Abstract
The utility model relates to the field of ventilating devices. A centrifuge impeller comprises a metal front ring, a metal chassis and a plurality of metal blades, wherein the plurality of metal blades are fixed between the metal front ring and the metal chassis, and turnups which protrude downwards are arranged on the end portion of the outer side of the bottom face of the metal chassis. The centrifuge impeller has the advantages of being novel in structure and high in intensity of the metal chassis.
Description
Technical field
The utility model relates to the ventilation equipment field, relates in particular to a kind of metal centrifugal impeller.
Background technique
Metal centrifugal impeller is ventilation equipment field product commonly used, its structure comprises circle, metal chassis before the metal and is fixed between the two a plurality of metal blades, its metal chassis external lateral portion of existing metal centrifugal impeller is burnishing surface, and the deficiency of its existence is that metal chassis intensity is low.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to solve existing centrifugal impeller, provides a kind of novel structure, the centrifugal impeller that metal chassis intensity is high.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of centrifugal impeller comprises circle, metal chassis before the metal and is fixed between the two a plurality of metal blades that the outboard end of metal chassis bottom surface is provided with the flange of downward protrusion.
Adopted the centrifugal impeller of above-mentioned technological scheme, the outboard end of metal chassis bottom surface is provided with the flange of downward protrusion.The advantage of this centrifugal impeller is novel structure, and the intensity of metal chassis is high.
Description of drawings
Fig. 1: the utility model embodiment's perspective view.
Fig. 2: the utility model embodiment's cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2 embodiment of the present utility model is made a detailed explanation.
Centrifugal impeller as depicted in figs. 1 and 2 comprises circle 1, metal chassis 3 before the metal and is fixed between the two a plurality of metal blades 2 that the outboard end of metal chassis 3 bottom surfaces is provided with the flange 31 of downward protrusion, and flange 31 can improve the intensity of metal chassis.
Owing to belonging to the exhaust outlet of centrifugal impeller before the metal between circle 1 and the metal chassis 3, so the flange 31 of metal chassis 3 bottom surfaces protrudes downwards, and purpose is exactly the air-out that does not affect exhaust outlet.
Claims (1)
1. centrifugal impeller comprises circle, metal chassis before the metal and is fixed between the two a plurality of metal blades, it is characterized in that the outboard end of metal chassis bottom surface is provided with the flange of downward protrusion.
