet body 1 which is arranged in a hollow mode, an air outlet pipe 2 which is communicated with and fixed to the cabinet body 1, a current collector 3 which is arranged inside the cabinet body 1, a transmission shaft 4 which is arranged inside the cabinet body 1, an impeller 5 which is arranged on the transmission shaft 4 in a sleeved mode, a motor 6 which is arranged at one end, far away from the impeller 5, of the transmission shaft 4, a first filter screen 7 which is arranged inside the cabinet body 1, a second filter screen 8 which is arranged inside the air outlet pipe 2, and a spiral piece type fairing 9 which is arranged at one end, far away from the cabinet body 1, of the air outlet pipe 2. Can play the effect of the kinetic energy of circling round that weakens fan export air current through spiral piece formula radome fairing 9, because the loss of pressure of fan is directly proportional with the square of velocity of flow, so the speed of flow of air-out that weakens the fan through the kinetic energy of circling round that weakens fan export air current reduces the loss of pressure of the export air current of fan, thereby can improve the efficiency of fan, and can also carry out the water conservancy diversion through spiral piece formula radome fairing 9 to the air-out of fan and correct the processing, enlarge the air-out scope of tuber pipe 2.
In the present embodiment, the motor 6 is located outside the cabinet 1. The cabinet body 1 is characterized in that an installation plate 11 is fixedly welded on the outer wall of one side of the cabinet body 1, and the motor 6 is fixedly installed at the top of the installation plate 11.
