Abstract
A novel spreading plate device comprises a spreading plate, a feeding pipe, a rotor blade and counter protection plates. The counter protection plates are arranged around the spreading plate device, the spreading plate is fixed to a rotary shaft, the outer circumference of the spreading plate is provided with a check ring, the rotary shaft is sleeved with a rotary shaft protective sleeve, and the feeding pipe is located in the center of the spreading plate and is close to the rotary shaft. The spreading plate is fixed to the rotary shaft, the check ring is arranged on the circumference of the spreading plate, and materials to be separated are fed into a spreading plate bottom plate from the feeding pipe close to the rotary shaft. A material feeding point is close to the rotary shaft, so that enough time and space are available for materials to be distributed on the whole circumference of the spreading plate during outward moving, it is guaranteed that the materials are evenly distributed on the whole circumference by means of the check ring, ideal work conditions of a powder concentrator are achieved, and separation efficiency of the powder concentrator is improved.
Description
technical field:
The utility model relates to a kind of bulk material sorting unit using in cement and metallurgical mine industry material grinding process of processing, and particularly relates to a kind of novel spreading disk device.
background technology:
The screening installation using in cement and metallurgical mine industry material grinding process, ordinary circumstance is by the planar annular disk (spreading disk) of a rotation of material feeding, rotation along with disk, material spreads out along radial direction under inertia force (being commonly called as centrifugal force) effect, thereafter, after the collision of the counterattack backplate through arranging with circumferencial direction, under Action of Gravity Field, enter minute constituency and carry out sorting.Because planar annular disk (spreading disk) width is less, after material feeding, along radial direction, spread out rapidly, cause on whole spreading disk circumferencial direction and occur the free area that part does not have material to distribute, causing the short circuit of sorting wind, and then cause the powder concentrator efficiency of separation to decline.
summary of the invention:
The purpose of this utility model is for the defect of existing powder concentrator and deficiency, provide a kind of and can guarantee to treat that sorting material can evenly feed powder concentrator spreading disk, and guarantee the uniform feeding device that the whole circumference of spreading disk has material to spread out, and then reach the ideal conditions of powder concentrator work, improve the novel spreading disk device of the powder concentrator efficiency of separation.
The technical scheme that realizes above-mentioned purpose employing is:
A kind of novel spreading disk device, comprise spreading disk, feeding pipe, rotor blade and counterattack backplate, counterattack backplate is arranged on the surrounding of spreading disk, spreading disk is fixed on rotating shaft, the excircle of spreading disk is provided with ring washer, on rotating shaft, cover has rotating shaft sheath, and described feeding pipe is positioned at the zone line of spreading disk, near rotating shaft.
As preferred version
Described spreading disk device is comprised of spreading disk base plate and back-up ring, and spreading disk base plate is arranged on rotating shaft, and back-up ring is arranged on the periphery of spreading disk base plate.
Rotating shaft sheath and spreading disk base plate are connected to one.
Described rotor blade and spreading disk fit together.
Described ring washer is the entity structure of sealing or the partially enclosed formula structure that has part hole.
The height of described ring washer mates with the characteristic of the diameter of spreading disk, rotating speed and handled material.
Adopt technique scheme, compared with prior art, bulk cargo dish of the present utility model is fixed on rotating shaft, and the circumference of spreading disk is provided with ring washer, treats that sorting material is via the feeding pipe feeding spreading disk base plate near rotating shaft.Because material feeding point is near rotating shaft, when outwards moving, there are time enough and space to be covered with the whole circumference of spreading disk, the setting of ring washer guarantees that material is uniformly distributed on whole circumference, and then reaches the ideal conditions of powder concentrator work, improves the powder concentrator efficiency of separation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2, Fig. 3 are Application Examples of the present utility model.
Mark in figure: back-up ring 1, rotating shaft sheath 2, feeding pipe 3, rotor blade 7, spreading disk base plate 5, counterattack backplate 6, rotating shaft 4.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described
The utility model discloses a kind of novel spreading disk device, this spreading disk device is by back-up ring 1, rotating shaft sheath 2, feeding pipe 3, rotor blade 7, spreading disk base plate 5, counterattack backplate 6, rotating shaft 4 compositions such as grade, counterattack backplate 6 is arranged on the surrounding of spreading disk, and spreading disk is disc-shaped structure, back-up ring 1 and spreading disk base plate 5, consists of, spreading disk base plate 5 is arranged on rotating shaft 4, and on rotating shaft 4, cover has rotating shaft sheath 2.The circumference of spreading disk base plate 5 is provided with back-up ring 1.Ring washer 1 is the entity structure of sealing or the partially enclosed formula structure that has part hole.The height H of ring washer 1 depends on the characteristic of radius R, rotation speed n and the handled material of spreading disk, can be by calculating:
H=f·R
n2≥
Wherein: g-acceleration of gravity;
The tangent of an angle that stops of f-material;
The radius of R-spreading disk base plate;
The height of H-back-up ring.
Spreading disk is fixed on rotating shaft, and back-up ring 1, rotating shaft sheath 2 adopt appropriate ways to connect as one with spreading disk base plate 5.
Feeding pipe 3 is positioned at the zone line of spreading disk, near rotating shaft 4.Treat that sorting material is via the feeding pipe feeding spreading disk base plate 5 near rotating shaft.
Rotor blade and spreading disk fit together, and are up-down structure.
The course of work of the present utility model:
During powder concentrator operation, treat that sorting material is via the feeding pipe 3 feeding spreading disk base plates 5 near rotating shaft, the spreading disk of rotation makes material when moving in a circle, under effect of inertia, along radial direction, outwards move, because material feeding point is near rotating shaft 7, when outwards moving, there are time enough and space to be covered with whole circumference, when back-up ring 1 structure is closed body, when initially material movement is to back-up ring 1 place, because of motion, be obstructed and gather, after after a while, the material upper surface of piling up on spreading disk can form the reverse taper of a larger cone angle, material speed when outwards moving is slack-off, the radial motion of follow-up material is actual is to move upward along slope, whole run duration is elongated, further guaranteed material being uniformly distributed on whole circumference (seeing accompanying drawing 1), when back-up ring 1 structure is the partially enclosed structure (seeing accompanying drawing 2) that has part hole, initial material movement is behind back-up ring place, partial material can flow out from the hole of back-up ring 1, remainder material can gather and form the material surface that upper surface is inverted cone, extend the time of radial motion, keep material being uniformly distributed along circumference.
