Problems solved by technology

Therefore, the crystallization under high temperature and pressure cannot be obtained by using ordinary hydrothermal kettles.
[0004] In addition, the solubility measurement at high temperature requires complex and expensive special devices, so that the high temperature solubility data is extremely scarce, which not only affects industrial design and production, but also limits the in-depth study of phase equilibrium theory
If a common hydrothermal kettle is used for measurement, there will be a series of problems such as the difficulty of sampling the saturated solution at high temperature phase equilibrium, and the difficulty of directly observing the dissolution in the kettle.

Abstract

The invention relates to a screen-type hydrothermal kettle capable of separating solid and liquid, which is a kettle body with a top opening and a bracket placed on a base, an adjusting knob and an adjusting rod are arranged on the bracket, and the adjusting knob passes through a rotating shaft and a rotating gear. Connection, the side wall of the adjustment rod is provided with a straight tooth that meshes with the rotating gear, the lower end of the adjustment rod is provided with an outer magnetic fixing plate, the opening of the kettle body is provided with a top cover, and the inner cavity is provided with an inner container. There is an inner magnetic fixing plate fixed by the magnetic force of the outer magnetic fixing plate inside the inner tank, and at least one screen is arranged on the inner magnetic fixing plate, and the magnetic force generated by the outer magnetic fixing plate is used to absorb the inner magnetic material in the inner tank. Fixed plate, so as to fix the screen, control the movement of the outer magnetic fixed plate up and down, and then achieve the purpose of adjusting the height of the screen, and realize multiple sampling under different conditions at different times.

Description

technical field [0001] The invention relates to a reaction device in the chemical industry, in particular to a high-temperature and high-pressure hydrothermal kettle with a screen inside to realize solid-liquid separation. Background technique [0002] Polymorphism refers to the formation of crystals of the same molecule with different molecular arrangements in space, and one structure corresponds to one type of crystal form. In the field of medicine, different crystal forms mean different drug effects, and even some crystal forms have therapeutic effects, while others are toxic. Polymorphic products can be obtained by controlling the external crystallization conditions, for example, crystallization at different crystallization temperatures may result in different crystal forms. The higher the temperature, the greater the molecular motion, and the more unstable crystal forms may be formed. These metastable crystal forms can be transformed into stable crystal forms under cer...
