Description
Technical field
The present invention relates to a kind of flotation device sorted for mineral more particularly to a kind of impellers of flotation device.
Background technique
Flotation device is a kind of equipment sorted under the conditions of gas-liquid-solid three-phase for mineral, it mainly by driving device, stir
Mix shafting, impeller, stator and groove body composition.Flotation device is mainly realized the suspension of ore pulp in flotation cell and is had by impeller stirring
With the mineralising of the collision of mineral and bubble.Flotation machine impeller carries energy input, bubble formation and dispersion and ore pulp suspension etc.
Function is flotation device most critical component.With the continuous development of floatation equipment enlargement, the bigger torque of impeller needs carrying,
The design of its structure design and performance will have that separation performance is good, intensity is high, long service life, the characteristics such as low energy consumption.
In the prior art, Fig. 1 a to Fig. 1 e is the flotation machine impeller announced or authorized and the air method of salary distribution:
Fig. 1 a is a kind of flotation machine impeller and air distributor that patent CN1012945B is announced, and impeller is double back taper hypsokinesis
Impeller, air distributor are absolute construction, pass through being connected and fixed between impeller and axis.
Fig. 1 b is a kind of air distributor that patent WO2011069314A1 is announced, which is absolute construction,
Whole cylindrical, side wall or bottom are provided with several ventholes of different shapes.
Fig. 1 c is a kind of flotation machine impeller that patent CN101708488B is announced, and being mainly characterized by blade is in double back taper knots
Structure, blade tilts backwards certain angle, and its impeller cover is bent upwards camber.
Fig. 1 d is a kind of flotation machine impeller that patent US6805243B1 is announced, and feature is mainly that blade edge is arc-shaped,
Each blade is radially distributed, and angle, without inclination, all blades insides are connected, and in root (top) position of blade, there are go out
The flat mouth of gas.
Fig. 1 e is a kind of flotation machine impeller that patent WO2008062097A1 is announced, it is characterized in that blade edge is arc-shaped,
Assembling mode is manufactured using piecemeal, gas outlet is to be spaced apart between blade.
The shortcomings that above-mentioned prior art:
Fig. 1 a, Fig. 1 b, the impeller of Fig. 1 c and air orchestration are that applying unit and its parent company are all, are widely used in me
In the models flotation device such as state KYF, CLF, both impeller and air distributor are relatively independent mechanisms.And with equipment enlarging
Afterwards, impeller size also increases with it, and the stirring torque of transmitting also significantly increases, and the blade of Fig. 1 a and Fig. 1 c impeller is all
Mutually independent, only vaned root is connected with impeller end plate, and blade is in " cantilever " state, by root intersity limitation
System, the huge torque that unbearable impeller is transmitted, thus it is not suitable for super large type flotation machine application.
Fig. 1 d and Fig. 1 e are external flotation device impeller, and impeller blade is radially distributed, its energy consumption under same working condition
It is higher than the backward tilt blade impeller of Fig. 1 a, Fig. 1 b, Fig. 1 c.The each blade of Fig. 1 d is in overall construction, and impeller blade is in impeller
Heart district domain, which is converged, becomes solid construction, from impeller end plate until the least significant end of blade, 8 blades are that prismatic blade is uniformly distributed, the structure
The impeller cavity volume of same diameter becomes smaller down, and internal circulating load becomes smaller.Fig. 1 e is in order to easy to make, and blade is manufactured using piecemeal, then
It is assembled into a whole impeller, blade bottom is reinforced with reinforcing ring again, and plays certain guide functions, and manufacture craft also compares
Complexity, 8 blades are that prismatic blade is uniformly distributed, and energy consumption is larger.
Summary of the invention
The object of the present invention is to provide a kind of impellers of flotation device.
The purpose of the present invention is what is be achieved through the following technical solutions:
The impeller of flotation device of the invention, including cover board, blade, outlet baffle, the outlet baffle are set to impeller

Specific embodiment
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art well known to professional and technical personnel in the field.
The impeller of flotation device of the invention, preferable specific embodiment is:
Including cover board, blade, outlet baffle, the outlet baffle is set to the top position of impeller center, the leaf
The interior lateral margin of piece is fixedly connected with the side wall of the outlet baffle, the cover board be set to the blade top and with the leaf
The upper limb of piece is fixedly connected, and the outer surface of entire impeller is coated with wearing layer.
The top of the outlet baffle is hollow cylindrical tube, and lower part is hollow or solid cone structure or semicircle
The inner cavity of shape structure, the outlet baffle is connected with the air duct of hollow shaft, and the side wall of the hollow cylindrical tube is set
There is venthole.
The framework material of the lower area of the lateral border of the blade is recessed inwardly, and depressed area is filled out by the wearing layer
It is flat.
The lateral border of the blade is in double back taper structures, middle and upper part back taper knot along the surface of revolution of the axis of outlet baffle
The cone angle of structure is less than the cone angle of the back taper structure of lower part, and the interior lateral margin of the blade is vertical edge structure.
The blade quantity is 6-10, and the circumferential direction along the outlet baffle is uniformly distributed, from axial vertical view, each blade edge
Radially retreat 15~75 degree of angles.
The venthole is circle or rectangular, and the venthole is distributed in the gap between two blades.
The outlet baffle total height is no more than the 2/3 of the impeller height.
The cover board is rounded, and the central region of upper surface has boss, uniformly distributed and flotation device hollow shaft on the boss
Connected bolt hole and keyway, boss center are equipped with round through-hole, the air duct of the hollow shaft and the outlet baffle
Inner cavity pass through the round through-hole connection.
The blade meets and is respectively arranged with bearing rib between pulp noodle and back pulp noodle and the cover board, wherein the branch of back pulp noodle
Support gusset size is greater than the bearing rib size for meeting pulp noodle.
Flotation machine impeller of the invention had not only met Aerated stirring demand, but also had enough intensity, supported the defeated of large torque
Out, while running low in energy consumption, separation performance is good, adapts to super large type flotation machine application requirement.
Specific embodiment:
Impeller is made of cover board 1, blade 2, outlet baffle 3 and wearing layer 4.Wherein the cover board 1 of impeller is a circular ring shape
Plate, and it is provided with around inner ring the bolt hole for flanged joint.Blade 2 is double back taper blades, is easily ground in hypocone
Damage region is recessed inwardly, convenient for adhering to more wear-resistant coatings.The pulp noodle of meeting of blade 2 are provided with front support gusset 5, carry on the back pulp noodle
It is provided with rear support gusset 6, the size of rear support gusset 6 will be noticeably greater than front support gusset 5.Blade 2 and 1 Joint of cover board exist
