[0004] Although the above-mentioned prior art solution can drive the first stirring blade to rotate by the first motor and the second stirring blade to rotate by the second motor, this method will result in different stirring directions, causing the stirring device to bear greater stress and fatigue damage, making the stirring shaft, stirring blades and other components prone to wear, deformation and even breakage under different stirring directions. Therefore, it is urgent to design a polycarboxylate water-reducing agent storage and homogenization device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: a polycarboxylate water reducer storage homogenization device, comprising: a tank body 1, a connection cover 2 is movably connected to the top of the tank body 1, a protection box 3 is fixedly connected to the top of the connection cover 2, a positioning ring 4 is fixedly connected to the outer surface of the protection box 3, a driving motor 5 is fixedly connected to the inside of the positioning ring 4, an output end of the driving motor 5 is fixedly connected to a first rotating gear 6, a second rotating gear 7 is meshed with the side surface of the first rotating gear 6, a rotating shaft 8 is fixedly connected to the center of the second rotating gear 7, a gear ring 9 is meshed with the outer surface of the second rotating gear 7, a first connecting rod 10 is fixedly connected to the outer surface of the rotating shaft 8, a first connection buckle 17 is fixedly connected to the outer surface of the first connecting rod 10, a second connection buckle 18 is movably connected to the outer surface of the first connection buckle 17, a fixing bolt 19 is movably connected to the inside of the first connection buckle 17, a second connecting rod 20 is fixedly connected to the outer surface of the second connection buckle 18, and a stirring rod 21 is fixedly connected to one end of the second connecting rod 20 away from the second connection buckle 18.

[0024] Specifically, through the setting of the positioning ring 4, it can effectively play a role in supporting the driving motor 5, and a rotating part 11 and a first rotating gear 6 are fixedly connected to the outer surface of the output end of the driving motor 5.

[0025] Please refer to Figures 1-4 , a rotating part 11 is fixedly connected to the output end of the driving motor 5, and a connecting plate 12 is fixedly connected to the outer surface of the rotating part 11.

[0026] Specifically, through the setting of the connecting plate 12, it can effectively play a role in connecting the rotating part 11 and the rotating frame 13, so that the rotating frame 13 can be driven to rotate synchronously while the rotating part 11 rotates.

[0027] Please refer to Figures 1-4 , a rotating frame 13 is fixedly connected to one end of the connecting plate 12 away from the rotating part 11, and a movable groove 14 is formed in the inside of the rotating frame 13.

[0028] Specifically, through the setting of the movable groove 14, the first connecting rod 10 can pass through the rotating frame 13, so that the first connecting rod 10 can pass from the inner top end of the tank body 1 to the inner bottom end of the tank body 1.

[0029] Please refer to Figures 1-4 , a scraping plate 15 is fixedly connected to the bottom of the rotating frame 13, and a bottom frame 16 is fixedly connected to the bottom of the scraping plate 15.

[0030] Specifically, through the setting of the scraping plate 15, the outer surface of the scraping plate 15 is inclined. When the polycarboxylate water reducer precipitates, under the action of the scraping plate 15, the polycarboxylate water reducer adhered to the inner wall of the tank body 1 can be scraped off to avoid accumulation and difficult cleaning.

[0031] Please refer toFigures 1-4 The scraping plate 15 is fixedly connected between the rotating frame 13 and the base frame 16, and the center of the base frame 16 is hollow.

[0032] Specifically, through the setting of the base frame 16, the base frame 16 and the rotating frame 13 rotate synchronously under the action of the scraping plate 15, and the base frame 16 can effectively guarantee the integrity of the scraping plate 15 and prevent the scraping plate 15 from breaking due to excessive force.

[0033] Please refer to Figures 1-4 , one side of the tooth ring 9 away from the second rotating tooth 7 is fixedly connected to the inner wall of the protective box 3, and the second rotating teeth 7 are evenly meshed in three groups on the inner side of the tooth ring 9.

[0034] Specifically, through the setting of the tooth ring 9, when the first rotating tooth 6 rotates, the first rotating tooth 6 will drive the second rotating tooth 7 to rotate inside the tooth ring 9, thereby driving the stirring rod 21 to rotate.

[0035] Please refer to Figures 1-4 , the fixing bolt 19 penetrates and connects the side surfaces of the first connecting buckle 17 and the second connecting buckle 18, and the first connecting buckle 17 and the second connecting buckle 18 are movably connected between the first connecting rod 10 and the second connecting rod 20.

[0036] Specifically, through the setting of the first connecting buckle 17 and the second connecting buckle 18, the free disassembly of the stirring rod 21 can be realized, so as to facilitate the later maintenance or replacement of the stirring rod 21, thereby improving the practicability of the device.

[0037] Please refer to Figures 1-4 , the stirring rod 21 is fixedly connected to the bottom of the second connecting rod 20, and the stirring rod 21 is rotatably connected inside the stirring rod 21.

[0038] Specifically, through the setting of the stirring rod 21, when the stirring rod 21 rotates, the polycarboxylate superplasticizer will be turned over and stirred to prevent the polycarboxylate superplasticizer from precipitating and accumulating at the bottom.

[0039] Working principle: When in use, the stirring rod 21 is fixedly connected to the first connecting buckle 17 through the second connecting buckle 18, and the driving motor 5 is started, so that the driving motor 5 drives the first rotating gear 6 to rotate. Since the second rotating gear 7 is meshed between the first rotating gear 6 and the gear ring 9, the second rotating gear 7 will rotate along the inner side of the gear ring 9 under the drive of the first rotating gear 6. The rotating shaft 8 is fixedly connected inside the second rotating gear 7. While the rotating shaft 8 drives the stirring rod 21 to rotate with the first rotating gear 6 as the axis, the stirring rod 21 will also rotate itself. When the stirring rod 21 rotates, it will rotate and turn up the polycarboxylate water reducer inside the tank body 1, turning the bottom layer of the polycarboxylate water reducer to the top layer to prevent the polycarboxylate water reducer from precipitating or stratifying inside the tank body 1; the rotating part 11 is fixedly connected to the bottom of the output end of the driving motor 5. When the rotating part 11 rotates with the driving motor 5, the rotating part 11 will drive the rotating frame 13, the scraping plate 15, and the bottom frame 16 to rotate synchronously through the connecting plate 12. Since one side of the scraping plate 15 facing the rotation direction is inclined, the scraping plate 15 will scrape off the polycarboxylate water reducer on the inner wall of the tank body 1 while rotating, so that the mixing is more sufficient.

[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
