Description

[0002] Thallium is a toxic element, and thallium and its compounds are harmful to both humans and the environment. Thallium ions can enter the human body through the food chain and accumulate, leading to serious health problems. Long-term exposure to or ingestion of thallium may cause damage to the nervous system, kidneys, and digestive system. Appropriate safety measures and waste treatment methods must be taken when treating wastewater, exhaust gas, or solid waste containing thallium to prevent harm to the environment and human health.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] 1. Through the design of the mixing and heating mechanisms, the motor drives the stirring blades to rotate around the shaft while simultaneously rotating on their own axis. This generates a more complex fluid motion pattern, which helps to break the laminar flow state in the wastewater, promotes thorough mixing between the flocculant and the wastewater, and allows for a more uniform distribution of the flocculant in the wastewater. This ensures that the wastewater in each area can effectively contact the flocculant, thereby improving mixing efficiency. It also helps to enhance the shear force and turbulence intensity in the wastewater, causing suspended particles and colloidal substances in the wastewater to aggregate more quickly, forming larger flocs, thus improving the purification effect of the wastewater. As the stirring blades rotate, they continuously rub against the friction plate, generating heat and raising the temperature of the wastewater. The steam generator sprays high-temperature steam and transfers the heat to the wastewater, which accelerates the movement speed of molecules and increases the collision frequency, thereby improving the reaction rate.

[0029] 2. Through the setting of the conveying mechanism, before the wastewater is poured into the treatment tank, the motor drives the scraper to rotate and clean up the larger debris filtered off the filter plate. This can quickly remove suspended solids, particulate matter and other impurities in the wastewater, thereby reducing the burden on subsequent treatment stages. The continuous cleaning by the scraper ensures that the filter plate continues to work effectively and will not be blocked due to the accumulation of debris. Attached Figure Description

[0037] Example 1

[0038] like Figures 1-5 As shown, the thallium-containing wastewater treatment device proposed in this utility model includes a treatment tank 1, a support frame 5 disposed at the bottom of the treatment tank 1, a mixing mechanism, a heating mechanism, a partition plate 205, and a spiral blade 304.

[0039] The mixing mechanism is located inside the treatment tank 1, and it fully mixes the thallium-containing wastewater and flocculant through various forms of stirring.

[0040] The heating mechanism is located outside the mixing mechanism and is used to generate high-temperature steam to heat the wastewater;

[0041] The partition plate 205 is disposed inside the treatment box 1 to separate the mixing mechanism and the heating mechanism. The partition plate 205 is a heat-conducting material. The inside of the partition plate 205 is used to hold wastewater. The annular space formed by the partition plate 205 and the treatment box 1 is used to introduce high-temperature steam and transfer the heat of the high-temperature gas to the wastewater inside the partition plate 205.

[0042] The spiral blade 304 is mounted on the mixing mechanism to transport the wastewater from the bottom to the top. The spiral blade 304 works in conjunction with the heating mechanism to continuously replace the surface liquid of the wastewater.

[0043] The mixing mechanism includes a stirring component and a heating component; the stirring component is located inside the treatment tank 1 and stirs the wastewater through the combined operation of revolution and rotation; the heating component is located on the stirring component and is used to generate heat through friction under the drive of the stirring component. The stirring assembly includes a motor 301, a fixed frame 302, a rotating shaft 303, and a gear ring 307. The fixed frame 302 is located on the top of the processing tank 1. The motor 301 is located inside the fixed frame 302. The rotating shaft 303 is located at the output end of the motor 301. The outer side of the rotating shaft 303 is connected to the inner side of the spiral blade 304. A rotating disk 305 is located at the bottom of the rotating shaft 303. A fixing ring 306 is located on the outer side of the rotating disk 305. The outer side of the fixing ring 306 is connected to the inner side of the partition plate 205. The gear ring 307 is rotatably mounted on the bottom of the rotating disk 305, and the bottom of the gear ring 307 is connected to the inner bottom of the processing tank 1. A spur gear 308 meshes with the outer side of the gear ring 307. Four spur gears 308 are arranged in a ring around the gear ring 307. A connecting shaft 309 is provided at the top of the spur gear 308, and an agitator blade 310 is provided on the outer side of the connecting shaft 309. When the motor 301 is started, the motor 301 drives the rotating shaft 303 to rotate, and the rotating shaft 303 drives the rotating disk 305 to rotate on the fixed ring 306. Thus, the spur gear 308 and the agitator blade 310 are driven to rotate through the connecting shaft 309. At the same time, since the position of the gear ring 307 is fixed, the spur gear 308 rotates on its own axis while rotating around the gear ring 307, so that the agitator blade 310 rotates on its own axis along with the connecting shaft 309. This allows the agitator blade 310 to rotate on its own axis while rotating around the rotating shaft 303. Meanwhile, the rotating shaft 303 drives the spiral blade 304 to rotate, and the spiral blade 304 continuously transports the wastewater from the bottom to the top when it rotates. The heating assembly includes a pressing plate 311, a fixing plate 312, and a friction plate 313. The pressing plate 311 is located at the end of the stirring blade 310, and there are two pressing plates 311 symmetrically arranged about the stirring blade 310. The fixing plate 312 is located inside the partition plate 205. A telescopic tube 314 is provided on the side of the fixing plate 312 away from the partition plate 205, and a spring 315 is provided on the outside of the telescopic tube 314. The friction plate 313 is located at the end of the telescopic tube 314 away from the fixing plate 312. When the stirring blade 310 rotates, it drives the pressing plate 311 to rotate. The friction plate 313 has an overlapping part on the movement trajectory of the pressing plate 311. Both sides of the friction plate 313 are set as inclined surfaces to facilitate cutting into the friction plate 313. When the pressing plate 311 rotates to the vicinity of the friction plate 313, it will squeeze the friction plate 313. At this time, the spring 315 and the telescopic tube 314 generate a force to increase the friction between the friction plate 313 and the pressing plate 311, thereby enhancing the heat generation efficiency.

[0044] Example 2

[0045] like Figures 1-2 As shown, this utility model proposes a thallium-containing wastewater treatment device. Compared with Embodiment 1, this embodiment details the structure of the heating mechanism.

[0046] The heating mechanism includes a connecting frame 203, a steam generator 201, and a connecting pipe 202. The connecting pipe 202 is located at the bottom of the processing tank 1, and the steam generator 201 is located at the bottom of the connecting pipe 202. The bottom of the steam generator 201 is connected to the support frame 5. The connecting frame 203 is located on the outside of the rotating shaft 303. A stirring plate 204 is provided at the end of the connecting frame 203 away from the rotating shaft 303. Three stirring plates 204 are arranged to rotate around the rotating shaft 303. Three stirring plates 204 are arranged in a ring around the partition plate 205. Multiple filter holes are provided on the stirring plate 204. The filter holes can ensure the passage of water vapor. The rotating shaft 303 drives the connecting frame 203 to rotate, and the connecting frame 203 drives the stirring plate 204 to rotate, thereby mixing the high-temperature steam evenly through the stirring plate 204.

[0047] Example 3

[0048] like Figures 5-6 As shown, this utility model proposes a thallium-containing wastewater treatment device. Compared with Embodiment 1 and Embodiment 2, this embodiment details the structure of the conveying mechanism.

[0049] The conveying mechanism includes an inlet assembly and a pumping assembly. The inlet assembly is located at the top of the treatment tank 1 and is used to input the waste liquid to be treated into the treatment tank 1. The pumping assembly is located inside the treatment tank 1 and is used to pump the treated waste liquid to the next device. The pumping assembly includes a pumping pipe 409, a connecting box 410, and an outlet pipe 411. The connecting box 410 is located at the top of the treatment tank 1, and the pumping pipe 409 is located at the bottom of the connecting box 410. Two pumping pipes 409 are arranged in a ring around the connecting box 410. The outlet pipe 411 is located on the side of the connecting box 410. The end of the outlet pipe 411 away from the connecting box 410 is connected to the pump, so that water is pumped out through the pumping pipe 409 and sent to the subsequent treatment tank through the outlet pipe 411. The inlet assembly includes a second rotating shaft 401, a second spur gear 402, and a second conveying pipe 408. The second conveying pipe 408 is located at the top of the treatment tank 1. An annular groove is located at the top of the second conveying pipe 408, and a filter plate 407 is located inside the second conveying pipe 408. The filter plate 407 can filter out larger impurities in the wastewater, thus reducing the difficulty of subsequent flocculation treatment. The second rotating shaft 401 is located at the top of the motor 301, and the second spur gear 402 is located at the top of the second rotating shaft 401. A third spur gear 403 meshes with the side of the second spur gear 402. A first conveying pipe 404 is located inside the third spur gear 403, and an annular locking block is located at the bottom of the first conveying pipe 404. The annular locking block and the annular groove can be connected to the material. The annular locking block can slide within the annular slot. A connecting block 405 is provided on the inner side of the first conveying pipe 404, and a scraper 406 is provided on the side of the connecting block 405. After the first conveying pipe 404 and the second conveying pipe 408 are connected together, the top of the scraper 406 fits perfectly with the top of the filter plate 407. The motor 301 drives the second rotating shaft 401 to rotate, the second rotating shaft 401 drives the second spur gear 402 to rotate, the second spur gear 402 drives the third spur gear 403 to rotate, and the third spur gear 403 drives the first conveying pipe 404 to rotate. The first conveying pipe 404 drives the scraper 406 to rotate through the connecting block 405. The position of the filter plate 407 remains unchanged, so the impurities filtered down on the filter plate 407 can be scraped off and piled up for easy cleaning.

[0050] In summary, when using this utility model, the first conveying pipe 404 is aligned with the second conveying pipe 408 and then pressed down to connect the first conveying pipe 404 and the second conveying pipe 408 together. Then, the thallium-containing wastewater is poured in from the top of the first conveying pipe 404. When the wastewater passes through the filter plate 407, the filter plate 407 filters out all the larger impurities in the wastewater and places them above the filter plate 407. At the same time, the motor 301 and the steam generator 201 are started. The motor 301 drives the second rotating shaft 401 to rotate, and the second rotating shaft 401 drives the second spur gear 402 to rotate. The second spur gear 402 drives the third spur gear 403 to rotate, which in turn drives the first conveying pipe 404 to rotate. The first conveying pipe 404, through the connecting block 405, drives the scraper 406 to rotate, scraping away the debris on the filter plate 407 and causing it to accumulate. The filtered wastewater enters the treatment tank 1. At this time, the motor 301 drives the first rotating shaft 303 to rotate, which in turn drives the rotating disk 305 to rotate on the fixed ring 306. This, in turn, drives the first spur gear 308 and the stirring blade 310 to rotate through the connecting shaft 309. When shaft 308 rotates around gear ring 307, it rotates on its own axis under the meshing of gear ring 307, causing stirring blade 310 to rotate on its own axis while rotating around shaft 303. The rotation of stirring blade 310 drives the extrusion plate 311 to rotate. When the extrusion plate 311 rotates to the vicinity of friction plate 313, it squeezes friction plate 313, thereby generating heat. Simultaneously, shaft 303 drives spiral blade 304 to rotate. As spiral blade 304 rotates, it continuously transports wastewater from the bottom to the top, and steam generator 201 generates high-temperature steam. Warm steam is blown into the treatment tank 1 through the connecting pipe 202. At this time, the rotating shaft 303 drives the stirring plate 204 to rotate through the connecting frame 203. The stirring plate 204 mixes the steam in the partition plate 205 and the partition of the treatment tank 1 evenly, thereby transferring heat to the thallium-containing wastewater through the partition plate 205. The wastewater is more likely to mix with the flocculant in the high temperature environment, thus achieving sedimentation. At the same time, the high temperature steam can be blown to the upper surface of the thallium-containing wastewater through the notch at the top of the partition plate 205, thereby heating the upper surface of the wastewater.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
