Definitions

  • the present invention relates to devices for magnetic separation of substances and relates in particular to magnetic filter separators.
  • a magnetic filter separator which contains working chambers with a filtering ferromagnetic filling, electromagnets with cores, which are provided with ferromagnetic plates, and nozzles for supplying the fluid to be cleaned and for removing the cleaned fluid (SU, A, 784894).
  • the required degree of cleaning of the fluids cannot be guaranteed, because the electromagnet cores, which bear against the chambers with their end faces, cannot magnetize the part of the ferromagnetic filling located in the axial region of each chamber to the required level.
  • the cores of the electromagnets are also arranged outside the working chambers. As a result, part of the magnetic flux generated by the electromagnets and scattered into the surrounding medium reduces the magnitude of the magnetic flux which is used to magnetize the ferromagnetic filling. This reduces the overall efficiency of the filter separator.
  • a magnetic filter separator comprising two via a connecting piece interconnected chambers, each of which is filled with a ferromagnetic filling, which is acted upon by a magnetic field generated by a magnetization system having a pair of cores and magnetic field sources arranged opposite one another, and one of which is a chamber with a nozzle for supplying the fluid to be cleaned and the other is provided with a nozzle for discharging the cleaned fluid (SU, A, 1025450).
  • the cores of the magnetization system are arranged outside the chambers, their side surfaces being in contact with the housings of the chambers.
  • the size of the magnetic flux which is conducted through this surface into the volume of the ferromagnetic filling is not sufficient for magnetizing the entire volume of this filling to the required level.
  • the area of the cores abutting the chambers makes up only part of the total surface area of the end portions of the cores abutting the chambers; this results in some of the magnetic flux generated by the electromagnets being scattered into the surrounding medium, thereby reducing the size of the magnetic flux to be used to magnetize the ferromagnetic filling and reducing the overall economy of the magnetization system and the filter separator.
  • the core parts arranged in the vicinity of the magnetic field sources are operated in the magnetic saturation operating state, while the core parts which are furthest away from the magnetic field sources are not magnetized sufficiently enough as a result of a drop in the magnetic potential acting along the cores.
  • the volume of the ferromagnetic filling, which is close to that of the mag Network field sources located most distant core parts is therefore not magnetized enough, which leads to a reduction in the degree of cleaning and the economy of the filter separator as a whole.
  • the present invention has for its object to provide an economical magnetic filter separator in which the cores of the magnetization system are arranged relative to the ferromagnetic filling such that thereby ensure the required degree of cleaning of this filling.

  • the end sections of the same name with respect to the magnetic poles of each pair of cores of the magnetization system are preferably to be accommodated in chambers in the volume of the ferromagnetic filling at the same depth.

  • Such an arrangement of the end sections of the cores also allows different directivity of the averaged magnetic lines of force to be formed over the volume of the ferromagnetic filling, namely a vortex-shaped directivity, which leads to a compensation of the magnetization of the zones of the ferromagnetic filling.
  • the magnetization system of the filter separator with a larger chamber diameter of 0.5 to 1.0 m and more, it makes sense to provide ferromagnetic bodies to exclude the zones with reduced values of the induction of the magnetic field.
  • the ferromagnetic bodies to exclude the zones with reduced values of the induction of the magnet fields can be formed in the form of cylinders.
