Background technology:
Blower fan is the machinery for carrying gas, from the viewpoint of energy, it is a kind of machinery that the mechanical energy of prime mover is gas energy, gas is accelerated by the impeller utilizing high speed rotating, then slow down, change the flow direction, making kinetic energy be converted into potential energy (pressure), impeller is the parts uniquely done work gas in the process.Therefore impeller is a vitals on blower fan, and performance is had a significant impact by its geometry, size, lobe numbers and the accuracy of manufacture.
Large-scale impeller majority uses integral casting forming technology, for small-sized impeller, owing to the dimensional accuracy of casting cannot meet the thickness requirement of impeller blade, thick and heavy cast blade means higher energy consumption, more conventional processing method is powder metallurgy casting or Digit Control Machine Tool overall processing, but the efficiency of both approaches is the lowest, relatively costly.
Utility model content:
The purpose of this utility model be aiming at deficiency that prior art exists and provide a kind of be easy to manufacture and assemble, draught fan impeller that production cost is low.
To achieve these goals, the technical solution adopted in the utility model is: draught fan impeller, include circular rear trochal disc, it is positioned at wheel disc before the annular in rear trochal disc front, multichip connection blade between rear trochal disc and front wheel disc, rear trochal disc, the material of front wheel disc and blade is aluminium alloy, more blades is distributed uniformly and circumferentially, rear trochal disc integral middle forms the cylindric shaft sleeve part protruded out forward, shaft sleeve part offers axis hole at axle center, vane nose face and rear end face have protruded out Plug Division respectively, the position that rear trochal disc is corresponding with each Plug Division with on front wheel disc offers the jack coordinated with Plug Division respectively, each Plug Division of each blade is plugged in corresponding jack respectively, and Plug Division is connected by riveting method and jack are fixing.
Between inner peripheral and the rear trochal disc of described front wheel disc, between the outer peripheral edge of front wheel disc and rear trochal disc, it is respectively equipped with filter screen.
Described vane nose face and rear end face have protruded out multiple Plug Division respectively.
The rear end of described shaft sleeve part extends back the rear end face of rear trochal disc.
Keyway is offered on the axis hole sidewall of described shaft sleeve part.
The middle part of described rear trochal disc rear end face is provided with dust-proof support roller.
nullThis utility model has the beneficial effects that: the draught fan impeller that this utility model provides，Include circular rear trochal disc、It is positioned at wheel disc before the annular in rear trochal disc front、Multichip connection blade between rear trochal disc and front wheel disc，Rear trochal disc、The material of front wheel disc and blade is aluminium alloy，More blades is distributed uniformly and circumferentially，Rear trochal disc integral middle forms the cylindric shaft sleeve part protruded out forward，Shaft sleeve part offers axis hole at axle center，Vane nose face and rear end face have protruded out Plug Division respectively，The position that rear trochal disc is corresponding with each Plug Division with on front wheel disc offers the jack coordinated with Plug Division respectively，Each Plug Division of each blade is plugged in corresponding jack respectively，And Plug Division is connected by riveting method and jack are fixing，Traditional impeller is separated into front wheel disc by this utility model、Rear trochal disc and three independent parts of blade，Various piece is separately machined，Easily fabricated，Machining accuracy is high，Reduce the weight of impeller，Reduce energy consumption，And blade and front wheel disc、Carry out assembling and fixing between rear trochal disc by the way of grafting and riveting combine，It is easily assembled to，Efficiency is high，Connected mode is more sturdy and durable，Production cost is low.
