In this embodiment, the support base 1 includes a horizontally placed top plate and four support legs fixed at the four corners of the bottom of the top plate. The mixing tank 2 is a cylindrical sealed cavity placed vertically at the top of the top plate, which can avoid fly ash pollution of the environment and damage to the health of workers during the mixing process.

[0018] The stirring mechanism 5 includes a stirring shaft 501 rotatably mounted inside the stirring tank 2, several stirring blades 502 mounted on the stirring shaft 501, and a rotary drive 503 that drives the stirring shaft 501 to rotate. The stirring shaft 14 is rotatably mounted in the middle inside the stirring tank 2 via bearings. The rotary drive 503 is specifically a motor, which is mounted at the top of the stirring tank 2. The top of the stirring shaft 14 extends to the outside of the stirring tank 2 and is connected to the motor via a coupling. The stirring shaft 14 and the stirring tank 7 are filled with sealing material to prevent fly ash. During operation, the motor drives the stirring shaft 501 and the stirring blades 502 to rotate, thereby stirring and mixing the raw materials inside the stirring tank 2.

[0019] In this embodiment, the mixing tank 2 is equipped with a distribution plate 7 that rotates synchronously with the mixing mechanism 5. The side wall of the distribution plate 7 is provided with a plurality of liquid outlet holes 701. Specifically, the distribution plate 7 is a cylindrical cavity with an open top. The distribution plate 7 is coaxially fixed to the top of the mixing shaft 501. The mixing shaft 501 can drive the distribution plate 7 to rotate synchronously. The top of the inner side wall of the mixing tank 2 is provided with an annular limiting seat 201 that fits tightly against the outer side wall of the top of the distribution plate 7 to improve the stability of the rotation of the distribution plate 7. Furthermore, in order to improve the sealing performance, a sealing ring can be provided on the contact surface between the annular limiting seat 201 and the distribution plate 7. In order to avoid the blockage of the liquid outlet holes 701, a scraper (not shown in the figure) that fits tightly against the side wall of the distribution plate 7 can also be provided on the annular limiting seat 201 to scrape off the cement adhering to the outer side wall of the distribution plate 7, thereby playing a cleaning role.

[0020] A feeding tank 3 is provided at the top of the mixing tank 2, and the feeding tank 3 includes a first storage chamber 301 for storing powder materials and a plurality of second storage chambers 302. A sealing cover 4 corresponding to the first storage chamber 301 and the second storage chamber 302 is provided at the top of the feeding tank 3, and a handle 401 is provided on the sealing cover 4. The bottom end of the first storage chamber 301 is provided with a first feeding funnel 3011 extending into the interior of the mixing tank 2, and the bottom end of the second storage chamber 302 is provided with a second feeding funnel 3021 extending into the interior of the distribution plate 7. The distribution plate 7 can evenly throw the liquid raw materials entering the chamber out to the surroundings, making the mixing more uniform and efficient. Both the first feeding funnel 3011 and the second feeding funnel 3021 are provided with solenoid valves 303 to control the feeding speed. In this embodiment, the number of second storage chambers 302 is set to three, which are used to store NaOH, water glass and water respectively. Other numbers can also be set as needed. The distance between the three second feeding funnels 3021 and the stirring shaft 501 is smaller than the distance between the first feeding funnel 3011 and the stirring shaft 501 to avoid affecting the rotation of the distribution plate 7. The specific dimensions of the first storage chamber 301 and the second storage chamber 302 can be set according to the required amount of raw materials.

[0021] The bottom of the mixing tank 2 is provided with a discharge port 6 extending to the bottom of the support base 1. A valve is installed on the discharge port 6, and the discharge port 6 is specifically located on one side of the bottom of the mixing tank 2. After mixing is completed, cement can be automatically discharged downwards, and washing water can also be conveniently discharged downwards. There is no need for manual digging, and the degree of automation is high.

[0022] Working principle: First, powder material is added into the first storage chamber 301. NaOH, water glass, and water are added into the three second storage chambers 302 respectively. During operation, the powder material, NaOH, water glass, and water can be added into the mixing tank 2 through the solenoid valve 303. The rotating drive component 503 drives the stirring shaft 501 to rotate. The stirring shaft 501 drives the stirring blades 502 and the distribution plate 7 to rotate. The raw materials such as NaOH, water glass, and water first enter the interior of the distribution plate 7, and then are evenly sprinkled around under the action of centrifugal force. The stirring blades 502 mix and stir the raw materials inside. The cement that has been mixed is discharged downward through the discharge port 6.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
