Description

Technical Field

[0001] The utility model relates to the technical field of autoclave cooling, in particular to a detachable cold-sealed autoclave cooling coil device. Background Art

[0002] Hydrothermal reactors are widely used in the simulation of mineral and material synthesis, physical and chemical reactions, biological growth and cultivation, and geological processes. During use, the maximum temperature needs to be heated to about 950 degrees Celsius. Under high temperature conditions, due to heat conduction, the temperature of the sealed end of the autoclave will also be correspondingly high. On the one hand, this will greatly increase the danger during the experiment. On the other hand, the pressure cap at the sealed end and the autoclave body will stick together due to high-temperature fusion, making it difficult to open the autoclave after the experiment. This reason greatly limits the safe use conditions of traditional cold-sealed autoclaves, resulting in traditional cold-sealed hydrothermal autoclaves usually only conducting simulation experiments below 800 degrees Celsius. In addition, the traditional cold-sealed autoclave has a wide hot spot constant temperature zone inside, which is only suitable for constant temperature experimental simulations, and cannot be used for experimental simulations of thermal diffusion with a temperature difference at both ends.

[0003] In the prior art, pressure is applied only through simple nuts and externally threaded pipe fittings to squeeze the rubber gasket between the connecting pipe and the externally threaded pipe to achieve sealing. The structure is simple, but the sealing effect cannot be effectively guaranteed, so improvement is needed. Utility Model Content
