DETAILED DESCRIPTION

[0014] The following is combined with Figure 1-3 This application is described in further detail.

[0015] The present application embodiment discloses a lathe cutting fluid recovery and filtration device, referring to Figure 1-3, including a base 1, a funnel 2 and a storage cylinder 46. A container for storing filtered cutting fluid can be placed through the base 1. Support rods 3 are fixedly connected to both ends of the top of the base 1. The opposite sides of the two support rods 3 are fixedly connected to the outer surface of the funnel 2. The two support rods 3 cooperate to support the funnel 2. A first support member 41 is movably placed on the top of the funnel 2. A hemispherical coarse-pore filter screen 42 is fixedly connected to the bottom end of the first support member 41. The first support member 41 can support the hemispherical coarse-pore filter screen 42 on the inner top of the funnel 2. A support ring 43 is fixedly connected to the inner middle of the funnel 2. The top of the ring 43 is movably connected with a second support member 44, and the support ring 43 can support the second support member 44. The bottom end of the second support member 44 is fixedly connected with a hemispherical fine-pore filter 45. The diameter of the hemispherical fine-pore filter 45 is larger than the diameter of the hemispherical coarse-pore filter 42. The second support member 44 can support the hemispherical fine-pore filter 45 in the inner middle part of the funnel 2, and make the hemispherical fine-pore filter 45 located below the hemispherical coarse-pore filter 42. The storage cylinder 46 is fixedly installed at the bottom end of the funnel 2 through a fixing member 5. The fixing member 5 is composed of an external threaded ring 51 and a hexagonal threaded collar 52. The threaded ring 51 is fixedly sleeved on the outer surface of the bottom end of the funnel 2, and the hexagonal threaded ring 52 is fixedly connected to the top of the storage tube 46. The hexagonal threaded ring 52 is threadedly sleeved on the outer surface of the external threaded ring 51, so that the storage tube 46 and the funnel 2 can be fixed to ensure that the storage tube 46 is connected to the funnel 2. The bottom end of the storage tube 46 is bonded with an ultra-fine polypropylene fiber melt-blown cloth 47, and activated carbon particles 48 are placed inside the storage tube 46, and the activated carbon particles 48 are located above the ultra-fine polypropylene fiber melt-blown cloth 47. When the cutting fluid is poured onto the hemispherical coarse-pore filter 42, the hemispherical coarse-pore filter 42 can filter out large particles of impurities in the cutting fluid, and the filtered cutting fluid enters the hemispherical fine-pore filter 45, which is used to further filter out fine particles of impurities in the cutting fluid. The cutting fluid filtered by the hemispherical fine-pore filter 45 enters the storage tube 46 and is adsorbed by the activated carbon particles 48, thereby effectively adsorbing the fine particles and dissolved substances in the cutting fluid. The cutting fluid is then filtered again by the ultra-fine polypropylene fiber melt-blown cloth 47 to further improve the purity of the cutting fluid. Finally, the cutting fluid flows into the container for storing the filtered cutting fluid placed on the base 1 and is recovered.

[0016] Reference Figure 1 and Figure 2A collecting cover 61 is provided at the bottom of the storage cylinder 46, and two fixing rods 62 are fixedly connected to the outer surface of the collecting cover 61. One end of the two fixing rods 62 is fixedly connected to the middle part of the opposite side of the two support rods 3 respectively, and the two fixing rods 62 cooperate to support the collecting cover 61. The collecting cover 61 can collect and converge the cutting fluid filtered by the ultra-fine polypropylene fiber melt-blown cloth 47 and discharge it into the container for receiving the filtered cutting fluid placed on the base 1, so as to prevent the cutting fluid from flowing through the edge of the ultra-fine polypropylene fiber melt-blown cloth 47 to the outside of the container for receiving the filtered cutting fluid placed on the base 1.

[0017] Reference Figure 2 and Figure 3 Both ends of the top of the first support member 41 and the two ends of the top of the second support member 44 are fixedly connected with handles 7. Holding the handles 7 on the first support member 41 and the handles 7 on the second support member 44 makes it easy to take the hemispherical coarse-pore filter 42 and the hemispherical fine-pore filter 45 out of the funnel 2, and then deal with the impurities inside them.

[0018] The implementation principle of a lathe cutting fluid recovery and filtering device in an embodiment of the present application is as follows: when in use, the cutting fluid to be filtered is discharged into the hemispherical coarse-pore filter 42, which can filter out large particles of impurities in the cutting fluid, and the filtered cutting fluid enters the hemispherical fine-pore filter 45, which is used to further filter out fine particles of impurities in the cutting fluid. The cutting fluid filtered by the hemispherical fine-pore filter 45 enters the storage tube 46 and is adsorbed by the activated carbon particles 48, thereby effectively adsorbing the fine particles and dissolved substances in the cutting fluid. Subsequently, the cutting fluid is filtered by the ultrafine polypropylene fiber melt-blown cloth 47 to further improve the purity of the cutting fluid. Finally, the cutting fluid flows into the container for storing the filtered cutting fluid placed on the base 1 and is recovered.
