Problems solved by technology
However, these methods can only remove non-metallic impurities, separate magnetic metals from non-magnetic metals, or separate heavy metals from light metals, but there are still problems. For example, in the case of mixed light metals such as aluminum and magnesium, it is difficult to have efficient and suitable means of separation
[0004] However, some of the current jet-type separation equipment adopts a simple air flow and interruption method, which can only complete the separation of two types of scrap metal, and the efficiency is relatively low.
Especially when the position, shape, and size of the scrap metal on the conveyor belt change, the separation device does not have the ability to adapt itself, and cannot take more adaptive measures. It is prone to missed blowing, wrong blowing, etc., which eventually leads to inability to efficiently and accurately Separation of scrap metal

Embodiment Construction
[0033] The present invention will be further described below in conjunction with accompanying drawing.
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as figure 1 As shown, the scrap metal is on the conveyor belt 1 and passes through the identification system 2 to obtain the shape, size, type and position information of the scrap metal on the conveyor belt 1, so the air pressure module 3 generates airflow with corresponding pressure and flow rate, and the air injection module 4 carries out corresponding The adjustment of the angle and the cross-sectional area of the nozzle finally blows the scrap metal efficiently and accurately into different areas of the storage module 5 to achieve the purpose of self-adaptive separation.
[0036] Such as figure 2 As shown, the air pressure module 3 is composed of an air source 6 , a proportional pressure reducing valve 7 , a one-way val...

The invention provides a self-adaptive waste metal efficient separation device and method. According to the device, a servo motor is used for adjusting the rotation angle and the pitching angle of a nozzle, and corresponding self-adaptive adjustment can be carried out on waste metal with different shapes and positions. A proportional pressure reducing valve and a proportional flow valve are utilized to generate separation gas flows with different pressure and flow, a ball screw mechanism is used on the nozzle to drive a nozzle baffle to move so as to adjust the sectional area of the nozzle, and the self-adaptive efficient separation of the waste metal is finally realized.
Description
technical field [0001] The invention relates to the field of automatic material sorting, in particular to an adaptive waste metal high-efficiency separation device and method. Background technique [0002] As my country's economy continues to grow rapidly, people's requirements for living standards are getting higher and higher, resulting in increasing demand for industrial products and shortening the replacement cycle. On the one hand, the industry’s demand for metal resources is increasing, and the mining of primary mineral metal resources will cause resource and environmental problems; on the other hand, there are problems in the recycling of metal resources in the waste products that are constantly being eliminated. This puts forward higher requirements for the recycling of scrap metal, and scrap metal is generally a mixture of various metals, dust, and impurities. How to separate these different types of scrap metal efficiently and accurately to facilitate further recyc...
