Abstract

The invention discloses an instant opening device for molten liquid in a high-temperature high-pressure container, and relates to an opening device of a high-temperature-resistant and high-pressure container. The instant opening device aims to solve the problem that the opening device in the existing high-temperature jetting preparation ceramic powder reaction is difficult to control the heat preservation time, and the high-temperature-resistant and high-pressure performance needs to be improved. The instant opening device comprises a reactor, a pressing piece, a nozzle, a nozzle support, a sealing pre-tightening piece, an upper sliding plate, a lower sliding plate and a dragging device, wherein two-stage stepped round holes are formed in the thickness direction of the bottom of the reactor, the nozzle support is arranged in the stepped circular hole, the pressure piece is arranged on the upper surface of the nozzle support, the nozzle is inserted into the insertion hole of the nozzlesupport, the upper sliding plate and the lower sliding plate lamination layer are arranged at the bottom of the reactor, and the upper sliding plate is driven by the dragging device to horizontally move. According to the design of the heat preservation structure of the instant opening device, high temperature of 1600-4000 DEG C and high pressure of 5-100 MPa can be withstood, the instant opening device is good in application state in the severe environment of the SHS high-temperature jetting process.

Description

technical field [0001] The invention relates to an opening device for a container resistant to ultra-high temperature and high pressure, in particular to an opening device applied in a reaction device for preparing ceramic powder by SHS high-temperature spraying. Background technique [0002] The first and crucial step in the preparation process of nanocomposite ceramics is the preparation of nanocomposite powders. After the powders are prepared, they are formed and sintered to form nanocomposite ceramics. The traditional powder preparation process is to mix single-phase ultrafine nano-powders by ball milling. The more advanced process method is to directly prepare uniformly mixed multi-phase powders by chemical methods. Common nanocomposite powder synthesis methods can be divided into three types: solid-phase method, gas-phase method, and liquid-phase method. [0003] The solid-phase method is mainly a mechanical mixing method, which is generally realized by high-energy ba...
