Embodiment 1

[0039] A recycling device for waste circuit boards provided in this embodiment has a structure such as Figure 1-4 shown.

[0040] Such as figure 1 As shown, the waste circuit board recovery equipment includes a crushing mechanism 1, a sorting mechanism 2, a mixing mechanism 3 and a pelletizing mechanism 4 arranged in sequence.

[0041] Wherein, the crushing mechanism 1 includes a slitting chamber 11 and a crushing chamber 12 arranged vertically. The discharge opening below the crushing chamber 12 faces the conveyor belt 21 . The other end of the conveyor belt 21 extends above the feed opening 31 , and an electromagnet 22 is arranged above the conveyor belt 21 .

[0042] The feeding port 31 communicates with a mixing chamber 32 , and the other end of the mixing chamber 32 is provided with a detachable die 34 . An outlet 35 is provided on the die head 34 .

[0043] The cutting knife 41 is controlled by the pelletizing motor 42 and sweeps the outlet intermittently.

[0044...

Embodiment 2

[0058] A method for recycling waste circuit boards, comprising the steps of:

[0059] S1. Crushing waste circuit boards into crushed materials with a particle size of no more than 80 meshes;

[0060] S2. Removing the metal material in the crushed material by magnetic field separation to obtain resin ring fiber powder;

[0061] S3. Mix the resin ring fiber powder with the reinforcing agent and plastic to obtain the glass-plastic mixture. The ratio of the mixed mass of the three to the total mass is 35% to 50% of the plastic, the reinforcing agent is not less than 15%, and the rest is resin ring fiber pink;

[0062] S4, heating the glass-plastic mixture to obtain the glass-plastic mixture particles;

[0063] S5. Obtain glass-plastic handicrafts by means of hot pressing, extrusion molding, and the like.

[0064] Wherein, the resin ring fiber powder obtained in S2 is air-dried so that the moisture content of the resin ring fiber powder does not exceed 6%. During the separation...

Embodiment 3

[0066] A composite floor, including the glass-plastic layer prepared by the recycling method in the second embodiment.

Abstract

The invention discloses equipment and a method for recovering waste circuit boards, and relates to the technical field of electronic waste recovery. According to the equipment and the method for recovering the waste circuit boards, a crushing mechanism, a sorting mechanism, a mixing mechanism and a dicing mechanism are provided, wherein the crushing mechanism is used for crushing the waste circuit boards; one end of the crushing mechanism is a feeding port for putting the waste circuit boards, and the other end of the crushing mechanism is a discharging port for flowing out the crushed materials; the sorting mechanism is over against the discharging port to bear the crushed materials and convey the crushed materials to the next station; an electromagnet is arranged along the conveying route of the crushed materials; the mixing mechanism comprises a feeding port for bearing the metal-removed materials; the feeding port communicates with a mixing chamber; an outlet of the mixing chamber is formed in a mould head; and the dicing mechanism comprises a cutter capable of sweeping the outlet intermittently and a dicing motor for driving the cutter to move. According to the equipment and the method for recovering the waste circuit boards, the waste circuit boards can be recovered to prepare reusable glass plastic mixed particles.

Description

technical field [0001] The invention relates to the field of electronic waste recycling, in particular to a recycling device and a recycling method for waste circuit boards. Background technique [0002] In order to solve the increasingly serious problem of environmental pollution caused by waste electronic products in my country, the State Council promulgated Order No. 551 on February 25, 2009, "Regulations on the Administration of Recycling and Disposal of Waste Electrical and Electronic Products", which will come into force on January 1, 2011. come into force. However, a set of production lines (including equipment and technology) that start from the dismantling of electronic waste to the application of all wastes has not been established in China, especially after the waste circuit boards are crushed and recovered metals such as copper, the remaining resin Cyclofiber powder is discarded arbitrarily. [0003] The resin ring fiber powder can be made into glass-plastic mix...
