Low efficiency is mixed, power consumption is big, and handling capacity is poor, and casting cost is high, and the liquid flowing in stirred tank is in three-dimensional highly unstable rapids
Stream, pulsation and stochastic turbulence bring very big difficulty to conveying.
Summary of the invention:
In view of the deficiencies of the prior art, the present invention provides a kind of solid-liquid two-phase flow stirring-type impeller, make solid-liquid two-phase flow
Handling capacity is more preferable, high-efficient, runs more stable.
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of solid-liquid two-phase flow stirring-type leaf
Wheel, including back shroud, which is characterized in that wheel hub is fixedly connected in the middle part of the back shroud, the upside of the back shroud is fixed
Equipped with several plain vanes, the bottom side of back shroud is fixedly connected with several back blades.
Preferably, the plain vane is provided with five groups and symmetrical and equally distributed in back shroud with hub centre
Top.
Preferably, the back blade is symmetrical with hub centre and is evenly distributed on the bottom of back shroud.
Preferably, spiral-flow type blade is fixedly connected at the top of the plain vane.
The working principle of the invention: identical and equally distributed plain vane there are five being set on back shroud, in blade
In design, hydraulic performance is comprehensively considered, by blade to the acting of transmission medium, increase efficiency of transmission.The wheel hub, Ke Yiyou
Effect and transmission axis connection, transmit torque, are comprehensively considered by economic benefit and load-carrying properties, mechanical work and torque is effectively ensured
Transmitting guarantee effective transmission of medium so that it is guaranteed that the power that driving machine is transferred to medium is more effectively transferred to pumped (conveying) medium.
The spiral-flow type blade is the most crucial part of the impeller, is effectively worked by it, is improving passage capacity, raising efficiency, increase
Having in terms of the reliability service of pump significantly improves.The back blade can reduce vacuum side of blade pressure, and it is close to increase pump housing rear end
Seal reliability
The beneficial effects of the present invention are: front end spiral-flow type blade, can be used to drain with transfer of highly viscous, containing solid particle
And substance is easily blocked, it is allowed to successfully flow out, there is a twisted blade in open and close type impeller, by suction inlet edge on cone hub body
Axially-extending, back end cylindrical shape blade, the radius of blade are gradually increased, and form spiral flow channel, and Impeller Design is identical and uniform
The first centrifugal impeller of cylinder of distribution, by can transport than other forms in centrifugal impeller Front-end Design spiral-flow type blade
Non-clogging impeller performance more preferably concentration, lossless performance is good, small, high-efficient to the destructiveness of conveying material, runs more stable.And
It consumes energy low, electricity consumption is low.Achieve the purpose that economize on electricity environmental protection.
Detailed description of the invention:
Fig. 1 is the schematic perspective view of bottom side of the invention；
Fig. 2 is the schematic perspective view of top side of the invention；
Fig. 3 is plan view of the invention；
In figure: 1, back shroud 2, plain vane 3, wheel hub 4, spiral-flow type blade 5, back blade.
Specific embodiment:
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
As shown in Figures 1 and 2, a kind of solid-liquid two-phase flow novel cyclone type impeller.Blocking-free performance can be more preferable when in use, adds
The propulsion of upper inlet spiral-flow type blade so that this impeller passage capacity when conveying solid-liquid two-phase flow is more preferable, and is conveying
When the solid-liquid two-phase flow of bulky grain, high viscosity and fibrous matter, the concentration of conveying than other forms non-clogging impeller performance more
It is excellent.Lossless performance is good, and two-phase solid-liquid fluid is gradually pushed ahead in this pump, and flow direction is flowed without suddenly change
It is more stable, it is smaller than other forms non-clogging impeller to the destructiveness of conveying material.The characteristics of high-efficient and this impeller, eddy flow
Formula impeller is compared with common impeller, and because of the presence of front end spiral-flow type blade, flow velocity is uniform, more high-efficient than common impurities pump.It inhales
