Split type impeller

Abstract

The invention provides a split type impeller. The root of a blade (3) is provided with an installation column (4) used for connecting a first hub (1) with a second hub (2), a first convex part (41) is arranged on an exterior cylindrical surface of the installation column in a protruding mode, the positions, corresponding to the first convex part, of a first fixing groove (11) and a second fixing groove (12) are set into groove face structures matched with the first convex part, an inner cavity of the installation column is detachably and internally provided with an adjusting block (5), and a guide groove (6) and a second convex part (7) are arranged between the adjusting block and the first fixing groove or the second fixing groove and matched in a sliding mode in the direction perpendicular to the axis of the installation column. The split type impeller is simple in structure, the design and production process of a mold is simplified, the installation angle of the blade can be changed by replacing the second fixing groove and arranging adjusting blocks different in position, new adjusting blocks need to be designed and manufactured, the whole impeller does not need to be replaced, the process is simple and convenient and the cost is saved.

Description

technical field [0001] The invention relates to a fan impeller, in particular to a split impeller. Background technique [0002] Fan impellers are widely used in hydraulic cooling, heat exchange systems, ventilation systems and other fields. Most of the existing fan impellers are integral structures. However, fan impellers generally have a large number of blades. It is difficult to make molds for integral impellers, and the cost also increases. In addition, in the existing impellers, the installation angle of the blades is mostly non-adjustable, and it is impossible to change the blade angle according to the actual application needs (such as air volume and wind pressure). Therefore, it needs to be redesigned and manufactured according to different application needs. The impeller further increases the cost. Therefore, a solution is needed in the prior art to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a split i...
