Problems solved by technology

[0007] The above treatment scheme 1 solves the problem of utilizing the internal metal of the waste ceramic resistor, but incineration will produce a large amount of toxic gas and cause secondary pollution to the environment
Solution 2 uses direct landfill for ceramic resistors, which not only causes waste of resources but also pollutes the landfill soil. In short, landfill and incineration not only pollute the environment, but also waste resources

Embodiment Construction

[0042] The method of dismantling and recycling waste ceramic resistors is as follows: the ceramic resistors are mainly composed of ceramic body and tin-plated copper-iron alloy pins, and the waste ceramic resistors are put into the rolling crusher through the feeding hopper 11 and the feeding regulating valve 12 2, the rolling crusher 2 is equipped with a plurality of pairs of rolling rollers or drums 5, and each pair of rolling rollers or drums is opposite to the rolling rollers or drums to roll and roll waste ceramic resistors, and the rolling rollers Or the drum is connected and driven by the drive motor 7, and a vibrating screening machine is installed under the rolling roller or the drum. The vibrating screen of the vibrating screening machine is installed at an inclination at a certain angle. Install a vibrating motor, and connect the vibrating motor to vibrate. After the waste ceramic resistors are rolled by the rolling rollers or rollers, the ceramics are crushed, while...

Abstract

The invention relates to method and equipment for disassembling waste ceramic resistors and recovering resources. In the invention, waste ceramic resistors are put into a grinding type crusher from a hopper and a feed regulation valve, wherein the grinding type crusher is internally provided with a plurality of pairs of grinding rolling shafts or rollers for grinding the waste ceramic resistors; a vibration screening machine is arranged below the grinding rolling shafts or the rollers; a vibration screening net is obliquely arranged and supported on a stand by a spring; a vibration motor is arranged below the vibration screening net; after the ceramic resistors are crushed, a mixture of ceramic powder and copper and iron pins is formed, falls on the vibration screening machine and sieved by the vibration screening net; and a steel plate plane ceramic powder collecting layer is arranged below the screening net, and an oblique discharge hole of the screening net is used for collecting the copper and iron pins for recovering metal resources. In the invention, a physical method is adopted to crush without secondary pollution, which protects the environment, saves energy and has good metal resource recovery and utilization effects.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a method and equipment for dismantling waste ceramic resistors and recycling resources. Background technique: [0002] After my country entered the peak period of discarding household appliances, the recycling and disposal of waste electronic products was quickly put on the agenda. It is reported that after my country enters the peak period of electric appliance waste, it is estimated that 5 million TV sets, 4 million refrigerators, and 6 million washing machines will be scrapped every year. In the next 5 to 10 years, the amount of scrapped computers will also reach more than 5 million sets per year. At the same time, the industry of e-waste recycling and reuse has mushroomed. Used e-waste is mainly composed of plastics, printed circuit boards (PCBs), glass and metal brackets. Among them, the printed circuit board (PCB) occupies the main body of electronic was...
