Description

Technical Field

[0001] This application relates to the field of phosphogypsum recycling technology, and more specifically, to a device for recycling phosphogypsum production waste. Background Technology

[0002] Phosphogypsum is a solid waste generated in the wet-process phosphoric acid production process. Its main component is calcium sulfate dihydrate. The composition of phosphogypsum is relatively complex. In addition to calcium sulfate, it also contains incompletely decomposed phosphate rock, residual phosphoric acid, fluorides, acid-insoluble substances, and organic matter. Among these, the presence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum. For example, a phosphogypsum production waste recycling device described in patent publication number CN221388087U uses a crushing device. The phosphogypsum waste is fed into the crushing box through the inlet. The motor rotates, driving the rotating rod to rotate, which in turn drives multiple crushing blades to rotate. The rotation of the crushing blades crushes the phosphogypsum waste, making subsequent extrusion and recycling easier. It is easier to extrude the phosphogypsum into blocks, and it also reduces the generation of air bubbles in the cavity, increases density, and makes it more convenient for workers to recycle.

[0003] However, this device is prone to causing accumulation when processing large quantities of phosphogypsum production waste. Furthermore, the phosphogypsum generates a large amount of dust during crushing, which pollutes the environment and affects the health of operators. In addition, the lack of screening of phosphogypsum leaves iron and some coarse particulate impurities inside, which affects the purity and quality of the phosphogypsum.

[0004] Therefore, a waste recycling device for phosphogypsum production is proposed to address the above problems. Summary of the Invention

[0041] In a preferred embodiment, the screening mechanism 5 includes a rotating rod 501, a screen plate 502, a connecting groove 503, a connecting block 504, a spring 505, a first protrusion 506, a second connecting rod 507, a first pulley 508, a third belt 509, a second pulley 510, a third connecting rod 511, and a second protrusion 512. The rotating rod 501 is fixedly connected inside the phosphogypsum recovery machine 1, and the screen plate 502 is rotatably connected to the surface of the rotating rod 501. Two sets of connecting grooves 502 are provided inside the feed hopper 2. 03. Two sets of connecting blocks 504 are fixedly connected to one end of the sieve plate 502. The connecting blocks 504 are movable inside the connecting groove 503. A spring 505 is provided on the surface of the connecting block 504. One end of the spring 505 is fixedly connected to the connecting groove 503, and the other end is fixedly connected to the connecting block 504. Two sets of first protrusions 506 are fixedly connected to one end of the sieve plate 502. A second connecting rod 507 is rotatably connected to one end of the phosphogypsum recycling machine 1. The second connecting rod 507 is fixedly connected inside the second transmission pulley 403.

[0042] In a preferred embodiment, a first pulley 508 is fixedly connected to the surface of the second connecting rod 507. A third belt 509 is provided on the surface of the first pulley 508. A second pulley 510 is provided inside the third belt 509. A third connecting rod 511 is fixedly connected inside the second pulley 510. One end of the third connecting rod 511 is rotatably connected to the phosphogypsum recycling machine 1. A second protrusion 512 is fixedly connected to the surfaces of the second connecting rod 507 and the third connecting rod 511. After the phosphogypsum is crushed, it falls onto the sieve plate 502. At this time, coarse impurities such as quartz sand in the phosphogypsum will be screened out by the sieve plate 502, causing the screened phosphogypsum to fall from the sieve plate 502. At the same time, the second transmission pulley 403 drives the first pulley 508 to rotate through the second connecting rod 507, causing the first pulley 508 to rotate through the third belt. 509 can drive the second pulley 510 and the third connecting rod 511 to rotate. The second connecting rod 507 and the third connecting rod drive the second protrusion 512 to rotate. When the second protrusion 512 rotates, the protrusion at the top pushes the first protrusion 506 to move one end of the screen plate 502 upward. At the same time, the screen plate 502 drives the connecting block 504 to compress the spring 505. When the protrusion at the top of the second protrusion 512 passes the first protrusion 506, the compressed spring 505 will reset and push the connecting block 504 downward, so that the connecting block 504 can move up and down in the connecting groove 503, causing the connecting block 504 to drive the screen plate 502 to vibrate. This process is repeated to discharge coarse particles and impurities on the screen plate 502 into the discharge plate 6 for discharge, while preventing the screen plate 502 from becoming blocked and affecting the passage of phosphogypsum.

[0043] In a preferred embodiment, the processing mechanism 7 includes a discharge port 701, a magnetic roller 702, a scraper 703, a collection box 704, and a handle 705.

A conveyor belt 706 is located inside the phosphogypsum recycling machine 1. After the phosphogypsum screening is completed... The phosphogypsum passes through the discharge port 701 and then through the magnetic roller 702. The rotation of the magnetic roller 702 causes the iron impurities inside the phosphogypsum to be magnetically attracted onto the magnetic roller 702. The magnetically separated phosphogypsum falls onto the conveyor belt 706 and is then conveyed into the mixing tank 10. At the same time, the iron impurities on the magnetic roller 702 are scraped off by the scraper 703 as they pass through the scraper and fall into the collection box 704. After the iron impurities are collected, the collection box 704 is pulled from the phosphogypsum recycling machine 1 by the handle 705 for subsequent processing of the iron impurities.

[0044] In a preferred embodiment, the dust collection mechanism 8 includes a dust collector 801, a dust collection pipe 802, a dust collection port 803, and a dust discharge pipe 804. The dust collector 801 is located on the top of the phosphogypsum recovery machine 1. One end of the dust collector 801 is fixedly connected to the dust collection pipe 802. The dust collection port 803 is located on one side of the phosphogypsum recovery machine 1 and the feeding hopper 2.

One end of the dust discharge pipe 804 is connected to the phosphogypsum recovery machine 1. When the phosphogypsum is crushed and sieved, a large amount of dust is generated. At this time, the dust collector 801 is activated, and the dust is absorbed into the dust collector 801 through the dust collection pipe 802 and the dust collection port 803. The dust is then discharged into the top of the mixing tank 10 through the dust discharge pipe 804 on the dust collector 801, thus avoiding environmental pollution and affecting the health of the operators.

[0045] In a preferred embodiment, the water spraying mechanism 9 includes a water pump 901, a water pipe 902, and a nozzle 903. One end of the phosphogypsum recovery machine 1 is equipped with a water pump 901, and the surface of the water pump 901 is equipped with a water pipe 902. One end of the water pipe 902 is fixedly connected to multiple sets of nozzles 903. When dust is discharged into the upper part of the mixing tank 10 through the dust outlet pipe 804 on the vacuum cleaner 801, water is pumped by the water pump 901, so that water is sprayed out through the water pipe 902 and the nozzle 903. At this time, the dust and water are mixed, and the dust falls into the mixing tank 10, thereby avoiding further processing of the dust. At the same time, water is sprayed on the phosphogypsum in the mixing tank 10 so that the phosphogypsum and water can be mixed in the future.

[0046] In a preferred embodiment, the stirring mechanism 11 includes a first rotating rod 1101, a second rotating rod 1102, a second gear 1103, and a stirring plate 1104. The first rotating rod 1101 is fixedly connected inside the auxiliary pulley 408. The first rotating rod 1101 and two sets of second rotating rods 1102 are rotatably connected inside the stirring tank 10. One end of the first rotating rod 1101 and the two sets of second rotating rods 1102 is fixedly connected to the second gear 1103. The surfaces of the first rotating rod 1101 and the two sets of second rotating rods 1102 are fixed. The mixing tank 10 is connected to a stirring plate 1104. After the phosphogypsum falls into the mixing tank 10, the auxiliary belt pulley 408 drives the first rotating rod 1101 and the second gear 1103 to rotate. The second gear 1103 then drives the remaining second gears 1103 to rotate, allowing the second rotating rod 1102 to rotate. The rotation of the first rotating rod 1101 and the second rotating rod 1102 prevents the phosphogypsum in the mixing tank 10 from piling up, allowing it to fully mix with the water phase, so that the phosphogypsum can be extruded into blocks later.

[0047] In a preferred embodiment, the discharge mechanism 12 includes a fixing groove 1201, a second drive motor 1202, a threaded rod 1203, a sliding rod 1204, and a fixing plate 1205. Two sets of fixing grooves 1201 are provided at the bottom of the mixing tank 10. One end of the fixing groove 1201 is fixedly connected to the second drive motor 1202, and one end of the second drive motor 1202 is fixedly connected to the threaded rod 1203. One end of the threaded rod 1203 is rotatably connected to the mixing tank 10, and one end of the mixing tank 10 is fixedly connected to the sliding rod 1204. 4. Two sets of fixing plates 1205 are threadedly connected to the surface of the threaded rod 1203, and the fixing plates 1205 are fixedly connected to the surface of the slide rod 1204. After the phosphogypsum is mixed, the second drive motor 1202 is started to drive the threaded rod 1203 to rotate. The fixing plates 1205 can be moved left and right through the threaded rod 1203, so that the fixing plates 1205 can be moved into the fixing groove 1201, so that the opening at the bottom of the mixing box 10 can be opened, and the mixed phosphogypsum can be discharged from the mixing box 10 for subsequent extrusion into blocks.

[0048] The working process of this application is as follows: Phosphogypsum is added to the feed hopper 2. The first drive motor 301 is started, driving the first fixed rod 302 to rotate. The first fixed rod 302 drives the second fixed rod 303 to rotate via the first gear 304. The first and second fixed rods 302 and 303 drive the crushing roller 305 to rotate, thus crushing the phosphogypsum. When the second fixed rod 303 rotates, it drives the first transmission pulley 401 to rotate. The first transmission pulley 401 drives the second transmission pulley 403 and the third transmission pulley 404 to rotate via the first belt 402. The third transmission pulley 404 drives the main pulley 406 to rotate via the first connecting rod 405, thus causing the main belt... Wheel 406 drives auxiliary pulley 408 to rotate via second belt 407. After the phosphogypsum is crushed, it falls onto sieve plate 502. At this time, coarse impurities such as quartz sand in the phosphogypsum are screened out by sieve plate 502, causing the screened phosphogypsum to fall from sieve plate 502. Simultaneously, second drive pulley 403 drives first pulley 508 to rotate via second connecting rod 507. First pulley 508 drives second pulley 510 and third connecting rod 511 to rotate via third belt 509. Second connecting rod 507 and third connecting rod drive second protrusion 512 to rotate. When second protrusion 512 rotates, the protrusion at the top pushes first protrusion 506, causing one end of sieve plate 502 to move upward. When the screen plate 502 drives the connecting block 504 to compress the spring 505, the spring 505 will reset and push the connecting block 504 downward when the protrusion at the top of the second protrusion 512 passes the first protrusion 506. This allows the connecting block 504 to move up and down in the connecting groove 503, causing the connecting block 504 to drive the screen plate 502 to vibrate. This process is repeated to discharge coarse particles on the screen plate 502 into the discharge plate 6 for discharge. This also prevents the screen plate 502 from becoming blocked and affecting the passage of phosphogypsum. After the phosphogypsum is screened, it passes through the discharge port 701 and then through the magnetic roller 702. The rotation of the magnetic roller 702 causes the iron impurities inside the phosphogypsum to be magnetically attracted to the magnetic roller 702, thus achieving magnetic separation. The phosphogypsum will fall onto conveyor belt 706 and be conveyed into mixing tank 10. Simultaneously, iron impurities on magnetic roller 702 will be scraped off by scraper 703 and fall into collection tank 704. After the iron impurities are collected, collection tank 704 is pulled from phosphogypsum recycling machine 1 by handle 705 for subsequent processing. A large amount of dust is generated during the crushing and sieving of phosphogypsum. At this time, vacuum cleaner 801 is activated, and the dust is absorbed into vacuum cleaner 801 through suction pipe 802 and suction port 803, and discharged into the top of mixing tank 10 through dust outlet pipe 804, preventing dust pollution and harm to operators' health.When dust is discharged into the mixing tank 10 through the dust outlet pipe 804 on the vacuum cleaner 801, water is drawn by the water pump 901, causing water to be sprayed out through the water pipe 902 and the nozzle 903. At this time, the dust and water mix, causing the dust to fall into the mixing tank 10, thus avoiding further dust processing. At the same time, the water sprayed onto the phosphogypsum in the mixing tank 10, so that the phosphogypsum can mix with the water later. After the phosphogypsum falls into the mixing tank 10, the secondary belt pulley 408 drives the first rotating rod 1101 and the second gear 1103 to rotate, and the second gear 1103 then drives the remaining second gears 1103 to rotate, so that the second rotating rod 1102 can rotate. The first rotating rod 1101 and the second rotating rod 1102 drive the mixing tank 10 to rotate, preventing the phosphogypsum in the mixing tank from piling up and allowing it to fully mix with the water phase. This facilitates subsequent extrusion of the phosphogypsum into blocks. After the phosphogypsum is mixed, the second drive motor 1202 is activated to drive the threaded rod 1203 to rotate. The threaded rod 1203 causes the fixed plate 1205 to move left and right, moving it into the fixed groove 1201. This opens the opening at the bottom of the mixing tank 10, allowing the mixed phosphogypsum to be discharged from the mixing tank 10 for subsequent extrusion into blocks. This is the working principle of this phosphogypsum production waste recycling device.
