Abstract
The invention discloses a special aluminum oxide vibratory screening device to remove impurities in aluminum oxide. The special aluminum oxide vibratory screening device comprises a vibration source and a casing. A material inlet is arranged at the upper end of the casing, and the lower end of the casing is fixedly connected with a flange which is arranged at the material inlet position. The flange at the material inlet position, a screen group and a material outlet flange are integrally connected in a bolt connection mode. After a bolt is demounted, the screen group can be drawn out from between the flange at the material inlet position and the material outlet flange. The lower end of the material outlet flange is fixedly connected with a material outlet and a sundry port. The screen covers the upper end of the material outlet. An air inlet used for conveying light materials is formed on the casing. The special aluminum oxide vibratory screening device has the advantages that the mechanical vibration and wind fluidization conveying mode is adopted so sundries can be removed and the aluminum oxide conveying capacity of a vibratory screen can be improved; the screen group can be drawn out from between the two flanges so the screen group can be changed and repaired conveniently.
Description
Technical field
The present invention relates to a kind of aluminium oxide electric and magnetic oscillation screening plant, the device can remove the impurity in alumina particle,
Can be widely applied to the aluminium oxide cleaning system in aluminum electrolysis industry.
Background technology
In aluminum electrolysis industry, the primary raw material for being used is alumina particle, and the granule has that hardness is high, granularity is little, stream
The characteristic such as dynamic property is good and easily the moisture absorption is hardened, and containing impurity such as stone, broken woven bags.
Aluminium oxide containing impurity often results in relevant device failure, increase operation and maintenance cost, has a strong impact on aluminium electroloysis
Production efficiency, be lifted the efficiency, it is necessary to purify aluminium oxide, the impurity gone in alumina.
At present, the impurity that vibrosieve is removed in particulate matter is commonly used, mineral industry is applied to the vibrosieve, it is impossible to efficiently steady more
Surely alumina particle is purified, the high standard purification for also failing to reach alumina particle is required.
The content of the invention
To solve the above problems, it is necessary to the technological process of attribute and electrolytic aluminium for aluminium oxide, a kind of remove impurity is designed
Equipment, to lift the purification efficiency of alumina particle.
The present invention is designed according to alumina particle particular attribute and aluminum electrolysis technology flow process, is a kind of efficient, stable
Alumina particle knot screen.Concrete scheme is as follows：
A kind of aluminium oxide device for vibration screening, the aluminium oxide device for vibration screening is made up of pendulum and vibration source, described
Pendulum includes three parts, i.e. charging group, screening group and blanking group, and three part is by bolt-connection, the charging group bag
Include flange at charging aperture, housing and charging；The blanking group includes discharging opening flange, discharging opening, debris mouth；After removing bolt,
The screening group can be extracted out from charging between flange and discharging opening flange；The upper end of the housing is fixedly connected charging aperture, described
The lower end of housing is fixedly connected with flange at charging；The discharging opening flange lower end is connected with discharging opening and debris mouth；It is described solid
Determine connected mode and include but is not limited to welding manner；The upper end of the discharging opening covers screen cloth；Screen cloth in screening group is located at out
The top of material mouth, can both be completely covered the area above discharging opening, and debris mouth must not be covered again；The discharging opening and debris mouth
Blanking angle is more than or equal to the angle of repose for conveying material；Air inlet is also set up on the housing, the air inlet is arranged on charging
The lower end of mouth；The circular in cross-section of the housing.
The top of the housing also sets up access hole.
During conveying fresh aluminum oxide granule, the blanking angle of the discharging opening and debris mouth is 45 degree of angles.
The vibration source is arranged on one end of housing.
The vibration source is arranged on the both sides of housing.
Damping spring is set under housing.
It is an advantage of the invention that：Using mechanical vibration and the fluidised mode of movement of wind-force, debris were both can remove, can have been carried again
The ability of high vibration sieve conveying aluminium oxide；Screening group 4 can be extracted out between two flanges, be conveniently replaceable screen cloth and maintenance.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Illustrate the present invention below in conjunction with the accompanying drawings, as shown in figure 1, including vibration source 9 and housing 2, the housing 2 it is upper

The screening group lower end and the bolt connection of discharging opening flange 7, the discharging opening flange lower end is connected with discharging opening 6 and debris mouth 8；
The upper end of the discharging opening 6 covers screen cloth.Remove bolt after, the screening group 4 can from charging flange 3 and discharging opening flange 7
Between extract out；
Overhaul for convenience and check, the top of the housing 2 also sets up access hole 5；
Smooth to ensure discharging, the blanking angle a of the discharging opening 6 and debris mouth 8 is more than or equal to conveying resting in peace for material
Angle；
During conveying fresh aluminum oxide granule, the blanking angle a of the discharging opening 6 and debris mouth 8 is 45 degree of angles；
To prevent the debris of lighter weight, such as woven bag fragment to be mixed in material, on the housing 2 air inlet is also set up
10, the air inlet 10 is arranged on the lower end of charging aperture, and air outlet faces material, and the air inlet 10 is connected with airduct；
To adapt to different situations, the angle of the air inlet 10 and air quantity are adjustable；
The vibration source is arranged on one end of housing 2；
The vibration source is arranged on the both sides of housing 2；
2 times setting damping springs of housing；
In the present invention, vibration source 9 is to provide the device of certain amplitude vibration, and the vibration source 9 can adopt electromagnetic exciting source,
The exciting source of other modes, such as mechanical type vibration source can be adopted.
In the present invention, the angle regulator of air inlet 10 can adopt common method, the method such as fixed using bolt.
Screen cloth in screening group is located at the top of discharging opening 6, and the area of the top of discharging opening 6 can be both completely covered, and again must not
