て旋回しながら下降し、さらに円錐部(010)の下端
に達するまで数回転して上記ダストに遠心力を与える。(2) Second Conventional Example As shown in FIG. 11, a tangential flow type reverse flow cyclone is known. This cyclone consists of a cyclone body (08) consisting of a cylindrical part (09) and a conical part (010), and a cylindrical part (o9) which is made up of a container (02). An airflow containing dust flows in from the opening (011), descends while swirling along the inner wall of the cylindrical part (09), and then rotates several times until it reaches the lower end of the conical part (010), where it absorbs the dust. Gives centrifugal force.

られ、排風とダストとを分離するために用いられるもの
である。Due to this centrifugal force, the dust settles in the direction of the wall, is separated from the gas, and is carried to the container (02) by the downward flow and collected. The airflow from which the dust has been separated swirls upward within the cyclone body (08) and is discharged to the outside through the discharge port (06). This cyclone is installed in the exhaust hole of the dryer and is used to separate exhaust air from dust.

ィルタ(o7)に付着残留したダストや粉粒体を払い落
とさねばならず、その払い落し作業に手数がかかり面倒
なものであった。However, in the first conventional example having the above-mentioned configuration, the filter (07) is likely to be clogged with particulate matter, dust, etc., and may remain attached thereto in some cases. Therefore, even if you blow air in the opposite direction to the exhaust direction, the filter (07)
It is difficult to remove dust and powder particles that are clogged or stuck to the container, so it is necessary to remove the lid (03) and open the container (
Remove the filter (07) from the filter (02) and remove the filter (02) from the filter (02).
The dust and powder remaining on the filter (o7) had to be brushed off by applying a brush to the numerous holes in the filter (o7), and the removal process was time-consuming and troublesome.

うという問題点があった。In addition, in the first conventional example, due to the drawbacks mentioned above, it is necessary to brush the filter (o7) every time when changing the material to transport powders of different colors or materials. Therefore, it was time consuming and troublesome to change the material. Moreover, if the filter (07) was not brushed completely, the previous powder and granules remained attached, so when changing the material, the subsequent powder and granules were There was a problem that the previous powder or granular material was mixed in.

風が少ない場合も慣性力が弱くなり分離できなくなる。In addition, when the wall surface inside the cyclone body is worn away by powder and granules, holes may form.If the dust is light, the updraft will be greater than the inertial force, making it impossible to separate, and the I end up going outside. Furthermore, when there is little exhaust air, the inertial force becomes weak and separation becomes impossible.
分離効果を上げるためにはサイクロンを小型にすればよ
いが、圧力損失が大きくなるために有効ではなく、前述
したように大型化せざるを得ないものであった。In order to improve the separation effect, the cyclone can be made smaller, but this is not effective because the pressure loss increases, and as mentioned above, the cyclone has to be made larger.

出されるため、含塵ガスの捕集効率の向上が達成できる
ばかりか、周囲に粉塵を飛散させることがなくなる。し
かも筒状パンチング体が筒状濾布体の補強にもなる。(1) Since the dust collector is composed of a cylindrical punched body with a large number of pores and a cylindrical filter cloth inside this cylindrical punched body, the dust is filtered and collected by the cylindrical filter cloth. The clean gas is uniformly dispersed through the pores around the entire circumference of the cylindrical punching body due to the resistance of the cylindrical punching body and is released outside the system, which improves the collection efficiency of dust-containing gas. Not only that, it also prevents dust from being scattered around. Moreover, the cylindrical punching body also serves as reinforcement for the cylindrical filter cloth body.
(2) 集塵装置のガス入口はホッパドライヤー等の
ホッパの天蓋部にガス排出管を介して連通接続してある
から、含塵ガスと粉粒体とが混入して集塵装置内へ流入
するようなことがなく、分M浦集効率が向上され、ガス
の回収もホッパ内に残らず回収できる。(2) Since the gas inlet of the dust collector is connected to the canopy of a hopper such as a hopper dryer via a gas exhaust pipe, dust-containing gas and powder particles may mix and flow into the dust collector. There is no such problem, the collection efficiency is improved, and gas can be recovered without remaining in the hopper.

前述したようにこのような問題点をことごとく解消する
ことができる。It is also possible to connect the gas inlet of the dust collector to the side wall of a hopper such as a hopper dryer and take out the gas from the side, but in this case, dust-containing gas and powder particles may mix and collect. Dust flows into the device and normal separation and collection effects cannot be obtained.
This also resulted in a loss of powder and granules. As a solution to this problem, a wire mesh was placed at the gas outlet of the hopper to prevent contamination, but a new problem arose in that powder and granules adhered to the ml, making it difficult for the exhaust gas to be discharged. . As mentioned above, the present invention can completely eliminate these problems.
(3) 集塵装置には集塵受部が接続されているから
、含塵ガスや粉粒体が外部に飛散することもなく集塵受

掛は比重や粒径が小さい場合でも含塵ガスの分離捕集が
できる。(5) When the cross section of the cylindrical filter cloth is formed into a wave shape,
Since the filtration area for dust-containing gas is wide, the wind speed passing through the cylindrical filter can be slowed down, thereby reducing pressure loss and improving the collection efficiency. Dust-containing gas can be separated and collected even when the specific gravity and particle size are small.
(6) 筒状濾布体は筒状パンチング体に出し入れ自
在に内装するとか、筒状パンチング体を集塵装置本体に
着脱自在に設けるとかすると、濾布の目詰り時の濾布の
交換や清掃等が簡単にできる。(6) If the cylindrical filter cloth body is installed inside the cylindrical punching body so that it can be taken in and out, or if the cylindrical punching body is installed in the dust collector body in a detachable manner, it will be easier to replace the filter cloth when it becomes clogged. Cleaning etc. can be done easily.
