Under given rotational speed, radially the linear velocity of each point is incremented by by inner ring to outer ring the furnace bottom of shape, is adopted in the case
With existing charging gear, cloth is unanimously carried out to furnace bottom with speed in charging gear width direction, will cause material in annulus
Material accumulation on the furnace bottom of shape on the inner ring direction obtain it is more thicker, the material accumulation on outer ring direction obtain it is less compared with
Thin, thickness of the material on furnace bottom is inconsistent, and such case will cause that annular furnace production efficiency is low, the relatively thin part mistake of cloth
Reaction, the thicker partial reduction of cloth is insufficient, reduces the ratio of reduced iron, has seriously affected being normally carried out for technical process,
Product, which is unable to reach, requires quality.
Summary of the invention
There are label in this, it, can be by material equably cloth the present invention provides a kind of annular material receiving device and its distributing method
It is placed in the circular rotary furnace bottom of annular furnace, so that the consistency of thickness everywhere of the material on furnace bottom, and then ensure technical process just
It often carries out, it is ensured that the production efficiency and product quality of annular furnace.
The present invention is achieved through the following technical solutions:
A kind of annular material receiving device provided by the invention, including vibration cabinet, the vibration excitor on the vibration cabinet, sets
In the vibration bottom of box and there is the cloth bottom plate of curved inclined surface structure and be set on the cloth bottom plate and in the vibration cabinet
Width direction is in multiple separated material baffles of parallel interval distribution, the curved inclined surface structure of the cloth bottom plate are as follows: in the vibration cabinet
Incline along the opposite direction of furnace bottom rotation and the vibrating bin body length direction along furnace bottom outer ring to furnace bottom inner ring direction in width direction
Obliquely and curvature of curved surface is incremented by.
Further, construct the curved inclined surface structure of the cloth bottom plate boundary be respectively as follows: furnace bottom inner ring cloth boundary and
Furnace bottom outer ring cloth boundary with vibration cabinet proj ected bottom intersect a diagonal baseline, be located at vibrate cabinet width direction
What upper and top line far from furnace bottom central diameter and higher than baseline and and the two corresponding end ipsilateral in top line and baseline were connected to form
Preceding sideline and rear sideline.
Further, the top line, baseline, preceding sideline and rear sideline are not in same level and respectively end to end.
Further, the quantity of the separated material baffle is determined according to the curvature range of cloth bottom plate and furnace bottom rotation speed.
Further, the charging front end of the cloth bottom plate is equipped with sieve pore.
The present invention has the advantages that the curved inclined surface that the present invention is special using vibration box baseplate, in given vibration frequency
Under the driving of amplitude, in vibration cabinet width direction, material will fall into annular furnace furnace from cloth material mouth with different delivery speed
Bottom, delivery speed it is fast fall into furnace bottom outer ring, delivery speed it is slow fall into furnace bottom inner ring, different delivery speed corresponds to different
Cloth doses realizes the uniform distribution to annular furnace furnace bottom so that the thickness of feed layer of furnace bottom everywhere is consistent, it is ensured that technique mistake
Journey is normally carried out, improves production efficiency and product quality.
Other advantages, target and feature of the invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.Target of the invention and other advantages can be realized by following specification and
It obtains.
Detailed description of the invention
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
The detailed description of one step, in which:
Fig. 1 is the structural schematic diagram of the annular material receiving device of the present invention；
Fig. 2 is the M-M cross-sectional view of Fig. 1；
Description of symbols: top line 1；Sieve pore 2；Separated material baffle 3；Sideline 4 afterwards；Preceding sideline 5；Baseline 6；Vibration excitor 7；Vibrate cabinet
8；Cloth bottom plate 9.
In addition, A, B, C, D are the intersection point of top line, rear sideline, preceding sideline, baseline；X is material receiving device length direction, and Y is

Specific embodiment
Illustrate embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this specification
Other advantages and efficacy of the present invention can be easily understood for disclosed content.The present invention can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing from
Various modifications or alterations are carried out under spirit of the invention.It should be noted that diagram provided in following embodiment is only to show
Meaning mode illustrates basic conception of the invention, and in the absence of conflict, the feature in following embodiment and embodiment can phase
Mutually combination.
As shown in Figure 1, 2, the present invention provide annular material receiving device by vibration cabinet 8, vibration excitor 7, there is curved inclined surface knot
The cloth bottom plate 9 and separated material baffle 3 of structure form, top line 1 of the cloth bottom plate 9 far from annular furnace furnace bottom central diameter, baseplate width direction
On rear sideline 4 and preceding sideline 5, cloth material mouth baseline 6 not in same level, and head and the tail are mutually crossed to form A, B, C, D tetra-
A intersection point, by solid geometry basic knowledge it is found that with top line 1, rear sideline 4, preceding sideline 5, the song that baseline 6 is boundary line building
Face, curvature are gradually incremented by tri- directions X, Y, Z, inclination of gradually sinking in the x, y direction, the inclination of above-mentioned continuously smooth
Curved surface constitutes cloth bottom plate 9.
When the material receiving device works, the amplitude and vibration frequency vibration that the operating of vibration excitor 7 will make entire material receiving device to give,
Material enters after cloth bottom plate 9, screens out the powder part in material in the sieve pore 2 of screen area, qualified granule materials
It will assemble to Y-direction during being vibrated, i.e., in material receiving device width direction, material thickness is by B point to A point direction
It gradually increases；Driving granule materials are walked material by material receiving device vibration in the X direction, i.e., on material receiving device length direction from B point to C
Point, A point to D point walk material；Due to constitute cloth bottom plate 9 curved inclined surface also in the Y direction gradually sink inclination and curvature gradually
It is smooth to increase, each not phase of delivery speed in 6 deflector chutes such as material a, b, c, d, e, f made of being isolated as separated material baffle 3
It speeds together and one by one, it may be assumed that delivery speed a < b < c < d < e < f, cloth doses a < b < c < d < e < f fall into circular furnace
The particulate matter doses at bottom will be successively decreased from outer ring to inner ring, be arranged in the granule materials on entire furnace bottom by each point consistency of thickness, in fact
The purpose of existing uniform distribution, it is ensured that technical process is normally carried out, improves production efficiency and product quality, and the purpose of the present invention obtains
To realization.
It is merely a preferred embodiment of the present invention, is not intended to restrict the invention, it is clear that those skilled in the art described in upper
