This is a device that removes dust adhering to a duct of a dust collection facility in a foundry, and is a strain sensor that detects the weight of a predetermined location of the main flow duct, and a main sensor that is mounted at a predetermined location of the main flow duct. Dust removing means for removing dust adhering to a predetermined portion of the duct, and the strain sensor detects the adhesion of dust to the predetermined portion of the main flow duct by a change in the weight of the predetermined portion of the main flow duct. In this case, the dust removing means is operated, and each nozzle is mounted as the dust removing means, and this nozzle is connected to a hot air generator (not shown) via an opening / closing valve (not shown). . Then, when any of the strain sensors detects adhesion of dust due to a change in the weight of a predetermined portion of the main duct, the on-off valve (not shown) is opened, and hot air is injected from one of the nozzles. This reduces the adhesion of dust to the main duct and removes dust adhering to the inner surface of the main duct.

以下、本発明を図示例に基づいて説明すると、次の通りである。
本発明は、例えば、建築廃材用選別分離システムや集塵システムやその他のダクトを使用した適宜システムで利用可能となる吸引ダクトに於ける粉塵除去装置である。
この粉塵除去装置は、粉塵（例えば、砂や、セメントの粉や、鉄粉や、食品の粉や、石膏ボードの粉等も含む）が付着・堆積し易いダクト１内表面に配設される可撓シート１０と、ダクト１に穿設される開口部５と、この開口部５を開閉自在となるようにダクト１に装着される蓋板６とを備えたものである。
そして、前記可撓シート１０は、可撓性を有するシート材によって形成されると共に、その基端部分がダクト１或いは蓋板６に固定され、可撓シート１０の内表面に粉塵が付着して堆積したときには、蓋板６を作動せしめて、開口部５を開くと、開口部５から吸引される空気によって可撓シート１０全体が波打つように振動して、内表面に付着・堆積した粉塵を除去できるように構成したものである。
また、粉塵が付着・堆積し易いダクト１内表面としては、例えば、ダクト１のコーナー部２の外側壁内表面があり、この部分に可撓シート１０が配設される。
更に、遠隔操作可能な作動手段７を設けて、開口部５が開閉自在となるように蓋板６を作動せしめられるよう形成されている。 Hereinafter, the present invention will be described based on illustrated examples as follows.
The present invention is, for example, a dust removing device in a suction duct that can be used in an appropriate system using a sorting and separating system for building waste materials, a dust collection system, and other ducts.
This dust removing device is disposed on the inner surface of the duct 1 where dust (for example, sand, cement powder, iron powder, food powder, gypsum board powder, etc.) easily adheres and accumulates. A flexible sheet 10, an opening 5 formed in the duct 1, and a cover plate 6 attached to the duct 1 so that the opening 5 can be opened and closed are provided.
The flexible sheet 10 is formed of a flexible sheet material, and its base end portion is fixed to the duct 1 or the cover plate 6 so that dust adheres to the inner surface of the flexible sheet 10. When depositing, the lid plate 6 is operated to open the opening 5, and the entire flexible sheet 10 is vibrated by the air sucked from the opening 5 so that the dust adhered to and deposited on the inner surface is removed. It is configured so that it can be removed.
Moreover, as the inner surface of the duct 1 on which dust easily adheres and accumulates, for example, there is an inner surface of the outer wall of the corner portion 2 of the duct 1, and the flexible sheet 10 is disposed in this portion.
Furthermore, an operating means 7 that can be operated remotely is provided so that the lid plate 6 can be operated so that the opening 5 can be opened and closed.

前記ダクト１は、例えば、適宜金属材料によって適宜角筒状（或いは、その他の形状でも良い）に形成されている。しかも、そのコーナー部２にあっては、粉塵がなるべく付着し難いように比較的大きな曲面で構成されたものが好ましい。
また、ダクト１内表面には、粉塵等が付着し難くなるような適宜板材で覆ったり、コーティング処理等を施しておいても良い。 For example, the duct 1 is appropriately formed in a rectangular tube shape (or other shapes may be used) with a metal material. Moreover, it is preferable that the corner portion 2 is composed of a relatively large curved surface so that dust is hardly attached as much as possible.
In addition, the inner surface of the duct 1 may be appropriately covered with a plate material that makes it difficult to adhere dust or the like, or may be subjected to a coating process or the like.

前記開口部５は、例えば、矩形状を呈し、この開口部５を矩形状の蓋板６が自在に開閉できるよう形成されている。
尚、開口部５は、コーナー部２に於いてその吸引方向上流がわに配されるようにしてある。
また、開口部５は、比較的大きく構成して、点検口として利用できるようにしても良い。 The opening 5 has a rectangular shape, for example, and is formed so that the opening 5 can be freely opened and closed by a rectangular lid plate 6.
Incidentally, the opening 5 is arranged in the corner portion 2 so as to be upstream of the suction direction.
The opening 5 may be configured to be relatively large so that it can be used as an inspection port.

前記蓋板６は、例えば、図２から図６に示すように、蝶番等を介してダクト１に揺動自在となるように装着しても良いし、図７に示すようにダクト１に対して摺動自在となるように装着しても良い。尚、この蓋板６は、手動によって作動するように構成されたものでも良い。 For example, as shown in FIGS. 2 to 6, the lid plate 6 may be mounted so as to be swingable to the duct 1 via a hinge or the like, or may be attached to the duct 1 as shown in FIG. 7. It may be mounted so as to be slidable. The lid plate 6 may be configured to be manually operated.

前記作動手段７は、例えば、適宜エアーシリンダーを利用したものでも良いし、適宜油圧シリンダーを利用したものでも良いし、その他の適宜駆動手段を利用したものでも良く、蓋板６を確実に且つスムーズに作動（揺動或いは摺動）せしめられると共に、遠隔操作可能なものであれば良い。 The actuating means 7 may be, for example, an air cylinder as appropriate, a hydraulic cylinder as appropriate, or other appropriate drive means, and the lid plate 6 can be reliably and smoothly moved. Any device that can be operated (oscillated or slid) and can be remotely operated is acceptable.

前記可撓シート１０は、例えば、可撓性や強度や耐久性等を備えたゴムシートや、樹脂シートや、適宜複合材で構成されたシート等が利用され、その基端部分がダクト１や蓋板６に固定されるようになっている。すなわち、可撓シート１０は、通常は図２、図４の（ａ）、図５、図６、図７に示すように、ダクト１内の吸引力によってコーナー部２の外側壁内表面に沿うようになっており、開口部５が開いたときには、図３、図４の（ｂ）に示すように、開口部５から吸引されるダクト１外の空気によって（可撓シート１０とコーナー部２の外側壁内表面との間にダクト１外の空気が入り込むようになって）可撓シート１０がコーナー部２の外側壁内表面から大きく離れて、ダクト１内の吸引力とダクト１外からの空気の流れ込みとによって、全体が波打つように振動するよう構成されている。 As the flexible sheet 10, for example, a rubber sheet having flexibility, strength, durability, or the like, a resin sheet, a sheet composed of an appropriate composite material, or the like is used. It is fixed to the cover plate 6. That is, the flexible sheet 10 is usually along the inner surface of the outer wall of the corner portion 2 by the suction force in the duct 1 as shown in FIGS. 2, 4 (a), 5, 6, and 7. When the opening 5 is opened, as shown in FIGS. 3 and 4 (b), the air outside the duct 1 is sucked from the opening 5 (the flexible sheet 10 and the corner 2). The flexible sheet 10 is greatly separated from the inner surface of the outer wall of the corner portion 2, so that the suction force in the duct 1 and the outside of the duct 1 are separated from each other. The whole air is made to vibrate due to the inflow of air.

また、前述の如き粉塵除去装置を利用した本発明の粉塵除去方法について説明すると、以下の通りである。
先ず、通常時にあっては、システムのファン２５等によって発生するダクト１内の吸引力を利用して（或いは、吸引力を利用しなくても良い）粉塵が付着・堆積し易いダクト１内表面部分を可撓シート１０が覆うようになって、粉塵を可撓シート１０内表面に付着・堆積させる。
そして、この可撓シート１０内表面に付着・堆積させた粉塵の量が所定量となったときに（或いは、所定量となる前でも良いし、或いは、所定量となった後でも良い）、遠隔操作される作動手段７によって蓋板６を作動せしめる。
すると、ダクト１に穿設せしめてある開口部５を開き、開口部５から吸引されるダクト１外の空気によって可撓シート１０全体を波打つように振動せしめて、その内表面に付着・堆積した粉塵を除去する。 The dust removing method of the present invention using the dust removing device as described above will be described as follows.
First, during normal times, the inner surface of the duct 1 on which dust is likely to adhere and accumulate using the suction force in the duct 1 generated by the system fan 25 or the like (or the suction force may not be used). The portion is covered with the flexible sheet 10, and dust is adhered and deposited on the inner surface of the flexible sheet 10.
And when the amount of dust adhered to and deposited on the inner surface of the flexible sheet 10 reaches a predetermined amount (or may be before the predetermined amount, or after the predetermined amount), The lid plate 6 is actuated by the remotely operated actuating means 7.
Then, the opening 5 that has been drilled in the duct 1 is opened, and the entire flexible sheet 10 is vibrated so as to wave by the air outside the duct 1 sucked from the opening 5, and adheres and accumulates on the inner surface thereof. Remove dust.

尚、粉塵が付着・堆積し易いダクト１内表面部分としては、例えば、ダクト１のコーナー部２の外側壁内表面部分があり、この部分を可撓シート１０が覆うようにする。 In addition, as an inner surface part of the duct 1 in which dust easily adheres and accumulates, for example, there is an outer wall inner surface part of the corner portion 2 of the duct 1, and the flexible sheet 10 covers this part.

また、可撓シート１０の基端部分を作動手段７によって揺動する蓋板６に固定しておいた場合は、蓋板６の揺動と共に可撓シート１０が移動し、開口部５から吸引されるダクト１外の空気によって可撓シート１０全体がよりスムーズに波打つように振動せしめられて、その内表面に付着・堆積した粉塵をより確実に除去するようになる。 Further, when the base end portion of the flexible sheet 10 is fixed to the cover plate 6 that is swung by the operating means 7, the flexible sheet 10 is moved along with the swing of the cover plate 6, and is sucked from the opening 5. The air outside the duct 1 is vibrated so that the entire flexible sheet 10 undulates more smoothly, and dust attached and deposited on the inner surface thereof is more reliably removed.
