Description

Technical Field

[0001] The utility model relates to the technical field of road grouting repair, in particular to a mixer for geopolymer grouting materials. Background Art

[0002] With the rapid development of modern grouting repair technology, road grouting material mixers, as key equipment in the road grouting repair process, play a vital role in the mixing quality of grouting materials. However, in the actual road repair process, after the geopolymer grouting material is stimulated by alkali, it will gradually become viscous during the mixing process due to the influence of the environment, mixing equipment and the characteristics of the material itself, and the phenomenon of thin top and thick bottom will appear in the mixer, which will seriously affect the effect of road grouting repair. Therefore, it is particularly important to develop a mixer for geopolymer grouting materials.

[0003] At present, there are relatively few mixers for early-setting materials on the market, and they cannot alleviate the problem of thin materials at the top and thick materials at the bottom in the mixer. Most mixers can only improve the uniformity of the mixed materials by controlling the amount of materials mixed, which will seriously affect the efficiency of road grouting repair during actual construction.

[0004] To solve these problems, mixers are developing towards high speed, large capacity and more uniform material mixing. With the increasing demand for the quality of mixed materials in actual projects, mixers must not only have the above characteristics, but also have better applicability and ease of use. In addition, the development of intelligent control technology also makes it possible for mixers to be intelligent.

[0005] In view of the shortcomings of the existing technology, this utility model patent proposes a new type of mixer. The mixer adopts a unique design structure, which significantly improves the speed and capacity of the mixer, and will effectively alleviate the problems of thin top and thick bottom in the mixing materials in the mixer. At the same time, its good applicability and ease of operation ensure the stable operation of the mixer under different construction conditions, and improve the repair effect of geopolymer grouting materials in actual projects. The proposal of this innovative solution is of great significance to improving the efficiency and quality of road grouting repair, and is an indispensable part of road disease grouting repair operations. Utility Model Content

[0006] The purpose of the embodiment of the utility model is to provide a mixer for geopolymer grouting materials, which is used to solve the current problems of insufficient mixing, thin upper part of the material and thick lower part.

[0007] A mixer for geopolymer grouting materials comprises a mixing barrel, a mixing assembly is arranged in the mixing barrel, and the upper end of the mixing assembly is connected to a power assembly; the mixing assembly comprises a secondary rotating shaft and a mixing fan blade; the secondary rotating shaft is parallel to the axis of the mixing barrel, and at least two mixing fan blades are connected to the secondary rotating shaft; the power assembly comprises a revolution power assembly and a rotation power assembly; the output end of the revolution power assembly is connected to the secondary rotating shaft, and the output end of the rotation power assembly is connected to the upper end of the secondary rotating shaft.

[0008] The mixing fan blades revolve around the center in the mixing barrel and also rotate on their own through the secondary rotating shaft. The simultaneous rotation and revolution can effectively ensure the adequacy of the mixing effect and expand the mixing range, effectively avoiding the problem of the material being thin at the top and thick at the bottom.

[0009] Preferably, a discharge port is provided at the bottom of the mixing barrel, and a rotating wheel is provided at the discharge port. The rotating wheel at the discharge port can be used to perform secondary stirring while discharging the material, so as to ensure that the grouting material is more uniform.

[0010] Preferably, the revolution power assembly includes a main rotating shaft motor, a main rotating shaft reducer, a main rotating shaft transmission gear assembly, a main rotating shaft, and a main-secondary shaft connecting plate; a main rotating shaft motor is arranged in the control console, the output end of the main rotating shaft motor is connected to the main rotating shaft reducer, the main rotating shaft reducer is connected to the main rotating shaft through the main rotating shaft transmission gear assembly, and the main rotating shaft is connected to the secondary rotating shaft through the main-secondary shaft connecting plate.

[0011] The revolution power assembly is used to drive the fan blades to revolve. The main rotating shaft coincides with the axis of the mixing barrel, and the secondary rotating shaft is connected by the main and secondary shaft connecting plates. The secondary rotating shaft is located between the axis of the mixing barrel and the barrel wall. The main rotating shaft motor rotates, driving the secondary rotating shaft to move in a circle around the main rotating shaft, thereby achieving the purpose of the fan blades to revolve.

[0012] Preferably, the self-rotation power assembly includes a secondary rotating shaft motor, a secondary rotating shaft reducer, and a transmission gear assembly; the secondary rotating shaft motor is arranged on the control console, the output end of the secondary rotating shaft motor is connected to the secondary rotating shaft reducer, and the secondary rotating shaft reducer is connected to the secondary rotating shaft through the secondary rotating shaft transmission gear.

[0014] Preferably, the main rotating shaft transmission gear assembly includes a transverse bevel gear and a vertical bevel gear; the transverse bevel gear and the vertical bevel gear are meshingly connected.

[0015] Through the meshing connection of the horizontal bevel gear and the vertical bevel gear, the transmission direction can be changed by 90 degrees, making the structure of the entire device more compact.

[0016] Preferably, the secondary rotating shaft forms an angle of 75°-85° with the top plate of the stirring blade.

At the same time, the curved stirring blade can make the added alkali activator and other liquid additives flow better along the stirring blade. For geopolymer grouting materials, it can effectively promote the alkali activator to be better integrated into the mixed grouting material to ensure the adequacy of the alkali excitation reaction and ensure the performance of the grouting material from the mixing process. This fan blade design can effectively improve the uniformity of the grouting material during the mixing process and make the stirring effect more sufficient.

[0019] The beneficial effects of the embodiments of the utility model are:

At the same time, the curved stirring blades can make the added alkali activator and other liquid additives flow better along the stirring blades. For geopolymer materials, it can effectively promote the alkali activator to be better integrated into the mixed grouting material to ensure the adequacy of the alkali excitation reaction and ensure the performance of the grouting material from the mixing process.
