DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

When the material in the reaction kettle 1 flows out through the vitreous enamel layer 21, a very high heat will be applied to the vitreous enamel layer 21, which may cause a porcelain explosion phenomenon. However, the metal mesh framework 22 can improve the overall impact strength of the vitreous enamel layer 21. The end of the kettle body outlet 2 is annularly and evenly provided with a notch 23. The kettle body outlet 2 is connected with a discharge pipe 3 at one end. The outer ring of the kettle body outlet 2 is fixedly installed with a locking structure 4 on one side.

[0023] Please refer to Figs. 1-3 The end surface of the discharge pipe 3 is annularly and evenly provided with a clamping tooth 31. The size of the clamping tooth 31 is matched with the size of the notch 23. When the discharge pipe 3 is connected with the kettle body outlet 2, the clamping tooth 31 is inserted into the notch 23. Then, the discharge pipe 3 is rotated clockwise by 45 degrees, so that the clamping tooth 31 is clamped on one side of the notch 23, achieving the effect of quick installation. A fluorine rubber sealing ring 32 is clamped between the end surface of the discharge pipe 3 and the end surface of the kettle body outlet 2, inside the inner ring of the clamping tooth 31. The working temperature of the fluorine rubber sealing ring 32 is between -26℃ and 282℃. Although it can still be used at a temperature of 295℃ for a short time, its service life will be shortened when the temperature exceeds 282℃. The most suitable temperature for use under dynamic sealing is between -15℃ and 280℃, and the low temperature can reach -40℃. It is worth mentioning that the fluorine rubber sealing ring 32 can be used under high vacuum conditions, below 1.33*10-7pa. A graphite gasket 33 is arranged between the end surface of the discharge pipe 3 and the end surface of the kettle body outlet 2. The graphite gasket 33 is a metal-wound graphite gasket.
