[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-9 This invention provides a technical solution: including a base 1, with two side plates 2 connected to the top of the base 1, and a desulfurization chamber 3, a decarbonization chamber 4, and a decalcification chamber 5 connected between the side plates 2. Horizontal plates 6 are connected to both sides of the desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5 to connect them together and ensure stable operation. A multi-probe ultrasonic generator 7 is connected to the top of one of the horizontal plates 6, and the probes of the multi-probe ultrasonic generator 7 are respectively connected to the corresponding desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5. A cleaning water pipe 8 is connected to one side of each of the desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5, with the bottom end of the cleaning water pipe 8 connected to the same pipeline. An auxiliary agent pipe 9 is connected to the other side. Through holes are opened on one side of the 2 corresponding to the pipeline and the auxiliary agent pipe 9 to facilitate the extension of the pipeline and the auxiliary agent pipe 9. The other end of the auxiliary agent pipe 9 is connected to the corresponding auxiliary agent source, and the other end of the cleaning water pipe 8 is connected to an external water source.

[0033] Each of the desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5 has a horizontal shaft 10 rotatably mounted inside. The ends of the horizontal shafts 10 that are close to each other pass through the corresponding desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5 and are connected by flanges, allowing them to rotate synchronously. A stirring mechanism 11 is connected to one end of each horizontal shaft 10. When the horizontal shaft 10 rotates, it drives the stirring mechanism 11 to rotate, turning and agitating the materials in the desulfurization chamber 3, decarbonization chamber 4, and decalcification chamber 5. One end of the horizontal shaft 10 in the decalcification chamber 5 passes through the corresponding side plate 2 and is connected to a pulley 12. One end of the horizontal shaft 10 in the desulfurization chamber 3 passes through the corresponding side plate 2 and is connected to a speed sensor 13. During operation, the speed sensor 13 can detect the rotational speed. The top of the decarbonization chamber 3, decalcification chamber 4 and decalcification chamber 5 are all connected to a feed hopper 14 and the bottom of each is connected to a discharge pipe 15. A valve is connected to one end of the feed hopper 14 and the discharge pipe 15. Two drive motors 16 are connected to one side of the side plate 2. The top of the base 1 is connected to two sets of movable rails 17. Two sets of positioning mechanisms 18 are slidably installed in the movable rails 17. The top of one of the positioning mechanisms 18 is connected to a feeding mechanism 20. The inner side of the feeding mechanism 20 is connected to a storage mechanism 21. The bottom of the base 1 is connected to a water storage tank 22. A filter screen 221 is connected to the inner side of the water storage tank 22. After the wastewater is discharged from the desulfurization chamber 3, decarbonization chamber 4 and decalcification chamber 5, it can be discharged into the water storage tank 22.

[0034] Reference Figure 3As shown, a defoaming pipe 31 is connected to one side of the desulfurization chamber 3, and a foam pump is connected to the other end of the defoaming pipe 31 to discharge the flotation foam. A fixing frame 32 is connected between the inner walls of the defoaming pipe 31, and a compression spring 33 is connected to one side of the fixing frame 32. A sealing plate 35 is connected to the other end of the compression spring 33. Figure 3 As can be seen, one side of the sealing plate 35 is chamfered to facilitate positioning and sealing with the desulfurization chamber 3. A guide assembly 34 is connected between the sealing plate 35 and the fixing frame 32. The guide assembly 34 consists of a conduit and a guide rod, which are respectively connected to the corresponding sealing plate 35 and fixing frame 32. A liquid level sensor 36 is connected to one side of the inner wall of the desulfurization chamber 3, located below the sealing plate 35. An air injection pipe 301 is connected to one side of the desulfurization chamber 3. After adding xanthate (such as ethyl xanthate) and foam adhesive into the desulfurization chamber 3 and stirring, the xanthate can react with the sulfides in the slurry. The process involves combining the foaming agent to make the sulfide surface hydrophobic, injecting air into the desulfurization chamber 3 through the air injection pipe 301, thereby generating foam through the foaming agent and combining it with the hydrophobic sulfide particles that have been treated with the agent. Water is injected to ensure that the water level in the desulfurization chamber 3 is at least level with the liquid level sensor 36. Then, the external foam pump is started to extract the foam in the desulfurization chamber 3 through the foam discharge pipe 31. When the foam discharge pipe 31 is under suction, a negative pressure is formed inside, thereby pulling the sealing plate 35 to extract the foam in the desulfurization chamber 3. After the foam discharge is completed, the compression spring 33 will push the sealing plate 35 back to its original position to ensure the sealing of the desulfurization chamber 3.

[0035] Reference Figure 1 As shown, a motor frame is connected to one side of the side plate 2, and the drive motor 16 is fixedly installed on the top of the motor frame. Each output end of the drive motor 16 is connected to a pulley 171. A belt is sleeved between the pulley 171 and the pulley 12. In use, the two sets of drive motors 16 can better drive the pulley 12 to rotate through the belt, so that the horizontal shaft 10 in each processing chamber rotates to agitate the slurry.

[0036] Reference Figure 7 As shown, one end of the cleaning water pipe 8 and the auxiliary agent pipe 9 extends into the corresponding desulfurization chamber 3, decarbonization chamber 4 and decalcification chamber 5, and is connected to a nozzle 141. Clean water can be sprayed into the treated slurry through the cleaning water pipe 8 to clean it, and the auxiliary agent pipe 9 makes it easier to add the corresponding auxiliary agent. The auxiliary agent pipe 9 is set independently.

[0037] Reference Figure 4-5As shown in the figure, the feeding mechanism 20 includes an outer ring frame 201. Multiple connecting plates 200 are connected to the outer surface of the outer ring frame 201. A servo motor 202 is connected to one side of each connecting plate 200. A drive gear 203 is connected to the output end of each servo motor 202. A rotating groove 23 is formed on the inner side of the outer ring frame 201, and an inner ring frame 204 is rotatably mounted within the groove 23. A rack 205 is provided on one side of the inner ring frame 204. As can be seen from the attached figure, multiple holes are formed on the surface of the outer ring frame 201. One side of the drive gear 203 passes through these holes and meshes with the rack 205. A storage mechanism 21 is fixedly mounted inside the inner ring frame 204. Side rails 208 are connected to both ends of the inner side of the outer ring frame 201. The servo motor 202 drives the drive gear... The wheel 203 rotates, thereby driving the inner ring frame 204 to rotate within the rotating groove 23 through meshing with the rack 205, which in turn drives the storage mechanism 21 to rotate, switching the feeding and receiving positions. The storage mechanism 21 includes a storage bin 211 fixedly installed on one side of the inner ring frame 204. An inspection door 212 is hinged to one side of the storage bin 211. A transfer hopper 213 is connected to the top of the storage bin 211, and a connecting plate 214 is connected to the middle of the transfer hopper 213. The part connecting the transfer hopper 213 and the connecting plate 214 is a retractable corrugated pipe, and a valve is also connected to the bottom of the corrugated pipe. A telescopic rod 215 is connected to the bottom of the connecting plate 214, and the telescopic rod 215 is fixedly installed on the top of the storage bin 211. Figure 4 As can be seen, the storage bin 211 has protruding parts on both sides, and the inner side of the side rail 208 has a sliding groove, so the storage bin 211 can be slidably connected to the side rail 208. When the storage bin 211 is at the bottom, the slurry or mineral discharged from the discharge pipe 15 of the corresponding processing bin can be received by the transfer bucket 213. When the feeding mechanism 20 rotates with the storage mechanism 21 to the top of the next processing bin, the telescopic rod 215 extends and pushes the transfer bucket 213 to align with the corresponding feed bucket 14, and then the valve is opened to allow the slurry or mineral to enter the corresponding processing bin, realizing automatic feeding and receiving, and ensuring automated processing.

[0038] Reference Figure 9 As shown, a heat insulation chamber 41 is connected to one side of the decarbonization chamber 4, and a magnetron 42 is connected between the inner walls of the heat insulation chamber 41. A glass plate 43 is connected to one side of the heat insulation chamber 41. The magnetron 42 emits microwaves to heat the minerals in the decarbonization chamber 4, so as to facilitate decarbonization.

[0039] Reference Figure 1 and Figure 2 As shown, protective frames are connected to both sides of the desulfurization chamber 3, decarbonization chamber 4 and decalcification chamber 5. The horizontal plate 6 is fixedly connected to the protective frame, which can ensure the connectivity and stability between the desulfurization chamber 3, decarbonization chamber 4 and decalcification chamber 5 during use.

[0040] Reference Figure 6As shown, the stirring mechanism 11 includes a stirring shell 111. Side holes 112 are provided on both sides of the stirring shell 111. A filter hole 113 is connected to one side of the stirring shell 111, and a flap 114 is connected to one side of the inner wall of the stirring shell 111. When the stirring shell 111 rotates with the horizontal shaft 10, the flap 114 can stir the slurry, so that the additives and the slurry can be better mixed. Moreover, the liquid after the slurry is processed can be filtered and discharged through the side holes 112 and the filter holes 113.

[0041] Reference Figure 8 As shown, a cylinder 19 is connected to one side of the positioning mechanism 18. The output end of the cylinder 19 passes through one set of positioning mechanisms 18 and is connected to another set of positioning mechanisms 18. The two sets of positioning mechanisms 18 can switch between working. When the cylinder 19 is working to extend and retract, it can move the feeding mechanism 20.

[0042] Reference Figure 8 As shown, the positioning mechanism 18 includes a support base 181, and two sets of connecting arms 182 are slidably arranged on the inner side of the support base 181. Anti-slip positioning strips 183 are connected to the ends of the connecting arms 182 that are far apart from each other. (Refer to...) Figure 8 It can be seen that the anti-slip positioning strip 183 has anti-slip teeth on one side, and the two sets of connecting arms 182 have teeth 184 on the side that are close to each other. A central gear 185 is rotatably installed on one side of the bottom of the support base 181. Both sides of the central gear 185 mesh with the teeth 184. An electric actuator 186 is connected to the bottom of the support base 181. The output end of the electric actuator 186 is connected to the anti-slip positioning strip 183. As can be seen from the attached figure, a support plate is connected to one side of the inner wall of the support base 181, and one end of the electric actuator 186 is connected to the support plate. The support base 181 is fixedly connected to a baffle 187 at its bottom. An electric push rod 186 extends and pushes the anti-slip positioning strip 183 on one side to move, thereby driving the corresponding connecting arm 182 to move. The gear 184 drives the central gear 185 to rotate, thereby causing the other set of connecting arms 182 to move. This allows the two anti-slip positioning strips 183 to move synchronously in opposite directions, so that the anti-slip positioning strips 183 abut against one side of the inner wall of the movable track 17, thereby fixing the positioning mechanism 18 inside the movable track 17.

[0043] The implementation principle of this application is as follows: When in use, ultra-low grade bauxite to be processed is injected into the storage silo 211. The feeding mechanism 20 drives the storage mechanism 21 to rotate above the dewatering chamber 3. Then, the telescopic rod 215 pushes the transfer hopper 213 to connect with the feed hopper 14, opening the valve to inject the mineral or slurry into the dewatering chamber 3. After injection, the storage mechanism 21 returns to its lower position. Then, xanthate and foaming agent are injected into the dewatering chamber 3 through the additive pipe 9. After injection, the drive is activated. The motor 16 drives the pulley 12 to rotate via a belt, which in turn drives the horizontal shaft 10 to rotate the stirring mechanism 11 for agitation. Air is then injected into the dewatering chamber 3 through the air injection pipe 301, generating foam that carries away sulfide particles. The foam pump is then activated to extract the foam. Clean water is then injected into the dewatering chamber 3 through the cleaning water pipe 8 for cleaning. Before cleaning, the discharge pipe 15 is opened to filter out the water from the slurry and discharge it into the water storage tank 22. After cleaning, the output end of the cylinder 19... The positioning mechanism 18 is fixed against the moving track 17. Then, the cylinder 19 extends, driving the positioning mechanism 18 on one side of the cylinder 19 to move, thereby moving the feeding mechanism 20 to below the dewatering chamber 3, opening the valve, and rotating the stirring mechanism 11 to the top, so that the mineral or slurry is discharged into the storage mechanism 21. Then, it moves to the position of the decarbonization chamber 4 again, and at the same time, the storage mechanism 21 moves to the top, injecting the slurry into the decarbonization chamber 4 in the same way. Then, sulfuric acid or hydrochloric acid is injected into the decarbonization chamber 4 through the auxiliary agent pipe 9, and stirring is carried out. It is heated by the magnetron 42 for decarbonization treatment. Then, it is washed and discharged again, accepted by the storage mechanism 21, and discharged into the decalcification chamber 5. Sulfuric acid or hydrochloric acid is injected into the decalcification chamber 5 through the auxiliary agent pipe 9 for decalcification treatment. At the same time, the multi-probe ultrasonic generator 7 is turned on, and ultrasonic waves are used to make the auxiliary agent and slurry more fully integrated into the dewatering chamber 3, decarbonization chamber 4 and decalcification chamber 5, improving the processing efficiency.
