及的気密の範囲に含まれる。FIG. 1 is a perspective view of the cleaning device of the present invention. The upper part of the main body 1 is opened to form an opening 2. Opening 2
A flexible plate 3 is attached to the periphery of the opening 2 so that the airtightness is maintained as much as possible between the cleaning object 7 (FIG. 2) represented by the belt of the belt conveyor. There is. The flexible plate 3 may be made of any material that can maintain airtightness as much as possible by bringing it into contact with an object to be cleaned. For example, rubber or cloth is used. Here, the flexible plate 3 may have a gap between the flexible plate 3 and the object to be cleaned due to wear due to contact with the object to be cleaned. It is included in the airtight range.
第１図においては、開口部２は本体１の上部に形成され
ているが、必ずしも上部である必要はなく、本体１の側
部に形成されていても良い。In FIG. 1, the opening 2 is formed in the upper portion of the main body 1, but it does not necessarily have to be the upper portion, and may be formed in the side portion of the main body 1.

The gas discharge port 4 is connected to a gas suction device (not shown), and the gas in the main body 1 is sucked by the gas suction device via the gas discharge port. The gas discharge port 4 can be provided at any position of the main body 1, but when provided on the side or the upper part of the main body 1, the powder removed from the object to be cleaned is deposited on the lower part of the main body 1. It is necessary to provide a powder discharge port at the bottom of the main body 1. On the other hand, when the gas discharge port 4 is provided in the lower portion or the bottom of the main body 1, the powder removed from the object to be cleaned is sucked together with the gas, so that there is no need to particularly provide the powder discharge port.
本考案においては、清掃装置の本体内に筒体５が一端を
外部に開口して設けられている。第１図には筒体の一端
が外部に開口しているが、両端が外部に開口していても
よい。筒体の設置位置は、被清掃物がベルトコンベアの
ベルトのように移動する場合には、移動方向に直角に、
即ちベルトの幅方向に配置される。In the present invention, the cylindrical body 5 is provided in the main body of the cleaning device with one end opened to the outside. Although one end of the cylindrical body is open to the outside in FIG. 1, both ends may be open to the outside. When the object to be cleaned moves like a belt of a belt conveyor, the installation position of the cylinder is perpendicular to the moving direction,
That is, they are arranged in the width direction of the belt.
筒体５は第１図に示したように１つであってもよく、ま
た、２つを平行に、或いは互いに直交するように配置さ
れていてもよい。The cylindrical body 5 may be one as shown in FIG. 1, or the two cylindrical bodies 5 may be arranged in parallel or orthogonal to each other.
上記の筒体５には、被清掃物に対向するようにスリット
６が設けられている。また、スリットにかえて孔が多数
設けられていても良い。A slit 6 is provided in the cylindrical body 5 so as to face the object to be cleaned. Further, a large number of holes may be provided instead of the slits.

物との距離は５〜20mmの範囲であることが好ましい。The slits 6 and the holes provided in the cylindrical body 5 exhibit the above-mentioned effects. Therefore, the width of the slit and the size and number of the holes may be determined according to the suction amount of gas so as to exert the above-mentioned action. Generally, the suction amount of gas is 1
In the case of ~ 20 m 2 / min, the width of the slit and the diameter of the hole are 0.5 ~ 1
It is preferably selected from the range of 0 mm, and the distance between the slit or hole and the object to be cleaned is preferably in the range of 5 to 20 mm.
（実施例） 第１図に示した清掃装置を第２図のようにセメント原料
粉体運搬用のベルトコンベアの復路始点に取付け気体吸
引装置による吸引量を６m3/minで24時間運転した。(Example) As shown in FIG. 2, the cleaning device shown in FIG. 1 was installed at the starting point of the return path of the belt conveyor for conveying the cement raw material powder, and the suction amount by the gas suction device was operated at 6 m 3 / min for 24 hours.
清掃装置のスリット幅は2mm、筒体の直径は75mm、スリ
ットとベルトコンベアとの距離は10mmであった。The slit width of the cleaning device was 2 mm, the diameter of the cylinder was 75 mm, and the distance between the slit and the belt conveyor was 10 mm.
その結果、ベルトコンベアに付着していたセメント原料
粉体は、本考案の清掃装置を通過後には完全に除去され
ていた。As a result, the cement raw material powder adhering to the belt conveyor was completely removed after passing through the cleaning device of the present invention.
一方、本考案の清掃装置を用いずにベルトコンベアを24

考案の清掃装置は被清掃物と非接触とすることができる
ために、摩耗による粉体除去効果の低下がなく、しかも
被清掃物を傷つけることもない。(Effect) According to the cleaning device of the present invention, the powder adhering to the object to be cleaned is blown off by the outside air having a high flow velocity flowing from the slits or holes provided in the cylindrical body, and the gas connected to the cleaning device is further removed. It is sucked by the suction device. Further, since the cleaning device of the present invention can be brought into non-contact with the object to be cleaned, the powder removing effect is not deteriorated by abrasion and the object to be cleaned is not damaged.
従って、本考案の清掃装置をベルトコンベアのベルトの
