[0033] Reference Figure 3 The outer wall of the tank body 1 is fixedly connected with a driving motor 41, and the driving motor 41 is used to provide power. The output shaft of the driving motor 41 is fixedly connected with a driving gear 42, and the outer wall of the hollow main shaft 43 is fixedly connected with a driven gear 44. The output shaft of the driving motor 41 drives the driving gear 42 to rotate, and the driving gear 42 drives the driven gear 44 to rotate, and the driven gear 44 drives the hollow main shaft 43 to rotate, which plays a transmission role. The bottom of the hollow main shaft 43 is rotatably connected with an air intake pipe 45, and the right side of the air intake pipe 45 is used to connect an air compressor to provide high-pressure air for the hollow main shaft 43. The outer wall of the air intake pipe 45 is fixedly connected with a connecting support frame 46, and the connecting support frame 46 provides fixed support for the air intake pipe 45.

[0034] Reference Figure 5A rotation mechanism 5 is provided on the inner wall of the tank body 1, and the rotation mechanism 5 includes a rotating gear 51. A fixed block 52 is fixedly connected to the top of the rotating gear 51. The rotating gear 51 drives the fixed block 52 to rotate. A spring piece 53 is fixedly connected to the outer wall of the fixed block 52. An inner gear ring 54 is fixedly connected to the inner wall of the tank body 1. A fixed column 55 is fixedly connected to the top of the inner gear ring 54. When the spring piece 53 rotates to conflict with the fixed column 55, the spring piece 53 first knocks the fixed column 55, and then the spring piece 53 is deformed.

[0035] Reference Figure 2-Figure 4 The top of the connecting support frame 46 is fixed to the bottom of the tank body 1, which plays a role of fixed support. The bottom of the tank body 1 is fixedly connected with a discharge port 3, which is used to open the valve to discharge the material after cleaning. The oblique slots 49 are arranged in an array, which is convenient for outputting high-pressure air to materials at different heights in the tank body 1. The outer wall of the hollow main shaft 43 is fixedly connected to the inner wall of the driven gear 44, and the driven gear 44 drives the hollow main shaft 43 to rotate, which plays a transmission role. The hollow main shaft 43 is a hollow column type, the hollow connecting piece 47 is a hollow plate type, and the inner wall of the hollow stirring rod 48 is hollow. The hollow stirring rod 48, the oblique slots 49, and the hollow connecting piece 47 are connected to the inner wall of the hollow main shaft 43, which is convenient for the transportation of high-pressure air.

[0036] Reference Figure 3-Figure 5 The top of the hollow stirring rod 48 is fixedly connected to the bottom of the rotating gear 51, and the hollow stirring rod 48 drives the rotating gear 51 to rotate. The inner wall of the inner gear ring 54 meshes with the surface of the rotating gear 51. When the hollow stirring rod 48 drives the rotating gear 51 to rotate, the rotating gear 51 rotates under the action of the inner gear ring 54, so that the hollow stirring rod 48 also rotates. The fixed column 55 is arranged in a circular array at the top of the inner gear ring 54. When the spring piece 53 no longer conflicts with the fixed column 55, it returns to its original position under the action of its own elastic potential energy. The spring piece 53 belongs to the prior art, and the material of the spring piece 53 is not repeated. The outer wall of the driving gear 42 meshes with the outer wall of the driven gear 44, and the driving gear 42 drives the driven gear 44 to rotate, which plays a transmission role.

[0037] Working principle: put the raw materials of phosphogypsum and water into the tank body 1 through the top cover 2, turn on the driving motor 41, the driving motor 41 drives the driving gear 42 to rotate, the driving gear 42 drives the driven gear 44 to rotate, the driven gear 44 drives the hollow main shaft 43 to rotate, the hollow main shaft 43 drives the hollow connecting piece 47 to rotate, the hollow connecting piece 47 drives the hollow stirring rod 48 to rotate, and the hollow stirring rod 48 stirs and washes the material.

[0038] At this time, high-pressure air is introduced into the air inlet pipe 45, and then through the hollow main shaft 43, the hollow connector 47, the hollow stirring rod 48 and the oblique slot 49, the high-pressure air is ejected obliquely downward from the air nozzle 410. The high-pressure air jet can help mix and disperse the water and phosphogypsum together. The oblique downward jet can produce a rotation and vortex effect, so that the phosphogypsum particles are suspended in the water and remain in the liquid to prevent them from settling or accumulating. This helps to ensure uniformity and continuity during the treatment process, and ensures thorough contact and reaction. This helps to achieve a more uniform reaction during the treatment process and improve the cleaning efficiency.

[0039] Furthermore, the downwardly diagonally high-pressure air will flush the inner wall of the tank body 1 , thereby preventing the phosphogypsum-water mixture from adhering to the inner wall of the tank body 1 .

[0040] When the hollow stirring rod 48 rotates around the hollow main shaft 43, the hollow stirring rod 48 drives the rotating gear 51 to rotate, and the rotating gear 51 rotates under the action of the inner ring gear 54, so that the hollow stirring rod 48 rotates around the hollow main shaft 43 and rotates at the same time, so that the high-pressure air sprayed from the air nozzle 410 on the hollow stirring rod 48 is more uniform, which improves the high-pressure air spraying effect, makes the mixing of high-pressure air and materials more uniform, and further improves the cleaning effect.

[0041] At the same time, it is convenient to throw the adhered material on the surface of the hollow stirring rod 48 out through centrifugal force, and at the same time, the rotating gear 51 drives the fixed block 52 and the spring 53 to rotate, and the spring 53 repeatedly knocks the fixed column 55 to generate vibration. The force generated by the knocking can destroy the bonding force between the adhered material and the surface through mechanical action. When the object is knocked, the force generated can cut off or weaken the adhesion between the adhered material and the surface, making it easy to remove, making it more difficult for the material to adhere to the inner wall of the tank body 1.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
