[0002] Heavy metal wastewater treatment is an important field of environmental protection and industrial pollution control. Its core goal is to remove or reduce heavy metal ions in wastewater to meet discharge standards or achieve resource recovery.

[0003] When treating heavy metal wastewater, chemical reagents and reagents for accelerating flocculation are added to the wastewater to form precipitates of metal ions. Existing devices are provided with stirring rods in the pool to rotate, thereby accelerating the fusion of metal ions and reagents in the wastewater. When the stirring rod rotates at a high speed in a single direction, vortices will appear in the wastewater, which easily causes the reagents to flow towards the center of the formed vortices, making it difficult for the reagents to diffuse horizontally in the wastewater, and easily resulting in a slow mixing of the reagents and heavy metals in the wastewater during subsequent treatment, affecting the treatment effect of heavy metals in the wastewater.

[0014] Furthermore, a treatment process of a heavy metal wastewater treatment device, the method includes the following steps: S1: Wastewater exchange: After starting the motor, the drive shaft and the chassis start to rotate driven by the motor. During the rotation, the vibration springs will generate irregular oscillating movements, thereby accelerating the uniform mixing of wastewater at different depths. And a flow splitting assembly is arranged on the outer side surfaces of the chassis and the annular plate. During the rotation, the wastewater close to the drive shaft can disperse the water flow through the grating, completing the mixing of the inner and outer side wastewater. S2: Lateral rotation: When the vibration springs drive the annular plate to vibrate up and down, the vertical rods can be driven to slide up and down, and then the stirring assembly is driven to rotate by the vertical rods, thereby regulating the rotation amplitude of the paddles. During the rotation, the changing paddles can stir the wastewater at a variable speed, realizing the lateral rotation of the wastewater. S3: Bottom-side mixing: During the rotation of the water flow, the vertical plate will start to rotate. When the driving spring starts to reset, it can drive the lever to move, and then the vertical plate continues to rotate. When the vertical plate rotates 270°, it can continue to rotate under the rotating water flow to reset, and finally achieve mixing of the bottom-side wastewater; S4: Elastic reset: When the vertical plate starts to rotate, due to the setting of the intercepting plate, the vertical plate will be dragged downward under the action of the water flow. Under the action of the limit plate and the piston rod, the waste water can be introduced into the absorption box. After the vertical plate rotates 180°, the vertical plate can be reset under the action of the tension spring. At this time, the absorption box will drain outward. At this time, the connecting hole can also be cleaned under the action of the dredging sleeve and the curved spring to avoid blockage.

[0015] The present invention has the following beneficial effects: 1. The present invention starts the motor to drive the transmission shaft and the chassis to rotate, thereby causing the device to start rotating as a whole. During the rotation process, the wastewater inside and outside the main body can be replaced by the diversion component, and the wastewater in the middle part can be exchanged by the oscillation component. The device starts to change the speed angle horizontally through the stirring component, so that the wastewater inside and outside can be replaced faster, thereby strengthening the synchronous fusion of wastewater and reagents in the horizontal and vertical directions, thereby accelerating the mixing rate of metal ions in the reagents and wastewater, and strengthening the precipitation and flocculation effect of heavy metal ions.

[0016] 2. In the present invention, during the rotation process, the water flow will also follow the rotation, thereby driving the vertical plate to rotate. When the vertical plate starts to rotate, the rotating component will strengthen the rotation effect of the vertical plate, thereby allowing the vertical plate to complete a rotation cycle. When the vertical plate rotates, it will also drive the absorption box to complete a water absorption and drainage operation, thereby strengthening the longitudinal exchange effect of wastewater at different depths on the bottom edge, allowing the reagent and metal ions to fuse more fully, thereby accelerating the precipitation rate of metal ions.

[0017] 3. In the present invention, when the absorption box absorbs water, the wastewater flowing into the adapter box will drive the flat plate to rotate, so that the flat plate is stuck in the adapter box, and the wastewater will be transmitted to the adapter box through the unblocking sleeve. In this process, excessive impurities can be prevented from entering the absorption box. When the absorption box is draining, the outflowing wastewater can also drive the flat plate to rotate, so that the unblocking sleeve is inserted into the flow hole, thereby completing the unblocking of the flow hole and avoiding the blockage of the flow hole, thereby enhancing the effect of the absorption box on absorbing and discharging wastewater.

During the rotation of the flipping component 32, the suction and discharge component 33 can absorb and discharge the wastewater at different depths, thereby enhancing the overall mixing effect of the device.

[0027] The driving component 11 includes an upper mounting plate fixedly connected to the top surface of the main body 1. A motor 111 is fixedly connected to the top surface of the upper mounting plate. The output end of the motor 111 penetrates through the upper mounting plate and is fixedly connected to a transmission shaft 112. A vertical sliding groove is formed on the outer surface of the transmission shaft 112, and the lower end of the transmission shaft 112 is fixedly connected to a chassis 113; The flow splitting component 12 includes four U-shaped frames 121 arranged on the outer surface of the transmission shaft 112. A number of partitions 122 are rotatably connected inside the four U-shaped frames 121. When the motor 111 is started, the transmission shaft 112 can be driven to rotate by the motor 111. Since the transmission shaft 112 and the chassis 113 are fixedly connected, the chassis 113 can be driven to rotate synchronously. During the rotation process, the wastewater close to the transmission shaft 112 will surge outward. During the flow of the water, it will pass through the middle of the partitions 122, so that the water flow can be dispersed, and the reagent concentration on the inner and outer sides of the wastewater can be made more balanced.

[0028] The oscillation component 21 includes a vibration spring 212 fixedly connected to the top surface of the chassis 113.

A connecting rod is fixedly connected to the inner side surface of the annular plate 211. The connecting rod is slidably connected in the vertical sliding groove. A number of telescopic rods 213 are hinged to the outer side surface of the chassis 113. The end of the telescopic rod 213 away from the chassis 113 is hinged to the outer side surface of the vibration spring 212. Since the vibration spring 212 is fixedly connected to the upper surface of the chassis 113, the vibration spring 212 can also be driven to start rotating. During the rotation process of the vibration spring 212, the vibration spring 212 will start to vibrate up and down, thereby accelerating the mixing of the wastewater in the middle part of the main body 1.

[0029] The stirring component 22 includes four vertical rods 221 fixedly connected to the bottom of the annular plate 211. The lower ends of the vertical rods 221 penetrate and are slidably connected inside the chassis 113. A tooth groove is formed on the side surface of the lower end of the vertical rod 221 away from the transmission shaft 112; Among them, four fixing frames are fixedly connected to the bottom of the chassis 113.

A dial 223 is fixedly connected to the side surface of the transmission gear 222 away from the vertical rod 221. During the sliding process of the vertical rod 221, since the transmission gear 222 and the tooth groove are meshed with each other, the transmission gear 222 can be driven to start rotating irregularly, thereby realizing the rotation of the dial 223. During the rotation process, the angle of the dial 223 changes, so that the wastewater in the main body 1 can be stirred at a variable speed during the horizontal stirring, thereby strengthening the fusion between the wastewater and the reagent and achieving a better mixing effect.

[0030] The elastic member includes a second baffle 317 disposed on the front side of the chassis 113. A driving spring 316 is fixedly connected to the bottom of the second baffle 317.

The rotating assembly 31 includes two fixing plates 311 fixedly connected to the side surface of the chassis 113. A rotating box 312 is fixedly connected to the side surface of the fixing plate 311 away from the chassis 113. The second baffle 317 is fixedly connected to the inner side wall of the rotating box 312 close to the fixing plate 311. Among them, an inner groove is formed on the side surface of the rotating box 312 away from the fixing plate 311. Two limiting springs are fixedly connected to the top surface of the inner groove. One end of the two limiting springs close to the center of the rotating box 312 is fixedly connected to a stopper 313. Among them, an annular plate is rotatably connected to the inner side wall of the rotating box 312 close to the fixing plate 311. Two side plates are fixedly connected to the outer surface of the annular plate. A lever 314 is fixedly connected to the side surface of each of the two side plates away from the fixing plate 311. The first baffle 315 is fixedly connected to the side surface of the side plate away from the fixing plate 311. The flowing water will drive the vertical plate 322 to start rotating. Since the two levers 314 are installed on both sides of the vertical plate 322, the lever 314 can be driven to start rotating, and then the stopper 313 is pressed down into the inner groove. At this time, the first baffle 315 can approach the second baffle 317 under the drive of the driving spring 316, thereby accelerating the rotation of the vertical plate 322. When the elastic potential energy of the driving spring 316 is weakened to the minimum, the vertical plate 322 can also rotate more than 270° from the initial state. Then, under the continuous scouring of the water flow, the vertical plate 322 continues to rotate until it returns to the reset state. Thus, a rotation cycle is completed. During this process, the wastewater at different heights on the lower side can be replaced, thereby enhancing the mixing effect of the device.

[0031] The stamping part includes a suction box 323 disposed in front of the rotating box 312. A stamping plate is slidably connected in the suction box 323. A plurality of piston rods 325 are fixedly connected to the top surface of the stamping plate. The top ends of the piston rods 325 penetrate through the top surface of the suction box 323. The flipping assembly 32 includes two rotating rods 321 rotatably connected to the side surface of the chassis 113. The rotating rods 321 penetrate through the rotating box 312. An internal groove is formed on the outer surface of the rotating rod 321. A vertical plate 322 is slidably connected in the internal groove. Among them, an intercepting plate is fixedly connected to the bottom of the vertical plate 322. A limiting plate 324 is fixedly connected to the outer side surface of the rotating rod 321. The suction box 323 is fixedly connected to the side surface of the vertical plate 322 close to the limiting plate 324. Among them, the top end of the piston rod 325 is fixedly connected to the bottom of the limit plate 324. The front side and the rear side of the intercepting plate are both fixedly connected with receiving plates. The top surfaces of the two receiving plates are both fixedly connected with tension springs 326. The ends of the tension springs 326 far from the receiving plates are fixedly connected with collars. The collars are rotatably connected to the outer side surface of the rotating rod 321. A plurality of communication holes are formed in the side surface of the vertical plate 322 close to the absorption tank 323. During the rotation of the vertical plate 322, the water flow will have an impact resistance on the intercepting plate, thereby causing the vertical plate 322 to slide downward in the built-in groove. During the downward sliding of the vertical plate 322, it will drive the absorption tank 323 away from the limit plate 324. Furthermore, the piston rod 325 will drive the punching plate to move, so that a negative pressure environment is generated inside the absorption tank 323, and the wastewater outside can be sucked into its interior through the communication holes and the transfer box 331. When the vertical plate 322 rotates 180°, the resistance received by the intercepting plate will decrease. Under the action of the tension spring 326, the vertical plate 322 will reset again, and the wastewater inside the absorption tank 323 can be punched out again, thereby enhancing the ability of wastewater replacement; The suction and discharge assembly 33 includes a transfer box 331 fixedly connected to the side of the vertical plate 322 away from the absorption tank 323. The transfer box 331 and the absorption tank 323 are communicated. The transfer box 331 and a plurality of communication holes are communicated.

The end of the curved spring 334 far from the inner side surface of the dredging sleeve 333 is fixedly connected with an elastic ball. The elastic ball is installed at the central position of the dredging sleeve 333. A flat plate is rotatably connected to the opening end of the absorption tank 323 close to the communication holes. A plurality of dredging sleeves 333 are communicated on the side surface of the flat plate. When the wastewater in the absorption tank 323 is flushed out, the flat plate can send the dredging sleeves 333 into the communication holes, and a part of the flocculent impurities adhering to the inner wall of the communication holes can be extruded. Moreover, the flushed wastewater can also wash the elastic ball outward, thereby driving the curved spring 334 to move in the communication holes, and further removing the excess impurities, so as to avoid the blockage of the communication holes.

[0032] A treatment process of a heavy metal wastewater treatment device, the method comprising the following steps: S1: Wastewater exchange: After starting the motor 111, the drive shaft 112 and the chassis 113 start to rotate driven by the motor 111. During the rotation, the vibration spring 212 will generate irregular oscillating motion, thereby accelerating the uniform mixing of wastewater at different depths. Moreover, a flow splitting assembly 12 is arranged on the outer side surfaces of the chassis 113 and the annular plate 211. During the rotation, the wastewater close to the drive shaft 112 can disperse the water flow through the grille 122 to complete the mixing of the inner and outer side wastewater; S2: Horizontal rotation: When the vibration spring 212 drives the annular plate 211 to vibrate up and down, the vertical rod 221 can also be driven to slide up and down, and then the vertical rod 221 drives the stirring assembly 22 to rotate, thereby adjusting the rotation amplitude of the paddle 223. During the rotation process, the changing paddle 223 can stir the wastewater at a variable speed to achieve lateral rotation of the wastewater; S3: Bottom side mixing: During the rotation of the water flow, the vertical plate 322 will be driven to start rotating. When the driving spring 316 starts to reset, it can drive the lever 314 to move, and then the vertical plate 322 will continue to rotate. After the vertical plate 322 rotates 270°, it can continue to rotate under the rotating water flow to reset, and finally achieve mixing of the bottom side wastewater; S4: Elastic reset: When the vertical plate 322 starts to rotate, due to the setting of the intercepting plate, the vertical plate 322 will be dragged downward under the action of the water flow. Under the action of the limit plate 324 and the piston rod 325, the waste water can be introduced into the absorption box 323. After the vertical plate 322 rotates 180°, under the action of the tension spring 326, the vertical plate 322 can be reset. At this time, the absorption box 323 will drain water outward. At this time, the connecting hole can also be cleaned under the action of the clearing sleeve 333 and the curved spring 334 to avoid blockage.

[0033] When in use, the motor 111 is started first, and the motor 111 can drive the transmission shaft 112 to rotate. Since the transmission shaft 112 and the chassis 113 are fixedly connected, the chassis 113 can be driven to rotate synchronously. Since the vibration spring 212 is fixedly connected to the upper surface of the chassis 113, the vibration spring 212 can also be driven to start rotating. During the rotation of the vibration spring 212, the vibration spring 212 will start to vibrate up and down, thereby accelerating the mixing of the wastewater in the middle end of the main body 1. The vibration spring 212 and the annular plate 211 are connected to each other, which can drive the annular plate 211 to vibrate up and down, thereby driving the vertical rod 221 fixedly connected to its bottom to slide up and down. During the sliding process of the vertical rod 221, since the transmission gear 222 and the tooth groove are meshed with each other, the transmission gear 222 can be driven to start irregular rotation, thereby realizing the rotation of the paddle 223. During the rotation process, the angle change of the paddle 223 can make the wastewater in the main body 1 realize variable speed stirring in the horizontal stirring, thereby strengthening the fusion between the wastewater and the reagent, so that there is a better mixing effect. The outer surfaces of the annular plate 211 and the bottom plate 113 are both provided with a flow dividing assembly 12. During the rotation process, the wastewater near the transmission shaft 112 will surge outwards. During the surge of the water flow, the water flow will pass through the middle of the grille 122, so that the water flow can be dispersed and the reagent concentration inside and outside the wastewater can be more balanced. During the horizontal rotation process, the water flow will also rotate accordingly. Since the pressure of the lower-layer wastewater is higher than that of the upper-layer wastewater, the rotating water flow will push the vertical plate 322 to start rotating. Since the two lever rods 314 are installed on both sides of the vertical plate 322, the lever rods 314 can be driven to start rotating, and then the stopper 313 is pressed down into the inner groove. At this time, the first baffle 315 can be driven by the driving spring 316 to approach the second baffle 317, thereby accelerating the rotation of the vertical plate 322. When the elastic potential energy of the driving spring 316 is weakened to the minimum, the vertical plate 322 can also rotate more than 270° from the initial state. Then, under the continuous scouring of the water flow, the vertical plate 322 continues to rotate until it returns to the reset state. Thus, a rotation cycle is completed. During this process, the wastewater at different heights on the lower side can be replaced, thereby enhancing the mixing effect of the device; During the rotation of the vertical plate 322, the water flow will have an impact resistance on the intercepting plate, causing the vertical plate 322 to slide downward in the built-in groove. During the downward sliding process of the vertical plate 322, the absorption box 323 will be driven away from the limiting plate 324. Then, the piston rod 325 will drive the stamping plate to move, creating a negative pressure environment inside the absorption box 323. The wastewater outside can be sucked into its interior through the communication hole and the adapter box 331. When the vertical plate 322 rotates 180°, the resistance received by the intercepting plate will decrease. Under the action of the tension spring 326, the vertical plate 322 will reset, and the wastewater inside the absorption box 323 can be re-pressed out, thereby enhancing the wastewater replacement ability; A flat plate is rotatably connected inside the opening end of the absorption box 323 close to the communication hole. A plurality of dredging sleeves 333 are communicated on the side surface of the flat plate. When the wastewater inside the absorption box 323 is flushed out, the flat plate can send the dredging sleeves 333 into the communication hole, extruding a part of the flocculent impurities adhered to the inner wall of the communication hole. Moreover, the flushing wastewater can also wash the elastic ball outward, driving the curved spring 334 to move inside the communication hole, thereby removing the excess impurities and avoiding the blockage of the communication hole.

8. A process for a heavy metal wastewater treatment device, characterized in that: Using the heavy metal wastewater treatment device as claimed in claim 7, the process comprises the following steps: S1: wastewater exchange: after the motor (111) is started, the motor (111) drives the transmission shaft (112) and the chassis (113) to start rotating. During the rotation process, the vibration spring (212) generates irregular oscillating motion, thereby accelerating the uniform mixing of wastewater at different depths. A flow diversion component (12) is provided on the outer side of the chassis (113) and the annular plate (211). During the rotation process, wastewater close to the transmission shaft (112) can disperse the water flow through the grille (122), thereby completing the mixing of the wastewater inside and outside. S2: lateral rotation: when the vibration spring (212) drives the annular plate (211) to vibrate up and down, the vertical rod (221) can also be driven to slide up and down, and then the vertical rod (221) drives the stirring assembly (22) to rotate, thereby adjusting the rotation amplitude of the paddle (223). During the rotation process, the changing paddle (223) can stir the wastewater at a variable speed, thereby realizing lateral rotation of the wastewater; S3: Bottom side mixing: During the rotation of the water flow, the vertical plate (322) is driven to start rotating. When the driving spring (316) starts to reset, the lever (314) is driven to move, thereby driving the vertical plate (322) to continue rotating. After the vertical plate (322) rotates 270°, it can continue to rotate under the rotating water flow to reset, thereby finally achieving mixing of the wastewater on the bottom side. S4: Elastic reset: When the vertical plate (322) starts to rotate, due to the setting of the intercepting plate, the vertical plate (322) will be dragged downward under the action of the water flow. Under the action of the limit plate (324) and the piston rod (325), the wastewater can be introduced into the absorption box (323). After the vertical plate (322) rotates 180°, under the action of the tension spring (326), the vertical plate (322) can be reset. At this time, the absorption box (323) will drain water outward. At this time, the communication hole can also be cleaned under the action of the dredging sleeve (333) and the curved spring (334) to avoid blockage.
