Technical Field
[0001] This utility model relates to the technical field of neutralization and purification devices, specifically a high-purity phosphogypsum neutralization and purification device. Background Technology
[0002] Phosphogypsum is a solid waste residue produced during the treatment of phosphate rock with sulfuric acid in phosphoric acid production. Its main component is calcium sulfate. The main component of phosphogypsum is CaSO4·2H2O, and it also contains various other impurities. Phosphogypsum is generally in powder form, with an appearance typically grayish-white, grayish-yellow, or light green. It also contains organic phosphorus and sulfur-fluorine compounds, with a bulk density of 0.733–0.88 g / cm3 and a particle diameter of 5–15 μm. Its main component is calcium sulfate dihydrate, which typically accounts for 70%–90% of its composition. The minor components vary depending on the phosphate rock origin, but it generally contains phosphates and silicates of the rock components Ca and Mg.
[0003] A high-purity phosphogypsum neutralization and purification device, as proposed in Chinese Patent CN207227031U, includes a device body. The inner wall of the device body has a heat insulation layer, and the inner wall of the heat insulation layer has a heating layer. The inner wall of the heating layer has a working chamber. The top surface of the working chamber has a feed inlet, and one side of the feed inlet has a drive motor. One end of the drive motor has a transmission shaft, and the surface of the transmission shaft has stirring blades. One side of the drive motor has a lime feed inlet, and one side of the lime feed inlet has a water inlet. The bottom of the working chamber has a discharge outlet, and one end of the discharge outlet has a valve. This high-purity phosphogypsum neutralization and purification device significantly reduces harmful impurities in phosphogypsum by first calcining it, then neutralizing it with lime, and finally hydrating it. The product performance is superior to that of natural gypsum. This solves the problems of environmental pollution and low recycling rate associated with existing phosphogypsum products.
[0004] However, there are still some shortcomings in this patent. In the process of stirring lime and phosphogypsum by rotating the drive shaft, some lime and phosphogypsum tend to adhere to the inner wall of the device body, resulting in insufficient mixing of lime and phosphogypsum and thus affecting the neutralization and purification effect of phosphogypsum. Therefore, we propose a high-purity phosphogypsum neutralization and purification device. Utility Model Content
[0005] The purpose of this invention is to provide a high-purity phosphogypsum neutralization and purification device, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-purity phosphogypsum neutralization and purification device, comprising a mounting plate, a processing tank disposed above the mounting plate, and a vibration assembly disposed outside the processing tank. The vibration assembly includes a column fixedly connected to the top of the mounting plate, a top plate fixedly connected to the top of the column, a fixed seat fixedly connected to the right side of the top plate, a first drive motor fixedly connected to the inner wall of the other side of the fixed seat, a first output shaft fixedly connected to the output end of the first drive motor, a gear fixedly connected to the bottom outer wall of the first output shaft, a gear ring meshing with the side wall of the gear, a rotating ring fixedly connected to the inner wall of the gear ring, and the top inner wall of the rotating ring sliding. A limiting block is connected, with its top fixedly connected to the bottom of the top plate. A first protrusion is fixedly connected to the bottom of the rotating ring, and a second protrusion is slidably connected to the bottom of the first protrusion. A fixing ring is fixedly connected to the bottom of the second protrusion, and the inner wall of the fixing ring is fixedly connected to the outer wall of the treatment tank. A sleeve is fixedly connected to the top of the mounting plate, and a spring is fixedly connected to the bottom of the inner wall of the sleeve. A limiting rod is fixedly connected to the other end of the spring, and the top of the limiting rod is fixedly connected to the bottom of the treatment tank. By setting a vibration component, the treatment tank can be vibrated, thereby preventing the phosphogypsum from adhering to the inner wall of the treatment tank during the mixing of phosphogypsum and lime, which would affect the neutralization and purification effect of the phosphogypsum.
[0007] Preferably, the processing tank is equipped with a processing assembly, which includes a second drive motor fixedly connected to the top of the processing tank. The output end of the second drive motor is fixedly connected to a second output shaft, which movably passes through the top of the processing tank and extends into the interior of the processing tank. A stirring blade is fixedly connected to the outer wall of the second output shaft. A feed hopper is connected to the top of the processing tank, and a discharge hopper is connected to the bottom of the processing tank. A solenoid valve is fixedly connected to the bottom outer wall of the discharge hopper. By setting up the processing assembly, when it is necessary to stir phosphogypsum and lime, the operator puts phosphogypsum and lime into the processing tank through the feed hopper, and then turns on the second drive motor to make the second output shaft rotate. During the rotation of the second output shaft, the stirring blade will rotate, thereby realizing the stirring and mixing of phosphogypsum and lime inside the processing tank.
[0008] Preferably, the processing assembly further includes a heating generator fixedly connected to the top of the inner wall of the processing tank. The heating generator is located above the stirring blades. By setting up the heating generator, after the phosphogypsum and lime are hydrated, the heating generator is activated to heat and dry the phosphogypsum, thereby obtaining phosphogypsum with higher purity and achieving the purpose of neutralizing and purifying the phosphogypsum.
[0009] Preferably, a water storage tank is fixedly connected to the top of the top plate, and a pump body is fixedly connected to the top of the water storage tank. The input end of the pump body is connected to the top of the water storage tank, and a connecting pipe is connected to the output end of the pump body. The other end of the connecting pipe is connected to the top of the processing tank. When it is necessary to hydrate phosphogypsum and lime, the operator starts the pump body, which causes the pump body to discharge the water inside the water storage tank into the water storage tank through the connecting pipe, thereby hydrating the phosphogypsum and lime and producing phosphogypsum with higher purity.
[0010] Preferably, a drain pipe is connected to the outer wall of the left side of the treatment tank, and a valve is fixedly connected to the outer wall of the other end of the drain pipe. After the phosphogypsum is neutralized and purified, the operator opens the valve to allow the hydrated water to be discharged from the drain pipe.
[0011] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixed at the four corners of the bottom of the mounting plate. By setting four support legs at the bottom of the mounting plate, a stable support function for the device can be achieved.
[0012] This invention provides a high-purity phosphogypsum neutralization and purification device. This high-purity phosphogypsum neutralization and purification device has the following beneficial effects:
[0013] This high-purity phosphogypsum neutralization and purification device, by incorporating a vibration component, requires mixing phosphogypsum and lime in a processing tank before neutralization and purification. To prevent the phosphogypsum and lime from adhering to the inner wall of the processing tank during mixing, the tank needs to be vibrated. First, the operator starts the first drive motor, causing the first output shaft to rotate. During this rotation, the gear and gear ring mesh. A limiting block restricts the rotation of the ring and gear ring, causing the gear to rotate and in turn causing the rotating ring to rotate. This rotation causes the first protrusion to rotate, which in turn presses against the second protrusion, causing the processing tank to press against the limiting rod. This, in turn, compresses the spring, resulting in up-and-down vibration of the processing tank. This effectively prevents the phosphogypsum and lime from adhering to the inner wall of the processing tank during mixing, thus improving the mixing effect.
[0014] This high-purity phosphogypsum neutralization and purification device, through the inclusion of processing components, allows operators to feed phosphogypsum and lime into a processing tank via a feed hopper when mixing is required. The second drive motor is then activated, causing the second output shaft to rotate. This rotation of the output shaft drives the stirring blades, thus mixing the phosphogypsum and lime within the processing tank. When hydration of the phosphogypsum and lime is needed, the operator activates a pump to pump water from a storage tank through a connecting pipe, hydrating the phosphogypsum and lime to produce a higher-purity phosphogypsum. Finally, a heating generator is installed to heat and dry the phosphogypsum after hydration, resulting in an even higher-purity phosphogypsum and achieving the neutralization and purification of the phosphogypsum.

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0022] A preferred embodiment of the high-purity phosphogypsum neutralization and purification device provided by this utility model is, for example... Figures 1 to 5 As shown: A high-purity phosphogypsum neutralization and purification device includes a mounting plate 1, a processing tank 4 disposed above the mounting plate 1, and a vibration assembly 31 disposed outside the processing tank 4. The vibration assembly 31 includes a column 311 fixedly connected to the top of the mounting plate 1, a top plate 312 fixedly connected to the top of the column 311, a fixed seat 313 fixedly connected to the right side of the top plate 312, a first drive motor 314 fixedly connected to the inner wall of the other side of the fixed seat 313, a first output shaft 315 fixedly connected to the output end of the first drive motor 314, a gear 316 fixedly connected to the bottom outer wall of the first output shaft 315, a gear ring 317 meshing with the side wall of the gear 316, and a rotating gear fixedly connected to the inner wall of the gear ring 317. Ring 318, the top inner wall of the rotating ring 318 is slidably connected to a limiting block 319, the top of the limiting block 319 is fixedly connected to the bottom of the top plate 312, the bottom of the rotating ring 318 is fixedly connected to a first protrusion 3110, the bottom of the first protrusion 3110 is slidably connected to a second protrusion 3111, the bottom of the second protrusion 3111 is fixedly connected to a fixing ring 3112, the inner wall of the fixing ring 3112 is fixedly connected to the outer wall of the processing tank 4, the top of the mounting plate 1 is fixedly connected to a sleeve 3113, the bottom of the inner wall of the sleeve 3113 is fixedly connected to a spring 3114, the other end of the spring 3114 is fixedly connected to a limiting rod 3115, the top of the limiting rod 3115 is fixedly connected to the bottom of the processing tank 4;
[0023] By setting up the vibration component 31, before neutralizing and purifying the phosphogypsum, the phosphogypsum and lime need to be stirred and mixed in the treatment tank 4. To prevent the phosphogypsum and lime from adhering to the inner wall of the treatment tank 4 during the mixing process, the treatment tank 4 needs to be vibrated. First, the operator turns on the first drive motor 314, causing the first output shaft 315 to rotate. During the rotation of the first output shaft 315, the gear 316 and the gear ring 317 will mesh. Under the limiting action of the limiting block 319, the rotating ring 318 and the gear ring 317 will be limited, thus causing... Gear 316 drives gear ring 317 to rotate, which in turn drives rotating ring 318 to rotate. During the rotation of rotating ring 318, the first protrusion 3110 will rotate, and the first protrusion 3110 will squeeze the second protrusion 3111, causing the processing barrel 4 to squeeze the limiting rod 3115, which in turn causes the limiting rod 3115 to compress the spring 3114, thereby achieving up-and-down vibration of the processing barrel 4. This prevents phosphogypsum and lime from adhering to the inner wall of the processing barrel 4 during the mixing process, effectively improving the mixing effect of phosphogypsum and lime.
[0024] A preferred embodiment of the high-purity phosphogypsum neutralization and purification device provided by this utility model is, for example... Figures 1 to 5As shown: The processing tank 4 is equipped with a processing component 32. The processing component 32 includes a second drive motor 321 fixedly connected to the top of the processing tank 4. The output end of the second drive motor 321 is fixedly connected to a second output shaft 322. The second output shaft 322 movably passes through the top of the processing tank 4 and extends into the interior of the processing tank 4. A stirring blade 323 is fixedly connected to the outer wall of the second output shaft 322. A feed hopper 325 is connected to the top of the processing tank 4. A discharge hopper 3211 is connected to the bottom of the processing tank 4. A solenoid valve 3212 is fixedly connected to the bottom outer wall of the discharge hopper 3211.
[0025] By setting up the processing component 32, when it is necessary to mix phosphogypsum and lime, the operator puts phosphogypsum and lime into the processing tank 4 through the feed hopper 325, and then turns on the second drive motor 321 to make the second output shaft 322 rotate. During the rotation of the second output shaft 322, it will drive the stirring blade 323 to rotate, thereby realizing the mixing of phosphogypsum and lime inside the processing tank 4.
[0026] The processing component 32 also includes a heating generator 324 fixedly connected to the top of the inner wall of the processing tank 4. The heating generator 324 is located above the stirring blade 323. By setting the heating generator 324, after the phosphogypsum and lime are hydrated, the heating generator 324 is activated to heat and dry the phosphogypsum, thereby obtaining phosphogypsum with higher purity and achieving the purpose of neutralizing and purifying the phosphogypsum.
[0027] Furthermore, a water storage tank 328 is fixedly connected to the top of the top plate 312, and a pump body 329 is fixedly connected to the top of the water storage tank 328. The input end of the pump body 329 is connected to the top of the water storage tank 328, and the output end of the pump body 329 is connected to a connecting pipe 3210. The other end of the connecting pipe 3210 is connected to the top of the processing tank 4. When it is necessary to hydrate phosphogypsum and lime, the operator starts the pump body 329, which causes the pump body 329 to discharge the water inside the water storage tank 328 into the water storage tank 328 through the connecting pipe 3210, thereby hydrating the phosphogypsum and lime and producing phosphogypsum with higher purity.
[0028] Furthermore, a drain pipe 326 is connected to the outer wall of the left side of the treatment tank 4. A valve 327 is fixedly connected to the outer wall of the other end of the drain pipe 326. After the phosphogypsum is neutralized and purified, the operator opens the valve 327 to allow the hydrated water to be discharged from the drain pipe 326.
[0029] In addition, four support legs 2 are fixedly connected to the bottom of the mounting plate 1. The four support legs 2 are fixedly connected at equal intervals at the four corners of the bottom of the mounting plate 1. By setting four support legs 2 at the bottom of the mounting plate 1, the device can be stably supported.
[0030] Working principle: Before neutralizing and purifying phosphogypsum, it is first necessary to stir and mix phosphogypsum and lime in treatment tank 4. To prevent the phosphogypsum and lime from adhering to the inner wall of treatment tank 4 during the mixing process, treatment tank 4 needs to be vibrated. First, the operator turns on the first drive motor 314, causing the first output shaft 315 to rotate. During the rotation of the first output shaft 315, the gear 316 and the gear ring 317 will mesh. Under the limiting action of the limiting block 319, the rotating ring 318 and the gear ring 317 will be limited, causing the gear 316 to mesh. 16 drives the toothed ring 317 to rotate, which in turn drives the rotating ring 318 to rotate. During the rotation of the rotating ring 318, the first protrusion 3110 will rotate, and the first protrusion 3110 will squeeze the second protrusion 3111, causing the processing barrel 4 to squeeze the limiting rod 3115, which in turn causes the limiting rod 3115 to compress the spring 3114, thereby realizing the up-and-down vibration of the processing barrel 4. This can prevent phosphogypsum and lime from adhering to the inner wall of the processing barrel 4 during the mixing process, effectively improving the mixing effect of phosphogypsum and lime.
[0031] When it is necessary to mix phosphogypsum and lime, the operator puts phosphogypsum and lime into the processing tank 4 through the feed hopper 325, and then turns on the second drive motor 321 to make the second output shaft 322 rotate. During the rotation of the second output shaft 322, the stirring blade 323 will be driven to rotate, thereby realizing the mixing of phosphogypsum and lime inside the processing tank 4.
[0032] When it is necessary to hydrate phosphogypsum and lime, the operator starts the pump body 329, which causes the pump body 329 to discharge the water inside the water storage tank 328 into the water storage tank 328 through the connecting pipe 3210, thereby hydrating the phosphogypsum and lime and producing phosphogypsum with higher purity.
[0033] By activating the heating generator 324, the phosphogypsum is heated and dried to obtain phosphogypsum with higher purity, thereby achieving the purpose of neutralizing and purifying the phosphogypsum.
[0034] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
