Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment equipment and relates to a precise quantitative coagulation device for wastewater treatment. Background Technology

[0002] Water pollution control refers to the process of removing, transforming, and stabilizing pollutants in water bodies through various technical methods to restore or improve water quality. Water pollution control technologies mainly include wastewater treatment technology, wastewater reuse technology, source water protection technology, and water pollution monitoring and early warning technology. Currently, commonly used biological treatment technologies include activated sludge processes, biofilm processes, and aerated biological filters. In recent years, significant innovative achievements have been made in water pollution control technologies, and these technologies have been widely applied both domestically and internationally.

[0003] Coagulation is a core chemical technology in water treatment. By adding coagulants to water, the stability of colloidal particles is disrupted, causing them to adsorb with impurities in the water and agglomerate into larger flocs (floc). After settling and gravity, the flocs settle at the bottom, and finally, the clear water at the top is taken, thus achieving the effect of separating impurities in the water, which facilitates subsequent sedimentation or filtration to remove pollutants.

[0004] Currently, the commonly used method for wastewater coagulation treatment is the use of baffled plate coagulation tanks. Wastewater is continuously fed into a mixing device, where coagulant is continuously added during the mixing process. The wastewater then continuously enters the baffled plate flocculation zone from the mixing device, and finally enters the sedimentation separation zone for separation. While this continuous treatment method improves efficiency, the continuous flow of wastewater and coagulant necessitates precise control of both quantities. Too little coagulant will not achieve the desired coagulation effect, while too much will result in waste. Furthermore, the continuous flow of wastewater means that the mixing effect between wastewater and coagulant cannot be optimized. Therefore, we propose a precise quantitative coagulation device for wastewater treatment to address the aforementioned problems. Summary of the Invention

[0005] In view of this, in order to solve the problems that the delivery volume of sewage and coagulant is not easily controlled in the traditional coagulation process, and that the mixing effect between sewage and coagulant is not optimized, the present invention provides a precise quantitative coagulation device for sewage treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a mounting plate, wherein two support columns are symmetrically fixedly connected to the bottom of the mounting plate for supporting the installation of the entire mounting plate; The mixing seat is rotatably connected to one side of the mounting plate and is used to mix and stir the sewage with the coagulant to complete the coagulation of the sewage. A servo motor is fixedly installed on one side of the mounting plate, and the output shaft of the servo motor rotates through the mounting plate and is fixedly connected to one side of the mixing seat. It is used to drive the mixing seat to rotate back and forth for adjustment. By tilting the mixing seat, intermittent alternation between quantitative mixing of sewage and drainage can be achieved. Two storage tanks are symmetrically fixedly connected to the top two sides of the mixing base, and can automatically and quantitatively feed the coagulant as the mixing base rotates synchronously. The wastewater conveying mechanism is located between the two storage tanks and is used to convey the filtered wastewater to the mixing seat to complete the coagulation work.

[0007] Furthermore, the top two sides of the stirring base are symmetrically provided with a first stirring tank and a second stirring tank. The bottom walls of the first stirring tank and the second stirring tank are both inclined. The interior of the stirring base is provided with a bucket-shaped drainage cavity located between the first stirring tank and the second stirring tank. The first stirring tank and the bucket-shaped drainage cavity are connected by a first drainage port, and the second stirring tank and the bucket-shaped drainage cavity are connected by a second drainage port. The bottom of the stirring base is provided with a drainage pipe connected to the bucket-shaped drainage cavity.

[0008] Furthermore, both the first and second mixing tanks are horizontally rotatably connected to mixing shafts. The outer walls of both mixing shafts are provided with at least one set of mixing blades. The ends of both mixing shafts away from the mounting plate are sealed and rotatably pass through one side of the mixing seat and are fixedly fitted with driven pulleys. The top edge of the mixing seat away from the mounting plate is fixedly connected to a drive motor. The output shaft of the drive motor is fixedly fitted with a driving pulley. The driving pulley and the two driven pulleys are driven by the same synchronous belt.

[0009] Furthermore, two vertical plates are symmetrically fixedly connected to the top two sides of the mixing base, and two storage boxes are respectively fixedly connected to one side of the two vertical plates. The bottom of the two storage boxes is inclined. The top of the two storage boxes is fixedly provided with a feeding pipe for adding coagulant on the side close to each other, and the bottom of the two storage boxes is fixedly provided with a feeding pipe for dispensing coagulant on the side close to each other. The bottom ends of the two feeding pipes correspond to the first mixing tank and the second mixing tank, respectively. A set of quantitative components for controlling the corresponding feeding pipe to quantitatively dispense coagulant is provided on one side of the two vertical plates.

[0010] Furthermore, the quantitative component includes an L-shaped baffle plate that is slidably connected to the bottom of one side of the vertical plate, and the top side of the L-shaped baffle plate is sealed and fitted to the bottom end of the feeding pipe. The top side of the L-shaped baffle plate is provided with a feeding hole that is intermittently connected and cooperates with the feeding pipe.

[0011] Furthermore, a guide rod is slidably connected through one side of the L-shaped baffle plate, and one end of the guide rod is fixedly connected to one side of the vertical plate. A first return spring is sleeved on the outer wall of the guide rod, and the two ends of the first return spring are fixedly connected to one side of the L-shaped baffle plate and one side of the vertical plate, respectively. A support rod is fixedly connected to the side of the L-shaped baffle plate away from the vertical plate. Two inclined plates that intermittently abut against the corresponding support rods are symmetrically fixedly connected to the side of the mounting plate near the stirring seat.

[0012] Furthermore, the sewage conveying mechanism includes a connecting beam fixedly connected to the outer wall of one side of the two storage tanks that are close to each other. A sewage conveying pipe is fixedly connected through the top of the connecting beam. The bottom end of the sewage conveying pipe extends to the bottom of the connecting beam and is fixedly connected to a U-shaped water conveying pipe. Both ends of the U-shaped water conveying pipe face downwards and correspond to the first mixing tank and the second mixing tank, respectively.

[0013] Furthermore, two sliding rods are symmetrically fixedly connected to one side of the connecting beam. The same movable plate is slidably sleeved on the two sliding rods. A second return spring is sleeved on each of the two sliding rods. The two ends of the second return spring are fixedly connected to the movable plate and the side of the connecting beam that are close to each other, respectively. Two striking rods that abut against one side of the connecting beam are symmetrically fixedly connected to the side of the movable plate that is close to the connecting beam.

[0014] Furthermore, an L-shaped connecting plate is fixedly connected to the side of the movable plate away from the connecting beam, and a triangular block is fixedly connected to the bottom of the side of the L-shaped connecting plate close to the movable plate. A rotating ring is fixedly sleeved on the output shaft of the drive motor, and a toggle rod that intermittently abuts against the triangular block is fixedly connected to the rotating ring.

[0015] Furthermore, two L-shaped vibration transmission plates are symmetrically fixedly connected to the bottom sides of the connecting beam, and the two L-shaped vibration transmission plates are respectively fixedly sleeved on the outer walls of the two feeding pipes.

[0016] The beneficial effects of this invention are as follows: This invention features two intermittently alternating mixing tanks on a mixing base. While the first tank stores water for coagulation and mixing, the second tank discharges the coagulated wastewater. By intermittently rotating the mixing base, not only is coagulation efficiency ensured, but the amount of wastewater and coagulant added during each mixing cycle is automatically and quantitatively controlled, achieving precise proportion control. This ensures effective coagulation while saving on coagulant usage and optimizing the coagulation process. Furthermore, the mixing process vibrates the storage tank and feeding pipe, ensuring smoother feeding and storage and preventing blockages.

[0020] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] Example 1 like Figures 1-2 As shown, a precise quantitative coagulation device for wastewater treatment includes a mounting plate 1, a servo motor 3, a stirring base 4, and two storage tanks 6. Two support columns 2 are symmetrically fixedly connected to the bottom of the mounting plate 1 for supporting the entire mounting plate 1. The stirring base 4 is rotatably connected to one side of the mounting plate 1 for mixing wastewater with coagulant to complete the coagulation of the wastewater. The servo motor 3 is fixedly mounted on one side of the mounting plate 1, and its output shaft rotates through the mounting plate 1 and is fixedly connected to one side of the stirring base 4, driving the stirring base 4 to rotate back and forth for adjustment. By tilting the stirring base 4, intermittent alternation between quantitative mixing of wastewater and drainage can be achieved. The two storage tanks 6 are symmetrically fixedly connected to the top two sides of the stirring base 4, enabling automatic quantitative feeding of coagulant as the stirring base 4 rotates synchronously.

[0022] This invention can be used in the field of circulating purification equipment for water pollution treatment, and can also be applied to other fields of this invention.

[0023] Example 2 This embodiment is a further improvement on the previous embodiment: such as Figures 1-5 As shown, the top of the mixing base 4 is symmetrically provided with a first mixing tank 41 and a second mixing tank 43 on both sides. The bottom walls of both the first mixing tank 41 and the second mixing tank 43 are inclined. Inside the mixing base 4, a funnel-shaped drainage cavity 45 is provided between the first mixing tank 41 and the second mixing tank 43. The first mixing tank 41 and the funnel-shaped drainage cavity 45 are connected by a first drain outlet 42, and the second mixing tank 43 and the funnel-shaped drainage cavity 45 are connected by a second drain outlet 44. The bottom of the mixing base 4 is provided with a drain pipe 13 connected to the funnel-shaped drainage cavity 45. Starting the servo motor 3 can drive the mixing base 4 to rotate and adjust, such as... Figure 10 and Figure 11 As shown, when the stirring base 4 rotates to an inclined state, the first stirring tank 41 is in a water-filled state. At this time, after the wastewater is transported into the first stirring tank 41, it will not be discharged from the first drain outlet 42 into the bucket-shaped drainage chamber 45. Meanwhile, the second stirring tank 43 is in a drainage state. The wastewater and coagulant in the second stirring tank 43 are coagulated and stirred for a period of time before being discharged from the second drain outlet 44 into the bucket-shaped drainage chamber 45, and finally discharged outwards through the drain pipe 13. The entire mounting plate 1 can be installed above the sedimentation tank via two support columns 2. The coagulated wastewater can be directly discharged into the sedimentation tank through the drain pipe 13 for sedimentation. Regardless of whether the drain pipe 13 is tilted to the left or right with the stirring base 4, the wastewater can be discharged into the sedimentation tank. Alternatively, the drain pipe 13 can also be connected to a drain hose, which is connected to the baffle plate coagulation tank, allowing the coagulated wastewater to be directly discharged into the baffle plate coagulation tank for continuous treatment. During the discharge of coagulated wastewater from the second mixing tank 43, the filtered wastewater can be coagulated and stirred in the first mixing tank 41. After the wastewater in the second mixing tank 43 is discharged, the servo motor 3 is restarted to drive the mixing seat 4 to rotate in the reverse direction, so that the first mixing tank 41 is in a drainage state, and the coagulated wastewater is discharged into the bucket-shaped drainage chamber 45 through the first drain outlet 42. Meanwhile, the second mixing tank 43 is in a water storage state, and the filtered wastewater is then transported to the second mixing tank 43 for coagulation. This operation is repeated, and by setting up the alternating use of the two mixing tanks, time can be saved while achieving continuous processing and ensuring work efficiency. In order to facilitate the mixing seat 4 to better meet the two states of simultaneous water storage and drainage, the forward and reverse rotation adjustment angle of the mixing seat 4 should be controlled between 30-35 degrees. Figure 11 As shown, the stirring base 4 rotates counterclockwise by 30 degrees under the control of the servo motor 3, which is the optimal design angle.

[0024] In one aspect of this embodiment, stirring shafts 15 are horizontally rotatably connected to both the first stirring tank 41 and the second stirring tank 43. At least one set of stirring blades 16 is provided on the outer wall of each stirring shaft 15. The ends of both stirring shafts 15 away from the mounting plate 1 are sealed and rotatably pass through one side of the stirring base 4 and are fixedly fitted with driven pulleys 17. A drive motor 10 is fixedly connected to the top edge of the stirring base 4 away from the mounting plate 1. A drive pulley 14 is fixedly fitted on the output shaft of the drive motor 10. The same synchronous belt 18 is driven and fitted onto the drive pulley 14 and the two driven pulleys 17. When the drive motor 10 is started, the synchronous belt 18 simultaneously drives the two stirring shafts 15 to rotate, thereby driving the stirring blades 16 to rotate, thus achieving coagulation and stirring of the wastewater in the first stirring tank 41 and the second stirring tank 43 respectively.

[0025] Example 3 This embodiment is a further improvement on the previous embodiment: such as Figures 1-7 As shown, two vertical plates 5 are symmetrically fixedly connected to the top two sides of the mixing base 4, and two storage tanks 6 are respectively fixedly connected to one side of the two vertical plates 5. The bottoms of the two storage tanks 6 are inclined. The top sides of the two storage tanks 6, which are close to each other, are each fixedly provided with a feeding pipe 9 for adding coagulant. The bottom sides of the two storage tanks 6, which are close to each other, are each fixedly provided with a feeding pipe 12 for dispensing coagulant. The bottom ends of the two feeding pipes 12 correspond to the first mixing tank 41 and the second mixing tank 43, respectively. One side of each of the two vertical plates 5 is provided with a set of metering components for controlling the corresponding feeding pipes 12 to dispense coagulant in a quantitative manner. The two storage tanks 6 can rotate and move synchronously with the mixing base 4 via the vertical plates 5, so that the two feeding pipes 12 can always maintain the corresponding feeding state with the first mixing tank 41 and the second mixing tank 43, thereby achieving the effect of automatically dispensing coagulant in a quantitative manner to the first mixing tank 41 and the second mixing tank 43. Both storage bins 6 are fixedly connected to the corresponding vertical plates 5 by two symmetrically arranged reinforcing rods 33, which can improve the connection stability between the storage bins 6 and the vertical plates 5.

[0026] In one aspect of this embodiment, the metering component includes an L-shaped baffle plate 20 that is slidably connected to the bottom of one side of the vertical plate 5, and the top side of the L-shaped baffle plate 20 is sealed and fitted to the bottom end of the feeding pipe 12. A discharge hole 201, which intermittently communicates with the feeding pipe 12, is provided on the top side of the L-shaped baffle plate 20. When the L-shaped baffle plate 20 is in its initial state, such as... Figure 7As shown, the discharge hole 201 and the feeding pipe 12 are misaligned at this time. The bottom of the feeding pipe 12 can be blocked by the L-shaped baffle plate 20, preventing the coagulant in the feeding pipe 12 from falling out. When the L-shaped baffle plate 20 moves, the discharge hole 201 and the feeding pipe 12 are aligned. At this time, the coagulant in the feeding pipe 12 can fall downward through the discharge hole 201 and into the first mixing tank 41 or the second mixing tank 43, thus completing the coagulant feeding effect.

[0027] In one aspect of this embodiment, a guide rod 21 is slidably connected through one side of the L-shaped baffle 20, and one end of the guide rod 21 is fixedly connected to one side of the vertical plate 5. A first return spring 22 is sleeved on the outer wall of the guide rod 21, and both ends of the first return spring 22 are fixedly connected to one side of the L-shaped baffle 20 and one side of the vertical plate 5, respectively. A support rod 23 is fixedly connected to the side of the L-shaped baffle 20 away from the vertical plate 5. Two inclined plates 19, which intermittently abut against the corresponding support rods 23, are symmetrically fixedly connected to the side of the mounting plate 1 near the stirring seat 4. Figure 10 and Figure 11 As shown, when the mixing base 4 rotates counterclockwise by 30 degrees, the first mixing tank 41 is in a water storage state, while the second mixing tank 43 is in a drainage state. Similarly, the coagulant in the storage tank 6 near the first mixing tank 41 will not enter the corresponding feeding pipe 12, which is already full of coagulant and is in a feeding state. As the vertical plate 5 and the storage tank 6 rotate synchronously with the mixing base 4, they will drive the L-shaped baffle plate 20 to rotate synchronously. When the L-shaped baffle plate 20 drives the support rod 23 to move and abuts against the inclined plate 19, the support rod 23 can push the L-shaped baffle plate 20 to move and simultaneously squeeze the first return spring 22. The L-shaped baffle plate 20 will simultaneously drive the discharge hole 201 to align with the bottom end of the feeding pipe 12. At this time, the coagulant in the feeding pipe 12 can be directly fed into the first mixing tank 41 below and mixed with the sewage to complete the coagulation work. Since the amount of coagulant loaded into the feeding pipe 12 is the same each time, the amount of coagulant added each time can be adjusted according to the amount of wastewater delivered, thus enabling more effective coagulation without wasting coagulant. Simultaneously, the coagulant in the storage tank 6 near the second mixing tank 43 can enter the corresponding feeding pipe 12. Since this feeding pipe 12 has already been filled with coagulant, it is currently empty. The coagulant in the storage tank 6 can then fill the feeding pipe 12, ready for the next quantitative feeding. Furthermore, because the angle prevents the support rod 23 from contacting the corresponding inclined plate 19, the L-shaped baffle 20 remains in its initial state under the elastic force of the first return spring 22, meaning the discharge hole 201 and the feeding pipe 12 are misaligned, thus blocking the feeding pipe 12 and preventing the entering coagulant from falling, thereby achieving automatic quantitative feeding.

[0028] Example 4 This embodiment is a further improvement on the previous embodiment: such as Figures 1-8 As shown, the purification equipment also includes a wastewater conveying mechanism located between the two storage tanks 6, used to convey the filtered wastewater to the mixing base 4 for coagulation. The wastewater conveying mechanism includes a connecting beam 7 fixedly connected to the outer wall of the two storage tanks 6 on their adjacent sides. A wastewater conveying pipe 8 is fixedly connected through the top of the connecting beam 7, and the bottom end of the wastewater conveying pipe 8 extends below the connecting beam 7 and is fixedly connected to a U-shaped water conveying pipe 11. Both ends of the U-shaped water conveying pipe 11 face downwards and correspond to the first mixing tank 41 and the second mixing tank 43, respectively. To facilitate the rotation and adjustment of the mixing base 4, a water conveying hose can be connected to the top of the wastewater conveying pipe 8, ensuring that the wastewater conveying pipe 8 can rotate synchronously with the rotation of the mixing base 4. The other end of the water conveying hose is directly connected to a metering water pump, and the inlet of the water pump is connected to the wastewater tank through a pipe, allowing wastewater in the wastewater tank to be intermittently conveyed to the first mixing tank 41 and the second mixing tank 43 via the metering water pump, water conveying hose, wastewater conveying pipe 8, and U-shaped water conveying pipe 11. Figure 11 As shown, due to the U-shaped water supply pipe 11, when the first mixing tank 41 is in a water storage state, the U-shaped water supply pipe 11 is inclined downward near the outlet end of the first mixing tank 41. At this time, after the sewage is transported through the sewage conveying pipe 8, it can be directly transported into the first mixing tank 41 through the U-shaped water supply pipe 11. When the second mixing tank 43 is in a discharge state, the U-shaped water supply pipe 11 is inclined upward near the outlet end of the second mixing tank 43. Therefore, when the sewage is transported, it will only enter the first mixing tank 41 and will not enter the second mixing tank 43. Thus, without the need for valve control, the normal transport of sewage can be ensured simply by adjusting the rotation of the mixing base 4 itself.

[0029] Example 5 This embodiment is a further improvement on the previous embodiment: such as Figures 1-9As shown, two sliding rods 24 are symmetrically fixedly connected to one side of the connecting beam 7. A movable plate 25 is slidably mounted on each sliding rod 24. A second return spring 26 is mounted on each sliding rod 24. The two ends of the second return spring 26 are fixedly connected to the movable plate 25 and the side of the connecting beam 7 that are close to each other. Two striking rods 27 that abut against one side of the connecting beam 7 are symmetrically fixedly connected to the side of the movable plate 25 that is close to the connecting beam 7. When the movable plate 25 moves, causing the striking rods 27 to move away from the connecting beam 7, one end of the striking rod 27 disengages from the connecting beam 7, and the second return spring 26 is in a stretched state. When the movable plate 25 returns to its original position under the elastic force of the second return spring 26, it can quickly reset the striking rods 27, achieving a striking effect on the connecting beam 7. Since the connecting beam 7 is connected between the two storage tanks 6, the vibration from striking the connecting beam 7 can be transmitted to the two storage tanks 6, causing the coagulant inside the two storage tanks 6 to accumulate to one side when tilted. Two L-shaped vibration transmission plates 30 are symmetrically fixedly connected to both sides of the bottom of the connecting beam 7, and the two L-shaped vibration transmission plates 30 are respectively fixedly sleeved on the outer walls of the two feeding pipes 12. When the striking rod 27 strikes and vibrates the connecting beam 7, the vibration can be transmitted to the two L-shaped vibration transmission plates 30, and then effectively transmitted to the two feeding pipes 12. When the feeding pipes 12 are feeding materials, the vibration can complete the rapid feeding; when the feeding pipes 12 are receiving materials, the vibration can complete the rapid storage, avoiding blockages during the feeding and storage process, which would affect normal feeding and storage.

[0030] In one aspect of this embodiment, an L-shaped connecting plate 28 is fixedly connected to the side of the movable plate 25 away from the connecting beam 7. A triangular block 29 is fixedly connected to the bottom of the side of the L-shaped connecting plate 28 closest to the movable plate 25. A rotating ring 31 is fixedly sleeved on the output shaft of the drive motor 10. A lever 32 that intermittently abuts against the triangular block 29 is fixedly connected to the rotating ring 31. When the drive motor 10 is started, it can not only drive the two stirring shafts 15 to rotate and complete the coagulation and stirring of sewage through the stirring blades 16, but also drive the rotating ring 31 to rotate and simultaneously drive the lever 32 to rotate. When the lever 32 abuts against the inclined surface of the triangular block 29, it can push the L-shaped connecting plate 28 to move, thereby driving the movable plate 25 to move. When the lever 32 continues to rotate with the rotating ring 31 and disengages from the triangular block 29, it can be driven by the elastic force of the second return spring 26 to quickly return the movable plate 25 and the L-shaped connecting plate 28 to move, thereby achieving the knocking effect on the connecting beam 7.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the servo motor 3 and the drive motor 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
