Embodiment approach

[0061] The present invention provides a preferred embodiment of a complete set of processing equipment for recycling waste circuit boards, see figure 1 , mainly including a pretreatment device, a cracking and oiling device, a crushing / separating device, and a dust removal device. The above components and their connections are described below.

[0062] A pretreatment device, the inlet of which is connected to the outlet of the feed device, is used for pretreatment of the waste circuit boards from the feed device or electronic waste containing waste circuit boards. Specifically, the pretreatment device includes: a first pretreatment device and / or a second pretreatment device; wherein, the first pretreatment device includes a tin removal machine 1, and the tin removal machine 1 is used to pretreat waste circuit boards, that is, Tin and electronic components are separated from waste circuit boards to obtain bare circuit boards, which can be directly sent to the cracking and oiling...

Embodiment

[0087] The complete set of processing equipment for recycling waste circuit boards provided by this preferred embodiment has a structure such as figure 1 As shown, the equipment mainly includes the following devices: tin removal machine, magnetic separator, chain crusher, corrugated screening tank, thermal decomposition tank, catalyst tank, cooling device, oil storage tank, gas burner (specifically combustion furnace) , Hammer Mill, Air Jig Separator, Electrostatic Separator, Belt Conveyor; the above devices are all commercially available products, details are as follows:

Abstract

The invention provides complete treatment equipment and a treatment method for waste circuit board recycling. The equipment comprises a pretreatment device, a cracking and oilation device, a crushing / sorting device and a dust removal device, wherein an inlet of the pretreatment device is connected with an outlet of a charge device for pre-treating the waste circuit board or electronic waste containing the waste circuit board from the charge device; an inlet of the cracking and oilation device is connected with an outlet of the pretreatment device for performing cracking and oilation treatmenton the waste circuit board material output by the pretreatment device; an inlet of the crushing / sorting device is connected with a solid material outlet of the cracking and oilation device for furthercrushing and sorting a metal and glass fiber mixture output by the cracking and oilation device; and an inlet of the dust removal device is separately connected with the pretreatment device and a dust outlet of the crushing / sorting device for treating dust to realize up-to-standard emission. The equipment is good in decomposition effect, is safe, saves labor power, can continuously operate for 120 hours, is low in energy consumption, is high in yield, is free of pollution, and has a metal recovery rate of 95%-98%.

Description

technical field [0001] The invention relates to a complete set of processing equipment and a processing method for recycling waste circuit boards, especially a complete set of processing equipment and a processing method for harmless waste circuit boards, belonging to the field of non-ferrous metal reproduction. Background technique [0002] my country is a big producer of electrical and electronic products, but also a big consumer.
