【考案の詳細な説明】 〔産業上の利用分野〕 本考案はダスト分離用弁装置に関する。[Detailed explanation of the idea] [Industrial application field] The present invention relates to a valve device for dust separation.

排出に二重ダンパー２が用いられており、これは
焼結機排気集塵装置はブロワーで吸収されている
ため装置１内は一般に250〜2000mmAqの負圧を有
し、大気圧との間に圧力差があることによる。 For example, in a sintering machine exhaust dust collector 1, a double damper 2 is conventionally used to discharge dust, as shown in the side view of FIG. This is because the inside of the device 1 generally has a negative pressure of 250 to 2000 mmAq, and there is a pressure difference between it and the atmospheric pressure.

のである。 The double damper consists of two sets of dampers D 1 and D 2 installed above and below, as shown in the longitudinal cross-sectional view of Figure 3.
(There are conical, hemispherical, or flat plate structures.) Continuously repeating the operation of opening one side and closing the other side via the lever 6, shaft 7, and air cylinder 8. This allows dust to be discharged between the inside of the device where there is a pressure difference and the atmospheric pressure.

ストアツプを誘発している。 However, in such a structure, as shown in the longitudinal cross-sectional view of FIG. 1 or S 2 , this causes air leakage as shown by the arrow, and the mixture with dust causes wear due to vortices and circulation flows from the air leakage, and in this way, the damper and the contact of the seal surface worsens,
The function of maintaining airtightness is gradually lost, and as a result, the performance of the exhaust dust collector is significantly impaired, leading to a decline in operation and an increase in costs.

第１図はその縦断面図である。
When an embodiment of the present invention is explained with reference to the drawings,
FIG. 1 is a longitudinal sectional view thereof.
上図において、１０は上部ケーシング４の頂板

シール部１１とよりなり、シール部１１の下端に
は後記する上部ダンパーの円錐状当接面に密接す
るための円錐状当接面１３が形成されている。 In the above figure, reference numeral 10 denotes a double cylindrical sealing member that projects from the lower end of the hopper 5 on the top plate of the upper casing 4 and projects downward concentrically with the hopper 5.
The double cylindrical seal member 10 consists of a guide chute portion 12 in the shape of a tapered conical tube and a seal portion 11 in the shape of a tapered conical tube of approximately equal length surrounding the guide chute portion 12 concentrically with an appropriate gap. A conical abutting surface 13 is formed at the lower end of the damper 11 for coming into close contact with a conical abutting surface of an upper damper, which will be described later.
２０はほゞ円盤状の上部ダンパーで、その上面

ている。 Reference numeral 20 designates a substantially disk-shaped upper damper, and a surrounding edge 21 having a triangular cross section and having a conical contact surface for contacting the conical contact surface 13 of the seal portion 11 projects from the outer periphery of the upper surface thereof. The closer side is a cone-shaped recess 22, and the diameter of the circular bottom surface of the recess 22 is made slightly larger than the outer diameter of the lower end of the guide chute portion 12.
３０は上部ケーシング４の下端開口の下方に同
心的に突設された円錐ホツパー状シール部材で、
その下端開口端には球面状当接面３１が形成され
ている。 30 is a conical hopper-shaped sealing member protruding concentrically below the lower end opening of the upper casing 4;
A spherical abutment surface 31 is formed at the lower open end.
４０はシール部材３０の下端開口を着脱自在に
閉塞する凸曲球面を有する下部ダンパーである。 40 is a lower damper having a convex curved spherical surface that detachably closes the lower end opening of the seal member 30.
このような構造において、上部ダンパー２０、
下部ダンパー４はそれぞれ、第３図に示した上部
ダンパーD1、下部ダンパーD2と同様にそれぞれ
中心に先端部が固着されたレバー６の基端をシヤ
フト７を介して回動することにより開閉するよう
になつている。 In such a structure, the upper damper 20,
Each of the lower dampers 4 is opened and closed by rotating the base end of a lever 6 whose tip end is fixed at the center via a shaft 7, similarly to the upper damper D 1 and the lower damper D 2 shown in FIG. 3. I'm starting to do that.
そこで、まず下部ダンパー４０を閉状態とした
うえで、上部ダンパー２０を開き、下部ダンパー
４０上にダスト３を堆積させたのち、上部ダンパ
ー２０を閉じる。 Therefore, first, the lower damper 40 is closed, the upper damper 20 is opened, and the dust 3 is deposited on the lower damper 40, and then the upper damper 20 is closed.
その際、上部ダンパー２０の閉動作業中に上部
ダンパー２０上にはダスト３がホツパー５から連
続的に落下してくるが、ダスト３は凹所２２中に
落下して保持されるので、シール部１１の当接面
１３と上部ダンパー２０との間に落下することな
く、上部ダンパー２０によるダストのかみ込みを
防止することができる。 At this time, dust 3 continuously falls onto the upper damper 20 from the hopper 5 during the closing operation of the upper damper 20, but since the dust 3 falls into the recess 22 and is retained, the seal It is possible to prevent dust from being caught by the upper damper 20 without falling between the contact surface 13 of the part 11 and the upper damper 20.
次いで、上部ダンパー２０が全閉になつた時点
で、下部ダンパー４０を開き図示せざるベルトコ
ンベヤー上にダスト３を排出し、再び閉じること
によつて気密を保持しながらダストの排出を行
う。 Next, when the upper damper 20 is fully closed, the lower damper 40 is opened to discharge the dust 3 onto a belt conveyor (not shown), and is closed again to discharge the dust while maintaining airtightness.
これらの作動は図示せざる制御装置で一定時間
間隔をもつてくり返される。 These operations are repeated at regular time intervals by a control device (not shown).
本実施例では上部の仕切弁のみをダスト分離構
造としているが、当然のことながら更にダストの
排出を確実にするために、下部の仕切弁も、前者
と同一構造とすることが可能である。 In this embodiment, only the upper gate valve has a dust separation structure, but of course, in order to further ensure dust discharge, the lower gate valve can also have the same structure as the former.
このような構造によれば、ホツパーから連続的
に落下してくるダスト３は上部ダンパー２０で完
全に分離されるので、ダストが上部ダンパー２０

ーの漏風及び摩耗が防止され、長期の安定した機
能を確保し、保守費の低減、更には排気集塵装置
等の本体設備の効率向上に寄与することができ
る。 According to such a structure, the dust 3 continuously falling from the hopper is completely separated by the upper damper 20, so that the dust 3 is completely separated by the upper damper 20.
The damper is not caught between the damper and the seal portion 11, and the contact between the two is ensured. As a result, air leakage and wear of the damper are prevented, ensuring stable function over a long period of time, reducing maintenance costs, and can contribute to improving the efficiency of main equipment such as exhaust dust collectors.
