[0010] Preferably, the oil-water separation device further includes an inclined plate, and the top of the water collection tank is provided with an inclined plate, the bottom of the inclined plate being connected to the top of the U-shaped plate by a fixing rod.

[0011] Preferably, the oil-water separation device further includes an oil delivery pipe, an oil collection tank, and an oil pump. An oil delivery pipe is installed above the inside of the water collection tank. A spiral shaft is rotatably installed inside the oil delivery pipe. The end of the oil delivery pipe away from the water collection tank passes through and is fixedly installed inside the oil collection tank. A heating conduit is fixedly installed inside the oil collection tank. The left side of the oil collection tank is fixedly connected to the right side of the oil pump through an oil pump pipe, and the oil pump pipe passes through the oil collection tank.

[0012] This invention provides a purification device for removing oil mist and water mist from CNC machining centers. It has the following beneficial effects:

[0013] (1) The present invention, through the setting of negative pressure fan, water gun, electric grinding wheel and "T" shaped table, enables the processing cleaning equipment to ensure that water mist is extracted and to ensure good processing visibility; at the same time, it ensures the service life of the cutting head to a certain extent and reduces the need to replace the cutting head; the water flows out through the square hole opened on the baffle plate, and the design of the square hole can make the cutting debris flow away with the clean water and not stay inside the processing cleaning device, so that the processing environment is clean and dry.

[0014] (2) The present invention, through the arrangement of the collection box, filter screen and support rod, can block the falling debris. The support rod around the perimeter can provide good stability for the filter screen and prevent it from shifting due to the impact of the falling water. At the same time, the water will fall to the bottom of the collection box through the circular holes on the filter screen, achieving solid-liquid separation. The roller and cleaning brush can wash away any water stains and waste oil that may remain on the surface of the filter screen. At the same time, the debris will be pushed and cleaned at the same time, so that the filter screen will not accumulate or blockage. To a certain extent, this ensures the work progress and the long-term operation of the processing and sorting device. The vacuum cleaner, air inlet pipe, air outlet pipe and storage box can collect the debris in a centralized manner, which is convenient for subsequent processing personnel to clean up in a centralized manner, saving cleaning time and protecting the health and safety of cleaning personnel to a certain extent.

[0015] (3) The present invention, through the arrangement of the water collection tank, telescopic rod and vibrating block, promotes the separation of oil and water mixture in the processing and sorting device to a certain extent. At the same time, it also has a certain separation effect on the oil and water mixture in the water collection tank, so that the oil rises and the water falls, which facilitates the subsequent oil and water separation processing. Through the arrangement of the U-shaped plate, connecting rod and inclined plate, the floating oil is pushed and gathered towards the center, which makes it easier for the oil pipeline to extract the oil in the water collection tank and transport it to the oil collection tank. Through the arrangement of the oil pump and heating pipe, the oil in the oil collection tank can be centrally extracted and transported to the oil storage tank, which facilitates the subsequent secondary processing or secondary processing, reduces the subsequent cleaning work to a certain extent, and also promotes the secondary utilization of resources, which is more environmentally friendly.

[0023] 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.

[0024] Please see Figure 1-6 The present invention provides a technical solution: a purification device for removing oil mist and water mist in CNC machining centers.

[0025] A CNC machining center oil mist and water mist removal purification device includes a machine tool body 1, an operating system 2 on the front of the machine tool body 1, a machining cleaning device 3, a machining sorting device 4, and an oil-water separation device 5. The machining cleaning device 3 is located inside the machine tool body 1, the machining sorting device 4 is located at the bottom of the machining cleaning device 3, and the oil-water separation device 5 is located at the bottom of the machining sorting device 4. The machining cleaning device 3 includes a cutting device 31, a cutting head 32, and a negative pressure fan 33. The cutting device 31 is located at the upper center inside the machining cleaning device 3, and the cutting head 32 is fixedly installed at the bottom of the cutting device 31. The negative pressure fan 33 is fixedly installed on the right side of the inner wall of the machining cleaning device 3. The system removes any water mist that may be generated during processing to ensure good visibility. A lifting frame is located on the left side of the negative pressure fan 33, and two water guns 34 are fixedly installed on the surface of the lifting frame. An electric grinding wheel 35 is placed between the two water guns 34 to clean any debris that may be present on the cutting head 32. The electric grinding wheel 35 grinds the cutting head 32 to prevent it from becoming dull after prolonged use, thus ensuring processing accuracy and efficiency. A "T"-shaped platform 36 is provided at the bottom of the cutting head 32. A baffle plate 37 is placed between the bottom of the "T"-shaped platform 36 and the bottom of the inner wall of the processing cleaning device 3. The square hole design allows the cutting debris to flow away with the clean water and not remain inside the processing cleaning device 3, making the processing environment clean and dry.

[0026] The processing and sorting device 4 includes a collection box 41, a roller 42, a cleaning brush 43, and a support rod 45. The collection box 41 is located at the bottom of the baffle plate 37. A groove is provided on the inner wall of the collection box 41. The roller 42 is rotatably installed inside the groove. The roller 42 passes through and is fixedly installed at the center of the cleaning brush 43. A filter screen 44 is provided at the bottom of the cleaning brush 43. The support rod 45 is fixedly installed at the bottom of the collection box 41 and passes through the filter screen 44. The filter screen 44 in the collection box 41 will block the falling debris. The support rod 45 around the filter screen 44 can provide good stability for the filter screen 44 and will not shift due to the impact of the falling water. At the same time, water will fall through the circular holes on the filter screen 44 to the bottom of the collection box 41, achieving the effect of solid-liquid separation. The processing and sorting device 4 also includes a vacuum cleaner 46 and an exhaust pipe 48. The vacuum cleaner 46 is fixedly installed on the right side of the front of the collection box 41. An air inlet pipe 47 is fixedly connected to the inside of the vacuum cleaner 46. The right side of the air inlet pipe 47 is fixedly connected to the exhaust pipe 48. The exhaust pipe 48 passes through and is fixedly installed inside the storage box 49. The left side of the storage box 49 is fixedly connected to the collection box 41. The filter screen 44 is located on the movement trajectory of the cleaning brush 43, which is parallel to the air inlet pipe 47. The powerful suction generated by the vacuum cleaner 46 draws debris into the air inlet pipe 47. The debris is then transported to the storage box 49 through the exhaust pipe 48, thus collecting the debris centrally. This facilitates subsequent cleaning by processing personnel, saves cleaning time, and to a certain extent protects the health and safety of cleaning personnel.

[0027] The oil-water separation device 5 includes a water collection tank 51 and a U-shaped plate 52. The U-shaped plate 52 is installed inside the water collection tank 51. A connecting rod 54 is fixedly installed above the surface of the U-shaped plate 52. A telescopic rod 55 is embedded in the top of the connecting rod 54. A vibration device is connected to the telescopic rod 55, and a vibration block 56 is fixedly installed at the top of the telescopic rod 55. A spring is installed between the telescopic rod 55 and the vibration block 56. During the spring's compression deformation, the vibration block 56 continuously collides with the inner wall of the water collection tank 51, generating vibrational force that is transmitted to the processing and sorting device 4, thus promoting the separation of the oil-water mixture in the processing and sorting device 4 to a certain extent. The oil-water separation device 5 also includes an inclined plate 53. An inclined plate 53 is installed at the top of the water collection tank 51, which pushes and gathers the floating oil towards the center. The bottom of the inclined plate 53 is connected to the top of the U-shaped plate 52 by a fixed rod. The oil-water separation device 5 also includes an oil delivery pipe 57, an oil collection tank 59, and an oil pump 502. The oil delivery pipe 57 is installed above the inside of the water collection tank 51. A spiral shaft 58 is rotatably installed inside the oil delivery pipe 57. The end of the oil delivery pipe 57 away from the water collection tank 51 passes through and is fixedly installed inside the oil collection tank 59. A heating pipe 501 is fixedly installed inside the oil collection tank 59. The left side of the oil collection tank 59 is fixedly connected to the right side of the oil pump 502 through an oil extraction pipe, which passes through the oil collection tank 59. The oil collection tank 59 is heated by the heating pipe 501 to further separate oil, water, and debris. After heating, the oil will float to the surface. The oil in the oil collection tank 59 is then concentratedly extracted through the oil extraction pipe in the oil pump 502 and transported to the oil storage tank for subsequent secondary treatment or processing. This reduces the subsequent cleaning work to a certain extent and promotes the secondary utilization of resources, making it more environmentally friendly.

[0028] During use, the machine tool body 1 is controlled by the operating system 2 to perform processing work. The processing and cleaning equipment starts operating, and the cutting device 31 drives the cutting head 32 to descend to the processing position to process the material on the "T"-shaped table 36. The negative pressure fans 33 on both sides start to remove any water mist that may be generated in the processing and cleaning device 3, ensuring a good processing view. After processing, the cutting device 31 drives the cutting head 32 to reset, and the water gun 34 starts spraying water to clean any debris that may be present on the cutting head 32. The electric grinding wheel 35 grinds the cutting head 32 to prevent the cutting blade from slipping. The head 32 becomes dull after long-term use, ensuring processing accuracy and efficiency. At the same time, the brush on the electric grinding wheel 35 will perform secondary cleaning and drying of the cutting head 32, which will ensure the service life of the cutting head 32 to a certain extent and reduce the need to replace the cutting head. The inclined surface around the "T"-shaped platform 36 can better allow the water to flow down after cleaning, ensuring the cleanliness of the processing table. The water flows out through the square holes on the baffle plate 37. At the same time, the design of the square holes can also allow cutting debris to flow away with the clean water, preventing it from remaining inside the processing cleaning device 3, making the processing environment clean and dry.

[0029] The processing and sorting device 4 collects the water and debris flowing out of the baffle plate 37 into the collection box 41. The filter screen 44 in the collection box 41 blocks the falling debris. The support rods 45 around the filter screen 44 provide good stability and prevent it from shifting due to the impact of the falling water. At the same time, the water falls through the circular holes on the filter screen 44 to the bottom of the collection box 41, achieving solid-liquid separation. At this time, the roller 42 in the processing and sorting device 4 starts to rotate. When the roller 42 rotates, it drives the cleaning brush 43 to rotate as well. The roller 42 carries the cleaning brush 43 horizontally along the sliding grooves on both sides. During operation, the filter screen 44 is brushed to remove any remaining water stains and waste oil. At the same time, debris is pushed and cleaned simultaneously, preventing the filter screen 44 from accumulating or becoming clogged. This ensures the smooth operation of the work and allows the processing and sorting device 4 to operate for an extended period. The debris is pushed to the air inlet pipe 47 by the cleaning brush 43. The powerful suction generated by the vacuum cleaner 46 draws the debris into the air inlet pipe 47. The collected debris is then transported to the storage bin 49 through the air outlet pipe 48, thus collecting the debris for subsequent cleaning by the processing personnel. This saves cleaning time and protects the health and safety of the cleaning staff to some extent.

[0030] The oil-water mixture flowing through filter 44 falls into the water collection tank 51 inside the oil-water separator 5. In the water collection tank 51, the telescopic rod 55 reciprocates, causing the spring to compress and deform. During this compression and deformation, the spring drives the vibrating block 56 to continuously collide with the inner wall of the water collection tank 51, generating vibrational force that is transmitted to the processing and sorting device 4. This promotes oil-water separation in the processing and sorting device 4 to a certain extent. Simultaneously, it also has a certain separation effect on the oil-water mixture in the water collection tank 51, causing the oil to rise and the water to fall, facilitating subsequent oil-water separation processing. When the telescopic rod 55 moves horizontally, it drives the guide plate 52 to move horizontally via the connecting rod 54. When the guide plate 52 moves horizontally, it drives the inclined plate 53 to move horizontally via the fixed rod. When the inclined plate 53 moves horizontally, it pushes and gathers the floating oil towards the center, making it easier for the oil pipe 57 to extract and transport the oil from the water collection tank 51 to the oil collection tank 59. The spiral shaft 58 can transport fine debris floating on the oil surface together, which facilitates subsequent cleaning work to a certain extent. The oil is transported to the oil collection tank 59 through the oil pipe 57. The oil collection tank 59 is heated by the heating pipe 501, which further separates the oil, water and debris. After heating, the oil will float to the surface. The oil in the oil collection tank 59 is then concentrated and extracted through the oil extraction pipe in the oil pump 502 and transported to the oil storage tank, which facilitates subsequent secondary treatment or processing. This reduces the subsequent cleaning work to a certain extent and also promotes the secondary use of resources, making it more environmentally friendly.
