[0027] The present invention will be further described below with reference to the embodiments.

[0028] See also Figure 1-6The utility model provides a stirring device for producing a water reducing agent, comprising a mixing tank 1, the bottom of the mixing tank 1 being a hemispherical structure, a discharge pipe 11 being fixedly embedded on one side of the bottom of the mixing tank 1, and a valve 12 being installed on the discharge pipe 11;

[0029] Specifically, the hemispherical bottom structure of the mixing tank 1 is conducive to the flow and emptying of the water reducer raw material. A valve 12 is installed on the discharge pipe 11. The function of this valve 12 is to control the switch of the discharge pipe 11, thereby controlling the discharge of the water reducer raw material. When the water reducer needs to be discharged, the valve 12 can be opened to allow the water reducer to flow out through the discharge pipe 11. When it is not necessary to discharge, the valve 12 can be closed to prevent the raw material from flowing out.

[0030] Furthermore, a bracket 2 is installed below the mixing tank 1. The bracket 2 includes a base 21 located below the mixing tank 1. Four pillars 22 are fixedly connected between the mixing tank 1 and the base 21. Two brackets 23 are fixedly connected to the upper side of the base 21.

[0031] Specifically, the base 21 provides a stable platform to ensure the stability and balance of the mixing tank 1 during the mixing process. Through the reasonable layout of the pillars 22 and the brackets 23, the stable support of the mixing tank 1 and the effective connection of the drive component 3 can be achieved, thereby ensuring the smooth progress of the mixing process.

[0032] Furthermore, a driving assembly 3 is mounted on the bracket 2, and the driving assembly 3 includes a double-headed motor 31 fixed to the middle of the upper side of the base 21, and both output ends of the double-headed motor 31 are fixedly connected to a driving pulley 32 through the adjacent bracket 23, and a driven pulley 33 is provided above the driving pulley 32. The two driven pulleys 33 are respectively fixed to the two ends of the hollow main shaft 4, and a transmission belt 34 is connected between the driving pulley 32 and the driven pulley 33.

[0033] Specifically, the double-headed motor 31 drives the active pulley 32 to rotate, the active pulley 32 drives the driven pulley 33 to rotate through the transmission belt 34, the driven pulley 33 drives the hollow main shaft 4 to rotate, and the hollow main shaft 4 drives the first stirring blade 41 to flip up and down in the mixing tank 1, which can stir the water reducer raw material at the bottom of the mixing tank 1 to flip up, so as to prevent the water reducer raw material from settling.

[0034] Furthermore, a hollow main shaft 4 is rotatably embedded between the two side walls of the mixing tank 1, and a plurality of first stirring blades 41 are distributed on both sides of the hollow main shaft 4. The first stirring blades 41 on the outer wall of the hollow main shaft 4 are of different lengths, and the first stirring blades 41 gradually become shorter from the middle to the two ends of the hollow main shaft 4;

[0035] Specifically, the longer first stirring blade 41 can penetrate into the center area of ​​the mixing tank 1, while the shorter first stirring blade 41 can better act on the area close to the inner wall of the mixing tank 1, thereby ensuring that the raw materials in the entire mixing tank 1 can be fully stirred.

[0036] Furthermore, a solid secondary shaft 5 is rotatably embedded in the middle of the other two sides of the hollow main shaft 4. A plurality of second stirring blades 51 are distributed on both sides of the solid secondary shaft 5. The second stirring blades 51 on the outer wall of the solid secondary shaft 5 are of different lengths, and the second stirring blades 51 gradually become shorter from the hollow main shaft 4 outwards.

[0037] Specifically, the second stirring blades 51 of different lengths can cover different areas in the mixing tank 1 , which helps to achieve a more comprehensive stirring effect and ensure that the water reducer raw materials are evenly mixed in the entire mixing tank 1 .

[0038] Furthermore, the driving assembly 3 is transmission-connected to the hollow main shaft 4, and a driven assembly 6 is transmission-connected between the hollow main shaft 4 and the solid secondary shaft 5. The driven assembly 6 includes a central shaft 61 located in the hollow main shaft 4, and both ends of the central shaft 61 pass through the hollow main shaft 4 and are fixedly connected to a connecting frame 62. The two connecting frames 62 are fixedly connected to the mixing tank 1. A fixed bevel gear 63 is fixedly sleeved on the outer side of the middle part of the central shaft 61. A movable bevel gear 64 is provided on both sides of the fixed bevel gear 63. The two movable bevel gears 64 are meshed and connected with the fixed bevel gear 63, and the movable bevel gears 64 are fixedly connected to the adjacent solid secondary shaft 5.

[0039] Specifically, when the hollow main shaft 4 rotates, it can drive the solid secondary shaft 5 to rotate around the fixed bevel gear 63, and the movable bevel gear 64 rolls along the fixed bevel gear 63, which can drive the solid secondary shaft 5 to rotate. The solid secondary shaft 5 flips left and right in the mixing tank 1, and can stir the water reducer raw materials around the second stirring blade 51, so that the water reducer raw materials can be completely mixed.

[0040] Working principle: When in use, all the water-reducing agent raw materials are added into the mixing tank 1, the double-headed motor 31 drives the driving pulley 32 to rotate, the driving pulley 32 drives the driven pulley 33 to rotate through the transmission belt 34, the driven pulley 33 drives the hollow main shaft 4 to rotate, the hollow main shaft 4 drives the first stirring blade 41 to turn up and down in the mixing tank 1, which can stir the water-reducing agent raw materials at the bottom of the mixing tank 1 to turn over, so as to prevent the water-reducing agent raw materials from settling. At the same time, the hollow main shaft 4 drives the solid secondary shaft 5 to rotate around the fixed bevel gear 63, and the movable bevel gear 64 rolls along the fixed bevel gear 63, which can drive The solid secondary shaft 5 rotates and flips left and right in the mixing tank 1, which can stir the water reducer raw materials around the second stirring blade 51, so that the water reducer raw materials can be completely mixed. The synergistic effect of the first stirring blade 41 and the second stirring blade 51 realizes three-dimensional stirring in the mixing tank 1, ensuring that the raw materials are evenly mixed in the entire space. Since the driving equipment does not need to be built into the mixing tank 1, space is saved, the technical difficulty is reduced, and the volume and weight of the equipment are also reduced. The stirring actions in different directions can achieve the mixing of raw materials more quickly, which can reduce the mixing time and improve production efficiency.
