[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the anti-precipitation polycarboxylate water-reducing agent reactor comprises a reactor body 9 and a reactor cover 1 connected to the top of the reactor body 9. A discharge port 13 and support legs 12 are arranged at the bottom of the reactor body 9. The discharge port 13 is centrally arranged and connected to a valve 14. The support legs 12 are evenly spaced around the discharge port 13. A feed port 2 and an axial hole 8 are arranged on the reactor cover 1. The axial hole 8 is centrally arranged. A motor 3 is connected to the top of the reactor cover 1. The motor 3 is connected to a stirring shaft 6 through a driving mechanism. The stirring shaft 6 is installed in the shaft hole 8 through a bearing 7.

[0022] The stirring shaft 6 is located in the kettle body 9 and is connected to a stirring mechanism 10, and the end thereof is connected to a stirring and anti-sedimentation mechanism 11;

[0023] The stirring and anti-sedimentation mechanism 11 comprises a mounting seat 11.2 fixed to the end of the stirring shaft 6, and swing arms 11.3 are connected to both ends of the mounting seat 11.2, and stirring blades 11.4 are connected to the end of the swing arm 11.3.

[0024] The stirring mechanism 10 cooperates with the stirring anti-sedimentation mechanism 11 to effectively prevent the material in the kettle body 9 from being precipitated.

[0025] In order to expand the stirring coverage of the stirring blade 11.4 and improve the stirring and anti-sedimentation effect of the stirring blade 11.4, further, the swing arm 11.3 is rotatably connected to the mounting seat 11.2 through the pin 11.1, and a torsion spring (not shown in the figure) is sleeved on the pin 11.1, one end of the torsion spring is connected to the swing arm 11.3, and the other end is connected to the mounting seat 11.2. With the driving action of the motor 3, the stirring shaft 6 drives the stirring and anti-sedimentation mechanism 11 to rotate. When the rotation speed of the motor 3 changes, the centrifugal force of the stirring blade 11.4 driven by the swing arm 11.3 will also change. When the motor 3 rotates at a fast speed, the swing arm 11.3 drives the stirring blade 11.4 to expand outwards, and when the rotation speed is slow, the swing arm 11.3 shrinks inwards under the action of the torsion spring.

[0026] Furthermore, the stirring mechanism 10 includes a support rod 10.1 connected to the upper and lower parts of the stirring shaft 6, and the ends of the support rods 10.1 on the same side are commonly connected with a scraper 10.3, and the scraper 10.3 fits the inner wall of the kettle body 9, and cooperates with the stirring anti-sedimentation mechanism 11, so that the inner wall of the kettle body 9 can be cleaned in time while stirring.

[0027] In order to ensure the stirring effect, further, S-shaped blades 10.2 are connected between the support rods 10.1 on the same side.

[0028] Furthermore, the stirring blades 11.4 are provided with evenly distributed through holes 11.5. The two stirring blades 11.4 are initially distributed in an eight-shaped shape. Setting an initial angle for the stirring blades 11.4 is conducive to subsequent unfolding during rotation and avoids the stirring blades 11.4 from hitting the scraper 10.3 when unfolding.

[0029] Furthermore, the driving mechanism includes a driving gear 4 and a driven gear 5 that mesh with each other. The driving gear 4 is fixed to the power output end of the motor 3 , and the driven gear 5 is fixed to the top of the stirring shaft 6 .

[0030] When the utility model is actually used, the material is fed into the kettle through the feed port 2, and then the motor 3 is started for sufficient stirring. The motor 3 adopts a variable speed motor 3, and the swing amplitude of the swing arm 11.3 can be controlled by controlling the rotation speed of the motor 3 to make it change regularly, thereby expanding the stirring coverage of the bottom of the kettle body 9, so that the material at the bottom of the kettle body 9 is fully stirred to avoid precipitation. At the same time, the scraper 10.3 of the stirring mechanism 10 can clean the inner wall of the kettle body 9 in real time. After the stirring reaction of the material is completed and discharged through the discharge port 13, it is convenient to clean the inside of the kettle body 9.
