Problems solved by technology

[0003] With the increase in the number of cars, the problem that arises is that more and more car components are lost, and most of the car components are electronic components, especially some waste circuit boards with electronic components, and even scrapped cars. Other components, whose components are complex, will cause serious pollution to the surrounding environment and put a lot of pressure on environmental protection

Embodiment 1

[0034] The invention discloses a device for separating low-value substances and precious substances in scrapped vehicles. machine D, vibrating screen E and eddy current separator F, wherein:

[0035] refer to figure 1 As shown, the scissor lift platform A lifts scrapped cars and sends them into the feed port B1 of the twin-shaft shredder B.

[0036] refer to figure 2 As shown, the application principle of the double-shaft shredder B is that two sets of rotary cutterheads B2 composed of high-grade alloy steel shear each other to shred various soft and hard materials, including scrap automobile materials. Strong force, sharp blade, capable of crushing with high efficiency. It mainly adopts a combined structure frame with extra-thick plate precision processing, and its caliber is large, so it can safely input large-scale raw materials such as scrapped cars.

[0037] refer to image 3 As shown, the control crusher C is connected to the twin-shaft shredder B through the conve...

Embodiment 2

[0043] refer to Figure 5 As shown, compared with Embodiment 1, the difference is that it further includes a sampling device G for sampling the debris of scrapped automobiles, which is connected with the eddy current separator, which includes a stocker 1. The main material pipeline 2, the sampling pipeline 3, the crushing device 4 and the sampling bucket 5, in which:

[0044] The stocker 1 is used to store the slag of scrapped automobiles after crushing and sorting. In this embodiment, it is a storage hopper, and a main discharge port 11 is provided below it. The main discharge port 11 is connected with the main material The pipes 2 are connected; the side of the storage hopper is provided with a side discharge port 12; a scraper (not shown in the figure) is also provided in the storage hopper, and a driving device 13 is also provided on the storage hopper. In this embodiment, The driving device 13 is an electric motor, which can drive the scraper to rotate continuously in th...

Embodiment 3

[0049] refer to Figure 6 Shown, compared with embodiment two, its difference is:

[0050] It further includes a sample storage assembly, an observation assembly and a pulverizer 8, wherein:

[0051] The sample storage assembly includes sample storage hoppers 61, 62; the sample storage hopper 61 is provided with a sample discharge port 611 below, and the side is provided with a sample side discharge port 612; the sample storage hopper 61 is also provided with a driving device 613 and a The scraper (not shown in the figure) inside is constantly rotated under the drive of the driving device 613 . Similarly, a sample outlet is also provided below the sample storage hopper 62, and a sample side outlet (not shown in the figure) is provided on the side, and a driving device 623 and a scraper (not shown in the figure) are arranged on it. not shown), the scraper is driven by the driving device 623 to rotate continuously. In this embodiment, the driving devices 613, 623 are motors. ...

Abstract

The invention discloses a method and a device for separating low-value substances from valuable substances in a scraped car. The method comprises the following steps: (a) lifting the scraped car by a fork-type lifting platform, and feeding the scraped car into a top feeding hole of a double-shaft tearing machine; (b) tearing the scraped car by the double-shaft tearing machine, and then transporting the scraped car to a feeding hole of a control crusher through a conveyor belt; (c) throwing the scraped car into the control crusher for crushing, wherein the granularity of the crushed car material is controlled at 2cm to 5cm; (d) conveying the crushed car material into a magnetic separator so as to separate an iron magnetic substance; (e) conveying the car material without the iron magnetic substance into a vibration sieve for vibrating; (f) conveying the vibrated car material into a vortex separator for separating copper and aluminum. By the device and the method, the scraped car can be well crushed, the low-value substances such as iron, copper, aluminum and plastics in waste electronic elements of the scraped car can be efficiently separated, the valuable substances such as rare precious metal can be concentrated, and the scraped car can be efficiently recycled.

Description

technical field [0001] The present invention relates to the technical field of electronic waste recycling, in particular to a method and device for separating low-value substances and precious substances in scrapped cars. Background technique [0002] In recent years, with the rapid development of electronic technology, a large amount of electronic waste has been generated. In particular, since the 1980s when private cars began to appear in China, the number of private cars has continued to increase. As an emerging car country, China has become the world's largest car producer and the largest new car market in 2011. also expanded rapidly. [0003] With the increase in the number of cars, the problem that arises is that more and more car components are lost, and most of the car components are electronic components, especially some waste circuit boards with electronic components, and even scrapped cars. The components of other components are complex, causing serious pollutio...
