Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, and in particular relates to a cutting fluid oil-water separation device. Background Art

[0002] Cutting fluid is an industrial liquid widely used in metal cutting and grinding processes. It is mainly used to cool and lubricate tools and workpieces, and has multiple functions such as cleaning and rust prevention. Cutting fluid is usually a mixture of multiple ingredients, including water, oil and various additives; however, as the use time increases, a large amount of wastewater and waste oil will be mixed into the cutting fluid. These impurities will seriously affect the performance and stability of the cutting fluid, and even cause damage to machine tools and workpieces. Therefore, it is necessary to separate the oil and water of the cutting fluid.

[0003] Although existing cutting fluid oil-water separators can separate oil, paint on the surface of the workpiece being machined can mix with the guide rail oil leaking from the machine tool into the cutting fluid during machining. During the degreasing process, paint, oil, and metal chips mix together when the oil and water are separated, forming sludge. The sludge adheres to the inner wall of the oil collecting chamber of the separator, and over time, it accumulates and becomes difficult to drain, causing the oil collecting chamber to become clogged and requiring manual removal. This is detrimental to the continued operation of the oil-water separation process and reduces separation efficiency. Therefore, an improved cutting fluid oil-water separator is proposed.

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] Example:

[0025] like Figure 1-5 As shown, this embodiment provides a cutting fluid oil-water separation device, including an oil-water separator 1 and a scraper assembly 2 mounted on the oil-water separator 1. The scraper assembly 2 has a turntable 3 driven by a motor to rotate and two guide plates 4 arranged parallel to the ends of the oil-water separator 1. A separation chamber 5 is defined between the two guide plates 4. Slide plates 7 are slidably connected to the inner walls of the guide plates 4. A rotating rod 8 is rotatably connected between the two slide plates 7. A connecting rod 6 is rotatably connected to the turntable 3. The end of the connecting rod 6 is rotatably connected to the rotating rod 8, and a support rod 9 is also integrally provided at the end of the connecting rod 6.

[0026] A top plate 12 is fixedly installed on the top of the slide 7. A slide rod 13 is slidably connected to the top plate 12 through an opening. The bottom end of the slide rod 13 is fixedly connected to the bottom plate 14. A spring 15 is also installed between the slide rod 13 and the bottom plate 14. A scraper 16 is fixedly installed on the lower end surface of the bottom plate 14.

[0027] In a specific application scenario, the turntable 3 is driven by the motor to rotate, driving the connecting rod 6 and the support rod 9 to form a linkage, driving the scraper 16 to scrape, and in the process of the scraper 16 scraping the sludge in the separation chamber 5, the entire sliding of the slide plate 7 is horizontally displaced, so that the scraper 16 forms an elliptical motion trajectory and fits the bottom wall of the separation chamber 5 for cyclic scraping, thereby bringing the sludge out of the separation chamber 5 and then discharging it into the waste oil barrel through the inclined slide for collection and treatment. The following is a further description of the cutting fluid oil-water separation device of the present invention in conjunction with this application scenario.

[0028] Further, refer to Figure 1-5 The inner wall of the guide plate 4 is grooved with a slide groove 11, and the bottom end of the slide plate 7 is protruded outward and adapted to the slide groove 11 to maintain a sliding connection.

[0029] In this embodiment, in order to keep the sliding of the slide plate 7 stable, the bottom end of the slide plate 7 is provided with an outward protrusion and adapted to the slide groove 11 to maintain a sliding connection, thereby limiting the sliding direction of the slide plate 7, so that the connecting rod 6 drives the slide plate 7 to move back and forth in a stable horizontal direction under the rotation drive of the turntable 3, keeping the horizontal displacement of the scraper 16 stable, and achieving stable scraping.

[0030] For more details, see Figure 1-5 The inner wall of the slide plate 7 is grooved with a limiting groove 10, and both sides of the bottom plate 14 are provided with protrusions adapted to the limiting groove 10 and maintain a sliding connection.

[0031] In this embodiment, in order to drive the bottom plate 14 and the scraper 16 to move vertically up and down during the elastic driving of the spring 15 and realize the scraping of the scraper 16, protrusions that are compatible with the limit grooves 10 are provided on both sides of the bottom plate 14 and maintain a sliding connection, thereby limiting the lifting direction of the bottom plate 14 and avoiding deviation of the bottom plate 14 during the lifting process, causing the scraper 16 to be too close or too far from the bottom wall of the separation chamber 5 and affecting the scraping effect.

[0032] More preferably, referring to Figure 1-5 The separation chamber 5 is connected to the oil-water separator 1 through a pipeline and transports the oil sludge separated by the oil-water separator 1. The side of the separation chamber 5 connected to the oil-water separator 1 through a pipeline is arc-shaped and the arc is adapted to the scraping angle of the scraper 16. Both sides of the scraper 16 are in contact with the inner wall of the guide plate 4.

[0033] In this embodiment, in order to improve the scraping effect of the scraper 16, the side of the separation chamber 5 that maintains the pipeline connection with the oil-water separator 1 is set to be arc-shaped and the curvature is adapted to the scraping angle of the scraper 16. The two sides of the scraper 16 are in contact with the inner wall of the guide plate 4, so that the scraper 16 is in contact with the bottom wall and side wall of the separation chamber 5 to maintain stable scraping.

[0034] More preferably, referring to Figure 1-5 The support rod 9 is arranged in an arc shape and its end part contacts the lower end surface of the bottom plate 14. The top of the scraper 16 is grooved with a movable groove 17 and a movable space is reserved for the end of the support rod 9 through the movable groove 17.

[0035] In this embodiment, in order to enable the support rod 9 to apply pressure to the bottom of the base plate 14 during the rotation of the connecting rod 6, and thereby drive the scraper 16 to lift, the support rod 9 is arranged in an arc shape. Since the end of the support rod 9 needs to contact the base plate 14, and the scraper 16 is also arranged at the bottom of the base plate 14, in order to avoid collision between the end of the support rod 9 and the scraper 16, thereby forming motion interference, a movable groove 17 is grooved in the scraper 16 to reserve movable space for the end of the support rod 9, thereby maintaining the independence of the support rod 9 and the scraper 16.

[0036] Furthermore, refer to Figure 1-5 A reserved groove 18 is provided on one side of the slide bar 13 facing the turntable 3 , and the reserved groove 18 reserves space for the rotation of the connecting rod 6 .

[0037] In this embodiment, since the connecting rod 6 will change its position during the rotation driven by the turntable 3, in order to avoid collision and motion interference between the connecting rod 6 and the sliding rod 13, a reserved groove 18 is opened on the sliding rod 13 to reserve space for the rotation of the connecting rod 6, thereby maintaining the independence of the connecting rod 6 and the sliding rod 13.

[0038] Furthermore, refer to Figure 1-5 A limit plate is also fixedly installed on the top of the slide rod 13, and the sliding distance of the slide plate 7 is less than the length of the guide plate 4.

[0039] In this embodiment, in order to prevent the slide rod 13 from detaching from the top plate 12 during the elastic release of the spring 15, a limit plate is set on the top of the slide rod 13. At the same time, in order to prevent the slide plate 7 from sliding excessively and separating from the guide plate 4, the sliding distance of the slide plate 7 is set to be smaller than the length of the guide plate 4.

[0040] More specifically, see Figure 1-5 The end of the separation chamber 5 away from the oil-water separator 1 is connected to an inclined slide and a waste oil barrel is placed at the bottom of the slide.

[0041] In this embodiment, after the sludge is separated from the oil-water separator 1 and scraped out by the scraper 16, an inclined slide is provided to guide it for smooth discharge and to avoid accumulation, so that the sludge falls into the waste oil barrel under the action of gravity for collection and treatment.

[0042] Working principle:

[0043] In the cutting fluid oil-water separator of the present invention, when the sludge enters the separation chamber 5, the turntable 3 is driven by the motor to rotate, and the turntable 3 is simultaneously connected to one end of the connecting rod 6 for rotation, thereby driving one end of the connecting rod 6 to rotate and change its position, and the other end of the connecting rod 6 is connected to the rotating rod 8 for rotation, thereby driving the rotating rod 8 and the slide 7 to move synchronously through the rotation of the connecting rod 6, and the bottom end of the slide 7 is provided with an outward protrusion and adapted to the slide groove 11 to maintain a sliding connection, thereby driving the slide 7 as a whole to move back and forth in the horizontal direction under the guidance of the slide groove 11;

[0044] At the same time, the support rod 9 integrally provided at the end of the connecting rod 6 will also be synchronously toggled back and forth with the rotation of the connecting rod 6, and the end of the support rod 9 will conflict with the lower end surface of the bottom plate 14. Therefore, the support rod 9 intermittently squeezes the lower end surface of the bottom plate 14 during the toggling process. When the support rod 9 squeezes the lower end surface of the bottom plate 14, the bottom plate 14 is lifted and forces the spring 15 to compress and accumulate force. When the support rod 9 is away from the bottom plate 14, the spring 15 releases its elasticity and drives the bottom plate 14 and the scraper 16 to press down, driving the scraper 16 to scrape the sludge in the separation chamber 5;

[0045] While the scraper 16 is scraping the sludge in the separation chamber 5, it will also move horizontally with the overall sliding of the slide plate 7, so that the scraper 16 forms an elliptical motion trajectory and fits the bottom wall of the separation chamber 5 for cyclic scraping, thereby bringing the sludge out of the separation chamber 5 and then discharging it into the waste oil barrel through the inclined slide for collection and treatment.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
