【産業上の利用分野】[Industrial applications]

本考案は、加工品又は試料を耐圧容器内に搬入して高温,高圧又は減圧下で処 理するオートクレーブに関する。 The present invention relates to an autoclave in which a processed product or a sample is carried into a pressure resistant container and processed under high temperature, high pressure or reduced pressure.

【0002】[0002]

【従来の技術】[Prior Art]

従来のオートクレーブは、図2に示すように、円筒形の耐圧容器1と、その開 口部2を閉塞する開閉扉3とから構成され、扉3を閉めた時に当該扉3の周縁部 4と当接する耐圧容器1の周縁部5に円環状の嵌合溝6を設け、その溝6にシリ コンゴム製のシールパッキン7を嵌め込み、このシールパッキン7によって耐圧 容器1と開閉扉3の間に隙間が生ずるのを防いで、耐圧容器1内の気密性を保つ ように成されている。 As shown in FIG. 2, a conventional autoclave is composed of a cylindrical pressure-resistant container 1 and an opening / closing door 3 that closes an opening 2 thereof, and when the door 3 is closed, a peripheral portion 4 of the door 3 is formed. An annular fitting groove 6 is provided in the peripheral edge portion 5 of the pressure-resistant container 1 that abuts, and a seal packing 7 made of silicon rubber is fitted into the groove 6, and a gap is provided between the pressure-resistant container 1 and the opening / closing door 3 by the seal packing 7. It is configured to prevent the occurrence of pressure and to maintain the airtightness inside the pressure resistant container 1.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところが、シールパッキン7を嵌合溝6に嵌め込む時に、シールパッキン7と 嵌溝6との間に多少の空気が閉じ込められて残ってしまい、この残留空気が耐圧 容器1内を高温に加熱した際に膨張し、シールパッキン7を嵌合溝6から押し出 そうとする圧力を生ずるため、開閉扉3を開ける際に、この空気の膨張圧によっ てシールパッキン7が嵌合溝6から外れてしまうという問題があった。 However, when the seal packing 7 was fitted into the fitting groove 6, some air was trapped and remained between the seal packing 7 and the fitting groove 6, and this residual air heated the inside of the pressure resistant container 1 to a high temperature. When the opening / closing door 3 is opened, the seal packing 7 is separated from the fitting groove 6 by the expansion pressure of the air when the opening / closing door 3 is opened. There was a problem that it would end up.

【0004】 また、耐圧容器1内を高圧にすると、嵌合溝6とシールパッキン7の間にも高 い圧力が加わるが、この嵌合溝6内にかかった高圧は、開閉扉3を開ける前に耐 圧容器1内を減圧しても完全には抜けきらず、外気圧より高い残留圧として溝内 に残るため、この残留圧によってシールパッキン7が嵌合溝6から押し出されて 脱落してしまうこともあった。Further, when the inside of the pressure-resistant container 1 is made to have a high pressure, a high pressure is also applied between the fitting groove 6 and the seal packing 7, but the high pressure applied to the fitting groove 6 opens the opening / closing door 3. Even if the pressure-resistant container 1 is depressurized before, it will not completely come out, and will remain in the groove as a residual pressure higher than the external pressure, so the seal packing 7 will be pushed out from the fitting groove 6 and fall off due to this residual pressure. It was sometimes lost.

【0005】 さらに、開閉扉3の周縁部4は、耐圧容器1内の気密性を保つために扉締付リ ング等によってシールパッキン7に対して非常に強い力で圧接されているので、 シールパッキン7の表面が扉3の周縁部4に付着してしまい、開閉扉3を開ける 際にシールパッキン7が扉3に引っ張られて嵌合溝6から外れてしまうこともあ った。Further, since the peripheral edge portion 4 of the opening / closing door 3 is pressed against the seal packing 7 with a very strong force by a door tightening ring or the like in order to maintain the airtightness in the pressure resistant container 1, The surface of the packing 7 may be attached to the peripheral portion 4 of the door 3, and when the opening / closing door 3 is opened, the seal packing 7 may be pulled by the door 3 and come out of the fitting groove 6.

【0006】 このように、従来のオートクレーブでは頻繁にシールパッキン7が嵌合溝6か ら外れていたため、その度ごとにシールパッキン7を嵌め直さなければならず、 手間がかかると共に、オートクレーブの稼動効率を著しく低下させるという大き な問題を生じさせていた。 そこで本考案は、開閉扉を開ける際に、シールパッキンが嵌合溝から外れるこ とのないオートクレーブを提供することを技術的課題としている。As described above, in the conventional autoclave, the seal packing 7 is frequently disengaged from the fitting groove 6, so that the seal packing 7 must be refitted each time, which is troublesome and the operation of the autoclave is difficult. It caused a big problem of significantly lowering efficiency. Therefore, it is a technical object of the present invention to provide an autoclave in which the seal packing does not come off from the fitting groove when the opening / closing door is opened.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

この課題を解決するために、本考案は、円筒形の耐圧容器と、その開口部を閉 塞する開閉扉とから成り、前記扉の閉塞時に当接する当該開閉扉と前記耐圧容器 の周縁部の何れか一方に、その周縁部に沿って円環状の嵌合溝が設けられ、当該 嵌合溝にシールパッキンが嵌め込まれているオートクレーブにおいて、前記嵌合 溝が、当該溝に穿設される吸気孔を介して、前記シールパッキンを溝内に吸着す る減圧装置に接続されていることを特徴とする。 In order to solve this problem, the present invention comprises a cylindrical pressure-resistant container and an opening / closing door that closes the opening of the pressure-resistant container. In an autoclave in which one side is provided with a ring-shaped fitting groove along the peripheral edge thereof and a seal packing is fitted in the fitting groove, the fitting groove is formed in the intake groove. It is characterized in that it is connected to a pressure reducing device for adsorbing the seal packing into the groove through a hole.

【0008】[0008]

【作用】[Action]

本考案のオートクレーブによれば、シールパッキンは、嵌合溝に穿設された吸 気孔を介して接続される減圧装置の吸引力によって溝内に吸着されているから、 従来のように嵌合溝内の残留空気の膨張圧や、残留圧によってシールパッキンが 溝から押し出されたり、或いはシールパッキンが開閉扉の周縁部に付着して引っ 張り出されたりして外れてしまうことが防止される。 According to the autoclave of the present invention, the seal packing is adsorbed in the groove by the suction force of the decompression device connected through the suction hole formed in the fitting groove. It is possible to prevent the seal packing from being pushed out of the groove due to the expansion pressure of the residual air in the inside or the residual pressure, or the seal packing from being attached to the peripheral edge of the opening / closing door and being pulled out.

【実施例】【Example】

以下、本考案の実施例を図面に基づいて説明する。 図1は、本考案によるオートクレーブの要部を示す概略図である。 図中1は円筒形の耐圧容器であり、その開口部2を閉塞する開閉扉3がヒンジ (図示せず)によって開閉自在に取付けられている。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing a main part of an autoclave according to the present invention. In the figure, reference numeral 1 is a cylindrical pressure-resistant container, and an opening / closing door 3 for closing the opening 2 is attached by a hinge (not shown) so as to be openable / closable.

【0010】 そして、開閉扉3を閉めた時に、当該扉3の周縁部4と当接する耐圧容器1の フランジ状の周縁部5には、その周縁部5に沿って円環状の嵌合溝6が設けられ ており、その嵌合溝6にはシリコンゴムで成形した環状のシールパッキン7が嵌 め込まれている。When the opening / closing door 3 is closed, the flange-shaped peripheral portion 5 of the pressure-resistant container 1 that comes into contact with the peripheral portion 4 of the door 3 has an annular fitting groove 6 along the peripheral portion 5. Is provided, and an annular seal packing 7 formed of silicon rubber is fitted into the fitting groove 6.

【0011】 また、嵌合溝6の底側に、耐圧容器1の外部に貫通する吸気孔8が穿設され、 当該吸気孔8は吸気管9を介して減圧装置としての真空ポンプ10に接続されて いる。 そして、吸気管9には、所定のタイミングで作動する電磁弁11と緊急用の手 動弁12が介装されている。 なお、本実施例における真空ポンプ10は、在来から、耐圧容器1内に搬入さ れる加工品Wを真空パックして処理を行うために配設されているものを流用した ものであり、調節弁13,14を介装した吸排気管15が耐圧容器1内に導入さ れている。An intake hole 8 penetrating to the outside of the pressure resistant container 1 is formed on the bottom side of the fitting groove 6, and the intake hole 8 is connected to a vacuum pump 10 as a pressure reducing device via an intake pipe 9. Has been done. The intake pipe 9 is provided with an electromagnetic valve 11 that operates at a predetermined timing and an emergency manual valve 12. The vacuum pump 10 according to the present embodiment is a conventional pump that is provided for vacuum-packing the processed product W carried into the pressure-resistant container 1 for processing, and is adjusted. An intake / exhaust pipe 15 having valves 13 and 14 interposed therein is introduced into the pressure resistant container 1.

【0012】 また、図示は省略したが、耐熱容器1内には、例えば本出願人にかかる特開昭 61−82833号公報に示されるように、開閉扉3と対向する位置にターボフ ァン等の循環ファンが配設されると共に、所定の位置に加熱器,冷却器,高圧気 体の供給口等が配設されている。Although not shown, in the heat-resistant container 1, for example, as shown in Japanese Patent Application Laid-Open No. 61-82833 filed by the present applicant, a turbo fan or the like is provided at a position facing the opening / closing door 3. This circulation fan is installed, and a heater, a cooler, a supply port for high-pressure gas, etc. are installed at predetermined positions.

【0013】 以上が本考案の一例構成であって、次にその作用について説明すると、まず、 開閉扉3を開放し、真空パック用の容器に封入された加工品Wを台車に載せて耐 圧容器1内に搬入する。The above is an example configuration of the present invention, and its operation will be described next. First, the opening / closing door 3 is opened, and the processed product W enclosed in the vacuum pack container is placed on a trolley to withstand pressure. Carry it into the container 1.

【0014】 そして、真空パック用の容器に吸排気管15のカップラーを接続した後に、開 閉扉3を閉め、扉締付リング等によって密閉状態にする。 次いで、真空ポンプ10を稼動し、調節弁13を開いて真空パック用の容器内 の空気を吸引して、加工品Wを真空パックする。 そして、調節弁13を閉じた後に、耐圧容器1内に高圧チッソガス,アルゴン ガス等の不活性気体を供給すると共に、加熱器により所要温度(例えば、60〜 500℃)に加熱し、循環ファンを作動させて加工処理を行う。Then, after connecting the coupler of the intake / exhaust pipe 15 to the container for the vacuum pack, the opening / closing door 3 is closed, and the container is closed by a door tightening ring or the like. Next, the vacuum pump 10 is operated, the control valve 13 is opened, the air in the container for the vacuum pack is sucked, and the processed product W is vacuum packed. Then, after closing the control valve 13, an inert gas such as high-pressure nitrogen gas or argon gas is supplied into the pressure-resistant container 1, and is heated to a required temperature (for example, 60 to 500 ° C.) by a heater to turn on the circulation fan. It is operated to perform processing.

【0015】 そして、所定の加工処理が終了すると、真空ポンプ10を再び稼動させ、電磁 弁11を開けてシールパッキン7を嵌合溝6の底側に吸引させてから、開閉扉3 を開放する。 このようにして扉3を開放すると、シールパッキン7は嵌合溝6内に吸着して いるから、従来のように溝6内の残留空気の膨張圧や、残留圧によってシールパ ッキン7が溝6から押し出されたり、或いは扉3の周縁部4に付着して引っ張り 出されて外れてしまうことが防止され、シールパッキン7を溝6に嵌め直す手間 が無くなり、オートクレーブの稼動効率が低下することもない。When the predetermined processing is completed, the vacuum pump 10 is operated again, the solenoid valve 11 is opened to suck the seal packing 7 to the bottom side of the fitting groove 6, and then the opening / closing door 3 is opened. .. When the door 3 is opened in this way, the seal packing 7 is adsorbed in the fitting groove 6, so that the seal packing 7 is moved to the groove 6 by the expansion pressure of the residual air in the groove 6 or the residual pressure as in the conventional case. It is also possible to prevent it from being pushed out of the door 3 or attached to the peripheral edge 4 of the door 3 and pulled out to remove it, eliminating the need to refit the seal packing 7 into the groove 6 and reducing the operating efficiency of the autoclave. Absent.

【0016】 なお、本実施例においては、耐圧容器1の周縁部5にシールパッキン7を設け る場合について説明したが、これに限らず開閉扉3の周縁部4に嵌合溝を設けて シールパッキン7を設ける場合にも適用できる。 また、真空ポンプ10については、本実施例のように加工品の真空パック用の ものを流用する場合に限らず、シールパッキン吸引用に別のポンプを配設しても 良いし、又減圧装置としては真空ポンプのほかにシリンダー装置や減圧タンクを 用いることもできる。 また、吸気孔8は、円環状の嵌合溝6に沿って複数設けるようにしても良い。In the present embodiment, the case where the seal packing 7 is provided on the peripheral edge portion 5 of the pressure resistant container 1 has been described, but the invention is not limited to this, and the fitting groove is provided on the peripheral edge portion 4 of the opening / closing door 3 to seal the seal. It can also be applied when the packing 7 is provided. Further, the vacuum pump 10 is not limited to the case where the vacuum pack of the processed product is used as in the present embodiment, and another pump may be provided for sucking the seal packing, or the decompression device. In addition to the vacuum pump, it is also possible to use a cylinder device or a decompression tank. Further, a plurality of intake holes 8 may be provided along the annular fitting groove 6.

【考案の効果】[Effect of the device]

以上述べたように、本考案によれば、シールパッキンは、嵌合溝に穿設された 吸気孔を介して接続される減圧装置の吸引力によって溝内に吸着されているから 、従来のように嵌合溝内の残留空気の膨張圧や、残留圧によってシールパッキン が押し出されたり、或いはシールパッキンが開閉扉の周縁部に付着して引っ張り 出されたりして外れてしまうことが防止され、シールパッキンを嵌合溝に嵌め直 す手間が無くなり、オートクレーブの稼動効率が低下することもないという優れ た効果がある。 As described above, according to the present invention, the seal packing is adsorbed in the groove by the suction force of the pressure reducing device connected through the air intake hole formed in the fitting groove. It is possible to prevent the seal packing from being pushed out by the expansion pressure of the residual air in the fitting groove or the residual pressure, or the seal packing from sticking to the peripheral edge of the opening / closing door and being pulled out. There is no need to refit the seal packing into the fitting groove, and there is an excellent effect that the operating efficiency of the autoclave does not decrease.
