[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, a high-efficiency polycarboxylate water-reducing agent reactor comprises a bracket 1, a kettle body 2 is connected to the bracket 1, a feed port 3 and an exhaust hole are arranged at the top of the kettle body 2, a discharge port 16 is arranged at the bottom, a stirring motor 4 is centrally connected to the top of the kettle body 2, a power output end of the stirring motor 4 is arranged inside the kettle body 2, and a stirring mechanism is connected, the stirring mechanism comprises a first stirring shaft 14, and first stirring blades 13 are evenly spaced and distributed on the first stirring shaft 14;

[0020] A toothed disc 6 sleeved with a first stirring shaft 14 is provided in the kettle body 2, and the top of the toothed disc 6 is connected to the top of the kettle body 2 through a support 5. A driving disc 10 is fixedly connected to the first stirring shaft 14, and a plurality of supporting plates 9 are extended to the driving disc 10 in all directions. The end of the supporting plate 9 away from the first stirring shaft 14 is rotatably connected to a second stirring shaft 12, and the second stirring shaft 12 is connected to second stirring blades 11 evenly spaced.

[0021] A transmission gear 7 is rotatably connected above the support plate 9 , and the transmission gear 7 meshes with the toothed disc 6 . The top end of the second stirring shaft 12 is located above the support plate 9 , and is connected to a driven gear 8 , and the driven gear 8 meshes with the transmission gear 7 .

[0022] When the first stirring shaft 14 rotates, it will drive the driving disk 10 and the supporting plate 9 to rotate, so that the transmission gear 7 rotates around the toothed disk 6, and the toothed disk 6 engages with the transmission gear 7 to rotate the transmission gear 7, and the driven gear 8 engages with the transmission gear 7 to rotate, thereby realizing the driving of the second stirring shaft 12, and the first stirring shaft 14 and the second stirring shaft 12 rotate in opposite directions, so as to achieve a better stirring effect.

[0023] In order to avoid interference between the first stirring blade 13 and the second stirring blade 11 , the first stirring blade 13 and the second stirring blade 11 are staggered, and a stronger stirring effect can be formed by staggering.

[0024] Since the driving disk 10 and other components are connected to the first stirring shaft 14, in order to improve the stability of the first stirring shaft 14, the bottom end of the first stirring shaft 14 is further rotatably connected to a support platform 15, and the bottom of the support platform 15 is connected to the bottom end of the kettle body 2 through a column 17, which can provide a fixing effect for the end of the first stirring shaft 14 to avoid shaking during rotation.

A valve or an external guide pipe can be added to the discharge port 16 to facilitate the outward guidance of the discharge.

[0026] When the kettle body 2 is filled with raw materials, the overall weight is relatively large. In order to ensure the stability of the frame support, the bracket 1 further includes an annular frame 1.1, and a plurality of supporting legs 1.2 are provided at the bottom of the annular frame 1.1.
