[0002] Phosphogypsum is the residue of phosphate rock after phosphoric acid production and belongs to acidic substances. The main components are calcium sulfate (CaSO 4 ), attached water (H 2 O), water-soluble phosphorus pentoxide (P 2 O 5 ), water-soluble fluoride ion (F - ), water-soluble magnesium oxide (MgO), heavy metals, etc. Before modification, phosphogypsum was classified as Class II general industrial solid waste and could not be utilized as a resource.

[0003] According to the current regulations, after modification, phosphogypsum meets the relevant requirements of Class I general industrial solid waste specified in the "Pollution Control Standards for Storage and Landfill of General Industrial Solid Wastes" (GB18599-2020), and meets the screening value standard for the second type of land use in the "Soil Environmental Quality Risk Control Standards for Soil Pollution of Construction Land (Trial)" (GB36600-2018), and can be comprehensively utilized as an industrial product.

[0004] The modification of phosphogypsum mainly takes the compliance of pollution characteristic values such as pH, water-soluble phosphorus, water-soluble fluorine, and heavy metals as the main basis for meeting the requirements of Class I general industrial solid waste.

It is hereby declared that the upper, lower, left, right, front, rear, inner, outer and other orientation terms that appear or will appear in the present invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0040] Example 1

[0041] As Figure 3 - Figure 15As shown in the figure, a phosphogypsum on-line monitoring system includes a device main body 1, a phosphogypsum quantifier 2, a deionized water quantifier 3, a manipulator 4, an operation console 5, an ultrapure water machine 6, a horizontal oscillator 7, an automatic suction filter 8, a water sample distributor 9, and an eigenvalue detector 10. Inside the device main body 1, there is a phosphogypsum quantifier 2. The device main body 1 is equipped with a system feed inlet 101, a temperature and humidity regulator 102, a video monitoring system, an access control system, a lighting system, an automatic control system, and a data collector. The phosphogypsum quantifier 2 is connected to the system feed inlet 101 through a pipeline. On one side of the phosphogypsum quantifier 2, there is a deionized water quantifier 3. The operation console 5 is located inside the device main body 1. On the lower surface inside the device main body, there is a fixed manipulator 4. On one side of the operation console 5, there is an ultrapure water machine 6. On one side of the ultrapure water machine 6, there is a horizontal oscillator 7. On the side of the horizontal oscillator 7 away from the ultrapure water machine 6, there is an automatic suction filter 8. On the side of the automatic suction filter 8 away from the horizontal oscillator 7, there is a water sample distributor 9. The device main body 1 is a laboratory.

[0042] As Figure 5 shown in the figure, the phosphogypsum quantifier 2 consists of a flexible hose 201, a primary storage tank 202, a first electric valve 203, a quantitative feeding belt 204, a secondary quantitative tank 205, a second electric valve 206, a quantitative tank weighing sensor 207, a fixed bracket 208, and a storage tank weighing sensor 209. The flexible hose 201 is connected to the system feed inlet 101. At the other end of the flexible hose 201, there is a primary storage tank 202. Below the primary storage tank 202, there is a first electric valve 203. Below the first electric valve 203, there is a quantitative feeding belt 204. At the discharge port of the quantitative feeding belt 204, there is a secondary quantitative tank 205. At the lower discharge port of the secondary quantitative tank 205, there is a second electric valve 206. The fixed bracket 208 is located on the side of the quantitative feeding belt 204 for connecting the phosphogypsum quantifier 2 to the device main body 1. The primary storage tank 202 is equipped with a storage tank weighing sensor 209, and the secondary quantitative tank 205 is equipped with a quantitative tank weighing sensor 207.

[0043] The phosphogypsum first enters the primary storage tank 202, and the weight is measured by the storage tank weighing sensor 209. The first electric valve 203 is opened, and the phosphogypsum is metered according to the weight loss algorithm and falls onto the quantitative feeding belt 204. The phosphogypsum is transported by the quantitative feeding belt 204 to the secondary quantitative tank 205, and the secondary quantitative tank 205 accurately measures by the weight gain method. After the phosphogypsum in the secondary quantitative tank 205 reaches the preset phosphogypsum quality, the first electric valve 203 is closed, and the quantitative feeding belt 204 is stopped. After the manipulator 4 places the extraction bottle at the designated position below the discharge port, the second electric valve 206 is opened, and the metered phosphogypsum is loaded into the extraction bottle. Then, the manipulator 4 places the extraction bottle filled with phosphogypsum at the designated position below the water outlet of the deionized water quantifier 3.

[0044] As shown Figure 6 As shown in the figure, the deionized water quantifier 3 is composed of a quantitative water tank 301, a third electric valve 302, a weighing sensor, a peristaltic tube 304, and a peristaltic pump 305. A third electric valve 302 is provided at the water outlet of the quantitative water tank 301. The quantitative water tank 301 is equipped with a quantitative water weighing sensor 303. A peristaltic tube 304 is provided between the peristaltic pump 305 and the quantitative water tank 301.

[0045] It should be noted that the peristaltic pump 305 quantitatively pumps the deionized water produced by the ultrapure water machine 6 into the quantitative water tank 301 through the peristaltic tube 304. The quantitative water tank 301 accurately measures by the weight gain method. After the quantitative water weighing sensor 303 measures that the deionized water in the quantitative water tank 301 reaches the set mass, the peristaltic pump 305 is turned off, and the third electric valve 302 is opened, and the quantitative deionized water flows into the extraction bottle containing phosphogypsum.

[0046] As shown Figure 7 - Figure 15 As shown in the figure, the manipulator 4 is composed of a fixed seat 401, a robotic arm 402, a tooling plate 403, clamping fingers 404, and a suction cup 405. The fixed seat 401 is fixedly connected to the lower surface inside the device main body 1. The robotic arm 402 is movably connected to the fixed seat 401. A tooling plate 403 is provided at one end of the movable arm away from the fixed seat 401. Clamping fingers 404 and a suction cup 405 are respectively provided on both sides of the tooling plate 403. The operation table 5 includes a box body 502. The upper surface of the box body 502 is provided with an extraction bottle main body 501. An installation box 504 is provided on one side of the box body 502. A hot air dryer 503 and a cleaning faucet 505 are provided inside the installation box 504. A placement rack 506 is provided on the side of the installation box 504 away from the box body 502. A cap storage magazine 507 is provided above the placement rack 506. A cap main body 508 is provided inside the cap storage magazine 507. An extraction bottle main body 501 is provided inside the placement rack 506. An extraction bottle fixing tooling 510 is provided on one side of the placement rack 506. An extraction bottle main body 501 is provided inside the extraction bottle fixing tooling 510. A cap fixing tooling 509 is provided below the cap storage magazine 507. The extraction bottle fixing tooling 510 includes a fixed chuck 5101, a movable chuck 5102, and a driving cylinder 5103. The movable chuck 5102 is fixed on the cylinder head of the driving cylinder 5103 and moves synchronously with the cylinder head.

[0047] It should be noted that the extraction bottle fixing tooling 510 is composed of a fixed chuck 5101, a movable chuck 5102, and a driving cylinder 5103. The movable chuck 5102 is fixed on the cylinder head of the driving cylinder 5103 and moves synchronously with the cylinder head. The movable chuck 5102 has two working positions. When in the clamping position, the fixed chuck 5101 and the movable chuck 5102 jointly clamp the extraction bottle.

[0048] After the manipulator 4 places the extraction bottle into the extraction bottle fixing tooling 510, it uses the suction cup 405 to pick up the inner cap from the inner cap storage magazine and press it onto the extraction bottle. Then, the manipulator 4 uses the suction cup 405 to grab the screw cap from the screw cap storage magazine and places the screw cap onto the screw cap fixing tooling 509. After the manipulator 4 replaces the clamping fingers 404, it clamps the screw cap, and the robotic arm 402 moves to screw the screw cap tightly onto the extraction bottle, completing the work of extracting the inner cap and the screw cap of the extraction bottle.

[0049] After the extraction bottle cap is tightened, the extraction bottle fixing tooling 510 resets to the loose state. The manipulator 4 places the extraction bottle into the horizontal oscillator 7 for horizontal oscillation. After the horizontal oscillation is completed, the manipulator 4 takes out the extraction bottle from the horizontal oscillator 7 and places it into the extraction bottle static rack. The extraction bottle static rack can be used as the static position after horizontal oscillation and also as the storage position for empty extraction bottles.

[0050] When the static time of the extraction bottle after horizontal oscillation arrives, the manipulator 4 places the extraction bottle into the extraction bottle fixing tooling 510. After the extraction bottle fixing tooling 510 clamps the extraction bottle, the manipulator 4 completes the work of unscrewing the screw cap and sucking away the inner cap. Both the screw cap and the inner cap are cleaned by the manipulator 4 in cooperation with the cleaning faucet 505 and the hot air dryer 503, and then put back into their respective magazines after cleaning.

[0051] As Figure 8 shown, the automatic suction filter 8 consists of an air shaft 801, a movable sealing head 802, a filter membrane roll 803, a winding and unwinding motor 804, a filter residue recovery box 805, a suction filter tank and a vacuum system. The filter membrane of the filter membrane roll 803 is a 0.45μm microporous filter membrane. The movable sealing head 802 is driven by a cylinder. The winding and unwinding motor 804 winds and unwinds the filter membrane roll 803 at a fixed length. The air shaft 801 is used to radially clamp the inner core of the filter membrane roll 803. The filter residue recovery box 805 is used to recover the filter residue filtered out after suction filtration.

[0052] It should be noted that the aforementioned extraction bottle is grabbed by the manipulator 4 above the suction filter port of the automatic suction filter 8. The filter membrane is a 0.45μm microporous filter membrane. The movable sealing head 802 is driven by a cylinder. The winding and unwinding motor 804 winds and unwinds the filter membrane roll 803 at a fixed length. Each time after suction filtration, a fixed length of clean filter membrane is released. Before winding and unwinding the filter membrane, the movable sealing head 802 opens to allow the filter membrane to pass through. After winding and unwinding the filter membrane is completed, the movable sealing head 802 closes, and the sealing ring on the sealing head presses the filter membrane tightly. The filter residue filtered out after the previous suction filtration is automatically poured into the filter residue recovery box 805 through winding and unwinding. The air shaft 801 is used to radially clamp the inner core of the filter membrane roll 803 to limit the non-working degrees of freedom of the filter membrane roll 803 during the working process.

[0053] The manipulator 4 pours the phosphogypsum and the leaching solution in the extraction bottle into the automatic suction filter 8. The automatic suction filter 8 filters out the leaching solution and pumps the leaching solution to the water sample dispenser 9. The water sample dispenser 9 distributes the leaching solution to each characteristic value detector 10 for characteristic value detection.

[0054] The manipulator 4 grips and extracts the bottle and cooperates with the cleaning faucet 505 and the hot air dryer 503 for cleaning, and then places the cleaned empty extraction bottle into the extraction bottle static rack.

[0055] The eigenvalue data detected by each eigenvalue detector 10, the corresponding sampling, the entire process video data of the test, and the data of the operation of each device are packaged together. After packaging, they are transmitted by the data acquisition instrument to the local data storage system and the cloud storage system. The cloud storage system classifies and transmits the data to each authorized terminal data receiving device in real time as needed.

[0056] The above-mentioned phosphogypsum quantizer 2, automatic suction filter 8, water sample dispenser 9, eigenvalue detector 10 and all working pipelines are all designed with self-cleaning functions.

[0057] When in use, as Figure 17 shown, a negative pressure suction sampling device is set at the discharge conveyor or the storage yard of the phosphogypsum modification production line to negatively and quantitatively suck the phosphogypsum to be inspected. The phosphogypsum to be inspected is pneumatically conveyed to the cyclone dryer, and after drying, it is pneumatically conveyed to the system feed port 101.
