Multifunctional separator for recycling of waste fluorescent lamps

The invention relates to a multifunctional separator for recycling of waste fluorescent lamps and belongs to the technical field of mechanical equipment for recycling of fluorescent lamps. The multifunctional separator comprises a separator shell, a vibrating groove, an electromagnet, a rotating air cylinder, a filter sieve and the like, wherein a feeding cylinder is arranged at the top of the separator shell; the rotating air cylinder is arranged at the top in the separator shell; the electromagnet is arranged on a piston of the air cylinder; the vibrating groove is formed below the feeding cylinder and the electromagnet; a fan port is arranged at one end of the vibrating groove; and the filter sieve is arranged at the other end of the vibrating groove. By adoption of the vibrating groove, the filter sieve and the electromagnet, broken materials can be separated quickly. The multifunctional separator solves the problem that waste materials are recycled difficultly because the conventional broken materials can not be separated effectively and quickly. When the broken materials are separated, fluorescent powder contained in the broken materials enters a fluorescent powder collecting device from a fluorescent powder collecting port to be collected, so that the environmental pollution is avoided and the multifunctional separator is particularly applicable to recycling of the waste fluorescent lamps.
