Description

Technical Field

[0001] This application relates to the field of filtration and separation equipment technology, and more specifically, to a filtration mechanism for separating grinding fluid in a grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to perform precision machining on the surface of a workpiece. It is mainly used to improve the dimensional accuracy, shape accuracy and surface finish of the workpiece. Grinding fluid (also known as grinding coolant or cutting fluid) is a key auxiliary medium used for cooling, lubrication, cleaning and rust prevention in grinding. It can directly affect the machining quality, grinding wheel life and the accuracy of the workpiece surface.

[0003] In related technologies, in order to solve the problem that iron filings in grinding fluid are in a free state or are deposited at the bottom of the grinding fluid and are inconvenient to retrieve, for example, the prior art patent with publication number CN220479077U provides a grinding fluid iron filings filtration and separation device. This device improves the adsorption and separation efficiency of iron filings by diverting, filtering and adsorbing iron filings impurities in the grinding fluid, and further improves the filtration effect of iron filings impurities in the grinding fluid.

[0004] Although the existing technical solutions mentioned above have solved the problem of the difficulty in retrieving iron filings from the grinding fluid by using multiple separation cylinders, the gaps between the multiple separation cylinders are small. Even if the water stains on the separation cylinders are completely removed by heating rods, the iron filings and impurities are difficult to detach smoothly from the guide rail due to the lack of a power source, which can easily cause blockage between the multiple separation cylinders.

[0005] In view of this, we propose a filtration mechanism for separating grinding fluid in grinding machines. Utility Model Content

[0006] The purpose of this application is to provide a filtration mechanism for separating grinding fluid in grinding machines, which can effectively solve the problem in the prior art where the gap between the original separation cylinders is small and iron filings are difficult to remove, and achieve the effect of smooth discharge of iron filings after separation of grinding fluid without clogging.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-6 This application discloses a filtration mechanism for separating grinding fluid in a grinding machine, comprising a storage tank 1, a material blocking mechanism 2, a rotating shaft 3, and a material unloading mechanism 4. The storage tank 1 has an inlet 11 fixedly connected to its top, and a partition plate 12 fixedly connected to its inner wall. The material blocking mechanism 2 is disposed inside the inlet 11 for coarse filtration of the grinding fluid. The rotating shaft 3 is rotatably connected to the middle of the storage tank 1 and is driven by an external force to rotate within the storage tank 1. Several stirring frames 31 are fixedly connected to the outer wall of the rotating shaft 3. The material unloading mechanism 4 is disposed at the end of the stirring frames 31. The material unloading mechanism 4 includes a magnetic rod 41 slidably connected to the inner wall of the stirring frame 31. The partition groove located inside the partition plate 12 is used to adsorb iron filings in the cutting fluid. The magnetic rod 41 slides in the stirring rack 31 under external force. The inner walls of the partition plate 12 are all inclined to form the bottom inclined partition groove. The bottom of the liquid storage tank 1 is provided with a liquid outlet pipe 13 and a chip discharge port 14. The liquid outlet pipe 13 and the liquid storage tank 1 are fixedly connected by a flange 15. A filter screen A16 is fixedly connected to the top of the liquid outlet pipe 13. Multiple support seats 17 are fixedly connected to the bottom of the liquid storage tank 1. The inner bottom wall of the liquid storage tank 1 is a sloping structure. A speed-regulating motor is fixedly installed at the bottom of the liquid storage tank 1. The bottom of the rotating shaft 3 is fixedly connected to the output end of the speed-regulating motor.

[0031] The storage tank 1 needs to be installed in the designated work area, and the end of the outlet pipe 13 needs to be connected to an external pipeline. Simultaneously, the filter screen A16 needs to be sealed. Grinding fluid can then be added to the storage tank 1 through the inlet 11. When the grinding fluid passes through the filter screen B21, the filter screen B21 can intercept large iron filings particles contained in the grinding fluid. At the same time, an appropriate amount of flocculant can be added to the storage tank 1 through the inlet 11 (the function of adding an appropriate flocculant is to adsorb particles and "bridge" between particles, thereby promoting aggregation), to agglomerate small iron filings particles in the grinding fluid. Once the grinding fluid has been added to the storage tank 1, the operator can start the speed-regulating motor at the bottom of the rotating shaft 3. This allows the rotating shaft 3 to rotate at high speed, driving the stirring frame 31 to move synchronously and unfolding the magnetic rod 41. This helps to blend the grinding fluid and flocculant in the storage tank 1. Then, the rotating shaft 3 is switched to a low-speed mode. During this process, small iron filings are aggregated into larger particles. Simultaneously, the unfolded magnetic rod 41 rotates within the groove of the partition plate 12, and the magnetic force it generates helps to collect iron filings and impurities in the grinding fluid. On its surface, and some of the large particles after aggregation, can also fall to the bottom wall of the storage tank 1 for subsequent discharge. After the grinding fluid is separated, the valve at the end of the outlet pipe 13 can be opened to discharge the treated grinding fluid. Subsequently, under the action of the unloading mechanism 4, the magnetic rod 41 can slide into the stirring frame 31 and intercept the iron filings on the outer wall of the stirring frame 31, which are then discharged with the unfolded filter screen A16. At the same time, the inclined surface of the inner wall of the partition plate 12 can reduce the adhesion of water stains and impurity particles. This step is carried out by the rotating shaft 3 and the stirring... The rotation of the mixing rack 31 accelerates the fusion of grinding fluid and flocculant, forming large iron filings for subsequent separation. The partition plate 12 increases the adsorption distance between the iron filings and the magnetic rod 41, solving the problem of small gaps between the original separation cylinders and difficulty in removing iron filings. This achieves the effect of smooth discharge of iron filings after grinding fluid separation without clogging. The filter screen A16 at the top of the outlet pipe 13 further intercepts impurities in the grinding fluid. The flange 15 can also be removed later to replace and maintain the outlet pipe 13.

[0032] Reference Figure 2 , Figure 3 and Figure 4Based on the above embodiments, in order to drive the magnetic rod 41 to retract into the stirring frame 31 to complete the cleaning effect of iron filings on the surface of the magnetic rod 41, the unloading mechanism 4 specifically includes a rubber plate 42 fixed to the end of the magnetic rod 41, a limiting slider 43 fixed to the other end of the magnetic rod 41, the limiting slider 43 being slidably connected to the inner wall of the stirring frame 31, a steel wire rope 44 being fixedly connected to the outside of the limiting slider 43, an inner tube 45 being fixedly connected to the end of several steel wire ropes 44, the inner tube 45 being axially slidably connected to the inner wall of the rotating shaft 3, the top of the inner tube 45 being through the rotating shaft 3, and the top of the liquid inlet 11 being connected to the liquid outlet of the grinding machine.

[0033] The inner tube 45 can be pulled upwards, allowing it to slide up and down along the inner wall of the rotating shaft 3. Simultaneously, several steel wire ropes 44 can be pulled upwards, causing the magnetic rod 41 to be pulled into the mixing rack 31. Iron filings adhering to the surface of the magnetic rod 41 are pushed to the position of the rubber plate 42 until the magnetic rod 41 is completely retracted, removing and dropping the surface impurities. When the magnetic rod 41 needs to be unfolded, the rotating shaft 3 is started, and the unfolding is achieved under the action of centrifugal force. This step, combined with the upward movement of the inner tube 45, can remove the iron filings adhering to the outer wall of the magnetic rod 41, facilitating subsequent material feeding. Furthermore, the action of the rubber plate 42 can reduce the problem of some iron filings adhering to the outer wall of the magnetic rod 41.

[0034] Reference Figure 2 and Figure 5 The material blocking mechanism 2 includes a filter screen B21 disposed inside the liquid inlet 11. A mounting frame 22 is fixedly disposed on the top of the filter screen B21. Several support frames 23 are fixedly connected to the top of the mounting frame 22. A connector 24 is slidably connected to the outer wall of the support frame 23. The connector 24 is fixedly connected to the liquid inlet 11. The filter screen B21 has a semi-circular structure with a concave bottom.

[0035] When the grinding fluid is transferred to the filter screen B21, the large iron filings separated from the filter screen B21 are concentrated at the bottom of the filter screen due to its arc shape. When the filter screen B21 needs to be removed for cleaning, the operator can simply hold one end of the support frame 23 and pull it upwards. This step, thanks to the sliding support frame 23, facilitates the maintenance or replacement of the filter screen B21. Furthermore, the arc shape of the filter screen B21 allows for the concentrated placement of separated particles, preventing the top of the filter screen B21 from being completely blocked and affecting normal filtration.

[0036] Reference Figure 2 , Figure 4 and Figure 6The storage tank 1 is equipped with a scraping mechanism 5. The scraping mechanism 5 includes an electromagnetic plate 51 rotatably connected to the bottom wall of the storage tank 1. An anti-wear strip is provided between the electromagnetic plate 51 and the bottom wall of the storage tank 1. The electromagnetic plate 51 is detachably mounted on the outside of the rotating shaft 3. An energized slip ring 55 is fixedly connected to the top inner wall of the storage tank 1. The inner ring of the energized slip ring 55 is axially slidably connected to the inner tube 45. The electromagnetic plate 51 is electrically connected to the inner ring of the energized slip ring 55. The outer ring of the energized slip ring 55 is electrically connected to an external power source. The inner ring of the energized slip ring 55 is rotatably mounted on the inside of the outer ring. Two mounting brackets 52 are fixedly connected to the top of the electromagnetic plate 51. A support plate 53 is fixedly connected to the end of the mounting bracket 52. The support plate 53 and the rotating shaft 3 are fixedly connected by bolts 54.

[0037] First, turn on the external power supply so that the energized slip ring 55 is powered on. Then, the circuit running inside the inner tube 45 can be used to energize the electromagnetic plate 51, causing the electromagnetic plate 51 to generate an attractive force (generated by the energization of the internal coil to attract metal parts; the magnetic force disappears when the power is turned off; this type of product is widely used in the field of machine tool accessories, has stable and reliable characteristics, and is commonly found in the metal processing and automotive manufacturing industries). It can also attract settled metal particles. When it is necessary to remove the electromagnetic plate 51 and the impurities on the bottom wall of the storage tank 1, the power supply to the external energized slip ring 55 can be turned off first. At the same time, when the electromagnetic plate 51 rotates, it can attract the metal particles. Some residual impurities will be scraped off and transferred to the filter screen A16 for subsequent removal. When it is necessary to replace the electromagnetic plate 51, the cover plate on top of the liquid storage tank 1 can be opened first, and the two bolts 54 can be removed one by one with the help of tools. This step, together with the rotating electromagnetic plate 51, can adsorb the metal impurities at the bottom of the liquid storage tank 1, reducing the clogging of the filter screen A16. At the same time, after the electromagnetic plate 51 is de-energized, the continued rotation of the electromagnetic plate 51 can clean the bottom wall area of ​​the liquid storage tank 1 and the filter screen A16, and also reduce the adhesion of impurities on the filter screen A16, so as to facilitate the subsequent discharge of grinding fluid.

[0038] In summary, the filtration mechanism for separating grinding fluid in a grinding machine disclosed in this application requires the storage tank 1 to be installed in a designated working area, and the end of the outlet pipe 13 to be connected to an external pipeline. Simultaneously, the filter screen A16 is sealed. Grinding fluid can then be added to the storage tank 1 through the inlet 11. When the grinding fluid passes through the filter screen B21, the filter screen B21 intercepts large iron filings particles contained in the grinding fluid. Simultaneously, an appropriate amount of flocculant (which adsorbs microparticles and "bridges" between them, promoting aggregation) can be added to the storage tank 1 through the inlet 11 to aggregate small iron filings in the grinding fluid. After the grinding fluid has been added to the storage tank 1, the operator can then... Start the speed-regulating motor at the bottom of the rotating shaft 3, allowing it to rotate at high speed initially. This drives the stirring frame 31 to move synchronously, unfolding the magnetic rod 41 and fusing the grinding fluid and flocculant in the storage tank 1. Then, switch the rotating shaft 3 to low speed. During this process, small iron filings are aggregated into larger particles. Simultaneously, the unfolded magnetic rod 41 rotates within the groove of the partition plate 12, and the resulting magnetic force collects iron filings and impurities from the grinding fluid on its surface. Some of the aggregated larger particles also fall to the bottom wall of the storage tank 1 for later discharge. After the grinding fluid separation is complete, open the valve at the end of the outlet pipe 13 to discharge the treated grinding fluid. Further processing is then carried out... Under the action of the unloading mechanism 4, the magnetic rod 41 slides into the mixing rack 31, intercepting and dropping iron filings on the outer wall of the mixing rack 31. These are then discharged with the unfolded filter screen A16. Simultaneously, the inclined surface of the inner wall of the partition plate 12 reduces the adhesion of water stains and impurities. The inner tube 45 can be pulled upwards, allowing it to slide up and down along the inner wall of the rotating shaft 3. At the same time, several steel wire ropes 44 are moved upwards, pulling the magnetic rod 41 into the mixing rack 31. Iron filings adhering to the surface of the magnetic rod 41 are pushed to the position of the rubber plate 42 until the magnetic rod 41 completely retracts, removing and dropping surface impurities. The magnetic rod 41 then needs to be completely retracted. When the force bar 41 unfolds, the rotating shaft 3 is started, and the unfolding is achieved under the action of centrifugal force. When the grinding fluid is transferred to the filter screen B21, the large pieces of iron filings separated from the filter screen B21 can be concentrated at the bottom of the filter screen B21 due to its arc-shaped feature. When the filter screen B21 needs to be removed for cleaning, the operator can hold one end of the support frame 23 and pull it upwards. The external power supply can be turned on first, so that the energized slip ring 55 can be energized, which can then be combined with the wiring inside the inner tube 45 to energize the electromagnetic plate 51, so that the electromagnetic plate 51 generates an attractive force and can attract the metal particles that have settled to the bottom. When the electromagnetic plate 51 and the impurities on the bottom wall of the liquid storage tank 1 need to be removed later, the power supply to the external energized slip ring 55 can be turned off first.Simultaneously, as the electromagnetic plate 51 rotates, it scrapes away some residual impurities and transfers them to the filter screen A16 for subsequent removal. When the electromagnetic plate 51 needs to be replaced, the cover plate on top of the liquid storage tank 1 can be opened first, and then the two bolts 54 can be removed one by one using a tool.
