Abstract
Description
本発明は、アルミニウム溶解炉用集塵フードに関する。
The present invention relates to a dust collection hood for an aluminum melting furnace.
従来、アルミニウム溶解炉用集塵フードの一つとして、アルミニウム溶解炉のほぼ周囲を包囲しかつアルミニウム溶解炉に対して原料を搬入出させる原料搬入出手段が通過可能な開口を有するフード本体と、このフード本体の上端に装着されてフード本体内の粉塵を集めかつ集塵機に連通接続された天井部と、から成るものがある。 Conventionally, as one of the dust collection hoods for an aluminum melting furnace, a hood main body that has an opening that surrounds substantially the periphery of the aluminum melting furnace and through which raw material loading / unloading means for loading / unloading the raw material to / from the aluminum melting furnace can pass. There is a ceiling unit that is attached to the upper end of the hood body, collects dust in the hood body, and is connected to the dust collector.
しかし、このように構成された従来のアルミニウム溶解炉用集塵フードでは、原料投入時に舞い上がった粉塵が開口から比較的多量流出する。 However, in the conventional dust collecting hood for an aluminum melting furnace configured as described above, a relatively large amount of dust that has risen when the raw material is charged flows out from the opening.
解決しようとする問題点は、集塵フードにおいて原料投入時に舞い上がった粉塵が開口から比較的多量流出する点である。
The problem to be solved is that a large amount of dust that has risen when the raw material is charged in the dust collecting hood flows out from the opening.
上記の課題を解消するために本発明におけるアルミニウム溶解炉用集塵フードは、アルミニウム溶解炉に配設した集塵フードにあって、前記アルミニウム溶解炉のほぼ周囲を包囲しかつアルミニウム溶解炉に対して原料を搬入出させる原料搬入出手段が通過可能な開口を有するフード本体と、このフード本体の上端に装着されてフード本体内の粉塵を集めかつ集塵機に連通接続された天井部と、この天井部における前記開口との対向位置に上下回動可能に装着されて開口の上部部分を開閉可能な扉と、を備えたことを特徴とする。
In order to solve the above problems, a dust collection hood for an aluminum melting furnace according to the present invention is a dust collection hood disposed in an aluminum melting furnace, and surrounds the aluminum melting furnace and surrounds the aluminum melting furnace. A hood main body having an opening through which a raw material carrying-in / out means through which the raw material is carried in / out can be passed, a ceiling portion that is attached to the upper end of the hood main body and collects dust in the hood main body and is connected to a dust collector, and the ceiling And a door that can be pivoted up and down at a position facing the opening of the opening and can open and close the upper portion of the opening.
このように構成したものは、通常は扉を下方へ回動させて開口の上部部分を閉じ、原料搬入出手段が原料をアルミニウム溶解炉へ投入する時だけ扉を上方へ回動させて開口の上部部分を開ける。 In such a configuration, the door is usually rotated downward to close the upper portion of the opening, and the door is rotated upward only when the raw material loading / unloading means puts the raw material into the aluminum melting furnace. Open the upper part.
上記の説明から明らかなように本発明は、アルミニウム溶解炉に配設した集塵フードにあって、前記アルミニウム溶解炉のほぼ周囲を包囲しかつアルミニウム溶解炉に対して原料を搬入出させる原料搬入出手段が通過可能な開口を有するフード本体と、このフード本体の上端に装着されてフード本体内の粉塵を集めかつ集塵機に連通接続された天井部と、この天井部における前記開口との対向位置に上下回動可能に装着されて開口の上部部分を開閉可能な扉と、を備えたから、原料搬入出手段が原料をアルミニウム溶解炉へ投入する時だけ扉を上方へ回動させて開口の上部部分を開けることができるため、原料投入時に舞い上がった粉塵が開口から流出する量を可及的に少なくすることができるなどの優れた実用的効果を奏する。
As is apparent from the above description, the present invention relates to a dust collection hood disposed in an aluminum melting furnace, which encloses the aluminum melting furnace and surrounds the aluminum melting furnace and carries the raw material into and out of the aluminum melting furnace. A hood main body having an opening through which the ejecting means can pass, a ceiling portion that is attached to the upper end of the hood main body, collects dust in the hood main body, and is connected to the dust collector, and a facing position of the opening in the ceiling portion And a door that can be pivoted up and down to open and close the upper part of the opening, so that when the raw material loading / unloading means puts the raw material into the aluminum melting furnace, the door is rotated upward to open the upper part of the opening. Since the portion can be opened, an excellent practical effect is achieved such that the amount of dust that has risen when the raw material is charged flows out from the opening can be reduced as much as possible.
本発明を適用した集塵フードについて図１に基づき詳細に説明する。図示するように、本集塵フードは、アルミニウム溶解炉１のほぼ周囲を包囲しかつアルミニウム溶解炉１に対して原料を搬入出させる原料搬入出手段としてのフォークリフト２が通過可能な開口３を有するフード本体４と、このフード本体４の上端に装着されてフード本体４内の粉塵を集めかつ集塵機（図示せず）に連通接続された天井部５と、この天井部５における前記開口３との対向位置に上下回動可能に装着されて開口３の上部部分を開閉可能な扉６と、で構成してある。そして、扉６は、前記天井部５に枢支した図示しないシリンダの伸縮作動によって上下回動するようになっている。
A dust collection hood to which the present invention is applied will be described in detail with reference to FIG. As shown in the figure, the dust collection hood has an opening 3 that surrounds the aluminum melting furnace 1 and that allows a forklift 2 as a material loading / unloading means for loading / unloading the material to / from the aluminum melting furnace 1 to pass therethrough. A hood body 4, a ceiling portion 5 that is attached to the upper end of the hood body 4, collects dust in the hood body 4, and is connected to a dust collector (not shown), and the opening 3 in the ceiling portion 5. The door 6 is mounted at an opposing position so as to be pivotable up and down, and can open and close the upper portion of the opening 3. The door 6 is configured to rotate up and down by an expansion / contraction operation of a cylinder (not shown) pivotally supported on the ceiling portion 5.
このように構成したものは、通常はシリンダの収縮作動により扉６を上方へ回動させて開口３の上部部分を開き、フォークリフト２が原料をアルミニウム溶解炉１へ投入する時だけ扉６を上方へ回動させて開口３の上部部分を開ける。 In such a configuration, the door 6 is usually rotated upward by the contraction operation of the cylinder to open the upper portion of the opening 3, and the door 6 is moved upward only when the forklift 2 puts the raw material into the aluminum melting furnace 1. To open the upper part of the opening 3.
