Description

Technical Field

[0001] The invention relates to the technical field of cutting fluid recovery equipment, and in particular to a centralized cutting fluid conveying and separation system and method separated from a machine tool. Background Art

[0002] Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded with a variety of super-functional additives, and has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution. It overcomes the problems of traditional soap-based emulsions that are easy to stink in summer, difficult to dilute in winter, and have poor anti-rust effect. It has no adverse effects on lathe paint and is suitable for cutting and grinding of ferrous metals. It is currently the most advanced grinding product. After the cutting work is completed, the discarded cutting fluid is mixed with a large amount of metal scraps. Due to the large amount of cutting fluid used, in order to save production costs, it is often necessary to recycle the used cutting fluid.

[0003] In the prior art, the precipitation and reuse of cutting fluid is mostly achieved through a sedimentation tank, but the sedimentation tank occupies a large area, and the waste chips at the bottom of the sedimentation tank need to be separated and processed for a second time, which is not only time-consuming and labor-intensive, but also has low work efficiency. In addition, when cast iron parts are machined, iron powder with extremely small particle size often mixes into the cutting fluid, and the existing cutting fluid circulation filtration system can only filter out the fine iron powder through a multi-stage filter box, so the iron powder that cannot be completely removed from the cutting fluid will block the pipeline of the cutting fluid reflux pump and affect the reliable reflux of the cutting fluid. On the other hand, the reuse of the recovered cutting fluid will seriously affect the processing quality of the parts. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides four technical solutions:

[0037] like Figure 1-4The first embodiment is shown: a centralized cutting fluid conveying and separation system separated from a machine tool, comprising a separation cylinder 1 and a feeding assembly 2 fixedly connected to the top of the separation cylinder 1 and connected to the interior thereof, and a support frame 3 fixedly sleeved on the outer wall of the feeding assembly 2, the front and rear sides of the outer wall of the separation cylinder 1 are respectively fixedly connected with a first collecting mechanism 4 and a second collecting mechanism 5 by bolts, and the outer wall of the separation cylinder 1 is provided with a lower collecting port 6, an upper collecting port 7 and a long through hole 8 from bottom to top, a cleaning port is provided at the bottom of the separation cylinder 1, a sealing cover plate 9 is connected to the inside of the cleaning port by bolts, a conical block 10 is fixedly connected to the top of the sealing cover plate 9, a collecting tank 11 is provided at the top of the conical block 10, a magnet block is fixedly connected to the bottom of the collecting tank 11, a discharge pipe 12 connected to the interior thereof is fixedly connected to the outer wall of the separation cylinder 1, and the inner wall of the separation cylinder 1 is provided with a plurality of holes 8 from top to bottom. An upper filter assembly 13 and a lower filter assembly 14 are fixedly connected to the bottom, and a second motor 15 is fixedly connected to the top of the separation cylinder 1, the output end of the second motor 15 rotates through the separation cylinder 1 and is fixedly connected to a transmission shaft 16, the bottom end of the transmission shaft 16 rotates through the upper filter assembly 13 and the lower filter assembly 14 and is fixedly connected to a cleaning brush 17, a driving arm 18 is fixedly sleeved on the outer wall of the transmission shaft 16 and located above the upper filter assembly 13, and a driving block 19 is fixedly connected to the side of the bottom of the driving arm 18 away from the transmission shaft 16. Except for the inner diameter of the filter holes on the surface, the upper filter assembly 13 and the lower filter assembly 14 are exactly the same in other structures. The inner diameter of the filter holes on the surface of the lower filter assembly 14 is smaller than the filter holes on the surface of the upper filter assembly 13. The second motor 15 is in a waiting state in step one, and the speed of the second motor 15 is 30r / min when it is working.

[0038] The feeding assembly 2 includes a feeding pipe 21, a feeding hopper 22 fixedly connected to the top of the feeding pipe 21, and a first motor 23 fixedly connected to one end of the feeding pipe 21. The output shaft of the first motor 23 rotates through the feeding pipe 21 and is fixedly connected to an auger 24 through a coupling.

[0039] By setting up two upper filter components 13 and lower filter components 14 with different filtering degrees, larger metal chips are filtered first, and smaller metal chips and cutting fluid fall to the top of the lower filter component 14 through the filter holes on the surface of the upper filter component 13. The filter holes on the surface of the lower filter component 14 are smaller than the inner diameter of the filter holes on the surface of the upper filter component 13, and small metal chips remain on the surface of the lower filter component 14, so that impurities in the cutting fluid can be fully filtered out through multi-stage filtration, thereby improving the separation effect of impurities in the cutting fluid.

[0040] The filtered cutting fluid is discharged through the discharge pipe 12, and the cutting fluid falling on the top of the conical block 10 continuously impacts it, and the finer particles mixed inside are gradually impacted and slide into the collecting tank 11. Since a magnet block is arranged inside the collecting tank 11, the fine slag is adsorbed by it, and the sealing cover plate 9 can be disassembled after the cutting fluid is discharged to clean the fine gold and iron slag, thereby further improving the metal debris separation effect of the cutting fluid.

[0041] like Figure 4-7 A second embodiment is shown, and its main difference from the first embodiment is that the first collecting mechanism 4 and the second collecting mechanism 5 are two components with exactly the same structure. The first collecting mechanism 4 includes a collecting box 41 and a collecting chamber 42 and a first discharge port 43 respectively opened at the top and bottom of the collecting box 41. An upper feed port 44 and a lower feed port 45 are respectively opened on the side wall of the collecting box 41 close to the separation cylinder 1 from top to bottom. A sealing plug 46 is connected to the internal thread of the first discharge port 43, and a hexagonal disassembly hole 47 for disassembly is opened at the bottom of the sealing plug 46. A cover plate 48 is fixedly connected to the interior of the collecting chamber 42, and a compaction assembly 49 is slidably connected to the interior of the collecting chamber 42 and below the cover plate 48.

[0042] like Figure 8-9 A third embodiment is shown, which mainly differs from the second embodiment in that the compacting assembly 49 includes a pressing block 491 and a lifting column 492 fixedly connected to the top of the pressing block 491, and a sleeve 493 slidably sleeved on the outer wall of the lifting column 492, the top of the lifting column 492 is fixedly connected to a limiting disk 494, and a spring 495 is sleeved on the outer wall of the lifting column 492, a spring baffle 496 is fixedly sleeved on the outer wall of the sleeve 493, and a holding arm 497 is fixedly connected to the top of the sleeve 493, and a protrusion 498 is fixedly connected to the end of the holding arm 497 away from the holding arm 497, the limiting disk 494 slides through the cover plate 48 and extends to the outside, and an air hole for exhaust is opened on the top of the limiting disk 494, the holding arm 497 slides through the long through hole 8 and extends to the inside of the separation cylinder 1, and the protrusion 498 is located directly below the driving block 19.

[0043] The second motor 15 rotates to synchronously drive the driving arm 18 and the sweeping brush 136 to rotate, and the metal chips accumulated on the surface of the conical filter plate 131 are swept into the storage trough 133. The protrusion is pushed downward by the driving block 19, and the pressing block 491 squeezes the metal chips and squeezes the metal chips into a cake shape by squeezing the metal chips. The device uses the driving action of the second motor 15 to synchronously drive the two collecting mechanisms to work, thereby achieving the purpose of automatically cleaning metal residues and reducing the volume of the collected metal chips, thereby facilitating the collection and cleaning of the metal by the staff. The compressed metal chip blocks can be quickly taken out of the compressed metal blocks through the sealing plug 46, and the cleaning process is fast and convenient.

[0044] The lifting column 492 can slide along the cavity of the sleeve 493, so as to avoid damage caused by rigid collision between the lifting column 492 and the metal block in the sleeve 493 after the metal chips in the collection cavity 42 are full, thereby improving the service life of the collection mechanism.

[0045] like Fig.10 A fourth embodiment is shown, which mainly differs from the third embodiment in that the upper filter assembly 13 includes a conical filter plate 131 and a material storage plate 132 fixedly mounted on the outer wall of the conical filter plate 131, and a material storage trough 133 opened on the top of the material storage plate 132, a second discharge port 134 connected to the interior of the material storage trough 133 is opened on the side wall of the material storage plate 132, a sleeve 135 is provided on the top of the conical filter plate 131, and sweeping brushes 136 are fixedly connected on both sides of the outer wall of the sleeve 135, and a scraper 137 is fixedly connected to the end of the sweeping brush 136 away from the sleeve 135, the sleeve 135 is fixedly mounted on the outer wall of the transmission shaft 16, and the scraper 137 is slidably connected to the inside of the second discharge port 134.

[0046] The embodiment of the present invention further provides a method for conveying and separating a centralized cutting fluid conveying and separating system separated from a machine tool, and the specific method comprises the following steps:

[0047] Step 1, conveying cutting fluid: first, convey the cutting fluid mixed with metal debris after use into the separation cylinder 1 through the conveying component 2. During the conveying process of the cutting fluid, the cutting fluid falls on the top of the upper filter component 13 away from the first collecting mechanism 4 and the second collecting mechanism 5. The waste cutting fluid enters the conveying pipe 21 through the feeding hopper 22. The first motor 23 drives the auger 24 to rotate to convey the waste cutting fluid and metal cutting waste into the separation cylinder 1 together.

[0048] Step 2, multiple filtration: The mixture of cutting fluid and metal chips first falls to the top of the upper filter component 13 under the action of gravity, and the larger volume of metal chips is filtered first. The smaller volume of metal chips and cutting fluid fall to the top of the lower filter component 14 through the filter holes on the surface of the upper filter component 13. The filter holes on the surface of the lower filter component 14 are smaller than the inner diameter of the filter holes on the surface of the upper filter component 13. The cutting fluid enters the bottom of the separation cylinder 1 cavity through the filter holes on the surface of the lower filter component 14, and the small volume of metal chips remains on the surface of the lower filter component 14.

[0049] Step 3: Collecting metal scraps: After the filtering operation is completed, the second motor 15 is started to drive the transmission shaft 16 to rotate, and the metal scraps enter the first collecting mechanism 4 through the lower collecting port 6 and the upper collecting port 7. The metal scraps are compressed into a round cake shape. When the second motor 15 rotates, the driving arm 18 and the sweeping brush 136 are synchronously driven to rotate, and the metal scraps accumulated on the surface of the conical filter plate 131 are swept into the storage trough 133. 137 pushes the metal scraps accumulated in the storage trough 133 to move and enter the lower collecting port 6 and the upper collecting port 7 through the second discharge port 134, and then enter the upper feed port 44 and the lower feed port 45. The protrusion 498 is pushed downward by the driving block 19. As the metal scraps in the collection chamber 42 increase, And it reaches the bottom of the pressing block 491, the pressing block 491 squeezes the metal chips and uses the squeezing between the metal chips to squeeze the metal chips into a cake shape, and the sealing plug 46 is unscrewed every thirty minutes to clean the metal chip blocks inside the collection box 41. The lifting column 492 can slide along the cavity of the sleeve 493, which can avoid the rigid collision and damage of the lifting column 492 and the sleeve 493 after the metal chips in the collection chamber 42 are full. The filtered cutting fluid is discharged through the discharge pipe 12, and the cutting fluid that falls on the top of the conical block 10 continuously impacts it, and the finer mixed inside it is gradually impacted and slides into the collection tank 11. Since a magnet block is arranged inside the collection tank 11, the fine slag is adsorbed by it, and the sealing cover plate 9 can be removed after the cutting fluid is discharged to clean the fine gold and iron slag.
