Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding fluid treatment technology, and in particular to a grinding fluid separation and recovery device. Background Technology
[0002] During the machining process of metals, grinding fluid is needed for cooling and lubrication. A large amount of metal shavings are generated during processes such as grinding and polishing. The waste fluid contains both ferromagnetic and non-ferromagnetic impurities, which means that the grinding fluid cannot be recycled without treatment. It is necessary to use separation equipment to separate the substances in the grinding fluid and then carry out centralized recycling treatment.
[0003] Existing separation methods include filtration, sedimentation, and magnetic separation. Filtration uses multiple filters to filter the grinding fluid, but this method cannot separate ferromagnetic metal chips from non-ferromagnetic impurities, resulting in waste of metal chips and requiring frequent filter replacements to prevent clogging, leading to poor separation efficiency. Sedimentation utilizes mass difference, collecting the grinding fluid and allowing it to settle naturally for separation of heavier metals and impurities. However, this method is time-consuming and has poor separation efficiency, making it difficult to completely remove fine impurities. Magnetic separation has the drawback of poor removal of non-ferromagnetic impurities. Therefore, further improvements are needed. Utility Model Content

[0013] (1) This grinding fluid separation and recovery device filters the grinding fluid by setting a vibrating screen plate. The concave-convex screen plate is installed at an angle and can vibrate left and right to shake the fixed particles into the groove. During the downward movement, the solid particles inside the groove will shake left and right with the vibration and collide with the side wall of the groove. The water contained in the particles can be fully removed and the particles that are stuck together can be shaken apart for further separation. When vibrating, the drive motor rotates, which drives the cam to rotate, and then pushes the second support block to move inward.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Please see Figures 1-4 This utility model provides an embodiment of a grinding fluid separation and recovery device, characterized in that: it includes a support frame 1, the support frame 1 includes a base 11 and side support plates 12, the side support plates 12 are fixed on both sides of the upper end of the base 11, a liquid collection tank 2 is provided at the upper end of the base 11, a vibrating screen plate 3 is provided on the upper side of the liquid collection tank 2, the vibrating screen plate 3 is installed between the side support plates 12, a magnetic toothed rotating cylinder 4 is provided on the vibrating screen plate 3, a motor is installed on the side of the magnetic toothed rotating cylinder 4, a scraper plate 5 is provided at the lower rear end of the magnetic toothed rotating cylinder 4, the scraper plate 5 is in contact with the surface of the magnetic toothed rotating cylinder 4, a metal recovery mechanism 6 is fixed at the end of the scraper plate 5, a grinding fluid inlet 8 is fixed at the upper right end of the side support plate 12 and is located above the vibrating screen plate 3, a waste recovery tank 7 is provided at the front end of the liquid collection tank 2 and is located below the end outlet of the vibrating screen plate 3, and a liquid outlet pipe 9 is provided at the rear end of the liquid collection tank 2;
[0023] Based on the above structural features, when this utility model is in operation, the grinding fluid flows into the vibrating screen plate 3 from the grinding fluid inlet 8. After being strongly vibrated by the vibrating screen plate 3, the fixed particles in the grinding fluid can be filtered out, allowing the liquid to seep into the collection tank 2. After the fixed particles are shaken apart on the vibrating screen plate 3, the magnetic metal debris is attracted by the magnetic toothed rotating cylinder 4, and the debris adsorbed on the surface of the magnetic toothed rotating cylinder 4 is scraped off by the scraper plate 5. Then, it is recycled by the metal recycling mechanism 6. The remaining non-magnetic debris will fall into the waste recycling tank 7 with gravity, realizing the separation of magnetic and non-magnetic impurities. After solid separation, the grinding fluid in the collection tank 2 can flow out through the liquid outlet pipe 9 for recycling.
[0024] Please see Figures 1-4 The liquid collection tank 2 includes a sedimentation tank 21. A liquid outlet 22 is provided on the right side wall of the sedimentation tank 21. A finished product tank 23 is provided on the right side of the sedimentation tank 21. The grinding fluid can flow into the finished product tank 23 after the liquid level exceeds the liquid outlet 22. The liquid outlet pipe 9 is connected to the finished product tank 23.
[0025] In accordance with the above structural features, when this utility model is in operation, the filtered grinding fluid first flows into the sedimentation tank 21. When the liquid level exceeds the outlet 22, the excess liquid flows into the finished product tank 23. The outlet pipe 9 is connected to the finished product tank 23. If there are still some fine particles in the grinding fluid in the sedimentation tank 21, they will sink to the bottom of the tank due to gravity, thus enhancing the separation effect.
[0026] Please see Figures 1-4The vibrating screen plate 3 includes a concave-convex screen plate 31, which is installed at an angle. The concave-convex screen plate 31 is provided with multiple concave grooves, which are low in the middle and high on both sides. The surface of the concave-convex screen plate 31 is provided with fine screen holes. Support block 1 32 and support block 2 33 are fixed on the left and right sides of the concave-convex screen plate 31. Support block 1 32 and support block 2 33 are slidably connected to the side support plate 12. A spring 36 is provided at the right end of support block 1 32. A cam 34 is provided on the left side of support block 2 33 and is in contact with the cam 34. A drive motor 35 is provided at the end of the cam 34. A protective shell is provided on the outside of the spring 36 and the cam 34.
[0027] Please see Figures 1-4 The metal recycling mechanism 6 includes an L-shaped collecting plate 61, which is fixed to the end of the scraper plate 5. An electric slide table 62 is fixed on the rear wall of the L-shaped collecting plate 61. An electric slider 63 is installed on the electric slide table 62. A scraper 64 is fixed on the electric slider 63. A collection basket 65 is fixed on the outside of the side support plate 12. The collection basket 65 is located on the left and right sides of the L-shaped collecting plate 61.
[0028] In accordance with the above structural features, when this utility model is in operation, the concave-convex sieve plate 31 is installed at an angle and can vibrate left and right, shaking the fixed particles into the groove. During the downward movement, the solid particles inside the groove will sway left and right with the vibration and collide with the side wall of the groove, which can fully remove the moisture contained in the particles and shake apart the particles that are stuck together, facilitating further separation. During vibration, the drive motor 35 rotates, driving the cam 34 to rotate, which in turn pushes the second support block 33 to move inward. At this time, the first support block 32 contacts the spring 36, and the spring 3... 6 is compressed, and when the cam 34 rotates 180 degrees, the spring 36 returns to its original state, pushing the support block 32 to move outward. This process is repeated to create a vibration effect. By setting a magnetic toothed rotating cylinder 4 on the vibrating screen plate 3, the magnetic metal debris in the initially shaken solid particles is adsorbed. The debris adsorbed on the surface of the magnetic toothed rotating cylinder 4 is scraped off by the scraper plate 5 and falls into the L-shaped collection plate 61. Finally, the electric slide table 62 drives the scraper 64 to scrape it into the collection basket 65. The remaining non-magnetic debris will fall into the waste recycling tank 7 with gravity.
[0029] Working Principle: In use, the grinding fluid flows into the vibrating screen plate 3 through the grinding fluid inlet 8. The concave-convex screen plate 31 is installed at an angle and can vibrate left and right, shaking the fixed particles into the groove. During the downward movement, the solid particles inside the groove will sway left and right with the vibration and collide with the side wall of the groove, which can fully remove the moisture contained in the particles and shake apart the particles that are stuck together, making it easier to separate them further. During vibration, the drive motor 35 rotates, which drives the cam 34 to rotate, thereby pushing the second support block 33 to move inward. At this time, the first support block 32 contacts the spring 36, and the spring 36 is compressed. When the cam 34 rotates 180 degrees, the spring 36 returns to its original state, pushing the support block 32 to move outward. This process repeats, creating a vibration effect. After the fixed particles are shaken apart on the vibrating screen plate 3, the magnetic metal debris is attracted by the magnetic toothed rotating drum 4. The debris adsorbed on the surface of the magnetic toothed rotating drum 4 is scraped off by the scraper plate 5 and then recycled by the metal recycling mechanism 6. The remaining non-magnetic debris falls into the waste recycling tank 7 by gravity, thus separating magnetic and non-magnetic impurities. The grinding fluid in the liquid collection tank 2, after solid separation, can flow out through the liquid outlet pipe 9 for reuse.
