Safety issues in the use of metal detection sorters

The metal detection sorter is mainly composed of a detecting part and a rejecting part, and applies the principle of electromagnetic induction to detect the metal. All metals, including iron and non-ferrous, have high detection sensitivity. The entry of ferromagnetic metal into the detection area will affect the distribution of the magnetic field lines in the detection area, which in turn affects the magnetic flux in a fixed range. When the non-ferromagnetic metal enters the detection area, the eddy current effect will be generated, and the magnetic field distribution of the detection area will also change. When the metal impurities pass, the product alarm signal will be sent to the rejecting part, and the partial flap will be swung left and right to eliminate the inclusion. A product of metal impurities, thereby achieving complete separation of metal impurities.

Metal detection sorter safety in use

1, the direction of use

This equipment is mainly used in the plastics industry as well as in the food and chemical industries.

This equipment is designed for small pellets (such as powder or granules) that fall freely in vertical lines. The inlet should be connected to the hopper or pipeline. This equipment should be protected from vapor, dust or similar substances as this may affect the PVC. The insulation of the wires.

2, dangerous warning

A mains power supply is connected to the MSG3.3 electrical box, which is connected to external AC power, so there is a hazard warning in the door of the electrical box.

When the power supply is energized and the air supply is connected, it is very dangerous to open the cover of the equipment. Therefore, there is a danger warning inside the metal detection sorter.

The height of the entrance and exit of the metal detection sorter is 80mm, and the hand can easily touch the exit of the valve. Therefore, there is a danger warning on the discharge port of the metal detection sorter.

The cover can protect the operator from injury. To open the cover for repair or maintenance, please refer to 4.4

3. Dangers that may occur in places where there is no danger warning.

In the absence of a hazard warning, there may be a possibility of injury from static electricity or pneumatic components.

4 Safety precautions for operation and maintenance

When the metal separator works, the cover and the electrical door should be closed to avoid the danger of injury and contamination of the machine, and prolong the service life. All warning signs attached to the machine must be clearly visible, for no reason. Torn off, the inlet and outlet should be connected by a tube with a diameter of 70mm, and the outlet tube should be 90cm long. Please read the relevant regulations if you can detect explosive materials. If you are repairing electrical and electronic components or repairing pneumatic components, be sure to cut off the power supply and air supply. This operating manual should be easy to obtain and clear.

Only trained technicians are allowed to operate and service this unit.

5 Potential danger

After the electric switch is turned off, the electric box may be in a live state due to the external power supply still connected.

In addition, due to the presence of a compression cylinder, the pneumatic components will still operate after the air supply is cut off.

6 Unauthorized

No modification or repair work is allowed without authorization from the company.

7 Unallowed operations

Operations outside the scope of use of 1 are not allowed

Operations outside the scope of the technical parameters are not allowed.

It is not allowed to detect corrosive materials and explosive materials.
