A sea-going magnetic separator suitable for seawater beneficiation

Abstract

The invention discloses a ship magnetic separator suitable for seawater separation, which comprises a rack (6), a trough body (1), a permanent magnetic drum (3) and a driving device (2), a magnetic system (8) and a magnetic system fixing device (5). Two ends of a mandrel (7) are made of solid sectional anti-corrosive stainless steel, the middle hollow section and the end solid section of the mandrel (7) are in threaded connection and welded firmly, the two ends of the mandrel (7) are supported by a mandrel bases through copper sleeves (4) in a matching manner, and are in a mutual opposite axial stop design; and the rack (6) is designed to be in a frame structure, adopts high-strength structure carbon steel square tubes, and is in full contact connection with a deck through the bottom surfaces of two parallel beam bottoms. The permanent magnetic drum (3) is made of anti-corrosive stainless steel, and the outer surface of the rack (6) is sprayed with paint which is resistant to seawater corrosion. A feeder box (13) and the trough body (1) are integrally designed. The ship magnetic separator has excellent performance in wind resistance, bump prevention and salt fog prevention, can be installed on the ships operating on rivers and seas to recycle and select the strong magnetic iron minerals in river sand and sea sand.

Description

technical field [0001] The present invention relates to a permanent magnet drum type magnetic separator, in particular to a permanent magnet drum type wet magnetic separator composed of a permanent magnet drum and its driving mechanism, a tank body, a frame, etc. In the sea area, the strong magnetic iron minerals in the sea sand are recovered and sorted. Background technique [0002] As land iron ore resources become increasingly scarce in recent years, and the contradiction between supply and demand intensifies, the development of coastal and offshore iron ore resources is becoming increasingly urgent, and there is an urgent need to develop a magnetic separation equipment for sea surface operations. At present, the demand for iron concentrate powder is increasing day by day, and the scope of mining and beneficiating iron ore has been extended from land to water. The traditional permanent magnet drum magnetic separator can only be used on land due to its design and use envi...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing common magnetic separator cannot meet the requirements of sea mineral processing, and to provide a sea-going magnetic separator that is resistant to wind and waves, anti-turbulence, and anti-salt spray, and is suitable for seawater mineral processing.
