[0030] In this embodiment, the liquid concrete air-entraining agent raw material added according to the concrete slump at the preparation position is added into the preparation tank body 6, and then the motor 13 and the main body are controlled to work. At this time, the liquid concrete air-entraining agent raw material in the preparation tank body 6 will be stirred in two directions, which can speed up the mixing efficiency of the liquid concrete air-entraining agent raw material, thereby avoiding the problem that most of the existing mixing equipment for preparing the liquid concrete air-entraining agent used to improve the concrete slump only has a one-way stirring function, which is not convenient for improving the preparation efficiency of the liquid concrete air-entraining agent.

[0031] As a technical optimization solution of the present utility model, the inner wall of the preparation tank body 6 is fixedly connected with mixing blades 5, and the number of the mixing blades 5 is several.

[0032] In this embodiment, by controlling the rotation of the preparation tank body 6, the mixing blades 5 on the inner wall of the preparation tank body 6 can be rotated, so that the liquid concrete air entraining agent raw materials inside the preparation tank body 6 can be mixed, achieving the effect of facilitating the mixing of the liquid concrete air entraining agent raw materials.

[0037] As a technical optimization solution of the present invention, a handle 11 is fixedly connected to the surface of the prepared tank body 6 , and the number of the handles 11 is several and evenly distributed on the surface of the prepared tank body 6 .

[0038] In this embodiment: when the motor 13 stops rotating, the preparation tank body 6 can be driven to rotate again by pulling the handle 11, so as to facilitate the alignment of the discharge pipe 7 with the notch 8, thereby achieving the effect of facilitating the rotation of the preparation tank body 6.

[0039] As a technical optimization solution of the utility model, the front side of the preparation tank body 6 is fixedly connected with a discharge pipe 7, the front side of the discharge pipe 7 is provided with a sealing cover 15, and the surface of the sealing cover 15 is connected to the internal thread of the discharge pipe 7.

[0040] In this embodiment, after the preparation of the concrete air-entraining agent is completed, the sealing cover 15 is rotated.

When the sealing cover 15 is rotated, the sealing cover 15 can be separated from the discharge pipe 7, and the prepared liquid concrete air-entraining agent can be discharged from the preparation tank body 6, thereby achieving the effect of conveniently discharging the prepared liquid concrete air-entraining agent from the preparation tank body 6.

[0041] As a technical optimization solution of the present invention, a notch 8 is provided inside the bottom plate 1 , and the notch 8 is located at the bottom of the discharge pipe 7 .

[0042] In this embodiment, after the discharge pipe 7 is opened, the external container is moved to the bottom of the notch 8, so that the prepared liquid concrete air-entraining agent discharged from the discharge pipe 7 can enter the external container, thereby achieving the effect of conveniently using the external container to receive the prepared liquid concrete air-entraining agent.

[0043] As a technical optimization solution of the present invention, handles 2 are fixedly connected to both sides of the base plate 1 .

[0044] In this embodiment, by holding the handle 2 and moving the handle 2 , the bottom plate 1 and the preparation tank 6 can be moved, thereby achieving the effect of facilitating the movement of the bottom plate 1 .

[0045] As a technical optimization solution of the present invention, the bottom of the base plate 1 is fixedly connected with supporting legs 9 , and the number of the supporting legs 9 is four and they are evenly distributed at the four corners of the bottom of the base plate 1 .

[0046] In this embodiment: by moving the bottom plate 1 and the preparation tank body 6 to a stable position, the legs 9 at the bottom of the bottom plate 1 will provide stable support for the bottom plate 1, thereby achieving the effect of facilitating stable support for the bottom plate 1.

[0049] Working principle: First, hold the handle 2 and move the handle 2 to move the bottom plate 1 and the preparation tank body 6 to a stable position. At this time, the support legs 9 at the bottom of the bottom plate 1 will stably support the bottom plate 1. Then, the liquid concrete air-entraining agent raw material added according to the concrete slump at the preparation position is added into the preparation tank body 6. Then, the motor 13 is controlled to rotate. The rotation of the motor 13 can drive the preparation tank body 6 and the mixing blades 5 on the inner wall of the preparation tank body 6 to rotate through the output shaft. The preparation tank body 6 rotates inside the annular groove 12 through the ball bearing 14. The support pillar 10 and the ball bearing 14 can support the preparation tank body 6 for rotation, so that the rotation of the preparation tank body 6 is more stable. Then, the pump body 401 is controlled to work. When the pump body 401 works, the liquid concrete air-entraining agent raw material inside the preparation tank body 6 can be fed into the liquid inlet pipe 404. The liquid concrete air-entraining agent raw material is sucked in and then discharged into the drain pipe 402, and then the liquid concrete air-entraining agent raw material is sprayed out through the bend pipe 403 connected to the surface of the drain pipe 402 in the opposite direction, so that the liquid concrete air-entraining agent raw material rotates inside the preparation tank body 6. It should be noted that the rotation direction of the preparation tank body 6 driven by the output shaft of the motor 13 is opposite to the rotation direction of the liquid concrete air-entraining agent raw material discharged by the bend pipe 403. At this time, the liquid concrete air-entraining agent raw material can be stirred in two directions, and the liquid concrete air-entraining agent raw material inside the preparation tank body 6 can be quickly mixed, avoiding the problem that most of the existing mixing equipment for preparing the liquid concrete air-entraining agent used to improve the slump of concrete only has a one-way stirring function, which is not convenient for improving the preparation efficiency of the liquid concrete air-entraining agent.
