[0033] The heating components are inserted into the reinforcing ring 21 and evenly distributed on the outer circumference of the reaction container 7 .

[0034] In some embodiments, the reinforcing ring 21 includes a plurality of reinforcing ribs 2, which are arranged along the periphery of the reaction container 7 and surround the periphery of the reaction container 7 to form the reinforcing ring 21. The reinforcing ring 21 is provided with a plurality of insertion holes matching the size of the heating component, and the heating component is inserted into the reinforcing ring 21 through the insertion holes.

[0035] In some embodiments, the heating component extends circumferentially along the reaction container 7 and folds back and forth in the height direction.

[0036] In some embodiments, the reinforcing ring 21 is preferably horizontally sleeved on the outer periphery of the reaction vessel 7, and the heating assembly 4 passes vertically through the jack and is fixed. The present application utilizes the reinforcing ring 21 to effectively fix the heating wire and prevent the reaction vessel 7 from being deformed by heat under long-term operation. The number, spacing, and size of the reinforcing rings 21 are not specifically limited here, and are matched and set according to the size of the reaction vessel 7. For example, two reinforcing rings 21 are set on the outer periphery of the reaction vessel 7, etc.

[0037] In some embodiments, the heating assembly 4 of the present application is evenly distributed on the outer periphery of the reaction container 7 in a reciprocating manner, so that the heating temperature inside the reaction container 7 is consistent, and matches with the reinforcement ring 21 to achieve a better strengthening and fixing effect. The number of reciprocating times is not limited here, and can be actually set according to the specific heating power and other parameters of the heating assembly 4.

[0038] In some embodiments, the heating component 4 of the present application includes multiple heating wires or thermocouples. The heating power and quantity thereof are not limited here. The power is controllable and is adjusted according to the reaction requirements.

[0039] In some embodiments, the device further comprises a cover body, which is arranged on the opening of the reaction container 7, and is provided with a plurality of reinforcing ribs 2. Furthermore, a plurality of reinforcing ribs 2 may be arranged horizontally and / or vertically on the cover body, and the reinforcing ribs 2 are used to enhance the strength of the cover body and prevent deformation of the cover body.

[0040] In some embodiments, Figure 2 As shown, at least one reinforcing rib 2 on the cover is provided with a hand-carrying hole 6. Preferably, two hand-carrying holes 6 are symmetrically provided, so that the operator can lift or put down the cover by grabbing the hand-carrying hole 6.
