Definitions

  • the invention relates to a device for separating magnetizable Parts made of pourable or flowable goods
  • the said good can be in any form, as is the case with industrial or other applications.
  • magnetizable parts possible are iron filings or any other material that are magnetic or can be magnetized.
  • a known device of this type comprises a chute, which in its upper area has an inlet for the material to be cleaned, and in an outlet for the cleaned, i.e. of magnetizable particles free goods, as well as an outlet for the magnetizable particles.
  • a chute which in its upper area has an inlet for the material to be cleaned, and in an outlet for the cleaned, i.e. of magnetizable particles free goods, as well as an outlet for the magnetizable particles.
  • the tubes each contain a magnetic rod.
  • the goods are fed into the shaft above. It fails through the grids.
  • the magnetizable particles are thereby Magnetic force held on the outer surface of each tube, so that good free of magnetizable particles falls further down and optionally through another grate where another Cleaning takes place.
  • the outer surface of the pipes After a certain period of time, the outer surface of the pipes a layer of magnetizable particles is formed. Then they will Magnetic rods with the help of a common bracket in the axial direction pulled out the pipes. With this axial movement of the magnetic bars also migrate those deposited on the outer surface of the pipe in question Particles in the same direction, i.e. to the one end of that Tube where they drop due to a lack of magnetic force.
  • the method has the following disadvantage: the removal of the above the magnetizable particles sitting on the tubes is a discontinuous one Process. During this process, the pipes in question fall for the Deposition process. You can now see all pipes during one free from magnetizable particles for a certain period of time. This means, that the entire cleaning process is interrupted for this period. Part of the pipes can also be freed of magnetizable particles, and run the cleaning process on the remaining number of pipes. This means that the cleaning process only with reduced throughput can be carried out. Both types of cleaning are disadvantageous.
  • US-A-2 913 113 discloses an apparatus for depositing magnetisable Waste particles. According to this document, a powered, helical magnet inside a rotating driven cylindrical Bowl provided. The known features from this document are in Preamble of claim 1 summarized.
  • the invention has for its object a device of the type mentioned to be designed such that the removal of magnetizable particles, the have deposited on the outer surfaces of the pipes without Impairment of the cleaning process can be carried out.
  • the inventor has followed a very elegant path.
  • By turning the Magnetic rods with helically arranged magnets inside the fixed pipe finds a continuous discharge of magnetizable particles on the outer surface of the tube instead.
  • the particles namely migrate according to the circulation of the helically arranged Magnets along the outer surface of the pipe in question and fall on End of the pipe into a separate shaft for iron particles. in the The area of this shaft is non-magnetic
  • the deposition process is thus done by removing the magnetizable Particles in no way affected.
  • the device shown schematically in Figures 1a and 1b comprises a Drop shaft 1. This has three grids 2, 12, 22 arranged one above the other on. Each grate comprises several tubes 3. Each tube encloses one Coil magnetic rod 4.
  • Each tube 3 and the associated coil magnetic rod 4 are mutually arranged coaxially.
  • the tubes 3 are fixed, and the Coil magnetic rods continuously turn around during operation their own longitudinal axis.
  • the helical magnetic rods can be seen more clearly from FIGS. 2, 3 and 4.
  • each coil magnetic rod comprises a shaft 4.1.
  • the shaft 4.1 carries a continuous helix 4.2. She also wears one Variety of magnets 4.3. The magnets are between each Gears of the helix 4.2 arranged.
  • the wave 4.1 of everyone Helical magnetic rod 4 is driven at one end. The drive is not shown here.
  • each coil magnetic rod 4 is enclosed by a tube 3.
  • the magnets generate magnetic fields. Please refer the symbols + and -.
  • the shaft 4.1 is made of steel St37.
  • the device according to the invention works as follows:
  • the good to be treated is a product of the Sugar industry. It is a powdery good and contains iron particles. This good is shown in FIG. 1 at the top of the chute 1 shown there located inlet 1.1 supplied. It falls through the grates 2, 12, 22 and occurs in a largely purified form, i.e. without the iron particles, on Outlet 1.2 out.
  • the bars comprise each the fixed tube 3 and the inner one Coil magnetic rod 4.
  • the iron particles are separated by the magnetic Fields held on the outer surface of the fixed tubes.
  • the coil magnetic rod is non-magnetic.
