微粉分離装置に関する。Detailed Description of the Invention [Objective of the Invention] <Industrial Application Field> The present invention provides a method for agglomerating fine powder using a fine powder agglomeration machine and transporting agglomerates formed to a predetermined size or larger into a belt conveying device. The present invention relates to a fine powder separation device for a fine powder agglomeration machine for separating mixed fine powder during conveyance in a fine powder agglomeration machine.

を低減し得る。<Conventional technology> For example, when manufacturing coke for metallurgy, it is better to dry coking coal to a certain extent before feeding it into a coke oven, which can reduce manufacturing costs by improving heating fuel consumption, coke quality, productivity, etc. .
ところで、乾燥に伴い原料炭中に混在する微粉炭が搬送

ことにより、発塵防止と合わせて加熱用燃料原単位、コ
ークスの品質及び生産性の向上も図れる。By the way, pulverized coal mixed in coking coal as it dries causes dust generation during the transportation process and when it is put into a coke oven, so measures to prevent this are necessary. For this reason, by taking out only the dryer's powder from the coking coal and feeding it into the coke oven together with the coarse coal that has been agglomerated by the fine powder agglomeration machine and from which the fine powder has been removed, it is possible to prevent dust generation and to use it for heating. It is also possible to improve fuel consumption, coke quality, and productivity.
しかし、上記微粉塊成機にて形成した塊状体には一部の
未塊成微粉が付着もしくは混在しているため、塊状体と
微粉とを分離することが望ましい。However, since some unagglomerated fine powder is attached to or mixed with the agglomerated body formed by the above-mentioned fine powder agglomeration machine, it is desirable to separate the agglomerated body and the fine powder.

という問題が生じる。However, when the above-mentioned sieve device is applied to separate the agglomerates formed by a fine powder agglomeration machine from fine powder, the agglomerates falling from the sieve toward the outlet below the sieve are transferred to a conveyor device for example to a coke oven. If the agglomerated material falls onto the belt, there is a risk that the agglomerated material will be re-pulverized, resulting in a problem of reduced yield.

For example, 0. Coarse coal of 5 mm or more is sent to a coke oven (not shown). For example, 0.0% generated in the dryer 1. Pulverized coal of 5 wua or less is collected by a dust collector 2, sent out from the dust collector 2, and thrown into a hopper 3. A fine powder agglomeration device 4 is provided below the hopper 3, and between the hopper 3 and the fine powder agglomeration device 4, as shown in FIG.
A cutting device 5 consisting of, for example, a pair of screw feeders is provided for feeding the fine powder stored in the hopper 3 into the fine powder agglomeration device 4 .

っている。The fine powder agglomeration device 4 is constructed by disposing a pair of agglomeration rolls 6 in parallel with each other so that both outer peripheral surfaces thereof can roll against each other. By appropriately rotating both agglomeration rolls 6 by a drive device (not shown), the fine powder sent from the cutting device 5 is pressed between them, and the agglomerated body of the fine powder is discharged downward. It is now possible to do so.

に戻されるようになっている。Near the bottom of both agglomeration rolls 6, there is provided a conveying device 7 having a mesh belt 7a provided with a plurality of apertures of a predetermined size. The lumps that have naturally fallen onto the upper conveyance surface of 7a are conveyed toward a coke oven (not shown) on the right side in FIGS. 1 and 2. As shown in FIG. 1, a fine powder conveying device 8 consisting of a similar belt conveyor is provided below the belt conveying device 7.

This blowing nozzle 9 is arranged so as to blow out air from the downstream side to the upstream side in the conveying direction of the belt conveying device toward the falling part of the agglomerate,
It is connected to an air source (not shown) provided on the right side of the main body of the fine powder agglomeration device 4 in the figure.

れている。As shown in FIG. 3 showing a plan view, the blowing nozzles 9 include an intermediate nozzle 9a corresponding to most of the intermediate portion of the agglomerate roll 6 in the width direction, and an intermediate nozzle 9a corresponding to most of the intermediate portion in the width direction of the agglomerate roll 6. It consists of both side end nozzles 9b arranged in parallel on both sides of an intermediate nozzle 9a to correspond to both side ends. Since the agglomeration rate of the agglomerates formed between the pair of agglomeration rolls 6 varies in the width direction of the rolls, the air volume supplied to the middle nozzle 9a and the air volume supplied to the both end nozzles 9b vary. What is the air volume?
Each air volume can be suitably adjusted by a throttle valve installed upstream of each connecting pipe connected to each nozzle 9a, 9b.

距離が短く、落下にょる再粉化をも防止し得る。In the fine powder agglomeration device 4 configured in this manner, the agglomerates formed between the two agglomeration rolls 6 and the mixed fine powder are
As the agglomeration roll 6 rotates, the fine powder naturally falls onto the mesh belt 7a, but the air blown out from the blow-off nozzle 9 blows the fine powder upstream in the conveying direction, and the agglomerates and the fine powder can be suitably separated. Therefore, the lumps can be easily sorted by the mesh belt 7a. in this way,
Fine powder and particles smaller than the mesh of the reticulated belt 7a pass through the conveyor 7 and fall, so the reticulated belt 7a can select only agglomerates larger than a predetermined size, and the size of the agglomerates to be conveyed to the coke oven can be reduced. can improve the quality of Therefore,
It is possible to prevent fine powder from being mixed in the agglomerates transported to the coke oven as much as possible, and since the belt conveying device 7 is provided near the bottom of the agglomeration roll 6, the falling distance of the agglomerates is short and there is no possibility of falling. It can also prevent re-powdering.

場合、微粉搬送装置８は設置しなくても良い。As described above, the fine powder blown by the blow-off nozzle 9 passes through the openings of the mesh belt 7a and falls, but as described above, the fine powder is collected by the belt of the fine powder conveying device 8 and returned to the hopper 3. , the yield can be improved by reusing the collected fine powder. Further, dust particles finer than fine powder are blown away by the blow-off nozzle 9, but are collected by a dust collector (not shown) through an exhaust port 10 provided above the upstream side of the fine powder agglomeration device 4 in the conveyance direction. It is now possible to do so. In addition to the above method, the reticulated belt 7a of the conveying device 7 can be removed by suitably separating the agglomerates and fine powder by the blow-off nozzle 9, and by sucking almost all the fine powder by the dust collector through the exhaust port 10. It is also possible to use a normal belt conveyor system. In this case, the fine powder conveying device 8 does not need to be installed.
