Description
本発明は、冷却回転ドラム用集塵装置に関する。 The present invention relates to a dust collector for a cooling rotary drum.
従来、鋳造後の高温状態にある鋳造品を鋳物砂と接触させて冷却を行うと共に鋳型として使用した鋳物砂の回収をする冷却回転ドラムの先端部に設けられる集塵装置は公知にされている（例えば、特許文献１参照）。 Conventionally, a dust collector provided at the tip of a cooling rotary drum that cools a cast product in a high-temperature state after casting by contacting the foundry sand and collects the foundry sand used as a mold has been publicly known. (For example, refer to Patent Document 1).
しかし、従来は設備の停止中、冷却回転ドラム内に残った鋳物砂及び製品に大気との温度差がある限り、含まれる水分は絶えず蒸発しており、この蒸発水分が集塵機内に侵入することにより濾布表面の吸湿現象と結露の発生による目詰まりが起こるという問題があった。このため、操業の終わりは冷却回転ドラムの停止から集塵機の停止までを所定時間経過させ、該集塵機を遅延停止させている。しかし、所定時間は、冷却回転ドラム内に充満している水分を多く含む空気と大気を置換するための時間と該冷却回転ドラム停止後の発生水分量の減少具合を見計らって設定しているが、その時間は経験値によって決めており理論値ではない。また場合によっては省エネ、帰宅時間等にとらわれてその時間を短縮してしまうなど徹底が困難なため、結局、濾布の目詰まりはなかなか解決せず、該濾布の短命化をまねいている。 However, in the past, as long as there was a temperature difference between the foundry sand and the product remaining in the cooling rotating drum and the atmosphere when the equipment was shut down, the contained moisture was constantly evaporating, and this evaporated moisture would enter the dust collector. Therefore, there is a problem that the filter cloth is clogged due to moisture absorption and condensation. For this reason, at the end of the operation, a predetermined time elapses from the stop of the cooling rotary drum to the stop of the dust collector, and the dust collector is delayed and stopped. However, the predetermined time is set in consideration of the time for replacing the air containing a large amount of water filled in the cooling rotary drum with the atmosphere and the decrease in the amount of generated water after the cooling rotary drum stops. The time is determined by experience and is not a theoretical value. In some cases, it is difficult to thoroughly reduce energy consumption, return time, etc., so that the filter cloth is not easily clogged, and the filter cloth is shortened.
本発明は、上記の問題に鑑みて成されたもので、集塵機内における濾布表面の吸湿現象と結露の発生による目詰まりを防止し、該濾布の長寿命化を図ることができる冷却回転ドラム用集塵装置を提供することを目的とする。 The present invention has been made in view of the above problems, and prevents cooling caused by the moisture absorption phenomenon and condensation on the surface of the filter cloth in the dust collector, and the cooling rotation capable of extending the life of the filter cloth.

以下、本発明の実施の形態を図面に基づいて詳しく説明する。図１において、内部に鋳物砂Ｓ及び鋳造品Ｗが投入された状態で回転されることにより該鋳物砂Ｓ及び鋳造品Ｗを冷却する冷却回転ドラム１の先端部の上方には、集塵機２が配設されている。なお集塵機２内部には仕切り板２ａが取り付けられており、この仕切り板２ａにより該内部は除塵室２ｂと清浄空気室２ｃに仕切られている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, a dust collector 2 is disposed above the front end of a cooling rotary drum 1 that cools the foundry sand S and the cast product W by being rotated with the foundry sand S and the cast product W being inserted therein. It is arranged. A partition plate 2a is attached inside the dust collector 2. The partition plate 2a partitions the interior into a dust removal chamber 2b and a clean air chamber 2c.
また前記清浄空気室２ｃには送風機３が連通されており、前記仕切り板２ａには複数の濾布２ｄ、２ｄが吊設されている。また前記冷却回転ドラム１の出口１ａは吸引通路６を介して前記除塵室２ｂに連通されている。なお該吸引通路６はフード４及びダクト５により構成される。そして、該吸引通路６にはダンパ７が連通されており、本実施形態では該ダンパ７は前記吸引通路６の一部を構成する前記ダクト５の上部に取り付けられている。 A blower 3 communicates with the clean air chamber 2c, and a plurality of filter cloths 2d and 2d are suspended from the partition plate 2a. The outlet 1 a of the cooling rotary drum 1 communicates with the dust removal chamber 2 b through a suction passage 6. The suction passage 6 includes a hood 4 and a duct 5. A damper 7 is communicated with the suction passage 6. In this embodiment, the damper 7 is attached to an upper portion of the duct 5 that constitutes a part of the suction passage 6.
このように構成されたものの作動について説明する。まず、回転される冷却回転ドラム１内に、その入口１ｂから鋳物砂Ｓ及び鋳造品Ｗが投入される。そして、該鋳物砂Ｓ及び鋳造品Ｗは冷却回転ドラム１の回転に伴い、該冷却回転ドラム１の先端に向かって進んでいく。なお冷却回転ドラム１内には図示されない注水手段により注水がなされるようになっており、該注水された状態で鋳造品Ｗが転動されながら鋳物砂Ｓと繰り返し接触されることにより該鋳造品Ｗが冷却される。 The operation of the apparatus configured as described above will be described. First, the foundry sand S and the cast product W are put into the rotating cooling drum 1 from the inlet 1b. The foundry sand S and the cast product W advance toward the tip of the cooling rotary drum 1 as the cooling rotary drum 1 rotates. Note that water is poured into the cooling rotary drum 1 by water injection means (not shown), and the cast product W is repeatedly brought into contact with the foundry sand S while rolling while the water is being poured. W is cooled.
そして、冷却回転ドラム１の先端まで到達した鋳造品Ｗは出口１ａから排出され、図示されないコンベヤで次工程に送られる。また冷却回転ドラム１の先端部には図示されない多数の小孔が穿孔されており、鋳物砂Ｓは、この小孔から該先端部の下方に排出され、図示されない回収手段で回収される。 And the casting W which reached | attained the front-end | tip of the cooling rotation drum 1 is discharged | emitted from the exit 1a, and is sent to the following process with the conveyor which is not shown in figure. In addition, a large number of small holes (not shown) are drilled in the front end portion of the cooling rotary drum 1, and the foundry sand S is discharged from the small holes below the front end portion and is collected by a collecting means (not shown).
そして、該冷却回転ドラム１の回転作動中には送風機３も一緒に作動される。この送風機３の作動により、冷却回転ドラム１の入口１ｂから大気が吸い込まれ、含塵空気が出口１ａから排出される。なお本実施形態では、出口１ａから排出された含塵空気は吸引通路６、即ち、フード４及びダクト５を通って除塵室２ｂに流入されるようになっている。 During the rotation of the cooling rotary drum 1, the blower 3 is also operated. By the operation of the blower 3, the atmosphere is sucked from the inlet 1b of the cooling rotary drum 1, and the dust-containing air is discharged from the outlet 1a. In the present embodiment, the dust-containing air discharged from the outlet 1a flows into the dust removal chamber 2b through the suction passage 6, that is, the hood 4 and the duct 5.
そして、該除塵室２ｂに流入された含塵空気は複数の濾布２ｄ、２ｄで濾過され、清浄空気として清浄空気室２ｃに流入される。その後、該清浄空気室２ｃに流入された該清浄空気は送風機３によって大気に放出される。また濾布２ｄ、２ｄの外表面に付着した粉塵は図示されない払い落とし手段により払い落とされ、鋳物砂Ｓを回収する前記図示されない回収手段に回収される。なお送風機３作動中はダンパ７は閉じられている。 The dust-containing air that has flowed into the dust removal chamber 2b is filtered by the plurality of filter cloths 2d and 2d, and flows into the clean air chamber 2c as clean air. Thereafter, the clean air that has flowed into the clean air chamber 2 c is released to the atmosphere by the blower 3. The dust adhering to the outer surfaces of the filter cloths 2d, 2d is removed by a not-shown dropping means, and collected by the not-shown collecting means for collecting the foundry sand S. The damper 7 is closed while the blower 3 is operating.
そして、例えば、一日の操業の終わりには冷却回転ドラム１が停止される。その後、送風機３の作動が停止されると、該送風機３の停止に連動してダンパ７が開かれ、集塵機２内及び冷却回転ドラム１内より発生する水分を含む空気が該ダンパ７から大気に放出される。そして、例えば、次の日の操業の始めには冷却回転ドラム１及び送風機３が作動されるが、このとき、送風機３の作動に連動してダンパ７は閉じられる。 For example, the cooling rotary drum 1 is stopped at the end of the day's operation. Thereafter, when the operation of the blower 3 is stopped, the damper 7 is opened in conjunction with the stop of the blower 3, and air containing moisture generated from the dust collector 2 and the cooling rotary drum 1 is transferred from the damper 7 to the atmosphere. Released. For example, at the beginning of the operation on the next day, the cooling rotary drum 1 and the blower 3 are operated. At this time, the damper 7 is closed in conjunction with the operation of the blower 3.
本発明では、集塵機２内の水分を含む空気を放出させるダンパ７を設け、送風機３の停止に連動して該ダンパ７を開くようにしている。これにより、冷却回転ドラム１の停止中に蒸発する水分を含む空気を送風機３の停止中にダンパ７から集塵機２外へ放出することができる。このため、集塵機２内における濾布２ｄ、２ｄ表面の吸湿現象と結露の発生による目詰まりを防止し、該濾布２ｄ、２ｄの長寿命化を図ることができる。また該ダンパ７からの前記水分を含む空気の放出は送風機３の停止中に行われるため、送風機３の作動時間を減少させることができる。 In the present invention, a damper 7 that releases air containing moisture in the dust collector 2 is provided, and the damper 7 is opened in conjunction with the stop of the blower 3. Thereby, the air containing the water | moisture content evaporated while the cooling rotation drum 1 is stopped can be discharged from the damper 7 to the outside of the dust collector 2 while the blower 3 is stopped. For this reason, it is possible to prevent clogging due to the moisture absorption phenomenon on the surface of the filter cloths 2d and 2d and the occurrence of condensation in the dust collector 2, thereby extending the life of the filter cloths 2d and 2d. Further, since the air containing moisture from the damper 7 is released while the blower 3 is stopped, the operation time of the blower 3 can be reduced.
なお本発明の実施形態では、ダンパ７を吸引通路６に連通させたが、これに限定されるものではなく、該ダンパ７を集塵機２、即ち、除塵室２ｂ又は清浄空気室２ｃに連通させるようにしてもよい。ただし、ダンパ７を除塵室２ｂに連通させると、前記水分を含む空気を濾布２ｄ、２ｄを通過する前に集塵機２外へ放出することができ、水分が濾布２ｄ、２ｄに及ぼす影響をより少なくできるため好ましい。また上述の実施形態のようにダンパ７を吸引通路６に連通させると、前記水分を含む空気を除塵室２ｂ内に流入する前に集塵機２外へ放出することができ、水分が濾布２ｄ、２ｄに及ぼす影響をさらに少なくできるため、さらに好ましい。 In the embodiment of the present invention, the damper 7 is communicated with the suction passage 6. However, the present invention is not limited to this, and the damper 7 is communicated with the dust collector 2, that is, the dust removal chamber 2b or the clean air chamber 2c. It may be. However, if the damper 7 is communicated with the dust removal chamber 2b, the air containing the moisture can be discharged out of the dust collector 2 before passing through the filter cloths 2d and 2d, and the influence of moisture on the filter cloths 2d and 2d is affected. This is preferable because it can be made smaller. Further, when the damper 7 is communicated with the suction passage 6 as in the above-described embodiment, the air containing the moisture can be discharged out of the dust collector 2 before flowing into the dust removal chamber 2b, and the moisture can be filtered through the filter cloth 2d, This is more preferable because the influence on 2d can be further reduced.
