Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically a zirconium material reaction vessel. Background Technology
[0002] In many industrial production fields such as chemical, pharmaceutical, and food industries, reaction vessels are a key reaction equipment and are widely used in various chemical reactions, material mixing, dissolution, heating and other processes. Zirconium reaction vessels are reaction vessels made using zirconium as the main material. They have excellent corrosion resistance and high temperature stability and are often used to synthesize various chemical substances, such as polymers, pharmaceutical intermediates, dyes and pesticides.
[0003] Traditional zirconium reactors typically employ jacketed heating, which involves installing a jacket around the reactor and introducing steam into the jacket to heat the materials inside. However, this heating method suffers from uneven heating, potentially leading to overheating of some materials while underheating others, thus affecting the quality and efficiency of the reaction.
[0004] Therefore, we have designed a zirconium-material reactor to address the aforementioned problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a zirconium-material reactor to solve the problems mentioned in the background art.

The output shaft of the speed reducer is located inside the housing. The top of the stirring shaft penetrates through the housing.

[0012] Compared with the prior art, this utility model provides a zirconium material reactor, which has the following beneficial effects:
[0013] The jacket installed on the outside of the zirconium reactor body works in conjunction with the coil on the internal stirring shaft to form a highly efficient heating system. Steam is introduced into the jacket through the steam inlet at the top to preheat the material inside the reactor as a whole. The first steam pipe in the cavity inside the stirring shaft can introduce steam into the coil embedded in the outside of the anchor-type stirring blade, so that the steam can act directly on the material, which greatly increases the heat exchange area, improves the heating efficiency, and makes the material more evenly heated, effectively avoiding local overheating or overcooling.
