Description

Technical Field

[0001] This utility model relates to the field of harmless treatment technology of phosphogypsum, specifically to a harmless treatment device for phosphogypsum. Background Technology

[0002] Phosphogypsum is a solid waste produced in the wet process of phosphoric acid production. The indiscriminate discharge and accumulation of phosphogypsum seriously damages the ecological environment and pollutes groundwater resources. When treating phosphogypsum, it is usually mixed with lime.

[0003] For example, the Chinese Patent Publication No. CN214289979U discloses a harmless treatment device for phosphogypsum. Its specific content is as follows: A servo motor is started, causing its output end to rotate. This rotation drives a lower pulley, which in turn drives an upper pulley via a transmission belt. The upper pulley then drives a first connecting rod, which in turn rotates two cams. This rotation causes two second connecting rods to reciprocate within two rotating wheels. This reciprocating motion of the wheels drives the two second connecting rods to reciprocate, which in turn causes the mixing chamber to reciprocate. A drive motor is then started, causing a second rotating rod to rotate. This rotation of the second rotating rod causes multiple stirring rods to rotate, ensuring thorough mixing and reaction of lime and phosphogypsum. Ultimately, this achieves thorough mixing and reaction of phosphogypsum and lime. However, it still has the following technical problems:

[0004] After each mixing cycle, the phosphogypsum in the mixing chamber needs to be manually removed. Then, lime and phosphogypsum are added again and mixed. This process is repeated, making the mixing of phosphogypsum and lime a rather cumbersome operation. Utility Model Content

[0005] Therefore, this utility model provides a harmless treatment device for phosphogypsum to solve the problem that the mixing operation of phosphogypsum and lime in the prior art is relatively cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for the harmless treatment of phosphogypsum includes a harmless treatment box;

[0008] The interior of the harmless treatment box is equipped with a feeding belt, a weighing belt, and a phosphogypsum conveyor belt for transporting phosphogypsum.

[0009] The interior of the harmless treatment box is equipped with a screw conveyor for conveying phosphogypsum mixed with reagents.

[0018] The present invention has the following advantages:

[0019] Phosphogypsum is transported by truck to a phosphogypsum stockpile for zoned stacking. After zoned testing, the phosphogypsum is shoveled onto the feeding port by a loader and conveyed to the weighing belt via a feeding belt. After weighing, the phosphogypsum enters the phosphogypsum conveyor belt. Based on the initial content of the main characteristic factors of the phosphogypsum detected in the zoned testing, a certain proportion of reagent is prepared and added into the reagent tank. The reagent is then sprayed onto the phosphogypsum on the phosphogypsum conveyor belt through nozzles on the spray pipe. The phosphogypsum is then conveyed by a screw conveyor to a twin-shaft mixer for thorough mixing. Finally, the phosphogypsum falls onto the finished product conveyor belt for transport to the finished product stockpile. This invention eliminates the need for repeated manual removal of the phosphogypsum after mixing with the reagent, making the operation relatively simple. Attached Figure Description

[0043] When the motor 241 is started, the bevel gear 240, in conjunction with the connecting gear 273, drives the rotating ring 271 to rotate. The tooth block 272, in conjunction with the gear 263, synchronously drives the connecting rod 262 to rotate, causing the sealing plate 261 to rotate, thereby adjusting the leakage amount of the medicine through the medicine passage 251, and thus adjusting the delivery amount of the medicine according to the different thicknesses of phosphogypsum.

[0044] Phosphogypsum is transported by truck to the phosphogypsum stockpile for zoning. After zoning testing, the phosphogypsum is shoveled by a loader to the feeding port 110, and then conveyed to the weighing belt 2 via the feeding belt 1. After weighing, the phosphogypsum enters the phosphogypsum conveyor belt 3. According to the initial content of the main characteristic factors of the phosphogypsum detected in the zoning test, a certain proportion of reagent is prepared and added into the reagent tank 150. The reagent is then sprayed onto the phosphogypsum on the phosphogypsum conveyor belt 3 through the nozzle on the spray pipe 210. The phosphogypsum is then conveyed to the twin-shaft mixer 130 via the screw conveyor 120 for thorough mixing, and finally falls onto the finished product conveyor belt 4 for transport to the finished product stockpile.

[0045] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
