Abstract
The invention discloses a fan impeller for improving strength of blades, which comprises a hub, an annular rear disk connected to the periphery of the bottom part of the hub, a plurality of blades with the bottom edges fixed on the upper surface of the rear disk, and an annular front disk connected with the top edges of the blades, wherein the side edges of the blades, which are far away from the hub, are respectively provided with a flange. The fan impeller has the beneficial effects that: the outer edges of the blades of the fan impeller and the connection parts of the blades and the hub are strengthened, so that the normal use of the blades at high temperature and high rotating speed is ensured.
Description
Technical field
The present invention relates to the industrial ventilation technical field, relate in particular to a kind of industrial furnace propellant circuit draught fan impeller that is used for.
Background technique
Temperature is higher in the industrial furnace that heat treatment is used, to be used for propellant circuit blower fan particularly the impeller in the blower fan higher requirement is arranged.The common revolution of impeller is about 1480rpm, and industrial furnace for example in the perhydro bell-type furnace, is atmosphere of hydrogen; In order to make the gas circulation in the stove faster; Reach the abundant exchange of heat, need to improve impeller rotation to 2100～2200rpm, existing like this impeller intensity just is difficult to satisfy usage requirement.
The structure of impeller comprises wheel hub in the existing technology, the hub disk, the end that are in the peripheral annular of wheel hub be along blade that is fixed on the back panel surface and the shroud that connects the annular on edge, blade top.Wheel hub is cylinder or the cone that has axial hole; Through hole is used to penetrate live axle; If closing on a side of wheel hub, extends the ordinary circumstance lower blade until linking to each other with the wheel hub outer wall; Then be referred to as linear leaf, be not connected, then be referred to as short blade with the wheel hub outer wall otherwise blade closes on a side of wheel hub.
Existing impeller is when high rotating speed uses under high temperature condition, to the intensity of blade self and and other parts between join strength have relatively high expectations, otherwise use can cause distortion under high temperature condition, influences the normal use of whole draught fan impeller.
Summary of the invention
The invention provides a kind of draught fan impeller that blade has been carried out the reinforcement processing, can avoid the use of the deformation of blade in the process.
A kind of draught fan impeller that improves blade strength; The hub disk, the end that comprise wheel hub, be connected the annular of wheel hub bottom periphery,, blade had flanging away from the side edge of wheel hub along the shroud that is fixed on some blades of hub disk upper surface and connects the annular on all edges, blade top.
As preferably, described blade extends internally and is connected with the wheel hub outer wall, is fitted with reinforced sheet at blade with the position that the wheel hub bottom is connected.
As preferably, the side of described reinforced sheet is connected with the wheel hub outer wall, and the base of reinforced sheet is connected with the upper surface of hub disk.
As preferably, described reinforced sheet be shaped as polygonal or fan-shaped.
The invention has the beneficial effects as follows to the outer of the blade of draught fan impeller and with the connection part of wheel hub and strengthen, guaranteed the normal use of blade under high temperature, high rotating speed.
Description of drawings
Fig. 1 is the generalized section of draught fan impeller of the present invention;
Fig. 2 is along A-A line sectional view among Fig. 1.
Embodiment
Referring to Fig. 1,2; Draught fan impeller of the present invention comprises that wheel hub 3, wheel hub 3 have axial hole and be used to penetrate live axle, and wheel hub 3 bottom periphery are provided with the hub disk 1 of annular, 4 ends of blade all are fixed on the shroud 2 of annular along the edge, top that is fixed on hub disk 1 upper surface, blade 4 bottom surface.
The description in relevant orientation among the present invention, as upper and lower, top, the end be among the figure, do not represent absolute orientation.
The side of reinforced sheet 6 is connected with the mode of wheel hub 3 outer walls through welding, and the base of reinforced sheet 6 is connected through the mode of welding with the upper surface of hub disk 1.
In the present embodiment reinforced sheet 6 be shaped as quadrilateral, the present invention strengthens to the outer of the blade 4 of draught fan impeller and with the connection part of wheel hub 3, has guaranteed the normal use of blade 4 under high temperature, high rotating speed.
