Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting fluid filtration, in particular to a cutting fluid filtration device. Background Art
[0002] Cutting fluid (referred to as cutting fluid) has a lubricating effect during the cutting process, which can reduce the friction between the rake face and the chips, and the flank face and the processed surface, forming a partial lubricating film, thereby reducing cutting force, friction and power consumption, reducing the surface temperature and tool wear at the friction point between the tool and the workpiece blank, and improving the cutting performance of the workpiece material; cutting fluid also has a cooling effect, through the convection and vaporization between the cutting fluid and the tool (or grinding wheel) heated by cutting, the chips and the workpiece, the cutting heat is taken away from the tool and the workpiece, thereby effectively reducing the cutting temperature, reducing the thermal deformation of the workpiece and tool, maintaining the tool hardness, and improving the processing accuracy and tool durability.
[0003] During the machine tool processing process, if the cutting fluid circulation pipeline directly introduces the cutting fluid into the water tank, and the cutting fluid is not filtered and precipitated during the recovery process, the cutting fluid contains more impurities, which is easy to clog the pipeline. The current filtering devices on the market can only filter larger iron chips. Some relatively fine impurities such as metal powder generated during the processing cannot be completely filtered, which not only affects the service life of the cutting fluid, but also easily causes clogging of the cutting fluid circulation pipeline, affecting processing. Utility Model Content

[0005] The purpose of the utility model can be achieved through the following technical scheme: a cutting fluid filtering device, a sedimentation tank, a liquid storage tank, a first water pump is provided on the sedimentation tank, the water outlet of the first water pump is connected to a bag filter, the liquid outlet of the bag filter is connected to a magnetic filter assembly, the liquid outlet of the magnetic filter assembly is connected to the liquid storage tank, a second water pump is provided on the liquid storage tank, the water outlet of the second water pump is connected to a single-core filter, and the single-core filter is connected to the cutting fluid circulation pipeline of the machine tool.
[0006] Preferably, the magnetic filtration assembly includes a shell, a magnetic roller, and a motor. The magnetic roller is rotatably arranged on the shell. An arc-shaped groove is provided at the bottom of the magnetic roller. A water inlet connected to the bag filter is provided on one side of the arc-shaped groove on the shell. A water outlet connected to the liquid storage tank is provided on the other side of the arc-shaped groove on the shell. The motor is used to drive the magnetic roller to rotate.
[0007] Preferably, a pressure roller is rotatably provided on the shell body and contacts the magnetic roller.
[0008] Preferably, a material guide plate is provided on one side of the magnetic roller, and a scraper is provided at one end of the material guide plate for contacting the magnetic roller.

[0010] Preferably, a chute is provided in the sedimentation tank, and a filter is drawn out of the chute.
[0011] Preferably, a liquid level sensor is provided in the liquid storage tank.
[0012] The beneficial effects of the utility model are as follows: the utility model first performs preliminary filtration on larger impurities in the cutting fluid through a sedimentation tank and a bag filter, and then absorbs the magnetic metal powder in the cutting fluid through a magnetic filter component, while the metal powder or other impurities that cannot be absorbed by the magnetic filter component are filtered through a single-core filter, thereby greatly improving the filtering effect of the cutting fluid, preventing the cutting fluid circulation pipeline of the machine tool from being blocked, and effectively extending the service life of the cutting fluid.
