[0002] High viscosity reactor is a reaction equipment specially designed for processing high viscosity materials. This type of reactor is widely used in chemical, biological, food and other fields. Especially in the process of high viscosity material reaction that requires high temperature, high pressure or special stirring conditions, its importance is particularly prominent.

[0003] At present, a spiral ribbon is arranged on the outer periphery of the discharge screw of a high viscosity reactor, and the ribbon is used to transport materials in the screw sleeve. In order to improve the discharge efficiency of the reactor, the discharge port at the lower end of the reactor is a conical structure with the large end at the top and the small end at the bottom. In order to adapt to the structural characteristics of the discharge port, the upper end of the screw is equipped with a conical ribbon structure with a large upper periphery and a small lower periphery through a key and a keyway. The power of the screw is transmitted by the key to make the upper end ribbon rotate. This split screw ribbon installation structure has the following problems:

[0004] (1) Since there may be a gap between the key and the keyway during assembly or during operation, it will have an adverse effect on the overall running balance of the screw, and there is a risk of wear and jamming;
