Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid purification, in particular to a multi-gradient magnetic mud adsorption device. Background Art

[0002] During the machining process, a large amount of cutting fluid is used to reduce friction, dissipate heat and remove chips. During the circulation process, these cutting fluids are inevitably mixed with magnetic particles such as iron filings and other impurities and colloidal substances, forming magnetic mud with complex composition. The accumulation of magnetic mud will not only block the pipeline and accelerate equipment wear, but also seriously affect the performance of the cutting fluid. Therefore, it is very important to filter and remove the magnetic mud in the cutting fluid efficiently and reliably. The existing magnetic mud filter generates a magnetic field through a magnetic drum to adsorb magnetic particles in the cutting fluid. However, the generated magnetic field strength is single and cannot adsorb magnetic particles of different particle sizes or magnetic susceptibility. It is also impossible to achieve adsorption and filtration of other non-magnetic impurities in the magnetic mud. Utility Model Content

The magnetic mud adsorption component 2 includes a box body 21, and the outer surface of the box body 21 is provided with an inlet channel 25 and an outlet channel 26. The inlet channel 25 and the outlet channel 26 are used for the inflow and outflow of cutting fluid. A rotating shaft 22 is rotatably connected in the box body 21, and a magnetic drum group is fixed on the rotating shaft 22. The magnetic drum group includes at least one electromagnetic coil magnetic drum 23 and at least one permanent magnet magnetic drum 24. The permanent magnetic material used by the permanent magnet magnetic drum 24 is neodymium iron boron permanent magnet or samarium cobalt permanent magnet; the drive component 4 includes a drive motor 41 and a motor base 42 fixed on the frame 1. The drive motor 41 is fixed on the motor base 42. The output shaft of the drive motor 41 is fixed to the rotating shaft 22. The electric control box 3 is used to adjust the electromagnetic coil magnetic drum 23, a magnetic field size is determined, and a magnetic mud transport assembly is fixed in the box 21, and the magnetic mud transport assembly is connected to the magnetic drum group. The magnetic mud transport assembly is used to send the magnetic mud adsorbed by the magnetic drum out of the box 21, and the magnetic mud transport assembly includes a fixed shaft 51 fixed inside the box 21, and a plurality of rollers 52 are rotatably mounted on the fixed shaft 51. The number of rollers 52 is the same as the number of magnetic drums in the magnetic drum group. The rollers 52 are mounted one-to-one on the upper ends of the electromagnetic coil magnetic drum 23 and the permanent magnet magnetic drum 24. A plurality of discharge channels 53 are integrally provided in the box 21, and the inlet ends 531 of the discharge channels 53 are connected one-to-one with the rollers 52, and the outlet ends 532 are located on the outer surface of the box 21.

[0018] The magnetic drum assembly in this embodiment includes four electromagnetic coil magnetic drums 23 and one NdFeB permanent magnet magnetic drum.

[0019] In this embodiment, the control of the magnetic field size of the electromagnetic coil drum 23 is achieved by using an existing control module.

The strong magnetic field quickly absorbs large magnetic particles and forms magnetic mud clusters on the surface of the electromagnetic coil drum 23.

The clean cutting fluid after multi-gradient magnetic mud adsorption flows out from the outlet channel 26; the driving motor 41 drives the magnetic drum group to rotate through the rotating shaft 22. When the magnetic drum that absorbs magnetic mud rotates to the top, the roller 52 presses the magnetic mud. The magnetic mud enters the inlet end 531 of the connected discharge channel 53 as the magnetic drum rotates, and the magnetic mud slides into the collection channel 54 along the inclined discharge channel 53.
