[0022] Example 2 like Figure 1 to Figure 6 As shown, the top grinding assembly 11 includes a first cylinder 111 and a sliding internal gear 1124. The first cylinder 111 is installed on the top of the main body 10. The output end of the first cylinder 111 is installed with a first sliding shaft 1111. The bottom of the first sliding shaft 1111 is installed with a rotating motor 112. The output end of the rotating motor 112 is installed with a rotating shaft 1122. The bottom of the rotating shaft 1122 is fixedly connected with a top grinding disc 112. The top of the top grinding disc 112 is fixedly connected with two symmetrically arranged feeding ports 1123. The bottom of the top grinding disc 112 is slidably equipped with a sliding internal gear 1124. The top of the sliding internal gear 1124 is fixedly connected with a plurality of circumferentially evenly distributed limit blocks 1125. A plurality of circumferentially evenly distributed springs 1126 are connected between the sliding internal gear 1124 and the top grinding disc 112, and a corresponding damper is arranged on the spring 1126.

[0023] like Figure 1 to Figure 6 As shown, the top grinding assembly 11 also includes a connecting circular plate 113, which is fixedly sleeved on the outer circumferential surface of the rotating shaft 1122, and two symmetrically arranged second cylinders 1131 are installed at the bottom of the connecting circular plate 113, and a second sliding shaft 1133 is installed at the output end of the second cylinder 1131. The bottoms of the two second sliding shafts 1133 are commonly connected to a discharge block 1131, and the discharge block 1131 is slidably assembled inside the top grinding disc 112.

[0024] like Figure 1 to Figure 8As shown, the bottom grinding assembly 12 includes a bottom grinding disc 121, a connecting shaft 122, a follower shaft 123 and a worm gear 124. The bottom grinding disc 121 is fixedly connected to the top of the stirring mechanism 2. A lower hopper 1211 and a water inlet trough 1212 are respectively provided inside the bottom grinding disc 121. The connecting shaft 122 and the follower shaft 123 are both rotatably installed inside the bottom grinding disc 121. The two ends of the connecting shaft 122 are respectively fixedly connected with an active bevel gear 1222 and a meshing gear 1221. One end of the follower shaft 123 is fixedly connected with a follower bevel gear 1233. The active bevel gear 1222 is meshed with the follower bevel gear 1233. A worm 1231 is fixedly sleeved on the outer circumference of the follower shaft 123. The worm wheel 124 is rotatably installed inside the bottom grinding disc 121. The worm 1231 is meshed with the worm wheel 124. Two symmetrically arranged scraping blades 1241 are fixedly connected to the bottom of the worm wheel 124.

[0025] like Figure 1 to Figure 8 As shown, the bottom of the top grinding frame and the top of the top grinding frame are in contact with each other, and the sliding internal gear 1124 and the meshing gear 1221 are meshed with each other.

[0026] In this embodiment, before the equipment is used and grinding is required, the raw materials of double metal hydroxide and low melting point salt are delivered to the interior of the top grinding disc 112 through two feed ports 1123 in proportion. After the internal raw materials are delivered to the top grinding disc 112, the second cylinder 1131 on the rotating shaft 1122 is turned on. The start of the second cylinder 1131 causes the second sliding shaft 1133 to slide. The sliding of the second sliding shaft 1133 causes the discharge block 1131 to slide, connecting the cavity on the top grinding disc 112 with the outside, so that the material in the top grinding disc 112 flows out to the interior of the bottom grinding assembly 12 and falls through the material directly above. It can effectively prevent the material from scattering before grinding. After the material falls into the bottom grinding assembly 12, the first cylinder 111 is turned on. The opening of the first cylinder 111 causes the first sliding shaft 1111 to slide, thereby fitting the top grinding disc 112 and the bottom grinding disc 121. During the fitting process, the sliding internal gear 1124 meshes with the meshing gear 1221, and then the rotating motor 112 is turned on (the rotating motor 112 is a self-locking motor, which is turned on after stopping rotation). The rotation of the rotating motor 112 causes the rotating shaft 1122 to rotate, and the rotation of the rotating shaft 1122 causes the top grinding disc 112 to rotate, thereby grinding the raw material. Grinding, at this time continue to open the first cylinder 111, so that the top grinding disc 112 descends, reducing the space between the top grinding disc 112 and the bottom grinding disc 121, and improving its grinding fineness. At this time, the sliding internal gear 1124 is in place and continues to rotate due to the spring 1126 and the limit block 1125. The rotation of the sliding internal gear 1124 drives the connecting shaft 122 to rotate through the meshing with the meshing gear 1221. The active bevel gear 1222 on the connecting shaft 122 and the follower bevel gear 1233 on the follower shaft 123 are meshed, driving the follower shaft 123 to rotate. The rotation of the follower shaft 123 makes the worm 12 31 rotates, the rotation of the worm 1231 meshes with the worm wheel 124, driving the worm wheel 124 to rotate. During the rotation of the worm wheel 124, the scraper blade 1241 thereon scrapes off the ground qualified material flowing out of the sieve hole in the bottom grinding disc 121, so that the material discharge is smoother and the material residue is prevented. After the grinding is completed, the rotating motor 112 stops rotating. At this time, the rotating motor 112 is self-locked and opened, and the meshing gear 1221 also stops in place due to the self-locking of the worm wheel 124 and the worm 1231, so that the sliding inner gear 1124 is meshed with the meshing gear 1221 during the next grinding.

[0028] like Figure 1 to Figure 11 As shown, the stirring mechanism 2 also includes a water distribution pipe 251, which is sleeved on the outer peripheral surface of the bottom grinding disc 121, and four circumferentially evenly distributed nozzles 252 are installed on the inner wall of the water distribution pipe 251. The nozzles 252 are arranged inside the water inlet trough 1212, and one side of the water distribution pipe 251 is fixedly connected to the water inlet pipe 25.

[0029] In this embodiment, the ground material falls into the interior of the mixing frame 21 through the lower hopper 1211. After the material is ground and falls into the interior of the mixing frame 21, the water pump and the distilled water tank connected to the water inlet pipe 25 are used to enter water. The distilled water flows from the nozzle 252 into the water tank 1212 through the water distribution pipe 251, and then the water tank 1212 flows to the interior of the mixing frame 21. After entering the water, the servo motor 23 in the mixing frame 21 rotates, and the rotation of the servo motor 23 causes the planetary gear 231 to rotate. The rotation of the planetary gear 231 is connected to the The meshing of the sun gear 221 and the inner gear ring 24 drives the sun gear 221 and the inner gear ring 24 to rotate. The rotation of the sun gear 221 and the inner gear ring 24 causes the internal heating stirring block 222 and the external heating stirring block 241 thereon to heat, rotate and stir. After the stirring is completed, the two rotating shafts 26 are turned on, and the rotation of the rotating shafts 26 causes the discharge gate 261 to rotate. At this time, the servo motor 23 is turned on, and the internal heating stirring block 222 and the external heating stirring block 241 continue to rotate, delivering the material to the discharge gate 261 and to the interior of the drying mechanism 3.

[0031] In this embodiment, after the material falls into the drying mechanism 3, the rotating motor 32 and the heating base plate 322 are turned on. The turning on of the rotating motor 32 causes the turntable 321 to rotate.

During the drying process, the water mist flows out from the mist outlet 35. During the heating process, the rotating motor 32 is turned on every half hour to cause the turntable 321 to rotate again. At this time, the first hydraulic cylinder 33 is started to cause the sliding block 331 to slide, thereby causing the combing block 332 to slide, and the material is distributed again, thereby increasing the heating of the material. After the drying is completed, the staff opens the opening and closing door 312, and then turns on the rotating motor 32 and the second hydraulic cylinder 34.
