Abstract
A molding machine for production of gas hydrate pellets under a high pressure in gas hydrate forming conditions, which is inexpensive through minimizing of the use of expensive mechanical seal. The molding machine comprises two forming rolls each fitted to a rotary shaft whose both ends are supported by bearings; a drive unit for rotating the forming rolls; a screw transfer unit for supplying powder to the forming rolls; and a high-pressure vessel, wherein the bearings, the rotary shaft and the forming rolls are all disposed in the high-pressure vessel.
Claims4
A gas hydrate compression molding apparatus comprising:
- a hopper which holds gas hydrate formed by the reaction of a raw material gas with a raw material water under a high pressure;
- a pair of forming rolls positioned at the lower portion of an opening part of the hopper;
- and a screw transfer unit which supplies gas hydrate powder in said hopper to said forming rolls, wherein said forming rolls are positioned in a high-pressure vessel which can pressurize thereof to said gas hydrate-forming pressure.
