specific Embodiment approach

[0022] The waste and old PCB board crushing and sorting system of the present invention, its preferred embodiment is:

[0023] Including dismantling unit, crushing unit, primary air separation unit, iron removal unit, grinding unit, fine iron removal unit, wind separation separation unit, high-voltage electrostatic separation unit, dust waste gas treatment unit, and central control unit;

[0024] In the dismantling unit, electronic components containing precious metals on the circuit board and electronic components with a height greater than 30mm are removed;

[0025] In the crushing unit, the disassembled circuit board is crushed to particles with a particle size of less than 2mm through two-stage crushing;

[0026] The primary winnowing unit separates non-metallic particles from the crushed material;

[0027] The iron removal unit performs a primary iron removal on the material after the primary winnowing;

[0028] The grinding unit grinds and pulverizes the material after...

specific Embodiment

[0061] Specific examples, such as figure 1 , figure 2 Shown:

[0062] 1. Dismantling the unit

[0063] The circuit board is on the dismantling workbench, manually remove electronic components containing precious metals and other electronic components with a height greater than 30mm (such as sockets, transformers, coolers, I / O slots, CPU slots, etc.) , and classified storage.

[0064] The disassembled waste PCB board enters the automatic electronic component removal machine through the conveyor; the electronic component removal machine is composed of a chuck separation knife and a fan. The circuit board enters the body and is automatically clamped. Under the action of the separation knife The circuit board and electronic components are separated, and the dust and smoke generated during the separation process are extracted by the fan to avoid environmental pollution. The separated circuit board and electronic components are sent to the vibrating screen by the conveyor, and t...

Abstract

The invention discloses a waste PCB (printed circuit board) crushing and sorting system. The waste PCB crushing and sorting system comprises a disassembling unit, a crushing unit, a primary air classification unit, a deferrization unit, a grinding unit, a fine deferrization unit, an air classification separating unit, a high-voltage electrostatic separation unit, a dust and waste gas disposition unit and a central control unit, wherein a circuit board is disassembled and crushed, and then is subjected to procedures such as primary air classification, primary deferrization, grinding, secondary deferrization, air classification separating and high-voltage electrostatic separation, and a copper-containing metal concentration with the purity of 99.5% is obtained. The waste PCB crushing and sorting system provided by the invention is used for recovering available resources in a waste PCB plate treating process, treating the waste PCBs in scales, efficiently recovers resources, and avoids the environment pollution.

Description

technical field [0001] The invention relates to a waste and old PCB board processing and recycling technology, in particular to a waste and old PCB board crushing and sorting system. Background technique [0002] With the continuous improvement of social living standards, the consumption of electronic products continues to increase, and the replacement rate and elimination rate of household appliances continue to rise. The total number of household appliances that enter the new generation every year, including TVs, washing machines, refrigerators, air conditioners, computers and other small household appliances, is in the About 20 million units, dealing with printed circuit boards in these waste electrical appliances, reducing environmental pollution and reusing resources has become a very substantial issue. [0003] The PCB board is a collection of glass fiber, resin, copper and tin. The metal content in the PCB board is about 40%. For the ever-increasing waste PCB boards a...
