Description

【0001】
【発明の属する技術分野】
本発明は、槽から塊状または粉状の原料を下工程設備に切り出し、移送する振動フィーダに関するものである。
【0002】
【従来の技術】
ホッパー等から塊または粉状の原料を下工程の搬送設備または、加工装置に移送する手段として振動フィーダが使用されている。この振動フィーダにおいては、図9および10に示すように、トラフ3aの内面に取付けられたライナー3bの角部3cに原料粉Ms が付着、成長し、原料の流れを阻害するようになる。この原料粉Ms の付着量が多くなると、振動フィーダの移送量が大幅に低下したり、終いには振動フィーダが過負荷が原因で停止するようになる。
【0003】
このような事態を回避するため、従来、次のように対処していた。
(1)図8に示す振動フィーダの吊りボルト7を調整して振動フィーダ3の傾斜を増加して、原料粉Ms の付着速度を減少させる。
(2)振動フィーダの加振器のボリュームを増して、原料粉Ms の付着速度を減少させる。
(3)一定運転時間たったら、操業または運転を中止して、人手によりトラフの付着物の除去を行う。
【0004】
【発明が解決しようとする課題】
しかしながら、前記の(1)および(2)の対処法は、付着物の除去間隔を長くすることはできるが、定期的に人手による除去作業を実施しなければならない。この除去は、狭隘で、粉塵等が飛散する劣悪な環境下での作業となることから、この作業を無くすることが望まれていた。
【0005】
本発明は、トラフ内面の原料付着を防止できる振動フィーダを提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明は上記目的を、原料が移動するトラフと該トラフを振動させる加振器からなり、塊または粉状の原料を水平または斜め下向きに搬送する振動フィーダにおいて、気体をトラフ角部に沿って下流方向に気体の流束が扁平状に吹き出すように、トラフの上流端部の原料が落下する場所を外した両角部の底面近傍に気体の吹き出しノズルを設けた振動フィーダによって達成する。
【0007】
「作用」
トラフの上流端部の両角部の底面近傍に気体の吹き出しノズルを設けてあるから、付着物の多い角部に沿って気体の流れが発生し、原料の付着を防止する。また、気流は原料を乾燥させるから一層原料がトラフ内面に付着しにくくなる。
【0008】
吹き出しノズルの取付け場所がトラフの上流端部の両角部であるから、吹き出しノズルの先端が、原料の直撃を受けない。
【0009】
【発明の実施の形態】
槽またはホッパーから塊または粉状の原料を、下流の設備(反応容器、搬送設備等)に切出すために振動フィーダが多く使用されている。この振動フィーダの使用例を図5により説明する。ベルトコンベヤで搬送されてきた原料は、トリッパー1により槽2に供給される。下流の反応容器6への原料投入タイミングに合わせて 槽2に貯蔵された原料は、振動フィーダ3を運転して切り出される。振動フィーダ3から排出された原料は、中間ホッパー4およびシュート5を介して反応容器6に投入される。一定量の原料が投入された後、前記振動フィーダ3は停止する。このように、振動フィーダ3は、反応容器の操業サイクルに従って一定間隔で運転−停止が繰り返される。
【0010】
また、振動フィーダは、長時間連続運転される搬送設備(ベルトコンベヤ、パン型コンベヤ等)と槽の間に設けられ、槽内の原料を前記搬送設備に切出す設備として使用されている。
【0011】
次に、本発明の実施の形態を図面により以下に説明する。
図1は、本発明の振動フィーダの部分破断側面図、図2は、図1のA−A矢視図である。2は鉱石、副原料等の塊または粉状の原料を収容する槽またはホッパー、3は振動フィーダ、3aはそのトラフ、3bはトラフ3aを摩耗から保護するために、その内面に取付けられたライナーで耐摩耗性の金属板でできている。3dは振動フィーダの加振器であり、その振幅、振動数を変えることができる。3eは振動フィーダの排出口である。
【0012】
上記のように構成された振動フィーダ3に、本発明では、トラフ3aの上流端部の両角部3c,3cの底面近傍に2本の気体吹き出しノズル10、10を、図3および4に示すように、その先端をライナーから突出させて設けている。図4に示した破線で囲んである領域DAは、上部の槽2から原料が落下する場所である。上述した如く、気体吹き出しノズル10、10は、この領域DAを外して取付けてあるので、これらが落下する原料の直撃を受けることはない。
【0013】
気体吹き出しノズル10、10には、図1に示すように、圧縮空気の配管12から弁13およびフレキシブル(可撓性)管11を介して圧縮空気が供給される。フレキシブル管11は、振動フィーダ3の振動を吸収し、圧縮空気の配管12および弁13に伝えない。ノズル10に供給される圧縮空気の量は、弁13により調節される。この弁は、振動フィーダ3の運転開始の信号を受けて自動的に開となり、運転停止で閉となる。
【0014】
なお、トラフ3aの長さが長くて片側1本のノズル10では、原料の付着を充分防止できない場合は、ノズル数を適宜増加すればよい。図6および7に、ノズル10の先端形状の一例を示した。このようにすれば、少ない圧縮空気量でも、ノズル出口における流速を増加させ、気体の動エネルギーを増加させることができる。また、気体の流束を偏平にし広い面積の原料の付着防止をカバーすることができる。
【0015】
なお、圧縮空気では、その含有する酸素によって反応容器で発生する可燃性ガスが異常燃焼して不具合な場合は、圧縮空気に変えて窒素ガスを使用すればよい。
【0016】
【発明の効果】
本発明は、原料の付着する振動フィーダの角部に沿って高速の気体流を下流側に向かって形成させるように構成したから、原料の付着を防止することができ、従来の劣悪な環境下での人手による付着物除去作業を皆無にすることができる。また、付着物除去作業のための操業停止がなくなるから、生産性が向上するという副次的効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a vibration feeder that cuts and transfers a block or powdery raw material from a tank to a lower process facility.
[0002]
[Prior art]
A vibration feeder is used as a means for transferring a lump or powdery raw material from a hopper or the like to a lower-stage transport facility or processing apparatus. In this vibrating feeder, as shown in FIGS. 9 and 10, the raw material powder M s to the corners 3c of the liner 3b attached to the inner surface of the trough 3a is attached, grown, so to inhibit the flow of material. When the amount of deposition of the raw material powder M s increases, or the amount of the transfer is greatly reduced vibration feeders, so to stop due to vibration feeder overloaded to put away.
[0003]
In order to avoid such a situation, conventionally, the following measures have been taken.
(1) Adjust the hanging bolt 7 of the vibrating feeder 8 increases the inclination of the vibration feeder 3, reduce adhesion speed of the raw material powder M s.
(2) increasing the volume of the vibrator of the vibrating feeder, reduce adhesion speed of the raw material powder M s.
(3) After a certain operation time, the operation or operation is stopped and the trough deposits are removed manually.
[0004]
[Problems to be solved by the invention]
However, although the countermeasures (1) and (2) described above can lengthen the removal interval of the deposits, it is necessary to periodically perform manual removal operations. Since this removal is a narrow work and is performed in a poor environment where dust or the like scatters, it has been desired to eliminate this work.
[0005]
An object of this invention is to provide the vibration feeder which can prevent the raw material adhesion of a trough inner surface.
[0006]
[Means for Solving the Problems]
The present invention aims to achieve the above object, in a vibratory feeder comprising a trough for moving a raw material and a vibrator for vibrating the trough, and conveying a lump or powdery raw material horizontally or obliquely downward. This is achieved by a vibration feeder provided with gas blowing nozzles in the vicinity of the bottom surfaces of both corners excluding the place where the raw material at the upstream end of the trough falls so that the gas flux blows out in the downstream direction.
[0007]
"Action"
Since the gas blowing nozzles are provided in the vicinity of the bottom surfaces of both corners at the upstream end of the trough, a gas flow is generated along the corners where there is a large amount of deposits, thereby preventing the attachment of raw materials. Moreover, since the airflow dries the raw material, the raw material is less likely to adhere to the inner surface of the trough.
[0008]
Since the installation location of the blowing nozzle is at both corners of the upstream end of the trough, the tip of the blowing nozzle is not directly hit by the raw material.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Vibrating feeders are often used to cut lump or powdery raw materials from tanks or hoppers into downstream equipment (reaction vessels, transport equipment, etc.). An example of use of this vibration feeder will be described with reference to FIG. The raw material conveyed by the belt conveyor is supplied to the tank 2 by the tripper 1. The raw material stored in the tank 2 in accordance with the raw material charging timing to the downstream reaction vessel 6 is cut out by operating the vibration feeder 3. The raw material discharged from the vibration feeder 3 is charged into the reaction vessel 6 through the intermediate hopper 4 and the chute 5. After a certain amount of raw material has been charged, the vibration feeder 3 stops. Thus, the vibration feeder 3 is repeatedly operated and stopped at regular intervals according to the operation cycle of the reaction vessel.
[0010]
Further, the vibration feeder is provided between a transport facility (belt conveyor, bread type conveyor, etc.) that is continuously operated for a long time and the tank, and is used as a facility for cutting out the raw material in the tank to the transport facility.
[0011]
Next, embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a partially broken side view of the vibration feeder of the present invention, and FIG. 2 is a view taken along the line AA of FIG. 2 is a tank or hopper for storing a lump or powdery raw material such as ore and auxiliary materials, 3 is a vibration feeder, 3a is its trough, 3b is a liner attached to its inner surface to protect the trough 3a from abrasion It is made of wear-resistant metal plate. 3d is a vibrator of the vibration feeder, and its amplitude and frequency can be changed. 3e is a discharge port of the vibration feeder.
[0012]
In the vibration feeder 3 configured as described above, in the present invention, two gas blowing nozzles 10 and 10 are provided in the vicinity of the bottom surfaces of both corners 3c and 3c at the upstream end of the trough 3a as shown in FIGS. Further, the tip is provided so as to protrude from the liner. A region DA surrounded by a broken line shown in FIG. 4 is a place where the raw material falls from the upper tank 2. As described above, since the gas blowing nozzles 10 and 10 are attached with the area DA removed, they are not directly hit by the raw material from which they fall.
[0013]
As shown in FIG. 1, compressed air is supplied to the gas blowing nozzles 10 and 10 from a compressed air pipe 12 through a valve 13 and a flexible pipe 11. The flexible pipe 11 absorbs the vibration of the vibration feeder 3 and does not transmit it to the compressed air pipe 12 and the valve 13. The amount of compressed air supplied to the nozzle 10 is adjusted by the valve 13. This valve is automatically opened in response to the operation start signal of the vibration feeder 3, and is closed when the operation is stopped.
[0014]
If the length of the trough 3a is long and the single nozzle 10 on one side cannot sufficiently prevent the adhesion of raw materials, the number of nozzles may be increased as appropriate. An example of the tip shape of the nozzle 10 is shown in FIGS. In this way, even with a small amount of compressed air, the flow velocity at the nozzle outlet can be increased and the kinetic energy of the gas can be increased. Further, it is possible to cover the prevention of adhesion of a raw material having a large area by flattening the gas flux.
[0015]
In the case of compressed air, if the combustible gas generated in the reaction vessel is abnormally burned due to oxygen contained therein, nitrogen gas may be used instead of compressed air.
[0016]
【The invention's effect】
Since the present invention is configured to form a high-speed gas flow toward the downstream side along the corner of the vibration feeder to which the raw material adheres, it is possible to prevent the raw material from adhering to the conventional poor environment. It is possible to eliminate the work of removing deposits by hand. Moreover, since there is no operation stop for the deposit removal work, a secondary effect of improving productivity can be obtained.
