Description

Technical Field

[0001] This invention relates to the field of rubber paste production technology, and more specifically to an environmentally friendly process for rubber paste production. Background Technology

[0002] Rubber plasters are topical adhesive patches made by mixing drug or herbal extracts with a rubber matrix and then applying the mixture to a backing material (such as cloth or paper). The production process generates industrial wastewater containing residual raw drug components. This wastewater requires targeted treatment to improve water resource utilization and avoid waste and environmental pollution. The treatment process involves adding specialized agents to the wastewater and ensuring thorough mixing and reaction. This neutralizes the residual drug components, ensuring the treated water meets discharge or reuse standards.

[0003] For example, patent document CN118084095A, entitled "A Wastewater Dosing Treatment Device for a Pharmaceutical Production System," includes a mixing tank with a top cover fixedly connected to its top and an outlet cover threaded to one side. The mixing tank contains a dosing and mixing mechanism. This mechanism, when the mixing plate A rotates, thoroughly agitates the wastewater in the mixing tank. As the mixing plate A rises, the bottom and upper water layers are mixed.

[0004] However, in the wastewater treatment process described in the above literature, the dosing path of the chemical solution could not be synchronized with the movement trajectory of the mixing plate into the wastewater, resulting in a relatively slow diffusion rate of the chemical solution in the wastewater. This made it difficult to quickly form a uniformly distributed reaction environment, reducing the mixing efficiency of the chemical solution and wastewater, and thus affecting the improvement of the overall treatment efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly process for the production of rubber paste, which solves the technical problem mentioned in the background art where the diffusion rate of the pharmaceutical solution in wastewater is relatively slow, making it difficult to quickly form a uniformly distributed reaction environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly process for producing rubber paste includes the following steps: S1. Pretreatment: Wastewater from the rubber compound production process is fed into a pretreatment tank for pretreatment. The pretreatment tank is equipped with a grid and a screen to remove large suspended solids from the wastewater. S2. Mixing reaction: Water is introduced into the mixing equipment, and the chemical solution is added according to the wastewater quality. The mixing equipment is used to quickly mix the chemical solution with the wastewater to neutralize the acidity and alkalinity of the wastewater and the chemical potency. S4. Sedimentation: The wastewater after the mixed reaction is sent to a sedimentation tank and left to stand for a certain period of time to obtain preliminarily clarified water; S5. Filtration: The clarified water passes through the filter bed to remove the remaining fine suspended solids and colloidal substances; S6. Disinfection: Add disinfectant to the filtered water to kill bacteria, viruses and other pathogenic microorganisms in the water.

[0007] The mixing device in S2 includes a mixing tank, a rotating shaft rotatably mounted inside the mixing tank, a rotating assembly for driving the rotating shaft to rotate at the top of the mixing tank, a rotating plate slidably mounted on the rotating shaft, a lifting assembly for driving the rotating plate to rise and fall inside the mixing tank, a drug storage cylinder rotatably mounted at the top of the rotating shaft, the drug storage cylinder being fixedly connected to the mixing tank, a cavity being opened inside the rotating shaft and connected to the drug storage cylinder, multiple telescopic pipes communicating with the cavity being fixedly mounted on the outer periphery of the rotating shaft, multiple crushing components being arranged along the circumference of the rotating plate, the crushing components being connected to the corresponding telescopic pipes, during the process of the rotating plate driving the crushing components to move vertically and rotate, the liquid medicine in the drug storage cylinder flows into the telescopic pipe through the cavity, and then is introduced into the crushing components to be released outward, so that the liquid medicine is injected into the wastewater along the trajectory of the movement of the crushing components, and at the same time the water flow drives the crushing components to crush the drug coagulation in the wastewater, and simultaneously mixes the liquid medicine and the wastewater.

[0008] Furthermore, the crushing assembly includes a rotating rod, a crushing plate fixedly disposed on the outer periphery of the rotating rod, and a water wheel fixedly disposed on the rotating rod. The rotating plate has mounting holes evenly distributed along its circumference, and a first connecting frame is disposed in the mounting holes. The rotating rod is rotatably connected to the center of the first connecting frame.

[0009] Furthermore, the rotating rod has a flow cavity inside along its axial direction, and through holes are evenly distributed on its outer periphery. The through holes are connected to the flow cavity. The top of the rotating rod is rotatably connected to the telescopic tube, which is connected to the flow cavity.

[0010] Furthermore, the outer periphery of the crushing component is provided with a guide tube, which is fixedly connected to the mounting hole. The first connecting frame is fixedly connected to the guide tube. A sealing plate is rotatably provided at the bottom of the rotating plate. Multiple guide holes are opened on the sealing plate. A control component for driving the sealing plate to open and close the guide tube is provided on the rotating shaft.

[0011] Furthermore, the control component includes a sliding frame slidably mounted on the rotating shaft and a sliding column fixedly mounted on the sliding frame. The sliding frame is fixedly connected to the closed plate. A control groove is formed on the outer periphery of the rotating shaft. The control groove is slidably connected to the sliding column. The control groove includes a vertical groove one, a vertical groove two, a spiral groove one, and a spiral groove two. Both vertical groove one and vertical groove two are arranged along the axial direction of the rotating shaft. Spiral groove one is connected to the top of vertical groove one and vertical groove two, respectively. Spiral groove two is connected to the bottom of vertical groove one and vertical groove two, respectively.

[0012] Furthermore, a blocking column is slidably disposed inside the first flow cavity along its axial direction, and a second flow cavity is formed inside the blocking column along its axial direction. Through holes 2 communicating with the second flow cavity are evenly distributed on the outer periphery of the blocking column. The first and second through holes 1 and 2 are matched one-to-one. A spring is fixedly disposed between the top of the blocking column and the first flow cavity. The bottom of the blocking column extends to the outside of the rotating rod. The bottom end of the blocking column is hemispherical and slides with the closing plate.

[0013] Furthermore, the diameter of the top of the guide tube is smaller than the diameter of the bottom.

[0014] Furthermore, the rotating assembly includes a motor fixedly mounted on the top of the mixing tank and a gear one fixedly mounted on the output end of the motor. The top end of the rotating shaft extends to the top of the mixing tank and is fixedly mounted with a gear two, which meshes with the gear one.

[0015] Furthermore, the lifting assembly includes a first fixing plate and a second fixing plate, which are respectively fixedly installed at the top and bottom of the rotating shaft. A reciprocating screw is rotatably installed between the first fixing plate and the second fixing plate. The reciprocating screw passes through the rotating plate and is threadedly connected to the rotating plate. A transmission assembly for driving the reciprocating screw to rotate is installed at the top of the mixing tank.

[0016] Furthermore, the transmission assembly includes a gear three fixedly mounted on the top of the reciprocating lead screw and a gear ring fixedly mounted on the top of the mixing tank, the gear ring meshing with the gear three.

[0017] The beneficial effects of this invention are as follows: This invention features multiple telescopic tubes fixedly arranged around the outer periphery of a rotating shaft, communicating with a cavity. Multiple crushing components are arranged circumferentially on a rotating plate, and each crushing component is connected to a corresponding telescopic tube. In actual use, the lifting component drives the rotating plate to rise and fall. During this process, the liquid medicine in the storage cylinder flows through the rotating shaft and cavity into the telescopic tubes, then into the crushing components and is released outwards. The liquid medicine is dynamically added throughout the entire process, following the downward trajectory of the rotating plate, facilitating rapid diffusion of the liquid medicine across various levels and areas of the water body. Simultaneously, the water flow drives the crushing components to break up drug coagulations in the wastewater, reducing the particle size and increasing the specific surface area of ​​the coagulated particles, allowing for more thorough contact with the liquid medicine and improving the reaction rate, while preventing the coagulated particles from clogging the pipes. Furthermore, the convection and eddy diffusion effects generated by the crushing components rapidly expand the diffusion radius of the liquid medicine in the wastewater, quickly forming a homogeneous reaction environment and improving overall mixing efficiency and reaction uniformity.

[0020] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] An environmentally friendly process for producing rubber paste includes the following steps: S1. Pretreatment: Wastewater from the rubber compound production process is fed into a pretreatment tank for pretreatment. The pretreatment tank is equipped with a grid and a screen to remove large suspended solids from the wastewater.

[0022] S2. Mixing reaction: Water is introduced into the mixing equipment, and the chemical solution is added according to the wastewater quality. The mixing equipment is used to quickly mix the chemical solution with the wastewater to neutralize the acidity, alkalinity and chemical potency in the wastewater.

[0023] S4. Sedimentation: The wastewater after the mixed reaction is sent to a sedimentation tank and left to stand for a certain period of time to obtain preliminarily clarified water.

[0024] S5. Filtration: The clarified water passes through the filter bed to remove the remaining fine suspended solids and colloidal substances.

[0025] S6. Disinfection: Add disinfectant to the filtered water to kill bacteria, viruses and other pathogenic microorganisms in the water.

[0026] like Figures 1-2 As shown, the mixing equipment in S2 includes a mixing tank 1, which is a cylindrical structure. An inlet pipe 2 and an outlet pipe 3, communicating with the interior of the mixing tank 1, are respectively installed at the top and bottom. Control valves are installed on the inlet pipe 2 and the outlet pipe 3 to control the inflow and outflow of wastewater. A rotating shaft 4 is rotatably installed inside the mixing tank 1, with its two ends rotatably connected to the top and bottom centers of the mixing tank 1, respectively. A rotating assembly for driving the rotating shaft 4 is installed at the top of the mixing tank 1. The rotating assembly includes a motor 5 fixedly installed at the top of the mixing tank 1 and a gear 6 fixedly mounted on the output end of the motor 5. The top end of the rotating shaft 4 extends to the top of the mixing tank 1 and is fixedly mounted on a gear 7, which meshes with gear 6. When the motor 5 is started, the motor 5 drives gear 6 to rotate, gear 6 drives gear 7 to rotate, and gear 7 drives the rotating shaft 4 to rotate.

[0027] like Figure 2 and Figure 3 As shown, a rotating plate 8 is slidably mounted on the outer periphery of the rotating shaft 4. A through hole is formed in the center of the rotating plate 8, which is then fitted onto the outer periphery of the rotating shaft 4. A lifting assembly for raising and lowering the rotating plate 8 is installed inside the mixing tank 1. The lifting assembly includes a first fixing plate 9 and a second fixing plate 10, respectively fixedly mounted on the top and bottom of the rotating shaft 4. A reciprocating screw 11 is rotatably mounted between the first fixing plate 9 and the second fixing plate 10. Both ends of the reciprocating screw 11 are smooth sections, and both ends rotatably pass through the first fixing plate 9 and the second fixing plate 10, respectively. The reciprocating screw 11 passes through the rotating plate 8 and is threadedly connected to it. A transmission assembly for rotating the reciprocating screw 11 is installed on the top of the mixing tank 1. The transmission assembly includes a third gear 12 fixedly mounted on the top of the reciprocating screw 11 and a gear ring 13 fixedly mounted on the top of the mixing tank 1. The gear ring 13 meshes with the third gear 12, and the central axis of the gear ring 13 coincides with the axis of the rotating shaft 4.

[0028] When the rotating shaft 4 rotates, the reciprocating screw 11, driven by the fixed plate 9 and the fixed plate 10, revolves synchronously around the rotating shaft 4, thereby driving the rotating plate 8 to rotate together. Simultaneously, the reciprocating screw 11 drives the gear 12 to revolve synchronously around the rotating shaft 4. The gear 12 meshes with the gear ring 13, generating its own rotation under this meshing action. The gear 12 then drives the reciprocating screw 11 to rotate synchronously, causing the rotating plate 8 to rise and fall. Thus, the rotating plate 8 simultaneously rises and falls during its rotation.

[0029] like Figure 1 and Figure 2As shown, a medicine storage cylinder 14 is rotatably mounted on the top of the rotating shaft 4. Multiple support rods 15 are fixedly mounted on the top of the medicine storage cylinder 14 along its circumference, and the bottom ends of the support rods 15 are fixedly connected to the mixing tank 1. A downwardly extending cavity 16 is formed on the top surface of the rotating shaft 4 along its axial direction. The top of the cavity 16 is connected to the medicine storage cylinder 14. Multiple connecting pipes 17, which are fixedly connected to the cavity 16, are fixedly mounted on the outer circumference of the rotating shaft 4. The multiple connecting pipes 17 are located inside the mixing tank 1 and are evenly distributed along the circumference of the rotating shaft 4. A telescopic pipe 18, which is a metal corrugated pipe, is fixedly connected to the end of each connecting pipe 17 away from the rotating shaft 4. Multiple crushing components are mounted on the rotating plate 8 along its circumference, and these components are evenly distributed along the circumference of the rotating plate 8, with each component corresponding to one of the telescopic pipes 18.

[0030] As the rotating plate 8 drives the crushing component to move vertically and revolve around the rotating shaft 4, the liquid medicine in the storage cylinder 14 flows through the cavity 16 into the telescopic pipe 18, and then into the crushing component for release. This allows the liquid medicine to be continuously injected into the wastewater along the trajectory of the crushing component, facilitating rapid diffusion of the liquid medicine in various layers and areas of the water body. Simultaneously, the water flow drives the crushing component to break up drug coagulations in the wastewater. Furthermore, the crushing component simultaneously stirs and mixes the injected liquid medicine and wastewater, further improving the mixing degree and quickly creating a uniformly distributed reaction environment, thus enhancing the reaction effect between the liquid medicine and wastewater.

[0031] like Figure 6 and Figure 7 As shown, the crushing assembly includes a rotating rod 19, multiple crushing plates 20 fixedly installed on the outer periphery of the rotating rod 19, and a water wheel 21 fixedly installed on the bottom of the rotating rod 19. The rotating plates 8 have uniformly spaced mounting holes along their circumference, and a first connecting frame 22 is installed within each mounting hole. The rotating rod 19 is rotatably connected to the center of the corresponding first connecting frame 22. A guide tube 23 covers the outer periphery of the crushing assembly. The guide tube 23 guides the water flow, directing its directional flow and providing a stable and concentrated impact force to the water wheel 21. This helps increase the rotational speed of the water wheel 21, thereby increasing the rotational speed of the rotating rod 19 and the crushing plates 20, and ultimately increasing the crushing efficiency of the drug coagulation. The diameter of the top of the guide tube 23 is smaller than the diameter of the bottom, causing the water flow to accelerate naturally as it passes through the guide tube 23. This further increase in flow velocity increases the impact kinetic energy on the water wheel 21, allowing the water wheel 21 to rotate even faster.

[0032] like Figures 4-6As shown, the diameter of the bottom of the guide tube 23 matches the diameter of the mounting hole, and the outer periphery of the bottom of the guide tube 23 is fixedly connected to the inner wall of the mounting hole. The first connecting frame 22 includes a fixing ring and a connecting rod that is uniformly fixedly installed along its circumference, with the other end of the connecting rod fixedly connected to the guide tube 23. The rotating rod 19 rotatably passes through the fixing ring and extends downward to below the fixing ring. The water wheel 21 consists of six helical blades, and the six blades are evenly distributed along the outer periphery of the bottom of the rotating rod 19. Multiple crushing plates 20 are equidistantly arranged along the axial direction of the rotating rod 19. A second connecting frame 24 is fixedly installed on the top of the guide tube 23. The second connecting frame 24 has the same structure as the first connecting frame 22, and the second connecting frame 24 is rotatably connected to the rotating rod 19 to increase the stability of the rotating rod 19 during rotation.

[0033] During the vertical movement of the rotating plate 8, the water flows upward through the guide tube 23, impacting the blades of the water wheel 21 and driving it to rotate. The water wheel 21 drives the crushing plate 20 to rotate through the rotating rod 19, forming a shearing and impacting effect on the drug coagulation in the wastewater, thereby breaking up and crushing the drug coagulation. This reduces the particle size of the crushed coagulation and increases its specific surface area, allowing it to contact the drug solution more fully, improving the reaction rate, and preventing the coagulation from clogging the pipes.

[0034] like Figure 5 and Figure 6 As shown, the rotating rod 19 has a flow cavity 25 inside along its axial direction, and through holes 26 are evenly distributed on its outer periphery along its axial direction, and the through holes 26 are connected to the flow cavity 25. The top of the rotating rod 19 is rotatably connected to the telescopic tube 18 through a rotary joint to prevent the telescopic tube 18 from obstructing the rotation of the rotating rod 19. The telescopic tube 18 is connected to the flow cavity 25 to facilitate the flow of the medicine into the flow cavity 25.

[0035] As the rotating plate 8 drives the rotating rod 19 to move vertically and revolve around the rotating axis 4, the liquid medicine in the storage cylinder 14 flows through the cavity 16 into the connecting pipe 17 and the telescopic pipe 18, then into the flow chamber 25, and is released outward through the through hole 26. This allows the liquid medicine to be continuously and dynamically injected into the wastewater along the trajectory of the rotating rod 19. This facilitates the rapid diffusion of the liquid medicine in various layers and areas of the water body, which helps to increase the diffusion rate of the liquid medicine in the wastewater and promotes thorough and uniform mixing of the liquid medicine and the wastewater. Furthermore, the rotating rod 19 rotates under the drive of the water wheel 21, which drives the through hole 26 to rotate. The rotation of the through hole 26 evenly sprinkles the liquid medicine into the wastewater, further enhancing the diffusion effect and making the mixture of liquid medicine and wastewater more uniform. Simultaneously, the convective and eddy diffusion effects generated by the rotating rod 19 driving the crushing plate 20 to rotate rapidly expand the diffusion radius of the drug solution in the wastewater, further enhancing the diffusion efficiency. Thus, through the shearing and stirring action of the crushing plate 20 and the water wheel 21, the micro-mixing of the drug solution and wastewater is strengthened, quickly forming a uniformly distributed reaction environment and improving the reaction effect between the drug solution and wastewater. At the same time, the time for the crushed drug coagulation to bind with the drug solution is shortened, strengthening the effect of the drug solution on dispersing the drug coagulation.

[0036] Furthermore, compared to the traditional method of sprinkling the solution on the water surface, this method can prevent some of the agent from adsorbing onto the surface and forming a thin film, thus preventing it from actually entering the water and reacting with pollutants. This would reduce the effective utilization rate of the solution and cause waste. Injecting the solution directly into various layers and areas of the water body allows the agent to fully exert its effect, thereby avoiding excessively high concentrations in local areas and preventing sedimentation or aggregation due to local oversaturation.

[0037] To ensure smooth release of the liquid medicine through the through-hole 26, a pressurizing device, such as an air compressor or hydraulic pump, can be installed in the medicine storage cylinder 14. This device actively increases the pressure inside the medicine storage cylinder 14, providing continuous power for the flow of the liquid medicine and preventing obstruction of flow due to factors such as pipeline resistance and liquid medicine viscosity. The pressurizing device is existing technology and will not be described in detail here.

[0038] like Figure 8 and Figure 9 As shown, the bottom end of the guide tube 23 is flush with the bottom surface of the rotating plate 8. A sealing plate 27 is rotatably mounted on the bottom of the rotating plate 8, with its top surface in contact with the bottom surface of the rotating plate 8. The sealing plate 27 can rotate relative to the rotating plate 8 and also move synchronously with the rotating plate 8. Multiple guide holes 28 are provided on the sealing plate 27, the number of which is the same as the number of mounting holes. The diameter of each guide hole 28 is larger than the diameter of the corresponding guide tube 23, which reduces the resistance to water flow when the guide holes 28 are aligned and connected to the corresponding guide tubes 23, allowing the water to flow smoothly into the guide tubes 23.

[0039] like Figures 8-9As shown, a control assembly for driving the sealing plate 27 to open and close the guide tube 23 is installed on the rotating shaft 4. The control assembly includes a sliding frame 29 slidably mounted on the rotating shaft 4 and a sliding column 30 fixedly mounted on the sliding frame 29. The sliding column 30 has a cylindrical structure. The sliding frame 29 is fixedly connected to the sealing plate 27. The sealing plate 27 has a through hole in its center. The sliding frame 29 includes a sliding ring and a fixed rod evenly fixedly mounted along its outer circumference. The sliding column 30 is fixedly connected to the inner wall of the fixed ring. The other end of the fixed rod is fixedly connected to the inner wall of the through hole in the center of the sealing plate 27. By setting the sliding frame 29, interference of the reciprocating screw 11 on the rotation of the sealing plate 27 can be avoided.

[0040] like Figures 8-10 As shown, a control groove is formed on the outer circumference of the rotating shaft 4, and the control groove is slidably connected to the sliding column 30. When the rotating shaft 4 rotates, the sliding column 30 drives the sliding frame 29 to rotate, and the sliding frame 29 drives the closing plate 27 to rotate, ensuring that the closing plate 27 rotates together with the rotating plate 8. The control groove includes vertical groove 1 31, vertical groove 2 32, spiral groove 1 33, and spiral groove 2 34. Vertical groove 1 31 and vertical groove 2 32 are both arranged along the axial direction of the rotating shaft 4. Spiral groove 1 33 is connected to the top of vertical groove 1 31 and vertical groove 2 32 respectively, and spiral groove 2 34 is connected to the bottom of vertical groove 1 31 and vertical groove 2 32 respectively. Furthermore, the height of the control groove matches the thread height on the outer circumference of the reciprocating screw 11.

[0041] As the rotating plate 8 descends, it causes the sealing plate 27 to move downwards. The sealing plate 27, through the sliding frame 29, drives the sliding column 30 to move along the vertical groove 31. At this time, the guide hole 28 on the sealing plate 27 is aligned and connected with the guide cylinder 23, ensuring that the water flows smoothly into the guide cylinder 23.

[0042] When the sliding column 30 slides from the vertical groove 31 into the spiral groove 33, the sliding column 30, guided by the spiral groove 33, drives the sliding frame 29 to rotate. The sliding frame 29 drives the sealing plate 27 to rotate synchronously. The sealing plate 27 causes the guide hole 28 and the guide cylinder 23 to gradually misalign until the sliding column 30 enters the vertical groove 32. The guide hole 28 and the guide cylinder 23 are completely misaligned, and the sealing plate 27 seals the guide cylinder 23, thus keeping the wastewater at the bottom of the mixing tank 1 inside the guide cylinder 23. At the same time, the reciprocating screw 11 drives the rotating plate 8 to rise, and the sliding column 30 moves upward along the vertical groove 32, maintaining the sealing state of the sealing plate 27. The guide cylinder 23 then lifts the wastewater from the bottom of the mixing tank 1 to the surface.

[0043] During the upward movement of the rotating plate 8, when the sliding column 30 slides into the spiral groove 34, under the reverse guidance of the spiral groove 34, the sliding frame 29 drives the closed plate 27 to rotate in the opposite direction, and the guide hole 28 and the guide cylinder 23 gradually align. During this process, the wastewater remaining in the guide cylinder 23 flows into the surface water of the mixing tank 1 until the sliding column 30 re-enters the vertical groove 31, and the guide hole 28 and the guide cylinder 23 are completely connected, completing one cycle.

[0044] This cyclic action enables continuous circulation of wastewater from bottom to top within the mixing tank 1, breaking down the mixing barrier between the bottom and surface wastewater, improving the overall mixing efficiency of wastewater and chemical solution, further optimizing reaction uniformity, and enhancing the overall efficiency of wastewater treatment.

[0045] like Figure 4 , Figures 7-9 As shown, a blocking post 35 is slidably installed inside the flow cavity 25 along its axial direction. The blocking post 35 can move vertically relative to the flow cavity 25. A second flow cavity 36 is formed inside the blocking post 35 along its axial direction, and the second flow cavity 36 communicates with the flow cavity 25. Through holes 37 communicating with the second flow cavity 36 are evenly formed on the outer periphery of the blocking post 35, and the first through hole 26 and the second through hole 37 are matched one-to-one. A spring 38 is fixedly installed between the top of the blocking post 35 and the flow cavity 25. The bottom of the blocking post 35 extends to the outside of the rotating rod 19. The bottom end of the blocking post 35 is hemispherical and slides with the closing plate 27.

[0046] As the rotating rod 19 moves downward with the rotating plate 8, the spring 38 remains in a naturally extended state. At this time, through hole 26 and through hole 37 are aligned and connected, ensuring smooth outward release of the liquid medicine. During the rotation of the sealing plate 27 and its gradual sealing of the guide tube 23, its surface forms a sliding fit with the bottom end of the blocking column 35, synchronously driving the blocking column 35 upward and compressing the spring 38. The spring 38 stores elastic potential energy to provide power for the subsequent reset of the blocking column 35. The upward movement of the blocking column 35 causes through hole 37 to completely misalign with through hole 26, thereby achieving a seal on through hole 26. This prevents the continuous inflow of liquid medicine after the guide tube 23 is sealed, effectively preventing excessively high local concentrations of liquid medicine, reducing waste, and improving the accuracy of liquid medicine dosing.

[0047] like Figure 5As shown, multiple stirring plates 39 are evenly distributed circumferentially around the outer periphery of the rotating plate 8. When the rotating plate 8 rotates, the stirring plates 39 agitate the edges of the wastewater, avoiding dead zones. Simultaneously, during the lifting and lowering of the rotating plate 8, the telescopic tube 18 extends and retracts synchronously via the rotating rod 19. When the telescopic tube 18 extends, its agitation force on the wastewater gradually increases under the action of the rotating shaft 4, connecting pipe 17, and rotating rod 19. When the telescopic tube 18 shortens, the agitation force weakens accordingly. Thus, through the repetitive cycle of these actions, the telescopic rod's extension and retraction, combined with its rotation, creates a periodic variable-speed agitation mode for the wastewater. Compared to the traditional uniform-speed agitation mode, this breaks the flow field isolation zone formed by traditional uniform-speed agitation, preventing some areas of water flow from remaining relatively still or only undergoing weak movement due to force balance, thus isolating them from the surrounding actively flowing water. This prevents the chemical solution and wastewater from fully exchanging and mixing in these areas, resulting in more thorough mixing of wastewater and chemical solution, improving mixing uniformity and overall mixing efficiency.

[0048] Working principle: During wastewater treatment, the wastewater enters the mixing tank 1 through the inlet pipe 2. The motor 5 is started, which drives gear 6 to rotate, gear 6 drives gear 7 to rotate, and gear 7 drives the rotating shaft 4 to rotate.

[0049] When the rotating shaft 4 rotates, the reciprocating screw 11, driven by the fixed plate 9 and the fixed plate 10, revolves synchronously around the rotating shaft 4, thereby driving the rotating plate 8 to rotate together. Simultaneously, the reciprocating screw 11 drives the gear 12 to revolve synchronously around the rotating shaft 4. The gear 12 meshes with the gear ring 13, generating its own rotation under this meshing action. The gear 12 then drives the reciprocating screw 11 to rotate synchronously, causing the rotating plate 8 to rise and fall. Thus, the rotating plate 8 simultaneously rises and falls during its rotation.

[0050] As the rotating plate 8 descends, it causes the sealing plate 27 to move downwards. The sealing plate 27, through the sliding frame 29, drives the sliding column 30 to move along the vertical groove 31. At this time, the guide hole 28 on the sealing plate 27 is aligned and connected with the guide cylinder 23, ensuring that the water flows smoothly into the guide cylinder 23. The water flows upwards through the guide cylinder 23, impacting the blades of the water wheel 21 and driving it to rotate. The water wheel 21 drives the crushing plate 20 to rotate through the rotating rod 19, forming a shearing and impact effect on the drug coagulation in the wastewater, thereby breaking up and crushing the drug coagulation.

[0051] Simultaneously, the liquid medicine in the storage cylinder 14 flows through the cavity 16 into the connecting pipe 17 and the telescopic pipe 18, and then into the flow chamber 25. It is then released outwards through the through holes 26 and 37, allowing the liquid medicine to be continuously and dynamically injected into the wastewater along the trajectory of the rotating rod 19. This facilitates rapid diffusion of the liquid medicine across all levels and areas of the water body. Furthermore, the rotating rod 19 rotates under the drive of the water wheel 21, causing the through hole 26 to rotate. This rotation evenly distributes the liquid medicine into the wastewater, further enhancing the diffusion effect and ensuring a more uniform mixing of the liquid medicine and wastewater. Simultaneously, the convective and eddy diffusion effects generated by the rotating rod 19 driving the crushing plate 20 rapidly expand the diffusion radius of the liquid medicine in the wastewater, further improving diffusion efficiency.

[0052] When the sliding column 30 slides from the vertical groove 31 into the spiral groove 33, the sliding column 30, guided by the spiral groove 33, drives the sliding frame 29 to rotate. The sliding frame 29 drives the sealing plate 27 to rotate synchronously. The sealing plate 27 causes the guide hole 28 and the guide cylinder 23 to gradually misalign until the sliding column 30 enters the vertical groove 32. The guide hole 28 and the guide cylinder 23 are completely misaligned, and the sealing plate 27 seals the guide cylinder 23, thus keeping the wastewater at the bottom of the mixing tank 1 inside the guide cylinder 23. At the same time, the reciprocating screw 11 drives the rotating plate 8 to rise, and the sliding column 30 moves upward along the vertical groove 32, maintaining the sealing state of the sealing plate 27. The guide cylinder 23 then lifts the wastewater from the bottom of the mixing tank 1 to the surface.

[0053] During the upward movement of the rotating plate 8, when the sliding column 30 slides into the spiral groove 34, under the reverse guidance of the spiral groove 34, the sliding frame 29 drives the closed plate 27 to rotate in the opposite direction, and the guide hole 28 and the guide cylinder 23 gradually align. During this process, the wastewater remaining in the guide cylinder 23 flows into the surface water of the mixing tank 1 until the sliding column 30 re-enters the vertical groove 31, and the guide hole 28 and the guide cylinder 23 are completely connected, completing one cycle.

[0054] This cyclic action enables continuous circulation of wastewater from bottom to top within the mixing tank 1, breaking down the mixing barrier between the bottom and surface wastewater, improving the overall mixing efficiency of wastewater and chemical solution, further optimizing reaction uniformity, and enhancing the overall efficiency of wastewater treatment.

[0055] As the sealing plate 27 rotates and gradually seals the guide tube 23, its surface forms a sliding fit with the bottom end of the blocking column 35. The upward movement of the blocking column 35 causes the through hole 2 37 to completely misalign with the through hole 1 26, thereby achieving a seal on the through hole 1 26. This prevents the continuous inflow of liquid medicine after the guide tube 23 is sealed, thus preventing excessively high local concentrations of liquid medicine.

[0056] Thus, when the rotating plate 8 drives the rotating rod 19 to descend, the liquid medicine in the storage cylinder 14 flows into the telescopic pipe 18 through the cavity 16 of the rotating shaft 4, and then into the flow chamber 25 and is released outward. The liquid medicine is dynamically added throughout the entire process along the downward trajectory of the rotating plate 8, which facilitates the rapid diffusion of the liquid medicine in various layers and areas of the water body. At the same time, the water flow drives the water wheel 21 to rotate, and the water wheel 21 drives the crushing plate 20 to rotate. On the one hand, it crushes the drug coagulation in the wastewater, so that the particle size of the crushed coagulation is reduced and the specific surface area is increased, which can make more sufficient contact with the liquid medicine, improve the reaction rate, and prevent the coagulation from clogging the pipe. On the other hand, through the convection diffusion and eddy diffusion effect generated by the crushing plate 20 and the water wheel 21, the diffusion radius of the liquid medicine in the wastewater is rapidly expanded, and through the shearing and stirring action of the crushing plate 20 and the water wheel 21, the micro-mixing of the liquid medicine and the wastewater is strengthened, a homogeneous reaction environment is rapidly formed, and the overall mixing efficiency and reaction uniformity are improved.
