Sealing device suitable for object pressed under ultrahigh pressure and method

Abstract

The invention relates to an ultrahigh-pressure sealing device and a using method of the ultrahigh-pressure sealing device, in particular to a sealing device suitable for an object pressed under ultrahigh pressure and a using method of the sealing device. The sealing device is characterized in that the sealing device comprises an end cover, a magnetic movable block, an elastic assembly, an inner cylinder and an outer cylinder; the end cover is composed of an end cover shell and an end cover protrusion; the magnetic movable block is placed in the end cover protrusion; the elastic assembly is mounted between the magnetic movable block and the end cover shell; and the inner cylinder is mounted in the outer cylinder, and the inner cylinder and the outer cylinder are combined and then embedded in an annular groove defined by the end cover shell and the end cover protrusion. The sealing device has the advantages that the structure shape is not limited, product filling is rapid, mechanizationand automation are easy to achieved, vacuum packaging and non-vacuum packaging can be met through structure arrangement, and free selection is conducted according to the actual condition.

Description

technical field [0001] The invention relates to an ultra-high pressure sealing device and method, in particular to a sealing device and method suitable for ultra-high pressure treated articles. Background technique [0002] In ultra-high pressure processing (industry: such as powder metallurgy, electric carbon powder, ceramic powder and other ultra-high pressure shaping compression; agriculture and forestry: such as ultra-high pressure wood strengthening, grain, food ultra-high pressure sterilization, etc.), often in order to avoid the compressed medium and the subject Pressure products in direct contact require the use of sealed isolation devices. Traditional sealing structures often use clamps, threaded seals, or directly vacuumize thermoplastic seals. Clamps or threaded seals are only suitable for sealing cylindrical structures.

AI Technical Summary

Problems solved by technology

Traditional sealing structures often use clamps, threaded seals, or directly vacuumize thermoplastic seals. Clamps or threaded seals are only suitable for sealing cylindrical structures. If vacuum and square structures are required, clamps or threaded seals can be realized. No, but the vacuum thermoplastic seal can solve the shape problem, but every time the packaging is troublesome, the packaged material will be destroyed when it is removed and cannot be reused, and because of the packaging material, it is easy to be punctured by the edges and corners of the inner and outer items or friction. substances cause seal failure and thus compression strengthening failure
