Q-Mag® magnetic separator

Photo of a Q-Mag® magnetic separator.Q-Mag® is the solution to effectively use magnets in your process. Remove chips and metal particles from your coolant or cleaning fluid easily,  without having to clean the magnet time and again. With Q-Mag® it is all automatic!

The Q-Mag® uses a single, rotating magnet in combination with a fixed mounted Archimedes screw. This creates a screw conveyor which continuously transports anything deposited on the surface of the magnet to the bottom end. Metal particles do not get a chance to build up on the magnet and cover it completely. The magnetic field  can stretch out fully into the medium circling around the magnet at all times.

The medium spirals around the magnet, that way bringing every particle within the magnetic field for at least 2 seconds. The result is an extremely efficient separation of even the finest magnetizable particles.

The sludge chamber is emptied automatically, without interrupting the flow or removing the magnet. The separation continues all the time. A sensor detects when the sludge chamber is full and starts emptying it, thereby discharging only very little medium with the sludge. There is no need for further de-watering of the sludge.

 

 

 

Features.

  • Fully automatic separation: particles attracted by the magnet are continuously transported into the sludge collection chamber.
  • Efficient: the medium spirals around the magnet, bringing all particles into the magnetic field for more than 2 seconds.
  • Effective: the magnet is kept clean automatically, ensuring the magnetic field always fully extends into the fluid.
  • Continuously: the sludge collection chamber is emptied automatically, without interrupting the normal operation.
  • Minimal waste: the sludge is very concentrated and separated with minimal fluid.

Construction.

The Q-Mag® construction.The magnet is shown in the center (3), fully enclosed by the Archimedes screw (2).

The fluid enters at A and spirals around the magnet (blue arrows) upward to outlet B, bringing every particle within the magnetic field for at least 2 seconds.

The rotation of the magnet, in combination with the Archimedes screw, creates a screw conveyor which continuously transports the particles on the surface of the magnet to the bottom end where they fall into the collection chamber.

A sensor detects when the sludge chamber is full and starts the sludge discharge sequence.

Sludge discharge sequence.

The Q-Mag® operating principle.

The above diagram shows the operating principle:

  1. The sludge chamber is empty: valve a is open, valve b is closed.
  2. The sludge falls from the magnet into the sludge chamber, onto valve b.
  3. The sensor detects that the sludge chamber is full; valve a is closed
  4. Valve b is opened and the sludge chamber is emptied by blowing out nay material, using pressurized air.
  5. Valve b closes and valve a can be opened again.

Configuration.

The Q-Mag® configuration.The Q-Mag® is available in various configurations. Sludge chamber inlet and outlet valve, sludge sensor and purge valve are always part of the configuration, as wel as the drive for the magnet.

Depending on the requirements the system can be fitted with a control panel or a terminal box. An other option are the valve position sensors on the sludge chamber inlet and outlet valves which allow monitoring of the valves open or closed status and is used to prevent both valves from being (partially) open at the same time.

The configuration can be completed with a feed pump or an inlet shut-off valve. Control of these items is included in the standard control system. It is also possible to install the Q-Mag® on the suction side of a pump. In that case it is important to make sure air can not remain captures in the piping. An (automatic) venting system may be required.

In specific situations, inlet and outlet can be exchanged, with the medium entering at B and exiting a A. This can be advantages in situations where significant amounts of metal particles are captures in a light phase, like oil.

Options.

The Q-Mag® can be supplied with various options:

  • Control system.
  • Terminal box.
  • Inlet shut-off valve.
  • Feed pump.
  • Automatic venting.
  • Valve position sensing.
  • Mounting brackets for wall mounting.
  • Stand for floor mounting.
