Stator of straight suspended type floatation machine
Technical field
The present invention relates to mineral and sort the technology and equipment field, particularly relate to a kind of stator of straight suspended type floatation machine that is used for the floatation equipment that non-ferrous metal, ferrous metal and nonmetallic mineral sort.
Background technology
Flotation device is made up of transmission device, bearing body, crossbeam, foam pushing device, hollow spindle, impeller, stator, stator support and cell body usually.Flotation device is mainly realized the mineralising of valuable mineral by impeller stirring and stator current stabilization.For large flotation machines, because the increase of volume needs stronger mixing power, can make stator bear bigger radial load simultaneously, general stator vane root adopts the opposite joint fillet welding, easily produces welding deformation, and intensity often causes leaf destruction when low.Along with the development of flotation technology equipment, floatation equipment is gradually to large scale development.Large flotation machines weight is bigger, and during consumable accessorys such as replacing impeller, stator, support, the whole main shaft of slinging is changed difficult; Power required during running also can increase; Consider that from economics point the life-span of consumable accessory also is that the longer the better in addition.
Summary of the invention
The objective of the invention is to overcome the prior art defective, a kind of stator of straight suspended type floatation machine of high-efficiency and economic is provided.
For achieving the above object, a kind of stator of straight suspended type floatation machine according to embodiment of the present invention is provided, it comprises the steel plate circle and is arranged in some blades on the described steel plate circle, described steel plate circle is along circumferentially evenly being provided with some holes, insert respectively in the described hole bottom of described some blades, is provided with bolt hole in the gap of the blade on described steel plate circle.
Preferably, described blade is a right-angled trapezium shape steel plate, and its bottom has the rectangle chimb, and is suitable with the hole on the described steel plate circle.
Preferably, the quantity of described blade is 16-32.
Preferably, the upper and lower upper padding plate and the lower bolster of being coated with respectively of described bolt hole, described upper padding plate and lower bolster all have and the corresponding bolt hole of described bolt hole.
Preferably, described upper padding plate is the rectangle steel plate, and described lower bolster is fan-shaped.
Preferably, the quantity of described bolt hole is 4 or 8.
Preferably, the junction of described blade and described steel plate circle is provided with backplate, is used to add protect being connected between described blade and the described steel plate circle.
Preferably, described backplate is the bent rectangular strip steel plate of its narrow spring.
Preferably, the two ends of described backplate are welded with closure plate, and colloid enters the space when being used to prevent line with rubber, and wherein said closure plate is the right angled triangle steel plate on arc limit for its hypotenuse.
Preferably, described stator is handled through line with rubber.
Technique scheme has following advantage: by root of blade being inserted in the steel plate circle hole welding and adding backplate, make root of blade have sufficient intensity; The hypotenuse and the impeller blade of blade cooperatively interact, and compact conformation has increased the mixing dynamics of ore pulp; Be provided with bolt hole at steel plate circle periphery, by bolt hole stator and tank bottom bracket fixed, replacing for convenience detach; The whole processing through line with rubber of stator reduced the wearing and tearing of mineral to it.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the embodiment of the invention provides a kind of stator of straight suspended type floatation machine, it comprises steel plate circle 1 and is arranged in blade 2 on the steel plate circle, described steel plate circle 1 is along circumferentially evenly being provided with some square openings, blade 2 is a right-angled trapezium shape steel plate, its bottom has the rectangle chimb suitable with described square opening, and described chimb inserts in the described square opening respectively and welding.The quantity of described blade 2 is 16-32, and the quantity of blade 2 is chosen as 24 among this embodiment.Be provided with bolt hole in the gap of the blade 2 on described steel plate circle 1, the upper and lower upper padding plate 3 and the lower bolster 4 of being coated with respectively of described bolt hole, described upper padding plate 3 and lower bolster 4 all have and the corresponding bolt hole of described bolt hole.Add man-hour, at the bolt hole on the reprocessing backing plate behind each composition backing up and down of the bolt hole on the steel plate circle 1.Preferably, described upper padding plate is the rectangle steel plate, and described lower bolster is fan-shaped.Preferably, the quantity of described bolt hole is 4 or 8.In order to make blade have sufficient intensity, present embodiment preferably is provided with backplate 5 in the junction of blade 2 and steel plate circle 1, is used to add protect being connected between described blade 2 and the described steel plate circle 1.Described backplate 5 can be the bent rectangular strip steel plate of its narrow spring.In order to reduce the wearing and tearing of mineral to stator, present embodiment carries out line with rubber to stator integral body to be handled, and preferably, is welded with closure plate 6 at the two ends of described backplate 5, colloid enters the space when being used to prevent line with rubber, and wherein said closure plate 6 is the right angled triangle steel plate on arc limit for its hypotenuse.
Stator of straight suspended type floatation machine in the embodiment of the invention, is surrounded on around the impeller on flotation device cell body support by bolting, and is highly adjustable by support, matches with impeller; The trapezoidal hypotenuse of stator vane is relative with impeller back taper hypotenuse, but blade hypsokinesis 0~miter angle, and this inclination angle is projection and blade bottom inside center and the steel plate circle circle center line connecting angle of blade centreline on the steel plate circle.Stablize flow of slurry to, weaken the rotational flow of ore pulp, the fluid dynamics that gas, solid, liquid three-phase mixture are produced in the flotation device cell body satisfies the requirement of floatation kinetics, that is: force three-phase mixture to change Radial Flow into by strong axial flow, strong axial flow is produced by the impeller rotation; The bubble that makes mineralising is along with radial flow contacts, collides with flotation trough inwall, and changes stable upwelling into, discharges cell body by downflow weir, thereby produces good sorting result.
As can be seen from the above embodiments, the embodiment of the invention makes root of blade have sufficient intensity by root of blade being inserted in the steel plate circle hole welding and adding backplate; The hypotenuse and the impeller blade of blade cooperatively interact, and compact conformation has increased the mixing dynamics of ore pulp; Be provided with bolt hole at steel plate circle periphery, by bolt hole stator and tank bottom bracket fixed, replacing for convenience detach; The whole processing through line with rubber of stator reduced the wearing and tearing of mineral to it.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
