[0025] A crushing assembly 2 for crushing the perchloric acid raw material is provided on the top of the tank body 1, which is used to crush the perchloric acid raw material more finely to ensure that the raw material exists in a uniform powder form before stirring, thereby improving its mixing efficiency with water.

[0026] The crushing assembly 2 includes a crushing tank 201, a first motor 202, a rotating rod 203, a crushing disc 204, a sleeve 205, a spiral bar 206, a filter screen 207 and a push plate 208. The crushing tank 201 is arranged on the top of the tank body 1, and the lower end of the crushing tank 201 is connected to the tank body 1. A feeding end for adding raw materials is arranged on the outer side of the crushing tank 201.

[0027] The first motor 202 is arranged on the top of the crushing tank 201, the rotating rod 203 is rotatably arranged on the inner wall of the crushing tank 201, the crushing disk 204 is arranged on the inner wall of the crushing tank 201, and the upper end of the crushing disk 204 is arranged at an angle, and the gravity acceleration is used to cause the perchloric acid raw material to quickly slide to the lower end of the crushing disk 204, the sleeve 205 is arranged on the outer wall of the rotating rod 203, the spiral strips 206 are equidistantly arranged on the outer wall of the sleeve 205, the filter screen 207 is arranged on the inner wall of the crushing tank 201, and the surface of the filter screen 207 is fixed to the bottom of the crushing disk 204, the filter screen 207 is rotatably connected to the rotating rod 203 through a bearing, and the push plate 208 is arranged at one end of the rotating rod 203 away from the first motor 202;

[0028] The perchloric acid raw material is driven to be poured into the crushing tank 201 from the feed end, and the first motor 202 is driven to rotate. The output end of the first motor 202 rotates to drive the rotating rod 203 to rotate, and the rotating rod 203 rotates to drive the sleeve 205 to squeeze the raw material and the crushing disk 204 into contact. When the crushed raw material passes through the filter screen 207 and falls into the tank body 1, and the larger particles after being crushed are stuck on the filter screen 207, the spiral strips 206 on the sleeve 205 will bring the larger particle raw material stuck on the filter screen 207 back into the crushing disk 204 for secondary crushing, thereby ensuring that all raw materials achieve the best crushing effect, and the rotation of the rotating rod 203 drives the push plate 208 to rotate, and the rotation of the push plate 208 can push the raw material passing through the filter screen 207 downward so that it falls into the tank body 1 more quickly.

[0029] A stirring assembly 3 for stirring the perchloric acid raw material is arranged in the tank body 1, and is used to evenly stir the crushed perchloric acid raw material and the added materials.

[0030] The stirring assembly 3 includes a second motor 301, a stirring rod 302, a rotating disk 303, a convex piece 304, a ring sleeve 305, a rotating shaft 306, a stirring blade 307, a pushing bar 308, an arc groove 309, a spring 310 and an arc strip 311. The second motor 301 is arranged on the top of the tank body 1, the stirring rod 302 is rotatably arranged on the inner wall of the tank body 1, the rotating disk 303 has a plurality of equidistantly arranged outer walls of the stirring rod 302, the convex piece 304 is arranged on the surface of the rotating disk 303, the ring sleeve 305 has a plurality of equidistantly arranged outer walls of the stirring rod 302, and the rotating shaft 306 is rotatably arranged on the inner wall of the ring sleeve 305. The stirring blade 307 is arranged on the outer wall of the rotating shaft 306, and the stirring blade 307 is provided with inclined holes 4 at equal intervals, which promotes the inclined fall of the perchloric acid mixture during the stirring process, so that the perchloric acid mixture staying on the stirring blade 307 drips down faster, thereby optimizing the stirring effect. The pushing bar 308 is arranged on the outer wall of the rotating shaft 306, the arc groove 309 is arranged on the inner wall of the sleeve, the spring 310 is arranged on the inner wall of the arc groove 309, the arc bar 311 is arranged at one end of the spring 310, and one end of the arc bar 311 is fixed to the pushing bar 308, and the arc bar 311 is slidably connected to the inner wall of the arc groove 309.

[0031] By driving the second motor 301 to rotate, the output end of the second motor 301 rotates to drive the stirring rod 302 to rotate. The stirring rod 302 rotates and drives the rotating disk 303 to rotate at the same time, and the convex part 304 is rotated by the rotation of the rotating disk 303. When the rotating disk 303 rotates and drives the convex part 304 to rotate until it contacts with the pushing strip 308 and pushes the pushing strip 308, the rotating shaft 306 is pushed by the convex part 304 to rotate toward the side of the spring 310. When the rotating shaft 306 rotates, the pushing part on the rotating shaft 306 pushes the arc strip 311 to retract into the arc groove 309 and compresses the spring 310. When the stirring blade 307 rotates, when the protrusion 304 rotates and no longer contacts the pushing bar 308, the spring 310 recovers its deformation and pushes the arc-shaped bar 311 to reset with the pushing bar 308, so that the stirring blade 307 returns to its original position after the rotation, thereby realizing that the stirring rod 302 rotates to drive the stirring blade 307 to rotate slightly during the stirring process, thereby enhancing the mixing effect between the stirring blade 307 and the perchloric acid, and enabling the stirring blade 307 to always remain in an inclined state while rotating. The inclined stirring blade 307 helps to slide the perchloric acid mixed liquid attached thereto back into the tank body 1, thereby significantly reducing the residue of the mixed liquid on the stirring blade 307.
