Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to a heavy metal wastewater treatment device and process. Background Art

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

[0003] When treating heavy metal wastewater, chemical reagents and reagents that accelerate flocculation are added to the wastewater to allow the metal ions to form precipitates. The existing device sets a stirring rod in the pool to rotate, thereby accelerating the fusion of metal ions and reagents in the wastewater. When the stirring rod rotates in a single direction at high speed, a vortex will appear in the wastewater, which will easily cause the reagent to flow to the center of the formed vortex, making it difficult for the reagent to diffuse laterally in the wastewater, which will easily lead to slow mixing of the reagent and the heavy metals in the wastewater during subsequent treatment, affecting the treatment effect of heavy metals in the wastewater.

The elastic ball is installed in the center position of the dredging sleeve.

[0033] Furthermore, a treatment process for a heavy metal wastewater treatment device comprises the following steps:

[0034] S1: Wastewater exchange: After the motor is started, the drive shaft and chassis start to rotate. During the rotation, the vibration spring will produce irregular oscillation motion, thereby accelerating the uniform mixing of wastewater at different depths. Diversion components are set on the outer side of the chassis and the annular plate. During the rotation, the wastewater close to the drive shaft can be dispersed through the grille to complete the mixing of the wastewater inside and outside;

[0035] S2: Horizontal rotation: When the vibration spring drives the annular plate to vibrate up and down, it can drive the vertical rod to slide up and down, and then the vertical rod drives the stirring assembly to rotate, thereby adjusting the rotation amplitude of the paddle. During the rotation process, the changing paddle can stir the wastewater at a variable speed, realizing the horizontal rotation of the wastewater;

[0036] 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 will continue to rotate. After 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;

[0037] 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.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention starts the motor to drive the transmission shaft and the chassis to rotate, thereby causing the entire device to start rotating. During the rotation process, the diversion component can replace the wastewater inside and outside the main body, and the oscillation component can exchange the wastewater in the middle part. The stirring component allows the device to start the lateral speed change angle, 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 the reagents and metal ions in the wastewater, and enhancing the precipitation and flocculation effect of heavy metal ions.

[0040] 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 enhance 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 at the bottom edge, making the fusion of reagents and metal ions more complete, thereby accelerating the precipitation rate of metal ions.

[0041] 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 dredging 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 dredging sleeve is inserted into the flow hole, thereby completing the dredging of the flow hole and avoiding blockage of the flow hole, thereby enhancing the effect of the absorption box on absorbing and discharging wastewater.

[0042] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Suction and discharge assembly 33; the suction and discharge assembly 33 is installed on the front side of the rotating assembly 31;

[0069] When the water flow rotates, the flip assembly 32 can be controlled to rotate, and then flipped with the cooperation of the rotating assembly 31. During the rotation of the flip assembly 32, the suction and discharge assembly 33 can absorb and discharge wastewater of different depths, thereby enhancing the overall mixing effect of the device.

[0070] The drive assembly 11 includes an upper frame plate fixedly connected to the top surface of the main body 1. The top surface of the upper frame plate is fixedly connected to a motor 111. The output end of the motor 111 passes through the upper frame plate and is fixedly connected to a transmission shaft 112. The outer surface of the transmission shaft 112 is provided with a vertical slide groove. The lower end of the transmission shaft 112 is fixedly connected to a chassis 113.

[0071] The diversion assembly 12 includes four circular frames 121 arranged on the outer surface of the transmission shaft 112. The interior of the four circular frames 121 is rotatably connected to a plurality of grilles 122. When the motor 111 is started, 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. During the rotation, the wastewater close to the transmission shaft 112 will surge outward. During the surge of the water flow, it 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.

[0072] The vibration assembly 21 includes a vibration spring 212 fixedly connected to the top surface of the chassis 113. The top of the vibration spring 212 away from the chassis 113 is fixedly connected to an annular plate 211.

[0073] Among them, the annular plate 211 is sleeved on the outer surface of the transmission shaft 112, the inner side of the annular plate 211 is fixedly connected to a connecting rod, the connecting rod is slidably connected to the vertical slide groove, and the outer side of the chassis 113 is hinged with several telescopic rods 213, and the end of the telescopic rod 213 away from the chassis 113 is hinged to the outer side of the vibration spring 212. Because the vibration spring 212 is fixedly connected to the upper surface of the chassis 113, it can also drive the vibration spring 212 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 part of the main body 1.

[0074] The stirring assembly 22 includes four vertical rods 221 fixedly connected to the bottom of the annular plate 211. The lower ends of the vertical rods 221 pass through and are slidably connected to the chassis 113. The lower ends of the vertical rods 221 are provided with tooth grooves on the side away from the transmission shaft 112.

[0075] The bottom of the chassis 113 is fixedly connected to four fixing frames, and the four fixing frames are rotatably connected to transmission gears 222. The transmission gear 222 is meshed and connected to the tooth groove. The transmission gear 222 is fixedly connected to the side away from the vertical rod 221 with a paddle 223. During the sliding process of the vertical rod 221, because 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 of the paddle 223 changes, which can make the wastewater in the main body 1 stir horizontally and achieve variable speed stirring, thereby enhancing the fusion between the wastewater and the reagent, so as to achieve a better mixing effect.

[0076] The elastic member includes a second baffle 317 provided on the front side of the chassis 113. The bottom of the second baffle 317 is fixedly connected to a driving spring 316. The end of the driving spring 316 away from the second baffle 317 is fixedly connected to the first baffle 315.

[0077] The rotating assembly 31 includes two fixed plates 311 fixedly connected to the sides of the chassis 113. The sides of the fixed plates 311 away from the chassis 113 are fixedly connected to the rotating box 312. The second baffle 317 is fixedly connected to the inner side wall of the rotating box 312 near the fixed plates 311.

[0078] The side of the rotating box 312 away from the fixed plate 311 is provided with an inner groove, the top surface of which is fixedly connected to two limit springs, and one end of the two limit springs close to the center of the rotating box 312 is fixedly connected to a stopper 313;

[0079] The rotating box 312 is rotatably connected to the inner side wall of the fixed plate 311, and the outer surface of the ring plate is fixedly connected to two side plates. The sides of the two side plates away from the fixed plate 311 are fixedly connected to the lever 314, and the first baffle 315 is fixedly connected to the side of the side plate away from the fixed plate 311. The rotating water flow will push the vertical plate 322 to start rotating. Because the two levers 314 are installed on both sides of the vertical plate 322, the lever 314 can be driven to start rotating, thereby pressing the stopper 313 down to In the inner tank, at this time, the No. 1 baffle 315 can be driven by the driving spring 316 to move closer to the No. 2 baffle 317, thereby accelerating the rotation of the vertical plate 322. When the elastic potential energy of the driving spring 316 is reduced to a minimum, the vertical plate 322 can also rotate more than 270° from the initial state. Then, under the continued flushing of the water flow, the vertical plate 322 continues to rotate until it is reset, thus completing a rotation cycle. During this process, the wastewater at different heights on the lower side can be replaced, thereby enhancing the mixing effect of the device.

[0080] The stamping part includes an absorbing box 323 provided on the front side of the rotating box 312. A stamping plate is slidably connected to the inside of the absorbing 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 pass through the top surface of the absorbing box 323.

[0081] The flip assembly 32 includes two rotating rods 321 rotatably connected to the side of the chassis 113. The rotating rods 321 pass through the rotating box 312. The outer surface of the rotating rods 321 is provided with a built-in groove, and the vertical plate 322 is slidably connected to the built-in groove.

[0082] The bottom of the vertical plate 322 is fixedly connected to the intercepting plate, the outer side of the rotating rod 321 is fixedly connected to the limiting plate 324, and the absorbing box 323 is fixedly connected to the side of the vertical plate 322 close to the limiting plate 324;

[0083] The top of the piston rod 325 is fixedly connected to the bottom of the limit plate 324, and the front and rear sides of the intercepting plate are fixedly connected to the receiving plate. The top surfaces of the two receiving plates are fixedly connected to the tension spring 326. The end of the tension spring 326 away from the receiving plate is fixedly connected to the ring. The ring is rotatably connected to the outer side of the rotating rod 321. The side of the vertical plate 322 close to the absorption box 323 is provided with a number of connecting holes. 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 move in the built-in groove. When the vertical plate 322 slides downward, it will drive the absorption box 323 away from the limit plate 324, and then the piston rod 325 will drive the punching plate to move, so that a negative pressure environment is generated in the absorption box 323, and the waste water outside can be sucked into it through the connecting hole and the adapter box 331. When the vertical plate 322 rotates 180 degrees, the resistance to the interception plate will be reduced. Under the action of the tension spring 326, the vertical plate 322 will be reset, and the waste water inside the absorption box 323 can be punched out again, thereby enhancing the waste water replacement capacity;

[0084] The suction and discharge assembly 33 includes an adapter box 331 fixedly connected to the side of the vertical plate 322 away from the suction box 323. The adapter box 331 and the suction box 323 are connected. The adapter box 331 and the plurality of communication holes are connected. A rotating shaft 332 is rotatably connected between the top surface and the inner bottom of the opening groove of the adapter box 331 near the communication hole.

[0085] Among them, a flat plate is fixedly connected to the outer side of the rotating shaft 332, and several dredging sleeves 333 are fixedly connected to the side of the flat plate near the communicating hole. Several dredging sleeves 333 are fixedly connected to the inside of each dredging sleeve 333. The end of the curved spring 334 away from the inner side of the dredging sleeve 333 is fixedly connected to an elastic ball, and the elastic ball is installed at the center position of the dredging sleeve 333. A flat plate is rotatably connected to the open end of the absorption box 323 near the communicating hole, and several dredging sleeves 333 are connected to the side of the flat plate. When the wastewater in the absorption box 323 is flushed out, the flat plate can send the dredging sleeve 333 into the communicating hole, which can squeeze out a part of the flocculent impurities adhered to the inner wall of the communicating hole, and the flushed wastewater can also flush the elastic ball outward, thereby driving the curved spring 334 to move in the communicating hole, thereby removing excess impurities and avoiding blockage of the communicating hole.

[0086] A treatment process for a heavy metal wastewater treatment device, the method comprising the following steps:

[0087] S1: Wastewater exchange: After starting the motor 111, the drive shaft 112 and the chassis 113 start to rotate. During the rotation, the vibration spring 212 will produce irregular oscillation motion, thereby accelerating the uniform mixing of wastewater at different depths. A diversion component 12 is provided on the outer side of the chassis 113 and the annular plate 211. During the rotation, the wastewater close to the drive shaft 112 can be dispersed through the grille 122 to complete the mixing of the wastewater inside and outside;

[0088] S2: Horizontal rotation: When the vibration spring 212 drives the annular plate 211 to vibrate up and down, it can drive the vertical rod 221 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 achieving horizontal rotation of the wastewater;

[0089] S3: Bottom-side mixing: During the water flow rotation, the vertical plate 322 will start to rotate. 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 degrees, it can continue to rotate under the rotating water flow to reset, and finally achieve bottom-side wastewater mixing;

[0090] 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°, the vertical plate 322 can be reset under the action of the tension spring 326. 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.

[0091] When in use, first start the motor 111, which can drive the transmission shaft 112 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. 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, because the transmission gear 222 and the tooth groove are engaged 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 of the paddle 223 changes, which can make the wastewater in the main body 1 stir horizontally, realize variable speed stirring, thereby strengthening the fusion between the wastewater and the reagent, so as to achieve a better mixing effect.

[0092] A flow diversion assembly 12 is provided on the outer surface of the annular plate 211 and the bottom plate 113. During the rotation process, the wastewater near the transmission shaft 112 will surge outwards. During the surge of the water flow, it will pass through the middle of the grille 122, so that the water flow is dispersed and the concentration of the reagent inside and outside the wastewater is more balanced.

[0093] During the lateral rotation, the water flow will also rotate with it. Since the pressure of the wastewater in the lower layer is higher than that in the upper layer, the rotating water flow will push 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, thereby pressing the stopper 313 down into the inner groove. At this time, the first baffle 315 can be driven by the driving spring 316 to move closer to the second baffle 317, thereby accelerating the rotation of the vertical plate 322. When the elastic potential energy of the driving spring 316 is reduced to a minimum, the vertical plate 322 can also rotate more than 270° from the initial state. Then, under the continued flushing of the water flow, the vertical plate 322 continues to rotate until it returns to the reset state, thus completing a rotation cycle. In this process, the wastewater at different heights on the lower side can be replaced, thereby enhancing the mixing effect of the device.

[0094] When the vertical plate 322 rotates, 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. When the vertical plate 322 slides downward, it will drive the absorption box 323 away from the limit plate 324, and then the piston rod 325 will drive the stamping plate to move, so that a negative pressure environment is generated in the absorption box 323, and the waste water outside can be sucked into it through the connecting hole and the adapter box 331. When the vertical plate 322 rotates 180 degrees, the resistance to the intercepting plate will be reduced. Under the action of the tension spring 326, the vertical plate 322 will be reset, and the waste water inside the absorption box 323 can be punched out again, thereby enhancing the wastewater replacement capacity.

[0095] A flat plate is rotatably connected to the open end of the absorption box 323 near the communicating hole, and a number of dredging sleeves 333 are connected to the side of the flat plate. When the waste water in the absorption box 323 is flushed out, the flat plate can send the dredging sleeves 333 into the communicating hole, which can squeeze out some of the flocculent impurities adhering to the inner wall of the communicating hole. The flushing waste water can also flush the elastic ball outward, thereby driving the curved spring 334 to move in the communicating hole, thereby removing excess impurities and avoiding blockage of the communicating hole.
