Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0035] like Figures 1 to 12 As shown, the phosphogypsum mixing and stirring equipment of this embodiment includes: a support platform 1 and a transmission device 2.

[0036] like Figures 1 to 5As shown, a mixing tank 101 is fixed on the support platform 1. A main shaft 102 is mounted on the mixing tank 101, and the main shaft 102 drives the spiral mixing paddle 104 and the spiral scraper blade 105 to rotate. The spiral mixing paddle 104 is fixed inside the mixing tank 101 and is used to stir the phosphogypsum inside the mixing tank 101. The spiral scraper blade 105 is attached to the inner wall of the mixing tank 101. A connecting rod 114 is fixed between the spiral scraper blade 105 and the main shaft 102. The main shaft 102 drives the spiral scraper blade 105 to rotate through the connecting rod 114, and the spiral scraper blade 105 scrapes off the phosphogypsum adhering to the inner wall of the mixing tank 101. A discharge pipe 106 is provided below the support platform 1 for discharging materials.

[0037] like Figures 1 to 5 As shown, the mixing tank 101 is equipped with a feed port 113 and a discharge port 103, which are used for feeding and discharging materials, respectively. A plug 112 is fixed on the discharge pipe 106 and inserted into the discharge port 103. When the equipment is running, the plug 112 is inserted into the discharge port 103 to prevent the phosphogypsum during mixing from flowing out of the discharge port 103. A pair of fixing blocks 110 are fixed at the bottom of the support platform 1, and a rotating shaft 111 is fixed between the pair of fixing blocks 110. One end of the discharge pipe 106 is rotatably mounted on the rotating shaft 111. The discharge pipe 106 rotates around the rotating shaft 111. When the discharge pipe 106 rotates, it drives the plug 112 to be inserted into or pulled out of the discharge port 103.

[0038] like Figures 1 to 5 As shown, a pair of sliding rods 107 are inserted into the support platform 1. A horizontal plate 108 and an arc-shaped rod 115 are fixed to the two ends of the sliding rods 107, respectively. The horizontal plate 108 drives the arc-shaped rod 115 to move up and down via the sliding rods 107. A feed tube 106 is mounted on the arc-shaped rod 115. Moving the arc-shaped rod 115 up and down causes the feed tube 106 to rotate around the pivot 111. A first screw 109 is inserted into the support platform 1. The first screw 109 is threadedly connected to the horizontal plate 108. An external drive device drives the first screw 109 to rotate, which in turn moves the horizontal plate 108 up and down.

[0039] like Figures 6 to 12As shown, the transmission device 2 is installed on the mixing tank 101. The transmission device 2 includes a support frame 201, which serves as a fixed support. A transmission shaft 202 is inserted into the support frame 201. When the equipment is in use, the transmission shaft 202 is driven by an external drive device. A first gear 203 and a third gear 205 are installed on the transmission shaft 202, and the transmission shaft 202 drives the first gear 203 and the third gear 205 to rotate. A second gear 204 is meshed on one side of the first gear 203, and the first gear 203 drives the second gear 204 to rotate. A second screw 213 is provided below the first gear 203. The second screw 213 is rotatably connected to the main shaft 102. A threaded sleeve gear 211 is threadedly connected to the second screw 213. By rotating the threaded sleeve gear 211 clockwise or counterclockwise, the second screw 213 moves up and down, and the second screw 213 drives the main shaft 102 to move up and down. The threaded sleeve gear 211 is provided with a first intermittent gear 209 and a second intermittent gear 210 on both sides. The first intermittent gear 209 and the second intermittent gear 210 intermittently mesh with the threaded sleeve gear 211, respectively driving the threaded sleeve gear 211 to rotate clockwise and counterclockwise.

[0040] like Figures 6 to 12 As shown, a rotating ring 212 is fixed on the second gear 204. The rotating ring 212 is rotatably mounted on the support frame 201. The rotating ring 212 is mounted on the support frame 201 to prevent the second gear 204 from moving up and down. Both the second gear 204 and the rotating ring 212 are mounted on the main shaft 102. A second limiting groove 217 is cut into the main shaft 102. A second limiting block 218 is fixed on the rotating ring 212. The second limiting block 218 is located in the second limiting groove 217. The second gear 204 drives the main shaft 102 to rotate by engaging the second limiting block 218 in the second limiting groove 217. When the main shaft 102 moves up and down, the second limiting block 218 also moves up and down in the second limiting groove 217, so that the second gear 204 can always drive the main shaft 102 to rotate, and the second limiting block 218 is always located in the second limiting groove 217.

[0041] like Figures 6 to 12As shown, a fixing member 214 is provided on the threaded gear 211, and the fixing member 214 is fixed on the mixing tank 101. The spiral stirring paddle 104 is used to restrict the position of the threaded gear 211 and prevent it from moving up and down. A first limiting groove 215 is carved on the second screw 213, and a first limiting block 216 is fixed on the fixing member 214. The first limiting block 216 is located in the first limiting groove 215. The first limiting block 216 is locked in the first limiting groove 215 to prevent the second screw 213 from rotating. When the second screw 213 does not rotate, the threaded gear 211 can drive the second screw 213 to move up and down when it rotates clockwise or counterclockwise. When the second screw 213 moves up and down, the first limiting block 216 also moves up and down in the first limiting groove 215, and the first limiting block 216 is always located in the first limiting groove 215.

[0042] like Figures 6 to 12 As shown, a fifth gear 207 is fixed on the second intermittent gear 210. The fifth gear 207 meshes with the third gear 205. When the third gear 205 rotates, it drives the fifth gear 207 to rotate, and the fifth gear 207 drives the second intermittent gear 210 to rotate. A sixth gear 208 is fixed on the first intermittent gear 209. A fourth gear 206 is arranged between the sixth gear 208 and the third gear 205. The fourth gear 206 meshes with both the sixth gear 208 and the third gear 205. The third gear 205 drives the sixth gear 208 to rotate through the fourth gear 206, and the sixth gear 208 drives the first intermittent gear 209 to rotate. The third gear 205, the fourth gear 206, the fifth gear 207, and the sixth gear 208 are all gears of the same size. The first intermittent gear 209 and the second intermittent gear 210 are intermittent gears of the same size.

[0043] Working principle: Before using the equipment, first connect the first screw 109 and the drive shaft 202 to external drive devices to drive the first screw 109 and the drive shaft 202 to rotate. Before adding phosphogypsum, first drive the first screw 109 to rotate through the external drive device. The first screw 109 drives the horizontal plate 108 to move upward. The horizontal plate 108 drives the arc rod 115 to move upward through a pair of slide rods 107. The arc rod 115 drives the outlet end of the feed pipe 106 to move upward. The feed pipe 106 rotates upward around the rotating shaft 111 as the axis. The feed pipe 106 drives the plug 112 to be inserted into the discharge port 103. Then turn off the external drive device of the first screw 109. Then add the phosphogypsum to be stirred into the mixing tank 101 through the feeding port 113.

[0044] Then, the external drive device connected to the drive shaft 202 is started, which drives the drive shaft 202 to rotate. The drive shaft 202 drives the first gear 203 and the third gear 205 to rotate. The first gear 203 drives the second gear 204 to rotate. The second gear 204 drives the main shaft 102 to rotate. The main shaft 102 drives the spiral stirring paddle 104 and the spiral scraper 105 in the mixing tank 101 to rotate. The spiral stirring paddle 104 stirs the phosphogypsum in the mixing tank 101, and the spiral scraper 105 scrapes off the phosphogypsum adhering to the inner wall of the mixing tank 101.

[0045] Simultaneously, the third gear 205 drives the fourth gear 206 and the fifth gear 207 to rotate in the same direction. The fifth gear 207 drives the second intermittent gear 210 to rotate in the same direction. The fourth gear 206 drives the sixth gear 208 to rotate in the opposite direction. The sixth gear 208 drives the first intermittent gear 209 to rotate in the opposite direction. At this time, the second intermittent gear 210 and the first intermittent gear 209 rotate clockwise and counterclockwise at the same speed. The first intermittent gear 209 and the second intermittent gear 210 intermittently mesh with the threaded sleeve gear 211, respectively driving the threaded sleeve gear 211 to rotate clockwise and counterclockwise. The threaded sleeve gear 211 drives the second screw 213 to move up and down. The second screw 213 drives the main shaft 102 to move up and down. The main shaft 102 drives the spiral stirring paddle 104 and the spiral scraper blade 105 in the mixing tank 101 to rotate and move up and down at the same time, so as to fully stir the phosphogypsum in the mixing tank 101.

[0046] After mixing is completed, the first screw 109 is rotated in the reverse direction to drive the horizontal plate 108 to move downward. The horizontal plate 108 drives the arc rod 115 to move downward through the slide rod 107. As the arc rod 115 moves downward, the feed pipe 106 rotates downward around the rotating shaft 111 by its own gravity. The feed pipe 106 drives the plug 112 to be pulled out from the discharge port 103. Then, the phosphogypsum that has been mixed in the mixing tank 101 flows into the feed pipe 106 from the discharge port 103. At this time, the transport equipment only needs to catch the phosphogypsum at the opening of the feed pipe 106.
