[0027] The technical solutions 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.
[0028] Please refer to Figures 1-9 A continuous mixing building block type paddle comprises a mandrel 1 and multiple groups of paddle assemblies; the multiple groups of paddle assemblies are sequentially connected on the mandrel 1; the paddle assembly comprises a 45° paddle 2, a 0° paddle 3 and a double-angle paddle 4, and the 45° paddle 2, the 0° paddle 3 and the double-angle paddle 4 are sequentially connected on the mandrel 1. The head of the mandrel 1 is connected with a top head bolt to limit and fix the paddle assembly.
[0029] Please refer to Figure 3 , 4 The 45° paddle 2 comprises a first paddle sleeve 5 and two first 45° blades 6, and the two first 45° blades 6 are respectively connected on the two sides of the outer wall of the first paddle sleeve 5.
[0030] Please refer to Figure 5 , 6 The 0° paddle 3 comprises a second paddle sleeve 7 and two first 0° blades 8, and the two first 0° blades 8 are respectively connected on the two sides of the outer wall of the second paddle sleeve 7.

[0032] Please see Figure 2 The outer wall of the spindle 1 is hexagonal, and the inner walls of the first blade sleeve 5, the second blade sleeve 7, and the third blade sleeve 9 are all hexagonal holes. The first blade sleeve 5, the second blade sleeve 7, and the third blade sleeve 9 are all fitted onto the outer wall of the spindle 1.
[0033] Specifically, the 45° blade 2 mainly conveys materials forward, primarily generating axial mixing, while the 0° blade 3 mainly stirs materials radially, also primarily generating radial mixing. The 45° blade 2 has the strongest axial mixing capacity and the weakest radial mixing capacity; the double-angle blade 4 has moderate axial and radial mixing capacity; the 0° blade 3 has no axial mixing capacity but the strongest radial mixing capacity. By arranging and combining these three types of blades, the operating conditions of different process formulations and material characteristics can be fully met.
[0034] Specifically, the end part of the spindle is cylindrical and cooperates with the support. The main body of the spindle 1 is an external hexagonal body, which cooperates with the internal hexagonal body of the sleeve of each blade. The hexagonal shape can play the role of positioning and transmission.
[0035] Please see Figure 9 The first 45° blade 6 can be four blades, equidistantly connected to the outer wall of the first blade sleeve 5. This increases axial mixing capacity.

[0037] Step S1: The 45° blade 2, the 0° blade 3, and the double-angle blade 4 are sequentially fitted onto the mandrel 1 in a group until they are fitted onto the end of the mandrel 1.
[0038] Step S2: Thread a top bolt to the end of the mandrel 1 to restrict and fix the blade sleeve.
[0039] Different orders of the 45° paddle 2, 0° paddle 3 and double-angle paddle 4 can be assembled according to different materials. The 45° paddle 2 mainly functions to forwardly convey the materials and mainly generates axial mixing, and the 0° paddle 3 mainly functions to radially stir the materials and mainly generates radial mixing. The 45° paddle 2 has the strongest axial mixing ability and the weakest radial mixing ability; the double-angle paddle 4 has moderate axial mixing ability and moderate radial mixing ability; the 0° paddle 3 has no axial mixing ability and the strongest radial mixing ability; by arranging and combining the above three kinds of paddles, different process formulations and different material characteristics can be fully met.

The continuous mixing reduces intermediate steps such as transfer and caching, so that the automation degree and production efficiency can be improved. The continuous mixing can reduce the number of production personnel and the contact between the production personnel and the materials, so that the pollution risk is reduced.
