Abstract

The utility model relates to a segregation distributor for an oscillating riddle, which is suitable for the screening and the particle segregation of sintering mixed material as well as the screening and the particle segregation of the bulk material of the industries of cloth, metallurgy, cement, etc. The main structure is characterized in that an inventor changes or adjusts the eccentric direction of adjacent eccentric wheels through the adjustment of key groove connection position between the eccentric wheels and eccentric wheel shafts, screen strips can swing up and down and move to and fro (adjacent screen strips have opposite swinging and moving directions) and the layer separation with intervals is realized. In addition, a steel brush (2) is arranged on a steel brush bracket (3) to remove the material which is stuck on the roots of the screen strips for small oscillation (detailed in an attached figure 1). Thereby, the utility model has the advantages of convenient use, good cloth segregation effect, no material stick, long service life, etc.

Description

A kind of swing bar grizzl(e)y segregation distribution device

The utility model is a kind of sinter mixture screening, particle segregation cloth and metallurgy, the screening of industry bulk materials such as mine, cement and plant equipment of particle segregation of being used for.

The segregation distribution method of bulk material is a lot of at present, both at home and abroad in SINTERING PRODUCTION widespread usage be the reflecting plate segregation method, the great advantage of this method is not limited by material condition, equipment is simple, but this distributing mode is little to the segregation degree of one-tenth of raw material, and effect is relatively poor.The segregation distribution method also has magnetic roller cloth segregation method, belt reflecting plate segregation method, vibration reflecting plate segregation method, cylinder reflecting plate segregation method, shaped form reflecting plate segregation method, sieve shape reflecting plate segregation method, multiple roll segregation method, air segregation method, double-layer cloth segregation method.At present especially with the development of Japanese Nippon Steel with the novel reinforced screening material distributing machine of rotary type three row's (immobilizing) gratings for its feature, its particle segregation is big, material distributes good, make the sintering index be improved significantly.But the easy sizing of this kind material distributing machine uses and finds, with regard to the material condition that China uses, its sizing phenomenon is especially serious.

It is effective that the purpose of this utility model provides a kind of particle segregation, to the wide sizing not of raw material applicability, easy operating, the sintering segregation distribution device of long service life.It is applicable to all big or small sintering machines.

For achieving the above object, the utility model can be realized by following technical measures.Adopt the critical piece of bar grizzl(e)y as stock grading, bar grizzl(e)y becomes a row to gather, distance between every grating is determined according to the granularmetric composition of raw material, the shape of grating can be column and taper, for increasing the service life, also can adopt cross section is plug type (chock plug is down), the grating that it is radially diminished to the top cross section continuously by root, and grating is by making through the stainless steel or the common straightcarbon steel of heat treatment or surface spraying.

The purpose of this utility model can also reach by following measure: every grating all can swing up and down, the front and back pull, and its amplitude of vibration, frequency adjustable, and also the direction of motion of adjacent grating is opposite.Grating can be divided into two layers or three layers up and down in motion process, by the root radial.

Description of drawings: Fig. 1. Vibration rod screen segregation step glassware front view, Fig. 1 E is that E is to view.Fig. 2. Vibration rod screen segregation step glassware vertical view.Fig. 3. the cutaway view of single grating.

Among the figure: the 17-motor 18-controller of the low case 11-rolling axle 12-set bolt 13-bearing shell 14-key 15-belt pulley 16-V-belt of 1 grating 2-steel brush 3-steel brush frame 4-running roller 5-stock guide 6-loam cake 7-grating holder 8-eccentric wheel 9-axle 10-.

Further specify below in conjunction with accompanying drawing:

Grating 1 is arranged into a row, and as shown in Figure 2, the distance between every grating is formed according to raw material granularity and set, and the grating radical is decided by the sintering machine size.Every grating 1 is linked by bolt 12 and grating holder 7 by running roller 4 supportings; By the slip transmission between bearing shell 13 realization grating holders 7 and the eccentric wheel 8; Eccentric wheel 8 is connected by key 14 with axle 9, drives 2 keyways on the eccentric wheel 8, and the angle between the keyway is 120 °; Axle is uniform on 9 drives two keyways, and the connection position by adjusting key and the direction of eccentric wheel 8 can realize that the eccentric direction between adjacent eccentric wheel becomes 120 ° and 180 °.Axle 9 is driven by belt pulley 15, V-belt 16 and motor 17, behind electric motor starting, drives grating 1 and does oscillating motion like this, because the difference of eccentric direction, the grating of bar grizzl(e)y becomes two rows or three rows up and down by the radiation of running roller 4 places, shown in Fig. 1 E.

The amplitude of fluctuation of grating 1 realizes by the position of regulating running roller 4; The frequency of grating swing is regulated by controller 18.

By steel brush 2, steel brush support 3 is cleared up the grating root and may be sticked at material on the grating 1 because swing is little.

Realize that by the running part of under casing 10 and 6 pairs of distributing devices of loam cake sealing is with lubricated.

Stock guide 5 makes material enter distributing device, and it is stable that material is fallen, and transversely material is evenly distributed.

This swing bar grizzl(e)y segregation distribution device is installed in below the barrel feeder, and starting transmission mechanism can come into operation.Sinter mixture or material fall into stock guide by the barrel feeder feed, then drop to bar grizzl(e)y.Fine particle then falls from the grating root in the compound, and particle more slightly then moves downward along grating, falls to certain position, and the largest particles is then discharged from the grating top.Thereby can realize the classification segregation of granularity.As sizing or the change of blanking amount appear, then can expect clearly, and reach best segregation effect by adjustment control.

Through on-the-spot probationary certificate, this cloth glassware has that cloth branch is good, and particle segregation is big, Especially the effect that cannot not have stickingly material.
