Description

[Detailed Description of the Invention] The present invention relates to a belt conveyor that sequentially loads and conveys a plurality of raw materials.

FIG. 1 shows a well-known belt conveyor for conveying sintering raw materials.The belt conveyor 1 is connected to a bunker 2, that is, a plurality of raw materials 3a to 3 which are separated from several bunkers 2a to 2e.
3e are loaded one after another and transported to a subsequent conveyor 4 or subsequent equipment (not shown) such as a mixer.

By the way, in such a belt conveyor 1, when a finely powdered raw material such as quicklime is placed on the top layer of the conveyor, the finely powdered raw material may be blown away by the wind or at the conveyor transition area, worsening the environment. This was causing a decrease in yield.

Further, the plurality of raw materials loaded on the belt conveyor 1 must be uniformly mixed at the final stage, that is, at the stage where they are supplied to the sintering machine.

For this reason, a mixer is appropriately provided in the sintering raw material conveyance process.

The present invention prevents the scattering of fine powder raw materials as described above,
It is an object of the present invention to provide a belt conveyor that also makes it possible to mix a plurality of raw materials.

Hereinafter, the present invention will be described in detail based on figures showing embodiments.

FIGS. 2 and 3 are a plan view and a sectional view showing an embodiment based on the present invention.

In FIGS. 2 and 3, 5 is a raw material surface mixing device (
The mixing device 5 is composed of a plow-like plate 6 and a pedestal 7 on which the plow-like plate 6 is mounted and held.

The frame 7 is mounted above the belt conveyor 1.
is placed across the.

The spade-like plate 6 is attached to the pedestal 7 in a detachable or movable manner.

As shown in FIG.
In this embodiment, it is arranged at an appropriate position behind the raw material cutting section of the bunker 2e.

In the belt conveyor 1 of the present invention, the surface layer of the raw materials stacked on the conveyor is scraped together by the plow-like plate 6 of the mixing device 5, and mixed by the scraping operation.

For example, when fine powder quicklime 3f is loaded on the top layer as shown in Figure 3, the conveyor narrows in the direction of movement (arrow a) as shown in Figures 2 and 3. A plow-like plate 6 attached to the pedestal 7 at an angle of inclination collects fine and coarse raw materials such as ore powder and coke powder in the lower layer so as to cover the quicklime, effectively preventing the quicklime from scattering. to prevent.

At the same time, the plurality of raw materials stacked on the conveyor were mixed by the scraping operation, and it became possible to perform rough mixing on the belt conveyor 1 before being supplied to the mixer in the latter stage.

In the experience of the present inventors, even if the mixing ratio is small, the coarse mixing functions as a pretreatment for the mixer and is extremely effective in increasing the mixing efficiency in the mixer. Many excellent effects were confirmed, such as effectively preventing the phenomenon of raw materials adhering to the inner wall surface of the mixer.

FIG. 4 is a plan view showing another embodiment based on the present invention.

The mixing device 50 of this embodiment is constructed by mounting a plurality of spade-like plates 60 on a pedestal 70 at appropriate intervals in the width direction of the belt conveyor 1.

The spade-like plates 60 have an optimum waveform inclination angle to enhance the scraping operation of the raw materials, that is, to enhance the mixing effect, and are arranged in multiple stages in the conveyor traveling direction a.

As described above, the present invention uses a belt conveyor 1 carrying a plurality of raw materials one after another, and mixes the fine powder raw materials conveyed by scraping the surface layer or plowing the surface layer using the mixing devices 5 and 50. This prevents scattering and enables mixing of raw material layers.

Therefore, the plow-like plates 6, 60 are arranged according to the thickness of the raw material layer on the conveyor.
In order to efficiently perform the desired raking operation, it is preferable that the height of the surface of the bell can be adjusted as appropriate.

For example, as shown in FIG. 3, an elongated mounting hole 8 is drilled in the pedestal 7, and a well-known bolt 9 is used to fix the mounting hole 8 to the mounting hole 8, or a plow-shaped plate 6 is fixed as shown in FIG. The rear upper part of the plate is rotatably supported by a pin 10, and an adjustment rod 11 is attached to the tip thereof, and the spade-like plate 6 is swung by adjusting the adjustment rod 11. Although the means for making the adjustment is not shown, What is necessary is just to adopt the means etc. which can be mounted via a lifting device such as a cylinder device and remotely controlled, etc., as appropriate.

In the present invention, the raw material surface layer refers to the portion of the raw material layer that is scraped together by the spade-like plates 6, 60 whose heights are adjusted.

In addition, in order to avoid damaging the bell Ha and improve wear resistance, the plow-like plates 6 and 60 may be constructed by applying a rubber lining to an ordinary steel plate, or by attaching a rubber plate to the lower part of an ordinary steel plate. is effective, and the plow-like plate 6,6
0 is preferably detachably attached to the mounts 7 and 70 in order to facilitate replacement.

By the way, if the layer of raw material on the conveyor is thin and it is necessary to load fine powder raw material on the top layer, as shown in Figure 5, the raw material layer before loading the fine powder raw material is For example, although not shown in the figure, the groove 12 may be
If the fine powder raw material 3f is placed in the groove 12, the above-mentioned scraping operation can be carried out efficiently and safely without damaging the bell Ha using the mixing device 5.50 of the present invention. It is.

According to the experience of the present inventors, quicklime is added to the top layer of the raw material at 14 T/H using a belt conveyor with a conveyance capacity of CJoo T/H.
According to the results of investigating the amount of dust sucked in by the dust collector at the conveyor transfer section in an example in which the conveyor was loaded at a ratio of
By implementing this invention, what used to be ITon/day will become ITon/day.
It was confirmed that the quantitative yield improvement was remarkable.

As described above, although the present invention has a simple configuration, its practical effects are very large.
