[0016] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0017] A twin-shaft stirring paddle reactor, such as Figure 1 , including a main frame 1, a container 2, a stirring device 5 and a driving assembly 6. The main frame 1 is welded by angle steel and channel steel. The container 2 is placed inside the main frame 1. In order to facilitate operations such as cleaning and material removal, the container 2 is detachably installed on the main frame 1. Specifically, a container support portion 11 is provided on the main frame 1. In this embodiment, the container support portion 11 adopts two groups of arc-shaped frames. The container support portion 11 is connected to the main frame 1 by bolts to form a fixed support for the container 2. When filling, filling is carried out through the upper part of the container 2. A discharge valve body 21 is provided at the bottom of the container 2.

[0018] like Figure 2The stirring device 5 includes an inner stirring shaft 52 and an outer stirring shaft 51, the outer stirring shaft 51 and the inner stirring shaft 52 are nested, the driving assembly 6 is connected to the inner stirring shaft 52 and the outer stirring shaft 51, one end of the inner stirring shaft 52 extends from one end of the outer stirring shaft 51, a main stirring blade 53 is arranged on the outer stirring shaft 51, and a stirring frame 54 and an auxiliary stirring blade 55 are arranged on the inner stirring shaft 52. At least two groups of main stirring blades 53 are arranged in the axial direction, and the auxiliary stirring blades 55 and the main stirring blades 53 are staggered. When stirring, the inner stirring shaft 52 and the outer stirring shaft 51 can rotate at different speeds or in different directions For stirring, both ends of the inner stirring shaft 52 extend from both ends of the outer stirring shaft 51, a number of bearings are arranged in the outer stirring shaft 51 and connected to the inner stirring shaft 52, and a rotating seal is installed between the outer stirring shaft 51 and the inner stirring shaft 52 to prevent materials from entering. The driving component 6 includes a driving motor, and a driving motor can be arranged to drive the inner stirring shaft 52 and the outer stirring shaft 51 respectively through a transmission system (such as a gear transmission system). In this embodiment, the driving component 6 includes two stirring motors, namely an inner shaft driving motor 62 and an outer shaft driving motor 61, which drive the inner stirring shaft 52 and the outer stirring shaft 51 respectively.

[0019] The setting of double-axis stirring can make the material stirring efficiency higher, thereby improving the reaction efficiency. The staggered stirring blades can achieve a better shearing effect on the material. In addition, the setting of the inner and outer double axes can achieve a higher degree of integration. The traditional double-axis stirring has a stirring shaft on the upper side and a stirring shaft installed at the bottom of the container, which leads to a complex container structure and is difficult to clean and has problems such as poor and incomplete material discharge. This solution solves the problem of complex container structure caused by the traditional upper and lower double-axis stirring.

[0020] Further, in order to facilitate the removal of the container 2, the driving assembly 6 is installed on the bracket 4, and the bracket 4 is moved upward to remove the stirring device 5 from the container 2. Preferably, a lifting assembly 3 is installed on the main frame 1, and the lifting assembly 3 can use a cylinder or a hydraulic cylinder to achieve automatic lifting without manual lifting. The lifting assembly 3 is connected to the bracket 4, and a guide rod 41 is installed on the bracket 4. A guide sleeve 12 is provided on the main frame 1. When the bracket 4 is lifted or lowered, the guide rod 41 and the guide sleeve 12 play an effect of maintaining the lifting stability.
