연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A manway gate assembly couples to a tank and provides a liquid tight seal. The manway gate assembly includes a gate selectively slideable in a first linear direction between an open position, a closed position, and/or an intermediate position between the open position and the closed position. The manway gate assembly includes one or more locking members arranged adjacent to the gate and moveable between a locked position and an un-locked position. When in the locked position, the one or more locking members apply a biasing force to the gate in a second l...

1. A container comprising: a tank for holding a product; anda gate assembly coupled to the tank, the gate assembly comprising: a gate slideably disposed in a first plane adjacent to a surface of the tank, the gate to slideably displace in the first plane along the surface of the tank between an open position and a closed position; andone or more locking members having a longitudinal axis movably disposed in a second plane parallel to the first plane, the one or more locking members being movable between a locked position and an un-locked position, and the one or more locking members comprising one or more cams, the one or more cams including a lobe portion,wherein the lobe portion of the one or more cams applies a biasing force to the gate in a direction perpendicular to the first and second planes to seal the gate to the surface of the tank in the locked position. 2. The container of claim 1, wherein the gate comprises a planar rectangular shaped plate. 3. The container of claim 1, wherein the one or more locking members are rotatable in the second plane parallel to the first plane between the locked position and the un-locked position. 4. The container of claim 3, wherein the gate assembly further comprises a frame arranged around the gate, the frame comprising one or more bearing surfaces, and the lobe portion of the one or more cams to bear on the one or more bearing surfaces to apply a biasing force to the gate perpendicular to the first and second planes to seal the gate to the surface of the tank in the locked position. 5. The container of claim 4, wherein the gate assembly further comprises: a linear actuator coupled to the frame and to the gate, the linear actuator to selectively slide the gate between the open position, the closed position, or an intermediate position between the open position and the closed position. 6. The container of claim 3, wherein the gate assembly further comprises: a rod connected to the one or more locking members to rotate the one or more locking members between the locked position and the un-locked position. 7. The container of claim 6, wherein the gate assembly further comprises: an actuator connected with the rod connected to the one or more locking members to rotate the one or more locking members between the locked position and the un-locked position. 8. The container of claim 1, further comprising a scraper blade assembly rotatably coupled to a bottom surface of the container to displace solids deposited on the bottom surface of the container through the gate assembly when the gate is in the open position or an intermediate position between the open position and the closed position. 9. The container of claim 1, wherein the gate is movable in the first plane along the surface of the tank to an intermediate position between the open position and the closed position. 10. The container of claim 1, wherein the container comprises a fermentation tank. 11. A tank comprising: a top surface;a bottom surface opposite the top surface, the bottom surface having a non-zero slope relative to a horizontal support surface;a wall coupled to and between the bottom surface and the top surface;an aperture arranged in the wall of the tank proximate to the lowest portion of the slope of the bottom surface of the tank, the aperture comprising a sealing surface; anda manway gate assembly arranged around the aperture through which to empty a product held in the tank, the manway gate assembly comprising: a gate arranged adjacent to the sealing surface of the aperture, the gate to selectively slide along the sealing surface of the aperture between an open position and a closed position; andone or more locking members rotatably disposed adjacent to the gate, each of the one or more rotatable locking members to rotate about a longitudinal axis of the respective one or more rotatable locking member between a locked position and an un-locked position, and the one or more rotatable locking members comprising one or more cams, the one or more cams including a lobe portion,wherein the lobe portion of the one or more cams applies a biasing force to the gate in a direction perpendicular to the sealing surface of the aperture to seal the gate to the sealing surface of the aperture in the locked position. 12. The tank of claim 11, wherein the manway gate assembly further comprises a frame arranged around the gate, the frame comprising one or more bearing surfaces, and wherein the lobe portion of the or more cams to bear on the one or more bearing surfaces to apply a biasing force to the gate in the direction perpendicular to the sealing surface of the aperture to seal the gate to the sealing surface of the aperture in the locked position. 13. The tank of claim 11, wherein the manway gate assembly further comprises: a linear actuator coupled to the frame and to the gate, the linear actuator to selectively slide the gate between the open position, the closed position, or an intermediate position between the open position and the closed position. 14. The tank of claim 11, wherein the manway gate assembly further comprises a rod connected to the one or more locking members to rotate the one or more rotatable locking members between the locked position and the un-locked position. 15. The tank of claim 11, further comprising a blade rotatably coupled to the bottom surface of the tank to displace solids deposited on the bottom surface of the tank through the gate when the gate is in the open position or an intermediate position between the open position and the closed position. 16. A manway sliding gate assembly comprising: a gate to selectively slide in a first linear direction between an open position and a closed position; andone or more locking members movably arranged adjacent to the gate, the one or more locking members being movable between a locked position and an un-locked position, and the one or more locking members comprising one or more cams, the one or more cams including a lobe portion,wherein in the locked position the lobe portion of the one or more cams applies a biasing force to the gate in a second linear direction perpendicular to the first linear direction. 17.
