The invention relates to devices for thin separation liquid-disperse systems, in particular for the capture of ferromagnetic impurities arising from the depreciation of the elements of the hydraulic drive in the process.
Known magnetic separator for the regeneration of the magnetic fluid, containing the working chamber with curved walls, placed in the chamber of ferromagnetic filter the nozzle in the form of plates with clearances, magnetic system with reels of magnetic cores, inlet and outlet (A.S. no 1535634, IPC US 1/30. Publ. 15.01.1990. - Bul. №2).
The disadvantage of this analogue is that the regime of separation takes place only due to the magnetic field in the small gap between that, for large size of the device, has a small bandwidth magnetic liquid and solid phases of the ferromagnetic impurities. Large size analogue, complex, distributed magnetic systems, to apply in complex conditions of operation of hydraulic systems is virtually impossible.
Partially the drawbacks of the device are not in the known magnetic separator for thin separation liquid-disperse systems containing chamber with curved walls, inlet and outlet, but the camera is placed ferromagnetic filter cap, a magnetic system with coils and more curved pipes, United collector for removal of magnetic fluid (A.S. no 1219143, IPC US 1/02. Publ. 23.03.1986. - Bul. №11). The components of the magnetic fluid and this device can be derived from the main stream of liquid-disperse system, but without division of solid and liquid phases of magnetic fluid.
The disadvantage of the device is that it does not provide the desired mode solids separation of ferromagnetic material. Therefore, require an additional installation for separation of solids ferromagnetic material.
Of known technical solutions closest to claimed for the moment is the magnetic separator for thin separation liquid-disperse systems containing chamber with curved walls, inlet and outlet, but the camera is placed ferromagnetic filter cone with arch-like form (application for invention No 93010515/03, IPC US 1/02.
