Device and method for automatically separating three or more than three materials

Abstract

The invention relates to a device and a method for automatically separating three or more than three materials. An air injection-type automatic separation device provided by the invention mainly comprises an air injection separation module group, an air pressure loop and a material tank assembly; the air injection separation module group is formed by mounting a plurality of air injection separation modules side by side; each air injection separation module consists of an air injection assembly, an angle adjustment mechanism, a height adjustment mechanism and a machine frame. Nozzles of each air injection assembly are arrayed on a mounting plate in circumference; the opening and closing of each nozzle are independently controlled according to the sizes of the materials, and are assisted by angle control, so that the air injection separation modules can adapt to the separation requirements of the materials, such as flake-shaped materials, spherical materials and block-shaped materials, with different shapes and sizes. According to the device, the materials with different element types, shapes, and sizes are blown into corresponding material tanks of the material tank assembly by controlling the opening and the closing of the nozzles, the air injection angles and the air flow pressure values at air injection outlets during a material falling process according to the element type information and the position information of the materials analyzed by a material identification system; therefore, the mixed materials are separated automatically.

Description

technical field [0001] The invention relates to a device and a separation method for automatically separating three or more materials, belonging to the field of automatic material separation. technical background [0002] Metal is an indispensable basic material and important strategic material for the national economy, people's daily life and national defense industry. With the development of my country's national economy and the improvement of people's living standards, the continuous emergence of new products and the shortening of product replacement cycles have led to a rapid increase in the number of waste products (such as scrapped cars, mechanical equipment, home appliances, etc.), and a large number of scrap metals are produced. . Scrap metal recycling is an effective means to save energy and reduce environmental pollution. [0003] Scrap metal crushing, sorting and recycling are currently the most advanced scrap metal recycling methods in the world. After the wast...

Problems solved by technology

[0004] With the development of eddy current, photoelectric separation technology and X-ray separation technology, although various metals in the mixture can be accurately identified, but limited by the material separation technology, it is impossible to realize the separation of various mixtures by category at one time.

Although the jet separation technology has been applied to the metal sorting machine, it can only separate the multi-metal mixture into two types at one time, and it is necessary to replace different jet modules before sorting according to the size range of the material, which not only makes the The sorting process becomes complicated, which also leads to the increase of sorting cost and the reduction of sorting benefit

In addition, the nozzle of the currently used jet-type automatic separation device adopts a fixed separation plate structure with porous single-row distribution. There will be a phenomenon that some materials cannot be separated
