Active pulsating air flow sorting system

Abstract

The invention relates to an active pulsating air flow sorting system. The system comprises a sorting air flow generating segment, a feeding segment, a first discharging segment, a second discharging segment, a dust removing segment and a sorting segment; the sorting air flow generating segment is horizontally arranged at the bottom; a feeding machine is arranged on the feeding segment; a feeding hopper is connected with the top of the feeding machine; a discharging port of the feeding machine is inwardly connected with the middle part of the sorting segment; the first discharging segment is arranged at the bottom of the sorting segment; the second discharging segment is a cyclone separator; an air inlet of an air inducing machine of the dust removing segment is connected with an air outletof the cyclone separator via an air ventilating bent pipe; and the sorting segment is a vertically arranged air duct. According to the active pulsating air flow sorting system, a special structural design is made based on size and specification of copper foil and aluminum foil contained in waste battery broken products, sorting and integral recycling of the two kinds of materials are realized, and the recycling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a mixture airflow sorting system, in particular to a sorting system using aortic flow. Background technique [0002] In the field of waste product recycling, in addition to breaking large products into small parts, it is also very important to sort different parts and fragments, so as to gather the same attributes and materials together. It is convenient for recycling, and the airflow sorting is to use the different densities of the fragments to classify and recycle the fragments of different materials. [0003] In the field of scrapped car recycling, the recycling of steel structure parts such as car shells is very high, but it is difficult to recycle the batteries contained in scrapped cars; It is also very important to classify and recycle the metals contained in it, especially the battery is rich in copper foil and aluminum foil, both of which are non-ferrous metals, and it is difficult to achieve effective separation by c...

Problems solved by technology

[0003] In the field of scrapped car recycling, the recycling of steel structure parts such as car shells is very high, but it is difficult to recycle the batteries contained in scrapped cars; It is also very important to classify and recycle the metals contained in it, especially the battery is rich in copper foil and aluminum foil, both of which are non-ferrous metals, and it is difficult to achieve effective separation by conventional magnetic separation and other technologies

[0004] Chinese Patent Publication No. CN109894364A discloses a kind of airflow sorting and screening device for waste lithium battery recycling and processing, which discloses a sorting device using airflow as a sorting medium, but it is mainly for recycling the inclusions in the whole pack of batteries Screening of waste paper, dust, wood and other impurities, does not involve the sorting work after the battery is broken

[0005] In addition, the Chinese patent publication number is CN107790382A, a lithium battery crushing material gravity separation system, and the Chinese patent publication number is CN110918459A, a waste lithium battery sorting device based on the Coanda effect that automatically adjusts the air flow, and the Chinese patent publication number is CN209349045U A sorting equipment for lithium batteries after crushing, and a dry recovery system for waste power lithium batteries with a Chinese patent publication number of CN110581322A. Airflow separation is used, but the airflow separation used is generally based on the specific density of the material, setting a specific airflow size, so as to achieve different distances for settlement; but this type of technology is limited by the size of the material after crushing , the blowing force received is different, and the settlement distance produced by the cooperation with gravity is related to the size of the settlement distance, which will produce a parabolic settlement area, and there will be a certain cross-overlapping area, and the sorting is not thorough
