Split type multi-roller multi-component high-gradient vibration magnetic separator in permanent magnetism

Abstract

The invention relates to a permanent magnetic midsplit type multi-roller multivariate high gradient vibration magnetic selector, which comprises a stander (12), a magnetic selection box body arrangedabove the stander (12) through a vibration reduction spring set (18), a plurality of permanent magnetic rollers arranged inside the magnetic selection box body, a feed hopper (22) positioned on the top of the magnetic selection box body and a feed discharging passage (17) positioned on the bottom of the magnetic selection box body. The vibration magnetic selector is characterized in that the permanent magnetic rollers are made from magnetic materials with different magnetic strengths; according to a two-dimensional matrix form, the plurality of the permanent magnetic rollers are arranged to construct a multivariate sorting magnetic field; the permanent magnetic rollers made from the magnetic material of the same type are positioned on the same plane; according to the magnetic strengths, the permanent magnetic rollers with different magnetisms are in deltaic alternate arrangement sequentially from top to bottom along the flowing direction of the materials; magnetic concentrating mediumgrooves with the same specification are arranged between the adjacent permanent magnetic roller layers in different layers and above the upper layer of the permanent magnetic roller layers; and the inside of each groove is provided with magnetic concentrating media with different types.

Description

technical field [0001] The patent of the present invention relates to a magnetic separation device, in particular to a permanent magnet split-type multi-roller multi-element high-gradient vibration magnetic separator. This magnetic separator is suitable for processing wide-grained powder materials containing a variety of different magnetic minerals. It can be used for wet separation, dry separation, and industrial sewage treatment. Background technique [0002] Electromagnetic magnetic separator is still the mainstream equipment for strong magnetic separation. Since the electromagnet needs an excitation power supply and a cooling system is needed to solve the heating problem of the coil, a large amount of conductive copper bars or copper tubes and Electrician pure iron not only has complex equipment structure, inconvenient maintenance, high price, but also high operating cost, while the permanent magnet can provide a stable magnetic field after only one magnetization, and do...

Problems solved by technology

[0011] In summary, although the current research on permanent magnet high-gradient magnetic separation technology has initially solved the problems of magnetic system structure, magnetic field strength, and blockage during the separation process, it has the conditions for initial application in industrial production, but in the actual application process There are still some outstanding problems in the following aspects: (1) The structure of the magnetic system is not reasonable, the field strength in the sorting area is low, and the magnetic energy of the permanent magnet is not fully utilized; (3) The sorting space is narrow, the equipment processing and manufacturing requirements are high, and the consumption of materials is large; (4) The magnetic field strength in the sorting area is uniform, and most of them use a single stainless steel expanded mesh or Magnetic gathering media such as steel wool cannot adapt to the separation of wide-grained and multi-magnetic minerals; (5) mechanical inclusions and blockage of magnetic gathering media often occur during the sorting process, resulting in deterioration of the separation technical indicators; (6) wet method During sorting, rinsing water is mostly used to reduce mechanical inclusions, and pressure water washing is mostly used for unloading magnetic materials, which consumes a lot of water and increases the production pressure of downstream processes; (7) Most of the sorting areas are invisible and difficult to monitor Real-time observation of sorting status
