本発明は、サイクロン装置の改良に係り、特に粗粒と微
粒の分離効率が改善されたサイクロン装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement of a cyclone device, and particularly to a cyclone device with improved separation efficiency between coarse particles and fine particles.
サイクロン装置は、一般には集塵や、気体と固形物との
分離に用いられるものであるが、粗砕粒と微粒との分離
にも好んで用いられている。Cyclone devices are generally used for dust collection and separation of gas and solid matter, but are also preferably used for separation of coarsely crushed particles and fine particles.
格別の動力装置も必要とせず、装置を静置した状態で簡
単に粗粒と微粒が分別できることはサイクロンの大きな
特徴であるが、在来の装置ではその分離効率は必ずしも
充分に満足できるものとは言えず、特に粗粒の補集率を
高めようとすれば、どうしてもその中に微粒が混入して
（ることが避けられなかった。A major feature of the cyclone is that it does not require any special power equipment and can easily separate coarse particles from fine particles while the device is standing still.However, with conventional devices, the separation efficiency is not always fully satisfactory. In particular, if we tried to increase the collection rate of coarse particles, it was inevitable that fine particles would be mixed in.
本発明者は、上記の問題点を解決すべく鋭意研究の結果
、従来の利点を損なうことなく粗粒と微粒の分離効率の
優れたサイクロン装置を完成するに至った。As a result of intensive research to solve the above-mentioned problems, the present inventor has completed a cyclone device that has excellent separation efficiency between coarse particles and fine particles without sacrificing the conventional advantages.

を上昇する気流を生じさせる給気手段を設けたことにあ
る。The gist of the cyclone device according to the present invention is that the descending leg provided at the lower part of the cyclone main body is provided with an air supply means for generating an airflow rising approximately in the center thereof.

向上するものである。With the above configuration, the airflow supplied from the air supply means and rising up the settling leg meat is applied to the coarse particles that are once separated and settle near the settling legs, thereby causing the coarse particles to adhere to the coarse particles. The fine particles containing the particles are released from the coarse particles, thereby improving the separation efficiency.
以下図面により本発明の詳細な説明する。 The present invention will be explained in detail below with reference to the drawings.

An introduction duct 6 introduces the particles into the chamber, an exhaust duct 6 discharges the particles together with the air flow, and an air supply pipe 7 that penetrates the side wall of the settling leg 3 and has an opening approximately in the center thereof.

ている。The main body of the cyclone has a conventional structure, and the lower part of the cylindrical main body 1 is connected to a hopper part 2 formed in a circular cone shape, and the coarse particles settled through settling legs 3 are placed at the lower center of the hopper part 2. It has a structure that allows it to be collected in the coarse grain collection box 4.

っている。The main body 1 is provided with an introduction duct 5 that opens approximately tangentially toward the inside of the main body on the side wall of its lower half, through which a mixture of coarse particles and fine particles is introduced together with the airflow, and the coarse particles are While rotating in the main body, accompanied by the air current, the particles collide with the inner wall surface of the main body, lose their buoyancy, and settle down, and are collected in the coarse particle collection box 4 from the hopper section 2 via the settling legs 3. On the other hand, the fine particles are discharged through the discharge duct 6 provided at the center of the upper wall of the main body 1 along with the airflow swirling inside the main body, thereby separating coarse particles and fine particles. There is.

を複数回繰り返すことも行なわれていた。Normally, in the above operation, the linear velocity and rising speed of the swirling airflow in the main body are appropriately selected depending on the physical properties of the coarse particles and fine particles to be separated to achieve the purpose. In some cases, in order to achieve a sufficient separation effect, the separated particles are again introduced into another cyclone device and the same separation operation is repeated several times.
本発明者は、従来のサイクロン装置に於ける上記の如き

位置にこれに対向する気流を積極的に与えることにより
、一旦分離された粗粒からこれに付着している微粒部分
だけを再度分離することに成功し、本発明を完成したも
のである。The inventor of the present invention has discovered that in the above-mentioned operation of a conventional cyclone device, if the speed of the airflow is set low in order to carefully collect the coarse particles, When we focused on and studied this, we found that fine particles were attached to the coarse particles that had once settled in the center of the hopper, and that these coarse particles did not necessarily all lose the energy of their swirling motion. It was discovered that fine particles adhering to the particles can be ejected even during the period of the swirling sedimentation movement.Therefore, an air current opposing the coarse particles is actively directed to the position where the coarse particles are settling. By giving this method, the present invention was completed by successfully reseparating only the fine particles adhering to the coarse particles once separated.
即ち、本発明に係るサイクロン装置に於ては、微粒を伴

３の部分に、図面に示す如く、例えば給気管７の如き給
気手段を設け、上記沈降中の粗粒に対向する気流、即ち
沈降脚肉を上昇する気流を与えるように構成しである。That is, in the cyclone device according to the present invention, as shown in the drawing, an air supply such as an air supply pipe 7 is provided in the part of the settling leg 3 through which coarse particles that have settled together with fine particles pass through. Means is provided to provide an airflow that opposes the settling coarse particles, that is, an airflow that ascends the settling leg meat.
この場合、沈降脚３内にその全断面を一様に上昇する気
流を形成させることは必ずしも得策ではない。何故なら
そのような気流は粗粒の旋回運動を妨げることになり、
その結果粗粒部分の逸失を招きがちであり、また粗粒か
ら分離した微粒は運動エネルギーが小さいから旋回気流
中では中央部に比較的密に存在するので中央部について
だけ上昇気流を形成させれば充分に目的を達成できるか
らである。In this case, it is not necessarily advisable to form an airflow that uniformly ascends over the entire cross section of the sinking leg 3. This is because such air currents impede the swirling movement of coarse particles.
As a result, the coarse particles tend to be lost, and since the fine particles separated from the coarse particles have low kinetic energy, they are relatively densely present in the center of the swirling airflow, so an upward airflow can only be formed in the center. This is because it is sufficient to achieve the purpose.
沈降脚の中央部分に上昇気流を形成させる手段としては
種々の態様があり得る。沈降脚の壁を貫通して中央部で
上向きに開口する給気管７を設けることは最も簡単な構
造である。There may be various embodiments as means for forming an upward air current in the central portion of the sinking leg. The simplest construction is to provide an air supply pipe 7 which penetrates the wall of the lowering leg and opens upward in the center.

じ慝から、本発明の効果は充分に発揮されるものである
。Alternatively, if attention is paid to precision in construction and operation, instead of providing the air supply pipe 7, it is possible to simply make two small holes 8 (only one is visible in the figure) at opposite positions in the side wall of the sinking leg 3. It's good to just leave it early. In other words, if the entire cyclone device has a sufficiently negative pressure on the side where the fine particles are discharged than on the side where the mixed particles are introduced, the air introduced from a pair of opposing small holes collides at the center of the settling legs and rises there. Since airflow is generated, the effects of the present invention are fully exhibited.

通り、沈降脚の略中央部に上昇気流を生じさせる給気手
段を設けるという極めて単純なものであるから、これを
使用目的に応じて適宜設計変更することにより、具体的
には極めて広い応用範囲を有するものである。As stated in the claims, the essential constituent elements of the present invention are extremely simple, such as providing an air supply means for generating an upward airflow approximately in the center of the descending leg. Specifically, by appropriately changing the design, it has an extremely wide range of applications.

である。That is, for example, as shown in FIG. 1, it is possible to achieve a sufficient effect by simply providing an air supply means in the sinking leg of one cyclone; however, as shown in FIG. It is also possible to implement the present invention.
第２図中、上段のサイクロンの各構成要素のうち第１図
と同一の構成要素については第１図と同一の番号を付し
、また下段のサイクロンの構成要素中、上段のサイクロ

Components are indicated by the same number with a prime sign (') added.
第２図に示す如き多段構成であると、粗粒と微粒の分離
効果が増大すると共に、上段側のサイクロンの負荷の低
減に有効である。A multistage configuration as shown in FIG. 2 increases the effect of separating coarse particles and fine particles, and is effective in reducing the load on the cyclone on the upper stage side.

値は本発明の構成要件ではない。In addition, in the cyclone device according to the present invention, the flow rate and flow rate of the updraft that should be formed approximately at the center of the settling leg can be selected from a wide range depending on the properties and amounts of coarse particles and fine particles to be separated. chosen, decided. Of course, these values will vary depending on the size of the device itself. Therefore, the numerical value is not a constituent feature of the present invention.
