Problems solved by technology
[0002] The metal products industry will produce a large amount of metal dust in the process of mechanical drawing and physical denaturation of linear metal materials, and the high and low voltage electrical control cabinets in the production equipment and the electrical equipment with computer program control are most likely to be caused by the concentration of metal powder. The high dust concentration in the air will cause a short circuit in the electrical part of the circuit, sparks will be generated and the entire set of electrical and computer control parts will be burned instantly, causing the entire set of equipment to be paralyzed, and the electrical control part cannot be repaired, causing great economic losses. Replacement of new electrical controls The equipment needs to stop the production line, and similar failures often occur in production practice. This invention is specially designed to protect the electrical control system from the hazards of metal dust and achieve the purpose of safe, stable and trouble-free production and operation of production equipment.
