Abstract
The utility model discloses a classifying wheel with helical blades, which comprises an upper flange plate and a lower flange plate. A plurality of blades are connected between the upper flange plate and the lower flange plate and arranged helically twistedly. The classifying wheel with the helical blades has the advantages that since the shape and the assembling manner of the blades of the classifying wheel are improved, a classifying flow field generated by the aid of the helical blades is matched with a dispersion flow field in terms of direction, integral classifying effect and efficiency are improved and performances of a classifier are improved.
Description
Technical field
The utility model relates to a kind of grading wheel of grader, and specifically a kind of helical blade grading wheel belongs to the grader field.
Background technology
Grader is made into closed cycle journey branch journey shunting ore deposit sand with ball mill in the ore dressing plant; Or be used in and come classification ore in sand form and thin mud in the gravity mill; And in the metal beneficiation flowsheet ore pulp is carried out grading, and operations such as desliming, dehydration in the washup operation.That these facility have is simple in structure, reliable operation, characteristics such as easy to operate.
Traditional classifying turbine comprises that vertical the wheel with horizontal take turns; Blade mainly adopts the structure of welding vanelets on straight-plate-type blade or the prismatic blade; The fit that blade and rim are perpendicular can produce a radial grading flow field parallel with direction of rotation when grading wheel rotates, but disperses the flow field to be actually the spiral flow field that the direction rotation of existing footpath has axial rotation again; Thereby not matching on this dispersion flow field and the scalable stream field direction influenced the classification efficiency of grader and effectiveness of classification.
The utility model content
In order to address the above problem, the utility model has designed a kind of helical blade grading wheel, and this grading wheel makes the classification flow field of formation mate on direction with disperseing the flow field through adopting helical blade, and whole grading effect and efficient are improved.
The technical scheme of the utility model is:
A kind of helical blade grading wheel comprises upper flange plate and lower flange, is connected with some blades between described upper flange plate and the lower flange, and described blade is aligned twisted in the shape of a spiral.
Further, described blade be evenly distributed on upper and lower ring flange around.
The scalable stream field direction depends on blade wheel structure and turns to; Employing is with the mode of screw blade and rim angle mount; Form helical blade grading wheel structure, the classification flow field of formation is mated on direction with disperseing the flow field, whole grading effect and efficient are improved.
The advantage of the utility model is: through the improvement of grader blade shape and fit, adopt helical blade that the classification flow field of formation is mated on direction with disperseing the flow field, whole grading effect and efficient are improved, improved the grader performance.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the cutaway view of A-A direction among Fig. 1;
Among the figure: 1-upper flange plate, 2-blade, 3-lower flange.
The specific embodiment
Below the preferred embodiment of the utility model is described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model.
As illustrated in fig. 1 and 2; A kind of helical blade grading wheel comprises upper flange plate 1 and lower flange 3, is connected with some blades 2 between described upper flange plate 1 and the lower flange 3; Described blade 2 is aligned twisted in the shape of a spiral, described blade 2 be evenly distributed on ring flange around.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
