[0030] Embodiment. This embodiment aims to provide a self-stirring and vibrating dispersion integrated pipeline two-liquid mixer, and its main function is reflected in that it can re-mix and process the liquid initially mixed by the three-way structure to ensure the uniformity of the mixed slurry.

[0031] Refer to Figure 1 and Figure 2, including: a tee 1, a liquid mixing pipe 4, a main shaft 5, an impeller 6, a conical cylinder 7 and an annular frame 8. A support rod 2 is fixed inside the liquid outlet pipe of the tee 1. The end of the support rod 2 extends radially so that its end is fixed on the inner wall of the liquid outlet pipe. A sleeve 3 is fixed in the middle of the support rod 2. A bearing is nested inside the sleeve 3, which is not shown in the figure. The liquid inlet end of the liquid mixing pipe 4 is butted against the liquid outlet pipe of the tee 1 so that the liquid mixing pipe 4 is communicated with the tee 1. The diameter of the liquid mixing pipe 4 is larger than that of the liquid outlet pipe of the tee 1. While providing sufficient installation space for the conical cylinder 7 and the annular frame 8, it is also necessary to ensure the normal flow of the fluid in the liquid mixing pipe 4. The liquid outlet end of the liquid mixing pipe 4 is butted with a liquid delivery pipe 17 of the same size as the liquid outlet pipe of the tee 1 to ensure that it can be matched and butted with the next section of the pipeline.

[0032] Refer to Figure 2 , the main shaft 5 is horizontally placed inside the liquid mixing pipe 4 and is coaxially arranged with it. The front end of the main shaft 5 is rotatably arranged inside the sleeve 3, and the front end of the main shaft 5 is fixedly sleeved with the bearing inside the sleeve 3. The impeller 6 is rotatably and fixedly sleeved on the front end of the main shaft 5 near the liquid inlet end of the liquid mixing pipe 4 so that the impeller 6 is driven to rotate by the fluid flow, and then the main shaft 5 is driven to rotate by the impeller 6.

[0033] Refer to Figure 2 and Figure 3 , the conical cylinder 7 is centrally fixed inside the liquid mixing pipe 4, that is, a connecting rod 10 is fixed between the outer side of the conical cylinder 7 and the inner wall of the liquid mixing pipe 4. The conical cylinder 7 is near the liquid inlet end of the liquid mixing pipe 4. At the same time, the conical cylinder 7 is also sleeved outside the front end of the main shaft 5, and the tip of the conical cylinder 7 faces the impeller 6. Among them, since the tip of the conical cylinder 7 will reduce its size, the inner side of the tip of the conical cylinder 7 fits the outer surface of the main shaft 5, and the impact of the fluid on the conical cylinder 7 can be reduced through the tip, and the fluid can be better guided to the channel between the conical cylinder 7 and the liquid mixing pipe 4. The annular frame 8 is fixed inside the liquid mixing pipe 4, that is, the outer side of the annular frame 8 is also connected to the inner wall of the liquid mixing pipe 4 through the connecting rod 10. The annular frame 8 near the liquid outlet end of the liquid mixing pipe 4 is used to support the rear end of the main shaft 5.

[0034] Refer to Figure 2, a secondary shaft 9 parallel to the main shaft 5 is rotatably provided between the conical cylinder 7 and the annular frame 8. The main shaft 5 and the secondary shaft 9 are connected by a planetary gear transmission, so that the secondary shaft 9 rotates around the main shaft 5 while rotating itself. Specifically, there are a pair of planetary gears, which are respectively located inside the conical cylinder 7 and the annular frame 8. Tooth rings 11 are provided on the inner sides of the conical cylinder 7 and the annular frame 8. The planetary gear is composed of a driving wheel 12 and a driven wheel 13. The driving wheels 12 are fixedly sleeved on the outer parts of both ends of the main shaft 5, and both driving wheels 12 are located at the centers of their respective corresponding tooth rings 11. The driven wheel 13 is arranged between the driving wheel 12 and the corresponding tooth ring 11, and the driven wheel 13 is engaged with both the driving wheel 12 and the tooth ring 11 at the same time. Based on this, when the driving wheel 12 rotates, it can drive the driven wheel 13 to rotate itself, and make the driven wheel 13 revolve around the driving wheel 12 along the tooth ring 11. Among them, the driven wheels 13 in the conical cylinder 7 and the annular frame 8 are connected by the secondary shaft 9, that is to say, the secondary shaft 9 rotates synchronously with the driven wheel 13. Spiral blades 14 are distributed axially on the outer part of the secondary shaft 9. Thus, whether the secondary shaft 9 rotates or revolves, it can stir the mixed liquid.

[0035] In this embodiment, baffles 15 extend radially along the mutually corresponding surfaces of the conical cylinder 7 and the annular frame 8. The length of the baffle 15 is not greater than the radius of the driven wheel 13. The baffle 15 is to prevent the driven wheel 13 from disengaging between the driving wheel 12 and the tooth ring 11, so as to stabilize the motion state of the driven wheel 13.

[0036] In this embodiment, an ultrasonic transducer 16 is attached to the outside of the mixing liquid pipe 4. By transmitting acoustic vibrations into the mixing liquid pipe 4, the agglomerates inside the slurry in the mixing liquid pipe 4 can be dispersed, and the uniformity of the mixed slurry can be further improved.

[0037] During actual use, the slurry preliminarily mixed by the three-way pipe 1 will flow into the mixing liquid pipe 4. When the slurry enters the mixing liquid pipe 4, the impeller 6 is driven to rotate under the impact of the slurry, and the main shaft 5 rotates synchronously with the impeller 6. At this time, the planetary gears inside the conical cylinder 7 and the annular frame 8 rotate synchronously under the rotation of the main shaft 5, so that the secondary shaft 9 rotates around the main shaft 5 while rotating itself, thereby realizing the stirring of the slurry.

[0038] This embodiment can re-mix and process the liquid preliminarily mixed by the three-way structure, so that the uniformity of the two-liquid mixing reaches the best state, ensure the performance of the mixed slurry, and further ensure the reinforcement effect of grouting.

[0039] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model are within the scope of protection of the pending claims of the present utility model.
