Abstract
The utility model discloses dustproof fan impeller which comprises a wheel disk and blades. The blades are evenly distributed on the wheel disk in a bent mode. Each blade comprises a bent face inner side and a bent face outer side, one end of each blade close to the wheel disk upwards extends from thick to thin, and an arc notch is positioned at the roof of each blade. The dustproof fan impeller is novel and simple in structure, firm in structure, capable of effectively reducing dust accumulation degree, convenient to process, low in cost and suitable for being popularized in a large range.
Description
Technical field
The utility model relates to a kind of draught fan impeller, especially relates to a kind of draught fan impeller that can reduce dust.
Background technique
In the industrial processes such as building materials, electric power and metallurgy, be used for the centrifugal blower that the dispatch humidity of flue gas is large, dust granules is less and viscosity is larger, service time, the faults such as blower fan undercapacity and decrease in efficiency, body vibration, parts damage will not appear in length, so that blower fan can't be worked, and what impact was produced normally carries out.Check to analyze and find, the reason that causes these faults is on the non-working surface of blade because the high-speed impact of cement grit, formed hard sediments piece on its surface, after sediments adheres to a certain degree, the formation nonuniformity comes off, cause impeller balance to destroy and vibrate, finally affect whole manufacturing efficiency.And the blower fan of some dust protections appears on the market, mostly complex structure involves great expense, and is not suitable for promoting the use of on a large scale.
The model utility content
The utility model provides a kind of simple in structure in order to overcome the deficiencies in the prior art, has the draught fan impeller that dust protection overstocks.
To achieve these goals, the utility model is by the following technical solutions: a kind of dust protection draught fan impeller, comprise wheel disc and blade, and blade is sweeping to be distributed on the wheel disc, it comprises the inboard and flexure plane outside of flexure plane, and described blade is extended upward to thin by thick from the end near wheel disc; The root of blade is provided with arc notch.
As preferably, described blade is 1.2mm near the thickness of an end of wheel disc, is 0.5mm away from the thickness of an end of wheel disc.
As preferably, be coated with polytetrafluoroethylene floor outside the flexure plane of described blade.
The utlity model has following advantage: the utility model novel structure, simple, firm in structure, can effectively reduce the overstocked degree of dust, and also easy to process, cheap, suitable for large-scale promotion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
A kind of dust protection draught fan impeller comprises wheel disc 1 and blade 4, blade 4 sweeping being distributed on the wheel disc 1, and it comprises flexure plane inboard 41 and the flexure plane outside 42, blade 4 is extended upward to thin by thick from the end near wheel disc 1; The root of blade 4 is provided with arc notch 2.Described blade 4 is 1.2mm near the thickness of an end of wheel discs 1, is 0.5mm away from the thickness of an end of wheel disc 1.The flexure plane outside 42 of blade 4 is coated with polytetrafluoroethylene floor.
Blade of the present utility model has increased wind speed by thick to thin setting, and the root of blade has an arc notch, has changed near the flow field structure the bending blade outer side surface leading edge, prevents that effectively dust granules from adhering on the blade; And by be coated with one deck polytetrafluoroethylene floor at arc plate, more reduced the stickiness of dust; And the utility model novel structure, simple, easy to process, cheap, suitable for large-scale promotion.
