[0003] At present, the water reducing agent reactor adopts a stirring mechanism arranged at the axis of the reactor body. For example, the utility model patent with publication number CN215540236U discloses a concrete water reducing agent production equipment, in which the stirring blade is located in the center of the reactor.

[0004] In the prior art, when the water reducer reactor is stirred, a funnel-shaped vortex is generated at the center of the reactor. The added ingredients flow along the vortex, resulting in a large inertia in the flow direction and cannot be quickly mixed with other materials, thereby increasing the stirring time and reducing the production efficiency of the water reducer.

[0008] Optionally, the first motor is located outside the kettle body, and a rotating shaft of the first motor extends into the kettle body and is drivingly connected to the first wheel.

[0009] Optionally, it also includes a protective cover; the second driving mechanism is located inside the protective cover, and one end of the agitator extends into the protective cover and is drivingly connected to the second driving mechanism.

[0010] Optionally, an annular slide rail is provided at the bottom of the kettle body, and the agitator cooperates with the slide rail.

[0011] Optionally, the agitator includes a shaft and a paddle; the shaft is drivingly connected to the second driving mechanism; and the paddle is arranged on the shaft.

[0027] In some embodiments, the technician can deliver the raw materials for producing the water reducer into the reaction chamber 101 through the feed port 102. When the agitator 20 stirs the raw materials of the water reducer, the ingredients can continue to be added into the reaction chamber 101 through the feed port 102. The first driving mechanism 320 is fixed on the kettle body 10, and the first driving mechanism 320 drives the connecting plate 310 to rotate around the axis of the kettle body 10 through the connecting rod 340. Among them, the connecting rod 340 connected to the first driving mechanism 320 is used to drive the connecting plate 310, and the remaining connecting rods 340 are used to support the connecting plate 310. The second driving mechanism 330 is fixed on the connecting plate 310, and the second driving mechanism 330 drives the agitator 20 to rotate relative to the connecting plate 310, and the rotation axis is the axis of the agitator 20. Since the second driving mechanism 330 rotates in opposite directions to the first driving mechanism 320, the agitator 20 can prevent the material from forming vortices while stirring the material. At this time, the ingredients are fed into the reaction chamber 101 through the feed port 102, and the diffusion rate of the ingredients is faster, thereby improving the production efficiency of the water reducer.

[0028] The kettle body 10 may be in the shape of an elliptical tank and placed vertically, and a support frame (not shown in the figure) may be provided on the outside of the kettle body 10, and the support frame is used to place the kettle body 10 on the ground. The kettle body 10 may be provided with a mounting plate 110, and the mounting plate 110 is parallel to the connecting plate 310, the connecting rod 340 and the connecting plate 310 may be located below the mounting plate 110, and the first driving mechanism 320 may be located above the mounting plate 110.

[0029] The feed opening 102 may be disposed above the kettle body 10 . Furthermore, the feed opening 102 is located below the connecting plate 310 , so that the movement of the connecting plate 310 will not hinder the raw materials or ingredients from entering the reaction chamber 101 .

[0030] Each connecting rod 340 is rotatably connected to the mounting plate 110, and the rotation axes at both ends of the connecting rod 340 are parallel to the axis of the kettle body 10. The number of connecting rods 340 can be multiple and parallel to each other, wherein the points where the multiple connecting rods 340 are rotatably connected to the connecting plate 310 are connected end to end to form a regular polygon, and the center of the regular polygon is located on the axis of the agitator 20. In some embodiments, the number of connecting rods 340 can be 3, 4, 5, etc., and the number of connecting rods 340 can be set as needed.

[0031] refer to Figure 1 The first driving mechanism 320 includes a first motor 3210, a first wheel 3220, a second wheel 3230 and a transmission member 3240; the first motor 3210 is arranged on the kettle body 10 and is transmission-connected to the first wheel 3220; the second wheel 3230 is coaxially connected to one of the connecting rods 340; the first wheel 3220 and the second wheel 3230 are both transmission-connected to the transmission member 3240.

[0032] As an optional implementation, refer to Figure 1 The first wheel 3220 and the second wheel 3230 can both be pulleys, and the transmission member 3240 can be a belt. The transmission member 3240 is sleeved on the outside of the first wheel 3220 and the second wheel 3230.

[0033] As another optional implementation, the first wheel 3220 and the second wheel 3230 may both be sprockets, and the transmission member 3240 may be a chain.

[0034] As an optional implementation, refer to Figure 1 The first motor 3210 is located outside the kettle body 10 , and the rotating shaft of the first motor 3210 extends into the kettle body 10 and is drivingly connected to the first wheel 3220 .

[0035] In this embodiment, a mounting seat 120 can be set at the upper end of the kettle body 10, the first motor 3210 is fixed on the mounting seat 120, one end of the rotating shaft of the first wheel 3220 is rotatably connected to the mounting plate 110, and the other end of the rotating shaft of the first wheel 3220 extends out of the kettle body 10 and is rotatably connected to the mounting seat 120, and the rotating shaft of the first motor 3210 and the rotating shaft of the first wheel 3220 are connected via a coupling 40.

[0036] As another optional implementation, the first motor 3210 may also be located in the reaction chamber 101 (not shown in the figure). For example, the first motor 3210 may be fixed above the mounting plate 110 .

[0037] As an optional implementation, refer to Figure 1 , also includes a protective cover 50; the second driving mechanism 330 is located inside the protective cover 50, and one end of the agitator 20 extends into the protective cover 50 and is transmission-connected to the second driving mechanism 330.

[0038] In this embodiment, the second driving mechanism 330 may include a second motor, and the rotating shaft of the second motor is connected to the agitator 20. The protective cover 50 is mainly used to protect the second motor to prevent the water vapor in the material from damaging the second motor.

[0039] It should be noted that the kettle body 10 may be provided with a mounting hole for placing the conductive wire, and the conductive wire connected to the second motor may extend from the mounting hole and then be connected to an external power source.

[0040] As an optional implementation, refer to Figure 1 The bottom of the kettle body 10 is provided with an annular slide rail 130, and the agitator 20 cooperates with the slide rail 130. When the connecting plate 310 drives the agitator 20 to rotate around the axis of the kettle body 10, the agitator 20 moves along the slide rail 130. At this time, the second driving mechanism 330 drives the agitator 20 to rotate relative to the connecting plate 310, and the lower end of the agitator 20 rotates in the slide rail 130. The lower end of the agitator 20 can be spherical and is used to abut the slide rail 130. The slide rail 130 supports the agitator 20 and the structure connected to the agitator 20, so as to prevent the connecting plate 310 from being separated from the connecting rod 340 due to the gravity of the second driving mechanism 330 and the agitator 20.

[0041] The agitator 20 includes a shaft body 210 and a paddle 220 ; the shaft body 210 is transmission-connected to the second driving mechanism 330 ; and the paddle 220 is disposed on the shaft body 210 .

[0042] As an optional implementation, refer to Figure 1, the number of paddles 220 is multiple and circumferentially arranged on the shaft body 210; the paddles 220 are in the shape of long plates and the long sides are perpendicular to the axis of the shaft body 210. In this embodiment, one end of each paddle 220 is connected to the shaft body 210, and the other end of each paddle 220 is a free end. This paddle 220 structure makes the paddle 220 weaker in strength. Therefore, the structure of multiple paddles 220 is suitable for scenes where the material viscosity is low and the shaft body 210 of the agitator 20 rotates at a high speed.

[0043] As an optional implementation, refer to Figure 3 The blade 220 is in the shape of a spiral blade. In this embodiment, the blade 220 has more connection points with the shaft 210, and the strength of the spiral blade 220 is also greater. Therefore, the blade 220 of this embodiment can be used in scenes where the material has high viscosity and the shaft 210 of the agitator 20 rotates slowly.

[0044] As an optional implementation, refer to Figure 3 The agitator 20 further includes an agitator 230; the agitator 230 is disposed on the shaft 210, and the agitator 230 is in the shape of an arc rod as a whole. In this embodiment, the agitator 230 can be used in combination with the paddle 220 in the shape of a spiral sheet. In the reaction chamber 101, the material will be deposited to the bottom of the kettle body 10 due to gravity, so that the viscosity of the material at the bottom of the reaction chamber 101 is greater than the viscosity of the material at the top. The rod shape of the agitator 230 makes the agitator 230 have a certain strength, so that the agitator 230 can rotate in a relatively viscous fluid environment.

[0045] The stirring body 230 can be arc-shaped, and the shape of the stirring body 230 can be similar to the internal contour of the kettle body 10. The stirring body 230 can be close to the inner wall of the reaction chamber 101 to prevent the material with high viscosity from sticking to the inner wall of the kettle body 10. The inner wall of the kettle body 10 usually has a heating function, and the material sticking to the inner wall of the kettle body 10 may be coked. Therefore, the stirring body 230 can prevent the material from coking.

[0046] A reinforcing rib 240 may be provided between the stirring body 230 and the shaft body 210 to further improve the strength of the stirring body 230 .

[0047] As an optional implementation, refer to Figure 1 The kettle body 10 is provided with a manhole 103 connected to the reaction chamber 101. The manhole 103 can be located on the side of the axis of the kettle body 10, and the technician can enter the reaction chamber 101 through the manhole 103 and perform operations such as maintenance on the structure inside the kettle body 10.

All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
