Description

Technical Field

[0001] This invention relates to the field of filtration and separation technology, and in particular to a magnesium alloy processing equipment with a cutting fluid monitoring and filtration and separation structure. Background Technology

[0002] Magnesium alloys are widely used in the automotive, electronics, and aerospace industries due to their lightweight, high strength, and excellent damping properties. When machining magnesium alloys, cutting fluid not only plays a role in cooling, lubrication, and chip removal, but is also a key medium that prevents magnesium chips from burning and ensures the safety of the machining process by isolating oxygen and cooling. The cleanliness, physicochemical properties, and circulation filtration effect of the cutting fluid directly affect production safety and machining quality.

[0003] Existing cutting fluid circulation structures in magnesium alloy machining equipment mostly employ traditional methods such as filters, magnetic separation, or gravity sedimentation to achieve solid-liquid separation. These methods generally suffer from untimely monitoring and difficulty in flexibly adjusting the filtration structure according to the actual state of the cutting fluid. Consequently, the filtration and separation effect of the cutting fluid is affected. Once the cutting fluid deteriorates, its cooling and lubrication effects will decrease significantly. Furthermore, with existing structures, it is difficult to filter and separate the flammable aerosol mixture formed by the vaporization of cutting fluid and the mixing of cutting chips above the worktable. This results in a significant decrease in the flame retardant performance of the entire cutting fluid circulation system, which easily poses a risk of combustion and explosion, seriously threatening production safety and stability.

[0004] Therefore, a magnesium alloy processing equipment with a cutting fluid monitoring and filtration separation structure is proposed to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by installing the filtration tank on one side of the immersion tank and forming a vertically downward liquid curtain inside the filtration tank through the overflow trough, and cooperating with the fan to drive the cutting fluid aerosol generated above the filtration tank through the liquid curtain, the aerosol impurities can be filtered and separated, which can effectively improve the safety and stability of the equipment during operation. At the same time, by setting up an immersion tank to immerse the magnesium alloy in the cutting fluid for processing, and cooperating with various sensors such as liquid level, viscosity, acid value, particle counter, and moisture in the immersion tank, a system can be constructed to monitor the cutting fluid status in real time and adjust the filtration and separation effect accordingly.

Combined with real-time monitoring by an oil mist concentration sensor, this allows for flexible adjustment of the distance between the two liquid curtains based on the concentration of the combustible aerosol formed by the vaporization of cutting fluid and the mixing of magnesium shavings. This enables flexible adjustment of the filtration and separation effect. Simultaneously, the uniform dispersion of airflow by the filter plate and the staggered guidance of the flow guide allow the aerosol-laden airflow to traverse the dual liquid curtains in a Z-shape, significantly extending the contact time and path between the aerosol and the liquid. This significantly improves the liquid curtain's capture efficiency for fine particles and oil mist, thereby enhancing the filtration and separation effect. 3. In this invention, by setting multiple inclined plates in the settling tank, the settling of large particles of impurities in the cutting fluid can be effectively accelerated. Then, a bag filter is used to achieve fine filtration of the subsequent cutting fluid. With the cooperation of the settling tank and the bag filter, multi-stage filtration of the cutting fluid can be achieved, which is beneficial to improving the efficiency of the cutting fluid circulation filtration. At the same time, by filling the delivery pipe and the temporary storage tank with inert gas and using the isolation discharge component to achieve the safe discharge of magnesium chips in an oxygen-free environment, the risk of spontaneous combustion of magnesium chips upon contact with air can be effectively isolated, which is beneficial to further improving the efficiency and safety of the equipment in filtering and separating cutting fluid.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example: This example provides a magnesium alloy machining equipment with a cutting fluid monitoring and filtration separation structure. See [link to example]. Figure 1 - Figure 12 Specifically, it includes the main body of the equipment 1, an equipment platform 11 is fixedly installed inside the main body of the equipment 1, a workbench 12 is fixedly installed on the equipment platform 11, an immersion tank 2 is fixedly installed on the equipment platform 11 surrounding the outside of the workbench 12, and a liquid level sensor, a viscosity sensor, an acid value sensor, a particle counter and a moisture sensor are fixedly installed inside the immersion tank 2.

[0021] An air blowing box 21 is fixedly installed on one side of the immersion tank 2, and a leaching box 22 is fixedly installed on the other side of the immersion tank 2. A sensor for monitoring aerosol concentration is fixedly installed inside the leaching box 22; this sensor can be a laser scattering dust sensor or an oil mist concentration sensor. A vertically arranged first partition 23 is fixedly installed inside the leaching box 22 near the air blowing box 21, and an air inlet 24 is provided on the first partition 23. A vertically arranged second partition 25 is fixedly installed inside the leaching box 22, and a [missing information - likely a design feature] is provided on the second partition 25. An air outlet 26 is provided. A negative pressure chamber 27 is formed on the side of the filter box 22 away from the air inlet 24, in conjunction with the second partition 25. The lower ends of the first partition 23 and the second partition 25 are inserted into the cutting fluid in the immersion tank 2. An overflow trough 3 is provided at the upper position inside the filter box 22, and an overflow port 31 is provided on the side of the overflow trough 3. The overflow port 31 is located between the second partition 25 and the air outlet 26. A blower 5 is externally connected to the air blowing box 21. The air blowing box 21 is connected to the air outlet of the blower 5, and the negative pressure chamber 27 is connected to the air inlet of the blower 5.

[0022] The main body of the equipment 1 is fixedly installed with a sedimentation tank 6 that is connected to the bottom of the immersion tank 2, a bag filter 8 connected to the sedimentation tank 6, and a storage tank 81 connected to the bag filter 8. An oil pump is fixedly installed in the main body of the equipment 1. The oil pump continuously delivers the cutting fluid in the storage tank 81 to the overflow tank 3. The cutting fluid overflows from the overflow port 31 to form a vertical downward liquid curtain.

[0023] In this equipment, the magnesium alloy is firmly installed on the worktable 12 during operation. During the turning process, the magnesium alloy is completely immersed in the cutting fluid in the immersion tank 2. The cutting fluid is anhydrous. The level sensor installed in the immersion tank 2 can monitor the level of the cutting fluid in real time. By immersing the magnesium alloy in the cutting fluid, rapid heat dissipation can be achieved, and oxygen isolation can be achieved, which effectively reduces the probability of fire during the processing of magnesium alloy.

[0024] During operation, fan 5 starts, and airflow is blown out from air box 21 to... Figure 4 With the structural orientation as a reference, the airflow is blown horizontally from right to left across the working area above the immersion tank 2, carrying the high-temperature aerosol mixture generated during processing towards the filtration box 22. The airflow carrying the aerosol enters through the air inlet 24. At the same time, the oil pump pumps the cutting fluid purified by the bag filter 8 in the storage tank 81 into the overflow tank 3. The cutting fluid overflows steadily through the overflow port 31, forming a vertical liquid curtain. When the aerosol entering the filtration box 22 passes through the liquid curtain, most of the particles and oil droplets inside are captured by the vertically flushed liquid curtain. The purified air enters the negative pressure chamber 27 through the air outlet 26 and is finally drawn away by the fan 5, realizing the circulation filtration and separation of the cutting fluid aerosol.

[0025] In this device, an electrically controlled valve is installed between the immersion tank 2 and the sedimentation tank 6. Under the monitoring of the liquid level sensor, the depth of the cutting fluid in the immersion tank 2 can be flexibly adjusted by controlling the flow rate of the liquid curtain and the opening of the electrically controlled valve. The connection between the immersion tank 2 and the sedimentation tank 6 is set at the bottom right end of the immersion tank 2, which allows the cutting fluid in the immersion tank 2 to flow from left to right. During the circulation process, the magnesium alloy processing area can be thoroughly flushed, which facilitates the timely removal of chips and high temperatures generated during cutting.

[0026] Therefore, the viscosity sensor, acid value sensor, particle counter, and moisture sensor are installed at the right end of the immersion tank 2. Through the cooperation of the viscosity sensor, acid value sensor, particle counter, and moisture sensor, the actual state of the cutting fluid in the immersion tank 2 after use can be monitored in real time. This facilitates flexible control of the flow rate and filtration efficiency of the subsequent settling tank 6 and bag filter 8 through the analysis of the cutting fluid state. The cooperation of the settling tank 6 and bag filter 8 achieves multi-stage filtration, which can prevent magnesium alloy debris from remaining in the cutting fluid for a long time and causing pollution to the cutting fluid.

[0027] In the specific implementation process, such as Figure 4 , Figure 6 and Figure 7 As shown, there are two overflow channels 3, with overflow ports 31 facing each other. The two liquid curtains formed at the two overflow ports 31 are separated between the air inlet 24 and the air outlet 26. A linear guide 32 is fixedly installed at the top of the filter box 22, and a slider 33 is slidably connected to the linear guide 32. The overflow channels 3 are fixedly connected to the corresponding sliders 33. A bidirectional screw 34 is rotatably installed in the filter box 22, parallel to the linear guide 32, and both ends of the bidirectional screw 34 are threaded with sleeves 35. The overflow channels 3 are fixedly connected to the corresponding sleeves 35. A first servo motor 36 for driving the bidirectional screw 34 to rotate is fixedly installed in the filter box 22. In this device, by setting two overflow channels 3, and with the help of the two parallel vertical liquid curtains flowing out of the overflow ports 31 on the two overflow channels 3, a double liquid curtain filtration and separation mode can be realized, which effectively improves the effect of the device in filtering and separating aerosols in the airflow.

[0028] In the process of using a dual liquid curtain to filter and separate cutting fluid aerosols, the airflow passes through the two liquid curtains sequentially. Since the distance between the two overflow channels 3 can be flexibly adjusted, the distance between the two liquid curtains can be adjusted according to actual needs. During the adjustment process, the first servo motor 36 drives the bidirectional screw 34 to rotate, which can drive the two screw sleeves 35 to move in opposite directions, thereby precisely adjusting the distance between the two overflow channels 3 and the liquid curtain in between. When facing a large number of large particles of debris generated during rough machining, the distance between the two liquid curtains can be increased to improve the filtration and separation effect of the dual liquid curtain structure on large particles of debris. When facing a large number of fine dust generated during fine machining, the distance between the two liquid curtains can be decreased to enhance turbulence and secondary collection, thereby improving the removal efficiency of the equipment for fine particles. Through this adaptive adjustment capability, the equipment can maintain the optimal performance state for filtering and separating aerosols.

[0029] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, a first guide hood 4 pointing towards the liquid curtain is fixedly installed on the air inlet 24, and a second guide hood 41 pointing towards the liquid curtain is fixedly installed on the air outlet 26. The inner diameters of the first guide hood 4 and the second guide hood 41 near the liquid curtain gradually decrease. A first sieve plate 42 is fixedly installed at the air outlet of the air blowing box 21, and a second sieve plate 43 is fixedly covered on the air inlet 24. The first guide hood 4 and the second guide hood 41 are staggered, and the ends of the first guide hood 4 and the second guide hood 41 near the liquid curtain are offset from each other.

[0030] In this device, when the airflow is blown out from the blowing box 21 to the filtration box 22, it will be diverted through the uniformly distributed through holes on the first screen plate 42. Similarly, when the airflow carrying aerosol enters through the air inlet 24, it will also be diverted through the uniformly distributed through holes on the second screen plate 43. This makes the airflow more uniform and helps to avoid the formation of local high-speed jets impacting the liquid curtain.

[0031] Meanwhile, as the airflow enters through the air inlet 24 and exits through the air outlet 26, the gradually narrowing structure of the first guide hood 4 and the gradually expanding structure of the second guide hood 41 work together to smoothly guide the airflow and concentrate it through the effective area of ​​the liquid curtain. At the same time, by arranging the first guide hood 4 and the second guide hood 41 in an alternating manner, the airflow can be forced to change direction between the two liquid curtains. This not only helps to enhance the travel time of aerosols within the liquid curtain, but also helps to increase the inertial collision between particles and oil in the aerosol and the liquid curtain, thereby improving the interception effect of the liquid curtain and effectively improving the capture efficiency when passing through the liquid curtain.

[0032] In the specific implementation process, such as Figure 2 and Figure 10 As shown, a cyclone separator 51 is fixedly installed inside the main body 1 of the equipment. The air inlet of the cyclone separator 51 is fixedly connected to the inside of the negative pressure chamber 27, and the air outlet of the cyclone separator 51 is fixedly connected to the air inlet of the fan 5. A liquid collection tank 52 is fixedly connected to the lower end of the cyclone separator 51. In this equipment, the airflow after being washed by the liquid curtain may still carry a small amount of liquid droplets. Under the suction of the fan 5, the airflow in the negative pressure chamber 27 enters the cyclone separator 51. Here, the airflow enters tangentially. The high-speed rotation causes droplets and residual fine particles to be thrown against the wall under centrifugal force, sliding down the wall and being collected in the collection tank 52, thus realizing the recovery of cutting fluid. Meanwhile, dry air is extracted from the top outlet by the blower 5, thereby completing the final separation and recovery of liquid components in the aerosol and effectively protecting the blower 5. An oil pump is also installed at the bottom of the collection tank 52, which returns the cutting fluid collected in the collection tank 52 to the immersion tank 2, reducing the loss of cutting fluid.

[0033] In the specific implementation process, such as Figure 2 , Figure 5 and Figure 9 As shown, an inlet pipe 61 connected to the bottom of the immersion tank 2 is fixedly installed at the upper position of one end of the sedimentation tank 6, and an outlet pipe 62 connected to the bag filter 8 is fixedly installed at the upper position of the other end of the sedimentation tank 6. Multiple inclined plates 63 evenly distributed between the inlet pipe 61 and the outlet pipe 62 are fixedly installed inside the sedimentation tank 6. The bottom of the sedimentation tank 6 is configured as a funnel-shaped structure. An inclined upward conveying pipe 64 is fixedly connected to the bottom of the sedimentation tank 6, and the upper end of the conveying pipe 64 extends to the top of the sedimentation tank 6. A spiral conveying roller 65 is rotatably installed inside the conveying pipe 64, and a second servo motor 66 for driving the spiral conveying roller 65 to rotate is fixedly installed on the conveying pipe 64.

[0034] In this device, the used dirty cutting fluid enters the sedimentation tank 6 from the bottom of the immersion tank 2 through the inlet pipe 61. Inside the sedimentation tank 6, the fluid flows from the inlet pipe 61 to the outlet pipe 62. The multi-layer inclined plates 63 inside the sedimentation tank 6 provide a large settling area, allowing heavier solid particles such as magnesium alloy shavings to quickly settle to the bottom of the sedimentation tank 6. The preliminarily clarified cutting fluid overflows from the upper outlet pipe 62 into the subsequent bag filter 8 for fine filtration. During this process, the sludge settled at the bottom of the funnel-shaped tank enters the lower end of the conveying pipe 64. Driven by the second servo motor 66, it is conveyed upward along the inclined conveying pipe 64 by the spiral conveying roller 65. Through the spiral conveying of the spiral conveying roller 65, not only can the solid sludge be continuously discharged, but its sealing structure also effectively prevents air from entering.

[0035] In the specific implementation process, such as Figure 1 , Figure 11 and Figure 12As shown, a temporary storage box 7 is fixedly connected to the upper end of the conveying pipe 64, and a discharge box 71 is installed below the temporary storage box 7. An isolation discharge assembly 72 is installed between the temporary storage box 7 and the discharge box 71. The conveying pipe 64 and the temporary storage box 7 are filled with inert gas. The isolation discharge assembly 72 includes a square tube 721 fixedly connected between the temporary storage box 7 and the discharge box 71. A roller 722 is rotatably installed inside the square tube 721. Multiple evenly distributed partitions 723 are fixedly fixed around the cylindrical surface of the roller 722. A third servo motor 724 for driving the roller 722 to rotate is fixedly installed on the square tube 721. A filling wall 725 that is gathered on both sides of the multiple partitions 723 on the roller 722 is fixedly installed inside the square tube 721.

[0036] In this device, a position sensor is fixedly installed inside the temporary storage box 7. The position sensor is used to detect the height of the magnesium alloy scrap and impurities accumulated in the temporary storage box 7. During operation, the scrap and impurities accumulated in the temporary storage box 7 are controlled to fall into the discharge box 71 by the isolation discharge assembly 72. The isolation discharge assembly 72 is used for the transfer of scrap and impurities. When the third servo motor 724 drives the roller 722 to rotate, the partitions 723 on it scrape the scrap at the bottom of the temporary storage box 7 into the square tube 721 and send it into the discharge box 71. The filling wall 725 is tightly attached to both sides of the rotating part formed by multiple partitions 723 and roller 722, forming a dynamic seal together with the rotating partitions 723. The scrap is transferred by the isolation discharge assembly 72. When debris and impurities are present, the position sensor ensures that the bottom of the temporary storage box 7 is always covered with debris and impurities. During continuous slag discharge, the inert gas environment in the temporary storage box 7 and the conveying pipe 64 is maintained to the maximum extent, reducing the probability of inert gas in the temporary storage box 7 escaping into the discharge box 71 through the isolation discharge component 72. The inert gas can be nitrogen. This inert gas environment can ensure that magnesium chips are isolated from oxygen during the conveying and temporary storage process, fundamentally eliminating the conditions for combustion. After the debris and impurities fall into the discharge box 71 periodically, they need to be cleaned and removed in time. Through the above structural settings, it can be ensured that the magnesium chips are in an oxygen-deficient state throughout the entire process from wet collection and conveying to dry discharge, effectively eliminating the risk of combustion and explosion.

[0037] Specifically, the working principle of this invention is as follows: Magnesium alloy workpieces are machined on worktable 12 and submerged in cutting fluid in immersion tank 2 for cooling and flame protection. The high temperature generated during machining causes some of the cutting fluid to vaporize and mix with magnesium chips to form an aerosol. The monitoring system monitors the status of the cutting fluid in real time through various sensors in immersion tank 2.

[0038] During operation, when separating and filtering the aerosol generated on the cutting fluid, the blower 5 operates, forming a directional airflow between the negative pressure chamber 27 of the blowing box 21 and the filtration box 22, blowing the aerosol towards the double liquid curtain generated by the overflow tank 3. When the particles and oil mist in the aerosol are forced to pass through the double liquid curtain, they are captured and carried away by the cutting fluid. The purified air is further dehumidified by the cyclone separator 51 and then circulated.

[0039] During the circulating filtration and separation of cutting fluid, dirty cutting fluid flows from the immersion tank 2 into the sedimentation tank 6 for primary sedimentation. Solid slag is transported to the temporary storage tank 7 by the screw conveyor roller 65 in an inert environment and safely discharged through the isolation discharge assembly 72. The subsequent cutting fluid is finely filtered by the bag filter 8 and returned to the storage tank 81. Then, the oil pump supplies the overflow tank 3 to form a liquid curtain, constituting a complete closed loop. The entire system can intelligently adjust parameters such as the liquid curtain spacing and the air volume of the fan 5 through sensor data, realizing full-process, integrated intelligent protection for cutting fluid performance, efficient collection of airborne pollutants and safe disposal of solid waste, significantly improving the inherent safety and operational stability of magnesium alloy processing.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
