Description

Technical Field

[0001] This utility model relates to the field of oil separator technology, specifically to a machine tool cutting fluid oil separation device. Background Technology

[0002] In the field of machine tool processing, cutting fluid, as a key auxiliary medium for ensuring machining accuracy and extending tool life, directly affects the operating efficiency and machining quality of the machining system. During actual machining, cutting fluid is prone to contamination with impurities during recycling due to various factors, such as leakage of lubricating oils from machine tool guideways and hydraulic systems, residual oil from workpiece surface pretreatment, and waste oil generated during machining, leading to an increase in the impurity content in the cutting fluid system. To address these issues, existing technologies often employ oil-liquid separation devices to remove impurities from the cutting fluid. Gravity sedimentation separation is widely used due to its simple structure and low cost. However, gravity sedimentation separation has significant drawbacks in practical applications: low separation efficiency, requiring a long settling time to achieve effective stratification, severely impacting the recycling efficiency of the cutting fluid and potentially causing machining interruptions due to insufficient cutting fluid supply; furthermore, to ensure separation effectiveness, the sedimentation tank needs a large volume, occupying significant workshop space, hindering optimized production layout, and failing to meet the demands of modern machine tool processing for efficient and compact production equipment.

[0003] Therefore, this utility model provides a machine tool cutting fluid oil-liquid separation device. Summary of the Invention

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 A cutting fluid oil-liquid separation device for machine tool processing includes a cutting fluid separation tank 1 and an oil tank 11. A filter ring 2 is provided above the top opening of the cutting fluid separation tank 1. Several filter holes 21 are provided through the filter ring 2. Adsorbent 22 is installed in each of the filter holes 21. An oil guide flat tube 12 is installed above the oil tank 11. The oil guide flat tube 12 is located inside the filter ring 2. A docking hole 121 is opened at the top of the oil guide flat tube 12. The docking hole 121 corresponds to the position of the filter hole 21 above. A discharge pipe 4 is provided inside the filter ring 2. A first connecting pipe 41 and a second connecting pipe 42 are respectively installed at both ends of the discharge pipe 4. The second connecting pipe 42 is connected to the cutting fluid separation tank 1 on one side through a vacuum pump 43. The discharge pipe 4 is located below the oil guide flat tube 12.

[0017] It should be noted that, in this embodiment, a one-way valve is provided at the connection between the discharge pipe 4 and the first connecting pipe 41 and the second connecting pipe 42, so that the first connecting pipe 41 and the second connecting pipe 42 can work separately.

[0018] Specifically, the oil and cutting fluid in the machine tool can be directly guided to the discharge pipe 4 through the first connecting pipe 41. At the same time, the vacuum pump 43 operates, and the oil that has settled at the top of the cutting fluid separator 1 is also pumped through the second connecting pipe 42 and transported to the discharge pipe 4. The discharge pipe 4 drips the oil and cutting fluid onto the filter ring 2 through the discharge hole at the bottom. Several filter holes 21 through the filter ring 2 are each filled with adsorbent 22. The cutting fluid can pass through the adsorbent 22 and fall into the cutting fluid separator 1, while the oil will be blocked by the adsorbent 22. When the filter ring 2 rotates, it causes the adsorbent 22 to rotate to the top, and the blocked oil falls into the oil guide flat pipe 12. The docking hole 121 at the top corresponds to the filter hole 21 above, which can accurately receive the oil and guide it out. In addition, one-way valves are provided at the connection points of the discharge pipe 4 with the first connecting pipe 41 and the second connecting pipe 42, so that the two can work independently and avoid mutual interference. The cutting fluid and the small amount of residual oil enter the cutting fluid separator 1. Since the cutting fluid separator 1 is L-shaped and has a pipe connected to the machine tool on one side, which is located at the lower part of the cutting fluid separator 1, the purified cutting fluid can be returned to the machine tool for recycling, while the oil continues to settle above the cutting fluid separator 1, which is convenient for the second connecting pipe 42 to further extract and separate it.

[0019] In one embodiment of this utility model, such as Figures 1-4 As shown, annular baffles 23 are installed on both sides of the filter ring 2. The outer diameter of the annular baffles 23 is larger than that of the filter ring 2, and the inner diameter of the annular baffles 23 is smaller than that of the filter ring 2.

[0020] Specifically, when the discharge pipe 4 drips oil and cutting fluid onto the filter ring 2, the annular baffle 23 can prevent the oil and cutting fluid from splashing or leaking from both sides of the filter ring 2, ensuring that they are concentrated in the filter hole 21 area of ​​the filter ring 2 and fully contact the adsorbent 22, improving the efficiency of the oil being blocked by the adsorbent 22, while ensuring that the cutting fluid can accurately pass through the adsorbent 22 and enter the cutting fluid separation box 1.

[0021] In one embodiment of this utility model, such as Figures 1-4 As shown, the top of the cutting fluid separator 1 is provided with two support rings 3, and two uprights 31 are provided below each of the two support rings 3. All four uprights 31 are installed on the top of the cutting fluid separator 1. Toothed rings 24 are installed on the opposite sides of the two annular baffles 23. The toothed rings 24 are rotatably connected to the outside of the corresponding support rings 3.

[0022] Specifically, the two support rings 3 at the top of the cutting fluid separator 1 are fixedly installed by four uprights 31 to provide stable support for the filter ring 2; the annular baffles 23 on both sides of the filter ring 2 are equipped with toothed rings 24 on the opposite side. The toothed rings 24 are rotatably connected to the outside of the corresponding support rings 3 to form a reliable rotational support structure. During operation, the toothed rings 24 can rotate stably along the outside of the support rings 3, driving the filter ring 2 and the annular baffles 23 to rotate synchronously, ensuring that the adsorbent 22 in the filter hole 21 can continuously circulate to the bottom of the discharge pipe 4 to receive oil and cutting fluid, and when rotating to the top, the adsorbed oil falls precisely into the docking hole 121 of the oil guide flat pipe 12.

[0023] In one embodiment of this utility model, such as Figures 1-4 As shown, a vertical plate 32 is installed at the top of the support ring 3. A gear 33 is rotatably connected to one side of the vertical plate 32. The gear 33 meshes with the corresponding gear ring 24 below. A drive motor 331 that is connected to the gear 33 is installed on the other side of the vertical plate 32.

[0024] Specifically, during operation, after the drive motor 331 starts, it drives the gear 33 to rotate. Since the gear 33 meshes with the gear ring 24, the rotation of the gear 33 will drive the gear ring 24 to rotate along the outside of the support ring 3, thereby driving the annular baffle 23 connected to the gear ring 24 and the filter ring 2 to rotate synchronously. This allows the filter holes 21 on the filter ring 2 and the internal adsorbent 22 to continuously circulate through the liquid drop area below the discharge pipe 4 and above the docking hole 121 of the oil guide flat pipe 12, realizing the automated and continuous operation of oil-liquid separation.

[0025] In one embodiment of this utility model, such as Figures 1-4 As shown, a partition plate 34 is installed between the two support rings 3. Two arc-shaped baffles 35 are installed at the top of the partition plate 34. The two arc-shaped baffles 35 and the partition plate 34 are slidably connected to the inner wall of the filter ring 2. When the filter hole 21 reaches the space between the two arc-shaped baffles 35, oil is discharged.

[0026] Specifically, when the filter hole 21 moves below the discharge pipe 4, it is in the area not blocked by the arc-shaped baffle 35 and the partition plate 34. The oil and cutting fluid dripping from the discharge pipe 4 can smoothly enter the filter hole 21. The cutting fluid passes through the adsorbent 22 and falls into the cutting fluid separation tank 1, while the oil is blocked and retained by the adsorbent 22. As the filter ring 2 continues to rotate, the filter hole 21 carrying the oil gradually moves to the area between the two arc-shaped baffles 35. At this time, the arc-shaped baffles 35 and the partition plate 34 block the bottom of the filter hole 21, preventing the oil from dripping before reaching the designated position. When the filter hole 21 reaches the area above the two arc-shaped baffles 35, the oil that has lost its bottom blockage falls precisely into the docking hole 121 of the oil guide flat pipe 12 under the action of gravity, completing the directional discharge of the oil.

[0027] In one embodiment of this utility model, such as Figures 1-4As shown, an air pump 5 is provided at the top of the filter ring 2, and an exhaust hood 51 is installed at the bottom of the air pump 5. The exhaust hood 51 is slidably connected between the top of the filter ring 2 and the two annular baffles 23, and the gap between the exhaust hood 51 and the two arc baffles 35 corresponds to the position of the gap.

[0028] Specifically, when the filter ring 2 rotates the filter hole 21 containing oil to the area between the two arc-shaped baffles 35, the air pump 5 starts and blows airflow through the exhaust hood 51 to the filter hole 21 and the internal adsorbent 22 in this area; the airflow can act on the oil remaining on the surface of the adsorbent 22, on the one hand accelerating the oil to detach from the adsorbent 22 and avoiding oil residue from affecting the subsequent adsorption effect, and on the other hand assisting the oil to fall quickly and accurately into the docking hole 121 of the lower oil guide flat tube 12 under the action of gravity.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: When the device is working, the oil and cutting fluid in the machine tool are directly introduced into the discharge pipe 4 through the first connecting pipe 41. At the same time, the vacuum pump 43 draws the oil that has settled in the upper part of the cutting fluid separator 1 through the second connecting pipe 42 and sends it into the discharge pipe 4. The discharge pipe 4 drips the oil and cutting fluid onto the filter ring 2 through the lower discharge hole. The one-way valve at the connection between the discharge pipe 4 and the two connecting pipes ensures that the two work independently. The adsorbent 22 in the filter hole 21 of the filter ring 2 allows the cutting fluid to pass through and fall into the cutting fluid separator 1, blocking the oil. The drive motor 331 drives the gear 33 on the vertical plate 32 to rotate. The gear 33 meshes with the drive ring. The toothed ring 24 on the baffle 23 rotates along the support ring 3. The support ring 3 is fixed by the upright 31, which in turn drives the filter ring 2 to rotate. During the rotation of the filter ring 2, the filter hole 21 carrying the oil moves between the two arc-shaped baffles 35. The arc-shaped baffles 35 and the partition plate 34 are slidably connected to the inner wall of the filter ring 2. The arc-shaped baffles 35 and the partition plate 34 block the area below the filter hole 21. The air pump 5 blows air into this area through the exhaust hood 51 to accelerate the oil from the adsorbent 22. The oil finally falls into the docking hole 121 of the oil guide flat pipe 12 and is discharged. The pipe at the bottom of the cutting fluid separator 1 will return the purified cutting fluid to the machine tool, and the oil in the upper part will be extracted a second time.
