Abstract

The utility model relates to a vibration-screening type stock-distributing device for a sintering machine. Existing fixing type distributing reflecting plates are changed into a vibrated screen, meshes of the screen are bar-shaped meshes, and the meshes are from top to bottom positioned from small to big size. The utility model can make the size analysis more ideally during the distributing periods of sintering production. The utility model can better satisfy the requirements of manufacturing technique.

Description

Sintering machine vibratory sieve fraction distribution device

The utility model relates to the distribution device that a kind of Ferrous Metallurgy factory sintering machine is used, the particularly a kind of branch granularity distribution device that can strengthen particle segregation.

The distribution device that is called as " reflecting plate " that is widely used in sintering machine at present, in fact just a common steel plate with certain angle (being generally 45-50 °), is installed in the head of sintering machine according to technological requirement.In process of production, compound with used in sintering production, rotary action by the mud roller, scatter equably on this reflecting plate, rely on the gravity effect of sinter mixture self and the inclination angle of reflecting plate, the compound of sintering is evenly distributed on the chassis of sintering machine, and by means of the natural angle of rest (repose) of compound self, make bulky grain tumble lower floor naturally, granule then is distributed in the upper strata.The granularity that like this, has just formed compound strengthens from top to bottom gradually.The distributing mode of this granularity nature segregation, SINTERING PRODUCTION is to the requirement of compound size distribution just.In order further to improve the degree of this particle segregation, make it reach even more ideal cloth effect, also there is the multiple roll of use distribution device to replace the distributing mode of this reflecting plate at present, but involves great expense, be difficult to safeguard, and easy break-down.

The utility model is noticed present various distribution devices, or cloth segregation effect is undesirable, or price height, fault are many.In order to address these problems, a kind of distribution device that has the screening function is proposed, can make the particle segregation of sintering raw mix even more ideal, satisfy the technological requirement of SINTERING PRODUCTION better, and structure is simple relatively, is difficult for sizing, price is lower.

Task of the present utility model is finished like this: replace original " reflecting plate ", the cloth that the utility model proposes sieve that shakes is installed.Constituting this a kind of mode of shaking sieve can be to be arranged by certain rule and spacing by the metal rod to form.Specifically, screen cloth is made up of many rows rod from top to bottom; Strengthen successively from top to bottom between each row of spacing between the rod; And concerning same row, neither be parallel to each other between the rod, but the spacing that forms from top to bottom becomes big gradually; And whole compass screen surface is curved stepped, so that be complementary with herein relevant device better.So, in the process of cloth, bulky grain will be because of the up-small and down-big reason in rod gap, could be sieved down and postpone till the lower end, scatter the lower floor that is distributed in bed depth direction on the sintering pallet, granule then scatter just can preferentially sifting above the screen cloth be distributed in the bed depth direction above, and be that bulky grain reduces successively along bed depth direction size distribution from bottom to top, form the size distribution gradient of an even alternation, satisfied the technological requirement of SINTERING PRODUCTION, in addition, the arc that its overall structure forms is stepped, near cloth garden roller, dwindle the drop of sintering raw mix better, reduced the particle breakage that causes because of following drop impact; Also because the vibration effect of himself has reduced sizing, promoted the uniformity that compound distributes on the sintering pallet width simultaneously.

Below in conjunction with accompanying drawing, the utility model is described:

Fig. 1 is existing " reflecting plate " formula distribution device configuration diagram.

Fig. 2 is the sieve formula distribution device configuration diagram of shaking of the present utility model.

Fig. 3 is for removing A behind cloth garden roller (3) and the blending bunker among Fig. 2 to diagrammatic sketch.

In Fig. 1, reflecting plate (1) is the steel plate that certain inclination angle is arranged, and the compound (2) in the hopper is fallen on the reflecting plate (1) under the rotary action of cloth garden roller (3), and glides along the direction of arrow, and cloth is to sintering pallet (4).

In Fig. 2, the vibratory sieve (5) that has the arc step structure replaces the reflecting plate (1) of original (among Fig. 1), and other cloth process is constant.

In Fig. 3, each root metal rod (6) all is fixed on the metal beam (7) at a certain distance.Whole compass screen surface then is fixed on the framework (8), power drive and vibrating device (9) make whole sieve nest produce vibration, should be noted that a kind of arrangement form as metal rod on the whole compass screen surface, be divided into four rows from top to bottom, the spacing that every row's rod is fixed on the crossbeam is not the same, but strengthens successively from top to bottom between each row; And for each row's rod, its upper end is fixed on the crossbeam equably by certain distance, forms straight line, the lower end then is unfixed free end, and adjacent two staggered one on the other, promptly in row's rod one last, one down, successively alternately on two straight lines.On the rod diagrammatic sketch of this vibratory sieve (5) from Fig. 2 as can be seen.Like this, it is up-small and down-big just to have formed the rod gap, helps grading and segregation in the cloth process.

Advantage of the present utility model, the one, strengthen and standard the particle segregation in the cloth process, more Be conducive to produce; The 2nd, by the effect of vibration of self, can reduce or avoid the sizing putty to see and resemble, Form stable materials flow, and make material distribute more evenly at the sintering machine width; The 3rd, Structure is relatively simple, is convenient to maintenance and integral replacing.

Claims

1, a kind of sintering machine is characterized in that having adopted the sieve that shakes with vibratory sieve fraction distribution device, the screening cloth.

2, sintering machine according to claim 1 vibratory sieve fraction distribution device, its feature is that also the shape of whole compass screen surface is not a plane, but curved stepped arrangement.

3, according to the said screening formula of claim 1 distribution device, its feature also is the distribution mode of slot size, between the still different rows of same row, all is to strengthen gradually from top to bottom no matter.
