Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1: See attached document Figure 1-5 7-11, The present invention provides a wastewater treatment device for electrolytic copper production, including a treatment tank 1, two shells 2 are fixedly embedded on the top of the treatment tank 1, a reagent tank 3 is fixedly connected to the top of each of the two shells 2, and a reagent outlet pipe 4 is fixedly embedded at the bottom of each of the two reagent tanks 3. Inside the processing box 1, a support rod 5 is fixedly connected. A hollow rotating shaft 6 is embedded in the support rod 5 and the top of the processing box 1. A housing 7 is fixedly connected to both sides of the rotating shaft 6. Three stirring rods 8 are fixedly connected to the front and rear sides of the rotating shaft 6. A motor 9 and a support block 10 are fixedly connected to the top of the processing box 1, with the support block 10 located in front of the motor 9. A rotating shaft 11 is fixedly connected to the output shaft of the motor 9. The rotating shaft 11 passes through the support block 10. A bevel gear 12 is fixedly connected to the front end of the rotating shaft 11. A bevel gear 13 is provided in front of the bevel gear 12 and meshes with it. The bevel gear 13 is fixedly sleeved on the outside of the rotating shaft 6. An auxiliary component is provided on the rotating shaft 6, which is used to disrupt the rotation direction of the wastewater to increase the mixing efficiency of the wastewater and the reagent. Support legs 56 are fixedly connected to the four corners of the bottom of the processing box 1; In this implementation scheme, when treating wastewater, controlling the motor 9 to rotate forward will cause the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the bevel gear 12 to rotate, the rotation of the bevel gear 12 drives the bevel gear 13 to rotate, and the rotation of the bevel gear 13 drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 will cause the auxiliary components and multiple stirring rods 8 to rotate. Since the chemicals in the chemical tank 3 can fall into the treatment tank 1 through the chemical outlet pipe 4, the rotation of the stirring rods 8 can stir and mix the wastewater and chemicals. When the stirring rods 8 stir the wastewater, the auxiliary components can disrupt the rotation direction of the wastewater, thereby accelerating the mixing of chemicals and wastewater, reducing the time for the chemicals and wastewater to fully mix, and improving the treatment efficiency. Example 2: When treating wastewater, it is necessary to add wastewater to treatment tank 1 and then discharge the wastewater, as shown in the attached document. Figure 1 , 2 4. In another embodiment of the present invention, a water inlet pipe 14 is fixedly embedded at the top of the treatment box 1, a water outlet pipe 15 is fixedly embedded at the bottom of the treatment box 1, a switch valve 16 is provided on the water outlet pipe 15, a rotating shaft 1 6 is connected to the support rod 5 and the treatment box 1 through a sealed bearing, and a rotating shaft 2 11 is connected to the support block 10 through a bearing. In use, wastewater can be added to the treatment tank 1 through the water inlet pipe 14 at the top of the treatment tank 1, and the treated wastewater can be discharged from the treatment tank 1 through the water outlet pipe 15 at the bottom of the treatment tank 1 and the switch valve 16. Example 3: To increase the mixing efficiency of wastewater and reagents, refer to the appendix. Figure 7-11In another embodiment of the present invention, the auxiliary component includes a reciprocating screw 17 and a reciprocating screw 2 18. The inner ends of the reciprocating screw 17 and the reciprocating screw 2 18 are fixedly connected. The reciprocating screw 17 passes through the top of the rotating shaft 6, and the bottom end of the reciprocating screw 2 18 is connected to the bottom end of the rotating shaft 6. A sliding seat 19 for cooperating with both the reciprocating screw 17 and the reciprocating screw 2 18 is sleeved on their exteriors. A support plate 20 is fixedly connected inside each of the two outer shells 7. A rotating shaft 3 21 is embedded in each of the two support plates 20. The two rotating shafts 3 21 pass through the two outer shells 7 respectively, and a stirring rod 22 is fixedly connected to the outer ends of each of the two rotating shafts 3 21. Both reciprocating screw 17 and reciprocating screw 28 are connected to shaft 1 6 via sealed bearings. Shaft 3 21 is connected to housing 7 and support plate 20 via sealed bearings. Stirring rod 3 23 is provided at the top and bottom of both stirring rods 22. Two sliding grooves are provided on both housings 7. Pull rods 24 are fixedly connected to both sides of both sliding seats 19. The four pull rods 24 pass through the four sliding grooves and slide in contact with them, with the ends of the four pull rods 24 fixedly connected to the four stirring rods 3 23. Two flexible rubber sleeves 25 are fixedly connected to both housings 7, and the four flexible rubber sleeves 25 are fixedly fitted onto the four... The pull rod 24 is covered by four through slots. Two first gears 26 are fitted around the outside of each of the two rotating shafts 21. Pull plates 27 are located behind each of the two first gears 26. The two pull plates 27 are fixedly connected to the two pull rods 24 located at the top of the rotating shafts 21. Toothed plates 28 are fixedly connected to the front of each pull plate 27. Torsion springs 29 are fitted around the outside of each of the two rotating shafts 21, with both ends of the torsion springs 29 fixedly connected to the first gear 26 and the support plate 20, respectively. Protrusions 30 are fixedly connected to the inner sides of each of the two support plates 20. Protrusions 31 are fixedly connected to the inner ends of each of the two rotating shafts 21. The two protrusions 31 are respectively connected to the two... The front sides of the protrusions 30 are in contact with each other. The top of the rotating shaft 1 6 is fixedly fitted with a housing 32. The housing 32 is fitted with a rotating shaft 4 33. The rotating shaft 4 33 is fixedly fitted with a bevel gear 34. The bevel gear 34 is provided with a bevel gear 4 35 that meshes with it on one side. The bevel gear 4 35 is fixedly connected to the top of the reciprocating screw 17. A base plate 36 is fixedly connected between the two medicine boxes 3. A bevel gear ring 1 37 is fixedly connected to the top of the base plate 36. A bevel gear 5 38 is provided with a bevel gear 5 that meshes with it on the top of the bevel gear ring 1 37. The bevel gear 5 38 is fixedly fitted with the outside of the rotating shaft 4 33. The rotating shaft 4 33 and the housing 32 are connected by a bearing. In use, the rotation of shaft 16 causes the auxiliary components to rotate as well. This causes bevel gear 538 to move in a circular motion along bevel gear ring 137, which in turn rotates shaft 433. Shaft 433 then rotates bevel gear 34, which in turn rotates bevel gear 435. Bevel gear 435 then rotates reciprocating screws 17 and 2, causing the two sliding seats 19 to move outwards and then inwards. This, in turn, causes the two upper and two lower pull rods 24 to move up and down continuously. This, in turn, causes the four stirring rods 323 to open and close. When the two pull rods 24 move up and down, they can also move the two pull plates 27 up and down, which in turn causes the two toothed plates 28 to move up and down continuously. When the two toothed plates 28 move up and down, they can also mesh with the two first gears 26. When meshing, the two first gears 26 and the two rotating shafts 21 can rotate, which in turn causes the two stirring rods 22 to rotate. When the four stirring rods 23 open and close, the two stirring rods 22 will also rotate. The above actions are achieved when rotating with the rotating shaft 6, which can achieve the effect of turbulence and increase the mixing effect of wastewater and reagent. It is worth noting that when the four stirring rods 23 open outwards, the toothed plate 28 has not yet engaged with the first gear 26. This prevents the stirring rod 22 from rotating when the stirring rod 23 opens to a small distance, thus avoiding collisions. In addition, a torsion spring 29 is designed on the rotating shaft 21. When the toothed plate 28 and the first gear 26 are not meshed, the elastic force of the torsion spring 29 can keep the protrusion 31 on the rotating shaft 21 in contact with the protrusion 30 on the support plate 20, thereby ensuring that the stirring rod 22 is always horizontal and will not be tilted. This also prevents the stirring rod 23 from not being able to overlap with the stirring rod 22. Example 4: To achieve intermittent addition of the agent and avoid excessive waste or side effects caused by excessively high local concentrations due to continuous addition, please refer to the appendix. Figure 2-3In another embodiment of the present invention, 6, 12-13, a circular plate 39 is sleeved on the outside of the rotating shaft 6. The circular plate 39 is connected to the rotating shaft 6 via a one-way bearing. An arc-shaped conical gear ring 40 is fixedly connected to the top of the circular plate 39. Opening and closing components are provided on both sides of the circular plate 39, which are used to allow the medicine to flow intermittently from the medicine tank 3. The opening and closing components include a connecting rod 41, which is fixedly embedded in the housing 2. Two bent rods 42 are sleeved on the connecting rod 41 and are connected to the connecting rod 41 via bearings. A rotating plate 43 is fixedly connected to the bottom end of the two bent rods 42. A sealing plug 44 is fixedly connected to the top of the rotating plate 43. The sealing plug 44 fills the bottom end of the medicine outlet tube 4. Two torsion springs 45 are sleeved on the outside of the connecting rod 41. The outer ends of the two torsion springs 45 are fixedly connected to the inner walls of the front and rear sides of the housing 2, respectively. The inner ends of the two torsion springs 45 are fixedly connected to the two bent rods 42, respectively. The outer side of the rod 42 is fixedly connected. Both bent rods 42 are provided with sliding grooves. A connecting block 46 is fixedly connected to one side of the medicine box 3. A rotating shaft 47 is embedded in the connecting block 46 and the rotating shaft 47 is connected to the connecting block 46 through a bearing. A turntable 48 is fixedly connected to one end of the rotating shaft 47. A T-shaped rod 49 is provided between the two bent rods 42. Sliding rods 50 are fixedly connected to both the front and rear sides of the T-shaped rod 49. The two sliding rods 50 pass through the two sliding grooves and slide in contact with them. A connecting rod 51 is fixedly connected to one side of the turntable 48. A connecting rod 52 is fixedly embedded in the T-shaped rod 49. A connecting plate 53 is sleeved on the outside of the connecting rods 51 and 52. The connecting plate 53 is connected to the connecting rods 51 and 52 through a bearing. A positioning block 54 is slidably sleeved on the T-shaped rod 49. The positioning block 54 is fixedly connected to the housing 2. A bevel gear 55 is fixedly connected to the other end of the rotating shaft 47. When in use, the rotating shaft 6 can rotate the circular plate 39 together, which in turn drives the bevel gear ring 40 to rotate. When the bevel gear ring 40 rotates, it will mesh with the bevel gear 55 in the two opening and closing components. Since the two opening and closing components work on the same principle, we will take one as an example. When bevel gear ring 2 40 meshes with bevel gear 6 55, bevel gear 6 55 will rotate half a turn, thereby driving rotating shaft 5 47 to rotate and turntable 48 to rotate half a turn. Since connecting plate 53 is connected to connecting rod 1 51 and connecting rod 2 52 through bearings, they can move. Thus, under the action of connecting plate 53, the rotation of turntable 48 can pull T-shaped rod 49 upward. Since the two sliding rods 50 pass through the sliding grooves on the two bent rods 42, when T-shaped rod 49 moves upward, it can make the two bent rods 42 rotate about connecting rod 41 as the rotation axis. This can not only make the two torsion springs 2 45 elastically deform, but also make rotating plate 43 and sealing plug 44 rotate. This can release the blockage of the medicine outlet pipe 4, and then the medicine in medicine tank 3 can flow into treatment tank 1 through medicine outlet pipe 4. When the bevel gear ring 2 40 and the bevel gear 6 55 are not engaged, the two torsion springs 2 45 will rebound, and then the two bent rods 42, the rotating plate 43 and the sealing plug 44 will rotate back to their original positions. Then the sealing plug 44 will seal the bottom of the drug outlet tube 4 again to prevent the drug from flowing out. In this way, the drug can be added only when the bevel gear ring 2 40 and the bevel gear 6 55 are engaged, and no drug will be added at other times, thus achieving intermittent drug addition. In addition, when no medicine needs to be added, the motor 9 can be reversed to make the shaft 6 rotate, so as to mix the wastewater and the medicine. Since the circular plate 39 is connected to the shaft 6 through a one-way bearing, the circular plate 39 does not rotate when the motor 9 reverses, and the medicine will not be added. Only stirring and mixing will be performed. Furthermore, the control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Moreover, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0022] The above are merely preferred embodiments of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
