Abstract

The utility model relates to the field of ventilation equipment. A centrifugal impeller comprises a front metal ring, a metal chassis and a plurality of metal blades which are fixed between the front metal ring and the metal chassis. The front metal ring is composed of an inner ring and an outer ring, and the inner ring and the outer ring are connected in an integrated manner, and a turnup protruding upward is arranged on the end portion outside the outer ring top surface. The centrifugal impeller has the advantages of being novel in design and high in strength of the front metal ring.

Description

Centrifugal impeller
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, the circle external lateral portion is burnishing surface before existing its metal of metal centrifugal impeller, and the deficiency of its existence is that circle intensity is low before the metal.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to solve existing centrifugal impeller, and a kind of novel structure is provided, the high centrifugal impeller of circle intensity before the metal.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
Centrifugal impeller comprises circle, metal chassis before the metal and is fixed between the two a plurality of metal blades that circle is made of the inner ring that is connected as a single entity and outer ring before the metal, and flange protruding upward is set on the outboard end of outer ring end face.
As preferably, the reinforcement flange of downward protrusion is set on the outboard end of described metal chassis bottom surface, strengthen the intensity that flange can the reinforcement metal chassis.
Adopted the centrifugal impeller of above-mentioned technological scheme, flange protruding upward has been set on the outboard end of outer ring end face.The advantage of this centrifugal impeller is novel structure, and the intensity of circle is high before the metal.
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, comprise circle 1, metal chassis 3 before the metal and be fixed between the two a plurality of metal blades 2, circle 1 is made of the inner ring 11 that is connected as a single entity and outer ring 12 before the metal, on the outboard end of outer ring 12 end faces flange protruding upward 13 is set.The reinforcement flange 31 of downward protrusion is set on the outboard end of metal chassis 3 bottom surfaces, strengthens the intensity that flange 31 can the reinforcement metal chassis.
Because belong to the exhaust outlet of centrifugal impeller before the metal between circle 1 and the metal chassis 3, so the flange 13 of outer ring 12 end faces is protruding upward, the reinforcement flange 31 of metal chassis 3 bottom surfaces protrudes downwards, purpose is exactly the air-out that does not affect exhaust outlet.

Claims (2)

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 metal before circle consisted of by the inner ring that is connected as a single entity and outer ring, flange protruding upward is set on the outboard end of outer ring end face.
2. centrifugal impeller according to claim 1 is characterized in that arranging on the outboard end of metal chassis bottom surface the reinforcement flange of downward protrusion.
