[0031] Specifically, a stirring machine power assembly 3 is installed on one side of the stirring cylinder 21, a stirring rod 4 is connected to an output end of the stirring machine power assembly 3, a pre-stirring bin assembly 6 is installed above the support frame 1, a fly ash inlet pipe 51 is installed on the top of the pre-stirring bin assembly 6, when the fly ash enters the pre-stirring bin assembly 6 from the fly ash inlet pipe 51 installed through the cover plate 62, a solidifying agent inlet pipe 52 is installed on the top of the pre-stirring bin assembly 6, the solidifying agent is added at the solidifying agent inlet pipe 52, the solidifying agent falls on the conveying belt 83, a stirring liquid pipe assembly 7 is installed inside the pre-stirring bin assembly 6, the chelating agent or water starts to be sprayed outward through the pipeline 71 at the liquid outlet 72, the chelating agent is sprayed into the falling fly ash and solidifying agent, a conveying assembly 8 is installed inside the pre-stirring bin assembly 6, and the conveying belt 83 is also inclined, the fly ash can roll forward by itself, the conveying speed is faster, and the fly ash can be added in a large amount without affecting the fly ash.

[0032] Please refer to Figure 2 and Figure 3 A discharge port 22 is formed in the bottom of the stirring cylinder 21, the stirring rod 4 is installed obliquely inside the stirring cylinder 21, the inner wall of the stirring cylinder 21 and the stirring rod 4 are parallel, the stirring rod 4 and the inner wall of the stirring cylinder 21 are inclined to the ground, and the discharge port 22 at the lowest point of the bottom can conveniently discharge the fly ash stirring material outward.

[0033] Please refer to Figure 1 and Figure 3 The pre-stirring bin assembly 6 comprises a pre-stirring bin 61 installed above the support frame 1, the top of the pre-stirring bin 61 is provided with a cover plate 62, and a fixed block 63 is fixed on one side of the pre-stirring bin 61. The three materials can be mixed above the stirring cylinder 21, the stirring rod 4 can be stirred more uniformly, and the fixed block 63 can be installed with a motor 81.

[0034] Please refer to Figure 4 and Figure 5 The stirring liquid pipe assembly 7 comprises a pipeline 71 installed inside the pre-stirring bin 61, and a plurality of liquid outlets 72 are formed on one side of the pipeline 71. The plurality of liquid outlets 72 can spray the stirring liquid more evenly on the mixture.

[0035] Please refer to Figure 3 - Figure 5 The conveying assembly 8 comprises a motor 81 installed above the fixed block 63, and the output end of the motor 81 is connected with a square rod 82, one end of the square rod 82 is provided with a roller shaft 85, the outer wall of the roller shaft 85 is sleeved with a conveying belt 83, and the two ends of the roller shaft 85 are provided with fixed rods 84. When the fly ash and the curing agent enter the pre-mixing bin 61 from the fly ash inlet pipe 51 and the curing agent inlet pipe 52, they can fall on the conveying belt 83, and the first fusion of the two can be realized, which facilitates subsequent uniform stirring.

[0036] Please refer to Figure 3 The conveying belt 83 is installed in an inclined state in the pre-mixing bin 61, and the inclined direction of the conveying belt 83 is opposite to the inclined direction of the stirring rod 4. The conveying belt 83 conveys the fly ash and curing agent mixture to the high place of the stirring rod 4, and along with the slope, the mixture moves downward, so that the stirring is more uniform.

[0037] Please refer to Figure 4 and Figure 5 The liquid outlet 72 is in a horn shape, so that the stirring liquid can be sprayed outward in a jet shape, the contact area of the stirring liquid with the mixture is larger, the mixing is more uniform, and the stirring time is reduced.

[0038] The working principle of the utility model is as follows: when the fly ash enters the pre-mixing bin 61 from the fly ash inlet pipe 51 installed through the cover plate 62, the motor 81 installed above the fixed block 63 is started at this time, the output end of the motor 81 drives the square rod 82 to rotate, so that the roller shaft 85 rotates, and the conveying belt 83 starts to convey. The fly ash falls on the conveying belt 83 and moves forward along with the conveying belt 83. Since the plurality of fixed rods 84 are installed in an inclined manner, the conveying belt 83 is also inclined, and the fly ash can roll forward by itself, so that the conveying speed is faster, and the addition of a large amount of fly ash will not be affected.

[0039] At this time, the curing agent is added at the curing agent inlet pipe 52, and the curing agent falls on the conveying belt 83. Since the conveying belt 83 already has fly ash, the first fusion of the two is started. Along with the conveying of the conveying belt 83, the fly ash and the curing agent start to fall freely at the end of the conveying belt 83. At this time, the chelating agent or water starts to be sprayed outward at the liquid outlet 72 through the pipeline 71. The chelating agent is sprayed into the falling fly ash and curing agent, and the three are mixed in the air before reaching the stirring cylinder 21. Since the positions where the three fall on the stirring cylinder 21 are consistent, when the stirring rod 4 starts to work, the stirring is more uniform and simple.

[0040] Due to the inclination angle of the inner wall of the stirring cylinder 21, the mixture of fly ash, solidifying agent and chelating agent will move to the discharge port 22 under the stirring of the stirring rod 4 along with the inclination angle of the inner wall of the stirring cylinder 21, and finally the mixture is guided out of the discharge port 22 after the stirring is completed, and the next process flow is carried out.

[0041] Although the embodiments of the present application have been shown and described, the specific embodiments are merely illustrative of the present application, and are not intended to limit the present application, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification without departing from the principles and purposes of the present application, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
