Description

Technical Field

[0001] This utility model relates to the technical field of grinding machine filtration, and in particular to a magnetic filtration device for grinding machines. Background Technology

[0002] When the grinding machine coolant (including cutting fluid, emulsion, etc.) flows through the magnetic filter, the strong magnetic components inside the device (such as magnetic rollers, magnetic rods or magnetic drums) generate a high-intensity magnetic field. Ferromagnetic impurities are adsorbed and fixed on the surface of the magnetic components under the action of the magnetic field, while the purified coolant continues to be recycled through the filter channel.

[0003] Current magnetic filter devices for grinding machines have the following shortcomings:

[0004] 1) Most existing magnetic filter devices for grinding machines cannot filter iron filings separately during use. They only use ordinary filtration methods, which may not filter out some fine iron filings, thus reducing the filtration efficiency of the device.

[0005] 2) Most existing magnetic filter devices for grinding machines simply allow coolant to flow through the filter screen during use, and cannot utilize shaking force for filtration, thus reducing the filtration efficiency of the device.

[0006] 3) Most existing magnetic filter devices for grinding machines require water guns to clean the inside when not in use, making it impossible to open the entire device for cleaning, which makes the cleaning process more complicated for operators. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a magnetic filter device for a grinding machine. The magnetic filter device for a grinding machine includes a first housing 1 and a second housing 10. The top and bottom of one side of the first housing 1 and the second housing 10 are symmetrically hinged with hinge shafts 12, and the first housing 1 and the second housing 10 are hinged together by the hinge shafts 12. The top and bottom of the first housing 1 and the second housing 10 away from the hinge shafts 12 are fixedly installed with fixing rings 13. The fixing rings 13 are inserted with pins 14. The top of the first housing 1 and the second housing 10 are connected to the middle position of the top of the first housing 1 and the second housing 10, which are close to each other. The bottom of the first housing 1 and the second housing 10 are connected to the middle position of the bottom of the first housing 1 and the second housing 10, which are close to each other. The top of the inner side of the first housing 1 and the second housing 10 is provided with a magnetic filter assembly 2. The middle position and the bottom of the inner side of the first housing 1 and the second housing 10 are symmetrically provided with debris filter assemblies 3.

[0030] The interior of the debris filter assembly 3 is equipped with a filter screen plate 34. The first housing 1 and the second housing 10 are symmetrically fixed at the middle position and bottom of the inner side away from each other. The top of the mounting plate 33 is fixedly installed with a telescopic rod 31. The top of the telescopic rod 31 is fixedly installed with a placement plate 30, and the placement plate 30 is in contact with the bottom of the filter screen plate 34. The outside of the telescopic rod 31 is fitted with a spring 32, and the two ends of the spring 32 are in contact with the placement plate 30 and the mounting plate 33 respectively.

[0031] Support legs are symmetrically fixedly installed on both sides of the bottom of the first housing 1 and the second housing 10, which are far apart from each other. The bottom of the support legs is provided with anti-slip pads. The support legs make the device more stable when placed, and the anti-slip pads prevent the device from sliding when placed.

[0032] A sealing groove 15 is provided on the side of the first housing 1 and the second housing 10 that are close to each other. A sealing ring 16 is provided inside the sealing groove 15. The sealing groove 15 and the sealing ring 16 cooperate with each other to seal the closed part of the first housing 1 and the second housing 10, preventing water leakage from the device.

[0033] During use, the device is first placed in the designated location. After placement, the coolant to be filtered for the grinding machine is poured into the first housing 1 and the second housing 10 through the inlet 11. Then, the magnetic filter assembly 2 filters the iron filings. After the iron filings are filtered, the coolant falls with gravity, impacting the filter screen 34 during the fall. During the impact, the two sets of filter screens 34 filter other impurities in the coolant. Then, the impact force drives the filter screens 34 to pressurize the placement plate 30. The placement plate 30 then drives the telescopic rod 31 and the spring. 32 is compressed, and after compression, the elastic restoring force of spring 32 drives the filter screen plate 34 to reset, so that the filter screen plate 34 can shake up and down. The shaking force accelerates the filtration efficiency of the device. When there is too much debris inside the device, pull the pin 14 to pull the pin 14 out from the inside of the fixing ring 13. After pulling it out, the fixing of the first housing 1 and the second housing 10 is released. After the fixing is released, rotate the second housing 10 to open the second housing 10. After opening, take out the collection tank 22 and the filter screen plate 34. After taking them out, clean the debris inside the device to prevent the device from becoming blocked.

[0034] Example 2

[0035] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a magnetic ring 20 is installed on the inner side of the magnetic filter assembly 2, a plurality of magnets 21 are evenly installed on the inner side of the magnetic ring 20, and a collection groove 22 is placed on the inner side of the magnetic ring 20.

[0036] The two sets of magnetic rings 20 are semi-arc-shaped, and when the two sets of magnetic rings 20 are closed, they form a circular ring structure. The magnets 21 set in the circular structure enhance the magnetic attraction.

[0037] Multiple sets of drainage holes are evenly provided at the bottom of the collection tank 22, and the drainage holes correspond to the debris filter component 3. The drainage holes allow the coolant to fall normally.

[0038] During use, when the coolant is poured in, it passes through the collection tank 22. When passing through the collection tank 22, the iron filings in the coolant are attracted to the inner wall of the collection tank 22 by the cooperation of the magnetic ring 20 and the magnet 21.

[0039] The remaining structure is the same as that in Example 1.

[0040] Based on embodiments 1-2, the working principle of this utility model is as follows: In use, the device is first placed in the designated location. After placement, the coolant to be filtered for the grinding machine is poured into the first housing 1 and the second housing 10 through the inlet 11. During pouring, the coolant passes through the collection tank 22. As it passes through the collection tank 22, the magnetic ring 20 and magnet 21 work together to attract iron filings from the coolant to the inner wall of the collection tank 22. After filtering the iron filings, the coolant falls under gravity, impacting the filter screen 34. During this impact, the two sets of filter screens 34 filter other impurities in the coolant. Then, the impact force drives the filter screens 34 to further filter... The placement plate 30 is pressurized, and then the placement plate 30 drives the telescopic rod 31 and the spring 32 to compress. After compression, the elastic restoring force of the spring 32 drives the filter screen plate 34 to reset, so that the filter screen plate 34 can swing up and down. The force of the swing accelerates the filtration efficiency of the device. When there is too much debris inside the device, pull the pin 14 to pull the pin 14 out from the inside of the fixing ring 13. After pulling it out, the fixation of the first housing 1 and the second housing 10 is released. After the fixation is released, the second housing 10 is rotated to open the second housing 10. After opening, the collection tank 22 and the filter screen plate 34 are taken out. After taking them out, the debris inside the device is cleaned to prevent the device from becoming blocked.
