4 results about "Large vessel" patented technology

Embodiments of a large container may include a container base and a circumferential container wall. An upper end of the wall is closed by a container cover in the form of a metal disc. An annular, circumferential support element is secured at an upper end region of the wall. The disc spans the upper open end of the container wall. A lower side of the disc is welded to the support element and / or to the upper end region of the container wall by a continuous first welding seam. An upper side and / or an edge of the disc is welded to the support element by a continuous second welding seam. The first and second weld seams have respective first and second roots which merge into one another or at least come together.

This utility model discloses a jade processing device for horizontal core cutting, including a base and a hollow drill cylinder disposed above the base; a turntable is disposed on the base, and a chuck is disposed on the turntable; a servo motor is disposed below the base; two upper through holes are opened opposite each other in the middle of the drill cylinder, and a lower through hole is opened below the upper through holes at the bottom of the drill cylinder; a first support plate is disposed between the two upper through holes at the top of the drill cylinder, and a tensioning mechanism is disposed on the first support plate; an external spray pipe for spraying water into the drill cylinder for cooling and lubrication is disposed above the drill cylinder. This utility model provides a jade processing device for horizontal core cutting, which performs horizontal cutting from the bottom of the drill, enabling the extraction of a complete cylindrical raw material from the belly of a jade carving vessel, achieving whole-piece core extraction, maximizing the value of the jade material, and this device can be widely applied to the production of large vessels requiring complete core extraction, enriching the jade carving techniques.
