Background
When preparing electrode materials in a laboratory, a hydrothermal method is a common preparation method. The method comprises the steps of putting an aqueous solution reaction medium into a closed high-pressure reaction kettle, controlling the temperature at 120-220 ℃ and the pressure at 1MPa-1GPa, and carrying out chemical reaction on substances in the aqueous solution. And because the homogeneous nucleation and heterogeneous nucleation mechanisms of the hydrothermal reaction are different from the diffusion mechanism of the solid-phase reaction, a novel compound and a novel material which cannot be prepared by other methods can be created. Due to the advantages of simple operation, mild synthesis conditions, good uniformity and repeatability of the product and the like, the hydrothermal method is deeply researched and widely applied in a laboratory and has also realized large-scale development in the aspect of industrialization. Furthermore, with the rise of industries such as energy and catalysis, the application range of the hydrothermal method is increasing, and the hydrothermal method becomes one of the most important methods in the current material synthesis methods.
The hydrothermal reaction kettle is used as a place where the hydrothermal reaction occurs, consists of a stainless steel shell and a polymer lining (polytetrafluoroethylene or p-polyphenyl), is a reaction container capable of bearing considerable temperature and pressure, is common in the experimental research process, is produced with numerous novel materials through the hydrothermal reaction kettle at present, and is a good assistant for synthesis of laboratory materials. The reaction data can provide certain reference for subsequent industrial scale. However, the liner of the hydrothermal reaction kettle is composed of polymer components, so that the rigidity is poor, a kettle cover pressing sheet and a lower cover gasket of the reaction kettle are easily put together by mistake during operation by novice, the kettle cover pressing sheet cannot play a role in protecting the liner, and the liner is deformed under the conditions of high temperature and high pressure. The deformed lining is difficult to ensure good tightness, can cause failure of experiments, and is not tight in sealing due to overlarge pressure in the hydrothermal reaction process, and the reactants overflow to cause explosion danger. Therefore, it is very important to design an improved device for the kettle cover of the reaction kettle, which has a protection effect on the inner liner of the hydrothermal reaction kettle.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a reaction kettle cover improving device which protects the inner lining of a hydrothermal reaction kettle. The device has simple structure and easy operation.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a reation kettle cover improvement device to hydrothermal reaction kettle inside lining plays guard action, includes reation kettle cover, kettle cover clamp plate, packing ring and clamp plate fastening screw. The kettle cover fastening screw is in threaded connection with the kettle cover of the reaction kettle, the kettle cover is also in threaded connection with the kettle barrel, the kettle cover pressing plate is fixedly connected with the kettle cover fastening screw through a gasket and the pressing plate fastening screw, the pressing plate fastening screw is in threaded connection with the kettle cover fastening screw, the pressing plate fastening screw is screwed into the bottom of a threaded hole of the kettle cover fastening screw, and a certain gap is ensured to exist between the kettle cover pressing plate and the kettle cover fastening screw so that the kettle cover pressing plate can rotate freely relative to the kettle cover of the reaction kettle. Directly placing a gasket of a lower cover of the reaction kettle at the bottom of a cylinder of the reaction kettle; adding a proper amount of chemicals to be reacted into the lining cylinder, covering the lining cover, and putting the lining cover into the reaction kettle cylinder; connecting the kettle cover fastening screw, the reaction kettle cover, the kettle cover pressing plate, the gasket and the pressing plate fastening screw, then connecting the kettle cover fastening screw, the reaction kettle cover, the kettle cover pressing plate, the gasket and the pressing plate fastening screw with the reaction kettle barrel, clamping the reaction kettle barrel, forcibly rotating the reaction kettle cover to enable the kettle cover pressing plate to be in contact with the lining cover, and simultaneously screwing the reaction kettle cover and the reaction kettle barrel mutually; and then rotating the kettle cover fastening screw to enable the kettle cover pressing plate to be in close contact with the lining cover, and performing secondary fastening. The kettle cover pressing plate and the kettle cover of the reaction kettle can rotate relatively, so that mutual friction between the kettle cover pressing plate and the lining cover can be avoided; when the kettle cover fastening screw is rotated, the gasket and the pressing plate fastening screw sink, so that the kettle cover fastening screw and the kettle cover pressing plate are in contact with each other, and the purpose of fastening again is achieved.
The innovation points of the experiment are as follows: the kettle cover pressing plate and the reaction kettle cover which are originally separated are ingeniously connected together, so that the danger that a novice forgets to place or misplaces the reaction kettle cover pressing cover when the hydrothermal kettle is used can be avoided.
