Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing technology, specifically to a wastewater treatment device for bearing manufacturing. Background Technology

[0002] Bearings are core components of mechanical equipment, widely used in intelligent manufacturing, automobile manufacturing, precision instruments, aerospace and other fields, providing important support for the high-quality development of the equipment manufacturing industry. In the large-scale production of bearings, core processes such as grinding, cleaning, quenching and polishing generate a large amount of industrial wastewater, which must be treated by specialized wastewater treatment equipment to meet standards before being discharged.

[0003] While existing wastewater treatment equipment can perform conventional purification of bearing production wastewater, the wastewater generated during bearing production has a complex composition, containing large amounts of emulsified cutting fluid, lubricating oil, metal shavings, and surfactants. The high degree of emulsification and tight oil-water binding make effective separation difficult with conventional sedimentation. Demulsifiers must be added along with thorough agitation to break the emulsion and achieve oil-water separation. However, the agitation mechanism of traditional treatment equipment has significant shortcomings in actual operation. As the demulsification reaction continues, the emulsions in the wastewater gradually destabilize and coagulate, the water viscosity increases, and flocculent aggregates proliferate. The rotational resistance of the agitator continuously increases, especially in the later stages of treatment, leading to a decrease in agitation speed, a weakening of the flow field around the blades, and the emergence of agitation blind zones and dead zones. This makes it difficult for the demulsifier to mix thoroughly with the wastewater, resulting in incomplete demulsification and a significant decrease in oil-water separation efficiency. Ultimately, this leads to unstable effluent quality and reduced treatment efficiency, failing to meet the standards for bearing production wastewater treatment and thus resulting in unsatisfactory treatment performance.

[0004] Therefore, it is necessary to invent a wastewater treatment device for bearing production to solve the above problems. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 This embodiment provides a wastewater treatment device for bearing manufacturing; Please see Figures 1-8As shown, the device includes a frame 1, a pretreatment tank 2 on the upper side of the frame 1, several coarse filter holes 3 on one side of the pretreatment tank 2, a sealing plate 4 slidably connected to the opening of the pretreatment tank 2, a frame groove 5 in the middle of the frame 1, an inlet pipe 6 fixed to one side of the upper end of the frame 1, an outlet pipe 7 fixed to the middle of the lower end of the frame 1, a drive motor 8 fixed to the middle of the upper end of the frame 1, a fixed rod 9 fixed to the drive end of the drive motor 8, and a connecting structure at the other end of the fixed rod 9. The connecting structure includes a fixed frame 11, support frames 12 fixed to both ends of the fixed frame 11, a rotatably connected stabilizing frame 13 to the outer surface of the support frame 12, an internal gear ring 14 fixed to the upper side of the stabilizing frame 13, an external gear ring 15 fixed to the lower side of the stabilizing frame 13, several fine filter holes 16 in the middle of the stabilizing frame 13, a slider 17 slidably connected to the inner wall of one side of the support frame 12, a first spring 18 fixed to one side of the slider 17, and a rotatably connected stabilizing frame 17 to the middle of one side of the slider 17. The device has a rotating rod 19, with a first gear 20 fixed to its lower side and a second gear 21 fixed to its lower end. Several stirring blades 22 are fixed to the upper side of the rotating rod 19. Through the aforementioned gear meshing and switching and speed adaptive adjustment structure, the stirring blades 22 can achieve adaptive dynamic stirring. When the resistance is low, the stirring is slow and gentle; when the resistance is high, the stirring is fast and strong. This ensures that the demulsifier and wastewater are always fully mixed, the demulsification reaction is thorough, the oil and water phases are clearly separated, and the destabilized emulsion fully aggregates and floats to form a stable floating oil layer, which is convenient for subsequent collection and separation. The oil content and suspended solids content in the water are significantly reduced. Ultimately, the effluent quality of the entire treatment device is stable and meets the standards, and the treatment efficiency is continuously controllable. It can adapt to bearing production wastewater of different concentrations and different emulsification degrees, has strong resistance to load fluctuations, and does not require frequent shutdowns for cleaning and manual intervention, thus meeting the standard discharge treatment requirements for bearing production wastewater.

[0021] Please refer to it again. Figures 1-8As shown, the middle of the fixing frame 11 is fixed to the lower end of the fixing rod 9, which passes through the middle of the upper side of the frame 1. The upper side of the fixing rod 9 is fixed to the middle of the cleaning frame 10. The outer surface of the cleaning frame 10 is slidably connected to the inner wall of the pretreatment tank 2. Several coarse filter holes 3 connect the pretreatment tank 2 and the frame groove 5. The liquid inlet pipe 6 is connected to the pretreatment tank 2, and the liquid outlet pipe 7 is connected to the frame groove 5. The outer surface of the sealing plate 4 is in contact with the inner wall of the pretreatment tank 2. The pretreatment tank 2 has a T-shaped cross-section. The two ends of the fixing frame 11 are fixed to the inner walls of the two sides of the support frame 12. The cross-section of the support frame 12 is circular. The outer surface of the support frame 12 is rotatably connected to the inner wall of the stabilizing frame 13. The side of the stabilizing frame 13 is fixed to the inner wall of the frame groove 5. The outer side of the internal gear ring 14 is fixed to the inner wall of the side of the stabilizing frame 13. The lower end of the external gear ring 15 is fixed to the inner wall of the lower end of the stabilizing frame 13. Several fine filter holes 16 pass through the stabilizing frame. In the middle of section 13, the diameter of each fine filter hole 16 is smaller than that of each coarse filter hole 3. The outer surface of the slider 17 is slidably connected to the inner wall of one side of the support frame 12. The vertical cross-section of the slider 17 is L-shaped. One side of the slider 17 is fixed to one end of the first spring 18, and the other end of the first spring 18 is fixed to the inner wall of one side of the support frame 12. The outer surface of the rotating rod 19 is rotatably connected to the middle of one side of the slider 17. The lower side of the rotating rod 19 is fixed to the middle of the first gear 20. The first gear 20 is intermittently meshed with the internal gear ring 14. The lower end of the rotating rod 19 is fixed to the middle of the second gear 21. The second gear 21 is intermittently meshed with the external gear ring 15. The rotation speed of the first gear 20 in the meshing state is lower than that of the second gear 21 in the meshing state. Several stirring blades 22 are fixed to the upper side of the rotating rod 19 in the middle. The cross-section of each stirring blade 22 is cross-shaped.

[0022] The specific implementation process is as follows: First, the inlet pipe 6 introduces bearing production wastewater into the pretreatment tank 2. The wastewater passes through several coarse filter holes 3 in the pretreatment tank 2 to filter out larger impurities. The filtered wastewater then enters the frame tank 5 through the coarse filter holes 3 until the water level in the frame tank 5 rises to cover the top stirring blade 22. At this time, the drive motor 8 drives the fixed rod 9 to rotate, causing the cleaning frame 10 fixed to the upper side of the fixed rod 9 to rotate synchronously. The rotating cleaning frame 10 cleans the larger impurities clogging the coarse filter holes 3 and throws them to one side of the pretreatment tank 2 by centrifugal force. Subsequently, the sealing plate 4 is opened periodically to clean this part of the filtered material. At the same time, the fixed frame 11 fixed to the lower end of the fixed rod 9 rotates synchronously. The rotating fixed frame 11 drives the support frames 12 fixed at both ends to rotate. The rotating support frames 12 rotate along the inner wall of the stabilizing frame 13 fixed to the inner wall of the frame tank 5. At this time, the fixed rod 9 rotates at its highest speed, generating the greatest centrifugal force. This causes the slider 17, which is slidably connected to the inner wall of one side of the support frame 12, to overcome the elastic force of the first spring 18 connected to it and to squeeze the first spring 18. This causes the slider 17 to move synchronously with the rotating rod 19, which is rotatably connected to the middle of one side. The first gear 20 fixed on the lower side of the moving rotating rod 19 approaches the internal gear ring 14 fixed to the side wall of the stabilizer 13 and gradually meshes with it. This causes the rotating rod 19 to rotate on its own axis while revolving around the fixed rod 9, under the meshing action of the first gear 20 and the internal gear ring 14. At this time, it is in a slow rotation state, which makes the several stirring blades 22 fixed on the upper side of the rotating rod 19 rotate slowly in sync with it, and to perform demulsification treatment in conjunction with the added demulsifier. At the same time, the valve of the liquid outlet pipe 7 is opened, and the wastewater after demulsification is discharged from the liquid outlet pipe 7, while the liquid inlet pipe 6 continuously injects wastewater. At this time, the water level in the rack 5 is stable at the position of submerging the highest stirring blade 22. As the amount of emulsion increases, the resistance experienced by the stirring blades 22 increases, causing the rotational speed of the fixed rod 9 to decrease. This causes the elastic force generated by the previously compressed first spring 18 to reset the slider 17. The reset slider 17 then drives the second gear 21, fixed at the lower end of the rotating rod 19, to approach and gradually mesh with the outer gear ring 15, which is fixed to the lower inner wall of the stabilizer 13. Since the second gear 21 has fewer teeth than the first gear 20, and the second gear 21 and the outer gear ring 15 are externally meshed, while the first gear 20 and the inner gear ring 14 are internally meshed, the transmission ratios of the two meshing pairs are different. This results in the second gear 21 rotating at a higher speed than the first gear 20 in the meshing state. Consequently, the rotating rod 19 drives the fixed stirring blades 22 to rotate faster, effectively demulsifying the wastewater in conjunction with the demulsifier. After demulsification is complete, the resistance decreases and the rotation speed increases. It then switches back to slow-speed rotation and stirring to achieve an adaptive dynamic stirring effect. The demulsification reaction is thorough, the oil and water phases are clearly separated, and the destabilized emulsion fully aggregates and floats to the surface, forming a stable floating oil layer, which is convenient for subsequent collection and separation. The oil content and suspended solids content in the water are significantly reduced. Ultimately, the effluent quality of the entire treatment unit is stable and meets the standards, and the treatment efficiency is continuously controllable. It can adapt to bearing production wastewater of different concentrations and different degrees of emulsification, has strong resistance to load fluctuations, meets the standard discharge treatment requirements for bearing production wastewater, and thus improves the overall performance of the treatment unit.

[0023] Example 2 Traditional treatment devices often use a one-time centralized addition method when adding demulsifiers. After the agent enters the water body instantly, it is difficult to disperse quickly and evenly, which can easily lead to excessively high concentrations in some areas and insufficient agent in other areas. This results in incomplete demulsification reaction, poor oil-water separation effect, and also waste of agent and increased treatment costs. Therefore, it is necessary to control and regulate the addition process of demulsifiers in stages so that the agent can participate in the reaction in a sequential and even manner, thereby improving the demulsification efficiency of the treatment device and the quality of the effluent.

[0024] Please see Figures 1-8 As shown, an intermittent controlled feeding function has been added based on Embodiment 1; Please refer to it again. Figures 1-8 As shown, a support block 23 is fixed to the upper side of the fixed rod 9, and a fixed ring 24 is fixed to the other end of the support block 23. A through hole 25 is opened on one side of the fixed ring 24. A hopper 26 is opened on the other side of the upper end of the frame 1. One end of the support block 23 is fixed to the upper side of the fixed rod 9. The support block 23 is set below the cleaning frame 10. The outer surface of the support block 23 is slidably connected to the inner wall of the upper side of the frame groove 5. The other end of the support block 23 is fixed to one side of the fixed ring 24. The cross-section of the fixed ring 24 is circular. The outer surface of the fixed ring 24 is slidably connected to the inner wall of the frame groove 5. The through hole 25 passes through one side of the fixed ring 24. The outer surface of the fixed ring 24 is slidably connected to the discharge port of the hopper 26. The through hole 25 is set below the discharge port of the hopper 26.

[0025] The specific implementation process is as follows: The fixed rod 9 is driven by the drive motor 8 to rotate, so that the support block 23 fixed on the upper side of the fixed rod 9 rotates synchronously. The rotating support block 23 drives the fixed ring 24 fixed at the other end to rotate together. A through hole 25 is opened on one side of the fixed ring 24. When the through hole 25 rotates to the bottom of the hopper 26 opened on the side of the frame 1, the demulsifier in the hopper 26 falls into the frame groove 5. When the rest of the fixed ring 24 rotates to the bottom of the discharge port of the hopper 26, the hopper 26 is blocked. At this time, the demulsifier stops feeding, realizing the effect of intermittent controlled feeding. The addition process of the demulsifier is controlled and controlled step by step, so that the agent can be added to the wastewater in sequence and evenly and participate in the reaction. This avoids problems such as excessive local concentration and uneven mixing caused by concentrated addition at one time, thereby improving the demulsification efficiency of the treatment device and the quality of the effluent.

[0026] Example 3 In traditional treatment systems, after the demulsification reaction, the destabilized and coagulated emulsion rises to the surface, forming an oil slick. This typically requires periodic shutdowns and manual removal. If not cleaned promptly, the oil slick will thicken, overflow, or re-enter the water, affecting effluent quality and interfering with agitation and settling processes, thus hindering continuous and stable operation. Therefore, a flow-guiding and automatic collection structure is needed to continuously collect the floating emulsion, allowing it to flow into a collection area. Only periodic centralized removal of the collected material is required, eliminating the need for system shutdown and thus improving the continuity of operation and overall treatment efficiency.

[0027] Please see Figures 1-8 As shown, the automatic cleaning and convenient collection functions have been added based on Embodiment 1; Please refer to it again. Figures 1-8 As shown, a pressing rod 27 is fixed to one side of the support block 23, and a sliding groove 28 is provided on one side of the frame 1. A sliding frame 29 is slidably connected to the inner wall of the sliding groove 28. A second spring 30 is fixed to one end of the sliding frame 29. A collection groove 31 is provided at the lower end of the sliding groove 28. Several through holes 32 are provided at the lower end of the collection groove 31. A closing frame 33 is detachably installed on one side of the inner wall of the collection groove 31 by bolts. The upper end of the pressing rod 27 is fixed to one side of the support block 23, and the outer surface of the pressing rod 27 is flush with one side of the sliding frame 29. The outer surfaces are in contact with each other. The cross-section of the sliding frame 29 is U-shaped. The outer surface of the sliding frame 29 is slidably connected to the inner wall of the slide groove 28. One end of the second spring 30 is fixed to the middle of one side of the sliding frame 29, and the other end of the second spring 30 is fixed to the inner wall of one end of the slide groove 28. The upper end of the collection groove 31 passes through the middle of the slide groove 28. Several through holes 32 connect the collection groove 31 and the frame groove 5. The four corners of the closed frame 33 are detachably installed at the opening of the collection groove 31 by bolts. The collection groove 31 passes through one side of the frame body 1.

[0028] The specific implementation process is as follows: The fixed rod 9 is driven by the drive motor 8 to rotate, so that the support block 23 fixed on the upper side of the fixed rod 9 rotates synchronously. The rotating support block 23 drives the extrusion rod 27 fixed on the other side to rotate together. During the rotation, the rotating extrusion rod 27 contacts the sliding frame 29 and pushes and extrudes the sliding frame 29, so that the sliding frame 29 slides under the limitation of the inner wall of the slide groove 28 opened on one side of the frame body 1. The sliding frame 29 extrudes the second spring 30 fixed at the other end. At the same time, the opening side of the sliding frame 29 pushes the floating oil at the liquid surface, which is level with the height of the slide groove 28, towards the side of the slide groove 28, so that the floating oil enters the slide groove 28 and falls into the collection tank 31 opened on the lower side of the slide groove 28 under the continuous push. At this time, the floating oil is retained in the collection tank 31, and the wastewater can flow back to the frame trough 5 through several through holes 32 opened on the lower side of the collection tank 31. As the extrusion rod 27 continues to rotate and moves away from the sliding frame 29, the sliding frame 29 resets under the elastic force of the compressed second spring 30. Meanwhile, the revolution direction of the stirring blade 22 faces the opening side of the sliding frame 29, causing the remaining floating oil to continuously flow into the enclosed area of ​​the sliding frame 29, achieving continuous automatic collection. Subsequently, by loosening the bolts to disassemble and open the closed frame 33, the floating oil retained in the collection tank 31 can be cleaned, achieving automatic cleaning and convenient collection. By setting a guiding and automatic collection structure for the floating emulsion, the floating oil can continuously flow into the collection area, requiring only periodic centralized removal of the collected material without requiring a complete machine shutdown for cleaning, thereby improving the operational continuity and overall processing efficiency of the treatment device.
