Embodiment Construction

[0015] Such as figure 1 As shown, it includes a fan blade 2, a blade bottom plate 4, a transmission shaft 15, a casing 21 and a drive motor 16, and is characterized in that: the fan blade 2 and the blade bottom plate 4 are movably connected, and there is a T-shaped inner circle of the blade bottom plate 4. Slot 9, 1. The T-shaped groove 9 is compatible with the T-shaped structure at the top of the fan blade 4. Such a structure can be set to fix the front end of the fan blade 2, and it is also very convenient when dismounting. The fan blade 2 The blade fixing plate 8 is fixed at the end, and the blade fixing plate 8 is fixedly connected with the blade bottom plate 8 by bolts, so as to better ensure the stability of the fan blade 2 and prevent it from falling during operation. The blade bottom plate 8 is movably connected to the transmission shaft 15 , the transmission shaft 15 is fixedly connected to the drive motor 16 , and the drive motor 16 is fixedly connected to the drive ...

Abstract

The invention relates to a detachable centrifugal fan which includes fan blades, a blade bottom plate, a transmission shaft, a machine case and a driving motor. The detachable centrifugal fan is characterized in that the fan blades and the blade bottom plate are movably connected, a T-shaped groove is formed in an inner ring of the blade bottom plate, the T-shaped groove is matched with a T-shapedstructure at the top ends of the fan blades, a blade fixing plate is fixed at the tail ends of the fan blades, the blade fixing plate is fixedly connected to the blade bottom plate through bolts, theblade bottom plate and the transmission shaft are movably connected, and the transmission shaft and the drive motor are fixedly connected. Compared with the prior art, the detachable centrifugal fanincreases the pressure in the fan by reducing the contact surface between an air opening and outside air, the blades on the centrifugal fan can be detached so that cleaning is facilitated, and a device for filtering liquid impurities in the air is also arranged on the basis.

Description

technical field [0001] The invention relates to the field of centrifugal fans, in particular to a detachable centrifugal fan. Background technique [0002] At present, there are various structures of ventilators. In order to obtain low flow and high wind pressure, traditional fans usually use the method of intercepting or venting a part of the air volume, but this method is obviously a waste of electrical energy. [0003] The State Intellectual Property Office of the People's Republic of China has announced a utility model related to centrifugal fans. The authorized public number of this utility model is: CN 20745384 U. It includes a frame, one side of the frame is connected with a vertically arranged volute, the frame is fixedly connected with a drive motor, the output shaft of the drive motor is inserted into the volute along the axial direction of the volute, and a fixed connection is arranged in the volute For the centrifugal impeller on the output shaft, the end surfac...
